                 (b)      keep the Exchange Offer open for acceptance for a 
         period of not less than 30 calendar days after the date notice 
         thereof is mailed to the Holders (or longer if required by applicable 
         law) (such period referred to herein as the "Exchange Period");

                 (c)      utilize the services of the Depositary for the 
         Exchange Offer;

                 (d)      permit Holders to withdraw tendered Registrable 
         Securities at any time prior to 5:00 p.m. (Eastern Standard Time), on 
         the last business day of the Exchange Period, by sending to the 
         institution specified in the notice, a telegram, telex, facsimile
         transmission or letter setting forth the name of such Holder, the 
         principal amount of Registrable Securities delivered for exchange, and
         a statement that such Holder is withdrawing his election to have such 
         Securities exchanged;

                 (e)      notify each Holder that any Registrable Security not 
         tendered will remain outstanding and continue to accrue interest, but 
         will not retain any rights under this Agreement (except in the case of
         certain rights retained by the Initial Purchasers and Participating 
         Broker-Dealers as provided herein); and 

                 (f)      otherwise comply in all material respects with all 
         applicable laws relating to the Exchange Offer.

                 As soon as practicable after the close of the Exchange Offer, 
         Company shall:

                 (i)      accept for exchange all Registrable Securities duly  
         tendered and not validly withdrawn pursuant to the Exchange Offer in
         accordance with the terms of the Exchange Offer Registration Statement
         and the letter of transmittal which shall be an exhibit thereto;

                 (ii)     deliver or cause to be delivered all Registrable 
         Securities so accepted for exchange to the Trustee for cancellation;
         and

                 (iii)    cause the Trustee promptly to authenticate and 
         deliver Exchange Securities to each Holder of Registrable Securities
         so accepted for exchange in a principal amount equal to the principal
         amount of the Registrable Securities of such Holder so accepted for
         exchange.

                 Interest on each Exchange Security will accrue from the day
after the last date on which interest was paid on the Registrable Securities
surrendered in exchange therefor or, if no interest has been paid on the
Registrable Securities, from the date of original issuance.  The Exchange Offer
shall not be subject to any conditions, other than (i) that the Exchange Offer,
or the making of any exchange by a Holder, does not violate applicable law or
any applicable interpretation of the staff of the SEC, (ii) the due tendering
of Registrable Securities in accordance with the Exchange Offer, (iii) that
each Holder of Registrable Securities exchanged in the Exchange Offer shall
have represented that all Exchange Securities to be received by it shall be
acquired in the ordinary course of its business and that at the time of the
consummation of the Exchange Offer it shall have no arrangement or
understanding with any person to participate in the distribution (within the
meaning of the 1933 Act) of the Exchange Securities and shall have made such
other representations as may be reasonably necessary under applicable SEC
rules, regulations or interpretations to render the use of Form S-4 or other
appropriate form under the 1933 Act available, (iv) that no action or
proceeding shall have been instituted or threatened in any court or by or
before any governmental agency with respect to the Exchange Offer, (v) that
there shall not have been adopted or enacted any law, statute, rule or
regulation, (vi) that there shall not have been declared by United States
federal or New York state authorities a banking moratorium, (vii) that trading
on the New York Stock Exchange or generally in the United States
over-the-counter market shall not have been suspended by order of the SEC or
any other governmental authority and (viii) such other conditions as may be
reasonably acceptable to Merrill Lynch, in each of clauses (iv) through (viii),
which, in the Company's judgment, would reasonably be expected to impair the
ability of the Company to proceed with the Exchange Offer.  The Company shall
inform the Initial Purchasers of the names and addresses of the Holders to whom
the Exchange Offer is made, and the Initial Purchasers shall have the right to
contact such Holders and otherwise facilitate the tender of Registrable
Securities in the Exchange Offer.

                 2.2      Shelf Registration.  (i) If, because of any changes
in law, SEC rules or regulations or applicable interpretations thereof by the
staff of the SEC, the Company is not permitted to effect the Exchange Offer as
contemplated by Section 2.1 hereof, (ii) if for any other reason the Exchange
Offer Registration Statement is not declared effective within 150 days
following the Closing Date or the Exchange Offer is not consummated within 180
days after the Closing Date, (iii)  if a Holder is advised by counsel that it
is not permitted by Federal securities laws or SEC policy to participate in the
Exchange Offer or does not receive Exchange Securities that are fully tradeable
pursuant to the Exchange Offer without restriction or limitation as to holding
period or volume or (iv) upon the request of the Initial Purchasers acquiring a
majority of the initial aggregate principal amount of the Registrable
Securities (but only with respect to any Registrable Securities which the
Initial Purchasers acquired directly from the Company)then in case of each of
clauses (i) through (iv) the Company shall, at their cost:

                 (a)      As promptly as practicable, file with the SEC, and
         thereafter shall use its reasonable best efforts to cause to be
         declared effective as promptly as practicable but no later than 210
         days after the Closing Date, a Shelf Registration Statement relating
         to the offer





                                     -6-
   8
         and sale of the Registrable Securities by the Holders from time to
         time in accordance with the methods of distribution elected by the
         Majority Holders participating in the Shelf Registration and set forth
         in such Shelf Registration Statement.

                 (b)      Use its reasonable best efforts to keep the Shelf
         Registration Statement continuously effective in order to permit the
         Prospectus forming part thereof to be usable by Holders for a period
         of two years from the Closing Date, or for such shorter period that
         will terminate when all Registrable Securities covered by the Shelf
         Registration Statement (i) have been sold pursuant thereto, (ii) cease
         to be outstanding or (iii) become freely tradeable without restriction
         or limitation as to holding period or volume; provided, however, that
         the Company shall not be obligated to keep the Shelf Registration
         Statement effective if (A) any event occurs or facts are discovered
         which make any statement made in such Registration Statement or the
         related Prospectus untrue in any material respect or which require the
         making of any changes in such Registration Statement or Prospectus in
         order to make the Statements therein not misleading; (B) the Company
         determines, in its reasonable judgment, upon advice of counsel, as
         authorized by a resolution of its Board of Directors, that the
         continued effectiveness and useability of the Shelf Registration
         Statement would (x) require the disclosure of material information,
         which the Company has a bona fide business reason for preserving as
         confidential, or (y) interfere with any financing, acquisition,
         corporate reorganization or other material transaction involving the
         Company or any of its subsidiaries, and provided further, that the
         failure to keep the Shelf Registration Statement effective and usable
         for offers and sales of Registrable Securities for such reasons shall
         last no longer than 45 days in any 12-month period (whereafter a
         Registration Default, as hereinafter defined, shall occur), and (B)
         the Company thereafter complies as promptly as reasonably practicable
         with the requirements of Section 3(k) hereof, if applicable.  Any such
         period during which the Company is excused from keeping the Shelf
         Registration Statement effective and usable for offers and sales of
         Registrable Securities is referred to herein as a "Suspension Period";
         a Suspension Period shall commence on and include the date that the
         Company gives notice to the Holders that the Shelf Registration
         Statement is no longer effective or the prospectus included therein is
         no longer usable for offers and sales of Registrable Securities as a
         result of the application of the proviso of the foregoing sentence and
         shall end on the earlier to occur of (1) the date on which each seller
         of Registrable Securities covered by the Shelf Registration Statement
         either receives the copies of the supplemented or amended prospectus
         contemplated by Section 3(k) hereof or is advised in writing by the
         Company that use of the prospectus may be resumed and (2) the
         expiration of 45 days in any 12-month period during which one or more
         Suspension Periods has been in effect.  The Company shall extend the
         relevant period referred to above during which it is required to keep
         affective the Shelf Registration Statement (or the period during which
         Participating Broker-Dealers are entitled to use the prospectus
         included in the Exchange Offer Registration Statement in connection
         with the resale of the Exchange Securities, as the case may be) by the
         number of days during the period from and including the date of the
         giving of such notice to and including the date which is the earlier
         to occur as described in the preceding sentence.

                 (c)      Notwithstanding any other provisions hereof, use
         their reasonable best efforts to ensure that (i) any Shelf
         Registration Statement and any amendment thereto and any Prospectus
         forming part thereof and any supplement thereto complies in all
         material respects with the 1933 Act and the rules and regulations
         thereunder, (ii) any Shelf Registration Statement and any amendment
         thereto does not, when it becomes effective, contain an untrue
         statement of a material fact or omit to state a material fact required
         to be stated therein or necessary to make the statements therein not
         misleading and (iii) any Prospectus forming part of any Shelf
         Registration Statement, and any supplement to such Prospectus (as
         amended or supplemented from time to time), does not include an untrue
         statement of a material fact or omit to state a material fact
         necessary in order to make the statements, in light of the
         circumstances under which they were made, not misleading.

                 The Company further agrees, if necessary, to supplement or 
amend the Shelf Registration Statement, as required by Section  3(b) below, and
to furnish to the Holders of Registrable Securities copies of any such
supplement or amendment promptly after its being used or filed with the SEC.

                 2.3      Expenses.  The Company shall pay all Registration 
Expenses in connection with the registration pursuant to Section 2.1 or 2.2. 
Each Holder shall pay all underwriting discounts and commissions and transfer
taxes, if any, relating to the sale or disposition of such Holder's Registrable
Securities pursuant to the Shelf Registration Statement.

                 2.4      Effectiveness.  (a) The Company will be deemed not 
to have used its reasonable best efforts to cause the Exchange Offer
Registration Statement or the Shelf Registration Statement, as the case may be,
to become, or to remain, effective during the requisite period if the Company
voluntarily takes any action that would, or omits to take any action which
omission would, result in any such Registration Statement not being declared
effective or in the holders of Registrable Securities covered thereby not being
able to exchange or offer and sell such Registrable Securities during that
period as and to the extent contemplated hereby, unless such action is required
by applicable law.

                 (b)      An Exchange Offer Registration Statement pursuant to
Section 2.1 hereof or a Shelf Registration Statement pursuant to Section 2.2
hereof will not be deemed to have become effective unless it has been declared
effective by the SEC; provided, however, that if, after it has been declared
effective, the offering of Registrable Securities pursuant to a Shelf
Registration Statement is interfered with by any stop order, injunction or
other order or requirement of the SEC or any other governmental agency or
court, such Registration Statement will be deemed not to have remained
effective during the period of such interference, until the offering of
Registrable Securities pursuant to such Registration Statement may legally
resume.

                 2.5      Interest.  The Indenture executed in connection
with the Securities will provide that in the event that either (a) the Exchange
Offer Registration Statement is not filed with





                                     -8-
   10
The Commission on or prior to the 90th calendar day following the Closing Date,
(b) the Exchange Offer Registration Statement has not been declared effective
on or prior to the 150th calendar day following the Closing Date, (c) the
Exchange Offer is not consummated on or prior to the 180th calendar day
following the Closing Date, (d) a required Shelf Registration Statement is not
declared effective on or prior to the 210th calendar day following the Closing
Date or (e) the Exchange Offer Registration Statement or Shelf Registration
Statement is filed and declared effective but shall thereafter be withdrawn by
the Company or becomes subject to an effective stop order suspending the
effectiveness of such registration statement, except as specifically permitted
by Section 2.2(b) hereof, without being succeeded immediately by an additional
registration statement filed and declared effective (each such event referred
to in clauses (a) through (e) above, a "Registration Default"), the interest
rate borne by the Securities shall be increased by one- quarter of one percent
(0.25%) per annum following such Registration Default, with an aggregate
maximum increase in the interest rate equal to one-quarter of one percent
(0.25%) per annum; provided, however, that if the Exchange Offer Registration
Statement is not declared effective on or prior to the 150th calendar day
following the Closing Date and the Company shall request holders of Securities
to provide information for inclusion in the Shelf Registration Statement, then
Securities owned by Holders who do not deliver such information to the Company
or who do not provide comments on the Shelf Registration Statement when
requested by the Company will not be entitled to any such increase in the
interest rate for any day after the 180th day following the Closing Date.
Following the cure of all Registration Defaults, the accrual of such additional
interest will cease and the interest rate will revert to the original rate.

                 2.6      Specific Enforcement.  Without limiting the remedies
available to the Initial Purchasers and the Holders, the Company acknowledges
that any failure by the Company to comply with their obligations under Sections
2.1 and 2.2 hereof may result in material irreparable injury to the Initial
Purchasers or the Holders for which there is no adequate remedy at law, that it
will not be possible to measure damages for such injuries precisely and that,
in the event of any such failure, the Initial Purchasers or any Holder may, to
the extent permitted by law, obtain such relief as may be required to
specifically enforce the Company's obligations under Section 2.1 and Section
2.2 hereof.

                 3.       Registration Procedures.

                 In connection with the obligations of the Company with respect
to Registration Statements pursuant to Sections 2.1 and 2.2 hereof, the Company
shall:

                 (a)      prepare and file with the SEC a Registration
         Statement, within the relevant time period specified in Section 2, on

         selected by the Company, (ii) shall, in the case of a Shelf
         Registration, be available for the sale of the Registrable Securities
         by the selling Holders thereof, (iii) shall comply as to form in all
         material respects with the requirements of the applicable form and
         include or incorporate by reference all financial statements required
         by the SEC to be filed therewith or incorporated by reference therein,
         and (iv) shall comply in all respects with the





                                     -9-
   11
         requirements of Regulation S-T under the 1933 Act, and use their
         reasonable best efforts to cause such Registration Statement to become
         effective and remain effective in accordance with Section 2 hereof;

                 (b)      prepare and file with the SEC such amendments and
         post-effective amendments to each Registration Statement as may be
         necessary under applicable law to keep such Registration Statement
         effective for the applicable period; and cause each Prospectus to be
         supplemented by any required prospectus supplement, and as so
         supplemented to be filed pursuant to Rule 424 under the 1933 Act and
         comply with the provisions of the 1933 Act applicable to them with
         respect to the disposition of all securities covered by each
         Registration Statement during the applicable period to the extent
         allowed by law and reasonably practicable to the Company with the
         intended method or methods of distribution by the selling Holders
         thereof;

                 (c)      in the case of a Shelf Registration, (i) notify each
         Holder of Registrable Securities, at least five business days prior to
         filing, that a Shelf Registration Statement with respect to the
         Registrable Securities is being filed and advising such Holders that
         the distribution of Registrable Securities will be made in accordance
         with the method selected by the Majority Holders participating in the
         Shelf Registration; (ii) furnish to each Holder of Registrable
         Securities and to each underwriter of an underwritten offering of
         Registrable Securities, if any, without charge, as many copies of each
         Prospectus, including each preliminary Prospectus, and any amendment
         or supplement thereto and such other documents as such Holder or
         underwriter may reasonably request, including financial statements and
         schedules and, if the Holder so requests, all exhibits in order to
         facilitate the public sale or other disposition of the Registrable
         Securities; and (iii) hereby consent to the use of the Prospectus or
         any amendment or supplement thereto by each of the selling Holders of
         Registrable Securities in connection with the offering and sale of the
         Registrable Securities covered by the Prospectus or any amendment or
         supplement thereto;

                 (d)      use its reasonable best efforts to register or
         qualify the Registrable Securities under all applicable state
         securities or "blue sky" laws of such jurisdictions as any Holder of
         Registrable Securities covered by a Registration Statement and the
         managing underwriter of an underwritten offering of Registrable
         Securities shall reasonably request by the time the applicable
         Registration Statement is declared effective by the SEC, and do any
         and all other acts and things which may be reasonably necessary or
         advisable to enable each such Holder and underwriter to consummate the
         disposition in each such jurisdiction of such Registrable Securities
         owned by such Holder, provided, however, that the Company shall not be
         required to (i) qualify as a foreign corporation or as a dealer in
         securities in any jurisdiction where it would not otherwise be
         required to qualify but for this Section 3(d), or (ii) take any action
         which would subject it to general service of process or taxation in
         any such jurisdiction where it is not then so subject;

                 (e)      notify promptly each Holder of Registrable Securities
         under a Shelf Registration or any Participating Broker-Dealer who has
         notified the Company that it is utilizing the Exchange Offer
         Registration Statement as provided in paragraph (f) below and, if
         requested by such Holder or Participating Broker-Dealer, confirm such
         advice in writing promptly (i) when a Registration Statement has
         become effective and when any post-effective amendments and
         supplements thereto become effective, (ii) of any request by the SEC
         or any state securities authority for post-effective amendments and
         supplements to a Registration Statement and Prospectus or for
         additional information after the Registration Statement has become
         effective, (iii) of the issuance by the SEC or any state securities
         authority of any stop order suspending the effectiveness of a
         Registration Statement or the initiation of any proceedings for that
         purpose, (iv) in the case of a Shelf Registration, if, between the
         effective date of a Registration Statement and the closing of any sale
         of Registrable Securities covered thereby, the representations and
         warranties of the Company contained in any underwriting agreement,
         securities sales agreement or other similar agreement, if any,
         relating to such sale cease to be true and correct in all material
         respects, (v) of the happening of any event or the discovery of any
         facts during the period a Shelf Registration Statement is effective
         which makes any statement made in such Registration Statement or the
         related Prospectus untrue in any material respect or which requires
         the making of any changes in such Registration Statement or Prospectus
         in order to make the statements therein not misleading and (vi) of the
         receipt by the Company of any notification with respect to the
         suspension of the qualification of the Registrable Securities or the
         Exchange Securities, as the case may be, for sale in any jurisdiction
         or the initiation or threatening of any proceeding for such purpose;

                 (f)      (A)     in the case of the Exchange Offer
         Registration Statement (i) include in the Exchange Offer Registration
         Statement a section entitled "Plan of Distribution" which section
         shall be reasonably acceptable to the Initial Purchasers, and which
         shall contain a summary statement of the positions taken or policies
         made by the staff of the SEC with respect to the potential
         "underwriter" status of any broker-dealer that holds Registrable
         Securities acquired for its own account as a result of market-making
         activities or other trading activities and that will be the beneficial
         owner (as defined in Rule l3d-3 under the Exchange Act) of Exchange
         Securities to be received by such broker-dealer in the Exchange Offer,
         whether such positions or policies have been publicly disseminated by
         the staff of the SEC or such positions or policies, in the reasonable
         judgment of the Initial Purchasers and its counsel, represent the
         prevailing views of the staff of the SEC, including a statement that
         any such broker-dealer who receives Exchange Securities for
         Registrable Securities pursuant to the Exchange Offer may be deemed a
         statutory underwriter and must deliver a prospectus meeting the
         requirements of the 1933 Act in connection with any resale of such
         Exchange Securities, (ii) furnish to each Participating Broker-Dealer
         who has delivered to the Company the notice referred to in Section
         3(e), without charge, as many copies of each Prospectus included in
         the Exchange Offer Registration Statement, including any preliminary
         prospectus, and any amendment or supplement thereto, as such
         Participating Broker-Dealer may reasonably request, (iii) hereby
         consents to the use of the Prospectus forming part of the





                                    -11-
   13
         Exchange Offer Registration Statement or any amendment or supplement
         thereto, by any person subject to the prospectus delivery requirements
         of the SEC, including all Participating Broker-Dealers, in connection
         with the sale or transfer of the Exchange Securities covered by the
         prospectus or any amendment or supplement thereto, and (iv) include in
         the transmittal letter or similar documentation to be executed by an
         exchange offeree in order to participate in the Exchange Offer (x) the
         following provision:

                 "If the exchange offeree is a broker-dealer holding
                 Registrable Securities acquired for its own account as a
                 result of market-making activities or other trading
                 activities, it will deliver a prospectus meeting the
                 requirements of the 1933 Act in connection with any resale of
                 Exchange Securities received in respect of such Registrable
                 Securities pursuant to the Exchange Offer" and

         (y) a statement to the effect that by a broker-dealer making the
         acknowledgment described in clause (x) and by delivering a Prospectus
         in connection with the exchange of Registrable Securities, the
         broker-dealer will not be deemed to admit that it is an underwriter
         within the meaning of the 1933 Act and

                          (B)     to the extent any Participating Broker-Dealer
         participates in the Exchange Offer, the Company shall use its
         reasonable best efforts to cause to be delivered at the request of an
         entity representing the Participating Broker-Dealers (which entity
         shall be Merrill Lynch or another Initial Purchaser) (A) a "cold
         comfort" letter addressed to the Participating Broker-Dealers from the
         Company's independent certified public accountants with respect to the
         Prospectus in the Exchange Offer Registration Statement in the form
         existing on the last date for which exchanges are accepted pursuant to
         the Exchange Offer and (B) an opinion of counsel to the Company
         addressed to the Participating Broker-Dealers in substantially the
         form attached hereto as Exhibit A relating to the Exchange Securities;

         Holders of Registrable Securities copies of any comment letters
         received from the SEC or any other request by the SEC or any state
         securities authority for amendments or supplements to a Registration
         Statement and Prospectus or for additional information;

                 (h)      make every reasonable effort to obtain the withdrawal
         of any order  suspending the effectiveness of a Registration Statement
         as soon as practicable and provide prompt notice to one firm of legal
         counsel for the Holders of the withdrawal of any such order;

                 (i)      in the case of a Shelf Registration, furnish to each
         Holder of Registrable Securities, and each underwriter, if any,
         without charge, at least one conformed copy of each





                                    -12-
   14
         Registration Statement and any post-effective amendment thereto,
         including financial statements and schedules (without documents
         incorporated therein by reference or any exhibits thereto, unless
         requested);

                 (j)      in the case of a Shelf Registration, cooperate with
         the selling Holders of Registrable Securities to facilitate the timely
         preparation and delivery of certificates representing Registrable
         Securities to be sold and not bearing any restrictive legends; and
         enable such Registrable Securities to be in such denominations
         (consistent with the provisions of the Indenture) and registered in
         such names as the selling Holders or the underwriters, if any, may
         reasonably request at least three business days prior to the closing
         of any sale of Registrable Securities;

                 (k)      in the case of a Shelf Registration, upon the Company
         becoming aware of the occurrence of any event or the discovery of any
         facts, each as contemplated by Section 3(e)(v) hereof, use their
         reasonable best efforts to prepare a supplement or post-effective
         amendment to the Registration Statement or the related Prospectus or
         any document incorporated therein by reference or file any other
         required document so that, as thereafter delivered to the purchasers
         of the Registrable Securities or Participating Broker-Dealers, such
         Prospectus will not contain at the time of such delivery any untrue
         statement of a material fact or omit to state a material fact
         necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading;

                 (l)      obtain a CUSIP number for all Exchange Securities or
         Registrable Securities, as the case may be, not later than the
         effective date of a Registration Statement, and provide the Trustee
         with a certificate or certificates for the Exchange Securities or the
         Registrable Securities, as the case may be, in a form eligible for
         deposit with the Depositary and consistent with the procedures to be
         used by the Depositary;

                 (m)      unless the Indenture, as it relates to the Exchange
         Securities or the Registrable Securities, as the case may be, has
         already been so qualified, use its reasonable best efforts to (i)
         cause the Indenture to be qualified under the Trust Indenture Act of
         1939 (the "TIA") in connection with the registration of the Exchange
         Securities or Registrable Securities, as the case may be, (ii)
         cooperate with the Trustee and the Holders to effect such changes to
         the Indenture as may be required for the Indenture to be so qualified
         in accordance with the terms of the TIA and (iii) execute, and use its
         reasonable best efforts to cause the Trustee to execute, all documents
         as may be required to effect such changes, and all other forms and
         documents required to be filed with the SEC to enable the Indenture to
         be so qualified in a timely manner;

                 (n)      in the case of a Shelf Registration, take all
         customary and appropriate actions reasonably required (including those
         reasonably requested by the Majority Holders) in order to expedite or
         facilitate the disposition of the Registrable Securities registered
         thereby.  If requested as set forth below, the Company agrees that it
         will in good faith negotiate the terms





                                    -13-
   15
         of an underwriting agreement, which shall be in form and scope as is
         customary for similar offerings of debt securities with similar credit
         ratings (including, without limitation, representations and warranties
         to the underwriters) and shall otherwise be reasonably satisfactory to
         the Company and the managing underwriters; and:

                          (i)     if requested by the managing underwriters,
         obtain opinions of counsel to the Company (which counsel shall be
         reasonably satisfactory to the managing underwriters) addressed to
         such underwriters, covering the matters customarily covered in
         opinions requested in underwritten sales of securities in the form
         agreed upon by such counsel and counsel to the managing underwriters;

                          (ii)    if requested by the managing underwriters,
         obtain a "cold comfort" letter and an update thereto not later than
         two weeks after the date of the original letter (or if not available
         under applicable accounting pronouncements or standards, a single
         "procedures" letter and a single update thereto) from the Company's
         independent certified public accountants addressed to the underwriters
         named in the underwriting agreement and use its reasonable best
         efforts to have such letter addressed to the selling Holders of
         Registrable Securities (provided, however, that such letter need not
         be addressed to any Holders to whom, in the reasonable opinion of the
         Company's independent certified public accountants, addressing such
         letter is not permissible under applicable accounting standards), such
         letters to be in customary form and covering matters of the type
         customarily covered in "cold comfort" (or "procedures") letters to
         underwriters in connection with similar underwritten offerings; and

                          (iii)   deliver such documents and certificates as
         may be reasonably requested and as are customarily delivered in
         similar underwritten offerings.

                          Notwithstanding anything herein to the contrary, the
         Company shall have no obligation to enter into any underwriting
         agreement or permit an underwritten offering of Registrable Securities
         unless a request therefor shall have been received from the Majority
         Holders within ten business days of the date of the notice from the
         Company as required by Section 3(c).  In the case of such a request
         for an underwritten offering, the Company shall provide reasonable
         advance written notice to the Holders of all Registrable Securities of
         such proposed underwritten offering.  Such notice shall (A) offer each
         such Holder the right to participate in such underwritten offering
         (but may indicate that whether or not all Registrable Securities are
         included will be at the discretion of the underwriters), (B) specify a
         date, which shall be no earlier than ten business days following the
         date of such notice, by which such Holder must inform the Company of
         its intent to participate in such underwritten offering and (C)
         include the instructions such Holder must follow in order to
         participate in such underwritten offering;

                          (o)     in the case of a Shelf Registration, and to
         the extent customary in connection with a "due diligence"
         investigation for an offering of debt securities with a similar credit





                                    -14-
   16
                 rating to that of the Registrable Securities, make available
                 for inspection by representatives appointed by the Majority
                 Holders and any underwriters participating in any disposition
                 pursuant to a Shelf Registration Statement and one firm of

                 requested by any such representative, underwriter or counsel
                 in connection with a Registration Statement, and make such
                 representatives of the Company available for discussion of
                 such documents as shall be reasonably requested by the Initial

                          (p)     (i)      in the case of an Exchange Offer
                 Registration Statement, a reasonable time prior to the filing
                 of any Exchange Offer Registration Statement, any Prospectus

                 reasonable time prior to filing any Shelf Registration
                 Statement, any Prospectus forming a part thereof, any
                 amendment to such Shelf Registration Statement or amendment or
                 supplement to such Prospectus, provide copies of such document
                 to Merrill Lynch, one firm of legal counsel appointed by the

                 make such changes in any such document prior to the filing
                 thereof as Merrill Lynch, such one firm of legal counsel for
                 the Holders, such managing underwriters or their counsel may
                 reasonably request and not file any such document in a form to
                 which Merrill Lynch, such one firm of legal counsel for the
                 Holders, such managing underwriters or their counsel may
                 reasonably object and make the representatives of the Company
                 available for discussion of such document as shall be
                 reasonably requested by Merrill Lynch, such one firm of legal
                 counsel for the Holders, such managing underwriters or their
                 counsel.

                          (q)     in the case of a Shelf Registration, use its
                 reasonable best efforts to cause the Registrable Securities to
                 be rated by the appropriate rating agencies, if so requested
                 by the 





                                      -15-
   17
                 Majority Holders, or if requested by the Majority Holders, or
                 by the managing underwriters of an underwritten offering of
                 Registrable Securities, if any, unless the Exchange Securities
                 or the Registrable Securities, as the case may be, are already
                 so rated or unless the Company has obtained such ratings for
                 its long-term debt securities generally;

                          (r)     otherwise use its reasonable best efforts to
                 comply with all applicable rules and regulations of the SEC
                 and make available to its security holders, as soon as
                 reasonably practicable, an earnings statement covering at
                 least 12 months which shall satisfy the provisions of Section
                 11(a) of the 1933 Act and Rule 158 thereunder;

                          (s)     cooperate and assist in any filings required
                 to be made with the NASD and, in the case of a Shelf
                 Registration, in the performance of any due diligence
                 investigation by any managing underwriter and its counsel
                 (including any "qualified independent underwriter" that is
                 required to be retained in accordance with the rules and
                 regulations of the NASD); and

                          (t)     upon consummation of an Exchange Offer,
                 obtain a customary opinion of counsel to the Company addressed
                 to the Trustee for the benefit of all Holders of Registrable
                 Securities participating in the Exchange Offer, and which
                 includes an opinion that (i) the Company has duly authorized,
                 executed and delivered the Exchange Securities and the related
                 indenture, and (ii) each of the Exchange Securities and
                 related indenture constitute a legal, valid and binding
                 obligation of the Company, enforceable against the Company in
                 accordance with its respective terms (with customary
                 exceptions).

                 In the case of a Shelf Registration Statement, the Company may
         (as a condition to such Holder's participation in the Shelf
         Registration) require each Holder of Registrable Securities to furnish
         to the Company such information regarding the Holder and the proposed
         distribution by such Holder of such Registrable Securities as the
         Company may from time to time reasonably request in writing.

                 In the case of a Shelf Registration Statement, each Holder
         agrees and in the case of the Exchange Offer Registration Statement,
         each Participating Broker-Dealer agrees that, (i) upon receipt of any
         notice from the Company of the happening of any event or the discovery
         of any facts, each of the kind described in Section 3(e)(v) hereof or
         (ii) the Company determines, in its reasonable judgment, upon advice
         of counsel, as authorized by a resolution of its Board of Directors,
         that the continued effectiveness and usability of the Shelf
         Registration Statement would (x) require the disclosure of material
         information, which the Company has a bona fide business reason for
         preserving as confidential, or (y) interfere with any financing,
         acquisition, corporate reorganization or other material transaction
         involving the Company or any of its subsidiaries, such Holder or
         Participating Broker-Dealer, as the case may be, will forthwith
         discontinue disposition of Registrable Securities pursuant to such
         Registration Statement until the receipt by such Holder or
         Participating Broker-Dealer, as the case may be, of (A) in the case of
         clause (i) above, the copies of the supplemented or amended Prospectus
         contemplated by Section 3(k) hereof, and, if so directed by





                                    -16-
   18
         the Company, such Holder will deliver to the Company (at its expense)
         all copies in its possession of the Prospectus covering such
         Registrable Securities current at the time of receipt of such notice,
         or (B) in the case of clause (ii) above, notice in writing from the
         Company that such Holder may resume disposition of Registrable
         Securities pursuant to such Registration Statement.  If the Company
         shall give any such notice described in clause (i) above to suspend
         the disposition of Registrable Securities pursuant to a Registration
         Statement as a result of the happening of any event or the discovery
         of any facts, each of the kind described in Section 3(e)(v) hereof,
         the Company  shall be deemed to have used its best efforts to keep
         such Registration Statement effective during such period of suspension
         provided that the Company shall use its reasonable best efforts to
         file and have declared effective (if an amendment) as soon as
         practicable an amendment or supplement to such Registration Statement
         and shall extend the period during which such Registration Statement
         shall be maintained effective pursuant to this Agreement by the number
         of days during the period from and including the date of the giving of
         such notice to and including the date when the Holders shall be
         entitled to resume such dispositions pursuant to this paragraph.

                      If any of the Registrable Securities covered by any Shelf
         Registration Statement are to be sold in an underwritten offering, the
         underwriter or underwriters and manager or managers that will manage
         such offering will be selected by the Company and shall be acceptable
         to the Majority Holders.  No Holder of Registrable Securities may
         participate in any underwritten offering hereunder unless such Holder
         (a) agrees to sell such Holder's Registrable Securities on the basis
         provided in any underwriting arrangements approved by the persons
         entitled hereunder to approve such arrangements and (b) completes and
         executes all questionnaires, powers of attorney, indemnities,
         underwriting agreements and other documents required under the terms
         of such underwriting arrangements.

                      (4)      Indemnification; Contribution.

                      (a)     The Company shall indemnify and hold harmless the
                 Initial Purchasers, each Holder, (in its capacity as a
                 participant in any Exchange Offer or Shelf Registration
                 transaction), each Participating Broker-Dealer, each Person
                 who participates as an underwriter (any such Person being an
                 "Underwriter") and each Person, if any, who controls any
                 Holder or Underwriter within the meaning of Section 15 of the
                 1933 Act or Section 20 of the 1934 Act as follows:

                      (i)     against any and all loss, liability, claim, damage
                 and expense whatsoever, as incurred, arising out of any untrue
                 statement or alleged untrue statement of a material fact
                 contained in any Registration Statement (or any amendment or
                 supplement thereto) pursuant to which Exchange Securities or
                 Registrable Securities were registered under the 1933 Act,
                 including all documents incorporated therein by reference, or
                 the omission or alleged omission therefrom of a material fact
                 required to be stated therein or necessary to make the
                 statements therein not misleading, or arising out of any
                 untrue statement or alleged untrue statement of a material
                 fact contained in any Prospectus (or any amendment or
                 supplement thereto) or the omission or alleged omission
                 therefrom of a material fact necessary in order





                                    -17-
   19
         to make the statements therein, in the light of the circumstances
         under which they were made, not misleading;

                 (ii)     against any and all loss, liability, claim, damage
         and expense whatsoever, as incurred, to the extent of the aggregate
         amount paid in settlement of any litigation, or any investigation or
         proceeding by any governmental agency or body, commenced or
         threatened, or of any claim whatsoever based upon any such untrue
         statement or omission, or any such alleged untrue statement or
         omission; provided that (subject to Section 4(d) below) any such
         settlement is effected with the written consent of the Company; and

                 (iii)    subject to Section 4(c) below, against any and all
         expense whatsoever, as incurred (including the fees and disbursements
         of counsel chosen by Merrill Lynch, or in the event that Merrill Lynch
         is not an indemnified party, by a majority of the indemnified
         parties), reasonably incurred in investigating, preparing or defending
         against any litigation, or any investigation or proceeding by any
         governmental agency or body, commenced or threatened, or any claim
         whatsoever based upon any such untrue statement or omission, or any
         such alleged untrue statement or omission, to the extent that any such
         expense is not paid under subparagraph (i) or (ii) above;

provided, however, that the indemnity agreement in this subsection 4(a) shall 
not apply to any loss, liability, claim, damage or expense to the extent 
arising out of any untrue statement or omission made in reliance upon and in 
corconformity with written information furnished to the Company by the Initial 
Purchasers, such Holder or underwriter expressly for use in a Registration 
Statement (or any amendment the thereto) or any Prospectus (or any amendment or
supplement thereto).

                 (b)      Each Holder severally, but not jointly, agrees to
         indemnify and hold harmless the Company, the Initial Purchasers, each
         Underwriter and the other selling Holders, and each of their
         respective directors and officers, and each Person, if any, who
         controls the Company, the Initial Purchasers, any Underwriter or any
         other selling Holder within the meaning of Section 15 of the 1933 Act
         or Section 20 of the 1934 Act, against any and all loss, liability,
         claim, damage and expense described in the indemnity contained in
         Section 4(a) hereof, as incurred, but only with respect to untrue
         statements or omissions, or alleged untrue statements or omissions,
         made in the Shelf Registration Statement (or any amendment thereto) or
         any Prospectus included therein (or any amendment or supplement
         thereto) in reliance upon and in conformity with written information
         furnished to the Company expressly for use in the Shelf Registration
         Statement (or any amendment thereto) or such Prospectus (or any
         amendment or supplement thereto); provided, however, that no such
         Holder shall be liable for any claims hereunder in excess of the
         amount of net proceeds received by such Holder from the sale of
         Registrable Securities pursuant to such Shelf Registration Statement.

                                      -18-
   20

                 (c)      Each indemnified party shall give notice as promptly
         as reasonably practicable to each indemnifying party of any action
         commenced against it in respect of which indemnity may be sought
         hereunder, but failure to so notify an indemnifying party shall not
         relieve such indemnifying party from any liability hereunder to the
         extent it is not materially prejudiced as a result thereof and in any
         event shall not relieve it from any liability which it may have
         otherwise than on account of this indemnity agreement. 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; provided, however, that if the defendants in
         any such action include both the indemnified party and the
         indemnifying party and the indemnified party shall have reasonably
         concluded that there may be one or more legal defenses available to it
         and/or other indemnified parties which are different from or
         additional to those available to the indemnifying party, the
         indemnifying party shall not have the right to direct the defense of
         such action on behalf of such indemnified party or parties and such
         indemnified party or parties shall have the right to select separate
         counsel to defend such action on behalf of such indemnified party or
         parties.  After notice from the indemnifying party to such indemnified
         party of its election so to assume the defense thereof and approval by
         such indemnified party of counsel appointed to defend such action, the
         indemnifying party will not be liable to such indemnified party under
         this Section 4 for any legal or other expenses, subsequently incurred
         by such indemnified party in connection with the defense thereof,
         unless (i) the indemnified party shall have employed separate counsel
         in accordance with the proviso to the next preceding sentence (it
         being understood, however, that in connection with such action the
         indemnifying party shall not be liable for the expenses of more than
         one separate counsel (in addition to local counsel) in any one action
         or separate but substantially similar actions in the same jurisdiction
         arising out of the same general allegations or circumstances,
         designated by the Representatives in the case of paragraph (a) of this
         Section 4, representing the indemnified parties under such paragraph
         (a) who are parties to such action or actions) or (ii) the
         indemnifying party does not promptly retain counsel reasonably
         satisfactory to the indemnified party or (iii) the indemnifying party
         has authorized the employment of counsel for the indemnified party at
         the expense of the indemnifying party.  After such notice from the
         indemnifying party to such indemnified party, the indemnifying party
         will not be liable for the costs and expenses of any settlement of
         such action effected by such indemnified party without the consent of
         the indemnifying party. No indemnifying party shall, without the prior
         written consent of the indemnified parties (which consent shall not be
         unreasonably withheld), settle or compromise or consent to the entry
         of any judgment with respect to any litigation, or any investigation
         or proceeding by any governmental agency or body, commenced or
         threatened, or any claim whatsoever in respect of which
         indemnification or contribution could be sought under this Section 4
         hereof (whether or not the indemnified parties are actual or potential
         parties thereto), unless such settlement, compromise or consent (i)
         includes an unconditional release of each indemnified party from all
         liability arising out of such litigation,



                                      -19-
                                        
   21
         investigation, proceeding or claim 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 any indemnified party.

                 (d)      If at any time an indemnified party shall have
         requested an indemnifying party to reimburse the indemnified party for
         fees and expenses of counsel, such indemnifying party agrees that it
         shall be liable for any settlement of the nature contemplated by
         Section 4(a)(ii) effected without its written consent if (i) such
         settlement is entered into more than 45 days after receipt by such
         indemnifying party of the aforesaid request, (ii) such indemnifying
         party shall have received notice of the terms of such settlement at
         least 30 days prior to such settlement being entered into and (iii)
         such indemnifying party shall not have reimbursed such indemnified
         party in accordance with such request prior to the date of such
         settlement.  Notwithstanding the immediately preceding sentence, if at
         any time an indemnified party shall have requested in good faith an
         indemnifying party to reimburse the indemnified party for specified
         fees and expenses of counsel (the "Requested Expenses"), an
         indemnifying party shall not be liable for any settlement of the
         nature contemplated by Section 4(a)(ii) that is effected without its
         consent (after satisfaction of each of the conditions set forth in the
         immediately preceding sentence) if, prior to the date of such
         settlement, such indemnifying party determines in good faith that the
         Requested Expenses are not reasonable, reimburses such indemnified
         party in accordance with such request for the portion of the Requested
         Expenses it considers to be reasonable and provides written notice to
         the indemnified party substantiating the fact that the unpaid balance
         of the Requested Expenses is unreasonable.

                 (e)      If the indemnification provided for in this Section 4
         is applicable by its terms but is for any reason  unavailable to or
         insufficient to hold harmless an indemnified party in respect of any
         losses, liabilities, claims, damages or expenses referred to therein,
         then each indemnifying party shall contribute to the aggregate amount
         of such losses, liabilities, claims, damages and expenses incurred by
         such indemnified party, as incurred, in such proportion as is
         appropriate to reflect the relative fault of the Company on the one
         hand, the Holders on another hand and the Initial Purchasers on
         another hand with respect to the statements or omissions which
         resulted in such losses, liabilities, claims, damages or expenses, as
         well as any other relevant equitable considerations.

                 The relative fault of the Company on the one hand, the Holders
on another hand, and the Initial Purchasers on another hand shall be determined
by reference to, among other things, whether any such untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a
material fact relates to information supplied by the Company, the Holders or
the Initial Purchasers and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

                 The Company, the Holders and the Initial Purchasers agree that
it would not be just and equitable if contribution pursuant to this Section 4
were determined by pro rata allocation (even if the Initial Purchasers were
treated as one entity for such purpose) or by any other method of allocation
which does not take account of the equitable considerations referred to above
in this




                                      -20-
   22
Section 4. The aggregate amount of losses, liabilities, claims, damages and
expenses incurred by an indemnified party and referred to above in this Section
4 shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.

                 Notwithstanding the provisions of this Section 4, no Initial
Purchaser shall be required to contribute any amount in excess of the amount by
which the total price at which the Securities sold by it were offered exceeds
the amount of any damages which such Initial Purchaser 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 1933 Act) shall be entitled to contribution
from any person who was not guilty of such fraudulent misrepresentation.

                 For purposes of this Section 4, each person, if any, who
controls an Initial Purchaser or Holder within the meaning of Section 15 of the
1933 Act or Section 20 of the 1934 Act shall have the same rights to
contribution as such Initial Purchaser or Holder, and each director of the
Company, and each person, if any, who controls the Company within the meaning
of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same
rights to contribution as the Company.  The Initial Purchasers' respective
obligations to contribute pursuant to this Section 4 are several in proportion
to the principal amount of Securities set forth opposite their respective names
in Schedule A to the Purchase Agreement and not joint.

                 5.               Miscellaneous.

                 5.1              Rule 144 and Rule 144A.  For so long as the
Company is subject to the reporting requirements of Section 13 or 15 of the
1934 Act, the Company covenants that they will file the reports required to be
filed by it under the 1933 Act and Section 13(a) or 15(d) of the 1934 Act and
the rules and regulations adopted by the SEC thereunder.  If the Company ceases
to be so required to file such reports, the Company covenants that it will upon
the request of any Holder of Registrable Securities (a) make publicly available
such information as is necessary to permit sales pursuant to Rule 144 under the
1933 Act, (b) deliver such information to a prospective purchaser as is
necessary to permit sales pursuant to Rule 144A under the 1933 Act and it will
take such further action as any Holder of Registrable Securities may reasonably
request and (c) take such further action that is reasonable in the
circumstances, in each case, to the extent required from time to time to enable
such Holder to sell its Registrable Securities without registration under the
1933 Act within the limitation of the exemptions provided by (i) Rule 144 under
the 1933 Act, as such Rule may be amended from time to time, (ii) Rule 144A
under the 1933 Act, as such Rule may be amended from time to time or (iii) any
similar rules or regulations hereafter adopted by the SEC.  Upon the request




                                      -21-
   23
of any Holder of Registrable Securities, the Company will deliver to such
Holder a written statement as to whether it has complied with such
requirements.

                 5.2              No Inconsistent Agreements. The Company has
not entered into and will not after the date of this Agreement enter into any
agreement which is inconsistent with the rights granted to the Holders of
Registrable Securities in this Agreement or otherwise conflicts with the
provisions hereof.  The rights granted to the Holders hereunder do not in any
way conflict with the rights granted to the holders of the Company's other
issued and outstanding securities under any such agreements.

                 5.3              Amendments and Waivers.  The provisions of
this Agreement, including the provisions of this sentence, may not be amended,
modified or supplemented, and waivers or consents to departures from the
provisions hereof may not be given unless the Company has obtained the written
consent of Holders of at least a majority in aggregate principal amount of the
outstanding Registrable Securities affected by such amendment, modification,
supplement, waiver or departure.  Notwithstanding anything in this Agreement to
the contrary, this Agreement may be amended, modified or supplemented, and
waivers and consents to departures from the provisions hereof may be given, by
written agreement signed by the Company and Merrill Lynch to the extent that
any such amendment, modification, supplement, waiver or consent is, in their
reasonable judgment, necessary or appropriate to comply with applicable law
(including any interpretation of the staff of the SEC) or any change therein.

                 5.4              Notices.  All notices and other
communications provided for or permitted hereunder shall be made in writing by
hand delivery, registered first-class mail, telex, telecopier, or any courier
guaranteeing overnight delivery (a) if to a Holder, at the most current address
given by such Holder to the Company by means of a notice given in accordance
with the provisions of this Section 5.4, which address initially is the address
set forth in the Purchase Agreement with respect to the Initial Purchasers and
(b) if to the Company, initially at the Company's address set forth in the
Purchase Agreement, and thereafter at such other address of which notice is
given in accordance with the provisions of this Section 5.4.

                 All such notices and communications shall be deemed to have
been duly given: at the time delivered by hand, if personally delivered; four
business days after being deposited in the mail, postage prepaid, if mailed;
when answered back, if telexed; when receipt is acknowledged, if telecopied;
and on the next business day if timely delivered to an air courier guaranteeing
overnight delivery.

                 Copies of all such notices, demands, or other communications
shall be concurrently delivered by the person giving the same to the Trustee
under the Indenture, at the address specified in such Indenture.

                 5.5              Successor and Assigns.  This Agreement shall
inure to the benefit of and be binding upon the successors, assigns and
transferees of each of the parties, including, without




                                      -22-
   24
limitation and without the need for an express assignment, subsequent Holders;
provided that nothing herein shall be deemed to permit any assignment, transfer
or other disposition of Registrable Securities in violation of the terms of the
Purchase Agreement and provided, further, that Holders of Registrable
Securities may not assign their rights under this Agreement except in
connection with the permitted transfer of Registrable Securities and then only
insofar as relates to such Registrable Securities.  If any transferee of any
Holder shall acquire Registrable Securities, in any manner, whether by
operation of law or otherwise, such Registrable Securities shall be held
subject to all of the terms of this Agreement, and by taking and holding such
Registrable Securities such person shall be conclusively deemed to have agreed
to be bound by and to perform all of the terms and provisions of this
Agreement, including the restrictions on resale set forth in this Agreement
and, if applicable, the Purchase Agreement, and such person shall be entitled
to receive the benefits hereof.

                 5.6              Third Party Beneficiaries.  The Initial
Purchasers (even if the Initial Purchasers are not Holders of Registrable
Securities) shall be third party beneficiaries to the agreements made hereunder
between the Company, on the one hand, and the Holders, on the other hand, and
shall have the right to enforce such agreements directly to the extent they
deem such enforcement necessary or advisable to protect their rights or the
rights of Holders hereunder.  Each Holder of Registrable Securities shall be a
third party beneficiary to the agreements made hereunder between the Company,
on the one hand, and the Initial Purchasers, on the other hand, and shall have
the right to enforce such agreements directly to the extent it deems such
enforcement necessary or advisable to protect its rights hereunder.

                 5.7              Counterparts.  This Agreement may be executed
in any number of counterparts and by the parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.

                 5.8              Headings.  The headings in this Agreement are
for convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

                 5.9              GOVERNING LAW.  THIS AGREEMENT SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK
WITHOUT REGARD TO THE PRINCIPLES OF CONFLICT OF LAWS THEREOF.

                 5.10             Severability.  In the event that any one or
more of the provisions contained herein, or the application thereof in any
circumstances, is held invalid, illegal or unenforceable, the validity,
legality and enforceability of any such provision in every other respect and of
the remaining provisions contained herein shall not be affected or impaired
thereby.

Ladies and Gentlemen:

         We have acted as counsel for National-Oilwell, Inc., a Delaware
corporation (the "Company"), in connection with the sale by the Company to the
Initial Purchasers (as defined below) of $150,000,000 aggregate principal
amount of 6 7/8 % Senior Notes due 2005 (the "Securities") of the Company
pursuant to the Purchase Agreement dated June 23, 1998 (the "Purchase
Agreement") among the Company, and Merrill Lynch & Co., Merrill Lynch, Pierce,
Fenner & Smith Incorporated, Chase Securities Inc. and Morgan Stanley & Co.
Incorporated (collectively, the "Initial Purchasers") and the filing by the
Company of an Exchange Offer Registration Statement (the "Registration
Statement") in connection with an Exchange Offer to be effected pursuant to the
Registration Rights Agreement (the "Registration Rights Agreement"), dated
June 26, 1998, among the Company, and the Initial Purchasers.  This opinion is
furnished to you pursuant to Section 3(f)(B) of the Registration Rights
Agreement.  Unless otherwise defined herein, capitalized terms used in this
opinion that are defined in the Registration Rights Agreement are used herein
as so defined.

         We have examined such documents, records and matters of law as we have
deemed necessary for purposes of this opinion.  In rendering this opinion, as
to all matters of fact relevant to this opinion, we have relied upon the
representations and warranties of the Company set forth in the Purchase
Agreement and the statements set forth in certificates of public officials and
officers of the Company, without making any independent investigation or
inquiry with respect to the completeness or accuracy of such representations,
warranties or statements.

         Based on and subject to the foregoing, we are of the opinion that the
Exchange Offer Registration Statement and the Prospectus (other than the
financial statements, notes or schedules thereto and other financial data and
supplemental schedules included or incorporated by reference




                                      -25-
   27
therein or omitted therefrom, any reserve data included therein and the Form
T-1, as to which such counsel need express no opinion), comply as to form in
all material respects with the requirements of the 1933 Act and the applicable
rules and regulations promulgated under the 1933 Act.

         In addition to the foregoing opinion, we have participated in the
preparation of the Exchange Offer Registration Statement and Prospectus
included therein and, although we are not passing upon, and do not assume
responsibility for the accuracy, completeness or fairness of, any portion of
the Exchange Offer Registration Statement and such Prospectus (relied to a
large extent as to factual matters upon certificates of officers and directors
of the Company), nothing has come to our attention that causes us to believe
that, at the date it became effective, the Exchange Offer Registration
Statement (other than the financial statements and schedules and the notes
thereto and other financial data included therein, the reserve data included
therein and the Form T-1, as to which we make no statement) 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 such Prospectus (other than the financial statements and schedules and the
notes thereto and other financial data included therein, as to which we make no
statement) as of the date hereof includes an untrue statement of a material
fact or omits to state a material fact necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading.

         The foregoing opinion and comment are is limited in all respects to
federal laws of the United States, the Delaware General Corporation Law and New
York law.  The foregoing opinion and comment are rendered only with respect to
laws, rules, and regulations which are presently in effect and applicable court
rulings and orders which have been published and are generally available and
which are normally applicable to transactions such as the exchange of the
Registrable Securities for the Exchange Securities as described in the Exchange
Offer Registration Statement.  The foregoing opinion and comment are given as
of the date hereof, and we undertake no duty to advise you as to any changes of
law or fact which come to our attention after the date hereof.  This letter is
strictly limited to the opinions expressly set forth herein and is not to be
read as applying by implication or otherwise to any other matter in connection
with the Purchase Agreement or the Registration Rights Agreement other than the
sale by Participating Broker- Dealers of the Securities as described in the
Registration Rights Agreement.

         This opinion is being furnished to you solely for your benefit in
connection with the transactions contemplated by the Registration Rights
Agreement, and may not be used for any other purpose or relied upon by any
person other than you.  Except with our prior written consent, the opinions
herein expressed are not to be used, circulated, quoted or otherwise referred
to in connection with any transactions other than those contemplated by the
Registration Rights Agreement by or to any other person.

                               Very truly yours,




                                      -26-
