          2.  Registered Exchange Offer; Resales of New Securities by Exchanging
              ------------------------------------------------------------------
Dealers; Private Exchange.
- --------------------------

          (a)  The Company shall prepare and, not later than 90 days after the
date of the original issuance of the Securities, shall file with the Commission
the Exchange Offer Registration Statement with respect to the Registered
Exchange Offer.  The Company shall use its best efforts to cause the Exchange
Offer Registration Statement to become effective under the Securities Act within
150 days after 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
Securities do not constitute a portion of an unsold allotment acquired by such
Holder directly from the Company and such Holder is not an affiliate of the
Company within the meaning of the Securities Act, acquires the New Securities in
the ordinary course of such Holder's business and has no arrangements with any
person to participate in the distribution of the New Securities) to trade such
New Securities from and after their receipt without any limitations or
restrictions under the Securities 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 30 days
     after the date notice thereof is mailed to the Holders (or longer if
     required by applicable law);


                                                                               6

          (iii) utilize the services of a depositary for the Registered Exchange
     Offer with an address in the Borough of Manhattan, The City of New York;
     and

          (iv)  comply in all material 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 tendered and not validly
     withdrawn pursuant to the Registered Exchange Offer;

          (ii)  deliver to the Trustee for cancelation all Securities so
     accepted for exchange; and

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

          (e)   The Purchasers and the Company acknowledge that, pursuant to
current interpretations by the Commission's staff of Section 5 of the Securities
Act, and in the absence of an applicable exemption therefrom, each Exchanging
Dealer is required to deliver a Prospectus in connection with a sale of any New
Securities received by such Exchanging Dealer pursuant to the Registered
Exchange Offer in exchange for Securities acquired for its own account as a
result of market-making activities or other trading activities.  Accordingly,
the Company shall:


                                                                               7

          (i)  include the information set forth in Annex A hereto on the cover
     of the Exchange Offer Registration Statement, in Annex B hereto in the
     forepart of the Exchange Offer Registration Statement in a section setting
     forth details of the Exchange Offer, in Annex C hereto in the underwriting
     or plan of distribution section of the Prospectus forming a part of the
     Exchange Offer Registration Statement, and in Annex D hereto in the Letter
     of Transmittal delivered pursuant to the Registered Exchange Offer (it
     being understood that a Holder's participation in the Exchange Offer is
     conditioned on the Holder, by executing and returning the Letter of
     Transmittal, representing in writing to the Company as set forth in Rider B
     of Annex D hereto); and

          (ii) use its best efforts to keep the Exchange Offer Registration
     Statement continuously effective under the Securities Act during the
     Exchange Offer Registration Period for delivery by Exchanging Dealers in
     connection with sales of New Securities received pursuant to the Registered
     Exchange Offer, as contemplated by Section 4(h) below.

          (f)  In the event that any 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 Purchaser, the Company shall issue and deliver to such Purchaser
or the party purchasing New Securities registered under a Shelf Registration
Statement as contemplated by Section 3 hereof from such Purchaser, in exchange
for such Securities, a like principal amount of New Securities.  The Company
shall seek 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.


                                                                               8

          3.  Shelf Registration.  If, (i) because of 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, or (ii) for
any other reason the Exchange Offer Registration Statement is not declared
effective within 150 days after the Closing Date or the Registered Exchange
Offer is not consummated within 180 days after the Closing Date, or (iii) any
Purchaser so requests with respect to Securities (or any New Securities received
pursuant to Section 2(f)) not eligible to be exchanged for New Securities in a
Registered Exchange Offer or, in the case of any Purchaser that participates in
any Registered Exchange Offer, such Purchaser does not receive freely tradable
New Securities, or (iv) any Holder (other than a Purchaser) is not eligible to
participate in the Registered Exchange Offer or (v) in the case of any such
Holder that participates in the Registered Exchange Offer, such Holder does not
receive freely tradable New Securities in exchange for tendered securities,
other than by reason of such Holder being an affiliate of the Company within the
meaning of the Securities Act (it being understood that, for purposes of this
Section 3, (x) the requirement that a Purchaser deliver a Prospectus containing
the information required by Items 507 and/or 508 of Regulation S-K under the
Securities Act in connection with sales of New Securities acquired in exchange
for such Securities shall result in such New Securities being not "freely
tradeable" but (y) the requirement that an Exchanging Dealer deliver a
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 following provisions shall apply:


                                                                               9

          (a)  The Company shall as promptly as practicable (but in no event
more than the later of (i) 90 days after the Closing Date or (ii) 45 days after
so required or requested pursuant to this Section 3), file with the Commission
and thereafter shall use its best efforts to cause to be declared effective
under the Securities Act a Shelf Registration Statement relating to the offer
and sale of the Securities or the New Securities, as applicable, by the Holders
from time to time in accordance with the methods of distribution elected by such
Holders and set forth in such Shelf Registration Statement (such Securities or
New Securities, as applicable, to be sold by such Holders under such Shelf
Registration Statement being referred to herein as "Registration Securities");
provided, however, that, with respect to New Securities received by a 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 Regulation S-K Items 507 and/or 508, as
applicable, in satisfaction of its obligations under this paragraph (a) 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.

          (b)  The Company shall use its 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
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 best efforts to keep the Shelf Registration Statement effective
during the Shelf Registration 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 (i) such action is required
by applicable law or (ii) such action is taken by the Company in good faith and
for valid business reasons


                                                                              10

(not including avoidance of the Company's obligation 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.   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)  (i)  The Company shall furnish to you, prior to the filing
     thereof with the Commission, a copy of any Exchange Offer Registration
     Statement, each amendment thereof and each amendment or supplement, if any,
     to the Prospectus included therein and shall use its best efforts to
     reflect in each such document, when so filed with the Commission, such
     comments as you reasonably may propose.

          (ii) The Company shall furnish to you, prior to the filing thereof
     with the Commission, a copy of any Shelf Registration Statement, each
     amendment thereof and each amendment or supplement, if any, to the
     Prospectus included therein and shall use its best efforts to reflect in
     each such document, when so filed with the Commission, such comments as any
     Holder whose securities are to be included in such Shelf Registration
     Statement reasonably may propose.

          (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
     Securities Act and the rules and regulations thereunder, (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 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


                                                                              11

     therein, in the light of the circumstances under which they were made, not
     misleading.

          (c)  (1)  The Company shall advise you and, in the case of a Shelf
     Registration Statement, the Holders of securities covered thereby, and, if
     requested by you or any such Holder, confirm such advice in writing:

               (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; and

               (ii)  of any request by the Commission for amendments or
          supplements to the Registration Statement or the Prospectus included
          therein or for additional information.

          (2)  The Company shall advise you and, in the case of a Shelf
     Registration Statement, the Holders of securities covered thereby, and, in
     the case of an Exchange Offer Registration Statement, any Exchanging Dealer
     which 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 Exchanging Dealer, confirm such advice in writing:

               (i)   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;

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

               (iii) of the happening of any event that requires the making of
          any changes 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


                                                                              12

          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 (which advice
          shall be accompanied by an instruction to suspend the use of the
          Prospectus until the requisite changes have been made).

     Each such Holder or Exchanging Dealer agrees by its acquisition of such
     securities to be sold by such Holder or Exchanging Dealer, that, upon being
     so advised by the Company of any event described in clause (iii) of this
     paragraph (c)(2), such Holder or Exchanging Dealer will forthwith
     discontinue disposition of such securities under such Registration
     Statement or Prospectus, until such Holder's or Exchanging Dealer's receipt
     of the copies of the supplemented or amended Prospectus contemplated by

     that the use of the applicable Prospectus may be resumed.

          (d)  The Company shall use its best efforts to obtain the withdrawal
     of any order suspending the effectiveness of any Registration Statement at
     the earliest possible time.

          (e)  The Company shall furnish to each Holder of securities included
     within the coverage of any Shelf Registration Statement, without charge, at
     least one copy of such Shelf Registration Statement and any post-effective
     amendment thereto, including financial statements and schedules, and, if
     the Holder so requests in writing, any documents incorporated by reference
     therein and all exhibits thereto (including those incorporated by reference
     therein).

          (f)  The Company shall, during the Shelf Registration Period, deliver
     to each Holder of securities included within the coverage of any Shelf
     Registration Statement, without charge, as many copies of the Prospectus
     (including each preliminary Prospectus) included in such Shelf Registration

     reasonably request; and the Company


                                                                              13

          (g)  The Company shall furnish to each Exchanging Dealer which so
     requests, without charge, at least one copy of the Exchange Offer

     all exhibits thereto (including those incorporated by reference therein).

          (h)  The Company shall, during the Exchange Offer Registration Period,
     promptly deliver to each Exchanging Dealer, without charge, as many copies
     of the Prospectus included in such Exchange Offer Registration Statement
     and any amendment or supplement thereto as such Exchanging Dealer may
     reasonably request for delivery by such Exchanging Dealer in connection
     with a sale of New Securities received by it pursuant to the Registered
     Exchange Offer; and the Company consents to the use of the Prospectus or
     any amendment or supplement thereto by any such Exchanging Dealer, as
     aforesaid.

          (i)  Prior to the Registered Exchange Offer or any other offering of
     securities pursuant to any Registration Statement, the Company shall
     register or qualify or cooperate with the Holders of securities included
     therein and their respective counsel in connection with the registration or

     jurisdiction where it is not then so qualified or to take any action which
     would subject it to general


                                                                              14

     service of process or to taxation 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 of certificates representing
     Securities to be sold pursuant to any Registration Statement free of any
     restrictive legends and in such denominations and registered in such names
     as Holders may request prior to sales of securities pursuant to such
     Registration Statement.

          (k)  Upon the occurrence of any event contemplated by paragraph
     (c)(2)(iii) above, the Company shall promptly prepare a post-effective
     amendment to any Registration Statement or an amendment or supplement to
     the related Prospectus or file any other required document so that, as
     thereafter delivered to purchasers of the 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.

          (l)  Not later than the effective date of any such Registration
     Statement hereunder, the Company shall provide a CUSIP number for the
     Securities or 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, if requested by the
     applicable Holder or Holder's Counsel, eligible for deposit with The
     Depository Trust Company or any successor thereto under the Indentures.

          (m)  The Company shall use its best efforts to comply with all
     applicable rules and regulations of the Commission to the extent and so
     long as they are applicable to the Registered Exchange Offer or the Shelf
     Registration and will make generally available to its security holders a
     consolidated earnings statement (which need not be audited) covering a
     twelve-month period commencing after the effective date of the Registration
     Statement and ending not later than 15 months thereafter, as soon as
     practicable after the


                                                                              15

     end of such period, which consolidated earnings statement shall satisfy the
     provisions of Section 11(a) of the Securities Act.

          (n)  The Company shall cause the Indentures to be qualified under the
     Trust Indenture Act of 1939, as amended, on or prior to the effective date
     of any Shelf Registration Statement or Exchange Offer Registration
     Statement.

          (o)  The Company may require each Holder of securities to be sold
     pursuant to any Shelf Registration Statement to furnish to the Company in
     writing 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 Registration Statement.  The Company may exclude from any
     such Registration Statement the securities of any such Holder who fails to
     furnish such information within a reasonable time after receiving such
     request.  Each Holder as to which any Shelf Registration is being effected
     agrees to furnish promptly to the Company all information required to be
     disclosed in order to make the information previously furnished to the
     Company by such Holder not materially misleading.

          (p)  The Company shall, if requested, promptly incorporate in a
     Prospectus supplement or post-effective amendment to a Shelf Registration
     Statement, such information as the Managing Underwriters, if any, and
     Majority Holders reasonably agree should be included therein and shall make
     all required filings of such Prospectus supplement or post-effective
     amendment as soon as notified of the matters to be incorporated in such
     Prospectus supplement or post-effective amendment.

     (q)  (i)  In the case of any Shelf Registration Statement, the Company
     shall enter into such agreements (including underwriting agreements) and
     take all other appropriate actions in order to expedite or facilitate the
     registration or the disposition of the Securities, and in connection
     therewith, if an underwriting agreement is entered into, cause the same to
     contain indemnification provisions and procedures no less


                                                                              16

     favorable than those set forth in Section 6 hereof (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 hereof from Holders of Securities to the
     Company.

               (ii) Without limiting in any way paragraph (q)(i), no Holder may
     participate in any underwritten registration hereunder unless such Holder
     (x) agrees to sell such Holder's securities to be covered by such
     registration on the basis provided in any underwriting arrangements
     approved by the Majority Holders and the Managing Underwriters and (y)
     completes and executes in a timely manner all customary questionnaires,
     powers of attorney, underwriting agreements and other documents reasonably
     required by the Company or the Managing Underwriters in connection with
     such underwriting arrangements.

          (r)  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 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 reasonably requested by such
     person; (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
     Registration Statement as is customary for due diligence examinations in
     connection with primary underwritten offerings; provided, however, that any
                                                     --------  -------
     information that is nonpublic 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


                                                                              17

     accompanying obligation of confidentiality; (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; (iv) obtain
     opinions of counsel to the Company (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
     underwriters, if any, 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 underwriters; (v) obtain "cold
     comfort" letters (or, in the case of any person that does not satisfy the
     conditions for receipt of a "cold comfort" letter specified in Statement on
     Auditing Standards No. 72, an "agreed-upon procedures" letter under
     Statement on Auditing Standards No. 35) 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 or
     incorporated by reference in the Registration Statement), addressed to each
     selling Holder of securities registered thereunder and the underwriters, if
     any, in customary form and 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 foregoing actions set forth in
     clauses (iii), (iv), (v) and (vi) of this Section 4(r) shall be performed
     (A) on the effective date of such Registration Statement and each post-
     effective amendment thereto and (B) at each closing under any underwriting
     or similar agreement as and to the extent required thereunder.


                                                                              18

          (s)  In the case of any Exchange Offer Registration Statement, the
     Company shall (i) make reasonably available for inspection by each
     Purchaser, and any attorney, accountant or other agent retained by such
     Purchaser, all relevant financial and other records, pertinent corporate
     documents and properties of the Company and its subsidiaries reasonably
     requested by such person; (ii) cause the Company's officers, directors and
     employees to supply all relevant information reasonably requested by such
     Purchaser or any such attorney, accountant or agent in connection with any
     such Registration Statement as is customary for due diligence examinations
     in connection with primary underwritten offerings; provided, however, that
                                                        --------  -------
     any information that is nonpublic at the time of delivery of such
     information shall be kept confidential by such 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; (iii) make such representations
     and warranties to such Purchaser, in form, substance and scope as are
     customarily made by issuers to underwriters in primary underwritten
     offerings; (iv) obtain opinions of counsel to the Company (which counsel
     and opinions (in form, scope and substance) shall be reasonably
     satisfactory to such Purchaser and its counsel), addressed to such
     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 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 or incorporated by
     reference in the Registration Statement), addressed to such 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 Purchaser or its counsel in lieu


                                                                              19

     of a "cold comfort" letter, an agreed-upon procedures letter under
     Statement on Auditing Standards No. 35, covering matters requested by such
     Purchaser or its counsel; and (vi) deliver such documents and certificates
     as may be reasonably requested by such 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 4(s) shall be
     performed (A) at the close of the Registered Exchange Offer and (B) on the
     effective date of any post-effective amendment to the Exchange Offer
     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 (in addition to one local counsel in each relevant jurisdiction)
designated by the Majority Holders to act as counsel for the Holders in
connection therewith ("Holders' Counsel").  Notwithstanding the foregoing, the
Holders of the securities being registered shall pay all agency or brokerage
fees and commissions and underwriting discounts and commissions attributable to
the sale of such securities and the fees and disbursements of any counsel or
other advisors or experts retained by such holders (severally or jointly), other
than the counsel and experts specifically referred to above in this Section 5,
transfer taxes on resale of any of the securities by such Holders and any
advertising expenses incurred by or on behalf of such Holders in connection with
any offers they may make.

          6.   Indemnification and Contribution.  (a)  In connection with any
               ---------------------------------
Registration Statement, the Company agrees to indemnify and hold harmless each
Holder of securities covered thereby (including each Purchaser and, with respect
to any Prospectus delivery as contemplated in Section 4(h) hereof, each
Exchanging Dealer), the directors, officers, employees and agents of each such
Holder and each other person, if any, who controls any such Holder within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act
against any and all losses, claims, damages or liabilities, joint or several, to
which


                                                                              20

they or any of them may become subject under the Securities 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 the Registration Statement as
originally filed or in any amendment thereof, or in any preliminary Prospectus
or 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 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 specifically for inclusion therein; provided further, however, that the
                                           ----------------  -------
indemnity agreement contained in this Section 6(a) shall not inure to the
benefit of any indemnified party to the extent that it is determined by a final,
non-appealable judgment that (i) a preliminary Prospectus contained an untrue
statement of a material fact or omitted to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, (ii) the sale to the person asserting any such losses, claims,
damages or liabilities was an initial resale of securities by any Holder, (iii)
any such loss, claim, damage or liability of such indemnified party results from
the fact that there was not sent or given to such person, at or prior to the
written confirmation of the sale of such securities to such person, a copy of
any revised preliminary Prospectus, the related Prospectus or the related
Prospectus as amended or supplemented in any case where such delivery is
required by the Securities Act, and the Company had previously furnished copies
thereof to such Holder and (iv) the revised preliminary Prospectus, the related
Prospectus or the related Prospectus as amended or supplemented corrected such
untrue statement or omission.


                                                                              21

This indemnity agreement will be in addition to any liability which the Company
may otherwise have.

          The Company also agrees to indemnify or contribute to Losses (as
defined below) of, as provided in Section 6(d), any underwriters of Securities
registered under a Shelf Registration Statement, their officers, directors,
employees and agents and each person who controls such underwriters on
substantially the same basis as that of the indemnification of the 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(q) hereof.

          (b)  Each Holder of securities covered by a Registration Statement
(including each Purchaser and, with respect to any Prospectus delivery as
contemplated in Section 4(h) hereof, each Exchanging Dealer) severally and not
jointly agrees to indemnify and hold harmless the Company, each of its directors
and officers and each other person, if any, who controls the Company within the
meaning of Section 15 of the Securities Act or Section 20 of 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, 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 and to the extent it did not
otherwise learn of such action and 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


                                                                              22

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 (and local 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 reasonably satisfactory to the indemnified party to represent
the indemnified party within a reasonable time after notice of the institution
of such action 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 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. It is understood,
however, that the Company shall, in connection with any one such action or
separate but substantially similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of only one


                                                                              23

separate firm of attorneys (in addition to any local counsel) at any time for
all such Holders and controlling persons. An indemnifying party shall not be
liable under this Section 6 to any indemnified party regarding any settlement 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 sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent is consented to by such
indemnifying party, which consent shall not be unreasonably withheld.

          (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, in
lieu of indemnifying such indemnified 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 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 which 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


                                                                              24

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 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 Securities
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 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 parties agree that it would not be just and equitable if contribution
were determined by pro rata allocation 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
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section 6,
each person who controls a Holder within the meaning of either the Securities
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 Securities Act
or the Exchange Act, each officer of the Company who shall have signed the
Registration Statement and each director of the Company shall have the same
rights to contribution as the Company,


                                                                              25

subject in each case to the applicable terms and conditions of this paragraph
(d).

          (e)  The provisions of this Section 6 will remain in full force and
effect, regardless of any investigation made by or on behalf of any Purchaser,
any other Holder, the Company or any underwriter or any of the officers,
directors or controlling persons referred to in this Section 6, and will survive
the sale by a Holder of securities covered by a Registration Statement.

          7.   Miscellaneous.
               -------------

          (a)  No Inconsistent Agreements.  The Company has not, as of the date
               ---------------------------
hereof, entered into, nor shall it, on or after the date hereof, enter into, any
agreement with respect to its securities that limits the rights granted to the
Holders herein or otherwise conflicts with the provisions hereof.

          (b)  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 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
Purchaser hereunder, the Company shall obtain the written consent of each such
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 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

Each broker-dealer that receives New Securities for its own account pursuant to
the Registered 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 New 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 hereof
(the "Expiration Date") and ending on the close of business on the day that is
180 days following the Expiration Date, it will make this Prospectus available
to any broker-dealer for use in connection with any such resale.  See "Plan of
Distribution."

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 Registered Exchange Offer must acknowledge that it will deliver
a prospectus in connection with any resale of such New Securities.  The
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.  The Company has agreed
that, starting on the Expiration Date and ending on the close of business on the
day that is 180 days following the Expiration Date, it will make this
Prospectus, as amended or supplemented, available to any broker-dealer for use
in connection with any such resale.  In addition, until             , 2000, all
dealers effecting transactions in the Exchange Securities may be required to

       The Company will not receive any proceeds from any sale of New Securities
by broker-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 Registered 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 of 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, the Company 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.  The Company has agreed to pay all expenses
incident to the Exchange Offer (other than the expenses of 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.
