     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
<PAGE>

     which should have been set forth in a supplement or amendment to the

     necessary in order to make the statements therein, in the light of 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

     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

     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

     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 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
<PAGE>

     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 the issuance or sale of the Securities in any
     jurisdiction in which the issuance or sale of the Securities is
     contemplated by the Offering Memorandum.

          (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 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
<PAGE>

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 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
<PAGE>

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 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
<PAGE>

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 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
<PAGE>

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 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
<PAGE>

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
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:
