              REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE PURCHASER

          Each Purchaser hereby, severally and not jointly, represents and
warrants to the Company as of the Closing Date as follows:

          4.1 AUTHORIZATION. Purchaser represents and warrants to the Company
that: (i) Purchaser has all requisite legal and corporate or other power and
capacity and has taken all requisite corporate or other action to execute and
deliver this Agreement, to purchase its Securities and to carry out and perform
all of its obligations under this Agreement; and (ii) this Agreement, the
Subordinated Note and the Warrant each constitute the legal, valid and binding
obligation of the Purchaser, enforceable against it in accordance with its
terms, except (a) as limited by applicable bankruptcy, insolvency,
reorganization, or similar laws relating to or 



                                       3
<PAGE>


affecting the enforcement of creditors' rights generally and (b) as limited by
equitable principles generally.

          4.2 INVESTMENT EXPERIENCE. Purchaser is an "accredited investor" as
defined in Rule 501(a) under the Securities Act. Purchaser is aware of the
Company's business affairs and financial condition and has had access to and has
acquired sufficient information about the Company to reach what it believes is
an informed and knowledgeable decision to purchase its Securities. Purchaser has
such business and financial experience as is required to give it the capacity to
protect its own interests in connection with the purchase of its Securities.

          4.3 INVESTMENT INTENT. Purchaser is purchasing its Securities for its
own account as principal, for investment purposes only, and not with a present
view to, or for, resale, distribution or fractionalization thereof, in whole or
in part, within the meaning of the Securities Act; provided, however, that by
making the representation herein, such Purchaser does not agree to hold any of
the Securities for any minimum or other specific term and reserves the right to
dispose of the Securities at any time in accordance with or pursuant to a
registration statement or an exemption under the Securities Act. Purchaser
understands that its acquisition of its Securities has not been registered under
the Securities Act or registered or qualified under any state securities law in
reliance on specific exemptions therefrom, which exemptions may depend upon,
among other things, the bona fide nature of Purchaser's investment intent as
expressed herein. Purchaser has, in connection with its decision to purchase its
Securities, relied solely upon the SEC Documents and the representations and
warranties of the Company contained herein. Purchaser will not, directly or
indirectly, offer, sell, pledge, transfer or otherwise dispose of (or solicit
any offers to buy, purchase or otherwise acquire or take a pledge of) its
Securities except in compliance with the Securities Act, and the rules and
regulations promulgated thereunder.

          4.4 REGISTRATION OR EXEMPTION REQUIREMENTS. Purchaser further
acknowledges and understands that its Securities may not be resold or otherwise
transferred except in a transaction registered under the Securities Act or
unless an exemption from such registration is available.

          4.5 NO LEGAL, TAX OR INVESTMENT ADVICE. Purchaser understands that
nothing in this Agreement or any other materials presented to Purchaser in
connection with the purchase and sale of its Securities constitutes legal, tax
or investment advice. Purchaser has consulted such legal, tax and investment
advisors as it, in its sole discretion, has deemed necessary or appropriate in
connection with its purchase of its Securities.

          4.6 LEGENDS. To the extent applicable, the Subordinated Note shall be
endorsed with the legend set forth below:

                             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 18, 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.

<S>            <C>
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.

<TABLE>
<S>            <C>
               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 the Subordinated Notes and the 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 "Additional
               Warrants") to other investors under separate purchase agreements.
               In addition, pursuant to a certain subordinated note purchase
               agreement among the Company and American Industries, Inc. and
               Ellison Morgan (collectively, the "Other Investors"), the Company
               has agreed to issue and sell to the Other Investors certain
               promissory notes (the "Convertible Notes") that are convertible
               at the option of the Other Investors into shares of the Company's
               Common Stock and certain warrants (together with the Additional
               Warrants, the "Other Warrants") exercisable for 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, the Convertible Notes and the Other
               Warrants.

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 



                                  SCHEDULE B-2
<PAGE>


               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 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.

                               September 18, 1998


To the Purchasers Listed
on Schedule A to the
Imaging Technologies Corporation
Subordinated Note Purchase Agreement
dated September 18, 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 18, 1998 (the
"Note Purchase Agreement") among the Company and you. This opinion letter is
being rendered to you pursuant to Section 5.5 of the Note Purchase Agreement in
connection with the Closing of the sale of the Subordinated 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
such corporate documents or records of the Company as we have considered
appropriate for the opinions expressed herein. We have assumed for the purposes
of this opinion letter the genuineness of all signatures, the legal capacity of
natural persons, the authenticity of the documents submitted to us as originals,
the conformity to the original documents of all documents submitted to us as
certified, facsimile or photostatic copies, and the authenticity of the
originals of such copies.

                  As used in this opinion letter, the expression "we are not
aware" or the phrase "to our knowledge", or any similar expression or phrase
with respect to our knowledge of matters of fact, means as to matters of fact
that, based on the actual knowledge of individual attorneys within the firm
principally responsible for handling this matter for the Company (and not
including any constructive or imputed notice of any 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
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. The Common Stock issuable upon exercise of the Warrants
to be issued at the Closing has been duly and validly reserved for issuance and,
when and if issued upon such exercise pursuant to the terms of the Warrants,
will be validly issued, fully paid and nonassessable.

                  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 Notes and the Warrants do not violate any
provision of any federal, California or Delaware corporate 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

to entering into the Note Purchase Agreement and consummating the transactions
contemplated thereby).

                  5. The Purchasers' loans to the Company evidenced by the
Subordinated Notes are exempt from the usury laws of the State of California.

                  6. Based in part upon the representations of you in the Note
Purchase Agreement, the offer and sale of the Subordinated Notes and the
Warrants to you pursuant to the terms of the Note Purchase Agreement are exempt
from the registration requirements of Section 5 of the Securities Act of 1933,
as amended, by virtue of Section 4(2) thereof and, under the Securities Act of
1933, as amended, as it presently exists, the issuance of Common Stock to you
upon exercise of the Warrants pursuant to the terms of the Warrants would also
be exempt from such registration requirements.

                  We express no opinion as to the Company's compliance or
noncompliance with applicable federal or state antifraud or antitrust statutes,
laws, rules and regulations.

                  We express no opinion concerning the past, present or future
fair market value of any securities.

                  We assume that all of the information contained in the
applications for qualification by permit filed by the Company on July 17, 1998
and September 15, 1998, under Section 25113 of the California Corporations Code,
including without limitation all of the information contained in any amendments
or supplements to the applications, was accurate, that no information required
to be included in the applications or in any amendments or supplements to the
applications was not so included, and that the qualifications by permit were
therefore properly obtained by the Company.

                  We express no opinion as to the effect of subsequent issuances
of securities of the Company, to the extent that further issuances which may be
integrated with the Closing may include purchasers which do not meet the
definition of "accredited investors" under Rule 501 of Regulation D and to the
extent that notwithstanding its reservation of shares the Company may issue so
many shares of Common Stock (or may issue securities which as a result of
antidilution adjustments reduce the conversion or exercise ratio of any
outstanding derivative securities) that there are not enough remaining
authorized but unissued shares of Common Stock for the exercise of the Warrants.

                  This opinion letter is rendered as of the date first written
above solely for your benefit in connection with the Note Purchase Agreement and
may not be delivered to, quoted or relied upon by any person other than you, or
for any other purpose, without our prior written consent. Our opinion is
expressly limited to the matters set forth above and we render no opinion,
whether by implication or otherwise, as to any other matters relating to the
Company. We assume no obligation to advise you of facts, circumstances,
