          (b) The  Company  will  advise  the  Representatives  promptly  of any
     proposal  to  amend  or  supplement  the  Registration   Statement  or  the
     Prospectus and will afford the Representatives a reasonable  opportunity to
     comment on any such proposed amendment or supplement;  and the Company will
     also  advise  the  Representatives  promptly  of the  filing  of  any  such


                                       9



     amendment or supplement  and of the  institution  by the  Commission of any
     stop order  proceedings in respect of the Registration  Statement or of any
     part  thereof and will use its best  efforts to prevent the issuance of any
     such stop order and to obtain as soon as possible its lifting, if issued;

          (c) If,  at any  time  when a  prospectus  relating  to the  Notes  is
     required to be delivered  under the Securities Act in connection with sales
     by any Underwriter or any dealer, any event occurs as a result of which the
     Prospectus  as  then  amended  or  supplemented  would  include  an  untrue
     statement of a material fact or omit to state any material  fact  necessary
     to make the statements  therein,  in the light of the  circumstances  under
     which they were made, not misleading,  or if it is necessary at any time to
     amend the  Prospectus  to  comply  with the  Securities  Act,  the  Company
     promptly  will notify the  Representatives  of such event and will promptly
     prepare and file with the Commission,  at its own expense,  an amendment or
     supplement  which will correct  such  statement or omission or an amendment
     which will effect such compliance. Neither the Representatives' consent to,
     nor any  Underwriter's  delivery of, any such amendment or supplement shall
     constitute a waiver of any of the conditions set forth in Section 6 hereof;

          (d) As soon as  practicable,  but not later  than 16 months  after the
     date of this  Agreement,  the Company will make generally  available to its
     securityholders  an  earnings  statement  covering  a period of at least 12
     months  beginning  after  the  later  of  (i)  the  effective  date  of the
     registration  statement  relating to the Notes,  (ii) the effective date of
     the most recent post-effective  amendment to the Registration  Statement to
     become  effective prior to the date of this Agreement and (iii) the date of
     the  Company's  most  recent  Annual  Report  on Form 10-K  filed  with the
     Commission  prior to the date of this  Agreement,  which will  satisfy  the
     provisions of Section 11(a) of the Securities Act;

          (e) The Company will furnish to each  Underwriter  and counsel for the
     Underwriters,  at the expense of the  Company,  copies of the  Registration
     Statement in the form it became effective (of which will be signed and will
     include  all  exhibits)  and of all  amendments  thereto  and, so long as a
     prospectus  relating to the Notes is required to be delivered under the Act
     in connection with sales by any  Underwriter or any dealer,  the Prospectus
     and all amendments and supplements to such documents,  in each case in such
     quantities  as  such  Underwriter  requests.  The  Prospectus  shall  be so
     furnished  on or prior to 3:00 P.M.,  New York time,  on the  Business  Day
     following the execution and delivery of this Agreement. All other documents
     shall be so furnished as soon as available;

          (f) The Company  will arrange for the  qualification  of the Notes for
     sale under the laws of such jurisdictions as the Representatives  designate
     and will continue such qualifications in effect so long as required for the
     distribution; provided that the Company shall not be required to qualify as
     a foreign  corporation,  file a general  consent  to  service of process or
     become subject to taxation in any jurisdiction;


                                       10



          (g) During the period  beginning on the date hereof and  continuing to
     and including  the Business Day  following the Closing Date,  not to offer,
     sell,  contract to sell or otherwise  dispose of any debt  securities of or
     guaranteed by the Company which are substantially similar to the Notes;

          (h)  to  file  promptly  all  reports  and  any  definitive  proxy  or
     information  statements  required  to be  filed  by the  Company  with  the
     Commission  pursuant to Section 13(a),  13(c),  14 or 15(d) of the Exchange
     Act for so long as the delivery of a prospectus  is required in  connection
     with the  offering or sale of the Notes,  and during such same  period,  to
     advise you  promptly,  and to confirm such advice in writing,  (i) when any
     amendment  to  the  Registration   Statement  has  been  filed  or  becomes
     effective;  (ii) when any  supplement to the Prospectus or any amendment to
     the Prospectus  has been filed;  (iii) of any request by the Commission for
     any amendment to the Registration  Statement or any amendment or supplement
     to the  Prospectus  or the  receipt  of any  comments  from the  Commission
     relating  to  the  Registration  Statement  or  any  other  request  by the
     Commission  for any  additional  information,  (iv) of the  issuance by the
     Commission of any order  suspending the  effectiveness  of the Registration
     Statement or  preventing  or  suspending  the use of the  Prospectus or the
     initiation or threatening  of any  proceeding for that purpose;  (v) of the
     occurrence  of any event  within such period of time after the Closing Date
     as in the opinion of counsel for the Underwriters  (after consultation with
     the  Company) a  prospectus  relating to the Notes is required by law to be
     delivered  in  connection  with  sales of the Notes by any  Underwriter  or
     dealer  as a result of such  occurrence  or event  the  Prospectus  as then
     amended or  supplemented  would include any untrue  statement of a material
     fact or omit to  state a  material  fact  necessary  in  order  to make the
     statements  therein,  in the light of the  circumstances  existing when the
     Prospectus is delivered to a purchaser, not misleading; (vi) of the receipt
     by the  Company  of any  notice  with  respect  to  any  suspension  of the
     qualification  of the Notes for offer and sale in any  jurisdiction  or the
     initiation or threatening  of any  proceeding for such purpose;  and to use
     its  reasonable  best  efforts to prevent  the  issuance  of any such order
     suspending the effectiveness of the Registration  Statement,  preventing or
     suspending the use of the  Prospectus or suspending any such  qualification
     of the Notes  and,  if any such  order is  issued,  will  obtain as soon as
     possible the withdrawal thereof;

          (i) to use the net  proceeds  received by the Company from the sale of
     the  Notes  pursuant  to this  Agreement  in the  manner  specified  in the
     Prospectus under the caption "Use of Proceeds"; and

          (j) whether or not the transactions contemplated in this Agreement are
     consummated or this Agreement is terminated, to pay or cause to be paid all
     costs  and  expenses   incident  to  the  performance  of  its  obligations
     hereunder,  including without limiting the generality of the foregoing, all
     costs and expenses (i) incident to the  preparation,  issuance,  execution,
     authentication  and  delivery of the Notes,  including  any expenses of the
     Trustee,  (ii) incident to the  preparation,  printing and filing under the
     Securities Act of the Registration  Statement and the Prospectus (including


                                       11



     in each case all  exhibits,  amendments  and  supplements  thereto),  (iii)
     incurred  in  connection  with  the  registration  or   qualification   and
     determination  of eligibility for investment of the Notes under the laws of
     such  jurisdictions as the  Underwriters  may designate  (including fees of
     counsel for the Underwriters and their disbursements),  (iv) related to any
     filing with  National  Association  of  Securities  Dealers,  Inc.,  (v) in
     connection  with the printing  (including  word  processing and duplication
     costs) and delivery  (including mailing and shipping) of the Prospectus and
     any other  materials  furnished to the  Underwriters in connection with the
     issuance  and sale of the Notes,  as herein  provided  and (vi)  payable to
     rating agencies in connection with the rating of the Notes.

     6. Conditions to Obligations of the Underwriters.  The several  obligations

     and all conditions on its part to be performed or satisfied hereunder at or
     prior to the Closing Date;

          (c) the Prospectus shall have been filed with the Commission  pursuant
     to Rule 424 within the applicable time periods  prescribed for such filings
     by the rules  and  regulations  under the  Securities  Act;  no stop  order
     suspending the  effectiveness  of the  Registration  Statement  shall be in
     effect,  and no  proceedings  for such purpose  shall be pending  before or
     threatened by the Commission;  and all requests for additional  information
     on the  part  of the  Commission  shall  have  been  complied  with to your
     satisfaction;

          (d)  subsequent to the  execution  and delivery of this  Agreement and
     prior to the Closing Date,  there shall not have occurred any  downgrading,
     nor  shall any  notice  have been  given of (i) any  downgrading,  (ii) any
     intended or potential  downgrading  or (iii) any review or possible  change
     that  does  not  indicate  an  improvement,  in  the  rating  accorded  any
     securities of or guaranteed  by the Company by any  "nationally  recognized
     statistical rating  organization",  as such term is defined for purposes of
     Rule 436(g)(2) under the Securities Act;

          (e) since the respective dates as of which information is given in the
     Prospectus  (exclusive  of any  amendment or  supplement  thereto after the
     execution and delivery hereof), there shall not have been any change in the
     capital stock or long-term  debt of the Company or any of its  subsidiaries
     or any material adverse change, or any development  involving a prospective
     material  adverse change,  in or affecting the general  affairs,  business,
     prospects,  management, financial position, stockholders' equity or results

     otherwise than as set forth or contemplated in the Prospectus (exclusive of


                                       12



     any  amendment or  supplement),  the effect of which in the judgment of the
     Representatives  makes it  impracticable or inadvisable to proceed with the
     exchange or the  delivery or public  offering of the Notes on the terms and
     in the manner contemplated in the Prospectus (exclusive of any amendment or
     supplement);  and  neither  the  Company  nor any of its  subsidiaries  has
     sustained  since  the  date  of the  latest  audited  financial  statements
     included or  incorporated  by reference in the Prospectus any material loss
     or  interference  with its business  from fire,  explosion,  flood or other
     calamity, whether or not covered by insurance, or from any labor dispute or
     court or governmental action, order or decree,  otherwise than as set forth
     or  contemplated   in  the  Prospectus   (exclusive  of  any  amendment  or
     supplement);

          (f) the  Representatives  shall have received on and as of the Closing
     Date a certificate  of an executive  officer of the Company,  with specific
     knowledge about the Company's financial matters, satisfactory to you to the
     effect  set forth in  subsections  (b)  through  (d) (with  respect  to the
     respective  representations,  warranties,  agreements and conditions of the
     Company)  of this  Section 6 and to the  further  effect that there has not
     occurred  any  material  adverse  change,  or any  development  involving a
     prospective  material adverse change,  in or affecting the general affairs,
     business, prospects,  management,  financial position, stockholders' equity
     or results of  operations  of the Company and its  subsidiaries  taken as a
     whole from that set forth or contemplated  in the Prospectus  (exclusive of
     any amendment or supplement);

          (g) the  Representatives  shall have received on and as of the Closing
     Date the opinion of the General  Counsel or Deputy  General  Counsel of the
     Company,  or such other legal counsel  employed by the Company agreed to in
     writing by the Representatives, to the effect set forth in Exhibit A hereto
     dated as of the  Closing  Date and in form and  substance  satisfactory  to
     them;

          (h) the  Representatives  shall have received on and as of the Closing
     Date the opinion of Simpson Thacher & Bartlett LLP, counsel to the Company,
     to the  effect set forth in  Exhibit  B-1 hereto and the letter  related to
     certain  matters to the effect set forth in Exhibit B-2 hereto,  each dated

          (i) the  Representatives  shall have received on and as of the Closing

     form and substance  reasonably  satisfactory to the Underwriters,  and such
     counsel  shall  have  received  such  papers  and  information  as they may
     reasonably request to enable them to pass upon such matters;


                                       13



          (j) on the date hereof and on the Closing Date,  Deloitte & Touche LLP
     shall have furnished to you letters,  dated such respective  dates, in form

     Representatives in their respective reasonable judgments; and

          (l) on or prior to the Closing Date,  the Company shall have furnished
     to the  Representatives  such  further  certificates  and  documents as the

     7. Indemnification and Contribution.

     (a) The Company will  indemnify  and hold harmless  each  Underwriter,  its
partners,  directors  and officers and each  person,  if any, who controls  such
Underwriter  within the  meaning of Section 15 of the Act,  against  any losses,
claims, damages or liabilities,  joint or several, to which such Underwriter may
become  subject,  under the Act or  otherwise,  insofar as such losses,  claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue  statement or alleged  untrue  statement  of any  material  fact
contained in (i) the Registration  Statement, or any amendment thereto, or arise
out of or are based upon the  omission or alleged  omission  to state  therein a
material fact  required to be stated  therein or necessary to make the statement
therein not misleading,  or (ii) the Prospectus,  or any amendment or supplement
thereto,  or arise out of or are based upon the omission or alleged  omission to
state  therein,  a material fact  required to be stated  therein or necessary to
make the statements  therein, in the light of the circumstances under which they
were made, not misleading,  and will reimburse each Underwriter for any legal or
other  expenses  reasonably  incurred by such  Underwriter  in  connection  with
investigating or defending any such loss, claim, damage,  liability or action as
such  expenses are  incurred;  provided,  however,  that the Company will not be
liable in any such  case to the  extent  that any such  loss,  claim,  damage or
liability  arises out of or is based upon an untrue  statement or alleged untrue
statement  in or  omission or alleged  omission  from any of such  documents  in
reliance  upon and in  conformity  with  written  information  furnished  to the
Company by such  Underwriter  through the  Representatives  specifically for use
therein, it being understood and agreed that the only such information furnished
by any Underwriter  consists of the information  described as such in subsection
(b) below.

     (b) Each  Underwriter,  severally and not jointly,  will indemnify and hold
harmless the Company,  its  directors  and officers and each person,  if any who
controls  the Company  within the meaning of Section 15 of the Act,  against any
losses, claims,  damages or liabilities,  joint or several, to which the Company
may become subject, under the Act or otherwise,  insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based


                                       14



upon any untrue  statement or alleged  untrue  statement  of any  material  fact
contained in (i) the Registration  Statement, or any amendment thereto, or arise
out of or are based upon the  omission or alleged  omission  to state  therein a
material fact  required to be stated  therein or necessary to make the statement
therein not misleading,  or (ii) the Prospectus,  or any amendment or supplement
thereto,  or arise out of or are based upon the omission or the alleged omission
to state therein a material  fact required to be stated  therein or necessary to
make the statements  therein, in the light of the circumstances under which they
were made, not misleading,  in each case to the extent,  but only to the extent,
that such untrue  statement or alleged  untrue  statement or omission or alleged
omission was made in reliance  upon and in conformity  with written  information
furnished  to the  Company  by  such  Underwriter  through  the  Representatives
specifically  for use therein,  and will  reimburse any legal or other  expenses
reasonably incurred by the Company in connection with investigating or defending
any such loss, claim, damage, liability or action as such expenses are incurred,
it being understood and agreed that the only such  information  furnished by any
Underwriter consists of the following information in the Prospectus furnished on
behalf of the  Underwriters:  the information  contained in the third and fourth
sentences  of the fourth  paragraph on the front cover  regarding  offers of the
notes by the  underwriters;  the  information  contained  in the first,  second,
fourth  and  fifth   sentences  of  the  fourth   paragraph  under  the  caption
"Underwriting"  regarding  offers  of the  notes  by the  underwriters;  and the
information  contained  in the sixth,  seventh and eighth  paragraphs  under the
caption  "Underwriting"  regarding  stabilizing   transactions,   over-allotment
transactions, syndicate covering transactions and penalty bids.

     (c) Promptly after receipt by an indemnified  party under this Section 7 of
notice of the  commencement  of any action,  such  indemnified  party will, if a
claim in respect  thereof is to be made  against  the  indemnifying  party under
subsection (a) or (b) above,  notify the indemnifying  party of the commencement
thereof;  but the failure to notify the indemnifying  party shall not relieve it
from any liability that it may have under  subsection (a) or (b) above except to
the  extent  that it has  been  materially  prejudiced  (including  through  the
forfeiture  of  substantive  rights or defenses) by such  failure;  and provided
further that the failure to notify the  indemnifying  party shall not relieve it
from any liability that it may have to an indemnified party otherwise than under
subsection  (a) or (b) above.  In case any such  action is brought  against  any
indemnified  party and it notifies the  indemnifying  party of the  commencement
thereof,  the indemnifying party will be entitled to participate therein and, to
the extent that it may wish, jointly with any other indemnifying party similarly
notified,  to assume the defense  thereof,  with  counsel  satisfactory  to such
indemnified  party (who shall not,  except with the  consent of the  indemnified
party,  be  counsel  to the  indemnifying  party),  and  after  notice  from the
indemnifying  party to such  indemnified  party of its election so to assume the
defense thereof,  the indemnifying  party will not be liable to such indemnified
party under this Section 7 for any legal or other expenses subsequently incurred
by such  indemnified  party in  connection  with the defense  thereof other than


                                       15



reasonable  costs of  investigation.  No indemnifying  party shall,  without the
prior written  consent of the  indemnified  party,  effect any settlement of any
pending or  threatened  action in respect of which any  indemnified  party is or
could have been a party and indemnity  could have been sought  hereunder by such
indemnified  party unless such settlement (i) includes an unconditional  release
of such indemnified  party from all liability on any claims that are the subject
matter  of such  action  and (ii)  does not  include  a  statement  as to, or an
admission  of,  fault,  culpability  or a  failure  to act by or on behalf of an
indemnified party.

     (d) If the indemnification provided for in this Section 7 is unavailable or
insufficient to hold harmless an indemnified  party under  subsection (a) or (b)
above,  then each  indemnifying  party  shall  contribute  to the amount paid or
payable by such indemnified party as a result of the losses,  claims, damages or
liabilities referred to in subsection (a) or (b) above (i) in such proportion as
is appropriate to reflect the relative  benefits  received by the Company on the
one hand and the  Underwriters  on the other from the offering of the Securities
or (ii) if the  allocation  provided  by clause  (i) above is not  permitted  by
applicable  law, in such  proportion as is  appropriate  to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company on the one hand and the Underwriters on the other in connection with
the statements or omissions  which resulted in such losses,  claims,  damages or
liabilities as well as any other relevant equitable considerations. The relative
benefits  received  by the Company on the one hand and the  Underwriters  on the
other shall be deemed to be in the same  proportion as the  aggregate  principal
amount of the Notes  bears to the  difference  between the  aggregate  principal
amount of the Notes and the Surrender Value of the Old Notes. The relative fault
shall be determined  by reference to, among other things,  whether the untrue or
alleged untrue  statement of a material fact or the omission or alleged omission
to state a material fact relates to  information  supplied by the Company or the
Underwriters and the parties' relative intent, knowledge,  access to information
and  opportunity  to correct or prevent such untrue  statement or omission.  The
amount paid by an indemnified party as a result of the losses,  claims,  damages
or liabilities referred to in the first sentence of this subsection (d) shall be
deemed  to  include  any legal or other  expenses  reasonably  incurred  by such
indemnified  party in connection with  investigating  or defending any action or
claim  which  is  the  subject  of  this  subsection  (d).  Notwithstanding  the
provisions  of  this  subsection  (d),  no  Underwriter  shall  be  required  to
contribute  any amount in excess of the amount by which the total price at which
the Notes  underwritten  by it and distributed to the public were offered to the
public  exceeds the amount of any damages which such  Underwriter  has otherwise
been  required to pay by reason of such untrue or alleged  untrue  statement  or
omission or alleged omission.  No person guilty of fraudulent  misrepresentation
(within  the  meaning  of  Section  11(f)  of the  Act)  shall  be  entitled  to
contribution   from  any  person   who  was  not   guilty  of  such   fraudulent
misrepresentation.


                                       16



     (e) The  obligations  of the  Company  under  this  Section  7 shall  be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and  conditions,  to each  person,  if any, who controls any
Underwriter  within  the  meaning  of the  Act;  and  the  obligations  of  each
Underwriter  under this  Section 7 shall be in addition to any  liability  which
such  Underwriter  may otherwise have and shall extend,  upon the same terms and
conditions,  to each director of the Company, to each officer of the Company who
has signed the Registration  Statement and to each person,  if any, who controls
the Company within the meaning of the Act.

     8. Termination.  Notwithstanding anything herein contained,  this Agreement
may be terminated in the absolute discretion of the  Representatives,  by notice
given to the Company,  if after the execution and delivery of this Agreement and
prior to the Closing  Date (i) trading  generally  shall have been  suspended or
materially  limited  on or by,  as the  case may be,  any of the New York  Stock
Exchange or the Chicago Board Options  Exchange,  (ii) trading of any securities
of or guaranteed by the Company shall have been  suspended on any exchange or in
any  over-the-counter  market,  (iii) a general moratorium on commercial banking
activities  in New York shall have been  declared by either  Federal or New York
State authorities,  or (iv) there shall have occurred any outbreak or escalation
of  hostilities  or any change in  financial  markets or any calamity or crisis,
either  within or outside  the  United  States,  that,  in the  judgment  of the
Representatives,  is material and adverse makes it  impracticable or inadvisable
to proceed with the  exchange,  sale or delivery or offering of the Notes on the
Closing Date on the terms and in the manner  contemplated  by this Agreement and
the Prospectus.

     9. Default by One or More of the Underwriters. If, on the Closing Date, any
one or more of the Underwriters  shall fail or refuse to purchase Notes which it
or they  have  agreed  to  purchase  under  this  Agreement,  and the  aggregate
principal  amount of Notes which such  defaulting  Underwriter  or  Underwriters
agreed  but  failed or refused to  purchase  is not more than  one-tenth  of the
aggregate  principal  amount  of the  Notes,  the  other  Underwriters  shall be
obligated  severally in the proportions  that the principal  amount of Notes set
forth  opposite  their  respective  names in  Schedule  II  hereto  bears to the
aggregate  principal  amount of Notes set forth  opposite  the names of all such
non-defaulting Underwriters, or in such other proportions as the Representatives
may  specify,  to  purchase  the Notes  which  such  defaulting  Underwriter  or
Underwriters  agreed but failed or refused to  purchase  on such date;  provided
that in no event shall the principal  amount of Notes that any  Underwriter  has
agreed to purchase pursuant to Section 2 be increased pursuant to this Section 9
by an amount in excess of one-tenth of such  principal  amount of Notes  without
the  written  consent  of  such  Underwriter.  If,  on  the  Closing  Date,  any
Underwriter  or  Underwriters  shall  fail or refuse to  purchase  Notes and the
aggregate principal amount of Notes with respect to which such default occurs is
more than one-tenth of the aggregate  principal amount of Notes to be purchased,
and  arrangements  satisfactory  to you and the Company for the purchase of such
Notes are not made  within 24 hours after such  default,  this  Agreement  shall
terminate without liability on the part of any non-defaulting Underwriter or the
Company.  In any such case  either  you or the  Company  shall have the right to
postpone the Closing Date,  but in no event for longer than seven days, in order


                                       17



that the required  changes,  if any, in the  Registration  Statement  and in the
Prospectus or in any other documents or arrangements may be effected. Any action
taken under this  paragraph  shall not relieve any defaulting  Underwriter  from
liability in respect of any default of such Underwriter under this Agreement.

     10. Survival of Certain  Representations  and  Obligations.  The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the Underwriters set forth in or made pursuant to
this  Agreement  will  remain  in  full  force  and  effect,  regardless  of any
investigation,  or statement as to the results thereof,  made by or on behalf of
any  Underwriter,  the  Company  or any  of  their  respective  representatives,
officers or directors or any controlling  person,  and will survive  delivery of
and  payment for the Notes.  If for any reason the  purchase of the Notes by the
Underwriters is not  consummated,  the Company shall remain  responsible for the
expenses to be paid or reimbursed by it pursuant to Section 5 and the respective
obligations  of the  Company  and the  Underwriters  pursuant to Section 7 shall
remain  in  effect,  and  if  any  Notes  have  been  purchased   hereunder  the
representations  and warranties in Section 1 and all obligations under Section 5
shall also remain in effect. If the purchase of the Notes by the Underwriters is
not  consummated  for any reason other than solely  because of the occurrence of
any event  specified in Section 8, the Company will  reimburse the  Underwriters
for all  out-of-pocket  expenses  (including fees and  disbursements of counsel)
reasonably incurred by them in connection with the offering of the Notes.

     11. Notices.  All communications  hereunder will be in writing and, if sent

will have any right or obligation hereunder.

                      FORM OF OPINION OF GENERAL COUNSEL OR
                      DEPUTY GENERAL COUNSEL OF THE COMPANY
                    TO BE DELIVERED PURSUANT TO SECTION 6(g)

     1. The  Company  has been duly  incorporated  and is validly  existing as a
corporation in good standing under the laws of the State of New York.

     2. The Company has corporate  power and authority to own, lease and operate
its properties and to conduct its business as described in the Prospectus and to
enter into the Agreement and consummate  the  transactions  contemplated  in the
Prospectus.

     3. The  Company is duly  qualified  as a foreign  corporation  to  transact
business  and  is  in  good  standing  in  each   jurisdiction   in  which  such
qualification  is  required,  whether by reason of the  ownership  or leasing of
property or the conduct of  business,  except where the failure to so qualify or
be in good standing would not result in a material adverse effect on the Company
and its subsidiaries, taken as a whole.

     4. Each  Significant  Subsidiary  (as such term is  defined in Rule 1-02 of
Regulation S-X promulgated  under the Securities Act) has been duly incorporated
and is validly existing as a corporation or a limited liability company,  as the
case  may be,  in good  standing  under  the  laws  of the  jurisdiction  of its
incorporation or  organization,  has corporate power and authority to own, lease
and  operate its  properties  and to conduct its  business as  described  in the
Prospectus and is duly qualified as a foreign  corporation or limited  liability
company,  as the case may be, to transact  business  and is in good  standing in
each jurisdiction in which such qualification is required,  whether by reason of
the  ownership or leasing of property or the conduct of  business,  except where
the failure to so qualify or be in good standing  would not result in a material
adverse effect on the Company and its subsidiaries,  taken as a whole; except as
stated  in the  Prospectus,  all of  the  membership  interests  or  issued  and
outstanding shares of capital stock of each Significant Subsidiary has been duly
authorized and with respect to such stock,  are validly  issued,  fully paid and
non-assessable  and,  to the best of my  knowledge,  are  owned by the  Company,
directly  or  through  subsidiaries,  free and clear of any  security  interest,
mortgage,  pledge,  lien,  encumbrance,   claim  or  equity;  and  none  of  the
outstanding shares of capital stock of any Significant Subsidiary were issued in
violation of preemptive or other similar  rights of any  securityholder  of such
Significant Subsidiary.

     5. The  information  (i) in the  Annual  Report on Form 10-K  under  "Legal
Proceedings"     and     "Business--Competition,     Regulation     and     Rate
Matters--Regulation", "--State Utility Commission", "--Federal Energy Regulatory
Commission" and "--Securities and Exchange  Commission",  (ii) in the Prospectus
covering similar matters, if any, and (iii) in the Registration  Statement under
Item 15,  to the  extent  that  such  information  constitutes  matters  of law,
summaries  of  legal  matters,   the  Company's  charter  and  bylaws  or  legal
proceedings, or legal conclusions, has been reviewed by me and is correct in all
material respects.


                                      A-1





     6. To the  best of my  knowledge,  neither  of the  Company  nor any of its
Significant  Subsidiaries  is (i) in  violation  of its  charter  or  by-laws or
operating  agreement,  as the case may be,  or (ii) in  violation  of any law or
statute or any judgment, order, rule or regulation of any court or arbitrator or
governmental  or regulatory  authority,  except where such  violation  would not
result in a material adverse effect on the Company and its  subsidiaries,  taken
as a whole, and no default by the Company or any of its Significant Subsidiaries
exists  in  the  due  performance  or  observance  of any  material  obligation,
agreement,  covenant or condition contained in any agreement and instrument that
is described or referred to in the  Registration  Statement or the Prospectus or
filed or incorporated by reference as an exhibit to the Registration Statement.

     7. The execution,  delivery and performance of the Agreement, the Indenture
and  the  Notes,  the  consummation  of  the  transactions  contemplated  in the
Prospectus  (including  the  issuance  and sale of the  Notes and the use of the
proceeds  therefrom as described in the  Prospectus)  and the  compliance by the
Company  with its  obligations  thereunder  have  been  duly  authorized  by all
necessary  corporate action and do not and will not, whether with or without the
giving of notice or  passage  of time or both,  conflict  with or  constitute  a
breach of, or default  under,  or result in the  creation or  imposition  of any
lien,  charge or  encumbrance  upon any assets,  properties or operations of the
Company or any of its  Significant  Subsidiaries  pursuant to, any  agreement or
instrument  known to me, nor will such  action  result in any  violation  of the
provisions  of the charter or by-laws or  operating  agreement of the Company or
any of its  Significant  Subsidiaries  or any  applicable  law,  statute,  rule,
regulation,  judgment,  order,  writ or decree,  known to me, of any government,
government  instrumentality or court,  domestic or foreign,  having jurisdiction
over the Company or any of its Significant  Subsidiaries or any of their assets,
properties or operations.

     8. To the  best of my  knowledge,  except  as  otherwise  disclosed  in the
Registration Statement or the Prospectus, there is not pending or threatened any
action, suit,  proceeding,  inquiry or investigation to which the Company or any
of its Significant Subsidiaries is a party or to which the assets, properties or
operations  of the Company or any of its  Significant  Subsidiaries  is subject,
before or  brought  by any court or  governmental  agency or body,  domestic  or
foreign,  which might  reasonably  be  expected to result in a material  adverse
effect on the Company and its  Significant  Subsidiaries,  taken as a whole,  or
which might  reasonably  be  expected to  materially  and  adversely  affect the
assets,  properties  or  operations  of the  Company  or any of its  Significant
Subsidiaries,  the  performance by the Company or of its  obligations  under the
Agreement,  the Indenture,  or the Notes or the consummation of the transactions
contemplated in the Prospectus.

     9. All  descriptions  in the Prospectus of contracts and other documents to
which the  Company or any of its  subsidiaries  are a party are  accurate in all
material  respects;  and, to the best of my knowledge,  there are no franchises,
contracts,  indentures,  mortgages,  loan  agreements,  notes,  leases  or other
instruments  required  to  be  described  or  referred  to in  the  Registration
Statement or to be filed as exhibits to the  Registration  Statement  other than
those  described or referred to therein or filed or incorporated by reference as
exhibits thereto, and the descriptions thereof or references thereto are correct
in all material respects.


                                      A-2




     10. To the best of my knowledge,  there are no statutes or regulations that
are  required  to be  described  in the  Prospectus  that are not  described  as
required.

     11. The Registration Statement and the Prospectus,  excluding the documents
incorporated  by reference  therein,  and each  amendment or  supplement  to the
Registration  Statement and Prospectus,  excluding the documents incorporated by
reference therein,  as of their respective  effective or issue dates (other than
the financial  statements and supporting  schedules  included therein or omitted
therefrom  and the  Trustee's  Statement of  Eligibility  on Form T-1 (the "Form
T-1"), as to which no opinion is expressed), complied as to form in all material
respects with the requirements of the Securities Act.

     12. The documents  incorporated by reference in the Prospectus  (other than
the financial  statements and supporting  schedules  included therein or omitted
therefrom,  as to which no opinion is expressed),  when they were filed with the
Commission,  complied as to form in all material  respects with the requirements
of the Exchange Act.

     Nothing has come to such  counsel's  attention that would lead such counsel
to believe  that the  Registration  Statement  or any  post-effective  amendment
thereto  (except for (x) financial  statements,  supporting  schedules and other
financial and statistical  data included therein or omitted  therefrom,  (y) the
Form  T-1  and  (z)  the  information   related  to  estimated  proved  reserves
attributable  to certain oil and gas properties and estimates of future net cash
flows and  present  values  referred  to in the  Prospectus  under  the  caption
"Experts",  as to which such  counsel  makes no  statement),  at the date of the
Underwriting and Exchange Agreement, contained an untrue statement of a material
fact or  omitted  to state a  material  fact  required  to be stated  therein or
necessary to make the  statements  therein not misleading or that the Prospectus
or any amendment or  supplement  thereto  (except for (x) financial  statements,
supporting  schedules and other financial and statistical  data included therein
or  omitted  therefrom,  (y) the Form  T-1 and (z) the  information  related  to
estimated  proved  reserves  attributable  to certain oil and gas properties and
estimates  of  future  net cash  flows and  present  values  referred  to in the
Prospectus  under the  caption  "Experts",  as to which  such  counsel  makes no
statement),  at the time the Prospectus was issued, at the time any such amended
or  supplemented  prospectus  was  issued  or at the date  hereof,  included  or
includes an untrue  statement of a material  fact or omitted or omits to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading.

     The  opinion  of  counsel   described   above  shall  be  rendered  to  the
Underwriters at the request of the Company and shall so state therein.


                                      A-3






                                                                     EXHIBIT B-1

FORM OF OPINION OF SIMPSON  THACHER & BARTLETT LLP TO BE  DELIVERED  PURSUANT TO
                                  SECTION 6(h)

     1. The Company has been duly  incorporated  and is validly  existing and in
good standing as a  corporation  under the laws of the State of New York and has
full  corporate  power and authority to conduct its business as described in the
Registration Statement and Prospectus.

     2. The  Underwriting  and  Exchange  Agreement  has been  duly  authorized,
executed and delivered by the Company.

     3. The  Indenture has been duly  authorized,  executed and delivered by the
Company and duly  qualified  under the Trust  Indenture  Act of 1939, as amended
(the "Trust Indenture Act"),  and,  assuming that the Indenture is the valid and
legally binding obligation of the Trustee, the Indenture constitutes a valid and
legally  binding  obligation of the Company  enforceable  against the Company in
accordance with its terms.

     4. The Notes have been duly authorized,  executed and issued by the Company
and, assuming due  authentication  thereof by the Trustee,  constitute valid and
legally binding  obligations of the Company  enforceable  against the Company in
accordance with their terms and entitled to the benefits of the Indenture.

     5. The  statements  made in the  Prospectus  Supplement  under the  caption
"Description of the Notes" and the statements made in the Base Prospectus  under
the  caption  "Description  of Debt  Securities",  insofar  as they  purport  to
constitute  summaries of certain terms of contracts and other documents referred
to  therein,  constitute  accurate  summaries  of the  terms  of such  statutes,
contracts and other documents in all material respects.

     6.  No   consent,   approval,   authorization,   order,   registration   or
qualification of or with any federal or New York governmental agency or body or,
to our knowledge, any federal or New York court is required for the issuance and
sale of the Notes by the Company  and the  compliance  by the  Company  with the
provisions of the  Underwriting  and Exchange  Agreement,  the Indenture and the
Notes,  except for (A) the issuance of an  appropriate  order by the  Commission
under the Public Utility Holding Company Act, (B) the  registration of the Notes
under  the  Securities  Act and (C) such  consents,  approvals,  authorizations,
orders,   registrations  or  qualifications  as  may  be  required  under  state
securities  or Blue Sky  laws in  connection  with the sale of the  Notes by the
Underwriters.

     7. The Registration Statement has become effective under the Securities Act
and the Prospectus  was filed on March 30, 2005,  pursuant to Rule 424(b) of the
rules and  regulations of the Commission  under the Securities  Act, and, to our
knowledge,  no stop  order  suspending  the  effectiveness  of the  Registration
Statement has been issued or proceedings  for that purpose have been  instituted
or threatened by the Commission.

     8. Subject to the qualifications,  exceptions,  assumptions and limitations
therein, the statements set forth in the Prospectus Supplement under the caption
"Certain  United States Federal Income and Estate Tax  Consequences  to Non-U.S.
Holders",  insofar as they purport to constitute  summaries of matters of United
States  federal  tax law and  regulations  or  legal  conclusions  with  respect
thereto,  constitute  accurate summaries of the matters described therein in all
material respects.

     9. The Company is not, and after giving  effect to the offering and sale of
the Notes will not be, an "investment company" within the meaning of and subject
to regulation under the Investment Company Act of 1940, as amended.

     The opinions  set forth in  paragraphs 4 and 5 above are subject to (i) the
effects  of  bankruptcy,  insolvency,  fraudulent  conveyance,   reorganization,
moratorium  and other  similar laws relating to or affecting  creditors'  rights
generally, (ii) general equitable principles (whether considered in a proceeding
in  equity  or at law) and  (iii) an  implied  covenant  of good  faith and fair
dealing.

     The  opinion  of  counsel   described   above  shall  be  rendered  to  the
Underwriters at the request of the Company and shall so state therein.


                                       B-1




                                                                    EXHIBIT B-2

FORM OF LETTER OF SIMPSON  THACHER & BARTLETT  LLP TO BE  DELIVERED  PURSUANT TO
                                  SECTION 6(h)

     Such  counsel  shall (i)  advise  the  Underwriters  that the  Registration
Statement,  as of its  effective  date,  and  the  Prospectus,  as of its  date,
appeared,  on its face, to be appropriately  responsive in all material respects
with  the  requirements  of the  Securities  Act and the  applicable  rules  and
regulations of the Commission  thereunder,  except that such counsel may express
no  view  with  respect  to the  financial  statements  or  other  financial  or
statistical  data contained or  incorporated  by reference in such  Registration
Statement,  the  Prospectus  or the Exchange Act  Documents and (ii) nothing has
come to such  counsel's  attention  to cause such  counsel  to believe  that the
Registration  Statement  (including  the Exchange Act Documents on file with the
Commission on the date of filing of the Company's Annual Report on Form 10-K for
the  fiscal  year ended  December  31,  2004),  as of the date of filing of such
Annual Report,  contained any untrue  statement of a material fact or omitted to
state any material fact  required to be stated  therein or necessary in order to
make the statements therein not misleading or that the Prospectus (including the
Exchange  Act  Documents)  as of its date or as of the date hereof  contained or
contains any untrue  statement  of a material  fact or omitted or omits to state
any material  fact  necessary in order to make the  statements  therein,  in the
light of the  circumstances  under which they were made, not misleading,  except
that in each case such  counsel  need not express any belief with respect to the
financial  statements  or other  financial  or  statistical  data  contained  or
incorporated by reference in the Registration  Statement,  the Prospectus or the
Exchange Act Documents.

     For purposes of this letter,  "Exchange Act Documents"  means the Company's
Annual  Report on Form 10-K for the year ended  December  31, 2004 and all other
reports filed by the Company  pursuant to Section 13(a) or 15(d) of the 1934 Act
since the end of the fiscal year covered by such Annual Report.
