Dear Mr. Brooks:

         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 DHB Capital Group,  Inc. ("DHB")
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,  DHB is delivering  its note in the  principal  amount of $100,000 in
payment for the option.  The form of the DHB note is attached  hereto as Exhibit
A.

         3. Term of the  Option.  The  option  shall  expire at the later of (a)
January  8,  1997 or (b)  consummation  or  termination  for any  reason  of the
Agreement  and  Plan of  Reorganization  between  Lehigh  and DHB  (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).

         5.  Standstill  Agreements.  Until December 31, 2001, DHB 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,  (b) up to 5% of
the common stock of Lehigh through open market or privately negotiated purchases
which are consummated prior to October 15, 1996, and (c) up to an additional 10%
of the common stock of Lehigh through open market or



privately  negotiated purchases in the event any new Schedule 13D is filed after
the date  hereof;  (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 to 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 DHB 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,  cannot be  transferred,  assigned,  hypothecated  or pledged
(either  directly or  indirectly) by DHB in any fashion to any entity without my
prior written  consent.  For this  purposes,  a "change of control" of DHB would
constitute a transfer of the option for which my prior written  consent would be
required.

         7.  Indemnification and Contribution.  DHB 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 DHB with prompt  notification of any matter which
could give rise to a claim for  indemnification;  DHB 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  DHB'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 DHB based on the  relative  benefits
obtained by it,  which  shall be assumed to be 99%.  DHB 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; can 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
                                                  --------------------------
                                                  Salvatore J. Zizza

Agreed and accepted as of the date first written above.
