                         FIRSTPLUS FINANCIAL GROUP, INC.

         A Nonqualified  Stock Option (the "Option") for a total of Seventy-five
Thousand  (75,000)  shares (the  "Shares") of common  stock,  par value $.01 per
share (the "Common Stock"),  of FIRSTPLUS Financial Group, Inc. (the "Company"),
is hereby granted to William P. Benac (the "Optionee")  pursuant to the terms of
this Option Agreement (the "Option Agreement").

         Section 1.  Exercise  Price.  The exercise  price is $48.3125  for each
Share.

         Section 2. Exercise of the Option.  This Option may be exercised at any
time during the term of this Option,  in whole or in part with respect to Shares
that have vested.  Shares  subject to this Option shall vest in equal  one-third
shares on the first,  second and third  anniversaries  of the date of grant. The
committee may in its sole discretion accelerate the date on which any Option may
be  exercised.  Notwithstanding  the  foregoing,  this Option shall become fully
exercisable  upon  the  occurrence  of  certain  significant   corporate  events
described in Section 2(e) below.

               (a)  Method  of  Exercise.   Options  shall  be  deemed  properly
          exercised when:

                    (i)  the  Company  has  received   written  notice  of  such
               exercise, stating the number of Shares which are being purchased,
               delivered  to the  Company  and  signed by the  person or persons
               entitled  to  exercise  the  Option  and,  if the Option is being
               exercised by any person or persons  other than the  Optionee,  be
               accompanied by proof,  satisfactory to the Company,  of the right
               of such person or persons to exercise the Option;

                    (ii) full payment of the exercise  price of the Shares as to
               which the Option is exercised  has been  tendered to the Company;
               and

                    (iii) arrangements that are satisfactory to the Committee in
               its sole discretion have been made for the Optionee's  payment to
               the Company of the amount, if any, that the Company determines to
               be  necessary  for the  company to withhold  in  accordance  with
               applicable federal or state income tax withholding requirements.

               (b) Payment.  The exercise price of any shares purchased shall be
          paid in cash,  by  certified or cashier's  check,  by money order,  by
          personal  check (if  approved by the  Committee),  or in Common  Stock
          owned by such  Optionee (if  Optionee  owned such Common Stock for six
          months  prior to using  such  stock to  exercise  the  Option) or by a
          combination of the above. If the exercise price is paid in whole or in
          part with shares of Common  Stock of the  Company,  such Common  Stock
          shall be valued at its Fair Market Value on the date of exercise.  Any
          Common  Stock  delivered  in  satisfaction  of all or a portion of the
          exercise  price shall be duly endorsed for transfer and  assignment to
          the Company.

               (c) Restrictions on Exercise.

                         (i) This Option may not be exercised if the issuance of
                    the Shares upon such exercise  would  constitute a violation
                    of any applicable  federal or state  securities or other law
                    or valid regulation.  As a condition to the exercise of this
                    Option, the Company  may  require the  exercising  person to
                    make any agreements and undertakings that may be required by
                    any applicable law or regulation.

                                        1





                         (ii)  Shares  issued  upon the  exercise of this Option
                    without registration of such Shares under the Securities Act
                    of  1933,  as  amended  (the  "Act"),  shall  be  restricted
                    securities  subject  to the terms of Rule 144 under the Act.
                    The certificates  representing any such Shares shall bear an
                    appropriate  legend  restricting  transfer  and the transfer
                    agent  of  the   Company   shall  be  given  stop   transfer
                    instructions with respect to such Shares.

                         (iii) This Option may not be exercised  if, in the good
                    faith  judgment of the Board of  Directors of the Company or
                    the Board's  designee,  the issuance of the Shares upon such
                    exercise or the sale  thereof  would  violate the  Company's
                    written policy regarding sales or purchases of the Company's
                    Common  Stock then in effect or if the  Company  proposes to
                    file  a  registration  statement  with  respect  to  selling
                    additional  shares  of the  Company's  Common  Stock and the
                    underwriters  reasonably  believe  that the  issuance of the
                    Shares  upon  such   exercise  or  the  sale   thereof  will
                    jeopardize the success of the offering.

               (d)  Surrender of Option.  If this Option is exercised in part by
          the Company,  the Optionee  shall,  if requested,  deliver this Option
          Agreement and any other written agreements with respect to this Option
          to the Company to be endorsed  with a notation  of such  exercise  and
          returned to the Optionee.

               (e) Certain  Corporate Events. On the date thirty (30) days prior
          to any occurrence described in this Section (2)(e)(i),  (ii) or (iii),
          but only where  such  anticipated  occurrence  actually  takes  place,
          notwithstanding  the exercise schedule in this Option Agreement,  this
          Option shall immediately become exercisable in full where there (i) is
          any  transaction   (which  shall  include  a  series  of  transactions
          occurring within 60 days or occurring pursuant to a plan) that has the
          result  that  shareholders  of the  Company  immediately  before  such
          transaction  cease to own at least 51% of (x) the voting  stock of the
          Company or (y) any entity that results from the  participation  of the
          Company in a reorganization, consolidation, merger, liquidation or any
          other form of corporate transaction;  (ii) is a merger, consolidation,
          reorganization,  liquidation  or dissolution in which the Company does
          not survive;  (iii) is a sale, lease, exchange or other disposition of
          all or substantially all the property and assets of the Company.

         Section 3. Term of Option.  This Option may not be exercised  after the
expiration  of ten (10)  years  from the Date of Grant and is subject to earlier
termination  as  provided in Section 4. In  addition,  this Option is subject to
cancellation  by the Company upon a significant  corporate  event as provided in
Section  4 below.  This  Option  may be  exercised  during  such  times  only in
accordance with the terms of this Option Agreement.

         Section 4.  Termination of Option Period.

                    the Company or a subsidiary of the Company,  as the case may
                    be, regardless of the reason therefor other than as a result

                    termination   of  the  Optionee's   employment,   status  as
                    director,  or consulting  contract or advisory services,  as
                    the case may be, with the Company or a subsidiary for cause;

                         (ii) one (1) year after the date on which the  Optionee

                    (6) months after the date on which the  Optionee  shall die,
                    if the  Optionee's  death shall occur during the thirty (30)
                    day  period  described  in Section  4(a)(i) or the  one-year
                    period described in Section 4(a)(ii);

          may,  by giving  written  notice  (a  "Cancellation  Notice")  cancel,

          remains  unexercised on such date. Such  Cancellation  Notice shall be
          given a reasonable period of time (but not less than 15 days) prior to
          the proposed date of such cancellation, and may be given either before
          or after shareholder approval of such transaction.

         Section 5. Adjustment of Shares.

               (a) If at any time  while  unexercised  Options  are  outstanding
          hereunder,  there  shall be any  increase or decrease in the number of
          issued and outstanding  shares of Common Stock through the declaration
          of a stock  dividend or through any  recapitalization  resulting  in a
          stock  split-up,  combination or exchange of shares,  then and in such
          event appropriate adjustment shall be made in the number of Shares and
          the exercise  price per Share thereof then subject to this Option,  so
          that the same  proportion  of the  Company's  issued  and  outstanding
          shares shall remain subject to purchase at the same aggregate exercise
          price.

               (b) The Company may change the terms of this Option, with respect
          to the exercise  price or the number of Shares subject to this Option,
          or both,  when, in the Company's  sole  discretion,  such  adjustments
          become appropriate by reason of any significant corporate transaction.

               (c) Except as otherwise  expressly  provided herein, the issuance
          by the  Company  of  shares  of its  capital  stock of any  class,  or
          securities  convertible  into  shares of  capital  stock of any class,
          either in  connection  with direct sale or upon the exercise of rights
          or warrants to subscribe  therefor,  or upon  conversion  of shares or
          obligations  of  the  Company  convertible  into  such shares or other

                                        3





         securities, shall not affect, and no adjustment by reason thereof shall
         be made with respect to the number of or exercise  price of Shares then
         subject to this Option.

               (d)  Without  limiting  the  generality  of  the  foregoing,  the
          existence  of this Option  shall not affect in any manner the right or
          power of the Company to make,  authorize or consummate  (i) any or all
          adjustments,  recapitalizations,  reorganizations  or other changes in
          the Company's  capital  structure or its business;  (ii) any merger or
          consolidation  of the Company;  (iii) any issue by the Company of debt
          securities, or preferred or preference stock that would rank above the
          Shares subject to this Option;  (iv) the dissolution or liquidation of
          the Company;  (v) any sale,  transfer or assignment of all or any part
          of the assets or business of the Company;  or (vi) any other corporate
          act or proceeding, whether of a similar character or otherwise.

          Section 6.  Non-Assignability  of  Option.  This  Option  may  not  be
transferred  or  assigned by the  Optionee  other than by will or by the laws of
descent and distribution.

         Section 7.  Issuance of Shares.  No person shall be, or have any rights
or privileges of, a shareholder of the Company with respect to any of the Shares
subject to this Option unless and until  certificates  representing  such Shares
have been issued and delivered to such person.  As a condition of an issuance of
a stock  certificate  for Shares,  the Company  may obtain  such  agreements  or
undertakings, if any, as it may deem necessary or advisable to assure compliance
with any provision of this Option Agreement or any law or regulation, including,
but not limited to, the following:

               (a) The Optionee's representation and warranty to the Company, at
          the time the  Option is  exercised,  that the  Shares to be issued are
          being  acquired for  investment and not with a view to, or for sale in
          connection with, the distribution of any such Shares; and

               (b) the  Optionee's  representation,  warranty or agreement to be
          bound  by any  legends  that  are,  in  the  opinion  of the  Company,
          necessary  or  appropriate  to  comply  with  the  provisions  of  any
          securities  law deemed by the Company to be applicable to the issuance
          of the Shares and to be endorsed  upon the  certificates  representing
          the Shares.

         Section 8.  Administration of this Option.

               (a) The determinations and the interpretation and construction of
          any  provision  of this  Option  by the  Company  shall be  final  and
          conclusive.

               (b) Subject to the express provisions of this Option, the Company
          shall have the authority,  in its sole and absolute  discretion (i) to
          adopt,  amend, and rescind  administrative  and interpretive rules and
          regulations  relating to this  Option;  (ii) to construe  the terms of
          this Option;  (iii) as provided in Section 5, upon  certain  events to
          make  appropriate  adjustments  to the  exercise  price and  number of
          Shares   subject  to  this   Option;   and  (iv)  to  make  all  other
          determinations  and perform all other acts  necessary or advisable for
          administering   this  Option,   including   the   delegation  of  such
          ministerial   acts  and   responsibilities   as  the   Company   deems
          appropriate. The Company may correct any defect or supply any omission
          or reconcile any inconsistency in this Option in the manner and to the
          extent it shall deem  expedient to carry it into effect,  and it shall
          be the sole and final judge of such expediency. The Company shall have

                                       4





          full discretion to make all  determinations on the matters referred to
          in this Section 8(b), and such determinations  shall be final, binding
          and conclusive.

GOVERNED BY THE LAWS OF SUCH STATE.

         Section 11.  Notices.  All notices  and other  communications  that are
required to be or may be given under this Option  Agreement  shall be in writing

Agreement.

         Section 12.  Miscellaneous.

               (a)  The  grant  of  this  Option  is in  addition  to any  other

          plans of the Company or other  benefits with respect to the Optionee's
          position with or relationship to the Company or its subsidiaries. This
          Option  shall not confer upon the Optionee the right to continue as an
          employee,  consultant  or advisor,  or  interfere  in any way with the
          rights  of the  Company  to  terminate  the  Optionee's  status  as an
          employee, consultant or advisor.

               (b) The members of the Board of  Directors  of the Company  shall
          not be liable for any act, omission or determination  taken or made in
          good  faith  with  respect to this  Option,  and  members of the Board
          shall,  in  addition  to  all  other  rights  of  indemnification  and
          reimbursement, be entitled to indemnification and reimbursement by the
          Company in respect of any claim,  loss,  damage,  liability or expense
          (including  attorneys' fees, the costs of settling any suit,  provided
          such settlement is approved by independent  legal counsel  selected by
          the Company, and amounts paid in satisfaction of a judgment,  except a
          judgment  based on a finding of bad faith)  arising  from such  claim,
          loss, damage, liability or expense to the full extent permitted by law
          and under any directors' and officers'  liability or similar insurance
          coverage that may from time to time be in effect.

               (c) Any issuance or transfer of Shares to the Optionee, or to the
          Optionee's legal  representative,  heir, legatee,  or distributee,  in
          accordance  with the provisions of this Option,  shall,  to the extent
          thereof,  be in full  satisfaction of all claims of such persons under
          this  Option.  The  Company may  require  the  Optionee,  or any legal
          representative,  heir, legatee or distributee as a condition precedent
          to such  payment or  issuance  or  transfer  of  Shares,  to execute a
          release and receipt for such payment or issuance or transfer of Shares
          in such form as it shall determine.

               (d) Neither the Board nor the Company guarantees Shares from loss
          or depreciation.

                                       5





               (e) All expenses incident to the administration,  termination, or
          protection  of this Option,  including,  but not limited to, legal and
          accounting fees, shall be paid by the Company; provided,  however, the
          Company may  recover any and all  damages,  fees,  expenses  and costs
          arising out of any actions  taken by the Company to enforce its rights
          under this Option.

               (f) Records of the Company shall be  conclusive  for all purposes
          under this Option, unless determined by the Board to be incorrect.

          shall be by resolution  of the Board or by a person  authorized to act
          by resolution of the Board.

               (h) If any  provision  of this  Option is held to be  illegal  or
          invalid for any reason,  the illegality or invalidity shall not affect
          the remaining  provisions of this Option,  but such provision shall be
          fully severable, and this Option shall be construed and enforced as if
          the  illegal or invalid  provision  had never  been  included  in this
          Option.

               (i)  Whenever  any notice is  required  or  permitted  under this
          Option,  such notice must be in writing and  personally  delivered  or
          sent by mail or delivery by a nationally  recognized  courier service.
          Any notice  required or permitted  to be  delivered  under this Option
          shall be deemed to be delivered on the date on which it is  personally
          delivered,  or, if mailed,  whether  actually  received or not, on the
