                 NON-COMPETITION AND CONFIDENTIALITY AGREEMENT

         THIS NON-COMPETITION AND CONFIDENTIALITY AGREEMENT, is entered into
this 30th day of October, 2001, by the Intrepid Capital Corporation a Delaware
corporation having a principal place of business at 3652 S. 3rd St.,
Jacksonville Beach, FL 32250. ("Intrepid"), Sprayroq, Inc., a Florida
corporation, having a principal Ace of business at 4707 Alton Court, Birmingham,
Alabama 35210 (the "Company"), and Sprayroq of Ohio, Inc., an Ohio corporation,
having a principal place of business at The Carnegie Building, 75 East Market
Street, Akron, Ohio 44308 ("Buyer").

                                   WITNESSETH:

         WHEREAS, Buyer is a party to a Stock Purchase Agreement dated September
19, 2001 (the "Purchase Agreement"), pursuant to which Buyer will purchase all
of the Company's issued and outstanding capital stock from Enviroq Corporation,
A Florida Corporation ("Enviroq") and Replico Development Corporation, a
Pennsylvania corporation ("Replico").

         WHEREAS, Intrepid is a substantial shareholder of Enviroq and has
knowledge of the growth and development of the Company and its business of
supplying state-of-the-art spray-applied resinous materials and related
equipment for rehabilitation, repair and reconstruction of pipes, pipelines,
manholes, wetwells, drains, wastewater treatment facilities, manholes and other
underground infrastructure (the "Business").

         WHEREAS, prior to the consummation of the transaction provided for in
the Purchase Agreement, as an inducement for Buyer to consummate said purchase,
Buyer requires Intrepid to execute a non-competition and confidentiality
agreement by which Intrepid agrees to keep all information of the Company
confidential and to not compete with, infringe upon or inhibit the Company's
Business.

         WHEREAS, Intrepid will gain a substantial benefit from the consummation
of the transactions contemplated in the Purchase Agreement and Intrepid desires
to enter into such an agreement.

         NOW, THEREFORE, in consideration of the premises, the mutual covenants,
and agreements set forth in this Agreement, and for other good and valuable
consideration, the parties agree as follows:

         1.       Acknowledgement. Intrepid acknowledges that: (i) it has
knowledge of proprietary information which has been developed by and/or for the
Company, representing a key feature of the value of the Company to the Buyer,
including, but not limited to, information relating to the Company's methods of
operation, mixtures and formulae, and its customers and suppliers; (ii) the
Company has developed favorable relationships with the Business' employees,

                                       1

<PAGE>

customers, suppliers and others; (iii) this information and these relationships
are not generally known as held by the Company's competitors, particularly in
the form possessed by Company; (iv) these relationships are proprietary and
valuable and provide the Company with a competitive advantage, although they may
not be "trade secrets" in all respects under prevailing judicial
interpretations; and (v) that the Company would suffer severe injury to its
Business which would be difficult or impossible to calculate in amount if this
information and these relationships were known, possessed and used by a
competitor or other third-party.

         2.       Non-Competition and Non-Solicitation. Therefore, in view of
the foregoing and in consideration of benefits to be received by Intrepid from
consummation of the transactions contemplated in the Purchase Agreement,
Intrepid hereby agrees that commencing on the date of this Agreement and
continuing for a period of ten (10) years thereafter, it will not and none of
its respective affiliates will, (A) directly or indirectly, as an employer,
guarantor, principal, agent, consultant, partner, stockholder (except for
investments in publicly traded entities, so long as such investments do not
exceed three percent (3%) of the entity's issued and outstanding voting
securities), joint venturer, investor, lender, consultant or otherwise, compete
with the Buyer or the Company in the Business; or (B) solicit, hire or actively
seek to hire any employee of the Company or any affiliate of the Company, or
solicit any personnel employed by the Company or any affiliate of the Company to
terminate his or her relationship with Company, any affiliate of Company, or the
Business. The period of time set forth in this Section 2 will be extended by the
amount of time that Intrepid engages in activity in violation of this Agreement
and while the Company seeks enforcement of this Agreement.

         3.       Confidential Information. Intrepid acknowledges that while the
Company was owned by Enviroq and Replico, Intrepid had access to and acquired
confidential and proprietary information directly relating to the Business,
including, but not limited to, lists of customers and potential customers,
policy manuals, price lists, business contracts, inventions, discoveries, secret
processes, plans, methods of doing business, special needs of customers,
manufacturing methods, formulations, records, and other confidential information
relating to the Business (collectively referred to herein as the "Confidential
Information"). Intrepid hereby acknowledges that the Confidential Information is
solely the property of the Company and constitutes trade secrets of the Company,
and that Intrepid's knowledge of the Confidential Information would enable it to
compete with the Company and the Business in a manner likely to cause the
Company and the Business irreparable harm upon the disclosure or use of such
information. Accordingly, Intrepid irrevocably covenants that it will not use or
disclose, directly or indirectly, any of the Confidential Information to any
individual, firm, company or other entity or person.

         4.       Response to Legal Process Seeking Access to Information. In
the event that Intrepid becomes legally compelled (by oral questions,
interrogatories, requests for information or documents, subpoena, investigative
demand or similar process) to disclose any of the Confidential Information,
Intrepid covenants to use its reasonable best efforts to provide the Company
with prompt written notice (not less than seventy-two (72) hours) so that the
Company may seek a protective order or other appropriate remedy and/or waive
compliance with the provisions of this Agreement. In the event that such
protective order or other remedy is not obtained, or that the Company waives
compliance with the provisions of this Agreement, Intrepid covenants to furnish
only that portion of the Confidential Information which it is legally

                                        2

<PAGE>

required to disclose and will exercise its reasonable best efforts to obtain
reliable assurance that confidential treatment will be accorded the Confidential
Information.

         5.       Injunctive Relief. The parties hereto acknowledge that a
breach by the Intrepid of any of the provisions of this Agreement would cause
irreparable damage to the Company and the Business, the extent of which may be
difficult to ascertain, and that the award of damages for such a breach may not
be adequate relief. Consequently, Intrepid hereby agrees that the Company shall
be entitled to injunctive relief to compel the specific performance of the
covenants set forth in this Agreement. Such a remedy shall be cumulative, not
exclusive, and shall be in addition to any other remedy available to the Company
at law or equity, including, but not limited to, the right of the Company to
obtain its attorneys' fees and other costs in enforcing this Agreement.

         6.       Reasonableness of Provisions. In the event that any provision
of this Agreement is determined by any court of competent jurisdiction to be
unenforceable by reason of it being extended over too great a period of time or
too large a geographic area or range of activities, it should be interpreted to
extend only over the maximum period of time, geographic area, or range of
activities as to which it may be enforceable.

         7.       Remittance of Profits. Intrepid will promptly remit to the
Company the amount of any profits which may be received by it or by any other
person, firm, or corporation as a result of any violation of this Agreement, but
this remedy shall not be the exclusive remedy of the Company.

         8.       Disclosure to Future Entities. Intrepid agrees that the
Company may disclose the terms of this Agreement to any future affiliates,
owners or business associates of Intrepid.

         9.       Representations and Warranties of Intrepid. Intrepid
represents and warrants to the Company that:

                  A. Intrepid is free to enter into this Agreement and that it
         has no commitment, understanding, or arrangement to or with any party
         which restrains or is in conflict with its obligations under this
         Agreement; and

                  B. Intrepid fully understands its obligations under this
         Agreement, and Intrepid's experience and capabilities are such that the
         obligations of this Agreement will not prevent it from conducting its
         business.

10.      Miscellaneous.

                  A. Waiver of Breach. The waiver by any party to this Agreement
         of a breach of any provision of this Agreement shall not operate or be
         construed as a waiver of any subsequent breach by any party to this
         Agreement.

                  B. Binding Effect: Assignment. This Agreement shall be binding
         upon and shall inure to the benefit of the parties to this Agreement
         and their respective heirs,

                                       3
<PAGE>

         personal representatives, successors, and permitted assigns.

                  C. Amendments. No amendment or variation of the terms and
         conditions of this Agreement shall be valid unless the same is in
         writing and signed by all the parties to this Agreement.

                  D. Notices. All notices required to be given pursuant to this
         Agreement shall be deemed given when personally delivered or
         seventy-two (72) hours after mailing by first class mail to the
         addresses set forth above or to such other address as a party may
         provide to the other parties by written notice.

                  E. Headings. The section headings contained in this Agreement
         are for convenience only and shall not in any way affect the
         interpretation or enforceability of any provision of this Agreement.

                  F. Severability. Subject to Section 6 of this Agreement, in
         case any one or more of the provisions contained in this Agreement
         shall for any reason be held invalid, illegal or unenforceable in any
         respect, such invalidity, illegality or unenforceability shall not
         affect any other provision of this Agreement, and this Agreement
         (unless it otherwise fails of its essential purposes) shall be
         construed as if such invalid, illegal or unenforceable provision had
         never been a part of this Agreement.

                  G. Governing Law. This Agreement shall be construed and
         enforced pursuant to the laws of the State of Ohio, without giving
         effect to the principles of conflicts of laws thereof.

                  H. Continuation of Obligations. Intrepid's obligations under
         this Agreement and the Buyer and Company's rights with respect thereto
         will survive any termination of this Agreement.

                  I. Cost of Litigation. The parties agree that the prevailing
         party in any action or litigation brought with respect to or to enforce
         any right or remedy under this Agreement shall be entitled to recover
         from the other party or parties reasonable costs and expenses incurred
         by the prevailing party in connection with such action or litigation,
         including, without limitation, reasonable attorney's fees and costs.
