<PAGE>

requisite corporate or other action to execute and deliver this Agreement and
his or its Securities, to purchase his or its Securities and to carry out and

Agreement and his or its Securities each constitute the legal, valid and binding
obligation of the Purchaser, enforceable in accordance with its terms, except

investment intent as expressed herein. Purchaser has, in connection with his or
its decision to purchase his or its Securities, relied solely upon the SEC
Documents and the representations and warranties of the Company contained

                                SCHEDULE OF EXCEPTIONS

The following are exceptions to the representations and warranties of Imaging
Technologies Corporation (the "Company") set forth in that certain Subordinated
Note Purchase Agreement dated as of September __, 1998 (the "Agreement"), with
reference to the Section designations of the Agreement. The references to
specific Sections are not meant and should not be construed as limiting the
noted exceptions to a particular Section. Although the Company has used its
reasonable best efforts to cross-reference the exceptions to all applicable
representations and warranties, no assurance can be given that all necessary
cross-references have been identified and any exception noted below is therefore
deemed disclosed for purposes of all relevant Sections whether or not
cross-referenced. Capitalized terms not otherwise defined in this Schedule of
Exceptions have the meaning given them in the Agreement. Nothing herein
constitutes an admission of any liability or obligation of the Company nor an
admission against the Company's interest. The inclusion of any agreement or
other matter herein or any exhibit hereto should not be interpreted as
indicating that the Company has determined that such an agreement or other
matter is necessarily material to the Company.


SECTION NUMBER           EXCEPTIONS

Section 3.2         CORPORATE POWER; AUTHORIZATION.

                    1. Pursuant to the terms of that certain Promissory Note
                    between McMican Corporation dba New Media Memory and Bank of
                    Yorba Linda (the "Lender"), dated June 17, 1997, that
                    certain Commercial Security Agreement between McMican
                    Corporation dba New Media Memory and Lender, dated June 17,
                    1997, that certain Loan Agreement between McMican
                    Corporation dba New Media Memory and Lender, dated October
                    20, 1997 and that certain Change in Terms Agreement between
                    McMican Corporation dba New Media Memory and Lender, dated
                    May 17, 1998 (collectively, the "Yorba Linda Line of
                    Credit"), the Company has outstanding approximately $390,000
                    in principal amount of indebtedness. The Yorba Linda Line of
                    Credit matured on August 15, 1998 and requires that the
                    Company obtain Lender's written consent prior to issuing the
                    Subordinated Notes. The Company is currently in the process
                    of obtaining additional credit from Imperial Bank to pay off
                    all amounts owed to the Lender under the Yorba Linda Line of
                    Credit. As a result, the Company has not obtained Lender's
                    written consent to issuing the Subordinated Notes.


<PAGE>

                    2. Pursuant to its agreements with Imperial Bank, the
                    Company is required to obtain the written consent of
                    Imperial Bank prior to the sale and issuance of Notes and
                    Warrants pursuant to the Agreement, and prior to the sale of
                    certain other notes and warrants and certain shares of the
                    Company's common stock being sold in connection herewith.
                    The Company has not obtained Imperial Bank's written
                    consent.

Section 3.3         ISSUANCE AND DELIVERY OF SECURITIES.

                    The Company has agreed to issue the Warrants to the
                    Purchasers pursuant to the Agreement, and certain warrants
                    (the "Other Warrants") to other investors (the "Other
                    Investors") under separate purchase agreements. In addition,
                    pursuant to the Agreement, the Company has agreed to issue
                    and sell to the Purchasers the Convertible Notes, which are
                    convertible at the option of the Purchasers into shares of
                    the Company's Common Stock. Under the terms of Section 4(g)
                    of that certain Securities Purchase Agreement dated August
                    21, 1997, between the Company and the holders of the
                    outstanding shares of the Company's Series C Preferred Stock
                    (the "Series C Holders"), the Company is required to offer
                    any equity or convertible debt securities it intends to
                    issue to the Series C Holders prior to offering the
                    securities to any third party. The Company has not offered
                    the Warrants, the Convertible Notes or the Other Warrants to
                    the Series C Holders, who will retain their right of first
                    offer until the closing of the Company's settlement with the
                    Series C Holders, which will not occur until after the
                    Company has issued the Warrants and the Convertible Notes to
                    the Purchasers and the Other Warrants to the Other
                    Investors.

Section 3.4         GOVERNMENTAL CONSENTS.

                    In connection with the issuance of the Subordinated Notes
                    and the Warrants under this Agreement, the Company was
                    required to obtain and has obtained a qualification by
                    permit from the Commissioner of Corporations of the State of
                    California to exempt the payment of the interest under the
                    Subordinated Notes from the usury laws of the State of
                    California.

Section 3.7         NO MATERIAL ADVERSE CHANGE.

                    1. On June 19, 1998, the Company delivered notice to the
                    Series C Holders of its election to redeem for cash all
                    shares of Series C Preferred Stock tendered for conversion
                    in lieu of converting such shares. Certain disputes have
                    arisen between the Company and the Series C Holders with
                    respect to such notice and the Company's right to redeem all
                    shares of Series C Preferred Stock tendered for conversion
                    in lieu of converting 


<PAGE>

                    such shares. The Series C Holders have asserted that the
                    Company is in default of its obligations to them.

                    2. The Company has recently been informed by Imperial Bank,
                    the Company's primary lender, that the Company is not in
                    compliance with all of the provisions of its loan agreements
                    with Imperial Bank, including without limitation, the
                    provisions regarding certain minimum ratios the Company is
                    required to maintain. The Company's noncompliance with many
                    of these provisions results from the expected one-time
                    charge to earnings that the Company intends to include in
                    its financial statements as of and for the fiscal year ended
                    June 30, 1998, which one-time charge the Company currently
                    anticipates will be as much as approximately $9,000,000.

                    3. On September 3, 1998, the Company issued unsecured
                    promissory notes to certain investors in the aggregate
                    principal amount of $500,000. Pursuant to its agreements
                    with Imperial Bank, the Company was required to obtain
                    Imperial Bank's consent prior to issuing these notes. The
                    Company did not obtain Imperial Bank's consent.

                    4. See the disclosures in Section 3.3 above.

To the Purchasers Listed
on Schedule A to the
Imaging Technologies Corporation
Subordinated Note Purchase Agreement
dated September 17, 1998

Ladies and Gentlemen:

                  We have acted as counsel for Imaging Technologies Corporation,
a Delaware corporation (the "Company"), in connection with the issuance and sale
of its Subordinated Promissory Notes pursuant to the Imaging Technologies
Corporation Subordinated Note Purchase Agreement dated September 17, 1998 (the
"Note Purchase Agreement") among the Company and you. This opinion letter is
being rendered to you pursuant to Section 5.6 of the Note Purchase Agreement in
connection with the Closing of the sale of the Subordinated Promissory Notes.
Capitalized terms not otherwise defined in this opinion letter have the meaning
given them in the Note Purchase Agreement.

                  In connection with the opinions expressed herein we have made
such examination of matters of law and of fact as we considered appropriate or
advisable for purposes hereof. As to matters of fact material to the opinions
expressed herein, we have relied upon the representations and warranties as to
factual matters contained in and made by the Company pursuant to the Note
Purchase Agreement and upon certificates and statements of government officials
and of officers of the Company. We have also examined originals or copies of

                  As used in this opinion letter, the expression "we are not
aware" or the phrase "to our knowledge", or any similar expression or phrase

information), and after an examination of documents referred to herein and after
inquiries of certain officers of the Company, no facts have been disclosed to us
that have caused us to conclude that the opinions expressed are factually
incorrect; but beyond that we have made no factual investigation for the
purposes of rendering this opinion letter. Specifically, but without limitation,
we have made no inquiries of securities holders or employees of the Company,
other than such officers.

                  This opinion letter relates solely to the laws of the State of
California, the Delaware General Corporation Law and the federal law of the
United States, and we express no opinion with respect to the effect or
application of any other laws. Special rulings of authorities administering such
laws or opinions of other counsel have not been sought or obtained.

                  Based upon our examination of and reliance upon the foregoing
and subject to the limitations, exceptions, qualifications and assumptions set
forth below and except as set forth in the Note Purchase Agreement or the
Schedule of Exceptions thereto, we are of the opinion that as of the date
hereof:

                  1. The Company is a corporation duly incorporated, validly
existing and in good standing under the laws of the State of Delaware, and the
Company has the requisite corporate power and authority to own its properties
and to conduct its business as, to our knowledge, it is presently conducted.

                  2. The Company is qualified to do business as a foreign
corporation in California and is in good standing under the laws of the State of
California.

                  3. The Company has the requisite corporate power and authority
to execute, deliver and perform the Note Purchase Agreement, the Subordinated
Promissory Notes and the Warrants. Each of the foregoing has been duly and
validly authorized by the Company, and duly executed and delivered by an
authorized officer of the Company.

                  4. The Company's execution and delivery of, and its
performance and compliance as of the date hereof with the terms of, the Note
Purchase Agreement, the Subordinated Promissory Notes and the Warrants do not
violate any provision of any federal or California law, rule or regulation
applicable to the Company or any provision of the Company's Certificate of
Incorporation, as amended, or Bylaws, and do not conflict with or constitute a
default under the material provisions of any agreement specifically identified
on Schedule A attached hereto, other than a default under the agreements related
to the Company's loans from Imperial Bank and Bank of Yorba Linda, one or more
of which require the Company to obtain Imperial Bank's and Bank of Yorba Linda's
prior written consent (which consent the Company has not obtained prior
