        WHEREAS,  the  Company  has  filed  with  the  Securities  and  Exchange

        NOW,  THEREFORE,  in  consideration  of  the  mutual  agreements  herein
contained, the parties hereto agree as follows:

<PAGE>

1.      APPOINTMENT  OF WARRANT AGENT.  The Company hereby  appoints the Warrant
Agent to act as agent for the Company for the  Warrants,  and the Warrant  Agent
hereby  accepts such  appointment  and agrees to perform the same in  accordance
with the terms and conditions set forth in this Agreement.

2.      WARRANTS.

        2.1     FORM OF WARRANT. Each Public Warrant and Underwriters'  Warrants
shall be issued in registered form only, shall be in substantially  the forms of
Exhibit A and  Exhibit  B  hereto,  respectively,  the  provisions  of which are
incorporated  herein and shall be signed by, or bear the facsimile signature of,
the Chairman of the Board or Chief Executive Officer and Treasurer, Secretary or
Assistant  Secretary of the Company and shall bear a facsimile of the  Company's
seal. In the event the person whose facsimile signature has been placed upon any
Warrant  shall have ceased to serve in the capacity in which such person  signed
the Warrant before such Warrant is issued, it may be issued with the same effect
as if he or she had not ceased to be such at the date of issuance.

        2.2     EFFECT OF  COUNTERSIGNATURE.  Unless and until  countersigned by
the Warrant Agent pursuant to this Agreement,  a Warrant shall be invalid and of
no effect and may not be exercised by the holder thereof.

        2.3     REGISTRATION.

                2.3.1   WARRANT REGISTER. The Warrant Agent shall maintain books
("Warrant   Register")  for  the  registration  of  original  issuance  and  the
registration  of transfer  of the  Warrants.  Upon the  initial  issuance of the
Warrants,  the Warrant  Agent shall issue and register the Warrants in the names
of the  respective  holders  thereof  in such  denominations  and  otherwise  in
accordance with instructions delivered to the Warrant Agent by the Company.

                2.3.2   REGISTERED   HOLDER.   Prior  to  due   presentment  for
registration  of transfer of any Warrant,  the Company and the Warrant Agent may
deem and treat the person in whose name such Warrant  shall be  registered  upon
the  Warrant  Register  ("registered  holder"),  as the  absolute  owner of such
Warrant and of each Warrant represented thereby (notwithstanding any notation of
ownership or other writing on the Warrant  Certificate made by anyone other than
the Company or the Warrant Agent), for the purpose of any exercise thereof,  and
for all other  purposes,  and neither the Company nor the Warrant Agent shall be
affected by any notice to the contrary.

        2.4     DETACHABILITY OF WARRANTS.  The securities  comprising the Units
will not be separately  transferable until 20 trading days following the earlier
to  occur of the  expiration  to occur  of the  expiration  of Jesup &  Lamont's
over-allotment  option or its exercise in full unless Jesup & Lamont informs the
Company of its decision to allow earlier separate trading,  but in no event will
Jesup & Lamont allow  separate  trading of the  securities  comprising the Units
until the Company files a Current  Report on Form 8-K, which includes an audited
balance sheet reflecting the receipt by the Company of the gross proceeds of the
Public Offering including the proceeds

                                       2
<PAGE>

received by the Company  from the exercise of the  Underwriter's  over-allotment
option,  if the  over-allotment  option is exercised  prior to the filing of the
Form 8-K.

        2.5     PUBLIC  WARRANTS  AND  UNDERWRITERS'  WARRANTS.  Except  for the
exercise price, the  Underwriters'  Warrants shall have the same terms and be in
the same form as the Public Warrants.

3.      TERMS AND EXERCISE OF WARRANTS.

        3.1     WARRANT PRICE. Each Public Warrant shall, when  countersigned by
the  Warrant  Agent,  entitle  the  registered  holder  thereof,  subject to the
provisions  of such Public  Warrant and of this Warrant  Agreement,  to purchase
from the Company the number of shares of Common  Stock  stated  therein,  at the
price of $5.00 per whole share, subject to the adjustments provided in Section 4
hereof and in the last sentence of this Section 3.1. Each Underwriters'  Warrant
shall,  when  countersigned by the Warrant Agent,  entitle the registered holder
thereof,  subject to the  provisions of such  Underwriters'  Warrant and of this
Warrant  Agreement,  to purchase from the Company the number of shares of Common
Stock  stated  therein,  at the price of $6.25 per whole  share,  subject to the
adjustments  provided  in  Section  4 hereof  and in the last  sentence  of this
Section 3.1. The term "Warrant Price" as used in this Warrant  Agreement  refers
to the price  per share at which  Common  Stock may be  purchased  at the time a
Warrant is exercised.  The Company in its sole  discretion may lower the Warrant
Price at any time prior to the Expiration Date; provided that any such reduction
shall be identical in percentage terms among all of the Warrants.

        3.2     DURATION OF WARRANTS. A Warrant may be exercised only during the
period  ("Exercise  Period")  commencing on the later of the consummation by the
Company of a merger, capital stock exchange,  asset acquisition or other similar
business  combination  ("Business  Combination") (as described more fully in the
Company's  Registration  Statement) or _________ ___,  2006, and  terminating at
5:00 p.m.,  New York City time on the earlier to occur of (i) ________ ___, 2009
or (ii) the date fixed for  redemption  of the Warrants as provided in Section 6
of this  Agreement  ("Expiration  Date").  Except  with  respect to the right to
receive the Redemption Price (as set forth in Section 6 hereunder), each Warrant
not exercised on or before the Expiration Date shall become void, and all rights
thereunder and all rights in respect thereof under this Agreement shall cease at
the close of business on the Expiration Date. The Company in its sole discretion
may extend the  duration  of the  Warrants  by  delaying  the  Expiration  Date;
provided that any such extension shall be identical in duration among all of the
Warrants.

        3.3     EXERCISE OF WARRANTS.

                3.3.1   PAYMENT.  Subject to the  provisions  of the Warrant and
this Warrant Agreement,  a Warrant, when countersigned by the Warrant Agent, may
be exercised by the registered  holder thereof by surrendering it, at the office
of the Warrant Agent, or at the office of its successor as Warrant Agent, in the
Borough of Manhattan, City and State of New York, with the subscription form, as
set forth in the Warrant, duly executed,  and by paying in full, in lawful money
of the United States,  in cash,  good certified check or good bank draft payable
to the order of the  Company,  the  Warrant  Price for each full share of Common
Stock as to which the Warrant

                                       3
<PAGE>

is  exercised  and any and all  applicable  taxes  due in  connection  with  the
exercise of the Warrant,  the exchange of the Warrant for the Common Stock,  and
the issuance of the Common Stock.

                3.3.2   ISSUANCE OF CERTIFICATES.  As soon as practicable  after
the  exercise of any Warrant  and the  clearance  of the funds in payment of the
Warrant Price, the Company shall issue to the registered  holder of such Warrant
a certificate or  certificates  for the number of full shares of Common Stock to
which he is  entitled,  registered  in such name or names as may be  directed by
him,  and if  such  Warrant  shall  not  have  been  exercised  in  full,  a new
countersigned  Warrant for the number of shares as to which such  Warrant  shall
not have been exercised. Notwithstanding the foregoing, the Company shall not be
obligated to deliver any securities pursuant to the exercise of a Warrant unless
(i) a registration  statement  under the Act with respect to the Common Stock is
effective or (ii) in the opinion of counsel to the Company,  the exercise of the
Warrants  is  exempt  from  the  registration  requirements  of the Act and such
securities are qualified for sale or exempt from qualification  under applicable
securities  laws of the states or other  jurisdictions  in which the  registered
holders reside.  Warrants may not be exercised by, or securities  issued to, any
registered holder in any state in which such exercise would be unlawful.

                3.3.3   VALID  ISSUANCE.  All shares of Common Stock issued upon
the proper  exercise of a Warrant in  conformity  with this  Agreement  shall be
validly issued, fully paid and nonassessable.

                3.3.4   DATE OF  ISSUANCE.  Each  person in whose  name any such
certificate  for  shares of Common  Stock is issued  shall for all  purposes  be
deemed to have  become the holder of record of such  shares on the date on which
the  Warrant  was  surrendered  and  payment  of the  Warrant  Price  was  made,
irrespective  of the date of delivery of such  certificate,  except that, if the
date of such  surrender and payment is a date when the stock  transfer  books of
the Company are closed, such person shall be deemed to have become the holder of
such shares at the close of business  on the next  succeeding  date on which the
stock transfer books are open.

4.      ADJUSTMENTS.

        4.1     STOCK DIVIDENDS SPLIT UPS. If after the date hereof, and subject
to the  provisions  of Section 4.6, the number of  outstanding  shares of Common
Stock is increased by a stock dividend  payable in shares of Common Stock, or by
a split up of shares of Common  Stock,  or other  similar  event,  then,  on the
effective date of such stock dividend,  split up or similar event, the number of
shares  issuable on exercise of each Warrant shall be increased in proportion to
such increase in outstanding shares.

        4.2     AGGREGATION OF SHARES. If after the date hereof,  and subject to
the provisions of Section 4.6, the number of outstanding  shares of Common Stock
is  decreased  by  a   consolidation,   combination,   reverse  stock  split  or
reclassification  of shares of Common Stock or other similar event, then, on the
effective  date  of  such  consolidation,   combination,  reverse  stock  split,
reclassification  or similar event, the number of shares issuable on exercise of
each Warrant shall be decreased in  proportion  to such decrease in  outstanding
shares.

                                       4
<PAGE>

        4.3     ADJUSTMENTS IN EXERCISE PRICE.  Whenever the number of shares of
Common Stock  purchasable  upon the  exercise of the  Warrants is  adjusted,  as
provided in Section 4.1 and 4.2 above,  the Warrant  Price shall be adjusted (to
the nearest cent) by multiplying  such Warrant Price  immediately  prior to such
adjustment  by a  fraction  (x) the  numerator  of which  shall be the number of
shares of Common Stock purchasable upon the exercise of the Warrants immediately
prior to such  adjustment,  and (y) the denominator of which shall be the number
of shares of Common Stock so purchasable immediately thereafter.

        4.4     REPLACEMENT OF SECURITIES UPON  REORGANIZATION,  ETC. In case of
any reclassification or reorganization of the outstanding shares of Common Stock
(other than a change covered by Section 4.1 or 4.2 hereof or that solely affects
the par value of such shares of Common  Stock),  or in the case of any merger or
consolidation  of the Company  with or into  another  corporation  (other than a
consolidation  or merger in which the Company is the continuing  corporation and
that  does  not  result  in  any   reclassification  or  reorganization  of  the
outstanding shares of Common Stock), or in the case of any sale or conveyance to
another  corporation or entity of the assets or other property of the Company as
an entirety or substantially as an entirety in connection with which the Company
is dissolved,  the Warrant  holders shall  thereafter have the right to purchase
and receive,  upon the basis and upon the terms and conditions  specified in the
Warrants  and in lieu of the shares of Common  Stock of the Company  immediately
theretofore   purchasable  and  receivable  upon  the  exercise  of  the  rights
represented  thereby, the kind and amount of shares of stock or other securities
or   property   (including   cash)   receivable   upon  such   reclassification,
reorganization,  merger or  consolidation,  or upon a dissolution  following any
such sale or  transfer,  by a Warrant  holder of the  number of shares of Common
Stock of the Company obtainable upon exercise of the Warrants  immediately prior
to such event; and if any reclassification also results in a change in shares of
Common Stock covered by Section 4.1 or 4.2, then such  adjustment  shall be made
pursuant to Sections 4.1, 4.2, 4.3 and this Section 4.4. The  provisions of this
Section   4.4   shall   similarly   apply   to   successive   reclassifications,
reorganizations, mergers or consolidations, sales or other transfers.

        4.5     NOTICES OF  CHANGES IN  WARRANT.  Upon every  adjustment  of the
Warrant  Price or the number of shares  issuable on  exercise of a Warrant,  the
Company shall give written  notice  thereof to the Warrant  Agent,  which notice
shall state the Warrant Price resulting from such adjustment and the increase or
decrease,  if any,  in the number of shares  purchasable  at such price upon the
exercise  of a  Warrant,  setting  forth in  reasonable  detail  the  method  of
calculation  and the facts  upon  which  such  calculation  is  based.  Upon the
occurrence of any event specified in Sections 4.1, 4.2, 4.3 or 4.4, then, in any
such event, the Company shall give written notice to the Warrant holder,  at the
last  address set forth for such holder in the warrant  register,  of the record
date or the  effective  date of the event.  Failure to give such notice,  or any
defect therein, shall not affect the legality or validity of such event.

        4.6     NO FRACTIONAL SHARES. Notwithstanding any provision contained in
this Warrant  Agreement to the contrary,  the Company shall not issue fractional
shares upon exercise of Warrants.  If, by reason of any adjustment made pursuant
to this  Section  4, the  holder  of any  Warrant  would be  entitled,  upon the
exercise of such  Warrant,  to receive a  fractional  interest  in a share,  the
Company  shall,  upon such  exercise,  round up to the nearest  whole number the
number of the shares of Common Stock to be issued to the Warrant holder.

                                       5
<PAGE>

        4.7     FORM OF WARRANT.  The forms of Public Warrant and  Underwriters'
Warrant need not be changed  because of any adjustment  pursuant to this Section
4, and Warrants  issued after such  adjustment  may state the same Warrant Price
and the same  number of shares as is  stated in the  Warrants  initially  issued
pursuant  to this  Agreement.  However,  the Company may at any time in its sole
discretion  make any change in the form of  Warrant  that the  Company  may deem
appropriate  and that does not affect the  substance  thereof,  and any  Warrant
thereafter issued or  countersigned,  whether in exchange or substitution for an
outstanding Warrant or otherwise, may be in the form as so changed.

        4.8     NOTICE OF CERTAIN  TRANSACTIONS.  In the event that the  Company
shall  propose to (a) offer the holders of its Common  Stock rights to subscribe
for or to purchase  any  securities  convertible  into shares of Common Stock or
shares of stock of any class or any other  securities,  rights or  options,  (b)
issue any rights,  options or warrants  entitling the holders of Common Stock to
subscribe  for  shares of Common  Stock or (c) make a tender  offer or  exchange
offer with respect to the Common  Stock,  the Company  shall send to the Warrant
holders a notice of such proposed  action or offer.  Such notice shall be mailed
to the  registered  holders at their  addresses  as they  appear in the  Warrant
Register, which shall specify the record date for the purposes of such dividend,
distribution or rights,  or the date such issuance or event is to take place and
the date of  participation  therein by the holders of Common Stock,  if any such
date is to be fixed, and shall briefly indicate the effect of such action on the
Common  Stock and on the  number  and kind of any  other  shares of stock and on
other  property,  if any,  and the  number of  shares of Common  Stock and other
property,  if any,  issuable upon exercise of each Warrant and the Warrant Price
after giving effect to any adjustment  pursuant to this Article 4 which would be
required as a result of such  action.  Such notice shall be given as promptly as
practicable  after the Board of  Directors  of the  Company  (the  "Board")  has
determined to take any such action and (x) in the case of any action  covered by
clause  (a) or (b)  above  at  least  10  days  prior  to the  record  date  for
determining  the holders of the Common  Stock for purposes of such action or (y)
in the case of any other  such  action at least 20 days prior to the date of the
taking of such  proposed  action  or the date of  participation  therein  by the
holders of Common Stock, whichever shall be the earlier.

        4.9     OTHER  EVENTS.  If any event  occurs  as to which the  foregoing
provisions  of this  Article  4 are not  strictly  applicable  or,  if  strictly
applicable,  would not,  in the good  faith  judgment  of the Board,  fairly and
adequately protect the purchase rights of the registered holders of the Warrants
in accordance with the essential intent and principles of such provisions,  then
the Board shall make such adjustments in the application of such provisions,  in
accordance  with such essential  intent and  principles,  as shall be reasonably
necessary,  in the good faith  opinion of the Board,  to protect  such  purchase
rights as aforesaid.

5.      TRANSFER AND EXCHANGE OF WARRANTS.

        5.1     REGISTRATION  OF TRANSFER.  The Warrant Agent shall register the
transfer,  from  time to time,  of any  outstanding  Warrant  upon  the  Warrant
Register,  upon surrender of such Warrant for transfer,  properly  endorsed with
signatures properly  guaranteed and accompanied by appropriate  instructions for
transfer.  Upon any such transfer, a new Warrant representing an equal aggregate
number of Warrants shall be issued and the old Warrant shall be cancelled by the
Warrant Agent. The Warrants so cancelled shall be delivered by the Warrant Agent
to the Company from time to time upon request.

                                       6
<PAGE>

        5.2     PROCEDURE FOR SURRENDER OF WARRANTS. Warrants may be surrendered
to the Warrant Agent,  together with a written request for exchange or transfer,
and thereupon the Warrant Agent shall issue in exchange therefor one or more new
Warrants as requested by the registered  holder of the Warrants so  surrendered,
representing an equal aggregate number of Warrants;  provided,  however, that in
the event that a Warrant  surrendered  for transfer bears a restrictive  legend,
the  Warrant  Agent  shall not cancel  such  Warrant  and issue new  Warrants in
exchange therefor until the Warrant Agent has received an opinion of counsel for
the Company  stating that such transfer may be made and  indicating  whether the
new Warrants must also bear a restrictive legend.

        5.3     FRACTIONAL WARRANTS.  The Warrant Agent shall not be required to
effect any  registration  of  transfer  or  exchange  which  will  result in the
issuance of a warrant certificate for a fraction of a warrant.

        5.4     SERVICE  CHARGES.  No  service  charge  shall  be  made  for any
exchange or registration of transfer of Warrants.

        5.5     WARRANT  EXECUTION  AND  COUNTERSIGNATURE.  The Warrant Agent is
hereby authorized to countersign and to deliver, in accordance with the terms of
this Agreement, the Warrants required to be issued pursuant to the provisions of
this Section 5, and the Company,  whenever  required by the Warrant Agent,  will
supply the Warrant  Agent with  Warrants  duly executed on behalf of the Company
for such purpose.

6.      REDEMPTION.

        6.1     REDEMPTION.  Subject to Section 6.4 hereof, not less than all of
the outstanding  Warrants may be redeemed,  at the option of the Company, at any
time after they become exercisable and prior to their expiration,  at the office
of the Warrant Agent,  upon the notice  referred to in Section 6.2, at the price
of $.01 per Warrant ("Redemption Price"),  provided that the last sales price of
the Common Stock has been equal to or greater  than $8.50 per share,  on each of
twenty (20) trading days within any thirty (30) trading day period ending on the
third business day prior to the date on which notice of redemption is given. The
provisions of this Section 6.1 may not be modified,  amended or deleted  without
the prior written consent of Jesup & Lamont.

        6.2     DATE FIXED FOR,  AND  NOTICE  OF,  REDEMPTION.  In the event the
Company shall elect to redeem all of the Warrants,  the Company shall fix a date
for the  redemption.  Notice of redemption  shall be mailed by first class mail,
postage  prepaid,  by the  Company not less than 30 days prior to the date fixed
for redemption to the registered holders of the Warrants to be redeemed at their
last addresses as they shall appear on the registration books. Any notice mailed
in the manner herein provided shall be  conclusively  presumed to have been duly
given whether or not the registered holder received such notice.

        6.3     EXERCISE  AFTER  NOTICE  OF  REDEMPTION.  The  Warrants  may  be
exercised  in  accordance  with  Section 3 of this  Agreement  at any time after
notice of  redemption  shall have been given by the Company  pursuant to Section
6.2 hereof and prior to the time and date fixed

                                       7
<PAGE>

for  redemption.  On and after the  redemption  date,  the record  holder of the
Warrants shall have no further  rights except to receive,  upon surrender of the
Warrants, the Redemption Price.

        6.4     OUTSTANDING  WARRANTS  ONLY.  The Company  understands  that the
redemption  rights  provided  for by this  Section 6 apply  only to  outstanding
Warrants.  To the  extent a person  holds  rights  to  purchase  Warrants,  such
purchase  rights shall not be  extinguished  by redemption.  However,  once such
purchase  rights are exercised,  the Company may redeem the Warrants issued upon
such exercise  provided that the criteria for  redemption is met,  including the
opportunity of the Warrant  holder to exercise  prior to redemption  pursuant to
Section 6.3. The provisions of this Section 6.4 may not be modified,  amended or
deleted without the prior written consent of Jesup & Lamont.

7.      OTHER PROVISIONS RELATING TO RIGHTS OF HOLDERS OF WARRANTS.

        7.1     NO  RIGHTS  AS  STOCKHOLDER.  A  Warrant  does not  entitle  the
registered  holder thereof to any of the rights of a stockholder of the Company,
including,  without  limitation,  the  right  to  receive  dividends,  or  other
distributions,  exercise  any  preemptive  rights  to vote or to  consent  or to
receive notice as stockholders in respect of the meetings of stockholders or the
election of directors of the Company or any other matter.

        7.2     LOST, STOLEN,  MUTILATED,  OR DESTROYED WARRANTS. If any Warrant
is lost, stolen,  mutilated, or destroyed, the Company and the Warrant Agent may
on such  terms as to  indemnity  or  otherwise  as they may in their  discretion
impose (which shall, in the case of a mutilated  Warrant,  include the surrender
thereof),  issue a new  Warrant  of like  denomination,  tenor,  and date as the
Warrant so lost,  stolen,  mutilated,  or destroyed.  Any such new Warrant shall
constitute a substitute  contractual  obligation of the Company,  whether or not
the allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time
enforceable by anyone.

        7.3     RESERVATION  OF COMMON  STOCK.  The  Company  shall at all times
reserve and keep  available a number of its  authorized  but unissued  shares of
Common  Stock  that will be  sufficient  to permit the  exercise  in full of all
outstanding Warrants issued pursuant to this Agreement.

        7.4     REGISTRATION  OF COMMON STOCK.  The Company agrees that prior to
the commencement of the Exercise  Period,  it shall file with the Securities and
Exchange Commission a post-effective amendment to the Registration Statement, or
a new registration  statement,  for the registration,  under the Act, of, and it
shall take such action as is necessary  to qualify for sale,  in those states in
which the  Warrants  were  initially  offered by the  Company,  the Common Stock
issuable upon exercise of the Warrants. In either case, the Company will use its
best  efforts  to  cause  the  same  to  become  effective  on or  prior  to the
commencement  of the Exercise Period and to maintain the  effectiveness  of such
registration   statement  until  the  expiration  of  the  Public  Warrants  and
Underwriters' Warrants in accordance with the provisions of this Agreement.  The
provisions of this Section 7.4 may not be modified,  amended or deleted  without
the prior written consent of Jesup & Lamont.

8.      CONCERNING THE WARRANT AGENT AND OTHER MATTERS.

        8.1     PAYMENT OF TAXES.  The Company  will from time to time  promptly
pay all taxes and  charges  that may be imposed  upon the Company or the Warrant
Agent in respect of the

                                       8
<PAGE>

issuance or delivery of shares of Common  Stock upon the  exercise of  Warrants,
but the Company  shall not be obligated to pay any transfer  taxes in respect of

        8.2     RESIGNATION, CONSOLIDATION, OR MERGER OF WARRANT AGENT.

                8.2.1   APPOINTMENT  OF  SUCCESSOR  WARRANT  AGENT.  The Warrant
Agent, or any successor to it hereafter appointed,  may resign its duties and be
discharged from all further duties and liabilities  hereunder after giving sixty
(60) days' notice in writing to the Company.  If the office of the Warrant Agent
becomes  vacant by  resignation  or incapacity to act or otherwise,  the Company
shall  appoint  in writing a  successor  Warrant  Agent in place of the  Warrant
Agent. If the Company shall fail to make such appointment  within a period of 30
days after it has been notified in writing of such  resignation or incapacity by
the Warrant Agent or by the holder of the Warrant (who shall,  with such notice,
submit  his  Warrant  for  inspection  by the  Company),  then the holder of any
Warrant may apply to the  Supreme  Court of the State of New York for the County
of New York for the  appointment  of a successor  Warrant  Agent.  Any successor
Warrant  Agent,  whether  appointed by the Company or by such court,  shall be a
corporation  organized and existing  under the laws of the State of New York, in
good standing and having its principal office in the Borough of Manhattan,  City
and State of New York,  and  authorized  under such laws to  exercise  corporate
trust  powers and  subject to  supervision  or  examination  by federal or state
authority.  After appointment,  any successor Warrant Agent shall be vested with
all the authority,  powers, rights,  immunities,  duties, and obligations of its
predecessor  Warrant  Agent with like effect as if  originally  named as Warrant
Agent  hereunder,  without  any  further  act or deed;  but if for any reason it
becomes  necessary or appropriate,  the predecessor  Warrant Agent shall execute
and deliver, at the expense of the Company,  an instrument  transferring to such
successor  Warrant  Agent  all  the  authority,   powers,  and  rights  of  such
predecessor  Warrant Agent hereunder;  and upon request of any successor Warrant
Agent the Company  shall  make,  execute,  acknowledge,  and deliver any and all
instruments in writing for more fully and effectually  vesting in and confirming
to such successor Warrant Agent all such authority,  powers, rights, immunities,
duties, and obligations.

                8.2.2   NOTICE  OF  SUCCESSOR  WARRANT  AGENT.  In the  event  a
successor  Warrant  Agent  shall be  appointed,  the  Company  shall give notice
thereof to the  predecessor  Warrant Agent and the transfer agent for the Common
Stock not later than the effective date of any such appointment.

                8.2.3   MERGER  OR   CONSOLIDATION   OF   WARRANT   AGENT.   Any
corporation  into which the Warrant  Agent may be merged or with which it may be
consolidated or any corporation  resulting from any merger or  consolidation  to
which the Warrant  Agent shall be a party shall be the  successor  Warrant Agent
under this Agreement without any further act.

        8.3     FEES AND EXPENSES OF WARRANT AGENT.

                8.3.1   REMUNERATION.  The  Company  agrees  to pay the  Warrant
Agent  reasonable  remuneration for its services as such Warrant Agent hereunder
and will reimburse the Warrant Agent upon demand for all  expenditures  that the
Warrant Agent may reasonably incur in the execution of its duties hereunder.

                8.3.2   FURTHER  ASSURANCES.  The  Company  agrees  to  perform,
execute,   acknowledge,  and  deliver  or  cause  to  be  performed,   executed,
acknowledged,  and delivered all such further and other acts,  instruments,  and
assurances  as may  reasonably be required by the Warrant Agent for the carrying
out or performing of the provisions of this Agreement.

        8.4     LIABILITY OF WARRANT AGENT.

                8.4.1   RELIANCE   ON  COMPANY   STATEMENT.   Whenever   in  the
performance of its duties under this Warrant Agreement,  the Warrant Agent shall
deem it necessary or desirable  that any fact or matter be proved or established
by the Company prior to taking or suffering any action  hereunder,  such fact or
matter  (unless  other  evidence  in  respect  thereof  be  herein  specifically
prescribed)  may be  deemed  to be  conclusively  proved  and  established  by a
statement  signed by the  President  or Chairman of the Board of the Company and
delivered to the Warrant  Agent.  The Warrant Agent may rely upon such statement
for any action taken or suffered in good faith by it pursuant to the  provisions
of this Agreement.

                8.4.2   INDEMNITY.  The Warrant Agent shall be liable  hereunder
only for its own negligence, willful misconduct or bad faith. The Company agrees
to  indemnify  the  Warrant  Agent  and  save it  harmless  against  any and all
liabilities,  including  judgments,  costs  and  reasonable  counsel  fees,  for
anything done or omitted by the Warrant Agent in the execution of this Agreement
except as a result of the Warrant Agent's negligence, willful misconduct, or bad
faith.

                8.4.3   EXCLUSIONS.    The   Warrant   Agent   shall   have   no
responsibility with respect to the validity of this Agreement or with respect to
the validity or execution of any Warrant (except its countersignature  thereof);
nor shall it be  responsible  for any breach by the  Company of any  covenant or
condition  contained  in this  Agreement  or in any  Warrant;  nor  shall  it be
responsible to make any  adjustments  required under the provisions of Section 4
hereof or responsible for the manner,  method,  or amount of any such adjustment
or the  ascertaining  of the  existence  of facts  that would  require  any such
adjustment;   nor  shall  it  by  any  act  hereunder  be  deemed  to  make  any
representation  or warranty as to the authorization or reservation of any shares
of Common Stock to be issued  pursuant to this Agreement or any Warrant or as to
whether any shares of Common  Stock will when issued be valid and fully paid and
nonassessable.

        8.5     ACCEPTANCE  OF AGENCY.  The  Warrant  Agent  hereby  accepts the
agency  established  by this  Agreement  and agrees to perform the same upon the
terms and  conditions  herein set forth and among other  things,  shall  account
promptly to the Company  with  respect to Warrants  exercised  and  concurrently
account for, and pay to the Company,  all moneys  received by the Warrant  Agent
for the purchase of shares of the Company's Common Stock through the exercise of
Warrants.

      SECTION 2.2 FORM OF SECURITIES AND TRUSTEE'S CERTIFICATE.

      The Securities of any series and the Trustee's certificate of

tenor and purport as set forth in one or more indentures supplemental hereto or
as provided in a Board Resolution, and set forth in an Officers' Certificate,
and they may have such letters, numbers or other marks of identification or
designation and such legends or endorsements printed, lithographed or engraved
thereon as the Company may deem appropriate and as are not inconsistent with the
provisions of this Indenture, or as may be required to comply with any law or
with any rule or regulation made pursuant thereto or with any rule or regulation
of any securities exchange on which Securities of that series may be listed, or
to conform to usage.

      SECTION 2.3 DENOMINATIONS: PROVISIONS FOR PAYMENT.

      The Securities shall be issuable as registered Securities and in the
denominations of one thousand U.S. dollars ($1,000) or any integral multiple
thereof, subject to Section 2.1(10). The Securities of a particular series shall
bear interest payable on the dates and at the rate specified with respect to
that series. The principal of and the interest on the Securities of any series,
as well as any premium thereon in case of redemption thereof prior to maturity,
shall be payable in the coin or currency of the United States of America that at
the time is legal tender for public and private debt, at the office or agency of
the Company maintained for that purpose in the Borough of Manhattan, the City
and State of New York. Each Security shall be dated the date of its
authentication. Interest on the Securities shall be computed on the basis of a
360-day year composed of twelve 30-day months.

      The interest installment on any Security that is payable, and is
punctually paid or duly provided for, on any Interest Payment Date for
Securities of that series shall be paid to the Person in whose name said
Security (or one or more Predecessor Securities) is registered at the

                                       7
<PAGE>

close of business on the regular record date for such interest installment. In
the event that any Security of a particular series or portion thereof is called
for redemption and the redemption date is subsequent to a regular record date
with respect to any Interest Payment Date and prior to such Interest Payment
Date, interest on such Security will be paid upon presentation and surrender of
such Security as provided in Section 3.3.

      Any interest on any Security that is payable, but is not punctually paid
or duly provided for, on any Interest Payment Date for Securities of the same
series (herein called "Defaulted Interest") shall forthwith cease to be payable
to the registered holder on the relevant regular record date by virtue of having
been such holder; and such Defaulted Interest shall be paid by the Company, at
its election, as provided in clause (1) or clause (2) below:

            (1) The Company may make payment of any Defaulted Interest on
      Securities to the Persons in whose names such Securities (or their
      respective Predecessor Securities) are registered at the close of business
      on a special record date for the payment of such Defaulted Interest, which
      shall be fixed in the following manner: the Company shall notify the
      Trustee in writing of the amount of Defaulted Interest proposed to be paid
      on each such Security and the date of the proposed payment, and at the
      same time the Company shall deposit with the Trustee an amount of money
      equal to the aggregate amount proposed to be paid in respect of such
      Defaulted Interest or shall make arrangements satisfactory to the Trustee
      for such deposit prior to the date of the proposed payment, such money
      when deposited to be held in trust for the benefit of the Persons entitled
      to such Defaulted Interest as in this clause provided. Thereupon the
      Trustee shall fix a special record date for the payment of such Defaulted
      Interest which shall not be more than 15 nor less than 10 days prior to
      the date of the proposed payment and not less than 10 days after the
      receipt by the Trustee of the notice of the proposed payment. The Trustee
      shall promptly notify the Company of such special record date and, in the
      name and at the expense of the Company, shall cause notice of the proposed
      payment of such Defaulted Interest and the special record date therefor to
      be mailed, first class postage prepaid, to each Securityholder at his or
      her address as it appears in the Security Register (as hereinafter
      defined), not less than 10 days prior to such special record date. Notice
      of the proposed payment of such Defaulted Interest and the special record
      date therefor having been mailed as aforesaid, such Defaulted Interest
      shall be paid to the Persons in whose names such Securities (or their
      respective Predecessor Securities) are registered on such special record
      date.

            (2) The Company may make payment of any Defaulted Interest on any
      Securities in any other lawful manner not inconsistent with the
      requirements of any securities exchange on which such Securities may be
      listed, and upon such notice as may be required by such exchange, if,
      after notice given by the Company to the Trustee of the proposed payment
      pursuant to this clause, such manner of payment shall be deemed
      practicable by the Trustee.

      Unless otherwise set forth in a Board Resolution or one or more indentures
supplemental hereto establishing the terms of any series of Securities pursuant
to Section 2.1 hereof, the term "regular record date" as used in this Section
with respect to a series of Securities and any Interest Payment Date for such
series shall mean either the fifteenth day of the month immediately

                                       8
<PAGE>

preceding the month in which an Interest Payment Date established for such
series pursuant to Section 2.1 hereof shall occur, if such Interest Payment Date
is the first day of a month, or the last day of the month immediately preceding
the month in which an Interest Payment Date established for such series pursuant
to Section 2.1 hereof shall occur, if such Interest Payment Date is the
fifteenth day of a month, whether or not such date is a Business Day.

      Subject to the foregoing provisions of this Section, each Security of a
series delivered under this Indenture upon transfer of or in exchange for or in
lieu of any other Security of such series shall carry the rights to interest
accrued and unpaid, and to accrue, that were carried by such other Security.

ceased to be such an officer of the Company. The seal of the Company may be in
the form of a facsimile of such seal and may be impressed, affixed, imprinted or
otherwise reproduced on the Securities. The Securities may contain such
notations, legends or endorsements required by law, stock exchange rule or
usage. Each Security shall be dated the date of its authentication by the
Trustee.

      A Security shall not be valid until authenticated manually by an
authorized signatory of the Trustee, or by an Authenticating Agent. Such
signature shall be conclusive evidence that the Security so authenticated has
been duly authenticated and delivered hereunder and that the holder is entitled
to the benefits of this Indenture. At any time and from time to time after the
execution and delivery of this Indenture, the Company may deliver Securities of
any series executed by the Company to the Trustee for authentication, together
with a written order of the Company for the authentication and delivery of such
Securities, signed by a chief executive officer, president, senior vice
president or any vice president, chief financial officer, chief legal officer,
treasurer or assistant treasurer, controller or assistant controller, and its
secretary or any assistant secretary, and the Trustee in accordance with such
written order shall authenticate and deliver such Securities.

      In authenticating such Securities and accepting the additional
responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, and (subject to Section 7.1) shall be
fully protected in relying upon, an Opinion of Counsel stating that the form and
terms thereof have been established in conformity with the provisions of this
Indenture.

                                       9
<PAGE>

      The Trustee shall not be required to authenticate such Securities if the
issue of such Securities pursuant to this Indenture will affect the Trustee's
own rights, duties or immunities under the Securities and this Indenture or
otherwise in a manner that is not reasonably acceptable to the Trustee.

      SECTION 2.5 REGISTRATION OF TRANSFER AND EXCHANGE.

      (a) Securities of any series may be exchanged upon presentation thereof at
the office or agency of the Company designated for such purpose in the Borough
of Manhattan, the City and State of New York, for other Securities of such
series of authorized denominations, and for a like aggregate principal amount,
upon payment of a sum sufficient to cover any tax or other governmental charge
in relation thereto, all as provided in this Section. In respect of any
Securities so surrendered for exchange, the Company shall execute, the Trustee
shall authenticate and such office or agency shall deliver in exchange therefore
the Security or Securities of the same series that the Securityholder making the
exchange shall be entitled to receive, bearing numbers not contemporaneously
outstanding.

      (b) The Company shall keep, or cause to be kept, at its office or agency
designated for such purpose in the Borough of Manhattan, the City and State of
New York, or such other location designated by the Company, a register or
registers (herein referred to as the "Security Register") in which, subject to
such reasonable regulations as it may prescribe, the Company shall register the
Securities and the transfers of Securities as in this Article provided and which
at all reasonable times shall be open for inspection by the Trustee. The
registrar for the purpose of registering Securities and transfer of Securities
as herein provided shall be appointed as authorized by Board Resolution (the
"Security Registrar").

      Upon surrender for transfer of any Security at the office or agency of the
Company designated for such purpose, the Company shall execute, the Trustee
shall authenticate and such office or agency shall deliver in the name of the
transferee or transferees a new Security or Securities of the same series as the
Security presented for a like aggregate principal amount.

      All Securities presented or surrendered for exchange or registration of
transfer, as provided in this Section, shall be accompanied (if so required by
the Company or the Security Registrar) by a written instrument or instruments of
transfer, in form satisfactory to the Company or the Security Registrar, duly
executed by the registered holder or by such holder's duly authorized attorney
in writing.

      (c) Except as provided pursuant to Section 2.1 pursuant to a Board
Resolution, and set forth in an Officers' Certificate, or established in one or
more indentures supplemental to this Indenture, no service charge shall be made
for any exchange or registration of transfer of Securities, or issue of new
Securities in case of partial redemption of any series, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge in relation thereto, other than exchanges pursuant to Section 2.6,
Section 3.3(b) and Section 9.4 not involving any transfer.

      (d) The Company shall not be required (i) to issue, exchange or register
the transfer of any Securities during a period beginning at the opening of
business 15 days before the day of the

                                       10
<PAGE>

mailing of a notice of redemption of less than all the Outstanding Securities of
the same series and ending at the close of business on the day of such mailing,
nor (ii) to register the transfer of or exchange any Securities of any series or
portions thereof called for redemption, other than the unredeemed portion of any
such Securities being redeemed in part. The provisions of this Section 2.5 are,
with respect to any Global Security, subject to Section 2.11 hereof.

      SECTION 2.6 TEMPORARY SECURITIES.

      Pending the preparation of definitive Securities of any series, the
Company may execute, and the Trustee shall authenticate and deliver, temporary
Securities (printed, lithographed or typewritten) of any authorized
denomination. Such temporary Securities shall be substantially in the form of
the definitive Securities in lieu of which they are issued, but with such
omissions, insertions and variations as may be appropriate for temporary
Securities, all as may be determined by the Company. Every temporary Security of
any series shall be executed by the Company and be authenticated by the Trustee
upon the same conditions and in substantially the same manner, and with like
effect, as the definitive Securities of such series. Without unnecessary delay
the Company will execute and will furnish definitive Securities of such series
and thereupon any or all temporary Securities of such series may be surrendered
in exchange therefor (without charge to the holders), at the office or agency of
the Company designated for the purpose in the Borough of Manhattan, the City and
State of New York, and the Trustee shall authenticate and such office or agency
shall deliver in exchange for such temporary Securities an equal aggregate
principal amount of definitive Securities of such series, unless the Company
advises the Trustee to the effect that definitive Securities need not be
executed and furnished until further notice from the Company. Until so
exchanged, the temporary Securities of such series shall be entitled to the same
benefits under this Indenture as definitive Securities of such series
authenticated and delivered hereunder.

      SECTION 2.7 MUTILATED, DESTROYED, LOST OR STOLEN SECURITIES.

      In case any temporary or definitive Security shall become mutilated or be
destroyed, lost or stolen, the Company (subject to the next succeeding sentence)
shall execute, and upon the Company's request the Trustee (subject as aforesaid)
shall authenticate and deliver, a new Security of the same series, bearing a
number not contemporaneously outstanding, in exchange and substitution for the
mutilated Security, or in lieu of and in substitution for the Security so
destroyed, lost or stolen. In every case the applicant for a substituted
Security shall furnish to the Company and the Trustee such security or indemnity
as may be required by them to save each of them harmless, and, in every case of
destruction, loss or theft, the applicant shall also furnish to the Company and
the Trustee evidence to their satisfaction of the destruction, loss or theft of
the applicant's Security and of the ownership thereof. The Trustee may
authenticate any such substituted Security and deliver the same upon the written
request or authorization of any officer of the Company. Upon the issuance of any
substituted Security, the Company may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee)
connected therewith.

      In case any Security that has matured or is about to mature shall become
mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a
substitute Security, pay or

                                       11
<PAGE>

authorize the payment of the same (without surrender thereof except in the case
of a mutilated Security) if the applicant for such payment shall furnish to the
Company and the Trustee such security or indemnity as they may require to save
them harmless, and, in case of destruction, loss or theft, evidence to the
satisfaction of the Company and the Trustee of the destruction, loss or theft of
such Security and of the ownership thereof.

      Every replacement Security issued pursuant to the provisions of this
Section shall constitute an additional contractual obligation of the Company
whether or not the mutilated, destroyed, lost or stolen Security shall be found
at any time, or be enforceable by anyone, and shall be entitled to all the
benefits of this Indenture equally and proportionately with any and all other
Securities of the same series duly issued hereunder. All Securities shall be
held and owned upon the express condition that the foregoing provisions are
exclusive with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities, and shall preclude (to the extent lawful) any and all
other rights or remedies, notwithstanding any law or statute existing or
hereafter enacted to the contrary with respect to the replacement or payment of
negotiable instruments or other securities without their surrender.

      SECTION 2.8 CANCELLATION.

      All Securities surrendered for the purpose of payment, redemption,
exchange or registration of transfer shall, if surrendered to the Company or any
paying agent, be delivered to the Trustee for cancellation, or, if surrendered
to the Trustee, shall be cancelled by it, and no Securities shall be issued in
lieu thereof except as expressly required or permitted by any of the provisions
of this Indenture. On request of the Company at the time of such surrender, the
Trustee shall deliver to the Company canceled Securities held by the Trustee. In
the absence of such request the Trustee may dispose of canceled Securities in
accordance with its standard procedures and deliver a certificate of disposition
to the Company. If the Company shall otherwise acquire any of the Securities,
however, such acquisition shall not operate as a redemption or satisfaction of
the indebtedness represented by such Securities unless and until the same are
delivered to the Trustee for cancellation.

      SECTION 2.9 BENEFITS OF INDENTURE.

      Nothing in this Indenture or in the Securities, express or implied, shall
give or be construed to give to any Person, other than the parties hereto and
the holders of the Securities any legal or equitable right, remedy or claim
under or in respect of this Indenture, or under any covenant, condition or
provision herein contained; all such covenants, conditions and provisions being
for the sole benefit of the parties hereto and of the holders of the Securities.

      SECTION 2.10 AUTHENTICATING AGENT.

      So long as any of the Securities of any series remain Outstanding there
may be an Authenticating Agent for any or all such series of Securities which
the Trustee shall have the right to appoint. Said Authenticating Agent shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon exchange, transfer or partial redemption thereof, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. All

                                       12
<PAGE>

references in this Indenture to the authentication of Securities by the Trustee
shall be deemed to include authentication by an Authenticating Agent for such
series. Each Authenticating Agent shall be acceptable to the Company and shall
be a corporation that has a combined capital and surplus, as most recently
reported or determined by it, sufficient under the laws of any jurisdiction
under which it is organized or in which it is doing business to conduct a trust
business, and that is otherwise authorized under such laws to conduct such
business and is subject to supervision or examination by federal or state
authorities. If at any time any Authenticating Agent shall cease to be eligible
in accordance with these provisions, it shall resign immediately.

      Any Authenticating Agent may at any time resign by giving written notice
of resignation to the Trustee and to the Company. The Trustee may at any time
(and upon request by the Company shall) terminate the agency of any
Authenticating Agent by giving written notice of termination to such
Authenticating Agent and to the Company. Upon resignation, termination or
cessation of eligibility of any Authenticating Agent, the Trustee may appoint an
eligible successor Authenticating Agent acceptable to the Company. Any successor
Authenticating Agent, upon acceptance of its appointment hereunder, shall become
vested with all the rights, powers and duties of its predecessor hereunder as if
originally named as an Authenticating Agent pursuant hereto.

      SECTION 2.11 GLOBAL SECURITIES.

      (a) If the Company shall establish pursuant to Section 2.1 that the
Securities of a particular series are to be issued as a Global Security, then
the Company shall execute and the Trustee shall, in accordance with Section 2.4,
authenticate and deliver, a Global Security that (i) shall represent, and shall
be denominated in an amount equal to the aggregate principal amount of, all of
the Outstanding Securities of such series, (ii) shall be registered in the name
of the Depositary or its nominee, (iii) shall be delivered by the Trustee to the
Depositary or pursuant to the Depositary's instruction and (iv) shall bear a
legend substantially to the following effect: "Except as otherwise provided in
Section 2.11 of the Indenture, this Security may be transferred, in whole but
not in part, only to another nominee of the Depositary or to a successor
Depositary or to a nominee of such successor Depositary."

      (b) Notwithstanding the provisions of Section 2.5, the Global Security of
a series may be transferred, in whole but not in part and in the manner provided
in Section 2.5, only to another nominee of the Depositary for such series, or to
a successor Depositary for such series selected or approved by the Company or to
a nominee of such successor Depositary.

      (c) If at any time the Depositary for a series of the Securities notifies
the Company that it is unwilling or unable to continue as Depositary for such
series or if at any time the Depositary for such series shall no longer be
registered or in good standing under the Exchange Act, or other applicable
statute or regulation, and a successor Depositary for such series is not
appointed by the Company within 90 days after the Company receives such notice
or becomes aware of such condition, as the case may be, or if an Event of
Default has occurred and is continuing and the Company has received a request
from the Depositary, this Section 2.11 shall no longer be applicable to the
Securities of such series and the Company will execute, and subject to Section
2.4, the Trustee will authenticate and deliver the Securities of such series in
definitive registered

                                       13
<PAGE>

form without coupons, in authorized denominations, and in an aggregate principal
amount equal to the principal amount of the Global Security of such series in
exchange for such Global Security. In addition, the Company may at any time
determine that the Securities of any series shall no longer be represented by a
Global Security and that the provisions of this Section 2.11 shall no longer
apply to the Securities of such series. In such event the Company will execute
and, subject to Section 2.4, the Trustee, upon receipt of an Officers'
Certificate evidencing such determination by the Company, will authenticate and
deliver the Securities of such series in definitive registered form without
coupons, in authorized denominations, and in an aggregate principal amount equal
to the principal amount of the Global Security of such series in exchange for
such Global Security. Upon the exchange of the Global Security for such
Securities in definitive registered form without coupons, in authorized
denominations, the Global Security shall be canceled by the Trustee. Such
Securities in definitive registered form issued in exchange for the Global
Security pursuant to this Section 2.11(c) shall be registered in such names and
in such authorized denominations as the Depositary, pursuant to instructions
from its direct or indirect participants or otherwise, shall instruct the
Trustee. The Trustee shall deliver such Securities to the Depositary for
delivery to the Persons in whose names such Securities are so registered.

                                   ARTICLE 3

              REDEMPTION OF SECURITIES AND SINKING FUND PROVISIONS

      SECTION 3.1 REDEMPTION.

      The Company may redeem the Securities of any series issued hereunder on
and after the dates and in accordance with the terms established for such series
pursuant to Section 2.1 hereof.

      SECTION 3.2 NOTICE OF REDEMPTION.

      (a) In case the Company shall desire to exercise such right to redeem all
or, as the case may be, a portion of the Securities of any series in accordance
with any right the Company reserved for itself to do so pursuant to Section 2.1
hereof, the Company shall, or shall cause the Trustee to, give notice of such
redemption to holders of the Securities of such series to be redeemed by
mailing, first class postage prepaid, a notice of such redemption not less than
30 days and not more than 90 days before the date fixed for redemption of that
series to such holders at their last addresses as they shall appear upon the
Security Register, unless a shorter period is specified in the Securities to be
redeemed. Any notice that is mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the registered
holder receives the notice. In any case, failure duly to give such notice to the
holder of any Security of any series designated for redemption in whole or in
part, or any defect in the notice, shall not affect the validity of the
proceedings for the redemption of any other Securities of such series or any
other series. In the case of any redemption of Securities prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture, the Company shall furnish the Trustee
with an Officers' Certificate evidencing compliance with any such restriction.

      Each such notice of redemption shall specify the date fixed for redemption
and the redemption price at which Securities of that series are to be redeemed,
and shall state that

                                       14
<PAGE>

payment of the redemption price of such Securities to be redeemed will be made
at the office or agency of the Company in the Borough of Manhattan, the City and
State of New York, upon presentation and surrender of such Securities, that
interest accrued to the date fixed for redemption will be paid as specified in
said notice, that from and after said date interest will cease to accrue and
that the redemption is for a sinking fund, if such is the case. If less than all
the Securities of a series are to be redeemed, the notice to the holders of
Securities of that series to be redeemed in part shall specify the particular
Securities to be so redeemed.

      In case any Security is to be redeemed in part only, the notice that
relates to such Security shall state the portion of the principal amount thereof
to be redeemed, and shall state that on and after the redemption date, upon
surrender of such Security, a new Security or Securities of such series in
principal amount equal to the unredeemed portion thereof will be issued.

      (b) If less than all the Securities of a series are to be redeemed, the
Company shall give the Trustee at least 45 days' notice in advance of the date
fixed for redemption as to the aggregate principal amount of Securities of the
series to be redeemed, and thereupon the Trustee shall select, by lot or in such
other manner as it shall deem appropriate and fair in its discretion and that
may provide for the selection of a portion or portions (equal to one thousand
U.S. dollars ($1,000) or any integral multiple thereof) of the principal amount
of such Securities of a denomination larger than $1,000, the Securities to be
redeemed and shall thereafter promptly notify the Company in writing of the
numbers of the Securities to be redeemed, in whole or in part. The Company may,
if and whenever it shall so elect, by delivery of instructions signed on its
behalf by its chief executive officer, president or any senior vice president or
vice president, instruct the Trustee or any paying agent to call all or any part
of the Securities of a particular series for redemption and to give notice of
redemption in the manner set forth in this Section, such notice to be in the
name of the Company or its own name as the Trustee or such paying agent may deem
advisable. In any case in which notice of redemption is to be given by the
Trustee or any such paying agent, the Company shall deliver or cause to be
delivered to, or permit to remain with, the Trustee or such paying agent, as the
case may be, such Security Register, transfer books or other records, or
suitable copies or extracts therefrom, sufficient to enable the Trustee or such
paying agent to give any notice by mail that may be required under the
provisions of this Section.

      SECTION 3.3 PAYMENT UPON REDEMPTION.

      (a) If the giving of notice of redemption shall have been completed as
above provided, the Securities or portions of Securities of the series to be
redeemed specified in such notice shall become due and payable on the date and
at the place stated in such notice at the applicable redemption price, together
with interest accrued to the date fixed for redemption and interest on such
Securities or portions of Securities shall cease to accrue on and after the date
fixed for redemption, unless the Company shall default in the payment of such
redemption price and accrued interest with respect to any such Security or
portion thereof. On presentation and surrender of such Securities on or after
the date fixed for redemption at the place of payment specified in the notice,
said Securities shall be paid and redeemed at the applicable redemption price
for such series, together with interest accrued thereon to the date fixed for
redemption (but if the date fixed for redemption is an interest payment date,
the interest installment payable on

                                       15
<PAGE>

such date shall be payable to the registered holder at the close of business on
the applicable record date pursuant to Section 2.3).

      (b) Upon presentation of any Security of such series that is to be
redeemed in part only, the Company shall execute and the Trustee shall
authenticate and the office or agency where the Security is presented shall
deliver to the holder thereof, at the expense of the Company, a new Security of
the same series of authorized denominations in principal amount equal to the
unredeemed portion of the Security so presented.

      SECTION 3.4 SINKING FUND.

      The provisions of Sections 3.4, 3.5 and 3.6 shall be applicable to any
sinking fund for the retirement of Securities of a series, except as otherwise
specified as contemplated by Section 2.1 for Securities of such series.

      The minimum amount of any sinking fund payment provided for by the terms
of Securities of any series is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment". If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 3.5. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such
series.

      SECTION 3.5 SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

      The Company (i) may deliver Outstanding Securities of a series and (ii)
may apply as a credit Securities of a series that have been redeemed either at
the election of the Company pursuant to the terms of such Securities or through
the application of permitted optional sinking fund payments pursuant to the
terms of such Securities, in each case in satisfaction of all or any part of any
sinking fund payment with respect to the Securities of such series required to
be made pursuant to the terms of such Securities as provided for by the terms of
such series, provided that such Securities have not been previously so credited.
Such Securities shall be received and credited for such purpose by the Trustee
at the redemption price specified in such Securities for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

      SECTION 3.6 REDEMPTION OF SECURITIES FOR SINKING FUND.

      Not less than 45 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of the series, the portion thereof, if any,
that is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 3.5 and the basis for such credit and will, together with
such Officers' Certificate, deliver to the Trustee any Securities to be so
delivered. Not less than 30 days before each such sinking fund payment date the
Trustee shall select the Securities to be redeemed upon such sinking fund
payment date in the manner specified in Section 3.2 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner

                                       16
<PAGE>

provided in Section 3.2. Such notice having been duly given, the redemption of
such Securities shall be made upon the terms and in the manner stated in Section
3.3.

                                    ARTICLE 4
                                    COVENANTS

      SECTION 4.1 PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

      The Company will duly and punctually pay or cause to be paid the principal
of (and premium, if any) and interest on the Securities of that series at the
time and place and in the manner provided herein and established with respect to
such Securities. Payments of principal on the Securities may be made at the time
provided herein and established with respect to such Securities by U.S. dollar
check drawn on and mailed to the address of the Securityholder entitled thereto
as such address shall appear in the Security Register, or U.S. dollar wire
transfer to, a U.S. dollar account (such a wire transfer to be made only to a
Securityholder of an aggregate principal amount of Securities of the applicable
series in excess of U.S. $2,000,000 and only if such Securityholder shall have
furnished wire instructions to the Trustee no later than 15 days prior to the
relevant payment date). Payments of interest on the Securities may be made at
the time provided herein and established with respect to such Securities by U.S.
dollar check mailed to the address of the Securityholder entitled thereto as
such address shall appear in the Security Register, or U.S. dollar wire transfer
to, a U.S. dollar account (such a wire transfer to be made only to a
Securityholder of an aggregate principal amount of Securities of the applicable
series in excess of U.S. $2,000,000 and only if such Securityholder shall have
furnished wire instructions in writing to the Security Registrar and the Trustee
no later than 15 days prior to the relevant payment date).

      SECTION 4.2 MAINTENANCE OF OFFICE OR AGENCY.

      So long as any series of the Securities remain Outstanding, the Company
agrees to maintain an office or agency in the Borough of Manhattan, the City and
State of New York, with respect to each such series and at such other location
or locations as may be designated as provided in this Section 4.2, where (i)
Securities of that series may be presented for payment, (ii) Securities of that
series may be presented as herein above authorized for registration of transfer
and exchange, and (iii) notices and demands to or upon the Company in respect of
the Securities of that series and this Indenture may be given or served, such
designation to continue with respect to such office or agency until the Company
shall, by written notice signed by any officer authorized to sign an Officers'
Certificate and delivered to the Trustee, designate some other office or agency
for such purposes or any of them. If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, notices and
demands. The Company initially appoints the corporate trust office of
[_____________________], an affiliate of the Trustee, located in the Borough of
Manhattan, the City of New York as its paying agent with respect to the
Securities.

                                       17
<PAGE>

      SECTION 4.3 PAYING AGENTS.

      (a) If the Company shall appoint one or more paying agents for all or any
series of the Securities, other than the Trustee, the Company will cause each
such paying agent to execute and deliver to the Trustee an instrument in which
such agent shall agree with the Trustee, subject to the provisions of this
Section:

            (1) that it will hold all sums held by it as such agent for the
      payment of the principal of (and premium, if any) or interest on the
      Securities of that series (whether such sums have been paid to it by the
      Company or by any other obligor of such Securities) in trust for the
      benefit of the Persons entitled thereto;

            (2) that it will give the Trustee notice of any failure by the
      Company (or by any other obligor of such Securities) to make any payment
      of the principal of (and premium, if any) or interest on the Securities of
      that series when the same shall be due and payable;

            (3) that it will, at any time during the continuance of any failure
      referred to in the preceding paragraph (a)(2) above, upon the written
      request of the Trustee, forthwith pay to the Trustee all sums so held in
      trust by such paying agent; and

            (4) that it will perform all other duties of paying agent as set
      forth in this Indenture.

      (b) If the Company shall act as its own paying agent with respect to any
series of the Securities, it will on or before each due date of the principal of
(and premium, if any) or interest on Securities of that series, set aside,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum sufficient to pay such principal (and premium, if any) or interest so
becoming due on Securities of that series until such sums shall be paid to such
Persons or otherwise disposed of as herein provided and will promptly notify the
Trustee of such action, or any failure (by it or any other obligor on such
Securities) to take such action. Whenever the Company shall have one or more
paying agents for any series of Securities, it will, prior to each due date of
the principal of (and premium, if any) or interest on any Securities of that
series, deposit with the paying agent a sum sufficient to pay the principal (and
premium, if any) or interest so becoming due, such sum to be held in trust for
the benefit of the Persons entitled to such principal, premium or interest, and
(unless such paying agent is the Trustee) the Company will promptly notify the
Trustee of this action or failure so to act.

Trustee upon the same terms and conditions as those upon which such sums were
held by the Company or such paying agent; and, upon such payment by the Company
or any paying agent to the Trustee, the Company or such paying agent shall be
released from all further liability with respect to such money.

         REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT

      SECTION 6.1 EVENTS OF DEFAULT.

      (a) Whenever used herein with respect to Securities of a particular
series, "Event of Default" means any one or more of the following events that
has occurred and is continuing:

            (1) the Company defaults in the payment of any installment of
      interest upon any of the Securities of that series, as and when the same
      shall become due and payable, and such default continues for a period of
      90 days; provided, however, that a valid extension of an interest payment
      period by the Company in accordance with the terms of any indenture
      supplemental hereto shall not constitute a default in the payment of
      interest for this purpose;

            (2) the Company defaults in the payment of the principal of (or
      premium, if any, on) any of the Securities of that series as and when the
      same shall become due and payable whether at maturity, upon redemption, by
      declaration or otherwise, or in any payment required by any sinking or
      analogous fund established with respect to that series; provided, however,
      that a valid extension of the maturity of such Securities in accordance
      with the terms of any indenture supplemental hereto shall not constitute a
      default in the payment of principal or premium, if any;

                                       20
<PAGE>

            (3) the Company fails to observe or perform any other of its
      covenants or agreements with respect to that series contained in this
      Indenture or otherwise established with respect to that series of
      Securities pursuant to Section 2.1 hereof (other than a covenant or
      agreement that has been expressly included in this Indenture solely for
      the benefit of one or more series of Securities other than such series)
      for a period of 90 days after the date on which written notice of such
      failure, requiring the same to be remedied and stating that such notice is
      a "Notice of Default" hereunder, shall have been given to the Company by
      the Trustee, by registered or certified mail, or to the Company and the
      Trustee by the holders of at least 25% in principal amount of the
      Securities of that series at the time Outstanding;

            (4) the Company pursuant to or within the meaning of any Bankruptcy
      Law (i) commences a voluntary case, (ii) consents to the entry of an order
      for relief against it in an involuntary case, (iii) consents to the
      appointment of a Custodian of it or for all or substantially all of its
      property or (iv) makes a general assignment for the benefit of its
      creditors; or

            (5) a court of competent jurisdiction enters an order under any
      Bankruptcy Law that (i) is for relief against the Company in an
      involuntary case, (ii) appoints a Custodian of the Company for all or
      substantially all of its property or (iii) orders the liquidation of the
      Company, and the order or decree remains unstayed and in effect for 90
      days.

      (b) In each and every such case (other than an Event of Default specified
in clause (4) or clause (5) above), unless the principal of all the Securities
of that series shall have already become due and payable, either the Trustee or
the holders of not less than 25% in aggregate principal amount of the Securities
of that series then Outstanding hereunder, by notice in writing to the Company
(and to the Trustee if given by such Securityholders), may declare the principal
of (and premium, if any, on) and accrued and unpaid interest on all the
Securities of that series to be due and payable immediately, and upon any such
declaration the same shall become and shall be immediately due and payable. If
an Event of Default specified in clause (4) or clause (5) above occurs, the
principal of and accrued and unpaid interest on all the Securities of that
series shall automatically be immediately due and payable without any
declaration or other act on the part of the Trustee or the holders of the
Securities.

      (c) At any time after the principal of (and premium, if any, on) and
accrued and unpaid interest on the Securities of that series shall have been so
declared due and payable, and before any judgment or decree for the payment of
the moneys due shall have been obtained or entered as hereinafter provided, the
holders of a majority in aggregate principal amount of the Securities of that
series then Outstanding hereunder, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if: (i) the
Company has paid or deposited with the Trustee a sum sufficient to pay all
matured installments of interest upon all the Securities of that series and the
principal of (and premium, if any, on) any and all Securities of that series
that shall have become due otherwise than by acceleration (with interest upon
such principal and premium, if any, and, to the extent that such payment is
enforceable under applicable law, upon overdue installments of interest, at the
rate per annum expressed in the Securities of that series to the date of such
payment or deposit) and the amount payable to the Trustee under Section 7.6, and
(ii) any and all Events of Default under the Indenture with respect

                                       21
<PAGE>

to such series, other than the nonpayment of principal on (and premium, if any,
on) and accrued and unpaid interest on Securities of that series that shall not
have become due by their terms, shall have been remedied or waived as provided
in Section 6.6.

      No such rescission and annulment shall extend to or shall affect any
subsequent default or impair any right consequent thereon.

      (d) In case the Trustee shall have proceeded to enforce any right with
respect to Securities of that series under this Indenture and such proceedings
shall have been discontinued or abandoned because of such rescission or
annulment or for any other reason or shall have been determined adversely to the
Trustee, then and in every such case, subject to any determination in such
proceedings, the Company and the Trustee shall be restored respectively to their
former positions and rights hereunder, and all rights, remedies and powers of
the Company and the Trustee shall continue as though no such proceedings had
been taken.

      SECTION 6.2 COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
      TRUSTEE.

      (a) The Company covenants that (i) in case it shall default in the payment
of any installment of interest on any of the Securities of a series, and such
default shall have continued for a period of 90 Business Days, or (ii) in case
it shall default in the payment of the principal of (or premium, if any, on) any
of the Securities of a series when the same shall have become due and payable,
whether upon maturity of the Securities of a series or upon redemption or upon
declaration or otherwise, or in any payment required by any sinking or analogous
fund established with respect to that series as and when the same shall have
become due and payable, then, upon demand of the Trustee, the Company will pay
to the Trustee, for the benefit of the holders of the Securities of that series,
the whole amount that then shall have been become due and payable on all such
Securities for principal (and premium, if any) or interest, or both, as the case
may be, with interest upon the overdue principal (and premium, if any) and (to
the extent that payment of such interest is enforceable under applicable law)
upon overdue installments of interest at the rate per annum expressed in the
Securities of that series; and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, and the
amount payable to the Trustee under Section 7.6.

      (b) If the Company shall fail to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any action or proceedings at law or in
equity for the collection of the sums so due and unpaid, and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or other obligor upon the
Securities of that series and collect the moneys adjudged or decreed to be
payable in the manner provided by law or equity out of the property of the
Company or other obligor upon the Securities of that series, wherever situated.

      (c) In case of any receivership, insolvency, liquidation, bankruptcy,
reorganization, readjustment, arrangement, composition or judicial proceedings
affecting the Company, or its creditors or property, the Trustee shall have
power to intervene in such proceedings and take any action therein that may be
permitted by the court and shall (except as may be otherwise provided

                                       22
<PAGE>

by law) be entitled to file such proofs of claim and other papers and documents
as may be necessary or advisable in order to have the claims of the Trustee and
of the holders of Securities of such series allowed for the entire amount due
and payable by the Company under the Indenture at the date of institution of
such proceedings and for any additional amount that may become due and payable
by the Company after such date, and to collect and receive any moneys or other
property payable or deliverable on any such claim, and to distribute the same
after the deduction of the amount payable to the Trustee under Section 7.6; and
any receiver, assignee or trustee in bankruptcy or reorganization is hereby
authorized by each of the holders of Securities of such series to make such
payments to the Trustee, and, in the event that the Trustee shall consent to the
making of such payments directly to such Securityholders, to pay to the Trustee
any amount due it under Section 7.6.

      (d) All rights of action and of asserting claims under this Indenture, or
under any of the terms established with respect to Securities of that series,
may be enforced by the Trustee without the possession of any of such Securities,
or the production thereof at any trial or other proceeding relative thereto, and
any such suit or proceeding instituted by the Trustee shall be brought in its
own name as trustee of an express trust, and any recovery of judgment shall,
after provision for payment to the Trustee of any amounts due under Section 7.6,
be for the ratable benefit of the holders of the Securities of such series.

      In case of an Event of Default hereunder, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
most effectual to protect and enforce any of such rights, either at law or in
equity or in bankruptcy or otherwise, whether for the specific enforcement of
any covenant or agreement contained in the Indenture or in aid of the exercise
of any power granted in this Indenture, or to enforce any other legal or
equitable right vested in the Trustee by this Indenture or by law.

      Nothing contained herein shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Securityholder any
plan of reorganization, arrangement, adjustment or composition affecting the
Securities of that series or the rights of any holder thereof or to authorize
the Trustee to vote in respect of the claim of any Securityholder in any such
proceeding.

      SECTION 6.3 APPLICATION OF MONEYS COLLECTED.

      Any moneys collected by the Trustee pursuant to this Article with respect
to a particular series of Securities shall be applied in the following order, at
the date or dates fixed by the Trustee and, in case of the distribution of such
moneys on account of principal (or premium, if any) or interest, upon
presentation of the Securities of that series, and notation thereon of the
payment, if only partially paid, and upon surrender thereof if fully paid:

      FIRST: To the payment of reasonable costs and expenses of collection and
of all amounts payable to the Trustee under Section 7.6;

      SECOND: To the payment of the amounts then due and unpaid upon Securities
of such series for principal (and premium, if any) and interest, in respect of
which or for the benefit of

                                       23
<PAGE>

which such money has been collected, ratably, without preference or priority of
any kind, according to the amounts due and payable on such Securities for
principal (and premium, if any) and interest, respectively; and

      THIRD: To the payment of the remainder, if any, to the Company or any
other Person lawfully entitled thereto.

      SECTION 6.4 LIMITATION ON SUITS.

      No holder of any Security of any series shall have any right by virtue or
by availing of any provision of this Indenture to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Indenture
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless (i) such holder previously shall have given to the Trustee
written notice of an Event of Default and of the continuance thereof with
respect to the Securities of such series specifying such Event of Default, as
hereinbefore provided; (ii) the holders of not less than 25% in aggregate
principal amount of the Securities of such series then Outstanding shall have
made written request upon the Trustee to institute such action, suit or
proceeding in its own name as Trustee hereunder; (iii) such holder or holders
shall have offered to the Trustee such reasonable indemnity as it may require
against the costs, expenses and liabilities to be incurred therein or thereby;
(iv) the Trustee for 90 days after its receipt of such notice, request and offer
of indemnity, shall have failed to institute any such action, suit or proceeding
and (v) during such 90 day period, the holders of a majority in principal amount
of the Securities of that series do not give the Trustee a direction
inconsistent with the request.

      Notwithstanding anything contained herein to the contrary or any other
provisions of this Indenture, the right of any holder of any Security to receive
payment of the principal of (and premium, if any) and interest on such Security,
as therein provided, on or after the respective due dates expressed in such
Security (or in the case of redemption, on the redemption date), or to institute
suit for the enforcement of any such payment on or after such respective dates
or redemption date, shall not be impaired or affected without the consent of
such holder and by accepting a Security hereunder it is expressly understood,
intended and covenanted by the taker and holder of every Security of such series
with every other such taker and holder and the Trustee, that no one or more
holders of Securities of such series shall have any right in any manner
whatsoever by virtue or by availing of any provision of this Indenture to
affect, disturb or prejudice the rights of the holders of any other of such
Securities, or to obtain or seek to obtain priority over or preference to any
other such holder, or to enforce any right under this Indenture, except in the
manner herein provided and for the equal, ratable and common benefit of all
holders of Securities of such series. For the protection and enforcement of the
provisions of this Section, each and every Securityholder and the Trustee shall
be entitled to such relief as can be given either at law or in equity.

      SECTION 6.5 RIGHTS AND REMEDIES CUMULATIVE; DELAY OR OMISSION NOT WAIVER.

      (a) Except as otherwise provided in Section 2.7, all powers and remedies
given by this Article to the Trustee or to the Securityholders shall, to the
extent permitted by law, be deemed cumulative and not exclusive of any other
powers and remedies available to the Trustee or the

                                       24
<PAGE>

holders of the Securities, by judicial proceedings or otherwise, to enforce the
performance or observance of the covenants and agreements contained in this
Indenture or otherwise established with respect to such Securities.

      (b) No delay or omission of the Trustee or of any holder of any of the
Securities to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power, or
shall be construed to be a waiver of any such default or an acquiescence
therein; and, subject to the provisions of Section 6.4, every power and remedy
given by this Article or by law to the Trustee or the Securityholders may be
exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Securityholders.

      SECTION 6.6 CONTROL BY SECURITYHOLDERS.

      The holders of a majority in aggregate principal amount of the Securities
of any series at the time Outstanding, determined in accordance with Section
8.4, shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred on the Trustee with respect to such series; provided, however,
that such direction shall not be in conflict with any rule of law or with this
Indenture. Subject to the provisions of Section 7.1, the Trustee shall have the
right to decline to follow any such direction if the Trustee in good faith
shall, by a Responsible Officer or officers of the Trustee, determine that the
proceeding so directed, subject to the Trustee's duties under the Trust
Indenture Act, would involve the Trustee in personal liability or might be
unduly prejudicial to the Securityholders not involved in the proceeding. The
holders of a majority in aggregate principal amount of the Securities of any
series at the time Outstanding affected thereby, determined in accordance with
Section 8.4, may on behalf of the holders of all of the Securities of such
series waive any past default in the performance of any of the covenants
contained herein or established pursuant to Section 2.1 with respect to such
series and its consequences, except a default in the payment of the principal
of, or premium, if any, or interest on, any of the Securities of that series as
and when the same shall become due by the terms of such Securities otherwise
than by acceleration (unless such default has been cured and a sum sufficient to
pay all matured installments of interest and principal and any premium has been
deposited with the Trustee (in accordance with Section 6.1(c)). Upon any such
waiver, the default covered thereby shall be deemed to be cured for all purposes
of this Indenture and the Company, the Trustee and the holders of the Securities
of such series shall be restored to their former positions and rights hereunder,
respectively; but no such waiver shall extend to any subsequent or other default
or impair any right consequent thereon.

      SECTION 6.7 UNDERTAKING TO PAY COSTS.

      All parties to this Indenture agree, and each holder of any Securities by
such holder's acceptance thereof shall be deemed to have agreed, that any court
may in its discretion require, in any suit for the enforcement of any right or
remedy under this Indenture, or in any suit against the Trustee for any action
taken or omitted by it as Trustee, the filing by any party litigant in such suit
of an undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party

                                       25
<PAGE>

litigant; but the provisions of this Section shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Securityholder, or
group of Securityholders, holding more than 10% in aggregate principal amount of
the Outstanding Securities of any series, or to any suit instituted by any
Securityholder for the enforcement of the payment of the principal of (or
premium, if any) or interest on any Security of such series, on or after the
respective due dates expressed in such Security or established pursuant to this
Indenture.

                             CONCERNING THE TRUSTEE

      SECTION 7.1 CERTAIN DUTIES AND RESPONSIBILITIES OF TRUSTEE.

      (a) The Trustee, prior to the occurrence of an Event of Default with
respect to the Securities of a series and after the curing of all Events of
Default with respect to the Securities of that series that may have occurred,
shall undertake to perform with respect to the Securities of such series such
duties and only such duties as are specifically set forth in this Indenture, and
no implied covenants shall be read into this Indenture against the Trustee. In
case an Event of Default with respect to the Securities of a series has occurred
(that has not been cured or waived), the Trustee shall exercise with respect to
Securities of that series such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

      (b) No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act, or its own willful misconduct, except that:

            (i) prior to the occurrence of an Event of Default with respect to
      the Securities of a series and after the curing or waiving of all such
      Events of Default with respect to that series that may have occurred:

                  (A) the duties and obligations of the Trustee shall with
            respect to the Securities of such series be determined solely by the
            express provisions of this Indenture, and the Trustee shall not be
            liable with respect to the Securities of such series except for the
            performance of such duties and obligations as are specifically set
            forth in this Indenture, and no implied covenants or obligations
            shall be read into this Indenture against the Trustee; and

                  (B) in the absence of bad faith on the part of the Trustee,
            the Trustee may with respect to the Securities of such series
            conclusively rely, as to the truth of the statements and the
            correctness of the opinions expressed therein, upon any certificates
            or opinions furnished to the Trustee and conforming to the
            requirements of this Indenture; but in the case of any such
            certificates or opinions that by any provision hereof are
            specifically required to be furnished to the Trustee, the Trustee
            shall be under a duty to examine the same to determine whether or
            not they conform to the requirement of this Indenture;

                                       26
<PAGE>

            (ii) the Trustee shall not be liable for any error of judgment made
      in good faith by a Responsible Officer or Responsible Officers of the
      Trustee, unless it shall be proved that the Trustee was negligent in
      ascertaining the pertinent facts;

            (iii) the Trustee shall not be liable with respect to any action
      taken or omitted to be taken by it in good faith in accordance with the
      direction of the holders of not less than a majority in principal amount
      of the Securities of any series at the time Outstanding relating to the
      time, method and place of conducting any proceeding for any remedy
      available to the Trustee, or exercising any trust or power conferred upon
      the Trustee under this Indenture with respect to the Securities of that
      series; and

            (iv) None of the provisions contained in this Indenture shall
      require the Trustee to expend or risk its own funds or otherwise incur
      personal financial liability in the performance of any of its duties or in
      the exercise of any of its rights or powers if there is reasonable ground
      for believing that the repayment of such funds or liability is not
      reasonably assured to it under the terms of this Indenture or adequate
      indemnity against such risk is not reasonably assured to it.

      SECTION 7.2 CERTAIN RIGHTS OF TRUSTEE.

      Except as otherwise provided in Section 7.1:

      (a) The Trustee may rely and shall be protected in acting or refraining
from acting upon any resolution, certificate, statement, instrument, opinion,
report, notice, request, consent, order, approval, bond, security or other paper
or document believed by it to be genuine and to have been signed or presented by
the proper party or parties;

      (b) Any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by a Board Resolution or an instrument
signed in the name of the Company by any authorized officer of the Company
(unless other evidence in respect thereof is specifically prescribed herein);

      (c) The Trustee may consult with counsel and the written advice of such
counsel or any Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken or suffered or omitted hereunder in
good faith and in reliance thereon;

      (d) The Trustee shall be under no obligation to exercise any of the rights
or powers vested in it by this Indenture at the request, order or direction of
any of the Securityholders pursuant to the provisions of this Indenture, unless
such Securityholders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities that may be incurred
therein or thereby; nothing contained herein shall, however, relieve the Trustee
of the obligation, upon the occurrence of an Event of Default with respect to a
series of the Securities (that has not been cured or waived), to exercise with
respect to Securities of that series such of the rights and powers vested in it
by this Indenture, and to use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs;

                                       27

      (e) The Trustee shall not be liable for any action taken or omitted to be
taken by it in good faith and believed by it to be authorized or within the
discretion or rights or powers conferred upon it by this Indenture;

      (f) The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, security, or
other papers or documents, unless requested in writing so to do by the holders
of not less than a majority in principal amount of the Outstanding Securities of
the particular series affected thereby (determined as provided in Section 8.4);
provided, however, that if the payment within a reasonable time to the Trustee
of the costs, expenses or liabilities likely to be incurred by it in the making
of such investigation is, in the opinion of the Trustee, not reasonably assured
to the Trustee by the security afforded to it by the terms of this Indenture,
the Trustee may require reasonable indemnity against such costs, expenses or
liabilities as a condition to so proceeding. The reasonable expense of every
such examination shall be paid by the Company or, if paid by the Trustee, shall
be repaid by the Company upon demand; and

      (g) The Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder.

      SECTION 7.3 TRUSTEE NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OR
      SECURITIES.

      (a) The recitals contained herein and in the Securities shall be taken as
the statements of the Company, and the Trustee assumes no responsibility for the
correctness of the same.

      (b) The Trustee makes no representations as to the validity or sufficiency
of this Indenture or of the Securities.

      (c) The Trustee shall not be accountable for the use or application by the
Company of any of the Securities or of the proceeds of such Securities, or for
the use or application of any moneys paid over by the Trustee in accordance with
any provision of this Indenture or established pursuant to Section 2.1, or for
the use or application of any moneys received by any paying agent other than the
Trustee.

      SECTION 7.4 MAY HOLD SECURITIES.

      The Trustee or any paying agent or Security Registrar, in its individual
or any other capacity, may become the owner or pledgee of Securities with the
same rights it would have if it were not Trustee, paying agent or Security
Registrar.

      SECTION 7.5 MONEYS HELD IN TRUST.

      Subject to the provisions of Section 11.5, all moneys received by the
Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received, but need not be segregated from other
funds except to the extent required by law. The

                                       28
<PAGE>

Trustee shall be under no liability for interest on any moneys received by it
hereunder except such as it may agree with the Company to pay thereon.

      SECTION 7.6 COMPENSATION AND REIMBURSEMENT.

      (a) The Company covenants and agrees to pay to the Trustee, and the
Trustee shall be entitled to, such reasonable compensation (which shall not be
limited by any provision of law in regard to the compensation of a trustee of an
express trust) as the Company and the Trustee may from time to time agree in
writing, for all services rendered by it in the execution of the trusts hereby
created and in the exercise and performance of any of the powers and duties
hereunder of the Trustee, and, except as otherwise expressly provided herein,
the Company will pay or reimburse the Trustee upon its request for all
reasonable expenses, disbursements and advances incurred or made by the Trustee
in accordance with any of the provisions of this Indenture (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all Persons not regularly in its employ), except any such expense, disbursement
or advance as may arise from its negligence or bad faith and except as the
Company and Trustee may from time to time agree in writing. The Company also
covenants to indemnify the Trustee (and its officers, agents, directors and
employees) for, and to hold it harmless against, any loss, liability or expense
incurred without negligence or bad faith on the part of the Trustee and arising
out of or in connection with the acceptance or administration of this trust,
including the reasonable costs and expenses of defending itself against any
claim of liability in the premises.

      (b) The obligations of the Company under this Section to compensate and
indemnify the Trustee and to pay or reimburse the Trustee for reasonable
expenses, disbursements and advances shall constitute additional indebtedness
hereunder. Such additional indebtedness shall be secured by a lien prior to that
of the Securities upon all property and funds held or collected by the Trustee
as such, except funds held in trust for the benefit of the holders of particular
Securities.

      SECTION 7.7 RELIANCE ON OFFICERS' CERTIFICATE.

      Except as otherwise provided in Section 7.1, whenever in the
administration of the provisions of this Indenture the Trustee shall deem it
reasonably necessary or desirable that a matter be proved or established prior
to taking or suffering or omitting to take any action hereunder, such matter
(unless other evidence in respect thereof be herein specifically prescribed)
may, in the absence of negligence or bad faith on the part of the Trustee, be
deemed to be conclusively proved and established by an Officers' Certificate
delivered to the Trustee and such certificate, in the absence of negligence or
bad faith on the part of the Trustee, shall be full warrant to the Trustee for
any action taken, suffered or omitted to be taken by it under the provisions of
this Indenture upon the faith thereof.

      SECTION 7.8 DISQUALIFICATION; CONFLICTING INTERESTS.

      If the Trustee has or shall acquire any "conflicting interest" within the
meaning of Section 310(b) of the Trust Indenture Act, the Trustee and the
Company shall in all respects comply with the provisions of Section 310(b) of
the Trust Indenture Act.

                                       29

      SECTION 7.9 CORPORATE TRUSTEE REQUIRED; ELIGIBILITY.

      There shall at all times be a Trustee with respect to the Securities
issued hereunder which shall at all times be a corporation organized and doing
business under the laws of the United States of America or any state or
territory thereof or of the District of Columbia, or a corporation or other
Person permitted to act as trustee by the Securities and Exchange Commission,
authorized under such laws to exercise corporate trust powers, having (or, in
the case of a subsidiary of a bank holding company, its bank holding company
parent shall have) a combined capital and surplus of at least fifty million U.S.
dollars ($50,000,000), and subject to supervision or examination by federal,
state, territorial, or District of Columbia authority.

      If such corporation or other Person publishes reports of condition at
least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such corporation or other Person shall be deemed
to be its combined capital and surplus as set forth in its most recent report of
condition so published. The Company may not, nor may any Person directly or
indirectly controlling, controlled by, or under common control with the Company,
serve as Trustee. In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, the Trustee shall resign
immediately in the manner and with the effect specified in Section 7.10.

      SECTION 7.10 RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

      (a) The Trustee or any successor hereafter appointed may at any time
resign with respect to the Securities of one or more series by giving written
notice thereof to the Company and by transmitting notice of resignation by mail,
first class postage prepaid, to the Securityholders of such series, as their
names and addresses appear upon the Security Register. Upon receiving such
notice of resignation, the Company shall promptly appoint a successor trustee
with respect to Securities of such series by written instrument, in duplicate,
executed by order of the Board of Directors, one copy of which instrument shall
be delivered to the resigning Trustee and one copy to the successor trustee. If
no successor trustee shall have been so appointed and have accepted appointment
within 30 days after the mailing of such notice of resignation, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of
a successor trustee with respect to Securities of such series, or any
Securityholder of that series who has been a bona fide holder of a Security or
Securities for at least six months may on behalf of himself and all others
similarly situated, petition any such court for the appointment of a successor
trustee. Such court may thereupon after such notice, if any, as it may deem
proper and prescribe, appoint a successor trustee.

      (b) In case at any time any one of the following shall occur:

            (i) the Trustee shall fail to comply with the provisions of Section
      7.8 after written request therefor by the Company or by any Securityholder
      who has been a bona fide holder of a Security or Securities for at least
      six months; or

                                       30
<PAGE>

            (ii) the Trustee shall cease to be eligible in accordance with the
      provisions of Section 7.9 and shall fail to resign after written request
      therefor by the Company or by any such Securityholder; or

            (iii) the Trustee shall become incapable of acting, or shall be
      adjudged a bankrupt or insolvent, or commence a voluntary bankruptcy
      proceeding, or a receiver of the Trustee or of its property shall be
      appointed or consented to, or any public officer shall take charge or
      control of the Trustee or of its property or affairs for the purpose of
      rehabilitation, conservation or liquidation;

      then, in any such case, the Company may remove the Trustee with respect to
all Securities and appoint a successor trustee by written instrument, in
duplicate, executed by order of the Board of Directors, one copy of which
instrument shall be delivered to the Trustee so removed and one copy to the
successor trustee, or any Securityholder who has been a bona fide holder of a
Security or Securities for at least six months may, on behalf of that holder and
all others similarly situated, petition any court of competent jurisdiction for
the removal of the Trustee and the appointment of a successor trustee. Such
court may thereupon after such notice, if any, as it may deem proper and
prescribe, remove the Trustee and appoint a successor trustee.

      (c) The holders of a majority in aggregate principal amount of the
Securities of any series at the time Outstanding may at any time remove the
Trustee with respect to such series by so notifying the Trustee and the Company
and may appoint a successor Trustee for such series with the consent of the
Company.

      (d) Any resignation or removal of the Trustee and appointment of a
successor trustee with respect to the Securities of a series pursuant to any of
the provisions of this Section shall become effective upon acceptance of
appointment by the successor trustee as provided in Section 7.11.

      (e) Any successor trustee appointed pursuant to this Section may be
appointed with respect to the Securities of one or more series or all of such
series, and at any time there shall be only one Trustee with respect to the
Securities of any particular series.

      SECTION 7.11 ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

      (a) In case of the appointment hereunder of a successor trustee with
respect to all Securities, every such successor trustee so appointed shall
execute, acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on the request
of the Company or the successor trustee, such retiring Trustee shall, upon
payment of its charges, execute and deliver an instrument transferring to such
successor trustee all the rights, powers, and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor trustee all property
and money held by such retiring Trustee hereunder.

      (b) In case of the appointment hereunder of a successor trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each

                                       31
<PAGE>

successor trustee with respect to the Securities of one or more series shall
execute and deliver an indenture supplemental hereto wherein each successor
trustee shall accept such appointment and which (i) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor trustee relates, (ii) shall contain such
provisions as shall be deemed necessary or desirable to confirm that all the
rights, powers, trusts and duties of the retiring Trustee with respect to the
Securities of that or those series as to which the retiring Trustee is not
retiring shall continue to be vested in the retiring Trustee, and (iii) shall
add to or change any of the provisions of this Indenture as shall be necessary
to provide for or facilitate the administration of the trusts hereunder by more
than one Trustee, it being understood that nothing herein or in such
supplemental indenture shall constitute such Trustees co-trustees of the same
trust, that each such Trustee shall be trustee of a trust or trusts hereunder
separate and apart from any trust or trusts hereunder administered by any other
such Trustee and that no Trustee shall be responsible for any act or failure to
act on the part of any other Trustee hereunder; and upon the execution and
delivery of such supplemental indenture the resignation or removal of the
retiring Trustee shall become effective to the extent provided therein, such
retiring Trustee shall with respect to the Securities of that or those series to
which the appointment of such successor trustee relates have no further
responsibility for the exercise of rights and powers or for the performance of
the duties and obligations vested in the Trustee under this Indenture, and each
such successor trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the
appointment of such successor trustee relates; but, on request of the Company or
any successor trustee, such retiring Trustee shall duly assign, transfer and
deliver to such successor trustee, to the extent contemplated by such
supplemental indenture, the property and money held by such retiring Trustee
hereunder with respect to the Securities of that or those series to which the
appointment of such successor trustee relates.

      (c) Upon request of any such successor trustee, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor trustee all such rights, powers and trusts referred to in
paragraph (a) or (b) of this Section, as the case may be.

      (d) No successor trustee shall accept its appointment unless at the time
of such acceptance such successor trustee shall be qualified and eligible under
this Article.

      (e) Upon acceptance of appointment by a successor trustee as provided in
this Section, the Company shall transmit notice of the succession of such
trustee hereunder by mail, first class postage prepaid, to the Securityholders,
as their names and addresses appear upon the Security Register. If the Company
fails to transmit such notice within ten days after acceptance of appointment by
the successor trustee, the successor trustee shall cause such notice to be
transmitted at the expense of the Company.

      SECTION 7.12 MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

      Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee (including the administration of the trust created by
this Indenture), shall be the successor of the Trustee hereunder, provided that
such corporation shall be qualified under the provisions of Section 7.8 and
eligible under the provisions of Section 7.9, without the execution or filing of
any paper or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

      SECTION 7.13 PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE COMPANY.

      The Trustee shall comply with Section 311(a) of the Trust Indenture Act,
excluding any creditor relationship described in Section 311(b) of the Trust
Indenture Act. A Trustee who has resigned or been removed shall be subject to
Section 311(a) of the Trust Indenture Act to the extent included therein.

      SECTION 7.14 NOTICE OF DEFAULT.

      If any Default or any Event of Default occurs and is continuing and if
such Default or Event of Default is known to a Responsible Officer of the
Trustee, the Trustee shall mail to each Securityholder in the manner and to the
extent provided in Section 313(c) of the Trust Indenture Act notice of the
Default or Event of Default within 45 days after it occurs, unless such Default
or Event of Default has been cured; provided, however, that, except in the case
of a default in the payment of the principal of (or premium, if any) or interest
on any Security, the Trustee shall be protected in withholding such notice if
and so long as the board of directors, the executive committee or a trust
committee of directors and/or Responsible Officers of the Trustee in good faith
determine that the withholding of such notice is in the interest of the
Securityholders.

                                    ARTICLE 8
                         CONCERNING THE SECURITYHOLDERS

      SECTION 8.1 EVIDENCE OF ACTION BY SECURITYHOLDERS.

      Whenever in this Indenture it is provided that the holders of a majority
or specified percentage in aggregate principal amount of the Securities of a
particular series may take any action (including the making of any demand or
request, the giving of any notice, consent or waiver or the taking of any other
action), the fact that at the time of taking any such action the holders of such
majority or specified percentage of that series have joined therein may be
evidenced by any instrument or any number of instruments of similar tenor
executed by such holders of Securities of that series in person or by agent or
proxy appointed in writing.

                                       33
<PAGE>

      If the Company shall solicit from the Securityholders of any series any
request, demand, authorization, direction, notice, consent, waiver or other
action, the Company may, at its option, as evidenced by an Officers'
Certificate, fix in advance a record date for such series for the determination
of Securityholders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other action, but the Company shall have
no obligation to do so. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other action may be given
before or after the record date, but only the Securityholders of record at the
close of business on the record date shall be deemed to be Securityholders for
the purposes of determining whether Securityholders of the requisite proportion
of Outstanding Securities of that series have authorized or agreed or consented
to such request, demand, authorization, direction, notice, consent, waiver or
other action, and for that purpose the Outstanding Securities of that series
shall be computed as of the record date; provided, however, that no such
authorization, agreement or consent by such Securityholders on the record date
shall be deemed effective unless it shall become effective pursuant to the
provisions of this Indenture not later than six months after the record date.

      SECTION 8.2 PROOF OF EXECUTION BY SECURITYHOLDERS.

      Subject to the provisions of Section 7.1, proof of the execution of any
instrument by a Securityholder (such proof will not require notarization) or his
agent or proxy and proof of the holding by any Person of any of the Securities
shall be sufficient if made in the following manner:

      (a) The fact and date of the execution by any such Person of any
instrument may be proved in any reasonable manner acceptable to the Trustee.

      (b) The ownership of Securities shall be proved by the Security Register
of such Securities or by a certificate of the Security Registrar thereof.

      The Trustee may require such additional proof of any matter referred to in
this Section as it shall deem necessary.

      SECTION 8.3 WHO MAY BE DEEMED OWNERS.

      Prior to the due presentment for registration of transfer of any Security,
the Company, the Trustee, any paying agent and any Security Registrar may deem
and treat the Person in whose name such Security shall be registered upon the
books of the Company as the absolute owner of such Security (whether or not such
Security shall be overdue and notwithstanding any notice of ownership or writing
thereon made by anyone other than the Security Registrar) for the purpose of
receiving payment of or on account of the principal of, premium, if any, and
(subject to Section 2.3) interest on such Security and for all other purposes;
and neither the Company nor the Trustee nor any paying agent nor any Security
Registrar shall be affected by any notice to the contrary.

      SECTION 8.4 CERTAIN SECURITIES OWNED BY COMPANY DISREGARDED.

      In determining whether the holders of the requisite aggregate principal
amount of Securities of a particular series have concurred in any direction,
consent or waiver under this

                                       34
<PAGE>

Indenture, the Securities of that series that are owned by the Company or any
other obligor on the Securities of that series or by any Person directly or
indirectly controlling or controlled by or under common control with the Company
or any other obligor on the Securities of that series shall be disregarded and
deemed not to be Outstanding for the purpose of any such determination, except
that for the purpose of determining whether the Trustee shall be protected in
relying on any such direction, consent or waiver, only Securities of such series
that the Trustee actually knows are so owned shall be so disregarded. The
Securities so owned that have been pledged in good faith may be regarded as
Outstanding for the purposes of this Section, if the pledgee shall establish to
the satisfaction of the Trustee the pledgee's right so to act with respect to
such Securities and that the pledgee is not a Person directly or indirectly
controlling or controlled by or under direct or indirect common control with the
Company or any such other obligor. In case of a dispute as to such right, any
decision by the Trustee taken upon the advice of counsel shall be full
protection to the Trustee.

      SECTION 8.5 ACTIONS BINDING ON FUTURE SECURITYHOLDERS.

      At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 8.1, of the taking of any action by the holders of the
majority or percentage in aggregate principal amount of the Securities of a
particular series specified in this Indenture in connection with such action,
any holder of a Security of that series that is shown by the evidence to be
included in the Securities the holders of which have consented to such action
may, by filing written notice with the Trustee, and upon proof of holding as
provided in Section 8.2, revoke such action so far as concerns such Security.
Except as aforesaid any such action taken by the holder of any Security shall be
conclusive and binding upon such holder and upon all future holders and owners
of such Security, and of any Security issued in exchange therefor, on
registration of transfer thereof or in place thereof, irrespective of whether or
not any notation in regard thereto is made upon such Security. Any action taken
by the holders of the majority or percentage in aggregate principal amount of
the Securities of a particular series specified in this Indenture in connection
with such action shall be conclusively binding upon the Company, the Trustee and
the holders of all the Securities of that series.

                                    ARTICLE 9
                             SUPPLEMENTAL INDENTURES

      SECTION 9.1 SUPPLEMENTAL INDENTURES WITHOUT THE CONSENT OF
      SECURITYHOLDERS.

      In addition to any supplemental indenture otherwise authorized by this
Indenture, the Company and the Trustee may from time to time and at any time
enter into an indenture or indentures supplemental hereto (which shall conform
to the provisions of the Trust Indenture Act as then in effect), without the
consent of the Securityholders, for one or more of the following purposes:

      (a) to cure any ambiguity, defect, or inconsistency herein or in the
Securities of any series;

      (b) to comply with Article Ten;

                                       35
<PAGE>

      (c) to provide for uncertificated Securities in addition to or in place of
certificated Securities;

      (d) to add to the covenants, restrictions, conditions or provisions
relating to the Company for the benefit of the holders of all or any series of
Securities (and if such covenants, restrictions, conditions or provisions are to
be for the benefit of less than all series of Securities, stating that such
covenants, restrictions, conditions or provisions are expressly being included
solely for the benefit of such series), to make the occurrence, or the
occurrence and the continuance, of a default in any such additional covenants,
restrictions, conditions or provisions an Event of Default, or to surrender any
right or power herein conferred upon the Company;

      (e) to add to, delete from, or revise the conditions, limitations, and
restrictions on the authorized amount, terms, or purposes of issue,
authentication, and delivery of Securities, as herein set forth;

      (f) to make any change that does not adversely affect the rights of any
Securityholder in any material respect;

      (g) to provide for the issuance of and establish the form and terms and
conditions of the Securities of any series as provided in Section 2.1, to
establish the form of any certifications required to be furnished pursuant to
the terms of this Indenture or any series of Securities, or to add to the rights
of the holders of any series of Securities;

      (h) to evidence and provide for the acceptance of appointment hereunder by
a successor trustee; or

      (i) to comply with any requirements of the Securities and Exchange
Commission or any successor in connection with the qualification of this
Indenture under the Trust Indenture Act.

      The Trustee is hereby authorized to join with the Company in the execution
of any such supplemental indenture, and to make any further appropriate
agreements and stipulations that may be therein contained, but the Trustee shall
not be obligated to enter into any such supplemental indenture that affects the
Trustee's own rights, duties or immunities under this Indenture or otherwise.

      Any supplemental indenture authorized by the provisions of this Section
may be executed by the Company and the Trustee without the consent of the
holders of any of the Securities at the time Outstanding, notwithstanding any of
the provisions of Section 9.2.

      SECTION 9.2 SUPPLEMENTAL INDENTURES WITH CONSENT OF SECURITYHOLDERS.

      With the consent (evidenced as provided in Section 8.1) of the holders of
not less than a majority in aggregate principal amount of the Securities of each
series affected by such supplemental indenture or indentures at the time
Outstanding, the Company, when authorized by a Board Resolution, and the Trustee
may from time to time and at any time enter into an indenture or indentures
supplemental hereto (which shall conform to the provisions of the Trust
Indenture Act as then in effect) for the purpose of adding any provisions to or
changing in any

                                       36
<PAGE>

manner or eliminating any of the provisions of this Indenture or of any
supplemental indenture or of modifying in any manner not covered by Section 9.1
the rights of the holders of the Securities of such series under this Indenture;
provided, however, that no such supplemental indenture shall, without the
consent of the holders of each Security then Outstanding and affected thereby,
(a) extend the fixed maturity of any Securities of any series, or reduce the
principal amount thereof, or reduce the rate or extend the time of payment of
interest thereon, or reduce any premium payable upon the redemption thereof or
(b) reduce the aforesaid percentage of Securities, the holders of which are
required to consent to any such supplemental indenture.

      It shall not be necessary for the consent of the Securityholders of any
series affected thereby under this Section to approve the particular form of any
proposed supplemental indenture, but it shall be sufficient if such consent
shall approve the substance thereof.

      SECTION 9.3 EFFECT OF SUPPLEMENTAL INDENTURES.

      Upon the execution of any supplemental indenture pursuant to the
provisions of this Article or of Section 10.1, this Indenture shall, with
respect to such series, be and be deemed to be modified and amended in
accordance therewith and the respective rights, limitations of rights,
obligations, duties and immunities under this Indenture of the Trustee, the
Company and the holders of Securities of the series affected thereby shall
thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments, and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.

      SECTION 9.4 SECURITIES AFFECTED BY SUPPLEMENTAL INDENTURES.

      Securities of any series affected by a supplemental indenture,
authenticated and delivered after the execution of such supplemental indenture
pursuant to the provisions of this Article or of Section 10.1, may bear a
notation in form approved by the Company, provided such form meets the
requirements of any securities exchange upon which such series may be listed, as
to any matter provided for in such supplemental indenture. If the Company shall
so determine, new Securities of that series so modified as to conform, in the
opinion of the Board of Directors, to any modification of this Indenture
contained in any such supplemental indenture may be prepared by the Company,
authenticated by the Trustee and delivered in exchange for the Securities of
that series then Outstanding.

      SECTION 9.5 EXECUTION OF SUPPLEMENTAL INDENTURES.

      Upon the request of the Company, accompanied by its Board Resolutions
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of Securityholders required
to consent thereto as aforesaid, the Trustee shall join with the Company in the
execution of such supplemental indenture unless such supplemental indenture
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion but shall not be
obligated to enter into such supplemental indenture. The Trustee, subject to the
provisions of Section 7.1, may receive an Officers' Certificate or an Opinion of
Counsel as conclusive evidence that any supplemental indenture executed pursuant
to this Article is authorized or permitted by, and conforms to, the

                                       37
<PAGE>

terms of this Article and that it is proper for the Trustee under the provisions
of this Article to join in the execution thereof; provided, however, that such
Officers' Certificate or Opinion of Counsel need not be provided in connection
with the execution of a supplemental indenture that establishes the terms of a
series of Securities pursuant to Section 2.1 hereof.

      Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions of this Section, the Trustee
shall transmit by mail, first class postage prepaid, a notice, setting forth in
general terms the substance of such supplemental indenture, to the
Securityholders of all series affected thereby as their names and addresses
appear upon the Security Register. Any failure of the Trustee to mail such
notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such supplemental indenture.

                                   ARTICLE 10
                                SUCCESSOR ENTITY

      SECTION 10.1 COMPANY MAY CONSOLIDATE, ETC.

      Except as provided pursuant to Section 2.1 pursuant to a Board Resolution,
and set forth in an Officers' Certificate, or established in one or more
indentures supplemental to this Indenture, nothing contained in this Indenture
shall prevent any consolidation or merger of the Company with or into any other
Person (whether or not affiliated with the Company) or successive consolidations
or mergers in which the Company or its successor or successors shall be a party
or parties, or shall prevent any sale, conveyance, transfer or other disposition
of the property of the Company or its successor or successors as an entirety, or
substantially as an entirety, to any other corporation (whether or not
affiliated with the Company or its successor or successors) authorized to
acquire and operate the same; provided, however, the Company hereby covenants
and agrees that, upon any such consolidation or merger (in each case, if the
Company is not the survivor of such transaction), sale, conveyance, transfer or
other disposition, (a) the due and punctual payment of the principal of
(premium, if any) and interest on all of the Securities of all series in
accordance with the terms of each series, according to their tenor, and the due
and punctual performance and observance of all the covenants and conditions of
this Indenture with respect to each series or established with respect to such
series pursuant to Section 2.1 to be kept or performed by the Company shall be
expressly assumed, by supplemental indenture (which shall conform to the
provisions of the Trust Indenture Act, as then in effect) reasonably
satisfactory in form to the Trustee executed and delivered to the Trustee by the
entity formed by such consolidation, or into which the Company shall have been
merged, or by the entity which shall have acquired such property and (b) in the
event that the Securities of any series then Outstanding are convertible into or
exchangeable for shares of common stock or other securities of the Company, such
entity shall, by such supplemental indenture, make provision so that the
Securityholders of Securities of that series shall thereafter be entitled to
receive upon conversion or exchange of such Securities the number of securities
or property to which a holder of the number of shares of common stock or other
securities of the Company deliverable upon conversion or exchange of those
Securities would have been entitled had such conversion or exchange occurred
immediately prior to such consolidation, merger, sale, conveyance, transfer or
other disposition.

<PAGE>

      SECTION 10.2 SUCCESSOR ENTITY SUBSTITUTED.

      (a) In case of any such consolidation, merger, sale, conveyance, transfer
or other disposition and upon the assumption by the successor entity by
supplemental indenture, executed and delivered to the Trustee and satisfactory
in form to the Trustee, of the obligations set forth under Section 10.1 on all
of the Securities of all series Outstanding, such successor entity shall succeed
to and be substituted for the Company with the same effect as if it had been
named as the Company herein, and thereupon the predecessor corporation shall be
relieved of all obligations and covenants under this Indenture and the
Securities.

      (b) In case of any such consolidation, merger, sale, conveyance, transfer
or other disposition, such changes in phraseology and form (but not in
substance) may be made in the Securities thereafter to be issued as may be
appropriate.

      (c) Nothing contained in this Article shall require any action by the
Company in the case of a consolidation or merger of any Person into the Company
where the Company is the survivor of such transaction, or the acquisition by the
Company, by purchase or otherwise, of all or any part of the property of any
other Person (whether or not affiliated with the Company).

      SECTION 10.3 EVIDENCE OF CONSOLIDATION, ETC. TO TRUSTEE.

      The Trustee, subject to the provisions of Section 7.1, may receive an
Officers' Certificate or an Opinion of Counsel as conclusive evidence that any
such consolidation, merger, sale, conveyance, transfer or other disposition, and
any such assumption, comply with the provisions of this Article.

                                   ARTICLE 11
                           SATISFACTION AND DISCHARGE

      SECTION 11.1 SATISFACTION AND DISCHARGE OF INDENTURE.

      If at any time: (a) the Company shall have delivered to the Trustee for
cancellation all Securities of a series theretofore authenticated and not
delivered to the Trustee for cancellation (other than any Securities that shall
have been destroyed, lost or stolen and that shall have been replaced or paid as
provided in Section 2.7 and Securities for whose payment money or Governmental
Obligations have theretofore been deposited in trust or segregated and held in
trust by the Company and thereupon repaid to the Company or discharged from such
trust, as provided in Section 11.5); or (b) all such Securities of a particular
series not theretofore delivered to the Trustee for cancellation shall have
become due and payable, or are by their terms to become due and payable within
one year or are to be called for redemption within one year under arrangements
satisfactory to the Trustee for the giving of notice of redemption, and the
Company shall deposit or cause to be deposited with the Trustee as trust funds
the entire amount in moneys or Governmental Obligations or a combination
thereof, sufficient in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, to pay at maturity or upon redemption all Securities
of that series not theretofore delivered to the Trustee for cancellation,
including principal (and premium, if any) and interest due or to become due to
such date of maturity or date fixed for redemption, as the case may be, and if
the Company shall also pay or cause to be paid all other sums payable

                                       39
<PAGE>

hereunder with respect to such series by the Company then this Indenture shall
thereupon cease to be of further effect with respect to such series except for
the provisions of Sections 2.3, 2.5, 2.7, 4.1, 4.2, 4.3 and 7.10, that shall
survive until the date of maturity or redemption date, as the case may be, and
Sections 7.6 and 11.5, that shall survive to such date and thereafter, and the
Trustee, on demand of the Company and at the cost and expense of the Company
shall execute proper instruments acknowledging satisfaction of and discharging
this Indenture with respect to such series.

      SECTION 11.2 DISCHARGE OF OBLIGATIONS.

      If at any time all such Securities of a particular series not heretofore
delivered to the Trustee for cancellation or that have not become due and
payable as described in Section 11.1 shall have been paid by the Company by
depositing irrevocably with the Trustee as trust funds moneys or an amount of
Governmental Obligations sufficient to pay at maturity or upon redemption all
such Securities of that series not theretofore delivered to the Trustee for
cancellation, including principal (and premium, if any) and interest due or to
become due to such date of maturity or date fixed for redemption, as the case
may be, and if the Company shall also pay or cause to be paid all other sums
payable hereunder by the Company with respect to such series, then after the
date such moneys or Governmental Obligations, as the case may be, are deposited
with the Trustee the obligations of the Company under this Indenture with
respect to such series shall cease to be of further effect except for the
provisions of Sections 2.3, 2.5, 2.7, 4,01, 4.2, 4,03, 7.6, 7.10 and 11.5 hereof
that shall survive until such Securities shall mature and be paid.

      Thereafter, Sections 7.6 and 11.5 shall survive.

      SECTION 11.3 DEPOSITED MONEYS TO BE HELD IN TRUST.

      All moneys or Governmental Obligations deposited with the Trustee pursuant
to Sections 11.1 or 11.2 shall be held in trust and shall be available for
payment as due, either directly or through any paying agent (including the
Company acting as its own paying agent), to the holders of the particular series
of Securities for the payment or redemption of which such moneys or Governmental
Obligations have been deposited with the Trustee.

      SECTION 11.4 PAYMENT OF MONEYS HELD BY PAYING AGENTS.

      In connection with the satisfaction and discharge of this Indenture all
moneys or Governmental Obligations then held by any paying agent under the
provisions of this Indenture shall, upon demand of the Company, be paid to the
Trustee and thereupon such paying agent shall be released from all further
liability with respect to such moneys or Governmental Obligations.

      SECTION 11.5 REPAYMENT TO COMPANY.

      Any moneys or Governmental Obligations deposited with any paying agent or
the Trustee, or then held by the Company, in trust for payment of principal of
or premium, if any, or interest on the Securities of a particular series that
are not applied but remain unclaimed by the holders of such Securities for at
least two years after the date upon which the principal of (and

                                       40
<PAGE>

premium, if any) or interest on such Securities shall have respectively become
due and payable, or such other shorter period set forth in applicable escheat or
abandoned or unclaimed property law, shall be repaid to the Company on May 31 of
each year or upon the Company's request or (if then held by the Company) shall
be discharged from such trust; and thereupon the paying agent and the Trustee
shall be released from all further liability with respect to such moneys or
Governmental Obligations, and the holder of any of the Securities entitled to
receive such payment shall thereafter, as a general creditor, look only to the
Company for the payment thereof.

or successor corporation, either directly or through the Company or any such
predecessor or successor corporation, whether by virtue of any constitution,

issued hereunder are solely corporate obligations, and that no such personal
liability whatever shall attach to, or is or shall be incurred by, the
incorporators, shareholders, officers or directors as such, of the Company or of
any predecessor or successor corporation, or any of them, because of the
creation of the indebtedness hereby authorized, or under or by reason of the

the Securities or implied therefrom; and that any and all such personal
liability of every name and nature, either at common law or in equity or by

every such incorporator, shareholder, officer or director as such, because of
the creation of the indebtedness hereby authorized, or under or by reason of the
obligations, covenants or agreements contained in this Indenture or in any of
the Securities or implied therefrom, are hereby expressly waived and released as
a condition of, and as a consideration for, the execution of this Indenture and
the issuance of such Securities.

the Trust Indenture Act is applicable.

      SECTION 13.6 TREATMENT OF SECURITIES AS DEBT.

      It is intended that the Securities will be treated as indebtedness and not
