                 REPRESENTATIONS AND WARRANTIES OF THE GRANTORS

Each Grantor represents and warrants as follows:

Section 3.01. Organization; Power; Authorization.

(a) Such Grantor has good title to the Security Property purported to be pledged
by such Grantor hereby and owns its interest in such Security Property free and
clear of all Liens whatsoever except for Permitted Liens, and, subject to
Permitted Liens, has the right to mortgage, give, grant, bargain, sell,
alienate, convey, confirm, pledge, assign and hypothecate the same and to grant
a security interest therein. Such Grantor, if a Project Owner Grantor, has title
to, or possesses easements, subeasements, leases and/or licenses covering the
use of, the related Project Land sufficient to permit the construction,
ownership, maintenance and operation of the Project it purports to own and owns
the improvements related thereto. No effective financing statement or other
statement similar in effect covering all or any part of the Security Property

have been filed in favor of the Secured Party relating to this Security
Agreement.

(b) The execution, delivery and performance of this Security Agreement, and the
granting of the Lien on and security interest in the Security Property as
contemplated hereby, have been duly authorized by all requisite action on the
part of such Grantor and do not and will not (with the passage of time or giving
of notice, or both) constitute a violation or breach of or default or event of
default under any provision of such Grantor's certificate of formation,
incorporation or partnership, as the case may be, any partnership or operating
agreement of such Grantor or any other corporation, partnership or limited
liability company document of any Grantor or any agreement, indenture or
instrument to which such Grantor is a party or by which it or its Property is or
may be bound, or violate any writ, order, judgment or decree applicable to it or
any law, statute or regulation applicable to it. The execution, delivery and
performance of each other Security Document to which it is a party and the
granting of the Liens on and security interest in the Security Property as
contemplated thereby have been duly authorized by all requisite action on the
part of such Grantor and do not and will not (with the passage of time, giving
of notice, or both) constitute a violation or breach of or default or event of
default under any provision of such Grantor's certificate of formation,
incorporation or partnership, as the case may be, any partnership or operating
agreement of such Grantor or any other corporation, partnership, or limited
liability company document of such Grantor or any agreement, indenture or
instrument to which such Grantor is a party or by which it or its property is or

                                   Article IV
                                 BMC ICC Account

Section 4.01. Creation.

(a) The Illinois Grantors have established, in accordance with their respective
ICC Orders, at Merrill Lynch & Co. at its office at 200 Park Avenue, New York,
NY 10166, an account entitled ("USEB BMC ICC Account", account number 852-07129
(the "BMC ICC Account"). The BMC ICC Account will contain the following
sub-accounts:

(i) a sub-account established in accordance with the ICC Order of Countryside
(the "Countryside ICC Account");

(ii) a sub-account established in accordance with the ICC Order of Morris (the
"Morris ICC Account");

(b) Except as provided in Section 4.02(a), each ICC Account shall remain in the
exclusive possession, and under the sole dominion and control, of the Secured
Party and shall be maintained at all times in accordance with the terms of the
Loan Documents and the applicable ICC Order until the date on which all of the
Secured Obligations have been satisfied in full (except as provided in this
Security Agreement), at which time all amounts on deposit therein shall be paid
over to the applicable Illinois Grantor or other Person legally entitled
thereto; provided, however, that any payments or releases (whether in the form
of cash or otherwise) properly made by the Secured Party from any ICC Account
pursuant to Section 4.02(c), as long as such payment or release is made in
accordance with the Loan Documents, shall be released from the lien and security
interest granted hereunder and shall no longer be part of the Security Property
upon the making of such payment or release. In connection with any release of
Security Property under this subsection, the Secured Party shall, at the expense
of the Issuer, execute and deliver to the Issuer all documents that the Issuer
shall reasonably request to evidence such release. Except as provided in this
Security Agreement and any related Control Agreement, the BMC ICC Account shall
be subject to debit or withdrawal solely by the Secured Party as provided in
this Security Agreement, and no Person shall have any control over or right of
withdrawal from any ICC Account. No payments shall be made out of the BMC ICC
Account except for the purposes and on the terms provided in this Security
Agreement, the Amended Note Purchase Agreement and the ICC Orders. Each Illinois
Grantor hereby irrevocably authorizes and empowers the Secured Party, as its
attorney-in-fact, coupled with an interest, for such Illinois Grantor, to
endorse any check or any other instrument or security deposited or held in the
ICC Account related to such Illinois Grantor.

Section 4.02.     Funding of BMC ICC Account.

(a) On the Closing Date, the Illinois Grantors shall deposit into the BMC
ICC Account cash an amount equal to $8,051,991.

(b) On each Monthly Payment Date after the Closing Date, each Illinois Grantor
shall deposit or cause to be deposited into its ICC Account its Illinois
Reimbursement Minimum Amount, to the extent of available funds from the
operating cash flow received by its Pledged Illinois Project during the calendar
month most recently ended, minus the amount of payments made by such Illinois
Grantor during such calendar month with respect to (A) Operating Expenses of

                                       15

such Pledged Illinois Project and (B) interest and Principal Debt due on the
Notes.

(c) Sums in any Illinois Grantor's ICC Account shall be used to satisfy such
Illinois Grantor's obligations under its ICC Order, in accordance with
applicable laws and such Illinois Grantor's ICC Order. If no Event of Default
has occurred and is continuing, each Illinois Grantor may submit to the ICC a
reimbursement order (a "Proposed Order") with respect to such Illinois Grantor's
repayment obligations under its ICC Order, in accordance with (and not in
acceleration of) the repayment schedule contemplated by such ICC Order. Such
Illinois Grantor must obtain the Secured Party's written consent (which may not
be unreasonably withheld or delayed) to such Proposed Order prior to its
submission to the ICC. Upon approval of the Proposed Order by the ICC (in the
form in which such Proposed Order was submitted to the ICC or as revised by the
ICC, notice of which revision will be provided to the Secured Party by the
applicable Illinois Grantor), the Secured Party will release from the applicable
ICC Account any funds required to comply with such Proposed Order.

(d) The BMC ICC Account shall be managed by the Illinois Investment Advisor
subject to the Secured Party's rights hereunder. Funds in any Illinois Grantor's
ICC Account may be applied by such Illinois Grantor in its discretion on any
date (A) if all obligations of such Illinois Grantor under its ICC Order have
been fully satisfied or (B) to the extent that the sum of (x) funds in such ICC
Account and (y) the expected earnings thereon (as reasonably agreed upon by such
Illinois Grantor and the Secured Party in a written instrument signed by both
such parties) exceed the amount contemplated to be payable pursuant to such
Illinois Grantor's ICC Order with respect to the Illinois Rate Incentive already
received by such Illinois Grantor as of such date.

(e) The Grantors shall instruct each party depositing funds with the Secured
Party to identify in writing the amount of such funds, the source of such funds
and the proper account into which such funds are to be deposited.

Section 4.03.     Investment of Account Monies.

(a) So long as no Event of Default has occurred and is continuing and subject to
the last sentence of this subsection (a), the Illinois Investment Manager shall
invest any moneys held in the ICC Accounts in "Illinois Permitted Investments"
(as described in Schedule 4.03(a), which may be modified upon the Secured
Party's receipt of notice from any Illinois Grantor that such modification is
required pursuant to a final and non-appealable rule, directive or order of the
ICC ("Illinois Permitted Investments")) at the sole risk of the applicable
Illinois Grantor; provided, however, that no Illinois Investment Advisor shall
be authorized to take any action with respect to the BMC ICC Account unless the
Secured Party has (i) received notice from the Illinois Grantors of the
appointment of such Illinois Investment Advisor and (ii) consented to such
appointment. If the Secured Party receives inconsistent written instructions
from the Illinois Investment Advisor and any Illinois Grantor regarding the ICC
Account of such Illinois Grantor, the Secured Party shall follow the written
instructions of such Illinois Grantor. If an Event of Default has occurred and
is continuing, the Secured Party may, in its sole discretion, invest any moneys
held in any ICC Account in "Illinois Permitted Investments" at the sole risk of
the applicable Illinois Grantor. If (i) the Illinois Investment Advisor is no

                                       16

longer in good standing with the Securities Exchange Commission, Standard &
Poor's Ratings Group, Morningstar or brokerage firms that monitor the Illinois
Investment Advisor or (ii) investments in the BMC ICC Account are not achieving
or expected to achieve (based on the reasonable calculations of the Secured
Party) an average annual return of at least 7.00%, then (a) the Illinois
Grantors must, upon request of the Secured Party but no more frequently than
once per year, appoint a new Illinois Investment Advisor and (b) the Secured
Party may invest monies in the BMC ICC Account in investments other than
Illinois Permitted Investments.

(b) The Secured Party shall have no obligation to invest and reinvest any cash
held in the BMC ICC Account in the absence of timely and specific written
investment direction from a Responsible Officer of any Grantor or an officer of
the Illinois Investment Advisor. In no event shall the Secured Party be liable
for the selection of investments or for investment losses incurred thereon by
reason of investment performance, liquidation prior to stated maturity or
otherwise, except if the Secured Party failed to comply with the written
direction from a Responsible Officer of such Grantor or an officer of the
Illinois Investment Advisor described in this Section. The Secured Party shall
have no liability in respect of losses incurred as a result of the liquidation
of any investment prior to its stated maturity or the failure of a Responsible
Officer of any Grantor or an officer of the Illinois Investment Advisor to
provide timely written investment direction.

(c) On a quarterly basis, the Illinois Grantors shall provide to the Secured
Party performance reports with respect to the investments in the BMC ICC
Account.

                            COVENANTS OF THE GRANTORS

         Each Grantor covenants that, on and after the date of this Security
Agreement and until the Notes are paid in full and all of the Secured
Obligations are discharged:

Section 5.01.     Defense of Title.

         Each Grantor shall warrant, defend and preserve its right, title and
interest in and to the Security Property and the validity and priority of the
Lien of this Security Agreement and shall forever warrant and defend the same
against the claims of all persons whomsoever, and no Grantor shall sell or
otherwise alienate any of its interests in the Security Property except as
otherwise permitted under this Security Agreement. Each Grantor shall maintain
good and valid rights and title to its real property, including, in each case,
to the extent applicable, the land, leasehold estates, license rights and
easements constituting the Project Land, and all of its other property, free and
clear of all Liens except Permitted Liens and as otherwise provided under this
Security Agreement.

Section 5.02.     Further Assurances.

         Each Grantor shall execute and deliver any further writing, instrument
or document, in form and substance reasonably satisfactory to the Secured Party,
and take any further action as may be reasonably requested from time to time by
the Secured Party, and make all recordings and filings and take all such other
action as may be necessary or desirable under any applicable law to evidence,

                                       17

effectuate, preserve the priority of, protect and perfect the Lien on and
security interest in the Security Property, and, in addition and in furtherance
of, but not in limitation of, the foregoing, use its best efforts to comply with
any request of the Secured Party to obtain, execute, deliver or file
nondisturbance agreements, mortgagee's waivers, and such other instruments and
notices, amendments and renewals thereof, as the Secured Party shall deem

provision, in connection with any such nondisturbance agreement, mortgagee's
waiver or other instrument.

to protect the Lien on and security interest in the Security Property of such
Grantor created hereby.

(b) Each Grantor shall execute supplements to this Security Agreement and
financing statements, continuation statements and any other instruments or
documents reasonably deemed necessary or desirable by the Secured Party to

Party is authorized to record and file supplements to this Security Agreement
and financing or continuation statements to perfect, maintain or maintain the
perfection of the Secured Party's Lien on and security interest in the Security

carbon, photographic, photostatic or other reproduction of this Security
Agreement is sufficient as a financing statement where permitted by law.

reasonable expenses incident to the preparation, execution and acknowledgement
of this Security Agreement, any instrument supplemental hereto, any security
instrument with respect to the Security Property and any instrument of further
assurance, and all federal, state, county and municipal stamp taxes and other

         The Issuer shall pay promptly the fees and the reasonable costs and
expenses of the Secured Party incurred from time to time hereunder (including,

that the Secured Party may incur in the collection or enforcement of the Secured
Obligations), and shall indemnify and reimburse the Secured Party and its
officers, directors, employees, representatives and agents for all amounts

participation in the transactions contemplated hereby, including without
limitation all reasonable costs required to be associated with claims for
damages to persons or property, and reasonable attorneys' and consultants' fees

gross negligence or willful misconduct. The Issuer hereby agrees to indemnify
and hold harmless the Secured Party and its directors, officers, agents and
employees from and against any and all claims, demands, losses, penalties,
liabilities, costs, damages, injuries, and expenses, including, without
limitation, reasonable attorneys' fees and expenses, suffered or sustained by
the Secured Party, either directly or indirectly, relating to or arising out of
any Environmental Law, including, without limitation, any judgment, award,
settlement, reasonable attorneys' fees and expenses and other costs or expenses
incurred in connection with the defense of any actual or threatened action,

the Secured Party.

Section 5.05.     Notification of Litigation.

         Each Grantor shall from time to time keep the Secured Party informed of
material developments in any material action or proceeding involving it. The
Secured Party shall have the right to appear in and defend any such action or
proceeding, in the name and on behalf of such Grantor, if the Secured Party
reasonably believes the failure of such Grantor to defend such action or
proceeding could reasonably be expected to materially adversely effect the value
of the Security Property or the Lien of this Security Agreement. The Secured
Party shall also have the right to institute any action or proceeding that the
Secured Party, in its reasonable judgment, believes should be brought to protect
the value of the Security Property or the Lien of this Security Agreement. The
Issuer shall (i) indemnify, defend and hold the Secured Party harmless against
any loss or liability arising out of or related to or incurred in connection
with any action or proceeding (A) commenced by the Secured Party as provided
above, (B) to which the Secured Party is made a party or (C) in which, in the
reasonable opinion of the Secured Party, it becomes necessary to defend or
uphold the Lien of this Security Agreement or to protect the value of the
Security Property and (ii) on demand, promptly reimburse the Secured Party for
all judgments paid and expenses (including, without limitation, reasonable
attorneys' fees and appellate attorneys' fees) incurred by the Secured Party in
such action or proceeding, any such reimbursement to be an additional Secured
Obligation secured by the Security Property.

Section 5.06.     Insurance, Condemnation.

(a)Each Grantor will furnish satisfactory evidence to the Secured Party of the
renewal of each policy of insurance required by Section 7.4 of the Amended Note
Purchase Agreement, if such policy relates to the Security Property pledged by
such Grantor, at least 30 days prior to its expiration date, and will not adjust
or settle any individual claim under such insurance (except for any individual
claim for $100,000 or less) without the Secured Party's consent, which shall not
be unreasonably withheld or delayed. Each Grantor agrees that if an Event of
Default or a Default shall have occurred and be continuing and the Secured Party

                                      19

believes that the value of the Security Property is endangered, the Secured
Party may act as attorney-in-fact for such Grantor in obtaining, adjusting,
settling and canceling such insurance and receiving and endorsing any drafts
with respect to any such policy. If any Grantor shall fail to provide and pay
for any such policy at least 15 days prior to the date any such payment is due,
the Secured Party may (but shall not be required to), upon ten days' prior
written notice to such Grantor, provide or pay for the same, at such Grantor's
expense, with the amount of any such payment by the Secured Party to be
repayable by such Grantor on demand, with interest thereon due at the Default
Rate. Such amounts shall be additional Secured Obligations secured by the
Security Property.

(b)In the event of any damage, destruction, condemnation, taking or taking for
use with respect to any portion of any Pledged Project (any such event being an
"Event of Loss") in excess of $100,000 (singly or in the aggregate), the
applicable Project Owner Grantor shall notify, in writing, the Secured Party of
such Event of Loss, in accordance with Section 5.1(e) of the Amended Note
Purchase Agreement. Each Project Owner Grantor agrees that, upon the occurrence
of an Event of Loss, it will promptly pay any and all proceeds (including,
without limitation, condemnation or insurance proceeds) received by it in
respect of such Event of Loss, up to an amount equal to the then outstanding
principal amount of the Notes, plus accrued interest thereon, to the Secured
Party to be held by the Secured Party (together with all income thereon)
pursuant to this Security Agreement as part of the Security Property. The
Secured Party shall deposit all such payments received from any such Grantor or
directly from any insurer or condemning authority in a separate deposit account
(the "Insurance and Condemnation Proceeds Account"). Except as otherwise
provided in Section 5.06(f), each Project Owner Grantor shall be obligated to
repair, replace or reconstruct any Pledged Project owned by it that suffers an
Event of Loss to a condition substantially equivalent to its condition
immediately prior to such Event of Loss or to a condition of at least equivalent
value, to the extent that the insurance proceeds covering such damage or
destruction, or the amount of the award or compensation for damages recovered on
account of such taking or condemnation, shall be sufficient to pay the cost
thereof. The repair, replacement or reconstruction of such Pledged Project shall
be completed within a period of 360 days after the Event of Loss.

(c)For the purposes of this Section, a Pledged Project shall be deemed to be in
a condition substantially equivalent to its condition or value immediately prior
to an Event of Loss affecting it if, subject to gas availability, such Pledged
Project can be used effectively for substantially the same quantity and quality
of electrical generation, generation and refinement of landfill gas for
commercial sale or, as applicable, for which it was used immediately prior to
such Event of Loss, as certified in a report of the Independent Engineer
regarding the condition of such Pledged Project, in form, scope and substance
reasonably satisfactory to the Secured Party.

(d)(i) If, from time to time on or before the date that is 180 days immediately
succeeding the occurrence of an Event of Loss (or such longer period as may be
authorized by the Secured Party in its sole discretion), the Project Owner
Grantor subject to an Event of Loss shall deliver to the Secured Party a
certificate in substantially the form of Exhibit E (an "Insurance Withdrawal
Certificate"), signed by a Senior Financial Officer of such Project Owner
Grantor, certifying as to:

                                       20

(A)the amount requested to be withdrawn from the Insurance and Condemnation
Proceeds Account for such Pledged Project for the next month as reimbursement
for expenses previously incurred, presently due and payable, or to become due
and payable within one month in connection with the restoration of such Pledged
Project to a condition substantially equivalent to its condition or value
immediately prior to such Event of Loss (the "Restoration Costs");

(B)attached copies of bills or other written evidence of individual costs
describing the items purchased and/or the services rendered and all other
pertinent schedules, statements, invoices, change orders or other information;
and

(C)a  reconciliation  of all  Restoration  Costs  disbursed  through the date of
such Insurance Withdrawal  Certificate to the projected total costs of restoring
such Pledged Project to a condition substantially equivalent to its condition or
value immediately prior to such Event of Loss (the "Projected Total Restoration
Costs"),  demonstrating  that, after giving  effect to the  proposed withdrawal,
the amounts  remaining  on deposit in the  Insurance  and  Condemnation Proceeds
Account with respect to such Event of Loss are sufficient to pay the Projected
Total  Restoration  Costs of such Pledged Project (taking into account any
additional  amounts not otherwise subject to the lien of this Security Agreement
deposited by such Project Owner Grantor with the Secured  Party for the  purpose
of  effecting such restoration);

and further certifying in such certificate that (1) all the amounts of
Restoration Costs set forth in such certificate have been paid, are presently
due and payable or will be due and payable within one month, (2) none of such
amounts has been the subject of any prior payment request approved by the
Secured Party, and (3) the entire amount of the withdrawal requested in clause
(A) above will be used to pay, or to reimburse such Grantor for payment of, the
Restoration Costs set forth in the certificate, then, the Secured Party shall,
within three Business Days, transfer funds on deposit in the Insurance and
Condemnation Proceeds Account as directed by such Grantor (a written request
shall include a wire transfer instruction and all amounts disbursed hereunder
shall be wired by the Secured Party directly to the entity due such amounts).
Each Grantor hereby agrees that all funds received by it pursuant to this
Section shall be applied exclusively to the payment of, or reimbursement for,
Restoration Costs that have been properly identified in an Insurance Withdrawal
Certificate. No more than one Insurance Withdrawal Certificate shall be
delivered to the Secured Party in any single calendar month for any single
Pledged Project.

(ii) If on the date that is 180 days immediately succeeding the occurrence of an
Event of Loss,  the Pledged  Project  subject thereto has not been restored to
condition  substantially  equivalent to its condition or value immediately prior
to such Event of Loss,  then the  applicable  Project  Owner  Grantor will give
written  notice thereof to the Secured Party and the Issuer, and either (A) such
Project Owner Grantor will deposit with the Secured  Party, out of funds of such
Project Owner Grantor not held in the BMC ICC Account within thirty (30) days of
the date of such  notice, an amount determined by the Independent Engineer to be
sufficient,  when combined with the amounts on deposit in the Insurance and
Condemnation  Proceeds Account  attributable  to such Event of Loss, to complete
the  restoration of the  Pledged Project affected by  such Event of Loss  to  a
condition  substantially  equivalent to its condition or value immediately prior
to such Event of Loss, or (B) the Issuer shall prepay,  in accordance  with the
provisions of Section 6.2 of the Amended Note Purchase  Agreement,  a principal
amount of the Notes equal to the sum of the amount of insurance proceeds held by
the  Secured  Party in the  Insurance  and

                                       21

Condemnation Proceeds Account with respect to such Event of Loss,  together with
interest  accrued to the date of prepayment on the principal amount being
prepaid,  but without a prepayment premium;  provided, however, that the Secured
Party may, in its sole  discretion, extend  such restoration period beyond  180
days.  In the event that the Project Owner Grantor  elects, pursuant  to clause
(A) above,  to restore  the Pledged  Project  affected by such Event of Loss to
a condition substantially equivalent to its condition or value immediately prior
to such Event of Loss and, on the date that is 180 days immediately succeeding
the date of the notice  provided  under this  paragraph  (ii),  such  Pledged
Project has not been  restored to a condition  substantially  equivalent to its
condition or value  immediately prior to such Event of Loss, then the Issuer
shall prepay,  in accordance  with the provisions of Section 6.2 of the Amended
Note Purchase  Agreement (but without any Make Whole Amount or any other
prepayment premium), a principal amount of the Notes equal to the sum of (x) the
amount of the insurance proceeds held by the Secured Party in the Insurance and
Condemnation  Proceeds Account with respect to such Event of Loss and (y) the
amount of such insurance  proceeds  previously  disbursed from the Insurance and
Condemnation  Proceeds  Account with respect to such Event of Loss that have not
been expended for restoration.

(e)Each Grantor, immediately upon obtaining knowledge of the institution of any
proceedings for the condemnation or other taking of its Security Property or any
portion thereof in excess of $100,000 (singly or in the aggregate), or the use
thereof, shall, in accordance with Section 5.1(h) of the Amended Note Purchase
Agreement, notify, in writing, the Secured Party of the pendency of such
proceedings. The Secured Party may, but shall not be obligated to, participate
in such proceedings (including, without limitation, the making of any compromise
or settlement in connection with such proceedings), if such participation is
deemed desirable by the Secured Party, and each Grantor agrees to deliver to the
Secured Party all instruments requested by them from time to time to permit such
participation. The Secured Party is hereby irrevocably appointed as each
Grantor's attorney-in-fact, coupled with an interest, with exclusive power to
make, during the continuance of any Event of Default, any compromise or
settlement in connection with such proceedings.

(f)In the event all or substantially all of any Pledged Project is damaged,
destroyed, condemned or otherwise taken, the Issuer may, in lieu of restoring
such Pledged Project, either prepay the Notes, in accordance with Section 6.2 of
the Amended Note Purchase Agreement, or invest the proceeds from such Event of
Loss in accordance with the terms and conditions of Section 6.2(b)(iv) of the
Amended Note Purchase Agreement. In the event any portion of any Pledged Project
is subject to an Event of Loss, but less than substantially all of such Pledged
Project is affected by such Event of Loss, the applicable Project Owner Grantor
shall not be obligated to repair, replace or reconstruct any such portion if, on
or prior to the date 180 days immediately succeeding such Event of Loss, such
Project Owner Grantor, in its good faith judgment, determines that it would be
uneconomic to repair, replace or reconstruct such portion, or if the applicable
Landfill Owner exercises any right it has under any Project Document to
terminate such Project Document upon such an Event of Loss. If the applicable
Project Owner Grantor makes such determination and so certifies to the Secured
Party on or prior to the date 180 days immediately succeeding such Event of Loss
or if the Landfill Owner so terminates the Project Document, the Issuer shall
either (i), upon the

                                       22

earliest of (x) the expiration of such 180 day period, (y) the termination by
the Landfill Owner of such Project Document or (z) the receipt of proceeds, if
any, of insurance, condemnation or taking with respect to such Event of Loss,
promptly make the prepayment described above in this Section or (ii) within such
180 day period, reinvest such proceeds in accordance with the terms and
conditions of Section 6.2(b)(iv) of the Amended Note Purchase Agreement.

(g) Each Grantor, upon request by the Secured Party, shall make, execute
and deliver any and all instruments reasonably requested for the purposes of
confirming the assignment of the aforesaid insurance proceeds, awards and
compensation to the Secured Party, free and clear of any Liens of any kind or
nature whatsoever.

Section 5.07.     Maintenance of Security Property.

         Each Grantor at its own expense shall, subject to the existence of
Permitted Liens, at all times take all steps reasonably necessary and desirable
to protect its interest in the Security Property, including, without limitation,
the following:

(a) keep and maintain separate books and records relating to its interest in the
Security Property at its chief executive office in a form reasonably
satisfactory to the Secured Party;

(b) if an Event of Default has occurred and is continuing, deliver to the
Secured Party, promptly upon its request therefor, all schedules, lists,
invoices, bills of lading, documents of title, purchase orders, receipts,
chattel paper, instruments and other items relating to its interest in the
Security Property;

(c) when necessary or desirable for the perfection or maintenance of the Secured
Party's Lien on, and security interest in, the Security Property, or when
requested to do so by the Secured Party, make, stamp or record such entries or
legends on any of such Grantor's books and records relating to such Security
Property as the Secured Party shall reasonably request from time to time;

(d) defend its interest in the Security Property and defend and indemnify the
Secured Party and its officers, directors and employees against all claims,
Liens, security interests, demands and other encumbrances of third parties at
any time claiming an interest in such Security Property;

(e) keep its interest in the Security Property free of all Liens except the Lien
and security interest granted under the Security Documents and Permitted Liens;

(f) pay, promptly when due, all expenses incurred in the delivery, storage or
other handling of its interest in the Security Property; and

(g) promptly notify, in writing, the Secured Party of any Lien (other than
Permitted Liens) arising out of, or with respect to, its interest in the
Security Property.

                                       23

Section 5.08.     Compliance with Note Purchase Agreement.

         Each Grantor shall comply with each of the covenants and other
requirements of the Amended Note Purchase Agreement applicable to such Grantor.

Section 5.09.     Taxes.

(a) If any law is enacted or adopted after the date of this Security Agreement
that deducts the principal amount of the Notes from the value of the Security
Property for the purpose of taxation or that changes the laws now in force for
the taxation of deeds of trust, security instruments or debts secured thereby or
the manner of the operation of any such taxes or that otherwise imposes a tax,
either directly or indirectly, on the Notes or this Security Agreement, the
Issuer will pay such tax, with interest and penalties thereon, if any, provided,
however, that in no instance shall the Issuer be obligated to pay any state,
local or federal income taxes owed by the Secured Party except as specifically
provided in the Amended Note Purchase Agreement.

(b) No Grantor will claim or demand or be entitled to any credit or credits on
account of the Notes for any part of the taxes against the Security Property or
any part thereof and no deduction shall otherwise be made or claimed from the
taxable value of the Security Property, or any part thereof, by reason of this
Security Agreement or the Notes.

(c) If at any time the United States of America, any State thereof or any
subdivision of any such State shall require revenue or other stamps to be
affixed to the Notes or this Security Agreement, or impose any other tax or
charge on the same, the Issuer will pay for the same, with interest and
penalties thereon, if any, provided, however, that in no instance shall the
Issuer be obligated to pay any local, state, provincial or federal income taxes
of the Secured Party.

Section 5.10.     Project Documents.

(a) Each Grantor will, within the applicable grace periods, at all times keep,
observe and perform or cause to be kept, observed or performed all the material
terms, covenants and agreements of the Project Documents to which it is a party
and, without limiting the generality of the foregoing, will pay all amounts
payable by it under such Project Documents subject to standards of commercial
reasonableness. Each Grantor will take any and all such actions as may be
necessary promptly to enforce its rights and to collect any and all sums due it
under the Project Documents to which it is a party. Each Grantor will do or
cause to be done all things reasonably necessary to preserve and keep unimpaired
its rights under the Project Documents to which it is a party and to prevent any
termination, surrender, cancellation, forfeiture or impairment of any thereof
and to prevent any material default under any of such Project Documents for
terminations of the Project Documents by the counterparties thereto as of right.
Each Grantor will, promptly upon the receipt thereof, deliver to the Secured
Party copies of all Material notices, demands or declarations at any time
received by such Grantor from counterparties to any of the Project Documents to
which it is a party.

(b) Should any Grantor fail punctually to keep, observe and perform any of the
material terms, covenants and agreements of this Security Agreement or the
Project Documents to which it is a party, the Secured Party may, but shall not
be obligated, upon ten days' written notice to such Grantor, to effect such
performance on behalf of such Grantor and the Grantors shall, on demand,

                                       24

reimburse the Secured Party for any amounts expended by it to effect such
performance, with interest thereon at the Default Rate, such amounts to be
additional Secured Obligations secured by the Security Property.

(c) At the written request of the Secured Party, each Grantor shall exercise its
right, if any, to cure any default of any Gasco under any agreement between such
Gasco and any Landfill Owner that grants to such Gasco the right to recover,
refine, process, transmit and otherwise deal with landfill gas and constituent
products from the landfill that is the subject of any Project Document,
including, without limitation, the payment of any amounts payable by such Gasco
under such agreement and not paid when due. Should any Grantor fail to cure such
default within ten (10) days after written request therefor by the Secured
Party, the Secured Party may, but shall not be obligated to, effect such cure on
behalf of such Grantor and such Grantor shall, on demand, reimburse the Secured
Party for any amounts expended by it to effect such performance, with interest
thereon at the Default Rate, such reimbursement to be additional Secured
Obligations secured by the Security Property.

(d) No Grantor will receive or collect any payments under the Project Documents
to which it is a party in advance of the time when the same become due and
payable thereunder without the prior written consent of the Secured Party (which
may not unreasonably be withheld or delayed).

(e) No Grantor will cancel or terminate any of the Project Documents to which it
is a party or permit any cancellation or termination of any thereof (except for
terminations in the sole discretion of such Grantor's counterparty to any such
Project Document) or amend, compromise or modify any of the material terms or
provisions of any such Project Document or waive any term or provision of any
thereof (except for waivers not material to the security for the Secured
Obligations given in the day-to-day administration of such Project Documents) or
enter into any Material agreement or commitment provided for in such Project
Documents without the prior written consent of the Secured Party, which shall
not be unreasonably withheld or delayed.

(f) No Grantor shall make any election or give any consent or approval under any
of the Project Documents to which it is a party, if such consent or approval is
material to the preservation of the Security Property pledged by it hereunder,
without the prior written consent of the Secured Party, which shall not be
unreasonably withheld or delayed.

(g) Each Grantor shall, in accordance with Section 5.1(g) of the Amended Note
Purchase Agreement, give the Secured Party written notice immediately upon any
party to a Project Document requesting an arbitration proceeding under and
pursuant to the provisions of such Project Document, which arbitration
proceeding affects any Grantor, any of its Pledged Projects or any Security
Property pledged by it hereunder, the value of which exceeds $250,000 (singly or
in the aggregate). The Secured Party shall have the right, but not the
obligation, to intervene and participate in any such proceeding, and each
Grantor agrees to confer with the Secured Party, to the extent the Secured Party
shall deem necessary. No Grantor shall compromise any such arbitration
proceeding without the prior written consent of the Secured Party (which may not
unreasonably be withheld or delayed) and if, at the time any such proceeding
shall be commenced, an Event of Default has occurred and is continuing, the
Secured Party shall have the exclusive right to appoint the arbitrator on behalf
of such Grantor and to control the conduct of the proceeding.

                                       25

(h) Each Grantor shall execute and deliver, upon the request of the Secured
Party, such instruments as the Secured Party may reasonably deem useful or
required to permit the Secured Party to cure any default under any Project
Document to which such Grantor is a party or permit the Secured Party to take
such actions as the Secured Party may deem necessary to remedy the matter in
default and preserve the interest of the Secured Party in such Project Document.

(i) No Grantor will enter into any agreement, other than the Power Purchase
Agreements, covering the sale of electricity or refined landfill gas from any of
its Pledged Projects without the prior written consent of the Secured Party
(which may not unreasonably be withheld or delayed). Each Grantor shall take
such action as may be required effectively to subject its interest in any such
agreement to the Lien and security interest of this Security Agreement.

Section 5.11.     Applicable Permits.

         Each Project Owner Grantor will duly obtain when needed, and thereafter
maintain in effect as long as legally required, all Applicable Permits, except
where the failure to obtain or maintain an Applicable Permit could not
reasonably be expected to have a Material Adverse Effect.

Section 5.12.     Delivery of Security Property.

         Each Grantor shall deliver all certificates or instruments representing
or evidencing Security Property pledged by it hereunder to, and all such
certificates or instruments shall be held by or on behalf of, the Secured Party,
and all such certificates or instruments shall be in suitable form for transfer
by delivery, or shall be accompanied by duly executed instruments of transfer or
assignment in blank, all in form and substance satisfactory to the Secured
Party, and each Grantor and its subsidiaries will maintain at all times a
register at its chief executive office in which shall be evidenced the security
interest of the Secured Party in all of the Security Property pledged by such
Grantor hereunder and not evidenced by physical certificates issued by or its
subsidiaries. For the better perfection of the Secured Party's rights in and to
the Security Property, each Grantor shall forthwith, upon the occurrence and
continuation of a Event of Default and upon the request of the Secured Party,
cause such Security Property pledged by it hereunder to be registered in the
name of the Secured Party or such of its nominees as the Secured Party shall
direct, provided, however, that,

(a)      so long as no Event of Default has occurred and is continuing,

(i)      each Grantor shall be entitled to exercise any and all voting and other
         consensual rights pertaining to the Security Property pledged by it
         hereunder or any part thereof for any purpose not inconsistent with the
         terms of this Security Agreement or the other Loan Documents; provided,
         however, that such Grantor shall not exercise or refrain from
         exercising any such right if such action would have a Material Adverse
         Effect,

                                       26

(ii)     each Grantor shall be entitled to receive and retain any and all
         dividends, partnership draws, other distributions and interest paid in
         respect of the Security Property pledged by it hereunder (which, upon
         receipt by any Grantor shall no longer constitute Security Property),
         subject to the terms of Section 8.6 of the Amended Note Purchase
         Agreement,

(iii)    the Secured Party shall execute and deliver (or cause to be executed
         and delivered) to each Grantor all such proxies and other instruments
         as such Grantor may reasonably request for the purpose of enabling such
         Grantor to exercise the voting and other rights that it is entitled to
         exercise pursuant to paragraph (i) above and to receive the dividends,
         partnership draws, other distributions and interest that it is
         authorized to receive and retain pursuant to paragraph (ii) above,

(b)      upon the occurrence and during the continuance of an Event of Default,

(i)      All rights of each Grantor (A) to exercise or refrain from exercising
         the voting and other consensual rights that it would otherwise be
         entitled to exercise pursuant to Section 5.12(a)(i) shall, upon notice
         to such Grantor by the Secured Party, cease and (B) to receive the
         dividends, partnership draws, other distributions, and interest
         payments that it would otherwise be authorized to receive and retain
         pursuant to Section 5.12(a)(ii) shall automatically cease, and all such
         rights shall thereupon become vested in the Secured Party, which shall
         thereupon have the sole right to exercise or refrain from exercising
         such voting and other consensual rights and to receive and hold as
         Security Property such dividends, partnership draws, other
         distributions and interest payments.

(ii)     All dividends, partnership draws, other distributions and interest
         payments that are received by any Grantor contrary to the provisions of
         paragraph (i) above shall be received in trust for the benefit of the
         Secured Party, shall be segregated from other funds of such Grantor and
         shall be forthwith paid over to the Secured Party as Security Property
         in the same form as so received (with any necessary endorsement).

(c)      Each Grantor shall (i) cause each issuer of the Pledged Interests and
         the Pledged Debt not to issue any stock, other securities or interests
         or other evidence of Indebtedness in addition to or in substitution for
         the Pledged Interests and Pledged Debt issued by such issuer, except as
         permitted under the Amended Note Purchase Agreement, and (ii) pledge
         hereunder, immediately upon its acquisition (directly or indirectly)
         thereof, any and all additional shares of stock, other securities or
         interests or other evidence of indebtedness.

(d)      To the extent that any of the Security Property not evidenced by
         physical certificates constitutes uncertificated securities under
         Article 8 of the UCC and is issued by any Grantor, each Grantor that
         has issued such Security Property agrees to comply with instructions
         originated by the Secured Party with respect to such Security Property
         without further consent by the registered owners of such Security
         Property.

Section 5.13.     No Secured Party Liability.

         Each Grantor acknowledges that the Secured Party shall not have any
liability, obligation or responsibility whatsoever to such Grantor with respect

                                       27

to the operation of any of its Pledged Projects, unless the Secured Party shall
take possession of any such Pledged Project, in which case the Secured Party
shall have no liability, obligation or responsibility whatsoever to any Grantor
in connection with the operation of such Pledged Project, except for any
liability arising from the breach of the Loan Documents or any applicable law,
negligence, willful misconduct or bad faith of the Secured Party. Moreover, each
Grantor acknowledges that the Secured Party shall not be obligated to inspect
any Pledged Project, nor be liable for any failure to protect or insure any
Pledged Project pledged hereunder, or for the payment of costs of labor,
materials or services supplied for the operation of any such Pledged Project, or
for the performance of any obligation of any Grantor whatsoever, except for any
liability arising from the breach of the Loan Documents, negligence, willful
misconduct or bad faith of the Secured Party.

                                   Article VI
                                    REMEDIES

Section 6.01.     Remedies on Default.

(a)      If an Event of Default shall have occurred and be continuing, the
         Secured Party may, in addition to any other rights or remedies it may
         have as a Secured Party under the laws of the State of New York, the
         UCC or other applicable law, and in addition to the rights and remedies
         provided in Section 10.02 of the Amended Note Purchase Agreement, take
         any one or more of the following remedial steps, subject to the
         provisions of applicable law:

(i)      realize upon and take possession of any Security Property, and, if and
         to the extent any of the Security Property shall not be in the
         possession or under the control of the Secured Party, the Secured Party
         may require the Grantors to assemble or package the Security Property
         and make it available to the Secured Party at a place to be designated
         by the Secured Party; or

(ii)     sell, assign, lease or otherwise dispose of the Security Property in
         whole or in part at public or private sale upon terms and conditions
         established by the Secured Party; or

(iii)    notify any and all parties to any of the contracts and agreements that
         constitute Security Property that the Secured Party has exercised its
         rights hereunder and that (to the extent not already done so) all
         payments then or thereafter owing to any Grantor are to be made
         directly to the Secured Party.

(b)      In addition to the remedies set forth above, the Secured Party may
         exercise its rights under the other Loan Documents.

(c)      Should the Secured Party elect to cause any of the Security Property to
         be disposed of as personal property as permitted by the terms hereof,
         it may dispose of any part thereof in any manner now or hereafter
         permitted by Article 9 of the UCC or in accordance with any other
         remedy provided by law, subject to the provisions of this Security
         Agreement. Each Grantor and the Secured Party agree that twenty days'
         notice of any public or private sale or other disposition of personal

                                       28

         property shall be reasonable notice thereof and such sale shall be at
         such location as the Secured Party shall designate in such notice. Any
         notice given with respect to any such sale shall be given in accordance
         with Section 9-611 of the UCC, or any successor provision, as in effect
         from time to time. The Secured Party need not give such notice with
         respect to Security Property that is perishable or threatens to decline
         speedily in value or is of a type customarily sold on a recognized
         market. At any public sale or disposition of the Security Property, the
         Secured Party shall have the right to bid and become the purchaser.
         Each Grantor hereby waives any right to require the Security Property
         to be disposed of seriatim or in any particular order or sequence.

(d)      Upon any taking of possession of any Pledged Project pursuant to this
         Security Agreement, the Secured Party may, from time to time at the
         expense of the applicable Project Owner Grantor, make all such repairs,
         replacements, alterations, additions and improvements to such Pledged
         Project as the Secured Party may deem proper. In any such case, the
         Secured Party shall have the right to manage and control such Pledged
         Project and to carry on the business and to exercise all rights and
         powers of such Project Owner Grantor with respect thereto as the
         Secured Party shall deem best, including the right to enter into any
         and all such agreements with respect to the leasing and/or operation of
         such Pledged Project or any part thereof as the Secured Party may see
         fit. The Secured Party shall be entitled to collect and receive all
         rents, issues, profits, fees, revenues and other income of the same and
         every part thereof. Such rents, issues, profits, fees, revenues and
         other income shall be applied to pay the actual incurred expenses of
         constructing, holding and operating such Pledged Project, of all
         maintenance, repairs, replacements, alterations, additions and
         improvements thereto, and of conducting the business of the applicable
         Project Owner Grantor with respect thereto, to make all payments that
         the Secured Party may be required to or may elect to make, if any, for
         taxes, assessments, insurance and other charges upon such Pledged
         Project or any part thereof, and to make all other payments that the
         Secured Party may be required or authorized to make under any provision
         of this Security Agreement (including reasonable legal costs and
         attorneys' fees). The remainder of such rents, issues, profits, fees,
         revenues and other income, if any, shall be applied in accordance with
         Section 10.03 of the Amended Note Purchase Agreement. Without limiting
         the generality of the foregoing, the Secured Party shall have the right
         to apply for and have a receiver appointed by a court of competent
         jurisdiction in any action taken by the Secured Party to enforce its
         rights and remedies hereunder in order to manage, protect and preserve
         such Pledged Project and continue the operation of the business of the
         applicable Project Owner Grantor and to collect all revenues and
         profits thereof and apply the same to the payment of all actual
         incurred expenses and other charges of such receivership including the
         compensation as aforesaid until a sale or other disposition of such
         Pledged Project shall be finally made and consummated, provided,
         however, that in no instance shall such revenues and profits thereof be
         applied to pay any local, state, provincial or federal income taxes of
         the Secured Party.

(e)      In order to facilitate the exercise by the Secured Party of the rights
         and remedies set forth in this Article, each Grantor does hereby
         irrevocably appoint the Secured Party its true and lawful
         attorney-in-fact with full power of substitution, for it and in its
         name, place and stead, to ask, demand, collect, receive, receipt for,
         sue for, compound and give acquittance for any and all of the Security
         Property pledged by it hereunder with full power to settle, adjust or
         compromise any claim hereunder or under such Security Property as fully
         as such Grantor could itself do, and to endorse the name of such

                                       29

         Grantor on all commercial paper given in payment or in part payment
         thereof, and in its discretion to file any claim or take any other
         action or commence any other proceedings, either in its own name or in
         the name of such Grantor, or otherwise, which the Secured Party may
         deem necessary or appropriate to collect any and all sums which may be
         or become due or payable hereunder or under such Security Property, or
         that may be necessary or appropriate to protect and preserve the right,
         title and interest of the Secured Party in and to such sums and the
         security intended to be afforded hereby and thereby. In addition, each
         Grantor hereby appoints the Secured Party or any of its officers and
         agents, or any other person whom the Secured Party may designate, as
         attorney-in-fact for such Grantor, at such Grantor's sole cost and
         expense, to exercise all or any of the following powers, which, being
         coupled with an interest, shall be irrevocable, shall continue until
         all Obligations have been paid in full and shall be in addition to any
         other rights and remedies that such Grantor may have: (i) to remove
         from any premises where they may be located any and all documents,
         instruments, files and records relating to the Security Property
         pledged by it hereunder and any receptacles and cabinets containing the
         same, and at such Grantor's sole cost and expense, to use such of the
         personnel, supplies and space of such Grantor at its place of business
         as may be necessary properly to administer and control the Security
         Property or the collections and realizations thereon; (ii) to take or
         bring, in such Grantor's name or in the name of the Secured Party, all
         steps, actions, suits or proceedings deemed by the Secured Party
         necessary or desirable to effect collection of or to realize upon the
         Security Property pledged by it hereunder; and (iii) to endorse the
         name of such Grantor or any of such Grantor's officers or agents upon
         any notes, checks, drafts, money orders, or other instruments of
         payment (including payments payable under any policy of insurance upon
         any Security Property pledged by it hereunder) that may come into
         possession of the Secured Party in full or in part payment of any
         amounts owed to the Secured Party.

(f)      Notwithstanding any provision to the contrary contained in any Loan
         Document, the Secured Party may not take any action against any Grantor
         pursuant to this Section 6.01 unless and until (i) the Secured Party
         has provided notice to the Grantors of an Event of Default and (ii) a
         period of ten days has elapsed after such notice has been received by
         the Grantors (provided, however, that the requirements of this sentence
         need not be met if an Event of Default described in Section 10.01(h)
         has occurred).

                                  Article VII
                          CONCERNING THE SECURED PARTY

Section 7.01.     Duties; Conduct; Protections.

(a)      Except during the continuance of an Event of Default:

(i)      the Secured Party undertakes to perform such duties and only such
         duties as are specifically set forth in this Security Agreement, and no
         implied covenants or obligations shall be read into this Security
         Agreement against the Secured Party; and

(ii)     in the absence of bad faith on its part, the Secured Party may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, including the accuracy
         of all sums and calculations, upon certificates or opinions furnished
         to the Secured Party and conforming to the requirements of this
         Security Agreement.

                                       30

(b)      If an Event of Default has occurred and is continuing, the Secured
         Party shall exercise such of the rights and powers vested in it by this
         Security Agreement, and use the same degree of care and skill in their
         exercise, as a prudent individual would exercise or use under the
         circumstances in the conduct of his or her own affairs.

(c)      The Secured Party may perform any of the duties or exercise any of the
         powers provided for in this Security Agreement either directly or
         through its attorneys, agents, custodians or nominees appointed with
         due care and duly authorized in writing.

(d)      The Secured Party may consult with counsel, appraisers, engineers,
         accountants, and other skilled persons to be selected by it, at the
         expense of the Grantors, and the written advice of any thereof shall be
         full and complete authorization and protection in respect of any action
         taken, suffered or omitted by it under this Security Agreement if
         relied upon reasonably and in good faith.

(e)      The Secured Party shall not be answerable or accountable under any
         circumstances except for its own willful misconduct or negligence. The
         negligence or willful misconduct of any taxing authority or any other
         Person may not be imputed to the Secured Party. No provision of this
         Security Agreement shall be construed to relieve the Secured Party from
         liability for its own negligent action, its own negligent failure to
         act or its own willful misconduct, except that:

(i)      this subsection shall not be construed to limit the effect of
         subsection (a) above;

(ii)     the Secured Party shall not be liable to any Person for any error of
         judgment made in good faith unless it shall be proved that the Secured
         Party was negligent in ascertaining or in failing to ascertain the
         pertinent facts;

(iii)    the Secured Party shall be entitled to rely conclusively upon any note,
         notice, resolution, request, consent, direction, certificate,
         affidavit, letter, telephone communication, telegram, teletype,
         message, statement, order or other document reasonably believed by the
         Secured Party to be genuine and correct and to have been signed or sent
         by a Responsible Officer of any Grantor; and

(iv)     no provision of this Security Agreement shall require the Secured Party
         to expend or risk its own funds or otherwise incur any financial
         liability in the performance of any of its duties hereunder, or in the
         exercise of any of its rights or powers, if it shall have reasonable
         grounds for believing that repayment of such funds or indemnity
         satisfactory to it against such risk or liability is not reasonably
         assured to it.

(f)      Subject to subsections (a) and (b) above and as required by law, the
         Secured Party shall have no duty:

(i)      to obtain or request further assurances pursuant to Section 5.02
         hereof;

(ii)     to file, record or deposit this Security Agreement or any other
         document contemplated hereby, or to maintain any such filing, recording
         or deposit or to refile, re-record or redeposit any such document;

                                       31

(iii)    to obtain or request insurance of any item of Security Property or to
         maintain any such insurance or to consent to any adjustment or
         settlement;

(iv)     to consent to any amendment, termination, waiver or modification of any
         Project Document, except that the Secured Party shall not withhold its
         consent unreasonably;

(v)      to effect any release of any item of the Security Property or to grant
         any other remedy to any Grantor or any other Person;

(vi)     to maintain or mark any item of the Security Property or any part
         thereof;

(vii)    to pay or discharge any tax, assessment or other governmental charge or
         any Lien of any kind owing with respect to or assessed against any item
         of the Security Property;

(viii)   to confirm, verify, investigate or inquire into the failure to receive
         any report or financial statement of any Grantor;

(ix)     to inspect any item of the Security Property;

(x)      to instruct any Grantor concerning the keeping and maintenance of books
         and records;

(xi)     to confirm or recalculate any calculation furnished to it; or

(xii)    to confirm the accuracy of any disbursement request submitted to it.

(g)      The Secured Party shall not be responsible for the correctness of any
         recitals or statements in this Security Agreement or in any schedule
         attached hereto.

(h)      The Secured Party makes no representation as to the value or validity
         of the Security Property.

(i)      The Secured Party shall be under no obligation with respect to the
         application of any moneys paid to it except as may be expressly
         provided herein.

Section 7.02.     Special Rights.

         Notwithstanding anything contained elsewhere in this Security
Agreement, the Secured Party shall have the right, but shall not be required, to
demand the subjection of any after acquired property to the Lien of this
Security Agreement, or any other action whatsoever (other than a withdrawal of
cash) within the purview hereof, any showings, certificates, opinions,
appraisals or other information by or from any Grantor reasonably deemed
necessary or appropriate by it in order to maintain and preserve the security
interest granted hereby.

                                       32

Section 7.03.     Release of Certain Security Property.

         Notwithstanding any provision hereof to the contrary, the Secured Party
shall provide to the Grantors a partial release of the Lien created hereunder on
any Pledged Illinois Project if the Landfill Owner for such Pledged Illinois
Project pays to the Secured Party an amount equal to the then fair market value
of such Pledged Illinois Project, such fair market value to be determined and
certified in writing to the Secured Party by the Independent Engineer. The
Issuer will apply an amount equal to such fair market value or buyout amount to
prepay the Notes in accordance with Section 6.2 of the Amended Note Purchase
Agreement. Upon such payment to any Illinois Grantor by the applicable Landfill
Owner, such Illinois Grantor may apply any funds held in the ICC Account
relating to its Pledged Illinois Project (if the reimbursement obligation under
the Illinois Rate Incentive is not assumed by the purchaser of such Pledged
Illinois Project) to satisfy such Pledged Illinois Project's reimbursement
obligation under the Illinois Rate Incentive in such manner as the ICC may
require in connection with any such transaction described above.

                                  Article VIII
                        CONSENTS TO ASSIGNMENT AND PLEDGE

Section 8.01.     Consent to Pledge and Assignment.

(a) Each Grantor that holds any Pledged Interest in any Person hereby
acknowledges and consents to the pledge and assignment by each other Grantor of
its Pledged Interest in such Person pursuant to this Security Agreement as
collateral security for all the Secured Obligations.

(b) Each Grantor that is a party to a Project Document with one or more other
Loan Parties (each an "Obligor") hereby (i) acknowledges and consents to the
pledge and assignment by each such Obligor to the Secured Party, pursuant to
this Security Agreement, of all right, title and interest of such Obligor in, to
and under (but not its obligations, liabilities or duties with respect to) each
such Project Document as security for the Secured Obligations and (ii) confirms
to the Secured Party that all representations, warranties, indemnities and
agreements of such Grantor under such Project Document shall inure to the
benefit of, and shall be enforceable by, the Secured Party to the same extent as
if originally named in such Project Document.

(c) Each Grantor hereby grants to the Secured Party all consents, waivers and
approvals required from such Grantor under any Project Document, applicable
statute, rule, regulation or ordinance, or otherwise, in order for (i) the
Issuer to issue the Notes and enter into the Loan Documents and (ii) the Secured
Party to exercise any right or remedy under any Loan Document.

Section 8.02.     Representations and Warranties of Grantors.

         Each Grantor represents and warrants as follows:

(a) Such Grantor affirms that it has no notice of any effective assignment
relative to the right, title and interest of any Obligor in, to and under (i)
the Project Documents to which such Grantor is a party and (ii) the Pledged
Interests in Persons in which such Grantor also owns an interest, other than the
pledge and assignment to the Secured Party under this Security Agreement and the
Other Security Agreement.

                                       33

(b) There is not now, and, after giving effect to the pledge and assignment by
the Grantors to the Secured Party of the Project Documents hereunder, there will
not be, any event or condition (a "Termination Event") which would, either
immediately or with the passage of time or giving of notice, or both, constitute
a default under any Project Document and/or enable any party thereto to
terminate or suspend its obligations under any Project Document, and there are
no claims or rights of set-off pending by any party to any Project Document.

Section 8.03.     Agreements of Grantors.

(a) Each Grantor agrees that it will not terminate or suspend its obligations,
or otherwise exercise any remedies, under any Project Document or with respect
to any Pledged Interest resulting from a Termination Event relating to any
Obligor without first giving the Secured Party the notice and opportunity to
cure provided for in subsection (c) below.

(b) Each Grantor agrees that at the time any notice of a Termination Event or
any other notice pursuant to the provisions of any Project Document or with
respect to any Pledged Interest shall be given to any Obligor, such Grantor
shall at the same time give a duplicate of such notice to the Secured Party.
Without limiting the generality of the foregoing, if a Termination Event shall
occur relating to an Obligor, and any corresponding Grantor shall desire to
exercise its remedies under the applicable Project Document as provided in
subsection (a) above with respect to such Termination Event, such Grantor shall
promptly give notice to the Secured Party, at the address set forth below, of
such Termination Event, specifying in such notice all then existing Termination
Events of which it has knowledge, such notice to be delivered to the Secured
Party by hand delivery or by an overnight courier of recognized national
standing and to be confirmed by telephone, if possible with reasonable effort.
The Secured Party may, within 30 days after the receipt by it of such notice
(which shall include such Grantor's address), deliver to such Grantor a written
notice stating that it has elected to cure such Termination Event, together with
a written statement of the Secured Party that it will promptly commence to cure
all Termination Events relating to such Obligor that are susceptible of being
cured by the Secured Party, and that it will, during the cure period provided in
subsection (c) below, diligently attempt in good faith to complete the curing
of, to the reasonable satisfaction of such Grantor, all such Termination Events;
provided, however, that nothing set forth herein shall be deemed to create any
obligation of the Secured Party to cure any Termination Event.

(c) The Secured Party shall have a period of, (i) in the case of Termination
Events relating to an Obligor arising from monetary defaults, 90 days, and (ii)
in the case the case of all other Termination Events relating to an Obligor, 180
days (such period being hereinafter referred to as the "Cure Period") after the
delivery of the notice by the Secured Party referred to in subsection (b) above
in which to cure such Termination Events. In the event any Termination Event
described in clause (ii) shall be incurable by the Secured Party within the Cure
Period, the applicable Grantor shall not exercise any remedies under the
applicable Project Document if the Secured Party shall, within the Cure Period,
initiate action to cure such Termination Event and proceed diligently to the
curing thereof. Any curing of any Termination Event under any Project Document
shall not be construed as an assumption by the Secured Party of any obligations,
covenants or agreements of the Obligor under such Project Document. If the

                                       34

Secured Party is required to obtain the approval of any court or to take any
other action in any bankruptcy or other proceeding before exercising its rights
under this subsection (c), the Cure Period shall be extended by the period
required to obtain such approval or take such other action.

Section 8.04.     Rejection of Project Documents.

         In the event that any Project Document between two or more Grantors is
rejected under 11 U.S.C. Section 365, or successor legislation, and (i) no
amounts payable thereunder shall be due and payable to any Grantor at the time
of such rejection, (ii) the Secured Party shall have arranged for the curing of
any default under such Project Document susceptible of being corrected by the
Secured Party and (iii) such Project Document shall have been terminated
pursuant to the terms thereof by reason of a rejection by the applicable Obligor
or a trustee in bankruptcy under 11 U.S.C. Section 365, or successor
legislation, then the applicable Grantor shall, if requested by the Secured
Party within thirty (30) days after such rejection, execute and deliver a new
Project Document of like tenor to be in effect for the remainder of the term of
the rejected Project Document, and with substantially the same terms as those
contained therein.

Section 8.05.     Performance by Secured Party.

         The Secured Party shall not have any obligation or liability to any
Grantor for the performance of any obligations under any Project Document or
with respect to any Pledged Interest unless and until the Secured Party shall
have notified such Grantor in writing that it intends to assume the obligations
imposed upon the Obligor(s) by the Project Document and receive the benefits
thereunder. In the event that the Secured Party succeeds to the interest of an
Obligor under a Project Document by reason of the exercise of the Secured
Party's rights under this Security Agreement, such Grantor agrees that it will
accept performance by the Secured Party or its successors or assigns or
designees of the obligations of the Obligor(s) under and in accordance with such
Project Document notwithstanding any restrictions set forth in such Project
Document on the assignability of each such Obligor's rights. If the Secured
Party assumes the rights and/or obligations of any Obligor under any Project
Document, the Secured Party shall have the right to assign such Project Document
to a party that assumes the obligations of the Obligor(s) thereunder or with
respect thereto (notwithstanding any limitation or restriction thereon set forth
in any Project Document) and upon such assignment or transfer, the Secured Party
shall be released from any liability under such Project Document from and after
the date of such assignment or transfer and thereafter such Project Document
shall remain in full force and effect for the benefit of such assignee. Upon any
such assignment of a Project Document by the Secured Party, such assignee shall
have the right to terminate the Agreement by giving written notice thereof to
the applicable Grantor(s).

Section 8.06.     Waivers.

(a) Each Grantor (i) waives presentment, protest, notice of protest, notice of
dishonor, notice of nonpayment, notice of acceptance of this Security Agreement,
notice of loans made, credit extended, Security Property received or delivered
or other action taken in reliance hereon and (ii) assents to any extension or
postponement of the time of payment or any other indulgence, to any
substitution, exchange or release of the Security Property, to the addition or
release of any party or Person primarily or secondarily liable, to the

                                       35

acceptance of partial payments thereon and the settlement, compromising or
adjusting of any thereof, all in such manner and at such time or times as the
Secured Party may deem advisable. In each of the foregoing instances, the
Secured Party shall be deemed to believe in good faith that the action in
question is commercially reasonable.

(b) Any delay, omission or failure by the Secured Party to insist upon the
strict performance by any Grantor of any of the covenants, conditions and
agreements herein or to exercise any right or remedy available to it upon the
occurrence and continuance of an Event of Default shall not impair any such
right or remedy or be considered or taken as a waiver or relinquishment of the
future right to insist upon and to enforce, by injunction or other appropriate
legal or equitable remedy, strict compliance by each Grantor with all such
covenants, conditions and agreements or of the right to exercise any such rights
or remedies if such default by such Grantor be continued or repeated. Regardless
of consideration and without notice to or consent of any of the holders of any
subordinate Lien on the Security Property, the Secured Party may (i) release any
part of the Security Property, (ii) release the obligations of any Person
primarily or contingently liable for the Secured Obligations, or (iii) extend
the time for payment under, or otherwise modify the terms of, this Security
Agreement, and no such release, extension or modification shall impair or affect
the Lien of this Security Agreement, or the priority of such Liens over any
subordinate Lien. No Grantor shall be relieved of any liability by reason of (A)
any such release, extension or modification, (B) the failure of the Secured
Party to comply with any request of any or all of the Grantors to foreclose this
Security Agreement or exercise any other remedy available under this Security
Agreement, or (C) any agreement or stipulation between any subsequent owner of
the Security Property and the Secured Party extending the time of payment or
modifying the terms of this Security Agreement.

Section 8.07.     Unconditional Nature of Secured Obligations.

         The obligations and liabilities of the Grantors hereunder are absolute
and unconditional and shall remain in full force and effect until the
satisfaction of all of the Secured Obligations, without regard to any event,
circumstance or condition that might constitute a legal or equitable defense or
discharge of any Grantor or that might in any way limit recourse against any
Grantor, including without limitation: (i) any waiver, consent or indulgence by
the Secured Party or any exercise or non-exercise of any right, power or remedy
against any Grantor; (ii) any limitation or cessation of any Grantor's liability
under any Loan Document, including without limitation any invalidity,
unenforceability or impaired liability resulting from any Grantor's lack of
capacity, power and/or authority to enter into any Loan Document or from the
execution and delivery of any Loan Document by any person acting for any Grantor
without or in excess of authority; (iii) any failure to join any Grantor in an
action to enforce any Loan Document; or (iv) any Grantor's insolvency,
bankruptcy, reorganization, dissolution, liquidation or any similar action with
respect to any Grantor.

Forecast for May shows that Orbitz will be short by 1,000,000 segments in meeting its Worldspan Segment Obligation, and 14,000,000 Segments were processed using Network Services by all carriers during
Feb., Mar. and Apr., and 6,000,000 Supplier Link Segments were processed by Airline during Feb., Mar. and Apr., then Orbitz could Throttle Airline by 42.86% (6/14) of 1,000,000 Segments
or a total of 428,600 Segments. 

        1.40    "Supplier Link Ticket" means a Ticket booked and issued for
transportation on Airline's flights, Codeshare flights or flights sold under Airline's designator code through the Network Services. All Supplier Link Tickets shall be in electronic form except as

or "Throttling" means the reduction by Orbitz of Tickets to be processed by Orbitz through the Network Services on behalf of carriers as required to
meet the Worldspan Segment Obligation. In determining which Tickets to Throttle pursuant to this Agreement, Orbitz shall not consider the number of Segments in any Ticket; the parties acknowledge that
Orbitz is unable to Throttle a partial Ticket, and therefore, if Orbitz has one remaining Segment available for processing through the Network Services and a Ticket consists of more than one Segment,
the entire Ticket will be Throttled.

        1.42    "Ticket" means an airline passenger reservation (in the itinerary

2.    GENERAL  

        2.1    Engagement.    During the term hereof and in accordance with
the provisions of this Agreement, Orbitz shall provide to Airline, and Airline shall purchase from Orbitz the Network Services. 

        2.2    Subcontractors.    Upon prior written approval of Airline,
Orbitz may subcontract its performance of all or a portion of the Services to one or more Subcontractors, provided that Orbitz remains responsible for the work performed by such Subcontractor and for
Subcontractor's compliance with all of its obligations pursuant to this Agreement. Prior to performing any Services, each Subcontractor shall execute a written agreement with Orbitz containing
protections for Airline's confidential information and proprietary rights that are at least as protective as the terms and conditions of this Agreement. Notwithstanding the foregoing, however,
(i) Airline has the right, in good faith, to deny any Subcontractor access to its facilities, systems and Confidential Information; and (ii) Orbitz may not engage a Subcontractor who is
then-currently providing any services to a Competitor of Airline without first obtaining Airline's written approval. 

        2.3    Facilities.    Airline will provide Orbitz with
Airline-supervised access to those portions of Airline's premises and computer systems that Orbitz may reasonably require to perform the Services. Such access will be provided at mutually convenient
times during Airline's normal business hours, unless otherwise agreed by the parties. While working at Airline's premises, Orbitz employees and Subcontractors will adhere to Airline's rules and
regulations as they may exist from time to time; provided that such Subcontractors shall be informed of such rules and regulations. Orbitz agrees that it will immediately remove any employee or
Subcontractor working at Airline's premises (a) who violates any of Airline's workplace rules and regulations, (b) whose action or inaction constitutes a breach under this Agreement, or
(c) as requested by the Airline.

3.    MANAGEMENT  

        3.1    Relationship Managers.    Each party will designate a
Relationship Manager to act as the primary point of contact between the parties with respect to this Agreement. Each party from time to time may also appoint one or more Project Managers to manage
specific projects under this Agreement. The Project Managers will serve as the primary interface points between the parties with respect to such projects. 

        3.2    Reports.    [Reporting Format and
Specifics] 

        3.3    Project Problems.    In the event of any actual or potential
problem or delay in the Network Services or other development projects, the Relationship Managers will discuss the relevant source of such problem or delay, possible remedies and the potential impact
on the Network Services or other development projects within twelve hours after such problem or delay is identified or the beginning of the next business day (whichever is earlier). To assist in such
discussions, each Relationship Manager may invite any applicable Project Managers or other persons to such discussions. 

4.    Intentionally left blank  

5.    NETWORK SERVICES  

        5.1    Network Services.    Upon the Commencement Date and throughout
the term of this Agreement, subject to Airline performing its responsibilities set forth in this Agreement and the Specifications, Orbitz will provide the Network Services in accordance with the
Specifications. Subject to Sections 5.3 and 5.4, if a Ticket is eligible for the Network Services and complies with the Schedule and the Specifications, Orbitz shall issue the Ticket through the
Network Services. Orbitz will obtain from ATPCO (or such other third party agreed upon by the parties) the fare and fare rules, which apply to Airline's flights, Codeshare flights or flights sold
under the Airline's designator code in order to provide the Network Services in the event such information is not available to Orbitz through the Network Services. To the extent Orbitz is not able to
issue Tickets through the Network Services and such inability is not due to a failure by Orbitz to perform its obligations set forth in this Agreement and the Specifications (not including any
Throttling), then Orbitz shall issue Tickets through an available Reservation System in which Airline is a participant, and Airline will be charged and will pay the corresponding Reservation System
Fees payable by Airline with respect to any such Tickets, subject to Section 3.2 of the Airline Charter Associate Agreement (or similar provisions of any agreement that replaces the Airline
Charter Associate Agreement between Orbitz (or any of its Affiliates) and Airline in effect from time to time pursuant to which Airline provides Orbitz with published fare and inventory information
for air transportation for inclusion and sale on the Site), but Airline will not be responsible for any Network Fees payable hereunder related to such Tickets. In the event either party becomes aware
that Tickets cannot be issued by Orbitz through the Network Services for a continuous period of more than six (6) hours, such party will notify the other party's Project Manager or Relationship
Manager immediately upon becoming aware of such problem. Notwithstanding the foregoing, Orbitz shall remain obligated at all times during the term of this Agreement to correct and update the Orbitz
Software and the integration of the Orbitz Software with the Airline Host System to enable it to perform the Services in accordance with the Specifications. 

        5.2    Limitation on Uses of the Network Services.    The Airline Host
System may be accessed only by Orbitz Customers who access the Network Services to purchase Supplier Link Tickets through the Site. Any use of the Network Services or access to the Airline Host System
through the Network not contemplated by this Agreement, including but not limited to third party use or access to the Network, will be covered by a Change Request, a Statement of Work, or a separate
written agreement between the parties. Provided Airline has consented to such third party use or access to the Airline Host System through the Network for the issuance of Airline's Tickets as
contemplated in the previous sentence, Orbitz shall provide such third party access to Airline's Tickets through the Network on terms and 

6

 

conditions,
which shall be no less favorable to Airline than the terms and conditions set forth in this Agreement, subject to the negotiation of a mutually acceptable agreement between Orbitz and such
third party. 

        5.3    Throttling in 2004.    During the period from January 1,
2004 through December 31, 2004 and only to the extent that Orbitz is subject to the Worldspan Segment Obligation, then: 

        5.3.1    Beginning on the date Orbitz first issues a Ticket through the Network Services under a Supplier Link Agreement with DL
or UA (whichever is earlier), Orbitz shall limit Tickets booked and issued through the Network Services for the following Participating Carriers to the percentage of such Participating Carrier's total
Segments processed through the Site (in each case including Codeshare Segments) specified as follows (each, a "Cap" and collectively, the
"Caps"):
                                      . Orbitz will
manage the application of the Caps with the intent of reaching the specified Caps for
the time period between the date Orbitz first issues a Ticket through the Network Services under a Supplier Link Agreement with DL or UA (whichever is earlier) and December 31, 2004, on a
cumulative basis. 

        5.3.2    Subject to Section 5.3.3, beginning on the date Orbitz first issues a Ticket through the Network Services under
a Supplier Link Agreement with DL or UA (whichever is earlier) until such time as all of the Remaining Segment Carriers have each reached their respective Cap (the Cap for each Remaining Segment
Carrier shall be
                                      %, in each case
including the Remaining Segment Carrier's Codeshare Segments), Orbitz shall allocate all Remaining Segments as follows:
(i) while only one of DL or UA is processing Tickets through the Network Services, all Remaining Segments will be allocated among the Remaining Segment Carriers then issuing Tickets through
Network Services in accordance with each of their relative proportion of the total Tickets during the previous 3-month period and (ii) beginning on the date or dates that other
Remaining Segment Carriers commence issuing Tickets through the Network Services but before they have all reached their respective Caps, all Remaining Segments will be allocated among the Remaining
Segment Carriers then issuing Tickets through Network Services in accordance with their relative proportion of the total Tickets during the previous 3-month period. 

        5.3.3    Notwithstanding the requirements in Section 5.3.2, Orbitz shall have the right to limit the number of Remaining
Segments available to be allocated to the Remaining Segment Carriers as necessary (based on the Forecast) in order to meet the Worldspan Segment Obligation. In determining the number of Remaining
Segments, Orbitz shall use reasonable commercial efforts to ensure that the Worldspan Segment Obligation is satisfied using as few Segments from the Remaining Segment as possible, and Orbitz shall use
reasonable commercial efforts to allow Remaining Segments to exist, while at the same time satisfying the Worldspan Segment Obligation. 

        5.3.4    If all Participating Carriers have reached their respective Caps, then all additional Segments shall be divided among
all Participating Carriers in accordance with their respective Supplier Link Share. 

        5.3.5    Subject to Section 5.3.1, if any Participating Carrier is unable to reach its Cap (other than as a result of a
failure of the Network Services or Throttling) any Segments which would have been available to such Participating Carrier to attain such Participating Carrier's Cap will be treated as additional
Segments under Section 5.3.4. 

        5.3.6    During 2004, Orbitz may not Throttle Tickets with respect to
                                       below their
respective Caps (set forth in Section 5.3.1) unless Orbitz has first completely Throttled all other carriers. If all other carriers have been completely Throttled, then Orbitz shall Throttle
                                       as follows:
                                      . 

7

 

        5.4    Throttling in 2005 and Beyond.    

        5.4.1    Subject to Section 5.4.2, beginning on January 1, 2005 and continuing thereafter, no Caps shall apply to
Airline (or any Participating Carrier), and subject to Section 5.4.2, Airline (and each Participating Carrier) shall be allowed to process an unlimited number of Tickets through the Network
Services in accordance with the Specifications. 

        5.4.2    Subject to the restrictions set forth in Section 5.4.3 and 5.4.4, beginning on January 1, 2005 and
continuing thereafter, during such periods of time and to the extent that Orbitz is subject to the Worldspan Segment Obligation, Orbitz shall have the right to Throttle Tickets with respect to all
Participating Carriers as necessary (based on the Forecast) in order to meet the Worldspan Segment Obligation, on a pro rata basis in accordance with each Participating Carrier's Supplier Link Share. 

        5.4.3    From January 1, 2005 through December 31, 2006, Orbitz shall not Throttle Tickets with respect to
                                       below the
percentage of Segments set forth below ("Floor") unless Orbitz has first ceased processing
Tickets through the Network Services for all other carriers. The Floor applicable to
                                       is
                                      . If all other
carriers
have been completely Throttled, then Orbitz shall Throttle
                                       as follows:
                                      . 

        5.4.4    Orbitz may not Throttle Tickets with respect to Airline (or any Participating Carrier) in any month unless Orbitz has
completely ceased processing Tickets through the Network Services for any carrier that is not a Participating Carrier. 

        5.5    Throttling Payments.    For any Throttling that occurs on or
after January 1, 2005, Orbitz will reimburse Airline (and each Participating Carrier) in the amount of
$                                       for each
Segment Throttled, subject to the
limitations of Section 5.6 (the "Throttling Payment"). Orbitz will pay Airline the Throttling Payment on a quarterly basis within 30 days
following the end of the calendar quarter and shall include with such quarterly payment a report of the Throttling Payments made to each Participating Carrier since the date of the last report,
provided that if no Throttling Payments were made for any particular quarterly period, then no report shall be issued with respect to such quarterly period. 

        5.6    Limitations to Throttling Payments.    The sum of all
Throttling Payments provided by Orbitz to all Participating Carriers shall not exceed $3.0 million for 2005, $4.0 million for 2006, $5.0 million for 2007 and $5.0 million
per year for any year beyond 2007. 

        5.7    Excess Throttling; 4th Quarter Adjustments.    If
the number of Tickets subject to Throttling was overestimated by Orbitz in the Forecast and as a result Airline was Throttled by a number of Tickets in excess of the number actually necessary to meet
the Worldspan Segment Obligation for any calendar quarter, Orbitz will use commercially reasonable efforts to make available to Airline an additional allocation for Supplier Link Tickets in a future
calendar quarter during the same calendar year equal to such excess amount. Orbitz acknowledges that over-Throttling will cause Airline economic harm and will therefore endeavor to manage
Throttling so as to avoid over-Throttling and will delay Throttling to the extent possible until the second half of the year to reduce the risk that more Segments are Throttled than are
necessary based on the Worldspan Segment Obligation. 

        5.8    Throttling Due to a Safe Harbor Event.    Notwithstanding any
of the procedures for Throttling set forth in Sections 5.3 or 5.4, but subject to Orbitz's obligation to make Throttling Payments in Section 5.5 (as limited by Section 5.6), in
the event Orbitz provides Worldspan notice of a Safe Harbor Event and invokes its ability to avoid the payment of Minimum Segment Fees by availing itself of such Safe Harbor Event, then for so long as
Orbitz is required to discontinue processing any and all Tickets through the Network Services in order to avoid the payment of Minimum Segment Fees, then Orbitz shall cease processing Tickets through
the Network Services for all Participating Carriers, including 

8

 

Airline.
Notwithstanding the foregoing, Orbitz hereby acknowledges and agrees that Orbitz' cessation of processing Tickets through the Network Services in connection with its declaration of a Safe
Harbor Event pursuant to Orbitz' agreement with Worldspan will cause Airline economic harm and therefore, in the event of any such cessation, Orbitz agrees to reinstate processing Tickets through the
Network Services on the first date following such cessation that a Forecast, if then prepared by Orbitz in good faith and based upon reasonable assumptions, would reflect that, for the year in which
the cessation occurred, Orbitz would be able to comply with the Worldspan Segment Obligation if on such date Orbitz again commenced processing Tickets through the Network Services for all
Participating Carriers, including Airline. 

        5.9    Change to Worldspan Segment Obligation.    Orbitz shall not
agree to any increase in the Worldspan Segment Obligation so long as any Supplier Link Agreement remains in effect, and Orbitz shall notify Participating Carriers of any reduction to, or other
modification that affects in any way, directly or indirectly, the Worldspan Segment Obligation, which notice shall contain specificity as to the reduction or modification. Orbitz' right to Throttle
shall be updated to reflect any reduction in the Worldspan Segment Obligation, and this Agreement shall be amended to reflect the full benefit of the reduction. 

        5.10    Notice of New Network Service Features and
Functions.    Orbitz will, on an ongoing basis during the term, notify Airline in writing of any new capabilities, features or functions developed by Orbitz for the
Network Services or any different capabilities, features or functions made available to another carrier relating to the Network Services. In addition, Orbitz shall notify Airline in writing within ten
(10) days of offering any new or different capabilities, features or functions relating to the Network Services to any other carrier (including, but not limited to, all of the specifications
agreed upon between any carrier and Orbitz applicable to the Network Services) and Airline will have the option to participate in such new or different capabilities, features or functions on the same
terms and conditions which are no less favorable than those offered to any other carrier. Notwithstanding the foregoing, Orbitz will not be required to notify Airline of (i) any error,
correction or minor change that Orbitz may implement with respect to Network Services if such correction or change affects all carriers at substantially the same time and in substantially the same
manner or (ii) any changes or additions to the specifications applicable to the Network Services that are solely to accommodate the technology of a particular carrier and do not result in more
favorable treatment of such carrier. 

        5.11    Further Development.    Following the Commencement Date,
Orbitz shall provide additional development services with respect to the Orbitz Software and the Interface as follows: 

        5.11.1.    Changes or Modifications at the Request of Airline.    Upon Airline's request and
subject to mutually agreeable terms and conditions, Orbitz may provide to Airline development services (collectively, "Airline Development") that are in
addition to any development required to be performed by Orbitz in order to perform the Services in accordance with the Specifications or as provided in Section 5.11.2 hereof. Any Airline
Development shall be performed pursuant to a Change Request or a Statement of Work entered into by the parties in accordance with Section 8 hereof. The parties agree that in the event Orbitz
provides Airline with any Airline Development, Orbitz will charge Airline rates that are no higher than those it charges to other carriers for similar types of development services or for similar
enhancements or modifications. Orbitz' current hourly rates for Airline Development are set forth in Schedule D hereto. 

        5.11.2    Changes or Modifications Required by Law or by Industry Standards.    Upon either
party's request that the Network Services be modified to meet or be compatible with any (a) applicable law or regulation, including but not limited to any laws or regulations administered or
promulgated by the U.S. Department of Transportation, or (b) governmental or industry standards, that have been adopted on an industry-wide basis, Orbitz and Airline will mutually
agree in writing on the parties' respective development obligations regarding such modifications 

9

 

and
any amounts to be paid by the parties for the development of such modifications or other services that are performed, pursuant to the procedures in Section 8 of this Agreement. In the event
that the parties are unable to reach agreement on such changes in good faith after reasonable deliberation, and continued use of the Network Services would violate applicable law or regulation, or
government or industry standards, either party may terminate this Agreement by giving the other party at least 30 days notice of its intent to terminate. 

        5.12    Compliance.    During the term of this Agreement, Orbitz will
ensure that the Network Services comply with all applicable interline reservations policies, procedures and message formats and are in accordance with the requirements set forth in the Specifications.
Orbitz agrees that all Supplier Link Tickets and Inventory will be marketed, displayed, filed, sold and settled (a) through ARC in accordance with its agreement with ARC, Airline's addendum
thereto and any ARC policies and procedures and (b) in accordance with any and all applicable laws, industry standard and governmental regulations, including the Department of Transportation's
Notice dated January 18, 2001 regarding the "Prohibition on Deceptive Practices in the Marketing of Airfares to the Public using the Internet". Orbitz will, at all times during the term of this
Agreement, remain in good standing with ARC. Orbitz shall process all Supplier Link Tickets created by Orbitz Customers, and shall handle information relating to Airline, with the same care and
timeliness as the Tickets and information of all other airlines and without regard to the identity of the carrier but no less than what is reasonable. Orbitz will review and work on rejected messages
and, where justified by volume, investigate methods of reducing and resolving such rejected messages. Without the prior written consent of Airline, Orbitz will not (i) make changes to the
functionality of its system or services in a manner that increases the fees payable by Airline to Orbitz under this Agreement (including, without limitation, changes to functionality that result in
the generation of multiple separate tickets for travel to a specific location), or (ii) make changes to its processes or procedures related to the Network Services in a manner that materially
increases the fees payable by Airline to the Airline Host System provider. Orbitz will not provide any type of incentive to Customers that would motivate Customers to request the issuance of multiple
separate Tickets for travel to a specific location. 

        5.13    Display.    Orbitz agrees to display Inventory in an unbiased
manner in accordance with Section 3.1 of the Airline Charter Associate Agreement. 

        5.14    Reporting; Audit.    Orbitz shall provide to Airline in
electronic form all back-up documentation and information specified in the Specifications or otherwise reasonably requested by Airline to substantiate the charges to Airline pursuant to
this Agreement, provided that Orbitz may provide such documentation and information in a manner that protects the confidentiality of any information that Orbitz by law or contract is prohibited from
disclosing to Airline. Airline will also have the right, at anytime during the term of this Agreement, upon not less than five (5) days prior written notice to conduct, or to cause an
independent auditor retained by Airline to conduct, an audit of Orbitz' books and records with respect to the Services provided to Airline hereunder to verify the amounts charged Airline hereunder and
Orbitz' compliance with its obligations hereunder. If any such audit reveals that the amounts paid to Orbitz by Airline pursuant to this Agreement have been greater than or less than the amounts
actually due to Orbitz pursuant to this Agreement, then Orbitz shall promptly pay to Airline, or charge Airline, for the amount by which such paid amounts are greater than, or less than, such amounts
actually due. Airline agrees that it will notify Orbitz if Airline has knowledge that any Orbitz Customer is using the Network Services in an improper fashion. Upon receipt of such notice and
confirmation of the matters described therein, or if Orbitz discovers such improper use independent of information supplied by Airline, Orbitz shall report in writing to Airline, the extent of the
misuse discovered and shall take such action as is reasonably necessary to correct the improper use of the Network Services. Airline may terminate this Agreement pursuant to Section 17.2 upon
notice to Orbitz if Orbitz fails to take prompt action to correct the improper use of the Network Services with respect to an Orbitz Customer following a request by Airline to take such action. 

10

 

        5.15    Support and Security.    For Network Services failures or
other reported problems, each party will provide, or have its authorized agent provide, the technical support services described in the Specifications. Airline agrees to assist Orbitz in interpreting
ATPCO rules to the extent it does for other ARC-accredited agencies. Airline agrees to use commercially reasonable efforts to maintain, or cause to be maintained, the Airline Host System.
Orbitz is solely responsible for hosting, and agrees to maintain, the Network at Orbitz's expense (except for any fees payable hereunder). Orbitz will use its commercially reasonable efforts to
promptly fix or provide a work around solution for material, identifiable errors in the Network Services at no additional charge. Orbitz will provide a secure environment for the Network and Inventory
provided to Orbitz by Airline in accordance with the security standards set forth in the Specifications. Orbitz agrees to notify Airline as soon as possible, but in any event within six
(6) hours or by 9 a.m. of the next business day, whichever is shorter, if it learns of a suspected or actual security breach. 

        5.16    Customer Support.    [Customer Support
Specifics] 

        5.17    Out-of Scope Services.    Orbitz and Airline
acknowledge and agree that certain transactions identified in Section 4 of Schedule C to this Agreement will be considered as "normal exclusions" from the Network Services. The parties
agree that the Orbitz Software is not currently designed to support or process these transactions through the Network Services and Orbitz will not be required to enable the Network Services to process
or support such transactions unless otherwise agreed by the parties in writing. 

        5.18    Direct Billing.    Airline may during the term of this
Agreement request that certain Orbitz Customers or other third parties to be qualified for direct billing by Orbitz. Upon mutual agreement by Orbitz and Airline, and provided such Orbitz Customer or
other third party executes an appropriate agreement with Orbitz, (i) Orbitz will invoice such Orbitz Customer or other third party for the Network Fees for Tickets booked by such Orbitz
Customer or other third party and (ii) Airline will have no obligation to pay the applicable Network Fees for Tickets booked by such Orbitz Customer or other third party. 

6.    AIRLINE OBLIGATIONS.  

        6.1    Airline Charter Associate.    During the term of this
Agreement, each party agrees that it will not be in material default of its Airline Charter Associate Agreement or any other commercial agreement pursuant to which Airline provides Orbitz with
published fare and inventory information for air transportation for inclusion and sale on the Site (provided that such party shall have the opportunity to cure any such default within the cure period
stated in such agreement). In the event that the Airline Charter Associate Agreement (or another commercial agreement pursuant to which Airline provides Orbitz with published fare and inventory
information for air transportation for inclusion and sale on
the Site) is terminated as a result of an uncured material default by either Airline or Orbitz, the non-defaulting party may, following notice and expiration of the period to cure such
default provided in Section 17.2), terminate this Agreement for breach pursuant to Section 17.2, and upon any such termination, neither party shall have any further obligation under this
Agreement. 

        6.2    Assistance and Cooperation.    Upon request by Orbitz, Airline
will provide Orbitz with reasonable assistance and cooperation in the performance of the Services in accordance with the express provisions contained in this Agreement and the Specifications. Airline
agrees to provide Orbitz with reasonable advance notice of any changes to the Airline Host System that Airline reasonably believes will affect the Network Services. 

        6.3    Inventory.    Airline shall provide Orbitz with access to
Inventory information in accordance with the formatting and delivery requirements set forth in the Specifications. 

11

 

        6.4    Fulfillment.    [Fulfillment Specifics] 

        6.5    Availability Data.    Airline will provide to Orbitz, or such
other party as Orbitz may, with Airline's consent, which consent shall be limited to use in connection with this Agreement, designate to act on behalf of Orbitz, complete, accurate and timely direct
access to Airline's availability data such that the quality of data is at least as good as that available via Worldspan or any other Reservation System providing services to Orbitz. In the event the
parties mutually agree that Orbitz will use Worldspan availability data to provide the Network Services (but not process substantially all bookings though Worldspan), Airline will pay Orbitz the
amount owed by Orbitz to Worldspan as set forth in the Orbitz/Worldspan Agreement to access through Worldspan availability data with respect to flights sold under Airline's designator code. 

7.    FEES AND PAYMENT  

        7.1    Fees.    Following the Commencement Date, Airline will pay to
Orbitz for each Supplier Link Ticket issued the Network Fees set forth in the Network Fees Schedule attached hereto as Schedule B; provided that, no Network Fees shall be due or payable for any
Ticket booked or issued through Worldspan. 

        7.2    Reimbursable Expenses.    If agreed to in advance in writing by
Airline, Airline will reimburse Orbitz for reasonable, actual, out-of-pocket expenses incurred by Orbitz in conjunction with out of town travel required for Orbitz to perform
the Services. In the event Airline approves any such travel by Orbitz, Airline will, at its option, provide Orbitz with Coach Class space available or other tickets for air travel on Airline or
reimburse Orbitz the actual cost for Coach Class, round trip air travel. Orbitz shall utilize Airline's air transportation unless specifically approved otherwise, on a
case-by-case basis, by Airline's Relationship Manager. Other reimbursable expenses will be limited to reasonable and actual expenses for lodging, meals, local transportation
and incidentals only as are required by Orbitz in the performance of its obligations hereunder. Unless specifically agreed upon otherwise by Airline's Relationship Manager, rental car expenses will
only be reimbursed if the car is necessary for Orbitz to complete its obligations hereunder. Receipts will be required for any expenditure totaling US $10.00 or more. Air travel, hotel and rental car
expenses will only be reimbursed if reservations are made through Airline, unless Airline declines to make such reservations. Notwithstanding the foregoing, the parties may agree upon, in advance of
any travel, a per diem payment in lieu of reimbursement. 

        7.3    Payment Terms.    Orbitz will invoice Airline monthly for any
fees or expenses payable by Airline hereunder. Airline will pay to Orbitz within 30 days of receipt of an Orbitz' invoice all undisputed amounts set forth on such invoice. In the event that
Airline asserts in good faith that any item or items on an invoice are not correct, then Airline will within thirty (30) days of receipt of such invoice (a) deliver written notice to
Orbitz explaining in detail why Airline believes that an item or items are not correct and (b) pay to Orbitz all amounts on the invoice that are not the subject of a good faith dispute by
Airline. 

        7.4    Most Favored Buyer.    If prior to the execution of, or during
the term of this Agreement, Orbitz provides to another airline services (including but not limited to the Network Services) that are the same or substantially the same as those provided to Airline
under this Agreement: (i) under a more favorable fee schedule than the fee schedule in effect for Airline but with substantially the same terms and conditions, then Orbitz will immediately
notify Airline of the existence of such agreement and the more favorable fee schedule will apply immediately to Airline effective as of the effective date of such agreement with the other airline;
and/or (ii) on terms and conditions that taken as a whole are more favorable to such other airline than the terms hereof are favorable to Airline, then such more favorable terms and conditions
will apply to Airline and this Agreement; provided that in determining whether the fee schedule and/or the terms and conditions of such other agreement are more favorable to the other airline than
those set forth herein, any set-up fees associated with the initial development of the 

12

 

Interface
shall be disregarded; provided, however, that Orbitz agrees that set-up fees associated with any Supplier Link Agreement shall reflect only the actual costs attributable to
implementation of Network Services. 

        7.5    Taxes.    The Network Fees are exclusive of all sales, use,
customs, excise, value added, ad valorem or other similar tax, assessment or duty ("Taxes") that Orbitz may be legally obligated to charge Airline
on account of the payment of any amounts from Airline to Orbitz for the provision of goods or for performing the Services pursuant to this Agreement. Orbitz shall pay and be solely responsible for all
taxes that are: (i) on, based on, or measured by, gross or net income or gross or net receipts (including any capital gains taxes or minimum taxes) of Orbitz, or taxes which are capital, doing
business, excess profits, net worth, or franchise taxes of Orbitz; (ii) caused by or arising out of the willful misconduct or negligence of Orbitz; or (iii) any interest, additions to
tax, or penalties associated with the taxes set forth in (i) or (ii) above. Orbitz shall be registered to collect sales tax and shall be responsible for the collection of applicable sale
and use taxes in jurisdiction where such registration is required by law. Airline shall pay or reimburse Orbitz for the payment of all Taxes that are lawfully imposed by any governmental authority and
are based on or measured by any payments of Airline pursuant to this Agreement. All such Taxes shall be separately stated on the invoice. Airline shall not pay any Taxes if: (i) a specific
exemption applies to (a) the products or services purchased hereunder, or (b) any transaction occurring pursuant to this Agreement, (ii) Airline has provided Orbitz with written
confirmation that Airline is authorized to make tax payments directly to the applicable taxing authorities, or (iii) Orbitz is obligated to pay the taxes as set forth herein. Orbitz shall
promptly, upon receipt from any tax authority of any levy, notice, assessment, or withholding of any tax for which Airline may be obligated, notify Airline in writing. If under the applicable law of
the taxing jurisdiction Airline is allowed directly to contest such tax in its own name, then Airline shall be entitled, at its own expense and in its own name, to contest the imposition, validity,
applicability or amount of such tax and, to the extent permitted by law, withhold payment during pendency of such contest. If Airline is not permitted by law to contest such tax in its own name, upon
Airline's request, Orbitz shall in good faith and using best efforts, at Airline's direction and expense, contest the imposition, validity, applicability or amount of such tax. Orbitz shall in good
faith and using best efforts: (i) supply Airline with such information and documents reasonably requested by Airline as are necessary or advisable for Airline to (a) recover or seek a
refund of any sales or use tax paid by Airline as a result of this Agreement; or (b) control or participate in any proceeding to the extent permitted herein, and (ii) reasonably assist
Airline with evidentiary and procedural development of any such proceeding or contest. If all or any part of any Taxes are refunded or credited, Orbitz shall repay Airline such part thereof as Airline
paid, including any interest received thereon. Upon Airline's request, Orbitz shall delineate the fees among the component portions of the products and services contracted for in this Agreement. The
term "Component Portions" for purposes of this paragraph shall include, but is not limited to: (i) maintenance, including upgrades and enhancements, (ii) installation,
(iii) support, and (iv) training and related manuals. 

8.    CHANGE REQUESTS  

        8.1    Change Request.    If either party wants to request a
modification, addition or change in the Services, including without limitation a modification to the Network Services, other than those changes or modifications that Orbitz is required to perform
pursuant to this Agreement, its Relationship Manager will submit a completed Change Request to the Relationship Manager of the other party. The Change Request will adequately describe (a) the
requested modification, (b) the estimated resources required to implement the modification, (c) its impact on a Statement of Work if it is a modification or development as contemplated
by Section 5.4, (d) its impact on the Network Fees, and (e) any required information and resources by Airline. Notwithstanding the foregoing, Orbitz may modify, add to or change
the Network Services upon not less than thirty (30) days prior notice to Airline, without Airline's approval, if (i) the proposed modification, addition or change is being made in the
same 

13

 

manner
to the Network Services Orbitz provides to all other carriers, (ii) such modification, addition or change does not increase the Network Services Fees, (iii) such modification,
addition, or change does not adversely affect the functionality or reliability of the Services or the processes and procedures of Airline, and (iv) such modification, addition, or change does
not result in additional development work for Airline. 

        8.2    Change Acceptance.    Upon receipt of a completed Change
Request, the recipient Relationship Manager will either (a) expressly accept the proposed modification without qualification within thirty (30) days after its receipt or (b) defer
the request for discussion of the next scheduled or emergency status meeting. The Relationship Managers will use good faith efforts to resolve any deferred proposed modification expeditiously. Neither
party shall have any obligation to enter into a Change Request proposed by the other party, and no proposed modification will be effective unless accepted in writing by the authorized employees of
both parties. Any Change Request that is accepted and so executed will thereafter constitute a formal amendment of this Agreement. 

9.    CONFIDENTIALITY.  

        9.1    Protection of Confidential Information.    Each party agrees to
maintain strict confidentiality regarding the subject matter of this Agreement. Each party will take such measures that are necessary to protect against the disclosure or use of the Confidential
Information of the other party as it takes to protect its own proprietary or confidential information (but in any case no less than reasonable measures). Each party agrees that the other party will
have no adequate remedy at law if there is a breach or threatened breach of this Section 9 and, accordingly, that either party will be entitled (in addition to any legal or equitable remedies
available to such party) to injunctive or other equitable relief to prevent or remedy such breach. 

        9.2    Restrictions on Disclosure and Use.    Unless expressly
authorized in writing by the Disclosing Party or as authorized by the Airline Charter Associate Agreement, the Receiving Party agrees to retain the Confidential Information in confidence and shall not
copy or disclose the Confidential Information to, or use the Confidential Information for, the benefit of any third party, except as set forth in this Section 9.2. Confidential Information may
be disclosed on a need to know basis to the Receiving Party's employees, Affiliates, and independent contractors who are parties to a written agreement with the Receiving Party which prohibits the
disclosure of Confidential Information, and limits its use to the benefit of the Receiving Party and its Affiliates, using reasonable technical and organizational measures to protect the
confidentiality of the information. 

        9.3    Exclusions.    Notwithstanding any other provisions of this
Agreement, each party acknowledges that Confidential Information shall not include any information which (a) is or becomes publicly known through no wrongful act of the Receiving Party;
(b) is at the time of disclosure, already known to the Receiving Party without restriction on use or disclosure and was not obtained from the Disclosing Party or its contractors under a duty of
confidentiality; or (c) is independently developed or obtained from a third party by the Receiving Party without breach of this Agreement. In addition, nothing contained in this
Section 9 or elsewhere in this Agreement shall restrict Orbitz from complying with ARC reporting requirements, or the reporting requirements of any such other settlement company to which Orbitz
is required to report. 

        9.4    Relief from Obligations.    Either party will be relieved of
its confidentiality obligations hereunder if and to the extent that Confidential Information (a) is disclosed pursuant to the lawful requirement of a governmental agency, or disclosure is
required by operation of law, provided that the party making the disclosure requires reasonable measures to protect the security of the information, has given timely notice to the Disclosing Party and
the Disclosing Party has been permitted at its expense to interpose objections, defenses or obtain a protective order limiting disclosure and use of the information; or (b) is explicitly
approved for release by written authorization of the Disclosing Party. 

14

 

        9.5    Ownership of Confidential Information.    No license, express
or implied, in the Confidential Information is granted by one party to the other party other than to use such Confidential Information in the manner and to the extent authorized by this Agreement.
Each party shall retain the title and full ownership rights to their respective Confidential Information. Each party agrees that upon the request of the Disclosing Party, it shall return to the
Disclosing Party all of the Disclosing Party's Confidential Information in such party's possession or control. 

        9.6    No Publicity.    Neither party will issue a press release,
advertisement or public statement concerning the existence of this Agreement, its contents or the transactions contemplated by it without the express written consent of the other for each such event. 

        9.7    Data Privacy.    With respect to any information provided by
the other party that is processed under this Agreement that relates to, or is about, an identified or identifiable person, each party shall at all times (i) use reasonable efforts to protect
such information and (ii) comply with all applicable laws and regulations, including but not limited to data privacy laws, in its use of such information. 

10.    LICENSE GRANT.  

        10.1    By Airline.    Airline grants Orbitz a limited, worldwide,
non-exclusive, royalty-free right and license, without the right to sublicense, to: (a) access, display, transmit and distribute Inventory made available by Airline
through the Network to Orbitz Customers in response to Queries on the Site and (b) use any information owned and provided by Airline hereunder about the Airline Host System, the Airline
Specifications and the Inventory solely for the purposes of meeting Orbitz's obligations hereunder. The foregoing is a license merely to access the Airline Host System and exchange information with
it. No rights are granted by or implied in this Agreement for Orbitz or Orbitz Customers to modify in any manner or use directly the Airline Host System, except as provided herein. 

        10.2    By Orbitz.    Orbitz grants Airline a limited, worldwide,
non-exclusive, royalty free right and license to: (a) use the Network to access all Orbitz Customer records that contain at least one Airline or Codeshare flight segment to allow
Airline to test and validate the operation, compliance and quality of the Network Services prior to implementation of the Network Services and during mutually agreed upon testing periods and
(b) use the Network and any information provided by Orbitz hereunder about the Orbitz Software solely for any purposes of obtaining the Services contemplated by this Agreement and meeting
Airline's obligations to Orbitz under this Agreement. 

11.    PROPRIETARY RIGHTS.  

        11.1    Orbitz.    Subject to Sections 11.2 and 11.3, as between
Airline and Orbitz and to the extent of Orbitz' prior ownership rights, Airline acknowledges and agrees that Orbitz will own all patents (including any business process patents), rights to file for
patents, inventions, copyrights, trademarks, trade secrets and all other right, title and interest (including any renewals or extensions) in or to the Network, the Orbitz Software and any interfaces,
networks, configurations, programs (including without limitation, those programs that integrate the Network Services with the Airline Host System) and other systems developed by Orbitz or its
employees or Subcontractors during the performance of this Agreement, and including, without limitation, any derivative works thereof created by Orbitz or its employees or Subcontractors. Airline
hereby assigns and agrees to assign to Orbitz all rights that Airline may have or
acquire in or to such works for no additional consideration. No other person will acquire or retain any rights in or to such works, unless Orbitz otherwise agrees on a
case-by-case basis. At Orbitz' request, Airline will cause the execution of the instruments that may be appropriate to give full legal effect to this Section for no additional
consideration. 

        11.2    Developments.    With respect to any development performed by
Orbitz at the request of Airline subsequent to the Commencement Date, the parties will determine, in connection with such request, the ownership of proprietary rights thereto. 

15

 

        11.3    Prior Agreements.    Nothing in this Agreement will affect the
proprietary rights of Airline in any intellectual property that Orbitz has agreed in a prior agreement will be owned by Airline. 

        11.4    Airline Information.    As between Airline and Orbitz and to
the extent of Airline's prior ownership rights, Orbitz acknowledges and agrees that Airline will own all patents (including any business process patents), rights to file for patents, inventions,
copyrights, trademarks, trade secrets and all other right, title and interest (including any renewals or extensions) in or to (a) the Inventory, the Airline Specifications and the Airline Host
System, and all modifications thereto and derivatives of the foregoing, and (b) and the Airline Software and any interfaces, networks, configurations, programs and other systems developed by or
on behalf of Airline or its employees or subcontractors during the performance of this Agreement, and including without limitation any derivative works thereof created by or on behalf of Airline or
its employees or subcontractors. Except as otherwise explicitly provided in this Agreement, Orbitz shall have no right or license to use, reproduce, transfer, disclose, display or distribute
(electronically or otherwise) any technology or intellectual property rights in the Airline Specifications, Inventory, Airline Host System or Airline Software, and all other developments created by,
on behalf of Airline. Orbitz hereby assigns and agrees to assign and will cause its Subcontractor to assign, to Airline all rights that Orbitz may have or acquires in or to such works or rights for no
additional consideration. At Airline's request, Orbitz will cause the execution of such instruments that may be appropriate to give full legal effect to this Section 11.4 for no additional
consideration. 

        11.5    Interface.    Except as otherwise agreed to by the parties in
this Agreement, the Specifications and any Change Request or any Statement of Work or otherwise, as between Airline and Orbitz, each party shall own all right, title and interest in such portions of
the Interface and the functionalities designed to integrate the Network with the Airline Host System as such party creates and/or develops pursuant to this Agreement or any prior agreement between the
parties. Notwithstanding this Section 11.3, in no event will Airline be deemed to have any right, title or interest in the Network, and in no event will Orbitz be deemed to have any right,
title or interest in the Airline Host System, the Airline Software or the Airline Specifications as a result of this Agreement. 

12.    NON-EXCLUSIVITY.    The relationship between Airline and Orbitz as set forth in this
Agreement will be non-exclusive. Nothing in this Agreement is intended to prevent either party from entering into similar agreements with any other party. Airline may participate in other
Internet travel sites similar to the Network and may obtain services from other entities similar to the Network Services. Orbitz may permit other carriers to participate in the Network and may provide
services similar to the Services to other carriers. Orbitz and Airline may market, maintain, service and support Internet travel sites that compete with or provide functionality similar to the
Network. This Agreement will not confer any rights on one party to restrict the other party's ability to offer fare information or to do business, or choose not to do business, with any other airline,
Internet travel provider site, or any other entities. 

13.    WARRANTIES AND DISCLAIMERS  

        13.1    General Warranty.    Each party represents and warrants that
(a) it has the full corporate authority to execute this Agreement and perform its obligations hereunder, (b) the execution or performance of this Agreement will not violate or be
considered a breach of any obligation of such party to any third party and (c) the execution or performance of this Agreement will not violate any applicable law or regulation. 

        13.2    Specific Warranty.    Orbitz represents and warrants that
(a) it has sufficient rights or license in or to the Network and the Orbitz Software to perform the Services, (b) it will perform the Services in a good and workmanlike manner and in
accordance with the Specifications and (c) the number of segments Orbitz must book via the Worldspan Reservation System to achieve the highest inducement level is
                                       air segments
and Orbitz is obligated to pay Minimum Segment Fees if Orbitz fails to book 16,000,000 total air and car segments via the Worldspan
Reservation System. 

16

 

Except
as provided in Section 5.2.2 hereof, during the term of this Agreement, Orbitz shall maintain the availability of the Network Services for the issuance of Supplier Link Tickets in
accordance with the Specifications. In case of breach of the warranty set forth in subsection (b) above, Orbitz will correct or re-perform the defective Services, or refund the fees
actually paid to Orbitz for the defective Services. Airline acknowledges and agrees that this Section 13.2 and Section 5.1 set forth its exclusive remedy and Orbitz' exclusive liability
for any claim of breach of warranty with respect to the Services. The limitations in the foregoing sentence shall not apply to any failure by Orbitz to perform hereunder that results from the gross
negligence or willful misconduct of Orbitz, its officers, employees, representatives, agents, contractors or subcontractors, the breach by Orbitz of its confidentiality obligations pursuant to
Section 9 and the indemnities set forth in Section 14 hereof. 

        13.3    Limitation.    The warranties and remedies specified in this
Section will not apply if the Services are defective due to extrinsic causes outside the reasonable control of the warranting party, such as (a) natural disasters, including without limitation
fire, smoke, water, earthquakes or lightning, (b) electrical power fluctuations or failures, (c) neglect or misuse by either party, (d) incorrect information provided by Airline
regarding Inventory (e) a correction or modification of a Service not provided or recommended by Orbitz, or (f) the combination of the Services with other items or services (other than
the Airline Host System to the extent it is operated in accordance with the Specifications) with which the Services are not intended to be used. In addition, Airline shall not be responsible or liable
for unavailability or errors or omissions of the Interface, the Airline Host System or Inventory due to (i) errors or omissions in Orbitz's interpretation or transmission of Inventory, except
to the extent that such errors originated with Airline, (ii) errors in HTML or other coding provided by Orbitz or its employees or Subcontractors, (iii) third party information of any
kind whatsoever, or (iv) any matters listed in Section 19.5. 

        13.4    WARRANTY DISCLAIMER.    EXCEPT AS EXPRESSLY PROVIDED IN THIS
AGREEMENT, ALL WARRANTIES, CONDITIONS, REPRESENTATIONS AND GUARANTEES WITH RESPECT TO THE SERVICES, INCLUDING WITHOUT LIMITATION THE ORBITZ SOFTWARE, WHETHER EXPRESS OR IMPLIED, ARISING BY LAW,
CUSTOM, PRIOR ORAL OR WRITTEN STATEMENTS BY ORBITZ, ITS AGENTS OR OTHERWISE (INCLUDING, BUT NOT LIMITED TO, ANY WARRANTY OR CONDITION OF SATISFACTORY QUALITY, ACCURACY, UNINTERRUPTED USE, TIMELINESS,
SEQUENCE, TRUTHFULNESS, COMPLETENESS, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR NON-INFRINGEMENT AND ANY IMPLIED WARRANTIES ARISING FROM TRADE USAGE, COURSE OF DEALING OR COURSE
OF PERFORMANCE) ARE HEREBY OVERRIDDEN, EXCLUDED AND DISCLAIMED. 

14.    INDEMNITY.  

        14.1    Indemnification.    Orbitz will indemnify, defend, and hold
harmless Airline, its directors, officers, employees, and agents (each, an "Indemnified Party") from and against all any and all costs, demands, losses,
claims (including any claim by a third party), liabilities, fines, penalties, assessments, damages, including, without limitation, interest, penalties, reasonable attorneys' fees and expenses and all
amounts paid in proceedings, claims, complaints, disputes, arbitrations, investigations, defense or settlement of any of the foregoing, connected with the furnishing of any services or data by Orbitz
pursuant to this Agreement (including but not limited to actual or alleged infringement or misappropriation of any trade name, patent, copyright, trade secret or other property right based on any
software, program, service and/or other materials furnished by Orbitz hereunder, including the Site); provided, the foregoing shall not apply to the extent of claims or liabilities resulting from the
negligence or willful misconduct of Airline, its directors, officers, employees or agents. 

        14.2    Indemnification Procedures.    If any action, claim or other
proceeding shall be brought against any Indemnified Party, and it shall notify Orbitz of the commencement thereof, Orbitz shall be entitled 

17

 

to
assume the defense thereof at its own expense, with counsel satisfactory to such Indemnified Party in its reasonable judgment; provided, however, that any Indemnified Party may, at its own expense,
retain separate counsel to participate in such defense at its own expense. Notwithstanding the foregoing, in any action, claim or proceeding in which both Orbitz, on the one hand, and an Indemnified
Party, on the other hand, are, or are reasonably likely to become, a party, such Indemnified Party shall have the right to employ separate counsel at the reasonable expense of Orbitz and to control
its own defense of such action, claim or proceeding if, in the reasonable opinion of counsel to such Indemnified Party, a conflict or potential conflict exists between Orbitz, on the one hand, and
such Indemnified Party, on the other hand, that would make such separate representation advisable; provided, however, that Orbitz shall not be liable for the fees and expenses of more than one counsel
to all Indemnified Parties. Orbitz agrees that it will not, without the prior written consent of the Indemnified Party, settle, compromise or consent to the entry of any judgment in any pending or
threatened claim, action or proceeding relating to the matters contemplated hereby (if any Indemnified Party is a party thereto or has been actually threatened to be made a party thereto) unless such
settlement, compromise or consent includes an unconditional release of the Indemnified Party from all liability arising or that may arise out of such claim, action or proceeding. Orbitz shall not be
liable for any settlement of any claim, action or proceeding effected against an Indemnified Party without Orbitz's written consent, which consent shall not be unreasonably withheld. 

        15.    DAMAGES LIMITATIONS.    EXCEPT FOR THE INDEMNIFICATION
OBLIGATIONS OF THE PARTIES EXPRESSLY SET FORTH HEREIN AND CLAIMS ARISING OUT OF ANY BREACH OF SECTION 9, WITH RESPECT TO EACH OF WHICH LIABILITY SHALL NOT BE LIMITED PURSUANT TO THIS
SECTION 15, UNDER NO CIRCUMSTANCES WILL EITHER PARTY BE LIABLE FOR ANY CONSEQUENTIAL, INDIRECT, SPECIAL, PUNITIVE OR INCIDENTAL DAMAGES OR LOST PROFITS, WHETHER FORESEEABLE OR UNFORESEEABLE,
BASED ON THE OTHER PARTY'S CLAIMS (INCLUDING, BUT NOT LIMITED TO, CLAIMS FOR LOSS OF DATA, GOODWILL, USE OF MONEY, USE OF THE NETWORK OR USE OF THE SERVICES, INTERRUPTION IN USE OR AVAILABILITY OF
INFORMATION, STOPPAGE OF WORK OR IMPAIRMENT OF OTHER ASSETS), ARISING OUT OF BREACH OR FAILURE OF EXPRESS OR IMPLIED WARRANTY, BREACH OF CONTRACT, MISREPRESENTATION, NEGLIGENCE, STRICT LIABILITY IN
TORT OR OTHERWISE. EXCEPT FOR THE INDEMNIFICATION OBLIGATIONS OF THE PARTIES EXPRESSLY SET FORTH HEREIN, CLAIMS ARISING OUT OF ANY BREACH OF SECTION 9 AND AIRLINE'S PAYMENT OBLIGATIONS, WITH
RESPECT TO EACH OF WHICH LIABILITY SHALL NOT BE LIMITED PURSUANT TO THIS SECTION 15, IN NO EVENT WILL THE AGGREGATE LIABILITY WHICH EITHER PARTY MAY INCUR TO THE OTHER PARTY IN ANY ACTION OR
PROCEEDING RELATING TO THIS AGREEMENT EXCEED THE GREATER OF (A) THE TOTAL FEES PAYABLE BY AIRLINE TO ORBITZ DURING THE TWELVE (12) MONTH PERIOD PRECEDING THE EVENT THAT RESULTED IN SUCH
LIABILITY, OR (B)
 $                                      . THIS
SECTION 15 WILL APPLY IN ALL CASES EXCEPT AND TO THE EXTENT THAT APPLICABLE LAW SPECIFICALLY REQUIRES LIABILITY,
DESPITE THE FOREGOING EXCLUSION AND LIMITATION. 

16.    INSURANCE  

        16.1    Minimums.    [Insurance Specifics] 

        16.2    Endorsement.    Orbitz agrees to insure (or
self-insure) all losses to its owned or leased tools and equipment used in the delivery of the Products and provision of the Services and agrees to obtain an endorsement from its insurance
carrier waiving its right of subrogation against Airline. 

        16.3    Rating.    If requested by Airline, Certificates of Insurance
shall be delivered to Airline evidencing compliance with the insurance terms of this Agreement. All of the above insurance shall be 

18

 

written
through a company or companies with an A.M. Best rating of A-(VIII) or better. Orbitz will notify Airline in writing in advance of the effective date of any material
change in or cancellation of such insurance; provided Orbitz receives such advance notice from the insurer. Orbitz' failure to provide or to maintain the insurance required during the term of this
Agreement shall be deemed a material breach of this Agreement. 

17.    TERMINATION.  

        17.1    Term.    This Agreement shall commence on the Effective Date
and shall continue until
                                      ; provided that,
 Airline may terminate this Agreement upon prior written notice to Orbitz, at any time after the completion of the
2ndanniversary of the Effective Date; and further provided that, Airline shall have the option to extend the term of this Agreement beyond the
                                       (on the same
terms and conditions as in existence at such time) to a date coterminous with the Airline Charter Associate Agreement (or replacement
commercial agreement), if Airline and Orbitz have extended the Airline Charter Associate Agreement (or replacement commercial agreement) between them to a date beyond. 

        17.2    Termination for Cause.    In addition to all other termination
rights set forth herein, either party may terminate this Agreement for cause in the event that the other party fails to cure a breach of this Agreement within
                                       after
receiving written notice of such breach from the non-breaching
party. If voluntary bankruptcy proceedings are instituted by a party under any federal, state or foreign insolvency laws, or if an involuntary petition is filed or executed against it and not
dismissed or satisfied within
                                      ; the other
party may, at its option, terminate this Agreement by written notice; provided, however, that all monies owed
hereunder prior to the date of termination shall be immediately due and payable. Airline may terminate this Agreement for cause in the event Orbitz is acquired and/or its ownership changes such that a
Competitor acquires a controlling interest in Orbitz. For purposes of this provision, "control" means the power to direct or cause the direction of the management and policies of Orbitz, whether
through the ownership of voting securities, by contract or otherwise. 

        17.3    Effect of Termination.    If this Agreement terminates or
expires for any reason, Airline will promptly pay Orbitz any undisputed amounts payable by Airline hereunder for Services rendered prior to the effective date of such termination. The provisions of
Sections 9, 11, 14, 15, 17, and 19 will survive the termination of this Agreement for any reason. In the event of any termination of this Agreement for any reason, the parties shall have no further
obligations hereunder other than those that expressly survive termination of this Agreement or are otherwise specified herein. 

18.    LEGAL STATUS.    Airline and Orbitz are independent parties. Nothing in this Agreement will be
construed to create any agency, employee, franchisee, joint venture, partnership or legal representative relationship between the parties. The parties expressly disclaim any such relationship, and
agree that the parties have no fiduciary duty to one another or any other special or implied duties that are not expressly stated herein. Orbitz is solely and exclusively responsible for the salaries,
wages, benefits, fees or other compensation that Orbitz, its Subcontractors or its or their agents or employees may be entitled to receive. 

19.    MISCELLANEOUS  

        19.1    Notices.    Any notice required or permitted under the terms
of this Agreement or required by law must be in writing and must be (a) delivered in person, (b) sent by first class registered mail, or air mail, as appropriate, (c) sent by
overnight air courier, or (d) sent by electronic mail (with a follow-up copy of such electronic mail message being sent by first class mail), in each case properly posted and fully
prepaid to the appropriate address set forth on the signature page of this Agreement. Either party may change its address for notice by notice to the other party given in accordance with 

19

 

this
Section 19.1. Notices will be considered to have been given as of the date received by the intended recipient. Notwithstanding the foregoing, in the case of notices required by
Section 5.1 or Section 5.15, or notices related to Network Services or Airline Host System outages as provided in the Specifications, notice sent by electronic mail shall be considered
to have been given as of the date sent and a follow-up copy of such electronic mail message shall not be required. Such communications will be sent to the address specified below or to any
other address that may be designated by prior notice.

        19.2    Waiver, Amendment and Modification.    Except as otherwise
provided above, any amendment or other modification of this Agreement will not be effective unless in writing and signed by the party against whom enforcement is sought. No waiver of breach of any
provision of this Agreement by either party will constitute a waiver of any subsequent breach of the same or any other provision, and no waiver will be effective unless made in writing and signed by
an authorized representative of the other party. 

        19.3    Severability.    If any provision of this Agreement is held to

labor strikes or difficulties, transportation stoppages or slowdowns or the inability to procure parts or materials. If any of these causes continue to

delaying party.

Schedule B
  Network Fees    
    

Orbitz
will invoice Airline on a monthly basis the following Network Fees: 

	•
	$                                      
Network Switching Fee for (i) each Supplier Link Ticket issued and (ii) each Airline or Codeshare Ticket issued
by or on behalf of any third party using the Network other than those issued through the Site, in each case, net of refunded, voided or exchanged Supplier Link Tickets or Airline / Codeshare Tickets,
as applicable, during the prior calendar month; and

	•
	$                                      
Network Incentive Fee for each Supplier Link Ticket issued, net of refunded, voided or exchanged Supplier Link Tickets issued
through the Site. 

        Airline
will pay Orbitz the Network Fees within thirty (30) days after receipt of Orbitz' invoice therefore. In the event that the Network Fees paid by Airline to Orbitz for any
year that this Agreement is in effect are less than
US$                                      , Airline
will pay Orbitz the difference between the aggregate Network Fees paid to Orbitz by Airline
and US$                                       within
forty-five (45) days of the Airline's receipt of the invoice from Orbitz. This amount will be prorated in the first year
and the last year of the term hereof and for any year during the term in which Airline did not incur
US$                                       in Network
Fees as a result of the failure of the
Network Services during any portion of such year. If Throttling results in Network Fees below
$                                      , then Airline
shall pay Orbitz the actual Network Fees
incurred and shall not be responsible for the minimum
$                                       set forth in
this paragraph. 

        In
addition to the per Supplier Link Ticket charges above, Airline will pay to Orbitz one-half of the actual costs incurred by Orbitz for the communications services that are
dedicated to Airline and are required for the interface between the Airline Host System and the Network servers for gathering Inventory information.
