               (ii)   keep the Exchange Offer open for acceptance for a 
period of not less than 20 business days after the date notice thereof is

               (v)    notify each Holder that any Registrable Security not

laws relating to the Exchange Offer.
          (c)  If, prior to consummation of the Exchange Offer, the Initial

unsold allotment in the initial distribution, the Issuer upon the request of 
any Initial Purchaser shall, simultaneously with the delivery of the Exchange 
Securities in the Exchange Offer, issue and deliver to such Initial 
Purchaser, in exchange (the "PRIVATE EXCHANGE") for the Securities held by 
such Initial Purchaser, a like principal amount of debt securities of the 
Issuer on a senior basis, that are identical (except that such securities 
shall bear appropriate transfer restrictions) to the Exchange Securities (the 
"PRIVATE EXCHANGE SECURITIES").
          (d)  The Exchange Securities and the Private Exchange Securities 
shall be issued under (i) the Indenture or (ii) an indenture identical in all 
material respects to the Indenture and which, in either case, has been 
qualified under the Trust Indenture Act of 1939, as amended (the "TIA"), or 
is exempt from such qualification and shall provide that the Exchange 
Securities shall not be subject to the transfer restrictions set forth in the 
Indenture but that the Private Exchange Securities shall be subject to such 
transfer restrictions.  The Indenture or such indenture shall provide that 
the Exchange Securities, the Private Exchange Securities and the Securities 
shall vote and consent together on all matters as one class and that none of 
the Exchange Securities, the Private Exchange 
                                      -8-
Securities or the Securities will have the right to vote or consent as a 
separate class on any matter.  The Private Exchange Securities shall be of 
the same series as the Exchange Securities and the Issuer shall use all 
commercially reasonable efforts to have the Private Exchange Securities bear 
the same CUSIP number as the Exchange Securities.  The Issuer shall not have 
any liability under this Agreement solely as a result of such Private 
Exchange Securities not bearing the same CUSIP number as the Exchange 
Securities.
          (e)  As soon as practicable after the close of the Exchange Offer 
and/or the Private Exchange, as the case may be (to the extent not prohibited 
by any applicable law or applicable interpretation of the staff of the SEC),

     tendered and not validly withdrawn pursuant to the Exchange Offer in
     accordance with the terms of the Exchange Offer Registration Statement and
     the letter of transmittal which shall be an exhibit thereto;
               (ii)   accept for exchange all Securities duly tendered pursuant
     to the Private Exchange;
               (iii)  deliver to the Trustee for cancellation all Registrable
     Securities so accepted for exchange; and
               (iv)   cause the Trustee promptly to authenticate and deliver
     Exchange Securities or Private Exchange Securities, as the case may be, to
     each Holder of Registrable Securities so accepted for exchange in a
     principal amount equal to the principal amount of the Registrable
     Securities of such Holder so accepted for exchange.
          (f)  Interest on each Exchange Security and Private Exchange 
Security will accrue from the last date on which interest was paid on the 
Registrable Securities surrendered in exchange therefor or, if no interest 
has been paid on the Registrable Securities, from the date of original 
issuance.  The Exchange Offer and the Private Exchange shall not be subject 
to any conditions, other than (i) that the Exchange Offer or the Private 
Exchange, or the making of any exchange by a Holder, does not violate 
applicable law or any applicable interpretation of the staff of the SEC, (ii) 
the due tendering of Registrable Securities in accordance with the Exchange 
Offer and the Private Exchange, (iii) that each Holder of Registrable 
Securities exchanged in the Exchange Offer shall have represented that it is

and prospectus delivery requirements of the 1933 Act to the extent

acquired in the ordinary course of its business and that at the time of the 
consummation of the Exchange Offer it shall have no arrangement or 
understanding with any Person to participate in the distribution (within the 
meaning of the ▇▇▇▇ ▇▇▇) of the Exchange Securities and shall have made such 
other representations as may be reasonably necessary under applicable SEC 
rules, regulations or interpretations to render the use of Form S-4 or other 
appropriate form under the 1933 Act available, (iv) that no action or 
proceeding shall have been instituted or threatened in any court or by or 
before any governmental agency with respect to the Exchange Offer or the 
Private Exchange which, in the Issuer's judgment, would reasonably be 
expected to impair the ability of the Issuer to proceed with the Exchange 
Offer or the Private Exchange and (v) compliance with Section 3(f) hereof.  
To the extent permitted by law and ascertainable by the Issuer, the Issuer

     permitted by current interpretations by the SEC 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 Section 
     solely with respect to broker-dealers who acquired their Securities as a 
     result of market making or other trading activities, 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.  In the event that the Issuer is required to file 
     a Shelf Registration Statement upon the request of any Holder (including 
     an Initial Purchaser) not eligible pursuant to clause (iii) or (iv) above 
     to participate in the Exchange Offer, the Issuer shall file and use its 
     best efforts to have declared effective by the SEC both an Exchange Offer 
     Registration Statement pursuant to Section 2.1 with respect to all 
     Registrable Securities and a Shelf Registration Statement (which may be a
     combined Registration Statement with the Exchange Offer Registration
     Statement) with respect to offers and sales of Registrable Securities held
     by such Holder or such Initial Purchaser, as applicable, after completion
     of the Exchange Offer.
               (y)    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 SEC, or
     for such shorter period that will terminate when all Registrable Securities
     covered by the Shelf Registration Statement have been sold pursuant to the
     Shelf Registration Statement or cease to be outstanding or otherwise to be
     Registrable Securities (the "EFFECTIVENESS PERIOD"); PROVIDED, HOWEVER,
     that the Effectiveness Period in respect of the Shelf Registration
     Statement shall be extended to the extent required to permit dealers to
     comply with the applicable prospectus delivery requirements of Rule 174
     under the 1933 Act and as otherwise provided herein; and
               (z)    Notwithstanding any other provisions hereof, use its best
     efforts to ensure that (i) any Shelf Registration Statement and any
     amendment thereto and any Prospectus forming part thereof and any
     supplement thereto complies in all material respects with the 1933 Act and
     the rules and regulations thereunder, (ii) any Shelf Registration Statement
     and any amendment thereto does 
                                      -11-
     not, when it becomes effective, contain an untrue statement of a material 
     fact or omit to state a material fact required to be stated therein or 
     necessary to make the statements therein not misleading and (iii) any 
     Prospectus forming part of any Shelf Registration Statement, and any 
     supplement to such Prospectus (as amended or supplemented from time to 
     time), does not include an untrue statement of a material fact or omit to 
     state a material fact necessary in order to make the statements, in light 
     of the circumstances under which they were made, not misleading.
          The Issuer shall not permit any securities other than Registrable 
Securities to be included in the Shelf Registration Statement.  The Issuer 
further agrees, if necessary, to supplement or amend the Shelf Registration 
Statement, as required by Section 3(b) below, and to furnish to the Holders 
of Registrable Securities included in such Shelf Registration Statement 
copies of any such supplement or amendment promptly after its being used or 
filed with the SEC.
          2.3  EXPENSES.  The Issuer shall pay all Registration Expenses in 
connection with the registration pursuant to Section 2.1 or 2.2.  Each Holder 
shall pay all underwriting discounts and commissions and transfer taxes, if 
any, relating to the sale or disposition of such Holder's Registrable 
Securities pursuant to the Shelf Registration Statement and the fees and 
expenses of counsel other than the one counsel set forth in the definition of 
Registration Expenses.
          2.4  EFFECTIVENESS. 
               (a)    The Issuer will be deemed not to have used its best 
efforts to cause the Exchange Offer Registration Statement or the Shelf 
Registration Statement, as the case may be, to become, or to remain, 
effective during the requisite period if the Issuer voluntarily takes any 
action that would, or omits to take any action which omission would, result 
in any such Registration Statement not being declared effective or in the 
Holders of Registrable Securities covered thereby not being able to exchange 
or offer and sell such Registrable Securities during that period as and to 
the extent contemplated hereby, unless (i) such action is required by 
applicable law or (ii) such action is taken by the Issuer in good faith 
pursuant to Section 2.4(c).
               (b)    An Exchange Offer Registration Statement pursuant to 
Section 2.1 hereof or a Shelf Registration Statement pursuant to Section 2.2 
hereof will not be deemed to have become effective unless it has been 
declared effective by the SEC; PROVIDED, HOWEVER, that if, after it has been 
declared effective, the offering of Registrable Securities pursuant to an 
Exchange Offer Registration Statement or a Shelf Registration Statement is 
interfered with by any stop order, injunction or other order or requirement 
of the SEC or any other governmental agency or court, such Registration 
Statement will be 
                                     -12-
deemed not to be effective during the period of such interference, until the 
offering of Registrable Securities pursuant to such Registration Statement 
may legally resume.
               (c)    During any 365-day period, the Issuer may suspend the 
availability of a Shelf Registration Statement and the use of the related 
Prospectus, for up to two periods of up to 45 consecutive days each (except 
for the consecutive 45-day period immediately prior to maturity of the 
Security), but no more than an aggregate of 60 days during any 365-day 
period, if any event shall occur as a result of which it shall be necessary, 
in the good faith determination of the board of directors of the Issuer, to 
amend the Shelf Registration Statement or amend or supplement any Prospectus 
or prospectus supplement thereunder in order that each such document not 
include any untrue statement of material fact or omit to state a material 
fact necessary to make the statements therein not misleading in light of the 
circumstances under which they were made.
          2.5  INTEREST. (a)  The Indenture provides that in the event that 
either (i) the Exchange Offer Registration Statement is not filed with the 
SEC on or prior to the 120th calendar day after the date of this Agreement, 
(ii) the Exchange Offer Registration Statement has not been declared 
effective on or prior to the 180th calendar day after the date of this 
Agreement, (iii) the Exchange Offer is not consummated or, if required, a 
Shelf Registration Statement is not declared effective, in either case, on or 
prior to the 215th calendar day after the date of this Agreement or (iv) the 
Exchange Offer Registration Statement is declared effective but thereafter 
ceases to be effective or usable (each such event referred to in clauses (i) 
through (iv) above, a "REGISTRATION DEFAULT"), the interest rate borne by the 
Securities shall be increased ("ADDITIONAL INTEREST") by one-half of one 
percent (0.50%) per annum upon the occurrence of each Registration Default, 
which rate will increase by one half of one percent each 90-day period that 
such Additional Interest continues to accrue under any such circumstance; 
PROVIDED that the maximum aggregate increase in the interest rate will in no 
event exceed one percent (1%) per annum.  Upon (w) the filing of the Exchange 
Offer Registration Statement after the 120-day period described in clause (i) 
above, (x) the effectiveness of the Exchange Offer Registration Statement 
after the 180-day period described in clause (ii) above, (y) the consummation 
of the Exchange Offer or the effectiveness of a Shelf Registration Statement, 
as the case may be, after the 215-day period described in clause (iii) above, 
or (z) the cure of any Registration Default described in clause (iv) above, 
such additional interest shall cease to accrue from the date of such filing, 
effectiveness, consummation or cure, as the case may be, if the Issuer is 
otherwise in compliance with this section; provided, however, that if, after 
any such Additional Interest ceases to accrue, a different event specified in 
clause (i), (ii), (iii) or (iv) above occurs, such Additional Interest will 
again accrue pursuant to the foregoing provision.
                                     -13-
          (b)  The Issuer shall notify the Trustee within five business days 
after each and every date on which an event occurs in respect of which 
Additional Interest is required to be paid (an "EVENT DATE").  Additional 
Interest shall be paid by depositing with the Trustee, in trust, for the 
benefit of the Holders of Registrable Securities before the applicable 
semiannual interest payment date, immediately available funds in sums 
sufficient to pay the Additional Interest then due.  The Additional Interest 
due shall be payable on each interest payment date to the record holder of 
Securities entitled to receive the interest payment to be paid on such date 
as set forth in the Indenture.  Each obligation to pay Additional Interest 
shall be deemed to accrue from and including the day following the applicable 
Event Date.
          3.   REGISTRATION PROCEDURES.
          In connection with the obligations of the Issuer with respect to 
Registration Statements pursuant to Sections 2.1 and 2.2 hereof, the Issuer 
shall:
          (a)  prepare and file with the SEC a Registration Statement, within 
the relevant time period specified in Section 2, on the appropriate form 
under the 1933 Act, which form (i) shall be selected by the Issuer, (ii) 
shall, in the case of a Shelf Registration, be available for the sale of the 
Registrable Securities by the selling Holders thereof, (iii) shall comply as 
to form in all material respects with the requirements of the applicable form 
and include or incorporate by reference all financial statements required by 
the SEC to be filed therewith or incorporated by reference therein, and (iv) 
shall comply in all respects with the requirements of Regulation S-T under 
the 1933 Act, and use its best efforts to cause such Registration Statement 
to become effective and remain effective in accordance with Section 2 hereof;
          (b)  prepare and file with the SEC such amendments and 
post-effective amendments to each Registration Statement as may be necessary 
under applicable law to keep such Registration Statement effective for the 
applicable period; and cause each Prospectus to be supplemented by any 
required prospectus supplement, and as so supplemented to be filed pursuant 
to Rule 424 (or any similar provision then in force) under the 1933 Act and 
comply with the provisions of the 1933 Act, the 1934 Act and the rules and 
regulations thereunder applicable to them with respect to the disposition of 
all securities covered by each Registration Statement during the applicable 
period in accordance with the intended method or methods of distribution by 
the selling Holders thereof (including sales by any Participating 
Broker-Dealer);
          (c)  in the case of a Shelf Registration, (i) notify each Holder of 
Registrable Securities, at least five business days prior to filing, that a 
Shelf Registration Statement with respect to the Registrable Securities is 
being filed and advising such Holders that the distribution of Registrable 
Securities will be made in accordance with the 
                                     -14-
method selected by the Majority Holders participating in the Shelf 
Registration; (ii) furnish to each Holder of Registrable Securities included 
in the Shelf Registration Statement and to each underwriter of an 
underwritten offering of Registrable Securities included in the Shelf 
Registration Statement, if any, without charge, as many copies of each 
Prospectus, including each preliminary Prospectus, and any amendment or 
supplement thereto and such other documents as such Holder or underwriter may 
reasonably request, including financial statements and schedules and, if the 
Holder so requests, all exhibits in order to facilitate the public sale or 
other disposition of the Registrable Securities included in the Shelf 
Registration Statement; and (iii) subject to the third from the last 
paragraph of this Section 3, hereby consent to the use of the Prospectus or 
any amendment or supplement thereto by each of the selling Holders of 
Registrable Securities included in the Shelf Registration Statement in 
connection with the offering and sale of the Registrable Securities covered 
by the Prospectus or any amendment or supplement thereto;
          (d)  use its best efforts to register or qualify the Registrable 
Securities under all applicable state securities or "blue sky" laws of such 
jurisdictions as any Holder of Registrable Securities covered by a 
Registration Statement and each underwriter of an underwritten offering of 
Registrable Securities shall reasonably request by the time the applicable 
Registration Statement is declared effective by the SEC, and do any and all 
other acts and things which may be reasonably necessary or advisable to 
enable each such Holder and underwriter to consummate the disposition in each 
such jurisdiction of such Registrable Securities owned by such Holder; 
PROVIDED, HOWEVER, that the Issuer shall not be required to (i) qualify as a 
foreign corporation or as a dealer in securities in any jurisdiction where it 
would not otherwise be required to qualify but for this Section 3(d), or (ii) 
take any action which would subject it to general service of process or 
taxation in any such jurisdiction where it is not then so subject;
          (e)  if, following the date hereof there has been announced a 
change in SEC policy with respect to exchange offers such as the Exchange 
Offer, that in the reasonable opinion of counsel to the Issuer raises a 
substantial question as to whether the Exchange Offer is permitted by 
applicable federal law, the Issuer hereby agrees to seek a no-action letter 
or other favorable decision from the SEC allowing the Issuer to consummate an 
Exchange Offer for Registrable Securities contemplated hereby.  The Issuer 
hereby agrees to pursue the issuance of such a decision to the SEC staff 
level.  In connection with and subject to the foregoing, the Issuer hereby 
agrees to take all such other actions as may be reasonably requested by the 
SEC or otherwise required in connection with the issuance of such decision, 
including, without limitation, (A) participating in telephonic conferences 
with the SEC, (B) delivering to the SEC staff an analysis prepared by counsel 
to the Issuer setting forth the legal bases, if any, upon which such counsel 
has concluded that such an Exchange Offer should be permitted and (C) 
diligently pursuing a resolution (which need not be favorable) by the SEC 
staff;
                                      -15-
          (f)  as a condition to its participation in the Exchange Offer, 
each Holder of Registrable Securities (including, without limitation, any 
Holder who is a Participating Broker-Dealer) shall furnish, upon the request 
of the Issuer, prior to the consummation of the Exchange Offer, a written 
representation to the Issuer (which may be contained in the letter of 
transmittal contemplated by the Exchange Offer Registration Statement) to the 
effect that (A) it is not an affiliate of the Issuer, (B) it is not engaged 
in, and does not intend to engage in, and has no arrangement or understanding 
with any person to participate in, a distribution of the Exchange Securities 
to be issued in the Exchange Offer and (C) it is acquiring the Exchange 
Securities in its ordinary course of business. In addition, all such Holders 
of Registrable Securities shall otherwise reasonably cooperate to the extent 
necessary in the Issuer's preparations for the Exchange Offer.  Each Holder 
using the Exchange Offer to participate in a distribution of the Exchange 
Securities hereby acknowledges and agrees that, if the resales are of 
Exchange Securities obtained by such Holder in exchange for Securities 
acquired directly from the Issuer or an affiliate thereof, it (1) could not, 
under SEC policy as in effect on the date of this Agreement, rely on the 
position of the SEC enunciated in ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ AND CO., INC. (available 
June 5, 1991) and EXXON CAPITAL HOLDINGS CORPORATION (available May 13, 
1988), as interpreted in the SEC's letter to SHEARMAN & STERLING dated July 
2, 1993, and similar no-action letters (including, if applicable, any 
no-action letter obtained pursuant to clause (e) above), and (2) must comply 
with the registration and prospectus delivery requirements of the 1933 Act in 
connection with a secondary resale transaction and that such a secondary 
resale transaction 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;
          (g)  prior to effectiveness of the Exchange Offer Registration 
Statement, the Issuer shall, to the extent requested or required by the SEC, 
provide a supplemental letter to the SEC (A) stating that the Issuer is 
registering the Exchange Offer in reliance on the position of the SEC 
enunciated in EXXON CAPITAL HOLDINGS CORPORATION (available May 13, 1988), 
and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ AND CO., INC. (available June 5, 1991) as interpreted in 
the SEC's letter to SHEARMAN & STERLING dated July 2, 1993, and, if 
applicable, any no-action letter obtained pursuant to clause (e) above, (B) 
including a representation that  the Issuer has not entered into any 
arrangement or understanding with any Person to distribute the Exchange 
Securities to be received in the Exchange Offer, and to the extent that the 
Issuer is capable of so representing, to the best of the Issuer's information 
and belief, each Holder participating in the Exchange Offer is acquiring the 
Exchange Securities in its ordinary course of business and has no arrangement 
or understanding with any Person to participate in the distribution of the 
Exchange Securities received in the Exchange Offer and (C) any other 
undertaking or representation required by the SEC as set forth in any 
no-action letter obtained pursuant to clause (e) above, if applicable;
                                      -16-
          (h)  notify promptly each Holder of Registrable Securities included 
in a Shelf Registration or any Participating Broker-Dealer who has notified 
the Issuer that it is utilizing the Exchange Offer Registration Statement as 
provided in paragraph (f) above and, if requested by such Holder or 
Participating Broker-Dealer, confirm such advice in writing promptly (i) when 
a Registration Statement has become effective and when any post-effective 
amendments and supplements thereto become effective, (ii) of any request by 
the SEC or any state securities authority for post-effective amendments and 
supplements to a Registration Statement and Prospectus or for additional 
information after the Registration Statement has become effective, (iii) of 
the issuance by the SEC or any state securities authority of any stop order 
suspending the effectiveness of a Registration Statement or the initiation of 
any proceedings for that purpose, (iv) in the case of a Shelf Registration, 
if, between the effective date of a Registration Statement and the closing of 
any sale of Registrable Securities covered thereby, the representations and 
warranties of the Issuer contained in any underwriting agreement, securities 
sales agreement or other similar agreement, if any, relating to the offering 
cease to be true and correct in all material respects, (v) of the happening 
of any event or the discovery of any facts during the period a Shelf 
Registration Statement is effective which makes any statement made in such 
Registration Statement or the related Prospectus untrue in any material 
respect or which requires the making of any changes in such Registration 
Statement or Prospectus in order to make the statements therein not 
misleading, (vi) of the receipt by the Issuer of any notification with 
respect to the suspension of the qualification of the Registrable Securities 
or the Exchange Securities, as the case may be, included in the Registration 
Statement for sale in any jurisdiction or the initiation or threatening of 
any proceeding for such purpose and (vii) of any determination by the Issuer 
that a post-effective amendment to such Registration Statement would be 
appropriate;
          (i)  in the case of the Exchange Offer Registration Statement (i) 
include in the Exchange Offer Registration Statement a section entitled "Plan 
of Distribution" which section shall be reasonably acceptable to ▇▇▇▇▇▇▇ 
▇▇▇▇▇ on behalf of the Participating Broker-Dealers, and which shall contain 
a summary statement of the positions taken or policies made by the staff of 
the SEC with respect to the potential "underwriter" status of any 
broker-dealer that holds Registrable Securities acquired for its own account 
as a result of market-making activities or other trading activities and that 
will be the beneficial owner (as defined in Rule l3d-3 under the ▇▇▇▇ ▇▇▇) of 
Exchange Securities to be received by such broker-dealer in the Exchange 
Offer, whether such positions or policies have been publicly disseminated by 
the staff of the SEC or such positions or policies, in the reasonable 
judgment of ▇▇▇▇▇▇▇ ▇▇▇▇▇, on behalf of the Participating Broker-Dealers, and 
its counsel, represent the prevailing views of the staff of the SEC, 
including a statement that any such broker-dealer who receives Exchange 
Securities for Registrable Securities pursuant to the Exchange Offer may be 
deemed a statutory underwriter and must deliver a prospectus meeting the 
requirements of the 1933 
                                      -17-
Act in connection with any resale of such Exchange Securities, (ii) furnish 
to each Participating Broker-Dealer who has delivered to the Issuer the 
notice referred to in Section 2.2(iii)(c), without charge, as many copies of 
each Prospectus included in the Exchange Offer Registration Statement, 
including any preliminary prospectus, and any amendment or supplement 
thereto, as such Participating Broker-Dealer may reasonably request, (iii) 
hereby consent to the use of the Prospectus forming part of the Exchange 
Offer Registration Statement or any amendment or supplement thereto, by any 
Person subject to the prospectus delivery requirements of the SEC, including 
all Participating Broker-Dealers, in connection with the sale or transfer of 
the Exchange Securities covered by the Prospectus or any amendment or 
supplement thereto, and (iv) include in the transmittal letter or similar 
documentation to be executed by an exchange offeree in order to participate 
in the Exchange Offer (x) the following provision:
     "If the exchange offeree is not a broker-dealer, it hereby represents
     that it is not engaged in, and does not intend to engage in, the
     distribution of the Exchange Securities.  If the exchange offeree is a
     broker-dealer that will receive Exchange Securities for its own
     account in exchange for Securities that were acquired as a result of
     market-making activities or other trading activities, it will deliver
     a prospectus meeting the requirements of the 1933 Act in connection
     with any resale of Exchange Securities received in respect of such
     Securities pursuant to the Exchange Offer;" and
(y) a statement to the effect that by a broker-dealer making the 
acknowledgment described in clause (x) and by delivering a Prospectus in 
connection with the exchange of Registrable Securities, the broker-dealer 
will not be deemed to admit that it is an underwriter within the meaning of 
the 1933 Act;
          (j)  to the extent any Participating Broker-Dealer participates in 
the Exchange Offer, the Issuer agrees to deliver to the Initial Purchasers on 
behalf of the Participating Broker-Dealers upon the effectiveness of the 
Exchange Offer Registration Statement, (i) officers' certificates 
substantially in the form customarily delivered in a public offering of debt 
securities and (ii) a comfort letter or comfort letters in customary form to 
the extent permitted by Statement on Auditing Standards No. 72 of the 
American Institute of Certified Public Accountants (or if such a comfort 
letter is not permitted, an agreed upon procedures letter in customary form) 
from the Issuer's independent certified public accountants (and, if 
necessary, any other independent certified public accountants of any 
subsidiary of the Issuer or of any business acquired by the Issuer for which 
financial statements are, or are required to be, included in the Registration 
Statement) at least as broad in scope and coverage as the comfort letter or 
comfort letters delivered to 
                                     -18-
the Initial Purchasers in connection with the initial sale of the Securities 
to the Initial Purchasers;
          (k)  (i) in the case of an Exchange Offer, furnish counsel for the 
Initial Purchasers and (ii) in the case of a Shelf Registration, furnish 
counsel for the Holders of Registrable Securities, copies of any comment 
letters received from the SEC or any other request by the SEC or any state 
securities authority for amendments or supplements to a Registration 
Statement and Prospectus or for additional information;
          (l)  make every reasonable effort to obtain the withdrawal of any 
order suspending the effectiveness of a Registration Statement at the 
earliest possible moment;
          (m)  in the case of a Shelf Registration, furnish to each Holder of 
Registrable Securities included therein, and each underwriter, if any, 
without charge, at least one conformed copy of each Registration Statement 
and any post-effective amendment thereto, including financial statements and 
schedules (without documents incorporated therein by reference and all 
exhibits thereto, unless requested);
          (n)  in the case of a Shelf Registration, cooperate with the 
selling Holders of Registrable Securities included therein to facilitate the 
timely preparation and delivery of certificates representing Registrable 
Securities to be sold and not bearing any restrictive legends; and enable 
such Registrable Securities to be in such denominations (consistent with the 
provisions of the Indenture) and registered in such names as the selling 
Holders or the underwriters, if any, may reasonably request at least three 
business days prior to the closing of any sale of Registrable Securities;
          (o)  in the case of a Shelf Registration, upon the occurrence of 
any event or the discovery of any facts, each as contemplated by Sections 
3(h)(v) and 3(h)(vi) hereof, as promptly as practicable after the occurrence 
of such an event, use its best efforts to prepare a supplement or 
post-effective amendment to the Registration Statement or the related 
Prospectus or any document incorporated therein by reference or file any 
other required document so that, as thereafter delivered to the purchasers of 
the Registrable Securities included therein or by Participating 
Broker-Dealers, such Prospectus will not contain at the time of such delivery 
any untrue statement of a material fact or omit to state a material fact 
necessary to make the statements therein, in light of the circumstances under 
which they were made, not misleading.  At such time as such public disclosure 
is otherwise made or the Issuer determines that such disclosure is not 
necessary, in each case to correct any misstatement of a material fact or to 
include any omitted material fact, the Issuer agrees promptly to notify each 
such Holder of such determination and to furnish each such Holder such number 
of copies of the Prospectus as amended or supplemented, as such Holder may 
reasonably request;
                                     -19-
          (p)  in the case of a Shelf Registration, a reasonable time prior to
the filing of any Registration Statement, any Prospectus, any amendment to a
Registration Statement or amendment or supplement to a Prospectus or any
document which is to be incorporated by reference into a Registration Statement
or a Prospectus after initial filing of a Registration Statement, provide copies
of such document to the Initial Purchasers on behalf of the Holders whose
Registrable Securities are included therein; and make such representatives of
the Issuer as shall be reasonably requested by the Holders of Registrable
Securities included therein, or the Initial Purchasers, on behalf of such
Holders, available for discussion of such document;
          (q)  obtain a CUSIP number for all Exchange Securities, Private
Exchange Securities or Securities, as the case may be, not later than the
effective date of a Registration Statement, and provide the Trustee with printed
certificates for the Exchange Securities, Private Exchange Securities or the
Securities, as the case may be, in a form eligible for deposit with the
Depositary;
          (r)  (i) cause the Indenture to be qualified under the TIA in
connection with the registration of the Exchange Securities or Registrable
Securities, as the case may be, (ii) cooperate with the Trustee and the Holders
to effect such changes to the Indenture as may be required for the Indenture to
be so qualified in accordance with the terms of the TIA and (iii) execute, and
use its best efforts to cause the Trustee to execute, all documents as may be
required to effect such changes, and all other forms and documents required to
be filed with the SEC to enable the Indenture to be so qualified in a timely
manner;
          (s)  in the case of a Shelf Registration, enter into agreements
(including underwriting agreements) and take all other customary and appropriate
actions in order to expedite or facilitate the disposition of the Registrable
Securities included therein and in such connection whether or not an
underwriting agreement is entered into and whether or not the registration is an
underwritten registration:
               (i)    make such representations and warranties to the Holders of
     the Registrable Securities included therein and the underwriters, if any,
     in form, substance and scope as are customarily made by issuers to
     underwriters in similar underwritten offerings as may be reasonably
     requested by them;
               (ii)   obtain opinions of counsel to the Issuer and updates
     thereof (which counsel and opinions (in form, scope and substance) shall be
     reasonably satisfactory to the managing underwriters, if any, and the
     holders of a majority in principal amount of the Registrable Securities
     being sold) addressed to each selling Holder and the underwriters, if any,
     covering the matters customarily covered in opinions requested in sales of
     securities or underwritten offerings and 
                                    -20-

     underwriters;
               (iii)  obtain "cold comfort" letters and updates thereof from the

     Issuer or of any business acquired by the Issuer for which financial
     statements are, or are required to be, included in the Registration
     Statement) addressed to the underwriters, if any, and use reasonable
     efforts to have such letter addressed to the selling Holders of Registrable
     Securities (to the extent consistent with Statement on Auditing Standards
     No. 72 of the American Institute of Certified Public Accounts), such

     things, the appointment of such agent for the selling Holders for the
     purpose of soliciting purchases of Registrable Securities included therein,
     which agreement shall be in form, substance and scope customary for similar
     offerings;
               (v)    if an underwriting agreement is entered into, cause the
     same to set forth indemnification provisions and procedures substantially
     equivalent to the indemnification provisions and procedures set forth in
     Section 4 hereof with respect to the underwriters and all other parties to
     be indemnified pursuant to said Section or, at the request of any
     underwriters, in the form customarily provided to such underwriters in
     similar types of transactions; and
               (vi)   deliver such documents and certificates as may be
     reasonably requested and as are customarily delivered in similar offerings
     to the Holders of a majority in principal amount of the Registrable
     Securities being sold and the managing underwriters, if any.

(and each post-effective amendment thereto) and (ii) each closing under any
underwriting or similar agreement as and to the extent required thereunder;
          (t)  in the case of a Shelf Registration, or in the case of an
Exchange Offer, if a Prospectus is required to be delivered by any Participating

of the Registrable Securities included therein, any underwriters participating
in any disposition pursuant to a Shelf Registration Statement, any such
Participating Broker-Dealer and any counsel or

pertinent corporate documents and properties of the Issuer reasonably 
requested by any such persons, and cause the respective officers, directors, 
employees, and any other agents of the Issuer to supply all information 
reasonably requested by any such representative, underwriter, special counsel 
or accountant in connection with a Registration Statement, and make such 
representatives of the Issuer available for discussion of such documents as 
shall be reasonably requested by the Initial Purchasers; provided that any 
such records, documents, properties and such information that is designated 
in writing by the Issuer, in good faith, as confidential at the time of 
delivery of such records, documents, properties or information shall be kept 
confidential by any such representative, underwriter, special counsel or 
accountant and shall be used only in connection with such Shelf Registration 
Statement, unless disclosure thereof is made in connection with a court 
proceeding or required by  law, or such information has become available (not 
in violation of this Agreement) to the public generally or through a third 
party without an accompanying obligation of confidentiality, and the Issuer 
shall be entitled to request that such representative, underwriter, special 
counsel or accountant sign a confidentiality agreement to the foregoing 
effect;
          (u)  (i) in the case of an Exchange Offer Registration Statement, a
reasonable time prior to the filing of any Exchange Offer Registration
Statement, any Prospectus forming a part thereof, any amendment to an Exchange
Offer Registration Statement or amendment or supplement to such Prospectus,
provide copies of such document to the Initial Purchasers and to counsel to the
Holders of Registrable Securities and make such changes in any such document
prior to the filing thereof as the Initial Purchasers or counsel to the Holders
of Registrable Securities may reasonably request and, except as otherwise
required by applicable law, not file any such document in a form to which the
Initial Purchasers on behalf of the Holders of Registrable Securities and
counsel to such Holders of Registrable Securities shall not have previously been
advised and furnished a copy of or to which the Initial Purchasers on behalf of
the Holders of Registrable Securities or counsel to the Holders of Registrable
Securities shall reasonably object, and make the representatives of the Issuer
available for discussion of such documents as shall be reasonably requested by
the Initial Purchasers, and
               (ii)   in the case of a Shelf Registration, a reasonable time
prior to filing any Shelf Registration Statement, any Prospectus forming a part
thereof, any amendment to such Shelf Registration Statement or amendment or
supplement to such Prospectus, provide copies of such document to the Holders of
Registrable Securities included or to be included in such Shelf Registration, to
the Initial Purchasers, to counsel for such Holders and to the underwriter or
underwriters of an underwritten offering of Registrable Securities, if any, make
such changes in any such document prior to the filing thereof as the Initial
Purchasers, the counsel to such Holders or the underwriter or underwriters
reasonably request and not file any such document in a form to which the
                                    -22-
Majority Holders, the Initial Purchasers on behalf of such Holders of
Registrable Securities, counsel for the Holders of Registrable Securities or any
underwriter shall not have previously been advised and furnished a copy of or to
which the Majority Holders, the Initial Purchasers of behalf of such Holders of
Registrable Securities, counsel to such Holders of Registrable Securities or any
underwriter shall reasonably object, and make the representatives of the Issuer
available for discussion of such document as shall be reasonably requested by
such Holders of Registrable Securities, the Initial Purchasers on behalf of such
Holders, counsel for such Holders of Registrable Securities or any underwriter;
          (v)  in the case of a Shelf Registration, use its best efforts to
cause all Registrable Securities included therein to be listed on any securities
exchange on which similar debt securities issued by the Issuer are then listed
if requested by the Majority Holders whose securities are included therein, or
if requested by the underwriter or underwriters of an underwritten offering of
Registrable Securities, if any;
          (w)  in the case of a Shelf Registration, use its best efforts to
cause the Registrable Securities included therein to be rated by the appropriate
rating agencies, if so requested by the Majority Holders whose securities are
included therein, or if requested by the underwriter or underwriters of an
underwritten offering of Registrable Securities included therein, if any;
          (x)  otherwise comply with all applicable rules and regulations of the
SEC and make available to its security holders, as soon as reasonably
practicable, an earnings statement covering at least 12 months which shall
satisfy the provisions of Section 11(a) of the 1933 Act and Rule 158 thereunder;
and
          (y)  cooperate and assist in any filings required to be made with the
NASD and, in the case of a Shelf Registration, in the performance of any due
diligence investigation by any underwriter and its counsel (including any
"qualified independent underwriter" that is required to be retained in
accordance with the rules and regulations of the NASD).
          In the case of a Shelf Registration Statement, the Issuer may (as a
condition to such Holder's participation in the Shelf Registration) require each
Holder of Registrable Securities to furnish to the Issuer such information
regarding the Holder and the proposed distribution by such Holder of such
Registrable Securities as the Issuer may from time to time reasonably request in
writing.
          In the case of a Shelf Registration Statement, each Holder agrees
that, upon receipt of any notice from the Issuer of the happening of any event
or the discovery of any facts, each of the kind described in Section 3(h)(v) or
3(h)(vi) hereof, such Holder 
                                    -23-
will keep such information confidential and will forthwith discontinue 
disposition of Registrable Securities pursuant to a Registration Statement 
until such Holder's receipt of the copies of the supplemented or amended 
Prospectus contemplated by Section 3(o) hereof, and, if so directed by the 
Issuer, such Holder will deliver to the Issuer (at its expense) all copies in 
such Holder's possession, other than permanent file copies then in such 
Holder's possession, of all Prospectuses covering such Registrable Securities 
in effect at or prior to the time of receipt of such notice.
          In the event that the Issuer fails to effect the Exchange Offer or
file any Shelf Registration Statement and maintain the effectiveness of any
Shelf Registration Statement as provided herein, the Issuer shall not file any
Registration Statement with respect to any securities (within the meaning of
Section 2(l) of the ▇▇▇▇ ▇▇▇) of the Issuer other than Registrable Securities.
          If any of the Registrable Securities covered by any Shelf Registration
Statement are to be sold in an underwritten offering, the underwriter or
underwriters and manager or managers that will manage such offering will be
selected by the Majority Holders of such Registrable Securities included in such
offering and shall be acceptable to the Issuer.  No Holder of Registrable
Securities may participate in any underwritten registration hereunder unless
such Holder (a) agrees to sell such Holder's Registrable Securities on the basis
provided in any underwriting arrangements approved by the Persons entitled
hereunder to approve such arrangements and (b) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents required under the terms of such underwriting arrangements.
          4.   INDEMNIFICATION; CONTRIBUTION.
          (a)  The Issuer agrees to indemnify and hold harmless the Initial
Purchasers, each Holder, each Participating Broker-Dealer, each Person who
participates as an underwriter (any such Person being an "UNDERWRITER") and each
Person, if any, who controls any Holder or Underwriter within the meaning of
Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:
               (i)    against any and all losses, liabilities, claims, damages
     and expenses whatsoever, as incurred, arising out of any untrue statement
     or alleged untrue statement of a material fact contained in any
     Registration Statement (or any amendment or supplement thereto) pursuant to
     which Exchange Securities or Registrable Securities were registered under
     the 1933 Act, including all documents incorporated therein by reference, or
     the omission or alleged omission therefrom of a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading, or arising out of any untrue statement or alleged untrue
     statement of a material fact contained in any Prospectus (or any 
                                    -24-
     amendment or supplement thereto) or the omission or alleged omission 
     therefrom of a material fact necessary in order to make the statements 
     therein, in the light of the circumstances under which they were made, 
     not misleading;
               (ii)   against any and all losses, liabilities, claims, damages
     and expenses whatsoever, as incurred, to the extent of the aggregate amount
     paid in settlement of any litigation, or any investigation or proceeding by
     any governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission; PROVIDED that (subject to Section
     4(d) below) any such settlement is effected with the written consent of the
     Issuer; and
               (iii)  against any and all expenses whatsoever, as incurred
     (including the fees and disbursements of counsel chosen by any indemnified
     party), reasonably incurred in investigating, preparing or defending
     against any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, to the extent that any such expense
     is not paid under subparagraph (i) or (ii) above;
PROVIDED, HOWEVER, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense (A) to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Issuer by the
Holder or Underwriter expressly for use in a Registration Statement (or any
amendment thereto) or any Prospectus (or any amendment or supplement thereto),
(B) result from the use of the Prospectus during a period when the use of the
Prospectus has been suspended in accordance with Section 2.4(c); provided, in
each case, that Holders received reasonable prior notice of such suspension or
(c) result from the use of the Prospectus in violation of the third to last
paragraph of Section 3.
          (b)  Each Holder severally, but not jointly, agrees to indemnify and
hold harmless the Issuer, the Initial Purchasers, each Underwriter and the other
selling Holders, and each of their respective directors and officers, and each
Person, if any, who controls the Issuer, the Initial Purchasers, any
Underwriter or any other selling Holder within the meaning of Section 15 of the
1933 Act or Section 20 of the 1934 Act, against any and all loss, liability,
claim, damage and expense described in the indemnity contained in Section 4(a)
hereof, as incurred, but only with respect to untrue statements or omissions, or
alleged untrue statements or omissions, made in the Shelf Registration Statement
(or any amendment thereto) or any Prospectus included therein (or any amendment
or supplement thereto) in reliance upon and in conformity with written
information with respect to such Holder furnished to the Issuer by such Holder
expressly 
                                    -25-
for use in the Shelf Registration Statement (or any amendment thereto) or 
such Prospectus (or any amendment or supplement thereto); PROVIDED, HOWEVER, 
that no such Holder shall be liable for any claims hereunder in excess of the 
amount of net proceeds received by such Holder from the sale of Registrable 
Securities pursuant to such Shelf Registration Statement.
          (c)  Each indemnified party shall give notice in writing as promptly
as reasonably practicable to each indemnifying party of any action or proceeding
commenced against it in respect of which indemnity may be sought hereunder, but
failure so to notify an indemnifying party shall not relieve such indemnifying
party from any liability hereunder to the extent it is not materially prejudiced
as a result thereof and in any event shall not relieve it from any liability
which it may have otherwise than on account of this indemnity agreement.  An
indemnifying party may participate at its own expense in the defense of such
action; PROVIDED, HOWEVER, that counsel to the indemnifying party shall not
(except with the consent of the indemnified party) also be counsel to the
indemnified party.  In no event shall the indemnifying party or parties be
liable for the fees and expenses of more than one counsel (in addition to any
local counsel) separate from their own counsel for all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances.
No indemnifying party shall, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 4 (whether or not the indemnified parties are actual or
potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim and (ii) does
not include a statement as to or an admission of fault, culpability or a failure
to act by or on behalf of any indemnified party.
          (d)  If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 4(a)(ii) effected without its
written consent if (i) such settlement is entered into more than 45 days after
receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement.
          (e)  If the indemnification provided for in this Section 4 is for any
reason unavailable to or insufficient to hold harmless an indemnified party in
respect of 
                                    -26-
any losses, liabilities, claims, damages or expenses referred to therein, 
then each indemnifying party shall contribute to the aggregate amount of such 
losses, liabilities, claims, damages and expenses incurred by such 
indemnified party, as incurred, in such proportion as is appropriate to 
reflect the relative fault of the Issuer on the one hand and the Holders and 
the Initial Purchasers on the other hand in connection with the statements or 
omissions which resulted in such losses, liabilities, claims, damages or 
expenses, as well as any other relevant equitable considerations.
          The relative fault of the Issuer on the one hand and the Holders and
the Initial Purchasers on the other hand shall be determined by reference to,
among other things, whether any such untrue or alleged untrue statement of a
material fact or omission or alleged omission to state a material fact relates
to information supplied by the Issuer, the Holders or the Initial Purchasers and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.
          The Issuer, the Holders and the Initial Purchasers agree that it would
not be just and equitable if contribution pursuant to this Section 4 were
determined by pro rata allocation (even if the Initial Purchasers were treated
as one entity for such purpose) or by any other method of allocation which does
not take account of the equitable considerations referred to above in this
Section 4.  The aggregate amount of losses, liabilities, claims, damages and
expenses incurred by an indemnified party and referred to above in this Section
4 shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in investigating, preparing or defending against any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever based upon any such
untrue or alleged untrue statement or omission or alleged omission.
          Notwithstanding the provisions of this Section 4, no Initial Purchaser
shall be required to contribute any amount in excess of the amount by which the
total price at which the Securities sold by it were offered exceeds the amount
of any damages which such Initial Purchaser has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged
omission.
          No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any
Person who was not guilty of such fraudulent misrepresentation.
          For purposes of this Section 4, each Person, if any, who controls an
Initial Purchaser or Holder within the meaning of Section 15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same rights to contribution as such
Initial Purchaser or Holder, and each director of the Issuer, and each Person,
if any, who controls the Issuer within the meaning of Section 15 of the 1933 Act
or Section 20 of the 1934 Act shall 
                                    -27-
have the same rights to contribution as the Issuer.  The Initial Purchasers' 
respective obligations to contribute pursuant to this Section 4 are several 
in proportion to the principal amount of Securities set forth opposite their 
respective names in Schedule A to the Purchase Agreement and not joint.
          5.   MISCELLANEOUS.
          5.1  RULE 144 AND RULE 144A.  For so long as the Issuer is subject to
the reporting requirements of Section 13 or 15 of the 1934 Act, the Issuer
covenants that it will file the reports required to be filed by it under the
1933 Act and Section 13(a) or 15(d) of the 1934 Act and the rules and
regulations adopted by the SEC thereunder.  If the Issuer ceases to be so
required to file such reports, the Issuer covenants that it will upon the
request of any Holder of Registrable Securities (a) make publicly available such
information as is necessary to permit sales pursuant to Rule 144 under the 1933
Act, (b) deliver such information to a prospective purchaser as is necessary to
permit sales pursuant to Rule 144A under the 1933 Act and it will take such
further action as any Holder of Registrable Securities may reasonably request,
and (c) take such further action that is reasonable in the circumstances in each
case, to the extent required from time to time to enable such Holder to sell its
Registrable Securities without registration under the 1933 Act within the
limitation of the exemptions provided by (i) Rule 144 under the 1933 Act, as
such Rule may be amended from time to time, (ii) Rule 144A under the 1933 Act,
as such Rule may be amended from time to time, or (iii) any similar rules or
regulations hereafter adopted by the SEC.  Upon the request of any Holder of
Registrable Securities, the Issuer will deliver to such Holder a written
statement as to whether it has complied with such requirements.
          5.2  TERMINATION OF CERTAIN PARTIES' OBLIGATIONS UNDER THIS AGREEMENT.
Upon the consummation of the Combination, Telecommunications and the Partnership
will automatically, and without any further action by any person, be released
from their obligations under this Agreement.  In the event the offer to purchase
referred to in Section 10.21 of the Indenture is made and Securities remain
outstanding thereafter, the Company will automatically, and without any further
action by any person, be released from its obligations under this Agreement.
          5.3  NO INCONSISTENT AGREEMENTS.  The Issuer has not entered into and
the Issuer will not after the date of this Agreement enter into any agreement
which is inconsistent with the rights granted to the Holders of Registrable
Securities in this Agreement or otherwise conflicts with the provisions hereof. 
The rights granted to the Holders hereunder do not and will not for the term of
this Agreement in any way conflict with the rights granted to the holders of the
Issuer's other issued and outstanding securities under any such agreements.
                                    -28-
          5.4  AMENDMENTS AND WAIVERS.  The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Issuer has obtained the written consent of Holders
of at least a majority in aggregate principal amount of the outstanding
Registrable Securities affected by such amendment, modification, supplement,
waiver or departure.
          5.5  NOTICES.  All notices and other communications provided for or
permitted hereunder shall be made in writing by hand delivery, registered 
first-class mail, telex, telecopier, or any courier guaranteeing overnight 
delivery (a) if to a Holder, at the most current address given by such Holder 
to the Issuer by means of a notice given in accordance with the provisions of 
this Section 5.5, which address initially is the address set forth in the 
Purchase Agreement with respect to the Initial Purchasers; and (b) if to the 
Issuer, initially at the Issuer's address set forth in the Purchase 
Agreement, and thereafter at such other address of which notice is given in 
accordance with the provisions of this Section 5.5.
          All such notices and communications shall be deemed to have been duly
given: at the time delivered by hand, if personally delivered; two business days
after being deposited in the mail, postage prepaid, if mailed; when answered
back, if telexed; when receipt is acknowledged, if telecopied; and on the next
business day if timely delivered to an air courier guaranteeing overnight
delivery.
          Copies of all such notices, demands, or other communications shall be
concurrently delivered by the person giving the same to the Trustee under the
Indenture, at the address specified in such Indenture.
          5.6  SUCCESSOR AND ASSIGNS.  This Agreement shall inure to the benefit
of and be binding upon the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
assignment, subsequent Holders; PROVIDED that nothing herein shall be deemed to
permit any assignment, transfer or other disposition of Registrable Securities
in violation of the terms of the Purchase Agreement or the Indenture.  If any
transferee of any Holder shall acquire Registrable Securities, in any manner,
whether by operation of law or otherwise, such Registrable Securities shall be
held subject to all of the terms of this Agreement, and by taking and holding
such Registrable Securities such Person shall be conclusively deemed to have
agreed to be bound by and to perform all of the terms and provisions of this
Agreement, including the restrictions on resale set forth in this Agreement and,
if applicable, the Purchase Agreement, and such Person shall be entitled to
receive the benefits hereof.
          5.7  THIRD PARTY BENEFICIARIES.  The Initial Purchasers (even if the
Initial Purchasers are not Holders of Registrable Securities) shall be third
party 
                                    -29-
beneficiaries to the agreements made hereunder between the Issuer, on the one 
hand, and the Holders, on the other hand, and shall have the right to enforce 
such agreements directly to the extent they deem such enforcement necessary 
or advisable to protect their rights or the rights of Holders hereunder.  
Each Holder of Registrable Securities shall be a third party beneficiary to 
the agreements made hereunder between the Issuer, on the one hand, and the 
Initial Purchasers, on the other hand, and shall have the right to enforce 
such agreements directly to the extent it deems such enforcement necessary or 
advisable to protect its rights hereunder.
          5.8  SPECIFIC ENFORCEMENT.  Without limiting the remedies available to
the Initial Purchasers and the Holders, the Issuer acknowledges that any failure
by the Issuer to comply with its obligations under Sections 2.1 through 2.4
hereof may result in material irreparable injury to the Initial Purchasers or
the Holders for which there is no adequate remedy at law, that it would not be
possible to measure damages for such injuries precisely and that, in the event
of any such failure, the Initial Purchasers or any Holder may obtain such relief
as may be required to specifically enforce the Issuer's obligations under
Sections 2.1 through 2.4 hereof
          5.9  RESTRICTION ON RESALES.  Until the expiration of two years after
the original issuance of the Securities, the Issuer will not, and will cause its
"affiliates" (as such term is defined in Rule 144(a)(1) under the ▇▇▇▇ ▇▇▇) not
to, resell to anyone other than the Issuer any Securities which are "restricted
securities" (as such term is defined under Rule 144(a)(3) under the ▇▇▇▇ ▇▇▇)
that have been reacquired by any of them and shall immediately upon any purchase
of any such Securities submit such Securities to the Trustee for cancellation
after payment therefor by the Issuer (if the Securities are being submitted by
an affiliate of the Issuer).
          5.10 COUNTERPARTS.  This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.
          5.11 HEADINGS.  The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.
          5.12 GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO THE
PRINCIPLES OF CONFLICT OF LAWS THEREOF.
          5.13 SEVERABILITY.  In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every 
                                    -30-
other respect and of the remaining provisions contained herein shall not be 
affected or impaired thereby.
                                    -31-
          IN WITNESS WHEREOF, the parties have executed this Agreement as of the
date first written above.
