         2.       REGISTRATION.
                  ------------

                  a. Mandatory Registration.  The Company shall use best efforts
to keep the Registration  Statement  effective  pursuant to Rule 415 promulgated
under the 1933 Act and available for sales of all of the Registrable  Securities
at all times until the earlier of (i) the date as of which the Investor may sell
all of the Registrable  Securities without  restriction  pursuant to Rule 144(k)
promulgated under the 1933 Act (or successor  thereto) or (ii) the date on which
(A) the Investor shall have sold all the Registrable Securities and no Available
Amount remains under the Purchase  Agreement (the  "Registration  Period").  The
Registration  Statement  (including any  amendments or  supplements  thereto and
prospectuses  contained  therein)  shall not contain any untrue  statement  of a
material fact or omit to state a material fact required to be stated therein, or

applicable securities regulations, from time to time file with the SEC, pursuant

cover  all  of  the  Registrable   Securities,   the  Company  shall  amend  the
Registration Statement or file a new registration statement (a "New Registration
Statement"),  so as to  cover  all of  such  Registrable  Securities  as soon as
practicable,  but in any event not later  than ten (10)  Trading  Days after the
necessity  therefor arises.  The Company shall use it best efforts to cause such
amendment  and/or New  Registration  Statement  to become  effective  as soon as
practicable  following  the filing  thereof.  The Investor and its counsel shall
have a  reasonable  opportunity  to review and comment  upon any such  amendment
and/or New Registration Statement prior to its filing with the SEC. The Investor
shall use its reasonable best efforts to comment upon any such amendment  and/or

         3.       RELATED OBLIGATIONS.
                  -------------------

         With respect to the Registration Statement and whenever any Registrable
Securities  are to be  registered  pursuant  to Section 2  including  on any New
Registration  Statement,  the Company shall use its  reasonable  best efforts to
effect the  registration  of the  Registrable  Securities in accordance with the
intended method of disposition thereof and, pursuant thereto,  the Company shall
have the following obligations:

                  a.  The  Company  shall  prepare  and  file  with the SEC such
amendments  (including   post-effective   amendments)  and  supplements  to  any
registration   statement  and  the  prospectus  used  in  connection  with  such
registration  statement,  which  prospectus is to be filed  pursuant to Rule 424
promulgated  under the 1933 Act, as may be  necessary  to keep the  Registration
Statement or any New  Registration  Statement  effective at all times during the
Registration Period, and, during such period,  comply with the provisions of the
1933 Act with respect to the  disposition of all  Registrable  Securities of the
Company covered by the Registration  Statement or any New Registration Statement
until such time as all of such  Registrable  Securities shall have been disposed
of in  accordance  with the  intended  methods of  disposition  by the seller or
sellers thereof as set forth in such registration statement.

                  b. The Company shall permit the Investor to review and comment
upon  the  Registration  Statement  or any New  Registration  Statement  and all
amendments and supplements  thereto at least two (2) Trading Days prior to their
filing  with the SEC,  and not file  any  document  in a form to which  Investor
reasonably  objects.  The  Investor  shall use its  reasonable  best  efforts to
comment upon the Registration  Statement or any New  Registration  Statement and
any amendments or supplements  thereto within two (2) Trading Days from the date
the Investor  receives the final version  thereof.  The Company shall furnish to
the Investor, without charge any correspondence from the SEC or the staff of the
SEC to the Company or its representatives relating to the Registration Statement
or any New Registration Statement.

                  c. The Company  shall  furnish to the  Investor,  (i) promptly
after the same is  prepared  and filed  with the SEC,  at least one copy of such
registration  statement  and  any  amendment(s)  thereto,   including  financial
statements and schedules,  all documents  incorporated  therein by reference and
all exhibits,  (ii) upon the  effectiveness of any registration  statement,  ten
(10) copies of the prospectus  included in such  registration  statement and all
amendments  and  supplements  thereto  (or such  other  number  of copies as the
Investor  may  reasonably  request)  and (iii) such other  documents,  including
copies of any  preliminary or final  prospectus,  as the Investor may reasonably
request  from  time  to time in  order  to  facilitate  the  disposition  of the
Registrable Securities owned by the Investor.

                  d. The  Company  shall  use  reasonable  best  efforts  to (i)
register  and  qualify  the  Registrable  Securities  covered by a  registration
statement under such other  securities or "blue sky" laws of such  jurisdictions
in the United States as the Investor reasonably requests,  (ii) prepare and file
in those jurisdictions,  such amendments (including  post-effective  amendments)
and supplements to such  registrations and qualifications as may be necessary to
maintain the effectiveness  thereof during the Registration  Period,  (iii) take
such other  actions as may be  necessary  to  maintain  such  registrations  and
qualifications in effect at all times during the Registration  Period,  and (iv)
take all  other  actions  reasonably  necessary  or  advisable  to  qualify  the
Registrable Securities for sale in such jurisdictions;  provided,  however, that
the  Company  shall not be required in  connection  therewith  or as a condition
thereto to (x)  qualify to do business  in any  jurisdiction  where it would not
otherwise be required to qualify but for this Section 3(d),  (y) subject  itself
to general taxation in any such  jurisdiction,  or (z) file a general consent to
service of process in any such  jurisdiction.  The Company shall promptly notify
the

                                      -3-
<PAGE>

Investor who holds  Registrable  Securities of the receipt by the Company of any
notification with respect to the suspension of the registration or qualification
of any of the Registrable Securities for sale under the securities or "blue sky"
laws of any jurisdiction in the United States or its receipt of actual notice of
the initiation or threatening of any proceeding for such purpose.

                  e. As promptly as  practicable  after  becoming  aware of such
event or facts,  the  Company  shall  notify  the  Investor  in  writing  of the
happening  of any  event or  existence  of such  facts as a result  of which the
prospectus included in any registration  statement,  as then in effect, includes
an  untrue  statement  of a  material  fact or omits to  state a  material  fact
required to be stated  therein or necessary to make the statements  therein,  in
light of the  circumstances  under  which they were made,  not  misleading,  and
promptly  prepare a supplement  or amendment to such  registration  statement to
correct such untrue  statement or omission,  and deliver ten (10) copies of such
supplement  or  amendment to the Investor (or such other number of copies as the
Investor may  reasonably  request).  The Company shall also promptly  notify the
Investor  in writing  (i) when a  prospectus  or any  prospectus  supplement  or
post-effective  amendment has been filed,  and when a registration  statement or
any  post-effective   amendment  has  become  effective  (notification  of  such
effectiveness shall be delivered to the Investor by facsimile on the same day of
such  effectiveness  and by overnight mail),  (ii) of any request by the SEC for
amendments or supplements to any registration statement or related prospectus or
related information,  and (iii) of the Company's reasonable determination that a
post-effective amendment to a registration statement would be appropriate.

                  f. The  Company  shall  use its  reasonable  best  efforts  to
prevent the issuance of any stop order or other  suspension of  effectiveness of
any  registration  statement,  or the  suspension  of the  qualification  of any
Registrable  Securities  for sale in any  jurisdiction  and, if such an order or
suspension  is issued,  to obtain the  withdrawal of such order or suspension at
the earliest  possible moment and to notify the Investor of the issuance of such
order  and the  resolution  thereof  or its  receipt  of  actual  notice  of the
initiation or threat of any proceeding for such purpose.

                  g. The Company shall (i) cause all the Registrable  Securities
to be listed on each securities  exchange or trading system on which  securities
of the same class or series  issued by the Company are then  listed,  if any, if
the listing of such Registrable  Securities is then permitted under the rules of
such exchange,  or (ii) secure  designation and quotation of all the Registrable
Securities on the Principal Market.  The Company shall pay all fees and expenses
in connection with satisfying its obligation under this Section.

                  h. The Company shall cooperate with the Investor to facilitate
the timely preparation and delivery of certificates (not bearing any restrictive
legend)  representing  the Registrable  Securities to be offered pursuant to any
registration  statement and enable such certificates to be in such denominations
or amounts as the Investor may  reasonably  request and registered in such names
as the Investor may request.

                  i. The Company shall at all times provide a transfer agent and
registrar with respect to its Common Stock.

                  j. If reasonably requested by the Investor,  the Company shall
(i)  immediately  incorporate  in  a  prospectus  supplement  or  post-effective
amendment such  information as the Investor  believes should be included therein
relating to the sale and  distribution  of  Registrable  Securities,  including,
without  limitation,  information  with  respect  to the  number of  Registrable
Securities  being sold,  the  purchase  price being paid  therefor and any other
terms of the  offering of the  Registrable

                                      -4-
<PAGE>

Securities;  (ii) make all required  filings of such  prospectus  supplement  or
post-effective  amendment as soon as notified of the matters to be  incorporated
in such prospectus supplement or post-effective  amendment; and (iii) supplement
or make amendments to any registration statement.

                  k. The Company shall use its reasonable  best efforts to cause
the  Registrable   Securities  covered  by  any  registration  statement  to  be
registered with or approved by such other  governmental  agencies or authorities
as  may  be  necessary  to  consummate  the  disposition  of  such   Registrable
Securities.

                  l. Within one (1) Trading Day after any registration statement
which includes the Registrable  Securities is ordered  effective by the SEC, the
Company shall deliver, and shall cause legal counsel for the Company to deliver,
to the  transfer  agent  for such  Registrable  Securities  (with  copies to the
Investor)  confirmation  that  such  registration  statement  has been  declared
effective by the SEC in the form attached hereto as Exhibit A.

                  m.  The  Company  shall  take  all  other  reasonable  actions
reasonably  requested by the Investor to expedite and facilitate  disposition by
the Investor of Registrable Securities pursuant to any registration statement.

         4.       OBLIGATIONS OF THE INVESTOR.
                  ---------------------------

                  a. The  Company  shall  notify the  Investor in writing of the
information the Company reasonably requires from the Investor in connection with
any registration statement hereunder.  The Investor shall furnish to the Company
such information regarding itself, the Registrable Securities held by it and the
intended method of disposition of the Registrable Securities held by it as shall
be reasonably required to effect the registration of such Registrable Securities
and shall execute such  documents in connection  with such  registration  as the
Company may reasonably request.

                  b. The  Investor  agrees  to  cooperate  with the  Company  as
reasonably  requested  by the Company in  connection  with the  preparation  and
filing of any registration statement hereunder.

                  c. The Investor  agrees that,  upon receipt of any notice from
the  Company of the  happening  of any event or  existence  of facts of the kind
described  in Section  3(f) or the first  sentence of 3(e),  the  Investor  will
immediately  discontinue  disposition of Registrable  Securities pursuant to any
registration   statement(s)  covering  such  Registrable  Securities  until  the
Investor's  receipt of the  copies of the  supplemented  or  amended  prospectus
contemplated  by Section  3(f) or the first  sentence  of 3(e).  Notwithstanding
anything to the contrary, the Company shall cause its transfer agent to promptly
deliver shares of Common Stock without any restrictive legend in accordance with
the terms of the Purchase  Agreement in connection  with any sale of Registrable
Securities  with  respect to which an Investor  has entered  into a contract for
sale  prior to the  Investor's  receipt  of a notice  from  the  Company  of the
happening  of any  event of the kind  described  in  Section  3(f) or the  first
sentence of 3(e) and for which the Investor has not yet settled.

         5.       EXPENSES OF REGISTRATION.
                  ------------------------

                  All  reasonable  expenses,   other  than  sales  or  brokerage
commissions  and  legal  fees and  disbursements  of  counsel  to the  Investor,
incurred in connection with registrations, filings or qualifications pursuant to
Sections 2 and 3, including,  without limitation, all registration,  listing and

                                      -5-
<PAGE>

qualifications fees, printers and accounting fees, and fees and disbursements of
counsel for the Company, shall be paid by the Company.

         6.       INDEMNIFICATION
                  ---------------

                  a. To the fullest extent  permitted by law, the Company shall,
and hereby does, indemnify,  hold harmless and defend the Investor, each Person,
if any,  who controls  the  Investor,  the  members,  the  directors,  officers,
partners, employees, agents, representatives of the Investor and each Person, if
any,  who  controls  the  Investor  within  the  meaning  of the 1933 Act or the
Securities  Exchange  Act of  1934,  as  amended  (the  "1934  Act")  (each,  an
"Indemnified  Person"),  against  any  losses,  claims,  damages,   liabilities,
judgments,  fines,  penalties,  charges, costs, attorneys' fees, amounts paid in
settlement or expenses, joint or several,  (collectively,  "Claims") incurred in
investigating,   preparing  or  defending  any  action,  claim,  suit,  inquiry,
proceeding,  investigation  or appeal taken from the  foregoing by or before any
court or governmental,  administrative or other regulatory  agency,  body or the
SEC,  whether pending or threatened,  whether or not an indemnified  party is or
may be a party thereto ("Indemnified  Damages"), to which any of them may become
subject insofar as such Claims (or actions or proceedings,  whether commenced or
threatened,  in respect  thereof) arise out of or are based upon: (i) any untrue
statement or alleged  untrue  statement of a material  fact in the  Registration
Statement,  any  New  Registration  Statement  or any  post-effective  amendment
thereto  or in any  filing  made in  connection  with the  qualification  of the
offering  under the securities or other "blue sky" laws of any  jurisdiction  in
which Registrable Securities are offered ("Blue Sky Filing"), or the omission or
alleged  omission  to state a material  fact  required  to be stated  therein or
necessary  to make the  statements  therein  not  misleading,  (ii)  any  untrue
statement  or alleged  untrue  statement  of a material  fact  contained  in any
preliminary  prospectus if used prior to the effective date of such registration
statement, or contained in the final prospectus (as amended or supplemented,  if
the Company files any amendment  thereof or supplement  thereto with the SEC) or
the omission or alleged omission to state therein any material fact necessary to
make the statements made therein,  in light of the circumstances under which the
statements  therein were made,  not  misleading,  (iii) any violation or alleged
violation  by the  Company  of the  1933  Act,  the 1934  Act,  any  other  law,
including,  without  limitation,  any  state  securities  law,  or any  rule  or
regulation  thereunder  relating  to  the  offer  or  sale  of  the  Registrable
Securities  pursuant  to the  Registration  Statement  or any  New  Registration
Statement or (iv) any material  violation of this  Agreement (the matters in the
foregoing  clauses (i)  through  (iv) being,  collectively,  "Violations").  The
Company shall, subject to Section 6(d) reimburse each Indemnified Person for any
legal fees or other  expenses  reasonably  incurred by them in  connection  with
investigating  or  defending  any such  Claim.  Notwithstanding  anything to the
contrary  contained  herein,  the  indemnification  agreement  contained in this
Section 6(a):  (i) shall not apply to a Claim by an  Indemnified  Person arising
out of or based upon a Violation which occurs in reliance upon and in conformity
with information  furnished in writing to the Company by such Indemnified Person
expressly  for  use in  connection  with  the  preparation  of the  Registration
Statement,  any New  Registration  Statement  or any such  amendment  thereof or
supplement  thereto, if such prospectus was timely made available by the Company
pursuant to Section 3(c) or Section 3(e);  (ii) with respect to any  preliminary
prospectus,  shall not inure to the benefit of any Indemnified  Person from whom
the person  asserting a Claim  purchased  the  Registrable  Securities  that are
offered for sale by the preliminary  prospectus (or to the benefit of any person
controlling  such person) if the untrue  statement or omission of material  fact
contained in the preliminary prospectus was corrected in the prospectus, as then
amended or  supplemented,  if such  prospectus  was timely made available by the
Company pursuant to Section 3(c) or Section 3(e), and the Indemnified Person was
promptly advised in writing not to use the incorrect prospectus prior to the use
giving rise to a violation and such  Indemnified  Person,  notwithstanding  such
advice,  used it; (iii) shall not be available to the extent such Claim is based
on a  failure  of the  Investor  to  deliver  or to  cause to be  delivered  the
prospectus  made  available by the Company,  if such  prospectus was

                                      -6-
<PAGE>

timely made  available by the Company  pursuant to Section 3(c) or Section 3(e);
and (iv)  shall not apply to  amounts  paid in  settlement  of any Claim if such
settlement is effected  without the prior written consent of the Company,  which
consent shall not be unreasonably withheld.  Such indemnity shall remain in full
force and effect  regardless  of any  investigation  made by or on behalf of the
Indemnified Person and shall survive the transfer of the Registrable  Securities
by the Investor pursuant to Section 9.

                  b. In connection  with the  Registration  Statement or any New
Registration  Statement,  the Investor shall, and hereby does,  indemnify,  hold
harmless  and defend,  to the same extent and in the same manner as is set forth
in Section 6(a), the Company,  each of its  directors,  each of its officers who
signs the Registration Statement or any New Registration Statement, each Person,
if any, who controls the Company  within the meaning of the 1933 Act or the 1934
Act  (collectively  and together with an  Indemnified  Person,  an  "Indemnified
Party"),  against  any  Claim or  Indemnified  Damages  to which any of them may
become subject,  under the 1933 Act, the 1934 Act or otherwise,  insofar as such
Claim or Indemnified  Damages arise out of or are based upon any  Violation,  in
each case to the extent,  and only to the extent,  that such Violation occurs in
reliance  upon and in  conformity  with  written  information  furnished  to the
Company by the Investor  expressly for use in connection with such  registration
statement;  and,  subject to Section 6(d), the Investor will reimburse any legal
or other expenses  reasonably  incurred by them in connection with investigating
or defending any such Claim;  provided,  however,  that the indemnity  agreement
contained in this Section 6(b) and the  agreement  with respect to  contribution
contained  in Section 7 shall not apply to  amounts  paid in  settlement  of any
Claim if such  settlement is effected  without the prior written  consent of the
Investor, which consent shall not be unreasonably withheld;  provided,  further,
however, that the Investor shall be liable under this Section 6(b) for only that
amount of a Claim or Indemnified  Damages as does not exceed the net proceeds to
the Investor as a result of the sale of Registrable  Securities pursuant to such
registration  statement.  Such  indemnity  shall remain in full force and effect
regardless of any  investigation  made by or on behalf of such Indemnified Party
and shall  survive the transfer of the  Registrable  Securities  by the Investor
pursuant to Section 9.

                  c.  Promptly  after  receipt  by  an  Indemnified   Person  or
Indemnified  Party  under this  Section 6 of notice of the  commencement  of any
action or proceeding (including any governmental action or proceeding) involving
a Claim,  such  Indemnified  Person or  Indemnified  Party shall,  if a Claim in
respect thereof is to be made against any indemnifying  party under this Section
6,  deliver  to the  indemnifying  party a written  notice  of the  commencement
thereof, and the indemnifying party shall have the right to participate in, and,
to the  extent  the  indemnifying  party so  desires,  jointly  with  any  other
indemnifying party similarly  noticed,  to assume control of the defense thereof
with counsel mutually satisfactory to the indemnifying party and the Indemnified
Person or the Indemnified Party, as the case may be; provided,  however, that an
Indemnified  Person or Indemnified  Party shall have the right to retain its own
counsel with the fees and expenses to be paid by the indemnifying  party, if, in
the  reasonable  opinion of counsel  retained  by the  indemnifying  party,  the
representation  by such counsel of the Indemnified  Person or Indemnified  Party
and the  indemnifying  party would be  inappropriate  due to actual or potential
differing interests between such Indemnified Person or Indemnified Party and any
other party  represented  by such counsel in such  proceeding.  The  Indemnified
Party or Indemnified Person shall cooperate fully with the indemnifying party in
connection  with any  negotiation  or defense of any such action or claim by the
indemnifying  party and shall furnish to the indemnifying  party all information
reasonably  available  to the  Indemnified  Party or  Indemnified  Person  which
relates  to such  action  or  claim.  The  indemnifying  party  shall  keep  the
Indemnified  Party or  Indemnified  Person fully apprised at all times as to the
status of the defense or any settlement  negotiations  with respect thereto.  No
indemnifying  party shall be liable for any  settlement of any action,  claim or
proceeding  effected without its written consent,  provided,  however,  that the
indemnifying  party shall not  unreasonably

                                      -7-
<PAGE>

withhold,  delay or condition its consent. No indemnifying party shall,  without
the consent of the Indemnified Party or Indemnified Person,  consent to entry of
any judgment or enter into any  settlement  or other  compromise  which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party or Indemnified  Person of a release from all liability
in respect to such claim or litigation.  Following  indemnification  as provided
for hereunder,  the indemnifying  party shall be subrogated to all rights of the
Indemnified Party or Indemnified Person with respect to all third parties, firms
or corporations  relating to the matter for which indemnification has been made.
The  failure  to  deliver  written  notice to the  indemnifying  party  within a
reasonable  time of the  commencement  of any such action shall not relieve such
indemnifying  party of any liability to the  Indemnified  Person or  Indemnified
Party under this Section 6, except to the extent that the indemnifying  party is
prejudiced in its ability to defend such action.

                  d. The  indemnification  required  by this  Section 6 shall be
made by  periodic  payments  of the  amount  thereof  during  the  course of the
investigation or defense,  as and when bills are received or Indemnified Damages
are incurred.

                  e.  The  indemnity  agreements  contained  herein  shall be in
addition to (i) any cause of action or similar right of the Indemnified Party or
Indemnified  Person  against  the  indemnifying  party or  others,  and (ii) any
liabilities the indemnifying party may be subject to pursuant to the law.

         7.       CONTRIBUTION.
                  ------------

                  To the extent any  indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying  party agrees to make the maximum
contribution  with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no seller of Registrable  Securities guilty of fraudulent  misrepresentation
(within  the  meaning of Section  11(f) of the 1933 Act)  shall be  entitled  to
contribution  from any seller of  Registrable  Securities  who was not guilty of
fraudulent misrepresentation; and (ii) contribution by any seller of Registrable
Securities shall be limited in amount to the net amount of proceeds  received by
such seller from the sale of such Registrable Securities.

         8.       REPORTS AND DISCLOSURE UNDER THE SECURITIES ACTS.

                  With a view to making  available  to the Investor the benefits

Company agrees to:

the Company remains subject to such  requirements and the filing of such reports
and other documents is required for the applicable provisions of Rule 144; and

                  c.  furnish  to the  Investor  so  long as the  Investor  owns
Registrable  Securities,  promptly upon request,  (i) a written statement by the
Company that it has complied with the reporting and or disclosure  provisions of
Rule 144, the 1933 Act and the 1934 Act,  (ii) a copy of the most recent

action  or  proceeding,  any  claim  that it is not  personally  subject  to the

improper.  Each party hereby  irrevocably waives personal service of process and
consents  to process  being  served in any such suit,  action or  proceeding  by

If any  provision of this  Agreement  shall be invalid or  unenforceable  in any
jurisdiction,  such invalidity or unenforceability shall not affect the validity

jurisdiction.  EACH PARTY HEREBY  IRREVOCABLY  WAIVES ANY RIGHT IT MAY HAVE, AND

Re: [__________]

Ladies and Gentlemen:

          We are counsel to UNIGENE  LABORATORIES,  INC., a Delaware corporation
(the  "Company"),  and have  represented  the  Company in  connection  with that
certain Common Stock Purchase Agreement (the "Purchase  Agreement") entered into
by and among the Company and Fusion Capital Fund II, LLC (the "Holder") pursuant
to which the  Company has agreed to issue to the Holder up to Twenty One Million
Dollars  ($21,000,000)  of the Company's Common Stock, par value $0.01 per share
(the "Common  Stock") (the "Purchase  Shares"),  in accordance with the terms of
the Purchase Agreement, and (ii) the Company issued to the Holder _______ shares
of Common Stock (the "Commitment  Shares").  Pursuant to the Purchase Agreement,
the Company  also has entered  into a  Registration  Rights  Agreement  with the
Holder  (the  "Registration  Rights  Agreement")  pursuant  to which the Company
agreed,  among other things,  to register the Purchase Shares and the Commitment
Shares  under the  Securities  Act of 1933,  as  amended  (the "1933  Act").  In
connection with the Company's  obligations under the Purchase  Agreement and the
Registration   Rights  Agreement,   on   _____________,   the  Company  filed  a
Registration   Statement  (File  No.   333-_____________)   (the   "Registration
Statement") with the Securities and Exchange  Commission (the "SEC") relating to
the sale of the Purchase Shares and the Commitment Shares.

          In connection  with the foregoing,  we advise you that a member of the
SEC's  staff has  advised  us by  telephone  that the SEC has  entered  an order
declaring the Registration Statement effective under the 1933 Act at [ENTER TIME
OF  EFFECTIVENESS]  on [ENTER DATE OF  EFFECTIVENESS]  and we have no knowledge,
after  telephonic  inquiry of a member of the SEC's  staff,  that any stop order
suspending its  effectiveness  has been issued or that any  proceedings for that
purpose are pending  before,  or threatened by, the SEC and the Purchase  Shares
and the Commitment  Shares are available for sale under the 1933 Act pursuant to
the Registration Statement.

          The Buyer has confirmed it shall comply with all  securities  laws and
regulations   applicable  to  it  including   applicable   prospectus   delivery
requirements upon sale of the Commitment Shares or the Purchase Shares.

                                            Very truly yours,
                                            [Company Counsel]

be substituted therefor in corrected form with the same force and effect as if
originally filed in the corrected form and, irrespective of the date or dates of
the actual execution and/or delivery thereof, such substitute document or
instrument shall be deemed to have been executed and/or delivered as of the date
or dates required with respect to the document or instrument for which it is
substituted.  Anything in this Indenture to the contrary notwithstanding, if any
such corrective document or instrument indicates that action has been taken by
or at the request of the Company that could not have been taken had the original
document or instrument not contained such error or omission, the action so taken
shall not be invalidated or otherwise rendered ineffective but shall be and
remain in full force and effect, except to the extent that such action was a
result of willful misconduct or bad faith.  Without limiting the generality of

other Outstanding Securities, except as aforesaid.

     Section 104.  Acts of Holders; Record Dates.

     (1)  Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by or pursuant to this Indenture to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent duly
appointed in writing. Any request, demand, authorization, direction, notice,
consent, waiver or other action provided in or pursuant to this Indenture to be
given or taken by Holders of Securities of such series may, alternatively, be
embodied in and evidenced by the record of Holders of Securities of such series
voting in favor thereof, either in person or by proxies duly appointed in
writing, at any meeting of Holders of Securities of such series duly called and
held in accordance with the provisions of Article Fourteen or a combination of
such instruments and any such record. Except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
or record or both are delivered to the Trustee and, where it is hereby expressly
required, to the Company. Such instrument or instruments and any such record
(and the action embodied therein and evidenced thereby) are herein sometimes
referred to as the "Act" of the Holders signing such instrument or instruments
or so voting at any such meeting. Proof of execution of any such instrument or
of a writing appointing any such agent, or of the holding by any Person of a
Security, shall be sufficient for any purpose of this Indenture and (subject to
Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee and
the Company and any agent of the Trustee or the Company, if made in the manner
provided in this Section. The record of any meeting of Holders of Securities
shall be proved in the manner provided in Section 1406.

     Without limiting the generality of this Section 104, unless otherwise
provided in or pursuant to this Indenture, a Holder, including a U.S. Depositary
that is a Holder of a Global Security, may make, give or take, by a proxy, or
proxies, duly appointed in writing, any request, demand, authorization,
direction, notice, consent, waiver or other Act provided in or pursuant to

                                       16
<PAGE>

this Indenture or the Securities to be made, given or taken by Holders, and a
U.S. Depositary that is a Holder of a Global Security may provide its proxy or
proxies to the direct or indirect participants therein or the beneficial owners
of interests in any such Global Security through such U.S. Depositary's standing
instructions and customary practices.

     (2)  The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems sufficient and in accordance with such reasonable rules as the Trustee may
determine; and the Trustee may in any instance require further proof with
respect to any of the matters referred to in this Section.

     (3)  The ownership, principal amount and serial numbers of Registered
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, shall be proved by the Security Register.

     (4)  The ownership, principal amount and serial numbers of Bearer
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, may be proved by the production of such
Bearer Securities or by a certificate executed, as depositary, by any trust
company, bank, banker or other depositary reasonably acceptable to the Company,
wherever situated, if such certificate shall be deemed by the Company and the
Trustee to be satisfactory, showing that at the date therein mentioned such
Person had on deposit with such depositary, or exhibited to it, the Bearer
Securities therein described; or such facts may be proved by the certificate or
affidavit of the Person holding such Bearer Securities, if such certificate or
affidavit is deemed by the Company and the Trustee to be satisfactory. The
Trustee and the Company may assume that such ownership of any Bearer Security
continues until (A) another certificate or affidavit bearing a later date issued
in respect of the same Bearer Security is produced, or (B) such Bearer Security
is produced to the Trustee by some other Person, or (C) such Bearer Security is
surrendered in exchange for a Registered Security, or (D) such Bearer Security
is no longer Outstanding. The ownership, principal amount and serial numbers of
Bearer Securities held by the Person so executing such instrument or writing and
the date of the commencement and the date of the termination of holding the same
may also be proved in any other manner which the Company and the Trustee deem
sufficient.

     (5)  Any request, demand, authorization, direction, notice, consent, waiver
or other Act by the Holder of any Security shall bind every future Holder of the
same Security and the Holder of every Security issued upon the registration of
transfer thereof or in exchange therefor or in lieu thereof in respect of
anything done or suffered to be done by the Trustee, any Security Registrar, any
Paying Agent or the Company in reliance thereon, whether or not notation of such
Act is made upon such Security.

     The Company may set any day as a record date for the purpose of determining
the Holders of Outstanding Registered Securities of any series entitled to give,
make or take any request, demand, authorization, direction, notice, consent,
waiver or other action provided or permitted by this Indenture to be given, made
or taken by Holders of Securities of such series; provided that the Company may
not set a record date for, and the provisions of this paragraph shall not apply
with respect to, the giving or making of any notice, declaration, request or
direction referred to in the

                                       17
<PAGE>

next paragraph. If any record date is set pursuant to this paragraph, the
Holders of Outstanding Registered Securities of the relevant series on such
record date, and no other Holders, shall be entitled to take or revoke the
relevant action, whether or not such Holders remain Holders after such record
date; provided that no such action shall be effective hereunder unless taken on
or prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Securities of such series on such record date. Nothing in
this paragraph shall be construed to prevent the Company from setting a new
record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding
Securities of the relevant series on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Company, at its own
expense, shall cause notice of such record date, the proposed action by Holders
and the applicable Expiration Date to be given to the Trustee in writing and to
each Holder of Securities of the relevant series in the manner set forth in
Section 106.

     The Trustee may set any day as a record date for the purpose of determining
the Holders of Outstanding Registered Securities of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (4) any direction referred to in
Section 512, in each case with respect to Securities of such series.  If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Registered Securities of such series on such record date, and no other Holders,
shall be entitled to join in such notice, declaration, request or direction or
to revoke the same, whether or not such Holders remain Holders after such record
date; provided that no such action shall be effective hereunder unless taken on
or prior to the applicable Expiration Date by Holders of the requisite principal
amount of Outstanding Securities of such series on such record date.  Nothing in
this paragraph shall be construed to prevent the Trustee from setting a new
record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be canceled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of Outstanding
Securities of the relevant series on the date such action is taken. Promptly
after any record date is set pursuant to this paragraph, the Trustee, at the
Company's expense, shall cause notice of such record date, the proposed action
by Holders and the applicable Expiration Date to be sent to the Company in
writing and to each Holder of Securities of the relevant series in the manner
set forth in Section 106.

     With respect to any record date set pursuant to this Section, the party
hereto that sets such record dates may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of Registered Securities of the relevant series in the manner set
forth in Section 106, on or prior to the existing Expiration Date.  If an
Expiration Date is not designated with respect to any record date set pursuant
to this Section, the party hereto that sets such record date shall be deemed to
have initially designated the 180th day after such record date as the Expiration

                                       18
<PAGE>

Date with respect thereto, subject to its right to change the Expiration Date as
provided in this paragraph.  Notwithstanding the foregoing, no Expiration Date
shall be later than the 180th day after the applicable record date.

     Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Security may do so with regard to
all or any part of the principal amount of such Security or by one or more duly
appointed agents each of which may do so pursuant to such appointment with
regard to all or any part of such principal amount.

     Section 105.  Notices, Etc. To Trustee and Company.

     Any request, demand, authorization, direction, notice, consent, waiver or
other Act of Holders or other document provided or permitted by this Indenture
to be made upon, given or furnished to, or filed with,

     (1)  the Trustee by any Holder or the Company shall be sufficient for every
          purpose hereunder if made, given, furnished or filed in writing to or
          with the Trustee at its Corporate Trust Office, Attention: Capital
          Markets Fiduciary Services, or

     (2)  the Company by the Trustee or any Holder shall be sufficient for every
          purpose hereunder (unless otherwise herein expressly provided) if in
          writing and mailed, first-class postage prepaid, to the Company
          addressed to the attention of its Treasurer at the address of its
          principal office specified in the first paragraph of this instrument
          or at any other address previously furnished in writing to the Trustee
          by the Company.

     Section 106.  Notice to Holders of Securities; Waiver.

     Except as otherwise expressly provided in or pursuant to this Indenture,
where this Indenture provides for notice to Holders of Securities of any event,

     (1)  such notice shall be sufficiently given to Holders of Registered
          Securities if in writing and mailed, first-class postage prepaid, to
          each Holder of a Registered Security affected by such event, at his
          address as it appears in the Security Register, not later than the
          latest date, and not earlier than the earliest date, prescribed for
          the giving of such notice; and

     (2)  such notice shall be sufficiently given to Holders of Bearer
          Securities, if any, if published in an Authorized Newspaper in The
          City of New York and, if such Securities are then listed on any stock
          exchange outside the United States, in an Authorized Newspaper in such
          city as the Company shall advise the Trustee that such stock exchange
          so requires, on a Business Day at least twice, the first such
          publication to be not earlier than the earliest date and the second
          such publication not later than the latest date prescribed for the
          giving of such notice.

                                       19
<PAGE>

     In any case where notice to Holders of Registered Securities is given by
mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder of a Registered Security shall affect the
sufficiency of such notice with respect to other Holders of Registered
Securities or the sufficiency of any notice to Holders of Bearer Securities
given as provided herein.  Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided.  In
the case by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder.

     In case by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any notice to Holders of Bearer Securities as provided
above, then such notification to Holders of Bearer Securities as shall be given
with the approval of the Trustee shall constitute sufficient notice to such
Holders for every purpose hereunder. Neither failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Holders of Securities shall be filed with the Trustee, but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

     Section 107.  Language of Notices.

  Any request, demand, authorization, direction, notice, consent, election or
waiver required or permitted under this Indenture shall be in the English
language, except that, if the Company so elects, any published notice may be in
an official language of the country of publication.

     Section 108.  Conflict with Trust Indenture Act.

     If any provision hereof limits, qualifies or conflicts with any duties
under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control.  If any provision
of this Indenture modifies or excludes any provision of the Trust Indenture Act
which may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified or to be excluded, as the case may be.

     Section 109.  Effect of Headings and Table of Contents.

be invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired
thereby.

     Section 112.  Benefits of Indenture.

shall give to any Person, other than the parties hereto, any Security Registrar,
any Paying Agent and their successors hereunder, the holders of Senior
Indebtedness and the Holders of Securities or Coupons, any benefit or any legal
or equitable right, remedy or claim under this Indenture.

     Section 113.  Governing Law.

     This Indenture, the Securities and any Coupons shall be governed by and
construed in accordance with the laws of the State of New York applicable to
agreements made or instruments entered into and, in each case, performed in said
State, without regard to conflicts of laws principles thereof.

     Section 114.  Legal Holidays.

     Unless otherwise specified in or pursuant to this Indenture or any
Securities, in any case where any Interest Payment Date, Redemption Date,
Repayment Date, Stated Maturity or Maturity of any Security shall be a Legal
Holiday at any Place of Payment, then (notwithstanding any other provision of
this Indenture, any Security or any Coupon other than a provision in any
Security or Coupon that specifically states that such provision shall apply in
lieu hereof) payment need not be made at such Place of Payment on such date, but
such payment may be made on the next succeeding day that is a Business Day at
such Place of Payment with the same force and effect as if made on the Interest

Maturity, and no interest shall accrue on the amount payable on such date or at
such time for the period from and after such Interest Payment Date, Redemption
Date, Repayment Date, Stated Maturity, Maturity, as the case may be, to the next

          which such Securities shall be redeemed or purchased, in whole or in

          Dollars or in a Foreign Currency other than that in which such
          Securities are stated t be payable, the date or dates on which, the
          period or periods within which, and the other terms and conditions
          upon which, such election may be made, and the time and manner of
          determining the exchange rate between the Currency in which such
          Securities are stated to be payable and the Currency in which such
          Securities or any of them are to be paid pursuant to such election,
          and any deletions from or modifications of or additions to the terms
          of this Indenture to provide for or to facilitate the issuance of
          Securities denominated or payable, at the election of the Company or a
          Holder thereof or otherwise, in a Foreign Currency;

     (17) whether the amount of payments of principal of, any premium or
          interest on or any Additional Amounts with respect to such Securities
          may be determined with reference to an index, formula or other method
          or methods (which index, formula or method or methods may be based,
          without limitation, on one or more Currencies, commodities, equity

     (18) any deletions from, modifications of or additions to the Events of

     (19) if either or both of Section 402(2) relating to defeasance or Section
          402(3) relating to covenant defeasance shall not be applicable to the
          Securities of such series, or any covenants relating to the Securities
          of such series which shall be subject to covenant defeasance, and any
          deletions from, or modifications or additions to, the provisions of
          Article Four in respect of the Securities of such series;

     (20) if any of such Securities are to be issuable upon the exercise of
          warrants, and the time, manner and place for such Securities to be

<PAGE>

     (21) if any of such Securities are to be issuable in global form and are to
          be issuable in definitive form (whether upon original issue or upon
          exchange of a temporary Security) only upon receipt of certain
          certificates or other documents or satisfaction of other conditions,
          then the form and terms of such certificates, documents or conditions;

     (22) if there is more than one Trustee, the identity of the Trustee  and,
          if not the Trustee, the identity of each Security Registrar, Paying
          Agent or Authenticating Agent with respect to such Securities;

     (23) the Person to whom any interest on a Security of the series shall be
          payable, if other than the Person in whose name that Security (or one
          or more Predecessor Securities) is registered at the close of business
          on the Regular Record Date for such interest;

     (24) any other terms of such Securities and any deletions from or
          modifications or additions to this Indenture in respect of such
          Securities.

     All Securities of any one series and all Coupons, if any, appertaining to
Bearer Securities of such series shall be substantially identical except as to
Currency of payments due thereunder, denomination and the rate of interest, or
method of determining the rate of interest, if any, Maturity, and the date from
which interest, if any, shall accrue and except as may otherwise be provided by
the Company in or pursuant to the Company Resolution and set forth in, or
determined in the manner provided, in the Officers' Certificate or in any
indenture or indentures supplemental hereto pertaining to such series of
Securities.  The terms of the Securities of any series may provide, without
limitation, that the Securities shall be authenticated and delivered by the
Trustee on original issue from time to time upon telephonic or written order of
persons designated in the Officers' Certificate or supplemental indenture
(telephonic instructions to be promptly confirmed in writing by such person) and
that such persons are authorized to determine, consistent with such Officers'
Certificate or any applicable supplemental indenture, such terms and conditions
of the Securities of such series as are specified in such Officers' Certificate
or supplemental indenture. All Securities of any one series need not be issued
at the same time and, unless otherwise so provided by the Company, a series may
be reopened for issuances of additional Securities of such series or to
establish additional terms of such series of Securities.

     If any of the terms of the Securities of any series shall be established by
action taken by or pursuant to a Company Resolution, the Company Resolution
shall be delivered to the Trustee at or prior to the delivery of the Officers'
Certificate setting forth the terms or the manner of determining the terms of
such series.

     Section 302.  Currency; Denominations.

     Unless otherwise provided in or pursuant to this Indenture, the principal
of, any premium and interest on and any Additional Amounts with respect to the
Securities shall be payable in Dollars.  Unless otherwise provided in or
pursuant to this Indenture, Registered Securities

                                       34
<PAGE>

denominated in Dollars shall be issuable in registered form without Coupons in
denominations of $1,000 and any integral multiple thereof, and the Bearer
Securities denominated in Dollars shall be issuable in the denomination of
$5,000. Securities not denominated in Dollars shall be issuable in such
denominations as are established with respect to such Securities in or pursuant
to this Indenture.

     Section 303.  Execution, Authentication, Delivery and Dating.

     Securities shall be executed on behalf of the Company by any Officer under
its corporate seal reproduced thereon and attested by its Corporate Secretary
(provided that the Corporate Secretary shall not attest his or her own signature
as an Officer) or one of its Assistant Corporate Secretaries. Coupons shall be
executed on behalf of the Company by the Corporate Secretary or one of the
Assistant Corporate Secretaries of the Company. The signature of any of these
officers on the Securities or any Coupons appertaining thereto may be manual or
facsimile.

     Securities and any Coupons appertaining thereto bearing the manual or
facsimile signatures of individuals who were at any time the proper officers of
the Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and
delivery of such Securities or did not hold such offices at the date of such
Securities or Coupons.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities, together with any Coupons
appertaining thereto, executed by the Company, to the Trustee for authentication
and, provided that the Company Resolution and Officers' Certificate or
supplemental indenture or indentures with respect to such Securities referred to
in Section 301 and a Company Order for the authentication and delivery of such
Securities have been delivered to the Trustee, the Trustee in accordance with
the Company Order and subject to the provisions hereof and of such Securities
shall authenticate and deliver such Securities; provided, however, that in the
case of Securities offered in a Periodic Offering, the Trustee shall
authenticate and deliver such Securities from time to time in accordance with
such other procedures (including, without limitation, the receipt by the Trustee
of oral or electronic instructions from the Company or its duly authorized
agents, promptly confirmed in writing) acceptable to the Trustee as may be
specified by or pursuant to a Company Order delivered to the Trustee prior to
the time of the first authentication of Securities of such series.  If the form
or terms of the Securities of the series have been established by or pursuant to
one or more Company Resolutions as permitted by Sections 201 and 301, in
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities and any Coupons appertaining
thereto, the Trustee shall be entitled to receive, and (subject to Sections
315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in
relying upon,

     (1)  an Opinion of Counsel to the effect that:

          (a)  the form or forms and terms, or if all Securities of such series
               are not to be issued at one time, the manner of determining the
               terms of such Securities and Coupons, if any, have been
               established in conformity with the provisions of this Indenture;

                                       35
<PAGE>

          (b)  all conditions precedent provided for in this Indenture to the
               authentication and delivery of such Securities and Coupons, if
               any, appertaining thereto have been complied with and that such
               Securities, and Coupons, when completed by appropriate
               insertions, executed under the Company's corporate seal and
               attested by duly authorized officers of the Company, delivered by
               duly authorized officers of the Company to the Trustee for
               authentication pursuant to this Indenture, and authenticated and
               delivered by the Trustee and issued by the Company in the manner
               and subject to any conditions specified in such Opinion of
               Counsel, will constitute legally valid and binding obligations of
               the Company, enforceable against the Company in accordance with
               their terms, subject to bankruptcy, insolvency, reorganization,
               moratorium, arrangement, fraudulent conveyance, fraudulent
               transfer or other similar laws relating to or affecting
               creditors' rights generally, and subject to general principles of
               equity (regardless of whether enforcement is sought in a
               proceeding in equity or at law); and

          (c)  this Indenture has been qualified under the Trust Indenture Act;
               and

     (2)  an Officers' Certificate stating that, to the best knowledge of the
Persons executing such certificate, no event which is, or after notice or lapse
of time would become, an Event of Default with respect to any of the Securities
shall have occurred and be continuing.

     If all the Securities of any series are not to be issued at one time, it
shall not be necessary to deliver an Opinion of Counsel at the time of issuance
of each Security, but such opinion shall be delivered at or before the time of
issuance of the first Security of such series.  After any such first delivery,
any separate request by the Company that the Trustee authenticate Securities of
such series for original issue will be deemed to be a certification by the
Company that all conditions precedent provided for in this Indenture relating to
authentication and delivery of such Securities continue to have been complied
with.

     The Trustee shall not be required to authenticate or to cause an
Authenticating Agent to authenticate any 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 which is not reasonably acceptable to the Trustee or if the Trustee,
being advised by counsel, determines that such action may not lawfully be taken.

     With respect to Securities of a series offered in a Periodic Offering, the
Trustee may rely, as to the authorization by the Company of any of such
Securities, the form and terms thereof and the legality, validity, binding
effect and enforceability thereof, upon the Opinion of Counsel and the other
documents delivered pursuant to Sections 201 and 301 and this Section, as
applicable, in connection with the first authentication of Securities of such
series.

     Each Registered Security shall be dated the date of its authentication.
Each Bearer Security and any temporary Bearer Security in global form shall be
dated as of the date specified in or pursuant to this Indenture.

                                       36
<PAGE>

     No Security or Coupon appertaining thereto shall be entitled to any benefit
under this Indenture or be valid or obligatory for any purpose, unless there
appears on such Security a certificate of authentication substantially in the
form provided for in Section 206 or 612 executed by or on behalf of the Trustee
or by the Authenticating Agent by the manual signature of one of its authorized
officers.  Such certificate upon any Security shall be conclusive evidence, and
the only evidence, that such Security has been duly authenticated and delivered
hereunder. Except as permitted by Section 306 or 307, the Trustee shall not
authenticate and deliver any Bearer Security unless all Coupons appertaining
thereto then matured have been detached and canceled.

     Notwithstanding the foregoing, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 309, for all purposes of this Indenture such Security shall
be deemed never to have been authenticated and delivered hereunder and shall
never be entitled to the benefits of this Indenture.

     Section 304.  Temporary Securities.

     Pending the preparation of definitive Securities, the Company may execute
and deliver to the Trustee and, upon Company Order, the Trustee shall
authenticate and deliver, in the manner provided in Section 303, temporary
Securities in lieu thereof which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form or, if authorized in or pursuant to this
Indenture, in bearer form with one or more Coupons or without Coupons and with
such appropriate insertions, omissions, substitutions and other variations as
the officers of the Company executing such Securities may determine, as
conclusively evidenced by their execution of such Securities.  Such temporary
Securities may be in global form.

     Except in the case of temporary Securities in global form, which shall be
exchanged in accordance with the provisions thereof, if temporary Securities are
issued, the Company shall cause definitive Securities to be prepared without
unreasonable delay.  After the preparation of definitive Securities of the same
series and containing terms and provisions that are identical to those of any
temporary Securities, such temporary Securities shall be exchangeable for such
definitive Securities upon surrender of such temporary Securities at an Office
or Agency for such Securities, without charge to any Holder thereof.  Upon
surrender for cancellation of any one or more temporary Securities (accompanied
by any unmatured Coupons appertaining thereto), the Company shall execute and
the Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of authorized denominations of the same series
and containing identical terms and provisions; provided, however, that no
definitive Bearer Security, except as provided in or pursuant to this Indenture,
shall be delivered in exchange for a temporary Registered Security; and
provided, further, that a definitive Bearer Security shall be delivered in
exchange for a temporary Bearer Security only in compliance with the conditions
set forth in or pursuant to this Indenture.  Unless otherwise provided in or
pursuant to this Indenture with respect to a temporary Global Security, until so
exchanged the temporary Securities of any series shall in

                                       37
<PAGE>

all respects be entitled to the same benefits under this Indenture as definitive
Securities of such series.

     Section 305.  Registration, Transfer and Exchange.

     With respect to the Registered Securities of each series, if any, the
Company shall cause to be kept a register (each such register being herein
sometimes referred to as the "Security Register") at an Office or Agency for
such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series.  Such Office or Agency shall be the "Security Registrar" for that series
of Securities.  Unless otherwise specified in or pursuant to this Indenture or
the Securities, the Trustee shall be the initial Security Registrar for each
series of Securities.  The Company shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities; provided
that no such removal or replacement shall be effective until a successor
Security Registrar with respect to such series of Securities shall have been
appointed by the Company and shall have accepted such appointment. In the event
that the Trustee shall not be or shall cease to be Security Registrar with
respect to a series of Securities, it shall have the right to examine the
Security Register for such series at all reasonable times.  There shall be only
one Security Register for each series of Securities.

     Upon surrender for registration of transfer of any Registered Security of
any series at any Office or Agency for such series, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Registered Securities of the same
series denominated as authorized in or pursuant to this Indenture, of a like
aggregate principal amount bearing a number not contemporaneously outstanding
and containing identical terms and provisions.

     At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series containing
identical terms and provisions, in any authorized denominations, and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
any Office or Agency for such series.  Whenever any Registered Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Registered Securities which the Holder making the
exchange is entitled to receive.

     If provided in or pursuant to this Indenture, with respect to Securities of
any series, at the option of the Holder, Bearer Securities of such series may be
exchanged for Registered Securities of such series containing identical terms,
denominated as authorized in or pursuant to this Indenture and in the same
aggregate principal amount, upon surrender of the Bearer Securities to be
exchanged at any Office or Agency for such series, with all unmatured Coupons
and all matured Coupons in default thereto appertaining.  If the Holder of a
Bearer Security is unable to produce any such unmatured Coupon or Coupons or
matured Coupon or Coupons in default, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
and the Trustee in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the

                                       38
<PAGE>

Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless.  If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that, except as otherwise provided in Section 1002, interest
represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an Office or Agency for such series located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such Office or Agency for such series in exchange for a
Registered Security of such series and like tenor after the close of business at
such Office or Agency on (i) any Regular Record Date and before the opening of
business at such Office or Agency on the relevant Interest Payment Date, or (ii)
any Special Record Date and before the opening of business at such Office or
Agency on the related date for payment of Defaulted Interest, such Bearer
Security shall be surrendered without the Coupon relating to such Interest
Payment Date or proposed date of payment, as the case may be (or, if such Coupon
is so surrendered with such Bearer Security, such Coupon shall be returned to
the Person so surrendering the Bearer Security), and interest or Defaulted
Interest, as the case may be, shall not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of the Registered
Security issued in exchange for such Bearer Security, but shall be payable only
to the Holder of such Coupon when due in accordance with the provisions of this
Indenture.

     If provided in or pursuant to this Indenture with respect to Securities of
any series, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer Securities upon such terms and conditions as may be
provided in or pursuant to this Indenture with respect to such series.

     Whenever any Securities are surrendered for exchange as contemplated by the
immediately preceding two paragraphs, the Company shall execute, and the Trustee
shall authenticate and deliver, the Securities which the Holder making the
exchange is entitled to receive.

     Notwithstanding the foregoing, except as otherwise provided in or pursuant
to this Indenture, any Global Security shall be exchangeable for definitive
Securities only if (i) the Depositary is at any time unwilling, unable or
ineligible to continue as Depositary and a successor depositary is not appointed
by the Company within 90 days of the date the Company is so informed in writing,
(ii) the Company executes and delivers to the Trustee a Company Order to the
effect that such Global Security shall be so exchangeable, or (iii) an Event of
Default has occurred and is continuing with respect to the Securities.  If the
beneficial owners of interests in a Global Security are entitled to exchange
such interests for definitive Securities as the result of an event described in
clause (i), (ii) or (iii) of the preceding sentence, then without unnecessary
delay but in any event not later than the earliest date on which such interests
may be so exchanged, the Company shall deliver to the Trustee definitive
Securities in such form and denominations as are required by or pursuant to this
Indenture, and of the same series, containing identical terms and in aggregate
principal amount equal to the principal amount of such Global Security, executed
by the Company.  On or after the earliest date on which such interests may be so
exchanged, such Global Security shall be surrendered from time to time by the
U.S. Depositary or such other Depositary as

                                       39
<PAGE>

shall be specified in the Company Order with respect thereto, and in accordance
with instructions given to the Trustee and the U.S. Depositary or such other
Depositary, as the case may be (which instructions shall be in writing but need
not be contained in or accompanied by an Officers' Certificate or be accompanied
by an Opinion of Counsel), as shall be specified in the Company Order with
respect thereto to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or in part, for definitive Securities as described above
without charge. The Trustee shall authenticate and make available for delivery,
in exchange for each portion of such surrendered Global Security, a like
aggregate principal amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such Global
Security to be exchanged, which (unless such Securities are not issuable both as
Bearer Securities and as Registered Securities, in which case the definitive
Securities exchanged for the Global Security shall be issuable only in the form
in which the Securities are issuable, as provided in or pursuant to this
Indenture) shall be in the form of Bearer Securities or Registered Securities,
or any combination thereof, as shall be specified by the beneficial owner
thereof, but subject to the satisfaction of any certification or other
requirements to the issuance of Bearer Securities; provided, however, that no
such exchanges may occur during a period beginning at the opening of business 15
days before any selection of Securities of the same series to be redeemed and
ending on the relevant Redemption Date; and provided, further, that (unless
otherwise provided in or pursuant to this Indenture) no Bearer Security
delivered in exchange for a portion of a Global Security shall be mailed or
otherwise delivered to any location in the United States. Promptly following any
such exchange in part, such Global Security shall be returned by the Trustee to
such Depositary or the U.S. Depositary, as the case may be, or such other
Depositary or U.S. Depositary referred to above in accordance with the
instructions of the Company referred to above. If a Registered Security is
issued in exchange for any portion of a Global Security after the close of
business at the Office or Agency for such Security where such exchange occurs on
or after (i) any Regular Record Date for such Security and before the opening of
business at such Office or Agency on the next Interest Payment Date, or (ii) any
Special Record Date for such Security and before the opening of business at such
Office or Agency on the related proposed date for payment of interest or
Defaulted Interest, as the case may be, interest shall not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of such Registered Security, but shall be payable on such Interest
Payment Date or proposed date for payment, as the case may be, only to the
Person to whom interest in respect of such portion of such Global Security shall
be payable in accordance with the provisions of this Indenture.

     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company evidencing the same
debt and entitling the Holders thereof to the same benefits under this Indenture
as the Securities surrendered upon such registration of transfer or exchange.

     Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar for such Security) be duly endorsed, or be accompanied by
a written instrument of transfer in form satisfactory to the Company and the
Security Registrar for such Security duly executed by the Holder thereof or his
attorney duly authorized in writing.

                                       40
<PAGE>

     No service charge shall be made for any registration of transfer or
exchange, or redemption of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge and any other
expenses (including fees and expenses of the Trustee) that may be imposed in
connection with any registration of transfer or exchange of Securities, other
than exchanges pursuant to Section 304, 905 or 1107, or upon surrender in part
of any Registered Security for conversion or exchange into Capital Stock or
other securities pursuant to its terms, in each case not involving any transfer.

     Except as otherwise provided in or pursuant to this Indenture, the Company
shall not be required (i) to issue, register the transfer of or exchange any
Securities during a period beginning at the opening of business 15 days before
the day of the selection for redemption of Securities of like tenor and the same
series under Section 1103 and ending at the close of business on the day of such
selection, or (ii) to register the transfer of or exchange any Registered
Security so selected for redemption in whole or in part, except in the case of
any Security to be redeemed in part, the portion thereof not to be redeemed, or
(iii) to exchange any Bearer Security so selected for redemption except, to the
extent provided with respect to such Bearer Security, that such Bearer Security
may be exchanged for a Registered Security of like tenor and the same series,
provided that such Registered Security shall be immediately surrendered for
redemption with written instruction for payment consistent with the provisions
of this Indenture or (iv) to issue, register the transfer of or exchange any
Security which, in accordance with its terms, has been surrendered for repayment
at the option of the Holder, except the portion, if any, of such Security not to
be so repaid.

     The provisions of Clauses (1), (2) and (3) below shall apply only to Global
Securities:

     (1)  Each Registered Global Security authenticated under this Indenture
          shall be registered in the name of the Depositary designated for such
          Global Security or a nominee thereof and delivered to such Depositary
          or a nominee thereof or custodian therefor, and each such Global
          Security shall constitute a single Security for all purposes of this
          Indenture.

     (2)  Any exchange or transfer of a Registered Global Security for other
          Securities may be made in whole or in part, and all Securities issued
          in exchange for or upon transfer of a Global Security or any portion
          thereof shall be registered in such names as the Depositary for such
          Global Security shall direct.

     (3)  Every Security authenticated and delivered upon registration of
          transfer of, or in exchange for or in lieu of, a Global Security or
          any portion thereof, whether pursuant to this Section, Section 304,
          306, 905 or 1107 or otherwise, shall be authenticated and delivered in
          the form of, and shall be, a Global Security, unless such Security is
          registered in the name of a Person other than the Depositary for such
          Global Security or a nominee thereof.

     Section 306.  Mutilated, Destroyed, Lost and Stolen Securities.

                                       41
<PAGE>

     If any mutilated Security or a Security with a mutilated Coupon
appertaining to it is surrendered to the Trustee, subject to the provisions of
this Section 306, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

     If there be delivered to the Company and to the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security or Coupon,
and (ii) such security or indemnity as may be required by them to save each of
them and any agent of either of them harmless, then, in the absence of notice to
the Company or the Trustee that such Security or Coupon has been acquired by a
bona fide purchaser, the Company shall execute and, upon the Company's request
the Trustee shall authenticate and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Security or in exchange for the
Security to which a destroyed, lost or stolen Coupon appertains with all
appurtenant Coupons not destroyed, lost or stolen, a new Security of the same
series containing identical terms and of like principal amount and bearing a
number not contemporaneously outstanding, with Coupons corresponding to the
Coupons, if any, appertaining to such destroyed, lost or stolen Security or to
the Security to which such destroyed, lost or stolen Coupon appertains.

     Notwithstanding the foregoing provisions of this Section 306, in case any
mutilated, destroyed, lost or stolen Security or Coupon has become or is about
to become due and payable, the Company in its discretion may, instead of issuing
a new Security, pay such Security or Coupon; provided, however, that payment of
principal of, any premium or interest on or any Additional Amounts with respect
to any Bearer Securities shall, except as otherwise provided in Section 1002, be
payable only at an Office or Agency for such Securities located outside the
United States and, unless otherwise provided in or pursuant to this Indenture
(including this paragraph), any interest on Bearer Securities and any Additional
Amounts with respect to such interest shall be payable only upon presentation
and surrender of the Coupons appertaining thereto.

     Upon the issuance of any new Security under this Section, 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.

     Every new Security, with any Coupons appertaining thereto issued pursuant
to this Section in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen Coupon appertains
shall constitute a separate obligation of the Company, whether or not the
destroyed, lost or stolen Security and Coupons appertaining thereto or the
destroyed, lost or stolen Coupon shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of such series and any
Coupons, if any, duly issued hereunder.

                                       42
<PAGE>

     The provisions of this Section, as amended or supplemented pursuant to this
Indenture with respect to particular Securities or generally, shall be exclusive
and shall preclude (to the extent lawful) all other rights and remedies with
respect to the replacement or payment of mutilated, destroyed, lost or stolen
Securities or Coupons.

     Section 307.  Payment of Interest and Certain Additional Amounts; Rights to
     Interest and Certain Additional Amounts Preserved.

     Unless otherwise provided in or pursuant to this Indenture, any interest on
and any Additional Amounts with respect to any Registered Security which shall
be payable, and are punctually paid or duly provided for, on any Interest
Payment Date shall be paid to the Person in whose name such Security (or one or
more Predecessor Securities) is registered as of the close of business on the
Regular Record Date for such interest.  Unless otherwise provided in or pursuant
to this Indenture, in case a Bearer Security is surrendered in exchange for a
Registered Security after the close of business at an Office or Agency for such
Security on any Regular Record Date therefor and before the opening of business
at such Office or Agency on the next succeeding Interest Payment Date therefor,
such Bearer Security shall be surrendered without the Coupon relating to such
Interest Payment Date and interest shall not be payable on such Interest Payment
Date in respect of the Registered Security issued in exchange for such Bearer
Security, but shall be payable only to the Holder of such Coupon when due in
accordance with the provisions of this Indenture.

     Unless otherwise provided in or pursuant to this Indenture, any interest on
and any Additional Amounts with respect to any Registered Security which shall
be payable, but shall not be punctually paid or duly provided for, on any
interest Payment Date for such Registered Security (herein called "Defaulted
Interest") shall forthwith cease to be payable to the Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder; and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in Clause (1) or (2) below:

     (1)  The Company may elect to make payment of any Defaulted Interest to the
          Person in whose name such Registered Security (or a Predecessor
          Security thereof) shall be 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 such Registered 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 on or prior to the date
          of the proposed payment, such money when so deposited to be held in
          trust for the benefit of the Person 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 be not more than 15 days and not 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

                                       43
<PAGE>

          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 the Holder of such Registered Security (or a
          Predecessor Security thereof) at his address as it appears in the
          Security Register not less than 10 days prior to such Special Record
          Date. The Trustee may, in its discretion, in the name and at the
          expense of the Company cause a similar notice to be published at least
          once in an Authorized Newspaper of general circulation in the Borough
          of Manhattan, The City of New York, but such publication shall not be
          a condition precedent to the establishment of 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 Person in whose name such
          Registered Security (or a Predecessor Security thereof) shall be
          registered at the close of business on such Special Record Date and
          shall no longer be payable pursuant to the following clause (2). In
          case a Bearer Security is surrendered at the Office or Agency for such
          Security in exchange for a Registered Security after the close of
          business at such Office or Agency on any Special Record Date and
          before the opening of business at such Office or Agency on the related
          proposed date for payment of Defaulted Interest, such Bearer Security
          shall be surrendered without the Coupon relating to such Defaulted
          Interest and Defaulted Interest shall not be payable on such proposed
          date of payment in respect of the Registered Security issued in
          exchange for such Bearer Security, but shall be payable only to the
          Holder of such Coupon when due in accordance with the provisions of
          this Indenture.

     (2)  The Company may make payment of any Defaulted Interest in any other
          lawful manner not inconsistent with the requirements of any securities
          exchange on which such Security 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 payment shall be deemed practicable by the Trustee.

     Unless otherwise provided in or pursuant to this Indenture or the
Securities of any particular series, at the option of the Company, interest on
Registered Securities that bear interest may be paid by mailing a check to the
address of the Person entitled thereto as such address shall appear in the
Security Register or by transfer to an account maintained by the payee with a
bank located in the United States, provided that appropriate wire transfer
instructions shall have been delivered by such payee to the Paying Agent at
least five Business Days prior to the applicable date for payment of interest.

     Subject to the foregoing provisions of this Section and Section 305, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

     Section 308.  Persons Deemed Owners.

     Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered in the
Security Register as the owner of such Registered Security for the purpose of
receiving payment of principal of, any premium and (subject to Sections 305 and
307) interest on and any Additional Amounts with respect to such Registered
Security and for all other purposes whatsoever, whether or not any payment with
respect to such Registered Security shall be overdue, and neither the Company,
the Trustee or any agent of the Company or the Trustee shall be affected by
notice to the contrary.

     The Company, the Trustee and any agent of the Company or the Trustee may
treat the bearer of any Bearer Security or the bearer of any Coupon as the
absolute owner of such Security or Coupon for the purpose of receiving payment
thereof or on account thereof and for all other purposes whatsoever, whether or
not any payment with respect to such Security or Coupon shall be overdue, and
neither the Company, the Trustee or any agent of the Company or the Trustee
shall be affected by notice to the contrary.

     No holder of any beneficial interest in any Global Security held on its
behalf by a U.S. Depositary or Depositary shall have any rights under this
Indenture with respect to such Global Security, and such U.S. Depositary or
Depositary may be treated by the Company, the Trustee, and any agent of the
Company or the Trustee as the owner of such Global Security for all purposes

whatsoever.  None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

     Section 309.  Cancellation.

     All Securities and Coupons surrendered for payment, redemption,
registration of transfer, exchange or conversion or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and Coupons, as well as
Securities and Coupons surrendered directly to the Trustee for any such purpose,
shall be canceled promptly by the Trustee.  The Company may at any time deliver
to the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and all Securities so delivered shall be canceled promptly by the
Trustee.  No Securities shall be authenticated in lieu of or in exchange for any
Securities canceled as provided in this Section, except as expressly permitted
by or pursuant to this Indenture.  All canceled Securities and Coupons held by
the Trustee shall be disposed of by the Trustee in accordance with its customary
procedures, unless by a Company Order the Company directs their return to it.

     Section 310.  Computation of Interest.

                                       45
<PAGE>

     Except as otherwise provided in or pursuant to this Indenture or in the
Securities of any series, interest on the Securities shall be computed on the
basis of a 360-day year of twelve 30-day months.

     Section 311.  CUSIP, CINS or ISIN Numbers.

     The Company in issuing the Securities may use "CUSIP", "CINS" or "ISIN"
numbers (if then generally in use), and, if so, the Trustee or the Company shall
use "CUSIP", "CINS" or "ISIN" numbers in notices of redemption or repurchase as
a convenience to Holders; provided that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption or repurchase
and that reliance may be placed only on the other identification numbers printed
on the Securities, and any such redemption or repurchase shall not be affected
by any defect in or omission of such numbers.

in such Company Order and any Coupons appertaining thereto, and the Trustee, on
receipt of a Company Order, at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture as to
such series, when

     (1)  either

       (a)  all Securities of such series theretofore authenticated and
            delivered and all Coupons appertaining thereto (other than (i)
            Coupons appertaining to Bearer Securities of such series surrendered
            in exchange for Registered Securities of such series and maturing
            after such exchange whose surrender is not required or has been
            waived as provided in Section 305, (ii) Securities and Coupons of
            such series which have been destroyed, lost or stolen and which have
            been replaced or paid as provided in Section 306, (iii) Coupons
            appertaining to Securities of such series called for redemption and

            waived as provided in Section 1106, and (iv) Securities and Coupons
            of such series for whose payment money has theretofore been

            as provided in Section 1003) have been delivered to the Trustee for
            cancellation; or

       (b)  all such Securities of such series and, in the case of (i) or (ii)
            below, any Coupons appertaining thereto not theretofore delivered to
            the Trustee for cancellation

                                       46

          (i)   have become due and payable, or

          (ii)  will become due and payable at their Stated Maturity within one
                year, or

                redemption within one year under arrangements satisfactory to
                the Trustee for the giving of notice of redemption by the
                Trustee in the name, and at the expense, of the Company, and the
                Company, in the case of (i), (ii) or (iii) above, has deposited
                or caused to be deposited with the Trustee as trust funds in
                trust for such purpose, money in the Currency in which such
                Securities are payable in an amount sufficient to pay and
                discharge the entire indebtedness on such Securities and any
                Coupons appertaining thereto not theretofore delivered to the
                Trustee for cancellation, including the principal of, any
                premium and interest on, and, to the extent that the Securities
                of such series provide for the payment of Additional Amounts
                thereon and the amount of any such Additional Amounts is at the
                time of deposit reasonably determinable by the Company (in the
                exercise by the Company of its sole and absolute discretion),
                any Additional Amounts with respect to, such Securities and any
                Coupons appertaining thereto, to the date of such deposit (in
                the case of Securities which have become due and payable) or to
                the Maturity thereof, as the case may be;

     (2)        the Company has paid or caused to be paid all other sums payable
                hereunder by the Company with respect to the Outstanding
                Securities of such series and any Coupons appertaining thereto;
                and

     (3)        the Company has delivered to the Trustee an Officers'
                Certificate and an Opinion of Counsel, each stating that all

Securities of such series as to which it is Trustee and if the other conditions
thereto are met.

     Notwithstanding the satisfaction and discharge of this Indenture with
respect to any series of Securities, the obligations of the Company to the
Trustee under Section 606 and, if money shall have been deposited with the
Trustee pursuant to subclause (b) of clause (1) of this Section, the obligations
of the Company and the Trustee with respect to the Securities of such series
under Sections 305, 307, 403, and the last paragraph of Section 1003 shall
survive.

     Section 402.  Defeasance and Covenant Defeasance.

     (1)  Unless, pursuant to Section 301, either or both of (i) defeasance of
          the Securities of or within a series under clause (2) of this Section
          402 or (ii) covenant defeasance of the Securities of or within a
          series under clause (3) of this Section 402 shall not be applicable
          with respect to the Securities of such series, then such provisions,
          together with the other provisions of this Section 402 (with such
          modifications thereto as may be specified pursuant to Section 301 with
          respect to any Securities), shall be applicable to such Securities and
          any Coupons appertaining thereto, and the Company may at its option by
          Company Resolution, at any time, with respect to such Securities and
          any Coupons appertaining thereto, elect to have Section 402(2) or
          Section 402(3) be applied to such Outstanding Securities and any
          Coupons appertaining thereto upon compliance with the conditions set
          forth below in this Section 402.

     (2)  Upon the Company's exercise of the above option applicable to this
          Section 402(2) with respect to any Securities of or within a series,
          the Company shall be deemed to have been discharged from its
          obligations with respect to such Outstanding Securities and any
          Coupons appertaining thereto on the date the conditions set forth in
          clause (4) of this Section 402 are satisfied (hereinafter,
          "defeasance").  For this purpose, such defeasance means that the
          Company shall be deemed to have paid and discharged the entire
          indebtedness represented by such Outstanding Securities and any
          Coupons appertaining thereto, which shall thereafter be deemed to be
          "Outstanding" only for the purposes of clause (5) of this Section 402
          and the other Sections of this Indenture referred to in clauses (i)
          and (ii) below, and to have satisfied all of its other obligations
          under such Securities and any Coupons appertaining thereto and this
          indenture insofar as such Securities and any Coupons appertaining
          thereto are concerned (and the Trustee, at the expense of the Company,
          shall execute proper instruments acknowledging the same), except for
          the following which shall survive until otherwise terminated or
          discharged hereunder: (i) the rights of Holders of such Outstanding
          Securities and any Coupons appertaining thereto to receive, solely
          from the trust fund described in clause (4) of this Section 402 and as
          more fully set forth in such Section, payments in respect of the
          principal of (and premium, if any) and interest, if any, on, and
          Additional Amounts, if any, with respect to, such Securities and any
          Coupons appertaining thereto when such payments are due, and any
          rights of such Holder to convert or exchange such Securities into
          Capital Stock or other securities, (ii) the obligations of the Company
          and the Trustee with respect to such Securities under Sections 305,
          306, 1002 and 1003, with respect to the payment of Additional Amounts,
          if any, on such Securities as contemplated by Section 1004 (but only
          to the extent that the Additional Amounts payable with respect to such
          Securities exceed the amount deposited in respect of such Additional
          Amounts pursuant to Section 401(4)(a) below), and with respect to any
          rights to convert or exchange such Securities into Capital Stock or
          other securities, (iii) the rights, powers, trusts,

                                       48
<PAGE>

          duties and immunities of the Trustee hereunder (including under
          Section 607) and (iv) this Section 402. The Company may exercise its
          option under this Section 402(2) notwithstanding the prior exercise of
          its option under clause (3) of this Section 402 with respect to such
          Securities and any Coupons appertaining thereto.

     (3)  Upon the Company's exercise of the above option applicable to this
          Section 402(3) with respect to any Securities of or within a series,
          the Company shall be released from any covenant applicable to such
          Securities specified pursuant to Section 301(19), with respect to such
          Outstanding Securities and any Coupons appertaining thereto on and
          after the date the conditions set forth in clause (4) of this Section
          402 are satisfied (hereinafter, "covenant defeasance"), and such
          Securities and any Coupons appertaining thereto shall thereafter be
          deemed to be not "Outstanding" for the purposes of any direction,
          waiver, consent or declaration or Act of Holders (and the consequences
          of any thereof) in connection with any such covenant, but shall
          continue to be deemed "Outstanding" for all other purposes hereunder.
          For this purpose, such covenant defeasance means that, with respect to
          such Outstanding Securities and any Coupons appertaining thereto, the
          Company may omit to comply with, and shall have no liability in
          respect of, any term, condition or limitation set forth in any such
          covenant, whether directly or indirectly, by reason of any reference
          elsewhere herein to any such covenant or by reason of reference in any
          such covenant to any other provision herein or in any other document
          and such omission to comply shall not constitute a default or an Event
          of Default under Section 501(4) or 501(7) or otherwise, as the case
          may be, but, except as specified above, the remainder of this
          Indenture and such Securities and Coupons appertaining thereto shall
          be unaffected thereby.

               Government Obligations applicable to such Securities and Coupons
               appertaining thereto (determined on the basis of the Currency in

               specified as payable at Stated Maturity) which through the
               scheduled payment of principal and interest in respect thereof in
               accordance with their terms will provide, not later than one day

               appertaining thereto, money in an amount, or (3) a combination
               thereof, in any case, in an amount, sufficient, without
               consideration of any reinvestment of such principal and interest,
               in the opinion of a nationally recognized firm of independent
               public accountants expressed in a written certification thereof
               delivered to the Trustee, to pay and discharge, and which shall
               be applied by the Trustee (or other qualifying trustee) to pay
               and discharge, (y) the principal of (and premium, if any) and
               interest, if any, on, and, to the extent that such Securities
               provide for the payment of Additional Amounts thereon and the
               amount of any such Additional Amounts is at the time of deposit
               reasonably determinable by the Company (in the exercise by the
               Company of its sole and absolute discretion), any Additional
               Amounts with respect to, such Outstanding Securities and any
               Coupons appertaining thereto to and including the Stated Maturity
               of such principal or installment of principal or interest or the
               Redemption Date established pursuant to clause (d) below, if any,
               and (z) any mandatory sinking fund payments or analogous payments
               applicable to such Outstanding Securities and any Coupons
               appertaining thereto on the day on which such payments are due
               and payable in accordance with the terms of this Indenture and of
               such Securities and any Coupons appertaining thereto.

          (b)  Such defeasance or covenant defeasance shall not result in a
               breach or violation of, or constitute a default under, this
               Indenture or any other material agreement or instrument to which
               the Company is a party or by which it is bound.

          (c)  Solely in the case of an election under clause (2) of this
               Section 402, no Event of Default or event which with notice or
               lapse of time or both would become an Event of Default with
               respect to such Securities and any Coupons appertaining thereto
               shall have occurred and be continuing on the date of such deposit
               and, with respect to defeasance only, at any time during the
               period ending on the 91st day after the date of such deposit (it
               being understood that this condition shall not be deemed
               satisfied until the expiration  of such period).

          (d)  If the Securities are to be redeemed prior to Stated Maturity
               (other than from mandatory sinking fund payments or analogous
               payments), notice of such redemption shall have been duly given
               pursuant to this Indenture or provision therefor satisfactory to
               the Trustee shall have been made.

          (e)  The Company shall have delivered to the Trustee an Officers'
               Certificate and an Opinion of Counsel, each stating that all
               conditions precedent to the defeasance or covenant defeasance
               under clause (2) or (3) of this Section 402 (as the case may be)
               have been complied with.

          (f)  Notwithstanding any other provisions of this Section 402(4), such
               defeasance or covenant defeasance shall be effected in compliance
               with any additional or

                                       50
<PAGE>

               substitute terms, conditions or limitations which may be imposed
               on the Company in connection therewith pursuant to Section 301.

     (5)  Subject to the provisions of the last paragraph of Section 1003, all
          money and Government Obligations (or other property as may be provided
          pursuant to Section 301) (including the proceeds thereof) deposited
          with the Trustee (or other qualifying trustee, collectively for
          purposes of this Section 402(5) and Section 403, the "Trustee")
          pursuant to clause (4) of Section 402 in respect of any Outstanding
          Securities of any series and any Coupons appertaining thereto shall be
          held in trust and applied by the Trustee, in accordance with the
          provisions of such Securities and any Coupons appertaining thereto and
          this Indenture, to the payment, either directly or through any Paying
          Agent (including the Company acting as its own Paying Agent) as the
          Trustee may determine, to the Holders of such Securities and any
          Coupons appertaining thereto of all sums due and to become due thereon
          in respect of principal (and premium, if any) and interest and
          Additional Amounts, if any, but such money need not be segregated from
          other funds except to the extent required by law.

     Unless otherwise specified in or pursuant to this Indenture or any
Securities, if, after a deposit referred to in Section 402(4)(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 402(4)(a) has been made in respect of such Security, or (b)
a Conversion Event occurs in respect of the Foreign Currency in which the
deposit pursuant to Section 402(4)(a) has been made, the indebtedness
represented by such Security and any Coupons appertaining thereto shall be
deemed to have been, and will be, fully discharged and satisfied through the
payment of the principal of (and premium, if any), and interest, if any, on, and
Additional Amounts, if any, with respect to, such Security as the same becomes
due out of the proceeds yielded by converting (from time to time as specified
below in the case of any such election) the amount or other property deposited
in respect of such Security into the Currency in which such Security becomes
payable as a result of such election or Conversion Event based on (x) in the
case of payments made pursuant to clause (a) above, the applicable market
exchange rate for such Currency in effect on the second Business Day prior to
each payment date, or (y) with respect to a Conversion Event, the applicable
market exchange rate for such Foreign Currency in effect (as nearly as feasible)
at the time of the Conversion Event.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge, imposed on or assessed against the Government Obligations
deposited pursuant to this Section 402 or the principal or interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of such Outstanding Securities and any Coupons
appertaining thereto.

     Anything in this Section 402 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon Company Request any
money or Government Obligations (or other property and any proceeds therefrom)
held by it as provided in clause (4) of

                                       51
<PAGE>

this Section 402 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect a defeasance or covenant defeasance, as
applicable, in accordance with this Section 402.

     Section 403.  Application of Trust Money.

     Subject to the provisions of the last paragraph of Section 1003, all money
and Government Obligations deposited with the Trustee (or other qualifying
Trustee) pursuant to Section 401 or 402 shall be held in trust and applied by
it, in accordance with the provisions of the Securities, the Coupons and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee (or other
qualifying Trustee) may determine, to the Persons entitled thereto, of the
principal, premium, interest and Additional Amounts for whose payment such money
has or Government Obligations have been deposited with or received by the
Trustee (or other qualifying Trustee); but such money and Government Obligations
need not be segregated from other funds except to the extent required by law.

     Section 404.  Qualifying Trustee.

     Any trustee appointed pursuant to Section 402 for the purpose of holding
money or Government Obligations deposited pursuant to that Section shall be
appointed under an agreement in form acceptable to the Trustee and shall provide
to the Trustee a certificate of such trustee, upon which certificate the Trustee
shall be entitled to conclusively rely, that all conditions precedent provided
for herein to the related defeasance or covenant defeasance have been complied
with. In no event shall the Trustee be liable for any acts or omissions of said
trustee.

     Section 405.  Reinstatement.

     If the Trustee (or other qualifying trustee) is unable to apply any money
or Government Obligations in accordance with Section 401 or 402, as applicable,
by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, the Company's
obligations under this Indenture, the Securities and the Coupons, if any,
appertaining thereto shall be revived and reinstated as though no deposit had
occurred pursuant to Section 401 or 402 until such time as the Trustee (or other
qualifying trustee) is permitted to apply all such money or Government
Obligations in accordance with Section 401 or 402, as applicable; provided,
however, that if the Company has made any payment of principal of or any premium
or interest on any Securities or Coupons because of the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of
such Securities or Coupons to receive such payment from the money or Government
Obligations held by the Trustee (or other qualifying trustee).

     Section 406.  Effect on Subordination Provisions.

     Unless otherwise expressly provided pursuant to Section 301 with respect to
the Securities of any series, the provisions for subordination of the Securities
set forth in Article Fifteen hereof are hereby expressly made subject to the
provisions for satisfaction and discharge set forth in Section 401 hereof and
the provisions for defeasance and covenant defeasance set forth in Section 402
hereof and, anything herein to the contrary notwithstanding, upon the
effectiveness of such satisfaction and discharge pursuant to Section 401 or any
such defeasance or covenant defeasance pursuant to Section 402 with respect to
the Securities of any series, such Securities shall thereupon cease to be so
subordinated and shall no longer be subject to the provisions of Article Fifteen
hereof and, without limitation to the foregoing, all moneys, Government
Obligations and other securities or property deposited with the Trustee (or
other qualifying trustee) in trust in connection with such satisfaction and
discharge, defeasance or covenant defeasance, as the case may be, and all
proceeds therefrom may be applied to pay the principal of, premium, if any, and
interest, if any, on, and Additional Amounts, if any, with respect to the
Securities of such series as and when the same shall become due and payable
notwithstanding the provisions of Article Fifteen.

          when such interest or such Additional Amounts become due and payable,
          and continuance of such default for a period of 60 days; or

     (2)  default in the payment of the principal of or premium, if any, on, or

     (4)  default in the performance, or breach, of any covenant or warranty of

          or nonperformance are addressed (a) elsewhere in this Section 501 or
          (b) in such Security or (ii) a covenant or warranty which has
          expressly been included in this Indenture or a Security of a series,
          whether or not by means of a supplemental indenture, solely for the
          benefit of Securities of a series other than such series), and
          continuance of such default or breach for a period of 90 days after
          there has been given, by registered or certified mail, to the Company

          least 33% in principal amount of the Outstanding Securities of such
          series a written notice specifying such default or breach and
          requiring it to be remedied and stating that such notice is a "Notice
          of Default" hereunder, unless the Trustee, or the Trustee and the
          Holders of a principal amount of Securities of such series not less
          than the principal amount of Securities the Holders of which gave such
          notice, as the case may be, shall agree in writing to an extension of
          such period prior to its expiration; provided, however, that the
          Trustee, or the Trustee and the Holders of such principal amount of
          Securities of such series, as the case may be, shall be deemed to have
          agreed to an extension of such period if corrective action is
          initiated by the Company within such period and is being diligently
          pursued; or

                                       53

     Section 502.  Acceleration of Maturity; Rescission and Annulment.

     If an Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then the Trustee or the Holders of not
less than 33% in principal amount of the Outstanding Securities of such series
may declare the principal of all the Securities of such series, or such lesser
amount as may be provided for in the Securities of such series, to be due and

                                       54
<PAGE>

payable immediately, by a notice in writing to the Company (and to the Trustee
if given by the Holders), and upon any such declaration such principal or such
lesser amount shall become immediately due and payable.

     At any time after Securities of any series have been accelerated and before
a judgment or decree for payment of the money due has been obtained by the
Trustee as hereinafter in this Article provided, the Holders of not less than a
majority in principal amount of the Outstanding Securities of such series, by
written notice to the Company and the Trustee, may rescind and annul such
declaration and its consequences if

     (1)  the Company has paid or deposited with the Trustee a sum of money
          sufficient to pay

          (a)  all overdue installments of any interest on any Securities of
               such series and any Coupons appertaining thereto and any
               Additional Amounts with respect thereto,

          (b)  the principal of and any premium on any Securities of such series
               which have become due otherwise than by such declaration of
               acceleration and any Additional Amounts with respect thereto and,
               to the extent the payment of such interest is lawful, interest
               thereon at the rate or rates borne by or provided for in such
               Securities,

          (c)  to the extent that payment of such interest is lawful, interest
               upon overdue installments of any interest and any Additional
               Amounts with respect thereto at the rate or rates borne by or
               provided for in such Securities, and

          (d)  all sums paid or advanced by the Trustee hereunder and the
               reasonable compensation, expenses, disbursements and advances of
               the Trustee, its agents and counsel and all other amounts due the
               Trustee under Section 607; and

     (2)  all Events of Default with respect to Securities of such series, other
          than the non-payment of the principal of, any premium and interest on,
          and any Additional Amounts with respect to Securities of such series
          which shall have become due solely by such declaration of
          acceleration, shall have been cured or waived as provided in Section
          513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

     Section 503.   Collection of Indebtedness and Suits for Enforcement by
     Trustee.

     The Company covenants that if

     (1)  default is made in the payment of any installment of interest on or
          any Additional Amounts payable in respect of any interest on, any
          Security when such interest or

                                       55
<PAGE>

          Additional Amounts shall have become due and payable and such default
          continues for a period of 30 days, or

     (2)  default is made in the payment of the principal of or any premium on,
          or any Additional Amounts payable in respect of the principal of or
          any premium on, any Security at its Maturity, the Company shall, upon
          demand of the Trustee, pay to the Trustee, for the benefit of the
          Holders of such Securities and any Coupons appertaining thereto, the
          whole amount of money then due and payable with respect to such
          Securities and any Coupons appertaining thereto, with interest upon
          the overdue principal, any premium and, to the extent that payment of
          such interest shall be legally enforceable, upon any overdue
          installments of interest and Additional Amounts at the rate or rates
          borne by or provided for in such Securities, and, in addition thereto,
          such further amount of money as shall be sufficient to cover the costs
          and expenses of collection, including the reasonable compensation,
          expenses, disbursements and advances of the Trustee, its agents and
          counsel and all other amounts due to the Trustee under Section 607.

     If the Company fails to pay the money it is required to pay the Trustee
pursuant to the preceding paragraph forthwith upon the demand of the Trustee,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the money so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Securities and any Coupons
appertaining thereto and collect the monies adjudged or decreed to be payable in
the manner provided by law out of the property of the Company or any other
obligor upon such Securities and any Coupons appertaining thereto, wherever
situated.

     If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the Holders of Securities of such series and any
Coupons appertaining thereto by such appropriate judicial proceedings as the
Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this
Indenture or such Securities or in aid of the exercise of any power granted
herein or therein, or to enforce any other proper remedy.

     Section 504.  Trustee May File Proofs of Claim.

     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of any overdue principal, premium, interest or
Additional Amounts) shall be entitled and empowered, by intervention in such
proceeding or otherwise, to take any and all actions authorized under the Trust

                                       56
<PAGE>

Indenture Act in order to have claims of the Holders and the Trustee allowed in
any such proceeding.  In particular, the Trustee shall be authorized

     (1)  to file and prove a claim for the whole amount, or such lesser amount
          as may be provided for in the Securities of such series, of the
          principal and any premium, interest and Additional Amounts owing and
          unpaid in respect of the Securities and any Coupons appertaining
          thereto and to file such other papers or documents as may be necessary
          or advisable in order to have the claims of the Trustee (including any
          claim for the reasonable compensation, expenses, disbursements and
          advances of the Trustee, its agents or counsel) and of the Holders of
          Securities or any Coupons allowed in such judicial proceeding, and

     (2)  to collect and receive any monies or other property payable or
          deliverable on any such claims and to distribute the same; and any
          custodian, receiver, assignee, trustee, liquidator, sequestrator or
          other similar official in any such judicial proceeding is hereby
          authorized by each Holder of Securities or any Coupons to make such
          payments to the Trustee and, in the event that the Trustee shall
          consent to the making of such payments directly to the Holders of
          Securities or any Coupons, to pay to the Trustee any amount due to it
          for the reasonable compensation, expenses, disbursements and advances

affecting the Securities or Coupons or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder of a

shall be brought in its own name as trustee of an express trust, and any
recovery or judgment, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, shall be for the ratable benefit of each and every Holder of a
Security or Coupon in respect of which such judgment has been recovered.

shall have any right to institute any proceeding, judicial or otherwise, with
respect to this Indenture, or for the appointment of a receiver or trustee, or

     (1)  such Holder has previously given written notice to the Trustee of a
          continuing Event of Default with respect to the Securities of such
          series;

     (2)  the Holders of not less than a majority in principal amount of the
          Outstanding Securities of such series shall have made written request
          to the Trustee to institute proceedings in respect of such Event of
          Default in its own name as Trustee hereunder;

     (3)  such Holder or Holders have offered to the Trustee reasonable
          indemnity against the costs, expenses and liabilities to be incurred
          in compliance with such request;

     (4)  the Trustee for 60 days after its receipt of such notice, request and
          offer of indemnity has failed to institute any such proceeding; and

     (5)  no direction inconsistent with such written request has been given to
          the Trustee during such 60-day period by the Holders of a majority in
          principal amount of the Outstanding Securities of such series; it
          being understood and intended that no one or more of such Holders
          shall have any right in any manner whatever by virtue of, or by
          availing of, any provision of this Indenture or any Security to
          affect, disturb or prejudice the rights of any other such Holders or
          Holders of Securities of any other series, or to obtain or to seek to
          obtain priority or preference over any other

                                       58
<PAGE>

          Holders or to enforce any right under this Indenture, except in the
          manner herein provided and for the equal and ratable benefit of all
          such Holders.

     Section 508.  Unconditional Right of Holders to Receive Principal and Any
     Premium, Interest and Additional Amounts.

     Notwithstanding any other provision in this Indenture, the Holder of any
Security or Coupon shall have the right, which is absolute and unconditional, to

and 307) interest on, and any Additional Amounts with respect to such Security
or such Coupon, as the case may be, on the respective Stated Maturity or
Maturities therefor specified in such Security or Coupon (or, in the case of
redemption, on the Redemption Date or, in the case of repayment at the option of
such Holder, on the Repayment Date) and to institute suit for the enforcement of
any such payment, and such right shall not be impaired without the consent of
such Holder.

determined adversely to the Trustee or to such Holder, then and in every such
case the Company, the Trustee and each such Holder shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee and each such Holder shall continue as though no such proceeding had
been instituted.

     Section 510.  Rights and Remedies Cumulative.

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities or Coupons in the last paragraph
of Section 306, no right or remedy herein conferred upon or reserved to the
Trustee or to each and every Holder of a Security or a Coupon is intended to be
exclusive of any other right or remedy, and every right and remedy, to the
extent permitted by law, shall be cumulative and in addition to every other
right and remedy given hereunder or now or hereafter existing at law or in
equity or otherwise.  The assertion or employment of any right or remedy
hereunder, or otherwise, shall not, to the extent permitted by law, prevent the
concurrent assertion or employment of any other appropriate right or remedy.

     Section 511.  Delay or Omission not Waiver.

     No delay or omission of the Trustee or of any Holder of any Security or
Coupon to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein.  Every right and remedy given by this
Article or by law to the Trustee or to any Holder of a Security or a Coupon may
be exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by such Holder, as the case may be.

     The Holders of a majority in principal amount of the Outstanding Securities
of any series 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 the Securities of
such series and any Coupons appertaining thereto, provided that

     (1)  such direction shall not be in conflict with any rule of law or with
          this Indenture or with the Securities of any series,

     (2)  the Trustee may take any other action deemed proper by the Trustee
          which is not inconsistent with such direction,

     (3)  such direction is not unduly prejudicial to the rights of the other
          Holders of Securities of such series not joining in such action, and

     (4)  subject to the provisions of Section 601, 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 would involve the Trustee in
          personal liability.

     Section 513.  Waiver of Past Defaults.

     The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series on behalf of the Holders of all the
Securities of such series and any Coupons appertaining thereto may waive any
past default hereunder with respect to such series and its consequences, except
a default

     (1)  in the payment of the principal of, any premium or interest on, or any
          Additional Amounts with respect to, any Security of such series or any
          Coupons appertaining thereto, or

     (2)  in respect of a covenant or provision hereof which under Article Nine
          cannot be modified or amended without the consent of the Holder of
          each Outstanding Security of such series affected.

     Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

     Section 514.  Waiver of Stay or Extension Laws.

     The Company covenants that (to the extent that it may lawfully do so) it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may

                                       60
<PAGE>

affect the covenants or the performance of this Indenture; and the Company
expressly waives (to the extent that it may lawfully do so) all benefit or
advantage of any such law and covenants that it will not hinder, delay or impede
the execution of any power herein granted to the Trustee, but will suffer and
permit the execution of every such power as though no such law had been enacted.

     Section 515.  Undertaking for Costs.

     All parties to this Indenture agree, and each Holder of any Security by his
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 any
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 litigant; but the provisions
of this Section 515 shall not apply to any suit instituted by the Trustee, to
any suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of Outstanding Securities of any series, or to
any suit instituted by any Holder for the enforcement of the payment of the
principal of (or premium, if any) or interest, if any, on or Additional Amounts,
if any, with respect to any Security on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date, and, in the case of repayment, on or after the
Repayment Date) or for the enforcement of the right, if any, to convert or
exchange any Security into Capital Stock or other securities in accordance with
its terms.

Trust Indenture Act.  Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers, if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it.  Whether or not therein
expressly so provided, every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

     Section 602.  Certain Rights of Trustee.

          (unless other evidence shall be herein specifically prescribed) may,
          in the absence of bad faith on its part, rely upon an Officers'
          Certificate;

     (4)  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, suffered

          or powers vested in it by or pursuant to this Indenture at the request
          or direction of any of the Holders of Securities of any series or any
          Coupons appertaining thereto pursuant to this Indenture, unless such

          Trustee, in its discretion, may make such further inquiry or
          investigation into such facts or matters as it may see fit, and, if
          the Trustee shall determine to make such further inquiry or
          investigation, it shall be entitled to examine, during business hours
          and upon reasonable notice, the books, records and premises of the

in the case of any default of the character specified in Section 501(4) with
respect to Securities of such series, no such notice to Holders shall be given

Trust Indenture Act, may otherwise deal with the Company with the same rights it
would have if it were not Trustee, Authenticating Agent, Paying Agent, Security
Registrar or such other Person.

     Section 606.  Money Held in Trust.

     (1)  to pay to the Trustee from time to time such compensation as shall be
          agreed to in writing between the Company and the Trustee for all

          claim or liability in connection with the exercise or performance of
          any of their powers or duties hereunder, except to the extent that any
          such loss, liability or expense was due to the Trustee's negligence or
          bad faith.

this Section, the Trustee shall have a lien prior to the Securities of any
series upon all property and funds held or collected by the Trustee as such,

interest on or any Additional Amounts with respect to particular Securities or
any Coupons appertaining thereto.

under any then applicable bankruptcy or insolvency law.  "Trustee" for purposes
of this Section 607 shall include any predecessor Trustee but the negligence or

this Section 607.

          or the Holders of Securities and accepted appointment in the manner
          required by Section 610, any Holder of a Security who has been a bona

          successor Trustee, without any further act, deed or conveyance, shall

          successor Trustee, such retiring Trustee, upon payment of its charges,
          shall execute and deliver an instrument transferring to such successor
          Trustee all the rights, powers and trusts of the retiring Trustee and,
          subject to Section 1003, shall duly assign, transfer and deliver to

          to the Securities of one or more (but not all) series, the Company,

          deliver an indenture supplemental hereto wherein each successor
          Trustee shall accept such appointment and which (1) shall contain such

          Securities of that or those series to which the appointment of such
          successor Trustee relates, (2) if the retiring Trustee is not retiring
          with respect to all Securities, 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

          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 notice given

          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 have no further responsibility for the exercise

          the Securities of that or those series to which the appointment of
          such successor Trustee relates other than as hereinafter expressly set
          forth, 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 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 such successor
          Trustee, such retiring Trustee, upon payment of its charges with
          respect to the Securities of that or those series to which the
          appointment of such successor relates and subject to Section 1003
          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, subject to its lien, if any, provided for
          in Section 607.

     (3)  Upon request of any Person appointed hereunder as a 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

     (4)  No Person shall accept its appointment hereunder as a successor
          Trustee unless at the time of such acceptance such successor Person
          shall be qualified under the Trust Indenture Act and eligible under
          this Article.

     Section 611.  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, shall be the successor of the Trustee hereunder,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto.  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 612.  Appointment of Authenticating Agent.

     The Trustee may appoint one or more Authenticating Agents acceptable to the
Company with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of that or
those series issued upon original issue, exchange, registration of transfer,
partial redemption or partial repayment, or pursuant to Section 306, 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.  Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent.

     Each Authenticating Agent shall be acceptable to the Company and, except as
provided in or pursuant to this Indenture, shall at all times be a corporation
that would be permitted by the Trust Indenture Act to act as trustee under an
indenture qualified under the Trust Indenture Act, is authorized under
applicable law and by its charter to act as an Authenticating Agent and has a
combined capital and surplus (computed in accordance with Section 310(a)(2) of
the Trust Indenture Act) of at least $50,000,000 and subject to supervision or
examination by Federal or State authority.  If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section, the combined capital and surplus of such Authenticating Agent
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published.  If at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect specified in this
Section.

                                       68
<PAGE>

     Any Corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any Corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any Corporation succeeding to all or substantially all of
the corporate agency or corporate trust business of an Authenticating Agent,
shall be the successor of such Authenticating Agent hereunder, provided such
Corporation shall be otherwise eligible under this Section, without the
execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and the Company.  The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and the Company.  Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall (i) mail written notice
of such appointment by first-class mail, postage prepaid, to all Holders of
Registered Securities, if any, of the series with respect to which such
Authenticating Agent shall serve, as their names and addresses appear in the
Security Register, and (ii) if Securities of the series are issued as Bearer
Securities, publish notice of such appointment at least once in an Authorized
Newspaper in the place where such successor Authenticating Agent has its
principal office if such office is located outside the United States. Any
successor Authenticating Agent, upon acceptance of its appointment hereunder,
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

     The Company agrees to pay each Authenticating Agent from time to time
reasonable compensation for its services under this Section.  If the Trustee
makes such payments, it shall be entitled to be reimbursed for such payments,
subject to the provisions of Section 607.

     The provisions of Sections 308, 604 and 605 shall be applicable to each
Authenticating Agent.

     If an Authenticating Agent is appointed with respect to one or more series
of Securities pursuant to this Section, the Securities of such series may have
endorsed thereon, in addition to or in lieu of the Trustee's certificate of
authentication, an alternate certificate of authentication in substantially the
following form:

     This is one of the Securities of the series designated therein referred to
in the within-mentioned Indenture.

     By: ______________________________________
         Authorized Signatory

     If all of the Securities of any series may not be originally issued at one
time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the
Company wishes to have Securities of such series authenticated upon original
issuance, the Trustee, if so requested in writing (which writing need not be
accompanied by or contained in an Officers' Certificate by the Company), shall
appoint in accordance with this Section and such procedures as shall be
acceptable to the Trustee an Authenticating Agent having an office in a Place of
Payment designated by the Company with respect to such series of Securities.

     Section 613.  [Conflicting Interests].

     [If the Trustee has or shall acquire a conflicting interest within the
meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture. To the extent
permitted by such Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series, [LIST OUT OTHER COMPANY DOCUMENTS PURSUANT
TO WHICH CHASE SERVES AS TRUSTEE].]

     Section 614.  Preferential Collection of Claims Against Company.

     If and when the Trustee shall be or become a creditor of the Company (or
any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

          appertaining thereto or any other Security or Coupon in any material
          respect; or

     (10) to secure the Securities; or

     (11) to make provisions with respect to conversion or exchange rights of
          Holders of Securities of any series; or

     (12) to amend or supplement any provision contained herein or in any
          supplemental indenture (which amendment or supplement may apply to one
          or more series of Securities or to one or more Securities within any
          series as specified in such supplemental indenture or indentures),
          provided that such amendment or supplement does not apply to any
          Outstanding Security issued prior to the date of such supplemental
          indenture and entitled to the benefits of such provision.

     Section 902.  Supplemental Indentures with Consent of Holders.

     With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture, by Act of said Holders delivered to the Company and the
Trustee, the Company (when authorized by or pursuant to a Company Resolution),
and the Trustee may enter into an indenture or indentures supplemental hereto
for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture or of the Securities of such
series or of modifying in any manner the rights of the Holders of Securities of
such series under this Indenture; provided, however, that no such supplemental
indenture, without the consent of the Holder of each Outstanding Security
affected thereby, shall

     (1)  change the Stated Maturity of the principal of, or any premium or
          installment of interest on or any Additional Amounts with respect to,
          any Security, or reduce the principal amount thereof or the rate (or
          modify the calculation of such rate) of interest thereon or any
          Additional Amounts with respect thereto, or any premium payable upon
          the redemption or repayment thereof or otherwise, or change the
          obligation of the Company to pay Additional Amounts pursuant to
          Section 1004, or reduce the amount of the principal of an Original
          Issue Discount Security that would be due and payable upon a
          declaration of acceleration of the Maturity thereof pursuant to
          Section 502 or the amount thereof provable in bankruptcy pursuant to
          Section 504, or change the Place of Payment, Currency in which the
          principal of, any premium or interest on, or any Additional Amounts
          with respect to any Security is payable, or impair the right to
          institute suit for the enforcement of any such payment on or after the
          Stated Maturity thereof (or,

                                       75
<PAGE>

          in the case of redemption, on or after the Redemption Date or, in the
          case of repayment at the option of the Holder, on or after the
          Repayment Date), or

     (2)  reduce the percentage in principal amount of the Outstanding
          Securities of any series, the consent of whose Holders is required for
          any such supplemental indenture, or the consent of whose Holders is
          required for any waiver of certain defaults hereunder and their
          consequences provided for in this Indenture, or reduce the
          requirements of Section 1404 for quorum or voting, or

     (3)  modify any of the provisions of Article Fifteen or the definition of
          "Senior Indebtedness" in a manner adverse to the Holders of
          Securities, or

     (4)  modify any of the provisions of this Section or Section 513, except to
          increase any such percentage or to provide that certain other
          provisions of this Indenture cannot be modified or waived without the
          consent of the Holder of each Outstanding Security affected thereby;
          provided, however, that this clause shall not be deemed to require the
          consent of any Holder with respect to changes in the references to
          "the Trustee" and concomitant changes in this Section, or the deletion
          of this proviso, in accordance with the requirements of Sections 610
          and 901(5), or

     (5)  make any change that adversely affects the right to convert or
          exchange any Security for Capital Stock or other securities in
          accordance with its terms.

     A supplemental indenture which changes or eliminates any covenant or other
provision of this Indenture which shall have been included expressly and solely
for the benefit of one or more particular series of Securities, or which
modifies the rights of the Holders of Securities of such series with respect to
such covenant or other provision, shall be deemed not to affect the rights under
this Indenture of the Holders of Securities of any other series.

     It shall not be necessary for any Act of Holders of Securities under this
Section to approve the particular form of any proposed supplemental indenture,
but it shall be sufficient if such Act shall approve the substance thereof.

     Section 903.  Execution of Supplemental Indentures.

     As a condition to executing, or accepting the additional trusts created by,
any supplemental indenture permitted by this Article or the modifications
thereby of the trust created by this Indenture, the Trustee shall be entitled to
receive, and (subject to Section 315 of the Trust Indenture Act) shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture.  The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

     Section 904.  Effect of Supplemental Indentures.

     Upon the execution of any supplemental indenture under this Article, this
Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this

                                       76
<PAGE>

Indenture for all purposes; and every Holder of a Security theretofore or
thereafter authenticated and delivered hereunder and of any Coupon appertaining
thereto shall be bound thereby.

     Section 905.  Reference in Securities to Supplemental Indentures.

     Securities of any series authenticated and delivered after the execution of
any supplemental indenture pursuant to this Article may, and shall if required
by the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture.  If the Company shall so determine,
new Securities of any series so modified as to conform, in the opinion of the
Trustee and the Company, to any such supplemental indenture may be prepared and
executed by the Company and authenticated and delivered by the Trustee in
exchange for Outstanding Securities of such series.

     Section 906.  Effect on Senior Indebtedness.

     No supplement indenture shall directly or indirectly modify or eliminate
the provisions of Article Fifteen or the definition of "Senior Indebtedness" in
any manner which might terminate or impair the subordination of the Securities
to Senior Indebtedness without the prior written consent of the Holders of the
Senior Indebtedness.

     Section 907.  Conformity with Trust Indenture Act.

     Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

COVENANTS

     Section 1001. Payment of Principal, Any Premium, Interest and Additional
     Amounts.

     The Company covenants and agrees for the benefit of the Holders of the
Securities of each series that it will duly and punctually pay the principal of,
any premium and interest on and any Additional Amounts with respect to the
Securities of such series in accordance with the terms thereof, any Coupons
appertaining thereto and this Indenture.  Any interest due on any Bearer
Security on or before the Maturity thereof, and any Additional Amounts payable
with respect to such interest, shall be payable only upon presentation and
surrender of the Coupons appertaining thereto for such interest as they
severally mature.

     Section 1002. Maintenance of Office or Agency.

     The Company shall maintain in each Place of Payment for any series of
Securities an Office or Agency where Securities of such series (but not Bearer
Securities, except as otherwise provided below, unless such Place of Payment is
located outside the United States) may be presented or surrendered for payment,
where Securities of such series may be surrendered for registration of transfer
or exchange, where Securities of such series that are convertible or
exchangeable may be surrendered for conversion or exchange, and where notices
and demands to or upon the Company in respect of the Securities of such series
relating thereto and this Indenture may be served.  If Securities of a series
are issuable as Bearer Securities, the Company shall maintain, subject to any
laws or regulations applicable thereto, an Office or Agency in a Place of
Payment for such series which is located outside the United States where
Securities of such series

                                       77
<PAGE>

and any Coupons appertaining thereto may be presented and surrendered for
payment; provided, however, that if the Securities of such series are listed on
The Stock Exchange of the United Kingdom and the Republic of Ireland or the
Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such stock exchange shall so require, the Company shall maintain a
Paying Agent in London, Luxembourg or any other required city located outside
the United States, as the case may be, so long as the Securities of such series
are listed on such exchange. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such Office or
Agency. 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, surrenders, notices and demands may be made or served at the
Corporate Trust Office of the Trustee, except that Bearer Securities of such
series and any Coupons appertaining thereto may be presented and surrendered for
payment at the place specified for the purpose with respect to such Securities
as provided in or pursuant to this Indenture, and the Company hereby appoints
the Trustee as its agent to receive all such presentations, surrenders, notices
and demands.

     Except as otherwise provided in or pursuant to this Indenture, no payment
of principal, premium, interest or Additional Amounts with respect to Bearer
Securities shall be made at any Office or Agency in the United States or by
check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, if
amounts owing with respect to any Bearer Securities shall be payable in Dollars,
payment of principal of, any premium or interest on and any Additional Amounts
with respect to any such Security may be made at the Corporate Trust Office of
the Trustee or any Office or Agency designated by the Company in the Borough of
Manhattan, The City of New York, if (but only if) payment of the full amount of
such principal, premium, interest or Additional Amounts at all offices outside
the United States maintained for such purpose by the Company in accordance with
this Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

     The Company may also from time to time designate one or more other Offices
or Agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided, however, that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an Office or Agency
in each Place of Payment for Securities of any series for such purposes.  The
Company shall give prompt written notice to the Trustee of any such designation
or rescission and of any change in the location of any such other Office or
Agency.  Unless otherwise provided in or pursuant to this Indenture, the Company
hereby designates as the Place of Payment for each series of Securities the
Borough of Manhattan, The City of New York, and initially appoints the Corporate
Trust Office of the Trustee as the Company's Office or Agency in the Borough of
Manhattan, The City of New York for such purpose.  The Company may subsequently
appoint a different Office or Agency in the Borough of Manhattan, The City of
New York for the Securities of any series.

     Section 1003.  Money for Securities Payments to be Held in Trust.

     If the Company shall at any time act as its own Paying Agent with respect
to any series of Securities, it shall, on or before each due date of the
principal of, any premium or interest on or

                                       78
<PAGE>

Additional Amounts with respect to any of the Securities of such series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum in the Currency or Currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) sufficient to pay the principal or any premium,
interest or Additional Amounts so becoming due until such sums shall be paid to
such Persons or otherwise disposed of as herein provided, and shall promptly
notify the Trustee of its action or failure so to act.

     Whenever the Company shall have one or more Paying Agents for any series of
Securities, it shall, on or prior to each due date of the principal of, any
premium or interest on or any Additional Amounts with respect to any Securities
of such series, deposit with any Paying Agent a sum (in the Currency or
Currencies described in the preceding paragraph) sufficient to pay the principal
or any premium, interest or Additional Amounts so becoming due, such sum to be
held in trust for the benefit of the Persons entitled thereto, and (unless such
Paying Agent is the Trustee) the Company will promptly notify the Trustee of its
action or failure so to act.

     The Company shall cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section, that such Paying Agent shall:

     (1)  hold all sums held by it for the payment of the principal of, any
          premium or interest on or any Additional Amounts with respect to
          Securities of such series in trust for the benefit of the Persons
          entitled thereto until such sums shall be paid to such Persons or
          otherwise disposed of as provided in or pursuant to this Indenture;

     (2)  give the Trustee notice of any default by the Company (or any other
          obligor upon the Securities of such series) in the making of any
          payment of principal, any premium or interest on or any Additional
          Amounts with respect to the Securities of such series; and

     (3)  at any time during the continuance of any such default, upon the
          written request of the Trustee, forthwith pay to the Trustee all sums
          so held in trust by such Paying Agent.

     The Company may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, pay, or by Company
Order direct any Paying Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying Agent, such sums to be held by the Trustee upon the
same terms as those upon which such sums were held by the Company or such Paying
Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying
Agent shall be released from all further liability with respect to such sums.

     Except as otherwise provided herein or pursuant hereto, any money deposited
with the Trustee or any Paying Agent, or then held by the Company, in trust for
the payment of the principal of, any premium or interest on or any Additional
Amounts with respect to any Security of any series or any Coupon appertaining
thereto and remaining unclaimed for two years after such principal or any such
premium or interest or any such Additional Amounts shall have become

                                       79
<PAGE>

due and payable shall be paid to the Company on Company Request, or (if then
held by the Company) shall be discharged from such trust; and the Holder of such
Security or any Coupon appertaining thereto shall thereafter, as an unsecured
general creditor, look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Company as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required
to make any such repayment, may at the expense of the Company cause to be
published once, in an Authorized Newspaper in each Place of Payment for such
series or to be mailed to Holders of Registered Securities of such series, or
both, notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication
or mailing nor shall it be later than two years after such principal and any
premium or interest or Additional Amounts shall have become due and payable, any
unclaimed balance of such money then remaining will be repaid to the Company.

     Section 1004.  Additional Amounts.

     If any Securities of a series provide for the payment of Additional
Amounts, the Company agrees to pay to the Holder of any such Security or any
Coupon appertaining thereto Additional Amounts as provided in or pursuant to
this Indenture or such Securities.  Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or
interest on, or in respect of, any Security of any series or any Coupon or the
net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established hereby or pursuant
hereto to the extent that, in such context, Additional Amounts are, were or
would be payable in respect thereof pursuant to such terms, and express mention
of the payment of Additional Amounts (if applicable) in any provision hereof
shall not be construed as excluding Additional Amounts in those provisions
hereof where such express mention is not made.

     Except as otherwise provided in or pursuant to this Indenture or the
Securities of any series, if the Securities of a series provide for the payment
of Additional Amounts, at least 10 days prior to the first Interest Payment Date
with respect to such series of Securities (or if the Securities of such series
shall not bear interest prior to Maturity, the first day on which a payment of
principal is made), and at least 10 days prior to each date of payment of
principal or interest if there has been any change with respect to the matters
set forth in the below-mentioned Officers' Certificate, the Company shall
furnish to the Trustee and the principal Paying Agent or Paying Agents, if other
than the Trustee, an Officers' Certificate instructing the Trustee and such
Paying Agent or Paying Agents whether such payment of principal of and premium,
if any, or interest, if any, on the Securities of such series shall be made to
Holders of Securities of such series or the Coupons appertaining thereto who are
United States Aliens without withholding for or on account of any tax,
assessment or other governmental charge described in the Securities of such
series.  If any such withholding shall be required, then such Officers'
Certificate shall specify by country the amount, if any, required to be withheld
on such payments to such Holders of Securities or Coupons, and the Company
agrees to pay to the Trustee or such Paying Agent the Additional Amounts
required by the terms of such Securities.  The Company covenants to indemnify
the Trustee and any Paying Agent for, and to hold them harmless against, any
loss, liability or expense

                                       80
<PAGE>

reasonably incurred without negligence or bad faith on their part arising out of
or in connection with actions taken or omitted by any of them in reliance on any
Officers' Certificate furnished pursuant to this Section.

     Section 1005.  Corporate Existence.

     Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence and the rights (charter and statutory) and franchises of the Company;
provided, however, that the Company shall not be required to preserve any such
right or franchise if the Board of Directors shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
the Company, and that the loss thereof is not disadvantageous in any material
respect to the Holders.

     Section 1006.  Company Statement as to Compliance.

     The Company will deliver to the Trustee, within 120 days after the end of
each fiscal year, an Officers' Certificate (which need not comply with Section
102), stating as to each signer, that

     (1)  a review of the activities of the Company during such year and of
          performance under this Indenture has been made under his or her
          supervision; and

     (2)  to the best of his or her knowledge, based on such review, (a) the
          Company has fulfilled all its obligations under and complied with all
          covenants and conditions contained in this Indenture throughout such
          year, or, if there has been a default in the fulfillment of any such
          covenant, condition or obligation, specifying each such default known
          to him or her and the nature and status thereof, and (b) no event has
          occurred and is continuing which is, or after notice or lapse of time
          or both would become, an Event of Default under Section 501, or, if
          such an event has occurred and is continuing, specifying each such
          event known to him or her and the nature and status thereof.

     At least one of the Person's signing such Officers' Certificate shall be
the Company's principal executive officer, principal financial officer or
principal accounting officer.

     Section 1007.  Calculation of Original Issue Discount.

     The Company shall file with the Trustee promptly after the end of each
calendar year a written notice specifying the amount of original issue discount
(including daily rates and accrual periods) accrued on Outstanding Securities,
if any, as of the end of such year.

REDEMPTION OF SECURITIES

                                       81
<PAGE>

     Section 1101.  Applicability of Article.

     Redemption of Securities of any series at the option of the Company as
permitted or required by the terms of such Securities shall be made in
accordance with the terms of such Securities and (except as otherwise provided
herein or pursuant hereto) this Article.

     Section 1102.  Election to Redeem; Notice to Trustee.

     The election of the Company to redeem any Securities shall be evidenced by
or pursuant to a Company Resolution.  In case of any redemption at the election
of the Company of less than all of the Securities of any series, the Company
shall, at least 60 days prior to the Redemption Date fixed by the Company
(unless a shorter notice shall be satisfactory to the Trustee), notify the
Trustee of such Redemption Date and of the principal amount of Securities of
such series to be redeemed and, in the event that the Company shall determine
that the Securities of any series to be redeemed shall be selected from
Securities of such series having the same issue date, interest rate or interest
rate formula, Stated Maturity and other terms (the "Equivalent Terms"), the
Company shall notify the Trustee of such Equivalent Terms.  In the case of any
redemption of Securities (a) prior to the expiration of any restriction on such
redemption provided in the terms of such Securities or elsewhere in this
Indenture or (b) pursuant to an election of the Company which is subject to a
condition specified in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers' Certificate
evidencing compliance with such restriction or condition.

     Section 1103.  Selection by Trustee of Securities to be Redeemed.

     If less than all of the Securities of any series are to be redeemed (unless
all of the Securities of any series with Equivalent Terms are to be redeemed) or
if less than all of the Securities of any series with Equivalent Terms are to be
redeemed, the particular Securities to be redeemed shall be selected not more
than 60 days prior to the Redemption Date by the Trustee from the Outstanding
Securities of such series or from the Outstanding Securities of such series with
Equivalent Terms, as the case may be, not previously called for redemption, by
such method as the Trustee shall deem fair and appropriate and which may provide
for the selection for redemption of portions of the principal amount of
Registered Securities of such series; provided, however, that no such partial
redemption shall reduce the portion of the principal amount of a Registered
Security of such series not redeemed to less than the minimum denomination for a
Security of such series established herein or pursuant hereto.

     The Trustee shall promptly notify the Company and the Security Registrar
(if other than itself) in writing of the Securities selected for redemption and,
in the case of any Securities selected for partial redemption, the principal
amount thereof to be redeemed.

     For all purposes of this Indenture, unless the context otherwise requires,
all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.

                                       82
<PAGE>

     Unless otherwise specified in or pursuant to this Indenture or the
Securities of any series, if any Security selected for partial redemption is
converted or exchanged for Capital Stock or other securities in part before
termination of the conversion or exchange right with respect to the portion of
the Security so selected, the converted or exchanged portion of such Security
shall be deemed (so far as may be) to be the portion selected for redemption.
Securities which have been converted or exchanged during a selection of
Securities to be redeemed shall be treated by the Trustee as Outstanding for the
purpose of such selection.

     Section 1104.  Notice of Redemption.

     Notice of redemption shall be given in the manner provided in Section 106,
not less than 20 nor more than 60 days prior to the Redemption Date, unless a
shorter period is specified in the Securities to be redeemed, to the Holders of
Securities to be redeemed.  Failure to give notice by mailing in the manner
herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such
Holder, shall not affect the validity of the proceedings for the redemption of
any other Securities or portion thereof.  Any notice that is mailed to the
Holder of any Registered Securities in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not such Holder
receives the notice.

     All notices of redemption shall state:

     (1)  the Redemption Date,

     (2)  the Redemption Price, or if not then ascertainable, the manner of
          calculation thereof,

     (3)  if less than all Outstanding Securities of any series are to be
          redeemed (unless all of the Securities of any series with Equivalent
          Terms are to be redeemed), the identification (and, in the case of
          partial redemption, the principal amount) of the particular Security
          or Securities to be redeemed,

     (4)  in case any Security is to be redeemed in part only, the notice which
          relates to such Security shall state that on and after the Redemption
          Date, upon surrender of such Security, the Holder of such Security
          will receive, without charge, a new Security or Securities of
          authorized denominations for the principal amount thereof remaining
          unredeemed,

     (5)  that, on the Redemption Date, the Redemption Price shall become due
          and payable upon each such Security or portion thereof to be redeemed,
          and, if applicable, that interest thereon shall cease to accrue on and
          after said date,

     (6)  the place or places where such Securities, together (in the case of
          Bearer Securities) with all Coupons appertaining thereto, if any,
          maturing after the Redemption Date,

                                       83
<PAGE>

          are to be surrendered for payment of the Redemption Price and any
          accrued interest and Additional Amounts pertaining thereto,

     (7)  that the redemption is for a sinking fund, if such is the case,

     (8)  that, unless otherwise specified in such notice, Bearer Securities of
          any series, if any, surrendered for redemption must be accompanied by
          all Coupons maturing subsequent to the date fixed for redemption or
          the amount of any such missing Coupon or Coupons will be deducted from
          the Redemption Price, unless security or indemnity satisfactory to the
          Company, the Trustee and any Paying Agent is furnished,

     (9)  if Bearer Securities of any series are to be redeemed and any
          Registered Securities of such series are not to be redeemed, and if
          such Bearer Securities may be exchanged for Registered Securities not
          subject to redemption on the Redemption Date pursuant to Section 305
          or otherwise, the last date, as determined by the Company, on which
          such exchanges may be made,

     (10) in the case of Securities of any series that are convertible or
          exchangeable into Capital Stock or other securities, the conversion or
          exchange price or rate, the date or dates on which the right to
          convert or exchange the principal of the Securities of such series to
          be redeemed will commence or terminate and the place or places where
          such Securities may be surrendered for conversion or exchange, and

     (11) the CUSIP number or the Euroclear or the Cedel reference numbers of
          such Securities, if any (or any other numbers used by a U.S.
          Depositary or Depositary to identify such Securities).

     A notice of redemption published as contemplated by Section 106 need not
identify particular Registered Securities to be redeemed.

     Unless otherwise specified with respect to any Securities in accordance
with Section 301, with respect to any redemption of Securities at the election
of the Company, unless, upon the giving of notice of such redemption, defeasance
shall have been effected with respect to such Securities pursuant to Section
402, such notice may state that such redemption shall be conditional upon the
receipt by the Trustee or the Paying Agent(s) for such Securities, on or prior
to the date fixed for such redemption, of money sufficient to pay the principal
of and any premium and interest on such Securities and that if such money shall
not have been so received such notice shall be of no force or effect and the
Company shall not be required to redeem such Securities. In the event that such
notice of redemption contains such a condition and such money is not so
received, the redemption shall not be made and within a reasonable time
thereafter notice shall be given, in the manner in which the notice of
redemption was given, that such money was not so received and such redemption
was not required to be made, and the Trustee or Paying Agent(s) for the
Securities otherwise to have been redeemed shall promptly return to the Holders
thereof any of such Securities which had been surrendered for payment upon such
redemption.

     Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, on Company Request, by the Trustee in
the name and at the expense of the Company.

     The Company shall give the Trustee notice of the amount of any Redemption
Price that is subject to calculation, promptly after the calculation thereof.

     Section 1105.  Deposit of Redemption Price.

     On or prior to any Redemption Date, the Company shall deposit, with respect
to the Securities of any series called for redemption pursuant to Section 1104,
with the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 1003) an amount
of money in the applicable Currency sufficient to pay the Redemption Price of,
and (except if the Redemption Date shall be an Interest Payment Date, unless
otherwise specified pursuant to Section 301 for or in the Securities of such
series) any accrued interest on and Additional Amounts with respect thereto, all
such Securities or portions thereof which are to be redeemed on that date.

     Section 1106.  Securities Payable on Redemption Date.

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, subject to the fourth paragraph of Section
1104, and from and after such date (unless the Company shall default in the
payment of the Redemption Price and accrued interest) such Securities shall
cease to bear interest and the Coupons for such interest appertaining to any
Bearer Securities so to be redeemed, except to the extent provided below, shall
be void.  Upon surrender of any such Security for redemption in accordance with
said notice, together with all Coupons, if any, appertaining thereto maturing
after the Redemption Date, such Security shall be paid by the Company at the
Redemption Price, together with any accrued interest and Additional Amounts to
the Redemption Date; provided, however, that, except as otherwise provided in or
pursuant to this Indenture or the Bearer Securities of such series, installments
of interest on Bearer Securities whose Stated Maturity is on or prior to the
Redemption Date shall be payable only upon presentation and surrender of Coupons
for such interest (at an Office or Agency located outside the United States
except as otherwise provided in Section 1002), and provided, further, that,
except as otherwise specified in or pursuant to this Indenture or the Registered
Securities of such series, installments of interest on Registered Securities
whose Stated Maturity is on or prior to the Redemption Date shall be payable to
the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business on the Regular Record Dates therefor
according to their terms and the provisions of Section 307.

     If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant Coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing Coupons, or the surrender of such missing Coupon or
Coupons may be waived by the Company

                                       85
<PAGE>

and the Trustee if there be furnished to them such security or indemnity as they
may require to save each of them and any Paying Agent harmless. If thereafter
the Holder of such Security shall surrender to the Trustee or any Paying Agent
any such missing Coupon in respect of which a deduction shall have been made
from the Redemption Price, such Holder shall be entitled to receive the amount
so deducted; provided, however, that any interest or Additional Amounts
represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an Office or Agency for such Security located outside of the
United States except as otherwise provided in Section 1002.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal and any premium, until paid, shall bear
interest from the Redemption Date at the rate prescribed therefor in the
Security.

     Section 1107.  Securities Redeemed in Part.

     Any Registered Security which is to be redeemed only in part shall be
surrendered at any Office or Agency for such Security (with, if the Company or
the Trustee so requires, due endorsement by, or a written instrument of transfer
in form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or his attorney duly authorized in writing) and the Company shall
execute and the Trustee shall authenticate and deliver to the Holder of such
Security without service charge, a new Registered Security or Securities of the
same series, containing identical terms and provisions, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal of the Security so
surrendered.  If a Security in global form is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to the U.S. Depositary
or other Depositary for such Security in global form as shall be specified in
the Company Order with respect thereto to the Trustee, without service charge, a
new Security in global form in a denomination equal to and in exchange for the
unredeemed portion of the principal of the Security in global form so
surrendered.

SINKING FUNDS

     Section 1201.  Applicability of Article.

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series, except as otherwise permitted or
required in or pursuant to this Indenture or any Security of such series issued
pursuant to this Indenture.

     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 such series is herein referred to as an "optional sinking
fund payment".  If provided for by the terms of Securities of

                                       86
<PAGE>

any series, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 1202. 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 and this Indenture.

     Section 1202.  Satisfaction of Sinking Fund Payments with Securities.

     The Company may, in satisfaction of all or any part of any sinking fund
payment with respect to the Securities of any series to be made pursuant to the
terms of such Securities (1) deliver Outstanding Securities of such series
(other than any of such Securities previously called for redemption or any of
such Securities in respect of which cash shall have been released to the
Company), together in the case of any Bearer Securities of such series with all
unmatured Coupons appertaining thereto, and (2) apply as a credit Securities of
such series which have been redeemed either at the election of the Company
pursuant to the terms of such series of Securities or through the application of
permitted optional sinking fund payments pursuant to the terms of such
Securities, 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.  If as a result of the delivery or credit of Securities
of any series in lieu of cash payments pursuant to this Section 1202, the
principal amount of Securities of such series to be redeemed in order to exhaust
the aforesaid cash payment shall be less than $100,000, the Trustee need not
call Securities of such series for redemption, except upon Company Request, and
such cash payment shall be held by the Trustee or a Paying Agent and applied to
the next succeeding sinking fund payment, provided, however, that the Trustee or
such Paying Agent shall at the request of the Company from time to time pay over
and deliver to the Company any cash payment so being held by the Trustee or such
Paying Agent upon delivery by the Company to the Trustee of Securities of that
series purchased by the Company having an unpaid principal amount equal to the
cash payment requested to be released to the Company.

     Section 1203.  Redemption of Securities for Sinking Fund.

     Not less than 75 days prior to each sinking fund payment date for any
series of Securities, the Company shall deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing mandatory sinking fund
payment for that series pursuant to the terms of that series, the portion
thereof, if any, which is to be satisfied by payment of cash and the portion
thereof, if any, which is to be satisfied by delivering and crediting of
Securities of that series pursuant to Section 1202, the basis for such credit,
that such Securities have not been previously so credited and the optional
amount, if any, to be added in cash to the next ensuing mandatory sinking fund
payment, and will also deliver to the Trustee any Securities to be so credited
and not theretofore delivered.  If such Officers' Certificate shall specify an
optional amount to be added in cash to the next ensuing mandatory sinking fund
payment, the Company shall thereupon be obligated to pay the amount therein
specified.  Not less than 45 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 1103 and cause notice of the
redemption thereof to be given in the name of and at the expense of the Company
in the manner provided in Section 1104. Such notice having been duly given, the
redemption of such Securities shall be made upon the terms and in the manner
stated in Sections 1106 and 1107.

     Section 1301. Applicability of Article.

     Whenever this Indenture provides for any distribution to Holders of
Securities of any series in which not all of such Securities are denominated in
the same Currency, in the absence of any provision to the contrary in or
pursuant to this Indenture or the Securities of such series, any amount in
respect of any Security denominated in a Currency other than Dollars shall be
treated for any such distribution as that amount of Dollars that could be
obtained for such amount on such reasonable basis of exchange and as of the
record date with respect to Registered Securities of such series (if any) for
such distribution (or, if there shall be no applicable record date, such other
date reasonably proximate to the date of such distribution) as the Company may
specify in a written notice to the Trustee or, in the absence of such written
notice, as the Trustee may determine.

          series in the amount above specified, as the case may be, may
          determine the time and the place in the Borough of Manhattan, The City
          of New York, or, if Securities of such series are to be issued as

     Except as limited by the proviso to Section 902, any resolution presented
to a meeting or adjourned meeting duly reconvened at which a quorum is present
as aforesaid may be adopted only by the affirmative vote of the Holders of a

amount of the Outstanding Securities of a series may be adopted at a meeting or
an adjourned meeting duly reconvened and at which a quorum is present as

     Section 1405.  Determination of Voting Rights; Conduct and Adjournment of
     Meetings.

     (1)  Notwithstanding any other provisions of this Indenture, the Trustee
          may make such reasonable regulations as it may deem advisable for any
          meeting of Holders of Securities of such series in regard to proof of
          the holding of Securities of such series and of the appointment of
          proxies and in regard to the appointment and duties of inspectors of

          other evidence of the right to vote, and such other matters concerning
          the conduct of the meeting as it shall deem appropriate.  Except as
          otherwise permitted or required by any such regulations, the holding
          of Securities shall be proved in the manner specified in Section 104
          and the appointment of any proxy shall be proved in the manner

          genuine without the proof specified in Section 104 or other proof.

     (2)  The Trustee shall, by an instrument in writing, appoint a temporary
          chairman of the meeting, unless the meeting shall have been called by
          the Company or by Holders of Securities as provided in Section
          1402(2), in which case the Company or the Holders of Securities of the
          series calling the meeting, as the case may be, shall in like manner
          appoint a temporary chairman.  A permanent chairman and a permanent
          secretary of the meeting shall be elected by vote of the Persons

          Securities of such series represented at the meeting.

     (3)  At any meeting, each Holder of a Security of such series or proxy
          shall be entitled to one vote for each $1,000 principal amount of
          Securities of such series held or represented by him; provided,
          however, that no vote shall be cast or counted at any meeting in
          respect of any Security challenged as not Outstanding and ruled by the
          chairman of the meeting to be not Outstanding.  The chairman of the
          meeting shall have no right to vote, except as a Holder of a Security
          of such series or proxy.

     (4)  Any meeting of Holders of Securities of any series duly called
          pursuant to Section 1402 at which a quorum is present may be adjourned
          from time to time by Persons entitled to vote a majority in principal
          amount of the Outstanding Securities of such series represented at the
          meeting; and the meeting may be held as so adjourned without further
          notice.

     Section 1406. Counting Votes and Recording Action of Meetings.

     The vote upon any resolution submitted to any meeting of Holders of
Securities of any series shall be by written ballots on which shall be
subscribed the signatures of the Holders of Securities of such series or of
their representatives by proxy and the principal amounts and serial numbers of
the Outstanding Securities of such series held or represented by them.  The
permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who
shall make and file with the secretary of the meeting their verified written
reports in triplicate of all votes cast at the meeting. A record, at least in
triplicate, of the proceedings of each meeting of Holders of Securities of any
series shall be prepared by the secretary of the meeting and there shall be
attached to said record the original reports of the inspectors of votes on any
vote by ballot taken thereat and affidavits by one or more persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1402 and, if
applicable, Section 1404. Each copy shall be signed and verified by the
affidavits of the permanent chairman and secretary of the meeting and one such
copy shall be delivered to the Company, and another to the Trustee to be
preserved by the Trustee, the latter to have attached thereto the ballots voted
at the meeting. Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

                          SUBORDINATION OF SECURITIES
                          ---------------------------

     Section 1501.  Agreement to Subordinate.

     The Company, for itself, its successors and assigns, covenants and agrees,
and each Holder of Securities by his acceptance thereof, likewise covenants and
agrees, that the payment of the principal of (and premium, if any) and interest,
if any, on, and Additional Amounts, if any, in respect of each and all of the
Securities is hereby expressly subordinated, to the extent and in the manner
hereinafter set forth, in right of payment to the prior payment in full of all
Senior Indebtedness.

     Section 1502.  Distribution on Dissolution, Liquidation and Reorganization;
     Subrogation of Securities.

     Upon any distribution of assets of the Company upon any dissolution,
winding up, liquidation or reorganization of the Company, whether in bankruptcy,
insolvency, reorganization or receivership proceedings or upon an assignment for
the benefit of creditors or any other marshalling of the assets and liabilities
of the Company or otherwise (subject to the power of a court of competent
jurisdiction to make other equitable provision reflecting the rights conferred
in this Indenture upon the Senior Indebtedness and the holders thereof with
respect to the Securities and the holders thereof by a lawful plan of
reorganization under applicable bankruptcy law):

          (a) the holders of all Senior Indebtedness shall be entitled to
receive payment in full of the principal thereof (and premium, if any) and
interest due thereon before the Holders of the Securities are entitled to
receive any payment upon the principal (or premium, if any) or interest, if any,
on, or Additional Amounts, if any, in respect of the indebtedness evidenced by
the Securities; and

          (b) any payment or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, to which the Holders of
the Securities or the Trustee would be entitled except for the provisions of
this Article Fifteen shall be paid by the liquidating trustee or agent or other
person making such payment or distribution, whether a trustee in bankruptcy, a
receiver or liquidating trustee or otherwise, directly to the holders of Senior
Indebtedness or their representative or representatives or to the trustee or
trustees under any indenture under which any instruments evidencing any of such
Senior Indebtedness may have been issued, ratably according to the aggregate
amounts remaining unpaid on account of the principal of (and premium, if any)
and interest on the Senior Indebtedness held or represented by each, to the
extent necessary to make payment in full of all Senior Indebtedness remaining
unpaid, after giving effect to any concurrent payment or distribution to the
holders of such Senior Indebtedness; and

          (c) in the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, shall be received by the Trustee or the Holders of the
Securities before all Senior Indebtedness is paid in full, such payment or
distribution shall be paid over, upon written notice to the Trustee, to the
holders of such Senior Indebtedness or their representative or representatives
or to the trustee or trustees under any indenture under which any instrument
evidencing any of such Senior Indebtedness may have been issued, ratably as
aforesaid, for application to payment of all Senior Indebtedness remaining
unpaid until all such Senior Indebtedness shall have been paid in full, after
giving effect to any concurrent payment or distribution to the holders of such
Senior Indebtedness.

     Subject to the payment in full of all Senior Indebtedness, the Holders of
the Securities shall be subrogated to the rights of the holders of Senior
Indebtedness to receive payments or distributions of cash, property or
securities of the Company applicable to Senior Indebtedness until the principal
of (and premium, if any) and interest, if any, on, or Additional Amounts, if
any, in respect of the Securities shall be paid in full and no such payments or

                                      92

<PAGE>

distributions to the Holders of the Securities of cash, property or securities
otherwise distributable to the holders of Senior Indebtedness shall, as between
the Company, its creditors other than the holders of Senior Indebtedness, and
the Holders of the Securities be deemed to be a payment by the Company to or on
account of the Securities.  It is understood that the provisions of this Article
Fifteen are and are intended solely for the purpose of defining the relative
rights of the Holders of the Securities, on the one hand, and the holders of the
Senior Indebtedness, on the other hand.  Nothing contained in this Article
Fifteen or elsewhere in this Indenture or in the Securities is intended to or
shall impair, as between the Company, its creditors other than the holders of
Senior Indebtedness, and the Holders of the Securities, the obligation of the
Company, which is unconditional and absolute, to pay to the Holders of the
Securities the principal of (and premium, if any) and interest, if any, on, or
Additional Amounts, if any, in respect of the Securities as and when the same
shall become due and payable in accordance with their terms, or to affect the
relative rights of the Holders of the Securities and creditors of the Company
other than the holders of Senior Indebtedness, nor shall anything herein or in
the Securities prevent the Trustee or the Holder of any Security from exercising
all remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article Fifteen of the
holders of Senior Indebtedness in respect of cash, property or securities of the
Company received upon the exercise of any such remedy.  Upon any payment or
distribution of assets of the Company referred to in this Article Fifteen, the
Trustee, subject to the provisions of Section 601, shall be entitled to rely
upon a certificate of the liquidating trustee or agent or other person making
any distribution to the Trustee for the purpose of ascertaining the Persons
entitled to participate in such distribution, the holders of Senior Indebtedness
and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article Fifteen.

     The Trustee, however, shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness.  The Trustee shall not be liable to any such
holder if it shall pay over or distribute to or on behalf of Holders of
Securities or the Company moneys or assets to which any holder of Senior
Indebtedness shall be entitled by virtue of this Article Fifteen.

     If the Trustee or any Holder of Securities does not file a proper claim or
proof of debt in the form required in any proceeding referred to above prior to
30 days before the expiration of the time to file such claim in such proceeding,
then the holder of any Senior Indebtedness is hereby authorized, and has the
right, to file an appropriate claim or claims for or on behalf of such Holder of
Securities.

     Section 1503.  No Payment on Securities in Event of Default on Senior
     Indebtedness.

     No payment by the Company on account of principal (or premium, if any),
sinking funds or interest, if any, on, or Additional Amounts, if any, in respect
of the Securities shall be made unless full payment of amounts then due for the
principal of (and premium, if any), sinking funds and interest, if any, on
Senior Indebtedness has been made or duly provided for in money or money's
worth.

     Section 1504.  Payments on Securities Permitted.

     Nothing contained in this Indenture or in any of the Securities shall (a)
affect the obligation of the Company to make, or prevent the Company from
making, at any time except as provided in Sections 1502 and 1503, payments of
principal of (or premium, if any) or interest, if any, on, or Additional Amounts
or sinking fund payments, if any, with respect to the Securities or (b) prevent
the application by the Trustee of any moneys deposited with it hereunder to the
payment of or on account of the principal of (or premium, if any) or interest,
if any, on, or Additional Amounts, if any, in respect of the Securities, unless
the Trustee shall have received at its Corporate Trust Office written notice of
any event prohibiting the making of such payment more than two Business Days
prior to the date fixed for such payment.

     Section 1505.  Authorization of Holders to Trustee to Effect Subordination.

     Each Holder of Securities by his acceptance thereof authorizes and directs
the Trustee on his behalf to take such action as may be necessary or appropriate
to effectuate the subordination as provided in this Article Fifteen and appoints

                                      93

the Trustee his attorney-in-fact for any and all such purposes.

     Section 1506.  Notices to Trustee.

     The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities pursuant to this Article Fifteen.  Failure
to give such notice shall not affect the subordination of the Securities to
Senior Indebtedness.  Notwithstanding the provisions of this Article Fifteen or
any other provisions of this Indenture, neither the Trustee nor any Paying Agent
(other than the Company) shall be charged with knowledge of the existence of any
Senior Indebtedness or of any event which would prohibit the making of any
payment of moneys to or by the Trustee or such Paying Agent, unless and until
the Trustee or such Paying Agent shall have received (in the case of the
Trustee, at its Corporate Trust Office) written notice thereof from the Company
or from the holder of any Senior Indebtedness or from the trustee for any such
holder, together with proof satisfactory to the Trustee of such holding of
Senior Indebtedness or of the authority of such trustee; provided, however, that
if at least two Business Days prior to the date upon which by the terms hereof
any such moneys may become payable for any purpose (including, without
limitation, the payment of either the principal of (or premium, if any) or
interest, if any, on any Security) the Trustee shall not have received with
respect to such moneys the notice provided for in this Section 1506, then,
anything herein contained to the contrary notwithstanding, the Trustee shall
have full power and authority to receive such moneys and to apply the same to
the purpose for which they were received, and shall not be affected by any
notice to the contrary, which may be received by it within two Business Days
prior to such date.  The Trustee shall be entitled to rely on the delivery to it
of a written notice by a Person representing himself to be a holder of Senior
Indebtedness (or a trustee on behalf of such holder) to establish that such a
notice has been given by a holder of Senior Indebtedness or a trustee on behalf
of any such holder.  In the event that the Trustee determines in good faith that
further evidence is required with respect to the right of any Person as a holder
of Senior Indebtedness (or a trustee on behalf of such holder) to participate in
any payment or distribution pursuant to this Article Fifteen, the Trustee may
request such Person to furnish evidence to the reasonable satisfaction of the
Trustee as to the amount of Senior Indebtedness held by such Person (or the
amount of Senior Indebtedness as to which such Person is trustee), the extent to
which such Person is entitled to participate in such payment or distribution and
any other facts pertinent to the rights of such Person under this Article
Fifteen and, if such evidence is not furnished, the Trustee may defer any
payment to such Person pending judicial determination as to the right of such
Person to receive such payment.

     Section 1507.  Trustee as Holder of Senior Indebtedness.

     The Trustee in its individual capacity shall be entitled to all the rights
set forth in this Article Fifteen in respect of any Senior Indebtedness at any
time held by it to the same extent as any other holder of Senior Indebtedness
and nothing in this Indenture shall be construed to deprive the Trustee of any
of its rights as such holder.

     Nothing in this Article Fifteen shall apply to claims of, or payments to,
the Trustee under or pursuant to Section 606.

     Section 1508.  Modifications of Terms of Senior Indebtedness.

     Any renewal or extension of the time of payment of any Senior Indebtedness
or the exercise by the holders of Senior Indebtedness of any of their rights
under any instrument creating or evidencing Senior Indebtedness, including,
without limitation, the waiver of default thereunder, may be made or done all
without notice to or assent from the Holders of the Securities or the Trustee.

     No compromise, alteration, amendment, modification, extension, renewal or
other change of, or waiver, consent or other action in respect of, any liability
or obligation under or in respect of, or of any of the terms, covenants or
conditions of any indenture or other instrument under which any Senior
Indebtedness is outstanding or of such Senior Indebtedness, whether or not such
release is in accordance with the provisions of any applicable document, shall
in any way alter or affect any of the provisions of this Article Fifteen or of
the Securities relating to the subordination thereof.

     Section 1509.  Reliance on Judicial Order or Certificate of Liquidating
     Agent.

                                      94

<PAGE>

     Upon any payment or distribution of assets of the Company referred to in
this Article Fifteen, the Trustee and the Holders of the Securities shall be
entitled to rely upon any order or decree entered by any court of competent
jurisdiction in which such insolvency, bankruptcy, receivership, liquidation,
reorganization, dissolution, winding up or similar case or proceeding is
pending, or a certificate of the trustee in bankruptcy, liquidating trustee,
custodian, receiver, assignee for the benefit of creditors, agent or other
person making such payment or distribution, delivered to the Trustee or to the
Holders of Securities, for the purpose of ascertaining the persons entitled to
participate in such payment or distribution, the holders of Senior Indebtedness
and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article Fifteen.

ARTICLE SIXTEEN

or because of the creation of any indebtedness represented thereby, shall be had
against any incorporator, stockholder, officer or director, as such, past,
present or future, of the Company or of any successor corporation, either
directly or through the Company or any successor corporation, whether by virtue
of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise; it being expressly understood that all such
liability is hereby expressly waived and released as a condition of, and as a
consideration for, the execution of this Indenture and the issue of the
