     A. Gros-ite Engineered Components Division of TOMZ, Inc., TOMZ Corporation,
Gros-ite Industries, Inc. and EDAC Technologies Corporation entered into an

     B. Matulaniec has agreed to guarantee Buyer's obligations under the
Purchase Agreement pursuant to this Agreement.

     In order to secure the payment and performance by the Buyer of its
obligations under the Purchase Agreement and in consideration of the foregoing
premises and the mutual agreements, representations, warranties and covenants
contained herein,

                                    AGREEMENT

     1. Nonrecourse Guaranty. Matulaniec hereby guarantees to the Secured Party
as of the date of the Agreement the payment and performance of the obligations
of Buyer under the Purchase Agreement; PROVIDED HOWEVER, THAT MATULANIEC'S
GUARANTY SHALL BE NONRECOURSE TO MATULANIEC AND THE SECURED PARTY'S RIGHTS
AGAINST MATULANIEC SHALL BE SOLELY LIMITED TO THE COLLATERAL PLEDGED PURSUANT TO
THIS AGREEMENT and shall be subject to the terms and conditions of this
Agreement. Matulaniec's guaranty shall terminate upon the termination of this
Agreement as set forth below.

     2. Collateral. Matulaniec hereby pledges to the Secured Party the following
publicly traded securities owned by Matulaniec and registered in his or his
nominee's name:

          (a)  $100,000 Conn. St. G.O. Tax Exempt Bond

          (b)  5,000 shs. Cooper Tire & Rubber

          (c)  1,370 shs. Dime Bank

          (d)  20,000 shs. First Australian

          (e)  5,700 shs. Hercules Trust Pfd.

which securities, as of the date hereof, have a value of not less than Four
Hundred Thousand and 00/100 Dollars ($400,000.00) ("Pledged Stock"). The Pledged

respect to the Pledged Stock reasonably necessary to perfect the Secured Party's
security interest in the Pledged Stock.

     3. Covenant of Matulaniec. If at any time the aggregate market value of the
Pledge Stock is less than $360,000, Matulaniec shall, within three (3) days of
determination by Secured Party of such shortfall, pledge additional publicly
traded securities to the Pledged Stock to eliminate such shortfall. In the event
that Secured Party exercises its rights hereunder at a time when the Pledge
Stock is less than $400,000 in value, but prior to the time that Matulaniec is
obligated to pledge additional publicly traded securities, Matulaniec personally
agrees to make up the difference between the value of the Pledge Stock and
$400,000.

     4. Delivery of Pledge Stock. Concurrent with his execution of this
Agreement, Matulaniec has caused to be delivered to an account established at
Tucker Anthony Incorporated in Hartford, Connecticut in the name of EDAC
Technologies Corporation the Pledge Stock.

     5. Covenant of Secured Party. If at any time the aggregate market value of
the Pledge Stock is greater than $440,000, Secured Party shall, within three (3)
days of determination by Matulaniec of such windfall, return such part of the
Pledged Stock to eliminate the windfall.

     6. Termination. In the absence of a default as described in the Purchase
Agreement, the escrow shall terminate upon the Escrow Agent's earlier receipt of
notice from Secured Party that the obligations of Buyer under the Purchase
Agreement have been satisfied, which notice shall be promptly given to the
Escrow Agent by Secured Party upon such satisfaction of the obligations of Buyer
under the Purchase Agreement.

     7. Representations. Matulaniec warrants and represents that he is the
beneficial owner of each share of the Pledged Stock and has the right to pledge,
grant a security interest in or otherwise transfer the Pledged Stock.

     8. Responsibility of Secured Party. Matulaniec hereby acknowledges and
agrees that:

          (a)  Preservation of Collateral. The Secured Party shall have no duty
               as to the preservation or protection of the Pledged Stock nor any
               duty to preserve any of the rights pertaining to the Pledged
               Stock.

          (b)  Changes Effecting the Collateral. Matulaniec has made
               arrangements to keep informed of changes or potential changes of
               the circumstances that affect or may affect the Pledged Stock and
               the Secured Party shall have no responsibility or liability for
               informing the Matulaniec of any such changes or potential changes
               or for taking any action or omitting to take any action with
               respect to the changes or potential changes.

     9. Default. An event of default ("Event of Default") shall be deemed to
have occurred under the Purchase Agreement in the event Buyer shall fail to make
any payment due thereunder and, following sixty (60) days written notice thereof
by Secured Party to Buyer, TOMZ Corporation and Matulaniec, Buyer and/or TOMZ
Corporation shall fail to cure said default.

Default, Secured Party shall have the following rights and remedies:

               register the Pledged Stock or any part thereof into its or its
               nominee's name with or without any indication the Pledged Stock
               is the subject matter of the security interest granted by this
               Pledge Agreement.

          (b)  Exercise of Rights. The Secured Party may exercise all rights
               with respect to the Pledged Stock as if it were the absolute

               dividends payable with respect to any part of the Pledged Stock

               additions or substitutions therefore, or any part thereof, at
               public or private sale, in one or more sales or lots, for cash or
               on credit or for future delivery, without the assumption of any
               credit risk, and for such price or prices as the Secured Party
               may determine. Unless the Pledged Stock threatens to decline
               speedily in value, the Secured Party will give Matulaniec
               reasonable notice of the time and place of any public sale
               thereof, or of the time at which any private sale or other
               intended disposition is to be made. Any sale of the Pledged Stock
               conducted in conformity with reasonable commercial practices of
               banks, insurance companies or other financial institutions
               disposing of property similar to the Pledged Stock shall be
               deemed to be commercially reasonable. Written notice of the
               intended sale or disposition of the Pledged Stock shall be mailed
               to Matulaniec at least ten (10) days prior to the time of such
               sale or disposition. Any other requirement of notice, demand or
               advertisement for sale is, to the extent permitted by law,
               waived. Unless prohibited by applicable law, the Secured Party
               may bid for and purchase all or any part of the Pledged Stock.
               The Secured Party shall have the right to execute any document or
               form, in its name or the name of Matulaniec, which may be
               necessary or desirable in connection with such sale or
               disposition.

          (e)  Commercial Code Remedies. The Secured Party may exercise any one
               or more of the rights and remedies given a secured party under
               the Uniform Commercial Code as enacted in the State of
               Connecticut.

     11. Matulaniec's Rights and Remedies. Matulaniec shall have the right at
any time and from time to time during the term of this Agreement to substitute
cash in the amount of Four Hundred Thousand Dollars ($400,000) for the Pledged
Stock. Upon delivery of such cash to Secured Party, Secured Party shall
immediately take all steps necessary to have the Pledged Stock immediately
