                                                                               4

not satisfy the Company's periodic reporting requirements as set forth under the

225 days of the date of the original issuance of the Securities.

            (b) Upon the effectiveness of the Exchange Offer Registration
Statement, the Company shall promptly commence the Registered Exchange Offer, it
being the objective of such Registered Exchange Offer to enable each Holder
electing to exchange Securities for New Securities (assuming that such Holder is
not an Affiliate of the Company, acquires the New Securities in the ordinary
course of such Holder's business, has no arrangements with any person to
participate in the distribution of the New Securities and is not prohibited by
any law or policy of the Commission from participating in the Registered
Exchange Offer) to trade such New Securities from and after their receipt
without any limitations or restrictions under the Act and without material
restrictions under the securities laws of a substantial proportion of the
several states of the United States.

            (c) In connection with the Registered Exchange Offer, the Company
shall:

            (i) mail to each Holder a copy of the Prospectus forming part of the
      Exchange Offer Registration Statement, together with an appropriate letter
      of transmittal and related documents;

            (ii) keep the Registered Exchange Offer open for not less than 20
      Business Days and unless separately agreed in writing, not more than 30
      Business Days after the date notice thereof is mailed to the Holders (or,
      in each case, longer if required by applicable law);

            (iii) use its best efforts to keep the Exchange Offer Registration
      Statement continuously effective, supplemented and amended as required,
      under the Act to ensure that it is available for sales of New Securities
      by Participating Broker-Dealers during the Exchange Offer Registration
      Period;

            (iv) utilize the services of a depositary for the Registered
      Exchange Offer with an address in the Borough of Manhattan in New York
      City, which may be the Trustee or an Affiliate of it;

            (v) permit Holders to withdraw tendered Securities at any time prior
      to the close of business, New York time, on the last Business Day on which
      the Registered Exchange Offer is open;

            (vi) prior to effectiveness of the Exchange Offer Registration
      Statement, if requested or required by the Commission, provide a
      supplemental letter to the Commission (A) stating that the Company is
      conducting the Registered Exchange Offer in reliance on the position of
      the Commission in Exxon Capital Holdings Corporation (pub. avail. May 13,
      1988) and Morgan Stanley and Co., Inc. (pub. avail. June 5, 1991); and (B)
      including a representation that the Company has not entered into any
      arrangement or understanding with any person to distribute the New
      Securities to be received in the Registered Exchange Offer and that, to
      the best of the Company's information and belief, each Holder
      participating in the Registered Exchange Offer is acquiring the New
      Securities in the ordinary course of business and has no arrangement or
      understanding with any person to participate in the distribution of the
      New Securities; and

<PAGE>
                                                                               5

            (vii) comply in all respects with all applicable laws.

            (d) As soon as practicable after the close of the Registered
Exchange Offer, the Company shall:

            (i) accept for exchange all Securities validly tendered and not
      withdrawn pursuant to the Registered Exchange Offer;

            (ii) deliver to the Trustee for cancellation in accordance with
      Section 4(s) all Securities so accepted for exchange; and

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

            (e) Each Holder hereby acknowledges and agrees that any such Holder
using the Registered Exchange Offer to participate in a distribution of the New
Securities (x) could not under Commission policy as in effect on the date of
this Agreement rely on the position of the Commission in Morgan Stanley and Co.,
Inc. (pub. avail. June 5, 1991) and Exxon Capital Holdings Corporation (pub.
avail. May 13, 1988), as interpreted in the Commission's letter to Shearman &
Sterling dated July 2, 1993 and similar no-action letters; and (y) must comply
with the registration and prospectus delivery requirement of the Act in
connection with any secondary resale transaction which must be covered by an
effective registration statement containing the selling security holder
information required by Item 507 or 508, as applicable, of Regulation S-K under
the Act if the resales are of New Securities obtained by such Holder in exchange
for Securities acquired by such Holder directly from the Company or one of its
Affiliates. Accordingly, each Holder participating in the Registered Exchange
Offer shall be required to represent to the Company that, at the time of the
consummation of the Registered Exchange Offer:

            (i) any New Securities received by such Holder will be acquired in
      the ordinary course of business;

            (ii) such Holder will have no arrangement or understanding with any
      person to participate in the distribution of the Securities or the New
      Securities within the meaning of the Act;

            (iii) such Holder is not an Affiliate of the Company;

            (iv) if such Holder is not a broker-dealer, that it is not engaged
      in, and does not intend to engage in, the distribution of the New
      Securities; and

            (v) if such Holder is a broker-dealer, that it will receive New
      Securities for its own account in exchange for Securities that were
      acquired as a result of market-making activities or other trading
      activities and that it will be required to acknowledge that it will
      deliver a Prospectus in connection with any resale of such New Securities.

            (f) If, prior to the consummation of the Registered Exchange Offer,
any Initial Purchaser determines that it is not eligible to participate in the
Registered Exchange Offer with respect to the exchange of Securities
constituting any portion of an unsold allotment, at the request of such Initial
Purchaser, the Company shall issue and deliver to such Initial Purchaser or

<PAGE>
                                                                               6

the person purchasing New Securities registered under a Shelf Registration
Statement as contemplated by Section 3 hereof from such Initial Purchaser, in
exchange for such Securities, a like principal amount of New Securities. The
Company shall use its reasonable best efforts to cause the CUSIP Service Bureau
to issue the same CUSIP number for such New Securities as for New Securities
issued pursuant to the Registered Exchange Offer.

            3. Shelf Registration. (a) If (i) due to any change in law or
applicable interpretations thereof by the Commission's staff, the Company
determines upon advice of its outside counsel that it is not permitted to effect
the Registered Exchange Offer as contemplated by Section 2 hereof; (ii) for any
other reason the Registered Exchange Offer is not consummated within 270 days of
the date of original issuance of the Securities; (iii) any Initial Purchaser so
requests with respect to Securities that are not eligible to be exchanged for
New Securities in the Registered Exchange Offer and that are held by it
following consummation of the Registered Exchange Offer; (iv) any Holder (other
than an Initial Purchaser) is not eligible to participate in the Registered
Exchange Offer or does not receive freely tradeable New Securities in the
Registered Exchange Offer other than by reason of such Holder being an Affiliate
of the Company; or (v) in the case of any Initial Purchaser that participates in
the Registered Exchange Offer or acquires New Securities pursuant to Section
2(f) hereof, such Initial Purchaser does not receive freely tradeable New
Securities in exchange for Securities constituting any portion of an unsold
allotment (it being understood that (x) the requirement that an Initial
Purchaser deliver a Prospectus containing the information required by Item 507
or 508 of Regulation S-K under the Act in connection with sales of New
Securities acquired in exchange for such Securities shall result in such New
Securities being not "freely tradeable"; and (y) the requirement that an
Participating Broker-Dealer deliver an Exchange Offer Prospectus in connection
with sales of New Securities acquired in the Registered Exchange Offer in
exchange for Securities acquired as a result of market-making activities or
other trading activities shall not result in such New Securities being not
"freely tradeable"), the Company shall effect a Shelf Registration Statement in
accordance with subsection (b) below.

            (b) (i) The Company shall as promptly as practicable (but in no
event more than 30-days after so required or requested pursuant to this Section
3), file with the Commission and thereafter shall use its reasonable best
efforts to cause to be declared effective under the Act a Shelf Registration
Statement relating to the offer and sale of the Securities or the New
Securities, as applicable, by the Holders thereof from time to time in
accordance with the methods of distribution elected by such Holders and set
forth in such Shelf Registration Statement; provided, however, that no Holder
(other than an Initial Purchaser) shall be entitled to have the Securities held
by it covered by such Shelf Registration Statement unless such Holder agrees in
writing to be bound by all of the provisions of this Agreement applicable to
such Holder; and provided further, that with respect to New Securities received
by an Initial Purchaser in exchange for Securities constituting any portion of
an unsold allotment, the Company may, if permitted by current interpretations by
the Commission's staff, file a post-effective amendment to the Exchange Offer
Registration Statement containing the information required by Item 507 or 508 of
Regulation S-K, as applicable, in satisfaction of its obligations under this
subsection with respect thereto, and any such Exchange Offer Registration
Statement, as so amended, shall be referred to herein as, and governed by the
provisions herein applicable to, a Shelf Registration Statement. The Company
may, in lieu of such a filing and within the time period provided for such a
filing, confidentially submit the Shelf Registration Statement to the
Commission; provided that the Company shall promptly provide to the Trustee a
copy of the cover letter accompanying such submission; and provided, further,
that a confidential submission to the Commission shall not satisfy the Company's
periodic reporting requirements as set forth under the Indenture.

                                                                               7

            (ii) The Company shall use its reasonable best efforts to keep the
Shelf Registration Statement continuously effective, supplemented and amended as
required by the Act, in order to permit the Prospectus forming part thereof to
be usable by Holders for a period of two years from the date the Shelf
Registration Statement is declared effective by the Commission or such shorter
period that will terminate when all the Securities or New Securities, as
applicable, covered by the Shelf Registration Statement have been sold pursuant
to the Shelf Registration Statement (in any such case, such period being called
the "Shelf Registration Period"). The Company shall be deemed not to have used
its reasonable best efforts to keep the Shelf Registration Statement effective
during the requisite period if it voluntarily takes any action that would result
in Holders of Securities covered thereby not being able to offer and sell such
Securities during that period, unless (A) such action is required by applicable
law; or (B) such action is taken by the Company in good faith and for valid
business reasons (not including avoidance of the Company's obligations
hereunder), including the acquisition or divestiture of assets, so long as the
Company promptly thereafter complies with the requirements of Section 4(k)
hereof, if applicable.

            4. Additional Registration Procedures. In connection with any Shelf
Registration Statement and, to the extent applicable, any Exchange Offer
Registration Statement, the following provisions shall apply.

            (a) The Company shall:

            (i) furnish to you, not less than two Business Days prior to the
      filing thereof with the Commission, a copy of any Exchange Offer
      Registration Statement and any Shelf Registration Statement, and each
      amendment thereof and each amendment or supplement, if any, to the
      Prospectus included therein (including all documents incorporated by
      reference therein (unless otherwise publicly available) after the initial
      filing) and shall use its reasonable best efforts to reflect in each such
      document, when so filed with the Commission, such comments as you
      reasonably propose;

            (ii) include the information set forth in Annex A hereto on the
      facing page of the Exchange Offer Registration Statement, in Annex B
      hereto in the forepart of the Exchange Offer Registration Statement in a

      the underwriting or plan of distribution section of the Prospectus
      contained in the Exchange Offer Registration Statement, and in Annex D
      hereto in the letter of transmittal delivered pursuant to the Registered
      Exchange Offer;

            (iii) if requested by an Initial Purchaser, include the information
      required by Item 507 or 508 of Regulation S-K, as applicable, in the
      Prospectus contained in the Exchange Offer Registration Statement; and

            (iv) in the case of a Shelf Registration Statement, include the
      names of the Holders that propose to sell Securities pursuant to the Shelf
      Registration Statement as selling security holders.

            (b) The Company shall ensure that:

            (i) any Registration Statement and any amendment thereto and any
      Prospectus forming part thereof and any amendment or supplement thereto
      complies in all material respects with the Act and the rules and
      regulations thereunder;

<PAGE>
                                                                               8

            (ii) any 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; provided,
      however, that the Company will not be liable for written information
      furnished to the Company by or on behalf of any Holder or Initial
      Purchaser specifically for inclusion therein; and

            (iii) any Prospectus forming part of any Registration Statement, and
      any amendment or supplement to such Prospectus, does not include an 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
      under which they were made, not misleading; provided, however, that the
      Company will not be liable for written information furnished to the
      Company by or on behalf of any Holder or Initial Purchaser specifically
      for inclusion therein.

            (c) The Company shall advise you, the Holders of Securities covered
by any Shelf Registration Statement and any Participating Broker-Dealer under
any Exchange Offer Registration Statement that has provided in writing to the
Company a telephone or facsimile number and address for notices, and, if
requested by you or any such Holder or Participating Broker-Dealer, shall
confirm such advice in writing (which notice pursuant to clauses (ii) through
(v) hereof shall be accompanied by an instruction to suspend the use of the
Prospectus until the Company shall have remedied the basis for such suspension):

            (i) when a Registration Statement and any amendment thereto has been
      filed with the Commission and when the Registration Statement or any
      post-effective amendment thereto has become effective;

            (ii) of any request by the Commission for any amendment or
      supplement to the Registration Statement or the Prospectus or for
      additional information;

            (iii) of the issuance by the Commission of any stop order suspending
      the effectiveness of the Registration Statement or the initiation of any
      proceedings for that purpose;

            (iv) of the receipt by the Company of any notification with respect
      to the suspension of the qualification of the Securities or New Securities
      included therein for sale in any jurisdiction or the initiation of any
      proceeding for such purpose; and

            (v) of the happening of any event that requires any change in the
      Registration Statement or the Prospectus so that, as of such date, the
      statements therein are not misleading and do not omit to state a material
      fact required to be stated therein or necessary to make the statements
      therein (in the case of the Prospectus, in the light of the circumstances
      under which they were made) not misleading.

            (d) The Company shall use its reasonable best efforts to obtain the
withdrawal of any order suspending the effectiveness of any Registration
Statement or the qualification of the securities therein for sale in any
jurisdiction at the earliest possible time.

            (e) The Company shall furnish to each Holder of Securities covered
by any Shelf Registration Statement, without charge, at least one copy of such
Shelf Registration Statement

<PAGE>
                                                                               9

and any post-effective amendment thereto, including all material incorporated
therein by reference (unless otherwise publicly available), and, if the Holder
so requests in writing, all exhibits (unless otherwise publicly available)
thereto (including exhibits incorporated by reference therein).

            (f) The Company shall, during the Shelf Registration Period, deliver
to each Holder of Securities covered by any Shelf Registration Statement,
without charge, as many copies of the Prospectus (including each preliminary
Prospectus) included in such Shelf Registration Statement and any amendment or
supplement thereto as such Holder may reasonably request. The Company consents,
subject to the provisions of this Agreement, to the use of the Prospectus or any
amendment or supplement thereto by each of the selling Holders of Securities in
connection with the offering and sale of the Securities covered by the
Prospectus, or any amendment or supplement thereto, included in the Shelf
Registration Statement.

            (g) The Company shall furnish to each Participating Broker-Dealer
which so requests, without charge, at least one copy of the Exchange Offer
Registration Statement and any post-effective amendment thereto, including all
material (unless otherwise publicly available) incorporated by reference
therein, and, if the Participating Broker-Dealer so requests in writing, all
exhibits (unless otherwise publicly available) thereto (including exhibits
incorporated by reference therein).

            (h) The Company shall promptly deliver to each Initial Purchaser,
each Participating Broker-Dealer and each other person required to deliver a
Prospectus during the Exchange Offer Registration Period, without charge, as
many copies of the Prospectus included in such Exchange Offer Registration
Statement and any amendment or supplement thereto as any such person may
reasonably request. The Company consents, subject to the provisions of this
Agreement, to the use of the Prospectus or any amendment or supplement thereto
by any Initial Purchaser, any Participating Broker-Dealer and any such other
person that may be required to deliver a Prospectus following the Registered
Exchange Offer in connection with the offering and sale of the New Securities
covered by the Prospectus, or any amendment or supplement thereto, included in
the Exchange Offer Registration Statement.

            (i) Prior to the Registered Exchange Offer or any other offering of
Securities pursuant to any Registration Statement, the Company shall arrange, if
necessary, for the qualification of the Securities or the New Securities for
offer and sale in Luxembourg and under the securities or "blue sky" laws of such
State of the United States as any Holder shall reasonably request in writing and
will maintain such qualification in effect so long as required; provided,
however, that in no event shall the Company be obligated (x) to qualify to do
business in any jurisdiction where it is not then so qualified or (y) to take
any action that would subject it to service of process in suits, other than
those arising out of the Initial Placement, the Registered Exchange Offer or any
offering pursuant to a Shelf Registration Statement, in any such jurisdiction
where it is not then so subject.

            (j) The Company shall cooperate with the Holders of Securities to
facilitate the timely preparation and delivery, within a reasonable period of
time prior to the issuance or sale of the Securities or New Securities pursuant
to any Registration Statement, of certificates representing New Securities or
Securities to be issued or sold pursuant to any Registration Statement free of
any restrictive legends and in such denominations and registered in such names
as Holders may request.

            (k) Upon the occurrence of any event contemplated by subsections
(c)(ii) through (v) above, during the period for which the Company is required
to maintain an effective Registration Statement, the Company shall promptly
prepare a post-effective amendment to the applicable Registration Statement or
an amendment or supplement to the related Prospectus or file any other required
document so that, as thereafter delivered to Holders of the Securities or New
Securities included therein, the Prospectus will not 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. In such circumstances, if the Company notifies the Initial
Purchasers, the Holders of the Securities and any known participating
Broker-Dealer in accordance with paragraphs (c) (i) through (v) of Section (4)
above to suspend the use of the Prospectus until the requisite changes to the
Prospectus have been made, then the Initial Purchasers, the Holders of the
Securities and any such participating Broker-Dealers shall suspend use of such
Prospectus and the period of effectiveness of the Exchange Offer Registration
Statement provided for in Section 2 and the Shelf Registration Statement
provided for in Section 3(b) shall each be extended by the number of days from
and including the date of the giving of a notice of suspension pursuant to
Section 4(c) to and including the date when the Initial Purchasers, the Holders
of the Securities and any known Broker-Dealer shall have received such amended
or supplemented Prospectus pursuant to this Section 4(k).

            (l) Not later than the effective date of any Registration Statement,
the Company shall provide a CUSIP number for the Securities or the New
Securities, as the case may be, registered under such Registration Statement and
provide the Trustee with printed certificates for such Securities or New
Securities, in a form eligible for deposit with The Depository Trust Company.

            (m) The Company shall comply with all applicable rules and
regulations of the Commission, and shall make generally available to its
security holders, or otherwise provide in accordance with Section 11(a) of the
Act, as soon as practicable after the effective date of the applicable
Registration Statement an earnings statement satisfying the provisions of
Section 11(a) of the Act.

            (n) The Company shall cause the Indenture to be qualified under the
Trust Indenture Act in a timely manner.

            (o) The Company may require each Holder of Securities to be sold
pursuant to any Shelf Registration Statement to furnish to the Company such
information regarding the Holder and the distribution of such Securities as the
Company may from time to time reasonably require for inclusion in such Shelf
Registration Statement. The Company may exclude from such Shelf Registration
Statement the Securities of any Holder that unreasonably fails to furnish such
information within a reasonable time after receiving such request.

            (p) In the case of any Shelf Registration Statement, the Company
shall enter into such agreements (including if requested an underwriting
agreement in customary form) and take all other necessary actions in order to
expedite or facilitate the registration or the disposition of the Securities
pursuant to any such Shelf Registration Statement, and in connection therewith,
if an underwriting agreement is entered into, cause the same to contain
indemnification provisions and procedures no less favorable than those set forth
in Section 6 (or such other provisions and procedures acceptable to the Majority
Holders and the Managing Underwriters, if any) with respect to all parties to be
indemnified pursuant to Section 6.

            (q) In the case of any Shelf Registration Statement, the Company
shall:

            (i) make reasonably available for inspection by the Holders of
      Securities to be registered thereunder, any underwriter participating in
      any disposition pursuant to such Shelf Registration Statement, and any
      attorney, accountant or other agent retained by the Holders or any such
      underwriter all relevant financial and other records, pertinent corporate
      documents and properties of the Company and its subsidiaries as shall be
      reasonably necessary to enable such person to conduct a reasonable
      investigation within the meaning of Section 11 of the Act; provided,
      however, that any information that is designated in writing by the
      Company, in good faith, as confidential at the time of delivery of such
      information shall be kept confidential by the Holders or any such
      underwriter, attorney, accountant or agent, unless such disclosure is made
      in connection with a court proceeding or required by law, or such
      information becomes available to the public generally or through a third
      party without an accompanying obligation of confidentiality; provided
      further, however, that the foregoing inspection and information gathering
      shall be coordinated on behalf of the Holders by the Representatives and
      on behalf of other parties, by one counsel designated by and on behalf of
      such other parties as described in Section 5 hereof;

            (ii) cause the Company's officers, directors and employees to supply
      all relevant information reasonably requested by the Holders or any such
      underwriter, attorney, accountant or agent in connection with any such
      Shelf Registration Statement as is customary for similar due diligence
      examinations; provided, however, that any information that is designated
      in writing by the Company, in good faith, as confidential at the time of
      delivery of such information shall be kept confidential by the Holders or
      any such underwriter, attorney, accountant or agent, unless such
      disclosure is made in connection with a court proceeding or required by
      law, or such information becomes available to the public generally or
      through a third party without an accompanying obligation of
      confidentiality; provided further, however, that the foregoing inspection
      and information gathering shall be coordinated on behalf of the Holders by
      the Representatives and on behalf of other parties, by one counsel
      designated by and on behalf of such other parties as described in Section
      5 hereof;

            (iii) make such representations and warranties to the Holders of
      Securities registered thereunder and the underwriters, if any, in form,
      substance and scope as are customarily made by issuers to underwriters in
      primary underwritten offerings and covering matters including, but not
      limited to, those set forth in the Purchase Agreement;

            (iv) obtain opinions of counsel to the Company and updates thereof
      (which counsel and opinions (in form, scope and substance) shall be
      reasonably satisfactory to the Managing Underwriters, if any) addressed to
      each selling Holder and the Managing Underwriters, if any, on behalf of
      the underwriters, covering such matters as are customarily covered in
      opinions requested in underwritten offerings and such other matters as may
      be reasonably requested by such Holders and Managing Underwriters;

            (v) obtain "cold comfort" letters and updates thereof from the
      independent certified public accountants of the Company (and, if
      necessary, any other independent certified public accountants of any
      subsidiary of the Company or of any business acquired by the Company for
      which financial statements and financial data are, or are required to be,
      included in the Shelf Registration Statement), addressed to each selling
      Holder of Securities registered thereunder and the underwriters, if any,
      in customary form and

<PAGE>
                                                                              12

      covering matters of the type customarily covered in "cold comfort" letters
      in connection with primary underwritten offerings; and

            (vi) deliver such documents and certificates as may be reasonably
      requested by the Majority Holders and the Managing Underwriters, if any,
      including those to evidence compliance with Section 4(k) and with any
      customary conditions contained in the underwriting agreement or other
      agreement entered into by the Company.

The actions set forth in clauses (iii), (iv), (v) and (vi) of this Section shall
be performed at (A) the effectiveness of such Shelf Registration Statement and
each post-effective amendment thereto; and (B) each closing under any
underwriting or similar agreement as and to the extent required thereunder.

            (r) In the case of any Exchange Offer Registration Statement, the
Company shall, to the extent requested by the Initial Purchasers:

            (i) make reasonably available for inspection by such Initial
      Purchaser, and any attorney, accountant or other agent retained by such
      Initial Purchaser, all relevant financial and other records, pertinent
      corporate documents and properties of the Company and its subsidiaries as
      shall be reasonably necessary to enable such person to conduct a
      reasonable investigation within the meaning of Section 11 of the Act;
      provided, however, that any information that is designated in writing by
      the Company, in good faith, as confidential at the time of delivery of
      such information shall be kept confidential by the Holders or any such
      underwriter, attorney, accountant or agent, unless such disclosure is made
      in connection with a court proceeding or required by law, or such
      information becomes available to the public generally or through a third
      party without an accompanying obligation of confidentiality; provided
      further, however, that the foregoing inspection and information gathering
      shall be coordinated on behalf of the Holders by the Representatives and
      on behalf of other parties, by one counsel designated by and on behalf of
      such other parties as described in Section 5 hereof;

            (ii) cause the Company's officers, directors and employees to supply
      all relevant information reasonably requested by such Initial Purchaser or
      any such attorney, accountant or agent in connection with any such
      Exchange Offer Registration Statement as is customary for similar due
      diligence examinations; provided, however, that any information that is
      designated in writing by the Company, in good faith, as confidential at
      the time of delivery of such information shall be kept confidential by
      such Initial Purchaser or any such attorney, accountant or agent, unless
      such disclosure is made in connection with a court proceeding or required
      by law, or such information becomes available to the public generally or
      through a third party without an accompanying obligation of
      confidentiality; provided further, however, that the foregoing inspection
      and information gathering shall be coordinated on behalf of the Holders by
      the Representatives and on behalf of other parties, by one counsel
      designated by and on behalf of such other parties as described in Section
      5 hereof;

            (iii) make such representations and warranties to such Initial
      Purchaser, in form, substance and scope as are customarily made by issuers
      to underwriters in primary underwritten offerings and covering matters
      including, but not limited to, those set forth in the Purchase Agreement;

                                                                              13

            (iv) obtain opinions of counsel to the Company and updates thereof
      (which counsel and opinions (in form, scope and substance) shall be
      reasonably satisfactory to such Initial Purchaser and its counsel,
      addressed to such Initial Purchaser, covering such matters as are
      customarily covered in opinions requested in underwritten offerings and
      such other matters as may be reasonably requested by such Initial
      Purchaser or its counsel;

            (v) obtain "cold comfort" letters and updates thereof from the
      independent certified public accountants of the Company (and, if
      necessary, any other independent certified public accountants of any
      subsidiary of the Company or of any business acquired by the Company for
      which financial statements and financial data are, or are required to be,
      included in the Registration Statement), addressed to such Initial
      Purchaser, in customary form and covering matters of the type customarily
      covered in "cold comfort" letters in connection with primary underwritten
      offerings, or if requested by such Initial Purchaser or its counsel in
      lieu of a "cold comfort" letter, an agreed-upon procedures letter under
      Statement on Auditing Standards No. 35, covering matters requested by such
      Initial Purchaser or its counsel; and

            (vi) deliver such documents and certificates as may be reasonably
      requested by such Initial Purchaser or its counsel, including those to
      evidence compliance with Section 4(k) and with conditions customarily
      contained in underwriting agreements.

The foregoing actions set forth in clauses (iii), (iv), (v), and (vi) of this
Section shall be performed at the close of the Registered Exchange Offer and the
effective date of any post-effective amendment to the Exchange Offer
Registration Statement.

            (s) If a Registered Exchange Offer is to be consummated, upon
delivery of the Securities by Holders to the Company (or to such other person as
directed by the Company) in exchange for the New Securities, the Company shall
mark, or cause to be marked, on the Securities so exchanged that such Securities
are being canceled in exchange for the New Securities. In no event shall the
Securities be marked as paid or otherwise satisfied.

            (t) The Company will use its reasonable best efforts, if the
Securities have been rated prior to the initial sale of such Securities, to
confirm such ratings will apply to the Securities or the New Securities, as the
case may be, covered by a Registration Statement.

            (u) In the event that any Broker-Dealer shall underwrite any
Securities or participate as a member of an underwriting syndicate or selling
group or "assist in the distribution" (within the meaning of the Rules of Fair
Practice and the By-Laws of the National Association of Securities Dealers,
Inc.) thereof, whether as a Holder of such Securities or as an underwriter, a
placement or sales agent or a broker or dealer in respect thereof, or otherwise,
the Company shall assist such Broker-Dealer in complying with the requirements
of such Rules and By-Laws, including, without limitation, by:

            (i) if such Rules or By-Laws shall so require, engaging a "qualified
      independent underwriter" (as defined in such Rule 2720) to participate in
      the preparation of the Registration Statement, to exercise usual standards
      of due diligence with respect thereto and, if any portion of the offering
      contemplated by such Registration Statement is an underwritten offering or
      is made through a placement or sales agent, to recommend the yield of such
      Securities;

<PAGE>
                                                                              14

            (ii) indemnifying any such qualified independent underwriter to the
      extent of the indemnification of underwriters provided in Section 6
      hereof; and

            (iii) providing such information to such Broker-Dealer as may be
      required in order for such Broker-Dealer to comply with the requirements
      of such Rules.

            (v) The Company shall use its best efforts to take all other steps
necessary to effect the registration of the Securities or the New Securities, as
the case may be, covered by a Registration Statement.

            5. Registration Expenses. The Company shall bear all expenses
incurred in connection with the performance of its obligations under Sections 2,
3 and 4 hereof and, in the event of any Shelf Registration Statement, will
reimburse the Holders for the reasonable fees and disbursements of one firm or
counsel designated by the Majority Holders to act as counsel for the Holders in
connection therewith, and, in the case of any Exchange Offer Registration
Statement, will reimburse the Initial Purchasers for the reasonable fees and
disbursements of counsel acting in connection therewith.

            6. Indemnification and Contribution. (a) The Company agrees to
indemnify and hold harmless each Holder of Securities or New Securities, as the
case may be, covered by any Registration Statement (including each Initial
Purchaser and, with respect to any Prospectus delivery as contemplated in
Section 4(h) hereof, each Participating Broker-Dealer), the directors, officers,
employees and agents of each such Holder and each person who controls any such
Holder within the meaning of either the Act or the Exchange Act against any and
all losses, claims, damages or liabilities, joint or several, to which they or
any of them may become subject under the Act, the Exchange Act or other Federal
or state statutory law or regulation, at common law 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 a material fact contained in any Registration Statement as originally filed
or in any amendment thereof, or in any preliminary Prospectus or the Prospectus,
or in any amendment thereof 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 not misleading
and agrees to reimburse each such indemnified party, as incurred, for any legal
or other expenses reasonably incurred by them in connection with investigating
or defending any such loss, claim, damage, liability or action; provided,
however, that (i) the Company will not be liable in any case to the extent that
any such loss, claim, damage or liability arises out of or is based upon any
such untrue statement or alleged untrue statement or omission or alleged
omission made therein in reliance upon and in conformity with written
information furnished to the Company by or on behalf of any such Holder or
Initial Purchaser specifically for inclusion therein and (ii) with respect to
any untrue statement or omission or alleged untrue statement or omission made in
any preliminary Prospectus, the indemnity agreement contained in this subsection
shall not inure to the benefit of any Holder, Initial Purchaser or Participating
Broker-Dealer, as the case may be, from whom the person asserting such losses,
claims, damages or liabilities purchased the Securities or New Securities
concerned if a Prospectus relating to such Securities or New Securities was
required to be delivered by such Holder, Initial Purchaser or Participating
Broker-Dealer under the Act in connection with such purchase and any such loss,
claim, damage or liability of such Holder, Initial Purchaser or Participating
Broker-Dealer results from the fact that there was not sent of given to such
person, at or prior to the written confirmation of the sale of such Securities
or New Securities to such person a copy of the final Prospectus if the Company
had previously furnished copies thereof to such Holder, Initial Purchaser or
Participating Broker-Dealer and such untrue statement or omission or alleged
untrue

<PAGE>
                                                                              15

statement or omission was corrected in the final Prospectus. This indemnity
agreement will be in addition to any liability which the Company may otherwise
have.

            The Company also agrees to indemnify or contribute as provided in
Section 6(d) to Losses of each underwriter of Securities or New Securities, as
the case may be, registered under a Shelf Registration Statement, their
directors, officers, employees or agents and each person who controls such
underwriter on substantially the same basis as that of the indemnification of
the Initial Purchasers and the selling Holders provided in this Section 6(a) and
shall, if requested by any Holder, enter into an underwriting agreement
reflecting such agreement, as provided in Section 4(p) hereof.

            (b) Each Holder of securities covered by a Registration Statement
(including each Initial Purchaser and, with respect to any Prospectus delivery
as contemplated in Section 4(h) hereof, each Participating Broker-Dealer)
severally and not jointly agrees to indemnify and hold harmless the Company,
each of its directors, each of its officers who signs such Registration
Statement and each person who controls the Company within the meaning of either
the Act or the Exchange Act, to the same extent as the foregoing indemnity from
the Company to each such Holder, but only with reference to written information
relating to such Holder furnished to the Company by or on behalf of such Holder
specifically for inclusion in the documents referred to in the foregoing
indemnity. This indemnity agreement will be in addition to any liability which
any such Holder may otherwise have.

            (c) Promptly after receipt by an indemnified party under this
Section 6 of notice of the commencement of any action or proceeding, such
indemnified party will, if a claim in respect thereof is to be made against the
indemnifying party under this Section 6, notify the indemnifying party in
writing of the commencement thereof; but the failure so to notify the
indemnifying party (i) will not relieve it from liability under paragraph (a) or
(b) above unless such failure results in the forfeiture by the indemnifying
party of substantial rights and defenses; and (ii) will not, in any event,
relieve the indemnifying party from any obligations to any indemnified party
other than the indemnification obligation provided in paragraph (a) or (b)
above. The indemnifying party shall be entitled to appoint counsel of the
indemnifying party's choice at the indemnifying party's expense to represent the
indemnified party in any action for which indemnification is sought (in which
case the indemnifying party shall not thereafter be responsible for the fees and
expenses of any separate counsel retained by the indemnified party or parties
except as set forth below); provided, however, that such counsel shall be
reasonably satisfactory to the indemnified party. Notwithstanding the
indemnifying party's election to appoint counsel to represent the indemnified
party in an action, the indemnified party shall have the right to employ
separate counsel (including local counsel), and the indemnifying party shall
bear the reasonable fees, costs and expenses of such separate counsel if (i) the
use of counsel chosen by the indemnifying party to represent the indemnified
party would present such counsel with a conflict of interest; (ii) the actual or
potential defendants in, or targets of, any such action include both the
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be legal defenses available to it
and/or other indemnified parties which are different from or additional to those
available to the indemnifying party; (iii) the indemnifying party shall not have
employed counsel satisfactory to the indemnified party to represent the
indemnified party within a reasonable time after notice of the institution of
such action or proceeding; or (iv) the indemnifying party shall authorize the
indemnified party to employ separate counsel at the expense of the indemnifying
party. An indemnifying party will not, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be

<PAGE>
                                                                              16

sought hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding, and 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) In the event that the indemnity provided in paragraph (a) or (b)
of this Section 6 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, then each applicable indemnifying party shall
have a joint and several obligation to contribute to the aggregate losses,
claims, damages and liabilities (including legal or other expenses reasonably
incurred in connection with investigating or defending same) (collectively
"Losses") to which such indemnified party may be subject in such proportion as
is appropriate to reflect the relative benefits received by such indemnifying
party, on the one hand, and such indemnified party, on the other hand, from the
Initial Placement and the Registration Statement which resulted in such Losses;
provided, however, that in no case shall any Initial Purchaser or any subsequent
Holder of any Security or New Security be responsible, in the aggregate, for any
amount in excess of the purchase discount or commission applicable to such
Security, or in the case of a New Security, applicable to the Security that was
exchangeable into such New Security, as set forth on the cover page of the Final
Memorandum, nor shall any underwriter be responsible for any amount in excess of
the underwriting discount or commission applicable to the securities purchased
by such underwriter under the Registration Statement which resulted in such
Losses. If the allocation provided by the immediately preceding sentence is
unavailable for any reason, the indemnifying party and the indemnified party
shall contribute in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of such indemnifying party, on the
one hand, and such indemnified party, on the other hand, in connection with the
statements or omissions which resulted in such Losses as well as any other
relevant equitable considerations. Benefits received by the Company shall be
deemed to be equal to the sum of (x) the total net proceeds from the Initial
Placement (before deducting expenses) as set forth on the cover page of the
Final Memorandum and (y) the total amount of additional interest which the
Company was not required to pay as a result of registering the securities
covered by the Registration Statement which resulted in such Losses. Benefits
received by the Initial Purchasers shall be deemed to be equal to the total
purchase discounts and commissions as set forth on the cover page of the Final
Memorandum, and benefits received by any other Holders shall be deemed to be
equal to the value of receiving Securities or New Securities, as applicable,
registered under the Act. Benefits received by any underwriter shall be deemed
to be equal to the total underwriting discounts and commissions, as set forth on
the cover page of the Prospectus forming a part of the Registration Statement
which resulted in such Losses. Relative fault shall be determined by reference
to, among other things, whether any alleged untrue statement or omission relates
to information provided by the indemnifying party, on the one hand, or by the
indemnified party, on the other hand, the intent of the parties and their
relative knowledge, access to information and opportunity to correct or prevent
such untrue statement or omission. The parties agree that it would not be just
and equitable if contribution were determined by pro rata allocation (even if
the Holders were treated as one entity for such purpose) or any other method of
allocation which does not take account of the equitable considerations referred
to above. Notwithstanding the provisions of this paragraph (d), 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. For purposes of this Section, each person who
controls a Holder within the meaning of either the Act or the Exchange Act and
each director, officer, employee and agent of such Holder shall have the same
rights to contribution as such Holder, and each person who controls the Company
within the meaning of either the Act or the Exchange Act, each officer of the

director of the Company shall have the same rights to contribution as the
Company, subject in each case to the applicable terms and conditions of this
paragraph (d).

            (e) The provisions of this Section will remain in full force and
effect, regardless of any termination or cancellation of this Agreement or any
investigation made by or on behalf of any Holder or the Company or any of the
directors, officers, employees, agents or controlling persons referred to in
this Section 6 hereof, and will survive the sale by a Holder of Securities or
New Securities covered by a Registration Statement.

            7. Underwritten Registrations. (a) If any of the Securities or New
Securities, as the case may be, covered by any Shelf Registration Statement are
to be sold in an underwritten offering, the Managing Underwriters shall be
selected by the Majority Holders.

            (b) No person may participate in any underwritten offering pursuant
to any Shelf Registration Statement, unless such person (i) agrees to sell such
person's Securities or New Securities, as the case may be, on the basis
reasonably provided in any underwriting arrangements approved by the persons
entitled hereunder to approve such arrangements; and (ii) completes and executes
all questionnaires, powers of attorney, indemnities, underwriting agreements and

agreement with respect to its securities that is inconsistent with the rights
granted to the Holders herein or otherwise conflicts with the provisions hereof.

            9. Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, qualified,
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 the Holders of at least a majority of the then outstanding aggregate
principal amount of Securities (or, after the consummation of any Registered
Exchange Offer in accordance with Section 2 hereof, of New Securities); provided
that, with respect to any matter that directly or indirectly affects the rights
of any Initial Purchaser hereunder, the Company shall obtain the written consent
of each such Initial Purchaser against which such amendment, qualification,
supplement, waiver or consent is to be effective. Notwithstanding the foregoing
(except the foregoing proviso), a waiver or consent to departure from the
provisions hereof with respect to a matter that relates exclusively to the
rights of Holders whose Securities or New Securities, as the case may be, are
being sold pursuant to a Registration Statement and that does not directly or
indirectly affect the rights of other Holders may be given by the Majority
Holders, determined on the basis of Securities or New Securities, as the case
may be, being sold rather than registered under such Registration Statement.

            10. Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail,
telex, telecopier or air courier guaranteeing overnight delivery:

provisions contained herein, or the application thereof in any circumstances, is
held invalid, illegal or unenforceable in any respect for any reason, the
validity, legality and enforceability of any such provision in every other
respect and of the remaining provisions hereof shall not be in any way impaired
or affected thereby, it being intended that all of the rights and privileges of
the parties shall be enforceable to the fullest extent permitted by law.

            16. Securities Held by the Company and its Affiliates. Whenever the
consent or approval of Holders of a specified percentage of principal amount of
Securities or New Securities is required hereunder, Securities or New
Securities, as applicable, held by the Company or its Affiliates shall be
disregarded and deemed not to be outstanding in determining whether such consent
or approval was given by the Holders of such required percentage.

            17. Agent for Service; Submission to Jurisdiction; Waiver of
Immunities. By the execution and delivery of this Agreement, the Company (i)
acknowledges that it has, by separate written instrument, irrevocably designated

such documents and instruments, as may be necessary to continue such designation
and appointment of CT Corporation in full force and effect so long as any of the
Securities shall be outstanding. To the extent that the Company may have or

(whether through service of notice, attachment prior to judgment, attachment in
aid of execution, execution or otherwise) with respect to itself or its
property, it hereby irrevocably waives such immunity in respect of this
Agreement, to the fullest extent permitted by law.

ANNEX A

Each Broker-Dealer that receives New Securities for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Securities. The Letter of Transmittal
states that by so acknowledging and by delivering a prospectus, a Broker-Dealer
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act. This Prospectus, as it may be amended or supplemented from
time to time, may be used by a Broker-Dealer in connection with resales of New
Securities received in exchange for Securities where such Securities were
acquired by such Broker-Dealer as a result of market-making activities or other
trading activities. The Company has agreed that, starting on the date the
Exchange Offer is consummated (the "Expiration Date") and ending on the close of
business 180 days after the Expiration Date it will make this Prospectus
available upon request to any Broker-Dealer for use in connection with any such
resale. See "Plan of Distribution".

ANNEX B

Each Broker-Dealer that receives New Securities for its own account in exchange
for Securities, where such Securities were acquired by such Broker-Dealer as a
result of market-making activities or other trading activities, must acknowledge
that it will deliver a prospectus in connection with any resale of such New
Securities. See "Plan of Distribution".

ANNEX C

                              PLAN OF DISTRIBUTION

            Each Broker-Dealer that receives New Securities for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such New Securities. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a Broker-Dealer in connection with resales of New Securities received in
exchange for Securities where such Securities were acquired as a result of
market-making activities or other trading activities. We have agreed that,
starting on the Expiration Date and ending on the close of business 180 days
after the Expiration Date, we will make this Prospectus, as amended or
supplemented, available upon request to any Broker-Dealer for use in connection
with any such resale. In addition, until [   ], 20[ ] (90 days after the
effectiveness of the registration statement), all dealers effecting transactions
in the New Securities may be required to deliver a prospectus.

            We will not receive any proceeds from any sale of New Securities by
brokers-dealers. New Securities received by Broker-Dealers for their own account
pursuant to the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the New Securities or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated prices. Any such resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
Broker-Dealer and/or the purchasers of any such New Securities. Any
Broker-Dealer that resells New Securities that were received by it for its own
account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such New Securities may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit resulting
from any such resale of New Securities and any commissions or concessions
received by any such persons may be deemed to be underwriting compensation under
the Securities Act. The Letter of Transmittal states that by acknowledging that
it will deliver and by delivering a prospectus, a Broker-Dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act.

            For a period of 180 days after the Expiration Date, we will promptly
send additional copies of this Prospectus and any amendment or supplement to
this Prospectus to any Broker-Dealer that requests such documents in the Letter
of Transmittal. We have agreed to pay all expenses incident to the Exchange
Offer (including the expenses of one counsel for the Holders of the Securities)
other than commissions or concessions of any brokers or dealers and will
indemnify the holders of the Securities (including any Broker-Dealers) against
certain liabilities, including liabilities under the Securities Act.

and/or 508. S-K 502(b) legend must appear on the back cover.]

                              BASIC TOLL AGREEMENT
                                     BETWEEN
                      EMPRESA NACIONAL DE ELECTRICIDAD S.A.
                                       AND
                     COMPANIA NACIONAL DE TRANSMISION ELECTRICA S.A.

In Santiago, Chile, on October 23, 2000, between EMPRESA NACIONAL DE
ELECTRICIDAD S.A., hereinafter and indistinctly, ENDESA, represented by its
General Manager, Mr. Hector Lopez Vilaseco, both domiciled in Santiago at Calle
Santa Rosa No 76, Floor 17, and COMPANIA NACIONAL DE TRANSMISION ELECTRICA
S.A., hereinafter and indistinctly referred to as TRANSELEC, represented by its
General Manager, Mr. Guillermo Espinosa Ihnen, both domiciled in Santiago at
Calle Santa Rosa No 76, Floor 9, the following has been agreed:

ONE: PURPOSE.

The purpose of the present contract is to agree on the annual basic toll
payments that ENDESA is to pay to TRANSELEC for its power plants Canutillar
(nominal power of 145.0 MW), El Toro (nominal power of 400.00 MW), Antuco
(nominal power of 300.0 MW), Abanico (nominal power of 136.0 MV), Bocamina
(nominal power of 125.0 MV), Cipreses (nominal power of 101.4 MV), Isla
(nominalo power of 68.0 MV), Sauzal (nominal power of 76.8 MV), Sauzalito
(nominal power of 9.5 MV), Rapel (nominal power of 350.0 MV), Los Molles
(nominal power of 16.0 MV), Huasco (nominal power of 80.23 MV), Diego de Almagro
(nominal power of 23.75 MV), and Taltal (nominal power of 240.0 MW), hereinafter
referred to as ENDESA Power Plants, as of October 23, 2000.

The basic annual payments will entitle ENDESA to upload up to the maximum power
and energy production capacity of the ENDESA Power Plants, which capacities are
indicated in the preceding paragraph, to transmit it, and to download energy and
power by means of the facilities which form part of its area of influence.
ENDESA shall exercise this right in accordance with the provisions provided, to
said effect, by the Economic Load Dispatch Center of the Central Interconnected
System (the CDEC-SIC).

Likewise, such downloads without supplementary payments as ENDESA may make in
the area of influence of each one of its power plants and at all of the
junctions from which, under normal operating conditions of the system, net
physical transmissions occur toward such area of influence, once it has paid the
basic toll, are limited to:

a)    The firm power of the power plant, plus such power as may have been
      contracted with third parties that have paid the basic and supplementary
      tolls necessary for reaching the point of download;

b)    The total capacity of the transmission system involved, without the
      existence of any priority or order of preference in this respect between
      all the power plants that pay the basic toll.

ENDESA - TRANSELEC  Basic Toll Contract                                        1
<PAGE>

c)    At such limits as the CDEC-SIC may establish, in consideration of what is
      provided in Article 198 of the Regulation for the General Electric
      Services Law approved by Supreme Decree No 327 of the Ministry of Mining,
      dated December 12, 1997, hereinafter the Electric Regulation.

TWO: THE AREA OF INFLUENCE

The parties agree that the area of influence of the ENDESA Power Plants is
comprised of the segments that connect the upload buses of such power plants,
which, for the purposes of the present contract , correspond to those indicated
in Exhibit No 1, with the basic energy sub-station of the Central
Interconnected System, SIC. As of the date of signing of the present contract,
the mentioned basic energy sub-station corresponds to the Quillota sub-station
of TRANSELEC, according to the selection of basic energy sub-station contained
in the semi-annual setting of junction prices of April, 2000.

In the event that, in future junction pricing, the basic energy sub-station is
selected at another junction of the system, the extent of the area of influence
of the ENDESA Power Plants will be modified accordingly. Such modification will
govern commencing from the same month of junction pricing originating a change
in the location of the basic energy sub-station.

In line with the above, the parties agree that, as of October 23, 2000, the area
of influence of the ENDESA Power Plants is to be comprised of the segments
indicated in Exhibit No. 1 hereto.

THREE: ANRV + OMC

The parties agree that, during the period between October 23, 2000 and March 31,
2002, the values of the Annual Payment of New Replacement Values plus the
Operation and Maintenance Costs (the ANRV + OMC) for the facilities referred to
above, belonging to the area of influence of the ENDESA Power Plants, are those
indicated in Exhibit No. 1 hereto, expressed in thousands of dollars of the
United States of America of January 1, 1999.

FOUR: PRO-RATA AMOUNTS

The parties agree that the pro-rata amounts for the ENDESA Power Plants for the
October 23, 2000-March 31, 2002 period are those indicated in Exhibit No. 2
hereto.

FIVE: DEFINITION OF THE NEW REPLACEMENT VALUE

For the purposes of the present contract , the New Replacement Value for the
transmission facilities, hereinafter, and indistinctly, the NRV, will be
understood to mean the cost of renewing all of the works, facilities and
physical assets intended for the function of the transmission of electricity.

Renewal is understood to mean the activity of replacing the works, facilities
and physical assets presently in service with others with identical
characteristics. In the event that they are not available on the market, the
respective cost is to be that of the works, facilities and physical assets of
modern technology, and current cost, meant to fulfill the same function with the
same standards of service quality. In the case of the transmission lines, those
existing are considered with respect to the topographical layout, structures,
voltage, number of circuits, and electrical transmission capacity. In the case
of the sub-stations, consideration is given, in addition to the primary control
and protection equipment, to the auxiliary equipment, including that of the
auxiliary services, battery banks and emergency equipment, buildings meant to
house the equipment indicated, land, and general works.

The costs associated with the NRV's for the transmission lines and for the
sub-stations which constitute the area of influence of the ENDESA Power Plants
include the following items, which are

ENDESA - TRANSELEC  Basic Toll Contract                                        2
<PAGE>

set forth solely as examples, without this listing being restrictive:
engineering and design, construction management and inspection, easements and
compensations, supply of imported and domestic equipment and materials with the
respective entry tariffs, port charges and domestic and international freight,
construction and assembly of works and equipment, other financial and
administrative costs such as staggered interest, overhead expenses, and
operating capital.

For purposes of the valuation of the lines, the original copper wire is replaced
by one of aluminum with equivalent characteristics. In the valuation of the
sub-stations, the switches for large volumes of oil, for compressed air, and for
large volumes of SF6 gas have been valued as switches for small volumes of SF6
gas. The synchronous condensers are valued as if they were static condensers.

SIX: OPERATION AND MAINTENANCE COSTS

Operation and maintenance costs (OMC) take into consideration all of the costs
necessary for the adequate maintenance of the facilities and their proper
decentralized operation subordinate to the Zone Operation Centers (ZOC) and to a
Centralized Transmission Dispatch.

The OMC's take into consideration the operating expenses intended for the
planning, execution and control of the operation and maintenance activities,
being latter either preventative, scheduled as corrective, or non scheduled as
corrective, and the expenses and insurance against accidents in buildings and
facilities.

In addition, the OMC's include the costs of capital, of operation, and of
maintenance for the vehicles, for the maintenance equipment, for the
telecommunications systems, for the tools and for instruments necessary for
carrying out the operation and maintenance activities, including the remote
terminal units (RTU), the Zone Operation Centers (ZOC), and the Centralized
Transmission Dispatch. Likewise, the OMC's include costs of capital, of
operation, and of maintenance for the land and buildings, such as workshops,
offices, and warehouses meant for operation and maintenance.

SEVEN: ANNUAL BASIC TOLL PAYMENTS UP TO MARCH 31, 2002

The parties agree that, as of October 23, 2000, and up to March 31, 2002, under
the category of basic ANRV + OMC for its power plants, ENDESA will pay to
TRANSELEC such amount resulting from multiplying the sum of the annual payment
for the new replacement value (ANRV) and the operation and maintenance costs
(OMC) for each one of the facilities of the area of influence of the said power
plants by the pro-rata amount corresponding to said power plants.

As a result of the above, the parties agree that the annual basic toll payments
for the ENDESA Power Plants for the period from October 23, 2000 to March 31,
2002, net of VAT, which ENDESA is to pay to TRANSELEC, are those indicated in
Table No 1 below. These annual payments, which calculation is indicated in
Exhibit No 3 hereto, are expressed in dollars of the United States of America
as of January 1, 1999.

The values contained in Table No 1 above take into consideration that, as of
October 23, 2000 the area of influence of the ENDESA Power Plants extends from
the download bus of the power plant to the Quillota sub-station of TRANSELEC.

EIGHT: ANNUAL BASIC TOLL PAYMENTS COMMENCING FROM APRIL 1, 2002

Starting from April 1, 2002, and until the date when a modification of the
present basic toll contract may start to govern, arising as indicated in Clause
TWELVE, the amount of the basic toll that ENDESA will pay to TRANSELEC will be
calculated by considering the following for each one of the power plants
thereof:

a)    The facilities which comprise the area of influence thereof as established
      by the Board of Directors of the CDEC - SIC in accordance with the
      Electric Regulation Article 176, letter b)

b)    The values of basic tolls per unit of firm power for each segment,
      calculated by the Tolls Administration of the CDEC - SIC, as provided in
      letter h) of Article 182 of the Electric Regulation. For such purposes,
      the NRV's and OMC's indicated in letter d) below will be considered.

c)    The firm power calculated by the Operations Department of the CDEC - SIC
      as indicated in letter f) of Article 181 of the Electric Regulation.

      In the event that the CDEC - SIC has not calculated the firm power of the
      power plants of the SIC, the most recent values of firm power of the
      ENDESA power plants which were in force on such date will be provisionally
      applied.

d)    The New Replacement Values (NRV's) and the Operation and Maintenance Costs
      (OMC's) published by TRANSELEC in the book of same name, July 1999
      edition, duly indexed according to the formulas contained in said
      publication.

ENDESA - TRANSELEC  Basic Toll Contract                                        4
<PAGE>

e)    The calculation of the basic toll for ENDESA will be made on an annual
      basis and the new value will take effect between the months of April of
      each year and March of the following year.

NINE: PAYMENT MODALITY.

The basic ANRV + OMC's will be paid in twelve monthly payments upon accrual each
month, equivalent to multiplying the value of the basic ANRV + OMC indicated for
each period and power plant in Table No. 1 above, or the basic tolls resulting
from applying what is provided in Clause EIGHT, duly indexed as provided in
Clause TEN, by the factor of 0.07974 (seven thousand nine hundred seventy-four
one-hundred-thousandths) and converted into pesos of domestic currency by
employing the exchange rate corresponding to the "observed dollar" referred to
in the first paragraph of No 6, Chapter I, Title I, of the Compendium of
International Currency Exchange Rules published by the Central Bank of Chile, or
such as may replace it in the future, at the average for the month corresponding
to payment. The value Added Tax will be charged separately to the payment thus
stipulated.

TRANSELEC will send the invoice within the first five (5) business days of the
month subsequent to the month to which the charge pertains. ENDESA undertakes to
pay such invoice to the treasury of TRANSELEC in Santiago, in cash, by check,
not crossed, within the banking region of Santiago, or bank sight note, at
latest prior to noon on the sixteenth day of each month subsequent to the month
to which the charge pertains. If such day is a Saturday, Sunday or holiday, the
time due will extend up to noon on the subsequent business day.

Nevertheless, the parties may agree to a different method of payment, which may
be by a bank transfer of funds or deposits into any of the checking accounts of
TRANSELEC. In such case ENDESA must inform TRANSELEC in writing as to the date,
amount, checking account number, and bank through which the payment or deposit
has been made, as well as the number of the invoice or invoices that it has
paid.

In the case of default or simple delay in payment, interest will accrue at the
maximum contractual rate for transactions that are not adjustable of less than
or more than ninety (90) days, as the case may be, from the date when the
default or simple delay took place and up to the date of the actual payment
thereof.

In the event that TRANSELEC delays de delivery of the invoice, ENDESA will be
able to postpone its payment by one day for each day of delay and such
postponement will not be deemed to be a default or simple delay for the purposes
of charging the interest referred to in the preceding paragraph.

TEN: INDEXATION

The parties agree that the monthly payments pertaining to the annual basic toll
amounts for the ENDESA Power Plants are to be indexed semi-annually on January 1
and on July 1 of each year, by multiplying the monthly payment in force for the
previous month by such factor as may result from applying the formula for
indexing tolls detailed in Exhibit No. 4 hereto. For these purposes, the said
indexing factor will be deemed to be rounded off to the fifth decimal.

The first indexation will take place on July 1, 2000 and will cover the period
between January 1, 1999 and June 30, 2000. The parties agree that the indexing
factors corresponding to the first and second semi-annual periods of 1999 and to
the first semi-annual period of 2000 are 0.95896, 0.94468 and 1.04100,
respectively.

ENDESA - TRANSELEC  Basic Toll Contract                                        5
<PAGE>

Whenever a semi-annual indexation of tolls applies, TRANSELEC will prepare and
will send to ENDESA a memorandum of calculation containing, in a detailed and
documented manner, the value of the new monthly payment. The submittal of this
document shall take place five (5) business days before the date of delivery of
the invoices corresponding to the months of January and July of each year.

ELEVEN: SETTLEMENT OF THE VIRT's

The parties agree that they will carry out a monthly settlement, between
themselves, of the valuation of the uploads and downloads per segment (VIRT's)
for each one of the segments indicated in Clause TWO generated in balances of
uploads and downloads made by the CDEC - SIC for each one of the said segments.
The mentioned settlement will be carried out during the month subsequent to the
month to which the settlement pertains, once TRANSELEC has actually received
such amounts from the rest of the members of the CDEC - SIC. In the event that
the CDEC - SIC has not determined the VIRT's or that TRANSELEC has not received
all or part of the VIRT's from the rest of the members of the CDEC - SIC, the
parties may agree on provisional settlements under this category, on account
against final payment.

The amount to be paid for the settlement of the VIRT's will be equal to the VIRT
of each segment multiplied by the pro-rata amount of ENDESA for such segment. If
the amount of the settlement corresponding to the entirety of the segments
indicated in Clause TWO proves to be greater than zero, TRANSELEC will pay such
amount to ENDESA plus VAT; conversely, if the amount of the total settlement
proves to be less than zero, ENDESA will pay the absolute value of such amount,
plus VAT, to TRANSELEC. For purposes of these settlements, if appropriate, the
same interest rate as that applied by the CDEC - SIC.

If in the period subsequent to March 30, 2002, such basic tolls as ENDESA may
pay to TRANSELEC take consideration of the discount of the rate revenues
estimated by the Administration of Tolls of the CDEC - SIC, the latter will be
settled by readjustment between the parties in a monthly manner by applying that
provided for in the present clause, but relating to the discounted rate revenues
values.

TWELVE: PERIOD OF EFFECTIVENESS

The present contract will have an unlimited period of effectiveness commencing
from October 23, 2000.

Notwithstanding what is provided in the previous paragraph, either of the
parties may request from the other party in writing, as of January 1, 2006, a
partial or total revision of the contract.

Revision of the present contract must be anticipated if legal changes arise in
the Statutory Decree with (M) No 1/82, Articles 51, 51A to 51F thereof, in such
manner as to adapt the contract to such legal changes. Revision of the contract
for this reason may be requested by either of the parties and will take effect
once the legal modifications enter into force.

Likewise, if the parties would not reach an agreement with the modifications to
the present contract arising from such general or partial revision as either of
the parties may request commencing from January 1, 2006, within a term of six
months from the date of receipt of such request, the parties agree to submit the
difference to the arbitrating instance provided in Clause EIGHTEEN. The contract
will be modified under the terms pronounced by such arbitrating instance.

In no case will a gap arise in the payments that ENDESA makes to TRANSELEC. In
the event that methodological or regulatory absences of definition exist
deriving from legal modifications, the monthly payments will continue to be made
on the basis of the present contract in a provisional

ENDESA - TRANSELEC  Basic Toll Contract                                        6
<PAGE>

manner subject to adjusted settlement until such time as such absences of
definitions are resolved by mutual agreement between the parties or in
accordance with the procedure established in Clause EIGHTEEN.

The respective modification of the basic toll, whether arising by agreement of
the parties or by decision of the arbitration panel, will govern from the time
when the event causing such revision arises or enters into force, giving rise to
such monthly settlement readjustments as may pertain. The differences will be
paid, if appropriate, by such party as proves to be the debtor, with the
interest current for transactions that are not adjustable of more than or less
than 90 days, as may pertain, within a maximum term of 30 days subsequent to the
time when the contract arises or the arbitration ruling is executed.

THIRTEEN: REVISIONS OF THE BASIC TOLL

The parties agree that, in the period prior to March 31, 2002, the value of the
basic toll under the present contract can solely and exclusively be revised to
incorporate the effects caused by:

a)    The connection of new power plants to the SIC which are not included in
      the Works Plan considered for the calculation of the toll.
b)    Change in the direction of the flow toward the basic energy sub-station of
      the SIC under typical operating conditions.
c)    A failure to materialize, delays or accelerations in projects contemplated
      in the Works Plan considered in the calculation of the toll.
d)    An increase in the capacity of any of the ENDESA Power Plants.
e)    Changes in the capacity of existing power plants.
f)    Disconnection, under the conditions indicated in Article 167 of the
      Electric Regulation, or a change in the point of connection of existing
      power plants.
g)    Modifications to the facilities within the area of influence of the ENDESA
      Power Plants caused by the addition or removal of TRANSELEC facilities.
h)    Acceleration or delay in the transmission works projected in the basic
      toll calculated.

For purposes of what provided in the present clause, reference is to be made to
the conditions employed in the application of the ENDESA / TRANSELEC - COLBUN
arbitration resolution dated January 20, 1999, contained in Exhibit No. 1 to the
report on the contract between TRANSELEC and COLBUN, approved by that Court of
Arbitration on April 15, 1999. Exception is made to the basic toll for the
Taltal power plant, which calculation has been done by employing the bases
included in Exhibit No. 5 hereto.

Revision because of any of the reasons indicated will commence by the interested
party's sending to the other party a written report containing the technical and
economic reasons justifying it. The addressee party of the report will have a
maximum term of 30 consecutive days to analyze and respond to the report.

In the event that the indicated report is rejected, whether expressly or due to
the passage of the term of 30 days without the issuance of a response, it will
be deemed that a disagreement exists with respect to the modification proposed.
In such case, the parties will seek to resolve the differences directly. If
further 30 days elapse and no agreement has been reached, either of the parties
will be able to resort to the arbitration panel provided for in Clause EIGHTEEN
in order to resolve the dispute.

The respective modification to the basic toll, whether arising upon agreement by
the parties or from a decision of the court of arbitration, will govern from the
time when the event causing such revision arises or enters into force, giving
rise to such monthly settlement readjustments as may pertain. The differences
will be paid, if appropriate, by such party that proves to be the debtor, with
the interest

ENDESA - TRANSELEC  Basic Toll Contract                                        7
<PAGE>

current for transactions that are not adjustable of more than or less than 90
days, as may pertain, within a maximum term of 30 days subsequent to the time
when the contract arises or the arbitration ruling is executed.

In no case will a gap arise in the payments that ENDESA makes to TRANSELEC. In
the event that methodological or regulatory absences of definition exist
deriving from legal modifications, the monthly payments will continue to be made
on the basis of the present contract in a provisional manner subject to adjusted
settlement until such time as such absences of definitions are resolved by
mutual agreement between the parties or in accordance with the procedure
established in Clause EIGHTEEN.

Any modification at the facilities which comprise the area of influence or the
pro-rata amounts of the ENDESA Power Plants arising from a revision of the toll
provided in the present clause will, as a result, give rise to the modification
to Exhibits No. 1, No. 2 or No. 3, as appropriate.

The parties agree that the procedure for revising the value of the basic toll
which they have agreed to in the present clause will apply in serious cases
involving significant imbalances in the susceptibility of the contract to
commutation, that is, it will only be applied in instances where it is
ascertained that the economic effect of one or more of the causes defined in
letters a) to h) above, represents an increase or decrease by at least 5% (five
percent) of the value of the annual basic toll payment in force at the time when
the cause or causes giving rise to such revision took place. In order to
determine the percentage of the increase or decrease in the annual payment
indicated, the number of power plants and their diversity in terms of
geographical location have been taken into account.

Notwithstanding what is stated in this clause, in the event that in future
junction pricing, a basic energy sub-station at another junction of the system
is selected, the extent of the area of influence for the ENDESA Power Plants
will be modified accordingly, as provided in Clause TWO hereof.

FORTEEN: LIABILITIES

The liabilities of the contracting parties will be those defined in Statutory
Decree No. 1 of 1982, of the Ministry of Mining, hereinafter the Electric Law,
the Electric Regulation, the manuals and procedures of the CDEC - SIC, and the
modifications or changes to the mentioned legal texts.

TRANSELEC will, at no time, be liable for such damages or losses as ENDESA may
suffer due to a total or partial lack of supply of electrical energy and power,
excessive variations in voltage or frequency, or others caused by technical
failures which may affect the facilities of the Transmission System of TRANSELEC
(SIT), or due to any other event that may interrupt, shut down or disturb
transmissions of energy or power at the facilities of the area of influence of
the ENDESA Power Plants, caused by an act of God or force majeure and, without
the listing below being restrictive, by the following: damage caused by natural
phenomena, earthquakes, lightning, storms, falling trees, floods, and mudflows,
among others.

On its part, ENDESA will in no case, be liable for such losses as TRANSELEC may
suffer due to technical failures or any other event which may interrupt, shut
down or disturb the generating or transmission of energy and power at the ENDESA
Power Plants, caused by an act of God or force majeure. Among other things, an
act of God or force majeure will be deemed as being the occurrence of a
prolonged drought that impedes the normal generation of energy.

FIFTEEN: SUSPENSION OF SERVICE

TRANSELEC may suspend the transmission of energy and power for purposes of
scheduled modification or maintenance activities. Such suspensions will be
planned and scheduled by TRANSELEC upon hearing the opinions on the matter from
the various generating companies

ENDESA - TRANSELEC  Basic Toll Contract                                        8
<PAGE>

affected by such supply interruption. Such suspensions shall be communicated by
TRANSELEC to ENDESA in writing, with at least sixty (60) days in advance.

Service suspensions will be governed by the Electric Law, by the Electric
Regulation, and by the rules and regulations of the CDEC - SIC.

TRANSELEC may also suspend the transmission of energy and power for repair and
emergency purposes. Such suspensions will take place by giving a notice to
ENDESA as far in advance as the circumstances permit.

SIXTEEN: INFORMATION ON OPERATION

TRANSELEC undertakes to send to ENDESA, each time that events affecting the
normal functioning of the transmission facilities of the area of influence of
the ENDESA Power Plants take place, a report indicating the irregularities
and/or service interruptions occurring at such facilities, before 12:00 a.m. on
the day subsequent to the occurrence of the event. The aforementioned report
will indicate the duration of the interruptions that may have arisen at the
facilities in the area of influence of the ENDESA Power Plants and an estimate
of the energy interrupted through such facilities, the day and time when they
occurred. Same report or another supplementary report will indicate the causes
of the irregularities.

SEVENTEEN: AVAILABILITY OF THE SYSTEM

TRANSELEC undertakes to comply with such service quality standards as may be
established by the Electric Law, the Electric Regulation, the manuals and
procedures of the CDEC - SIC, and the modifications or changes to the mentioned
texts, which in no event will be lower than the historical standards existing as
of the date of this contract, measured as the average of the Equivalent
Interruption Time (TEI) from Internal Causes recorded in 1995 to 1999, as
specified in the 1999 annual report by TRANSELEC. Such average TEI for Internal
Causes amounts to 15.9 minutes.

In the event that a failure to comply with this index is detected for two
consecutive years, TRANSELEC undertakes to hire an external technical auditing
firm appointed upon mutual agreement between the parties, that will evaluate and
make recommendations on the operational and maintenance practices followed by
TRANSELEC. The recommendations issued by the auditing firm shall be implemented
by TRANSELEC.

EIGHTEEN: ARBITRATION

Any controversy that may arise between the parties relating to the
interpretation, performance or breach, application, or termination of the
present contract will be resolved by the Court of Arbitration convened as
provided in Article 51 G of Statutory Decree No. 1 of 1982, of the Ministry of
Mining.

It is expressly established that, if one of the parties refuses to designate or
delays in the designation of the arbitrator whom it is responsible for
appointing, the other party may resort to the regular courts of law to proceed
with the appointment thereof. It will be understood that a refusal or delay
exists when the term of twenty (20) days indicated in the third paragraph of the
mentioned Article 51 G has elapsed and the party has not made such designation.

Likewise, the parties leave on record that if the arbitrators do not agree on
the designation of the third arbitrator within the term referred to above, such
designation will be made by the Regular Court of Justice of the Borough of
Santiago, in which case the appointment shall necessarily fall upon an attorney
at law who has been a member of the Supreme Court or the Court of Appeals for
Santiago, or Dean or Director of the University of Chile or Pontifica
Universidad Catolica de Chile Law School.

ENDESA - TRANSELEC  Basic Toll Contract                                        9
<PAGE>

Once arbitration is been convened, the arbitrator shall resolve, as the first
remedy, within a term shorter than 60 days, on the amount that ENDESA must
continue to pay TRANSELEC on a provisional basis, while the controversy is
finally resolved.
