EMPLOYMENT AGREEMENT

     This Employment Agreement (the “Agreement”) is made and entered into as of August 15, 2006
(the Effective Date”) between ODYSSEY RE HOLDINGS CORP. (“Employer”), a holding company,
incorporated in the State of Delaware, that owns all of the shares of the entities comprising the
group of reinsurance and insurance companies constituted by Odyssey America Reinsurance Corporation
and its subsidiaries, and Mr. Richard Scott Donovan (“Executive”), an individual residing at 702
Thomas Court; Southlake, TX 76092.

     WHEREAS, the Board of Directors of Employer (the “Board”) believes it is in the best interests
of Employer (i) to ensure that the reasonable employment, compensation and benefits expectations of
Executive are satisfied; (ii) to induce and encourage Executive to join Employer as a senior
executive; and (iii) to reward Executive’s commitment to provide continued service, full attention
and dedication to Employer, by providing Executive with the compensation and. benefits arrangements
described below during the term provided for in this Agreement; and

     WHEREAS, to accomplish these objectives, the Board has authorized and directed Employer to
enter into this Agreement with Executive.

     NOW THEREFORE, IT IS AGREED AS FOLLOWS:

 

 

ARTICLE I

EMPLOYMENT AND DUTIES; COMPENSATION

Section 1: Duties.

     During the term of this Agreement, Executive shall be employed by and shall serve Employer
in the capacity of Executive Vice President and Chief Financial Officer, and shall be employed
by and/or shall serve such subsidiaries of Employer in such capacities as Employer shall from
time to time designate and as are consistent with Executive’s position as Executive Vice
President and Chief Financial Officer of Employer. Executive shall devote substantially all of
his business time to the business and affairs of Employer and shall use his best efforts,
skills, and energy to promote Employer’s interests, provided that it shall not be a violation
of the foregoing for Executive to act or serve as a director, trustee or committee member of
any civic or charitable organization, as long as such activities are disclosed to Employer and
Employer, in the exercise of its reasonable judgment, agrees that such activities do not
present any conflict of interest with the Employer.

Section 2: Term of Employment.

     The term of employment of Executive by Employer shall commence as of August 15, 2006 (the
“Commencement Date”) and shall continue until August 15, 2009 (the “Term”). At any time prior to
the expiration of the Term, Employer and Executive may,

2

 

by mutual written agreement, extend Executive’s employment under the terms of this Agreement
for such additional periods as they may agree.

Section 3: Salary, Benefits and Additional Compensation

     As compensation and consideration for the performance by Executive of his duties and
responsibilities pursuant to this Agreement, Employer agrees to pay, and/or to cause one or more of
its subsidiaries to pay Executive, and Executive agrees to accept the following amounts and
benefits (all Dollar amounts referred to herein are in United States Dollars):

(a) Base Salary:

     During the term hereof, Executive shall receive an annual base salary of Five Hundred Thousand
Dollars ($500,000), as it may be increased from time to time at the discretion of the Employer’s
Board of Directors (“Base Salary”), pro rated for any calendar year within the Term for which
employment does not extend for the entire calendar year. The Base Salary shall be paid to Executive
in equal bi-weekly installments.

(b)  Bonus Pool:

     Executive shall participate in the bonus pool (the “Bonus Pool”) created with respect to each
accident underwriting year, consisting of that portion of the underwriting profit for such year
designated by the Board, and the Board shall establish performance criteria upon which Executive’s
bonus shall be determined. During Executive’s employment under this Agreement, he shall be
eligible to receive a target bonus of 100%

3

 

of his base salary; actual bonus awards may exceed, match or be less than the target bonus as
Executive’s performance or Employer’s performance warrant. The form of payment and other terms and
conditions of such bonus shall be determined by the Board. Notwithstanding the foregoing, to the
extent Executive is a “covered employee” within the meaning of Section 162(m) of the Internal
Revenue Code of 1986, as amended (the “Code”), the annual bonus may be implemented and
administered in a manner intended to insure the treatment of such bonus as “performance-based
compensation” within the meaning of Section 162(m) of the Code (including, without limitation, by
having the relevant performance goals established by the Compensation Committee of the Board of
Directors of Employer and having the Compensation Committee certify the achievement of such goals
before the annual bonus is paid).

     Bonuses will be paid on or about March 15 of the year following the related accident
underwriting year (and in no event later than April 15 of the year following the related accident
underwriting year). For the year ended December 31, 2006, Executive shall receive a guaranteed
minimum bonus of $500,000, of which no less than $350,000 shall be paid in cash, with the remainder
being comprised of that number of shares of Employer’s Common Stock, par value $.01 per share
(“Restricted Shares”), which, when multiplied by the closing price of such common stock on the New
York Stock Exchange on the date of such grant (the “Grant Date”), yields an aggregate sum such that
when added to the amount of Executive’s cash payment hereunder shall equal no less than $500,000.
Except as otherwise provided in this Agreement, the foregoing grant shall be subject to the terms
of Employer’s Restricted Share Plan. Executive shall become vested in the shares granted pursuant
to the foregoing sentence, and all restrictions shall lapse,

4

 

on the first anniversary of the Grant Date with respect to one third (33.3%) of the Restricted
Shares and on each anniversary thereafter with respect to an additional one third (33.3%) of the
Restricted Shares, such that on the third anniversary of the Grant Date, all restriction on the
Restricted Shares shall lapse.

(c)  Restricted Stock Grant:

     (i) Executive shall receive as of the date hereof an award of that number of Restricted Shares
of Employer, consisting of its Common Stock, par value $.01 per share, which when multiplied by the
simple average of the closing prices of such common stock on the New York Stock Exchange on the
twenty (20) business days next preceding the date of execution hereof, yields the aggregate sum of
One Million Dollars ($1,000,000), and, subject to subparagraph (ii) below, the foregoing grant (the
“Incentive Bonus”) shall be subject to the terms of Employer’s Restricted Share Plan. Executive
shall become vested in the shares granted pursuant to the foregoing sentence, and all restrictions
shall lapse, on August 15, 2007 with respect to twenty percent (20%) of the Restricted Shares and on
each anniversary thereafter with respect to an additional twenty percent (20%) of the Restricted
Shares such that on August 15, 2011 all restrictions on the Restricted Shares constituting the
Incentive Bonus shall lapse.

     (ii) A copy of the award document relating to the Incentive Bonus (“Award Document”)
is attached hereto as Exhibit A. The Award Document provides that (a) upon Executive’s
Termination of Employment as a result of death, disability, reaching retirement age, Change in
Control (as defined in Article II, Section 7 below), termination by Executive as a result of a
Constructive Termination (as defined in Article II, Section 4 below), or termination by Employer
for reasons other than For Cause (as defined in

5

 

Article II, Section 3 below) the restricted period applicable to any Restricted Shares granted to
Executive thereunder shall terminate and Executive shall become fully vested in such Award; and
(b) if the stock of Employer at any time during the restricted period ceases to be publicly
traded, then Executive shall have the option to receive a cash payment, payable by Employer within
ten (10) days following written notice from Executive no later than thirty (30) days following the
delisting of Employer stock from the exchange, equal to the number of shares of Restricted Stock
of Employer granted under the Award Document and held by Executive as of the delisting of the
stock times the greater of (i) the share price of Employer stock as of the close of business
forty-five (45) trading days prior to its delisting and (ii) the average share price of Employer
stock (based on end of business day values) over the forty-five (45) trading day period prior to
delisting. The foregoing subparagraph (b) shall not apply if the stock of Employer ceases to be
publicly traded as a result of Employer having made a general assignment for the benefit of
creditors, been adjudicated as bankrupt or insolvent, or having filed a voluntary petition in
bankruptcy, a petition or answer seeking an arrangement with creditors or to take advantage of any
insolvency law or having filed an answer admitting the material allegations of a petition filed
against Employer in bankruptcy.

     (iii) Employer will take whatever action necessary, including, without limitation,
amendment of the Odyssey Re Holdings Corp. Restricted Share Plan, to ensure that the issuance
of Restricted Shares by Employer to Executive pursuant to the Award Documents does not exceed
the maximum number of shares available for such purpose.

6

 

(d)  Living Allowance:

     (i) During the term of this Agreement, for such time as Executive’s principal residence is in
the State of Texas, Executive shall be entitled to a bi-weekly living allowance (“Living
Allowance”) of $3,000. Each bi-weekly payment of the Living Allowance shall be “grossed up” such
that after all federal, state, local and other withholdings and similar taxes and payments required
by applicable law have been deducted, Executive will receive the amount stated in the previous
sentence. This Section 3(d)(i) shall no longer apply upon Executive’s relocation as described in
Section 3(d)(ii) below.

     (ii) In the event that Executive relocates his principal residence to the New York
Metropolitan Area, promptly upon presentation of appropriate substantiation, the Employer shall
pay, or reimburse Executive for, the following relocation expenses: (a) packing, moving, storage
and travel expenses reasonably incurred by Executive in connection with moving Executive,
Executive’s immediate family, and their possessions; (b) home sale and purchase closing costs,
including loan origination fees, brokers’ fees and commissions, home appraisal and inspection fees,
title costs, attorney and escrow office fees, recording fees, and state and local recording,
transfer and real property gains taxes, etc., reasonably incurred by Executive in connection with
Executive and his family moving from their residence; and (c) such other expenses reasonably
related to Executive’s move.

     During the term of this Agreement, Executive shall be entitled to the following fringe

     Subject to Section 8 of this Article II, Employer shall provide Executive with the following
payments and benefits upon termination of employment:

Section 1: Termination Due to Death.

     The employment of Executive under this Agreement shall terminate upon Executive’s death. In
the event of Executive’s death during Executive’s employment hereunder, the estate or other legal
representative of Executive shall be entitled to receive the following:

9

 

(a)  Base Salary:

     Employer shall pay to Executive’s estate or other legal representative of Executive, his Base
Salary and Living Allowance for the period ending one year following the month in which Executive
dies. Such an amount and all other amounts payable under this Section 1 of Article II shall be paid

paid.

(b)  Payment from Bonus Pool:

     Employer shall pay to the estate or other legal representative of Executive, (i) all amounts
accrued in the Bonus Pool by Executive with respect to years preceding the year in which the death
of Executive occurs and (ii) the pro-rated bonus payable with respect to the year in which the
death of Executive occurs.

(c)  Restricted Stock:

     Upon the death of Executive, the restricted period with respect to all Restricted Stock
previously awarded to Executive including, without limitation, Restricted Stock of Employer
awarded pursuant to this Agreement, shall terminate and the Executive’s estate or other legal
representative shall become fully vested in all Restricted Stock previously awarded to Executive.
In addition, upon the death of Executive, all other equity awards shall vest (and, with respect to
stock options and stock appreciation rights, if any, shall become fully exercisable).

10

 

Section 2: Termination by Reason of Disability.

     If, during the term of this Agreement, Executive, in the judgment of the Board, has failed to
perform his duties under this Agreement on account of illness or physical or mental incapacity, and
such illness or incapacity continues for a period of more than (i) six (6) consecutive months or
(ii) one hundred eighty three (183) days in any consecutive three hundred sixty-five (365) day
period, Employer shall have the right to commence process to terminate Executive’s employment under
this Agreement on account of disability. Employer shall send written notice to Executive of (x) its
intention to commence such process, (y) a medical doctor chosen by Employer to make the
determination referred to in the next sentence, and (z) Executive’s right within ten (10) days of
receipt of the notice to choose a second medical doctor to make such determination. The purpose of
the process shall be to determine whether Executive is unable on account of illness or physical or
mental incapacity to perform his duties under this Agreement. Executive shall fully cooperate in
this process, including by making himself available for and consenting to all examinations and
tests required by any doctor making the aforesaid determination. The aforesaid determination shall
be made by the medical doctor chosen by Executive, if he exercises his foregoing right to choose a
doctor, and the medical doctor chosen by Employer. If the determination is being made by two
medical doctors and they cannot agree within fifteen (15) days of their both being chosen, they
shall as soon as reasonably possible select a third medical doctor to make the determination, who
shall make the determination within fifteen (15) days of being chosen. The determination made by
the foregoing process shall be conclusive. In the

11

 

event the Executive’s employment is terminated on account of disability, Executive’s rights to
compensation and benefits shall be as follows:

(a)  Base Salary:

     Executive shall be paid his pro rated Base Salary, as determined in accordance with the terms
of Section 3(a) of Article I for a period of no less than one year, less any benefits paid to him
under disability insurance policies maintained by Employer, until his termination on account of
disability.

(b)  Payment from Bonus Pool:

     Employer shall pay to Executive, when the same would ordinarily be paid, (i) all amounts
accrued in the Bonus Pool by Executive with respect to years preceding the year in which
termination due to disability of Executive occurs and (ii) the pro-rated bonus payable with respect
to the year in which termination due to the disability of Executive occurs.

(c)  Restricted Stock:

     The restricted period with respect to all restricted stock previously awarded to Executive
shall terminate and Executive shall become fully vested in all Restricted Stock previously awarded
to Executive, including, without limitation, Restricted Stock awarded pursuant to this Agreement.
In addition, all other equity awards shall vest (and, with respect to stock options and stock
appreciation rights, if any, shall become fully exercisable).

12

 

(d)  Living Allowance:

     Executive shall be paid his pro rated Living Allowance, as determined in accordance with the
terms of Section 3(d) of Article I, until his termination on account of disability.

Section 3: Termination for Cause.

     “Termination for Cause” shall mean termination by Employer of Executive’s
employment by Employer by reason of:

     (i) a willful failure by Executive in bad faith to substantially perform his
duties with Employer resulting in material harm to Employer; or

     (ii) Executive’s conviction of a felony involving moral turpitude.

Executive must be given written notice that Employer intends to terminate his employment for
Cause. Such written notice shall specify the particular act or failure to act constituting the
basis of the intention to so terminate employment. In the case of a Termination for Cause under
clause (i) above, Executive shall be given the opportunity, within twenty (20) days of the
receipt of such notice, to meet with the Board of Directors of Employer (the “Board of
Directors”) to refute or explain such act or failure to act. If such act or failure to act is
reasonably determined by the Board of Directors to be in violation of Clause (i), Executive shall
be given ten (10) days after such meeting to correct such act or failure to act, and upon failure
of Executive within such ten (10) day period to correct such act or failure to act to the
reasonable satisfaction of the Board

13

 

of Directors, Executive’s employment by Employer shall be terminated. In the case of Termination
for Cause under (ii) above, Executive’s employment shall be terminated as of the date such notice
is given.

     In the event the Board shall terminate Executive’s employment for Cause, Executive shall be
entitled only to the following:

(a)  Base Salary and Living Allowance:

     Within thirty (30) days of the date of Executive’s Termination for Cause, Executive shall be
paid his pro rated Base Salary, as determined in accordance with the terms of Section 3(a) of
Article I, and his Living Allowance, as determined in accordance with the terms of Section 3(d),
through the date of termination of employment.

(b)  Payment from Bonus Pool:

     Executive shall forfeit all rights to payments from the Bonus Pool.

Section 4: Constructive Termination and Termination by Employer other than for Cause.

     Notwithstanding anything in this Agreement to the contrary, Executive’s employment
hereunder may be terminated by Employer without Cause and Executive may terminate his
employment hereunder in the case of a Constructive Termination as defined in this section,
provided however, that in the event that Executive’s employment is terminated in accordance
with the terms of this Section 4, Executive shall be entitled to receive:

14

 

(a)  Base Salary and Living Allowance:

     Within thirty (30) days of his termination of employment, Employer shall pay to Executive a
lump sum payment equal to:

     (i) his Base Salary, as determined in accordance with the terms of Section 3(a) of Article I,
for the month in which termination occurs, and for the period incepting the first day of the month
immediately following the month in which termination occurs to the end of the Term, or any
extension thereto, inclusive (but in no event for less than one (1) year); and

     (ii) his Living Allowance, as determined in accordance with the terms of Section 3(d) of
Article I, through the date of termination of employment (or, if longer, the end of the lease term
for his temporary living quarters in the New York Metropolitan area; provided, however, that
Executive shall use reasonable efforts to sublease the premises or assign the lease agreement, and
in such event the Living Allowance shall not be paid to the extent Executive’s obligations under
the lease are relieved).

(b)  Payment from Bonus Pool:

     Employer shall pay to Executive, within thirty (30) days following termination of employment,
(i) all amounts accrued in the Bonus Pool by Executive with respect to years preceding the year in
which termination of employment of Executive occurs and (ii) the pro-rated bonus payable with
respect to the year in which termination of employment of Executive occurs, determined for these
purposes only by taking the average of the bonuses actually paid to Executive for the three
calendar years preceding

15

 

the year in which termination of employment of Executive occurs (or, if shorter, the shorter
of the number of years Executive is employed by Employer or the number of years in which he
participated in the Employer’s bonus pool).

(c)  Restricted Stock:

     (i) The restricted period applicable to all Restricted Stock previously awarded to Executive
shall terminate and the Executive shall become fully vested in all Restricted Stock previously
awarded to Executive, including, without limitation, Restricted Stock awarded pursuant to this
Agreement. Executive shall, upon such termination, have the option to take cash in lieu of
Restricted Stock with respect to all, or any portion, of the shares of Restricted Stock that vest
as a result of this subparagraph based on a share price for such stock which is the greater of (a)
the share price of Employer as of the close of business on the business day next preceding the date
of termination of employment and (b) the share price ten (10) business days prior to the date
determined under paragraph (a) above (or the closing price of the next preceding business day, if
such date does not fall on a business day). In addition, all other equity awards shall vest (and,
with respect to stock options and stock appreciation rights, if any, shall become fully
exercisable).

     (ii) Executive shall give Employer written notice within ten (10) business days following
termination of employment under this Section 4 specifying the number of shares of Restricted Stock
with respect to which Executive has elected to take cash in lieu of shares of Restricted Stock.
Employer shall within thirty (30) days of receipt of such notice deliver to Executive a check in
payment of the value of the shares of Restricted Stock as determined in the immediately preceding
sentence and share certificates

16

 

evidencing the remaining shares of Restricted Stock that have vested as a result of termination of
employment under this Section 4 and with respect to which Executive has not exercised his election
to take cash in lieu of shares.

(d)  Health Coverage.

     Executive’s medical and dental coverage shall cease upon the termination of the Executive’s
employment. In the event of such termination in accordance with the terms of this Section 4,
Employer shall provide Executive with notice and enrollment materials confirming Executive’s right
to continue medical and dental insurance coverage to the extent permitted under COBRA; provided
however, that Executive shall only be required to pay the premiums charged to similarly-situated
active employees during the entire COBRA continuation period, and the Employer shall pay the
remaining cost of coverage.

     For purposes of this Agreement, “Constructive Termination” shall mean the termination of
employment by Executive following written notice to Employer for any of the following reasons:

     (i) without Executive’s express written consent, the loss of Executive’s position
described in Article I, Section 1 or a material alteration in Executive’s position or
responsibility as so described;

     (ii) without Executive’s express written consent, a breach by Employer of any of its
material obligations set forth in this Agreement;

17

 

     (iii) any failure by a successor to Employer to assume Employer’s obligations under this
Agreement, either expressly or by operation of law, or, if Employer sells all or substantially all
of its assets, or as a result of a sale by Employer’s majority stockholder, Fairfax of all of
Employer or a controlling interest in Employer and in either case, as a result thereof, any
failure by the purchaser to assume Employer’s obligations under this Agreement; or

     (iv) without Executive’s express written consent, relocation of Executive’s work situs to a
location that is not in the New York Metropolitan area.

     Executive must give written notice to Employer if he intends to terminate his employment
because of the occurrence of one of the circumstances constituting Constructive Termination under
this Section 4. Such written notice shall specify the particular act or failure to act constituting
the basis of Executive’s claim that Constructive Termination has occurred. Employer shall be given
the opportunity, within twenty (20) days of the receipt of such notice, to fully cure any such act
or failure to act.

     Notwithstanding any provision of this Agreement to the contrary, if, at the time of
Executive’s termination of employment with the Employer, he is a “specified employee” as defined
in Section 409A of the Code, and one or more of the payments or benefits received or to be
received by Executive pursuant to this Agreement would constitute deferred compensation subject to
Section 409A, no such payment or benefit will be provided under this Agreement until the earliest
of (A) the date which is six (6) months after his “separation from service” for any reason, other
than death or “disability” (as such terms are used in Section 409A(a)(2) of the Code), (B) the
date of his death or

18

 

“disability” (as such term is used in Section 409A(a)(2)(C) of the Code) or (C) the effective
date of a “change in the ownership or effective control” of the Employer (as such term is used in
Section 409A(a)(2)(A)(v) of the Code). If any payment is delayed pursuant to the above sentence,
the first payment after such delay expires shall include all amounts not previously paid as a
result of such delay. The determination of whether Section 409A of the Code requires any such
delay shall be made by Employer, after consultation with Executive’s tax counsel. The provisions
of this paragraph shall only apply to the extent required to avoid Executive’s incurrence of any
penalty tax or interest under Section 409A of the Code or any regulations or Treasury guidance
promulgated thereunder. In addition, if any provision of this Agreement would cause Executive to
incur any penalty tax or interest under Section 409A of the Code or any regulations or Treasury
guidance promulgated thereunder, the Employer shall reform such provision to maintain to the
maximum extent practicable the original intent of the applicable provision without violating the
provisions of Section 409A of the Code.

Section 5: Non-Extension of Employment.

Employer shall provide Executive written notice (“Notice”) of its intention not to extend
Executive’s employment under the terms of this Agreement (“Non-Extension of Employment”) at least
ninety (90) days prior to the end of the Term, and in such event, Executive’s employment with
Employer shall terminate upon the completion of the final day of the Term. In the event of
Non-Extension of Employment in accordance with the terms of this Section 5, Executive shall be
entitled to receive:

19

 

(a)  Base Salary; Health Coverage:

Employer shall continue to pay Executive the Base Salary (at the rate in effect at the end of the
Term) for twelve (12) months following his termination of employment at such intervals as the same
would have been paid to Executive had he remained in the active service of Employer. Executive’s
medical and dental coverage shall cease upon the termination of the Executive’s employment. In the
event of such termination in accordance with the terms of this Section 5, Employer shall provide
Executive with notice and enrollment materials confirming Executive’s right to continue medical and
dental insurance coverage to the extent permitted under COBRA; provided however, that Executive
shall only be required to pay the premiums charged to similarly-situated active employees during
the entire COBRA continuation period, and Employer shall pay the remainder of the cost of coverage.

(b)  Payment from Bonus Pool:

Employer shall pay to Executive, thirty (30) days following the end of the Term, (i) all
amounts accrued in the Bonus Pool by Executive with respect to years preceding the year in
which Non-Extension of Employment occurs and (ii) the pro-rated bonus payable with respect to
the year in which Non-Extension of Employment occurs, determined for these purposes only by
taking the average of the bonuses actually paid to Executive for the three calendar years
preceding the year in which Non-Extension of Employment occurs (or, if shorter, the shorter of
the number of years Executive is employed by Employer or the number of years in which he
participated in the Employer’s bonus pool).

20

 

(c)  Restricted Stock:

     (i) The restricted period applicable to all Restricted Stock previously awarded to
Executive shall terminate and the Executive shall become fully vested in all Restricted Stock
previously awarded to Executive, including, without limitation, Restricted Stock awarded
pursuant to this Agreement. Executive shall, upon such termination, have the option to take
cash in lieu of Restricted Stock with respect to all, or any portion, of the shares of
Restricted Stock that vest as a result of this subparagraph based on a share price for such
stock which is the greater of (a) the share price of Employer as of the close of business on
the business day next preceding the date of termination of employment and (b) the share price
ten (10) business days prior to the date determined under paragraph (a) above (or the closing
price of the next preceding business day, if such date does not fall on a business day). In
addition, all other equity awards shall vest (and, with respect to stock options and stock
appreciation rights, shall become fully exercisable).

     (ii) Executive shall give Employer written notice within ten (10) business days following
termination of employment under this Section 5 specifying the number of shares of Restricted Stock
with respect to which Executive has elected to take cash in lieu of shares of Restricted Stock.
Employer shall within thirty (30) days of receipt of such notice deliver to Executive a check in
payment of the value of the shares of Restricted Stock as determined in the immediately preceding
sentence and share certificates evidencing the remaining shares of Restricted Stock that have
vested as a result of

21

 

termination of employment under this Section 5 and with respect to which Executive has not
exercised his election to take cash in lieu of shares.

     For the avoidance of doubt, this Section 5 shall not apply to the extent Section 4 above is
applicable.

Section 6: Voluntary Termination.

     Executive may terminate his employment under this Agreement voluntarily by giving no less
than sixty (60) days written notice to Employer of his intention to voluntarily terminate his
employment with Employer. “Voluntary Termination” shall mean termination by Executive of
Executive’s employment by Employer other than (i) Constructive Termination as described in Section 4, (ii) “Termination Upon a Change in Control,” as described in Section 6, or (iii) termination by
reason of Executive’s death or disability as described in Sections 1 and 2.

     In the event that Executive’s employment is voluntarily terminated by Executive, Executive’s
rights to compensation and benefits shall be identical to those to which he would be entitled had
he been Terminated for Cause, except that Employer shall pay to Executive, when the same would
ordinarily be paid, (i) all amounts accrued in the Bonus Pool by Executive with respect to years
preceding the year in which the Voluntary Termination of Executive occurs and (ii) the prorated
bonus payable with respect to the year in which termination of Executive occurs.

22

 

Section 7: Termination Upon a Change of Control.

     “Termination Upon a Change in Control” shall mean the termination of Executive’s employment
by Employer or the successor company (otherwise than for Cause as provided in Section 3 of this
Article) or by Executive in a Constructive Termination, in either case within one year following
a Change in Control.

     In the event that Executive’s employment is Terminated Upon a Change in Control, Executive’s
rights to compensation, Restricted Stock and benefits shall be identical to those to which he
would be entitled had he been terminated by Employer other than for Cause pursuant to Section 4,
provided, however, that the minimum severance benefit described in Section 4(a)(i) (relating to

Fairfax, acquired direct or indirect beneficial ownership (within the meaning of Rule 13d-3 under

standard waiver and release.

ARTICLE III

MISCELLANEOUS PROVISIONS

Section 1: Payment Obligations. The obligation of Employer to pay Executive the
compensation and to make the arrangements provided herein shall be unconditional, and Executive
shall have no obligation whatsoever to mitigate damages hereunder. If litigation after a Change in
Control (otherwise than in connection with a Termination for Cause which is ultimately upheld in
litigation) shall be brought to enforce or interpret any provision contained herein, Employer, to
the extent permitted by applicable law, hereby indemnifies Executive for Executive’s reasonable
attorney’s fees and disbursements incurred in such litigation.

Section 2: Confidentiality. Executive agrees that all confidential and proprietary
information relating to the business of Employer shall be kept and treated as

25

 

confidential both during and after the term of this Agreement, except as may be permitted in
writing by the Board or as such information is within the public domain or comes within the
public domain without any breach of this Agreement.

Section 3: Withholdings. Unless otherwise provided herein, all compensation and
benefits to Executive hereunder shall be reduced by all federal, state, local and other
withholdings and similar taxes and payments required by applicable law.

Section 4: Parachute Payments.

(a) Subject to Article III, Section 4(b) below, notwithstanding anything in this Agreement to the
contrary, the amount of any payment or benefit to be received by Executive pursuant to this
Agreement or otherwise which would be subject to the excise tax imposed by Section 4999 of the Code
shall be reduced (but not below zero) by the amount, if any, necessary to prevent any part of any
such payment or benefit received or to be received by Executive (such foregoing payments or
benefits referred to collectively as the “Total Payments”), from being subject to such excise tax,
but only if and to the extent such reduction will also result in, after taking into account all
applicable state and Federal taxes (computed at the highest applicable marginal rate), including
any taxes payable pursuant to Section 4999 of the Code, a greater after-tax benefit to Executive
than the after-tax benefit to Executive of the Total Payments computed without regard to any such
reduction. For purposes of the foregoing, (a) no portion of the Total Payments shall be taken into
account which in the opinion of tax counsel selected by Executive (“Tax Counsel”) does not
constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code; (b) any
reduction in payments or benefits pursuant to this

26

 

Agreement shall be computed by taking into account, in accordance with Section 280G(b)(4) of the
Code, that portion of the Total Payments which is reasonable compensation, within the meaning of
Section 280G(b)(4) of the Code, in the opinion of Tax Counsel; (c) the value of any non-cash
benefits or of any deferred or accelerated payments or benefits included in the Total Payments
shall be determined by a public accounting firm, selected by Executive, in accordance with the
principles of Section 280G(d)(3) and (4) of the Code and the Treasury Regulations there; and (d) in
the event of any uncertainty as to whether a reduction in Total Payments to Executive is required
pursuant hereto, the Employer shall initially make all payments otherwise required to be paid to
Executive hereunder, and any amounts so paid which are ultimately determined not to have been
payable hereunder (other than as a loan to Executive), either (x) upon mutual agreement of
Executive and Employer, or (y) upon Tax Counsel furnishing Executive with its written opinion
setting forth the amount of such payments not to have been so payable (other than as a loan to
Executive under this Section 4(a)), or (z) in the event a portion of the Total Payments shall be
determined by a court or an Internal Revenue Service proceeding to have otherwise been an “excess
parachute payment,” to the extent permitted by law, the amount so determined in (x), (y) or (z)
shall constitute a loan by Employer to Executive under this Section 6.2, and Executive shall repay
to Employer, within ten (10) business days after the time of such mutual agreement, such opinion is
so furnished to Executive, or of such determination, as applicable, the amount of such loan plus
interest thereon at the rate provided in Section 1274(b)(2)(B) of the Code for the period from the
date of the initial payments to Executive to the date of such

27

 

repayment by Executive. All fees and expenses of any Tax Counsel or accounting firm selected under
this Section 4(a) shall be borne solely by Employer.

(b) Notwithstanding Article III, Section 4(a) above, and notwithstanding anything else in this
Agreement to the contrary, in the event the Total Payments exceed 110% of 2.99 multiplied by
Executive’s “base amount” (as defined in Section 280G(b)(3)(A) of the Code), then, in addition to
any other benefits provided under or pursuant to this Agreement or otherwise, the Employer shall
pay to the Executive at the time any such payments are made under or pursuant to this Agreement or
any other agreements, an amount equal to the amount of any excise tax imposed or to be imposed on
the Executive pursuant to Section 4999 of the Code (the amount of any such payment, the “Parachute
Tax Reimbursement”). In addition, the Employer shall “gross up” such Parachute Tax Reimbursement
by paying to Executive at the same time an additional amount equal to the aggregate amount of any
additional taxes (whether income taxes, excise taxes, special taxes, employment taxes or otherwise)
that are or will be payable by Executive as a result of the Parachute Tax Reimbursement being paid
or payable to Executive and/or as a result of the additional amounts paid or payable to Executive
pursuant to this sentence, such that after payment of such additional taxes the Executive shall
have been paid on a net after-tax basis an amount equal to the Parachute Tax Reimbursement. The
amount of any Parachute Tax Reimbursement and of any such gross-up amounts shall be determined by a
public accounting firm, selected by Executive, whose determination, absent manifest error, shall be
treated as conclusive and binding absent a binding determination by a governmental taxing authority
that a greater amount of taxes is payable by the Executive.

28

 

All fees and expenses of any accounting firm selected under this Section 4(b) shall be borne solely
by Employer.

(c) Claims. If a Taxing Authority makes a claim against you which, if successful, would
require the Company to make a payment under this Section 4, you agree to contest the claim on
request of the Company subject to the following conditions:

	(i)	 	You shall notify the Company of any such claim within ten days of becoming aware thereof. In
the event that the Company desires the claim to be contested, it shall promptly (but in no
event more than 30 days after the notice from you or such shorter time as the Taxing Authority
may specify for responding to such claim) request you to contest the claim. You shall not
make any payment of any tax which is the subject of the claim before you have given the notice
or during the 30 day period thereafter unless you receive written instructions from the
Company to make such payment together with an advance of funds sufficient to make the
requested payment plus any amounts payable under this Section 4 determined as if such advance
were an Excise Tax subject to the Parachute Tax Reimbursement and related gross-up under
Section 4(b), in which you will act promptly in accordance with such instructions; and
	 
	(ii)	 	If the Company so requests, you will contest the claim by either paying the tax claimed and
suing for a refund in the appropriate court or contesting the claim in the United States Tax
Court or other appropriate court, as directed by the Company; provided,
however, that any request by the Company for you to pay the

29

 

	 	 	tax shall be accompanied by an advance from the Company to you of funds sufficient to make
the requested payment plus any amounts under this Section 4 determined as if such advance
were an Excise Tax subject to the Parachute Tax Reimbursement and related gross-up under
Section 4(b). If directed by the Company in writing you will take all action necessary to
compromise or settle the claim, but in no event will you compromise or settle the claim or
cease to contest the claim without the written consent of the Company; provided,
however, that you may take any such action if you waive in writing your right to a
payment under this Section 4 for any amounts payable in connection with such claim. You
agree to cooperate in good faith with the Company in contesting the claim and to comply
with any reasonable request from the Company concerning the contest of the claim, including
the pursuit of administrative remedies, the appropriate forum for any judicial proceedings,
and the legal basis for contesting the claim. Upon request of the Company, you shall take
appropriate appeals of any judgment or decision that would require the Company to make a
payment under this Section 4. Provided that you are in reasonable compliance with the
provisions of this subparagraph, the Company shall be liable for and indemnify you against
any loss in connection with, and all costs and expenses, including attorneys’ and
accountants’ fees, which may be incurred as a result of, contesting the claim, and shall
provide to you within 30 days after each written request therefor by you cash advances or
reimbursement for all such costs and expenses actually incurred or reasonably expected to
be incurred by you as a result of contesting the claim.

30

 

Section 5: Indemnification. In addition to any rights to indemnification to which
Executive is entitled under Employer’s Articles of Incorporation and Bylaws, Employer shall
indemnify Executive at all times during and after the term of this Agreement to the maximum
extent permitted under the Delaware General Corporation Law and any successor provision thereof
and any other applicable corporate law, and shall pay Executive’s expenses in defending any
civil or criminal action, suit or proceeding in advance of the final disposition of such
action, suit or proceeding and any appeal thereof, to the maximum extent permitted under such
applicable laws. Employer shall use reasonable efforts to maintain at all times Directors and
Officers Coverage comparable to its existing Directors and Officers Coverage, if the same can
be obtained at a reasonable cost in comparison to the cost of the then existing coverage, to
cover all or a portion of the foregoing liability.

Agreement may be amended unless such amendment is set forth in a writing that expressly refers to

representative of the Employer.

executors, administrators, successors and assigns of the parties hereto.

this Agreement to enforce any of its terms, or in any appeal therefrom, it is agreed that
Executive shall be entitled to reasonable attorneys fees to be fixed by the trial court and/or
appellate court.

32

Agreement, the day of the act, event or default from which the designated period of time begins to

with any of the terms, covenants or conditions of this Agreement shall not be deemed a waiver of

right or power at any other time or times.

more counterparts, each of which will be deemed to be an original copy of this Agreement and all of
which, when taken together, will be deemed to constitute one and the same agreement. This

Class A-3B, Class A-3C1, Class A-3C2 and Class A-3D Certificates, (ii) the Class

                                     REMIC 1

                As provided herein, the Trustee will make an election to treat
the segregated pool of assets consisting of the Mortgage Loans and certain other
related assets subject to this Agreement (but exclusive of the Group 3
Pre-Funding Account, the Interest Rate Swap Agreement, the Swap Account, the Cap
Carryover Amounts, the Prepayment Charges, the Originator Prepayment Charge
Payment Amounts and the Servicer Prepayment Charge Payment Amounts) as a real
estate investment conduit (a "REMIC") for federal income tax purposes, and such
segregated pool of assets will be designated as "REMIC 1." The Class R-1
Interest will represent the sole class of "residual interests" in REMIC 1 for
purposes of the REMIC Provisions under federal income tax law. The following
table irrevocably sets forth the designation, the Uncertificated REMIC 1
Pass-Through Rate, the initial Uncertificated Principal Balance, and solely for
purposes of satisfying Treasury Regulations Section 1.860G-1(a)(4)(iii), the
"latest possible maturity date" for each of the REMIC 1 Regular Interests. None
of the REMIC 1 Regular Interests will be certificated.

        office, has been lost or is not otherwise available, a copy of such
        Mortgage or power of attorney, as the case may be, certified to be a
        true and complete copy of the original submitted for recording;

                (iii) an original Assignment (which may be in blank), in form

        instead, the Servicer shall take all actions as are necessary to cause
        the Trust to be shown as the owner of the related Mortgage Loan on the
        records of MERS for purposes of the system of recording transfers of
        beneficial ownership of mortgages maintained by MERS;

or (iv) above have as of the Closing Date (or the Additional Transfer Date, with
respect to the Additional Group 3 Mortgage Loans) been submitted for recording
but either (x) has not been returned from the applicable public recording office
or (y) has been lost or such public recording office has retained the original

document to the Trustee. If the Seller does not cure such defect or deliver such
missing document within such time period, the Seller shall either repurchase or
substitute for such Mortgage Loan in accordance with Section 2.03.

                The Depositor herewith delivers to the Trustee executed copies
of the Originator Mortgage Loan Purchase Agreements and the Mortgage Loan
Purchase Agreement.

                The Depositor hereby directs the Trustee to execute, deliver and
perform its obligations, on behalf of the Trust, under the Interest Rate Swap
Agreement and to make the representations of the Trust contained therein.

                It is agreed and understood by the parties hereto that it is not
intended that any mortgage loan be included in the Trust that is a "High-Cost
Home Loan" as defined in any of (i) the New Jersey Home Ownership Act effective
November 27, 2003, (ii) the New Mexico Home Loan Protection Act, effective
January 1, 2004, (iii) the Massachusetts Predatory Home Loan Practices Act,
effective November 7, 2004 or (iv) the Indiana Home Loan Practices Act,

                Concurrently with the execution and delivery of this Agreement,
the Depositor shall deliver the Mortgage Loan Schedule to the Trustee and the
Servicer. The Depositor and the Trustee shall provide a copy of the Mortgage
Loan Schedule to any Certificateholders upon written request made to it at the
addresses set forth on Exhibit D, as the same may be amended from time to time
by written notice from such party to the other parties hereto.

                Section 2.02   Acceptance by Trustee.

                The Trustee acknowledges the receipt of, subject to the
provisions of Section 2.01 and subject to the review described below and any
exceptions noted on the exception report described in the next paragraph below,
the documents referred to in Section 2.01 above and all other assets included in
the definition of "Trust Fund" and declares that it holds and will hold such
documents and the other documents delivered to it constituting a Mortgage File,
and that it holds or will hold all such assets and such other assets included in
the definition of "Trust Fund" in trust for the exclusive use and benefit of all
present and future Certificateholders.

                The Trustee agrees, for the benefit of the Certificateholders,
to review each Mortgage File within 60 days after the Closing Date, with respect
to each Initial Mortgage Loan, or the Additional Transfer Date, with respect to
each Additional Group 3 Mortgage Loan (or, with respect to any document
delivered after the Startup Day (in the case of the Initial Mortgage Loans) or
the Additional Transfer Date (in the case of the Additional Group 3 Mortgage
Loans), within 60 days of receipt and with respect to any Eligible Substitute
Mortgage Loan, within 60 days after the assignment thereof) and to certify in
substantially the form attached hereto as Exhibit F-1 that, as to each Initial
Mortgage Loan listed in the Mortgage Loan Schedules (other than any Mortgage
Loan paid in full or any Mortgage Loan specifically identified in the exception
report annexed thereto as not being covered by such certification), (i) all
documents required to be delivered to it pursuant to Section 2.01 of this
Agreement are in its possession, (ii) such documents have been reviewed by it
and have not been mutilated, damaged or torn and relate to such Mortgage Loan
and (iii) based on its examination and only as to the foregoing, the information
set forth in the Mortgage Loan Schedules that corresponds to items (1), (2),
(10) and (22) of the Mortgage Loan Schedules accurately reflects information set
forth in the Mortgage File. It is herein acknowledged that, in conducting such
review, the Trustee is under no duty or obligation to inspect, review or examine
any such documents, instruments, certificates or other papers to determine that
they are genuine, enforceable, or appropriate for the represented purpose or
that they have actually been recorded or that they are other than what they
purport to be on their face.

                Prior to the first anniversary date of this Agreement the
Trustee shall deliver to the Depositor, the Servicer and the NIMS Insurer a
final certification in the form annexed hereto as Exhibit F-2 evidencing the
completeness of the Mortgage Files, with any applicable exceptions noted
thereon.

                If in the process of reviewing the Mortgage Files and making or
preparing, as the case may be, the certifications referred to above, the Trustee
finds any document or documents constituting a part of a Mortgage File to be
missing or defective in any material respect, at the conclusion of its review
the Trustee shall so notify the Seller, the Depositor, the NIMS Insurer and the
Servicer. In addition, upon the discovery by the Originators, the Seller, the
Depositor, the NIMS Insurer, the Trustee or the Servicer (or upon receipt by the
Trustee of written notification of such breach) of a breach of any of the
representations and warranties made by the related Originator in the applicable
Originator Mortgage Loan Purchase Agreement or the Seller in the Mortgage Loan
Purchase Agreement or an Additional Mortgage Loan Purchase Agreement in respect
of any Mortgage Loan which materially adversely affects such Mortgage Loan or
the interests of the related Certificateholders in such Mortgage Loan, the party
discovering such breach shall give prompt written notice to the other parties.
Notwithstanding the foregoing, any breach of a Deemed Material and Adverse
Representation with respect to a Group 1 Mortgage Loan or Group 2 Mortgage Loan
shall automatically be deemed to materially and adversely affect such Mortgage
Loan or the interest of the related Certificateholders therein.

                The Depositor and the Trustee intend that the assignment and
transfer herein contemplated constitute a sale of the Mortgage Loans and the
Related Documents, conveying good title thereto free and clear of any liens and
encumbrances, from the Depositor to the Trustee and that such property not be
part of the Depositor's estate or property of the Depositor in the event of any
insolvency by the Depositor. In the event that such conveyance is deemed to be,
or to be made as security for, a loan, the parties intend that the Depositor
shall be deemed to have granted and does hereby grant to the Trustee, on behalf
of the Trust, a first priority perfected security interest in all of the
Depositor's right, title and interest in and to the Initial Mortgage Loans and
the Related Documents, and that this Agreement shall constitute a security
agreement under applicable law.

                Section 2.03   Repurchase or Substitution of Mortgage Loans by
the Originators or the Seller.

                (a) Upon discovery or receipt of written notice of any
materially defective document in, or that a document is missing from, a Mortgage
File or of the breach by the Originators or the Seller of any representation or
warranty under the related Originator Mortgage Loan Purchase Agreement, the
Mortgage Loan Purchase Agreement or Additional Mortgage Loan Purchase Agreement,
as applicable, in respect of any Mortgage Loan which materially adversely
affects the value of such Mortgage Loan, Prepayment Charge or the interest
therein of the Certificateholders, the Trustee shall promptly notify the
applicable Originator or the Seller, as the case may be, the Servicer and the
NIMS Insurer of such defect, missing document or breach and request that, in the
case of a defective or missing document, the Seller cure such defect or deliver
such missing document within 120 days from the date the Seller was notified of
such missing document or defect or, in the case of a beach of a representation
or warranty, request the related Originator or the Seller, as applicable, cure
such breach within 90 days from the date the applicable Originator or the
Seller, as the case may be, was notified of such breach. Notwithstanding the
foregoing, any breach of a Deemed Material and Adverse Representation with
respect to a Group 1 Mortgage Loan or Group 2 Mortgage Loan shall automatically
be deemed to materially and adversely affect such Mortgage Loan or the interest
of the related Certificateholders therein. If the Seller does not deliver such
missing document or cure such defect or if the related Originator or the Seller,
as applicable, does not cure such breach in all material respects during such
period, the Trustee shall enforce such Originator's or the Seller's obligation,
as the case may be, under the applicable Originator Mortgage Loan Purchase
Agreement or the Mortgage Loan Purchase Agreement, or Additional Mortgage Loan
Purchase Agreement as applicable, and cause such Originator or the Seller, as
applicable, to repurchase such Mortgage Loan from the Trust Fund at the Purchase
Price on or prior to the Determination Date following the expiration of such
period (subject to Section 2.03(d)). The Purchase Price for the repurchased
Mortgage Loan shall be deposited in the Collection Account, and the Trustee,
upon receipt of written notice from the Servicer of such deposit, shall release
to the related Originator or the Seller, as applicable, the related Mortgage
File and shall execute and deliver such instruments of transfer or assignment,
in each case without recourse, as such Originator or the Seller, as applicable,
shall furnish to it and as shall be necessary to vest in such Originator or the
Seller, as the case may be, any Mortgage Loan released pursuant hereto and the
Trustee shall have no further responsibility with regard to such Mortgage File.
In lieu of repurchasing any such Mortgage Loan as provided above, the related
Originator or the Seller, as the case may be, may cause such Mortgage Loan to be
removed from the Trust Fund (in which case it shall become a Defective Mortgage
Loan) and substitute one or more Eligible Substitute Mortgage Loans in the
manner and subject to the limitations set forth in Section 2.03(c).

                With respect to the representations and warranties set forth in
the applicable Originator Mortgage Loan Purchase Agreement, the Mortgage Loan
Purchase Agreement or the Additional Mortgage Loan Purchase Agreement that are
made to the best of the related Originator's or the Seller's knowledge, as
applicable, or as to which such Originator or the Seller, as the case may be,
has no knowledge, if it is discovered by the Depositor, the Servicer, the NIMS
Insurer or the Trustee that the substance of such representation and warranty is
inaccurate and such inaccuracy materially and adversely affects the value of the
related Mortgage Loan, Prepayment Charge or the interest therein of the
Certificateholders then, notwithstanding such Originator's or the Seller's lack
of knowledge with respect to the substance of such representation and warranty
being inaccurate at the time the representation or warranty was made, such
inaccuracy shall be deemed a breach of the applicable representation or
warranty.

                It is understood and agreed that the representations and
warranties set forth in the applicable Originator Mortgage Loan Purchase
Agreement, the Mortgage Loan Purchase Agreement or Additional Mortgage Loan
Purchase Agreement shall survive delivery of the Mortgage Files to the Trustee
and the Closing Date and shall inure to the benefit of the Certificateholders
notwithstanding any restrictive or qualified endorsement or assignment. It is
understood and agreed that the obligations of the Originators and the Seller set
forth in this Section 2.03(a) to cure, substitute for or repurchase a Mortgage
Loan pursuant to the related Originator Mortgage Loan Purchase Agreement, the
Mortgage Loan Purchase Agreement or Additional Mortgage Loan Purchase Agreement,
as applicable, and to pay the Reimbursement Amount constitute the sole remedies
available to the Certificateholders and to the Trustee on their behalf
respecting a breach of the representations and warranties contained in the
Originator Mortgage Loan Purchase Agreement, Mortgage Loan Purchase Agreement
and Additional Mortgage Loan Purchase Agreement.

                The representations and warranties of the applicable Originator
with respect to the Mortgage Loans in the respective Originator Mortgage Loan
Purchase Agreement, which have been assigned to the Trustee hereunder, were made
as of the dates specified in the applicable Originator Mortgage Loan Purchase
Agreement. To the extent that any fact, condition or event with respect to a
Mortgage Loan constitutes a breach of both (i) a representation or warranty of
the applicable Originator under the respective Originator Mortgage Loan Purchase
Agreement and (ii) a representation or warranty of the Seller under the Mortgage
Loan Purchase Agreement or Additional Mortgage Loan Purchase Agreement (other
than Seller's representations with respect to predatory and abusive lending laws
in Section 3.01(k) and 3.01(s) of the Mortgage Loan Purchase Agreement), the
only right or remedy of the Trustee or of any Certificateholder shall be the
Trustee's right to enforce the obligations of the applicable Originator under
any applicable representation or warranty made by it. The Trustee acknowledges
that the Seller shall have no obligation or liability with respect to any breach
of a representation or warranty made by it with respect to the Mortgage Loans
(except as otherwise set forth in this paragraph) if the fact, condition or
event constituting such breach also constitutes a breach of a representation or
warranty made by the applicable Originator in the respective Originator Mortgage
Loan Purchase Agreement, without regard to whether such Originator fulfills its
contractual obligations in respect of such representation or warranty. In
addition, to the extent that any fact, condition or event with respect to a
Mortgage Loan constitutes a breach of both (x) the Option One Mortgage
Corporation's representation with respect to predatory and abusive lending laws
in Section 3.03(i) or 3.03(ddd) of the Option One Sale Agreement or Ownit
Mortgage's representations and warranties set forth in clauses (g), (tt), (uu),
(vv) or (nnn) of Section 9.02 of the Ownit Sale Agreement and (y) the Seller's
representation with respect to predatory and abusive lending laws in Section
3.01(k) or 3.01(s) of the Mortgage Loan Purchase Agreement, such Originator
shall be obligated to pay the Reimbursement Amount relating to such Mortgage
Loan, and, to the extent such Originator fails to do so, the Trustee shall be
entitled to enforce the Seller's obligation to pay such Reimbursement Amount. In
any event, the Reimbursement Amount shall be delivered to the Servicer for
deposit into the Collection Account within 10 days from the date the Seller was
notified by the Trustee of the Reimbursement Amount.

                (b) Within 90 days of the earlier of discovery by the Servicer
or receipt of notice by the Servicer of the breach of any representation,
warranty or covenant of the Servicer set forth in Section 2.05 which materially
and adversely affects the interests of the Certificateholders in any Mortgage
Loan, the Servicer shall cure such breach in all material respects.

                (c) Any substitution of Eligible Substitute Mortgage Loans for
Defective Mortgage Loans made pursuant to Section 2.03(a) must be effected prior
to the last Business Day that is within two years after the Closing Date. As to
any Defective Mortgage Loan for which an Originator or the Seller substitutes an
Eligible Substitute Mortgage Loan or Loans, such substitution shall be effected
by such Originator or the Seller, as applicable, delivering to the Trustee for
such Eligible Substitute Mortgage Loan or Loans, the Mortgage Note, the
Mortgage, the Assignment to the Trustee, and such other documents and
agreements, with all necessary endorsements thereon, as are required by Section
2.01, together with an Officers' Certificate providing that each such Eligible
Substitute Mortgage Loan satisfies the definition thereof and specifying the
Substitution Adjustment Amount (as described below), if any, in connection with
such substitution. The Trustee shall acknowledge receipt for such Eligible
Substitute Mortgage Loan or Loans and, within ten Business Days thereafter,
shall review such documents as specified in Section 2.02 and deliver to the
Servicer and the NIMS Insurer, with respect to such Eligible Substitute Mortgage
Loan or Loans, a certification substantially in the form attached hereto as
Exhibit F-1, with any applicable exceptions noted thereon. Within one year of
the date of substitution, the Trustee shall deliver to the Servicer and the NIMS
Insurer a certification substantially in the form of Exhibit F-2 hereto with
respect to such Eligible Substitute Mortgage Loan or Loans, with any applicable
exceptions noted thereon. Monthly Payments due with respect to Eligible
Substitute Mortgage Loans in the month of substitution are not part of the Trust
Fund and will be retained by the related Originator or the Seller, as
applicable. For the month of substitution, distributions to Certificateholders
will reflect the collections and recoveries in respect of such Defective
Mortgage Loan in the Collection Period or Prepayment Period, as applicable,
preceding the date of substitution and the Depositor, an Originator or the
Seller, as the case may be, shall thereafter be entitled to retain all amounts
subsequently received in respect of such Defective Mortgage Loan. The Depositor
shall give or cause to be given written notice to the Certificateholders and the
NIMS Insurer that such substitution has taken place, shall amend the applicable
Mortgage Loan Schedule to reflect the removal of such Defective Mortgage Loan
from the terms of this Agreement and the substitution of the Eligible Substitute
Mortgage Loan or Loans and shall deliver a copy of such amended Mortgage Loan
Schedule to the Trustee and the NIMS Insurer. Upon such substitution, such
Eligible Substitute Mortgage Loan or Loans shall constitute part of the Mortgage
Pool and shall be subject in all respects to the terms of this Agreement and, in
the case of a substitution effected by an Originator or the Seller, the
applicable Originator Mortgage Loan Purchase Agreement or the Mortgage Loan
Purchase Agreement or Additional Mortgage Loan Purchase Agreement, as the case
may be, including, in the case of a substitution effected by such Originator or
the Seller, all applicable representations and warranties thereof included in
such Originator Mortgage Loan Purchase Agreement, Mortgage Loan Purchase
Agreement or Additional Mortgage Loan Purchase Agreement, as the case may be, as
of the date of substitution.

                For any month in which an Originator or the Seller substitutes
one or more Eligible Substitute Mortgage Loans for one or more Defective
Mortgage Loans, the Servicer will determine the amount (the "Substitution
Adjustment Amount"), if any, by which the aggregate Purchase Price of all such
Defective Mortgage Loans exceeds the aggregate, as to each such Eligible
Substitute Mortgage Loan, of the principal balance thereof as of the date of
substitution, together with one month's interest on such principal balance at
the applicable Net Mortgage Interest Rate. On the date of such substitution, the
related Originator or the Seller, as the case may be, will deliver or cause to
be delivered to the Servicer for deposit in the Collection Account an amount
equal to the Substitution Adjustment Amount, if any, and the Trustee, upon
receipt of the related Eligible Substitute Mortgage Loan or Loans and notice by
the Servicer of such deposit, shall release to such Originator or the Seller, as
applicable, the related Mortgage File or Files and shall execute and deliver
such instruments of transfer or assignment, in each case without recourse, as
such Originator or the Seller, as the case may be, shall deliver to it and as
shall be necessary to vest therein any Defective Mortgage Loan released pursuant
hereto. In addition, such Originator or the Seller, as applicable, shall obtain
at its own expense and deliver to the Trustee and the NIMS Insurer an Opinion of
Counsel to the effect that such substitution will not cause (a) any federal tax
to be imposed on the Trust Fund, including without limitation, any federal tax
imposed on "prohibited transactions" under Section 860F(a)(l) of the Code or on
"contributions after the startup date" under Section 860G(d)(l) of the Code, or
(b) any REMIC to fail to qualify as a REMIC at any time that any Certificate is
outstanding. If such Opinion of Counsel can not be delivered, then such
substitution may only be effected at such time as the required Opinion of
Counsel can be given.

                (d) Upon discovery by an Originator, the Seller, the Servicer,
the NIMS Insurer or the Trustee that any Mortgage Loan does not constitute a
"qualified mortgage" within the meaning of Section 860G(a)(3) of the Code, the
party discovering such fact shall within two Business Days give written notice
thereof to the other parties. In connection therewith, such Originator or the
Seller, as applicable, shall repurchase or, subject to the limitations set forth
in Section 2.03(c), substitute one or more Eligible Substitute Mortgage Loans
for the affected Mortgage Loan within 90 days of the earlier of discovery or
receipt of such notice with respect to such affected Mortgage Loan. In addition,
upon discovery that a Mortgage Loan is defective in a manner that would cause it
to be a "defective obligation" within the meaning of Treasury Regulations
relating to REMICs, such Originator or the Seller, as the case may be, shall
cure the defect or make the required purchase or substitution no later than 90
days after the discovery of the defect. Any such repurchase or substitution
shall be made in the same manner as set forth in Section 2.03(a). The Trustee
shall reconvey to such Originator or the Seller, as applicable, the Mortgage
Loan to be released pursuant hereto in the same manner, and on the same terms
and conditions, as it would a Mortgage Loan repurchased for breach of a
representation or warranty.

(e) If a Mortgagor is forty-five (45) days or more delinquent with respect to a
Mortgage Loan's first Monthly Payment that was due the Seller after its initial
purchase under the Option One Sale Agreement, the Servicer, at the Seller's
option, shall repurchase such Mortgage Loan at the purchase price set forth in
the Option One Sale Agreement plus accrued and unpaid interest thereon from the
date to which interest was last paid through the last day of the month in which
such repurchase takes place at the applicable Mortgage Loan Remittance Rate (as
such term is defined in the Option One Sale Agreement); provided, however, the
Servicer's obligation to repurchase any such Mortgage Loan pursuant to this
paragraph shall expire 150 days following the related Closing Date (as such term
is defined in the Option One Sale Agreement)."

                Section 2.04   Conveyance of the Additional Group 3 Mortgage
Loans.

                (a) Subject to the conditions set forth in paragraph (b) below,
in consideration of the Trustee's delivery on the Additional Transfer Dates to
or upon the order of the Depositor of all or a portion of the balance of funds
in the Group 3 Pre-Funding Account, the Depositor shall on any Additional
Transfer Date sell, transfer, assign, set over and convey without recourse to
the Trust Fund but subject to the other terms and provisions of this Agreement
all of the right, title and interest of the Depositor in and to (i) the
Additional Group 3 Mortgage Loans identified on the Schedule of Additional
Mortgage Loans attached to the related Additional Transfer Instrument delivered

of interest and principal due after the Subsequent Cut-off Date and (iii) all
items with respect to such Additional Group 3 Mortgage Loans to be delivered
pursuant to Section 2.01 and the other items in the related Mortgage Files;
provided, however, that the Depositor reserves and retains all right, title and
interest in and to principal received and interest accruing on the Additional
Group 3 Mortgage Loans prior to the related Subsequent Cut-off Date. The
transfer to the Trustee for deposit in the Mortgage Pool by the Depositor of the
Additional Group 3 Mortgage Loans identified on the Schedule of Additional
Mortgage Loans shall be absolute and is intended by the Depositor, the Servicer,
the Trustee and the Certificateholders to constitute and to be treated as a sale
of the Additional Group 3 Mortgage Loans by the Depositor to the Trust Fund. The
related Mortgage File for each Additional Group 3 Mortgage Loan shall be
delivered to the Trustee at least three Business Days prior to the related
Additional Transfer Date.

                The purchase price paid by the Trustee from amounts released
from the Group 3 Pre-Funding Account shall be one-hundred percent (100%) of the
aggregate Principal Balance of the related Additional Group 3 Mortgage Loans so
transferred (as identified on the Mortgage Loan Schedule provided by the
Depositor). This Agreement shall constitute a fixed-price purchase contract in
accordance with Section 860G(a)(3)(A)(ii) of the Code.

                (b) The Depositor shall transfer to the Trustee for deposit in
the Mortgage Pool the Additional Group 3 Mortgage Loans and the other property
and rights related thereto as described in paragraph (a) above, and the Trustee
shall release funds from the Group 3 Pre-Funding Account only upon the
satisfaction of each of the following conditions on or prior to the related
Additional Transfer Date:

                (i) the Depositor shall have provided the Trustee, the NIMS
        Insurer and the Rating Agencies with a timely Addition Notice and shall

        NIMS Insurer a duly executed Additional Transfer Instrument, which shall
        include a Schedule of Additional Mortgage Loans listing the Additional
        Group 3 Mortgage Loans, and the Depositor, shall have delivered a
        computer file containing such schedule to the Trustee at least three
        Business Days prior to the related Additional Transfer Date;

                (iii) as of each Additional Transfer Date, as evidenced by
        delivery of the Additional Transfer Instrument, substantially in the

        been rendered insolvent by such transfer nor shall it be aware of any
        pending insolvency;

                (iv) such sale and transfer shall not result in a material
        adverse tax consequence to the Trust Fund or the Certificateholders;

                (v) the Funding Period shall not have terminated;

                (vi) the Depositor shall not have selected the Additional Group
        3 Mortgage Loans in a manner that it believed to be adverse to the
        interests of the Certificateholders;

                (vii) the Depositor shall have delivered to the Trustee and the
        NIMS Insurer an Additional Transfer Instrument confirming the
        satisfaction of the conditions precedent specified in this Section 2.04
        and, pursuant to the Additional Transfer Instrument, assigned to the
        Trustee without recourse for the benefit of the Certificateholders all
        the right, title and interest of the Depositor, in, to and under the
        Additional Mortgage Loan Purchase Agreement, to the extent of the
        Additional Group 3 Mortgage Loans;

                (viii) with respect to the last Additional Transfer Date, the
        Depositor shall have delivered to the Trustee and the NIMS Insurer a
        letter from an Independent accountant (with copies provided to each
        Rating Agency) stating that the characteristics of the Additional Group
        3 Mortgage Loans conform to the characteristics set forth in clauses (i)
        through (xi) of paragraph (c) below and to the characteristics set forth
        in paragraph (d) below; and

                (ix) the Depositor shall have received the consent of the NIMS

Combined Loan-to-Value Ratio greater than 100.00%; (v) all of the Additional
Group 3 Mortgage Loans will have, as of the Subsequent Cut-off Date, a weighted
average term to stated maturity not in excess of 360 months; (vi) each

                (e) Notwithstanding the foregoing, any Additional Group 3
Mortgage Loan may be rejected by (i) the NIMS Insurer or (ii) any Rating Agency
if the inclusion of any such Additional Group 3 Mortgage Loan would adversely
affect the ratings of any Class of Certificates. At least one Business Day prior
to the Additional Transfer Date, each Rating Agency shall notify the Trustee as

transfer on the Additional Transfer Date; provided, however, that the Depositor
shall have delivered to each Rating Agency at least three Business Days prior to
such Additional Transfer Date a computer file acceptable to each Rating Agency

                Section 2.05   Representations, Warranties and Covenants of the
Servicer.

                The Servicer hereby represents, warrants and covenants to the
Trustee, for the benefit of each of the Trustee and the Certificateholders and
to the Depositor and the NIMS Insurer that as of the Closing Date or as of such
date specifically provided herein:

                (i) The Servicer is a corporation duly organized, validly
        existing and in good standing under the laws of the State of California
        and has all licenses necessary to carry on its business as now being
        conducted, except for such licenses, certificates and permits the
        absence of which, individually or in the aggregate, would not have a
        material adverse effect on the ability of the Servicer to conduct its
        business as it is presently conducted, and is licensed, qualified and in
        good standing in the states where the Mortgaged Property is located if
        the laws of such state require licensing or qualification in order to
        conduct business of the type conducted by the Servicer or to ensure the
        enforceability or validity of each Mortgage Loan; the Servicer has the
        power and authority to execute and deliver this Agreement and to perform
        in accordance herewith; the execution, delivery and performance of this
        Agreement (including all instruments of transfer to be delivered
        pursuant to this Agreement) by the Servicer and the consummation of the
        transactions contemplated hereby have been duly and validly authorized;
        and all requisite corporate action has been taken by the Servicer to
        make this Agreement valid and binding upon the Servicer in accordance
        with its terms;

                (ii) The consummation of the transactions contemplated by this
        Agreement are in the ordinary course of business of the Servicer and
        will not result in the breach of any term or provision of the articles
        of incorporation or by-laws of the Servicer or result in the breach of
        any term or provision of, or conflict with or constitute a default under
        or result in the acceleration of any obligation under, any agreement,
        indenture or loan or credit agreement or other instrument to which the
        Servicer or its property is subject, or result in the violation of any
        law, rule, regulation, order, judgment or decree to which the Servicer
        or its property is subject;

                (iii) The Servicer is an approved seller/servicer of
        conventional residential mortgage loans for Fannie Mae or Freddie Mac,
        with the facilities, procedures, and experienced personnel necessary for
        the sound servicing of mortgage loans of the same type as the Mortgage
        Loans. The Servicer is a HUD approved mortgagee pursuant to Section 203
        of the National Housing Act and is in good standing to sell mortgage
        loans to and service mortgage loans for Fannie Mae or Freddie Mac, and
        no event has occurred, including but not limited to a change in
        insurance coverage, which would make the Servicer unable to comply with
        Fannie Mae or Freddie Mac eligibility requirements or which would
        require notification to either Fannie Mae or Freddie Mac;

                (iv) This Agreement, and all documents and instruments
        contemplated hereby which are executed and delivered by the Servicer,
        constitute and will constitute valid, legal and binding obligations of
        the Servicer, enforceable in accordance with their respective terms,
        except as the enforcement thereof may be limited by applicable
        bankruptcy, insolvency, reorganization, moratorium or other similar laws
        affecting the enforcement of creditors' rights generally (whether
        considered in a proceeding at law or in equity);

                (v) The Servicer does not believe, nor does it have any reason
        or cause to believe, that it cannot perform each and every covenant
        contained in this Agreement;

                (vi) There is no action, suit, proceeding or investigation
        pending or, to its knowledge, threatened against the Servicer that,
        either individually or in the aggregate, may result in any material
        adverse change in the business, operations, financial condition,
        properties or assets of the Servicer, or in any material impairment of
        the right or ability of the Servicer to carry on its business
        substantially as now conducted, or in any material liability on the part
        of the Servicer, or that would draw into question the validity or
        enforceability of this Agreement or of any action taken or to be taken
        in connection with the obligations of the Servicer contemplated herein,
        or that would be likely to impair materially the ability of the Servicer
        to perform under the terms of this Agreement;

                (vii) No consent, approval or order of any court or governmental
        agency or body is required for the execution, delivery and performance
        by the Servicer of or compliance by the Servicer with this Agreement or
        the consummation of the transactions contemplated by this Agreement,
        except for such consents, approvals, authorizations and orders, if any,
        that have been obtained;

                (viii) No information in this Agreement provided by the Servicer
        nor any information, certificate of an officer, statement furnished in
        writing or report delivered to the Trustee by the Servicer in connection
        with the transactions contemplated hereby contains or will contain any
        untrue statement of a material fact or omits or will omit to state a
        material fact necessary in order to make the statements contained
        therein, in light of the circumstances under which they were made, not
        misleading;

                (ix) The Servicer has fully furnished, and shall continue to
        fully furnish for so long as it is servicing the Mortgage Loans
        hereunder, in accordance with the Fair Credit Reporting Act and its
        implementing regulations, accurate and complete information on the
        Mortgagor credit files to Equifax, Experian and Trans Union Credit
        Information Company on a monthly basis;

                (x) Except as otherwise disclosed in the Prospectus Supplement,
        no legal or governmental proceedings are pending (or known to be
        contemplated) against the Servicer that would be material to
        Certificateholders;

                (xi) Except as otherwise disclosed in the Prospectus Supplement,
        the Servicer is not aware and has not received notice that any default,
        early amortization or other performance triggering event has occurred as
        to any other securitization due to any act or failure to act of the
        Servicer under such securitization;

                (xii) Except as otherwise disclosed in the Prospectus
        Supplement, the Servicer has not been terminated as servicer in a
        residential mortgage loan securitization, either due to a servicing
        default or to application of a servicing performance test or trigger;

                (xiii) Except as otherwise disclosed in the Prospectus
        Supplement, no material noncompliance with the applicable servicing
        criteria with respect to other securitizations of residential mortgage
        loans involving the Servicer as a servicer has been disclosed or
        reported by the Servicer within the past three (3) years;

                (xiv) Except as otherwise disclosed in the Prospectus
        Supplement, no material changes to the Servicer's policies or procedures
        with respect to the servicing function it will perform under this
        Agreement for mortgage loans of a type similar to the Mortgage Loans
        have occurred during the three-year period immediately preceding the
        date of this Agreement;

                (xv) Except as otherwise disclosed in the Prospectus Supplement,
        there is no material risk that the Servicer's financial condition could
        affect one or more aspects of the performance by the Servicer of its
        servicing obligations under this Agreement in a manner that could have a
        material impact on the performance of the Mortgage Loans or the
        Certificates; and

                (xvi) Except as disclosed in the Prospectus Supplement, there
        are no affiliations, relationships or transactions relating to the
        Servicer and any party identified in Item 1119 of Regulation AB of the
        type described therein.

                It is understood and agreed that the representations, warranties
and covenants set forth in this Section 2.05 shall survive delivery of the
Mortgage Files to the Trustee and shall inure to the benefit of the Trustee, the
Depositor, the NIMS Insurer and the Certificateholders. Upon discovery by any of
the Depositor, the Servicer, the NIMS Insurer or the Trustee of a breach of any
of the foregoing representations, warranties and covenants which materially and
adversely affects the value of any Mortgage Loan, Prepayment Charge or the
interests therein of the Certificateholders, the party discovering such breach
shall give prompt written notice (but in no event later than two Business Days
following such discovery) to the other parties hereto.

                Upon discovery by any of the Depositor, the Servicer or the
Trustee of a breach of any of the representations and warranties set forth in
this Section 2.05, the party discovering such breach shall give prompt written
notice, which shall not exceed two days, to the other parties. The Trustee shall
consult with the Depositor to determine if any such breach is material and any
breach determined by the Depositor to be material shall be included by the
Trustee on the next Distribution Date Statement prepared pursuant to Section
4.06.

                Section 2.06   Representations and Warranties of the Depositor.

                The Depositor represents and warrants to the Trust and the
Trustee on behalf of the Certificateholders and to the Servicer and the NIMS
Insurer as follows:

                (i) This agreement constitutes a legal, valid and binding
        obligation of the Depositor, enforceable against the Depositor in
        accordance with its terms, except as enforceability may be limited by
        applicable bankruptcy, insolvency, reorganization, moratorium or other
        similar laws now or hereafter in effect affecting the enforcement of
        creditors' rights in general and except as such enforceability may be
        limited by general principles of equity (whether considered in a
        proceeding at law or in equity);

                (ii) Immediately prior to the sale and assignment by the
        Depositor to the Trustee on behalf of the Trust of each Initial Mortgage
        Loan, the Depositor had good and marketable title to each Mortgage Loan
        (insofar as such title was conveyed to it by the Seller) subject to no
        prior lien, claim, participation interest, mortgage, security interest,
        pledge, charge or other encumbrance or other interest of any nature;

                (iii) As of the Closing Date, the Depositor has transferred all
        right, title interest in the Initial Mortgage Loans to the Trustee on
        behalf of the Trust;

                (iv) The Depositor has not transferred the Initial Mortgage
        Loans to the Trustee on behalf of the Trust with any intent to hinder,
        delay or defraud any of its creditors;

                (v) The Depositor has been duly incorporated and is validly
        existing as a corporation in good standing under the laws of the State
        of Delaware, with full corporate power and authority to own its assets
        and conduct its business as presently being conducted;

                (vi) The Depositor is not in violation of its certificate of
        incorporation or by-laws or in default in the performance or observance
        of any material obligation, agreement, covenant or condition contained
        in any contract, indenture, mortgage, loan agreement, note, lease or
        other instrument to which the Depositor is a party or by which it or its
        properties may be bound, which default might result in any material
        adverse changes in the financial condition, earnings, affairs or
        business of the Depositor or which might materially and adversely affect
        the properties or assets, taken as a whole, of the Depositor;

                (vii) The execution, delivery and performance of this Agreement
        by the Depositor, and the consummation of the transactions contemplated
        thereby, do not and will not result in a material breach or violation of
        any of the terms or provisions of, or, to the knowledge of the
        Depositor, constitute a default under, any indenture, mortgage, deed of
        trust, loan agreement or other agreement or instrument to which the
        Depositor is a party or by which the Depositor is bound or to which any
        of the property or assets of the Depositor is subject, nor will such
        actions result in any violation of the provisions of the certificate of
        incorporation or by-laws of the Depositor or, to the best of the
        Depositor's knowledge without independent investigation, any statute or
        any order, rule or regulation of any court or governmental agency or
        body having jurisdiction over the Depositor or any of its properties or
        assets (except for such conflicts, breaches, violations and defaults as
        would not have a material adverse effect on the ability of the Depositor
        to perform its obligations under this Agreement);

                (viii) To the best of the Depositor's knowledge without any
        independent investigation, no consent, approval, authorization, order,
        registration or qualification of or with any court or governmental
        agency or body of the United States or any other jurisdiction is
        required for the issuance of the Certificates, or the consummation by
        the Depositor of the other transactions contemplated by this Agreement,
        except such consents, approvals, authorizations, registrations or
        qualifications as (a) may be required under State securities or Blue Sky
        laws, (b) have been previously obtained or (c) the failure of which to
        obtain would not have a material adverse effect on the performance by
        the Depositor of its obligations under, or the validity or
        enforceability of, this Agreement; and

                (ix) There are no actions, proceedings or investigations pending
        before or, to the Depositor's knowledge, threatened by any court,
        administrative agency or other tribunal to which the Depositor is a
        party or of which any of its properties is the subject: (a) which if
        determined adversely to the Depositor would have a material adverse
        effect on the business, results of operations or financial condition of
        the Depositor; (b) asserting the invalidity of this Agreement or the
        Certificates; (c) seeking to prevent the issuance of the Certificates or
        the consummation by the Depositor of any of the transactions
        contemplated by this Agreement, as the case may be; (d) which might
        materially and adversely affect the performance by the Depositor of its
        obligations under, or the validity or enforceability of, this Agreement.

                Section 2.07   Issuance of Certificates and the Uncertificated
Regular Interests.

                The Trustee acknowledges the assignment to it of the Initial
Mortgage Loans and the delivery to it of the Mortgage Files, subject to the
provisions of Sections 2.01 and 2.02, and the Trustee acknowledges the
assignment to it of all other assets included in the Trust Fund, receipt of
which is hereby acknowledged. Concurrently with such assignment and delivery and
in exchange therefor, the Trustee, pursuant to the Written Order to Authenticate
executed by an officer of the Depositor, has executed, and the Certificate
Registrar has authenticated and delivered to or upon the order of the Depositor,
the Certificates (other than the Class CE, Class P and Residual Certificates) in
minimum dollar denominations or $25,000 and integral dollar multiples of $1 in
excess. The Class CE and Class P Certificates are issuable only in minimum
Percentage Interests of 10%. Each Class of Residual Certificate is issuable only
as a single certificate. The Trustee acknowledges the issuance of the
uncertificated REMIC 1 Regular Interests and declares that it holds such regular
interests as assets of REMIC 2. The Trustee acknowledges the issuance of the
uncertificated REMIC 2 Regular Interests and declares that it hold such regular
interests as assets of REMIC 3. The Trustee acknowledges the issuance of the
uncertificated REMIC 3 Regular Interests and declares that it hold such regular
interests as assets of REMIC 4. The Trustee acknowledges the issuance of the
uncertificated Class CE Interest and declares that it hold such regular interest
as assets of REMIC 5. The Trustee acknowledges the obligation of the Class CE
Certificates to pay Cap Carryover Amounts, and declares that it holds the same
as assets of the Grantor Trust on behalf of the Holders of the Class A-1, Class
A-2, Class A-3A, Class A-3B, Class A-3C1, Class A-3C2, Class A-3D, Class M-1,
Class M-2, Class M-3, Class M-4, Class M-5, Class M-6, Class M-7, Class M-8,
Class M-9 and Class B Certificates, respectively, which shall be treated as
beneficially owning the right to receive the Cap Carryover Amounts from the
Grantor Trust. In addition to the assets described in the preceding sentence,
the assets of the Grantor Trust shall also include (i) Prepayment Charges, any
Originator Prepayment Charge Payment Amounts, any Servicer Prepayment Charge
Payment Amounts and the beneficial interest of the Class P Certificates with
respect thereto and (ii) the Interest Rate Swap Agreement, the Swap Account and
the beneficial interest of the Class CE Certificates with respect thereto,
subject to the obligation to pay Cap Carryover Amounts. The interests evidenced
by the Certificates constitute the entire beneficial ownership interest in the
Trust Fund.

                                  ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF THE TRUST FUND

                Section 3.01   Servicer to Act as Servicer.

                The Servicer, as independent contract servicer, shall service
and administer the Mortgage Loans in accordance with this Agreement and the
normal and usual standards of practice of prudent mortgage servicers servicing
similar mortgage loans and, to the extent consistent with such terms, in the
same manner in which it services and administers similar mortgage loans for its
own portfolio, and shall have full power and authority, acting alone, to do or
cause to be done any and all things in connection with such servicing and
administration which the Servicer may deem necessary or desirable and consistent
with the terms of this Agreement (the "Servicing Standard").

                Consistent with the terms of this Agreement, the Servicer may
waive, modify or vary any term of any Mortgage Loan or consent to the
postponement of strict compliance with any such term or in any manner grant
indulgence to any Mortgagor if in the Servicer's reasonable and prudent
determination such waiver, modification, postponement or indulgence is not
materially adverse to the Certificateholders; provided, however, that the
Servicer shall not make future advances and, except as set forth in the
following sentence or Section 3.03, the Servicer shall not permit any
modification with respect to any Mortgage Loan that would (i) change the
Mortgage Interest Rate, defer or forgive the payment thereof of any principal or
interest payments, reduce the outstanding principal amount (except for actual
payments of principal) or extend the final maturity date with respect to such
Mortgage Loan, (ii) affect adversely the status of any REMIC constituting part
of the Trust Fund as a REMIC, or (iii) cause any such REMIC to be subject to a
tax on "prohibited transactions" or "contributions" pursuant to the REMIC
Provisions. In the event that the Mortgagor is in default with respect to the
Mortgage Loan or such default is, in the judgment of the Servicer, reasonably
foreseeable, the Servicer may permit a modification of such Mortgage Loan to
reduce the Principal Balance thereof and/or extend the term, but not beyond the
latest maturity date of any other Mortgage Loan. Notwithstanding the foregoing,
the Servicer shall not permit any modification with respect to any Mortgage Loan
that would both (x) effect an exchange or reissuance of such Mortgage Loan under
Section 1.860G-2(b) of the Treasury Regulations and (y) cause any REMIC
constituting part of the Trust Fund to fail to qualify as a REMIC under the Code
or the imposition of any tax on "prohibited transactions" or "contributions"
after the Startup Day under the REMIC Provisions. The NIMS Insurer's prior
written consent shall be required for any modification, waiver or amendment if
the aggregate number of outstanding Mortgage Loans which have been modified,
waived or amended exceeds 5% of the number of Mortgage Loans as of the Cut-off
Date. Without limiting the generality of the foregoing, the Servicer shall
continue, and is hereby authorized and empowered to execute and deliver on
behalf of itself, and the Trustee, all instruments of satisfaction or
cancellation, or of partial or full release, discharge and all other comparable
instruments, with respect to the Mortgage Loans and with respect to the
Mortgaged Property. The Servicer shall make all required Servicing Advances and
shall service and administer the Mortgage Loans in accordance with Applicable
Regulations, and shall provide to the Mortgagor any reports required to be
provided to them thereby. The Trustee shall execute and deliver to the Servicer
within at least fifteen (15) Business Day of receipt, upon request, any powers
of attorney furnished to it by the Servicer empowering the Servicer to execute
and deliver instruments of satisfaction or cancellation, or of partial or full
release or discharge, and to foreclose upon or otherwise liquidate any Mortgaged
Property, and to appeal, prosecute or defend in any court action relating to the
Mortgage Loans or the Mortgaged Properties, in accordance with this Agreement,
and the Trustee shall execute and deliver such other documents as the Servicer
may request, necessary or appropriate to enable the Servicer to service and
administer the Mortgage Loans and carry out its duties hereunder, in each case
in accordance with Servicing Standard (and the Trustee shall have no liability
for misuse of any such powers of attorney by the Servicer). Notwithstanding
anything contained herein to the contrary, the Servicer shall not without the
Trustee's written consent: (i) initiate any action, suit or proceeding solely
under the Trustee's name without indicating the Servicer's representative
capacity or (ii) take any action with the intent to cause, and which results in,
the Trustee being registered to do business in any state.

                In servicing and administering the Mortgage Loans, the Servicer
shall employ procedures including collection procedures and exercise the same
care that it customarily employs and exercises in servicing and administering
mortgage loans for its own account giving due consideration to accepted mortgage
servicing practices of prudent lending institutions and the Certificateholders'
reliance on the Servicer.

                The Servicer shall give prompt notice to the Trustee of any
action, of which the Servicer has actual knowledge, to (i) assert a claim
against the Trust Fund or (ii) assert jurisdiction over the Trust Fund.

                Notwithstanding anything in this Agreement to the contrary, in
the event of a voluntary Principal Prepayment in full of a Mortgage Loan, the
Servicer may not waive any Prepayment Charge or portion thereof required by the
terms of the related Mortgage Note unless (i)(a) the Servicer determines that
such waiver is standard and customary in servicing similar mortgage loans, (b)
such waiver relates to a default or a reasonably foreseeable default and (c)
would, in the reasonable judgment of the Servicer, maximize recovery of
Liquidation Proceeds for such Mortgage Loan, taking into account the value of
such Prepayment Charge, or (ii) the enforceability thereof is limited (1) by
bankruptcy, insolvency, moratorium, receivership, or other similar law relating
to creditors' rights generally or (2) due to acceleration in connection with a
foreclosure or other involuntary payment. If the Servicer has waived or does not
collect all or a portion of a Prepayment Charge relating to a voluntary
Principal Prepayment in full due to any action or omission of the Servicer,
other than as provided above, the Servicer shall, on the date on which the
Principal Prepayment in full is remitted to the Trustee, deliver to the Trustee
the Servicer Prepayment Charge Amount with respect to such Mortgage Loan for
distribution in accordance with the terms of this Agreement.

                In the event that a Prepayment Charge due with respect to any
Mortgage Loan is not timely received by the Servicer, the Servicer shall use
commercially reasonable efforts to determine whether the related Originator is
obligated to pay a related Originator Prepayment Charge Payment Amount, and if
the Servicer determines that a Originator Prepayment Charge Payment Amount is
due, the Servicer shall promptly notify the related Originator, and the Servicer
shall enforce the Originator's obligations to pay in a timely manner any such
Originator Prepayment Charge Payment Amounts and, to the extent that such
amounts are received by the Servicer, shall cause such amounts to be deposited
into the Collection Account within one Business Day of receipt.

                Section 3.02   Collection of Mortgage Loan Payments.

                Continuously from the date hereof until the principal and
interest on all Mortgage Loans are paid in full or as long as the Mortgage Loan
remains subject to this Agreement, the Servicer will diligently collect all
payments due under each Mortgage Loan when the same shall become due and payable
and shall, to the extent such procedures shall be consistent with this Agreement
and Applicable Regulations, follow such collection procedures as it follows with
respect to mortgage loans comparable to the Mortgage Loans and held for its own
account. Further, the Servicer will take special care in ascertaining and
estimating on escrowed Mortgage Loans annual ground rents, taxes, assessments,
water rates, fire and hazard insurance premiums, mortgage insurance premiums,
and all other charges that, as provided in the Mortgage, will become due and
payable to that end that the installments payable by the Mortgagors will be
sufficient to pay such charges as and when they become due and payable.

                Section 3.03   Realization Upon Defaulted Mortgage Loans.

                In the event that any payment due under any Mortgage Loan is not
paid when the same becomes due and payable, or in the event the Mortgagor fails
to perform any other covenant or obligation under the Mortgage Loan and such
failure continues beyond any applicable grace period, the Servicer shall take
such action as it shall deem to be in the best interest of the
Certificateholders. With respect to any defaulted Mortgage Loan, the Servicer
shall have the right to review the status of the related forbearance plan and,
subject to the second paragraph of Section 3.01, may modify such forbearance
plan; including extending the Mortgage Loan repayment date for a period of one
year or reducing the Mortgage Interest Rate up to 50 basis points.

                In connection with a foreclosure or other conversion, the
Servicer shall exercise such rights and powers vested in it hereunder and use
the same degree of care and skill in its exercise as prudent mortgage servicers
would exercise or use under the circumstances in the conduct of their own
affairs and consistent with Applicable Regulations and the Servicing Standards,
including, without limitation, advancing funds for the payment of taxes and
insurance premiums.

                Notwithstanding the foregoing provisions of this Section 3.03,
with respect to any Mortgage Loan as to which the Servicer has received actual
notice of, or has actual knowledge of, the presence of any toxic or hazardous
substance on the related Mortgaged Property, the Servicer shall not either (i)
obtain title to such Mortgaged Property as a result of or in lieu of foreclosure
or otherwise, or (ii) otherwise acquire possession of, or take any other action
with respect to, such Mortgaged Property if, as a result of any such action, the
Trust would be considered to hold title to, to be a mortgagee-in-possession of,
or to be an owner or operator of such Mortgaged Property within the meaning of
the Comprehensive Environmental Response, Compensation and Liability Act of
1980, as amended from time to time, or any comparable law, unless the Servicer
has received the prior written consent of the NIMS Insurer and has received a
prudent report prepared by a Person who regularly conducts environmental audits
using customary industry standards, that:

                A. such Mortgaged Property is in compliance with applicable
environmental laws or, if not, that it would be in the best economic interest of
the Certificateholders to take such actions as are necessary to bring the
Mortgaged Property into compliance therewith; and

                B. there are no circumstances present at such Mortgaged Property
relating to the use, management or disposal of any hazardous substances,
hazardous materials, hazardous wastes, or petroleum-based materials for which
investigation, testing, monitoring, containment, clean-up or remediation could
be required under any federal, state or local law or regulation, or that if any
such materials are present for which such action could be required, that it
would be in the best economic interest of the Certificateholders to take such
actions with respect to the affected Mortgaged Property.

                The cost of the environmental audit report contemplated by this
Section 3.03 shall be advanced by the Servicer, subject to the Servicer's right
to be reimbursed therefor from the Collection Account as provided in Section
3.05(iv).

                If the Servicer determines, as described above, that it is in
the best economic interest of the Certificateholders to take such actions as are
necessary to bring any such Mortgaged Property into compliance with applicable
environmental laws, or to take such action with respect to the containment,
clean-up or remediation of hazardous substances, hazardous materials, hazardous
wastes, or petroleum-based materials affecting any such Mortgaged Property, then
the Servicer shall take such action as it deems to be in the best economic
interest of the Certificateholders. The cost of any such compliance,
containment, clean-up or remediation shall be advanced by the Servicer, subject
to the Servicer's right to be reimbursed therefor from the Collection Account as
provided in Section 3.05.

                Section 3.04   Collection Account and Distribution Account.

                (a) The Servicer shall segregate and hold all funds collected
and received pursuant to each Mortgage Loan separate and apart from any of its
own funds and general assets and shall establish and maintain one or more
Collection Accounts. Each Collection Account shall be an Eligible Account.

                The Servicer shall deposit or cause to be deposited on a daily
basis and in no event more than one Business Day after receipt thereof in the
clearing account (which must be an Eligible Account) in which it customarily
deposits payments and collections on mortgage loans in connection with its
mortgage loan servicing activities, and shall thereafter deposit in the
Collection Account, in no event more than one Business Day after deposit of such
funds in the clearing account, and retain therein, the following payments and
collections received or made by it after the Cut-off Date, with respect to the
Initial Mortgage Loans, or the Subsequent Cut-off Date, with respect to the
Additional Group 3 Mortgage Loans (other than in respect of principal and
interest due on or before the Cut-off Date or Subsequent Cut-off Date, as
applicable):

                (i) all payments on account of principal, including Principal
        Prepayments, on the Mortgage Loans;

                (ii) all payments on account of interest on the Mortgage Loans
        adjusted to the Mortgage Interest Rate less the Servicing Fee Rate and
        any Prepayment Interest Excess;

                (iii) all Liquidation Proceeds and any Subsequent Recoveries;

                (iv) all Insurance Proceeds including amounts required to be
        deposited pursuant to Section 3.10, other than proceeds to be held in
        the Escrow Account and applied to the restoration or repair of the
        Mortgaged Property or released to the Mortgagor in accordance with the
        Servicer's normal servicing procedures, the loan documents or applicable
        law;

                (v) all Condemnation Proceeds affecting any Mortgaged Property
        which are not released to the Mortgagor in accordance with the
        Servicer's normal servicing procedures, the loan documents or applicable
        law;

                (vi) any amounts required to be deposited by the Servicer in
        connection with any REO Property pursuant to Section 3.13;

                (vii) all Prepayment Charges collected by the Servicer in
        connection with the voluntary Principal Prepayment in full of any
        Mortgage Loan, all Originator Prepayment Charge Payment Amounts paid by
        the applicable Originator and all Servicer Prepayment Charge Payment
        Amounts required to be paid by the Servicer pursuant to Section 3.01 in
        connection with any such Principal Prepayment; and

                (viii) all amounts required to be deposited by the Servicer
        pursuant to Section 2.03.

                Any interest paid on funds deposited in the Collection Account,
subject to Section 3.25, shall accrue to the benefit of the Servicer and the
Servicer shall be entitled to retain and withdraw such interest from the
Collection Account pursuant to Section 3.05(v). The foregoing requirements for
deposit from the Collection Account shall be exclusive, it being understood and
agreed that, without limiting the generality of the foregoing, payments in the
nature of late payment charges, bad check fees, prepayment charges that are not
Prepayment Charges, Originator Prepayment Charge Payment Amounts or Servicer
Prepayment Charge Payment Amounts, assumption fees and other similar fees need
not be deposited by the Servicer in the Collection Account. Amounts deposited in
the Collection Account in error may be withdrawn by the Servicer at any time.

                (b) On behalf of the Trust Fund, the Trustee shall establish and
maintain one or more accounts (such account or accounts, the "Distribution
Account"), held in trust for the benefit of the Certificateholders. On behalf of
the Trust Fund, the Servicer shall deliver to the Trustee in immediately
available funds for deposit in the Distribution Account by 1:00 p.m. New York
time on the Servicer Remittance Date, (i) that portion of the Available Funds
(calculated without regard to the references in the definition thereof to
amounts that may be deposited to the Distribution Account from a different
source as provided herein) then on deposit in the Collection Account, (ii) the
amount of all Prepayment Charges collected by the Servicer in connection with
the voluntary Principal Prepayment in full of any of the Mortgage Loans then on
deposit in the Collection Account (other than any such Prepayment Charges
received after the related Prepayment Period) and (iii) any Originator
Prepayment Charge Payment Amount or any Servicer Prepayment Charge Payment
Amount. Amounts in the Distribution Account shall be deemed to be held on behalf
of the Grantor Trust and the related REMICs in accordance with the REMIC
distributions set forth in Section 4.08. The Trustee shall be entitled to
withdraw from the Distribution Account any amounts owing to it pursuant to
Section 8.05 and Section 9.01(c) prior to the distribution of any amounts on
deposit to the Certificateholders; provided, however, the Trustee shall provide
the Depositor, the NIMS Insurer and the Servicer with a written account of such
amounts five Business Days prior to withdrawing such funds. In connection with
any failure by the Servicer to make any remittance required to be made by the
Servicer to the Trustee for deposit in the Distribution Account on the day and
by the time such remittance is required to be made under the terms of this
Section 3.04(b) (without giving effect to any grace or cure period), the
Servicer shall pay to the Trustee for the account of the Trustee interest at the
prime rate of United States money center commercial banks as published in The
Wall Street Journal on any amount not timely remitted from and including the day
such remittance was required to be made to, but not including, the day on which
such remittance was actually made.

                (c) Funds in the Collection Account and the Distribution Account
may be invested in Eligible Investments in accordance with the provisions set
forth in Section 3.25. The Servicer shall give notice to the Trustee and the
NIMS Insurer of the location of the Collection Account maintained by it when
established and prior to any change thereof. The Trustee shall give notice to
the Servicer, the NIMS Insurer and the Depositor of the location of the
Distribution Account when established and prior to any change thereof.

                (d) In the event the Servicer shall deliver to the Trustee for
deposit in the Distribution Account any amount not required to be deposited
therein, it may at any time request that the Trustee withdraw such amount from
the Distribution Account and remit to the Servicer any such amount, any
provision herein to the contrary notwithstanding. In addition, the Servicer
shall deliver to the Trustee from time to time for deposit, and the Trustee
shall so deposit, in the Distribution Account in respect of REMIC 1:

                (i) any Advances, as required pursuant to Section 4.07;

                (ii) any Stayed Funds, as soon as permitted by the federal
        bankruptcy court having jurisdiction in such matters;

                (iii) any amounts required to be delivered by the Servicer to
        the Trustee for deposit in the Distribution Account pursuant to Sections
        2.03, 3.04, 3.13, 3.15, 3.16, 3.23, 3.24, 4.07 or 10.01; and

                (iv) any amounts required to be deposited by the Servicer
        pursuant to Section 3.11 in connection with the deductible clause in any
        blanket hazard insurance policy, such deposit being made from the
        Servicer's own funds, without reimbursement therefor.

                (e) Promptly upon receipt of any Stayed Funds, whether from the
Servicer, a trustee in bankruptcy, or federal bankruptcy court or other source,
the Trustee shall notify the Servicer of such receipt and deposit such funds in
the Distribution Account, subject to withdrawal thereof as permitted hereunder.
In addition, the Trustee shall deposit in the Distribution Account any amounts
required to be deposited pursuant to Section 3.25(b) in connection with losses
realized on Eligible Investments with respect to funds held in the Distribution
Account.

                (f) Any Prepayment Charges, Originator Prepayment Charge Payment
Amounts and Servicer Prepayment Charge Payment Amounts deposited pursuant to
Section 3.04(a)(vii) shall not be assets of any REMIC created hereunder, but
shall be considered assets of the Grantor Trust held by the Trustee for the
benefit of the Class P Certificateholders.

                Section 3.05   Permitted Withdrawals From the Collection
Account.

                The Servicer may, from time to time, withdraw from the
Collection Account for the following purposes:

                (i) to remit to the Trustee for deposit in the Distribution
        Account the amounts required to be so remitted pursuant to Section
        3.04(b) or permitted to be so remitted pursuant to the first sentence of
        Section 3.04(d);

                (ii) to reimburse itself for (a) any unreimbursed Advances to
        the extent of amounts received which represent Late Collections (net of
        the related Servicing Fees) of Monthly Payments, Liquidation Proceeds
        and Insurance Proceeds on Mortgage Loans with respect to which such
        Advances were made in accordance with the provisions of Section 4.07;
        (b) any unreimbursed Advances with respect to the final liquidation of a
        Mortgage Loan that are Nonrecoverable Advances, but only to the extent
        that Late Collections, Liquidation Proceeds and Insurance Proceeds
        received with respect to such Mortgage Loan are insufficient to
        reimburse the Servicer for such unreimbursed Advances; or (c) subject to
        Section 4.07(b), any unreimbursed Advances to the extent of funds held
        in the Collection Account for future distribution that were not included
        in Available Funds for the preceding Distribution Date;

                (iii) to reimburse itself for (a) any unpaid Servicing Fees, (b)
        any unreimbursed Servicing Advances with respect to each Mortgage Loan,
        but only to the extent of any Late Collections, Liquidation Proceeds,
        Insurance Proceeds and condemnation proceeds received with respect to
        such Mortgage Loan, and (c) any Servicing Advances with respect to the
        final liquidation of a Mortgage Loan that are Nonrecoverable Advances,
        but only to the extent that Late Collections, Liquidation Proceeds and
        Insurance Proceeds received with respect to such Mortgage Loan are
        insufficient to reimburse the Servicer for Servicing Advances;

                (iv) to reimburse itself for any amounts paid or expenses
        incurred pursuant to Section 3.03 (and not otherwise previously
        reimbursed);

                (v) to pay to itself as servicing compensation (a) any interest
        earned on funds in the Collection Account (all such interest to be
        withdrawn monthly not later than each Servicer Remittance Date), (b) the
        Servicing Fee from that portion of any payment or recovery as to
        interest to a particular Mortgage Loan to the extent not retained
        pursuant to Section 3.04(a)(ii) and (c) any Prepayment Interest Excess;

                (vi) to pay or reimburse itself for any amounts payable or paid
        pursuant to Section 6.03 (and not otherwise previously reimbursed); and

                (vii) to clear and terminate the Collection Account upon the
        termination of this Agreement.

                The foregoing requirements for withdrawal from the Collection
Account shall be exclusive. In the event the Servicer shall deposit in the
Collection Account any amount not required to be deposited therein, it may at
any time withdraw such amount from the Collection Account, any provision herein
to the contrary notwithstanding.

                Section 3.06   Establishment of Escrow Accounts; Deposits in
Escrow Accounts.

                The Servicer shall segregate and hold all funds collected and
received pursuant to each Mortgage Loan which constitute Escrow Payments
separate and apart from any of its own funds and general assets and shall
establish and maintain one or more Escrow Accounts (which may be evidenced by a
letter agreement), in the form of time deposit or demand accounts. A copy of
such letter agreement shall be furnished to the Trustee upon request. The Escrow
Account shall be an Eligible Account.

                The Servicer shall deposit or cause to be deposited on a daily
basis and in no event more than one Business Day after receipt thereof in the
clearing account (which must be an Eligible Account) in which it customarily
deposits payments and collections on mortgage loans in connection with its
mortgage loan servicing activities, and shall thereafter deposit in the Escrow
Account or Accounts, in no event more than one Business Day after deposit of
such funds in the clearing account, and retain therein, (i) all Escrow Payments
collected on account of the Mortgage Loans, for the purpose of effecting timely
payment of any such items as required under the terms of this Agreement, and
(ii) all Insurance Proceeds which are to be applied to the restoration or repair
of any Mortgaged Property. The Servicer shall make withdrawals therefrom only to
effect such payments as are required under this Agreement, and for such other
purposes as shall be set forth in, or in accordance with, Section 3.07. The
Servicer shall be entitled to retain any interest paid on funds deposited in the
Escrow Account by the depository institution other than interest on escrowed
funds required by law to be paid to the Mortgagor and, to the extent required by
the related Mortgage Loan or Applicable Regulations, the Servicer shall pay
interest on escrowed funds to the Mortgagor notwithstanding that the Escrow
Account is non-interest bearing or that interest paid thereon is insufficient
for such purposes.

                Section 3.07   Permitted Withdrawals From Escrow Account.

                Withdrawals from the Escrow Account may be made by the Servicer
(i) to effect timely payments of ground rents, taxes, assessments, water rates,
fire, flood and hazard insurance premiums and comparable items in a manner and
at a time that assures that the lien priority of the Mortgage is not jeopardized
(or, with respect to the payment of taxes, in a manner and at a time that avoids
the loss of the Mortgaged Property due to a tax sale or the foreclosure as a
result of a tax lien), (ii) to reimburse the Servicer for any Servicing Advance
made by the Servicer with respect to a related Mortgage Loan but only from
amounts received on the related Mortgage Loan which represent late payments or
Late Collections of Escrow Payments thereunder with respect to taxes and
assessments and with respect to hazard insurance, (iii) to refund to the
Mortgagor any funds as may be determined to be overages, (iv) for transfer to
the Collection Account in accordance with the terms of this Agreement, (v) for
application to restoration or repair of the Mortgaged Property, (vi) to pay to
the Servicer, or to the Mortgagor to the extent required by the related Mortgage
Loan or Applicable Regulations, any interest paid on the funds deposited in the
Escrow Account, (vii) to clear and terminate the Escrow Account on the
termination of this Agreement, or (viii) to transfer to the Collection Account
any insurance proceeds. As part of its servicing duties, the Servicer shall pay
to the Mortgagor interest on funds in the Escrow Account, to the extent required
by the related Mortgage Loan or Applicable Regulations, and to the extent that
interest earned on funds in the Escrow Account is insufficient, shall pay such
interest from its own funds, without any reimbursement therefor.

                In the event the Servicer shall deposit in the Escrow Account
any amount not required to be deposited therein, it may at any time withdraw
such amount from the Escrow Account, any provision herein to the contrary
notwithstanding.

                Section 3.08   Payment of Taxes, Insurance and Other Charges;
Collections Thereunder.

                With respect to each Mortgage Loan that provides for Escrow
Payments, the Servicer shall maintain accurate records reflecting the status of
ground rents, taxes, assessments, water rates and other charges which are or may
become a lien upon the Mortgaged Property and the status of fire, flood and
hazard insurance coverage and shall obtain, from time to time, all bills for the
payment of such charges (including renewal premiums) and shall effect payment of
taxes, assessments, hazard insurance premiums, and comparable items in a manner
and at a time that assures that the lien priority of the Mortgage is not
jeopardized (or, with respect to the payment of taxes, in a manner and at a time
that avoids the loss of the Mortgaged Property due to a tax sale or the
foreclosure as a result of a tax lien). To the extent that the Mortgage does not
provide for Escrow Payments, the Servicer shall use its best efforts to
determine that any such payments are made by the Mortgagor at the time they
first become due. If any such payment has not been made, the Servicer will
advance or cause to be advanced funds necessary to avoid the lapse of insurance
coverage on the Mortgaged Property and to assure that no Mortgaged Property is
lost to a tax sale or foreclosure as a result of a tax lien.

                Section 3.09   Transfer of Accounts.

                The Servicer may transfer the Collection Account and the Escrow
Account to a different depository institution from time to time. Upon such
transfer, the Servicer shall deliver to the Trustee, the NIMS Insurer and the
Depositor, a certification or letter agreement, as the case may be, as required
pursuant to Sections 3.04 and 3.06.

                Section 3.10   Maintenance of Hazard Insurance.

                The Servicer shall cause to be maintained for each Mortgage Loan
fire and hazard insurance with extended coverage as is customary in the area
where the Mortgaged Property is located in an amount which is at least equal to
the lesser of (i) the amount necessary to fully compensate for any damage or
loss to the improvements which are a part of such property on a replacement cost
basis or (ii) the Principal Balance of the Mortgage Loan, in each case in an
amount not less than such amount as is necessary to prevent the Mortgagor and/or
the Mortgagee from becoming a co-insurer. If the Mortgaged Property is in an
area identified in the Federal Register by the Flood Emergency Management Agency
as having special flood hazards and flood insurance has been made available, the
Servicer will cause to be maintained a flood insurance policy meeting the
requirements of the current guidelines of the Federal Insurance Administration
with a generally acceptable insurance carrier, in an amount representing
coverage not less than the least of (i) the Principal Balance of the Mortgage
Loan, (ii) the maximum insurable value of the improvements securing such
Mortgage Loan or (iii) the maximum amount of insurance which is available under
the National Flood Insurance Act of 1968, as amended. The Servicer shall also
maintain on the REO Property for the benefit of the Certificateholders, (x) fire
and hazard insurance with extended coverage in an amount which is at least equal
to the lesser of (i) 100% of the maximum insurable value of the improvements
securing the Mortgage Loan and (ii) the outstanding Principal Balance of the
Mortgage Loan at the time it became an REO Property, (y) public liability
insurance and, (z) to the extent required and available under the National Flood
Insurance Act of 1968, as amended, flood insurance in an amount as provided
above. Any amounts collected by the Servicer under any such policies other than
amounts to be deposited in the Escrow Account and applied to the restoration or
repair of the Mortgaged Property or REO Property, or released to the Mortgagor
in accordance with the Servicer's normal servicing procedures, shall be
deposited in the Collection Account, subject to withdrawal pursuant to Section
3.05. It is understood and agreed that no earthquake or other additional
insurance is required to be maintained by the Servicer or the Mortgagor or
maintained on property acquired in respect of the Mortgage Loan, other than
pursuant to such Applicable Regulations as shall at any time be in force and as
shall require such additional insurance. All such policies shall be endorsed
with standard mortgagee clauses with loss payable to the Servicer and shall
provide for at least thirty days prior written notice of any cancellation,
reduction in the amount of or material change in coverage to the Servicer. The
Servicer shall not interfere with the Mortgagor's freedom of choice in selecting
either his insurance carrier or agent, provided, however, that the Servicer
shall not accept any such insurance policies from insurance companies unless
such companies currently reflect a general policy rating of B:III or better in
Best's Key Rating Guide and are licensed to do business in the state wherein the
property subject to the policy is located.

                Section 3.11   Maintenance of Mortgage Impairment Insurance
Policy.

                In the event that the Servicer shall obtain and maintain a
blanket policy issued by an insurer that has a general policy rating of B:III or
better in Best's Key Rating Guide insuring against hazard losses on all of the
Mortgage Loans, then, to the extent such policy provides coverage in an amount
equal to the amount required pursuant to Section 3.10 and otherwise complies
with all other requirements of Section 3.10, it shall conclusively be deemed to
have satisfied its obligations as set forth in Section 3.10, it being understood
and agreed that such policy may contain a deductible clause, in which case the
Servicer shall, in the event that there shall not have been maintained on the
related Mortgaged Property or REO Property a policy complying with Section 3.10,
and there shall have been a loss which would have been covered by such policy,
deliver to the Trustee for deposit in the Distribution Account the amount not
otherwise payable under the blanket policy because of such deductible clause,
which amount shall not be reimbursable to the Servicer from the Trust Fund. In
connection with its activities as servicer of the Mortgage Loans, the Servicer
agrees to prepare and present, on behalf of the Trustee, claims under any such
blanket policy in a timely fashion in accordance with the terms of such policy.
Upon request of the Trustee, the Servicer shall cause to be delivered to the
Trustee a certified true copy of such policy and a statement from the insurer
thereunder that such policy shall in no event be terminated or materially
modified without thirty days prior written notice to the Trustee.

                Section 3.12   Fidelity Bond, Errors and Omissions Insurance.

                The Servicer shall maintain, at its own expense, a blanket
fidelity bond (the "Fidelity Bond") and an errors and omissions insurance
policy, with broad coverage with financially responsible companies on all
officers, employees or other persons acting in any capacity with regard to the
Mortgage Loans to handle funds, money, documents and papers relating to the
Mortgage Loans. The Fidelity Bond and errors and omissions insurance shall be in
the form of the Mortgage Banker's Blanket Bond and shall protect and insure the
Servicer against losses, including forgery, theft, embezzlement, fraud, errors
and omissions and negligent acts of such persons. Such Fidelity Bond shall also
protect and insure the Servicer against losses in connection with the failure to
maintain any insurance policies required pursuant to this Agreement and the
release or satisfaction of a Mortgage Loan without having obtained payment in
full of the indebtedness secured thereby. No provision of this Section 3.12
requiring the Fidelity Bond and errors and omissions insurance shall diminish or
relieve the Servicer from its duties and obligations as set forth in this
Agreement. The minimum coverage under any such bond and insurance policy shall
be at least equal to the corresponding amounts required by Fannie Mae in the
Fannie Mae MBS Selling and Servicing Guide or by Freddie Mac in the Freddie Mac
Servicer's Guide. Upon request of the Trustee or the NIMS Insurer, the Servicer
shall cause to be delivered to the requesting party a certified true copy of the
Fidelity Bond and errors and omissions insurance policy and a statement from the
surety and the insurer that such Fidelity Bond and errors and omissions
insurance policy shall in no event be terminated or materially modified without
thirty days' prior written notice to the Trustee.

                Section 3.13   Title, Management and Disposition of REO
Property.

                (a) In the event that title to a Mortgaged Property is acquired
in foreclosure or by deed in lieu of foreclosure, the deed or certificate of
sale shall be taken (pursuant to a limited power of attorney to be provided by
the Trustee to the Servicer) in the name of the Trustee or its nominee, on
behalf of the Certificateholders, or in the event the Trustee is not authorized
or permitted to hold title to real property in the state where the REO Property
is located, or would be adversely affected under the "doing business" or tax
laws of such state by so holding title, the deed or certificate of sale shall be
taken in the name of such Person or Persons as shall be consistent with an
Opinion of Counsel obtained by the Servicer from an attorney duly licensed to
practice law in the state where the REO Property is located. Any Person or
Persons holding such title other than the Trustee shall acknowledge in writing
that such title is being held as nominee for the benefit of the Trustee.

                (b) In the event that the Trust Fund acquires any REO Property
as aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Servicer shall dispose of such REO Property before the end of
the third taxable year beginning after the year of its acquisition by the Trust
Fund for purposes of Section 860G(a)(8) of the Code unless the Servicer has
received a grant of extension from the Internal Revenue Service of the
above-mentioned grace period such that the holding by the Trust Fund of such REO
Property subsequent to such period will not: (i) result in the imposition of any
tax on "prohibited transactions" as defined in Section 860F of the Code; or (ii)
cause any REMIC constituting any part of the Trust Fund to fail to qualify as a
REMIC at any time that any Certificates (other than the Class P Certificates)
are outstanding, in which case the Trust Fund may continue to hold such REO
Property.

                Subject to compliance with applicable laws and regulations as
shall at any time be in force, and notwithstanding any other provisions of this
Agreement, no REO Property acquired by the Trust Fund shall be rented (or
allowed to continue to be rented) or otherwise used by or on behalf of the Trust
Fund in such a manner or pursuant to any terms that would: (i) cause such REO
Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code; or (ii) subject any REMIC constituting part of
the Trust Fund to the imposition of any federal income taxes on the income
earned from such REO Property, including any taxes imposed by reason of Sections
860F or 860G(c) of the Code, unless the Servicer has agreed to indemnify and
hold harmless the Trust Fund with respect to the imposition of any such taxes.

                The Servicer shall manage, conserve, protect and operate each
REO Property for the Certificateholders and the Trust Fund solely for the
purpose of its prompt disposition and sale in a manner which does not cause such
REO Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code or result in the receipt by the related REMIC of
any "income from non-permitted assets" within the meaning of Section
860F(a)(2)(B) of the Code, or any "net income from foreclosure property" which
is subject to taxation under the REMIC Provisions. The Servicer shall cause each
REO Property to be inspected promptly upon the acquisition of title thereto and
shall cause each REO Property to be inspected at least annually thereafter. The
Servicer shall make or cause to be made a written or electronic report of each
such inspection. Such reports shall be retained in the Mortgage File and copies
thereof shall be forwarded by the Servicer to the Trustee upon request. The
Servicer shall attempt to sell the same (and may temporarily rent the same) on
such terms and conditions as the Servicer deems to be in the best interest of
the Certificateholders and the Trust Fund.

                With respect to each REO Property, the Servicer shall account
separately for each REO Property with respect to all funds collected and
received in connection with the operation of such REO Property.

                The Servicer shall deposit or cause to be deposited, on a daily
basis, within one Business Day of receipt, in the Collection Account, all
revenues received with respect to each REO Property and shall withdraw therefrom
funds necessary for the proper operation, management and maintenance of the
related REO Property, including the cost of maintaining any hazard insurance
pursuant to Section 3.10 hereof and the fees of any managing agent acting on
behalf of the Servicer.

                The Servicer shall furnish to the Trustee, on each Servicer
Remittance Date, an operating statement for each REO Property covering the
operation of each REO Property for the previous month. Such operating statement
shall be accompanied by such other information as the Trustee shall reasonably
request.

                The Servicer shall use its best efforts to dispose of the REO
Property as promptly as is practically consistent with protecting the
Certificateholders' interests.

                Each REO Disposition shall be carried out by the Servicer at
such price and upon such terms and conditions as the Servicer deems to be in the
best interest of the Certificateholders. If as of the date title to any REO
Property was acquired by the Servicer there were outstanding unreimbursed
Servicing Advances, Servicing Fees and Advances with respect to the REO
Property, the Servicer, upon an REO Disposition of such REO Property, shall be
entitled to reimbursement for any related unreimbursed Servicing Advances,
Servicing Fees and Advances from proceeds received in connection with such REO
Disposition. The proceeds from the REO Disposition, net of any payment to the
Servicer as provided above, shall be deposited in the Collection Account for
transfer to the Distribution Account on the succeeding Servicer Remittance Date
in accordance with Section 3.04(a)(vi).

                Any REO Disposition shall be for cash only (unless changes in
the REMIC Provisions made subsequent to the Startup Day allow a sale for other
consideration and an Opinion of Counsel is obtained by the Servicer to the
effect that such sale shall not cause any REMIC constituting part of the Trust
Fund to fail to qualify as a REMIC).

                Section 3.14   Due-on-Sale Clauses; Assumption and Substitution
Agreements.

                When a Mortgaged Property has been or is about to be conveyed by
the Mortgagor, the Servicer shall, to the extent it has knowledge of such
conveyance or prospective conveyance, exercise its rights to accelerate the
maturity of the related Mortgage Loan under any "due-on-sale" clause contained
in the related Mortgage or Mortgage Note; provided, however, that the Servicer
shall not exercise any such right if the "due-on-sale" clause, in the reasonable
belief of the Servicer, is not enforceable under applicable law. In such event,
the Servicer shall make reasonable efforts to enter into an assumption and
modification agreement with the Person to whom such property has been or is
about to be conveyed, pursuant to which such Person becomes liable under the
Mortgage Note and, unless prohibited by applicable law or the Mortgage, the
Mortgagor remains liable thereon. If the foregoing is not permitted under
applicable law, the Servicer is authorized to enter into a substitution of
liability agreement with such Person, pursuant to which the original Mortgagor
is released from liability and such Person is substituted as Mortgagor and
becomes liable under the Note; provided that no such substitution will be
permitted unless such person satisfies the underwriting criteria of the Servicer
and has a credit score at least equal to that of the original Mortgagor. The
Mortgage Loan, as assumed, shall conform in all respects to the requirements,
representations and warranties of this Agreement. The Servicer shall not take or
enter into any assumption and modification agreement, however, unless (to the
extent practicable under the circumstances) it shall have received confirmation,
in writing, of the continued effectiveness of any applicable hazard insurance
policy. The Servicer shall notify the Trustee that any such assumption or
substitution agreement has been completed by forwarding to the Trustee the
original copy of such assumption or substitution agreement (indicating the
Mortgage File to which it relates) which copy shall be added by the Trustee to
the related Mortgage File and which shall, for all purposes, be considered a
part of such Mortgage File to the same extent as all other documents and
instruments constituting a part thereof. The Servicer shall be responsible for
recording any such assumption or substitution agreements. In connection with any
such assumption or substitution agreement, the Monthly Payment on the related
Mortgage Loan shall not be changed but shall remain as in effect immediately
prior to the assumption or substitution, the stated maturity or outstanding
principal amount of such Mortgage Loan shall not be changed nor shall any
required monthly payments of principal or interest be deferred or forgiven. Any
fee collected by the Servicer for consenting to any such conveyance or entering
into an assumption or substitution agreement shall be retained by or paid to the
Servicer as additional servicing compensation.

                Notwithstanding the foregoing paragraph or any other provision
of this Agreement, the Servicer shall not be deemed to be in default, breach or
any other violation of its obligations hereunder by reason of any assumption of
a Mortgage Loan by operation of law or any assumption which the Servicer may be
restricted by law from preventing, for any reason whatsoever.

                Section 3.15   Notification of Adjustments.

                On each Adjustment Date, the Servicer shall make Mortgage
Interest Rate adjustments for each Adjustable-Rate Mortgage Loan in compliance
with the requirements of the related Mortgage and Mortgage Note and Applicable
Regulations. The Servicer shall execute and deliver the notices required by each
Mortgage and Mortgage Note and Applicable Regulations regarding Mortgage
Interest Rate adjustments. Upon the discovery by the Servicer or the Trustee
that the Servicer has failed to adjust or has incorrectly adjusted a Mortgage
Interest Rate or a Monthly Payment pursuant to the terms of the related Mortgage
Note and Mortgage, the Servicer shall deliver to the Trustee for deposit in the
Distribution Account from its own funds the amount of any interest loss caused
thereby without reimbursement therefor; provided, however, the Servicer shall be
held harmless with respect to any Mortgage Interest Rate adjustments made by any
servicer prior to the Servicer.

                Section 3.16   Subservicing; Enforcement of the Obligations of
the Servicer

                The Servicer shall not hire or otherwise utilize the services of
any Subservicer to fulfill any of the obligations of the Servicer as servicer
under this Agreement unless the Servicer complies with the provisions of this
Section 3.16 and the proposed Subservicer (i) is an institution which is an
approved Fannie Mae or Freddie Mac Seller/Servicer as indicated in writing, (ii)
represents and warrants that it is in compliance with the laws of each state as
necessary to enable it to perform its obligations under such subservicing
agreement and (iii) is acceptable to the NIMS Insurer.

                The Servicer shall give prior written notice to the Trustee, the
Depositor and the NIMS Insurer of the appointment of any Subservicer and shall
furnish to the Trustee, the Depositor and the NIMS Insurer a copy of any related
subservicing agreement. For purposes of this Agreement, the Servicer shall be
deemed to have received payments on Mortgage Loans immediately upon receipt by
any Subservicer of such payments. Any such subservicing agreement shall be
consistent with and not violate the provisions of this Agreement. Each
subservicing agreement shall provide that a successor Servicer or the Trustee
shall have the option to terminate such agreement without payment of any fees if
the predecessor Servicer is terminated or resigns. The Servicer shall cause any
Subservicer used by the Servicer (or by any Subservicer) to comply with the
provisions of this Section 3.16 and with Sections 3.19, 3.20 and 3.31 of this
Agreement (and shall amend, with the consent of the parties hereto, Exhibit Q to
reflect such Subservicer's Assessment of Compliance with the Servicing Criteria)
to the same extent as if such Subservicer were the Servicer. The Servicer shall
be responsible for obtaining from each such Subservicer and delivering to the
applicable Persons any Assessment of Compliance and related Attestation Report
required to be delivered by such Subservicer under Sections 3.19 and 3.20 and
any certification required to be delivered under Section 3.31 to the Person that
will be responsible for signing the Sarbanes-Oxley Certification, in each case
as and when required to be delivered.

                Subject to the conditions set forth in this Section 3.16, the
Servicer is permitted to utilize one or more Subcontractors to perform certain
of its obligations hereunder. The Servicer shall promptly upon request provide
to the Depositor a written description (in form and substance satisfactory to
the Depositor) of the role and function of each Subcontractor utilized by the
Servicer, specifying (i) the identity of each such Subcontractor that is a
Servicing Function Participant and (ii) which elements of the Servicing Criteria
will be addressed in Assessments of Compliance provided by each Servicing
Function Participant. As a condition to the utilization by the Servicer of any
Servicing Function Participant, the Servicer shall cause any such Servicing
Function Participant for the benefit of the Depositor to comply with the
provisions of Section 3.19 and 3.20 of this Agreement to the same extent as if
such Servicing Function Participant were the Servicer. The Servicer shall be
responsible for obtaining from each such Servicing Function Participant and
delivering to the applicable Persons any Assessment of Compliance and related
Attestation Report required to be delivered by such Servicing Function
Participant under Section 3.20, in each case as and when required to be
delivered.

                Notwithstanding the foregoing, if the Servicer engages a
Subcontractor in connection with the performance of any of its duties under this
Agreement, the Servicer shall be responsible for determining whether such
Subcontractor is an Additional Servicer.

                Notwithstanding any subservicing agreement or the provisions of
this Agreement relating to agreements or arrangements between the Servicer and a
Subservicer or a Subcontractor or reference to actions taken through a
Subservicer, Subcontractor or otherwise, the Servicer shall remain obligated and
primarily liable to the Trustee and the Certificateholders for the servicing and
administering of the Mortgage Loans in accordance with the provisions of Section
3.01 without diminution of such obligation or liability by virtue of such
subservicing agreements or arrangements or by virtue of indemnification from the
Subservicer or the Subcontractor and to the same extent and under the same terms
and conditions as if the Servicer alone were servicing and administering the
Mortgage Loans. The Servicer shall be entitled to enter into any agreement with
a Subservicer or Subcontractor for indemnification of the Servicer by such
Subservicer or Subcontractor and nothing contained in this Agreement shall be
deemed to limit or modify such indemnification.

                The Servicer shall indemnify the Depositor, the Sponsor and the
Trustee and any of their directors, officers, employees or agents and hold them
harmless against any and all claims, losses, damages, penalties, fines,
forfeitures, reasonable and necessary legal fees and related costs, judgments,
and any other costs, fees and expenses that any of them may sustain in any way
related to the failure of the Servicer to perform any of its obligations under
Section 3.16, Section 3.19, Section 3.20 or Section 3.31.

                Section 3.17   Trustee to Cooperate; Release of Files.

                (a) Upon the payment in full of any Mortgage Loan (including any
liquidation of such Mortgage Loan through foreclosure or otherwise, or the
receipt by the Servicer of a notification that payment in full will be escrowed
in a manner customary for such purposes), the Servicer shall deliver to the
Trustee, in written form (with two executed copies) or electronic form, of a
completed "Request for Release" in the form of Exhibit E. Upon receipt of such
Request for Release of Documents, the Trustee shall promptly release the related
Mortgage File within three (3) Business Days via overnight mail delivery (at the
expense of the Servicer), in trust, to (i) the Servicer, or (ii) such other
party identified in the related Request for Release. The Trustee agrees to
indemnify the Servicer, out of its own funds, for any loss, liability or expense
(other than special, indirect, punitive or consequential damages which will not
be paid by the Trustee) incurred by the Servicer as a direct result of the
negligence or willful misconduct by the Trustee in releasing the Mortgage File
as provided above. Upon any such payment in full, or the receipt of such
notification that such funds have been placed in escrow, the Trustee hereby
authorizes and empowers the Servicer to execute an instrument of satisfaction
(or assignment of Mortgage without recourse) regarding the Mortgaged Property
relating to such Mortgage, which instrument of satisfaction or assignment shall
be delivered to the Person or Persons entitled thereto against receipt therefor
of payment in full, it being understood and agreed that no expense incurred in
connection with such instrument of satisfaction or assignment, as the case may
be, shall be chargeable to the Collection Account.

                (b) From time to time and as appropriate in the servicing of any
Mortgage Loan, including, without limitation, foreclosure or other comparable
conversion of a Mortgage Loan or collection under any insurance policy relating
to a Mortgage Loan, the Trustee shall (except in the case of the payment or
liquidation pursuant to which the related Mortgage File is released to an escrow
agent or an employee, agent or attorney of the Trustee), upon written request of
the Servicer and delivery to the Trustee, in written form (with two executed
copies) or electronic form, of a "Request for Release" in the form of Exhibit E
signed by a Servicing Officer, release the related Mortgage File to the Servicer
within three (3) Business Days and shall execute such documents as shall be
necessary to the prosecution of any such proceedings, including, without
limitation, an assignment without recourse of the related Mortgage to the
Servicer. Such receipt shall obligate the Servicer to return the Mortgage File
to the Trustee when the need therefor by the Servicer no longer exists unless
the Mortgage Loan shall be liquidated, in which case, upon receipt of a Request
for Release evidencing such liquidation, the receipt shall be released by the
Trustee to the Servicer.

                (c) Subject to Section 3.01, the Servicer shall have the right
to accept applications of Mortgagors for consent to (i) partial releases of
Mortgages, (ii) alterations, (iii) removal, demolition or division of properties
subject to Mortgages, (iv) modifications, and (v) second mortgage subordination
agreements. No application for approval shall be considered by the Servicer
unless: (w) it has received an Opinion of Counsel, addressed to the Trustee
(which opinion shall not be an expense of the Trustee or the Trust Fund) that
such sale, disposition, substitution, acquisition or contribution will not
affect adversely the status of any REMIC constituting part of the Trust Fund as
a REMIC or cause any REMIC constituting part of the Trust Fund to be subject to
a tax on "prohibited transactions" or "contributions" pursuant to the REMIC
Provisions; (x) the provisions of the related Note and Mortgage have been
complied with; (y) the Combined Loan-to-Value Ratio and debt-to-income ratio
after any release does not exceed the maximum Combined Loan-to-Value Ratio and
debt-to-income ratio established in accordance with the underwriting standards
of the Mortgage Loans; and (z) the lien priority of the related Mortgage is not
affected. Upon receipt by the Trustee of a Servicing Officer's certificate
setting forth the action proposed to be taken in respect of a particular
Mortgage Loan and certifying that the criteria set forth in the immediately
preceding sentence have been satisfied, the Trustee shall execute and deliver to
the Servicer the consent or partial release so requested by the Servicer. A
proposed form of consent or partial release, as the case may be, shall accompany
any Servicing Officer's certificate delivered by the Servicer pursuant to this
paragraph.

                Section 3.18   Servicing Compensation.

                As compensation for its activities hereunder, the Servicer shall
be entitled to retain the amount of the Servicing Fee with respect to each
Mortgage Loan (including REO Properties) and any Prepayment Interest Excess. The
Servicer shall be entitled to retain additional servicing compensation in the
form of release fees, bad check charges, assumption fees, modification or
extension fees, late payment charges, prepayment charges that are not Prepayment
Charges, Originator Prepayment Charge Payment Amounts or Servicer Prepayment
Charge Payment Amounts, or any other service-related fees and similar items, to
the extent collected from Mortgagors.

                Section 3.19   Annual Statement as to Compliance.

                The Trustee and the Servicer shall deliver, and shall cause each
Additional Servicer engaged by it to deliver, or otherwise make available to the
Depositor, the NIMS Insurer, the Trustee and each Rating Agency, no later than
March 15th of each calendar year beginning in 2007, an officers' certificate in
the form required by Item 1123 of Regulation AB (each, a "Compliance
Statement"), signed by an officer of such party, stating, as to the signer
thereof, that (a) a review of the activities of such party during the preceding
calendar year or portion thereof and of the performance of such party under this
Agreement, or, in the case of an Additional Servicer, such other applicable
agreement, has been made by such officer or under such officer's supervision
and (b) to the best of such officers' knowledge, based on such review, such
party has fulfilled all of its obligations under this Agreement, or, in the case
of an Additional Servicer, such other applicable agreement in all material
respects throughout such year or portion thereof, or, if there has been a
failure to fulfill any such obligation in any material respect, specifying each
such failure known to such officer and the nature and status thereof. Each such
Compliance Statement shall contain no restrictions or limitations on its use.
The obligations of the Servicer and the Trustee under this Section apply to each
entity that acted as Servicer or Trustee, as applicable, during the applicable
period, whether or not such entity is acting as Servicer or Trustee at the time
such Compliance Statement is required to be delivered.

                Section 3.20   Assessments of Compliance; Attestation Reports.

                (a) Each of the Servicer and the Trustee, at its own expense,
shall furnish, and shall cause any Servicing Function Participant engaged by it
to furnish, at such party's expense, to the Trustee, the NIMS Insurer and the
Depositor in electronic form, on or before March 15th of each calendar year
beginning in 2007, a report on an assessment of compliance (each, an "Assessment
of Compliance") with the Servicing Criteria applicable to it that contains (A) a
statement by such party of its responsibility for assessing compliance with the
Servicing Criteria applicable to it, (B) a statement that such party used the
Servicing Criteria to assess compliance with the Servicing Criteria applicable
to it, (C) such party's assessment of compliance with the Servicing Criteria
applicable to it as of and for the fiscal year covered by the Form 10-K required
to be filed pursuant to Section 3.31, including, if there has been any material
instance of noncompliance with the Servicing Criteria applicable to it, an
identification of each such failure and the nature and status thereof, (D) a
statement that a registered public accounting firm has issued an Attestation
Report on such party's Assessment of Compliance with the Servicing Criteria
applicable to such party as of and for such period and (E) a statement as to
which of the Servicing Criteria, if any, are not applicable to such party, which
statement shall be based on the activities it performs with respect to
asset-backed securities transactions taken as a whole involving such party, that
are backed by the same asset type as the Mortgage Loans.

                Each such Assessment of Compliance shall be addressed to the
Depositor and the Trustee and signed by an authorized officer of the applicable
party, and shall address each of the Relevant Servicing Criteria set forth on
Exhibit Q hereto, or as set forth in the notification furnished to the Depositor
and the Trustee pursuant to Section 3.20(c). The Servicer and the Trustee hereby
acknowledge and agree that their respective Assessments of Compliance will cover
the items identified on Exhibit Q hereto as being covered by such party. The
parties to this Agreement acknowledge that where a particular Servicing
Criterion has multiple components, each party's assessment of compliance (and
related Attestation of Compliance) will relate only to those components that are
applicable to such party. Promptly after receipt of such Assessments of
Compliance, the Trustee shall confirm that the Assessments of Compliance, taken
individually address the applicable Servicing Criteria for each party as set
forth on Exhibit Q and notify the Depositor of any exceptions.

                (b) Each of the Servicer and the Trustee, at its own expense,
shall cause, and shall cause any Servicing Function Participant engaged by it,
at such party's expense, to cause, on or before March 15th of each year,
commencing in 2007, a registered public accounting firm (which may also render
other services to the Servicer, the Trustee, or such other Servicing Function
Participants, as the case may be) and that is a member of the American Institute
of Certified Public Accountants to furnish electronically a report (an
"Attestation Report") to the Trustee and the Depositor (with a hard copy to
follow within 10 calendar days), to the effect that (i) it has obtained a
representation regarding certain matters from the management of such party,
which includes an assertion that such party has complied with the Servicing
Criteria applicable to it, and (ii) on the basis of an examination conducted by
such firm in accordance with standards for attestation engagements issued or
adopted by the Public Company Accounting Oversight Board, it is expressing an
opinion as to whether such party's Assessment of Compliance with the Servicing
Criteria was fairly stated in all material respects, or it cannot express an
overall opinion regarding such party's Assessment of Compliance with the
Servicing Criteria. In the event that an overall opinion cannot be expressed,
such registered public accounting firm shall state in such report why it was
unable to express such an opinion. Such report must be available for general use
and not contain restricted use language. If requested by the Depositor, such
report shall contain or be accompanied by a consent of such accounting firm to
inclusion or incorporation of such report in the Depositor's registration
statement on Form S-3 relating to the Offered Certificates and the Form 10-K for
the Trust.

                Promptly after receipt of such Assessment of Compliance and
Attestation Report, the Trustee shall confirm that each Assessment of Compliance
is coupled with a related Attestation Report and shall notify the Depositor of
any exceptions.

                (c) No later than 30 days following the end of each fiscal year
for the Trust for which a Form 10-K is required to be filed, (i) the Servicer
shall forward to the Trustee and Depositor the name of each Servicing Function
Participant engaged by it and what Servicing Criteria will be addressed in the
report on Assessment of Compliance prepared by such Servicing Function
Participant and (ii) the Trustee shall forward to the Depositor the name of each
Servicing Function Participant engaged by it and what Servicing Criteria will be
addressed in the report on Assessment of Compliance prepared by such Servicing
Function Participant, in each case to the extent of any change from the prior
year's notice, if any. When the Servicer and the Trustee submit their respective
Assessment of Compliance to the Depositor, the Servicer and/or Trustee, as
applicable, shall also at such time include the Assessment of Compliance and
Attestation Report of each Servicing Function Participant engaged by the
Servicer and/or Trustee, as applicable.

                (d) Beginning with fiscal year 2008 and thereafter, none of the
Servicer, the Trustee or any Servicing Function Participant engaged by such
parties shall be required to deliver or cause the delivery of any such
Assessments of Compliance or Attestation Reports until April 15 unless such
party has received written notice from the Depositor that a Form 10-K is
required to be filed in respect of the Trust for the preceding fiscal year.

                Section 3.21   Access to Certain Documentation and Information
Regarding the Mortgage Loans.

                (a) The Servicer shall provide to the Trustee,
Certificateholders that are federally insured savings and loan associations, the
Office of Thrift Supervision, the FDIC and the supervisory agents and examiners
of each of the foregoing (which, in the case of supervisory agents and
examiners, may be required by applicable state and federal regulations) access
to the available documentation regarding the Mortgage Loans, such access being
afforded without charge but only upon reasonable advance request and during
normal business hours at the offices of the Servicer designated by it.

                (b) The Servicer, in its capacity as an Originator and Servicer,
shall afford the NIMS Insurer, upon reasonable advance notice, during normal
business hours, access to all records maintained by the Servicer in respect of
its rights and obligations hereunder and access to officers of the Servicer
responsible for such obligations. Upon request, the Servicer shall furnish to
the NIMS Insurer its most recent publicly available financial statements and
such other information relating to its capacity to perform its obligations under
this Agreement.

                Section 3.22   Duties of Credit Risk Manager.

                For and on behalf of the Depositor, the Credit Risk Manager
shall provide reports and recommendations as to loss mitigation activities
concerning Mortgage Loans that are past due, are in default, as to which there
has been commencement of foreclosure, as to which there has been forbearance in
exercise of remedies, as to which any obligor is the subject of bankruptcy,
receivership, or an arrangement of creditors, or which have become REO
Properties. Such reports and recommendations will be based upon information
provided pursuant to the Credit Risk Management Agreement. The Credit Risk
Manager shall look solely to the Servicer for all information and data
(including loss and delinquency information and data) and loan-level information
and data relating to the servicing of the Mortgage Loans.

                The Credit Risk Manager may be removed at any time by a vote of
Certificateholders holding Certificates evidencing at least 66 2/3% of the
aggregate Voting Rights of the Certificates. After any such termination, the
Credit Risk Manager shall have no further obligations hereunder, and shall no
longer be entitled to the Credit Risk Manager Fee.

                Section 3.23   Obligations of the Servicer in Respect of
Compensating Interest.

                Not later than the close of business on each Servicer Remittance
Date, the Servicer shall deliver to the Trustee for deposit in the Distribution
Account an amount ("Compensating Interest") equal to the lesser of (A) the
aggregate of the Prepayment Interest Shortfalls on the Mortgage Loans for the
related Distribution Date resulting from Principal Prepayments in full on the
Mortgage Loans during the related Prepayment Period and (B) the aggregate
Servicing Fee received in the related Collection Period. The Servicer shall
apply Compensating Interest to offset any Prepayment Interest Shortfalls
resulting from Principal Prepayments in full on the Mortgage Loans. The Servicer
shall not have the right to reimbursement for any amounts remitted to the
Trustee in respect of Compensating Interest. Such amounts so remitted shall be
included in the Available Funds and distributed therewith on the next
Distribution Date. The Servicer shall not be obligated to pay Compensating
Interest with respect to Prepayment Interest Shortfalls resulting from partial
Principal Prepayments or Relief Act Interest Shortfalls.

                Section 3.24   Obligations of the Servicer in Respect of
Mortgage
Interest Rates and Monthly Payments.

                In the event that a shortfall in any collection on or liability
with respect to any Mortgage Loan results from or is attributable to adjustments
to Mortgage Interest Rates, Monthly Payments or Principal Balances that were
made by the Servicer in a manner not consistent with the terms of the related
Mortgage Note and this Agreement, the Servicer, upon discovery or receipt of
notice thereof, immediately shall deliver to the Trustee for deposit in the
Distribution Account from its own funds the amount of any such shortfall and
shall indemnify and hold harmless the Trust Fund, the Trustee, the Depositor and
any successor servicer in respect of any such liability. Such indemnities shall
survive the termination or discharge of this Agreement. Notwithstanding the
foregoing, this Section 3.24 shall not limit the ability of the Servicer to seek
recovery of any such amounts from the related Mortgagor under the terms of the
related Mortgage Note, as permitted by law.

                Section 3.25   Investment of Funds in the Collection Account and
the Distribution Account.

                (a) The Servicer may direct any depository institution
maintaining the Collection Account and the Trustee may direct any depository
institution maintaining the Distribution Account (for purposes of this Section
3.25, each an "Investment Account"), to invest the funds in such Investment
Account in one or more Eligible Investments bearing interest or sold at a
discount, and maturing, unless payable on demand, (i) no later than the Business
Day immediately preceding the date on which such funds are required to be
withdrawn from such account pursuant to this Agreement, if a Person other than
the Trustee is the obligor thereon, and (ii) no later than the date on which
such funds are required to be withdrawn from such account pursuant to this
Agreement, if the Trustee is the obligor thereon or if such investment is
managed or advised by the Trustee or an Affiliate of the Trustee. All such
Eligible Investments shall be held to maturity, unless payable on demand. Any
investment of funds in an Investment Account shall be made in the name of the
Trustee or the Servicer, as applicable (in its capacity as such) or in the name
of a nominee of the Trustee. The Trustee shall be entitled to sole possession
(except with respect to investment direction of funds held in the Collection
Account) over each such investment and the income thereon, and any certificate
or other instrument evidencing any such investment shall be delivered directly
to the Trustee or its agent, together with any document of transfer necessary to
transfer title to such investment to the Trustee or its nominee. In the event
amounts on deposit in an Investment Account are at any time invested in an
Eligible Investment payable on demand, the Trustee shall at the direction of the
Servicer:

                        (x)     consistent with any notice required to be given
                                thereunder, demand that payment thereon be made
                                on the last day such Eligible Investment may
                                otherwise mature hereunder in an amount equal to
                                the lesser of (1) all amounts then payable
                                thereunder and (2) the amount required to be
                                withdrawn on such date; and

                        (y)     demand payment of all amounts due thereunder
                                promptly upon determination by a Responsible
                                Officer of the Trustee that such Eligible
                                Investment would not constitute an Eligible
                                Investment in respect of funds thereafter on
                                deposit in the Investment Account.

                (b) All income and gain realized from the investment of funds in
the Collection Account shall be for the benefit of the Servicer. The Servicer
shall deposit in the Collection Account or (to the extent funds in the Escrow
Account are invested if permitted by applicable law) the Escrow Account, as
applicable, from its own funds the amount of any loss incurred in respect of any
such Eligible Investment made with funds in such account immediately upon
realization of such loss. All income and gain realized from the investment of
funds in the Distribution Account shall be for the benefit of the Trustee. The
Trustee shall deposit in the Distribution Account from its own funds the amount
of any loss incurred on Eligible Investments in the Distribution Account.

                (c) Except as otherwise expressly provided in this Agreement, if
any default occurs in the making of a payment due under any Eligible Investment,
or if a default occurs in any other performance required under any Eligible
Investment, the Trustee may and, subject to Section 8.01 and Section 8.02(a)(v),
upon the request of the NIMS Insurer or Holders of Certificates representing
more than 50% of the Voting Rights allocated to any Class of Certificates, shall
take such action as may be appropriate to enforce such payment or performance,
including the institution and prosecution of appropriate proceedings.

                The Trustee shall not in any way be held liable by reason of any
insufficiency in any Account held by the Trustee resulting from any investment
loss on any Eligible Investment included therein (except to the extent that the
Trustee is the obligor and has defaulted thereon).

                Section 3.26   Liability of Servicer; Indemnification.

                (a) Subject to clause (b) below and Section 6.03, the Servicer
(except the Trustee if it is required to succeed the Servicer hereunder)
indemnifies and holds the Trustee, the Depositor, the NIMS Insurer and the Trust
Fund harmless against any and all third party claims, losses, penalties, fines,
forfeitures, reasonable legal fees and related costs, judgments, and any other
costs, fees and expenses that the Trustee, the Depositor, the NIMS Insurer and
the Trust Fund may sustain in any way related to the failure of the Servicer to
perform its duties and service the Mortgage Loans in compliance with the
Servicing Standard, including, but not limited to the Servicer's obligation to
deliver any information, report, certification, accountants' letter or other
material required to comply with Regulation AB or (b) any material breach by the
Servicer or any of the representations and warranties contained in Section 2.05.
The Servicer shall immediately notify the Trustee, the NIMS Insurer and the
Depositor if a claim is made that may result in such claims, losses, penalties,
fines, forfeitures, legal fees or related costs, judgments, or any other costs,
fees and expenses, and the Servicer shall assume (with the consent of the
Trustee) the defense of any such claim and pay all expenses in connection
therewith, including reasonable counsel fees, and promptly pay, discharge and
satisfy any judgment or decree which may be entered against the Servicer, the
Trustee, the Depositor, the NIMS Insurer and/or the Trust Fund in respect of
such claim. The provisions of this Section 3.26 shall survive the termination of
this Agreement and the payment of the outstanding Certificates.

                (b) None of the Depositor, the NIMS Insurer, the Servicer, or
any of the directors, officers, employees or agents of the Depositor or the
Servicer shall be under any liability to the Trust Fund or the
Certificateholders for any action taken, or for refraining from the taking of
any action, in good faith pursuant to this Agreement, or for errors in judgment;
provided, however, that this provision shall not protect the Depositors, the
NIMS Insurer or the Servicer or any such Person against any breach of warranties
or representations made by such party herein, or against any specific liability
imposed on the Servicer for a breach of the Servicing Standard and/or this
Agreement, or against any liability which would otherwise be imposed by reason
of its respective willful misfeasance, bad faith, fraud or negligence in the
performance of its duties or by reasons of negligent disregard of its respective
obligations or duties hereunder.

                The Depositor, the NIMS Insurer, the Servicer and any director,
officer, employee or agent of the Depositor, the NIMS Insurer or the Servicer,
may rely in good faith on any document of any kind which, prima facie, is
properly executed and submitted by any appropriate Person with respect to any
matters arising hereunder. The Depositor, the Servicer, the NIMS Insurer and any
director, officer, employee or agent of the Depositor, the Servicer or the NIMS
Insurer shall be indemnified and held harmless by the Trust against any loss,
liability or expense incurred in connection with any legal action relating to
this Agreement or the Certificates, other than any loss, liability or expense
incurred in connection with any legal action incurred by reason of its
respective misfeasance, bad faith, fraud or negligence, a breach of a
representation or warranty made by such party hereunder or (in the case of the
Servicer) a breach of the Servicing Standard in the performance of its
respective duties or by reason of negligent disregard of its respective
obligations or duties hereunder. Neither the Depositor, the NIMS Insurer, nor
the Servicer shall be under any obligation to appear in, prosecute or defend any
legal action unless such action is related to its respective duties under this
Agreement and in its opinion does not expose it to any expense or liability;
provided, however, that the Depositor, the NIMS Insurer or the Servicer may in
their discretion undertake any action related to their obligations hereunder
which they may deem necessary or desirable with respect to this Agreement and
the rights and duties of the parties hereto and the interests of the
Certificateholders hereunder. The Servicer's right to indemnity or reimbursement
pursuant to this Section shall survive any resignation or termination of the
Servicer pursuant to Section 6.04 or 7.01 with respect to any losses, expenses,
costs or liabilities arising prior to such resignation or termination (or
arising from events that occurred prior to such resignation or termination).

                Section 3.27   Reports of Foreclosure and Abandonment of
Mortgaged Properties.

                Beginning in 2006, the Servicer shall file the reports of
foreclosure and abandonment of any Mortgaged Property required by Section 6050J
of the Code with the Internal Revenue Service on or before the due date for any
such report. Not later than 90 days following the end of each calendar year,
beginning in 2006, the Servicer will deliver an Officer's Certificate to the
Trustee and the NIMS Insurer certifying its compliance with this Section 3.27.
The reports from the Servicer shall be in form and substance sufficient to meet
the reporting requirements imposed by such Section 6050J.

                Section 3.28   Protection of Assets.

                (a) Except for transactions and activities entered into in
connection with the securitization that is the subject of this Agreement, the
Trust is not authorized and has no power to:

                        (1) borrow money or issue debt;

                        (2) merge with another entity, reorganize, liquidate or
                sell assets; or

                        (3) engage in any business or activities.

                (b) Each party to this Agreement agrees that it will not file an
involuntary bankruptcy petition against the Trustee or the Trust Fund or
initiate any other form of insolvency proceeding until after the Certificates
have been paid.

                Section 3.29   Limitation of Liability of the Credit Risk
Manager.

                Neither the Credit Risk Manager, nor any of the directors,
officers, employees or agents of the Credit Risk Manager, shall be under any
liability to the Depositor, the Servicer, the Trustee or the Certificateholders
for any action taken or for refraining from the taking of any action in good
faith pursuant to this Agreement, in reliance upon information provided by the
Servicer under the Credit Risk Management Agreement or for errors in judgment;
provided, however, that this provision shall not protect the Credit Risk Manager
or any such person against liability that would otherwise be imposed by reason
of willful malfeasance, bad faith or negligence in its performance of its duties
or by reason of reckless disregard for its obligations and duties under this
Agreement or the applicable Credit Risk Management Agreement. The Credit Risk
Manager and any director, officer, employee or agent of the Credit Risk Manager
may rely in good faith on any document of any kind prima facie properly executed
and submitted by any Person respecting any matters arising hereunder, and may
rely in good faith upon the accuracy of information furnished by the Servicer
pursuant to the applicable Credit Risk Management Agreement in the performance
of its duties thereunder and hereunder.

                Section 3.30   No Personal Solicitation.

                From and after the Closing Date, the Servicer agrees that it
will not take any action or permit or cause any action to be taken by any of its
agents and Affiliates, or by any independent contractors or independent mortgage
brokerage companies on the Servicer's behalf, to personally, by telephone, mail
or electronic mail, solicit the Mortgagor under any Mortgage Loan for the
purpose of refinancing such Mortgage Loan; provided, that the Servicer may (i)
with respect to each Adjustable Rate Mortgage Loan, solicit any Mortgagor 60
days prior to the later of the expiration of (a) any applicable prepayment
penalty period or (b) the applicable fixed-rate period and (ii) with respect to
each Fixed-Rate Mortgage Loan, solicit any Mortgagor 60 days prior to the later
of (a) the expiration of any applicable prepayment penalty period or (b) 24
months after its origination; provided, further, that the Servicer may solicit
any Mortgagor for whom the Servicer has received a request for verification of
mortgage, a request for demand for payoff, a mortgagor initiated written or
verbal communication indicating a desire to prepay the related Mortgage Loan, or
the mortgagor initiates a title search; provided further, it is understood and
agreed that promotions undertaken by the Servicer or any of its Affiliates which
(i) concern optional insurance products or other additional products or (ii) are
directed to the general public at large, including, without limitation, mass
mailings based on commercially acquired mailing lists, newspaper, radio and
television advertisements shall not constitute solicitation under this Section,
nor is the Servicer prohibited from responding to unsolicited requests or
inquiries made by a Mortgagor or an agent of a Mortgagor. Furthermore, the
Servicer shall be permitted to include in its monthly statements to borrowers or
otherwise, statements regarding the availability of the Servicer's counseling
services with respect to refinancing mortgage loans.

                Section 3.31   Periodic Filings.

                (a) The Trustee and the Servicer shall reasonably cooperate with
the Depositor to enable the Depositor to satisfy its reporting requirements
under the Exchange Act and the parties hereto shall reasonably cooperate to
enable the Commission's requirements with respect to the Depositor to be met in
the event that the Commission issues additional interpretive guidelines or
promulgates rules or regulations, or in the event of any other change of law
that would require reporting arrangements or the allocation of responsibilities
with respect thereto, as described in this Section 3.31, to be conducted or
allocated in a different manner. Without limiting the generality of the
foregoing, the Trustee shall prepare on behalf of the Depositor any Current
Reports on Form 8-K (each, a "Form 8-K"), Distribution Reports on Form 10-D
(each, a "Form 10-D") and Annual Reports on Form 10-K (each, a "Form 10-K") as
required by the Exchange Act and the rules and regulations of the Commission
thereunder, the Depositor shall sign and the Trustee shall file (via the
Commission's Electronic Data Gathering and Retrieval System) such Forms on
behalf of the Depositor. Notwithstanding the foregoing, the Depositor shall
prepare, sign and file the Form 8-K in connection with the issuance of the
Certificates.

                (b) Each Form 10-D shall be prepared and filed in the form and
substance as required by the Exchange Act by the Trustee within 15 days after
each Distribution Date (subject to permitted extensions under the Exchange Act)
and shall include a copy of the Distribution Date Statement for such
Distribution Date as an exhibit thereto. In addition, the Trustee shall include
under Item 1 of each Form 10-D any information required by Item 1121 of
Regulation AB to the extent relevant that is not included on the Distribution
Date Statement. Any information in addition to the Distribution Date Statement
and any other information required by Item 1121 of Regulation AB ("Additional
Form 10-D Information") shall be determined by the party preparing such
information as set forth on Exhibit R-1 hereto and the Trustee shall compile
such information pursuant to the following paragraph. The Trustee will have no
duty or liability for any failure hereunder to determine or prepare any
Additional Form 10-D Information, except to the extent of its obligations as set
forth in the next paragraph.

                As set forth on Exhibit R-1 hereto, within five (5) calendar
days (or, solely in the case of Item 7 listed on Exhibit R-1, the greater of
five (5) calendar days or three (3) Business Days) after the related
Distribution Date, (i) the parties described on Exhibit R-1 shall be required to
provide to the Depositor and the Trustee, to the extent known by such parties,
in EDGAR-compatible format, or in such other form as otherwise agreed upon by
the Trustee and such party, any Additional Form 10-D Information, if applicable,
together with an Additional Disclosure Notification in the form of Exhibit U
hereto (an "Additional Disclosure Notification") and (ii) the Depositor will
approve, as to form and substance, or disapprove, as the case may be, the
inclusion of the Additional Form 10-D Information (other than with respect to
Additional Form 10-D Information provided by the Trustee). The Depositor will be
responsible for all reasonable fees and expenses assessed or incurred by the
Trustee in connection with including any Additional Form 10-D Information on
Form 10-D pursuant to this paragraph, including converting any such information
to an EDGAR-compatible format.

                After preparing the Form 10-D, the Trustee shall forward
electronically a copy of the Form 10-D to the Depositor for review. No later
than 2 Business Days prior to the 15th calendar day after the related
Distribution Date, the Depositor shall sign the Form 10-D and return an
electronic or fax copy of such signed Form 10-D (with an original executed hard
copy to immediately follow) to the Trustee. If a Form 10-D cannot be filed on
time or if a previously filed Form 10-D needs to be amended, the Trustee will
follow the procedures set forth in Section 3.31(e). Form 10-D requires the
registrant to indicate (by checking "yes" or "no") that it "(1) has filed all
reports required to be filed by Section 13 or 15(d) of the Exchange Act during
the preceding 12 months (or for such shorter period that the registrant was
required to file such reports), and (2) has been subject to such filing
requirements for the past 90 days." The Depositor hereby instructs the Trustee,
with respect to each Form 10-D, to check "yes" for each item unless the Trustee
has received timely prior written notice from the Depositor that the answer
should be "no" for an item. Promptly (but no later than one Business Day) after
filing with the Commission, the Trustee will make available on its internet
website a final executed copy of each Form 10-D. Each party to this Agreement
acknowledges that the performance by the Trustee of its duties under this
Section 3.31(b) related to the timely preparation, arrangement for execution and
filing of Form 10-D is contingent upon such parties strictly observing all
applicable deadlines in the performance of their duties under this Section
3.31(b). The Trustee shall have no liability for any loss, expense, damage or
claim arising out of or with respect to any failure to properly prepare and/or
timely file such Form 10-D, where such failure results from the Trustee's
inability or failure to obtain or receive, on a timely basis, any information
from any party hereto or any Servicing Function Participant or any party hereto
(other than the Trustee or any Servicing Function Participant utilized by the
Trustee) needed to prepare, arrange for execution or file such Form 10-D, not
resulting from its own negligence, bad faith or wilful misconduct.

                (c) On or before 90 days after the end of each fiscal year of
the Trust (or such earlier date as may be required by the Exchange Act and the
rules and regulations of the Commission) (the "10-K Filing Deadline") commencing
in 2007, the Trustee shall prepare and file a Form 10-K, in form and substance
as required by applicable law or applicable Commission staff interpretations.
Each such Form 10-K shall include the following items, in each case to the
extent they have been delivered to the Trustee within the applicable time frames
set forth in this Agreement: (i) a Compliance Statement for the Trustee, the
Servicer and each Additional Servicer, as described under Section 3.19, (ii)(A)
the Assessment of Compliance for each of the Servicer, the Trustee and each
Servicing Function Participant, as described under Section 3.20, and (B) if the
Servicer's, the Trustee's or each Servicing Function Participant's Assessment of
Compliance described under Section 3.20 identifies any material instance of
noncompliance or is not included, disclosure identifying such instance of
noncompliance or disclosure that such report is not included and an explanation
thereof, as the case may be, (iii)(A) the registered public accounting firm
Attestation Report for the Servicer, the Trustee and each Servicing Function
Participant, as described under Section 3.20, and (B) if any registered public
accounting firm Attestation Report described under Section 3.20 identifies any
material instance of noncompliance or is not included, disclosure identifying
such instance of noncompliance or disclosure that such report is not included
and an explanation thereof, as the case may be, and (iv) a Sarbanes-Oxley
Certification. Any information in addition to (i) through (iv) above that is
required to be included on Form 10-K ("Additional Form 10-K Information") shall
be reported by the party responsible for preparing such information as set forth
on Exhibit R-2 hereto and the Trustee shall compile such information pursuant to
the following paragraph. The Trustee will have no duty or liability for any
failure hereunder to determine or prepare any Additional Form 10-K Information,
except to the extent of its obligations as set forth in the next paragraph.

                As set forth on Exhibit R-2 hereto, no later than March 1st of
each year that the Trust is subject to the Exchange Act reporting requirements,
commencing in 2007 (i) the parties described in Exhibit R-2 shall be required to
provide to the Trustee and the Depositor, to the extent known by such applicable
parties, in EDGAR-compatible format, or in such other form as otherwise agreed
upon by the Trustee and such party, any Additional Form 10-K Information, if
applicable, together with an Additional Disclosure Notification and (ii) the
Depositor will approve, as to form and substance, or disapprove, as the case may
be, the inclusion of the Additional Form 10-K Information (other than with
respect to Additional Form 10-K Information provided by the Trustee). The
Depositor will be responsible for all reasonable fees and expenses assessed or
incurred by the Trustee in connection with including any Additional Form 10-K
Information on Form 10-K pursuant to this paragraph, including converting any
such information to an EDGAR-compatible format.

                After preparing the Form 10-K, the Trustee shall forward
electronically a copy of the Form 10-K to the Depositor for review. No later
than the close of business on the fourth Business Day prior to the 10-K Filing
Deadline, a senior officer of the Depositor in charge of securitization shall
sign the Form 10-K and return an electronic or fax copy of such signed Form 10-K
to the Trustee. If a Form 10-K cannot be filed on time or if a previously filed
Form 10-K needs to be amended, the Trustee will follow the procedures set forth
in Section 3.31(e). The Depositor hereby instructs the Trustee, with respect to
each Form 10-K, to check "yes" for each item unless the Trustee has received
timely prior written notice from the Depositor that the answer should be "no"
for an item. Promptly (but no later than one Business Day) after filing with the
Commission, the Trustee will make available on its internet website a final
executed copy of each Form 10-K. The parties to this Agreement acknowledge that
the performance by the Trustee of its duties under this Section 3.31(c) relating
to the timely preparation and filing of Form 10-K is contingent upon such
parties (and any Additional Servicer or Servicing Function Participant) strictly
observing all applicable deadlines in the performance of their duties under this
Section 3.31, Section 3.19 and Section 3.20. The Trustee shall have no liability
for any loss, expense, damage, claim arising out of or with respect to any
failure to properly prepare and/or timely file such Form 10-K, where such
failure results from the Trustee's inability or failure to obtain or receive, on
a timely basis, any information from any party hereto or any Servicing Function
Participant (other than the Trustee or any Servicing Function Participant
utilized by the Trustee) needed to prepare, arrange for execution or file such
Form 10-K, not resulting from its own negligence, bad faith or willful
misconduct.

                The Form 10-K shall also include a certification in the form
attached hereto as Exhibit O (the "Sarbanes-Oxley Certification"), which shall
be signed by a senior officer of the Depositor in charge of securitization. The
Depositor shall deliver the Sarbanes-Oxley Certification to the Trustee four (4)
Business Days prior to the latest date on which the Form 10-K may be timely
filed.

                For so long as the Trust is subject to the reporting
requirements of the Exchange Act, the Trustee and the Servicer shall provide,
and shall cause any Servicing Function Participant engaged by it to provide, to
the Depositor, on or before March 15th of each year, commencing in March 2007,
and otherwise within a reasonable time upon request, a certification in the form
attached hereto as Exhibit P-1, in the case of the Trustee, and Exhibit P-2, in
the case of the Servicer. In the event the Trustee or the Servicer is terminated
or resigns pursuant to the terms of this Agreement, such Trustee or Servicer
shall provide a certification in the form attached hereto as Exhibit P-1, in the
case of the Trustee, or Exhibit P-2, in the case of the Servicer, with respect
to the period of time it was subject to this Agreement. In the event that prior
to the filing date of the Form 10-K in March of each year, the Trustee or the
Servicer has actual knowledge of information material to the Sarbanes-Oxley
Certification, that party shall promptly notify the Depositor and each of the
other parties signing the certifications.

                In addition, (i) the Trustee shall indemnify and hold harmless
the Depositor, the Servicer, the Sponsor and their officers, directors and
Affiliates from and against any losses, damages, penalties, fines, forfeitures,
reasonable and necessary legal fees and related costs, judgments and other costs
and expenses arising out of or based upon (A) any inaccuracy in the Assessment
of Compliance with the Servicing Criteria pursuant to Section 3.20 provided by
the Trustee or any Servicing Function Participant appointed by the Trustee and
(B) any inaccuracy in the certification provided by the Trustee pursuant to this
Section 3.31(c), and (C) any breach by the Trustee of its obligations (or of the
obligations of any Servicing Function Participant appointed by the Trustee)
under Sections 3.20 and 3.31 or the Trustee's or such Servicing Function
Participant's negligence, bad faith or willful misconduct in connection
therewith and (ii) the Servicer shall indemnify and hold harmless the Depositor,
the Sponsor, the Trustee and their respective officers, directors, employees,
agents and Affiliates from and against any losses, damages, penalties, fines,
forfeitures, reasonable and necessary legal fees and related costs, judgments
and other costs and expenses arising out of or based upon (A) any inaccuracy in
the Assessment of Compliance with the Servicing Criteria pursuant to Section
3.20 provided by the Servicer or any Servicing Function Participant appointed by
the Servicer, (B) any inaccuracy in the certification provided by the Servicer
pursuant to this Section 3.31(c), and (C) any breach by the Servicer of its
obligations (or of the obligations of any Servicing Function Participant
appointed by the Servicer) under Sections 3.20 and 3.31 or the Servicer's or
such Servicing Function Participant's negligence, bad faith or willful
misconduct in connection therewith. If the indemnification provided for herein
is unavailable or insufficient to hold harmless the Depositor, the Servicer, the
Trustee and the Sponsor and their officers, directors and Affiliates, then the
indemnifying party agrees that it shall contribute to the amount paid or payable
by the indemnified party and any of their officers, directors or Affiliates as a
result of the losses, claims, damages or liabilities of the indemnified party,
any of their officers, directors or Affiliates in such proportion as is
appropriate to reflect the relative fault of the indemnifying party and each of
their officers, directors and Affiliates on the one hand and the indemnified
party on the other in connection with a breach of the indemnifying party's
obligations under this Section 3.31(c) or Section 3.20 or the indemnifying
party's negligence, bad faith or willful misconduct in connection therewith. The
Servicer hereby acknowledges and agrees that the Depositor and the Trustee are
relying on the Servicer's performance of its obligations under Sections 3.19,
3.20 and 3.31 in order to perform their respective obligations under this
Section 3.31.

                (d) Within four (4) Business Days (or, in the case of any
information disclosed pursuant to Item 7.01 of Form 8-K, within the time period
required by Regulation FD) after the occurrence of an event requiring disclosure
on Form 8-K (each such event, a "Reportable Event"), and also if requested by
the Depositor, the Trustee shall prepare and file on behalf of the Trust any
Form 8-K, as required by the Exchange Act, provided that the Depositor shall
file the initial Form 8-K in connection with the issuance of the Certificates.
Any information related to a Reportable Event or that is otherwise required to
be included on Form 8-K other than the initial Form 8-K (such information, "Form
8-K Information") shall be reported to the Depositor and the Trustee by the
parties set forth on Exhibit R-3 hereto and compiled by the Trustee pursuant to
the following paragraph. The Trustee will have no duty or liability for any
failure hereunder to determine or prepare any Form 8-K Information or any Form
8-K, except to the extent of its obligations as set forth in the next paragraph.

                As set forth on Exhibit R-3 hereto, for so long as the Trust is
subject to the Exchange Act reporting requirements, no later than 12:00 noon EST
on the second Business Day after the occurrence of a Reportable Event (i) the
parties described in Exhibit R-3 shall be required to provide to the Depositor
and the Trustee, to the extent known by such applicable parties, in
EDGAR-compatible format, or in such other form as otherwise agreed upon by the
Trustee and such party, any Form 8-K Information, if applicable, together with
an Additional Disclosure Notification and (ii) the Depositor will approve, as to
form and substance, or disapprove, as the case may be, the inclusion of the
Additional Form 8-K Information (other than with respect to Additional Form 8-K
Information provided by the Trustee). The Depositor will be responsible for all
reasonable fees and expenses assessed or incurred by the Trustee in connection
with including any Form 8-K Information on Form 8-K pursuant to this paragraph,
including converting any such information to an EDGAR-compatible format.

                After preparing the Form 8-K, the Trustee shall forward
electronically a draft copy of the Form 8-K to the Depositor for review,
verification and execution by the Depositor. No later than 12:00 noon EST on the
third Business Day after the Reportable Event, an officer of the Depositor shall
sign the Form 8-K and return an electronic or fax copy of such signed Form 8-K
(with an original executed hard copy to follow by overnight mail) to the
Trustee. Promptly (but no later than one Business Day) after filing with the
Commission, the Trustee will, make available on its internet website a final
executed copy of each Form 8-K prepared and filed by it. If a Form 8-K cannot be
filed on time or if a previously filed Form 8-K needs to be amended, the Trustee
will follow the procedures set forth in Section 3.31(e). The parties hereto
acknowledge that the performance by the Trustee of its duties under this Section
3.31(d) related to the timely preparation and filing of Form 8-K is contingent
upon the parties to this Agreement and any other Person obligated to provide
Form 8-K Information as set forth on Exhibit R-3 hereto, observing all
applicable deadlines in the performance of their duties under this Section
3.31(d). The Trustee shall have no liability for any loss, expense, damage or
claim arising out of or with respect to any failure to properly prepare and/or
timely file such Form 8-K, where such failure results from the Trustee's
inability or failure to obtain or receive, on a timely basis, any information
from any party hereto or any Servicing Function Participant (other than the
Trustee or any Servicing Function Participant utilized by the Trustee) needed to
prepare, arrange for execution or file such Form 8-K, not resulting from its own
negligence, bad faith or willful misconduct.

                (e) In the event that the Trustee is unable to timely file with
the Commission all or any required portion of any Form 8-K, Form 10-D or Form
10-K required to be filed by this Agreement because required information was
either not delivered to it or delivered to it after the delivery deadlines set
forth in this Agreement or for any other reason, the Trustee will immediately
notify the Depositor. In the case of Form 10-D and Form 10-K, the Depositor,
Servicer and Trustee will cooperate to prepare and file a Form 12b-25 pursuant
to Rule 12b-25 of the Exchange Act. In the case of Form 8-K, the Trustee will,
upon receipt of all information required to be included on Form 8-K, file such
Form 8-K. Within 5 calendar days following the original due date of the Form
10-D, the Trustee shall prepare and file the related Form 10-D. Within 15
calendar days following the original due date of the Form 10-K, the Trustee
shall prepare and file the related Form 10-K. In the event that any previously
filed Form 8-K, Form 10-D or Form 10-K needs to be amended, the party to this
Agreement deciding that an amendment to such Form 8-K, Form 10-D or Form 10-K is
required will notify the Depositor, the Trustee and the Servicer and such
parties will cooperate to prepare any necessary Form 8-K/A, Form 10-D/A or Form
10-K/A. Any Form 12b-25 or any amendment to Form 10-D or Form 10-K shall be
signed by a senior officer of the Depositor. Any amendment to Form 8-K or any
Form 15 (as described in Section 3.31(g)) shall be signed by an officer of the
Depositor. The Depositor and Servicer acknowledge that the performance by the
Trustee of its duties under this Section 3.31(e) related to the timely
preparation and filing of a Form 12b-25 or any amendment to Form 8-K, Form 10-D
or Form 10-K is contingent upon the Servicer and the Depositor performing their
duties under this Section. The Trustee shall have no liability for any loss,
expense, damage, claim arising out of or with respect to any failure to properly
prepare and/or timely file any such Form 12b-25 or any amendments to Form 8-K,
Form 10-D or Form 10-K, where such failure results from the Trustee's inability
or failure to obtain or receive, on a timely basis, any information from any
other party hereto (other than the Trustee or any Servicing Function Participant
utilized by the Trustee) needed to prepare, arrange for execution or file such
Form 12b-25 or any amendments to Form 8-K, Form 10-D or Form 10-K, not resulting
from its own negligence, bad faith or willful misconduct.

                (f) Upon any filing with the Commission, the Trustee shall
promptly deliver or otherwise make available to the Depositor a copy of any such
executed report, statement or information.

                (g) The obligations set forth in paragraphs (a) through (f) of
this Section shall only apply with respect to periods for which the Trustee is
obligated to file reports on Form 8-K, 10-D or 10-K. Unless otherwise instructed
by the Depositor, on or prior to January 30th of the first year in which the
Trustee is permitted to do so under Section 15(d) of the Exchange Act and other
applicable law and regulations, the Trustee shall prepare (and the Depositor
shall execute) and file with the Commission a Form 15 Suspension Notification
with respect to the Trust, with a copy to the Depositor. If at the beginning of
any year after the filing of a Form 15 Suspension Notification, if the number of
Certificateholders of record exceeds the number set forth in Section 15(d) of
the Exchange Act or the regulations promulgated pursuant thereto which would
cause the Trust to again become subject to the reporting requirements of the
Exchange Act, the Trustee shall recommence preparing and filing reports on Form
8-K, 10-D and 10-K as required pursuant to this Section and the parties hereto
will again have the obligations set forth in paragraphs (a) through (f) of this
Section until such time as the Trustee is again able to file with the Commission
a Form 15 Suspension Notification with respect to the Trust.

                (h) The Depositor, the Trustee and the Servicer shall notify the
Depositor and the Trustee of any proceedings of the type described in Item 1117
of Regulation AB, together with a description thereof, within five Business Days
of any such party's knowledge thereof. In addition, the Depositor, the Trustee
and the Servicer shall notify the Depositor and the Trustee of any affiliations
or relationships that develop following the Closing Date between the Depositor,
the Trustee or the Servicer and any of parties listed in Item 1119 of Regulation
AB, together with a description thereof, within five Business Days of any such
party's knowledge thereof.

                (i) The Trustee, the Depositor and the Servicer shall reasonably
cooperate to enable the Commission's requirements with respect to the Trust to
be met in the event that the Commission issues additional interpretive
guidelines or promulgates rules or regulations, or in the event of any other
change of law that would require reporting arrangements or the allocation of
responsibilities with respect thereto, as described in this Section 3.31, to be
conducted or allocated in a different manner.

        warranties.

                The Trustee may fully rely upon and shall have no liability with
respect to information with respect to the Mortgage Loans provided by the
Servicer.

                In determining whether a breach of a representation or warranty
relating to the Mortgage Loans is material or whether a breach of a transaction
covenant or representation or warranty is material for purposes of subclause
(xxxii) above, the Trustee may consult with the Depositor and rely on the
Depositor's determination of materiality.

                In the case of information furnished pursuant to subclauses (i),
(ii) and (xiii) above, the amounts shall be expressed in a separate section of
the report as a dollar amount for each Class for each $1,000 original dollar
amount as of the Cut-off Date.

                The Trustee will also make available copies of the periodic
reports the Trustee prepares and files with the Commission, including
distribution reports on Form 10-D, annual reports on Form 10-K, current reports
on Form 8-K and amendments to these reports available through www.ctslink.com
promptly (but no later than one Business Day) after the Trustee has filed such
reports with the Commission.

                (b) Within a reasonable period of time after the end of each
calendar year, the Trustee shall furnish to the NIMS Insurer and each Person who
at any time during the calendar year was a Certificateholder of a Regular
Certificate, if requested in writing by such Person, such information as is
reasonably necessary to provide to such Person a statement containing the
information set forth in subclauses (i), (ii), (xiv) and (xvi) above, aggregated
for such calendar year or applicable portion thereof during which such Person
was a Certificateholder. Such obligation of the Trustee shall be deemed to have
been satisfied to the extent that substantially comparable information shall be
prepared and furnished by the Trustee to Certificateholders pursuant to any
requirements of the Code as are in force from time to time.

                (c) On each Distribution Date, the Trustee shall forward to each
Residual Certificateholder a copy of the reports forwarded to the Regular
Certificateholders in respect of such Distribution Date with such other
information as the Trustee deems necessary or appropriate. Such obligation of
the Trustee shall be deemed to have been satisfied to the extent that
substantially comparable information shall be prepared and furnished to each
Residual Certificateholder by the Trustee pursuant to any requirements of the
Code as from time to time in force.

                (d) For all purposes of this Agreement including, but not
limited to, providing the information set forth in clause (viii) of Section
4.06(a), with respect to any Mortgage Loan, delinquencies shall be determined
and reported based on the so-called "OTS" methodology for determining
delinquencies on mortgage loans similar to the Mortgage Loans. By way of
example, a Mortgage Loan would be one payment delinquent with respect to a
Monthly Payment due on a Due Date if such Monthly Payment is not made by the
close of business on the Mortgage Loan's next succeeding Due Date, and a
Mortgage Loan would be two payments delinquent with respect to such Monthly
Payment if such Monthly Payment were not made by the close of business on the
Mortgage Loan's second succeeding Due Date. The Servicer hereby represents and
warrants to the Depositor that this delinquency recognition policy is its
current policy and is not less restrictive than any delinquency recognition
policy established by the primary safety and soundness regulator, if any, of the
Servicer.

                Section 4.07   Remittance Reports; Advances.

                (a) On the third Business Day following each Determination Date
but in no event later than the 20th day of each month (or if such 20th day is
not a Business Day, the preceding Business Day), the Servicer shall deliver to
the Trustee and the NIMS Insurer by telecopy (or by such other means as the
Servicer, the NIMS Insurer and the Trustee may agree from time to time) a
Remittance Report with respect to the related Distribution Date. On the same
date, the Servicer shall electronically forward to the Trustee in such medium as
may be agreed between the Servicer and the Trustee the information set forth in
such Remittance Report with respect to the related Distribution Date and such
information reasonably available to the Servicer necessary in order for the
Trustee to perform the calculations necessary to make the distributions and
allocations contemplated by Section 4.01, 4.02, 4.03 and 4.11 and to prepare the
Distribution Date Statement. The Trustee shall not be responsible to recompute,
recalculate or verify any information provided to it by the Servicer.

                (b) The amount of Advances to be made by the Servicer for any
Distribution Date shall equal, subject to Section 4.07(d), the sum of (i) the
aggregate amount of Monthly Payments (net of the related Servicing Fee), due
during the related Collection Period in respect of the Mortgage Loans, which
Monthly Payments were delinquent on a contractual basis as of the close of
business on the related Determination Date, and (ii) with respect to each REO
Property, which REO Property was acquired during or prior to the related
Collection Period and as to which REO Property an REO Disposition did not occur
during the related Collection Period, an amount equal to the excess, if any, of
the REO Imputed Interest on such REO Property for such Collection Period, over
the net income from such REO Property transferred to the Distribution Account
pursuant to Section 3.13 for distribution on such Distribution Date. For
purposes of the preceding sentence, the Monthly Payment on each Balloon Loan
with a delinquent Balloon Payment is equal to the assumed monthly payment that
would have been due on the related Due Date based on the original principal
amortization schedule for such Balloon Loan.

                On or before 1:00 p.m. New York time on the Servicer Remittance
Date, the Servicer shall remit in immediately available funds to the Trustee for
deposit in the Distribution Account an amount equal to the aggregate amount of
Advances, if any, to be made in respect of the Mortgage Loans for the related
Distribution Date either (i) from its own funds, (ii) from the Collection
Account, to the extent of funds held therein for future distribution (in which
case it will cause to be made an appropriate entry in the records of the
Collection Account that amounts held for future distribution have been, as
permitted by this Section 4.07, used by the Servicer in discharge of any such
Advance) or (iii) in the form of any combination of (i) and (ii) aggregating the
total amount of Advances to be made by the Servicer with respect to the Mortgage
Loans. Any amounts held for future distribution and so used shall be
appropriately reflected in the Servicer's records and replaced by the Servicer
by deposit in the Collection Account on or before any future Servicer Remittance
Date to the extent that the Available Funds for the related Distribution Date
(determined without regard to Advances to be made on the Servicer Remittance
Date) shall be less than the total amount that would be distributed to the
Classes of Certificateholders pursuant to Section 4.01 and 4.02 on such
Distribution Date if such amounts held for future distributions had not been so
used to make Advances. The Trustee will provide notice to the Servicer and NIMS
Insurer by telecopy by the close of business on any Servicer Remittance Date in
the event that the amount remitted by the Servicer to the Trustee on such date
is less than the Advances required to be made by the Servicer for the related
Distribution Date, as set forth in the related Remittance Report.

                (c) The obligation of the Servicer to make such Advances is
mandatory, notwithstanding any other provision of this Agreement but subject to
(d) below, and, with respect to any Mortgage Loan, shall continue until the
earlier of such time as the Trust acquires title to the related Mortgaged
Property or such Mortgage Loan is paid in full by the Mortgagor or disposed of
by the Trust, or until the recovery of all Liquidation Proceeds thereon.

                (d) Notwithstanding anything herein to the contrary, no Advance
or Servicing Advance shall be required to be made hereunder by the Servicer if
such Advance would, if made, constitute a Nonrecoverable Advance. The
determination by the Servicer that it has made a Nonrecoverable Advance or that
any proposed Advance, if made, would constitute a Nonrecoverable Advance, shall
be evidenced by an Officers' Certificate of the Servicer delivered to the
Depositor, the NIMS Insurer and the Trustee. The Trustee shall be entitled to
conclusively rely upon any such determination by the Servicer.

        for REMIC 2 Regular Interests with the same numerical denomination, such
        payments of principal shall be allocated pro rata between such REMIC 2
        Regular Interests.

                    (3) On each Distribution Date, the Trustee shall cause in
the following order of priority, the following amounts to be distributed by

        aggregate Principal Balance of the Mortgage Loans in the related Loan
        Group over (y) the aggregate current Certificate Principal Balances of
        the Class A Certificates in the related group of Mortgage Loans (except
        that if any such excess is a larger number than in the preceding
        distribution period, the least amount of Realized Losses shall be
        applied to such REMIC 3 Regular Interests such that the REMIC 3
        Subordinated Balance Ratio is maintained); and third, any remaining
        Realized Losses shall be allocated to REMIC 3 Regular Interest LT1XX;
        and

                (xi) All Realized Losses on the Class CE Interest in respect of
        REMIC 4 shall be allocated shall be allocated by the Trustee on each
        Distribution Date to REMIC 5 and the Class CE Certificates.

                (g) Notwithstanding anything to the contrary contained herein,
the above distributions in this Section 4.08 (other than on the Certificates)
are deemed distributions, and distributions of funds from the Distribution
Account shall be made only in accordance with Sections 4.01 and 4.02 hereof.

                Section 4.09   Swap Account.

                (a) No later than the Closing Date, the Trustee shall establish
and maintain a separate, segregated trust account to be titled, "Wells Fargo
Bank, N.A. as Trustee, in trust for the registered holders of Asset Backed
Funding Corporation Asset-Backed Certificates, Series 2006-OPT1--Swap Account."
Such account shall be an Eligible Account and funds on deposit therein shall be
held separate and apart from, and shall not be commingled with, any other
moneys, including, without limitation, other moneys of the Trustee held pursuant
to this Agreement. Amounts therein shall be held uninvested.

                (b) On the Business Day prior to each Distribution Date, prior
to any distribution to any Certificate, the Trustee shall deposit into the Swap
Account: (i) the amount of any Net Swap Payment or Swap Termination Payment
(other than any Swap Termination Payment resulting from a Swap Provider Trigger
Event) owed to the Swap Provider (after taking into account any upfront payment
received from the counterparty to a replacement interest rate swap agreement)
from Available Funds and (ii) amounts received by the Trustee, for distribution
in accordance with Section 4.02(c). For federal income tax purposes, any amounts
paid to the Swap Provider on the Business Day prior to each Distribution Date
shall be deemed paid, pursuant to Section 4.08 hereof (i) from REMIC 1 to REMIC
2, pro rata to the REMIC 1 Regular Interests based on the Uncertificated Accrued
Interest thereon, (ii) then from REMIC 2 to REMIC 3 , pro rata to the REMIC 2
Regular Interests based on Uncertificated Accrued Interest thereon, (iii) then
from REMIC 3 to REMIC 4 in respect of the Class LTIO Interest, (iv) then from
REMIC 4 to REMIC 5 in respect of the Swap IO Interest, and (v) then from the
Class CE Certificates to the Swap Provider in respect of the Net Swap Payment
due to the Swap Provider on such Distribution Date. To the extent the payment
provided for in the preceding sentence is less than the amount of the Net Swap
Payment due to the Swap Provider on such Distribution Date, such additional
amounts shall be deemed paid in a manner similar to the deemed payments provided
in the preceding sentence to the Holders of the Offered Certificates and the
Class B Certificates in respect of the Class IO Distribution Amount (as defined
in Section 4.09(d) below), and then shall be deemed paid to the Class CE
Certificates pursuant to the notional principal contract described in Section
4.09(d) below and then to the Swap Provider. Any amounts deemed paid by any
REMIC created hereunder pursuant to the preceding two sentences shall not be
duplicated by any payments deemed made pursuant to Section 4.08 on the
succeeding Distribution Date. Any Swap Termination Payment triggered by a Swap
Provider Trigger Event owed to the Swap Provider pursuant to the Interest Rate
Swap Agreement will be subordinated to distributions to the Holders of the Class
A Certificates, Class B Certificates, and Class M Certificates and shall be paid
as set forth under Section 4.02(b)(xxxiv).

                (c) For federal income tax purposes, the Swap Account shall be
owned by the Holders of the Class CE Certificates.

                (d) The Trustee shall treat the Holders of Certificates (other
than the Class P, Class CE and Residual Certificates) as having entered into a
notional principal contract with respect to the Holders of the Class CE
Certificates. Pursuant to each such notional principal contract, all Holders of
Certificates (other than the Class P, Class CE and Residual Certificates) shall
be treated as having agreed to pay, on each Distribution Date, to the Holder of
the Class CE Certificates an aggregate amount equal to the excess, if any, of
(i) the amount payable on such Distribution Date on the Regular Interest in
REMIC 4 corresponding to such Class of Certificates over (ii) the amount payable
on such Class of Certificates on such Distribution Date (such excess, a "Class
IO Distribution Amount"). A Class IO Distribution Amount payable from interest
collections shall be allocated pro rata among such Certificates based on the
excess of (a) the amount of interest otherwise payable to such Certificates over
(ii) the amount of interest payable to such Certificates at a per annum rate
equal to the applicable Cap, and a Class IO Distribution Amount payable from
principal collections shall be allocated to the most subordinate Class of
Certificates with an outstanding principal balance to the extent of such
balance. In addition, pursuant to such notional principal contract, the Holders
of the Class CE Certificates shall be treated as having agreed to pay Cap
Carryover Amounts to the Holders of the Certificates (other than the Class CE,
Class P and Residual Certificates), in accordance with the terms of this
Agreement. Any payments to the Certificates from amounts deemed received in
respect of this notional principal contract shall not be payments with respect
to a Regular Interest in a REMIC within the meaning of Code Section 860G(a)(1).
However, any payment from the Certificates (other than the Class CE, Class P and
Residual Certificates) of a Class IO Distribution Amount shall be treated for
tax purposes as having been received by the Holders of such Certificates in
respect of their interests in REMIC 4 and as having been paid by such Holders to
the Trustee pursuant to the notional principal contract. Thus, each Certificate
(other than the Class P and Residual Certificates) shall be treated as
representing not only ownership of Regular Interests in REMIC 4, but also
ownership of an interest in, and obligations with respect to, a notional
principal contract.

                Section 4.10   Group 3 Pre-Funding Account.

                (a) No later than the Closing Date, the Trustee shall establish
and maintain a segregated trust account that is an Eligible Account, which shall
be titled "Group 3 Pre-Funding Account, Wells Fargo Bank, N.A., as trustee, in
trust for the registered Holders of ABFC 2006-OPT1 Trust, Asset Backed Funding
Corporation Asset-Backed Certificates, Series 2006-OPT1" (the "Group 3
Pre-Funding Account"). The Trustee shall, promptly upon receipt, deposit in the
Group 3 Pre-Funding Account and retain therein the Original Group 3 Pre-Funded
Amount remitted on the Closing Date to the Trustee by the Depositor. Funds
deposited in the Group 3 Pre-Funding Account shall be held in trust by the
Trustee for the Certificateholders for the uses and purposes set forth herein.

                (b) Funds in the Group 3 Pre-Funding Account will remain
uninvested. For federal income tax purposes, the Depositor shall be the owner of
Group 3 Pre-Funding Account and shall report all items of income, deduction,
gain or loss arising therefrom.

                (c) Amounts on deposit in the Group 3 Pre-Funding Account shall
be withdrawn by the Trustee as follows:

                (i) On any Additional Transfer Date, the Trustee shall withdraw
        from the Group 3 Pre-Funding Account an amount equal to 100% of the
        aggregate Principal Balance of the Additional Group 3 Mortgage Loans
        transferred and assigned to the Trustee for deposit in the Mortgage Pool
        on such Additional Transfer Date and pay such amount to or upon the
        order of the Depositor upon satisfaction of the conditions set forth in
        Section 2.04 with respect to such transfer and assignment;

                (ii) If the amount on deposit in the Group 3 Pre-Funding Account
        has not been reduced to zero during the Funding Period, on the day
        immediately following the termination of the Funding Period, the Trustee
        shall deposit into the Distribution Account any amounts remaining in the
        Group 3 Pre-Funding Account for distribution in accordance with the
        terms hereof;

                (iii) To withdraw any amount not required to be deposited in the
        Group 3 Pre-Funding Account or deposited therein in error; and

                (iv) To clear and terminate the Group 3 Pre-Funding Account upon
        the earlier to occur of (A) the Distribution Date immediately following
        the end of the Funding Period and (B) the termination of this Agreement,
        with any amounts remaining on deposit therein being paid to the Holders
        of the Certificates then entitled to distributions in respect of
        principal.

                Withdrawals pursuant to clauses (i), (ii) and (iii) shall be
treated as contributions of cash to REMIC 1 on the date of withdrawal.

                Section 4.11   Cap Carryover Reserve Account

                On the Closing Date, the Trustee will establish the Cap
Carryover Reserve Account (the "Cap Carryover Reserve Account"), which account
will remain uninvested, held in trust for the benefit of the Holders of the
Offered Certificates and Class B Certificates. The Cap Carryover Reserve Account
will be an asset of the Trust but not of any REMIC. On each Distribution Date,
Cap Carryover Amounts available pursuant to clause (xxxiii) of Section 4.02(b)
will be deposited into the Cap Carryover Reserve Account. On such Distribution
Date, the Trustee shall withdraw such Cap Carryover Amounts on deposit and apply
them, sequentially, as follows:

                first, concurrently, to the Class A-1, Class A-2, Class A-3A,
Class A-3B, Class A-3C1, Class A-3C2 and Class A-3D Certificates, pro rata
(based on the Cap Carryover Amount for each such Class), any Cap Carryover
Amount for such Class; and

                second, sequentially, to the Class M-1, Class M-2, Class M-3,
Class M-4, Class M-5, Class M-6, Class M-7, Class M-8, Class M-9 and Class B
Certificates, any Cap Carryover Amount for such Class.

                                THE CERTIFICATES

                Section 5.01   The Certificates.

                Each of the Class A-1, Class A-2, Class A-3A, Class A-3B, Class
A-3C1, Class A-3C2, Class A-3D, Class M-1, Class M-2, Class M-3, Class M-4,
Class M-5, Class M-6, Class M-7, Class M-8, Class M-9, Class B, Class CE, Class
P and Residual Certificates shall be substantially in the forms annexed hereto
as exhibits, and shall, on original issue, be executed by the Trustee and
authenticated and delivered by the Certificate Registrar to or upon the receipt
of a Written Order to Authenticate from the Depositor concurrently with the sale
and assignment to the Trustee of the Trust Fund. Each Class of the Offered
Certificates and the Class B Certificates shall be initially evidenced by one or
more Certificates representing a Percentage Interest with a minimum dollar
denomination of $25,000 and integral multiples of $1 in excess thereof. The
Class CE and Class P Certificates are issuable only in minimum Percentage
Interests of 10%. Each Residual Certificate is issuable only as a single
certificate.

                The Certificates shall be executed on behalf of the Trust by
manual or facsimile signature on behalf of the Trustee by a Responsible Officer.
Certificates bearing the manual or facsimile signatures of individuals who were,
at the time when such signatures were affixed, authorized to sign on behalf of
the Trustee shall bind the Trust, notwithstanding that such individuals or any
of them have ceased to be so authorized prior to the authentication and delivery
of such Certificates or did not hold such offices at the date of such
Certificate. No Certificate shall be entitled to any benefit under this
Agreement or be valid for any purpose, unless such Certificate shall have been
manually authenticated by the Certificate Registrar substantially in the form
provided for herein, and such authentication upon any Certificate shall be
conclusive evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication. Subject to Section 5.02(c), the Offered Certificates
and the Class B Certificates shall be Book-Entry Certificates. The Class CE,
Class P and Residual Certificates shall not be Book-Entry Certificates but shall
be issued in fully registered certificate form.

                Section 5.02   Registration of Transfer and Exchange of
Certificates.

                (a) The Certificate Registrar shall cause to be kept at the
Corporate Trust Office of the Trustee a Certificate Register in which, subject
to such reasonable regulations as it may prescribe, the Certificate Registrar
shall provide for the registration of Certificates and of transfers and
exchanges of Certificates as herein provided. The Trustee shall initially serve
as Certificate Registrar for the purpose of registering Certificates and
transfers and exchanges of Certificates as herein provided. The Trustee as
Certificate Registrar shall be subject to the same standards of care,
limitations on liability and rights to indemnity as the Trustee, and the
provisions of Sections 8.01, 8.02, 8.03, 8.04, 8.05, 8.14, 8.15 and 8.16 shall
apply to the Certificate Registrar to the same extent as they apply to the
Trustee. Any Certificate Registrar appointed in accordance with this Section
5.02(a) may at any time resign by giving at least 30 days' advance written
notice of resignation to the Trustee, the Servicer and the Depositor, such
resignation to become effective upon appointment of a successor Certificate
Registrar.

                Upon surrender for registration of transfer of any Certificate
at any office or agency of the Certificate Registrar maintained for such purpose
pursuant to the foregoing paragraph and, in the case of the Residual
Certificates, upon satisfaction of the conditions set forth below, the Trustee
on behalf of the Trust shall execute and the Certificate Registrar shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of the same aggregate Percentage
Interest.

                At the option of the Certificateholders, Certificates may be
exchanged for other Certificates in authorized denominations and the same
aggregate Percentage Interests, upon surrender of the Certificates to be
exchanged at any such office or agency. Whenever any Certificates are so
surrendered for exchange, the Trustee shall execute on behalf of the Trust and
the Certificate Registrar shall authenticate and deliver the Certificates which
the Certificateholder making the exchange is entitled to receive. Every
Certificate presented or surrendered for registration of transfer or exchange
shall (if so required by the Trustee or the Certificate Registrar) be duly
endorsed by, or be accompanied by a written instrument of transfer satisfactory
to the Trustee and the Certificate Registrar duly executed by, the Holder
thereof or his attorney duly authorized in writing.

                (b) Upon original issuance, the Book-Entry Certificates shall be
issued in the form of one or more typewritten certificates, to be delivered to
the Depository, the initial Depository, by, or on behalf of, the Depositor; or
to, and deposited with the Certificate Custodian, on behalf of the Depository,
if directed to do so pursuant to instructions from the Depository. Except as
provided in paragraph (c) below, the Book-Entry Certificates shall at all times
remain registered in the name of the Depository or its nominee and at all times:
(i) registration of such Certificates may not be transferred by the Trustee
except to another Depository; (ii) the Depository shall maintain book-entry
records with respect to the Certificate Owners and with respect to ownership and
transfers of such Certificates; (iii) ownership and transfers of registration of
such Certificates on the books of the Depository shall be governed by applicable
rules established by the Depository; (iv) the Depository may collect its usual
and customary fees, charges and expenses from its Depository Participants; (v)
the Trustee shall for all purposes deal with the Depository as representative of
the Certificate Owners of the Certificates for purposes of exercising the rights
of Holders under this Agreement, and requests and directions for and votes of
such representative shall not be deemed to be inconsistent if they are made with
respect to different Certificate Owners; (vi) the Trustee may rely and shall be
fully protected in relying upon information furnished by the Depository with
respect to its Depository Participants and furnished by the Depository
Participants with respect to indirect participating firms and Persons shown on
the books of such indirect participating firms as direct or indirect Certificate
Owners; and (vii) the direct participants of the Depository shall have no rights
under this Agreement under or with respect to any of the Certificates held on
their behalf by the Depository, and the Depository may be treated by the Trustee
and its agents, employees, officers and directors as the absolute owner of the
Certificates for all purposes whatsoever.

                All transfers by Certificate Owners of Book-Entry Certificates
shall be made in accordance with the procedures established by the Depository
Participant or brokerage firm representing such Certificate Owners. Each
Depository Participant shall only transfer Book-Entry Certificates of
Certificate Owners that it represents or of brokerage firms for which it acts as
agent in accordance with the Depository's normal procedures. The parties hereto
are hereby authorized to execute a Letter of Representations with the Depository
or take such other action as may be necessary or desirable to register a
Book-Entry Certificate to the Depository. In the event of any conflict between
the terms of any such Letter of Representation and this Agreement, the terms of
this Agreement shall control.

                (c) If the Depository advises the Trustee in writing that the
Depository is no longer willing or able to discharge properly its
responsibilities as Depository and the Trustee or the Depositor is unable to
locate a qualified successor. Upon surrender to the Certificate Registrar of the
Book-Entry Certificates by the Depository, accompanied by registration
instructions from the Depository for registration, the Trustee shall, at the
Trust's expense, execute on behalf of the Trust and the Certificate Registrar
shall authenticate definitive, fully registered certificates (the "Definitive
Certificates"). None of the Depositor or the Trustee shall be liable for any
delay in delivery of such instructions and may conclusively rely on, and shall
be protected in relying on, such instructions. Upon the issuance of Definitive
Certificates, the Trustee, the Certificate Registrar, the Servicer, any Paying
Agent and the Depositor shall recognize the Holders of the Definitive
Certificates as Certificateholders hereunder.

                (d) Except with respect to a transfer of the Private
Certificates between or among the Depositor, the Seller, their affiliates or
both, no transfer, sale, pledge or other disposition of any Private Certificate
shall be made unless such disposition is exempt from the registration
requirements of the Securities Act of 1933, as amended (the "1933 Act"), and any
applicable state securities laws or is made in accordance with the 1933 Act and
laws. In the event of any such transfer, (i) unless such transfer is made in
reliance upon Rule 144A (as evidenced by the investment letter delivered to the
Certificate Registrar, in substantially the form attached hereto as Exhibit J-2)
under the 1933 Act, the Certificate Registrar and the Depositor shall require a
written Opinion of Counsel (which may be in-house counsel) acceptable to and in
form and substance reasonably satisfactory to the Certificate Registrar and the
Depositor that such transfer may be made pursuant to an exemption, describing
the applicable exemption and the basis therefor, from the 1933 Act or is being
made pursuant to the 1933 Act, which Opinion of Counsel shall not be an expense
of the Certificate Registrar or the Depositor or (ii) the Certificate Registrar
shall require the transferor to execute a transferor certificate (in
substantially the form attached hereto as Exhibit L) and the transferee to
execute an investment letter (in substantially the form attached hereto as
Exhibit J-1 or J-2 (in the case of the Class P, Class CE or Residual
Certificates) or in the form of Exhibit J-2 (in the case of Class B
Certificates)) acceptable to and in form and substance reasonably satisfactory
to the Depositor and the Certificate Registrar certifying to the Depositor and
the Certificate Registrar the facts surrounding such transfer, which investment
letter shall not be an expense of the Certificate Registrar or the Depositor.
The Holder of a Private Certificate desiring to effect such transfer shall, and
does hereby agree to, indemnify the Certificate Registrar and the Depositor
against any liability that may result if the transfer is not so exempt or is not
made in accordance with such federal and state laws. For purposes of clause (ii)
of this Section 5.02(d) the representations required in any transferor
certificate (substantially in the form of Exhibit L hereto) and any investment
letter (substantially in the form of Exhibit J-2 hereto) shall be deemed to have
made in connection with the transfer of any Private Certificate that is a
Book-Entry Certificate.

                No transfer of an ERISA-Restricted Certificate shall be made
unless the Certificate Registrar shall have received either (i) a representation
from the transferee of such Certificate, acceptable to and in form and substance
satisfactory to the Certificate Registrar and the Depositor (such requirement is
satisfied only by the Certificate Registrar's receipt of a representation letter
from the transferee substantially in the form of Exhibit I hereto, as
appropriate), to the effect that such transferee is not an employee benefit plan
or arrangement subject to Section 406 of ERISA, a plan subject to Section 4975
of the Code or a plan subject to any federal, state or local law ("Similar Law")
materially similar to the foregoing provisions of ERISA or the Code, nor a
person acting on behalf of any such plan or arrangement nor using the assets of
any such plan or arrangement to effect such transfer other than, except in the
case of the Class P Certificates or the Residual Certificates, an insurance
company general account that is eligible for and meets all requirements for
relief under Sections I and III of PTCE 95-60 or (ii) (except in the case of the
Class P Certificates or the Residual Certificates) in the case of any such ERISA
Restricted Certificate presented for registration in the name of an employee
benefit plan subject to ERISA or a plan or arrangement subject to Section 4975
of the Code (or comparable provisions of any subsequent enactments), or a
trustee of any such plan or any other person acting on behalf of any such plan
or arrangement or using such plan's or arrangement's assets, an Opinion of
Counsel satisfactory to the Certificate Registrar, to the effect that the
purchase or holding of such ERISA Restricted Certificate will not constitute or
result in a non-exempt prohibited transaction within the meaning of ERISA,
Section 4975 of the Code or Similar Law and will not subject the Depositor, the
Servicer, the Trustee, the NIMS Insurer or the Certificate Registrar to any
obligation in addition to those expressly undertaken in this Agreement or to any
liability. For purposes of clause (i) of the preceding sentence, such
representation shall be deemed to have been made to the Certificate Registrar by
the acceptance by a Certificate Owner of the beneficial interest in any such
Class of ERISA-Restricted Certificates, unless the Certificate Registrar shall
have received from the transferee an alternative representation acceptable in
form and substance to the Depositor. Notwithstanding anything else to the
contrary herein, any purported transfer of an ERISA-Restricted Certificate to or
on behalf of an employee benefit plan subject to ERISA, Section 4975 of the Code
or Similar Law without the delivery to the Certificate Registrar of an Opinion
of Counsel satisfactory to the Certificate Registrar as described above shall be
void and of no effect.

                For so long as the Interest Rate Swap Agreement is in existence,
each beneficial owner of a Certificate other than an ERISA Restricted
Certificate or any interest therein, shall be deemed to have represented, by
virtue of its acquisition or holding of such Certificate, or interest therein,
that either (i) it is not a Plan or (ii) (A) it is an "accredited investor" (as
defined in Rule 501(a) of Regulation D under the 1933 Act, as amended, and (B)
the acquisition and holding of such Certificate and the separate right to
receive payments from the Swap Account are eligible for the exemptive relief
available under Department of Labor Prohibited Transaction Class Exemption 84-14
(for transactions by independent "qualified professional asset managers"), 91-38
(for transactions by bank collective investment funds), 90-1 (for transactions
by insurance company pooled separate accounts), 95-60 (for transactions by
insurance company general accounts) or 96-23 (for transactions effected by
"in-house asset managers").

                Each Person who has or who acquires any Ownership Interest in a
Residual Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the following provisions and to
have irrevocably appointed the Depositor or its designee as its attorney-in-fact
to negotiate the terms of any mandatory sale under clause (v) below and to
execute all instruments of transfer and to do all other things necessary in
connection with any such sale, and the rights of each Person acquiring any
Ownership Interest in a Residual Certificate are expressly subject to the
following provisions:

                (i) Each Person holding or acquiring any Ownership Interest in a
        Residual Certificate shall be a Permitted Transferee and shall promptly
        notify the Certificate Registrar of any change or impending change in
        its status as a Permitted Transferee.

                (ii) No Person shall acquire an Ownership Interest in a Residual
        Certificate unless such Ownership Interest is a pro rata undivided
        interest.

                (iii) In connection with any proposed transfer of any Ownership
        Interest in a Residual Certificate, the Certificate Registrar shall as a
        condition to registration of the transfer, require delivery to it, in
        form and substance satisfactory to it, of each of the following:

                A. an affidavit in the form of Exhibit K hereto from the
proposed transferee to the effect that, among other things, such transferee is a
Permitted Transferee and that it is not acquiring its Ownership Interest in a
Residual Certificate that is the subject of the proposed transfer as a nominee,
trustee or agent for any Person who is not a Permitted Transferee; and

                B. a covenant of the proposed transferee to the effect that the
proposed transferee agrees to be bound by and to abide by the transfer
restrictions applicable to the Residual Certificates.

                (iv) Any attempted or purported transfer of any Ownership
        Interest in a Residual Certificate in violation of the provisions of
        this Section shall be absolutely null and void and shall vest no rights
        in the purported transferee. If any purported transferee shall, in
        violation of the provisions of this Section, become the Holder of
        Residual Certificate, then the prior Holder of such Residual Certificate
        that is a Permitted Transferee shall, upon discovery that the
        registration of transfer of such Residual Certificate was not in fact
        permitted by this Section, be restored to all rights as Holder thereof
        retroactive to the date of registration of transfer of such Residual
        Certificate. The Certificate Registrar shall be under no liability to
        any Person for any registration of transfer of a Residual Certificate
        that is in fact not permitted by this Section or for making any
        distributions due on such Residual Certificate to the Holder thereof or
        taking any other action with respect to such Holder under the provisions
        of this Agreement so long as the Certificate Registrar received the
        documents specified in clause (iii). The Trustee shall be entitled to
        recover from any Holder of a Residual Certificate that was in fact not a
        Permitted Transferee at the time such distributions were made all
        distributions made on such Residual Certificate. Any such distributions
        so recovered by the Trustee shall be distributed and delivered by the
        Trustee to the prior Holder of such Residual Certificate that is a
        Permitted Transferee.

                (v) If any Person other than a Disqualified Organization
        acquires any Ownership Interest in a Residual Certificate in violation
        of the restrictions in this Section, then the Certificate Registrar
        shall have the right but not the obligation, without notice to the
        Holder of a Residual Certificate or any other Person having an Ownership
        Interest therein, to notify the Depositor to arrange for the sale of a
        Residual Certificate. The proceeds of such sale, net of commissions
        (which may include commissions payable to the Depositor or its
        affiliates in connection with such sale), expenses and taxes due, if
        any, will be remitted by the Trustee to the previous Holder of a
        Residual Certificate that is a Permitted Transferee, except that in the
        event that the Trustee determines that the Holder of a Residual
        Certificate may be liable for any amount due under this Section or any
        other provisions of this Agreement, the Trustee may withhold a
        corresponding amount from such remittance as security for such claim.
        The terms and conditions of any sale under this clause (v) shall be
        determined in the sole discretion of the Trustee and it shall not be
        liable to any Person having an Ownership Interest in a Residual
        Certificate as a result of its exercise of such discretion.

                (vi) If any Person other than a Permitted Transferee acquires
        any Ownership Interest in a Residual Certificate in violation of the
        restrictions in this Section, then the Trustee will provide to the
        Internal Revenue Service, and to the persons specified in Sections
        860E(e)(3) and (6) of the Code, information needed to compute the tax
        imposed under Section 860E(e)(5) of the Code on transfers of residual
        interests to disqualified organizations. The Trustee shall be entitled
        to reasonable compensation for providing such information from the
        person to whom it is provided.

The foregoing provisions of this Section shall cease to apply to transfers
occurring on or after the date on which there shall have been delivered to the
Certificate Registrar, in form and substance satisfactory to the Certificate
Registrar, (i) written notification from each Rating Agency that the removal of
the restrictions on Transfer set forth in this Section will not cause such
Rating Agency to downgrade its rating of the Certificates and (ii) an Opinion of
Counsel to the effect that such removal will not cause any REMIC created
hereunder to fail to qualify as a REMIC.

                (e) No service charge shall be made for any registration of
transfer or exchange of Certificates of any Class, but the Certificate Registrar
may require payment of a sum sufficient to cover any tax or governmental charge
that may be imposed in connection with any transfer or exchange of Certificates.

                All Certificates surrendered for registration of transfer or
exchange shall be cancelled by the Certificate Registrar and disposed of
pursuant to its standard procedures.

                Section 5.03   Mutilated, Destroyed, Lost or Stolen
Certificates.

                If (i) any mutilated Certificate is surrendered to the
Certificate Registrar or the Certificate Registrar receives evidence to its
satisfaction of the destruction, loss or theft of any Certificate and (ii) there
is delivered to the Trustee, the Depositor, the NIMS Insurer and the Certificate
Registrar such security or indemnity as may be required by them to save each of
them harmless, then, in the absence of notice to the Trustee or the Certificate
Registrar that such Certificate has been acquired by a bona fide purchaser, the
Trustee shall execute on behalf of the Trust, and the Certificate Registrar
shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
tenor and Percentage Interest. Upon the issuance of any new Certificate under
this Section, the Trustee or the Certificate Registrar may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto and any other expenses (including the fees and
expenses of the Trustee and the Certificate Registrar) in connection therewith.
Any duplicate Certificate issued pursuant to this Section, shall constitute
complete and indefeasible evidence of ownership in the Trust, as if originally
issued, whether or not the lost, stolen or destroyed Certificate shall be found
at any time.

                Section 5.04   Persons Deemed Owners.

                The Servicer, the Depositor, the NIMS Insurer, the Trustee, the
Certificate Registrar, any Paying Agent and any agent of the Servicer, the
Depositor, the NIMS Insurer, the Certificate Registrar, any Paying Agent or the
Trustee may treat the Person, including a Depository, in whose name any
Certificate is registered as the owner of such Certificate for the purpose of
receiving distributions pursuant to Section 4.01 and 4.02 and for all other
purposes whatsoever, and none of the Servicer, the Trust, the NIMS Insurer, the
Trustee nor any agent of any of them shall be affected by notice to the
contrary.

                Section 5.05   Appointment of Paying Agent.

                (a) The Paying Agent shall make distributions to
Certificateholders from the Distribution Account pursuant to Section 4.01 and
4.02 and shall report the amounts of such distributions to the Trustee. The
duties of the Paying Agent may include the obligation to distribute statements
and provide information to Certificateholders as required hereunder. The Paying
Agent hereunder shall at all times be an entity duly incorporated and validly
existing under the laws of the United States of America or any state thereof,
authorized under such laws to exercise corporate trust powers and subject to
supervision or examination by federal or state authorities. The Paying Agent
shall initially be the Trustee. The Trustee may appoint a successor to act as
Paying Agent, which appointment shall be reasonably satisfactory to the
Depositor, the NIMS Insurer and the Rating Agencies. The Trustee as Paying Agent
shall be subject to the same standards of care, limitations on liability and
rights to indemnity as the Trustee, and the provisions of Sections 8.01, 8.02,
8.03, 8.04, 8.05, 8.14, 8.15 and 8.16 shall apply to the Paying Agent to the
same extent as they apply to the Trustee. Any Paying Agent appointed in
accordance with this Section 5.05 may at any time resign by giving at least 30
days' advance written notice of resignation to the Trustee, the Servicer, the
NIMS Insurer and the Depositor, such resignation to become effective upon
appointment of a successor Paying Agent.

                                   ARTICLE VI

                         THE SERVICER AND THE DEPOSITOR

                Section 6.01   Liability of the Servicer and the Depositor.

                The Servicer shall be liable in accordance herewith only to the
extent of the obligations specifically imposed upon and undertaken by the
Servicer herein. The Depositor shall be liable in accordance herewith only to
the extent of the obligations specifically imposed upon and undertaken by the
Depositor.

                Section 6.02   Merger or Consolidation of, or Assumption of the
Obligations of, the Servicer or the Depositor.

                Any entity into which the Servicer or the Depositor may be
merged or consolidated, or any entity resulting from any merger, conversion or
consolidation to which the Servicer or the Depositor shall be a party, or any
corporation succeeding to the business of the Servicer or the Depositor, shall
be the successor of the Servicer or the Depositor, as the case may be,
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto, anything herein to the contrary
notwithstanding; provided, however, that the successor servicer shall satisfy
all the requirements of Section 7.02 with respect to the qualifications of a
successor servicer. The Servicer and such successor or surviving Person shall
notify the Depositor and the Trustee of any such merger, conversion or
consolidation at least two Business Days prior to the effective date thereof and
shall provide the Depositor and the Trustee with all information required by the
Depositor to comply with its reporting obligation under Item 6.02 of Form 8-K
not later than the effective date of such merger, conversion or consolidation.

                Section 6.03   Limitation on Liability of the Servicer and
Others.

                Neither the Servicer nor any of the directors or officers or
employees or agents of the Servicer shall be under any liability to the Trust or
the Certificateholders for any action taken or for refraining from the taking of
any action by the Servicer in good faith pursuant to this Agreement, or for
errors in judgment; provided, however, that this provision shall not protect the
Servicer or any such Person against any liability which would otherwise be
imposed by reason of its willful misfeasance, bad faith or negligence in the
performance of duties of the Servicer or by reason of its reckless disregard of
its obligations and duties of the Servicer hereunder; provided, further, that
this provision shall not be construed to entitle the Servicer to indemnity in
the event that amounts advanced by the Servicer to retire any senior lien exceed
Liquidation Proceeds (in excess of related liquidation expenses) realized with
respect to the related Mortgage Loan. The Servicer and any director or officer
or employee or agent of the Servicer may rely in good faith on any document of
any kind prima facie properly executed and submitted by any Person respecting
any matters arising hereunder. The Servicer and any director or officer or
employee or agent of the Servicer shall be indemnified by the Trust and held
harmless against any loss, liability or expense incurred in connection with any
legal action relating to this Agreement or the Certificates, other than any
loss, liability or expense incurred by reason of its willful misfeasance, bad
faith or negligence in the performance of duties hereunder or by reason of its
reckless disregard of obligations and duties hereunder. The Servicer may
undertake any such action which it may deem necessary or desirable in respect of
this Agreement, and the rights and duties of the parties hereto and the
interests of the Certificateholders hereunder. In such event, the reasonable
legal expenses and costs of such action and any liability resulting therefrom
shall be expenses, costs and liabilities of the Trust and the Servicer shall be
entitled to pay such expenses from the proceeds of the Trust or to be reimbursed
therefor pursuant to Section 3.05 upon presentation to the Trustee of
documentation of such expenses, costs and liabilities. The Servicer's right to
indemnity or reimbursement pursuant to this Section shall survive any
resignation or termination of the Servicer pursuant to Section 6.04 or 7.01 with
respect to any losses, expenses, costs or liabilities arising prior to such
resignation or termination (or arising from events that occurred prior to such
resignation or termination). This paragraph shall apply to the Servicer solely
in its capacity as Servicer hereunder and in no other capacities.

                Section 6.04   Servicer Not to Resign.

                Subject to the provisions of Section 7.01 and Section 6.02, the
Servicer shall not resign from the obligations and duties hereby imposed on it
except (i) upon determination that the performance of its obligations or duties
hereunder are no longer permissible under applicable law or are in material
conflict by reason of applicable law with any other activities carried on by it
or its subsidiaries or Affiliates, the other activities of the Servicer so
causing such a conflict being of a type and nature carried on by the Servicer or
its subsidiaries or Affiliates at the date of this Agreement or (ii) upon
satisfaction of the following conditions: (a) the Servicer has proposed a
successor servicer to the Trustee and the NIMS Insurer in writing and such
proposed successor servicer is reasonably acceptable to the Trustee and the NIMS
Insurer; and (b) each Rating Agency shall have delivered a letter to the Trustee
and the NIMS Insurer prior to the appointment of the successor servicer stating
that the proposed appointment of such successor servicer as Servicer hereunder
will not result in the reduction or withdrawal of the then current rating of the
Regular Certificates or the ratings that are in effect; provided, however, that
no such resignation by the Servicer shall become effective until such successor
servicer or, in the case of (i) above, the Trustee shall have assumed the
Servicer's responsibilities and obligations hereunder or the Trustee shall have
designated a successor servicer in accordance with Section 7.02. Any such
resignation shall not relieve the Servicer of responsibility for any of the
obligations specified in Sections 7.01 and 7.02 as obligations that survive the
resignation or termination of the Servicer. Any such determination permitting
the resignation of the Servicer shall be evidenced by an Opinion of Counsel to
such effect delivered to the Trustee and the NIMS Insurer.

                Section 6.05   Delegation of Duties.

                (a) In the ordinary course of business, the Servicer, subject to
the provisions of Section 3.16, at any time may delegate any of its duties
hereunder to any Person, including any of its Affiliates, who agrees to conduct
such duties in accordance with standards comparable to those set forth in
Section 3.01. Such delegation shall not relieve the Servicer of its liabilities
and responsibilities with respect to such duties and shall not constitute a
resignation within the meaning of Section 6.04. The Servicer shall provide the
Trustee, the NIMS Insurer and the Rating Agencies with 60 days prior written
notice prior to the delegation of any of its duties to any Person other than any
of the Servicer's Affiliates or their respective successors and assigns.

                (b) The Servicer is hereby authorized, with the consent of the
NIMS Insurer, to enter into a financing or other facility (any such arrangement,
an "Advance Facility") under which (1) the Servicer assigns or pledges to
another Person (together with such Person's successors and assigns, an
"Advancing Person") the Servicer's rights under this Agreement to be reimbursed
for any Advances or Servicing Advances and/or (2) an Advancing Person agrees to
fund some or all Advances and/or Servicing Advances required to be made by the
Servicer pursuant to this Agreement. The Servicer shall notify each other party
to this Agreement prior to or promptly after entering into or terminating any
Advance Facility. Notwithstanding the existence of any Advance Facility under
which an Advancing Person agrees to fund Advances and/or Servicing Advances on
the Servicer's behalf, the Servicer shall remain obligated pursuant to this
Agreement to make Advances and Servicing Advances pursuant to and as required by
this Agreement. If the Servicer enters into an Advance Facility, and for so long
as an Advancing Person remains entitled to receive reimbursement for any
Advances and/or Servicing Advances, as applicable, pursuant to this Agreement,
then the Servicer shall not be permitted to reimburse itself for Advances and/or
Servicing Advances, but instead the Servicer shall be required to remit amounts
collected that would otherwise be retained by the Servicer to reimburse it for
the amount of previously unreimbursed Advances ("Advance Reimbursements") and/or
previously unreimbursed Servicing Advances ("Servicing Advance Reimbursements"
and together with Advance Reimbursements, "Reimbursements") (in each case to the
extent such type of Reimbursements are included in the Advance Facility) in
accordance with the documentation establishing the Advance Facility to such
Advancing Person or to a trustee, agent or custodian (an "Advance Facility
Trustee") designated by such Advancing Person. Notwithstanding anything to the
contrary herein, in no event shall Advance Reimbursements or Servicing Advance
Reimbursements be included in the "Available Funds" or distributed to
Certificateholders. If the terms of a facility proposed to be entered into with
an Advancing Person by the Servicer would not materially and adversely affect
the interests of any Certificateholder, then the NIMS Insurer shall not withhold
its consent to the Servicer's entering such facility.

                Reimbursements shall consist solely of amounts in respect of
Advances and/or Servicing Advances made with respect to the Mortgage Loans for
which the Servicer would be permitted to reimburse itself in accordance with
this Agreement, assuming the Servicer had made the related Advance(s) and/or
Servicing Advance(s). Notwithstanding the foregoing, no Person shall be entitled
to reimbursement from funds held in the Collection Account for future
distribution to Certificateholders pursuant to this Agreement. None of the
Depositor or the Trustee shall have any duty or liability with respect to the
calculation or payment of any Reimbursements, nor shall the Depositor or the
Trustee have any responsibility to track or monitor the administration of the
Advance Facility or the payment of Reimbursements to the related Advancing
Person or Advance Facility Trustee. The Servicer shall maintain and provide to
any successor servicer and (upon request) the Trustee a detailed accounting on a
loan by loan basis as to amounts advanced by, pledged or assigned to, and
reimbursed to any Advancing Person. The successor servicer shall be entitled to
rely on any such information provided by the predecessor servicer, and the
successor servicer shall not be liable for any errors in such information.

                An Advancing Person who receives an assignment or pledge of the
rights to be reimbursed for Advances and/or Servicing Advances, and/or whose
obligations hereunder are limited to the funding of Advances and/or Servicing
Advances shall not be required to meet the criteria for qualification of a
subservicer set forth in this Agreement.

                The documentation establishing any Advance Facility shall
require that Reimbursements distributed with respect to each Mortgage Loan be
allocated to outstanding unreimbursed Advances or Servicing Advances (as the
case may be) made with respect to that Mortgage Loan on a "first in, first out"
(FIFO) basis. Such documentation shall also require the Servicer to provide to
the related Advancing Person or Advance Facility Trustee loan by loan
information with respect to each Reimbursement distributed to such Advancing
Person or Advance Facility Trustee on each Distribution Date, to enable the
Advancing Person or Advance Facility Trustee to make the FIFO allocation of each
Reimbursement with respect to each Mortgage Loan. The Servicer shall remain
entitled to be reimbursed by the Advancing Person or Advance Facility Trustee
for all Advances and Servicing Advances funded by the Servicer to the extent the
related rights to be reimbursed therefor have not been assigned or pledged to an
Advancing Person.

                The Servicer shall indemnify the Depositor, the Trustee, the
NIMS Insurer, any successor servicer and the Trust Fund resulting from any claim
by the related Advancing Person, except to the extent that such claim, loss,
liability or damage resulted from or arose out of negligence, recklessness or
willful misconduct on the part of the Depositor, the Trustee or any successor
servicer.

                Any amendment to this Section 6.05(b) or to any other provision
of this Agreement that may be necessary or appropriate to effect the terms of an
Advance Facility as described generally in this Section 6.05(b), including
amendments to add provisions relating to a successor servicer, may be entered
into by the Trustee, the Depositor and the Servicer without the consent of any
Certificateholder but with the consent of the NIMS Insurer, provided such
amendment complies with Section 11.01 hereof. All reasonable costs and expenses
(including attorneys' fees) of each party hereto of any such amendment shall be
borne solely by the Servicer. Prior to entering into an Advance Facility, the
Servicer shall notify the lender under such facility in writing that: (a) the
Advances and/or Servicing Advances financed by and/or pledged to the lender are
obligations owed to the Servicer on a non-recourse basis payable only from the
cash flows and proceeds received under this Agreement for reimbursement of
Advances and/or Servicing Advances only to the extent provided herein, and the
Trustee and the Trust are not otherwise obligated or liable to repay any
Advances and/or Servicing Advances financed by the lender; (b) the Servicer will
be responsible for remitting to the lender the applicable amounts collected by
it as reimbursement for Advances and/or Servicing Advances funded by the lender,
subject to the restrictions and priorities created in this Agreement; and (c)
the Trustee shall not have any responsibility to track or monitor the
administration of the financing arrangement between the Servicer and the lender.

                If the Servicer determines any such affiliate or third party
vendor would be a "servicer" within the meaning of Item 1101 of Regulation AB,
the Servicer shall not engage such affiliate or third party vendor unless it
provides the Trustee and the Depositor the information required by Section
1108(b) and 1108(c) of Regulation AB prior to such engagement.

                In the event of any assignment of rights or delegation of duties
of the Servicer, the Trustee shall report such event on Form 8-K within four
Business Days after the effective date thereof provided that the Servicer
provides notice of such occurrence to the Trustee within 2 days of such
effective date.

                                  ARTICLE VII

                                     DEFAULT

                Section 7.01   Servicer Events of Termination.

                (i) (A) The failure by the Servicer to make any Advance or to
        pay Compensating Interest; or (B) any other failure by the Servicer to
        deposit in the Collection Account or remit to the Trustee for deposit in
        the Distribution Account any payment required to be made under the terms
        of this Agreement, which failure continues unremedied for a period of
        one Business Day after the first date on which (x) the Servicer has
        knowledge of such failure or (y) written notice of such failure is given
        to the Servicer; or

                (ii) The failure by the Servicer to make any required Servicing
        Advance which failure continues unremedied for a period of 30 days, or
        the failure by the Servicer duly to observe or perform, in any material

        as set forth in this Agreement, which failure continues unremedied for a
        period of 30 days, after the date (A) on which written notice of such
        failure, requiring the same to be remedied, shall have been given to the
        Servicer by the Trustee or the NIMS Insurer or by any Holder of a
        Regular Certificate evidencing at least 25% of the Voting Rights or (B)
        actual knowledge of such failure by a Servicing Officer of the Servicer;
        or

                (iii) The entry against the Servicer of a decree or order by a
        court or agency or supervisory authority having jurisdiction in the
        premises for the appointment of a trustee, conservator, receiver or
        liquidator in any insolvency, conservatorship, receivership,

        proceedings, or for the winding up or liquidation of its affairs, and
        the continuance of any such decree or order unstayed and in effect for a
        period of 60 days; or

                (iv) The Servicer shall voluntarily go into liquidation, consent
        to the appointment of a conservator or receiver or liquidator or similar
        person in any insolvency, readjustment of debt, marshalling of assets
        and liabilities or similar proceedings of or relating to the Servicer or
        of or relating to all or substantially all of its property; or a decree
        or order of a court or agency or supervisory authority having
        jurisdiction in the premises for the appointment of a conservator,
        receiver, liquidator or similar person in any insolvency, readjustment
        of debt, marshalling of assets and liabilities or similar proceedings,
        or for the winding-up or liquidation of its affairs, shall have been
        entered against the Servicer and such decree or order shall have
        remained in force undischarged, unbonded or unstayed for a period of 60
        days; or the Servicer shall admit in writing its inability to pay its
        debts generally as they become due, file a petition to take advantage of
        any applicable insolvency or reorganization statute, make an assignment
        for the benefit of its creditors or voluntarily suspend payment of its
        obligations;

                (v) As of any Distribution Date, if the average for the related
        Collection Period and the two preceding Collection Periods of the
        fraction, expressed as a percentage, the numerator of which is (a) the
        aggregate Principal Balance of 60+ Day Delinquent Loans and the
        denominator of which is (b) the aggregate Principal Balance of the
        Mortgage Loans, in the case of both (a) and (b), as of the last day of
        each such Collection Period, exceeds 18%; or

                (vi) The failure of the Servicer to comply with Sections 3.19,
        3.20 or 3.31 hereof (including with respect to any Additional Servicer,
        Subservicer or Subcontractor engaged by the Servicer) (without any
        regard to any cure period).

                (b) Then, and in each and every such case, so long as a Servicer
Event of Termination shall not have been remedied within the applicable grace
period, (x) with respect solely to clause (i)(A) above, if such Advance is not
made by 2:00 P.M., New York time, on the Business Day immediately following the
Servicer Remittance Date, the Trustee may terminate all of the rights and
obligations of the Servicer under this Agreement and the Trustee, or a successor
servicer appointed in accordance with Section 7.02, shall immediately make such
Advance and assume, pursuant to Section 7.02, the duties of a successor servicer
and (y) in the case of (i)(B), (ii), (iii), (iv), (v) and (vi) above, the
Trustee shall, at the direction of the NIMS Insurer or Holders of each Class of
Regular Certificates evidencing Percentage Interests aggregating not less than
51%, by notice then given in writing to the Servicer (and to the Trustee if
given by Holders of Certificates), terminate all of the rights and obligations
of the Servicer as servicer under this Agreement. Any such notice to the
Servicer shall also be given to each Rating Agency, the NIMS Insurer and the
Depositor. On or after the receipt by the Servicer (and by the Trustee if such
notice is given by the Holders) of such written notice, all authority and power
of the Servicer under this Agreement, whether with respect to the Certificates
or the Mortgage Loans or otherwise, shall pass to and be vested in the Trustee
pursuant to and under this Section or successor servicer appointed in connection
with Section 7.02; and, without limitation, the Trustee or successor servicer is
hereby authorized and empowered to execute and deliver, on behalf of the
Servicer, as attorney-in-fact or otherwise, any and all documents and other
instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement of each Mortgage Loan and Related
Documents or otherwise. The Servicer agrees to cooperate with the Trustee (or
the applicable successor servicer) in effecting the termination of the
responsibilities and rights of the Servicer hereunder, including, without
limitation, the delivery to the Trustee (or the applicable successor servicer)
of all documents and records requested by it to enable it to assume the
Servicer's functions under this Agreement within ten Business Days subsequent to
such notice, the transfer within one Business Day subsequent to such notice to
the Trustee (or the applicable successor servicer) for the administration by it
of all cash amounts that shall at the time be held by the Servicer and to be
deposited by it in the Collection Account, the Distribution Account or any
Escrow Account or that have been deposited by the Servicer in such accounts or
thereafter received by the Servicer with respect to the Mortgage Loans or any
REO Property received by the Servicer. All reasonable out-of-pocket costs and
expenses (including attorneys' fees) incurred in connection with transferring
the servicing to the successor servicer and amending this Agreement to reflect
such succession as Servicer pursuant to this Section shall be paid by the
predecessor servicer (or if the predecessor servicer is the Trustee, the initial
servicer) upon presentation of reasonable documentation of such costs and
expenses, and if such predecessor Servicer defaults in its obligation to pay
such costs, such costs shall be paid by the successor Servicer or the Trustee
(in which case the successor Servicer or the Trustee shall be entitled to
reimbursement therefor from the assets of the Trust).

                Notwithstanding any termination of the activities of a Servicer
hereunder, the Servicer shall be entitled to receive payment of all accrued and
unpaid Servicing Fees and reimbursement for all outstanding Advances and
Servicing Advances properly made prior to the date of termination.

                Section 7.02   Trustee to Act; Appointment of Successor.

                (a) Within 90 days of the time the Servicer (and the Trustee, if
notice is sent by the Holders) receives a notice of termination pursuant to
Section 7.01 or 6.04, the Trustee (or such other successor servicer as is
approved in accordance with this Agreement) shall be the successor in all
respects to the Servicer in its capacity as servicer under this Agreement and
the transactions set forth or provided for herein and shall be subject to all
the responsibilities, duties and liabilities relating thereto placed on the
Servicer by the terms and provisions hereof arising on and after its succession.
As compensation therefor, the Trustee (or such other successor servicer) shall
be entitled to such compensation as the Servicer would have been entitled to
hereunder if no such notice of termination had been given. Notwithstanding the
above, (i) if the Trustee is unwilling to act as successor servicer or (ii) if
the Trustee is legally unable so to act, the Trustee shall appoint or petition a
court of competent jurisdiction to appoint, any established housing and home
finance institution, bank or other mortgage loan or home equity loan servicer
having a net worth of not less than $50,000,000 as the successor to the Servicer
hereunder in the assumption of all or any part of the responsibilities, duties
or liabilities of the Servicer hereunder; provided, that the appointment of any
such successor servicer will not result in the qualification, reduction or
withdrawal of the ratings assigned to the Certificates or the ratings that are
in effect by the Rating Agencies as evidenced by a letter to such effect from
the Rating Agencies and that, in the case of a successor servicer appointed by
the Trustee, such successor servicer is reasonably acceptable to the NIMS
Insurer. Pending appointment of a successor to the Servicer hereunder, unless
the Trustee is prohibited by law from so acting, the Trustee shall act in such
capacity as hereinabove provided. In connection with such appointment and
assumption, the successor shall be entitled to receive compensation out of
payments on Mortgage Loans in an amount equal to the compensation which the
Servicer would otherwise have received pursuant to Section 3.18 (or such other
compensation as the Trustee and such successor shall agree, not to exceed the
Servicing Fee). The successor servicer shall be entitled to withdraw from the
Collection Account all costs and expenses associated with the transfer of the
servicing to the successor servicer, including costs and expenses of the
Trustee. The appointment of a successor servicer shall not affect any liability
of the predecessor servicer which may have arisen under this Agreement prior to
its termination as Servicer to pay any deductible under an insurance policy
pursuant to Section 3.11 or to indemnify the parties indicated in Section 3.26
pursuant to the terms thereof, nor shall any successor servicer be liable for
any acts or omissions of the predecessor servicer or for any breach by such
servicer of any of its representations or warranties contained herein or in any
related document or agreement. The Trustee and such successor shall take such
action, consistent with this Agreement, as shall be necessary to effectuate any
such succession.

                (b) Any successor, including the Trustee, to the Servicer as
servicer shall during the term of its service as servicer continue to service
and administer the Mortgage Loans for the benefit of Certificateholders, and
maintain in force a policy or policies of insurance covering errors and
omissions in the performance of its obligations as Servicer hereunder and a
Fidelity Bond in respect of its officers, employees and agents to the same
extent as the Servicer is so required pursuant to Section 3.12.

                (c) The predecessor Servicer and successor Servicer shall notify
the Depositor and Trustee of any such appointment at least two Business Days
prior to the effective date thereof and shall provide the Depositor and the
Trustee with all information required by the Depositor to comply with its
reporting obligation under Item 6.02 of Form 8-K not later than the effective
date of such appointment.

                Section 7.03   Waiver of Defaults.

                The Holders of Certificates entitled to at least 66 2/3% of the
Voting Rights allocated to the Classes of Certificates affected by a Servicer
Event of Termination may, on behalf of all Certificateholders, and with the
consent of the NIMS Insurer, waive any events permitting removal of the Servicer
as servicer pursuant to this Article VII, provided, however, that such Holders
may not waive a default in making a required distribution on a Certificate
without the consent of the Holder of such Certificate and the NIMS Insurer. Upon
any waiver of a past default, such default shall cease to exist and any Servicer
Event of Termination arising therefrom shall be deemed to have been remedied for
every purpose of this Agreement. No such waiver shall extend to any subsequent
or other default or impair any right consequent thereto except to the extent
expressly so waived. Notice of any such waiver shall be given by the Trustee to
the Rating Agencies.

                Section 7.04   Notification to Certificateholders.

                (a) On any termination or appointment of a successor to the
Servicer pursuant to this Article VII or Section 6.04, the Trustee shall give
prompt written notice thereof to the Certificateholders at their respective
addresses appearing in the Certificate Register, the NIMS Insurer and each
Rating Agency.

                (b) No later than 60 days after the occurrence of any event
which constitutes or which, with notice or a lapse of time or both, would
constitute a Servicer Event of Termination for five Business Days after a
Responsible Officer of the Trustee becomes aware of the occurrence of such an
event, the Trustee shall transmit by mail to the NIMS Insurer and all
Certificateholders notice of such occurrence unless such default or Servicer
Event of Termination shall have been waived or cured. Such notice shall be given
to the Rating Agencies promptly after any such occurrence.

                Section 7.05   Survivability of Servicer Liabilities.

                Notwithstanding anything herein to the contrary, upon
termination of the Servicer hereunder, any liabilities of the Servicer which
accrued prior to such termination shall survive such termination.

                                  ARTICLE VIII

                                   THE TRUSTEE

                Section 8.01   Duties of Trustee.

                (a) The Trustee, prior to the occurrence of a Servicer Event of
Termination of which a Responsible Officer of the Trustee shall have actual
knowledge and after the curing of all Servicer Events of Termination which may
have occurred, undertakes to perform such duties and only such duties as are
specifically set forth in this Agreement. If a Servicer Event of Termination has
occurred (which has not been cured) of which a Responsible Officer has actual
knowledge, the Trustee shall exercise such of the rights and powers vested in it
by this Agreement, and use the same degree of care and skill in their exercise,
as a prudent person would exercise or use under the circumstances in the conduct
of such person's own affairs.

                The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they
conform to the requirements of this Agreement; provided, however, that the
Trustee shall not be responsible for the accuracy or content of any resolution,
certificate, statement, opinion, report, document, order or other instrument
furnished by the Servicer, the Seller, the NIMS Insurer or the Depositor
hereunder. If any such instrument is found not to conform in any material
respect to the requirements of this Agreement, the Trustee shall notify the
Certificateholders of such instrument in the event that the Trustee, after so
requesting, does not receive a satisfactorily corrected instrument.

                No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own misconduct; provided, however, that:

                (i) prior to the occurrence of a Servicer Event of Termination
        of which a Responsible Officer of the Trustee shall have actual
        knowledge, and after the curing of all such Servicer Events of
        Termination which may have occurred, the duties and obligations of the
        Trustee shall be determined solely by the express provisions of this
        Agreement, the Trustee shall not be liable except for the performance of
        such duties and obligations as are specifically set forth in this
        Agreement, no implied covenants or obligations shall be read into this
        Agreement against the Trustee and, in the absence of bad faith on the
        part of the Trustee, the Trustee may conclusively rely, as to the truth
        of the statements and the correctness of the opinions expressed therein,
        upon any certificates or opinions furnished to the Trustee and
        conforming to the requirements of this Agreement;

                (ii) the Trustee shall not be personally liable for an error of
        judgment made in good faith by a Responsible Officer of the Trustee,
        unless it shall be proved that the Trustee was negligent in ascertaining
        or investigating the facts related thereto;

                (iii) the Trustee shall not be personally liable with respect to
        any action taken, suffered or omitted to be taken by it in good faith in
        accordance with the direction of the NIMS Insurer or the Majority
        Certificateholders relating to the time, method and place of conducting
        any proceeding for any remedy available to the Trustee or exercising or
        omitting to exercise any trust or power conferred upon the Trustee under
        this Agreement; and

                (iv) the Trustee shall not be charged with knowledge of any
        failure by the Servicer to comply with the obligations of the Servicer
        referred to in clauses (i) and (ii) of Section 7.01(a) or any Servicer
        Event of Termination unless a Responsible Officer of the Trustee at the
        Corporate Trust Office obtains actual knowledge of such failure or the
        Trustee receives written notice of such failure from the Servicer, the
        NIMS Insurer or the Majority Certificateholders. In the absence of such
        receipt of such notice, the Trustee may conclusively assume that there
        is no Servicer Event of Termination.

                The Trustee shall not be required to expend or risk its own
funds or otherwise incur financial liability in the performance of any of its
duties hereunder, or in the exercise of any of its rights or powers, if there is
reasonable ground for believing that the repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it, and
none of the provisions contained in this Agreement shall in any event require
the Trustee to perform, or be responsible for the manner of performance of, any
of the obligations of the Servicer under this Agreement, except during such
time, if any, as the Trustee shall be the successor to, and be vested with the
rights, duties, powers and privileges of, the Servicer in accordance with the
terms of this Agreement.

                The Trustee shall not have any duty (A) to see to any recording,
filing, or depositing of this Agreement or any agreement referred to herein or
any financing statement or continuation statement evidencing a security
interest, or to see to the maintenance of any such recording or filing or
depositing or to any rerecording, refiling or redepositing of any thereof, (B)
to see to any insurance or (C) to see to the payment or discharge of any tax,
assessment, or other governmental charge or any lien or encumbrance of any kind
owing with respect to, assessed or levied against, any part of the Trust Fund
other than from funds available in the Distribution Account.

                (b) Upon its receipt from the Sponsor of the "significance
estimate" of the Interest Rate Swap Agreement provided in accordance with the
Mortgage Loan Purchase Agreement, the Trustee shall, on the basis of each such
"significance estimate," calculate the Interest Rate Swap Agreement's
"significance percentage" of the of the Pool Balance as of the date of such
"significance estimate" in accordance with Item 1115 of Regulation AB. For the
avoidance of doubt, such "significance percentage" shall be a fraction,
expressed as a percentage, the numerator of which is such "significance
estimate" and the denominator of which is the Pool Balance. Further, the Trustee
shall determine as of such date whether such "significance percentage" would
require disclosure of financial information with respect to the Swap Provider in
any report required to be filed with the Commission pursuant to Section 3.31,
and if it does, the Trustee shall make a written request of the Swap Provider
for such information in accordance with the Interest Rate Swap Agreement, not
later than the Business Day following the Business Day on which it receives the
related "significance estimate." Upon its receipt of such information, the
Trustee shall furnish such information to the Depositor and, if such information
is approved by the Depositor, shall include such information in the related
report as provided in Section 3.31. In the event the Trustee does not timely
receive such information it shall promptly notify the Depositor.

                With respect to the failure of the Swap Provider to perform any
of its obligations under the Interest Rate Swap Agreement, the breach by the
Swap Provider of any of its representations and warranties made pursuant to the
Interest Rate Swap Agreement, or the termination of the Interest Rate Swap
Agreement, the Trustee shall send any notices and make any demands, on behalf of
the Trust, as are required under the Interest Rate Swap Agreement. The Trustee
shall cause any replacement swap provider to provide a copy of the related
replacement interest rate swap agreement to the Trustee and the Depositor.

                Upon the occurrence of a Swap Early Termination (i) to the
extent that the Trustee receives a Swap Termination Payment from the Swap
Provider, if the Trustee acquires a replacement interest rate swap agreement,
the Trustee shall apply all or a portion of such Swap Termination Payment as may
be necessary to acquire a replacement swap provider under the replacement
interest rate swap agreement prior to distribution of such Swap Termination
Payment in accordance with the priorities set forth in this Agreement and (ii)
to the extent that a Swap Termination Payment is owed to the Swap Provider, if
the Trustee acquires a replacement interest rate swap agreement, the Trustee
shall apply all or a portion of the amount received from any replacement swap
provider under a replacement interest rate swap agreement to pay the Swap
Termination Payment owed to the Swap Provider.

                (c) Subject to the conditions set forth in this Section 8.01(c),
the Trustee is permitted to utilize one or more Subcontractors to perform
certain of its obligations hereunder. The Trustee shall promptly upon request
provide to the Depositor a written description (in form and substance
satisfactory to the Depositor) of the role and function of each Subcontractor
utilized by the Trustee, specifying (i) the identity of each such Subcontractor
that is a Servicing Function Participant and (ii) which elements of the
Servicing Criteria will be addressed in Assessments of Compliance provided by
each Servicing Function Participant. As a condition to the utilization by the
Trustee of any Servicing Function Participant, the Trustee shall cause any such
Servicing Function Participant for the benefit of the Depositor to comply with
the provisions of Sections 3.20 and 3.31 of this Agreement to the same extent as
if such Servicing Function Participant were the Trustee. The Trustee shall be
responsible for obtaining from each such Servicing Function Participant and
delivering to the applicable Persons any Assessment of Compliance and related
Attestation Report required to be delivered by such Servicing Function
Participant under Section 3.31, in each case as and when required to be
delivered.

                Notwithstanding the foregoing, if the Trustee engages a
Subcontractor in connection with the performance of any of its duties under this
Agreement, the Trustee shall be responsible for determining whether such
Subcontractor is an Additional Servicer.

                The Trustee shall indemnify the Depositor and the Sponsor and
any of their directors, officers, employees or agents and hold them harmless
against any and all claims, losses, damages, penalties, fines, forfeitures,
reasonable and necessary legal fees and related costs, judgments, and any other
costs, fees and expenses that any of them may sustain in any way related to a
breach of the Trustee's obligation set forth in Section 8.01(b) or 8.01(c).

                Section 8.02   Certain Matters Affecting the Trustee.

                (a) Except as otherwise provided in Section 8.01:

                (i) the Trustee may request and rely upon, and shall be
        protected in acting or refraining from acting upon, any resolution,
        Officer's Certificate, certificate of auditors or any other certificate,
        statement, instrument, opinion, report, notice, request, consent, order,
        appraisal, bond or other paper or document reasonably believed by it to
        be genuine and to have been signed or presented by the proper party or
        parties;

                (ii) the Trustee may consult with counsel and any advice or
        Opinion of Counsel shall be full and complete authorization and
        protection in respect of any action taken or suffered or omitted by it
        hereunder in good faith and in accordance with such advice or Opinion of
        Counsel;

                (iii) the Trustee shall not be under any obligation to exercise
        any of the rights or powers vested in it by this Agreement, or to
        institute, conduct or defend any litigation hereunder or in relation
        hereto, at the request, order or direction of the Certificateholders or
        the NIMS Insurer pursuant to the provisions of this Agreement, unless
        such Certificateholders or the NIMS Insurer shall have offered to the
        Trustee reasonable security or indemnity against the costs, expenses and
        liabilities which may be incurred therein or thereby; the right of the
        Trustee to perform any discretionary act enumerated in this Agreement
        shall not be construed as a duty, and the Trustee shall not be
        answerable for other than its negligence or willful misconduct in the
        performance of any such act;

                (iv) the Trustee shall not be personally liable for any action
        taken, suffered or omitted by it in good faith and believed by it to be
        authorized or within the discretion or rights or powers conferred upon
        it by this Agreement;

                (v) prior to the occurrence of a Servicer Event of Termination
        and after the curing of all Servicer Events of Termination which may
        have occurred, the Trustee shall not be bound to make any investigation
        into the facts or matters stated in any resolution, certificate,
        statement, instrument, opinion, report, notice, request, consent, order,
        approval, bond or other paper or documents, unless requested in writing
        to do so by the Majority Certificateholders or the NIMS Insurer;
        provided, however, that if the payment within a reasonable time to the
        Trustee of the costs, expenses or liabilities likely to be incurred by
        it in the making of such investigation is, in the opinion of the
        Trustee, not reasonably assured to the Trustee by the security afforded
        to it by the terms of this Agreement, the Trustee may require reasonable
        indemnity against such cost, expense or liability as a condition to such
        proceeding. The reasonable expense of every such examination shall be
        paid by the Servicer or, if paid by the Trustee, shall be reimbursed by
        the Servicer upon demand. Nothing in this clause (v) shall derogate from
        the obligation of the Servicer to observe any applicable law prohibiting
        disclosure of information regarding the Mortgagors;

                (vi) the Trustee shall not be accountable, have any liability or
        make any representation as to any acts or omissions hereunder of the
        Servicer until such time as the Trustee may be required to act as
        Servicer pursuant to Section 7.02;

                (vii) the Trustee may execute any of the trusts or powers
        hereunder or perform any duties hereunder either directly or by or
        through agents or attorneys or a custodian and the Trustee shall not be
        responsible for any misconduct or negligence on the part of any such
        agent, attorney or custodian appointed by it with due care; and

                (viii) the right of the Trustee to perform any discretionary act
        enumerated in this Agreement shall not be construed as a duty, and the
        Trustee shall not be answerable for other than its negligence or willful
        misconduct in the performance of such act.

                Section 8.03   Trustee Not Liable for Certificates or Mortgage
Loans.

                The recitals contained herein and in the Certificates (other
than the authentication of the Trustee on the Certificates) shall be taken as
the statements of the Depositor, and the Trustee assumes no responsibility for
the correctness of the same. The Trustee makes no representations as to the
validity or sufficiency of this Agreement or of the Certificates (other than the
signature and authentication of the Trustee on the Certificates) or of any
Mortgage Loan or Related Document. The Trustee shall not be accountable for the
use or application by the Servicer, or for the use or application of any funds
paid to the Servicer in respect of the Mortgage Loans or deposited in or
withdrawn from the Collection Account by the Servicer. The Trustee shall not at
any time have any responsibility or liability for or with respect to the
legality, validity and enforceability of any Mortgage or any Mortgage Loan, or
the perfection and priority of any Mortgage or the maintenance of any such
perfection and priority, or for or with respect to the sufficiency of the Trust
or its ability to generate the payments to be distributed to Certificateholders
under this Agreement, including, without limitation: the existence, condition
and ownership of any Mortgaged Property; the existence and enforceability of any
hazard insurance thereon (other than if the Trustee shall assume the duties of
the Servicer pursuant to Section 7.02); the validity of the assignment of any
Mortgage Loan to the Trustee or of any intervening assignment; the completeness
of any Mortgage Loan; the performance or enforcement of any Mortgage Loan (other
than if the Trustee shall assume the duties of the Servicer pursuant to Section
7.02); the compliance by the Depositor or the Servicer with any warranty or
representation made under this Agreement or in any related document or the
accuracy of any such warranty or representation prior to the Trustee's receipt
of notice or other discovery of any non-compliance therewith or any breach
thereof; any investment of monies by or at the direction of the Servicer or any
loss resulting therefrom, it being understood that the Trustee shall remain
responsible for any Trust property that it may hold in its individual capacity;
the acts or omissions of any of the Servicer (other than if the Trustee shall
assume the duties of the Servicer pursuant to Section 7.02), or any Mortgagor;
any action of the Servicer (other than if the Trustee shall assume the duties of
the Servicer pursuant to Section 7.02), taken in the name of the Trustee; the
failure of the Servicer to act or perform any duties required of it as agent of
the Trustee hereunder; or any action by the Trustee taken at the instruction of
the Servicer (other than if the Trustee shall assume the duties of the Servicer
pursuant to Section 7.02); provided, however, that the foregoing shall not
relieve the Trustee of its obligation to perform its duties under this
Agreement. The Trustee shall not have any responsibility for filing any
financing or continuation statement in any public office at any time or to
otherwise perfect or maintain the perfection of any security interest or lien
granted to it hereunder.

                Section 8.04   Trustee May Own Certificates.

                The Trustee in its individual or any other capacity may become
the owner or pledgee of Certificates with the same rights as it would have if it
were not Trustee and may transact any banking and trust business with the
Servicer, the Depositor or their Affiliates.

                Section 8.05   Trustee Compensation and Expenses.

                The Trustee shall be entitled to investment income from amounts
on deposit in the Distribution Account as compensation for its services
hereunder. The Trust shall reimburse the Trustee for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Agreement (including the reasonable compensation
and the expenses and disbursements of its counsel and of all persons not
regularly in its employ) except any such expense, disbursement or advance as may
arise from its negligence or bad faith or which is the responsibility of
Certificateholders or the Trustee hereunder. In addition, the Trustee and its
officers, directors, employees and agents shall be indemnified by the Trust
from, and held harmless against, any and all losses, liabilities, damages,
claims or expenses incurred in connection with any legal action relating to this
Agreement or the Certificates, other than any loss, liability or expense
incurred by reason of willful misfeasance, bad faith or negligence of the
Trustee in the performance of its duties hereunder or by reason of the Trustee's
reckless disregard of obligations and duties hereunder. This Section shall
survive termination of this Agreement or the resignation or removal of any
Trustee hereunder.

                Section 8.06   Eligibility Requirements for Trustee.

                The Trustee hereunder shall at all times be an entity duly
organized and validly existing under the laws of the United States of America or
any state thereof, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $50,000,000 and a
minimum long-term debt rating of BBB by Fitch and S&P and a long term debt
rating of at least "Baa1" or better by Moody's and subject to supervision or
examination by federal or state authority. If such entity publishes reports of
condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section 8.06, the combined capital and surplus of such entity shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. The principal office of the Trustee (other than the
initial Trustee) shall be in a state with respect to which an Opinion of Counsel
has been delivered to such Trustee at the time such Trustee is appointed Trustee
to the effect that the Trust will not be a taxable entity under the laws of such
state. In case at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 8.06, the Trustee shall resign immediately
in the manner and with the effect specified in Section 8.07.

                Section 8.07   Resignation or Removal of Trustee.

                The Trustee may at any time resign and be discharged from the
trusts hereby created by giving written notice thereof to the Depositor, the
Servicer, the NIMS Insurer and each Rating Agency. Upon receiving such notice of
resignation, the Depositor shall promptly appoint a successor Trustee reasonably
acceptable to the NIMS Insurer by written instrument, in duplicate, one copy of
which instrument shall be delivered to the resigning Trustee and one copy to the
successor Trustee. If no successor Trustee shall have been so appointed and
having accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

                If at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.06 and shall fail to resign after
written request therefor by the Depositor or the NIMS Insurer, or if at any time
the Trustee shall be legally unable to act, or shall be adjudged a bankrupt or
insolvent, or a receiver of the Trustee or of their property shall be appointed,
or any public officer shall take charge or control of the Trustee or of their
property or affairs for the purpose of rehabilitation, conservation or
liquidation, then the Depositor or the NIMS Insurer may remove the Trustee. If
the Depositor or the NIMS Insurer removes the Trustee under the authority of the
immediately preceding sentence, the Depositor or the NIMS Insurer, as the case
may be, shall promptly appoint a successor Trustee (reasonably acceptable to the
NIMS Insurer if appointed by the Depositor) by written instrument, in duplicate,
one copy of which instrument shall be delivered to the Trustee so removed and
one copy to the successor Trustee.

                In addition, if (a) the Trustee fails to comply with its
obligations to deliver any Assessment of Compliance or Attestation Reports
required pursuant to Section 3.20 or (b) any Servicing Function Participant
engaged by the Trustee fails to comply with its obligations to deliver any
Assessment of Compliance or Attestation Reports, the Depositor may remove the
Trustee and appoint a successor trustee by written instrument, in duplicate, one
copy of which instrument shall be delivered to the Trustee so removed and one
copy to the successor trustee.

                The Majority Certificateholders or the NIMS Insurer may at any
time remove the Trustee by written instrument or instruments delivered to the
Servicer, the Depositor, the NIMS Insurer and the Trustee; the Depositor shall
thereupon use its best efforts to appoint a successor Trustee reasonably
acceptable to the NIMS Insurer in accordance with this Section.

                Any resignation or removal of the Trustee and appointment of a
successor Trustee pursuant to any of the provisions of this Section 8.07 shall
not become effective until acceptance of appointment by the successor Trustee as
provided in Section 8.08.

                Section 8.08   Successor Trustee.

                Any successor Trustee appointed as provided in Section 8.07
shall execute, acknowledge and deliver to the Depositor, the NIMS Insurer, the
Rating Agencies, the Servicer and to its predecessor Trustee an instrument
accepting such appointment hereunder, and thereupon the resignation or removal
of the predecessor Trustee shall become effective, and such successor Trustee,
without any further act, deed or conveyance, shall become fully vested with all
the rights, powers, duties and obligations of its predecessor hereunder, with
like effect as if originally named as Trustee. The Depositor, the Servicer and
the predecessor Trustee shall execute and deliver such instruments and do such
other things as may reasonably be required for fully and certainly vesting and
confirming in the successor Trustee all such rights, powers, duties and
obligations.

                No successor Trustee shall accept appointment as provided in
this Section 8.08 unless at the time of such acceptance such successor Trustee
shall be eligible under the provisions of Section 8.06 and the appointment of
such successor Trustee shall not result in a downgrading of the Regular
Certificates by either Rating Agency, as evidenced by a letter from each Rating
Agency.

                Upon acceptance of appointment by a successor Trustee as
provided in this Section 8.08, the successor Trustee shall mail notice of the
appointment of a successor Trustee hereunder to all Holders of Certificates at
their addresses as shown in the Certificate Register and to each Rating Agency.

                The predecessor Trustee and successor Trustee shall notify the
Depositor of any such appointment at least two Business Days prior to the
effective date thereof and shall provide the Depositor with all information
required by the Depositor to comply with its reporting obligation under Item
6.02 of Form 8-K not later than the effective date of such appointment.

                Section 8.09   Merger or Consolidation of Trustee.

                Any entity into which the Trustee may be merged or converted or
with which it may be consolidated, or any entity resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any entity
succeeding to the business of the Trustee, shall be the successor of the
hereunder, provided such entity shall be eligible under the provisions of
Section 8.06 and 8.08, without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding; provided, however, that the Trustee and such surviving
Person shall notify the Depositor of any such merger, conversion or
consolidation and shall provide the Depositor with all information required by
the Depositor to comply with its reporting obligation under Item 6.02 of Form
8-K not later than the effective date of such merger, conversion or
consolidation.

                Section 8.10   Appointment of Co-Trustee or Separate Trustee.

                Notwithstanding any other provisions of this Agreement, at any
time, for the purpose of meeting any legal requirements of any jurisdiction in
which any part of the Trust or any Mortgaged Property may at the time be
located, the Depositor and the Trustee acting jointly shall have the power and
shall execute and deliver all instruments to appoint one or more Persons
approved by the Trustee and the NIMS Insurer to act as co-trustee or
co-trustees, jointly with the Trustee, or separate trustee or separate trustees,
of all or any part of the Trust, and to vest in such Person or Persons, in such
capacity and for the benefit of the Certificateholders, such title to the Trust,
or any part thereof, and, subject to the other provisions of this Section 8.10,
such powers, duties, obligations, rights and trusts as the Servicer and the
Trustee may consider necessary or desirable. Any such co-trustee or separate
trustee shall be subject to the written approval of the Servicer and the NIMS
Insurer. If the Servicer and the NIMS Insurer shall not have joined in such
appointment within 15 days after the receipt by it of a request so to do, or in
the case a Servicer Event of Termination shall have occurred and be continuing,
the Trustee alone shall have the power to make such appointment. No co-trustee
or separate trustee hereunder shall be required to meet the terms of eligibility
as a successor Trustee under Section 8.06, and no notice to Certificateholders
of the appointment of any co-trustee or separate trustee shall be required under
Section 8.08.

                Every separate trustee and co-trustee shall, to the extent
permitted by law, be appointed and act subject to the following provisions and
conditions:

                (i) all rights, powers, duties and obligations conferred or
        imposed upon the Trustee shall be conferred or imposed upon and
        exercised or performed by the Trustee and such separate trustee or
        co-trustee jointly (it being understood that such separate trustee or
        co-trustee is not authorized to act separately without the Trustee
        joining in such act), except to the extent that under any law of any
        jurisdiction in which any particular act or acts are to be performed
        (whether as Trustee hereunder or as successor to the Servicer
        hereunder), the Trustee shall be incompetent or unqualified to perform
        such act or acts, in which event such rights, powers, duties and
        obligations (including the holding of title to the Trust or any portion
        thereof in any such jurisdiction) shall be exercised and performed
        singly by such separate trustee or co-trustee, but solely at the
        direction of the Trustee;

                (ii) no trustee hereunder shall be held personally liable by
        reason of any act or omission of any other trustee hereunder; and

                (iii) the Servicer and the Trustee, acting jointly may at any
        time accept the resignation of or remove any separate trustee or
        co-trustee except that following the occurrence of a Servicer Event of
        Termination, the Trustee acting alone may accept the resignation or
        remove any separate trustee or co-trustee.

                Any notice, request or other writing given to the Trustee shall
be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Agreement and
the conditions of this Article VIII. Each separate trustee and co-trustee, upon
its acceptance of the trusts conferred, shall be vested with the estates or
property specified in its instrument of appointment, either jointly with the
Trustee or separately, as may be provided therein, subject to all the provisions
of this Agreement, specifically including every provision of this Agreement
relating to the conduct of, affecting the liability of, or affording protection
to, the Trustee. Every such instrument shall be filed with the Trustee and a
copy thereof given to the Depositor, the NIMS Insurer, the Rating Agencies and
the Servicer.

                Any separate trustee or co-trustee may, at any time, constitute
the Trustee, its agent or attorney-in-fact, with full power and authority, to
the extent not prohibited by law, to do any lawful act under or in respect of
this Agreement on its behalf and in its name. If any separate trustee or
co-trustee shall die, become incapable of acting, resign or be removed, all of
its estates, properties, rights, remedies and trusts shall vest in and be
exercised by the Trustee, to the extent permitted by law, without the
appointment of a new or successor Trustee.

                Section 8.11   Limitation of Liability.

                The Certificates are executed by the Trustee, not in its
individual capacity but solely as Trustee of the Trust, in the exercise of the
powers and authority conferred and vested in it by this Agreement. Each of the
undertakings and agreements made on the part of the Trustee in the Certificates
is made and intended not as a personal undertaking or agreement by the Trustee
but is made and intended for the purpose of binding only the Trust.

                Section 8.12   Trustee May Enforce Claims Without Possession of
Certificates.

                (a) All rights of action and claims under this Agreement or the
Certificates may be prosecuted and enforced by the Trustee without the
possession of any of the Certificates or the production thereof in any
proceeding relating thereto, and such proceeding instituted by the Trustee shall
be brought in its own name or in its capacity as Trustee for the benefit of all
Holders of such Certificates, subject to the provisions of this Agreement. Any
recovery of judgment shall, after provision for the payment of the reasonable
compensation, expenses, disbursement and advances of the Trustee, its agents and
counsel, be for the ratable benefit of the Certificateholders in respect of
which such judgment has been recovered.

                (b) The Trustee shall afford the Depositor, the Servicer, the
NIMS Insurer and each Certificateholder upon reasonable notice during normal
business hours, access to all records maintained by the Trustee in respect of
its duties hereunder and access to officers of the Trustee responsible for
performing such duties. The Trustee shall cooperate fully with the Servicer, the
NIMS Insurer, the Depositor and such Certificateholder and shall make available
to the Servicer, the NIMS Insurer, the Depositor and such Certificateholder for
review and copying at the expense of the party requesting such copies, such
books, documents or records as may be requested with respect to the Trustee's
duties hereunder. The Depositor, the Servicer, the NIMS Insurer and the
Certificateholders shall not have any responsibility or liability for any action
or failure to act by the Trustee and are not obligated to supervise the
performance of the Trustee under this Agreement or otherwise.

                Section 8.13   Suits for Enforcement.

                In case a Servicer Event of Termination or other default by the
Servicer hereunder shall occur and be continuing, the Trustee may proceed to
protect and enforce its rights and the rights of the Certificateholders under
this Agreement by a suit, action or proceeding in equity or at law or otherwise,
whether for the specific performance of any covenant or agreement contained in
this Agreement or in aid of the execution of any power granted in this Agreement
or for the enforcement of any other legal, equitable or other remedy, as the
Trustee, being advised by counsel, and subject to the foregoing, shall deem most
effectual to protect and enforce any of the rights of the Trustee and the
Certificateholders.

                Section 8.14   Waiver of Bond Requirement.

                The Trustee shall be relieved of, and each Certificateholder
hereby waives, any requirement of any jurisdiction in which the Trust, or any
part thereof, may be located that the Trustee post a bond or other surety with
any court, agency or body whatsoever.

                Section 8.15   Waiver of Inventory, Accounting and Appraisal
Requirement.

                The Trustee shall be relieved of, and each Certificateholder
hereby waives, any requirement of any jurisdiction in which the Trust, or any
part thereof, may be located that the Trustee file any inventory, accounting or
appraisal of the Trust with any court, agency or body at any time or in any
manner whatsoever.

                                   ARTICLE IX

                     REMIC AND GRANTOR TRUST ADMINISTRATION

                Section 9.01   REMIC Administration.

                (a) The Trustee shall (i) make or cause to be made REMIC
elections for each of REMIC 1, REMIC 2, REMIC 3, REMIC 4 and REMIC 5 as set
forth in the Preliminary Statement on Forms 1066 or other appropriate federal
tax or information return for the taxable year ending on the last day of the
calendar year in which the Certificates are issued, and (ii) file Form 8811, or
other applicable form, within 30 days of the Closing Date (or such other period
as may be allowed by applicable law), indicating the name, title, address and
telephone number of the Person who will serve as the representative of REMIC 4
and REMIC 5. The regular interests and residual interest in each REMIC shall be
as designated in the Preliminary Statement.

                (b) The Closing Date is hereby designated as the "Startup Day"
of each REMIC within the meaning of section 860G(a)(9) of the Code.

                (c) The Trustee shall pay any and all tax related expenses (not
including taxes) of each REMIC, including but not limited to any professional
fees or expenses related to audits or any administrative or judicial proceedings
with respect to such REMIC that involve the Internal Revenue Service or state
tax authorities, but only to the extent that (i) such expenses are ordinary or
routine expenses, including expenses of a routine audit but not expenses of
litigation (except as described in (ii)); or (ii) such expenses or liabilities
(including taxes and penalties) are attributable to the negligence or willful
misconduct of the Trustee in fulfilling its duties hereunder. The Trustee shall
be entitled to reimbursement of expenses other than those expenses described in
clause (i) or (ii) above from the Trust.

                (d) The Trustee shall prepare or cause to be prepared, sign and
file or cause to be filed, each REMIC's federal and state tax and information
returns as such REMIC's direct representative. The expenses of preparing and
filing such returns shall be borne by the Trustee.

                (e) The Holder of the Class R Certificate shall be the "tax
matters person" as defined in the REMIC Provisions (the "Tax Matters Person")
with respect to each of REMIC 1, REMIC 2, REMIC 3 and REMIC 4. The Holder of the
Class R-X Certificate shall be the Tax Matters Person with respect to REMIC 5.
The Trustee is irrevocably designated as and shall act as attorney-in-fact and
agent for each such Tax Matters Person. The Trustee, as agent for each such Tax
Matters Person, shall perform, on behalf of each REMIC, all reporting and other
tax compliance duties that are the responsibility of such REMIC under the Code,
the REMIC Provisions, or other compliance guidance issued by the Internal
Revenue Service or any state or local taxing authority. Among its other duties,
if required by the Code, the REMIC Provisions, or other such guidance, the
Trustee, as agent for each such Tax Matters Person, shall provide (i) to the
Treasury or other governmental authority such information as is necessary for
the application of any tax relating to the transfer of a Residual Certificate to
any disqualified person or organization and (ii) to the Certificateholders such
information or reports as are required by the Code or REMIC Provisions.

                (f) The Trustee, the Servicer, and the Holders of Certificates
shall take any action or cause any REMIC formed under this Agreement to take any
action necessary to create or maintain the status of such REMIC as a REMIC under
the REMIC Provisions and shall assist each other as necessary to create or
maintain such status. None of the Trustee, the Servicer or the Holder of a
Residual Certificate shall take any action or cause any REMIC formed under this
Agreement to take any action or fail to take (or fail to cause to be taken) any
action that, under the REMIC Provisions, if taken or not taken, as the case may
be, could (i) endanger the status of such REMIC as a REMIC or (ii) result in the
imposition of a tax upon such REMIC (including but not limited to the tax on
prohibited transactions as defined in Code Section 860F(a)(2) and the tax on
prohibited contributions set forth on Section 860G(d) of the Code) (either such
event, an "Adverse REMIC Event") unless the Trustee, the NIMS Insurer and the
Servicer have received an Opinion of Counsel (at the expense of the party
seeking to take such action) to the effect that the contemplated action will not
endanger such status or result in the imposition of such a tax. In addition,
prior to taking any action with respect to any REMIC formed under this Agreement
or the assets therein, or causing such REMIC to take any action, which is not
expressly permitted under the terms of this Agreement, any Holder of a Residual
Certificate will consult with the Trustee, the NIMS Insurer and the Servicer, or
their respective designees, in writing, with respect to whether such action
could cause an Adverse REMIC Event to occur with respect to such REMIC, and no
such Person shall take any such action or cause such REMIC to take any such
action as to which the Trustee, the NIMS Insurer or the Servicer has advised it
in writing that an Adverse REMIC Event could occur.

                (g) The Holder of a Residual Certificate shall pay when due any
and all taxes imposed on any REMIC formed under this Agreement by federal or
state governmental authorities, but only from amounts, if any, distributable
thereon. To the extent that such REMIC taxes are not paid by a Residual
Certificateholder, the Trustee shall pay any remaining REMIC taxes out of future
amounts otherwise distributable to the Holder of a Residual Certificate or, if
no such amounts are available, out of other amounts held in the Distribution
Account, and shall reduce amounts otherwise payable to Holders of the REMIC
Regular Interests or the Certificates, as the case may be.

                (h) The Trustee, shall, for federal income tax purposes,
maintain or cause to be maintained books and records with respect to each REMIC
formed under this Agreement on a calendar year and on an accrual basis.

                (i) No additional contributions of assets shall be made to any
REMIC, except as expressly provided in this Agreement with respect to Eligible
Substitute Mortgage Loans.

                (j) Neither the Trustee nor the Servicer shall enter into any
arrangement by which any REMIC will receive a fee or other compensation for
services.

                (k) On or before April 15 of each calendar year, beginning in
2006, the Trustee shall deliver to each Rating Agency and the NIMS Insurer an
Officer's Certificate stating the Trustee's compliance with the provisions of
this Section 9.01.

                Section 9.02   Prohibited Transactions and Activities.

                None of the Depositor, the Servicer or the Trustee shall sell,
dispose of, or substitute for any of the Mortgage Loans, except in a disposition
pursuant to (i) the foreclosure of a Mortgage Loan, (ii) the bankruptcy of the
Trust Fund, (iii) the termination of any REMIC pursuant to Article X of this
Agreement, (iv) a substitution pursuant to Article II of this Agreement, or (v)
a repurchase of Mortgage Loans pursuant to Article II of this Agreement, nor
acquire any assets for any REMIC constituting part of the Trust Fund, nor sell
or dispose of any investments in the Distribution Account for gain, nor accept
any contributions to any REMIC constituting part of the Trust Fund after the
Closing Date, unless such party and the NIMS Insurer has received an Opinion of
Counsel (at the expense of the party causing such sale, disposition, or
substitution) that such disposition, acquisition, substitution, or acceptance
will not (a) affect adversely the status of such REMIC as a REMIC or of the
interests therein other than a Residual Certificate as the regular interests
therein, (b) affect the distribution of interest or principal on the
Certificates, (c) result in the encumbrance of the assets transferred or
assigned to the Trust Fund (except pursuant to the provisions of this Agreement)
or (d) cause such REMIC to be subject to a tax on prohibited transactions or
prohibited contributions pursuant to the REMIC Provisions.

                Section 9.03   Indemnification with Respect to Certain Taxes and
Loss of REMIC Status.

                In the event that any REMIC formed hereunder fails to qualify as
a REMIC, loses its status as a REMIC, or incurs federal, state or local taxes as
a result of a prohibited transaction or prohibited contribution under the REMIC
Provisions due to the negligent performance by the Servicer of its duties and
obligations set forth herein, the Servicer shall indemnify the Holder of a
Residual Certificate against any and all losses, claims, damages, liabilities or
expenses ("Losses") resulting from such negligence; provided, however, that the
Servicer shall not be liable for any such Losses attributable to the action or
inaction of the Trustee, the Depositor or the Holder of a Residual Certificate,
as applicable, nor for any such Losses resulting from misinformation provided by
the Holder of a Residual Certificate on which the Servicer has relied. The
foregoing shall not be deemed to limit or restrict the rights and remedies of
the Holder of a Residual Certificate now or hereafter existing at law or in
equity. Notwithstanding the foregoing, however, in no event shall the Servicer
have any liability (1) for any action or omission that is taken in accordance
with and in compliance with the express terms of, or which is expressly
permitted by the terms of, this Agreement, (2) for any Losses other than arising
out of a negligent performance by the Servicer of its duties and obligations set
forth herein, and (3) for any special or consequential damages to
Certificateholders (in addition to payment of principal and interest on the
Certificates).

                Section 9.04   REO Property.

                (a) Subject to compliance with applicable laws and regulations
as shall at any time be in force, and notwithstanding any other provision of
this Agreement, the Servicer, acting on behalf of the Trust hereunder, shall not
rent, lease, or otherwise earn income on behalf of any REMIC with respect to any
REO Property which might cause such REO Property to fail to qualify as
"foreclosure" property within the meaning of section 860G(a)(8) of the Code or
result in the receipt by any REMIC of any "income from non-permitted assets"
within the meaning of section 860F(a)(2) of the Code or any "net income from
foreclosure property" which is subject to tax under the REMIC Provisions unless
the Servicer has advised, or has caused the applicable Servicer to advise, the
Trustee in writing to the effect that, under the REMIC Provisions, such action
would not adversely affect the status of any REMIC as a REMIC and any income
generated for such REMIC by the REO Property would not result in the imposition
of a tax upon such REMIC.

                (b) The Servicer shall make reasonable efforts to sell any REO
Property for its fair market value. In any event, however, the Servicer shall
dispose of any REO Property before the close of the third calendar year
beginning after the year of its acquisition by the Trust Fund unless the
Servicer has received a grant of extension from the Internal Revenue Service to
the effect that, under the REMIC Provisions and any relevant proposed
legislation and under applicable state law, any REMIC constituting part of the
Trust Fund may hold REO Property for a longer period without adversely affecting
its REMIC status or causing the imposition of a Federal or state tax upon any
REMIC constituting part of the Trust Fund. If the Servicer has received such an
extension, then the Servicer shall continue to attempt to sell the REO Property
for its fair market value as determined in good faith by the Servicer for such
longer period as such extension permits (the "Extended Period"). If the Servicer
has not received such an extension and the Servicer is unable to sell the REO
Property within 33 months after its acquisition by the Trust Fund or if the
Servicer has received such an extension, and the Servicer is unable to sell the
REO Property within the period ending three months before the close of the
Extended Period, the Servicer shall, before the end of the applicable period,
(i) purchase such REO Property at a price equal to the REO Property's fair
market value as determined in good faith by the Servicer or (ii) auction the REO
Property to the highest bidder (which may be the Servicer) in an auction
reasonably designed to produce a fair price prior to the expiration of the
applicable period.

                Section 9.05   Grantor Trust Administration.

                The parties intend that the portions of the Trust Fund
consisting of (i) the right of the Class P Certificates to receive Prepayment
Charges, Originator Prepayment Charge Payment Amounts and Servicer Prepayment
Charge Payment Amounts, (ii) the right of the Offered Certificates and the Class
B Certificates to receive Cap Carryover Amounts and (iii) the Interest Rate Swap
Agreement, the Swap Account and the beneficial interest of the Class CE
Certificates with respect thereto subject to the obligation of the Class CE
Certificates to pay Cap Carryover Amounts shall be treated as a "grantor trust"
under the Code, and the provisions hereof shall be interpreted consistently with
this intention. In furtherance of such intention, the Trustee shall furnish or
cause to be furnished (x) to the Holders of the Offered Certificates and the
Class B Certificates, (y) to the Holders of the Class P Certificates and (z) to
the Holder of the Class CE Certificates and shall file or cause to be filed with
the Internal Revenue Service together with Form 1041 or such other form as may
be applicable, their allocable shares of income and expenses with respect to the
property held by the Grantor Trust, at the time or times and in the manner
required by the Code.

                                   ARTICLE X

                                   TERMINATION

                Section 10.01   Termination.

                (a) The respective obligations and responsibilities of the
Servicer, the Depositor, the Trustee and the Certificate Registrar created
hereby (other than the obligation of the Trustee to make certain payments to
Certificateholders after the final Distribution Date and the obligation of the
Servicer to send certain notices as hereinafter set forth) shall terminate upon
notice to the Trustee upon the earliest of (i) the Distribution Date on which
the Certificate Principal Balance of each Class of Certificates has been reduced
to zero, (ii) the final payment or other liquidation of the last Mortgage Loan
in the Trust, and (iii) the optional purchase by the NIMS Insurer, if there is a
NIMS Insurer, or if there is no NIMS Insurer, the Majority Class CE
Certificateholders (or if such holder is the Seller, or an affiliate of the
Seller, the Servicer of the Mortgage Loans) as described below. Notwithstanding
the foregoing, in no event shall the trust created hereby continue beyond the
expiration of 21 years from the death of the last survivor of the descendants of
Joseph P. Kennedy, the late ambassador of the United States to the Court of St.
James, living on the date hereof.

                The NIMS Insurer, if there is a NIMS Insurer, or if there is no
NIMS Insurer, the Majority Class CE Certificateholders (and, if such holder is
the Seller or an affiliate of the Seller, the Servicer of the Mortgage Loans)
may, at its option, terminate the Trust Fund and retire the Certificates on the
Distribution Date following the Distribution Date upon which the aggregate
current Pool Balance is less than 10% of the sum of the aggregate Pool Balance
of the Initial Mortgage Loans as of the Cut-off Date and the Original Group 3
Pre-Funded Amount by purchasing all of the outstanding Mortgage Loans and REO
Properties in the Trust Fund at a price equal to (i) the sum of the outstanding
Principal Balance of the Mortgage Loans and except to the extent previously
advanced by the Servicer, accrued and unpaid interest thereon at the weighted
average of the Mortgage Interest Rates through the end of the Collection Period
preceding the final Distribution Date plus unreimbursed Servicing Advances,
Advances and any unpaid Servicing Fees allocable to such Mortgage Loans, (ii)
the fair market value of the REO Properties as determined in good faith by the
Servicer and (iii) any Swap Termination Payment owed to the Swap Provider not
due to a Swap Provider Trigger Event pursuant to the Interest Rate Swap
Agreement (the "Termination Price"). If the NIMS Insurer or the Majority Class
CE Certificateholders (or, if the Majority Class CE Certificateholder is the
Seller or an affiliate of the Seller, the Servicer) is subject to regulation by
the OCC, the FDIC, the Federal Reserve or the Office of Thrift Supervision,
however, the option may not be exercised unless the aggregate fair market value
of the Mortgage Loans and REO Properties is greater than or equal to the
Termination Price. Notwithstanding the foregoing, no party may exercise this
optional purchase right unless any Reimbursement Amount owed to the Trust
pursuant to Section 2.03 hereof has been paid.

                In connection with any such purchase pursuant to the preceding
paragraph, the Servicer shall deliver to the Trustee for deposit in the
Distribution Account all amounts then on deposit in the Collection Account (less
amounts permitted to be withdrawn by the Servicer pursuant to Section 3.07),
which deposit shall be deemed to have occurred immediately following such
purchase.

                Any such purchase shall be accomplished by delivery on the
Determination Date before such Distribution Date of the Termination Price to the
Trustee for deposit into the Distribution Account as part of Available Funds.

                (b) Notice of any termination, specifying the Distribution Date
(which shall be a date that would otherwise be a Distribution Date) upon which
the Certificateholders may surrender their Certificates to the Trustee for
payment of the final distribution and cancellation, shall be given promptly by
the Trustee upon the Trustee receiving notice of such date from the NIMS
Insurer, the Majority Class CE Certificateholders or the Servicer, as
applicable, by letter to the Certificateholders mailed not earlier than the 15th
day of the month preceding the month of such final distribution and not later
than the 15th day of the month of such final distribution specifying (1) the
Distribution Date upon which final distribution of the Certificates will be made
upon presentation and surrender of such Certificates at the office or agency of
the Trustee therein designated, (2) the amount of any such final distribution
and (3) that the Record Date otherwise applicable to such Distribution Date is
not applicable, distributions being made only upon presentation and surrender of
the Certificates at the office or agency of the Trustee therein specified. Not
less than five (5) Business Days prior to such Determination Date relating to
such Distribution Date, the Trustee shall notify the Originators and the Seller
of the amount of any unpaid Reimbursement Amount owed to the Trust.

                (c) Upon presentation and surrender of the Certificates, the
Trustee shall cause to be distributed to the Holders of the Certificates on the
Distribution Date for such final distribution, in proportion to the Percentage
Interests of their respective Class and to the extent that funds are available
for such purpose, an amount equal to the amount required to be distributed to
such Holders in accordance with the provisions of Sections 4.01 and 4.02 for
such Distribution Date.

                (d) In the event that all Certificateholders shall not surrender
their Certificates for final payment and cancellation on or before such final
Distribution Date, the Trustee shall promptly following such date cause all
funds in the Distribution Account not distributed in final distribution to
Certificateholders to be withdrawn therefrom and credited to the remaining
Certificateholders by depositing such funds in a separate escrow account for the
benefit of such Certificateholders, and the Servicer shall give a second written
notice to the remaining Certificateholders, to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
nine months after the second notice all the Certificates shall not have been
surrendered for cancellation, a Residual Certificateholder shall be entitled to
all unclaimed funds and other assets which remain subject hereto (except with
respect to the Class CE and Class P Certificates) and the Trustee upon transfer
of such funds shall be discharged of any responsibility for such funds, and all
other Certificateholders shall look to a Residual Certificateholder for payment.

                Section 10.02   Additional Termination Requirements.

                (a) In the event that the NIMS Insurer, the Majority Class CE
Certificateholders or the Servicer, as applicable, exercise its purchase option
as provided in Section 10.01, the Trust shall be terminated in accordance with
the following additional requirements, unless the Trustee shall have been
furnished with an Opinion of Counsel to the effect that the failure of the Trust
to comply with the requirements of this Section will not (i) result in the
imposition of taxes on "prohibited transactions" of the Trust as defined in
Section 860F of the Code or (ii) cause any REMIC constituting part of the Trust
Fund to fail to qualify as a REMIC at any time that any Certificates (other than
the Class P Certificates) are outstanding:

                (i) The Trustee shall designate a date within 90 days prior to
        the final Distribution Date as the date of adoption of plans of complete
        liquidation of each of REMIC 1, REMIC 2, REMIC 3, REMIC 4 and REMIC 5
        and shall specify such date in the final federal income tax return of
        each REMIC;

                (ii) After the date of adoption of such plans of complete
        liquidation and at or prior to the final Distribution Date, the Trustee
        shall sell all of the assets of the Trust to the Majority Class CE
        Certificateholders or the Servicer, as applicable, for cash; and

                (iii) At the time of the making of the final payment on the
        Certificates, the Trustee shall distribute or credit, or cause to be
        distributed or credited in the order of priority set forth in Section
        4.02 and then to the Holders of the Class R Certificates, all cash on
        hand in respect of the REMIC 1, REMIC 2, REMIC 3 and REMIC 4, or to the
        Holders of the Class R-X Certificates, all cash on hand in respect of
        the REMIC 5, after such payment (other than cash retained to meet
        claims) and the Trust shall terminate at such time.

                (b) By their acceptance of Certificates, the Holders thereof
hereby agree to appoint the Trustee as their attorney in fact to: (i) designate
such date of adoption of plans of complete liquidation and (ii) to take such
other action in connection therewith as may be reasonably required to carry out
such plans of complete liquidation all in accordance with the terms hereof.

                                   ARTICLE XI

                            MISCELLANEOUS PROVISIONS

                Section 11.01   Amendment.

                This Agreement may be amended from time to time by the
Depositor, the Servicer and the Trustee; with the consent of the NIMS Insurer
and without the consent of the Certificateholders, (i) to cure any ambiguity or
mistake, (ii) to correct, modify or supplement any provision herein which may be
inconsistent with any other provision herein or the Prospectus Supplement, (iii)
to make any other provisions with respect to matters or questions arising under
this Agreement, which shall not be inconsistent with the provisions of this
Agreement, (iv) to comply with any requirements imposed by the Code, (v) to
conform the obligations of the parties under this Agreement, or to add
obligations of the parties to this Agreement, if necessary, to comply with the
requirements of Regulation AB or (vi) to provide for the rights of the NIMS
Insurer; provided, however, that any such action listed in clause (iii) above
shall not adversely affect in any respect the interests of any
Certificateholder, as evidenced by (i) notice in writing to the Depositor, the
Servicer and the Trustee from the Rating Agencies that such action will not
result in the reduction or withdrawal of the rating of any outstanding Class of
Certificates with respect to which it is a Rating Agency, or (ii) an Opinion of
Counsel delivered to the Servicer and the Trustee.

                In addition, this Agreement may be amended from time to time by
the Depositor, the Servicer and the Trustee, with the consent of the NIMS
Insurer and the Majority Certificateholders for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Agreement or of modifying in any manner the rights of the Swap Provider or
the Holders of Certificates; provided, however, that no such amendment or waiver
shall (x) reduce in any manner the amount of, or delay the timing of, payments
on the Certificates which are required to be made on any Certificate without the
consent of the Holder of such Certificate, (y) adversely affect in any material
respect the interests of the Holders of any Class of Certificates or the Swap
Provider in a manner other than as described in clause (x) above, without the
consent of the Holders of Certificates of such Class evidencing at least 66 2/3%
of the Voting Rights evidenced by such Class, or (z) reduce the percentage of
Voting Rights required by clause (y) above without the consent of the Holders of
all Certificates of such Class then outstanding. Upon approval of an amendment,
a copy of such amendment shall be sent to the Rating Agencies. Prior to the
execution of any amendment to this Agreement, the Trustee shall be entitled to
receive and rely upon an Opinion of Counsel (at the expense of the Person
seeking such amendment) stating that the execution of such amendment is
authorized or permitted by this Agreement. The Trustee may, but shall not be
obligated to, enter into any such amendment which affects the Trustee's own
rights, duties or immunities under this Agreement.

                Notwithstanding any provision of this Agreement to the contrary,
neither the Trustee nor the NIMS Insurer shall consent to any amendment to this
Agreement unless it shall have first received an Opinion of Counsel, delivered
by (and at the expense of) the Person seeking such Amendment, to the effect that
such amendment will not result in the imposition of a tax on any REMIC
constituting part of the Trust Fund pursuant to the REMIC Provisions or cause
any REMIC constituting part of the Trust Fund to fail to qualify as a REMIC at
any time that any Certificates (other than the Class P Certificates) are
outstanding and that the amendment is being made in accordance with the terms
hereof.

               Notwithstanding any of the other provisions of this Section
11.01, none of the Depositor, the Servicer or the Trustee shall enter into any
amendment to Sections 4.01, 4.02 or 4.09 of this Agreement without the prior
written consent of the Swap Provider.

               Promptly after the execution of any such amendment the Trustee
shall furnish, at the expense of the Person that requested the amendment if such
Person is the Servicer (but in no event at the expense of the Trustee),
otherwise at the expense of the Trust, a copy of such amendment and the Opinion
of Counsel referred to in the immediately preceding paragraph to the Servicer
and each Rating Agency.

                It shall not be necessary for the consent of Certificateholders
under this Section 11.01 to approve the particular form of any proposed
amendment; instead it shall be sufficient if such consent shall approve the
substance thereof. The manner of obtaining such consents and of evidencing the
authorization of the execution thereof by Certificateholders shall be subject to
such reasonable regulations as the Trustee may prescribe.

                Section 11.02   Recordation of Agreement; Counterparts.

                To the extent permitted by applicable law, this Agreement is
subject to recordation in all appropriate public offices for real property
records in all the counties or other comparable jurisdictions in which any or
all of the properties subject to the Mortgages are situated, and in any other
appropriate public recording office or elsewhere, such recordation to be
effected by the Servicer at the expense of the Trust, but only upon direction of
Certificateholders, accompanied by an Opinion of Counsel to the effect that such
recordation materially and beneficially affects the interests of the
Certificateholders.

                For the purpose of facilitating the recordation of this
Agreement as herein provided and for other purposes, this Agreement may be
executed simultaneously in any number of counterparts, each of which
counterparts shall be deemed to be an original, and such counterparts shall
together constitute but one and the same instrument.

                Section 11.03   Limitation on Rights of Certificateholders.

                The death or incapacity of any Certificateholder shall not (i)
operate to terminate this Agreement or the Trust, (ii) entitle such
Certificateholder's legal representatives or heirs to claim an accounting or to
take any action or proceeding in any court for a partition or winding up of the
Trust, or (iii) otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

                Except as expressly provided for herein, no Certificateholder
shall have any right to vote or in any manner otherwise control the operation
and management of the Trust, or the obligations of the parties hereto, nor shall
anything herein set forth or contained in the terms of the Certificates be
construed so as to constitute the Certificateholders from time to time as
partners or members of an association; nor shall any Certificateholder be under
any liability to any third person by reason of any action taken by the parties
to this Agreement pursuant to any provision hereof.

                No Certificateholder shall have any right by virtue of any
provision of this Agreement to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Agreement, unless such
Holder previously shall have given to the Trustee a written notice of default
and of the continuance thereof, as herein provided, and unless also the Holders
of Certificates having not less than 51% of the Voting Rights shall have made
written request upon the Trustee to institute such action, suit or proceeding in
its own name as Trustee hereunder and shall have offered to the Trustee such
reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee for 60 days after
its receipt of such notice, request and offer of indemnity, shall have neglected
or refused to institute any such action, suit or proceeding. It is understood
and intended, and expressly covenanted by each Certificateholder with every
other Certificateholder and the Trustee, that no one or more Holders of
Certificates shall have any right in any manner whatever by virtue of any
provision of this Agreement to affect, disturb or prejudice the rights of the
Holders of any other of such Certificates, or to obtain or seek to obtain
priority over or preference to any other such Holder, which priority or
preference is not otherwise provided for herein, or to enforce any right under
this Agreement, except in the manner herein provided and for the equal, ratable
and common benefit of all Certificateholders. For the protection and enforcement
of the provisions of this Section 11.03 each and every Certificateholder and the
Trustee shall be entitled to such relief as can be given either at law or in
equity.

                Section 11.04   Governing Law; Jurisdiction.

                Section 11.10   Third Party Beneficiary.

                Nothing in this Agreement or in the Certificates, expressed or
implied, shall give to any Person, other than the Certificateholders, the
parties hereto and the NIMS Insurer and their successors hereunder, any benefit
or any legal or equitable right, remedy or claim under this Agreement.

the right to enforce the provisions of this Agreement directly against the
parties to this Agreement.

instruments of substantially similar tenor signed by such Certificateholders in
person or by agent duly appointed in writing; and such action shall become
effective when such instrument or instruments are delivered to the Trustee and
the Servicer. Such instrument or instruments (and the action embodied therein
and evidenced thereby) are herein sometimes referred to as the "act" of the

consent, waiver or other action by any Certificateholder shall bind every future

Reasonableness.

                The parties hereto acknowledge that interpretations of the

in the asset-backed securities markets, advice of counsel, or otherwise, and

faith for delivery of information under these provisions on the basis of

            This certifies that _______________ is the registered owner of a
Percentage Interest (obtained by dividing the Initial Certificate Principal
Balance of this Certificate by the Original Class Certificate Principal Balance
of the Class A-1 Certificates) in that certain beneficial ownership interest

to a Pooling and Servicing Agreement, dated as specified above (the
"Agreement"), among Asset Backed Funding Corporation (hereinafter called the
"Depositor," which term includes any successor entity under the Agreement), the
Servicer and the Trustee, a summary of certain of the pertinent provisions of
which is set forth hereafter. To the extent not defined herein, the capitalized
terms used herein have the meanings assigned in the Agreement. This Certificate
is issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Certificate by virtue of the
acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (a "Distribution Date"), commencing on the
first Distribution Date specified above, to the Person in whose name this
Certificate is registered on the Business Day immediately preceding such
Distribution Date (the "Record Date"), from funds in the Distribution Account in
an amount equal to the product of the Percentage Interest evidenced by this
Certificate and the amount required to be distributed to the Holders of Class
A-1 Certificates on such Distribution Date pursuant to the Agreement; provided,
however, that if any Class A-1 Certificate becomes a Definitive Certificate, the
Record Date for such Certificate will be the last Business Day of the month
immediately preceding the month in which the related Distribution Date occurs.

            All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by or on behalf of the Trustee by
wire transfer in immediately available funds to the account of the Person
entitled thereto if such Person shall have so notified the Certificate Registrar
in writing at least five Business Days prior to the Record Date immediately
prior to such Distribution Date and is the registered owner of Class A-1
Certificates, or by check mailed by first class mail to the address of the
Person entitled thereto, as such name and address shall appear on the
Certificate Register, provided that the Certificate Registrar may deduct a
reasonable wire transfer fee from any payment made by wire transfer.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose as provided in the Agreement.

            The Certificate Interest Rate for the Class A-1 Certificates for
each Distribution Date will be the least of (i) One-Month LIBOR as of the
related LIBOR Determination Date plus the Class A-1 Certificate Margin, (ii) the
Group 1 Maximum Rate Cap and (iii) the Group 1 Cap. Interest will accrue on the
Class A-1 Certificates during each Interest Accrual Period at the Certificate
Interest Rate.

            This Certificate is one of a duly authorized issue of Certificates
designated as ABFC Asset-Backed Certificates of the Series specified on the face
hereof (herein called the "Certificates") and representing a Percentage Interest
in the Class A-1 Certificates.

            The Class A-1 Certificates are limited in right of payment to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer and the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to the Voting Rights
identified in the agreement. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee and
the Certificate Registrar duly executed by, the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations evidencing the same aggregate
Percentage Interest will be issued to the designated transferee or transferees.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and none of the Depositor, the
Servicer, the Trustee, the Certificate Registrar nor any such agent shall be
affected by notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement, subject to certain conditions set forth in Article X of the
Agreement, to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at the Termination Price on the
Optional Termination Date. The exercise of such right will effect early
retirement of the Certificates.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

to a Pooling and Servicing Agreement, dated as specified above (the

"Depositor," which term includes any successor entity under the Agreement), the
Servicer and the Trustee, a summary of certain of the pertinent provisions of
which is set forth hereafter. To the extent not defined herein, the capitalized
terms used herein have the meanings assigned in the Agreement. This Certificate
is issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Certificate by virtue of the
acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made

Business Day immediately following (a "Distribution Date"), commencing on the

Distribution Date (the "Record Date"), from funds in the Distribution Account in

A-2 Certificates on such Distribution Date pursuant to the Agreement; provided,
however, that if any Class A-2 Certificate becomes a Definitive Certificate, the
Record Date for such Certificate will be the last Business Day of the month
immediately preceding the month in which the related Distribution Date occurs.

            All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by or on behalf of the Trustee by
wire transfer in immediately available funds to the account of the Person
entitled thereto if such Person shall have so notified the Certificate Registrar
in writing at least five Business Days prior to the Record Date immediately
prior to such Distribution Date and is the registered owner of Class A-2
Certificates, or by check mailed by first class mail to the address of the
Person entitled thereto, as such name and address shall appear on the

Notwithstanding the above, the final distribution on this Certificate will be

related LIBOR Determination Date plus the Class A-2 Certificate Margin, (ii) the
Group 2 Maximum Rate Cap and (iii) the Group 2 Cap. Interest will accrue on the

            This Certificate is one of a duly authorized issue of Certificates
designated as ABFC Asset-Backed Certificates of the Series specified on the face
hereof (herein called the "Certificates") and representing a Percentage Interest
in the Class A-2 Certificates.

            The Class A-2 Certificates are limited in right of payment to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer and the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to the Voting Rights
identified in the agreement. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee and
the Certificate Registrar duly executed by, the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations evidencing the same aggregate
Percentage Interest will be issued to the designated transferee or transferees.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and none of the Depositor, the
Servicer, the Trustee, the Certificate Registrar nor any such agent shall be
affected by notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement, subject to certain conditions set forth in Article X of the
Agreement, to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at the Termination Price on the
Optional Termination Date. The exercise of such right will effect early
retirement of the Certificates.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee and
the Certificate Registrar duly executed by, the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations evidencing the same aggregate
Percentage Interest will be issued to the designated transferee or transferees.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and none of the Depositor, the
Servicer, the Trustee, the Certificate Registrar nor any such agent shall be
affected by notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement, subject to certain conditions set forth in Article X of the
Agreement, to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at the Termination Price on the
Optional Termination Date. The exercise of such right will effect early
retirement of the Certificates.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            This certifies that _______________ is the registered owner of a
Percentage Interest (obtained by dividing the Initial Certificate Principal
Balance of this Certificate by the Original Class Certificate Principal Balance
of the Class A-3D Certificates) in that certain beneficial ownership interest

to a Pooling and Servicing Agreement, dated as specified above (the
"Agreement"), among Asset Backed Funding Corporation (hereinafter called the
"Depositor," which term includes any successor entity under the Agreement), the
Servicer and the Trustee, a summary of certain of the pertinent provisions of
which is set forth hereafter. To the extent not defined herein, the capitalized
terms used herein have the meanings assigned in the Agreement. This Certificate
is issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Certificate by virtue of the
acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (a "Distribution Date"), commencing on the
first Distribution Date specified above, to the Person in whose name this
Certificate is registered on the Business Day immediately preceding such
Distribution Date (the "Record Date"), from funds in the Distribution Account in
an amount equal to the product of the Percentage Interest evidenced by this
Certificate and the amount required to be distributed to the Holders of Class
A-3D Certificates on such Distribution Date pursuant to the Agreement; provided,
however, that if any Class A-3D Certificate becomes a Definitive Certificate,
the Record Date for such Certificate will be the last Business Day of the month
immediately preceding the month in which the related Distribution Date occurs.

            All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by or on behalf of the Trustee by

entitled thereto if such Person shall have so notified the Certificate Registrar

prior to such Distribution Date and is the registered owner of Class A-3D
Certificates, or by check mailed by first class mail to the address of the
Person entitled thereto, as such name and address shall appear on the

Notwithstanding the above, the final distribution on this Certificate will be

each Distribution Date will be the least of (i) One-Month LIBOR as of the
related LIBOR Determination Date plus the Class A-3D Certificate Margin, (ii)
the Group 3 Maximum Rate Cap and (iii) the Group 3 Cap. Interest will accrue on
the Class A-3D Certificates during each Interest Accrual Period at the
Certificate Interest Rate.

            This Certificate is one of a duly authorized issue of Certificates
designated as ABFC Asset-Backed Certificates of the Series specified on the face
hereof (herein called the "Certificates") and representing a Percentage Interest

certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer and the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to the Voting Rights
identified in the agreement. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee and
the Certificate Registrar duly executed by, the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations evidencing the same aggregate
Percentage Interest will be issued to the designated transferee or transferees.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and none of the Depositor, the
Servicer, the Trustee, the Certificate Registrar nor any such agent shall be
affected by notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement, subject to certain conditions set forth in Article X of the
Agreement, to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at the Termination Price on the
Optional Termination Date. The exercise of such right will effect early
retirement of the Certificates.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

which is set forth hereafter. To the extent not defined herein, the capitalized
terms used herein have the meanings assigned in the Agreement. This Certificate

M-2 Certificates on such Distribution Date pursuant to the Agreement; provided,
however, that if any Class M-2 Certificate becomes a Definitive Certificate, the

certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account

Servicing Agreement referred to herein.

            The Agreement permits, with certain exceptions therein provided, the

Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to the Voting Rights
identified in the agreement. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee and
the Certificate Registrar duly executed by, the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations evidencing the same aggregate
Percentage Interest will be issued to the designated transferee or transferees.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and none of the Depositor, the
Servicer, the Trustee, the Certificate Registrar nor any such agent shall be
affected by notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement, subject to certain conditions set forth in Article X of the
Agreement, to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at the Termination Price on the
Optional Termination Date. The exercise of such right will effect early
retirement of the Certificates.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and none of the Depositor, the
Servicer, the Trustee, the Certificate Registrar nor any such agent shall be
affected by notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement, subject to certain conditions set forth in Article X of the
Agreement, to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at the Termination Price on the
Optional Termination Date. The exercise of such right will effect early
retirement of the Certificates.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

      BACKED FUNDING CORPORATION, THE SERVICER, THE TRUSTEE OR ANY OF THEIR
      AFFILIATES. THIS CERTIFICATE IS NOT GUARANTEED BY ANY AGENCY OR
      INSTRUMENTALITY OF THE UNITED STATES.

            This certifies that _________________ is the registered owner of a
Percentage Interest (obtained by dividing the Initial Certificate Principal
Balance of this Certificate by the Original Class Certificate Principal Balance
of the Class M-4 Certificates) in that certain beneficial ownership interest
evidenced by all the Class M-4 Certificates in the Trust Fund created pursuant
to a Pooling and Servicing Agreement, dated as specified above (the
"Agreement"), among Asset Backed Funding Corporation (hereinafter called the
"Depositor," which term includes any successor entity under the Agreement), the
Servicer and the Trustee, a summary of certain of the pertinent provisions of
which is set forth hereafter. To the extent not defined herein, the capitalized
terms used herein have the meanings assigned in the Agreement. This Certificate
is issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Certificate by virtue of the
acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (a "Distribution Date"), commencing on the
first Distribution Date specified above, to the Person in whose name this
Certificate is registered on the Business Day immediately preceding such
Distribution Date (the "Record Date"), from funds in the Distribution Account in
an amount equal to the product of the Percentage Interest evidenced by this
Certificate and the amount required to be distributed to the Holders of Class
M-4 Certificates on such Distribution Date pursuant to the Agreement; provided,
however, that if any Class M-4 Certificate becomes a Definitive Certificate, the
Record Date for such Certificate will be the last Business Day of the month
immediately preceding the month in which the related Distribution Date occurs.

            All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by or on behalf of the Trustee by
wire transfer in immediately available funds to the account of the Person
entitled thereto if such Person shall have so notified the Certificate Registrar

designated as ABFC Asset-Backed Certificates of the Series specified on the face
hereof (herein called the "Certificates") and representing a Percentage Interest

certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account

Certificates as described in the Pooling and Servicing Agreement referred to
herein.

            The Agreement permits, with certain exceptions therein provided, the

Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to the Voting Rights
identified in the agreement. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee and
the Certificate Registrar duly executed by, the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations evidencing the same aggregate
Percentage Interest will be issued to the designated transferee or transferees.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and none of the Depositor, the
Servicer, the Trustee, the Certificate Registrar nor any such agent shall be
affected by notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement, subject to certain conditions set forth in Article X of the
Agreement, to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at the Termination Price on the
Optional Termination Date. The exercise of such right will effect early
retirement of the Certificates.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            Pursuant to the terms of the Agreement, distributions will be made
on the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (a "Distribution Date"), commencing on the
first Distribution Date specified above, to the Person in whose name this
Certificate is registered on the Business Day immediately preceding such
Distribution Date (the "Record Date"), from funds in the Distribution Account in
an amount equal to the product of the Percentage Interest evidenced by this
Certificate and the amount required to be distributed to the Holders of Class
M-5 Certificates on such Distribution Date pursuant to the Agreement; provided,
however, that if any Class M-5 Certificate becomes a Definitive Certificate, the
Record Date for such Certificate will be the last Business Day of the month
immediately preceding the month in which the related Distribution Date occurs.

            All distributions to the Holder of this Certificate under the
Agreement will be made or caused to be made by or on behalf of the Trustee by
wire transfer in immediately available funds to the account of the Person
entitled thereto if such Person shall have so notified the Certificate Registrar
in writing at least five Business Days prior to the Record Date immediately
prior to such Distribution Date and is the registered owner of Class M-5
Certificates, or by check mailed by first class mail to the address of the
Person entitled thereto, as such name and address shall appear on the
Certificate Register, provided that the Certificate Registrar may deduct a
reasonable wire transfer fee from any payment made by wire transfer.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose as provided in the Agreement.

            The Certificate Interest Rate for the Class M-5 Certificates for
each Distribution Date will be the least of (i) One-Month LIBOR as of the
related LIBOR Determination Date plus the Class M-5 Certificate Margin, (ii) the
Pool Maximum Rate Cap and (iii) the Pool Cap. Interest will accrue on the Class
M-5 Certificates during each Interest Accrual Period at the Certificate Interest
Rate.

            This Certificate is one of a duly authorized issue of Certificates
designated as ABFC Asset-Backed Certificates of the Series specified on the face
hereof (herein called the "Certificates") and representing a Percentage Interest
in the Class M-5 Certificates.

            The Class M-5 Certificates are limited in right of payment to
certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            This certificate is subordinated in right of payment to the Class A
Certificates, Class M-1 Certificates, Class M-2 Certificates, Class M-3
Certificates and Class M-4 Certificates as described in the Pooling and
Servicing Agreement referred to herein.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to the Voting Rights
identified in the agreement. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee and
the Certificate Registrar duly executed by, the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations evidencing the same aggregate
Percentage Interest will be issued to the designated transferee or transferees.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and none of the Depositor, the
Servicer, the Trustee, the Certificate Registrar nor any such agent shall be
affected by notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement, subject to certain conditions set forth in Article X of the
Agreement, to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at the Termination Price on the
Optional Termination Date. The exercise of such right will effect early
retirement of the Certificates.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

Business Day immediately following (a "Distribution Date"), commencing on the

identified in the agreement. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of

made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

Agreement, duly endorsed by, or accompanied by an assignment in the form below

limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same

or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and none of the Depositor, the
Servicer, the Trustee, the Certificate Registrar nor any such agent shall be
affected by notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement, subject to certain conditions set forth in Article X of the
Agreement, to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at the Termination Price on the
Optional Termination Date. The exercise of such right will effect early
retirement of the Certificates.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

on the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (a "Distribution Date"), commencing on the
first Distribution Date specified above, to the Person in whose name this
Certificate is registered on the Business Day immediately preceding such

designated as ABFC Asset-Backed Certificates of the Series specified on the face
hereof (herein called the "Certificates") and representing a Percentage Interest

certain collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or

amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to the Voting Rights
identified in the agreement. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of

Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee and
the Certificate Registrar duly executed by, the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations evidencing the same aggregate
Percentage Interest will be issued to the designated transferee or transferees.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and none of the Depositor, the
Servicer, the Trustee, the Certificate Registrar nor any such agent shall be
affected by notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement, subject to certain conditions set forth in Article X of the
Agreement, to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at the Termination Price on the
Optional Termination Date. The exercise of such right will effect early
retirement of the Certificates.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

among Asset Backed Funding Corporation (hereinafter called the "Depositor,"
which term includes any successor entity under the Agreement), the Servicer and
the Trustee, a summary of certain of the pertinent provisions of which is set
forth hereafter. To the extent not defined herein, the capitalized terms used
herein have the meanings assigned in the Agreement. This Certificate is issued
under and is subject to the terms, provisions and conditions of the Agreement,

hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made

Business Day immediately following (a "Distribution Date"), commencing on the
first Distribution Date specified above, to the Person in whose name this

however, that if any Class B Certificate becomes a Definitive Certificate, the

            This Certificate is one of a duly authorized issue of Certificates
designated as ABFC Asset-Backed Certificates of the Series specified on the face
hereof (herein called the "Certificates") and representing a Percentage Interest
in the Class B Certificates.

            The Class B Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            This certificate is subordinated in right of payment to the Class A
Certificates, Class M-1 Certificates, Class M-2 Certificates, Class M-3
Certificates, Class M-4 Certificates, Class M-5 Certificates, Class M-6
Certificates, Class M-7 Certificates, Class M-8 Certificates and Class M-9
Certificates as described in the Pooling and Servicing Agreement referred to
herein.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to the Voting Rights
identified in the agreement. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee and
the Certificate Registrar duly executed by, the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations evidencing the same aggregate
Percentage Interest will be issued to the designated transferee or transferees.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            No transfer of this Certificate shall be made unless that transfer
is made pursuant to an effective registration statement under the 1933 Act and
effective registration or qualification under applicable state securities laws,
or is made in a transaction that does not require such registration or
qualification. In the event that a transfer is to be made without registration
or qualification, the Certificate Registrar shall require, in order to assure
compliance with such laws, that the Certificateholder desiring to effect the
transfer and such Certificateholder's prospective transferee each execute a
representation letter in the form described by the Agreement (as to which, so
long as this Certificate is a Book-Entry Certificate, the representations and
agreements made therein will be deemed to have been made by the prospective
transferor and/or the prospective transferee, as applicable) certifying to the
Certificate Registrar the facts surrounding the transfer. None of the Depositor,
the Certificate Registrar or the Trustee is obligated to register or qualify the
Class of Certificates specified on the face hereof under the 1933 Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of such Certificates without registration or
qualification. Any such Certificateholder desiring to effect such transfer
shall, and does hereby agree to, indemnify the Trustee, the Depositor, the
Certificate Registrar and any Servicer against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and none of the Depositor, the
Servicer, the Trustee, the Certificate Registrar nor any such agent shall be
affected by notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement, subject to certain conditions set forth in Article X of the
Agreement, to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at the Termination Price on the
Optional Termination Date. The exercise of such right will effect early
retirement of the Certificates.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

reasonable wire transfer fee from any payment made by wire transfer.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency

specified on the face hereof (herein called the "Certificates") and representing
the Percentage Interest specified on the face hereof.

            The Class CE Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account

certain expenses incurred, with respect to the Mortgage Loans.

amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee

identified in the agreement. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is

certain limited circumstances, without the consent of the Holders of any of the
Certificates.

or is made in a transaction that does not require such registration or
qualification. In the event that a transfer is to be made without registration
or qualification, the Certificate Registrar shall require, in order to assure
compliance with such laws, either (i) that the Certificateholder desiring to

(ii) unless such transfer is made in reliance upon Rule 144A under the 1933 Act,
that the Depositor and the Certificate Registrar receive an Opinion of Counsel
satisfactory to them that such transfer may be made without such registration or
qualification, which Opinion of Counsel shall not be an expense of the

Trustee, the Depositor, the Certificate Registrar and any Servicer against any
liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans, accounts
or arrangements are invested that are subject to the fiduciary responsibility
provisions of ERISA, Section 4975 of the Code or any materially similar
provisions of applicable federal, state or local law (collectively, "Plans") or
any person who is directly or indirectly purchasing the Certificate or interest
therein on behalf of, as named fiduciary of, as trustee of, or with assets of a
Plan.

or exchange of Certificates, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and none of the Depositor, the
Servicer, the Trustee, the Certificate Registrar nor any such agent shall be
affected by notice to the contrary.

thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to

liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in

Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by

Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made

            All distributions to the Holder of this Certificate under the

wire transfer in immediately available funds to the account of the Person
entitled thereto if such Person shall have so notified the Certificate Registrar

Certificates, or by check mailed by first class mail to the address of the
Person entitled thereto, as such name and address shall appear on the
Certificate Register, provided that the Certificate Registrar may deduct a
reasonable wire transfer fee from any payment made by wire transfer.
Notwithstanding the above, the final distribution on this Certificate will be
made after due notice by the Trustee of the pendency of such distribution and
only upon presentation and surrender of this Certificate at the office or agency
appointed by the Trustee for that purpose as provided in the Agreement.

            This Certificate is one of a duly authorized issue of Certificates
designated as ABFC Asset-Backed Certificates of the Series specified on the face
hereof (herein called the "Certificates") and representing the Percentage
Interest specified on the face hereof.

            The Class P Certificates are limited in right of payment to
Prepayment Charges received on the Mortgage Loans, Originator Prepayment Charge
Payment Amounts and Servicer Prepayment Charge Payment Amounts, all as more
specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Collection Account and the Distribution Account
may be made from time to time for purposes other than distributions to
Certificateholders, such purposes including reimbursement of advances made, or
certain expenses incurred, with respect to the Mortgage Loans.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Servicer, the Trustee and the rights of the Certificateholders
under the Agreement at any time by the Depositor, the Servicer and the Trustee
with the consent of the Holders of Certificates entitled to the Voting Rights
identified in the agreement. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, without the consent of the Holders of any of the
Certificates.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee as provided in the
Agreement, duly endorsed by, or accompanied by an assignment in the form below
or other written instrument of transfer in form satisfactory to the Trustee and
the Certificate Registrar duly executed by, the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
of the same Class in authorized denominations evidencing the same aggregate
Percentage Interest will be issued to the designated transferee or transferees.

            The Certificates are issuable in fully registered form only without
coupons in Classes and denominations representing Percentage Interests specified
in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Certificates are exchangeable for new
Certificates of the same Class in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            No transfer of this Certificate shall be made unless that transfer
is made pursuant to an effective registration statement under the 1933 Act and
effective registration or qualification under applicable state securities laws,
or is made in a transaction that does not require such registration or
qualification. In the event that a transfer is to be made without registration
or qualification, the Certificate Registrar shall require, in order to assure
compliance with such laws, either (i) that the Certificateholder desiring to
effect the transfer and such Certificateholder's prospective transferee each
execute a representation letter in the form described by the Agreement
certifying to the Certificate Registrar the facts surrounding the transfer, or
(ii) unless such transfer is made in reliance upon Rule 144A under the 1933 Act,
that the Depositor and the Certificate Registrar receive an Opinion of Counsel
satisfactory to them that such transfer may be made without such registration or
qualification, which Opinion of Counsel shall not be an expense of the
Depositor, the Trustee or the Certificate Registrar, in their respective
capacities as such. None of the Depositor, the Certificate Registrar or the
Trustee is obligated to register or qualify the Class of Certificates specified
on the face hereof under the 1933 Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of such
Certificates without registration or qualification. Any such Certificateholder
desiring to effect such transfer shall, and does hereby agree to, indemnify the
Trustee, the Depositor, the Certificate Registrar and any Servicer against any
liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

            No transfer of a Certificate or any interest therein may be made to
employee benefit plans and certain other retirement plans and arrangements,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans, accounts
or arrangements are invested that are subject to the fiduciary responsibility
provisions of ERISA, Section 4975 of the Code or any materially similar
provisions of applicable federal, state or local law (collectively, "Plans") or
any person who is directly or indirectly purchasing the Certificate or interest
therein on behalf of, as named fiduciary of, as trustee of, or with assets of a
Plan.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and none of the Depositor, the
Servicer, the Trustee, the Certificate Registrar or any such agent shall be
affected by notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement, subject to certain conditions set forth in Article X of the
Agreement, to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at the Termination Price on the
Optional Termination Date. The exercise of such right will effect early
retirement of the Certificates.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

(ii) unless such transfer is made in reliance upon Rule 144A under the 1933 Act,
that the Depositor and the Certificate Registrar receive an Opinion of Counsel
satisfactory to them that such transfer may be made without such registration or
qualification, which Opinion of Counsel shall not be an expense of the
Depositor, the Trustee or the Certificate Registrar, in their respective
capacities as such. None of the Depositor, the Certificate Registrar or the
Trustee is obligated to register or qualify the Class of Certificates specified
on the face hereof under the 1933 Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of such
Certificates without registration or qualification. Any such Certificateholder
desiring to effect such transfer shall, and does hereby agree to, indemnify the
Trustee, the Depositor, the Certificate Registrar and any Servicer against any
liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

            No transfer of this Certificate or any interest therein may be made
to employee benefit plans and certain other retirement plans and arrangements,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans, accounts
or arrangements are invested that are subject to the fiduciary responsibility
provisions of ERISA, Section 4975 of the Code or any materially similar
provisions of applicable federal, state or local law (collectively, "Plans") or
any person who is directly or indirectly purchasing the Certificate or interest
therein on behalf of, as named fiduciary of, as trustee of, or with assets of a
Plan.

            The Holder of this Certificate, by its acceptance hereof, shall be
deemed for all purposes to have consented to the provisions of Section 5.02 of
the Agreement and to any amendment of the Agreement deemed necessary by counsel
of the Depositor to ensure that the transfer of this Certificate to any Person
other than a Permitted Transferee or any other Person will not cause the Trust
to cease to qualify as five separate REMICs or cause the imposition of a tax
upon the Trust.

            No service charge will be made for any such registration of transfer
or exchange of Certificates, but the Certificate Registrar may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

            The Depositor, the Servicer, the Trustee and the Certificate
Registrar and any agent of the Depositor, the Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and none of the Depositor, the
Servicer, the Trustee, the Certificate Registrar nor any such agent shall be
affected by notice to the contrary.

            The obligations created by the Agreement and the Trust Fund created
thereby shall terminate upon payment to the Certificateholders of all amounts
held by or on behalf of the Trustee and required to be paid to them pursuant to
the Agreement following the earlier of (i) the final payment or other
liquidation (or any advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund, and (ii) the purchase by the party designated in
the Agreement at a price determined as provided in the Agreement from the Trust
Fund of all Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement, subject to certain conditions set forth in Article X of the
Agreement, to purchase from the Trust Fund all Mortgage Loans and all property
acquired in respect of any Mortgage Loan at the Termination Price on the
Optional Termination Date. The exercise of such right will effect early
retirement of the Certificates.

            The recitals contained herein shall be taken as statements of the
Depositor and the Trustee assumes no responsibility for their correctness.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans, accounts

provisions of applicable federal, state or local law (collectively, "Plans") or
any person who is directly or indirectly purchasing the Certificate or interest
therein on behalf of, as named fiduciary of, as trustee of, or with assets of a

affected by notice to the contrary.

thereby shall terminate upon payment to the Certificateholders of all amounts

                ABFC ASSET-BACKED CERTIFICATES, SERIES 2006-OPT1

STATE OF                )
                        ) ss.:
COUNTY OF               )

            The undersigned, being first duly sworn, deposes and says as
follows:

            1. The undersigned is [an officer of] ____________________, the
proposed Transferee of an Ownership Interest in the [Class R][Class R-X]
Certificates (the "Certificate") issued pursuant to the Pooling and Servicing
Agreement, (the "Agreement"), relating to the above-referenced Certificates,
among Asset Backed Funding Corporation, as depositor, Option One Mortgage
Corporation, as servicer, and Wells Fargo Bank, N.A., as trustee (the
"Trustee"). Capitalized terms used, but not defined herein shall have the
meanings ascribed to such terms in the Agreement. The Transferee has authorized
the undersigned to make this affidavit on behalf of the Transferee.

            2. The Transferee is, as of the date hereof, and will be, as of the
date of the Transfer, a Permitted Transferee. The Transferee is acquiring its
Ownership Interest in the Certificates either (i) for its own account or (ii) as
nominee, trustee or agent for another Person and has attached hereto an
affidavit from such Person in substantially the same form as this affidavit. The
Transferee has no knowledge that any such affidavit is false.

            3. The Transferee has been advised of, and understands that (i) a
tax will be imposed on Transfers of the Certificate to Persons that are
Disqualified Organization; (ii) such tax will be imposed on the transferor, or,
if such Transfer is through an agent (which includes a broker, nominee or
middleman) for a Person that is a Disqualified Organization, on the agent; and
(iii) the Person otherwise liable for the tax shall be relieved of liability for
the tax if the subsequent Transferee furnished to such Person an affidavit that
such subsequent Transferee is not a Disqualified Organization and, at the time
of Transfer, such Person does not have actual knowledge that the affidavit is
false.

            4. The Transferee has been advised of, and understands that a tax
will be imposed on a "pass-through entity" holding the Certificate if at any
time during the taxable year of the pass-through entity a Person that is a
Disqualified Organization is the record holder of an interest in such entity.
The Transferee understands that such tax will not be imposed for any period with
respect to which the record holder furnishes to the pass-through entity an
affidavit that such record holder is not a Disqualified Organization and the
pass-through entity does not have actual knowledge that such affidavit is false.
(For this purpose, a "pass-through entity" includes a regulated investment
company, a real estate investment trust or common trust fund, a partnership,
trust or estate, and certain cooperatives and, except as may be provided in
Treasury Regulations, persons holding interests in pass-through entities as a
nominee for another Person.)

            5. The Transferee has reviewed the provisions of Section 5.02(d) of
the Agreement and understands the legal consequences of the acquisition of an
Ownership Interest in the Certificate including, without limitation, the
restrictions on subsequent Transfers and the provisions regarding voiding the
Transfer and mandatory sales. The Transferee expressly agrees to be bound by and
to abide by the provisions of Section 5.02(d) of the Agreement and the
restrictions noted on the face of the Certificate. The Transferee understands
and agrees that any breach of any of the representations included herein shall
render the Transfer to the Transferee contemplated hereby null and void.

            6. The Transferee agrees to require a Transfer Affidavit from any
Person to whom the Transferee attempts to Transfer its Ownership Interest in the
Certificate, and in connection with any Transfer by a Person for whom the
Transferee is acting as nominee, trustee or agent, and the Transferee will not
Transfer its Ownership Interest or cause any Ownership Interest to be
Transferred to any Person that the Transferee knows is not a Permitted
Transferee. In connection with any such Transfer by the Transferee, the
Transferee agrees to deliver to the Trustee a certificate substantially in the
form set forth in this Exhibit L to the Agreement (a "Transferor Certificate")
to the effect that such Transferee has no actual knowledge that the Person to
which the Transfer is to be made is not a Permitted Transferee.

            7. The Transferee does not have the intention to impede the
assessment or collection of any tax legally required to be paid with respect to
the Certificate.

            8. The Transferee's taxpayer identification number is
__________________.

            9. The Transferee is a U.S. Person as defined in Code Section
7701(a)(30).

            10. The Transferee is aware that the Certificate may be a
"noneconomic residual interest" within the meaning of Treasury regulations
promulgated pursuant to the Code and that the transferor of a noneconomic
residual interest will remain liable for any taxes due with respect to the
income on such residual interest, unless no significant purpose of the transfer
was to impede the assessment or collection of tax.

            11. That the Transferee will not cause income from the [Class
R][Class R-X] Certificate to be attributable to a foreign permanent
establishment or fixed base, within the meaning of an applicable income tax
treaty, of the Transferee or any other person.

            12. That, if the Transferee is purchasing the [Class R][Class R-X]
Certificate in a transfer intended to meet the safe harbor provisions of
Treasury Regulations Sections 1.860E-1(c), the Transferee has executed and
attached Attachment A hereto.

            13. The Transferee is not an employee benefit plan that is subject
to ERISA or a plan that is subject to Section 4975 of the Code or a plan or
arrangement subject to any materially similar provisions of applicable federal,
state or local law, nor are we acting on behalf of such a plan.

by its duly authorized officer, duly attested, this ____  day of

anticipated tax liabilities over (b) the present value of the anticipated
savings associated with holding such Certificate, in each case calculated in
accordance with U.S. Treasury Regulations Sections 1.860E-1(c)(7) and (8),

      Transferee's two fiscal years preceding the year of the transfer, the

      any obligation of a person related to the Transferee within the meaning of
      U.S. Treasury Regulations Section 1.860E-1(c)(6)(ii)) in excess of $100
      million and net assets in excess of $10 million;

      rates, prepayment and loss assumptions, expense and reinvestment
      assumptions, tax rates and other factors specific to the Transferee) that
      it has determined in good faith; and

            (v) in the event of any transfer of the [Class R][Class R-X]
      Certificate by the Transferee, the Transferee will require its transferee
      to complete a representation in the form of this Attachment A as a
      condition of the transferee's purchase of the [Class R][Class R-X]

              with a copy of the related Mortgage Note;

       (ii)   the original Mortgage with evidence of recording thereon, and the
              original recorded power of attorney, if the Mortgage was executed
              pursuant to a power of attorney, with evidence of recording
              thereon or, if such Mortgage or power of attorney has been
              submitted for recording but has not been returned from the
              applicable public recording office, has been lost or is not
              otherwise available, a copy of such Mortgage or power of attorney,
              as the case may be, certified to be a true and complete copy of
              the original submitted for recording;

       (iii)  an original Assignment of Mortgage (which may be in blank), in
              form and substance acceptable for recording; provided, however, if
              the related Mortgage has been recorded in the name of Mortgage
              Electronic Registration Systems, Inc. ("MERS") or its designee, no
              Assignment of Mortgage in favor of the Trustee will be required to
              be prepared or delivered and instead, the Servicer shall take all
              actions as are necessary to cause the Trust to be shown as the
              owner of the related Mortgage Loan on the records of MERS for
              purposes of the system of recording transfers of beneficial
              ownership of mortgages maintained by MERS;

       (vi)   the original or copies of each assumption, modification, written
              assurance or substitution agreement, if any.

              The Seller hereby confirms to the Purchaser and the Trustee that
it has caused the appropriate entries to be made in its general accounting
records to indicate that such Additional Group 3 Mortgage Loans have been
transferred to the Trustee and constitute part of the Trust in accordance with
the terms of the Pooling and Servicing Agreement.

              If any of the documents referred to in Section 2.02(ii), (iii) or
(iv) above has as of the Additional Transfer Date been submitted for recording
but either (x) has not been returned from the applicable public recording office
or (y) has been lost or such public recording office has retained the original
of such document, the obligations of the Seller to deliver such documents shall
be deemed to be satisfied upon (1) delivery to the Trustee, no later than the
Additional Transfer Date, of a copy of each such document certified by the
Seller in the case of (x) above or the applicable public recording office in the
case of (y) above to be a true and complete copy of the original that was
submitted for recording and (2) if such copy is certified by the Seller,
delivery to the Trustee, promptly upon receipt thereof of either the original or
a copy of such document certified by the applicable public recording office to
be a true and complete copy of the original. The Seller shall deliver or cause
to be delivered to the Trustee promptly upon receipt thereof any other documents
constituting a part of a Mortgage File received with respect to any Additional
Group 3 Mortgage Loan, including, but not limited to, any original documents
evidencing an assumption or modification of any Additional Group 3 Mortgage
Loan.

              Upon discovery or receipt of notice of any materially defective
document in, or that a document is missing from, a Mortgage File, the Seller
shall have 120 days to cure such defect or deliver such missing document to the
Trustee or 150 days following the Additional Transfer Date, in the case of
missing Mortgages or Assignments of Mortgage (or within 90 days of the earlier
of Seller's discovery or receipt of notification if such defect would cause the
related Additional Group 3 Mortgage Loan not to be a "qualified mortgage" for
REMIC purposes or that the Additional Group 3 Mortgage Loan is defective in a
manner that would cause it to be a "defective obligation" within the meaning of
Treasury regulations relating to REMICs). If the Seller does not cure such
defect or deliver such missing document within such time period, the Seller
shall either repurchase or substitute for such Additional Group 3 Mortgage Loan
in accordance with Section 2.03 of the Pooling and Servicing Agreement.

              The Purchaser hereby acknowledges its acceptance of all right,
title and interest to the Additional Group 3 Mortgage Loans and other property,
now existing and hereafter created, conveyed to it pursuant to Section 2.01.

              The parties hereto intend that the transaction set forth herein be
a sale by the Seller to the Purchaser of all the Seller's right, title and
interest in and to the Additional Group 3 Mortgage Loans and other property
described above. In the event the transaction set forth herein is deemed not to
be a sale, the Seller hereby grants to the Purchaser a security interest in all
of the Seller's right, title and interest in, to and under the Additional Group
3 Mortgage Loans and other property described above, whether now existing or
hereafter created, to secure all of the Seller's obligations hereunder; and this
Agreement shall constitute a security agreement under applicable law.

       Section 2.03 Payment of Additional Group 3 Mortgage Loans Purchase Price.

              In consideration of the sale of the Additional Group 3 Mortgage
Loans from the Seller to the Purchaser on the Additional Transfer Date, the

                                  ARTICLE III.

               REPRESENTATIONS AND WARRANTIES; REMEDIES FOR BREACH

       Section 3.01 Seller Representations and Warranties Relating to the
Additional Group 3 Mortgage Loans.

              The Seller and the Purchaser understand, acknowledge and agree
that, the representations and warranties set forth in this Section 3.01 are made
as of the Additional Transfer Date or as of the date specifically provided
herein.

              The Seller hereby represents and warrants to the Purchaser with
respect to the Additional Group 3 Mortgage Loans that each of the
representations and warranties made by the Seller pursuant to Section 3.01 of
the Mortgage Loan Purchase Agreement, dated July 1, 2006 (the "MLPA") between
the Seller and the Purchaser, are true and correct as of the Additional Transfer
Date; provided, however, that any references in the MLPA to Cut-off Date shall
be a reference to Subsequent Cut-off Date herein, that any references in the
MLPA to Mortgage Loan shall be a reference to Additional Group 3 Mortgage Loan
herein and that any references in the MLPA to Closing Date shall be a reference
to Additional Transfer Date herein.

       Section 3.02 Seller Representations and Warranties Relating to the
Seller.

              The Seller represents, warrants and covenants to the Purchaser
that each of the representations and warranties made by the Seller pursuant to
Section 3.02 of the MLPA are true and correct as of the Additional Transfer
Date; provided, however, that any references in the MLPA to Cut-off Date shall
be a reference to Subsequent Cut-off Date, that any references in the MLPA to
Mortgage Loan shall be a reference to Additional Group 3 Mortgage Loan and that
any references in the MLPA to Closing Date shall be a reference to Additional
Transfer Date.

       Section 3.03 Remedies for Breach of Representations and Warranties.

              It is understood and agreed that the representations and
warranties set forth in Subsections 3.01 and 3.02 of the MLPA shall survive the
sale of the Additional Group 3 Mortgage Loans to the Purchaser and shall inure
to the benefit of the Purchaser, notwithstanding any restrictive or qualified
endorsement on any Mortgage Note or Assignment or the examination or lack of
examination of any Mortgage File. With respect to the representations and
warranties contained in the MLPA that are made to the knowledge or the best
knowledge of the Seller, or as to which the Seller has no knowledge, if it is
discovered that the substance of any such representation and warranty is
inaccurate and the inaccuracy materially and adversely affects the value of the
related Additional Group 3 Mortgage Loan, or the interest therein of the
Purchaser or the Purchaser's assignee, designee or transferee, then
notwithstanding the Seller's lack of knowledge with respect to the substance of
such representation and warranty being inaccurate at the time the representation
and warranty was made, such inaccuracy shall be deemed a breach of the
applicable representation and warranty and the Seller shall take such action
described in the following paragraphs of this Section 3.03 in respect of such
Additional Group 3 Mortgage Loan.

              Upon discovery by either the Seller or the Purchaser of a breach
of any of the foregoing representations and warranties that materially and
adversely affects the value of the Additional Group 3 Mortgage Loans or the
interest of the Purchaser (or which materially and adversely affects the
interests of the Purchaser in the related Additional Group 3 Mortgage Loan in
the case of a representation and warranty relating to a particular Additional
Group 3 Mortgage Loan), the party discovering such breach shall give prompt
written notice to the other. Subject to the second paragraph of Section 3.01 of
the MLPA, within 90 days of the earlier of its discovery or its receipt of
notice of any breach of a representation or warranty, the Seller shall promptly
cure such breach in all material respects, or in the event such breach cannot be
cured, the Seller shall repurchase the affected Additional Group 3 Mortgage Loan
or cause the removal of such Mortgage Loan from the Trust Fund and substitute
for it one or more Eligible Substitute Mortgage Loans, in either case, in
accordance with Section 2.03 of the Pooling and Servicing Agreement.

              It is understood and agreed that the representations and
warranties set forth in Sections 3.01 and 3.02 of the MLPA shall survive
delivery of the respective Mortgage Files to the Trustee on behalf of the
Purchaser.

              It is understood and agreed that the obligations of the Seller set
forth in this Section 3.03 to cure, repurchase and substitute for a defective
Additional Group 3 Mortgage Loan constitute the sole remedy of the Purchaser
respecting a missing or defective document or a breach of the representations
and warranties contained in Section 3.01 or 3.02 of the MLPA.

                                   ARTICLE IV.

                               SELLER'S COVENANTS

       Section 4.01 Covenants of the Seller. The Seller hereby covenants that
except for the transfer hereunder, the Seller will not sell, pledge, assign or
transfer to any other Person, or grant, create, incur or assume or suffer to
exist any lien on any Additional Group 3 Mortgage Loan, or any interest therein;
the Seller will notify the Trustee, as assignee of the Purchaser, of the
existence of any lien on any Additional Group 3 Mortgage Loan immediately upon
discovery thereof, and the Seller will defend the right, title and interest of
the Trust, as assignee of the Purchaser, in, to and under the Additional Group 3
Mortgage Loans, against all claims of third parties claiming through or under
the Seller; provided, however, that nothing in this Section 4.01 shall prevent
or be deemed to prohibit the Seller from suffering to exist upon any of the
Additional Group 3 Mortgage Loans, any liens for municipal or other local taxes
and other governmental charges if such taxes or governmental charges shall not
at the time be due and payable or if the Seller shall currently be contesting
the validity thereof in good faith by appropriate proceedings and shall have set
aside on its books adequate reserves with respect thereto.

                                   ARTICLE V.

                                   [RESERVED]

                                   ARTICLE VI

                                   TERMINATION

       Section 6.01 Termination. The respective obligations and responsibilities
of the Seller and the Purchaser created hereby shall terminate, except for the

Trust as provided in Article X of the Pooling and Servicing Agreement.

                                  ARTICLE VII.

                            MISCELLANEOUS PROVISIONS

       Section 7.01 Amendment. This Agreement may be amended from time to time
by the Seller and the Purchaser, by written agreement signed by the Seller and
the Purchaser.

       Section 7.02 Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York and the
obligations, rights and remedies of the parties hereunder shall be determined in
accordance with such laws.

       Section 7.03 Notices. All demands, notices and communications hereunder
shall be in writing and shall be deemed to have been duly given if personally
delivered at or mailed by registered mail, postage prepaid, addressed as
follows: (i) if to the Seller, Bank of America, National Association, 214 North
Tryon Street, Charlotte, North Carolina 28255, Attention: General Counsel or
such other address as may hereafter be furnished to the Purchaser in writing by
the Seller and (ii) if to the Purchaser, Asset Backed Funding Corporation, 214

Seller in writing by the Purchaser.

       Section 7.04 Severability of Provisions. If any one or more of the
covenants, agreements, provisions of terms of this Agreement shall be held
invalid for any reason whatsoever, then such covenants, agreements, provisions
or terms shall be deemed severable from the remaining covenants, agreements,
provisions or terms of this Agreement and shall in no way affect the validity of
enforceability of the other provisions of this Agreement.

       Section 7.05 Counterparts. This Agreement may be executed in one or more
counterparts and by the different parties hereto on separate counterparts, each
of which, when so executed, shall be deemed to be an original and such
counterparts, together, shall constitute one and the same agreement.

       Section 7.06 Further Agreements. The Purchaser and the Seller each agree
to execute and deliver to the other such additional documents, instruments or
agreements as may be necessary or reasonable and appropriate to effectuate the
purposes of this Agreement or in connection with the issuance of any Series of
Certificates representing interests in the Additional Group 3 Mortgage Loans.

       Section 7.07 Intention of the Parties. It is the intention of the parties
that the Purchaser is purchasing, and the Seller is selling, the Additional
Group 3 Mortgage Loans rather than pledging the Additional Group 3 Mortgage
Loans to secure a loan by the Purchaser to the Seller. Accordingly, the parties
hereto each intend to treat the transaction for federal income tax purposes and
all other purposes as a sale by the Seller, and a purchase by the Purchaser, of
the Additional Group 3 Mortgage Loans. The Purchaser will have the right to
review the Additional Group 3 Mortgage Loans and the related Mortgage Files to
determine the characteristics of the Additional Group 3 Mortgage Loans which
will affect the federal income tax consequences of owning the Additional Group 3
Mortgage Loans and the Seller will cooperate with all reasonable requests made
by the Purchaser in the course of such review.

       Section 7.08 Successors and Assigns; Assignment of Purchase Agreement.
This Agreement shall bind and inure to the benefit of and be enforceable by the
Seller, the Purchaser and the Trustee.

       The obligations of the Seller under this Agreement cannot be assigned or
delegated to a third party without the consent of the Purchaser which consent
shall be at the Purchaser's sole discretion, except that the Purchaser
acknowledges and agrees that the Seller may assign its obligations hereunder to
any Person into which the Seller is merged or any corporation resulting from any
merger, conversion or consolidation to which the Seller is a party or any Person
succeeding to the business of the Seller. The parties hereto acknowledge that
the Purchaser is acquiring the Additional Group 3 Mortgage Loans for the purpose
of contributing them to a trust that will issue a series of Certificates
representing undivided interests in such Additional Group 3 Mortgage Loans. As
an inducement to the Purchaser to purchase the Additional Group 3 Mortgage
Loans, the Seller acknowledges and consents to the assignment by the Purchaser
to the Trustee of all of the Purchaser's rights against the Seller pursuant to
this Agreement insofar as such rights relate to Additional Group 3 Mortgage
Loans transferred to the Trustee and to the enforcement or exercise of any right
or remedy against the Seller pursuant to this Agreement by the Trustee. Such
enforcement of a right or remedy by the Trustee shall have the same force and
effect as if the right or remedy had been enforced or exercised by the Purchaser
directly.

       Section 7.09 Survival. The representations and warranties incorporated by
reference in Sections 3.01 and 3.02 and the provisions of Article V hereof shall
survive the purchase of the Additional Group 3 Mortgage Loans hereunder.

              IN WITNESS WHEREOF, the Seller and the Purchaser have caused their
names to be signed to this Additional Mortgage Loan Purchase Agreement by their
respective officers thereunto duly authorized as of the day and year first above
written.
