                                                                  EXECUTION COPY


                      FIFTH AMENDMENT TO GUARANTY AGREEMENT

        This FIFTH AMENDMENT TO GUARANTY AGREEMENT (this "Amendment"), dated as
of September 20, 2002, is made and entered into by and between CARAUSTAR
INDUSTRIES, INC., a North Carolina corporation (the "Guarantor"), and SUNTRUST
BANK, a Georgia banking corporation, formerly known as SunTrust Bank, Atlanta
(the "Lender").

                              W I T N E S S E T H:

        WHEREAS, the Guarantor executed that certain Guaranty Agreement, dated
as of July 30, 1999, in favor of the Lender, as amended by that certain First
Amendment to Guaranty Agreement dated as of September 29, 2000, that certain
Second Amendment and Waiver to Guaranty Agreement dated as of March 12, 2001,
that certain Third Amendment to Guaranty Agreement dated as of April 9, 2001 and
that certain Fourth Amendment and Waiver to Guaranty Agreement dated as of
January 18, 2002 (as so amended, the "Guaranty Agreement"), pursuant to which
the Guarantor guaranteed 50% of the obligations of Premier Boxboard Limited LLC,
a Delaware limited liability corporation (the "Borrower"), under a certain
Amended and Restated Revolving Credit Agreement dated as of December 18, 2000,
as amended by that certain First Amendment to Revolving Credit Agreement, dated
as of March 12, 2001 (as the same may be further amended, restated, supplemented
or otherwise modified from time to time, the "Credit Agreement"; capitalized
terms used herein and not otherwise defined shall have the meanings assigned to
such terms in the Credit Agreement);

        WHEREAS, the Guarantor previously executed in favor of the Lender that
certain Fifth Amendment to Guaranty Agreement dated as of June 6, 2002 (the
"June 2002 Guaranty Amendment");

        WHEREAS, notwithstanding the fact that the June 2002 Guaranty Amendment
was executed by the parties and deemed closed as of June 6, 2002, the June 2002
Guaranty Amendment contained certain conditions precedent to effectiveness,
which conditions have not been satisfied, and, accordingly, has not become
effective except to the extent provided therein;

        WHEREAS, the Guarantor has requested that the Lender amend the Guaranty
Agreement in the manner set forth below, and the Lender and Guarantor intend
that this Amendment shall amend, restate and replace the June 2002 Guaranty
Amendment such that the June 2002 Guaranty Amendment shall have no further force
or effect, and the Lender is willing to do so subject to the terms and
conditions contained herein;

        NOW, THEREFORE, in consideration of the terms and conditions contained
herein, the parties hereto, intending to be legally bound, hereby amend the
Guaranty Agreement and agree as follows:

        1.     Section 7 of the Guaranty Agreement is hereby amended by
inserting the following new Sections in the appropriate numerical order:

               SECTION 7.5 INSURANCE. Maintain with insurers of recognized
        responsibility, insurance with respect to its properties and business,
        against loss or

<PAGE>

        damage of the kinds customarily insured against by reputable companies
        in the same or similar businesses, such insurance to be of such types
        and in such amounts reasonably consistent with those amounts which are
        customary for such companies under similar circumstances; provided,
        however, that in any event Guarantor shall use its best efforts to
        maintain, or cause to be maintained, insurance in amounts and with
        coverages not materially less favorable to Guarantor as in effect on the
        date of this Agreement, provided that within ten (10) business days
        after the occurrence of the Second Amendment Effective Date, the
        Caraustar Administrative Agent shall be named as loss payee, as its
        interest may appear, and/or additional insured with respect to any such
        insurance providing coverage in respect of any Collateral, and each
        provider of any such insurance shall agree, by endorsement upon the
        policy or policies issued by it or by independent instruments furnished
        to the Caraustar Administrative Agent, that it will give the Caraustar
        Administrative Agent thirty (30) days prior written notice before any
        such policy or policies shall be altered or canceled.

               SECTION 7.6   VISITATION, INSPECTION, ETC.

               (a)    At any time during which no Default or Event of Default
        shall have occurred and be continuing, Guarantor shall permit a
        representative of Lender to visit and inspect any of the property of
        Guarantor, to examine its books of account, records, reports and other
        papers, to make extracts therefrom, and to discuss its affairs,
        finances, and accounts with its officers and employees, all at such
        reasonable times, but (unless a Default or Event of Default shall occur)
        not more often than twice during each calendar year, as may be
        reasonably requested.

               (b) At any time during which a Default or Event of Default shall
        have occurred and be continuing, Guarantor shall permit a representative
        of Lender to visit and inspect any of the property of Guarantor, to
        examine its books of accounts, records, reports and other papers, to
        make copies and extracts therefrom (so long as, in the reasonable
        opinion of Guarantor, the information to be copied does not constitute
        proprietary information of its business operations), and to discuss its
        affairs, finances and accounts with its officers and employees, all at
        such reasonable times and as often as may be reasonably requested;
        provided that, after the occurrence and during the continuance of an
        Event of Default, any such action shall be at the expense of the
        Guarantor.

               (c) After the occurrence of the Second Amendment Effective Date,
        Guarantor agrees that the Lender, and its representatives, may conduct
        an annual audit of the Collateral, at the expense of the Guarantor.

               SECTION 7.7 PLEDGED ASSETS. Guarantor will (i) cause all of its
        Property that constitutes (or pursuant to the terms of the Security
        Agreement is intended to constitute) Collateral to be subject at all

        Administrative Agent, for the benefit of the secured parties referred to
        in the Collateral Documents, to secure the Obligations pursuant to the
        terms and conditions of the Collateral Documents,

        Caraustar Credit Agreement and the Security Agreement, and (ii) deliver,
        or, in the case of agreements or other documents that require the
        consent of a non-Affiliate of the Guarantor, use commercially reasonable
        efforts to deliver, such other documentation as the Caraustar
        Administrative Agent may reasonably request in connection with the
        foregoing, including, without limitation, appropriate UCC-1 financing
        statements, landlord's waivers (subject to Section 8.14 of the Caraustar
        Credit Agreement), certified resolutions and other organizational and
        authorizing documents of such Person, favorable opinions of counsel to
        such Person (which shall cover, among other things, the legality,
        validity, binding effect and enforceability of the documentation
        referred to above and the perfection of the Caraustar Administrative
        Agent Liens thereunder), all in form, content and scope reasonably
        satisfactory to the Caraustar Administrative Agent.

        Agreement and the other Credit Documents or creating or perfecting or
        ensuring the priority or sufficiency or enforceability or enforcement of
        a Lien in favor of the Caraustar Administrative Agent as security for
        the Obligations upon any or all of the Collateral (whether owned prior
        to the Second Amendment Effective Date or thereafter acquired), or more
        fully perfecting or renewing any such Lien;

                      (ii)   To the extent requested by the Caraustar
        Administrative Agent, at its expense, if the exercise by the Caraustar
        Administrative Agent or Lender of any power, right, privilege or remedy
