applicable Delivery Point for Isobutylene Mix and Isobutane Return Stream. The
Parties shall cooperate to schedule deliveries of Feedstocks and Products for
such calendar quarter.

5. Supply of Feedstocks.

5.1. (a) To the extent XXXX requests conversion of Feedstocks to
Products hereunder, XXXX shall make all commercially reasonable efforts to
deliver Feedstocks on a reasonably uniform and consistent basis at the
applicable Delivery Point throughout each calendar month, and XXXX and EOTT will
coordinate to schedule the delivery of the Feedstocks in accordance with the
procedures and limitations of the relevant pipeline transporter(s) and loading
and unloading facilities. Notwithstanding the foregoing, if during any calendar
month the nominated amount of Feedstocks would result in a daily average
delivery of Products by EOTT to XXXX of less than 504,000 MTBE Equivalent
Gallons of Products per day, EOTT shall provide to XXXX a commercially
reasonable schedule for the delivery during such calendar month of the nominated
Feedstocks.

(b) With respect to deliveries of methanol, EOTT shall promptly notify
XXXX when the supply of methanol readily available for delivery falls below
300,000 gallons at the applicable Delivery Points, and to the extent XXXX is
then requiring conversion of Feedstocks into Products by EOTT under this
Agreement, XXXX shall use commercially reasonable efforts to maintain at least
210,000 gallons of methanol readily available for delivery. If EOTT has provided
such notice to XXXX and XXXX nevertheless fails to maintain at least 210,000
gallons of methanol readily available for delivery, then, to the extent, but
only to the extent, EOTT cannot convert Products as required by XXXX in
accordance with this Agreement as a direct result of an inadequate supply of
methanol, EOTT shall not be required to pay liquidated damages under Section
11.3 for the shortfall in Products caused thereby.

(c) With respect to deliveries of normal butane, EOTT shall promptly
notify XXXX when the supply of normal butane readily available for delivery

the applicable Delivery Points, and to the extent XXXX is then requiring
conversion of Feedstocks into Products by EOTT under this Agreement, XXXX shall
use commercially reasonable efforts to maintain at least 630,000 gallons of
normal butane readily available for delivery. If EOTT has provided such notice
to XXXX and XXXX nevertheless fails to maintain at least 630,000 gallons of
normal butane readily available for delivery, then, to the extent, but only to
the extent, EOTT cannot convert Products as required by XXXX in accordance with
this Agreement as a direct result of an inadequate supply of normal butane and
Isobutane Return Stream, EOTT shall not be required to pay liquidated damages
under Section 11.3 for the shortfall in Products caused thereby.

(d) All Feedstocks delivered to EOTT for conversion hereunder shall
meet the applicable Feedstocks specifications set forth on Schedule A attached
hereto; provided however, if any Feedstocks do not conform to such
specifications, EOTT shall promptly notify XXXX of such non-conformity and if so
requested by XXXX and allowed by regulation and law, shall convert such
Feedstocks to Products as commercially reasonable in accordance with this
Agreement. EOTT shall not be liable for any reduction in the quality of the
Products converted from such non-conforming Feedstocks, or for any contamination
of other Products, to the extent, but only to the extent, the reduction in
quality or contamination was caused by the nonconformity of the Feedstocks (such
permitted reduction in quality or excused contamination of other Products being
a "Permitted Product Quality Reduction"). Notwithstanding the foregoing, EOTT
shall not be obligated to accept and convert non-conforming Feedstocks if the
conversion of such non-conforming Feedstocks would damage a facility where the
conversion will occur or would be in violation of any applicable regulation or
law. If EOTT properly rejects any Feedstocks for such reason, then EOTT's sole
and exclusive remedy shall be to return such Feedstocks to XXXX at EGLI's
expense. XXXX shall not be liable for any claim regarding the quality or
quantity of any Feedstocks delivered or for any claim for damage to any facility
where the conversion occurs based upon the characteristics of the Feedstocks,
unless such claim has been submitted by EOTT to XXXX in writing, including
supporting documentation and reasonable details of the facts on which the claim
is based, within 90 days from the date of the certificate of quantity and
quality, certificate of pumping, confirmation of transfer, xxxx of lading, or
other document as appropriate to the specified delivery method. Should EOTT fail
to submit such claim or provide such documentation and details within this time
period, then such failure shall be deemed a waiver by EOTT of any claim and any
liability of XXXX for any such claim shall automatically be extinguished.
Nothing in this Section shall be deemed to impair EGLI's right to provide
substitute conforming Feedstocks for any non-conforming Feedstocks identified by
EOTT.

5.2. With respect to the supply of Feedstocks:

(a) For each gallon of MTBE that XXXX requests from EOTT
hereunder, XXXX shall make available to EOTT at the applicable
Delivery Point for conversion 1.00 gallons of normal butane and 0.345
gallons of methanol.

(b) For each gallon of isobutylene that XXXX requests from
EOTT hereunder, XXXX shall make available to EOTT at the applicable
Delivery Point for conversion 1.27

-9-

gallons of normal butane. For amounts Isobutylene Mix (other than
isobutylene) that XXXX requests from EOTT hereunder, XXXX shall make
available to EOTT at the applicable Delivery Point for conversion an
equal amount of normal butane (or Isobutane Return Stream).

(c) For every gallon of Regen Mix that XXXX is required to
take from EOTT hereunder in accordance with Section 6.2, XXXX shall
make available to EOTT at the applicable Delivery Point for conversion
an equal amount of normal butane.

(d) For each amount of PP Mix that XXXX requests from EOTT
hereunder, XXXX shall make available to EOTT at the applicable Delivery
Point for conversion an equal amount of natural gas, on an MMBtu basis.

(e) Regardless of the amount of Products that XXXX requests
from EOTT hereunder, XXXX shall supply to EOTT 6,000 MMBtus of natural
gas each day during the term of this Agreement. For each MTBE
Equivalent Gallon of MTBE or isobutylene in excess of the Minimum
Quarterly Conversion that XXXX requests from EOTT hereunder, XXXX shall
make available to EOTT at the applicable Delivery Point for conversion
an additional 0.009 MMBtus of natural gas.

Except as specified above, XXXX shall not be required to supply any
Feedstocks in order to receive Products requested from EOTT hereunder,
including By-Products.

5.3. To the extent EOTT needs Feedstocks in excess of the amounts
required under Section 5.2 in order to convert and make available the amount of
Products as required by XXXX in accordance with this Agreement, EOTT may (a)
purchase additional Feedstocks for its own account and provide Products as
required hereunder, (b) to the extent made available by XXXX, use such
additional Feedstocks and pay to XXXX in accordance with Section 11.4(b) an
amount equal to the amount of such additional Feedstocks multiplied by the
applicable Feedstock Market Price for such Feedstocks (and XXXX shall be deemed
to have made additional Feedstocks available to EOTT to the extent XXXX delivers
such Feedstocks to or stores such Feedstocks with EOTT, unless XXXX notifies
EOTT otherwise), or (c) to the extent additional Feedstocks are not converted to
provide the required amount of Products, pay liquidated damages for failure to
deliver Products in accordance with Section 11.3. To the extent EOTT converts
and makes available the amount of Products as required by XXXX in accordance
with this Agreement and utilizes less Feedstocks than XXXX is required by
Section 5.2 to make available to EOTT for such conversion, XXXX shall pay to
EOTT an amount equal to the amount of Feedstocks required to be made available
but not utilized by EOTT in converting the amount of Products required by XXXX
in accordance with this Agreement multiplied by the applicable Feedstock Market
Price for such Feedstocks. Nothing in this Section 5.3 shall obligate XXXX to
make available to EOTT Feedstocks in an amount greater than the amounts required
by Section 5.2.

in Products delivered by EOTT to XXXX in accordance with this Agreement while
risk of loss is held by EOTT, whether by processing inefficiency, casualty,
force majeure, or otherwise, EOTT shall either (a) replace such Feedstocks

XXXX hereunder or under any other agreements with EOTT

-12-

and no delay in enforcing the foregoing shall act as a waiver of EGLI's rights
hereunder or thereunder.

(d) Provided that EOTT complies with the foregoing and does not impair
EGLI's title to Feedstocks, goods-in process resulting therefrom, or Products,
EOTT shall have the right to effectuate conversion of EGLI's Feedstocks at third
party facilities, but use of such third party facilities shall not release EOTT
from any of its obligations hereunder. Further, in the event that EOTT can not
convert or can not cause the conversion of Feedstocks into Products, EOTT may,
with EGLI's consent, which shall not be unreasonably withheld, sell the
applicable amount of Feedstocks required for conversion into Products hereunder
and purchase such Products on the open market for delivery to XXXX for the
purposes of complying with EOTT's obligations under this Agreement.

8. Measuring Quantity and Quality.

8.1. Inspector. EOTT shall appoint a licensed independent inspector,
reasonably acceptable to XXXX, to verify the quantity of all Feedstocks and
Products delivered at the applicable Delivery Point. The total cost of such
independent inspector at the applicable Delivery Point shall be shared equally
between EOTT and EGLL The quality of all Feedstocks and Products shall be tested
by EOTT at EOTT's expense and the results of such testing shall be delivered to
XXXX within five (5) days of discharge or delivery and shall be final and
binding on both EOTT and XXXX, absent fraud or manifest error. Should either
Party reasonably request any additional testing of quality by an independent
third party, the cost of such independent testing shall be borne by the
requesting Party.

8.2. Standards. All measurements and tests for quantity and quality
shall be made in accordance with the standard measuring, sampling, and other
testing procedures in effect for such Feedstocks and Products at the Delivery
Point at the time of delivery. Volumes shall be corrected to 60 degrees
Fahrenheit and converted into gallons in accordance with the latest ASTM-IP test
methods and the latest edition of API volume correction factors then in effect.
Both Parties may have a representative present at the applicable Delivery Point
to witness all measurements and tests.

8.3. Quantity. With respect to Feedstocks delivered by Vessel and
Products delivered to Vessel, the independent inspector shall gauge and record
inactive shore tank measurements immediately before and immediately after the
unloading of Feedstocks or the loading of Products to determine the volume
unloaded or loaded (adjusted for slack volume in shorelines, if any), or by
meters, if meters are available. With respect to Feedstocks or Products
delivered by pipeline, the volume delivered will be determined through meters or
by measuring storage tanks from or to which delivery is made.

8.4. Quality. With respect to Feedstocks delivered by Vessel,
representative samples will be drawn from either the unloading line or from the
Vessel from which delivery is made. With respect to Products delivered to
Vessel, representative samples will be drawn either from the loading line or
from the shore tanks from which delivery is made. With respect to Feedstocks

-13-

or Products delivered by pipeline, representative samples will be drawn either
from the delivery line or from the storage tanks from which delivery is made.

8.5. Products Claims. With respect to the delivery of Products,
including Products converted from non-conforming Feedstocks in accordance with
Section 5.1, EOTT shall not be liable for any claim regarding the quality or
quantity of any Products delivered, unless such claim has been submitted by XXXX
to EOTT in writing, including supporting documentation and reasonable details of
the facts on which the claim is based, within 90 days from the date of the
certificate of quantity and quality, certificate of pumping, confirmation of
transfer, xxxx of lading, or other document as appropriate to the specified
delivery method. Should XXXX fail to submit such claim or provide such
documentation and details within this time period, then such failure shall be
deemed a waiver by XXXX of any such quantity or quality claim and any liability
of EOTT for any such claim shall automatically be extinguished.

9. Rejection Rights. If EOTT delivers to XXXX Products that do not
conform to the quality specifications set forth on Schedule B or, with respect
to Products subject to a Permitted Product Quality Reduction in accordance with
Section 5.1, to such quality specifications as are required therefor, or are
otherwise defective (the "Non-Conforming Products"), XXXX shall be entitled to
request a reduction in the Conversion Fee applicable to such Non-Conforming
Products by an amount that reflects the decreased value of such Non-Conforming
Products, as agreed to by the Parties. If the Parties are unable to agree to the
amount of such reduction within 48 hours after EGLI's request for such
reduction, no reduction in Conversion Fees shall be effected but at the close of
the applicable calendar quarter, XXXX shall be entitled to payment by EOTT of
liquidated damages in an amount determined by the following formula:

Liquidated Damages for Non-Conforming Products = NCP x MTBEMP
q q q
- RV
q

Where:

NCP = The quantity of Non-Conforming Products in MTBE
q Equivalent Gallons for which a reduction in
Conversion Fees was not agreed to during calendar
quarter q (expressed in gallons)

MTBEMP = The MTBE Market Price for calendar quarter q
q (expressed in $ per gallon)

RV = The Resale Value for the Non-Conforming Products
q for which a reduction in Conversion Fees was not
agreed to during calendar quarter q, if any, which
was actually obtained or could have been obtained by
XXXX upon resale to third parties at any time
selected by XXXX during calendar quarter q, as
determined by XXXX in a commercially reasonable
manner (expressed in $)

(For purposes of illustration only, a sample calculation is provided on Schedule
D attached hereto.)

-14-

Notwithstanding the foregoing, XXXX shall not be obligated to accept
Non-Conforming Products if such Non-Conforming Products would damage any
facilities that would transport, store, or use such Products, unless such
Non-Conforming Products directly result from the conversion of non-conforming
Feedstocks which XXXX requires EOTT to convert in accordance with Section 5.1.
If XXXX properly rejects any Products for such reason, then EOTT, after
discussion with XXXX, shall dispose of such Products at EOTT's expense and shall
pay any liquidated damages for failure to convert Products in accordance with
Section 11.3 and any payments for additional Feedstocks in accordance with
Section 5.3.

10. Option for Conversion of other Products.

10.1. At any time during this Agreement, XXXX shall have the option to
require EOTT, subject to the terms below, to enter into an amendment and
restatement of this Agreement providing for an adjustment of the Products to
isooctane, isobutylene, isobutane or any other set of products (the "New
Products") that XXXX may reasonably request and a corresponding change in
Feedstocks (the "New Feedstocks"). To the extent owned by EOTT, XXXX shall have
the right to access Xxxxxx'x Point to determine whether or not to exercise the
option and conduct preliminary engineering regarding the same. Upon notification
to EOTT of EGLI's intent to exercise this option (the "New Agreement
Notification"), an independent engineering firm, mutually agreed to by the
Parties, will be appointed to prepare a turnkey construction contract bid
containing market based commercially reasonable performance guarantees to
convert Xxxxxx'x Point or another facility mutually agreed to by the Parties
(the "New Agreement EPC Proposal") and the parties will prepare an amendment and
restatement of this Agreement (the "New Agreement") subject to the terms below.
If during any calendar quarter between the New Agreement Notification and the
New Agreement Effective Date, as defined below, EOTT is unable to deliver an
amount of Products at least equal to the Minimum Quarterly Conversion under this
Agreement, and such failure is due to events caused by EGLI's exercise of its
option, then XXXX shall nevertheless be required to pay to EOTT for such
calendar quarter the Conversion Fee for an amount of Products equal to the
applicable Minimum Quarterly Conversion.

10.2. The Conversion Fee under the New Agreement will be adjusted (the
"Adjusted Conversion Fee") to be effective as of the date of first delivery of
the New Feedstocks to EOTT, as mutually agreed to by the Parties (the "New
Agreement Effective Date"). The Adjusted Conversion Fee will be a stated amount
calculated to reflect (1) a market rate of return to EOTT consistent with this
Agreement on the sum of (a) the cost to convert Xxxxxx'x Point or the facility
agreed to by the Parties as obtained in the New Agreement EPC Proposal plus any
additional costs to convert, including but not limited to, direct costs, testing
costs and feedstock costs related to testing, and (b) the termination amount
that would have been due under Section 14 of this Agreement as of the New
Agreement Effective Date less $20,000,000, and (2) commercially reasonable
operating and maintenance costs for the facility as determined by an independent
third party. The Parties to this Agreement recognize that the specific terms
defining the Adjusted Conversion Fee are subject to further analysis; however,
the Parties agree that the risks and rewards of the New Agreement shall be
consistent with this Agreement. The Adjusted Conversion Fee will be paid by XXXX
on terms consistent with this Agreement. Liquidated

-15-

damages for EOTT's failure to convert the New Feedstocks into New Products under
the New Agreement will be calculated in a manner consistent with the provisions
under this Agreement. The initial term of the New Agreement will be ten years
from the New Agreement Effective Date.

10.3. EOTT may satisfy its obligations under the New Agreement without
actually converting Xxxxxx'x Point or any other facility.

11. Conversion Fee and Terms of Payment.

11.1. Conversion Fee. For each calendar quarter, XXXX shall pay to EOTT
(a) for each MTBE Equivalent Gallon of Products (other than By-Products) up to
the applicable Minimum Quarterly Conversion delivered by EOTT hereunder and made
available to XXXX, a fee equal to the applicable Conversion Fee and (b) for each
MTBE Equivalent Gallon of Products (other than By-Products) in excess of the
applicable Minimum Quarterly Conversion delivered by EOTT hereunder and made
available to XXXX, a fee equal to the Excess Conversion Fee. Notwithstanding any
other provision of this Agreement, no Conversion Fee, liquidated damages,
termination amounts, or other consideration hereunder (except for supply of
Feedstocks in accordance with Section 5.2) shall be due to EOTT with respect to
By-Products.

11.2. Unavailability of Feedstocks. During any calendar quarter, if (a)
XXXX does not request conversion of Feedstocks into Products (other than
By-Products) in an amount at least equal to the applicable Minimum Quarterly
Conversion, (b) XXXX fails to deliver adequate quantities of Feedstocks in
accordance with Section 5.1 for conversion into such Products in an amount at
least equal to the applicable Minimum Quarterly Conversion for any reason, or
(c) EOTT cannot convert Feedstocks into such Products in an amount at least
equal to the applicable Minimum Quarterly Conversion as a result of EGLI's
failure to accept such Products in accordance with Section 6.2, XXXX shall
nevertheless be required to pay to EOTT for such calendar quarter the Conversion
Fee for an amount of such Products equal to the applicable Minimum Quarterly
Conversion. The matters described in clauses (a) through (c) shall not
constitute "Event of Default" hereunder, and timely payment of such amount shall
be EOTT's sole and exclusive remedy with respect thereto.

11.3. Liquidated Damages for Failure to Convert. For any calendar
quarter, to the extent XXXX requests conversion of Feedstocks into Products
(other than By-Products) and has made available sufficient Feedstocks in
accordance with the terms of this Agreement, if EOTT fails, whether due to force
majeure or otherwise, to convert Feedstocks and make available such Products, or
otherwise make available such Products in accordance with Section 7.5(d), EOTT
shall pay to XXXX liquidated damages calculated as follows for the amount of
such Products not made available up to the Minimum Quarterly Conversion (such
Products not made available during such calendar quarter up to the Minimum
Quarterly Conversion being the "Deficiency"):

-16-

Liquidated Damages = D x [MTBEMP -- ((Sigma)(YF x FSMP ) + CF )]
q q q f fq q

Where:

D = Deficiency in MTBE Equivalent Gallons during
q calendar quarter q (expressed in gallons)

MTBEMP = MTBE Market Price for calendar quarter q
q (expressed in $ per gallon)

(Sigma)(YF x FSMP ) = The sum of the products of YFf and FSMPfq for the
f fq Feedstocks normal butane and methanol for calendar
quarter q

YF = The Yield Factor for Feedstock f (expressed in
f gallons per gallon)

FSMP = The Feedstock Market Price for Feedstock f during
fq calendar quarter q (expressed in $ per gallon)

CF = The Conversion Fee applicable to calendar quarter q
q (expressed in $ per gallon)

(For purposes of illustration only, a sample calculation is provided
on Schedule D attached hereto.)

Except as otherwise provided in Section 13.1(v), any such failure
shall not itself constitute an "Event of Default" hereunder, and timely payment
of such amount shall be EGLI's sole and exclusive remedy with respect to
thereto. To the extent EOTT fails to provide to XXXX all available By-Products
resulting from the conversion of Feedstocks into Products under this Agreement,
EOTT shall pay to XXXX actual damages.

11.4. Invoices and Payments.

(a) For each calendar month during the Term of this Agreement, no
later than the 15th" day of the calendar month immediately following such
calendar month, EOTT shall provide to XXXX an invoice for Conversion Fees in an
amount equal to the product of the applicable Conversion Fee and 1/3rd of the
applicable Minimum Quarterly Conversion. No later than 5 days after receipt of
such invoice, XXXX shall pay the amount set forth on such invoice.

(b) For each calendar quarter during the Term of this Agreement, no
later than the 15th day of the calendar month immediately following such
calendar quarter, each Party shall provide the other Party, if necessary, with
an invoice setting forth, as appropriate,

(i) the applicable Conversion Fee payable by XXXX for all
Products actually delivered and made available at
each Delivery Point owed under Section

-17-

11.1(a), or otherwise payable under Section 11.2,
during the previous calendar quarter for which
payment has not already been invoiced and made
pursuant to paragraph (a) above (or if the amounts
paid under paragraph (a) above exceed the amounts
owed under Section 11.1(a) and 11.2, the refund owed
by EOTT);

(ii) the amount payable by XXXX, if any, with respect to
the Excess Conversion Fees in accordance with Section
11.1(b);

(iii) the amount payable by EOTT, if any, for agreed upon
reductions in Conversion Fees for Non-Conforming
Products in accordance with Section 9;

(iv) any reimbursement owed by either Party for the costs
of the independent inspector in accordance with
Section 8 or for taxes in accordance with Section 19;

(v) the amount payable by either Party, if any, in
accordance with Section 5.3;

(vi) the liquidated damages payments, if any, payable by
either Party in accordance with Sections 9 and 11.3;
and

(vii) the amount payable by XXXX, if any, with respect to
the EOTT Excess Fee in accordance with Section 12.

No later than 5 days after receipt of a Party's invoice, the receiving
Party shall pay the amount set forth on such invoice.

(c) Each Party shall provide the other Party from time to time, if
necessary, with an invoice setting forth any other amounts payable under this
Agreement not discussed in paragraphs (a) or (b) above. Such payments shall be
due as set forth in this Agreement, but if any due date is not set forth in this
Agreement, then not later than 10 days after receipt of the invoice.

(d) All payments due shall be made by wire transfer in immediately
available United States funds to the applicable payment address and account
specified by the payee. If any payment is due on a date other than a business
day, the payment shall be due on the following business day.

(e) In the event of any dispute as to any portion of an invoice, the
Party disputing the invoice shall pay the undisputed amounts in full at the time
such payment should be made in accordance with this Agreement and shall notify
the other Party of the portion of the invoice in dispute, in which case the
Parties shall discuss the invoice within 5 days in an attempt to resolve the
dispute, but if such discussion does not resolve the dispute then the provisions
of Section 20.2 shall apply. The resolution of the disputed amount shall include
interest at the Interest Rate.

-18-

(f) Any payments not made when due shall bear interest, from the date
such payment is due until paid in full, at the Interest Rate.

11.5. Netting and Setoff. If the Parties are each required to pay any
amount on the same day or in the same month, then such amounts with respect to
each Party shall be aggregated and the Parties may discharge their obligations
to pay through netting, in which case the Party, if any, owing the greater
aggregate amount may pay to the other Party the difference between the amounts
owed. Each Party reserves to itself all rights, setoffs, counterclaims,
combination of accounts, liens, and other remedies and defenses which such Party
has or may be entitled to (whether by operation of law or otherwise). The
obligations to make payments under this Agreement may be offset against each
other, set off, or recouped therefrom.

11.6. Credit Support. If at any time the EOTT Guarantor has an
Unacceptable EOTT Credit Rating or no Credit Rating, then within 5 days after
the occurrence of such circumstance and as long as such circumstance shall
exist, at EGLI's request, EOTT shall cause to be issued and maintained for the
benefit of XXXX an irrevocable letter of credit in an amount reasonably
requested by XXXX not to exceed $25,000,000, having an effective period of one
year, issued by a bank reasonably acceptable to XXXX, and otherwise having terms
and conditions reasonably acceptable to XXXX. The letter of credit may be drawn
upon by XXXX if EOTT fails to pay any amount owed to XXXX hereunder. In the
event the letter of credit is drawn to satisfy any of EOTTs obligations, EOTT
shall promptly, but in no event more than 5 days following the date that the
letter of credit is drawn, restore the letter of credit to its original amount.
The letter of credit may be drawn upon in part or in full by XXXX if EOTT fails
to maintain the letter of credit as required or EOTT fails to renew the letter
of credit at least 20 days prior to its expiration, in which case XXXX may hold
the proceeds thereof for application from time to time for the obligations of
EOTT under this Agreement until the letter of credit is restored, in each case
without limiting EOTT's obligation to maintain the letter of credit as required
or any Event of Default applicable thereto.

If at any time the XXXX Guarantor has an Unacceptable XXXX Credit
Rating or no Credit Rating, then within 5 days after the occurrence of such
circumstance and as long as such circumstance shall exist, at EOTT's request,
XXXX shall cause to be issued and maintained for the benefit of EOTT an
irrevocable letter of credit in an amount reasonably requested by EOTT not to
exceed $25,000,000, having an effective period of one year, issued by bank
reasonably acceptable to EOTT, and otherwise having terms and conditions
reasonably acceptable to EOTT. The letter of credit may be drawn upon by EOTT if
XXXX fails to pay any amount owed to EOTT hereunder. In the event the letter of
credit is drawn to satisfy any of EGLI's obligations, XXXX shall promptly, but
in no event more than 5 days following the date that the letter of credit is
drawn, restore the letter of credit to its original amount. The letter of credit
may be drawn upon in part or in full by EOTT if XXXX fails to maintain the
letter of credit as required or XXXX fails to renew the letter of credit at
least 20 days prior to its expiration, in which case EOTT may hold the proceeds
thereof for application from time to time for the obligations of XXXX under this
Agreement until the letter of credit is restored, in each case without limiting
EGLI's obligation to maintain the letter of credit as required or any Event of
Default applicable thereto.

-19-

12. Excess Products Delivery. For any calendar quarter during each Excess
Production Period, if EOTT delivers and makes available to XXXX Products (other
than By-Products) in excess of the applicable Minimum Quarterly Conversion
("Excess Products"), XXXX shall, within 15 days after each calendar quarter,
calculate an amount ("Excess Fee") determined by the following formula:

Excess Fee = EP x [MTBEMP - (ECF + (Sigma(YF x FSMP )]
q q q q f fq
Where:

EP = The Excess Products in MTBE Equivalent Gallons for
q calendar quarter q (expressed in gallons)

MTBEMP = The MTBE Market Price for calendar quarter q
q (expressed in $ per gallon)

ECF = The Excess Conversion Fee for calendar quarter q
q (expressed in $ per gallon)

Sigma(YF x FSMP = The sum of the products of YFf and FSMPfq for the
f fq Feedstocks normal butane and methanol for calendar
quarter q

YF = The Yield Factor for Feedstock f (expressed in
f gallons per gallon)

FSMP = The Feedstock Market Price for Feedstock f during
fq calendar quarter q (expressed in $ per gallon)

(For purposes of illustration only, a sample calculation is provided
on Schedule D attached hereto.)

The positive Excess Fee, if any, for each calendar quarter shall be
allocated among EOTT ("EOTT Excess Fee") and XXXX in accordance with this
Section, and XXXX shall pay to EOTT the EOTT Excess Fee as so allocated at the
end of each calendar quarter. For any calendar quarter during each Excess
Production Period: (a) EOTT shall be allocated 90% of any Excess Fee until the
cumulative EOTT Excess Fee for such Excess Production Period is equal to
$2,500,000; (b) thereafter, for additional Excess Fees, EOTT shall be allocated
50% of any Excess Fee until the cumulative EOTT Excess Fee for such Excess
Production Period is equal to $5,000,000; and (c) thereafter, for additional
Excess Fees, EOTT shall be allocated 25% of any Excess Fee. In no event shall
any negative Excess Fee be allocated to EOTT.

-20-

13. Events of Default, Remedies and Limitation of Liability.

13.1. Events of Default. An event of default ("Event of Default") with
respect to a Party (the "Defaulting Party") shall mean any of the following: (i)
the failure of Defaulting Party to pay when due any required payment under this
Agreement and such failure is not remedied within 5 days after written notice
thereof; (ii) the failure of the Defaulting Party to comply with its other
respective obligations under this Agreement and such failure continues uncured
for 30 days after written notice thereof; (iii) the Defaulting Party shall be
subject to a Bankruptcy Proceeding; (iv) any representation or warranty made by
a Party under this Agreement shall prove to be untrue or misleading in any
material respect when made or repeated or deemed to have been made or repeated;
(v) with respect to EOTT, and provided Feedstocks are provided in accordance
with this Agreement, EOTT's failure to deliver or delivery of non-conforming
Products that have been requested by XXXX in accordance with this Agreement in
an amount exceeding 50% of the applicable Minimum Quarterly Conversion during
any 4 out of 8 consecutive calendar quarters during the first two Contract
Years, or 50% of the applicable Minimum Quarterly Conversion during any 2 out of
4 consecutive calendar quarters thereafter, in each case for reasons other than
force majeure; (vi) with respect to EOTT, the EOTT Guarantor shall give notice
to revoke or revoke the EOTT Guaranty or challenge the EOTT Guaranty, the EOTT
Guaranty shall cease to be in full force and effect, the EOTT Guarantor shall
breach its obligations under the EOTT Guaranty, the EOTT Guarantor shall be
subject to a Bankruptcy Proceeding, or any representation or warranty made by
the EOTT Guarantor in the EOTT Guaranty shall prove to be untrue or misleading
in any material respect when made or repeated or deemed to have been made or
repeated; (vii) with respect to XXXX, the XXXX Guarantor shall give notice to
revoke or revoke the XXXX Guaranty or challenge the XXXX Guaranty, the XXXX
Guaranty shall cease to be in full force and effect, the XXXX Guarantor shall
breach its obligations under the XXXX Guaranty, the XXXX Guarantor shall be
subject to a Bankruptcy Proceeding, or any representation or warranty made by
the XXXX Guarantor in the XXXX Guaranty shall prove to be untrue or misleading
in any material respect when made or repeated or deemed to have been made or
repeated; (viii) with respect to EOTT, any default, event of default,
termination event, or other similar condition or event (however described) shall
occur or exist under any other Transaction Agreement with respect to EOTT or the
EOTT Guarantor provided that any applicable grace or cure periods have expired;
or (ix) with respect to XXXX, any default, event of default, termination event,
or other similar condition or event (however described) shall occur or exist
under any other Transaction Agreement with respect to XXXX or the XXXX Guarantor
provided that any applicable grace or cure periods have expired.

Upon the occurrence and during the continuation of an Event of Default
as to the Defaulting Party, the other Party (the "Non-Defaulting Party") may, in
its sole discretion, (a) accelerate and liquidate the Parties' respective
obligations under this Agreement by establishing, and notifying the Defaulting
Party of, an early termination date (which shall be no earlier than the date of
such notice and no later than 90 days after the date of such notice) on which
this Agreement shall terminate ("Early Termination Date"), (b) withhold any
payments due to the Defaulting Party until such Event of Default is cured, or
(c) set off against any amounts due to the Defaulting Party any or all amounts
which the Defaulting Party owes to the Non-Defaulting Party (without prejudice
and in addition to any right of setoff, combination of accounts, lien, or other
right to which the Non-Defaulting Party is at any time otherwise entitled
(whether by

-21-

operation of law, contract, or otherwise)). If notice of an Early Termination
Date is given under this Section 13.1, the Early Termination Date will occur on
the designated date, whether or not the relevant Event(s) of Default is then
continuing. Any rights of a Non-Defaulting Party under this Section 13.1 shall
be in addition to such Non-Defaulting Party's other rights under this Agreement,
at law or in equity.

13.2. Early Termination Amount.

(a) If an Early Termination Date is established, and the Defaulting
Party is EOTT, XXXX shall in good faith calculate its Gains, Losses, and Costs
resulting from the termination of this Agreement, and then notify EOTT of the
net amount owed or owing, not to exceed an amount owed by EOTT equal to the
amount calculated in accordance with Schedule F attached hereto for the calendar
quarter in which this Agreement terminates pursuant to this Section 13.2 (the
"EOTT Payment Limit"). In determining Gains and Losses for such purpose, XXXX
shall (i) use published forward price curves for the market price of Products
and Feedstocks to the extent available, and, to the extent published forward
price curves are not available, forward price curves for the market price of
Products and Feedstocks as developed by an independent third party which has
experience in evaluating forward price curves for Feedstocks and Products,
mutually agreed to by the Parties, and (ii) determine the present value of any
future amounts using a discount rate of 14%. If EGLI's aggregate Losses and
Costs exceed its aggregate Gains, EOTT shall, within five (5) days of its
receipt of such notice, pay the net amount to XXXX, subject to the EOTT Payment
Limit. If EGLI's aggregate Gains exceed its aggregate Losses and Costs resulting
from such early termination, EOTT shall have no payment obligation under this
Section.

(b) If an Early Termination Date is established, and the Defaulting
Party is XXXX, EOTT shall in good faith calculate its Gains, Losses, and Costs
resulting from the termination of this Agreement, and then notify XXXX of the
net amount owed or owing, not to exceed an amount owed by XXXX equal to the
present value of a payment stream equal to the applicable Minimum Quarterly
Conversion multiplied by the Conversion Fee at the time of the determination for
each of the calendar quarters which would have been remaining in the Term of
this Agreement but for the establishment of an Early Termination Date (such
present value amount being the "XXXX Payment Limit"). In determining Gains and
Losses for such purpose, EOTT shall determine the present value of any future
amounts using a discount rate of 14% and such Losses shall exclude any amounts
related to the permanent shut down of the facilities or termination of long-term
contracts EOTT has used to convert Products hereunder, but shall include
$20,000,000 for general damages. if EOTT's aggregate Losses and Costs exceed its
aggregate Gains, XXXX shall,. within five (5) days of its receipt of such
notice, pay the net amount to EOTT, subject to the XXXX Payment Limit, unless
XXXX then elects to voluntarily terminate this Agreement in accordance with
Section 14, in which case the provisions of Section 14 shall control. if EOTT's
aggregate Gains exceed its aggregate Losses and Costs resulting from such early
termination, XXXX shall have no payment obligation under this Section.

(c) In either case, the Non-Defaulting Party shall determine its Gains,
Losses, and Costs as of the Early Termination Date, or, if that is not possible,
at the earliest date thereafter that is reasonably possible.

-22-

13.3. Damages Stipulation. Each Party stipulates that the payment
obligations set forth in this Agreement, including in Sections 9, 11.2, 11.3,
and 13.2, for the damages incurred are a reasonable approximation of the
anticipated harm or loss and acknowledges the difficulty of estimation or
calculation of actual damages, and each Party hereby waives the right to contest
such payments as unenforceable, an unreasonable penalty, or otherwise.

13.4. Expenses. The Defaulting Party will, on demand, reimburse,
indemnify, and hold harmless the Non-Defaulting Party for and against all
reasonable out-of-pocket expenses, including Legal Costs, incurred by the
Non-Defaulting Party in the enforcement and protection of its rights under this
Agreement by reason of an Event of Default, including costs of collection.

13.5. Limitation of Liability. THE PARTIES CONFIRM THAT THE EXPRESS
REMEDIES AND MEASURES OF DAMAGES PROVIDED IN THIS AGREEMENT INCLUDING IN
SECTIONS 9, 11.2, 11.3, AND 13.2, SATISFY THE ESSENTIAL PURPOSES HEREOF. FOR
BREACH OF ANY PROVISION FOR WHICH AN EXPRESS REMEDY OR MEASURE OF DAMAGES IS
HEREIN PROVIDED, SUCH EXPRESS REMEDY OR MEASURE OF DAMAGES SHALL BE THE SOLE AND
EXCLUSIVE REMEDY, THE LIABLE PARTY'S LIABILITY SHALL BE LIMITED AS SET FORTH IN
SUCH PROVISION AND ALL OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED
UNLESS OTHERWISE PROVIDED IN THIS AGREEMENT. IF NO REMEDY OR MEASURE OF DAMAGES
IS EXPRESSLY HEREIN PROVIDED, THE LIABLE PARTY'S LIABILITY SHALL BE LIMITED TO
DIRECT ACTUAL DAMAGES ONLY. EXCEPT TO THE EXTENT SET FORTH IN AN EXPRESS REMEDY
OR MEASURE OF DAMAGES, NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR
CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY OR INDIRECT DAMAGES, LOST PROFITS
OR BUSINESS INTERRUPTION DAMAGES, WHETHER BY STATUTE, IN TORT OR IN CONTRACT,
UNDER OR RELATED TO THIS AGREEMENT, INCLUDING UNDER ANY INDEMNITY PROVISION OR
OTHERWISE.

14. Voluntary Termination. At any time beginning after the end of the third
Contract Year, upon written notice to EOTT given at any time before a New
Agreement has become effective, XXXX may voluntarily terminate this Agreement
under this paragraph beginning on a date selected by XXXX that is 90 days or
more after such notice is given. At any time when an Early Termination Date is
established and the Defaulting Party is XXXX, upon written notice to EOTT given
at any time before a New Agreement has become effective, XXXX may voluntarily
terminate this Agreement under this paragraph on such Early Termination Date.
Upon termination pursuant to this paragraph, XXXX shall pay to EOTT an amount
equal to the amount listed on Schedule E attached hereto for the calendar
quarter in which this Agreement terminates pursuant to this paragraph.

15. Force Majeure. Except to the extent provided in Section 13.1(v), force
majeure or shutdown of any facilities shall not be an excuse for either Party's
obligations hereunder or any Event of Default hereunder, and each Party hereby
irrevocably waives any right to claim excuse hereunder for the same.

-23-

16. Indemnity.

16.1. EOTT shall indemnify, defend, and hold harmless XXXX from and
against any and all losses, claims, demands, penalties, liability, suits,
damages, judgments, costs, or expenses (including costs of defense, settlement,
and reasonable attorney's fees) arising out of or related to (a) Any injury or
death of persons or damage to property caused by or happening in connection with
EOTT's storage or conversion operations hereunder unless and to the extent that
the same is caused by EGLI's gross negligence or willful misconduct; (b)
infringement or claimed infringement of U.S. patents by virtue of the methods or
processes employed by EOTT's conversion of EGLI's Feedstocks or employed by
third parties for the production of Products for supply to XXXX (c) any claims
whatsoever by any third party (including without limitation, any governmental
agency or instrumentality) arising out of, related to, or in connection with any
acts or omissions of EOTT regarding the operation of Xxxxxx'x Point and in
particular (i) any corrective action required to be taken pursuant to the
Resource Conservation and Recovery Act or the state equivalent to address any
release of any contaminating or hazardous substance; (ii) the cost of removing
from the Xxxxxx'x Point any waste material; and (iii) any contamination or

16.2. EOTT, its successors and assigns hereby waive and release and
agree not to make any claim against or seek recovery from XXXX including any
recovery claim under CERCLA or any state or local equivalent against XXXX for
the deficiencies against which EOTT has agreed to indemnify XXXX herein.

17. Insurance. EOTT shall obtain and maintain in full force and effect property,
liability, and business interruption insurance in amounts adequate to insure
against any loss or damage associated with its control and possession of the
Feedstocks, goods-in-process resulting therefrom, and Products, including damage
to property, injury and/or death to persons, contractual liabilities for
indemnities under this Agreement, and environmental liabilities. Such insurance
policies shall (a) provide that such insurance shall not be canceled by the
insurance carrier unless 30 days prior notice has been given to XXXX, (b) be
primary and non-contributory to any insurance maintained by XXXX, (c) be
endorsed to name XXXX as an additional insured and to waive all rights of
subrogation against XXXX, and (d) be issued by insurance companies reasonably
satisfactory to XXXX. Without creating any obligation or right of XXXX, the XXXX
Guarantor, or another party to provide the required insurance for EOTT, and
without limiting EOTT's obligation with respect to the required insurance
hereunder, this requirement may be satisfied to the extent a third party
provides such insurance on behalf of EOTT at EOTT's cost.

18. Audit Rights. Each Party (and its representatives) has the right, at its
sole expense during normal working hours and upon reasonable advance notice, to
examine the records of the other Party, but only to the extent reasonably
necessary to verify the accuracy of any statement, charge, or computation made
pursuant to this Agreement. If requested, a Party shall provide to the other
Party inventory and conversion reports and statements for the two-year period
preceding the audit date evidencing the quantities of Feedstocks or Products
delivered or received at the Delivery Point(s). If any such examination reveals
any inaccuracy in any

-24-

statement, the necessary adjustments in such statements and the payments thereof
will be promptly made and shall bear interest calculated at the Interest Rate
from the date the overpayment or underpayment was made until paid; provided,
however, that no adjustment for any statement or payment will be made unless
objection to the accuracy thereof was made prior to the lapse of two years from
the rendition thereof; and provided further, that for the purpose of such
statement and payment objections, this Section will survive any termination of
this Agreement.

19. Taxes. Each Party shall be responsible for taxes imposed on its revenues and
profits from its activities hereunder and each Party's ownership, if any, of the
Feedstocks, goods-in-process resulting therefrom, Products, and the property it
owns, including Xxxxxx'x Point.

20. Miscellaneous.

provides a guaranty by a financially responsible party upon substantially the
same terms and conditions as the XXXX Guaranty, and (b) the rights and
obligations of EOTT under this Agreement may be assigned and delegated to any
wholly owned subsidiary of EOTT or the EOTT Guarantor, in each case without the
prior written consent of XXXX. All covenants, terms, conditions, and provisions
of this Agreement shall be binding upon the Parties hereto and shall extend to
