incurred by the Company in  connection  with the  preparation  and filing of the
Registration  Statement under subparagraph 3(a) and in complying with applicable

(2) Trading Days of receipt thereof. The Company shall make reasonably available
for inspection by Purchaser,  any underwriter  participating  in any disposition

and other records,  pertinent  corporate documents and properties of the Company
and its subsidiaries,  and cause the Company's officers, directors and employees
to supply all  information  reasonably  requested  by the  Purchaser or any such
underwriter,  attorney,  accountant or agent in connection with the Registration
Statement, in each case, as is customary for similar due diligence examinations;
provided,  however,  that  all  records,  information  and  documents  that  are
designated  in  writing  by  the  Company,   in  good  faith,  as  confidential,
proprietary  or containing  any material  non-public  information  shall be kept
confidential by the Purchaser and any such underwriter,  attorney. accountant or
agent (pursuant to an appropriate  confidentiality  agreement in the case of the

limit the scope of the information sought to be disclosed) or is required by law
or such  records,  information  or  documents  become  available  to the  public
generally  or  through  a  third  party  not  in  violation  of an  accompanying
obligation  of  confidentiality;  and provided  further  that.  if the foregoing

any of the  securities  for  sale in such  states  as the  Purchaser  reasonably
designates and shall furnish indemnification in the manner provided in Section 6
hereof. However, the Company shall not be required to qualify in any state which
will require an escrow or other  restriction  relating to the Company and/or the
sellers,  or which will  require  the  Company to qualify to do business in such
state or require the Company to file  therein any general  consent to service of
process. The Company at its expense will supply the Purchaser with copies of the
Registration  Statement and the  prospectus  included  therein and other related
documents in such quantities as may be reasonably requested by the Purchaser.

            (d) The Company shall not be required by this Section 3 to include a
Purchaser's Securities in any Registration Statement which is to be filed if, in
the opinion of counsel for both the Purchaser  and the Company (or,  should they
not agree,  in the opinion of another  counsel  experienced  in  securities  law
matters  acceptable  to counsel for the  Purchaser and the Company) the proposed
offering or other transfer as to which such  registration is requested is exempt
from  applicable  federal  and state  securities  laws and  would  result in all
purchasers  or  transferees  obtaining  securities  which  are  not  "restricted
securities", as defined imRul~l44 under the Securities Act.

            (e) If at any time or from time to time after die effective  date of
the Registration Statement. the Company notifies the Purchaser in writing of the
existence of a Potential  Material Event (as defined in Section 3(0 below),  the
Purchaser  shall  not  offer or sell  any  Securities  or  engage  in any  other
transaction involving or relating to Securities,  from the time of the giving of
notice with respect to a Potential  Material Event until the Purchaser  receives
written  notice from the Company that such  Potential  Material Event either has
been disclosed to

                                       3
<PAGE>

the public or no longer  constitutes a Potential Material Event (the "Suspension
Period");  provided,  however,  that,  during any twelve month period during the
periods the Registration  Statement is required to be in effect,  if the Company
so  suspends  the right to such  holders  of  Securities  for more than ten (10)
Trading Days in the aggregate  during any periods  commencing on a Trading Day a
Draw Down Notice is deemed  delivered and ending ten (10) Trading Days following
the end of the corresponding Draw Down Pricing Period (the "Grace Period"), then
the Company  must  compensate  the  Purchaser  for any net decline in the market
value of the  Securities  held by Purchaser at the beginning of any portion of a
Suspension  Period  that  exceeds  the  Grace  Period  through  the  end of such
Suspension Period and any Suspension Periods thereafter during such twelve month
period.  Net decline shall be calculated as the  difference  between the highest
VWAP  during the  applicable  Suspension  Period end the VWAP at the end of such
Suspension  Period. If a Potential  Material Event shall occur prior to the date
the Registration  Statement is filed, then the Company's  obligation to file the
Registration Statement shall be delayed without penalty for not more than thirty
(30) calendar days.  The Company must give Purchaser  notice in writing at least
two (2) Trading Days prior to the first day of the blackout period, if lawful to
do so.

            (f) "Potential  Material Event" means any of the following:  (a) the
possession  by  the  Company  of  material  information  that  is not  ripe  for
disclosure in a registration statement, as determined in good faith by the Chief
Executive Officer or the Board of Directors of the Company or that disclosure of
such  information  in the  Registration  Statement~would  be  detrimental to the
business and affairs of the Company;  or (b) any material engagement or activity
by the  Company  which  would,  in the good  faith  determination  of the  Chief
Executive  Officer  or the  Board of  Directors  of the  Company,  be  adversely
affected  by  disclosure  in  a  registration  statement  at  such  time,  which
determination  shall be accompanied by a good faith  determination  by the Chief
Executive Officer or the Board of Directors of the Company that the Registration
Statement  would  be  materially   misleading   absent  the  inclusion  of  such
information.

            Section 4. Cooperation  with Company.  Purchaser will cooperate with
the Company in all respects in connection with this Agreement.  including timely
supplying  all  information  reasonably  requested  by the Company  (which shall

arise out of or are based upon the omission or alleged omission to state therein
a  material  fact  required  to be  stated  therein  or  necessary  to make  the

                                       6
<PAGE>

that any such loss, claim. dama2e or liability arises out of or is based upon an

amendment  or  supplement  thereto in reliance  upon,  and in  conformity  with,
written  information  furnished  to the  Company by the  Distributing  Purchaser

promulgated  thereunder) a copy of the prospectus contained in such Registration

obligated  to do so  under  the  Securities  Act or the  rules  and  regulations
promulgated  thereunder.  This  indemnity  agreement  will be in addition to any
liability which the Company may otherwise have.

            (b) Each  Distributing  Purchaser  agrees that it will indemnify and
hold harmless the Company, arid each officer, director of the Company or person,
if any,  who  controls  the Company  within the meaning of the  Securities  Act,

Section 6 of notice of the commencement of any action,  such  indemnified  party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 6, notify the indemnifying party of the commencement thereof;
but the  omission  so to notify  the  indemnifying  party will not  relieve  the
indemnifying party from any liability which it may have to any indemnified party
except to the extent of actual prejudice demonstrated by the indemnifying party.
In case any such  action  is  brought  against  any  indemnified  party,  and it
notifies the indemnifying  party of the commencement  thereof.  the indemnifying
party will be entitled to  participate  in, and, to the extent that it may wish,
jointly with any other indemnifying party similarly notified, assume the defense
thereof,  subject to the  provisions  herein  stated and after  notice  from the
indemnifying  party to such  indemnified  party of its election so to assume the
defense thereof, the indemnifying

                                       7
<PAGE>

party will not be liable to such indemnified  party under this Section 6 for any
legal or other  expenses  subsequently  incurred  by such  indemnified  party in
connection   with  the  defense   thereof   other  than   reasonable   costs  of
investigation,  unless the indemnifying party shall not pursue the action to its
final conclusion.  The indemnified party shall have the right to employ separate
counsel in any such action and to  participate in the defense  thereof,  but the
fees  and  expenses  of  such  counsel  shall  not  be at  the  expense  of  the
indemnifying  party if the  indemnifying  party has  assumed  the defense of the
action with counsel reasonably  satisfactory to the indemnified party;  provided
that if the  indemnified  party  is the  Distributing  Purchaser,  the  fees and
expenses of such counsel  shall be at the expense of the  indemnifying  party if

by the  indemnifying  party,  or (ii)  the  named  parties  to any  such  action
(including any impleaded  parties) include both the  Distributing  Purchaser and
the indemnifying party and the Distributing Purchaser shall have been advised by
such  counsel  that there may be one or more  legal  defenses  available  to the
indemnifying  party  different from or in conflict with any legal defenses which
may be available to the  Distributing  Purchaser (in which case the indemnifying
party  shall not have the right,  to assume the defense of such action on behalf
of  the  Distributing  Purchaser,   it  being  understood,   however,  that  the
indemnifying party shall, in connection with any one such action or separate but
substantially  similar ~ related actions in the same jurisdiction arising out of
the same general allegations or circumstances, be liable only for the reasonable
fees  and  expenses  of one  separate  firm of  attorneys  for the  Distributing
Purchaser,  which  firm  shall be  designated  in  writing  by the  Distributing
Purchaser  and be approved by the  indemnifying  party).  No  settlement  of any
action  against an  indemnified  party shall be made  without the prior  written
consent  of the  indemnified  party,  which  consent  shall not be  unreasonably
withheld.

            All fees and expenses of the indemnified party (including reasonable
costs of  defense  and  investigation  in a manner  not  inconsistent  with this
Section and all reasonable  attorneys'  fees arid expenses) shall be paid to the
indemnified  party, as incurred,  within ten (10) Trading Days of written notice
thereof to the indemnifying party; provided,  that the i~ide7xnnifying party may
require such  indemnified  party to  undertake  to  reimburse  all such fees and
expenses to the extent it is finally judicially determined that such indemnified
party is not entitled to indemnification hereunder).

            Section 7. Contribution.  In order to provide for just and equitable
contribution  under the Securities Act in any case in which (i) the  indemnified
party  makes a claim for  indemnification  pursuant  to  Section 6 hereof but is
judicially  determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that the express provisions of Section 6 hereof provide
for  indemnification in such case, or (ii) contribution under the Securities Act
may be required on the part of any indemnified  party,  then the Company and the
applicable  Distributing  Purchaser  shall  contribute to the aggregate  losses,
claims,  damages or liabilities  to which they may be subject (which shall,  for
all purposes of this Agreement,  include,  hut not be limited to, all reasonable
