to which certain Certificates were sold (the "Purchased Certificates"), (v) the

     In rendering this opinion letter, as to relevant factual matters we have
examined the documents described above and such other documents as we have
deemed necessary including, where we have deemed appropriate, representations or
certifications of officers of parties thereto or public officials. In rendering
this opinion letter, except for the matters that are specifically addressed in
the opinions expressed below, with your permission we have assumed, and are
relying thereon without independent investigation, (i) the authenticity of all
documents submitted to us as originals or as copies thereof, and the conformity
to the originals of all documents submitted to us as copies, (ii) the necessary
entity formation and continuing existence in the jurisdiction of formation, and
the necessary licensing and qualification in all jurisdictions, of all parties
to all documents, (iii) the necessary authorization, execution, delivery and
enforceability of all documents, and the necessary entity power with respect
thereto, and (iv) that there is not any other agreement that modifies or
supplements the agreements expressed in any document to which this opinion
letter relates and that renders any of the opinions expressed below inconsistent
with such document as so modified or supplemented. In rendering this opinion
letter, except for the matters that are specifically addressed in the opinions
expressed below, we have made no inquiry, have conducted no investigation and
assume no responsibility with respect to (a) the accuracy of and compliance by
the parties thereto with the representations, warranties and covenants as to
factual matters contained in any document or (b) the conformity of the
underlying assets and related documents to the requirements of any agreement to
which this opinion letter relates.

     In rendering this opinion letter, any opinion expressed herein with respect
to the enforceability of any right or obligation is subject to (i) general
principles of equity, including concepts of materiality, reasonableness, good
faith and fair dealing and the possible unavailability of specific performance
and injunctive relief, regardless of whether considered in a proceeding in
equity or at law, (ii) bankruptcy, insolvency, receivership, reorganization,
liquidation, voidable preference, fraudulent conveyance and transfer, moratorium
and other similar laws affecting the rights of creditors or secured parties,
(iii) the effect of certain laws, regulations and judicial and other decisions
upon (a) the availability and enforceability of certain remedies, including the
remedies of specific performance and self-help, and provisions purporting to
waive the obligation of good faith, materiality, fair dealing, diligence,
reasonableness or objection to judicial jurisdiction, venue or forum and (b) the
enforceability of any provision the violation of which would not have any
material adverse effect on the performance by any party of its obligations under
any agreement and (iv) public policy considerations underlying United States
federal securities laws, to the extent that such public policy considerations
limit the enforceability of any provision of any agreement which purports or is
construed to provide indemnification with respect to securities law violations.
However, the







Impac Secured Assets Corp., Series 2003-2                                Page 3.

non-enforceability of any provisions referred to in foregoing clause (iii) will
not, taken as a whole, materially interfere with the practical realization of
the benefits of the rights and remedies included in any such agreement which is
the subject of any opinion expressed below, except for the consequences of any
judicial, administrative, procedural or other delay which may be imposed by,
relate to or arise from applicable laws, equitable principles and
interpretations thereof.

     This opinion letter is based solely upon our review of the documents
referred to herein. We have conducted no independent investigation with respect
to the facts contained in such documents and relied upon in rendering this
opinion letter. We also note that we do not represent any of the parties to the
transactions to which this opinion letter relates or any of their affiliates in
connection with matters other than certain transactions. However, the attorneys
in this firm who are directly involved in the representation of parties to the
transactions to which this opinion letter relates have no actual present
knowledge of the inaccuracy of any fact relied upon in rendering this opinion
letter. In addition, if we indicate herein that any opinion is based on our
knowledge, our opinion is based solely on the actual present knowledge of such
attorneys.

     In rendering this opinion letter, we do not express any opinion concerning
any law other than the laws of the State of New York, and the federal laws of
the United States including without limitation the Securities Act of 1933, as
amended (the "1933 Act"). We do not express any opinion herein with respect to
any matter not specifically addressed in the opinions expressed below, including
without limitation (i) any statute, regulation or provision of law of any
county, municipality or other political subdivision or any agency or
instrumentality thereof or (ii) the securities or tax laws of any jurisdiction.


     Based upon and subject to the foregoing, it is our opinion that:

     1.   Each of the Agreements to which the Seller, the Depositor or IMH is a
          party, assuming the necessary authorization, execution and delivery
          thereof by the parties thereto other than any party as to which we
          opine to that effect herein, is a valid and legally binding agreement
          under the laws of the State of New York, enforceable thereunder in
          accordance with its terms against the Seller, Depositor, Master
          Servicer or IMH, as the case may be.

     2.   The issuance, offer, sale and delivery of the Certificates have been
          duly authorized by the Depositor.

     3.   The Certificates, assuming the necessary execution, authentication and
          delivery thereof and payment therefor in accordance with the
          applicable Agreements, are valid and legally binding obligations under
          the laws of the State of New York, enforceable thereunder in
          accordance with their terms against the Depositor, and are entitled to
          the benefits of the Pooling and Servicing Agreement.

     4.   With respect to each of the Seller, the Depositor and IMH, the
          performance of its obligations under each of the Agreements to which
          it is a party and the consummation of the transactions contemplated
          thereby do not require any consent, approval, authorization or order
          of, filing with or notice to any United States federal or State of New
          York court, agency or other governmental body, except such as may be
          required under the securities laws of any State of the United States
          or such as have been obtained, effected or given.

     5.   With respect to each of the Seller, the Depositor and IMH, the
          performance of its obligations under each of the Agreements to which
          it is a party and the consummation of the transactions contemplated
          thereby will not result in (i) to our knowledge, any breach, violation
          or acceleration of or default under any indenture or other material
          agreement or instrument to which it is a party or by which it is bound
          or (ii) any breach or violation of any United States federal or State
          of New York statute or regulation or, to our knowledge, any order of
          any United States federal or State of New York court, agency or other
          governmental body.

     6.   The Registration Statement has become effective under the 1933 Act. To
          our knowledge, no stop order suspending the effectiveness of the
          Registration Statement has been issued and not withdrawn, and no
          proceedings for that purpose have been instituted or threatened under
          Section 8(d) of the 1933 Act.

     7.   The Registration Statement as of the date of the Prospectus Supplement
          and the date hereof, and the Prospectus as of the date of the
          Prospectus Supplement and the date hereof, other than any financial
          and statistical information, Computational Materials and ABS Term
          Sheets contained or incorporated by reference therein as to which we
          express no opinion herein, complied as to form in all material
          respects with the requirements of the 1933 Act and the applicable
          rules and regulations thereunder.

     8.   To our knowledge, there are no material contracts, indentures or other
          documents of a character required to be described or referred to in
          either the Registration Statement or the Prospectus or to be filed as
          exhibits to the Registration Statement, other than any Computational
          Materials and ABS Term Sheets, as to which we express no opinion
          herein, and those described or referred to therein or filed or
          incorporated by reference as exhibits thereto.

     9.   The statements made in the Prospectus under the heading "Description
          of the Offered Certificates" insofar as such statements purport to
          summarize certain provisions of the Certificates and the Pooling and
          Servicing Agreement, provide a fair summary of such provisions. The
          statements made in the Prospectus, under the headings "Federal Income
          Tax Consequences""Legal Aspects of Mortgage Loans - Applicability of
          Usury Laws," and "--Alternative Mortgage Instruments" and "ERISA
          Considerations," to the extent that they constitute matters of United
          States federal or State of New York law or legal conclusions with
          respect thereto, while not

          purporting to discuss all possible consequences of investment in the
          Certificates, are correct in all material respects with respect to
          those consequences or matters that are discussed therein.

     10.  The Pooling and Servicing Agreement is not required to be qualified
          under the Trust Indenture Act of 1939, as amended. The Trust Fund
          created by the Pooling and Servicing Agreement is not an "investment
          company" or "controlled by" an "investment company" within the meaning
          of the Investment Company Act of 1940, as amended.

     11.  The Certificates (other than the Class M-2 Certificates and the Class
          M-3 Certificates) will be "mortgage related securities" as defined in
          Section 3(a)(41) of the Securities Exchange Act of 1934, as amended,
          so long as each such class is rated in one of the two highest rating
          categories by at least one "nationally recognized statistical rating
          organization" as that term is used in that Section.

hereof with respect to the matters specifically addressed herein, and no other
person or entity is entitled to rely hereon. Copies of this opinion letter may
not be made available, and this opinion letter may not be quoted or referred to

                                                 Very truly yours,
