member of the ACC Group a continuing security interest in and first lien on, and a right of setoff
with respect to, all of their respective securities, notes, mortgages, instruments, financial
assets, monies, trust receipts or other property whenever acquired and all distributions thereon

and performance of any and all present and future obligations and liabilities of each member of the

or otherwise (including without limitation obligations and liabilities under any Transactions),
whether matured, unmatured, liquidated, unliquidated, fixed or contingent (together with interest
at the rate provided under any agreement evidencing the same (or if not so provided, at the rate
described in Section 5(c)), and any allowed costs and fees, the “Obligations”).

B. All property of the Luminent Group held by the ACC Group shall be held in the nature of a
deposit for security. Except to the extent otherwise expressly provided in a Transaction Document,
Collateral held by or for the benefit of, or pledged to any member of the ACC Group, shall be
deemed held by or for the benefit of, or pledged to, such entity for its own account or as agent
and/or custodian for the account of another ACC Entity (or ACC Entities), as applicable.
Notwithstanding the foregoing, this provision shall not be construed in a manner which conflicts
with ACC’s requirement to obtain or maintain a certain level of margin with respect to any
Transaction.

C. All Collateral legally held by any ACC Entity (either directly or through an agent) shall
be held both for itself and for the benefit of all ACC Entities and the ACC Group.

Section 3. Periodic Netting and Setoff.

A. Each of the parties hereto acknowledges that (i) the parties have or may have entered into
the Transactions; and (ii) all Transactions have been and will be entered into, among other things,
in consideration of each other.

B. Effective as of the date of this Agreement, each ACC Entity shall have the right, from
time-to-time in its sole business discretion and without prior notice, to aggregate, setoff and net
any payment obligations arising under the Transactions. The parties specifically agree that
netting in respect of two or more Transactions may occur upon the election of any ACC Entity. This
periodic netting process shall be handled as set forth within this Section 3 for all Collateral
subject to Transactions. Accordingly,

	 	(1)	 	If any Luminent Entity owes (or has contingent obligations to)
any ACC Entity pursuant to any of the Transactions, any ACC Entity may, without
prior notice, aggregate, setoff and net: (a) any Collateral pledged by any
Luminent Entity to any ACC Entity; (b) any Collateral required to be paid or
returned by any ACC Entity to any Luminent Entity; and (c) any payment due any
Luminent Entity from any ACC Entity. Specifically, a member of the ACC Group
may net (a) amounts owed to any Luminent Entity by any ACC Entity under the
Transactions; and (b) amounts owed by any Luminent Entity to the other members
of the ACC Group under the Transactions to satisfy any Obligations of any
Luminent Entity to any ACC Entity.

	 	(2)	 	If amounts owed by all parties are equal, no party shall make a
payment under this Section 3.

	 	(3)	 	All payments due pursuant to this Section 3 shall be made on
the payment date, which shall be no later than the first business day after the
netting. All payments shall be made by wire transfer.

	 	(4)	 	Upon making such net payment and/or delivery, and provided that
the Collateral subject to such Transactions has been returned (if required)
properly to the appropriate party respectively and that all other obligations
of the parties hereto have been satisfied, each of the parties agrees to
reflect on its books and records that such netted Transactions have been
discharged fully.

	 	(5)	 	Any ACC Entity may, upon prior notice to the applicable
Luminent Entity, sell at private or public sale any Collateral and apply the
proceeds thereof against any Obligations, or retain and apply any Collateral in
satisfaction of any such Obligations to any ACC Entity;

	 	(6)	 	Any ACC Entity may setoff any obligations of any ACC Entity to
any Luminent Entity against any Obligations of any Luminent Entity to another
member of the ACC Group; and

	 	(7)	 	The ACC Group may collect from Luminent Group any losses, costs
or expenses incurred by any ACC Entity in taking any of the above-mentioned
actions (including commissions and reasonable legal fees and expenses), all of
which will be secured by the Collateral.

C. In the event that the Obligations to be netted are not fixed, the ACC Group may net and
setoff amounts pursuant to this Section 3 believed in good faith not to exceed 100% of the
Obligations due from the Luminent Entity and including contractual and/or statutory interest, costs
and anticipated attorney’s fees.

D. Any netting ACC Entity shall have the right to net and/or setoff Obligations and
Transactions in any order it chooses.

Section 4. Default Netting and Setoff.

A. An “Event of Default” shall have the respective meaning assigned to such terms in
the relevant Transaction Documents.

B. In addition to all other rights and remedies available under the relevant Transaction
Documents, an Event of Default shall give each ACC Entity the netting and setoff rights specified
in Section 3.

Section 5. Close-Out Netting and Setoff.

A. Upon termination of this Agreement, without limiting any other provision of this Agreement
or any Transaction Document, any member of the ACC Group may aggregate, setoff and net against any
Obligations of any Luminent Entity any Collateral, or the value thereof, pledged by or required to
be delivered or paid by any Luminent Entity to any member of the ACC Group in connection with such
terminated Transactions. In addition, upon termination under this Section, any member of the ACC
Group may aggregate, setoff and net against any Obligations of any Luminent Entity any Collateral,
or the value thereof, pledged by or required to be delivered or paid by any member of the ACC Group
to any Luminent Entity in connection with such terminated Transactions. Thereupon, the only
delivery obligation of any of the parties in connection with such Transactions will be for the
parties to deliver such Collateral or a net cash payment, as the case may be, as may be required
after giving effect to such aggregation, netting and setoff.

B. The method by which the parties hereto will value such Collateral for such netting and
setoff purposes will be determined by the method prescribed in the applicable agreement or, in the
absence of a prescribed method, by the ACC Entities in a commercially reasonable manner.

C. In the alternative, the ACC Group may net and setoff amounts pursuant to this Section in
accordance with the netting and setoff rights specified in Section 3.

D. Each ACC Entity shall aggregate any gains, losses and costs with respect to all
transactions into a single net amount (the “Settlement Amount”). It is expressly agreed
that the ACC Entities shall not be required to enter into replacement transactions in order to
determine the Settlement Amount. The ACC Group and the Luminent Group will provide one another
with a statement showing, in reasonable detail, their calculations of gains, losses and costs,
including all relevant quotations and specifying any amount payable, and giving details of the
relevant account to which any amount payable is to be paid.

Section 6. Remedies.

A. None of the rights and remedies of each member of the ACC Group shall be exclusive of any
other available right or remedy, and each remedy shall be cumulative and in addition to any other
right or remedy of each member of the ACC Group. Each member of the ACC Group shall be entitled to
exercise its rights and remedies against the Luminent Group in such order and to such extent as it,
in its sole discretion, deems appropriate. It is understood that a prior demand or call, or prior
notice of the time and place of such sale or purchase, shall not be considered a waiver of the
right of any member of the ACC Group to sell the Collateral without demand or notice. Luminent
Mortgage Capital, Inc., acknowledges that all of the Collateral (other than cash) is of a type that
may decline rapidly in value and/or is customarily sold on or in a recognized market (including the
whole loan market), and therefore, the Luminent Group is not entitled to prior notification of any
intended sale or other disposition thereof. The Luminent Group shall remain liable for any and all
Obligations it owes to any member of the ACC Group remaining unpaid or unsatisfied after the
application of the Collateral and the exercise of all rights hereunder.

B. All Obligations shall bear interest equal in value to the relevant rate specified in the
applicable Transaction Documents or, if no rate is specified, in respect of each day, the overnight
Federal Funds (Effective) Rate for such day that is quoted the next business day on Reuters Screen
FEDFUNDS1 under the heading under the caption “EFFECT” for such day, or, if that rate is
unavailable, the weighted average of the rates on overnight Federal funds transactions with members
of the Federal Reserve System arranged by Federal funds brokers on such day as published by the
Federal Reserve Bank of New York on the next business day.

C. The rights and remedies granted hereby to the ACC Group are in addition to any rights and
remedies, and supercede any limitations on such rights and remedies that are inconsistent herewith,
that they may have under any existing or future agreements with any Luminent Entity unless, in the
case of any future agreements, any inconsistent provision therein is stated explicitly to supercede
this Agreement. Without limiting the generality of the foregoing, nothing herein shall be
construed as a requirement that a member of the ACC Group cause Collateral held on account of a
particular Transaction to be attributed (in whole or in part) to any other Transaction in
determining whether that member of the ACC Group is entitled to make a demand or call upon the
Luminent Entity for additional securities, monies or other property under any such other
Transaction.

Section 7. Multiple Party Setoff.

A. ACC, along with its Affiliates, and Luminent Mortgage Capital, Inc., along with its
Affiliates, agree to engage in a triangular or multi-party setoff pursuant to this Agreement if
necessary. Each member of the ACC Group and the Luminent Group agrees that, at the option of any
party to this Agreement, and without prior notice to any other party, any and all amounts payable
pursuant to Section 3, Section 4 or Section 5 to any party may be reduced or satisfied by a setoff
against any other amounts payable by or to any other party to this Agreement. For purposes of this
Agreement, the parties agree that (i) all of the ACC Entities constitute a single unit for purposes
of setoff and (ii) all of the ACC Entities constitute a single unit for purposes of setoff.

B. This right of setoff, recognized in New York law and the United States Bankruptcy Code,
shall be held by all parties to this Agreement. If any amounts are so set off, these amounts are
to be discharged promptly and in all respects.

Section 8. Recoupment.

The rights of the ACC Group contained herein are in addition to any and all recoupment rights
that the ACC Group may have at law or in equity against the Luminent Group.

Section 9. Choice of Law; Waiver of Jury Trial.

THIS AGREEMENT AND EACH AND EVERY OTHER TRANSACTION DOCUMENT AND TRANSACTION BETWEEN THE
PARTIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW
YORK WITHOUT REGARD TO THE CONFLICT OF LAWS PROVISIONS THEREOF (OTHER THAN NEW YORK
GENERAL OBLIGATIONS LAW SECTION 5-1401), AND IN THE EVENT THAT ANY LAWSUIT IS COMMENCED RELATING TO
