     WITNESSETH

     WHEREAS, the Issuer and the Original Guarantors have previously executed
and delivered to the Trustee an indenture (the "Indenture"), dated as of April
22, 1999, providing for the issuance of an aggregate principal amount of up to
$350,000,000 of 9% Senior Subordinated Notes due 2009;

     WHEREAS, the Issuer has completed a corporate restructuring, which
included, among other things, the formation of the Guarantying Subsidiary and
the merger of Hydro Flame Corporation, an Original Guarantor under the
Indenture, with and into the Guarantying Subsidiary.

     WHEREAS, Section 11.05 of the Indenture provides that the person acquiring
the property of a Guarantor in a merger must assume all of the obligations of
the Guarantor under the Indenture pursuant to a Supplemental Indenture; and

     WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture.

     NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the parties
hereto mutually covenant and agree for the equal and ratable benefit of the
Holders of the Securities as follows:

     1.   Agreement to Guarantee. The Guaranteeing Subsidiary hereby agree as
          follows:

     (a)  Along with all Guarantors named in the Indenture, to unconditionally
          guarantee (each such guarantee to be referred to herein as a "Note
          Guarantee") to each Holder of a Note authenticated and delivered by
          the Trustee and to the Trustee and its successors and


<PAGE>   2

          assigns, irrespective of the validity and enforceability of this
          Supplemental Indenture, the Notes or the obligations of the Issuer
          hereunder or thereunder, that: (i) the principal of and interest on
          the Notes will be promptly paid in full when due, whether at maturity,
          by acceleration, redemption or otherwise, and interest on the overdue
          principal of and interest on the Notes, if any, if lawful, and all
          other obligations of the Issuer to the Holders or the Trustee
          hereunder or thereunder will be promptly paid in full or performed,
          all in accordance with the terms hereof and thereof; and (ii) in case
          of any extension of time of payment or renewal of any Notes or any of
          such other obligations, that same will be promptly paid in full when
          due or performed in accordance with the terms of the extension or
          renewal, whether at stated maturity, by acceleration or otherwise.
          Failing payment when due of any amount so guaranteed or any
          performance so guaranteed for whatever reason, the Guaranteeing
          Subsidiary shall be jointly and severally obligated to pay the same
          immediately. The Guaranteeing Subsidiary agrees that this is a
          guarantee of payment and not a guarantee of collection.

     (b)  The Guaranteeing Subsidiary hereby agrees that its obligations
          hereunder shall be unconditional, irrespective of the validity,
          regularity or enforceability of the Notes or this Supplemental
          Indenture, the absence of any action to enforce the same, any waiver
          or consent by any Holder of the Notes with respect to any provisions
          hereof or thereof, the recovery of any judgment against the Issuer,
          any action to enforce the same or any other circumstance which might
          otherwise constitute a legal or equitable discharge or defense of any
          other Guarantor. The Guaranteeing Subsidiary hereby waives diligence,
          presentment, demand of payment, filing of claims with a court in the
          event of insolvency or bankruptcy of the Issuer, any right to require
          a proceeding first against the Issuer, protest, notice and all demands
          whatsoever and covenants that its Note Guarantee shall not be
          discharged except by complete performance of the obligations contained
          in the Notes, the Indenture and this Note Guarantee.

     (c)  If any Holder or the Trustee is required by any court or otherwise to
          return to the Issuer, to any Guarantor, or any custodian, trustee,
          liquidator or other similar official acting in relation to either the
          Issuer or to any Guarantor, any amount paid by either to the Trustee
          or such Holder, the Note Guarantee, to the extent theretofore
          discharged, shall be reinstated in full force and effect.

     (d)  The Guaranteeing Subsidiary agrees that it shall not be entitled to
          any right of subrogation in relation to the Holders in respect of any
          Note Guarantee until payment in full of all obligations guaranteed
          under this Supplemental Indenture. The Guaranteeing Subsidiary further
          agrees that, as between it, on the one hand, and the Holders and the
          Trustee, on the other hand, (x) the maturity of the obligations
          guaranteed hereby may be accelerated as provided in Article 6 of the
          Indenture for the purposes of this Note Guarantee, notwithstanding any
          stay, injunction or other prohibition preventing such acceleration in


                                       2
<PAGE>   3

          respect of the obligations guaranteed hereby, and (y) in the event of
          any declaration of acceleration of such obligations as provided in
          Article 6 of the Indenture, such obligations (whether or not due and
          payable) shall forthwith become due and payable by the Guaranteeing
          Subsidiary for the purpose of this Note Guarantee. The Guaranteeing
          Subsidiary shall have the right to seek contribution from any
          non-paying Guarantor so long as the exercise of such right does not
          impair the rights of the Holders under this Note Guarantee.

     2. Incorporation of Terms of Indenture. The obligations of the Guaranteeing
Subsidiary under the Note Guarantees shall be governed in all respects by the
terms of the Indenture and shall constitute a Guarantee thereunder. Each of the
parties hereto shall be bound by the terms of the Indenture as they relate to
the Note Guarantees.

     3. No Recourse Against Others. No stockholder, officer, director, employee
or incorporator, past, present or future, or the Guaranteeing Subsidiary, as
such, shall have any personal liability under this Note Guarantee by reason of
his, her or its status as such stockholder, officer, director, employee or
incorporator.

     4. NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL
GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE BUT WITHOUT GIVING
EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE
APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

     5. Counterparts. The parties may sign any number of copies of this
Supplemental Indenture. Each signed copy shall be an original, but all of them
together represent the same agreement.

     6. Effect of Headings. The Section headings herein are for convenience only
and shall not affect the construction hereof.

     7. Disclaimer by Trustee. The Trustee makes no representation as to the
validity of this Supplemental Indenture or the proper authorization or due
execution of this Supplemental Indenture by the Issuer, the Original Guarantors
or the Guaranteeing Subsidiary.
