banking corporation, as trustee (the "Guarantee Trustee"), for the benefit of
the Holders from time to time of the Preferred Securities (as defined herein) of
Easy Gardener Products Trust I, a Delaware statutory trust, the former name of
which was U.S. Home & Garden Trust I (the "Trust").

                  WHEREAS, pursuant to an Amended and Restated Trust Agreement,
dated as of April 17, 1998 (the "First Amended Trust Agreement"), among U.S.
Home & Garden Inc. (the "Original Guarantor" or "USHG"), as Depositor,
Wilmington Trust Company as Property Trustee, Wilmington Trust Company, as
Delaware Trustee, the administrative trustees named in the First Amended Trust
Agreement and the Holders from time to time of undivided beneficial interests in

Amount (as defined in the First Amended Trust Agreement) of its 9.40% Cumulative
Trust Preferred Securities, Liquidation Amount $25 per trust preferred security
(the "Preferred Securities");

                  WHEREAS, the Preferred Securities were issued by the Trust and
the proceeds thereof, together with the proceeds from the issuance of the
Trust's common securities were used to purchase the USHG Trust Debentures (as
defined in the Amended and Restated Junior Subordinated Indenture) of the
Original Guarantor which was deposited with Wilmington Trust Company, as
Property Trustee under the First Amended Trust Agreement, as trust assets;

                  WHEREAS, as an incentive for the Holders to purchase the
Preferred Securities, the Original Guarantor entered into a Guarantee Agreement
dated as of April 17, 1998 (the "Initial Guarantee Agreement") pursuant to which
the Original Guarantor irrevocably and unconditionally agreed, to the extent set
forth therein, to pay to the Holders of the Preferred Securities the Guarantee
Payments (as defined herein) and to make certain other payments on the terms and
conditions set forth therein; and

                  WHEREAS, pursuant to an Asset Purchase Agreement (the "Asset
Purchase Agreement"), dated December 11, 2002, as amended July 31, 2003 and as
may be further amended from time to time in

Inc., a Delaware corporation and wholly-owned subsidiary of Original Guarantor
("EGI"), Ampro Industries, Inc., a Michigan corporation and wholly-owned

substantially all of the assets and properties of the Sellers and assume and
become responsible for, among other things, all of the Original Guarantor's
obligations under the Original Indenture (as defined in the Amended and Restated
Junior Subordinated Indenture) and the Initial Guarantee Agreement; and

                  WHEREAS, as the assets and properties of the Sellers to be
sold to the Guarantor pursuant to the term of the Asset Purchase Agreement
comprise, indirectly, on a consolidated basis, substantially all of the
properties and assets of the Original Guarantor; and

                  WHEREAS, pursuant to a special meeting of the Holders of the
Trust, the requisite Holders voted in favor of an amendment to, among other
documents, the Initial Guarantee Agreement to indicate that the sale by the
Sellers of substantially all of their assets and properties to the Guarantor be
deemed a transfer by the Original Guarantor of the Original Guarantor's
properties and assets substantially as an entirety under Sections 7.1 and 7.2 of
the Initial Guarantee Agreement; and

                  WHEREAS, upon the closing of the transactions contemplated by
the Asset Purchase Agreement and the assumption by the Guarantor of the
obligations of Original Guarantor, the Original Guarantor will be discharged
from all its obligations under the Original Indenture and the Initial Guarantee
Agreement, including without limitation, the obligation to pay to the Holders of
the Preferred Securities pursuant to the Initial Guarantee Agreement; and

                  WHEREAS, the parties hereto are amending and restating the
Initial Guarantee Agreement to reflect the Guarantor as the new obligor with
respect to the Guarantee.

               POWERS, DUTIES AND RIGHTS OF THE GUARANTEE TRUSTEE

SECTION 3.1       Powers and Duties of the Guarantee Trustee.

                           (a)      This Guarantee shall be held by the
Guarantee Trustee for the benefit of the Holders, and the Guarantee Trustee
shall not transfer this Guarantee to any Person except to a Holder exercising
his or her rights pursuant to Section 5.4(iv) or to a Successor Guarantee
Trustee on acceptance by such Successor Guarantee Trustee of its appointment to
act as Successor Guarantee Trustee. The right, title and interest of the
Guarantee Trustee shall automatically vest in any Successor Guarantee Trustee,
upon acceptance by such Successor Guarantee Trustee of its appointment
hereunder, and such vesting and cessation of title shall be effective whether or
not conveyancing documents have been executed and delivered pursuant to the
appointment of such Successor Guarantee Trustee.

                           (b)      If an Event of Default has occurred and is
continuing, the Guarantee Trustee shall enforce this Guarantee for the benefit
of the Holders.

                           (c)      The Guarantee Trustee, before the occurrence
of any Event of Default and after the curing of all Events of Default that may
have occurred, shall undertake to perform only such duties as are specifically
set forth in this Guarantee Agreement, and no implied covenant shall be read
into this Guarantee Agreement against the Guarantee Trustee. In case an Event of
Default has occurred (that has not been cured or waived pursuant to Section
2.6), the Guarantee Trustee shall exercise such of the rights and powers vested
in it by this Guarantee Agreement, and use the same degree of care and skill in
its exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

                           (d)      No provision of this Guarantee Agreement
shall be construed to relieve the Guarantee Trustee from liability for its own
negligent action, its own negligent failure to act or its own willful
misconduct, except that:

                                       9
<PAGE>

                           (i)      prior to the occurrence of any Event of
         Default and after the curing or waiving of all such Events of Default
         that may have occurred:

                                    (A)      The duties and obligations of the
                  Guarantee Trustee shall be determined solely by the express
                  provisions of this Guarantee Agreement, and the Guarantee
                  Trustee shall not be liable except for the performance of such
                  duties and obligations as are specifically set forth in this
                  Guarantee Agreement; and

                                    (B)      in the absence of bad faith on the
                  part of the Guarantee Trustee, the Guarantee Trustee may
                  conclusively rely, as to the truth of the statements and the
                  correctness of the opinions expressed therein, upon any
                  certificates or opinions furnished to the Guarantee Trustee
                  and conforming to the requirements of this Guarantee
                  Agreement; but in the case of any such certificates or
                  opinions that by any provision hereof or of the Trust
                  Indenture Act are specifically required to be furnished to the
                  Guarantee Trustee, the Guarantee Trustee shall be under a duty
                  to examine the same to determine whether or not they conform
                  to the requirements of this Guarantee Agreement;

                           (ii)     The Guarantee Trustee shall not be liable
         for any error of judgment made in good faith by a Responsible Officer
         of the Guarantee Trustee, unless it shall be proved that the Guarantee
         Trustee was negligent in ascertaining the pertinent facts upon which
         such judgment was made;

                           (iii)    the Guarantee Trustee shall not be liable
         with respect to any action taken or omitted to be taken by it in good
         faith in accordance with the direction of the Holders of not less than
         a Majority in Liquidation Amount of the Preferred Securities relating
         to the time, method and place of conducting any proceeding for any
         remedy available to the Guarantee Trustee, or exercising any trust or
         power conferred upon the Guarantee Trustee under this Guarantee
         Agreement; and

                           (iv)     no provision of this Guarantee Agreement
         shall require the Guarantee Trustee to expend or risk its own funds or
         otherwise incur personal financial liability in the performance of any
         of its duties or in the

                                       10
<PAGE>

         exercise of any of its rights or powers, if the Guarantee Trustee shall
         have reasonable grounds for believing that the repayment of such funds
         or liability is not reasonably assured to it under the terms of this
         Guarantee Agreement or adequate indemnity against such risk or
         liability is not reasonably assured to it.

                           (a)      Subject to the provisions of Section 3.1:

         this Guarantee Agreement, the Guarantee Trustee shall deem it desirable
         that a matter be proved or established before taking, suffering or
         omitting to take any action hereunder, the Guarantee Trustee (unless
         other evidence is herein specifically prescribed) may, in the absence
         of bad faith on its part, request and rely upon an Officers'
         Certificate which, upon receipt of such request from the Guarantee
         Trustee, shall be promptly delivered by the Guarantor.

                                    (iv)     The Guarantee Trustee may consult
         with legal counsel, and the written advice or opinion of such legal

         under no obligation to exercise any of the rights or powers vested in
         it by this Guarantee Agreement at the request or direction of any
         Holder, unless such Holder shall have provided to the Guarantee Trustee
         such adequate security and indemnity as would satisfy a reasonable
         person in the position of the Guarantee Trustee, against the costs,
         expenses (including attorneys' fees and expenses) and liabilities that
         might be incurred by it in complying with such request or direction,
         including such reasonable advances as may be requested by the Guarantee
         Trustee; provided that, nothing contained in this Section 3.2(a)(v)

         other evidence of indebtedness or other paper or document, but the
         Guarantee Trustee, in its discretion, may make such further inquiry or
         investigation into such facts or matters as it may see fit.

                                    (vii)    The Guarantee Trustee may execute

         negligence on the part of any such agent or attorney appointed with due
         care by it hereunder.

                                    (viii)   Whenever in the administration of

right, power, duty or obligation conferred or imposed on it in any jurisdiction
in which it shall be illegal, or in which the Guarantee Trustee shall be
unqualified or incompetent in accordance with applicable law, to perform any
such act or acts or to exercise any such right, power, duty or obligation. No
permissive power or authority available to the Guarantee Trustee shall be
construed to be a duty to act in accordance with such power and authority.

and to hold it harmless against, any loss, liability or expense incurred without

                           (a)      the release or waiver, by operation of law
or otherwise, of the performance or observance by the Trust of any express or
implied agreement, covenant, term or condition relating to the Preferred
Securities to be performed or observed by the Trust;

                           (b)      the extension of time for the payment by the

as provided in the Indenture), Redemption Price, Liquidation Distribution or any
other sums payable under the terms of the Preferred Securities or the extension
of time for the performance of any other obligation under, arising out of, or in
connection with, the Preferred Securities;

                           (c)      any failure, omission, delay or lack of
diligence on the part of the Holders to enforce, assert or exercise any right,
privilege, power or remedy conferred on the Holders pursuant to the terms of the
Preferred Securities, or any action on the part of the Trust granting indulgence
or extension of any kind;

                           (d)      the voluntary or involuntary liquidation,
dissolution, sale of any collateral, receivership, insolvency, bankruptcy,
assignment for the benefit of creditors, reorganization, arrangement,
composition or readjustment of debt of, or other similar proceedings affecting,
the Trust or any of the assets of the Trust;

                           (e)      any invalidity of, or defect or deficiency
in, the Preferred Securities;

                           (f)      the settlement or compromise of any
obligation guaranteed hereby or hereby incurred; or

                           (g)      any other circumstance whatsoever that might
otherwise constitute a legal or equitable discharge or defense of a guarantor,
it being the intent of this Section 5.3 that the obligations of the Guarantor
hereunder shall be absolute and unconditional under any and all circumstances.

There shall be no obligation of the Holders to give notice to, or obtain the
consent of, the Guarantor with respect to the happening of any of the foregoing.

SECTION 5.4       Rights of Holders.

                  The Guarantor expressly acknowledges that: (i) this Guarantee
will be deposited with the Guarantee Trustee to be held for the benefit of the
Holders; (ii) the Guarantee Trustee has the right to enforce this Guarantee on
behalf of the Holders; (iii) the Holders of a Majority in Liquidation Amount of
the Preferred Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee in
respect of this Guarantee Agreement or exercising any trust or power conferred
upon the Guarantee Trustee under this Guarantee Agreement; and (iv) any

                                       16
<PAGE>

Holder may institute a legal proceeding directly against the Guarantor to
enforce its rights under this Guarantee Agreement, without first instituting a
legal proceeding against the Guarantee Trustee, the Trust or any other Person.

SECTION 5.5       Guarantee of Payment.

                  This Guarantee creates a guarantee of payment and not of
collection. This Guarantee will not be discharged except by payment of the
Guarantee Payments in full (without duplication of amounts theretofore paid by
the Trust) or upon distribution of Debentures to Holders as provided in the
Trust Agreement.

SECTION 5.6       Subrogation.

                  The Guarantor shall be subrogated to all (if any) rights of
the Holders against the Trust in respect of any amounts paid to the Holders by
the Guarantor under this Guarantee Agreement and shall have the right to waive
payment by the Trust pursuant to section 5.1; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of
law) be entitled to enforce or exercise any rights which it may acquire by way
of subrogation or any indemnity, reimbursement or other agreement, in all cases
as a result of payment under this Guarantee, if, at the time of any such
payment, any amounts are due and unpaid under this Guarantee. If any amount
shall be paid to the Guarantor in violation of the preceding sentence, the
Guarantor agrees to hold such amount in trust for the Holders and to pay over
such amount to the Holders.

SECTION 5.7       Independent Obligations

                  The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Trust with respect to the Preferred
Securities and that the Guarantor shall be liable as principal and as debtor
hereunder to make Guarantee Payments pursuant to the terms of this Guarantee
Agreement notwithstanding the occurrence of any event referred to in subsections
(a) through (g), inclusive, of Section 5.3 hereof.

SECTION 6.1       Subordination.

                  The obligations of the Guarantor under this Guarantee will
constitute unsecured obligations of the Guarantor and will rank subordinate and
junior in right of payment to all Senior Debt and Subordinated Debt (as defined
in the Indenture) in the same manner as Debentures (as defined in the Trust
Agreement).

SECTION 6.2       Pari Passu Guarantees.

                  The obligations of the Guarantor under this Guarantee shall
rank pari passu with the obligations of the Guarantor under all Other
Guarantees.

              CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE

SECTION 7.1       Guarantor May Consolidate, Etc., Only on Certain Terms.

                  The Guarantor shall not consolidate with or merge into any
other Person or convey, transfer or lease its properties and assets
substantially as an entirety to any Person, and no Person shall consolidate with
or merge into the Guarantor or convey, transfer or lease its properties and
assets substantially as an entirety to the Guarantor, unless:

                  (1) in case the Guarantor shall consolidate with or merge into
another Person or convey, transfer or lease its properties and assets
substantially as an entirety to any Person, the Person formed by such
consolidation or into which the Guarantor is merged or the Person which acquires
by conveyance or transfer, or which leases, the properties and assets of the
Guarantor substantially as an entirety shall be a corporation, partnership or
trust organized and existing under the laws of the United States of America or
any State or the District of Columbia, and shall expressly assume the
Guarantor's obligations under this Guarantee;

                  (2) immediately after giving effect thereto, no Event of
Default, and no event which, after notice or lapse of time, or both, would
become an Event of Default, shall have happened and be continuing;

                                       18
<PAGE>

                  (3) such consolidation, merger, conveyance, transfer or lease
is permitted under the Trust Agreement and the Indenture and does not give rise
to any breach or violation of the Trust Agreement or the Indenture; and

                  (4) the Guarantor has delivered to the Guarantee Trustee an
Officers' Certificate and an Opinion of Counsel, each stating that such
consolidation, merger, conveyance, transfer or lease and assumption of the
Guarantor's obligations under this Guarantee Agreement comply with this Article
and that all conditions precedent herein provided for relating to such
transaction have been complied with; and the Guarantee Trustee, subject to
Section 3.1 hereof, may rely upon such Officers' Certificate and Opinion of
Counsel as conclusive evidence that such transaction complies with this Section
7.1.

                  (5) Notwithstanding anything in this Guarantee or the Initial
Guarantee Agreement to the contrary, the sale (the "Sale") by USHG's
wholly-owned subsidiaries, EGI and Ampro, of their assets substantially as an
entirety to EGP, as set forth in the Asset Purchase Agreement, shall be deemed
to be a transfer by USHG of USHG's properties and assets substantially as an
entirety under Section 7.1 and under Section 7.2 of this Guarantee and the
Initial Guarantee Agreement.

SECTION 7.2       Successor Guarantor Substituted.

                  Upon any consolidation or merger by the Guarantor with or into
any other Person, or any conveyance, transfer or lease by the Guarantor of its
properties and assets substantially as an entirety to any Person in accordance
with Section 7.1, the successor Person formed by such consolidation or into
which the Guarantor is merged or to which such conveyance, transfer or lease is
made shall succeed to, and be substituted for, and may exercise every right and
power of, the Guarantor under this Guarantee Agreement with the same effect as
if such successor Person had been named as the Guarantor herein; and in the
event of any such conveyance, transfer or lease the Guarantor shall be
discharged from all obligations and covenants under this Guarantee Agreement.

Redemption Price of all Preferred Securities, (ii) the distribution of
Debentures to the Holders in exchange for all of the Preferred Securities or
(iii) full payment of the amounts payable in accordance with the Trust Agreement
upon liquidation of the Trust. Notwithstanding the foregoing clauses (i) through

reinstated if it has been terminated pursuant to one of such clauses (i) through
(iii), as the case may be, if at any time any Holder must restore payment of any
sums paid with respect to Preferred Securities or this Guarantee Agreement.

of the Preferred Securities then outstanding. Except in connection with a
consolidation, merger or sale involving the Guarantor (including, without

Article VII hereof and Article VIII of the Indenture, the Guarantor shall not
assign its obligations hereunder.

SECTION 9.2       Amendments.

Preferred Securities. The provisions of Article VI of the Trust Agreement
concerning meetings of the Holders shall apply to the giving of such approval.
