                  RE:      IMPERIAL CAPITAL TRUST I
                           ------------------------

Ladies and Gentlemen:

                  We have acted as special Delaware counsel for Imperial
Bancorp, a California corporation (the "Company"), and Imperial Capital Trust I,
a Delaware business trust (the "Trust"), in connection with the matters set
forth herein. At your request, this opinion is being furnished to you.

                  For purposes of giving the opinions hereinafter set forth, our
examination of documents has been limited to the examination of originals or
copies of the following:

                  (a) The Certificate of Trust of the Trust, dated as of April
8, 1997 (the "Certificate"), as filed in the office of the Secretary of State of
the State of Delaware (the "Secretary of State") on April 8, 1997;

                  (b) The Declaration of Trust of the Trust, dated as of April
8, 1997, by and among the Company and the trustees of the Trust named therein;

                  (c) The Amended and Restated Declaration of Trust of the
Trust, dated as of April 23, 1997 (including Annex I and Exhibits A-1 and B-1
thereto) (the "Declaration"), among the Company, as sponsor, the trustees of the
Trust named therein and the holders, from time to time, of undivided beneficial
interests in the assets of the Trust;

                  (d) Amendment No. 1 to the Registration Statement on Form S-4
(the "Registration Statement"), including a preliminary prospectus (the
"Prospectus"), relating to the 9.98% Capital Securities of the Trust
representing undivided beneficial interests in the assets of the Trust (each, a
"Capital Security" and collectively, the "Capital Securities"), as proposed to
be filed by the Company and the Trust with the Securities and Exchange
Commission on or about June 18, 1997; and

                  (e) A Certificate of Good Standing for the Trust dated as of
June 18, 1997, obtained from the Secretary of State.

                  Initially capitalized terms used herein and not otherwise
defined are used as defined in the Declaration.

                  For purposes of this opinion, we have not reviewed any
documents other than the documents listed in paragraphs (a) through (e) above.
In particular, we have not reviewed any document (other than the documents
listed in paragraphs (a) through (e) above) that is referred to in or
incorporated by reference into the documents reviewed by us. We have assumed
that there exists no provision in any document that we have not reviewed that is
inconsistent with the opinions stated herein. We have conducted no independent
factual investigation of our own but rather have relied solely upon the
foregoing documents, the statements and information set forth therein and the
additional matters recited or assumed herein, all of which we have assumed to be
true, complete and accurate in all material respects.

                  With respect to all documents examined by us, we have assumed
(i) the authenticity of all documents submitted to us as authentic originals,
(ii) the conformity with the originals of all documents submitted to us as
copies or forms, and (iii) the genuineness of all signatures.

                  For purposes of this opinion, we have assumed (i) that the
Declaration constitutes the entire agreement among the parties thereto with
respect to the subject matter thereof, including with respect to the creation,
operation and termination of the Trust, and

that the Declaration and the Certificate are in full force and effect and have
not been amended, (ii) except to the extent provided in paragraph 1 below, the
due creation or due organization or due formation, as the case may be, and valid
existence in good standing of each party to the documents examined by us under
the laws of the jurisdiction governing its creation, organization or formation,
(iii) the legal capacity of natural persons who are parties to the documents
examined by us, (iv) that each of the parties to the documents examined by us
has the power and authority to execute and deliver, and to perform its
obligations under, such documents, (v) the due authorization, execution and
delivery by all parties thereto of all documents examined by us, (vi) the
receipt by each Person to whom a Capital Security is to be issued by the Trust
(collectively, the "Capital Security Holders") of a certificate (substantially
in the form attached as Exhibit A-1 to the Declaration) evidencing the Capital
Security and the payment for the Capital Security acquired by it, in accordance
with the Declaration and the Registration Statement, and (vii) that the Capital
Securities are issued and sold to the Capital Security Holders in accordance
with the Declaration and the Registration Statement. We have not participated in
the preparation of the Registration Statement and assume no responsibility for
its contents.

                  This opinion is limited to the laws of the State of Delaware
(excluding the securities laws of the State of Delaware), and we have not
considered and express no opinion on the laws of any other jurisdiction,
including federal laws and rules and regulations relating thereto. Our opinions
are rendered only with respect to Delaware laws and rules, regulations and
orders thereunder which are currently in effect.

                  Based upon the foregoing, and upon our examination of such
questions of law and statutes of the State of Delaware as we have considered
necessary or appropriate, and subject to the assumptions, qualifications,
limitations and exceptions set forth herein, we are of the opinion that:

                  1. The Trust has been duly created and is validly existing in
good standing as a business trust under the Business Trust Act.

                  2. The Capital Securities will represent valid and, subject to
the qualifications set forth in paragraph 3 below, fully paid and nonassessable
undivided beneficial interests in the assets of the Trust.

                  3. The Capital Security Holders, as beneficial owners of the 
Trust, will be entitled to the same limitation of personal liability extended 
to stockholders of private

                  We consent to the filing of this opinion with the Securities
and Exchange Commission as an exhibit to the Registration Statement. In
addition, we hereby consent to the use of our name under the heading "Legal
Matters" in the Prospectus. In giving the foregoing consents, we do not thereby
admit that we come within the category of Persons whose consent is required
under Section 7 of the Securities Act of 1933, as amended, or the rules and
regulations of the Securities and Exchange Commission thereunder. Except as
stated above, without our prior written consent, this opinion may not be
furnished or quoted to, or relied upon by, any other Person for any purpose.



                                            Very truly yours,
