                         CONVEYANCE OF THE MORTGAGE LOANS

      Section 2.01 Conveyance of the Mortgage Loans.

      (a) The Depositor, concurrently with the execution and delivery of this
Agreement, does hereby transfer, assign, set over and otherwise convey to the
Trust, without recourse (subject to Sections 2.02 and 2.04) all of its right,
title and interest in and to (i) each Mortgage Loan listed on the Mortgage Loan
Schedule on the Closing Date and the related Mortgage File (including the
related Mortgage Note and Mortgage), including its Cut-off Date Principal
Balance (including all rights of the Depositor pursuant to the Mortgage Loan
Purchase Agreement to purchase Additional Balances resulting from Draws made
pursuant to the related Mortgage Note prior to the termination of this
Agreement) and all related collections in respect of such Mortgage Loan received
after the Cut-off Date (excluding scheduled interest payments due on or prior to
the Cut-off Date); (ii) related property that secured a Mortgage Loan and which
has been acquired by foreclosure or deed in lieu of foreclosure; (iii) its
rights under any related insurance policies maintained in respect of the
Mortgage Loans (including any Insurance Proceeds) provided, however, that
neither the Indenture Trustee nor the Trust assumes any obligation under any
Mortgage Note for the funding of future Draws to the Mortgagor thereunder, and
neither the Indenture Trustee nor the Trust will be obligated or permitted to
fund any such future Draws; and (vi) any and all proceeds of the foregoing
(collectively, the "Conveyed Assets"). Additional Balances shall be included in
the related Principal Balance transferred to the Trust pursuant to this Section
2.01 and therefore will be part of the corpus of the Trust.

       The Seller, the Depositor and the Trust agree to take or cause to be taken
such actions (including without limitation the filing of the UCC-1 financing
statements in the States of

                                       34



 
<Page>


California, in the case of the Seller, and the State of Delaware, in the case of
the Depositor (which shall have been filed on or before the Closing Date)
describing the Cut-off Date Principal Balances and Additional Balances related
to the Mortgage Loans, and naming the Seller as debtor and the Depositor as
secured party, in the case of the Seller, and naming the Depositor as debtor and
the Trust as secured party, in the case of the Depositor, and any amendments to
such UCC-1 financing statements required to reflect a change in the name or
corporate structure of the Seller, the Depositor, or the Trust, as the case may
be, or the filing of any additional financing statement due to the change in the
jurisdiction of formation of the Seller, the Depositor or the Trust, as the case
may be, within 30 days of any event necessitating such filing) as are necessary
to perfect and protect the Depositor's interest in the case of the Seller and
the Trust and the Insurer's interest in the case of the Depositor, in each case
describing Cut-off Date Principal Balance and the Additional Balances related to
the Mortgage Loans, the remainder of the trust estate and the proceeds thereof.
In addition, the Servicer agrees to file continuation statements with respect to
such UCC-1 financing statements as required and as long as this Agreement
remains outstanding with such authorization and information as may be necessary
to make such filing to be provided by the applicable parties.

      In the event any loss is suffered by the Insurer or the Indenture Trustee,
on behalf of the Trust, in respect of any Mortgage Loan, as a result of a
failure by the Seller or the Depositor to file the UCC-1 financing statements
when required to perfect or maintain the perfection of the Indenture Trustee's
security interest hereunder and afford it first priority, the Seller shall, on
the Business Day next preceding the Payment Date in the month following the
Collection Period during which such loss occurred, purchase such Mortgage Loan.
Such purchase shall be accomplished in the same manner as set forth in Section
2.02.

      In addition, on or prior to the Closing Date, the Depositor shall cause
the Insurer to deliver the Policy to the Indenture Trustee, for the benefit of
the Class A Noteholders.

      (b) In exchange for the transfer of the Mortgage Loans on the Closing
Date, the Class B, Class L and Class R Certificates and the Class M1 and Class
M2 Notes shall be issued to or at the direction of the Depositor.

      (c) In consideration of the sale of any Additional Balance from the
Depositor to the Trust on any day, the Trust shall pay or cause to be paid to
the Depositor or its designee an amount equal to the aggregate principal
balances of the related Draws on such day. The Trust shall fund the amount
specified in the preceding sentence in one of the following ways, as applicable:
(i) with respect to any Collection Period preceding the commencement of the
Rapid Amortization Period, (a) on each day during such Collection Period, a cash
payment, to the extent then available from the Floating Allocation Percentage of
Principal Collections on the Mortgage Loans received during such Collection
Period and remaining on deposit in the Collection Account, in an amount equal to
the Aggregate Draw Amount on such day, and (b) on the last day of such
Collection Period, to the extent there exists an Additional Balance Advance
Amount for such Collection Period, an increase in the Class Principal Balance of
the Class L Certificate, equal to such Additional Balance Advance Amount, and
(ii) for any day on and after the first day of the Collection Period in which
the commencement of the Rapid Amortization Period occurs,

                                       35



 
<Page>


and any Collection Period thereafter, an increase in the Class Principal Balance
of the Class L Certificate in an amount equal to the aggregate principal balance
of Additional Balances on such day.

      (d) Prior to the last day of each Collection Period preceding the
commencement of the Rapid Amortization Period, the Holder of the Class L
Certificate shall purchase the Additional Balance Advance Amount for the related
Payment Date, if any, and the Seller shall deliver to the Indenture Trustee and
the Holder of the Class L Certificates two Business Days prior to the following
Servicer Remittance Date an Advance Notice including the aggregate amount of the
expected Additional Balance Advance Amount for that date. Upon receipt of such
notice and in any event no later than two Business Days prior to the following
Payment Date, the Holder of the Class L Certificate shall make an advance to the
Trust in the amount specified in such Advance Notice by depositing such amount
into the Reserve Account. The Indenture Trustee shall cause such amount to be
remitted to the Seller on such following Payment Date. In addition, on and after
the first day of the Collection Period in which the commencement of the Rapid
Amortization Period occurs, the Holder of the Class L Certificate shall purchase
Additional Balances that are transferred to the Trust (as such Additional
Balances are conveyed and in the amounts specified by the Servicer) by
depositing into the Reserve Account the amount of the Draws relating to such
Additional Balances, which amount shall be disbursed by the Indenture Trustee to
the Seller. The Class Principal Balance of the Class L Certificates will be
increased by the amount of any such purchased Additional Balance Advance Amounts
or Additional Balances, as applicable, as described in Section 2.01(c) above.

      (e) (i) In connection with such transfer, assignment, sale and conveyance
by the Depositor will deliver or have delivered to, and deposit with, the
Indenture Trustee (or its designee), on or before the Closing Date, the Mortgage
Loan Schedule in computer readable format.

      (ii) In connection with such transfer, assignment, sale and conveyance by
      the Depositor, the Depositor shall cause the Seller to deliver to and
      deposit with the Indenture Trustee (x) the Mortgage Note in respect of
      each Mortgage Loan and (y) the Related Documents within 90 days following
      the occurrence of the Closing Date. The Mortgage Note and the Related
      Documents shall be in the following form:

                  (A) the original Mortgage Note, endorsed in blank, or a copy
            of such original Mortgage Note with an accompanying Lost Note
            Affidavit;

                  (B) the original Assignment of Mortgage, from the Seller
            either in blank or to "Deutsche Bank National Trust Company, as
            Indenture Trustee for IndyMac Home Equity Mortgage Loan Asset-Backed
            Trust, Series 2006-H3 under the Sale and Servicing Agreement dated
            September 14, 2006," which assignment shall be in form and substance
             acceptable for recording;

                                       36



 
<Page>


                  (C) the original Mortgage, with evidence of recording thereon,
            provided that if the original Mortgage has been delivered for
             recording to the appropriate public recording office of the
            jurisdiction in which the Mortgaged Property is located but has not
            yet been returned to the Seller by such recording office, the Seller
            shall deliver to the Indenture Trustee a certified true copy of such
            original Mortgage so certified by or on behalf of the Seller,
            together with a certificate by or on behalf of the Seller certifying
            that such original Mortgage has been so delivered to such recording
            office; in all such instances, the Seller shall deliver or cause to
            be delivered the original recorded Mortgage to the Indenture Trustee
            promptly upon receipt of the original recorded Mortgage;

                  (D) intervening assignments, if any, with evidence of
            recording thereon, provided that if such intervening assignment has
            been delivered for recording to the appropriate public recording
            office of the jurisdiction in which the Mortgaged Property is
            located but has not yet been returned to the Seller by such
            recording office, the Seller shall deliver to the Indenture Trustee
            a certified true copy of such intervening assignment so certified by
            the Seller, together with a certificate by or on behalf of the
            Seller certifying that such intervening assignment has been so
            delivered to such recording office; in all such instances, the
             Seller shall deliver or cause to be delivered the original
            intervening assignment to the Indenture Trustee promptly upon
            receipt of the original intervening assignment; and

      provided, however, that as to any Mortgage Loan, if as evidenced by an
Opinion of Counsel delivered to and in form and substance satisfactory to the
Indenture Trustee, the Insurer, and the Rating Agencies (x) an optical image or
other representation of the related document specified in clause (d)(ii)(C)
above is enforceable in the relevant jurisdictions to the same extent as the
original of such document and (y) such optical image or other representation
does not impair the ability of an owner of such Mortgage Loan to transfer or
perfect its interest in such Mortgage Loan, such optical image or other
representation may be delivered as required in clause (d)(ii).

      The Seller and the Depositor each hereby confirms to the Indenture Trustee
and the Insurer that it has made the appropriate entries in its general
accounting records, to indicate that such Mortgage Loans have been sold to the
Depositor by the Seller, and sold by the Depositor to the Trust. The Servicer
hereby confirms to the Indenture Trustee and the Insurer that it has clearly and
unambiguously made appropriate entries in its general accounting records
indicating that such Mortgage Loans constitute part of the Trust and are
serviced by it on behalf of the Trust in accordance with the terms hereof.

      The Seller shall deliver to the Indenture Trustee, as initial custodian
and bailee for the benefit of the Trust, the documents and instruments listed
above in this clause (e).

      The Assignments of Mortgage will be held by the Indenture Trustee, subject
to the conditions provided below in clause (f).

                                       37



 
<Page>


      (f) It is the express intent of the parties hereto that the conveyance of
the Mortgage Loans and the other property described above by the Depositor to
the Trust, as provided in this Agreement be, and be construed as, a sale of all
of the Depositor's right, title and interest in the Mortgage Loans and the other
property described above by the Depositor to the Trust. It is, further, not the
intention of the parties that such conveyance be deemed a pledge of the Mortgage
Loans and the other property described above by the Depositor to the Trust to
secure a debt or other obligation of the Depositor. However, in the event that,
notwithstanding the intent of the parties, the Mortgage Loans and the other
property described above are held to be property of the Depositor, or if for any
reason this Agreement is held or deemed to create a security interest in the
Mortgage Loans and the other property described above, then, (x) this Agreement
shall also be deemed to be a security agreement within the meaning of Articles 8
and 9 of the UCC; and (y) the Depositor hereby grants to the Trust a security
interest in and to all of the Depositor's right, title, and interest, whether
now owned or hereafter acquired, in and to the Conveyed Assets.

      The possession by the Indenture Trustee or its designee, of Mortgage
Files, including the Mortgage Notes and the Mortgages and such other goods,
letters of credit, advices of credit, instruments, money, documents, chattel
paper (tangible and electronic) or certificated securities in accordance with
the terms of this Agreement shall be deemed to be "possession by the secured
party," or possession by a purchaser or a person designated by him or her, for
purposes of perfecting the security interest pursuant to the UCC (including,
without limitation, Sections 9-313, 8-313 or 8-321 thereof); and notifications
to persons holding such property, and acknowledgments, receipts or confirmations
from persons holding such property, shall be deemed to be notifications to, or
acknowledgments, receipts or confirmations from, securities intermediaries,
bailees or agents of, or persons holding for, the Indenture Trustee or its
designee, as applicable, for the purpose of perfecting such security interest
under applicable law. The Seller, the Servicer and the Depositor shall, to the
extent consistent with this Agreement, take such actions as may be necessary to
ensure that, if this Agreement were deemed to create a security interest in the
Mortgage Loans and the proceeds thereof, such security interest would be deemed
to be a perfected security interest of first priority under applicable law and
will be maintained as such throughout the term of the Agreement. In connection
herewith, the Trust shall have all of the rights and remedies of a secured party
and creditor under the UCC. Notwithstanding the foregoing, in taking such
actions as may be necessary to ensure that, if this Agreement were deemed to
create a security interest in the Mortgage Loans and the proceeds thereof, such
security interest would be deemed to be a perfected security interest of first
priority under applicable law, and maintaining such throughout the term of this
Agreement.

      (g) On the Closing Date, the Indenture Trustee, will, for the benefit of
Noteholders and the Insurer, review each Mortgage Loan and the related Mortgage
File to ascertain that all required documents set forth in Section
2.01(e)(ii)(A) have been received and shall deliver to the Depositor, the
Servicer, and the Insurer an initial certification (the "Initial Certification")
in the form annexed hereto as Exhibit J to the effect that as to each Mortgage
Loan listed in the Mortgage Loan Schedule (other than any Mortgage Loan prepaid
in full or any specifically identified in such certification as not covered by
such certification), all of the applicable documents specified in Section
2.01(e)(ii)(A) are in its possession. Within 90 days after the Closing Date, the
Indenture Trustee, will, for the benefit of Noteholders and the Insurer, review

                                       38



 
<Page>


each Mortgage File to ascertain that all required documents set forth in Section
2.01(e)(ii) have been received and appear on their face to contain the requisite
signatures by or on behalf of the respective parties thereto, and shall deliver
to the Depositor, the Servicer and the Insurer an interim certification (the
"Interim Certification") in the form annexed hereto as Exhibit K to the effect
that, as to each Mortgage Loan listed in the Mortgage Loan Schedule (other than
any Mortgage Loan prepaid in full or any specifically identified in such
certification as not covered by such certification), (i) all of the applicable
documents specified in Section 2.01(e) are in its possession and (ii) such
documents have been reviewed by it and appear to relate to such Mortgage Loan.
The Indenture Trustee shall determine whether such documents are executed and
endorsed, but shall be under no duty or obligation to inspect, review or examine
any such documents, instruments, certificates or other papers to determine that
the same are valid, binding, legally effective, properly endorsed, genuine,
enforceable or appropriate for the represented purpose or that they have
actually been recorded or are in recordable form or that they are other than
what they purport to be on their face. The Indenture Trustee shall not have any
responsibility for verifying the genuineness or the legal effectiveness of or
authority for any signatures of or on behalf of any party or endorser.

      (h) If in the course of the review described in paragraph (e) above the
Indenture Trustee discovers any document or documents constituting a part of a
Mortgage File that is missing, does not appear regular on its face (i.e., is
mutilated, damaged, defaced, torn or otherwise physically altered) or appears to
be unrelated to the Mortgage Loans identified in the Mortgage Loan Schedule, as
applicable (each, a "Material Defect"), the Indenture Trustee, upon discovering
such Material Defect shall promptly identify the Mortgage Loan to which such
Material Defect relates in the Interim Certification delivered to each of the
Depositor and the Servicer and give notice thereof to the Seller.

      (i) Within 180 days following the Closing Date, the Indenture Trustee
shall deliver to the Depositor, the Servicer and the Insurer a final
certification (the "Final Certification") substantially in the form attached as
Exhibit L evidencing the completeness of the Mortgage Files in its possession or
control, with any exceptions noted thereto.

      (j) Nothing in this Agreement shall be construed to constitute an
assumption by the Trust Estate, the Indenture Trustee, the Administrator, any
Custodian or the Noteholders of any unsatisfied duty, claim or other liability
on any Mortgage Loan or to any Mortgagor. The Indenture Trustee shall have no
responsibility for reviewing any Mortgage File except as expressly provided in
this Section 2.01. In reviewing any Mortgage File pursuant to this Section, the
Indenture Trustee shall have no responsibility for determining whether any
document is valid and binding, whether the text of any assignment or endorsement
is in proper or recordable form (except, if not assigned to the Indenture
Trustee or endorsed in blank, to determine if the Indenture Trustee is the
assignee or endorsee), whether any document has been recorded in accordance with
the requirements of any applicable jurisdiction, or whether a blanket assignment
is permitted in any applicable jurisdiction, whether any Person executing any
document is authorized to do so or whether any signature thereon is genuine, but
shall only be required to determine whether a document has been executed, that
it appears regular on its face and is

                                       39



 
<Page>


related to such Mortgage Loan, and, upon the return of such document from the
county recorder's office in accordance with this section, that it purports to be
recorded.

      (k) The Indenture Trustee shall have the right to appoint a custodian to
act on its behalf with respect to its obligations under Section 2.01(g) through
(i).

      (l) (i) Upon the occurrence of a Recordation Event, the Indenture Trustee
shall within 90 days of such Recordation Event submit, at the expense of the
Seller, to the appropriate recording offices Assignments of Mortgage to the
Indenture Trustee on behalf of the Trust, which may be blanket assignments if
permitted by applicable law, for the Mortgage Loans. In lieu of recording any
such Assignments of Mortgage, the Servicer may provide to the Indenture Trustee
and the Insurer an Opinion of Counsel in a form reasonably acceptable to the
Owner Trustee, Indenture Trustee and the Insurer, to the effect that recordation
of an Assignment of Mortgage in the state where the related Mortgaged Property
is located is not necessary to protect the interests of the Owner Trustee, the
Indenture Trustee or the Securityholders in the related Mortgage. In the event
that any such Assignment of Mortgage is lost or returned unrecorded because of a
defect therein, the Indenture Trustee shall promptly prepare, at the expense of
the Seller, a substitute Assignment of Mortgage or cure such defect, as the case
may be, and thereafter the Indenture Trustee shall, at the expense of the
Seller, submit each such Assignment of Mortgage for recording.

      (ii) With respect to each MERS Mortgage Loan, the Servicer shall, at the
expense of the Depositor, take such actions as are necessary to cause the
Indenture Trustee to be clearly identified as the owner of each such Mortgage
