                                [NAC LETTERHEAD]

                                                              April  25, 2001
Mr. Raymond A. Varcho
12125 West Shiloh Drive
Chesterland, Ohio  44026

                           RE:   SEPARATION FROM NAC
                                 -------------------

Dear Mr. Varcho:

         This letter confirms our agreement with respect to your separation from
National Auto Credit, Inc. and its subsidiaries and affiliates (collectively,
except where the context requires otherwise, "NAC" or the "Company") and the
terms and conditions thereof.

1.   At the close of business on the "Separation Date" (as defined below), you
     will have no further job responsibilities with the Company. The Separation
     Date shall be your last day of employment (i.e., the last day on which you
     are expected to report to work and carry out assigned tasks). Effective at
     the close of business on the Separation Date, you resign as an employee,
     officer and director of NAC and each of NAC's subsidiaries and affiliates.
     You agree that NAC has no obligation, contractual or otherwise, to rehire,
     reemploy or recall you in the future.

2.   The Separation Date shall be the earlier of (A) June 30, 2001 or (B) the
     date specified by you on fourteen (14) days' prior written notice, which
     date shall not be earlier than May 2, 2001. The parties, by mutual
     agreement, may extend the Separation Date beyond June 30, 2001, in which
     event the term "Separation Date" shall mean the date agreed as the end of
     such extension period.

3.   You acknowledge that this Agreement shall supersede any and all contracts
     of employment or other agreements or arrangements with respect to
     employment you have or had with the Company, and such other contracts,
     agreements and arrangements shall hereafter be of no further force or
     effect.

4.            A. Through and including the Separation Date, you shall continue
     to receive not less than your regular salary at the rate now in effect
     (i.e., $200,000 per annum), subject to normal payroll deductions (your "Net
     Salary"), along with all benefits to which you are currently entitled and
     your business expense reimbursement in accordance with the Company's
     current policies.

              B. In consideration for your performance of the covenants set
     forth in this Agreement, your execution of the general release (in the form
     annexed hereto as EXHIBIT A, the "Original Release") and your execution on
     the Separation Date of an additional general release (also in the form
     annexed hereto as EXHIBIT A, except dated the Separation Date), which
     additional general release, when effective, shall supplement but not
     supersede the Original Release (the "Bringdown Release"; as used herein,
     the term "General Release" shall mean the Original Release until the
     Bringdown Release has become effective and thereafter shall mean both the
     Original Release and the Bringdown Release), you shall be entitled to the
     following:

              (i)   Continuation of the payment of your Net Salary for six (6)
                    months following the Separation Date (the "Payment Period"),
                    such amounts to be paid on such dates as salary payments
                    would otherwise have been made if your employment with the
                    Company had not terminated.

              (ii)  The Chief Executive Officer of NAC has determined that NAC
                    has substantially succeeded in winding up its operations in
                    the Cleveland, Ohio area on or before March 1, 2001 and,
                    therefore, you have earned a cash bonus, payable 5 business
                    days from the date hereof, in the amount of $50,000, less
                    any applicable withholding.

              (iii) You shall have the option to purchase the 1999 Audi A6
                    automobile you currently have access to as part of your
                    employment with the Company for $500.00; provided that you
                    furnish written notice to the Company of your exercise of
                    such option on or before the Separation Date and make
                    payment for such automobile within fifteen (15) days
                    thereafter.

              (iv)  The Company agrees that you shall continue to be entitled to
                    the same indemnification to which you were entitled in your
                    role as an employee, officer and/or director of the Company,
                    to the extent permitted by Delaware law, the Company's
                    Certificate of Incorporation and the Company's By-laws and
                    shall include coverage pursuant to NAC's then-current
                    directors and officers insurance policy (if any).

              C. The Company shall continue your enrollment in the following
     insurance plans (to the extent you are covered thereby on the Separation
     Date) through the end of the Payment Period, provided that such plans
     permit continued enrollment: Dental; Medical; Vision Care; Life, Accidental
     Death and Dismemberment; Supplemental Life Insurance for Officers;

                                       2
<PAGE>   3

     Long-term Disability; and Short-term Disability. If any plan does not
     permit continued enrollment, then, to the extent permitted by COBRA, you
     shall elect to continue your coverage for such plan(s) and the Company
     shall reimburse you for your out-of-pocket costs in connection with such
     continued coverage through the end of the Payment Period. You shall also be
     entitled to continue your participation in the Company's 401(k) Savings
     Plan through the end of the Payment Period, although the obligation of the
     Company to make contributions thereto on your behalf shall cease on the
     Separation Date. The Company will take steps to cause the employee to be
     fully vested in the Company's 401(k) Savings Plan as of the Separation
     Date; provided, however, that the 401(k) plan permits such vesting and
     provided, further, that neither the taking of such steps nor such vesting
     would require any out-of-pocket costs to be borne by the Company. All other
     programs and benefit coverages available to you as an employee or officer
     of NAC shall cease in accordance with the terms of the program or benefit
     coverage as of the Separation Date; provided, however, that nothing herein
     or in the General Release shall limit or terminate your rights, if any, (a)
     to indemnification as a former employee or officer of NAC pursuant to
     applicable law and NAC's by-law and charter provisions pertaining thereto,
     (b) for coverage pursuant to NAC's then-current directors and officers
     insurance policy, (c) to health care coverage and any other benefits
     required to be provided under COBRA, (d) with respect to any rights in any
     pension or other retirement program to the extent that such rights have
     vested on or prior to the Separation Date; or (e) with respect to your
     rights in the Company's 401(k) Savings Plan, to the extent that such rights
     have vested on or prior to the Separation Date, or with respect to such
     additional rights as may be created as a result of your continued
     participation in such plan through the end of the Payment Period as
     provided above.

              D. Subject to the provisions of Section 9 hereof, you agree to
     provide reasonable cooperation with NAC, its counsel and its insurance
     carriers in the defense or prosecution of any claims brought by or against
     NAC.

5.   You acknowledge that you have no entitlement to receive the payments set
     forth in subsection 4B hereof, other than in consideration for your
     execution of the Original Release, the Bringdown Release and your
     performance of the provisions of this Agreement. You confirm that no other
     monies or other compensation are due to you other than as are provided for
     in section 4 of this Agreement. Nothing in this Agreement shall abrogate or
     otherwise relieve you of your duty to preserve the attorney-client
     privilege existing in favor of NAC as a result of the performance of your
     duties during the period that you served as general counsel to the Company.

6.   In the event that any prospective employer or any other individual contacts
     the Company for a reference regarding you, the Company shall confirm that
     you were employed by the Company in the position(s) of "Vice President,
     General Counsel and Secretary" and the length of your employment. In the
     event that any prospective employer or any other individual requests
     information from the Company regarding the circumstances surrounding your
     leaving the employ of the Company, the Company will furnish a copy of the
     reference letter in the form annexed hereto as Exhibit C or shall orally
     communicate the information

                                       3
<PAGE>   4

     contained therein. The Company shall not, and shall instruct its officers,
     directors, management and employees not to, make or publish any comment
     that is defamatory, disparaging or otherwise critical of you or that would
     otherwise tend to have an adverse effect upon your professional reputation.

7.   You acknowledge that you have acquired Confidential Information (as defined
     below) while working for NAC and Business Records (as defined below) of
     NAC. It is understood by you and the Company that the General Release,
     Company Release and non-disclosure provisions of this Agreement are
     essential consideration for this Agreement and an award of damages may be
     made for a violation thereof. Any such award shall not affect the
     enforceability of the General Release or Company Release.

          A.  As used herein, "CONFIDENTIAL INFORMATION" means any proprietary,
              confidential and/or other non-public information of, relating to
              or regarding the business or interests of the including, without
              limitation, information pertaining to the Company's business,
              business plans, completed or pending transactions, board meetings,
              personnel or development plans and activities, trade secrets,
              databases, company policies, procedures and techniques,
              correspondence, agreements, confidentiality agreements, offering
              packages, business descriptions and profiles, financial
              information, product literature and technical projects of,
              regarding or relating to the Company, and any research datum or
              result, report, analysis, study, invention, customer and/or
              prospect list, process or other work product developed by or for
              the Company, including, without limitation, that developed by you,
              whether on the premises of the Company or elsewhere.
              Notwithstanding the foregoing, the provisions of this Agreement
              shall not apply to any Confidential Information to the extent, but
              only to the extent, that the same is, or has become, publicly
              known under circumstances involving no breach of this Agreement or
              has been disclosed pursuant to order or requirement of a court,
              administrative agency or other governmental body of competent
              authority, PROVIDED that the Company has been given appropriate
              and reasonable notice of such proceeding and a reasonable
              opportunity to contest such disclosure.

          B.  All business, financial, product and technical records,
              information and literature relating to the business of the Company
              (all such business, financial, product and technical records,
              information and literature being hereinafter referred to
              collectively as "BUSINESS RECORDS"), including, without
              limitation, Confidential Information, agreements, confidentiality
              agreements, papers, databases, contact records, documents and
              correspondence and studies containing information relating to the
              Company, and any copies of any of the foregoing, in all cases
              irrespective of the manner in which such information was obtained
              or is kept or stored, made or kept by you or under your
              possession, custody or control or in the possession, custody or
              control of any agent and representative of yours shall be and
              remain the sole and exclusive property of the Company and shall be
              surrendered to the Company on or before the Separation Date.

                                       4
<PAGE>   5

          C.  You agree not to use or disclose to any person or entity (other
              than your attorney, who shall keep such information confidential)
              any such Confidential Information, whether for your benefit or for
              the benefit of another, and you will hold and treat such
              information as confidential unless you have specific written
              authorization from NAC to use or disclose it.

          D.  By the Separation Date, you agree to return to NAC any and all
              Business Records and other property of NAC in your possession, or
              otherwise under your control, including, without limitation, all
              documents, data files, computer disks, other materials and all
              copies thereof. You shall not, and shall cause your agents,
              representatives and affiliates not to, retain, publish or
              disclose, or otherwise use, without the prior written consent of
              the CEO of the Company, any Business Records of the Company.
              Further, except in the ordinary course of your current activities,
              you shall not, and shall not allow or permit any representative or
              agent of yours to, delete any scheduling or other information with
              respect to any pending activities, or otherwise delete, move,
              remove or otherwise distort or alter any Business Records
              (regardless of the form or medium in which the same may be
              maintained).

          E.  The foregoing provisions regarding Business Records shall not
              apply to any Business Records that have been filed with the SEC or
              are otherwise part of the public domain, to copies of the
              Company's indemnification provisions or to the Company's
              then-current directors and officers insurance policy. The Company
              agrees that it shall provide you with copies of such insurance
              policy during each of the next three (3) renewal periods.

          F.  Except as otherwise provided in this Agreement, you agree that you
              will not, directly or indirectly, for yourself or on behalf of any
              other person, firm, association or agency, make or publish any
              comment that is defamatory, disparaging or otherwise critical of
              the Company, its products, transactions, businesses, officers,
              directors, attorneys, agents, management, employees or operations.

          G.  It shall not be a violation of this Agreement if you are required
              to disclose any Confidential Information or Business Records
              during testimony you give under oath PROVIDED that the Company has
              been given appropriate and reasonable notice of such proceeding
              and a reasonable opportunity to contest such disclosure.

8.   You acknowledge that a breach by you of any portion of section 7 of this
     Agreement or the General Release could cause the Company irreparable injury
     and damage. Because it would not be possible to determine the true and
     complete extent of the injury or damage to the Company in the event of such
     a breach, you agree that any breach of the terms of this Agreement will
     subject you to liability to NAC for immediate injunctive relief and all
     damages awarded by the Court; it being agreed that each party shall bear
     its own attorney's fees and costs in bringing or defending the action. You
     further agree that in the event of a

                                       5
<PAGE>   6

     material breach of the terms of this Agreement as determined by a court of
     competent jurisdiction, in whole or in part, any amounts paid to you
     pursuant to section 4 shall become immediately due and payable to NAC, no
     further payments under section 4, if any, shall be due to you and NAC will
     have and may pursue its legal remedies for repayment, including, but not
     limited to, the remedy of recession for breach of contract, fraud and
     misrepresentation.

9.   Subsequent to the Separation Date:

              A. If the Company requests you to participate in or expend time or
     efforts in connection with any Company-related matter, the Company shall
     compensate you at the rate of $75.00 per hour for the actual number of
     hours you spend on such matters. The Company agrees that you may refuse a
     request to participate in or expend time or efforts in connection with any
     Company-related matter, provided, however, that you agree that:
                 (i)    during the 30 days immediately following the Separation
                        Date, you shall provide to the Company up to two (2)
                        hours of telephonic consultation per week; and

                 (ii)   during the 31st through 60th days immediately following
                        the Separation Date, you shall provide to the Company up
                        to one and one-half (1.5) hours of telephonic
                        consultation per week.

                 B.     If a third party requests, by subpoena or otherwise, you
                        to participate in or expend time or efforts in
                        connection with any Company-related matter, you shall
                        promptly contact the Company's Chief Executive Officer
                        and cooperate fully with the Company and its counsel or
                        other advisors, in which event you shall be entitled to
                        the same hourly rate as set forth in the previous
                        subsection.

10.
                 A.     You affirm that you have not caused or permitted to be
                        filed on your behalf, nor will you cause or permit to be
                        filed or asserted on your behalf, any charge, complaint,
                        grievance, or proceeding before any federal, state or
                        local administrative agency or court, or any other
                        forum, against the Company, its officers, directors and
                        employees. In the event that any charge, complaint,
                        grievance, arbitration, action or other proceeding was
                        or is filed by you, or on your behalf (other than to
                        receive the consideration promised to you in section 4
                        of this Agreement and other than a claim under the Age
                        Discrimination in Employment Act of 1967, as amended),
                        you agree that you will not obtain or accept any
                        recovery or relief therefrom or provide any testimony
                        unless required to do so by subpoena. In the event that
                        such claim falls under ADEA, NAC will have a set off
                        against any judgment in your favor equal to the full
                        amount of the consideration promised to you in section 4
                        of this Agreement. You further agree to perform and
                        authorize the Company to perform all acts necessary to
                        obtain the immediate withdrawal and/or dismissal with
                        prejudice, at your own cost and expense, of each such
                        claim and to pay the legal fees and costs incurred by
                        the Company for actions taken to defend against and to
                        seek to obtain the

                                       6
<PAGE>   7

                        dismissal of any action or claim that is filed or
                        asserted. You further acknowledge that the filing of any
                        action, other than one to enforce any provision of this
                        Agreement, would be a breach of this Agreement and would
                        make you liable for the repayment to the Company of any
                        and all of the payments set forth in section 4 hereof
                        that were paid to you.

                 B.     The Company affirms that it has not caused, nor
                        permitted to be filed on its behalf, any charge,
                        complaint, grievance, or proceeding before any federal,
                        state or local administrative agency or court, or any
                        other forum, against you.

11.  This Agreement shall be binding on you and the Company, our respective
     heirs, executors, administrators, successors and assigns, and shall be
     construed under the laws of the State of Ohio to preserve its
     enforceability and to effect the general release, settlement and waiver of
     all claims of each and every kind except those specifically preserved
     hereunder. A court may modify or delete any otherwise unenforceable clause.

12.  You and the Company agree to be legally bound by this Agreement, and hereby
     agree that this Agreement can be modified only by a written memorandum
     signed by both you and the Company, which recites the specific intent to
     modify this Agreement. This Agreement is subject to approval by the
     Company's Board of Directors.

13.  The terms of this Agreement and the General Release attached hereto are the
     product of mutual negotiation and compromise between you and the Company.
     The meaning, effect and terms of this Agreement and the General Release
     have been fully explained to you, and you understand that this Agreement
     and the General Release settles, bars, and waives any and all claims that
     you have or could possibly have against the Company, unless prohibited from
     releasing such claim by law or unless expressly reserved hereunder. You

                           NATIONAL AUTO CREDIT, INC.

To Whom It May Concern:

         This is to inform you that Ray Varcho worked at National Auto Credit,
Inc. as Vice President, General Counsel and Secretary from October, 1997 to
June, 2001. Mr. Varcho had a wide variety of duties and responsibilities
commensurate with such a position, all of which he performed in an exemplary
fashion. Ray was a loyal and hard-working employee who contributed to the
success of NAC. His separation from the Company was due solely to the fact that
NAC terminated operations in Cleveland, Ohio. I strongly recommend Ray Varcho
for a position with your Company.
