                               OVERALL AGREEMENT
                               -----------------

2.   POSITIONS AND DUTIES
     --------------------

     (a) The Parties expect that the services to be provided by the Executive
for the Subsidiaries will change from time to time as the needs of the
Subsidiaries change. Nevertheless, the only employment relationship shall be

shall be by mandates, either remunerated or otherwise.  Such mandates, the
amount of the Executive's services required by any of the Subsidiaries, and the
remuneration to be paid by any of the Subsidiaries may be changed from time to
time by action of the Subsidiaries.  However, at all times, the total
remuneration from the employment relationship and the remunerated mandates shall
be as specified in this Overall Agreement.

and attention to the performance of services for the Subsidiaries, allocating
such time and attention generally according to the needs of such Subsidiaries.

3.   COMPENSATION AND RELATED MATTERS
     --------------------------------

     (a) Base Compensation.  During the period of the Executive's engagement
         -----------------                                                  
hereunder, the Company shall cause the Subsidiaries to compensate the Executive
in equal instalments in accordance with their normal payroll practices or in
accordance with the decisions taken by the competent organs of the Subsidiaries
with regard to the remuneration granted to the Executive for the execution of
his mandates, but not less frequently than monthly.  Such compensation (the
"Base Compensation") shall be ECU 300,147 (equivalent to US$325,000 converted at
the exchange rate of 0.92436 US$ per ECU, the rate in effect as of the Effective
Date) gross per annum, allocated in the same proportions as in Section 2.(c).

The payments of Base Compensation shall not in any way limit or reduce any other
obligation of the Company hereunder, and no other compensation, benefit or
payment made pursuant to this Overall Agreement shall in any way limit or reduce
the obligation of the Company to cause the payment of the Executive's Base
Compensation as hereunder provided.  The Base Compensation payable may not be
reduced.  Any increase in the Base Compensation shall become effective at the
time indicated by the Company without the need for an amendment to this Overall
Agreement.

     (b) Annual Adjustment.  Each year, the Company shall cause the Subsidiaries
         -----------------                                                      
to make a lump sum adjustment to the Executive's Base Compensation (the "Annual
Adjustment") for such year only, equal to an amount between zero and 59.2308%of
the Base Compensation.  The total annual adjustment amount will be allocated in
the same proportions as in Section 2.(c) above. The Annual Adjustment shall
consist of a Target Adjustment and a Project Adjustment (each as defined below),
determined as follows:

     (i) The "Target Adjustment" shall be zero if the EBIT Attainment Percentage
  (as defined below) is less than eighty percent (80%).  Otherwise, the 

                                     Page 2
<PAGE>
 
  "Target Adjustment" shall be an amount equal to one-half of the EBIT
  Attainment Percentage multiplied by 53.8462% of the Base Compensation. The
  "EBIT Attainment Percentage" shall be determined as follows:

<TABLE>
<CAPTION>
<S>                                          <C> 
                                             THEN THE EBIT ATTAINMENT PERCENTAGE
IF THE EBIT (AS DEFINED BELOW) IS:           SHALL BE:
 
 
less than the Minimum EBIT Target (as        Zero percent (0%)
 defined below) for the Company's
 preceding fiscal year
 
equal to the Minimum EBIT Target for the     Eighty percent (80%)
 Company's preceding fiscal year
 
greater than the Minimum EBIT Target for     The sum of (x) eighty percent (80%), plus
 the Company's preceding fiscal year, but    (y) the product of twenty percent (20%)
 less than the Annual EBIT Target (as        multiplied by a fraction, the numerator of
 defined below) for the Company's            which shall be the excess of (i) the EBIT
 preceding fiscal year                       of the Company for the Company's
                                             preceding fiscal year over (ii) the Minimum
                                             EBIT Target for the Company's preceding
                                             fiscal year, and the denominator of which
                                             shall be the excess of the Annual EBIT
                                             Target for the Company's preceding fiscal
                                             year over the Minimum EBIT Target for
                                             the Company's preceding fiscal year
 
equals the Annual EBIT Target for the        One hundred percent (100%)
 Company's preceding fiscal year
 
greater than the Annual EBIT Target for      The sum of (x) one hundred percent
 the Company's preceding fiscal year, but    (100%) plus (y) the product of twenty
 less than the Maximum EBIT Target (as       percent (20%) multiplied by a fraction, the
 defined below) for the Company's            numerator of which shall be the excess of
 preceding fiscal year                       (i) the EBIT of the Company for the
                                             Company's preceding fiscal year over (ii)
                                             the Annual EBIT Target for the
                                             Company's preceding fiscal year, and the
                                             denominator of which shall be the excess
                                             of the Maximum EBIT Target for the
                                             Company's preceding fiscal year over the
                                             Annual EBIT Target for the Company's
                                             preceding fiscal year

equal to or greater than the Maximum         One hundred twenty percent (120%)
 EBIT Target for the preceding year
</TABLE>

     (ii) With respect to each fiscal year of the Company ending after January
31, 1998, on or before March 15 of each such year, the board of directors of

                                     Page 3
<PAGE>
 
the Company (the "Board") shall determine the "Annual EBIT Target," the "Minimum
EBIT Target" and the "Maximum EBIT Target" for such fiscal year. Promptly after
such targets have been determined, the Company shall provide written notice
thereof to the Executive. The EBIT Targets determined by the Board are expected
to be reasonably achievable in the good faith judgment of the Board, it being
understood that the Maximum EBIT Targets determined by the Board shall generally
reflect a more aggressive, "stretch" budget, and the Minimum EBIT Targets
determined by the Board shall generally reflect an improvement over actual EBIT
for the prior fiscal year. The Board shall have the right, acting unilaterally
and in good faith, to adjust the Annual EBIT Target, the Minimum EBIT Target and
the Maximum EBIT Target upon the occurrence of any acquisition, disposition or
other significant event that occurs with respect to The Company after such
targets have been determined. For purposes of this Section 3.(b), "EBIT" shall
mean, for any period, the Company's consolidated earnings (excluding
extraordinary gains and losses and gains or losses from the sale of fixed assets
outside of the ordinary course of business) from continuing operations before
interest and taxes for such period, and EBIT is expected to be determined on the
same basis as the Annual EBIT Target, the Minimum EBIT Target and the Maximum
EBIT Target. Notwithstanding the foregoing, EBIT for any fiscal may be equitably
adjusted by the Board (solely for the purposes of Section 3.(b)(i)) to the
extent that the Company's business was not conducted in the ordinary course in
accordance with past practices.
 
     (iii)  The "Project Adjustment" shall be calculated by multiplying
21.5385% of the Base Compensation times a percentage, ranging from eighty
percent (80%) to one hundred twenty-five percent (125%), set by the Board to
reflect the extent to which the Board determines that the Executive
satisfactorily completed certain projects (the "Annual Projects") established by
the Board with respect to the Company's preceding fiscal year. The Company shall
establish Annual Projects for each fiscal year during the Term and shall provide
the Executive with a written notice of such Annual Projects, which shall
describe such Annual Projects in reasonable detail. The Annual Projects for each
of the Company's fiscal years ending after January 31, 1998 shall be established
on or before March 15 of such year. The Annual Projects for each such fiscal
year shall be developed by the Board in consultation with the Executive, and
shall, in the good faith judgment of the Board, be reasonably achievable. The
Executive acknowledges that the Annual Projects established by the Board may not
be measured by financial results or other quantifiable standards and may depend
on subjective judgments by the Board, and the Executive agrees that the
determination of the Board as to the extent to which such Annual Projects have
been satisfactorily completed shall be conclusive for all purposes, provided
that such determination shall be made in good faith.

   (c) Vacations.  The Executive shall be entitled to the number of paid
       ---------                                                        
vacation days in each calendar year determined in accordance with the vacation
policy of Samsonite GmbH as in effect immediately prior to the execution of this
Overall Agreement.

Contract, the Executive will be entitled to an indemnity upon such termination
which amounts to the greater of:

                                     Page 5

German Contract shall be equal to the lesser of:

      (i) the excess of ECU462,180 over the amount payable by Samsonite GmbH

without limitation, Articles 12 or 13 of the German Contract, or per German law
(Note: ECU231,090 is the equivalent of US$250,000 converted at the exchange rate

   (g) Neither the Company nor any of the Subsidiaries shall have any further
obligations to the Executive, except as may be provided under the express terms

accordance with the survivorship provisions of Section 12 of this Overall
Agreement.

Company or any of the Subsidiaries, whether as indemnities in lieu of notice,
severance, or otherwise, except as expressly set forth in this Agreement.  For
this purpose, the Executive hereby irrevocably authorizes any officer or
director of the Company to execute on behalf of the Executive any documentation
