                                    AGREEMENT

         The parties agree as follows:

         SECTION 1. DEMAND REGISTRATION RIGHTS.

         (a) From and after the date of this  Agreement and to and including the
date that is the 10th  anniversary  of the date of this  Agreement,  subject  to
extension  pursuant  to  Section  4 (as so  extended  from  time  to  time,  the
"TERMINATION  DATE"),  on one or more  occasions  when the  Company  shall  have
received the written  request of a Stockholder or holders of at least  2,500,000
Registrable Shares in the aggregate (as such number of shares may be adjusted in
the event of any change in the  capital  stock of the Company by reason of stock
dividends,    split-ups,   reverse   split-ups,   mergers,    recapitalizations,
subdivisions,  conversions,  exchanges  of shares  or the  like)  that have been
acquired  directly or indirectly from Stockholder and to which rights under this
Section 1 shall have been assigned  pursuant to Section 14(a) (each such person,
when  requesting  registration  under  this  Section  1 or under  Section  2 and
thereafter in connection with any such registration,  being hereinafter referred
to as a "REGISTERING STOCKHOLDER"), the Company shall give written notice of the
receipt of such request to each




potential  Registering  Stockholder,  each  person  known by the Company to have
rights  under  Other   Agreements  with  respect  to  the  registration  of  the
disposition of shares of Company Common Stock (each such person, when requesting
registration  under this  Section 1 or Section 2, or similar  provisions  in the
Other Agreements, and thereafter in connection with any such registration, being
hereafter  referred  to as an "OTHER  REGISTERING  STOCKHOLDER")  and each other
person  known by the  Company to have rights  with  respect to the  registration
under the  Securities Act of the  disposition of securities of the Company.  The
Company shall use reasonable  best efforts as promptly as practicable to include
in a  Registration  Statement the  Registrable  Shares owned by the  Registering
Stockholders  and the Other  Registrable  Shares owned by the Other  Registering
Stockholders  (all  such  Registrable  Shares  and  Other  Registrable   Shares,
collectively,  "TRANSACTION  REGISTRABLE  SHARES")  that in each case shall have
been duly  specified  by such  Registering  Stockholders  and Other  Registering
Stockholders  by  written  notice  received  by the  Company  not later  than 20
Business  Days  after  the  Company  shall  have  given  written  notice  to the
Registering Stockholders and the Other Registering Stockholders pursuant to this
Section 1(a).

         (b)  If  the   Registering   Stockholders   initiating  a  request  for
registration of Registrable  Shares pursuant to Section 1(a) shall state in such
written notice that they intend to distribute the Transaction Registrable Shares
covered by their request by means of an underwritten offering, the Company shall
include such information in the written notice delivered by the Company pursuant
to Section 1(a). If, on the one hand, at the time the  Registering  Stockholders
deliver such written notice to the Company, the Registering Stockholders are the
Beneficial Owners of 20% or more of the shares of the Company Common Stock, then
the  Registering  Stockholders  shall  select the  managing  underwriter  of the
offering  and any  additional  investment  bankers  and  managers  to be used in
connection  with the  offering,  in each case with the  consent of the  Company,
which consent shall not be unreasonably withheld, conditioned or delayed. If, on
the other hand, at the time the  Registering  Stockholders  deliver such written
notice to the Company, the Registering Stockholders are the Beneficial Owners of
less than 20% of the shares of the Company Common Stock,  then the Company shall
select the managing  underwriter for the offering and any additional  investment
bankers and managers to be used in connection  with the  offering,  in each case
with  the  consent  of  the  Registering   Stockholders  and  Other  Registering
Stockholders  holding a majority of the Transaction  Registrable  Shares,  which
consent shall not be unreasonably withheld, conditioned or delayed.

         (c) Notwithstanding anything herein to the contrary:

              (1) The Company shall not be required to prepare and file pursuant
         to this  Section 1, and the Company  shall be entitled not to file and,
         if filed,  to withdraw a  Registration  Statement  including  less than
         2,500,000  Transaction  Registrable  Shares in the  aggregate  (as such
         number  of shares  may be  adjusted  in the event of any  change in the
         capital stock of the Company by reason of stock  dividends,  split-ups,
         reverse   split-ups,    mergers,    recapitalizations,    subdivisions,
         conversions, exchanges of shares or the like);

              (2)  subject to the  following  clause (3) and Section  2(b),  the
         Company  shall not be  required  to prepare  and file  pursuant to this
         Section 1 more than eight

                                        2


         (8)  Registration   Statements  in  the  aggregate;   provided  that  a
         Registration  Statement  shall be deemed not to have been  prepared and
         filed if (A) the  Registration  Statement (i) is --------  withdrawn by
         Registering  Stockholders  pursuant  to  Section  4(c) or (ii) does not
         become  effective  for any  other  reason  except  (x)  the  withdrawal
         therefrom  of  30%  or  more  of  the  Transaction  Registrable  Shares
         requested  to  be  included  in  such  registration  statement  or  the
         determination  by  Registering   Stockholders  and  Other   Registering
         Stockholders owning 30% or more of such Transaction  Registrable Shares
         not to proceed with the  contemplated  distribution of such Transaction
         Registrable Shares or (y) the withdrawal of the Registration  Statement
         by the Company  pursuant to Section  1(c)(1),  (B) the Company fails to
         use  reasonable  best  efforts to cause the  Registration  Statement to
         remain  effective under the Securities Act and the Prospectus to remain
         current  during the entire  period  referred to in Section 3(e), as the
         same may be  extended  pursuant  to Section  4(d),  or (C) the  Company
         withdraws the Registration  Statement  pursuant to Section 5 before the
         Registering  Stockholders  have  sold all the  Transaction  Registrable
         Shares  owned by them in  accordance  with the  manner of  distribution
         contemplated  by  the  Registration  Statement  with  respect  to  such
         Transaction Registrable Shares;

              (3) the  Company  shall  not be  required  to  prepare  and file a
         Registration  Statement  pursuant  to this  Section 1 during the period
         from the date of  filing of a  registration  statement  of the  Company
         involving  an  underwritten  offering of any Equity  Securities  of the
         Company  to the  date  that  is the  earlier  of (A)  the  date  of the
         withdrawal  of the  registration  statement  or the request to file the
         registration   statement  by  the  security   holder   requesting   the
         registration  and (B) the date that is 90 days  following the effective
         date of the registration statement;

              (4) if a requested  registration  pursuant to this Section 1 shall
         involve an underwritten offering, and if the managing underwriter shall
         advise  the  Company,  the  Registering   Stockholders  and  the  Other
         Registering Stockholders in writing that, in its opinion, the number of
         Transaction   Registrable   Shares  proposed  to  be  included  in  the
         registration is so great as to adversely affect the offering, including
         the price at which the  Transaction  Registrable  Shares could be sold,
         the Company shall  include in the  registration  the maximum  number of
         securities  which it is so  advised  can be sold  without  the  adverse
         effect, allocated as follows:

                    (A) first, all Transaction Registrable Shares duly requested
               to be included in the registration,  allocated pro rata among all
               Registering  Stockholders and Other  Registering  Stockholders on
               the  basis of the  relative  number  of  Transaction  Registrable
               Shares that each  Registering  Stockholder  or Other  Registering
               Stockholder  shall  have duly  requested  to be  included  in the
               registration or such other basis as the Registering  Stockholders
               and the Other Registering Stockholders shall agree; and

                                       3


                    (B) second,  any other securities  proposed to be registered
               by the Company other than for its own account, including, without
               limitation,  securities  proposed to be registered by the Company
               pursuant to the exercise by any person  other than a  Registering
               Stockholder or an Other Registering Stockholder of a "piggy-back"
               right  requesting  the  registration  of shares  of Common  Stock
               pursuant to an agreement  with the Company in existence as of the
               date of this Agreement that expressly  provides,  in effect, that
               the Company is required to include such shares of Common Stock in
               the Registration Statement;

               provided  that  if 30% or  more  of the  Transaction  Registrable
               Shares  requested  to be included in a  registration  pursuant to
               this  Section  1 are so  excluded  from any  registration  and an
               investment  banking firm of recognized  national  standing  shall
               advise the Company that the number of the Transaction Registrable
               Shares requested to be registered, at the time of the request and
               in light of the market conditions then prevailing, did not exceed
               the number that would have an adverse  effect on the  offering of
               such Transaction Registrable Shares, including the price of which
               such Transaction Registrable Shares could be sold, there shall be
               provided one additional  registration  under the preceding clause
               (2) in  respect  of each such  exclusion  or  series  of  related
               exclusions; and

               (5) before the  Registration  Statement  becomes  effective,  any
         Registering   Stockholder  may  withdraw  from  the   registration  any
         Transaction  Registrable  Shares owned by the Registering  Stockholder;
         provided that,  subject to Section  1(c)(1),  withdrawal of Transaction
         Registrable  Shares shall not relieve the Company from its  obligations
         under this  Agreement with respect to  Transaction  Registrable  Shares
         that are not withdrawn from the Registration Statement;

         SECTION 2.     PIGGY-BACK REGISTRATION RIGHTS.

         (a) From and after the date of this Agreement to and including the date
that is the 10th anniversary of the date of this Agreement, if the Company shall
determine  to register or qualify by a  registration  statement  filed under the
Securities Act and under any applicable  state  securities laws, any offering of
any Equity  Securities  of the Company,  other than an offering  with respect to
which a Registering  Stockholder shall have requested a registration pursuant to
Section 1, the Company shall give notice of such determination to each potential
Registering  Stockholder,  each potential Other Registering Stockholder and each
other  person  known  by  the  Company  to  have  rights  with  respect  to  the
registration  under the Securities  Act of the  disposition of securities of the
Company.   The  Company  shall  use  reasonable  best  efforts  as  promptly  as
practicable to include in a Registration  Statement the Transaction  Registrable
Shares  that in each case shall  have been duly  specified  by such  Registering
Stockholders  and Other  Registering  Stockholders by written notice received by
the Company not later than 20 Business  Days after the Company  shall have given
written  notice  to the  Registering  Stockholders  and  the  Other  Registering
Stockholders pursuant to this Section 2(a).

         (b) Notwithstanding anything herein to the contrary:

                                       4


               (1) the  Company  shall  not be  required  by this  Section  2 to
         include any  Registrable  Shares or Other  Registrable  Shares in (A) a
         registration  statement on Form S-4 or S-8 (or any successor form), (B)
         a registration  statement filed in connection with an exchange offer or
         other offering of securities  solely to the then existing  stockholders
         of the Company or (C) a registration statement required pursuant to the
         exercise by any person other than a Registering Stockholder or an Other
         Registering Stockholder of a "demand" right requesting the registration
         of shares of Company  Common Stock  pursuant to an  agreement  with the
         Company in existence as of the date of this  Agreement  that  expressly
         provides,  in effect,  that the Company may not include any Registrable
         Shares in the registration statement;

               (2) if a  registration  pursuant  to this  Section 2 involves  an
         underwritten   offering,   the  Company   shall   select  the  managing
         underwriter for the offering and any additional  investment bankers and
         managers  to be  used  in  connection  with  the  offering,  and if the
         managing  underwriter  advises  the  Company  in writing  that,  in its
         opinion,  the number of  securities  requested  to be  included  in the
         registration is so great as to adversely affect the offering, including
         the price at which the  securities  could be sold,  the  Company  shall
         include in the  registration  the maximum number of securities which it
         is so advised  can be sold  without the adverse  effect,  allocated  as
         follows:

                    (A) FIRST,  all securities  proposed to be registered by the

               "demand" right  requesting the  registration of shares of Company
               Common  Stock  pursuant  to an  agreement  with  the  Company  in

               of the  Company  other than those  referred  to in the  preceding
               clauses (A) and (B) shall be included in such registration unless
               all shares of Company Common Stock requested by such person to be
               included in such registration are so included; and

                    (D) FOURTH,  any other securities  proposed to be registered

               registered by the Company

                                       5

               right  requesting  the  registration  of shares of Company Common
               Stock  pursuant to an agreement  with the Company,  allocated pro
               rata  among  all  Registering  Stockholders,   Other  Registering
               Stockholders  and such other persons on the basis of the relative

               each Registering  Stockholder,  Other Registering  Stockholder or
               other   person  has  duly   requested  to  be  included  in  such
               registration;

               PROVIDED  that  if 30% or  more  of the  Transaction  Registrable
               Shares  requested  to be included in a  registration  pursuant to
               this  Section  2 are so  excluded  from any  registration  and an
               investment  banking firm of recognized  national  standing  shall
               advise the Company that the number of the Transaction Registrable
               Shares requested to be registered, at the time of the request and
               in light of the market conditions then prevailing, did not exceed

         PROVIDED  that,   subject  to  Section   2(b)(4),   the  withdrawal  of
         Transaction  Registrable  Shares shall not relieve the Company from its
         obligations   under  this   Agreement   with  respect  to   Transaction
         Registrable  Shares  that  are  not  withdrawn  from  the  Registration
         Statement; and

               (4) the Company may  withdraw the  Registration  Statement at any

         SECTION 3. REGISTRATION  PROVISIONS.  With respect to each registration
pursuant to this Agreement:

         (a) Notwithstanding  anything herein to the contrary, the Company shall
not be required to include in any  registration  any of the  Registrable  Shares
owned by a  Registering  Stockholder  if (1) the  Company  shall  deliver to the
Registering Stockholder an opinion, satisfactory in form, scope and substance to
the  Registering  Stockholder  and addressed to the  Registering  Stockholder by
legal counsel  satisfactory to the Registering  Stockholder,  to the effect that
the  distribution  of  such  Registrable  Shares  proposed  by  the  Registering
Stockholder  is  exempt  from  registration  under  the  Securities  Act and all
applicable  state  securities  laws,  (2) such  Registering  Stockholder  or any
underwriter of such Registrable  Shares shall fail to furnish to the Company the
information in respect of the distribution of such  Registrable  Shares that may
be required under this Agreement to be furnished by the Registering  Stockholder
or the  underwriter  to the  Company  or (3) if such  registration  involves  an
underwritten offering, such

                                       6



Registrable  Shares are not included in such  underwritten  offering on the same
terms and conditions as shall be applicable to the other  securities  being sold
through underwriters in the registration or the Registering Stockholder fails to
enter into an  underwriting  agreement in customary form with the underwriter or
underwriters selected for such underwritten offering.

         (b) The Company shall make available for inspection by each Registering
Stockholder  participating in the registration,  each underwriter of Transaction
Registrable  Shares owned by the Registering  Stockholder  and their  respective
accountants,  counsel and other representatives all financial and other records,
pertinent  corporate  documents  and  properties  of the  Company  as  shall  be
reasonably   necessary   to  enable  them  to  exercise   their  due   diligence
responsibility in connection with each  registration of Transaction  Registrable
Shares  owned by the  Registering  Stockholder,  and shall  cause the  Company's
officers, directors and employees to supply all information reasonably requested
by any such person in connection with such  registration;  provided that records
and documents which the Company  determines,  in good faith,  after consultation
with  counsel for the Company and  counsel for the  Registering  Stockholder  or
underwriter,  as the case may be, to be confidential  and which it notifies such
persons are confidential  shall not be disclosed to them, except in each case to
the extent that (1) the  disclosure of such records or documents is necessary to
avoid or correct a misstatement or omission in the Registration Statement or (2)
the release of such records or  documents  is ordered  pursuant to a subpoena or
other order from a court of competent jurisdiction. Each Registering Stockholder
shall,  upon learning that disclosure of any such records or documents 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 and to
prevent disclosure of any such records or documents deemed confidential.

         (c) Each Registering  Stockholder  shall furnish,  and shall cause each
underwriter  of  Transaction   Registrable   Shares  owned  by  the  Registering
Stockholder to be distributed  pursuant to the  registration to furnish,  to the
Company in writing  promptly  upon the request of the  Company  the  information
regarding the  Registering  Stockholder  or the  underwriter,  the  contemplated
distribution of the  Transaction  Registrable  Shares and the other  information
regarding  the proposed  distribution  by the  Registering  Stockholder  and the
underwriter that shall be required in connection with the proposed  distribution
by the applicable securities laws of the United States of America and the states
thereof  in which the  Transaction  Registrable  Shares are  contemplated  to be
distributed.  The information  furnished by any  Registering  Stockholder or any
underwriter   shall  be  certified  by  the   Registering   Stockholder  or  the
underwriter,  as the case may be, and shall be stated to be specifically for use
in connection with the registration.

         (d) The Company shall use  reasonable  best efforts to prepare and file
with  the  Securities  and  Exchange  Commission  the  Registration   Statement,
including the  Prospectus,  and each  amendment  thereof or supplement  thereto,
under the Securities Act and as required under any applicable  state  securities
laws,  on the form that is then  required or available for use by the Company to
permit each Registering Stockholder, upon the effective date of the Registration
Statement,   to  use  the  Prospectus  in  connection   with  the   contemplated
distribution  by the  Registering  Stockholder  of the  Transaction  Registrable
Shares requested to be so registered. A registration pursuant to Section 1 shall
be effected  pursuant to Rule 415 (or any similar provision then in force) under
the Securities Act if the manner of distribution contemplated by the

                                       7


Registering  Stockholder  initiating  the  request for such  registration  shall
include an offering on a delayed or continuous  basis. The Company shall furnish
to each Registering  Stockholder  drafts of the  Registration  Statement and the
Prospectus  and each  amendment  thereof or  supplement  thereto  for its timely
review prior to the filing thereof with the  Securities and Exchange  Commission
and shall use its reasonable best efforts to reflect in each such document, when
so filed with the  Securities  and  Exchange  Commission,  such  comments as the
Registering  Stockholder  reasonably may propose. If any Registration  Statement
refers to any Registering  Stockholder by name or otherwise as the holder of any
securities of the Company but such  reference is not required by the  Securities
Act or  any  similar  federal  statute  then  in  force,  then  the  Registering
Stockholder shall have the right to require, the deletion of such reference. The
Company shall deliver to each  Registering  Stockholder,  without  charge,  such
number  of  copies  of  the   Registration   Statement  and  each  amendment  or
post-effective  amendment  thereof  and such  number of copies of each  document
incorporated therein by reference as the Registering  Stockholder may reasonably
request.  If the registration shall have been initiated solely by the Company or
shall not have been  initiated by a Registering  Stockholder,  the Company shall
not  be  obligated  to  prosecute  the   registration,   and  may  withdraw  the
Registration  Statement at any time prior to the effectiveness  thereof,  if the
Company  shall  determine  in good faith not to  proceed  with the  offering  of
securities  included in the  Registration  Statement.  In all other  cases,  the
Company shall use reasonable best efforts to cause the Registration Statement to
become effective and, as soon as practicable  after the  effectiveness  thereof,
shall deliver to each Registering  Stockholder evidence of the effectiveness and
such number of copies of the Prospectus including any preliminary prospectus and
each amendment thereof or supplement thereto as the Registering  Stockholder may
reasonably  request.  The  Company  consents  to  the  use by  each  Registering
Stockholder of each Prospectus and each amendment thereof and supplement thereto
in connection with the distribution,  in accordance with this Agreement,  of the
Transaction  Registrable  Shares  owned  by  the  Registering  Stockholder.   In
addition,  the Company shall qualify or register  under the  securities  laws or
blue sky laws of such states as may be reasonably  requested by each Registering
Stockholder  with  respect  to  the  Transaction   Registrable   Shares  of  the
Registering  Stockholder  that  shall  have been  included  in the  Registration
Statement,  and to continue such  registration or qualification in effect for so
long as such Registration Statement remains in effect; provided that the Company
shall not be obligated  to file any general  consent to service of process or to
qualify  as a foreign  corporation  in any state in which it is not  subject  to
process or  qualified as of the date of the  request.  The Company  shall advise
each Stockholder and each Registering Stockholder in writing, promptly after the
occurrence  of any of the  following,  of (1)  the  filing  of the  Registration
Statement or any  Prospectus,  or any amendment  thereof or supplement  thereto,
with the  Securities  and  Exchange  Commission,  (2) the  effectiveness  of the
Registration Statement and any post-effective amendment thereto, (3) the receipt
by the Company of any communication from the Securities Exchange Commission with
respect  to the  Registration  Statement  or the  Prospectus,  or any  amendment
thereof or supplement thereto,  including,  without  limitation,  any stop order
suspending the effectiveness  thereof, any comments with respect thereto and any
requests for amendments or supplements and (4) the receipt by the Company of any
notification  with respect to the suspension of the qualification of Transaction
Registrable  Shares  owned  by the  Registering  Stockholders  for  sale  in any
jurisdiction  or the  initiation  or  threatening  of any  proceeding  for  such
purpose.

                                       8


         (e) The  Company  shall  use  reasonable  best  efforts  to  cause  the
Registration  Statement to remain  effective  under the  Securities  Act and the
Prospectus  to remain  current,  including  the filing of necessary  amendments,
post-effective  amendments  and  supplements,  and shall furnish  copies of such
amendments,   post-effective  amendments  and  supplements  to  the  Registering
Stockholders,  so as to permit the  Registering  Stockholders  to distribute the
Transaction  Registrable  Shares  owned by them in their  respective  manner  of
distribution during their respective  contemplated periods of distribution,  but
in no event longer than the earlier of six consecutive months from the effective
date of the  Registration  Statement and the consummation of the distribution of
the Transaction Registrable Shares included in such registration;  provided that
the  period  shall be  increased  by the  number  of days  that any  Registering
Stockholder  shall have been  required  by Section 4 to refrain  from  disposing
under the  registration any of the Transaction  Registrable  Shares owned by the
Registering   Stockholder.   During  such  respective  contemplated  periods  of
distribution, the Company shall comply with the provisions of the Securities Act
applicable to it with respect to the disposition of all Transaction  Registrable
Shares owned by the  Registering  Stockholders  that shall have been included in
the  Registration  Statement in accordance  with their  respective  contemplated
manner  of  disposition  by  the  Registering  Stockholders  set  forth  in  the
Registration Statement, the Prospectus or the supplement, as the case may be.

         (f) Any obligation of the Company under this  Agreement,  including any
obligation  to use its  reasonable  best  efforts  or take such  actions  as are
reasonably  required  shall not  preclude  the Company from taking any action or
omitting to take any action (other than omitting to file  necessary  amendments,
post-effective  amendments and supplements if a Suspension Notice or Termination
Notice is not then in effect  pursuant to Section 4 or Section 5,  respectively)
that would  result in the Company  issuing a  Suspension  Notice or  Termination
Notice.

         (g) The Company shall notify each Registering Stockholder,  at any time
when a prospectus  with respect to the Transaction  Registrable  Shares owned by
the  Registering  Stockholders  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  (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, but subject to Sections 4 and 5, the Company
shall use  reasonable  best efforts to prepare and file with the  Securities and
Exchange Commission an amendment or supplement to the Registration  Statement or
the  Prospectus  so that,  as  thereafter  delivered to the  purchasers  of such
Transaction  Registrable  Shares,  such  Prospectus  will not contain any untrue
statement of a material fact or omit to state a material fact  necessary to make
the  statements  therein,  in light of the  circumstances  under which they were
made,  not   misleading.   The  Company  also  shall  notify  each   Registering
Stockholder,  when the Company becomes aware of the occurrence  thereof,  of the
issuance by the  Securities and Exchange  Commission of an order  suspending the
effectiveness  of  the  Registration   Statement;  as  promptly  as  practicable
thereafter,  but subject to Sections 4 and 5, the Company  shall use  reasonable
best efforts to obtain the  withdrawal  of such order at the  earliest  possible
moment.

                                       9


         (h) If requested by any  Registering  Stockholder  or an underwriter of
Transaction Registrable Shares owned by the Registering Stockholder, the Company
shall as  promptly  as  practicable  prepare  and file with the  Securities  and
Exchange Commission an amendment or supplement to the Registration  Statement or
the Prospectus containing such information as the Registering Stockholder or the
underwriter  requests to be included  therein,  including,  without  limitation,
information with respect to the Transaction Registrable Shares being sold by the
Registering  Stockholder  to the  underwriter,  the  purchase  price  being paid
therefor by such underwriter and other terms of the underwritten offering of the
Transaction Registrable Shares to be sold in such offering.

         (i) Each  Stockholder  shall (1) offer to sell or otherwise  distribute
Registrable  Shares in reliance  upon a  registration  contemplated  pursuant to
Section 1 or 2 only (A) if the Stockholder is a Registering  Stockholder and the
Registrable Securities are Transaction  Registrable Securities and (B) after the
related  Registration  Statement  shall have been filed with the  Securities and
Exchange  Commission,  (2) sell or otherwise  distribute  Registrable  Shares in
reliance upon such  registration  only (A) if the  Stockholder  is a Registering
Stockholder   and  the  Registrable   Securities  are  Transaction   Registrable
Securities and (B) the related  Registration  Statement is then effective  under
the Securities Act, (3) not sell or otherwise distribute Transaction Registrable
Securities in reliance upon a registration contemplated by Section 1 or 2 during
any  period  specified  in a  Suspension  Notice  delivered  to the  Registering
Stockholder  pursuant  to  Section 4 or after  receiving  a  Termination  Notice
pursuant to Section 5 (until the  Registering  Stockholder  shall have  received
written notice from the Company  pursuant to Section 3(d) that the  registration
of such  Transaction  Registrable  Shares is again  effective),  (4)  distribute
Transaction   Registrable   Shares  only  in  accordance   with  the  manner  of
distribution  contemplated  by the  Prospectus  with respect to the  Transaction
Registrable  Shares owned by the  Registering  Stockholder and (5) report to the
Company  distributions  made  by  the  Registering  Stockholder  of  Transaction
Registrable Shares pursuant to the Prospectus.  Each Registering Stockholder, by
participating in a registration  pursuant to this Agreement,  acknowledges  that
the remedies of the Company at law for failure by the Registering Stockholder to
comply with the undertaking  contained in this paragraph (i) would be inadequate
and that the failure  would not be adequately  compensable  in damages and would
cause  irreparable harm to the Company,  and therefore agrees that  undertakings
made by the  Registering  Stockholder in this paragraph (i) may be  specifically
enforced.

         (j)  If  the  registration  involves  an  underwritten  offering,  each
Registering Stockholder shall cause the underwriter or underwriters selected for
such underwriting to enter into an underwriting  agreement in customary form and
shall  enter  into  such   Underwriting   Agreement  with  such  underwriter  or
underwriters.

         (k) If the registration involves an underwritten  offering, the Company
shall  enter  into  an  underwriting   agreement  in  customary  form  with  the
underwriter or underwriters  selected for such underwriting and shall deliver to
each  Registering  Stockholder,  its counsel and each underwriter of Transaction
Registrable  Shares  owned by the  Registering  Stockholders  to be  distributed
pursuant to such registration, the certificates, opinions of counsel and comfort
letters  that  are  customarily   delivered  in  connection  with   underwritten
offerings.

                                       10


         (l) Before sales of Transaction Registrable Shares under a Registration
Statement,  the Company shall  cooperate with each  Registering  Stockholder and
each  underwriter of  Transaction  Registrable  Shares owned by the  Registering
Stockholder to facilitate the timely  preparation  and delivery of  certificates
(not bearing any restrictive legends)  representing the Transaction  Registrable
Shares  to  be  sold  under  the  Registration  Statement  and  to  enable  such
Transaction  Registrable  Shares to be in such  denominations  and registered in
such names as the Registering Stockholder or the underwriter may request.

         (m) The Company  shall use  reasonable  best efforts to (1) comply with
all applicable rules and regulations of the Securities and Exchange  Commission,
and  (2)  make  available  to  its   securityholders,   as  soon  as  reasonably
practicable, an earning statement covering the period of at least twelve months,
but not more than eighteen months, beginning with the first calendar month after
the effective date of the Registration Statement,  which earning statement shall
satisfy the provisions of Section 11(a) of the Securities Act.

         (n) The  Company  shall  use  reasonable  best  efforts  to  cause  the
Transaction Registrable Shares to be listed on each national securities exchange
on which Company Common Stock shall then be listed,  if any, and to be qualified
for  inclusion  in the  NASDAQ/National  Market,  as the case may be, if Company
Common Stock is then so qualified,  and in each case if the listing or inclusion
of the Transaction  Registrable Shares is then permitted under the rules of such
national securities exchange or the NASD, as the case may be.

Stockholder  and the  underwriter  and each  person,  if any,  who  controls the
Registering  Stockholder,  any  partner in the  Registering  Stockholder  or the
underwriter within the meaning of Section 15 (or any successor provision) of the
Securities Act, and their  respective  successors,  against all claims,  losses,
damages and liabilities to third parties (or actions in respect thereof) arising
out of or based on any untrue  statement  (or  alleged  untrue  statement)  of a
material fact contained in the Registration Statement or the Prospectus or other
document incident thereto or 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,  and shall  reimburse each such  Registering
Stockholder and each other person indemnified  pursuant to this Section 7(a) for
any  legal  and any  other  expenses  reasonably  incurred  in  connection  with
investigating or defending any such claim,  loss,  damage,  liability or action;
provided that the Company shall not be liable in any case to the extent that any
such claim,  loss,  damage or liability  arises out of or is based on any untrue
statement or omission based upon written information furnished to the Company by
the Registering  Stockholder or the underwriter of such Transaction  Registrable
Shares specifically for use in the Registration Statement or the Prospectus.

         (b) Each  Registering  Stockholder,  by participating in a registration
pursuant to this Agreement, thereby agrees to indemnify and to hold harmless the
Company and its officers and directors and each person, if any, who controls any
of them within the  meaning of Section 15 (or any  successor  provision)  of the
Securities Act, and their  respective  successors,  against all claims,  losses,
damages and liabilities to third parties (or actions in respect thereof) arising
out of or based upon any untrue  statement  (or alleged  untrue  statement) of a
material fact contained in the Registration Statement or the Prospectus or other
document incident thereto or any omission (or alleged omission) to state therein
a material fact required to be stated therein or necessary to

                                       15


make the statements therein not misleading,  and shall reimburse the Company and
each other  person  indemnified  pursuant to this Section 7(b) for any legal and
any other  expenses  reasonably  incurred in connection  with  investigating  or
defending any such claim, loss, damage,  liability or action;  provided that (x)
this  Section  7(b)  shall  apply  only if (and  only to the  extent  that)  the
statement  or  omission  was  made  in  reliance  upon  and in  conformity  with
information  furnished to the Company in writing by the Registering  Stockholder
specifically for use in the Registration  Statement or the Prospectus and (y) in
no event shall the liability of a Registering  Stockholder  under this Section 7
exceed the amount of the gross proceeds paid to the  Registering  Stockholder in
consideration  of the sale of Transaction  Registrable  Shares  pursuant to such
registration.

         (c)  If  any  action  or   proceeding   (including   any   governmental
investigation or inquiry) shall be brought,  asserted or threatened  against any
person  indemnified under this Section 7, the indemnified  person shall promptly
notify the  indemnifying  party in  writing,  and the  indemnifying  party shall
assume the defense of the action or  proceeding,  including  the  employment  of
counsel  satisfactory to the indemnified person and the payment of all expenses.
The indemnified  person shall have the right to employ  separate  counsel in any
action  or  proceeding  and to  participate  in the  defense  of the  action  or
proceeding, but the fees and expenses of that counsel shall be at the expense of
the indemnified person unless:

               (1) the  indemnifying  party  shall have agreed to pay those fees
         and expenses; or

               (2) the  indemnifying  party  shall  have  failed to  assume  the
         defense of the  action or  proceeding  or shall  have  failed to employ
         counsel reasonably satisfactory to the indemnified person in the action
         or proceeding; or

               (3) the named parties to the action or proceeding  (including any
         impleaded   parties)  include  both  the  indemnified  person  and  the
         indemnifying  party, and the indemnified person shall have been advised
         by counsel  that there may be one or more legal  defenses  available to
         the  indemnified  person that are different from or additional to those
         available to the indemnifying  party (in which case, if the indemnified
         person  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 or proceeding on behalf of the indemnified person; it being
         understood,   however,  that  the  indemnifying  party  shall  not,  in
         connection   with  any  one  action  or   proceeding  or  separate  but
         substantially  similar or related  actions 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  at any time for the  indemnified
         person,  which firm shall be designated  in writing by the  indemnified
         person).

The  indemnifying  party shall not be liable for any settlement of any action or
proceeding effected without its written consent, but if settled with its written
consent, or if there be a final judgment for the plaintiff in any such action or
proceeding,  the  indemnifying  party  shall  indemnify  and hold  harmless  the
indemnified  person  from and  against  any loss or  liability  by reason of the
settlement or judgment.

                                       16


         (d)  If  the  indemnification   provided  for  in  this  Section  7  is
unavailable  to an  indemnified  person  (other  than by  reason  of  exceptions
provided in this Section 7) in respect of losses, claims,  damages,  liabilities
or expenses  referred to in this  Section 7, then each  applicable  indemnifying
party, in lieu of indemnifying the indemnified  person,  shall contribute to the
amount  paid or payable  by the  indemnified  person as a result of the  losses,
claims, damages, liabilities or expenses in such proportion as is appropriate to
reflect the relative fault of the indemnifying  party on the one hand and of the
indemnified  person on the other in connection  with the statements or omissions
which resulted in the losses, claims,  damages,  liabilities or expenses as well
as any  other  relevant  equitable  considerations.  The  relative  fault of the
indemnifying  party on the one hand and of the  indemnified  person on the other
shall be determined  by reference to, among other things,  whether the untrue or
alleged untrue  statement of a material fact or the omission or alleged omission
to state a material  fact relates to  information  supplied by the  indemnifying
party or by the  indemnified  person  and by  these  persons'  relative  intent,
knowledge,  access to  information  and  opportunity  to correct or prevent such
statement or omission. The parties agree that it would not be just and equitable
if  contribution  pursuant  to this  Section  7(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 sentence.
The  amount  paid or  payable  by a person  as a result of the  losses,  claims,
damages,  liabilities and expenses shall be deemed to include any legal or other
fees  or  expenses   reasonably  incurred  by  the  person  in  connection  with
investigating or defending any action or claim. Notwithstanding in the foregoing
to the contrary,  no  Registering  Stockholder  or  underwriter  of  Transaction
Registrable  Shares owned by the  Registering  Stockholder  shall be required to
contribute  any  amount in excess of the  amount by which (1) in the case of the
Registering Stockholder,  the gross proceeds paid to the Registering Stockholder
in  consideration  of the  sale  pursuant  to the  registration  of  Transaction
Registrable Shares owned by it or (2) in the case of the underwriter,  the total
price  at  which  such  Transaction  Registrable  Shares  purchased  by  it  and
distributed to the public were offered to the public exceeds,  in any such case,
the amount of any damages that the Registering  Stockholder or  underwriter,  as
the case may be, has  otherwise  been required to pay by reason of any untrue or
alleged   untrue   statement  or  omission.   No  person  guilty  of  fraudulent
representation (within the meaning of Section 11(f) of the Securities Act) shall
be entitled to contribution from any person who is not guilty of such fraudulent
misrepresentation.

         (e)  Each  Registering  Stockholder  participating  in  a  registration
pursuant  to  Section  1  shall  cause  each   underwriter  of  any  Transaction
Registrable  Shares  owned  by the  Registering  Stockholder  to be  distributed
pursuant  to  the   registration  to  agree  in  writing  on  terms   reasonably
satisfactory  to the Company to indemnify  and to hold  harmless the Company and
its officers  and  directors  and each person,  if any, who controls any of them
within the meaning of Section 15 (or any similar provision then in force) of the
Securities Act, and their  respective  successors,  against all claims,  losses,
damages and liabilities to third parties (or actions in respect thereof) arising
out of or based upon any untrue  statement  (or alleged  untrue  statement) of a
material fact contained in the Registration Statement or the Prospectus or other
document incident thereto or 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,  and to reimburse the Company and each other
person indemnified  pursuant to the agreement for any legal or any other expense
reasonably  incurred in connection  with  investigating  or defending any claim,
loss, damage,  liability or action; provided that the agreement shall apply only
if (and only to the extent 

                                       17


that) the statement or omission was made in reliance upon and in conformity with
information furnished to the Company in writing by the underwriter  specifically
for use in the Registration Statement or the Prospectus.

         SECTION 8.     TRANSFER RESTRICTIONS.

         (a) Each Stockholder  agrees that before any sale or other  disposition
of any Registrable  Shares or the Warrant other than in a sale registered  under
the  Securities  Act or pursuant to Rule 144 or 144A (or any similar  provisions
then in force)  under the  Securities  Act (unless  the Company  shall have been
advised by counsel that the sale does not meet the  requirements  of Rule 144 or
Rule 144A, as the case may be, for such sale), it will deliver to the Company an
opinion  of  counsel,  in form  and  substance  reasonably  satisfactory  to the
Company, to the effect that such registration is unnecessary.

         (b)        (1) Except as  provided to the  contrary in this  Section 8,
         each  instrument  or  certificate   evidencing  or   representing   any
         Registrable  Shares  that is  transferred  to any person  other than an
         affiliate of Anschutz or AFIC, shall bear legends  substantially in the
         following form:

                    "THE SHARES  REPRESENTED BY THIS  CERTIFICATE  HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
         OFFERED,   SOLD,   TRANSFERRED  OR  OTHERWISE  DISPOSED  OF  EXCEPT  IN
         COMPLIANCE   WITH  SAID  ACT.  THE  SHARES  ARE  ALSO  SUBJECT  TO  THE
         RESTRICTIONS  STATED IN A  REGISTRATION  RIGHTS  AGREEMENT  DATED AS OF
         APRIL  18,  1999,  A COPY OF  WHICH  IS ON FILE  AT THE  OFFICE  OF THE
         SECRETARY OF THE COMPANY."

                    (2) Except as  provided to the  contrary in this  Section 8,
         each instrument or certificate  evidencing or representing  the Warrant
         that is  transferred  to any person other than an affiliate of Anschutz
         or AFIC, shall bear legends substantially in the following form:

                    "THE WARRANT  REPRESENTED BY THIS CERTIFICATE AND THE SHARES
         OF  COMMON  STOCK  ISSUABLE  UPON  THE  EXERCISE  HEREOF  HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
         OFFERED,   SOLD,   TRANSFERRED  OR  OTHERWISE  DISPOSED  OF  EXCEPT  IN
         COMPLIANCE WITH SAID ACT. THIS WARRANT AND SUCH SHARES ARE ALSO SUBJECT
         TO THE RESTRICTIONS  STATED IN A REGISTRATION RIGHTS AGREEMENT DATED AS
         OF APRIL  18,  1999,  A COPY OF WHICH IS ON FILE AT THE  OFFICE  OF THE
         SECRETARY OF THE COMPANY."

         (c) The Company  acknowledges  that it has already  removed the legends
from the instruments  representing  the  Registrable  Shares and Warrant held by
Anschutz or AFIC as of the date of this  Agreement.  If any other  holder of any
Registrable Shares or the Warrant shall

                                       18


request in writing that the Company  remove any or all of the legends  stated in
Section 8(b) from the  instruments or  certificates  evidencing or  representing
such  Registrable  Shares or the Warrant,  as the case may be, then,  as soon as
practicable  following  the later of the date of receipt of such request and the
date of receipt of such  instruments or certificates  bearing such legends,  the
Company  shall issue and  deliver to the  registered  owner of such  Registrable
Shares  or the  Warrant,  as the  case  may  be,  or its  registered  transferee
instruments or certificates  evidencing or representing such Registrable  Shares
or the  Warrant,  as the case may be,  without  such  legends if either (1) such
substitute instruments or certificates are issued in connection with a sale that
is registered  under the  Securities  Act or (2) the holder of such  Registrable
Shares or the Warrant has received  either an opinion of counsel,  which opinion
and counsel shall be reasonably  satisfactory to  Stockholder,  or a "no-action"
letter  obtained by the holder  from the staff of the  Securities  and  Exchange
Commission,  to the effect that the  restrictions  imposed by Rule 144 under the
Securities Act no longer apply to such Registrable Shares or the Warrant, as the
case may be.

         SECTION 9.     EXEMPT SALES.

         (a) The Company shall make all filings with the Securities and Exchange
Commission  required  by Rule 144(c) (or any  similar  provision  then in force)
under the Securities Act to permit the sale of Registrable  Shares by any holder
thereof  (other than an Affiliate of the Company) to satisfy the  conditions  of
Rule 144 (or any similar provision then in force).  The Company shall,  promptly
upon the written  request of the holder of Registrable  Shares,  deliver to such
holder a written  statement as to whether the Company has complied with all such
filing requirements.

         (b) Before sales of  Registrable  Shares or the Warrant  proposed to be
sold  pursuant  to an  exemption  from  the  registration  requirements  of  the
Securities Act, the Company shall,  subject to Section 8(c),  cooperate with the
holder  of such  Registrable  Shares  or the  Warrant,  as the case  may be,  to
facilitate the timely  preparation and delivery of certificates (not bearing any
restrictive  legends)  representing such Registrable  Shares or Warrant,  as the
case may be, in  connection  with the  closing  of the sales and to enable  such
Registrable  Shares  or  the  Warrant,  as  the  case  may  be,  to be  in  such
denominations and registered in such names as the holder may request.

         SECTION  10.  MERGER,  CONSOLIDATION,  EXCHANGE,  ETC.  In  the  event,
directly  or  indirectly,  (1)  the  Company  shall  merge  with  and  into,  or
consolidate  with, any other person or (2) any person shall merge with and into,
or consolidate,  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 Shares or the securities issuable
upon  exercise of the Warrant  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 other person shall be bound by the provisions of this
Agreement and the term the "Company" shall thereafter be deemed to refer to such
other person.

         SECTION 11. NOTICES. All notices,  requests and other communications to
any party under this Agreement shall be in writing.  Communications  may be made
by telecopy or similar writing.  Each communication  shall be given to the party
at its address stated on the

                                       19


signature  pages of this  Agreement  or at any  other  address  as the party may
specify for this purpose by notice to the other party. Each communication  shall
be effective (1) if given by telecopy,  when the telecopy is  transmitted to the
proper address and the receipt of the transmission is confirmed, (2) if given by
mail,  72 hours  after the  communication  is  deposited  in the mails  properly
addressed  with first class postage  prepaid or (3) if given by any other means,
when delivered to the proper address and a written  acknowledgement  of delivery
is received.

         SECTION 12. NO WAIVERS;  REMEDIES.  No failure or delay by any party in
exercising any right, power or privilege under this Agreement shall operate as a
waiver of the right,  power or  privilege.  A single or partial  exercise of any
right,  power or privilege  shall not preclude any other or further  exercise of
the right,  power or  privilege  or the  exercise of any other  right,  power or
privilege.  The  rights  and  remedies  provided  in  this  Agreement  shall  be
cumulative and not exclusive of any rights or remedies provided by law.

         SECTION 13. AMENDMENTS, ETC. No amendment, modification, termination or
waiver of any provision of this Agreement,  and no consent to any departure by a
party to this Agreement from any provision of this Agreement, shall be effective
unless it shall be in writing  and signed and  delivered  by the other  party to
this Agreement, and then it shall be effective only in the specific instance and
for the specific purpose for which it is given.

         SECTION 14. SUCCESSORS AND ASSIGNS.

         (a) Each holder of Registrable  Shares or the Warrant may assign to any
transferee of Registrable Shares or the Warrant,  as the case may be, its rights
and delegate to the transferee its obligations  under this Agreement  including,
without  limitation,  the rights of  assignment  pursuant  to this  Section  14;
provided that (i) any assignment of rights under Section 1 of one or more demand
registration  right  must  indicate  in writing  the number of demand  rights so
assigned and the Company must receive  notice of such  assignment  and (ii) such
transferee  shall accept such rights and assume such obligations for the benefit
of  the  Company  by  written  instrument,  in  form  and  substance  reasonably
satisfactory  to the  Company.  Thereafter,  without any  further  action by any
person,  all  references  in this  Agreement  to the holder of such  Registrable
Shares or the Warrant, as the case may be, and all comparable references,  shall
be  deemed to be  references  to the  transferee,  and the  transferor  shall be
released from each  obligation or liability under this Agreement with respect to
the Registrable Shares or the Warrant so transferred.

         (b) The provisions of this Agreement shall be binding upon and inure to
the benefit of the parties to this Agreement,  the express beneficiaries thereof
and  their  respective  permitted  heirs,   executors,   legal  representatives,
successors and assigns, and no other person.

         SECTION 15.  GOVERNING  LAW.  This  Agreement  shall be governed by and
construed in accordance  with the internal laws of the State of New York without
regard to principles of conflict of law.

                                       20


         SECTION 16. COUNTERPARTS;  EFFECTIVENESS.  This Agreement may be signed
in any number of counterparts, each of which shall be an original, with the same
effect as if all signatures were on the same instrument.

         SECTION 17. SEVERABILITY OF PROVISIONS. Any provision of this Agreement
that is  prohibited  or  unenforceable  in any  jurisdiction  shall,  as to that
jurisdiction,   be   ineffective   to  the   extent   of  the   prohibition   or
unenforceability without invalidating the remaining provisions of this Agreement
or  affecting  the  validity or  enforceability  of the  provision  in any other
jurisdiction.

         SECTION 18. HEADINGS AND REFERENCES. Section headings in this Agreement
are included for the  convenience of reference only and do not constitute a part
of  this  Agreement  for any  other  purpose.  References  to  parties,  express
beneficiaries and sections in this Agreement are references to the parties to or
the express  beneficiaries  and sections of this Agreement,  as the case may be,

agreement and  understanding  of the parties and supersedes all prior agreements
or understandings with respect to the subject matters of this Agreement.

         SECTION 20. SURVIVAL. Except as otherwise specifically provided in this
Agreement, each representation,  warranty or covenant of each party contained in

investigation  or notice to the  contrary  or any waiver by the other party of a
related  condition  precedent  to the  performance  by such  other  party  of an
obligation under this Agreement.

         SECTION 21.  NON-EXCLUSIVE  JURISDICTION.  Each party, and each express
beneficiary  of this  Agreement as a condition of its right to enforce or defend
any right under or in connection with this Agreement, (1) agrees that any Action

respect of its property,  generally and  unconditionally,  the  jurisdiction  of
those  courts and (3)  irrevocably  waives  any  objection,  including,  without
limitation,  any  objection  to the  laying of venue or based on the  grounds of

legal action in those jurisdictions.

constitute  Stockholder or any Registering  Stockholder an "affiliate" of any of
