animal life or any other natural resource) or to human health or safety,
including, without limitation, statutes, regulations, and rules of common law
regulating or imposing liability or standards of conduct with respect to (A)

          (w) Intellectual Property. To the Company's and the Guarantors'
knowledge, the Company and the Subsidiaries own, possess or can acquire on
reasonable terms, adequate trademarks, trade names and other rights to
inventions, know-how, patents, copyrights, confidential information and other
intellectual property (collectively, "intellectual property rights") necessary
to operate the Projects as contemplated by the Offering Materials, and have not
received any notice of infringement of or conflict with asserted rights of
others with respect to any intellectual property rights.

          (x) Investment Company Act. The Company and the Subsidiaries are not
and, after giving effect to the offering and sale of the Securities, neither the
Company nor any Subsidiary will be, an "investment company," or an entity
"controlled" by an investment company, as such terms are defined in the
Investment Company Act of 1940, as amended (the "Investment Company Act").


                                       10



          (y) Projections. The financial projections and other projected
financial and operating data relating to the Company, the Subsidiaries and the
Projects contained in the Offering Materials (including, without limitation, in
the Independent Engineer's Report, the Geothermal Consultant's Report and the

Company and the Guarantors as to the matters covered thereby, reasonable as of
their date, and (ii) are based on assumptions that the Company and the
Guarantors consider reasonable as to all factual and legal matters material to
the estimates therein and (iii) are in all material respects consistent with the
provisions of the Transaction Documents. To the knowledge of the Company and the
Guarantors, none of the information forming the basis of such projections and
assumptions has changed since they were originally prepared so as to materially
affect such projections and assumptions.

          (z) Rule 144A/Regulation S. (i) The Securities are eligible for resale
pursuant to Rule 144A and when the Securities are issued and delivered pursuant
to the Indenture and this Agreement, the Securities will not be of the same
class (within the meaning of Rule 144A) as securities which are listed on a
national securities exchange registered under Section 6 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act") or quoted in a U.S.
automated inter-dealer quotation system.

               (ii) Except for the offer and sale of the Securities as
contemplated under this Agreement, none of the Company or any of its Affiliates,
nor any Person acting on its or their behalf (x) has, within the six-month
period prior to the date hereof, offered or sold in the United States or to any
U.S. person (as such terms are defined in Regulation S under the Securities Act)

restrictions requirement of Regulation S. Neither the Company nor any of its
Affiliates have entered and neither the Company nor any of its Affiliates will
enter into any contractual arrangement with respect to the distribution of the
Securities except for this Agreement.

               (iii) The proceeds to the Company from the offering of the
Securities will not be used to purchase or carry any security in any manner
which would violate Regulations T, U or X of the Federal Reserve Board.

          (aa) Securities Act Registration. Subject to compliance by the
Purchaser with the representations, warranties and agreements set forth in
Section 4 hereof, it is not necessary in connection with the offer, sale and
delivery of the Securities to the Purchaser (and in connection with the original
resale of the Securities by the Purchaser) in the manner contemplated by this
Agreement and the Offering Materials to register the Securities under the
Securities Act or to qualify the Indenture under the Trust Indenture Act of
1939.

          (bb) Brokerage Commissions. Except as disclosed in the Offering
Materials, there are no contracts, agreements or understandings between the
Company or any Affiliate of


                                       11



the Company and any other Person that would give rise to a valid claim against
the Company or the Purchaser for a brokerage commission, finder's fee or other
like payment in connection with the issuance, sale or delivery of the
Securities.

          (cc) Bank Accounts. At the Time of Delivery, the Company and the

(and do not intend to abandon) any of the Projects or any Plant.

          (ee) Project Documents. All of the Project Documents previously
provided to the Purchaser are true, complete and correct copies in all material
respects.

          (ff) Solvency. After giving effect to the issuance of the Securities
by the Company and the Guarantors, the use of proceeds therefrom and the
performance by the Company and the Guarantors of their respective obligations
pursuant to the Transaction Documents, the sum of the Assets, at a fair
valuation, of each of the Company and the Subsidiaries will exceed their
respective debts and the Company and the Guarantors will not have incurred (as a
result of the issuance of the Securities and the assumption of their obligations
pursuant to the Transaction Documents) and do not intend to incur, and do not
believe that they will incur, debts beyond their ability to pay such debts as
such debts mature.

          (gg) Labor Matters. Neither the Company nor any Subsidiary has any
employees. To the Company's knowledge, no labor dispute exists with the
employees of Ormat Nevada Inc. that provide services to the Projects that would
result in a Material Adverse Effect.

          (hh) Collateral. The Company and the Guarantors have delivered or, at
the Time of Delivery, will deliver to the Collateral Agent all Collateral which,
pursuant to Applicable Law, must be delivered to the Collateral Agent in order
to perfect the security interest therein as a first priority Lien (including,
without limitation, any letters of credit, bonds or notes for which the Company
or a Guarantor is the beneficiary).

          (ii) Security Documents. The Security Documents create valid first
priority liens on and/or security interests in all of the Collateral in favor of
the Secured Parties, subject only to Permitted Liens of the type described in
clauses (b), (c), (d), (e), (f), (g) and (j) of the definition thereof.

          (jj) Absence of Defaults. No condition exists which would constitute a
Default or an Event of Default under the Indenture or a default or event of
default (however defined) pursuant to any of the other Financing Documents.

          (kk) Registration Statements. There are no contracts, agreements or
understandings between the Company or any Subsidiary, on the one hand, and any
Person, on the other hand, granting such Person the right to require the Company
or any Subsidiary, as the case may be, to file a registration statement under
the Securities Act with respect to any securities of the Company or any
Subsidiary owned or to be owned by such Person or to require the Company


                                       12



or any Guarantor to include such securities in any securities being registered
pursuant to a registration statement filed by the Company or any Subsidiary
under the Securities Act.

          (ll) Material Adverse Effect. Neither the Company nor any Subsidiary
has sustained, since the date of the latest audited financial statements
included in the Offering Memorandum, any loss or interference with its business
from fire, explosion, flood or other calamity, whether or not covered by
insurance, or from any labor dispute or court or governmental action, order or
decree, otherwise than as set forth or contemplated in the Offering Memorandum
or that would not result in a Material Adverse Effect; and, since such date
other than in connection with the Offering and the application of the proceeds
therefrom, there has not been any material adverse change, or any development
involving a prospective material adverse change, in or affecting the condition,
financial or otherwise, stockholder's equity, results of operations or business
of the Company and the Subsidiaries, taken as a whole, otherwise than as set
forth or contemplated in the Offering Memorandum.

          (mm) Independent Public Accounts. PricewaterhouseCoopers LLP who have
certified certain financial statements of the Company and the Subsidiaries whose
reports appear in the Offering Materials and who have delivered the Initial
Letter referred to in Section 8(d) hereof concurrently with the execution and
delivery of this Agreement, are independent certified public accountants with
respect to the Company under Rule 101 of the Code of Professional Conduct of the

to the Company under Rule 101 of the Code of Professional Conduct of the
American Institute of Certified Public Accountants, and its rulings and
interpretations during the periods covered by the financial statements on which
they reported that are contained in the Offering Materials.

          (nn) Liabilities. Since the date as of which information is given in
the Preliminary Offering Memorandum through the date hereof, and except as may
otherwise be disclosed in the Offering Memorandum, neither the Company nor any
Subsidiary has (i) issued or granted any securities, (ii) incurred any liability
or obligation, direct or contingent, other than liabilities and obligations
which were incurred in the ordinary course of business, (iii) entered into any
transaction not in the ordinary course of business or (iv) declared or paid any
dividend on its capital stock.

          (oo) Books and Records. Each of the Company and the Subsidiaries (i)
makes and keeps accurate books and records and (ii) maintains internal
accounting controls which provide reasonable assurance that (A) transactions are
executed in accordance with management's authorization, (B) transactions are
recorded as necessary to permit preparation of its financial statements and to
maintain accountability for its assets, (C) access to its assets is permitted
only in accordance with management's authorization and (D) the reported

          (pp) FERC. Each of the Projects is a Qualifying Facility that is
eligible for the regulatory exemptions from the Federal Power Act, as amended,
certain state laws and regulations and the Public Utility Holding Company Act of
1935, as amended, as set forth in 18 C.F.R. Sections 292.601 and 292.602.


                                       13



          (qq) Subordinated Credit Agreement. The Subordinated Credit Agreement
between Ormat Nevada Inc. and the Company has been duly authorized and executed
by the Company and Ormat Nevada Inc. and constitutes Subordinated Debt for
purposes of the Indenture.

          (rr) Deeds of Trust. Each of the Company and any Guarantor that
possesses any property, leases, easements, licenses, rights of way or other
property interests will have, as of the Time of Delivery, executed and delivered

of way or other property interests of the Company or such Guarantor.

          (a) It (i) is a "qualified institutional buyer" within the meaning of

a private sale exempt from registration under the Securities Act.

          (b) It will offer and sell the Securities only to (i) Persons whom it
reasonably believes are QIBs within the meaning of Rule 144A or, if any such
Person is buying for one or more institutional accounts for which such Person is
acting as fiduciary or agent, only when such Person has represented to the
Purchaser that each such account is a QIB to whom such notice has been given
that such sale or delivery is being made in reliance on Rule 144A, in each case
in transactions meeting the requirements of Rule 144A; or (ii) Persons whom it
reasonably believes, at the time any buy order for Securities was or is
originated, were or are outside the United States and were or are not U.S.

foregoing, following the sale of the Securities by the Purchaser to subsequent

                                       14



          (c) No action has been or will be taken by the Purchaser in any
jurisdiction that would permit or constitute a public offering of the Securities
in any such jurisdiction; and the Purchaser has not offered or sold and it will
not offer or sell the Securities by any form of general solicitation or general
advertising, including but not limited to the methods described in Rule 502(c)
under Regulation D under the Securities Act or in any manner involving a public

Time of Delivery or the consummation of the resale of all of the Securities
purchased hereunder.

          (d) The Purchaser represents that, with respect to any offer or sale
made by the Purchaser in reliance on Regulation S, neither the Purchaser nor any
of its Affiliates nor any employees or representatives acting on its behalf has
engaged or will engage in any directed selling efforts with respect to the
Securities, and that any advertisement undertaken by the Purchaser will comply
with Rule 902(c)(3) of Regulation S. The Purchaser agrees that, at or prior to
confirmation of any sale of Securities made in reliance on Regulation S, the
Purchaser will send to each distributor, dealer or Person receiving a selling
concession, fee or other remuneration that purchases the Securities from it a
confirmation or notice to substantially the following effect:

          "The Securities covered hereby have not been registered under the U.S.
          Securities Act of 1933 (the "Securities Act") and may not be offered
          or sold within the United States or to, or for the account or benefit
          of U.S. Persons (i) as part of their distribution at any time or (ii)
          otherwise until 40 days after the date of the commencement of the
          offering and the closing date, except in either case in accordance
          with Regulation S (or Rule 144A if available) under the Securities
          Act. Terms used above have the meanings given to them by Regulation
          S."

Terms used in this subsection (d) which are defined in Regulation S have the
meanings given to them therein.

          (e) The Purchaser, and each of its Affiliates, have only communicated
or caused to be communicated and will only communicate or cause to be
communicated any invitation or inducement to engage in investment activity
(within the meaning of Section 21 of the Financial Services and Markets Act 2000
(the "FSMA")) received by it in connection with the issue or sale of any
Securities in circumstances in which Section 21(1) of the FSMA does not apply to
it.

          (f) The Purchaser, and each of its Affiliates, have complied with and

Materials in or from any jurisdiction except in compliance with any applicable
rules and regulations of any such jurisdiction.

          (h) In relation to each member state of the European Economic Area
which has implemented the Prospectus Directive, each, a Relevant Member State,
that with effect from and including the date on which the Prospectus Directive
is implemented in that Relevant Member State, or the relevant implementation
date, the Purchaser has not made and will not make an offer of the Securities to
the public in that Relevant Member State prior to the publication of a
prospectus in relation to the Securities which has been approved by the
competent authority in that Relevant Member State or, where appropriate,
approved in another Relevant Member State and notified to the competent
authority in that Relevant Member State, all in accordance with the Prospectus
Directive, except that the Purchaser may, with effect from and including the
relevant implementation date, make an offer of the Securities to the public in
that Relevant Member State at any time:

               (i)  to legal entities which are authorized or regulated to
operate in the financial markets or, if not so authorized or regulated, whose
corporate purpose is solely to invest in securities;

               (ii) to any legal entity which has two or more of (A) an average
of at least 250 employees during the last financial year; (B) a total balance
sheet of more than (euro)43,000,000 and (C) an annual net turnover of more than
(euro)50,000,000, as shown in its last annual or consolidated account; or

               (ii) in any other circumstances which do not require the
publication by the Company of a prospectus pursuant to Article 3 of the
Prospectus Directive.

          For the purposes of this Section 4(h), the expression an "offer of the
Securities to the public" in relation to the Securities in any Relevant Member
State means the communication in any form and by any means of sufficient
information on the terms of the offer and the Securities to be offered so as to
enable an investor to decide to purchase or subscribe to the Securities, as the
same may be varied in that member state by any measure implementing the
Prospectus Directive in that member state and the expression "Prospectus
Directive" means Directive 2003/71/EC and includes any relevant implementing
measure in each Relevant Member State.

          The Purchaser understands that the Company and the Guarantors and, for
purposes of the opinions to be delivered to the Purchaser pursuant to Sections
8(a) hereof, counsel to the Company and counsel to the Purchaser, will rely upon
the accuracy and truth of the foregoing representations, warranties and
agreements and the Purchaser hereby consents to such reliance.

     5.   Delivery and Payment.

          (a) Notes will be issued in registered form in denominations of $1,000
and integral multiples of $1,000 in excess thereof. The Notes sold in reliance
on Rule 144A or Regulation S will initially be represented, in each case, by one
or more global notes in registered


                                       16



form without coupons attached (collectively, the "Global Note(s)"). Each Global
Note relating to the Notes offered and sold pursuant to Regulation S will be
authenticated by the Trustee and deposited with the Trustee, as custodian for
DTC (the "Global Depositary") for the respective accounts of Euroclear Bank,
S.A./N.V., as operator of the Euroclear System ("Euroclear"), and Clearstream,
Luxembourg Banking Societe Anonyme ("Clearstream"), at the Time of Delivery.
Each Global Note relating to the Notes offered and sold pursuant to Rule 144A
will be authenticated by the Trustee and deposited with the Trustee, as
custodian for DTC (the "U.S. Custodian") at the Time of Delivery. The Global
Notes and interests therein will be held in book-entry form and will not be
exchangeable for certificated Notes except under certain limited circumstances
described in the Offering Memorandum. In such cases, certificated Notes will be
available in registered form only without interest coupons. Euroclear,
Clearstream or DTC, as the case may be, will credit the account of each
subscriber or participant with the principal amount of Notes being subscribed
for by such subscriber or by or through such participant. The Global Depositary
and the U.S. Custodian are collectively referred to herein as the
"Depositaries". Notes purchased hereunder shall be delivered by or on behalf of
the Company to the Purchaser through the facilities of the Depositaries in form
for the account of the Purchaser, against payment by or on behalf of the
Purchaser of the purchase price therefor by wire transfer of United States
dollars in immediately available funds to the Trustee under the Indenture. The
Company will cause the certificates representing the Notes to be made available
for inspection by the Purchaser at least twenty-four hours' prior to the Time of
Delivery at the Closing Location (defined below). The time and date of such
delivery and payment shall be 10:00 a.m., New York time, on December 8, 2005, or
such other time and date not later than five business days after such date as
the Purchaser and the Company may agree upon in writing. Such time and date are
herein called the "Time of Delivery."

          (b) The documents to be delivered at the Time of Delivery by or on
behalf of the parties hereto pursuant to Section 8 hereof, including any
additional documents requested by the Purchaser pursuant to Section 8(s) hereof,
will be delivered at such time and date at the offices of White & Case LLP, New
York, New York (the "Closing Location"), and the Notes will be delivered to the
offices of the U.S. Custodian, all at the Time of Delivery. A meeting will be
held at the Closing Location at 10:00 a.m., on the New York Business Day next
preceding the Time of Delivery, at which meeting the final drafts of the
documents to be delivered pursuant to the preceding sentence will be available
for review by the parties hereto. For the purposes of this Section 5, "New York
Business Day" shall mean each Monday, Tuesday, Wednesday, Thursday and Friday
which is not a day on which banking institutions in New York are generally
authorized or obligated by law or executive order to close.

          (c) Beneficial interests in each Global Note will be shown on, and
transfers thereof will be effected only through, the book entry records
maintained by DTC and its direct and indirect participants.

     6.   Additional Agreements of the Company and the Guarantors.

          The Company and the Guarantors agree with the Purchaser:

unless the Purchaser shall previously have been advised thereof and shall not
reasonably have objected thereto after being furnished a copy thereof.

          (b) Promptly from time to time to take such action as the Purchaser
may reasonably request to qualify the Securities for offering and sale under the
securities laws of such jurisdictions as the Purchaser may reasonably request
and to maintain such qualification in effect in such jurisdictions for as long
as may be necessary to complete the Exempt Resales, provided that in connection
therewith the Company and the Guarantors shall not be required to qualify as a
foreign corporation or to file a general consent to service of process in any

event shall have occurred as a result of which, in the reasonable opinion of

existing, amended or supplemented would include an untrue statement of a
material fact or omit to state any material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were made
when such Offering Memorandum is delivered, not misleading, or (ii) for any
other reason, in the reasonable opinion of the Purchaser it shall be necessary
during such same period to amend or supplement the Offering Memorandum, then to
notify the Purchaser promptly, and upon the Purchaser's request to prepare and
furnish as many copies as the Purchaser may reasonably request of an amended
Offering Memorandum or a supplement to the Offering Memorandum which will
correct such statement or omission or effect such necessary amendments or
supplements and in form and substance satisfactory in the reasonable opinion of
counsel for the Purchaser. Neither the Purchaser's consent to, nor the
Purchaser's delivery of, any such amendment or supplement prior to the Time of
Delivery shall constitute a waiver of any of the conditions set forth in Section
8 hereof.

          (e) Not to offer, sell, contract to sell, grant any option to purchase
or otherwise dispose of, at any time prior to the Time of Delivery, or for a

any amendments or supplements thereto containing an untrue statement of a
material fact or omitting to state any material fact necessary to make the
statements contained therein, in the light of circumstances under which they
were made, not misleading and (ii) such other information concerning the
business and condition (financial or


                                       18



otherwise) of the Company or the Guarantors as the Purchaser may from time to
time reasonably request in writing.

          (g) To furnish at its expense, upon request, to holders and beneficial
owners of the Securities, prospective purchasers of the Securities and to
securities analysts, information satisfying the requirements of subsection

the Exchange Act.

          (h) For a period of three years from the Time of Delivery, to furnish
to the Purchaser, as soon as reasonably available, copies of all audited
financial statements, quarterly financial information and such other documents,

United States in accordance with Regulation S.

          (j) Not to offer or sell any security that will be integrated with and
negatively affect the status of the offer and sale of the Securities in the
United States as contemplated by this Agreement as transactions exempt from the

damage or liability (or any action in respect thereof), joint or several, to
which the Purchaser may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage or liability (or action in respect thereof)
arises out of or is based upon (i) any untrue statement or alleged untrue
statement of a material fact contained in the Offering Materials, or (ii) the
omission or alleged omission to state in the Offering Materials a material fact
required to be stated therein or necessary to make the statements therein not
misleading; and shall reimburse the Purchaser promptly after receipt of invoices
from the Purchaser for any legal or other expenses as reasonably incurred by the
Purchaser in connection with investigating, preparing to defend or defending
against any such loss, claim, damage, liability or action, notwithstanding the
possibility that payments for such expenses might later be held to be improper,
in which case such payments shall be promptly refunded; provided, however, that
the Company and the Guarantors shall not be liable under this Section 9(a) in
any such case to the extent, but only 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 or omission or alleged omission made in reliance
upon and in conformity with written information furnished to the Company by the
Purchaser expressly for use in the preparation of the Offering Materials as
described in paragraph (b) below; and provided further, that the foregoing
indemnity agreement is subject to the condition that, insofar as it relates to
any untrue statement, alleged untrue statement, omission or alleged omission
made in any preliminary offering memorandum which was eliminated or remedied in
the Offering Memorandum, such indemnity agreement shall not inure to the benefit
of the Purchaser (or its officers, employees or controlling Persons) if the
Company shall sustain the burden of proving and it is finally judicially


                                       26



determined that (i) the Person asserting any such loss, claim, damage, or
liability purchased the Securities from the Purchaser in reliance upon the
Preliminary Offering Memorandum but was not delivered or sent a copy of the
Offering Memorandum, at or prior to written confirmation of the sale of such
Securities to such Person, unless such failure to deliver or send the Offering
Memorandum was a result of noncompliance by the Company with Section 6 hereof
and (ii) the Purchaser, and each such officer, employee or controlling Person
would not have incurred such loss, claim, damage or liability or action had the
Offering Memorandum been delivered.

          (b) The Purchaser shall indemnify and hold harmless the Company and
each Guarantor against any loss, claim, damage or liability (or any action in
respect thereof) to which the Company or any Guarantor may become subject, under
the Securities Act or otherwise, insofar as such loss, claim, damage or
liability (or action in respect thereof) arises out of or is based upon (i) any
untrue statement or alleged untrue statement of a material fact contained in the
Offering Materials, or (ii) the omission or alleged omission to state in the
Offering Materials a material fact required to be stated therein or necessary to
make the statements therein not misleading and shall reimburse the Company or
any Guarantor promptly after receipt of invoices from the Company or such
Guarantor for any legal or other expenses reasonably incurred by the Company or
such Guarantor in connection with investigating, preparing to defend or
defending against any such loss, claim, damage, liability or action
notwithstanding the possibility that payments for such expenses might later be
held to be improper, in which case such payments shall be promptly refunded;
provided, however, that such indemnification or reimbursement shall be available
in each such case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in reliance upon and in conformity with written information furnished to the
Company by the Purchaser expressly for use therein, it being understood and
agreed that the only information furnished by the Purchaser consists of the
following information in the Offering Memorandum under the caption "Plan of
Distribution": paragraphs 5, 6, 8, 11 and 15 and the sixth sentence of paragraph
10.

          (c) Promptly after receipt by any indemnified party under subsection
(a) or (b) above 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 under such subsection, notify the indemnifying party in
writing of the claim or the commencement of that action; provided, however, that
the failure to so notify the indemnifying party shall not relieve it from any
liability which it may have under this Section 9 except to the extent it has
been prejudiced in any material respect by such failure or 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 any 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 subsection (a) or (b) above for any legal expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; except that the
indemnified party shall have the right to employ counsel to represent the
indemnified party who may be subject to liability arising out of any claim in
respect of which indemnity may be sought by the indemnified party against the


                                       27



indemnifying party under such subsection if (i) the employment thereof has been
specifically authorized by the indemnifying party in writing, (ii) the
indemnified party shall have been advised by counsel that there may be one or
more legal defenses available to the indemnified party which are different from
or additional to those available to the indemnifying party and in the reasonable
judgment of such counsel it is advisable for the indemnified party to employ
separate counsel or (iii) the indemnifying party has failed to assume the
defense of such action and employ counsel reasonably satisfactory to the
indemnified party, in which event the indemnifying party shall be liable for the
fees and expenses of such separate counsel. Notwithstanding anything in the
foregoing to the contrary, however, in no event shall the indemnifying party be
required to indemnify the indemnified party, in connection with any proceedings
or related proceedings in the same jurisdiction, for more than one legal counsel
(in addition to any local counsel) employed by the indemnified party. No
indemnifying party shall (i) without the prior written consent of the
indemnified parties (which consent shall not be unreasonably withheld or
delayed), settle or compromise or consent to the entry of any judgment with
respect to any pending or threatened claim, action, suit or proceeding in
respect of which indemnification or contribution may be sought hereunder
(whether or not the indemnified parties are actual or potential parties to such
claim or action) unless such settlement, compromise or consent includes an
unconditional release of each indemnified party from all liability arising out
of such claim, action, suit or proceeding, or (ii) 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 the consent of the indemnifying
party or if there be a final judgment of 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.

          (d) If the indemnification provided for in this Section 9 is
unavailable or insufficient to hold harmless an indemnified party under
subsection (a) or (b) above, 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 the losses, claims, damages or liabilities
referred to in subsection (a) or (b) above (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company and the
Guarantors on the one hand and the Purchaser on the other hand from the offering
of the Notes 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 Guarantors on the one hand and the Purchaser on the
other hand in connection with the statements or omissions that resulted in such
losses, claims, damages or liabilities, or actions in respect thereof, as well
as any other relevant equitable considerations. The relative benefits received
by the Company and the Guarantors on the one hand and the Purchaser on the other
hand shall be deemed to be in the same proportion as the total net proceeds from
the offering of the Notes (before deducting expenses) received by the Company
bear to the total underwriting discounts and commissions received by the
Purchaser, in each case, as set forth in Schedule A hereto. 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 information supplied by the Company or any Guarantor,
on the one hand, or the Purchaser, on the other hand, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such untrue statement or


                                       28



omission. The Company, the Guarantors and the Purchaser agree that it would not
be just and equitable if contributions pursuant to this subsection (d) were to
be determined by pro rata allocation or by any other method of allocation that
does not take into account the equitable considerations referred to in the first
sentence of this subsection (d). The amount paid by an indemnified party as a
result of the losses, claims, damages or liabilities (or actions in respect
thereof) referred to in the first sentence of this subsection (d) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating, preparing to defend or
defending against any action or claim which is the subject of this subsection
(d). Notwithstanding the provisions of this subsection (d), the Purchaser shall
not be required to contribute any amount in excess of the amount by which the
total price at which the Notes underwritten by it and distributed to investors
were offered to investors exceeds the amount of any damages that the 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 Securities Act)
shall be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation. Each party entitled to contribution agrees that
upon the service of a summons or other initial legal process upon it in any
action instituted against it in respect to which contribution may be sought, it
shall promptly give written notice of such service to the party or parties from
whom contribution may be sought, but the omission so to notify such party or
parties of any such service shall not relieve the party from whom contribution
may be sought for any obligation it may have hereunder or otherwise (except as
specifically provided in subsection (c) above).

          (e) The obligations of the Company and the Guarantors under this
Section 9 shall be in addition to any liability that the Company or any
Guarantor may otherwise have, and shall extend, upon the same terms and
conditions set forth in this Section 9, to the officers and directors of the
Purchaser and each Person, if any, who controls the Purchaser within the meaning
of the Securities Act; and the obligations of the Purchaser under this Section 9
shall be in addition to any liability that the Purchaser may otherwise have, and
shall extend, upon the same terms and conditions set forth in this Section 9, to
the officers and directors of the Company or any Guarantor and to each Person,
if any, who controls the Company or any Guarantor within the meaning of the
Securities Act.

     10.  Termination.

          This Agreement shall be subject to termination in the absolute
discretion of the Purchaser, by notice given to the Company prior to delivery of
and payment for the Securities, if at any time prior to such time (i) there
shall have been a suspension or limitation of trading in securities generally on
the New York Stock Exchange, the American Stock Exchange or NASDAQ or any
setting of minimum or maximum prices for trading thereon or there shall have
been a material disruption in the settlement of securities which, in the
judgment of the Purchaser, make it inadvisable or impractical to proceed with
the offering or delivery of the Securities; (ii) a banking moratorium shall have
been declared by either federal or New York state authorities; (iii) since the
date of this Agreement, the United States becomes engaged in hostilities or
there is an escalation of hostilities involving the United States or there is a
declaration of a national emergency or war by the United States (other than any
hostilities involving the United States,


                                       29



Iraq and Afghanistan existing on the date hereof (but without giving effect to
any escalation in any such hostilities occurring after the date hereof)) or an
act of terrorism shall have occurred which, in the judgment of the Purchaser,
make it inadvisable or impracticable to proceed with the offering or delivery of
the Securities as contemplated by the Offering Materials; or (iv) there shall
have been such 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, as to, in the judgment of the
Purchaser, make it inadvisable or impracticable to proceed with the offering or
delivery of the Securities as contemplated by the Offering Materials.

     11.  Survival of Representations, Warranties, Etc.

          The respective indemnities, agreements, representations, warranties
and other statements of the Company, the Guarantors and the Purchaser, as set
forth in this Agreement or made by or on behalf of them, respectively, pursuant
to this Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by or on behalf
of the Purchaser or any controlling Person of the Purchaser, or by the Company
or any Guarantor, or any officer or director or controlling Person of the
Company or any Guarantor and shall survive delivery of and payment for the
Securities.
