(1)    The Class F Interest will have a principal balance equal to the
       principal balance of the R-1-1-I and R-1-1-S Interests.

(2)    A rate equal to the weighted average of the pass-through rates of the
      R-1-1-I and R-1-1-S Interests (the "Loan Group [1] Net Rate Cap").

(3)    With respect to the Variable Interests, each REMIC 2 Interest having an
      "R-2-A-" designation (each, an "R-2-A Interest") will have a principal
      balance initially equal to [0.9]% of the Subordinate Component Balance
      ("SCB") of its Corresponding Loan Group. Each REMIC 2 Interest having an
      "R-2-B-" designation (each, an "R-2-B Interest") will have a principal
      balance initially equal to [0.1]% of the SCB of its Corresponding Loan
      Group. Each REMIC 2 Interest having an "R-2-C-" designation (each, an
      "R-2-C Interest") will have a principal balance initially equal to
      [0.9]% of the Adjusted Subordinated Component Balance ("ASCB") of its
      Corresponding Loan Group. Each REMIC 2 Interest having an "R-2-D-"
      designation (each, an "R-2-D Interest") will have a principal balance
      initially equal to [0.1]% of the ASCB of its Corresponding Loan Group.
      The initial principal balance of each REMIC 2 Interest having an
      "R-2-E-" designation (each, an "R-2-E Interest") will equal the excess
      of its Corresponding Loan Group over the initial aggregate principal
      balances of the R-2-A, R-2-B, R-2-C and R-2-D Interests corresponding to
      such Loan Group.

(4)    A rate equal to the weighted average of the pass-through rates of the
      R-1-2-I and R-1-2-S Interests (the "Loan Group [2] Net Rate Cap").

(5)    A rate equal to the weighted average of the pass-through rates of the
      R-1-3-I and R-1-3-S Interests (the "Loan Group [3] Net Rate Cap").

(6)    The R-2-PF Interest is entitled to all Prepayment Charges collected with
      respect to the Mortgage Loans in Group [1]. It pays no interest.

(7)    The R-2-PV Interest is entitled to all Prepayment Charges collected with
      respect to the Mortgage Loans in Loan Group [2] and Loan Group [3]. It
      pays no interest.

(8)    The R-2-R Interest is the sole class of residual interest in REMIC 2. It
      has no principal balance and pays no principal or interest.

(9)    This REMIC 2 Interest pays no principal.

(10)   This REMIC 2 Interest is entitiled to all amounts payable with respect
      to the R-1-XF Interest.

<PAGE>



(11)   This REMIC 2 Interest is entitiled to all amounts payable with respect
      to the R-1-XV Interest.

           On each Distribution Date, the Interest Funds and the Principal
Distribution Amounts payable with respect to the REMIC 1 Interests shall be
payable with respect to the REMIC 2 Interests in the following manner:

      (1) Interest. Interest is to be distributed with respect to each REMIC 2
Interest at the rate, or according to the formulas, described above.

      (2) Principal. All Principal Distribution Amounts arising with respect
to Loan Group [1] shall be allocated to the Fixed Interests.

      (3) Principal if no Cross-Over Situation Exists. If no Cross-Over
Situation exists with respect to any Variable Interest, then the Principal
Distribution Amounts payable with respect to each Variable Loan Group will be
payable: first to cause the Variable Loan Group's corresponding R-2-A, R-2-B,
R-2-C and R-2-D Interests to equal, respectively, [0.9]% of the SCB, [0.1]% of
the SCB, [0.9]% of the ASCB and [0.1]% of the ASCB, of the Corresponding Loan
Group, and then to the corresponding R-2-E Interest.

      (4) Principal if a Cross-Over Situation Exists. If a Cross-Over
Situation exists with respect to the R-2-A and R-2-B Interests then:

      (a) if the Calculation Rate in respect of the outstanding R-2-A and
R-2-B Interests is less than the Adjustable Rate Subordinate Net Rate Cap,
Principal Relocation Payments will be made proportionately to the outstanding
R-2-A Interests prior to any other principal distributions from each such
Variable Loan Group; and

      (b) if the Calculation Rate in respect of the outstanding R-2-A and
R-2-B Interests is greater than the Adjustable Rate Subordinate Net Rate Cap,
Principal Relocation Payments will be made proportionately to the outstanding
R-2-B Interests prior to any other principal distributions from each such
Variable Loan Group.

In each case, Principal Relocation Payments will be made so as to cause the
Calculation Rate in respect of the outstanding R-2-A and R-2-B Interests to
equal the Adjustable Rate Subordinate Net Rate Cap. With respect to each
Variable Loan Group, if (and to the extent that) the sum of (a) the principal
payments comprising the Principal Distribution Amount payable for the related
Distribution Date and (b) the Realized Losses, are insufficient to make the
necessary reductions of principal on the R-2-A and R-2-B Interests, then
interest will be added to the Variable Loan Group's R-2-E Interest.


                                      5
<PAGE>



(c) The outstanding aggregate R-2-A and R-2-B Interests for both Variable Loan
Groups will not be reduced below 1 percent of the excess of (i) the aggregate
outstanding Stated Principal Balances of all Variable Loan Groups as of the
end of any Due Period over (ii) the Senior Certificates related to the
Variable Loan Groups as of the related Distribution Date (after taking into
account distributions of principal on such Distribution Date).

If (and to the extent that) the limitation in paragraph (c) prevents the
distribution of principal to the R-2-A and R-2-B Interests of a Variable Loan
Group, and if the Variable Loan Group's corresponding R-2-E Interest has
already been reduced to zero, then the excess principal from that Variable
Loan Group will be paid to the R-2-E Interest of the other Variable Loan
Group, the aggregate R-2-A and R-2-B Interests of which are less than one
percent of the Subordinate Component Balance. If the Variable Loan Group of
the corresponding R-2-E Interest that receives such payment has a Group Net
Rate Cap below the Group Net Rate Cap of the Variable Loan Group making the
payment, then the payment will be treated by REMIC 2 as a Realized Loss.
Conversely, if the Variable Loan Group of the R-2-E Interest that receives
such payment has a Group Net Rate Cap above the Group Net Rate Cap of the
Variable Loan Group making the payment, then the payment will be treated by
REMIC 2 as a reimbursement for prior Realized Losses.

If a Cross-Over Situation exists with respect to the R-2-C and R-2-D Interests
then:

      (d) if the Calculation Rate in respect of the outstanding R-2-C and
R-2-D Interests is less than the Adjusted Subordinate Net Rate Cap, Principal
Relocation Payments will be made proportionately to the R-2-C Interests prior
to any other principal distributions from each such Variable Loan Group; and

      (e) if the Calculation Rate in respect of the outstanding R-2-C and
R-2-D Interests is greater than the Adjusted Subordinate Net Rate Cap,
Principal Relocation Payments will be made proportionately to the outstanding
R-2-D Interests prior to any other principal distributions from each such
Variable Loan Group.

In each case, Principal Relocation Payments will be made so as to cause the
Calculation Rate in respect of the outstanding R-2-C and R-2-D Interests to
equal the Adjusted Subordinate Net Rate Cap. With respect to each Variable
Loan Group, if (and to the extent that) the sum of (a) the principal payments
comprising the Principal Distribution Amount payable for the related
Distribution Date and (b) the Realized Losses, are insufficient to make the
necessary reductions of principal on the R-2-C and R-2-D Interests, then
interest will be added to the Variable Loan Group's R-2-E Interest.

      (f) The outstanding aggregate R-2-C and R-2-D Interests for all Variable
Loan Groups will not be reduced below 1 percent of the excess of (i) the
aggregate outstanding Stated Principal Balances of all Variable Loan Groups as
of the end of any Due Period over (ii) the Senior Certificates related to the
Variable Loan Groups as of the related Distribution Date (after taking into
account distributions of principal on such Distribution Date).

If (and to the extent that) the limitation in paragraph (f) prevents the
distribution of principal to the R-2-C and R-2-D Interests of a Variable Loan
Group, and if the Variable Loan Group's R-2-


                                       6
<PAGE>


E Interest has already been reduced to zero, then the excess principal from
that Variable Loan Group will be paid to the R-2-E Interests of the other
Variable Loan Group, the aggregate R-2-C and R-2-D Interests of which are less
than one percent of the Adjusted Subordinate Component Balance. If the
Variable Loan Group of the R-2-E Interest that receives such payment has a
Group Net Rate Cap below the Group Net Rate Cap of the Variable Loan Group
making the payment, then the payment will be treated by REMIC 2 as a Realized
Loss. Conversely, if the Variable Loan Group of the R-2- E Interest that
receives such payment has a Group Net Rate Cap above the Group Net Rate Cap of
the Variable Loan Group making the payment, then the payment will be treated
by REMIC 2 as a reimbursement for prior Realized Losses.

(2)    The Class [CF] and Class [CV] Certificates will have Certificate
      Principal Balances equal to the Fixed Rate Overcollateralized Amount and
      Adjustable Rate Overcollateralized Amount, respectively.
(3)    For each Interest Accrual Period the Class [CF] Certificates are
      entitled to an amount (the "Class [CF] Distributable Amount") equal to

      Rate of the Class [CF] Certificates shall be a rate sufficient to
      entitle it to all interest accrued on the REMIC 1 Group [1] "I" and "S"
      Interests less the interest accrued on the other F Class interests
      issued by the Master REMIC. The Class [CF] Distributable Amount for any

      Mortgage Loans.
(4)    For each Interest Accrual Period the Class [CV] Certificates are
      entitled to an amount (the "Class [CV] Distributable Amount") equal to
      the sum of (a) the interest payable on the R-3-XV Interests and (b) a
      specified portion of the interest on the REMIC 1 Group [2] and Group [3]
      "I" and "S" Interests equal to the excess of the Loan Group [2]/3 Net
      Rate Cap over the product of two and the weighted average interest rate
      of the REMIC 3 Regular Interests having an "V" designated in the column
      entitled "REMIC 3 Interests" (other than the R-3-PV and R-3-XV
      Interests) with each such Class other than the R-3-V-Accrual Interest,
      subject to a cap equal to the Pass-Through Rate of the Corresponding
      Master REMIC Class and the R-3-V-Accrual Interest subject to a cap of
      [0.00]%. The Pass-Through Rate of the Class [CV] Certificates shall be a
       rate sufficient to entitle it to all interest accrued on the REMIC 1
      Group [2] and Group [3] "I" and "S" Interests less the interest accrued
      on the other V Class interests issued by the Master REMIC . The Class
      [CV] Distributable Amount for any Distribution Date is payable from
      current interest on the Group [2] and Group [3] Mortgage Loans.
(5)    For each Distribution Date the Class [PF] and Class [PV] Certificates
      are entitled to all Prepayment Charges distributed with respect to the
      R-3-PF and R-3-PV Interests, respectively.
(6)    The Class A-R Certificates represent the sole class of residual interest
      in each REMIC created hereunder. The Class A-R Certificates are not
      entitled to distributions of interest.

            The foregoing REMIC structure is intended to cause all of the cash
from the Mortgage Loans to flow through to the Master REMIC as cash flow on a
REMIC regular interest, without creating any shortfall--actual or potential
(other than for credit losses) to any REMIC regular interest. It is not
intended that the Class A-R be entitled to any cash flows pursuant to this
agreement except as provided in Sections 4.02(a)(1)(ii) and (iv)(y) hereunder,
(that is, its entitlement to $[100] in the waterfall).

<PAGE>

            effect the assignment of and transfer to the assignee thereof,
            under the Mortgage to which such assignment relates);

                  (iv) the original recorded assignment or assignments of the
            Mortgage or a copy of such assignments, with recording
            information, together with all interim recorded assignments of

            In addition, in connection with the assignment of any MERS

expense, the MERS(R) System to indicate (and provide evidence to the Trustee
that it has done so) that such Mortgage Loans have been assigned by such
Seller to the Trustee in accordance with this Agreement for the benefit of the
Certificateholders by including (or deleting, in the case of Mortgage Loans
which are repurchased in accordance with this Agreement) in such computer
files (a) the code "[IDENTIFY TRUSTEE SPECIFIC CODE]" in the field "[IDENTIFY
THE FIELD NAME FOR TRUSTEE]" which identifies the Trustee and (b) the code
"[IDENTIFY SERIES SPECIFIC CODE NUMBER]" in the field "Pool Field" which
identifies the series of the Certificates issued in connection with such

permit the Master Servicer to, and the Master Servicer agrees that it will
not, alter the codes referenced in this paragraph with respect to any Mortgage
Loan during the term of this Agreement unless and until such Mortgage Loan is
repurchased in accordance with the terms of this Agreement.

            In the event that in connection with any Mortgage Loan that is not
a MERS Mortgage Loan a Seller cannot deliver the original recorded Mortgage or
all interim recorded assignments of the Mortgage satisfying the requirements
of clause (ii), (iii) or (iv) concurrently with the execution and delivery
hereof, such Seller shall deliver or cause to be delivered to the Co-Trustee a
true copy of such Mortgage and of each such undelivered interim assignment of
the Mortgage each certified by such Seller, the applicable title company,
escrow agent or attorney, or the originator of such Mortgage, as the case may
be, to be a true and complete copy of the original Mortgage or assignment of
Mortgage submitted for recording. For any such Mortgage Loan that is not a
MERS Mortgage Loan each Seller shall promptly deliver or cause to be delivered
to the Co-Trustee such original Mortgage and such assignment or assignments
with evidence of recording indicated thereon upon receipt thereof from the
public recording official, or a copy thereof, certified, if appropriate, by
the relevant recording office, but in no event shall



                                      70
<PAGE>



any such delivery be made later than [270] days following the Closing Date;
provided that in the event that by such date such Seller is unable to deliver
or cause to be delivered each such Mortgage and each interim assignment by
reason of the fact that any such documents have not been returned by the
appropriate recording office, or, in the case of each interim assignment,
because the related Mortgage has not been returned by the appropriate
recording office, such Seller shall deliver or cause to be delivered such
documents to the Co-Trustee as promptly as possible upon receipt thereof. If
the public recording office in which a Mortgage or interim assignment thereof
is recorded retains the original of such Mortgage or assignment, a copy of the
original Mortgage or assignment so retained, with evidence of recording
thereon, certified to be true and complete by such recording office, shall
satisfy a Seller's obligations in Section 2.01. If any document submitted for
recording pursuant to this Agreement is (x) lost prior to recording or
rejected by the applicable recording office, the applicable Seller shall
immediately prepare or cause to be prepared a substitute and submit it for
recording, and shall deliver copies and originals thereof in accordance with
the foregoing or (y) lost after recording, the applicable Seller shall deliver
to the Co-Trustee a copy of such document certified by the applicable public
recording office to be a true and complete copy of the original recorded
document. Each Seller shall promptly forward or cause to be forwarded to the
Co-Trustee (x) from time to time additional original documents evidencing an
assumption or modification of a Mortgage Loan and (y) any other documents
required to be delivered by the Depositor or the Master Servicer to the
Co-Trustee within the time periods specified in this Section 2.01.

            With respect to each Mortgage Loan other than a MERS Mortgage Loan
as to which the related Mortgaged Property and Mortgage File are located in
(a) the State of California or (b) any other jurisdiction under the laws of
which the recordation of the assignment specified in clause (iii) above is not
necessary to protect the Trustee's and the Certificateholders' interest in the
related Mortgage Loan, as evidenced by an Opinion of Counsel delivered by
[CHL] to the Trustee and a copy to the Rating Agencies, in lieu of recording
the assignment specified in clause (iii) above, the applicable Seller may
deliver an unrecorded assignment in blank, in form otherwise suitable for
recording to the Co-Trustee; provided that if the related Mortgage has not
been returned from the applicable public recording office, such assignment, or
any copy thereof, of the Mortgage may exclude the information to be provided
by the recording office. As to any Mortgage Loan other than a MERS Mortgage
Loan, the procedures of the preceding sentence shall be applicable only so
long as the related Mortgage File is maintained in the possession of the
Co-Trustee in the State or jurisdiction described in such sentence. In the
event that with respect to Mortgage Loans other than MERS Mortgage Loans (i)
any Seller, the Depositor, the Master Servicer or the NIM Insurer gives
written notice to the Trustee that recording is required to protect the right,
title and interest of the Trustee on behalf of the Certificateholders in and
to any Mortgage Loan, (ii) a court recharacterizes any sale of the Mortgage
Loans as a financing, or (iii) as a result of any change in or amendment to
the laws of the State or jurisdiction described in the first sentence of this
paragraph or any applicable political subdivision thereof, or any change in
official position regarding application or interpretation of such laws,
including a holding by a court of competent jurisdiction, such recording is so
required, the Co-Trustee shall complete the assignment in the manner specified
in clause (iii) of the second paragraph of this Section 2.01(g) and [CHL]
shall submit or cause to be submitted for recording as specified above or,
should [CHL] fail to perform such obligations, the Trustee shall cause the
Master Servicer, at the Master Servicer's expense, to cause each such
previously unrecorded assignment to be submitted for recording as specified
above. In the event a Mortgage File is released to the

Master Servicer as a result of the Master Servicer's having completed a
Request for Document Release, the Trustee shall complete the assignment of the
related Mortgage in the manner specified in clause (iii) of the second
paragraph of this Section 2.01(g).

            So long as the Co-Trustee or its agent maintains an office in the
State of California, the Co-Trustee or its agent shall maintain possession of
and not remove or attempt to remove from the State of California any of the
Mortgage Files as to which the related Mortgaged Property is located in such
State. In the event that a Seller fails to record an assignment of a Mortgage
Loan as herein provided within [90] days of notice of an event set forth in
clause (i), (ii) or (iii) of the above paragraph, the Master Servicer shall
prepare and, if required hereunder, file such assignments for recordation in
the appropriate real property or other records office. Each Seller hereby
appoints the Master Servicer (and any successor servicer hereunder) as its
attorney-in-fact with full power and authority acting in its stead for the
purpose of such preparation, execution and filing.

            In the case of Mortgage Loans that become the subject of a
Principal Prepayment between the Closing Date (in the case of Initial Mortgage
Loans) or related Subsequent Transfer Date (in the case of Subsequent Mortgage
Loans) and the Cut-off Date, [CHL] shall deposit or cause to be deposited in
the Certificate Account the amount required to be deposited therein with
respect to such payment pursuant to Section 3.05 hereof.

            Notwithstanding anything to the contrary in this Agreement, within
[thirty] days after the Closing Date (in the case of Initial Mortgage Loans)
or within [twenty] days after the related Subsequent Transfer Date (in the
case of Subsequent Mortgage Loans), [CHL] (on behalf of each Seller) shall
either (i) deliver to the Co-Trustee the Mortgage File as required pursuant to
this Section 2.01 for each Delay Delivery Mortgage Loan or (ii) (A) repurchase
the Delay Delivery Mortgage Loan or (B) substitute the Delay Delivery Mortgage
Loan for a Replacement Mortgage Loan, which repurchase or substitution shall
be accomplished in the manner and subject to the conditions set forth in
Section 2.03, provided that if [CHL] fails to deliver a Mortgage File for any
Delay Delivery Mortgage Loan within the period provided in the prior sentence,
the cure period provided for in Section 2.02 or in Section 2.03 shall not
apply to the initial delivery of the Mortgage File for such Delay Delivery
Mortgage Loan, but rather [CHL] shall have [five] Business Days to cure such
failure to deliver. [CHL] shall promptly provide each Rating Agency with
written notice of any cure, repurchase or substitution made pursuant to the
proviso of the preceding sentence. On or before the [thirtieth] day (or if
such [thirtieth] day is not a Business Day, the succeeding Business Day) after
the Closing Date (in the case of Initial Mortgage Loans) or within [twenty]
days after the related Subsequent Transfer Date (in the case of Subsequent
Mortgage Loans), the Trustee shall, in accordance with the provisions of
Section 2.02, send a Delay Delivery Certification substantially in the form
annexed hereto as Exhibit G-3 (with any applicable exceptions noted thereon)
for all Delay Delivery Mortgage Loans delivered within [thirty] days after
such date. The Trustee will promptly send a copy of such Delay Delivery
Certification to each Rating Agency.

            The Trustee agrees to execute and deliver on the Closing Date to
the Depositor, the Master Servicer and [CHL] (on behalf of each Seller) an
Initial Certification substantially in the form annexed hereto as Exhibit G-1
to the effect that, as to each Initial Mortgage Loan listed in the Mortgage
Loan Schedule (other than any Initial Mortgage Loan paid in full or any
Initial Mortgage Loan specifically identified in such certification as not
covered by such certification), the documents described in Section 2.01(g)(i)
and, in the case of each Initial Mortgage Loan that is not a MERS Mortgage
Loan, the documents described in Section 2.01(g)(iii) with respect to such
Initial Mortgage Loans as are in the Co-Trustee's possession and based on its
review and examination and only as to the foregoing documents, such documents
appear regular on their face and relate to such Initial Mortgage Loan. The
Trustee agrees to execute and deliver within [30] days after the Closing Date
to the Depositor, the Master Servicer and [CHL] (on behalf of each Seller) an
Interim Certification substantially in the form annexed hereto as Exhibit G-2
to the effect that, as to each Initial Mortgage Loan listed in the Mortgage
Loan Schedule (other than any Initial Mortgage Loan paid in full or any
Initial Mortgage Loan specifically identified in such certification as not
covered by such certification) all documents required to be delivered to the

Trustee shall deliver to the Depositor, the Master Servicer and [CHL] (on
behalf of each Seller) a Delay Delivery Certification with respect to the

G-3, with any applicable exceptions noted thereon. The Co-Trustee or the
Trustee, as applicable, shall be under no duty or obligation to inspect,
review or examine such documents, instruments, certificates or other papers to
determine that the same are genuine, enforceable or appropriate for the
represented purpose or that they have actually been recorded in the real
estate records or that they are other than what they purport to be on their
face.

            Not later than [180] days after the Closing Date, the Trustee
shall deliver to the Depositor, the Master Servicer and [CHL] (on behalf of
each Seller), and to any Certificateholder that so requests, a Final

            In connection with the Trustee's completion and delivery of such
Final Certification, the Co-Trustee, at the Trustee's direction, shall review
each Mortgage File with respect to the Initial Mortgage Loans to determine
that such Mortgage File contains the following documents:

                  (i) the original Mortgage Note, endorsed by manual or
            facsimile signature in blank in the following form: "Pay to the
            order of ________________ without recourse", with all intervening
            endorsements that show a complete chain of endorsement from the
            originator to the Person endorsing the Mortgage Note (each such
            endorsement being sufficient to transfer all right, title and
            interest of the party so endorsing, as noteholder or assignee
            thereof, in and to that Mortgage Note), or, if the original
             Mortgage Note has been lost or destroyed and not replaced, an
            original lost note affidavit, stating that the original Mortgage
            Note was lost or destroyed, together with a copy of the related
            Mortgage Note and all such intervening;

                  (ii) in the case of each Initial Mortgage Loan that is not a
            MERS Mortgage Loan, the original recorded Mortgage or a copy of
            such Mortgage, with recording information, and in the case of each
             Initial Mortgage Loan that is a MERS Mortgage Loan, the original
            Mortgage or a copy of such Mortgage, with recording information,
            noting the presence of the MIN of the Initial Mortgage Loan and
            language indicating that the Mortgage Loan is a MOM Loan if the
            Initial Mortgage Loan is a MOM Loan, with evidence of recording
            indicated thereon, or a copy of the Mortgage certified by the
            public recording office in which Mortgage has been recorded;

                  (iii) in the case of each Initial Mortgage Loan that is not
            a MERS Mortgage Loan, a duly executed assignment of the Mortgage
            or a copy thereof with recording information, in either case, in
             the form permitted by Section 2.01;

                  (iv) the original recorded assignment or assignments of the
            Mortgage or a copy of such assignments, with recording
            information, together with all interim recorded assignments of
            such Mortgage or a copy of such assignments, with recording
            information (in each case noting the presence of a MIN in the case
            of each MERS Mortgage Loan);

                  (v) the original or copies of each assumption, modification,
            written assurance or substitution agreement, if any; and

                  (vi) the original or duplicate original lender's title
            policy or a copy of lender's title policy or a printout of the
            electronic equivalent and all riders thereto.

            If, in the course of such review, the Co-Trustee finds any
document or documents constituting a part of such Mortgage File that do not
meet the requirements of clauses (i)-(iv) and (vi) above, the Trustee shall
include such exceptions in such Final Certification (and the Trustee shall
state in such Final Certification whether any Mortgage File does not then
include the original or duplicate original lender's title policy or a printout
of the electronic equivalent and all



                                      74

riders thereto). If the public recording office in which a Mortgage or
assignment thereof is recorded retains the original of such Mortgage or
assignment, a copy of the original Mortgage or assignment so retained, with
evidence of recording thereon, certified to be true and complete by such
recording office, shall be deemed to satisfy the requirements of clause (ii),
(iii) or (iv) above, as applicable. [CHL] shall promptly correct or cure such
defect referred to above within [90] days from the date it was so notified of
such defect and, if [CHL] does not correct or cure such defect within such
period, [CHL] shall either (A) if the time to cure such defect expires prior
to the end of the second anniversary of the Closing Date, substitute for the
related Initial Mortgage Loan a Replacement Mortgage Loan, which substitution
shall be accomplished in the manner and subject to the conditions set forth in
Section 2.03, or (B) purchase such Initial Mortgage Loan from the Trust Fund
within [90] days from the date [CHL] was notified of such defect in writing at
the Purchase Price of such Initial Mortgage Loan; provided that any such
substitution pursuant to (A) above or repurchase pursuant to (B) above shall
not be effected prior to the delivery to the Trustee of the Opinion of Counsel
required by Section 2.05 hereof and any substitution pursuant to (A) above
shall not be effected prior to the additional delivery to the Co-Trustee of a
Request for File Release. No substitution will be made in any calendar month
after the Determination Date for such month. The Purchase Price for any such
Initial Mortgage Loan shall be deposited by [CHL] in the Certificate Account
and, upon receipt of such deposit and Request for File Release with respect
thereto, the Co-Trustee shall release the related Mortgage File to [CHL] and
shall execute and deliver at [CHL]'s request such instruments of transfer or
assignment as [CHL] has prepared, in each case without recourse, as shall be
necessary to vest in [CHL], or a designee, the Trustee's interest in any
Initial Mortgage Loan released pursuant hereto. If pursuant to the foregoing
provisions [CHL] repurchases an Initial Mortgage Loan that is a MERS Mortgage
Loan, the Master Servicer shall cause MERS to execute and deliver an
assignment of the Mortgage in recordable form to transfer the Mortgage from
MERS to [CHL] and shall cause such Mortgage to be removed from registration on
the MERS(R) System in accordance with MERS' rules and regulations.

            The Co-Trustee shall retain possession and custody of each
Mortgage File in accordance with and subject to the terms and conditions set
forth herein. Each Seller shall promptly deliver to the Co-Trustee, upon the
execution or receipt thereof, the originals of such other documents or
instruments constituting the Mortgage File that come into the possession of
such Seller from time to time.

            It is understood and agreed that the obligation of [CHL] to
substitute for or to purchase any Mortgage Loan that does not meet the
requirements of Section 2.02(a) above shall constitute the sole remedy
respecting such defect available to the Trustee, the Co-Trustee, the Depositor
and any Certificateholder against any Seller.

             It is understood and agreed that the obligation of [CHL] to
substitute for or to purchase, pursuant to Section 2.02(a), any Initial
Mortgage Loan whose Mortgage File contains any document or documents that does
not meet the requirements of clauses (i)-(iv) and (vi) above and which defect
is not corrected or cured by [CHL] within [90] days from the date it was
notified of such defect, shall constitute the sole remedy respecting such
defect available to the Trustee, the Co-Trustee, the Depositor and any
Certificateholder against any Seller.

documents appear regular on their face and relate to such Subsequent Mortgage
Loan.

the Subsequent Transfer Date to the Depositor, the Master Servicer and [CHL]
(on behalf of each Seller) an Interim Certification substantially in the form

of the "Mortgage Loan Schedule" accurately reflects information set forth in
the Mortgage File. On or before the [thirtieth] day after the Subsequent
Transfer Date (or if such [thirtieth] day is not a Business Day, the
succeeding Business Day), the Trustee shall deliver to the Depositor, the
Master Servicer and [CHL] (on behalf of each Seller) a Delay Delivery
Certification with respect to the Subsequent Mortgage Loans substantially in
the form annexed hereto as Exhibit G-3, with any applicable exceptions noted
thereon, together with a Subsequent Certification substantially in the form
annexed hereto as Exhibit G-4. The Trustee shall be under no duty or

certificates or other papers to determine that the same are genuine,
enforceable or appropriate for the represented purpose or that they have

what they purport to be on their face.

            Not later than [180] days after the Subsequent Transfer Date, the
Trustee shall deliver to the Depositor, the Master Servicer, [CHL] (on behalf
of each Seller) and to any Certificateholder that so requests a Final
