Gentlemen:

         When countersigned below, this letter agreement will constitute a legal
and binding agreement between us with respect to the following matters.

         1. GRANT OF OPTION. I hereby grant to First Medical Corporation ("FMC")
an option to acquire up to 6,000,000  shares of common stock of The Lehigh Group
Inc.  ("Lehigh")  upon the terms and subject to the conditions set forth in this
letter agreement.

         2.  CONSIDERATION.  Concurrently  with the  acceptance  of this  letter
agreement,  FMC is delivering  its note in the  principal  amount of $100,000 in
payment for the option.  The form of the FMC note is attached  hereto as Exhibit
A.

         3. TERM OF THE OPTION.  The option  shall  expire at the earlier of (a)
January  15,  1997 or (b)  consummation  or  termination  for any  reason of the
Agreement and Plan of Merger between Lehigh and FMC (the "Merger Agreement").

         4.  EXERCISE  PRICE.  The price and terms  upon which the option may be
exercised  shall be governed by the Warrant  Agreement  between Lehigh and me, a
copy of which is attached hereto as Exhibit B. In the event of any inconsistency
between this letter agreement and the Warrant  Agreement,  this letter agreement
shall govern.  In order to avoid any penalties for "short swing  profits"  under
Section 16(b), to the extent  necessary this letter agreement shall be deemed to
constitute an assignment of my rights under the Warrant  Agreement.  The parties
agree to take any other actions which may be necessary to structure the exercise
of the option and the warrant so as to avoid any liability  under Section 16(b).
In order to induce the grant of this option,  FMC hereby represents and warrants
to  Salvatore  J. Zizza  that FMC has  obtained a  Commitment  from First  Union
National  Bank of Florida to lend to FMC the sum of $3,000,000 to be used by FMC
to exercise the option,  which  commitment is embodied in a commitment  letter a
copy of which is annexed hereto as Exhibit C.

         5.  STANDSTILL  AGREEMENTS.  Until December 31, 2001, FMC agrees to the
following:  (i) it shall not  acquire,  directly  or  indirectly,  any shares of
common stock of Lehigh or any voting rights with


respect  thereto,  except (a) by means of the option  granted  pursuant  to this
letter  agreement  and (b) up to 15% of the common stock of Lehigh  through open
market or privately  negotiated purchases which are consummated prior to January
15,  1997;  (ii) the only  matter for which it may solicit  proxies  from Lehigh
shareholders  is approval of the Merger  Agreement,  for which it shall vote all
shares of common  stock of Lehigh  under  its  control  or for which it  obtains
proxies in favor of the Merger  Agreement;  (iii) on all other matters submitted
for a vote of  stockholders,  it shall vote all shares of common stock of Lehigh
under  its  control  in  accordance  with  the  recommendation  of the  Board of
Directors  of Lehigh (so long as such  matter has no  detrimental  effect on the
Merger Agreement); and (iv) it shall not transfer, assign,  hypothecate,  pledge
or  otherwise  dispose of any of the shares of common  stock of Lehigh under its
control (or the voting rights attendant  thereto) without first obtaining (a) my
consent,  and (b) the agreement of the purchaser to be bound by these standstill
provisions;  provided,  however,  that FMC may sell shares  pursuant  its demand
registration right pursuant to the terms of an agreement with Lehigh dated as of
the date hereof.

         6. NON-TRANSFERABILITY OF OPTION. This letter agreement, and the option
contained  herein,  may not be  transferred,  assigned,  hypothecated or pledged
(either  directly or  indirectly) by FMC in any fashion to any entity without my
prior written  consent.  For this  purposes,  a "change of control" of FMC would
constitute a transfer of the option for which my prior written  consent would be
required.

         7.  INDEMNIFICATION AND CONTRIBUTION.  FMC agrees to indemnify and hold
me harmless  against any and all claims,  causes of action or liabilities  which
may arise from this letter  agreement  or the  exercise of the option or warrant
hereunder.  I agree to provide FMC with prompt  notification of any matter which
could give rise to a claim for  indemnification;  FMC agrees to promptly pay all
fees and expenses which I might incur in defending any such matters,  and to pay
in full  any  ultimate  liability  which  might  result.  Notwithstanding  FMC's
agreement  to provide such  indemnification,  I shall  control the  selection of
counsel and direct the defense  strategy.  In the event  indemnification  is not
available due to public policy or otherwise,  the parties shall reformulate this
provision  to provide for  contribution  by FMC based on the  relative  benefits
obtained by it,  which  shall be assumed to be 99%.  FMC agrees that it will not
prosecute or support any claim which seeks to invalidate this provision.

         8.  PROXY AT  MEETING.  Prior to the  record  date for the  stockholder
meeting at which the Merger  Agreement  shall be voted upon,  I will use my best
efforts to obtain irrevocable proxies from major stockholders  (including myself
and other  officers and  directors of Lehigh) in favor of approval of the Merger
Agreement.


         9.  MISCELLANEOUS.   This  letter  agreement:  constitutes  the  entire
agreement between us with respect to this subject; shall inure to the benefit of
my successors  and assigns;  may only be modified or amended by a writing signed
by both parties; and is governed by the laws of the state of Delaware.


                                        Very truly yours,


                                        /s/ Salvatore J. Zizza
                                        --------------------------
