      For and in consideration of the sum of one dollar ($1.00) and other
valuable consideration the receipt and sufficiency of which are hereby
acknowledged, and of the mutual covenants herein contained, the parties hereto
hereby agree as follows:

      1. The Assignor hereby grants, transfers and assigns to ABFC all of the
Assignor's right, title and interest (but none of its obligations) in, to and
under the Purchase Agreement and the Mortgage Loans delivered under such
agreement; provided, however, the Assignor retained its remedies under the

obligated to perform such obligations, and ABFC hereby grants, transfers and
assigns to the Assignee, all of the Assignor's right, title and interest (but
none of its obligations) in, to and under the Purchase Agreement and the
Mortgage Loans delivered under such agreement.

      2. The Assignor warrants and represents to, and covenants with, ABFC and
the Assignee that:

      a.    The Assignor is the lawful owner of the Mortgage Loans with the full
            right to transfer the Mortgage Loans free from any and all claims
            and encumbrances whatsoever;

      b.    The Assignor has not received notice of, and has no knowledge of,
            any offsets, counterclaims or other defenses available to the Seller
            with respect to the Purchase Agreement or the Mortgage Loans;

      c.    The Assignor has not waived or agreed to any waiver under, or agreed
            to any amendment or other modification of, the Purchase Agreement or
            the Mortgage Loans. The Assignor has no knowledge of, and has not
            received notice of, any waivers under or amendments or other
            modifications of, or assignments of rights or obligations under, the
            Purchase Agreement or the Mortgage Loans; and

      d.    Neither the Assignor nor anyone acting on its behalf has offered,
            transferred, pledged, sold or otherwise disposed of the Mortgage
            Loans, any interest in the Mortgage Loans or any other similar
            security to, or solicited any offer to buy or accept a transfer,
            pledge or other disposition of the Mortgage Loans, any interest in
            the Mortgage Loans or any other similar security from, or otherwise
            approached or negotiated with respect to the Mortgage Loans, any
            interest in the Mortgage Loans or any other similar security with,
            any person in any manner, or made any general solicitation by means
            of general advertising or in any other manner, or taken any other
            action which would constitute a distribution of the Mortgage Loans
            under the Securities Act of 1933, as amended (the "Securities Act"),
            or which would render the disposition of the Mortgage Loans a
            violation of Section 5 of the Securities Act or require registration
            pursuant thereto.

      3. From and after the date hereof, WMC shall (i) note the transfer of the
Mortgage Loans to the Assignee in its books and records, and (ii) recognize the
Assignee as the owner of the Mortgage Loans.

      4. WMC acknowledges that the Assignee shall be authorized to enforce the
terms and conditions of the Purchase Agreement. The Assignee shall be authorized
to enforce directly against WMC any of the obligations of WMC provided for in
the Purchase Agreement.

      5. WMC hereby represents and warrants to each of the other parties hereto
(i) that it has taken no action nor omitted to take any required action the
omission of which would have the effect of impairing any mortgage insurance or
guarantee on the Mortgage Loans and (ii) that any written information with
respect to the Mortgage Loans provided by WMC on or before the date hereof to
the Assignor was true and correct in all material respects as of the dates
provided.

      6. WMC hereby agrees that, in connection with each Mortgage Loan of which
the related Mortgage has been recorded in the name of MERS or its designee, it
shall cooperate, to the extent reasonably requested by the Servicer of the
Mortgage Loans and to the extent reasonably necessary to cause the Assignee, as
trustee of the Trust to be shown as the owner of such Mortgage Loan on the
records of MERS for purposes of the system of recording transfers of beneficial
ownership of mortgages maintained by MERS.

      7. It is expressly understood and agreed by the parties hereto that (i)
this Agreement is executed and delivered by U.S. Bank National Association not
individually or personally but solely as trustee on behalf of the Trust, in the
exercise of the powers and authority conferred and vested in it under the terms
of the Pooling Agreement, and (ii) under no circumstances shall U.S. Bank
National Association be personally liable for the payment of any indebtedness or
expenses of the Trust (including, without limitation, any fees, expenses or
indemnities payable under the Pooling Agreement), or be liable for the breach or
failure of any obligation, representation, warranty or covenant of the Trust
under this Agreement or any other related documents, as to all of which recourse
shall be had solely to the assets of the Trust in accordance with the terms of

            such Early Termination Date; (C) notwithstanding anything to the

            no later than two Business Days prior to the final Distribution Date
            that all requirements of the Optional Termination have been met,
            then Party A shall, no later than one Business Day prior to the
            final Distribution Date, make the calculations contemplated by
            Section 6(e) (as amended herein) and provide to the Securities
            Administrator in writing (which may be done in electronic format)
            the amount payable by either Party B or Party A in respect of the
            related Early Termination Date in connection with this Additional
            Termination Event; provided, however, that the amount payable by
            Party B, if any, in respect of the related Early Termination Date
            shall be the lesser of (x) the amount calculated to be due from
            Party B pursuant to Section 6(e) and (y) the Estimated Swap
            Termination Payment; and (D) notwithstanding anything to the

            Event will be payable one Business Day prior to the final
            Distribution Date.

            "Estimated Swap Termination Payment" means, with respect to an Early
            Termination Date, an amount determined by Party A in good faith and
            in a commercially reasonable manner as the maximum payment that
            could be owed by Party B to Party A in respect of such Early
            Termination Date pursuant to Section 6(e) (as amended herein),
            taking into account then current market conditions.

      (iv)  Upon the occurrence of a Swap Disclosure Event (as defined in Part
            5(cc) below) Party A has not, within the greater of (x) five
            calendar days and (y) three Local Business Days after such Swap
            Disclosure Event, complied with any of the provisions set forth in
            Part 5(cc)(iii) below. For all purposes of this Agreement, Party A

            preserving for Party B the economic equivalent of any payment or
            delivery (whether the underlying obligation was absolute or
            contingent and assuming the satisfaction of each applicable
            condition precedent) under this Agreement in respect of such
            Terminated Transaction or group of Terminated Transactions that
            would, but for the occurrence of the relevant Early Termination
            Date, have been required after that date, and (y) has terms which
            are, in all material respects, no less beneficial for Party B than
            those of this Agreement (save for the exclusion of provisions
            relating to Transactions that are not Terminated Transactions), as
            determined by Party B.

            so long as S&P is currently rating the Certificates and either (i)
            if the Relevant Entity is a Financial Institution, the unsecured,
            unguaranteed and otherwise unsupported long-term senior debt

            all of each Relevant Entity's ratings and no longer rates any
            Relevant Entity (such event, an S&P Ratings Event) or (B) so long as
            Fitch is currently rating the Certificates and either (i) the
            unsecured, unguaranteed and otherwise unsupported long-term senior
            debt obligations of each Relevant Entity are rated below "BBB-" by

            efforts to, as soon as reasonably practicable and at its own
            expense: (A) furnish an Eligible Guarantee of Party A's obligations
            under this Agreement from a guarantor that satisfies the definition
            of Hedge Counterparty Ratings Requirement or (B) effect a Permitted

            oral) of the other party as investment advice or as a recommendation
            to enter into that Transaction; it being understood that information
            and explanations related to the terms and conditions of a

            plan or assets deemed to be assets of any such plan in connection
            with any Transaction under this Agreement or (2) any pension plan or
            employee benefits plan subject to the Employee Retirement Income

            Internal Revenue Code of 1986, as amended (the "Code"), or any
            person who is acting on behalf of such a plan, or using assets of

            not result in a prohibited transaction under ERISA or Section 4975
            of the Code.

(d)   Section 4 is hereby amended by adding the following new agreement:

      Actions Affecting Representations. Party B agrees not to take any action
      during the term of this Agreement or any Transaction hereunder that
      renders or could render any of the representations and warranties in this
      Agreement untrue, incorrect, or incomplete, and, if any event or condition
      occurs that renders or could render any such representation untrue,
      incorrect, or incomplete, Party B will immediately give written notice
      thereof to Party A, upon obtaining actual knowledge of such event or
      condition.

(e)   Transfer.

      Section 7 of this Agreement is hereby amended to read in its entirety as
      follows:

      "Neither Party A nor Party B is permitted to assign, novate or transfer
      (whether by way of security or otherwise) as a whole or in part any of its
      rights, obligations or interests under this Agreement or any Transaction
      unless (x) the prior written consent of the other party is obtained and
      (y) the Rating Agency Condition has been satisfied with respect to S&P and
      Fitch; provided, however, that Party A may make, without the consent of
      Party B, a Permitted Transfer of this Agreement (a) pursuant to a
      consolidation or amalgamation with, or merger with or into, or transfer of
      substantially all of its assets to, another entity, (b) pursuant to
      Section 6(b)(ii), (c) at any time at which a Collateralization Event has
      occurred and is continuing, or (d) to any office or branch of Party A on
      at least five Business Days' prior written notice to Party B. Any
      purported transfer that is not in compliance with this Section will be
      void.

      In addition, Party A may transfer this Agreement without the prior written
      consent of the Securities Administrator on behalf of Party B but with
      prior written notice to S&P, Fitch and the Securities Administrator, to an
      Affiliate of Party A that satisfies the Hedge Counterparty Rating
      Requirements or that has furnished a guarantee, subject to Rating Agency
      Condition in relation to S&P, Fitch, of the obligations under this
      Agreement from a guarantor that satisfies the Hedge Counterparty Ratings
      Requirements and provided that such transfer complies with the conditions
      set out in paragraphs (A) to (G) in the definition of Permitted Transfer
      below.

      Permitted Transfer means a transfer by novation by Party A to a transferee
      (the "Transferee") of Party A's rights, liabilities, duties and
      obligations under this Agreement, with respect to which transfer each of
      the following conditions is satisfied: (A) the Transferee is an Eligible
      Replacement; (B) Party A and the Transferee are both "dealers in notional
      principal contracts" within the meaning of Treasury regulations section
      1.1001-4; (C) as of the date of such transfer the Transferee will not be
      required to withhold or deduct on account of a Tax from any payments under
      this Agreement unless the Transferee will be required to make payments of
      additional amounts pursuant to Section 2(d)(i)(4) of this Agreement in
      respect of such Tax; (D) a Termination Event or Event of Default does not
      occur under this Agreement as a result of such transfer; (E) the
      Transferee contracts with Party B pursuant to a written instrument (the
      "Transfer Agreement") (a) (i) on terms which are effective to transfer to
      the Transferee all, but not less than all, of Party A's rights,
      liabilities, duties and obligations under the Agreement and all relevant
      Transactions, which terms are identical to the terms of this Agreement,
      other than party names, dates relevant to the effective date of such
      transfer, tax representations (provided that the representations in Part
      2(a) and Part 5(t) are not modified) and any other representations
      regarding the status of the substitute counterparty, notice information
      and account details, and (ii) each Rating Agency has been given prior
      written notice of such transfer, or (b) (i) on terms that (x) have the
      effect of preserving for Party B the economic equivalent of all payment
      and delivery obligations (whether absolute or contingent and assuming the
      satisfaction of each applicable condition precedent) under this Agreement
      immediately before such transfer and (y) are, in all material respects, no
      less beneficial for Party B than the terms of this Agreement immediately
      before such transfer, as determined by Party B, and (ii) the Rating Agency
      Condition has been satisfied with respect to each Rating Agency; (F) Party
      A will be responsible for any costs or expenses incurred in connection
      with such transfer (including any replacement cost of entering into a
      replacement transaction); and (G) such transfer otherwise complies with
      the terms of the PSA.

      Party B will at Party A's written request and at Party A's expense execute
      such documentation as is reasonably deemed necessary by Party A for the
      effectuation of any Permitted Transfer under this Section 7."

(f)   Proceedings. No Relevant Entity shall institute against, or cause any
      other person to institute against, or join any other person in instituting
      against Party B or the Trust any bankruptcy, reorganization, arrangement,
      insolvency or liquidation proceedings, or other proceedings under any
      federal or state bankruptcy, dissolution or similar law, for a period of
      one year and one day, or if longer the applicable preference period then
      in effect, following payment in full of the Certificates. Nothing shall
      preclude, or be deemed to stop, a Relevant Entity (i) from taking any
      action prior to the expiration of the aforementioned one year and one day
      period, or if longer the applicable preference period then in effect, in
      (A) any case or proceeding voluntarily filed or commenced by Party B or
      (B) any involuntary insolvency proceeding filed or commenced by a Person
      other than a Relevant Entity, (ii) from commencing against Party B or any
      of the Collateral any legal action which is not a bankruptcy,
      reorganization, arrangement, insolvency, moratorium, liquidation or
      similar proceeding, or (iii) from taking any action (not otherwise
      mentioned in this paragraph) which will prevent an impairment of any right
      afforded to it under the PSA as a third party beneficiary. This provision
      shall survive termination of this Agreement.

(g)   Change of Account. Section 2(b) of this Agreement is hereby amended by the
      addition of the following after the word "delivery" in the first line
      thereof:-

      "to another account in the same legal and tax jurisdiction as the original
      account"

(h)   Amendment to PSA. Party B will provide prior written notice to Party A of
      any proposed amendment or modification to the PSA and Party B will obtain
      the prior written consent of Party A (such consent not to be unreasonably
      withheld) to any such amendment or modification where such consent is
      required under the terms of the PSA.

(i)   No Set-off. Except as expressly provided for in Section 2(c) or Section
      6(e) hereof and notwithstanding any other provision of this Agreement or
      any other existing or future agreement, each party irrevocably waives any
      and all rights it may have to set off, net, recoup or otherwise withhold
      or suspend or condition payment or performance of any obligation between
      it and the other party hereunder against any obligation between it and the
      other party under any other agreements. Section 6(e) shall be amended by
      deleting the following sentence: "The amount, if any, payable in respect
      of an Early Termination Date and determined pursuant to this Section will
      be subject to any Set-off.".

(j)   Notice of Certain Events or Circumstances. Each party agrees, upon
      learning of the occurrence or existence of any event or condition that
      constitutes (or that with the giving of notice or passage of time or both
      would constitute) an Event of Default or Termination Event with respect to
      such party, promptly to give the other party notice of such event or
      condition (or, in lieu of giving notice of such event or condition in the
      case of an event or condition that with the giving of notice or passage of
      time or both would constitute an Event of Default or Termination Event
      with respect to the party, to cause such event or condition to cease to
      exist before becoming an Event of Default or Termination Event); provided
      that failure to provide notice of such event or condition pursuant to this
      Part 5(j) shall not constitute an Event of Default or a Termination Event.

(k)   Regarding Party A. Party B acknowledges and agrees that Party A has had
      and will have no involvement in and, accordingly Party A accepts no
      responsibility for: (i) the establishment, structure, or choice of assets
      of Party B; (ii) the selection of any person performing services for or
      acting on behalf of Party B; (iii) the selection of Party A as the
      counterparty; (iv) the terms of the Certificates; (v) the preparation of
      or passing on the disclosure and other information contained in any
      offering circular for the Certificates, the PSA, or any other agreements
      or documents used by Party B or any other party in connection with the
      marketing and sale of the Certificates (other than information provided in
      writing by Party A for purposes of the disclosure document relating to the
      Certificates); (vi) the ongoing operations and administration of Party B,
      including the furnishing of any information to Party B which is not
      specifically required under this Agreement; or (vii) any other aspect of
      Party B's existence.

(l)   Rating Agency Approval of Amendment. In addition to the requirements of
      Section 9, this Agreement will not be amended unless Party B shall have
      obtained satisfaction of the Rating Agency Condition with respect to each
      Rating Agency.

(m)   Jurisdiction. Section 13(b) is hereby amended by: (i) deleting in the
      second line of subparagraph (i) thereof the word "non-": and (ii) deleting
      the final paragraph thereof.

(n)   Limited Recourse. The liability of Party B in relation to this Agreement
      and any Confirmation hereunder is limited in recourse to assets of Party B
      and payments of interest proceeds and principal proceeds thereon applied
      in accordance with the terms of the PSA. Upon application of all of the
      assets of Party B (and proceeds thereon) in accordance with the PSA, Party
      A shall not be entitled to take any further steps against Party B to
      recover any sums due but still unpaid hereunder or thereunder, all claims
      in respect of which shall be extinguished. It is understood that the
      foregoing provisions shall not (i) prevent recourse against Party B for
      the sums due or to become due under any security, instrument or agreement
      which is part of Party B (subject to the priority of payments set forth in
      the PSA) or (ii) constitute a waiver, release or discharge of any
      obligation of Party B arising under this Agreement until the proceeds of
      Party B's assets have been applied in accordance with the PSA.

(o)   Waiver of Jury Trial. Each party waives, to the fullest extent permitted
      by applicable law, any right it may have to a trial by jury in respect of
      any suit, action or proceeding relating to this Agreement or any Credit
      Support Document. Each party certifies (i) that no representative, agent
      or attorney of the other party or any Credit Support Provider has
      represented, expressly or otherwise, that such other party would not, in
      the event of such a suit, action or proceeding, seek to enforce the
      foregoing waiver and (ii) acknowledges that it and the other party have
      been induced to enter into this Agreement and provide for any Credit
      Support Document, as applicable, by, among other things, the mutual
      waivers and certifications in this Section.

(q)   Consent to Recording. Each party (i) consents to the recording of the
      telephone conversations of trading and marketing personnel of the parties
      and their Affiliates in connection with this Agreement or any potential
      transaction and (ii) if applicable, agrees to obtain any necessary consent
      of, and give notice of such recording to, such personnel of it and its
      Affiliates.

(r)   Severability. If any term, provision, covenant, or condition of this
      Agreement, or the application thereof to any party or circumstance, shall
      be held to be illegal, invalid or unenforceable (in whole or in part) for
      any reason, the remaining terms, provisions, covenants and conditions
      hereof shall continue in full force and effect as if this Agreement had
      been executed with the illegal, invalid or unenforceable portion
      eliminated, so long as this Agreement as so modified continues to express,
      without material change, the original intentions of the parties as to the
      subject matter of this Agreement and the deletion of such portion of this
      Agreement will not substantially impair the respective benefits or
      expectations of the parties to this Agreement.

(s)   Escrow Payments. If (whether by reason of the time difference between the
      cities in which payments or deliveries are to be made or otherwise) it is
      not possible for simultaneous payments or deliveries to be made on any
      date on which both parties are required to make payments or deliveries
      hereunder, either party may at its option and in its sole discretion
      notify the other party (Section 2(b) of this Agreement notwithstanding)
      that payments or deliveries on that date are to be made in escrow (such
      party being the "Appointing Party"). In this case, deposit of the payment
      or delivery due earlier on that date will be made by 2:00 pm (local time
      at the place for the earlier payment or delivery) on that date with an
      escrow agent selected by the Appointing Party, accompanied by irrevocable
      payment or delivery instructions (i) to release the deposited payment or
      delivery to the intended recipient upon receipt by the escrow agent of the
      required deposit of the corresponding payment or delivery from the other
      party on the same date accompanied by irrevocable payment or delivery
      instructions to the same effect, or (ii) if the required deposit of the
      corresponding payment or delivery is not made on that same date, to return
      the payment or delivery deposited to the party that paid or delivered it
      into escrow. The Appointing Party will pay all costs of the escrow
      arrangements. The Appointing Party will bear the risk of any failure of
      the entity it nominates to be its escrow agent to fully and promptly
      perform the obligations of such escrow agent as contemplated in this Part
      5(s) Any amounts payable or deliveries to be made under this Agreement by
      the Appointing Party which are not received by the other party hereto on
      the due date will remain due and payable or to be made by the Appointing
      Party as of such date (assuming timely payment or delivery on the due date
      of amounts payable or deliveries to be made by the other party hereto).
      Any amounts or deliveries due from the other party, which have been paid
      or delivered to the escrow agent in accordance with this Part 5(s) (and
      any instructions in connection therewith given to the other party by the
      Appointing Party) shall be treated as having been paid or delivered by
      such other party and received by the Appointing Party as of the date on
      which they were paid or delivered to the Appointing Party's escrow agent.
      The Appointing Party shall cause the escrow arrangements to provide that
      the other party shall be entitled to interest on any payment due to be
      deposited first for each day in the period of its deposit at the rate
      offered by the escrow agent for that day for overnight deposits in the
      relevant currency in the office where it holds that deposited payment (at
      11:00 a.m. local time on that day) if that payment is not released by to
      the other party 5:00 p.m. local time on the date it is deposited for any
      reason other than the intended recipient's failure to make the escrow
      deposit it is required to make under this paragraph in a timely fashion.

(t)   Tax. Notwithstanding the definition of "Indemnifiable Tax" in Section 14
      of this Agreement, in relation to payments by Party A, any Tax shall be an
      Indemnifiable Tax and, in relation to payments by Party B, no Tax shall be
      an Indemnifiable Tax. Section 2(d)(ii) shall not apply to Party B as Y.

(u)   [Reserved]

(v)   Rating Agency Notifications. Notwithstanding any other provision of this
      Agreement, this Agreement shall not be amended, no Early Termination Date
      shall be effectively designated by Party B, and no transfer of any rights
      or obligations under this Agreement shall be made (other than a transfer
      of all of Party A's rights and obligations with respect to this Agreement
      in accordance with Part 5(e) above) unless each Rating Agency has been
      given prior written notice of such amendment, designation or transfer.

(w)   Applicable Rating Agency. Rating triggers and other Rating Agency-related
      provisions herein apply only for so long as that particular Rating Agency
      is rating the securities to which this Transaction applies.

(x)   Timing of Payments by Party B upon Early Termination. Notwithstanding
      anything to the contrary in Section 6(d)(ii), to the extent that all or a
      portion (in either case, the "Unfunded Amount") of any amount that is
      calculated as being due in respect of any Early Termination Date under
      Section 6(e) from Party B to Party A will be paid by Party B from amounts
      other than any upfront payment paid to Party B by any party that has
      entered into a Replacement Transaction with Party B, then such Unfunded
      Amount, together with Interest thereon, shall be due on the Business Day
      prior to the next subsequent Distribution Date following the date on which
      the payment would have been payable as determined in accordance with
      Section 6(d)(ii), and on the Business Day prior to any subsequent
      Distribution Dates until paid in full (or if such Early Termination Date
      is the final Distribution Date, on such final Distribution Date);
      provided, however, that if the date on which the payment would have been
      payable as determined in accordance with Section 6(d)(ii) is a
      Distribution Date, such payment will be payable on such Distribution Date.

(y)   Safe Harbors. Each party to this Agreement acknowledges that:

      (i) This Agreement, including any Credit Support Document, is a "master
      netting agreement" as defined in the U.S. Bankruptcy Code, as amended (the

      Item 1115 of Regulation AB that are applicable to Party A as determined by
      the Depositor in its sole discretion, obtain a guaranty of the Party A's
      obligations under this Agreement from an affiliate of the Party A that is
      able to comply with the financial information disclosure requirements of
      Item 1115 of Regulation AB, such that disclosure provided in respect of

                  securities quoted as at the close of business on such date by

                  available; multiplied by the applicable S&P Valuation
                  Percentage or Fitch Valuation Percentage, as the case may be;
