(3) years after the Closing Date unless a claim for indemnification shall be

by any La-Man Protected Party resulting directly or indirectly from: 

                                       18
<PAGE>
 
               (a)  any alleged untrue statement contained in any of the
representations and warranties made by Manfredi and the Company in Article 3 of

               (b)  any failure to comply with any of the covenants or
agreements of Manfredi and the Company contained in this Agreement or any
Ancillary Documents.

     SECTION 6.4    INDEMNIFICATION OF MANFREDI. From and after the Closing Date
and subject to the provisions of Sections 6.1, La-Man shall indemnify and hold

any resulting directly or indirectly from:

               (a)  any alleged untrue statement contained in any of the
representations and warranties made by La-Man in this Agreement or in any La-Man
Ancillary Documents; or

               (b)  any failure by La-Man to comply with the covenants or
agreements of La-Man contained in this Agreement or in any La-Man Ancillary
Documents.

     SECTION 6.5    INDEMNIFICATION FOR THIRD PARTY CLAIMS.  The following
procedures shall be applicable with respect to indemnification for third party
claims arising in connection with any provision of this Article 6.

               (a)  Promptly after receipt by the party seeking indemnification
hereunder (an "Indemnitee") of written notice of the assertion or the
commencement of any claim, liability or obligation by a third party, whether by
legal process or otherwise (a "Claim"), with respect to any matter referred to
in Section 6.3 or Section 6.4 hereof, as the case may be, the Indemnitee shall
give written notice thereof (the "Notice") to the person from whom
indemnification is sought pursuant hereto (an "Indemnitor") and shall thereafter
keep the Indemnitor reasonably informed with respect thereto, provided that
failure of the Indemnitee to give the Indemnitor prompt notice as provided
herein shall not relieve the Indemnitor of its obligations hereunder unless such
failure alone and not in conjunction with other factors results in (i) a default
judgment, (ii) the expiration of the time to answer a complaint, or (iii) the
inability of the Indemnitee to adequately defend against such Claim.  In case
any such Claim is brought against any Indemnitee, the Indemnitor shall be
entitled to assume the defense thereof, by written notice of its intention to
the Indemnitee within thirty (30) days after receive of the Notice, with counsel
reasonably satisfactory to the Indemnitee at the Indemnitor's own expense.
Notwithstanding the assumption by the Indemnitor of the defense of any Claim as
provided in this Section 7.5(a), the Indemnitee shall be permitted to join in
the defense of such claim and to employ counsel at its own expense.

               (b)  If the Indemnitor shall fail to notify the Indemnitee of its
desire to assume the defense of any such Claim within the prescribed period of
time, or shall notify the Indemnitee that it will not assume the defense of any
such Claim, then the Indemnitee shall assume the defense of any such Claim, in
which event it may do so in such manner as it may

                                       19
<PAGE>
 
deem appropriate. The Indemnitor shall be permitted to join in the defense of
such Claim and to employ counsel at its own expense.

               (c)  No Indemnitee shall make any settlement of any Claim which
would give rise to liability on the part of an Indemnitor hereunder without the
written consent of the Indemnitor, which consent shall not be unreasonably
withheld. If a firm written offer is made to settle a Claim and the Indemnitor
desires to accept such settlement offer, but the Indemnitee elects not to
consent thereto, then the Indemnitee may continue to contest or defend such
Claim; provided, however, that the total maximum liability of the Indemnitor to
indemnify or otherwise reimburse the Indemnitee in accordance with this
Agreement with respect to such Claim shall be limited to and shall not exceed
the amount of the settlement offer rejected by the Indemnitee, plus reasonable
out-of-pocket costs and expenses (including attorneys' fees) to the date of
notice that the Indemnitor desires to accept such settlement offer.

               (d)  Amounts payable by an Indemnitor to an Indemnitee under
Section 6.3 or Section 6.4 hereof, as the case may be, shall be payable by the
Indemnitor as incurred by the Indemnitee.

ARTICLE 7.   NON-COMPETITION COVENANT

     SECTION 7.1    NON-COMPETITION.  For a period of 24 consecutive months
following the Closing Date, except as otherwise approved in writing by La-Man,
Manfredi shall not, directly or indirectly and whether as principal, agent,
officer, director, employee, consultant or otherwise, alone or in association
with any other Person, carry on, be engaged in, take part in, render services
to, or own, share in the earnings of, or invest in the Securities of, any Person
which is engaged in any state or territory in the United States in any business
operations or activities in competition with or otherwise in whole or in part
similar to the Business ("Similar Business"); provided, however, that the
foregoing shall not be deemed to preclude Manfredi from investing in securities
of any Person engaged in any Similar Business (but without otherwise
participating in such Similar Business) if (a) such Securities are listed on any
national securities exchange or are registered under Section 12(g) of the
Exchange Act, (b) such investment does not exceed, in the case of any class of
securities of any one issuer, 2.0% of such issued and outstanding securities of
such issuer, and (c) such investment would not directly or indirectly prevent
the transaction of business by the Company, La-Man or any their Affiliates in
any state, district, territory or possession of the United States or any
governmental subdivision, agency or instrumentality thereof by virtue of any
Law.

     SECTION 7.2    SCOPE; ENFORCEABILITY. Manfredi covenants and agrees that:
(a) this non-competition covenant is reasonable in scope, geographic area and
duration; (b) if such non-competition covenant is breached prior to the
completion of the 24-month period referred to above, such term shall begin anew,
immediately following such breach; and (c) the actual damages which La-Man may
sustain in the event of any such breach are difficult or impossible to ascertain
and that, in the event of such breach, La-Man shall be entitled to enforce its
rights hereunder by specific performance or by other action at law or in equity.

writing signed on behalf of each of the parties hereto.

               (b)  No action taken pursuant to this Agreement, including any
investigation by or on behalf of any party hereto, shall be deemed to constitute
a waiver by the party taking such action of compliance with any agreement or
condition contained herein or in any Ancillary Document.  The waiver by any
party hereto of any condition or of a breach of any other provision of this
Agreement or any Ancillary Document shall not operate or be construed as a
waiver of any other condition or any other provision or subsequent breach.  The
waiver by any party of any of the conditions precedent to its obligations under
this Agreement shall not preclude it from seeking redress for breach of this
Agreement other than with respect to the condition so waived.  All rights and
remedies of any party to this Agreement shall be cumulative and concurrent and
may be exercised singularly, successively or concurrently, at the sole
discretion of such party and may be exercised as often as occasion therefor may
exist.

     SECTION 8.4    GOVERNING LAW; VENUE.  This Agreement shall be governed by

Agreement shall be brought against it in any state or federal court of competent
jurisdiction in Orange County, Florida and irrevocably waives any (a) right of
immunity that such party may now have or hereafter acquire from service of
process or the jurisdiction of the aforesaid courts and (b) any objection that
such party may now have or hereafter acquire to the laying of venue of any such
suit, action or proceeding in any such court. The parties hereby irrevocably
accept and submit themselves to the jurisdiction of such courts in any such
suit, action or proceeding, and agree that final judgment (with the exhaustion
of all appeals) shall be conclusive and binding in any jurisdiction in which
such party resides or owns property.

     SECTION 8.5    BINDING EFFECT; ASSIGNMENT.  This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors, assigns and legal representatives.  Neither this Agreement, nor any
right hereunder, may be assigned by any party hereto without the prior written
consent of the other parties hereto.

parties unless ordered to do so by a court, governmental or regulatory body
having jurisdiction in the premises, or unless such information is readily
ascertainable from public or published information, or trade sources, or is
already known or subsequently developed by such party independently, or was
received from a third party not under an obligation to such other party or any
of its affiliates to keep such information confidential.

     SECTION 8.7    SEVERABILITY.  This Agreement is intended to be performed in
accordance with, and only to the extent permitted by, all applicable Laws.  If
any provision of this Agreement or the application thereto to any Person or
circumstances shall, for any reason and to any extent, be invalid or
unenforceable, the remainder of this Agreement and the application of such
provision to other Persons or circumstances shall not be affected thereby, but
rather shall be enforced to the greatest extent permitted by Law.

constitute the entire agreement and understanding among La-Man, the Company and
Manfredi with respect to the subject matter hereof and thereof and supersede any
and all other agreements, arrangements and understandings among the parties with
respect to such subject matter, and no agreements, arrangements, understandings,
representations or warranties with respect to such subject matter shall be
binding upon any of the parties unless specified herein or therein.

     SECTION 8.9    NO THIRD PARTY BENEFICIARIES.  Nothing in this Agreement is
intended or shall be construed to give any person, other than the parties
hereto, and their successors and assigns in accordance with Section 8.5, any
legal or equitable right, remedy or claim under or in respect of this Agreement
or any Ancillary Documents or any provision contained herein.

     SECTION 8.10   COUNTERPARTS.  This Agreement may be executed by the parties
hereto in separate counterparts, each of which when so executed and delivered
