     manner draw into question the validity or enforceability of any of the
     Transaction Documents or any action taken or to be taken pursuant thereto;

     loan agreement or other material agreement or instrument to which it is a
     party or by which it is bound or to which any of its property or assets is

     or bodies which are necessary or desirable for the ownership of their
     respective properties or the conduct of their respective businesses as
     described in the Offering Memorandum, except where the failure to possess

     Adverse Effect, and neither the Company nor any of its subsidiaries has
     received notification of any revocation or modification of any such
     license, certificate, authorization or permit or has any reason to believe

     such counsel, is material and is required to be stated therein or is
     necessary to make the statements therein not misleading.

          (c)  All corporate proceedings and other legal matters incident to the
     authorization, form and validity of each of the Transaction Documents and
     the Offering Memorandum, and all other legal matters relating to the

     furnished to the Initial Purchasers their written opinion, as special
     communications counsel to the Company, addressed to the Initial Purchasers

     untrue statement of a material fact and did not omit to state a material
     fact required to be stated therein or necessary in order to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading, and since the date of the Offering Memorandum, no
     event has occurred which should have been set forth in a supplement or
     amendment to the Offering Memorandum so that the Offering Memorandum (as so
     amended or supplemented) would not include any untrue statement of a
     material fact and would not omit to state a material fact required to be
     stated therein or necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading,
     (iii) as of the Closing Date, the representations and warranties of the
     Company or the Subsidiary Guarantor, as applicable, in this Agreement are
     true and correct in all material respects, the Company or the Subsidiary
     Guarantor, as applicable, has complied with all agreements and satisfied
     all conditions on its part to be performed or satisfied hereunder on or
     prior to the Closing Date and (iv) with respect to officers of the Company
     only, subsequent to the date of the most recent financial statements
     contained in the Offering Memorandum, there has been no material adverse
     change in the financial position or results of operation of the Company or
     any of its subsidiaries, or any material change, or any material
     development including a prospective material change, in or affecting the
     condition (financial or otherwise), results of operations, business or
     prospects of the Company and its subsidiaries taken as a whole, which is
     not disclosed in the Offering Memorandum.

          (i)  The Initial Purchasers shall have received a counterpart of the
     Registration Rights Agreement which shall have been executed and delivered
     by a duly authorized officer of the Company and the Subsidiary Guarantor.

          (j)  The Indenture shall have been duly executed and delivered by the

                                                                              21


     (l)  If any event shall have occurred that requires the Company under
Section 4(d) to prepare an amendment or supplement to the Offering Memorandum,
such amendment or supplement shall have been prepared, the Initial Purchasers
shall have been given a reasonable opportunity to comment thereon, and copies
thereof shall have been delivered to the Initial Purchasers reasonably in
advance of the Closing Date.

     (m)  There shall not have occurred any invalidation of Rule 144A under
the Securities Act by any court or any withdrawal or proposed withdrawal of any
rule or regulation under the Securities Act or the Exchange Act by the
Commission or any amendment or proposed amendment thereof by the Commission
which in the reasonable judgment of the Initial Purchasers would materially
impair the ability of the Initial Purchasers to purchase, hold or effect resales
of the Securities as contemplated hereby.

     (n)  Subsequent to the execution and delivery of this Agreement or, if
earlier, the dates as of which information is given in the Offering Memorandum
(exclusive of any amendment or supplement thereto), there shall not have been
any change in the capital stock or long-term debt (other than, with respect to
long-term debt, the issuance of additional junior subordinated notes pursuant to
the Lucent Note Purchase Agreement) or any change, or any development involving
a prospective change, in or affecting the condition (financial or otherwise),
results of operations, business or prospects of the Company and its subsidiaries
taken as a whole, the effect of which, in any such case described above, is, in
the reasonable judgment of the Initial Purchasers, so material and adverse as to
make it impracticable or inadvisable to proceed with the sale or delivery of the
Securities on the terms and in the manner contemplated by this Agreement and the
Offering Memorandum (exclusive of any amendment or supplement thereto).

     (o)  No action shall have been taken and no statute, rule, regulation
or order shall have been enacted, adopted or issued by any governmental agency
or body which would, as of the Closing Date, prevent the issuance or sale of the
Securities in any jurisdiction in which issuance or sale of the Securities is
contemplated by the Offering Memorandum; and no injunction, restraining order or
order of any other nature by any federal or state court of competent
jurisdiction shall have been issued as of the Closing Date which would prevent

     (p)  Subsequent to the execution and delivery of this Agreement (i) no
downgrading shall have occurred in the rating accorded the Securities or any of
the Company's other debt securities or preferred stock by any "nationally
recognized statistical rating organization", as such term is defined by the
Commission for purposes of Rule 436(g)(2) of the rules and regulations of the
Commission under the Securities Act, and (ii) no such organization shall have
publicly announced that it has under surveillance or review (other than an
announcement with positive implications of a possible upgrading), its rating of
the Securities or any of the Company's other debt securities or preferred stock.

     (q)  Subsequent to the execution and delivery of this Agreement there
shall not have occurred any of the following: (i) trading in securities
generally on the New York


                                                                              22

     Stock Exchange, the American Stock Exchange or the over-the-counter market
     shall have been suspended or limited, or minimum prices shall have been
     established on any such exchange or market by the Commission, by any such
     exchange or by any other regulatory body or governmental authority having
     jurisdiction, or trading in any securities of the Company on any exchange
     or in the over-the-counter market shall have been suspended, (ii) any
     moratorium on commercial banking activities shall have been declared by
     federal or New York state authorities, (iii) an outbreak or escalation of
     hostilities or a declaration by the United States of a national emergency
     or war or (iv) a material adverse change in general economic, political or
     financial conditions (or the effect of international conditions on the
     financial markets in the United States shall be such) the effect of which,
     in the case of this clause (iv), is, in the judgment of the Initial
     Purchasers, so material and adverse as to make it impracticable or
     inadvisable to proceed with the sale or the delivery of the Securities on
     the terms and in the manner contemplated by this Agreement and in the
     Offering Memorandum (exclusive of any amendment or supplement thereto).

          All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Initial Purchasers.

          6.  Termination.  The obligations of the Initial Purchasers hereunder
may be terminated by the Initial Purchasers, in their absolute discretion, by
notice given to and received by the Company prior to delivery of and payment for
the Securities if, prior to that time, any of the events described in Section
5(m), (n), (o), (p) or (q) shall have occurred and be continuing.

          7.  Defaulting Initial Purchasers.  (a)  If, on the Closing Date, any
Initial Purchaser defaults in the performance of its obligations under this
Agreement, the non-defaulting Initial Purchasers may make arrangements for the
purchase of the Securities which such defaulting Initial Purchaser agreed but
failed to purchase by other persons satisfactory to the Company and the non-
defaulting Initial Purchasers, but if no such arrangements are made within 36
hours after such default, this Agreement shall terminate without liability on
the part of the non-defaulting Initial Purchasers or the Company, except that
the Company and the Subsidiary Guarantor will continue to be liable for the
payment of expenses to the extent set forth in Sections 8 and 12 and except that
the provisions of Sections 9 and 10 shall not terminate and shall remain in
effect.  As used in this Agreement, the term "Initial Purchasers" includes, for
all purposes of this Agreement unless the context otherwise requires, any party
not listed in Schedule 1 hereto that, pursuant to this Section 7, purchases
Securities which a defaulting Initial Purchaser agreed but failed to purchase.

          (b)  Nothing contained herein shall relieve a defaulting Initial
Purchaser of any liability it may have to the Company or any non-defaulting
Initial Purchaser for damages caused by its default.  If other persons are
obligated or agree to purchase the Securities of a defaulting Initial Purchaser,
either the non-defaulting Initial Purchasers or the Company may postpone the
Closing Date for up to seven full business days in order to effect any changes
that in the opinion of counsel for the Company or counsel for the Initial
Purchasers may be necessary in the Offering Memorandum or in any other document
or arrangement, and the Company agrees to


                                                                              23

promptly prepare any amendment or supplement to the Offering Memorandum that
effects any such changes.

          8.  Reimbursement of Initial Purchasers' Expenses.  If (a) this
Agreement shall have been terminated pursuant to Section 6 or 7, (b) the Company
shall fail to tender the Securities for delivery to the Initial Purchasers for
any reason permitted under this Agreement or (c) the Initial Purchasers shall
decline to purchase the Securities for any reason permitted under this
Agreement, the Company and the Subsidiary Guarantor shall reimburse the Initial
Purchasers for such out-of-pocket expenses (including reasonable fees and
disbursements of counsel) as shall have been reasonably incurred by the Initial
Purchasers in connection with this Agreement and the proposed purchase and
resale of the Securities.  If this Agreement is terminated pursuant to Section 7
by reason of the default of one or more of the Initial Purchasers, the Company
and the Subsidiary Guarantor shall not be obligated to reimburse any defaulting
Initial Purchaser on account of such expenses.

          9.  Indemnification.  (a)  The Company and the Subsidiary Guarantor
shall jointly and severally indemnify and hold harmless each Initial Purchaser,
its affiliates, their respective officers, directors, employees, representatives
and agents, and each person, if any, who controls any Initial Purchaser within
the meaning of the Securities Act or the Exchange Act (collectively referred to
for purposes of this Section 9(a) and Section 10 as an Initial Purchaser), from
and against any loss, claim, damage or liability, joint or several, or any
action in respect thereof (including, without limitation, any loss, claim,
damage, liability or action relating to purchases and sales of the Securities),
to which that Initial Purchaser may become subject, whether commenced or
threatened, under the Securities Act, the Exchange Act, any other federal or
state statutory law or regulation, at common law or otherwise, insofar as such
loss, claim, damage, liability or action arises out of, or is based upon, (i)
any untrue statement or alleged untrue statement of a material fact contained in
the Preliminary Offering Memorandum or the Offering Memorandum or in any
amendment or supplement thereto or in any information provided by the Company
pursuant to Section 4(e) or (ii) the omission or alleged omission to state
therein a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading, and shall reimburse each Initial Purchaser promptly
upon demand for any legal or other expenses reasonably incurred by that Initial
Purchaser in connection with investigating or defending or preparing to defend
against or appearing as a third party witness in connection with any such loss,
claim, damage, liability or action as such expenses are incurred; provided,
however, that the Company and the Subsidiary Guarantor shall not be liable in
any such case to the extent that any such loss, claim, damage, liability or
action arises out of, or is based upon, an untrue statement or alleged untrue
statement in or omission or alleged omission from any of such documents in
reliance upon and in conformity with any Initial Purchasers' Information; and
provided, further, that with respect to any such untrue statement in or omission
from the Preliminary Offering Memorandum, the indemnity agreement contained in
this Section 9(a) shall not inure to the benefit of any such Initial Purchaser
to the extent that the sale to the person asserting any such loss, claim,
damage, liability or action was an initial resale by such Initial Purchaser and
any such loss, claim, damage, liability or action of or with respect to such
Initial Purchaser results from the fact that both (A) to the extent required by
applicable law, a copy of the Offering Memorandum was not sent or given to such
person at or prior to the written confirmation of the sale of such Securities to
such person and (B) the untrue statement in or


                                                                              24

omission from the Preliminary Offering Memorandum was corrected in the Offering
Memorandum unless, in either case, such failure to deliver the Offering
Memorandum was a result of non-compliance by the Company with Section 4(b).

          (b)  Each Initial Purchaser, severally and not jointly, shall
indemnify and hold harmless the Company, its affiliates, their respective
officers, directors, employees, representatives and agents, and each person, if
any, who controls the Company within the meaning of the Securities Act or the
Exchange Act (collectively referred to for purposes of this Section 9(b) and
Section 10 as the Company), from and against any loss, claim, damage or
liability, joint or several, or any action in respect thereof, to which the
Company may become subject, whether commenced or threatened, under the
Securities Act, the Exchange Act, any other federal or state statutory law or
regulation, at common law or otherwise, insofar as such loss, claim, damage,
liability or action arises out of, or is based upon, (i) any untrue statement or
alleged untrue statement of a material fact contained in the Preliminary
Offering Memorandum or the Offering Memorandum or in any amendment or supplement
thereto or (ii) the omission or alleged omission to state therein a material
fact required to be stated therein or necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, but in each case only to the extent that the untrue statement or
alleged untrue statement or omission or alleged omission was made in reliance
upon and in conformity with any Initial Purchasers' Information, and shall
reimburse the Company promptly upon demand for any legal or other expenses
reasonably incurred by the Company in connection with investigating or defending
or preparing to defend against or appearing as a third party witness in
connection with any such loss, claim, damage, liability or action as such
expenses are incurred.

          (c)  Promptly after receipt by an indemnified party under this Section
9 of notice of any claim or the commencement of any action, the indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party pursuant to Section 9(a) or 9(b), notify the indemnifying
party in writing of the claim or the commencement of that action; provided,
however, that the failure to notify the indemnifying party shall not relieve it
from any liability which it may have under this Section 9 except to the extent
that it has been prejudiced (through the forfeiture of substantive rights or
defenses) by such failure; and, provided, further, that the failure to notify
the indemnifying party shall not relieve it from any liability which it may have
to an indemnified party otherwise than under this Section 9.  If any such claim
or action shall be brought against an indemnified party, and it shall notify the
indemnifying party thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it wishes, jointly with any other
similarly notified indemnifying party, to assume the defense thereof with
counsel reasonably satisfactory to the indemnified party.  After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 9 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that an
indemnified party shall have the right to employ its own counsel in any such
action, but the fees, expenses and other charges of such counsel for the
indemnified party will be at the expense of such indemnified party unless (i)
the employment of counsel by the indemnified party has been authorized in
writing by the indemnifying party, (ii) the indemnified party has reasonably
concluded (based upon advice of counsel to the indemnified party) that there may
be legal defenses available to it or other indemnified parties that are
different from or in addition to those


                                                                              25

available to the indemnifying party, (iii) a conflict or potential conflict
exists (based upon advice of counsel to the indemnified party) between the
indemnified party and the indemnifying party (in which case the indemnifying
party will not have the right to direct the defense of such action on behalf of
the indemnified party) or (iv) the indemnifying party has not in fact employed
counsel reasonably satisfactory to the indemnified party to assume the defense
of such action within a reasonable time after receiving notice of the
commencement of the action, in each of which cases the reasonable fees,
disbursements and other charges of counsel will be at the expense of the
indemnifying party or parties. It is understood that the indemnifying party or
parties shall not, in connection with any proceeding or related proceedings in
the same jurisdiction, be liable for the reasonable fees, disbursements and
other charges of more than one separate firm of attorneys (in addition to any
local counsel) at any one time for all such indemnified party or parties. Each
indemnified party, as a condition of the indemnity agreements contained in
Sections 9(a) and 9(b), shall use all reasonable efforts to cooperate with the
indemnifying party in the defense of any such action or claim. No indemnifying
party shall be liable for any settlement of any such action effected without its
written consent (which consent shall not be unreasonably withheld), but if
settled with its written consent or if there be a final judgment for the
plaintiff in any such action, the indemnifying party agrees to indemnify and
hold harmless any indemnified party from and against any loss or liability by
reason of such settlement or judgment. No indemnifying party shall, without the
prior written consent of the indemnified party (which consent shall not be
unreasonably withheld), effect any settlement of any pending or threatened
proceeding in respect of which any indemnified party is or could have been a
party and indemnity could have been sought hereunder by such indemnified party
unless such settlement includes an unconditional release of such indemnified
party from all liability on claims that are the subject matter of such
proceeding.

          The obligations of the Company, the Subsidiary Guarantor and the
Initial Purchasers in this Section 9 and in Section 10 are in addition to any
other liability that the Company, the Subsidiary Guarantor or the Initial
Purchasers, as the case may be, may otherwise have, including in respect of any
breaches of representations, warranties and agreements made herein by any such
party.

          10.  Contribution.  If the indemnification provided for in Section 9
is unavailable or insufficient to hold harmless an indemnified party under
Section 9(a) or 9(b), then each indemnifying party shall, in lieu of
indemnifying such indemnified party, contribute to the amount paid or payable by
such indemnified party as a result of such loss, claim, damage or liability, or
action in respect thereof, (i) in such proportion as shall be appropriate to
reflect the relative benefits received by the Company and the Subsidiary
Guarantor on the one hand and the Initial Purchasers on the other from the
offering of the Securities or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company and the Subsidiary Guarantor on the one
hand and the Initial Purchasers on the other with respect to the statements or
omissions that resulted in such loss, claim, damage or liability, or action in
respect thereof, as well as any other relevant equitable considerations.  The
relative benefits received by the Company and the Subsidiary Guarantor on the
one hand and the Initial Purchasers on the other with respect to such offering
shall be deemed to be in the same proportion as the total net proceeds from the
offering of the Securities purchased under this Agreement (before deducting
expenses) received by or on behalf of the Company and the


                                                                              26

Subsidiary Guarantor, on the one hand, and the total discounts and commissions
received by the Initial Purchasers with respect to the Securities purchased
under this Agreement, on the other, bear to the total gross proceeds from the
sale of the Securities under this Agreement. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to the Company or information supplied by the Company
and the Subsidiary Guarantor on the one hand or to any Initial Purchasers'
Information on the other, the intent of the parties and their relative
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. The Company, the Subsidiary Guarantor and the
Initial Purchasers agree that it would not be just and equitable if
contributions pursuant to this Section 10 were to be 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 that does not take into account
the equitable considerations referred to herein. The amount paid or payable by
an indemnified party as a result of the loss, claim, damage or liability, or
action in respect thereof, referred to above in this Section 10 shall be deemed
to include, for purposes of this Section 10, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending or preparing to defend any such action or claim. Notwithstanding
the provisions of this Section 10, no Initial Purchaser shall be required to
contribute any amount in excess of the amount by which the total discounts and
commissions received by such Initial Purchaser with respect to the Securities
purchased by it under this Agreement exceeds the amount of any damages which
such Initial Purchaser has otherwise paid or become liable to pay by reason of
any 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 Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The Initial Purchasers'
obligations to contribute as provided in this Section 10 are several in
proportion to their respective purchase obligations and not joint.

          11.  Persons Entitled to Benefit of Agreement.  This Agreement shall
inure to the benefit of and be binding upon the Initial Purchasers, the Company,
the Subsidiary Guarantor and their respective successors.  This Agreement and
the terms and provisions hereof are for the sole benefit of only those persons,
except as provided in Sections 9 and 10 with respect to affiliates, officers,
directors, employees, representatives, agents and controlling persons of the
Company, the Subsidiary Guarantor and the Initial Purchasers and in Section 4(e)
with respect to holders and prospective purchasers of the Securities.  Nothing
in this Agreement is intended or shall be construed to give any person, other
than the persons referred to in this Section 11, any legal or equitable right,
remedy or claim under or in respect of this Agreement or any provision contained
herein.

          12.  Expenses.  The Company and the Subsidiary Guarantor agree with
the Initial Purchasers to pay (a) the costs incident to the authorization,
issuance, sale, preparation and delivery of the Securities and any taxes payable
in that connection; (b) the costs incident to the preparation, printing and
distribution of the Preliminary Offering Memorandum, the Offering Memorandum and
any amendments or supplements thereto; (c) the costs of reproducing and
distributing each of the Transaction Documents; (d) the costs incident to the
preparation, printing and delivery of the certificates evidencing the
Securities, including stamp duties and transfer taxes, if any, payable upon
issuance of the Securities; (e) the fees and expenses of the Company's counsel
and independent accountants; (f) the fees and expenses of qualifying the


                                                                              27

Securities under the securities laws of the several jurisdictions as provided in
Section 4(h) and of preparing, printing and distributing Blue Sky Memoranda
(including related fees and expenses of counsel for the Initial Purchasers); (g)
any fees charged by rating agencies for rating the Securities; (h) the fees and
expenses of the Trustee and any paying agent (including related fees and
expenses of any counsel to such parties); (i) all expenses and application fees
incurred in connection with the application for the inclusion of the Securities
on the PORTAL Market and the approval of the Securities for book-entry transfer
by DTC; and (j) all other costs and expenses incident to the performance of the
obligations of the Company under this Agreement which are not otherwise
specifically provided for in this Section 12; provided, however, that except as
provided in this Section 12 and Section 8, the Initial Purchasers shall pay
their own costs and expenses.

          13.  Survival.  The respective indemnities, rights of contribution,
representations, warranties and agreements of the Company, the Subsidiary
Guarantor and the Initial Purchasers contained in this Agreement or made by or
on behalf of the Company, the Subsidiary Guarantor or the Initial Purchasers
pursuant to this Agreement or any certificate delivered pursuant hereto shall
survive the delivery of and payment for the Securities and shall remain in full
force and effect, regardless of any termination or cancelation of this Agreement
or any investigation made by or on behalf of any of them or any of their
respective affiliates, officers, directors, employees, representatives, agents
or controlling persons.

          14.  Notices, etc.  All statements, requests, notices and agreements
hereunder shall be in writing, and:
