                                                                  EXECUTION COPY


                                            GUARANTEE AGREEMENT dated as of May
                                    7, 1999, among AMERICAN MEDIA, INC.
                                    ("HOLDINGS"), a Delaware corporation, each
                                    of the subsidiaries listed on Schedule I
                                    hereto (each such subsidiary individually,
                                    a "SUBSIDIARY" and, collectively, the
                                    "SUBSIDIARIES"; and each such Subsidiary
                                    and Holdings, individually, a "GUARANTOR"
                                    and, collectively, the "GUARANTORS") and
                                    THE CHASE MANHATTAN BANK, a New York
                                    banking corporation, as collateral agent
                                    (the "COLLATERAL AGENT") for the Secured
                                    Parties (as defined in the Security
                                    Agreement).

         Reference is made to the Credit Agreement dated as of May 7, 1999 (as
amended, supplemented or otherwise modified from time to time, the "CREDIT
AGREEMENT"), among American Media Operations, Inc., a Delaware corporation (the
"BORROWER"), Holdings, the lenders from time to time party thereto (the
"LENDERS") and The Chase Manhattan Bank, as administrative agent for the
Lenders (in such capacity, the "ADMINISTRATIVE AGENT"). Capitalized terms used
herein and not defined herein shall have the meanings assigned to such terms in
the Credit Agreement.

         The Lenders have agreed to make Loans to the Borrower, and the Issuing
Bank has agreed to issue Letters of Credit for the account of the Borrower,
pursuant to, and upon the terms and subject to the conditions specified in, the
Credit Agreement. Each of the Subsidiaries is a direct or indirect subsidiary
of the Borrower and acknowledges that it will derive substantial benefit from
the making of the Loans by the Lenders and the issuance of Letters of Credit by
the Issuing Bank. The obligations of the Lenders to make Loans and of the
Issuing Bank to issue Letters of Credit are conditioned on, among other things,
the execution and delivery by the Guarantors of a Guarantee Agreement in the
form hereof. As consideration therefor and in order to induce the Lenders to
make Loans and the Issuing Bank to issue Letters of Credit, the Guarantors are
willing to execute this Agreement.

         Accordingly, the parties hereto agree as follows:

         SECTION 1. GUARANTEE. Each Guarantor unconditionally guarantees,
jointly with the other Guarantors and severally, as a primary obligor and not
merely as a surety, (a) the due and punctual payment of (i) the principal of
and premium, if any, and interest (including interest accruing during the
pendency of any bankruptcy, insolvency, receivership or other similar
proceeding, regardless of whether allowed or allowable in such proceeding) on
the Loans, when and as due, whether at maturity, by acceleration, upon one or
more dates set for prepayment or otherwise, (ii) each payment required to be
made by the Borrower under the Credit Agreement in respect of any Letter of
Credit, when and as due, including payments in respect of reimbursement of
disbursements, interest thereon and obligations to provide cash collateral and
(iii) all other monetary obligations, including fees, costs, expenses and
indemnities, whether primary, secondary, direct, contingent, fixed or otherwise
(including monetary obligations incurred during the pendency of any bankruptcy,
insolvency, receivership or other similar proceeding, regardless of whether
allowed or allowable in such proceeding), of the Loan Parties to the Secured
Parties under the Credit Agreement and the other Loan Documents, (b) the due
and punctual performance of all covenants, agreements, obligations and
liabilities of the Loan Parties under or pursuant to the Credit Agreement and
the other Loan Documents, (c) the due and punctual payment and performance of
all obligations of the Borrower or any other Loan Party, monetary or otherwise,
under each Hedging Agreement entered into with a counterparty that was a Lender
(or an Affiliate of a Lender) at the time such Hedging Agreement was entered
into and (d) the due and punctual payment and performance of all obligations in
respect of overdrafts and related liabilities owed to the Administrative Agent
or any of its Affiliates and arising from treasury, depositary and cash
management services in connection with any automated clearing house transfers
of funds (all the monetary and other obligations referred to in the preceding
clauses (a) through (d) being collectively called the "OBLIGATIONS"). Each
Guarantor further agrees that the Obligations may be

                                                                              2


extended or renewed, in whole or in part, without notice to or further assent
from it, and that it will remain bound upon its guarantee notwithstanding any
extension or renewal of any Obligation.

         SECTION 2. OBLIGATIONS NOT WAIVED. To the fullest extent permitted by
applicable law, each Guarantor waives presentment to, demand of payment from
and protest to the Borrower of any of the Obligations, and also waives notice
of acceptance of its guarantee and notice of protest for nonpayment. To the
fullest extent permitted by applicable law, the obligations of each Guarantor
hereunder shall not be affected by (a) the failure of the Collateral Agent or
any other Secured Party to assert any claim or demand or to enforce or exercise
any right or remedy against the Borrower or any Guarantor under the provisions
of the Credit Agreement, any other Loan Document or otherwise; (b) any
recision, waiver, amendment or modification of, or any release from any terms
or provisions of this Agreement, any other Loan Document, any Guarantee or any
other agreement, including with respect to any other Guarantor under this
Agreement or (c) the failure to perfect any security interest in, or release
of, any of the security held by or on behalf of the Collateral Agent or any
other Secured Party.

         SECTION 3. SECURITY. Each of the Guarantors authorizes the Collateral
Agent and each of the other Secured Parties to (a) take and hold security for
the payment of this Guarantee and the Obligations and exchange, enforce, waive
and release any such security, (b) apply such security and direct the order or
manner of sale thereof as they in their sole discretion may determine and (c)
release or substitute any one or more endorsees, other guarantors or other
obligors.

         SECTION 4. GUARANTEE OF PAYMENT. Each Guarantor further agrees that
its guarantee constitutes a guarantee of payment when due and not of
collection, and waives any right to require that any resort be had by the
Collateral Agent or any other Secured Party to any of the security held for
payment of the Obligations or to any balance of any deposit account or credit
on the books of the Collateral Agent or any other Secured Party in favor of the
Borrower or any other Person.

         SECTION 5. NO DISCHARGE OR DIMINISHMENT OF GUARANTEE. The obligations
of each Guarantor hereunder shall not be subject to any reduction, limitation,
impairment or termination for any reason (other than the indefeasible payment
in full in cash of the Obligations), including any claim of waiver, release,
surrender, alteration or compromise of any of the Obligations, and shall not be
subject to any defense or setoff, counterclaim, recoupment or termination
whatsoever by reason of the invalidity, illegality or unenforceability of the
Obligations or otherwise. Without limiting the generality of the foregoing, the
obligations of each Guarantor hereunder shall not be discharged or impaired or
otherwise affected by the failure of the Collateral Agent or any other Secured
Party to assert any claim or demand or to enforce any remedy under the Credit
Agreement, any other Loan Document or any other agreement, by any waiver or
modification of any provision of any thereof, by any default, failure or delay,
wilful or otherwise, in the performance of the Obligations, or the failure to
perfect any security interest in, or the release of, any of the security held
by or on behalf of the Collateral Agent or any other Secured Party, or by any
other act or omission that may or might in any manner or to any extent vary the
risk of any Guarantor or that would otherwise operate as a discharge of each
Guarantor as a matter of law or equity (other than the indefeasible payment in
full in cash of all the Obligations).

         SECTION 6. DEFENSES OF BORROWER WAIVED. To the fullest extent
permitted by applicable law, each of the Guarantors waives any defense based on
or arising out of any defense of the Borrower or the unenforceability of the
Obligations or any part thereof from any cause, or the cessation from any cause
of the liability of the Borrower, other than the final and indefeasible payment
in full in cash of the Obligations. The Collateral Agent and the other Secured
Parties may, at their election, foreclose on any security held by one or more
of them by one or more judicial or nonjudicial sales, accept an assignment of
any such security in lieu of foreclosure, compromise or adjust any part of the
Obligations, make any other accommodation with the Borrower or any other
guarantor or exercise any other right or remedy available to them against the
Borrower or any other guarantor, without affecting or impairing in any way the
liability of any Guarantor hereunder except to the extent the Obligations have
been fully, finally and indefeasibly



<PAGE>   3
                                                                              3


paid in cash. Pursuant to applicable law, each of the Guarantors waives any
defense arising out of any such election even though such election operates,
pursuant to applicable law, to impair or to extinguish any right of
reimbursement or subrogation or other right or remedy of such Guarantor against
the Borrower or any other Guarantor or guarantor, as the case may be, or any
security.

         SECTION 7. AGREEMENT TO PAY; SUBORDINATION. In furtherance of the
foregoing and not in limitation of any other right that the Collateral Agent or
any other Secured Party has at law or in equity against any Guarantor by virtue
hereof, upon the failure of the Borrower or any other Loan Party to pay any
Obligation when and as the same shall become due, whether at maturity, by
acceleration, after notice of prepayment or otherwise, each Guarantor hereby
promises to and will forthwith pay, or cause to be paid, to the Collateral
Agent or such other Secured Party as designated thereby in cash the amount of
such unpaid Obligations. Upon payment by any Guarantor of any sums to the
Collateral Agent or any Secured Party as provided above, all rights of such
Guarantor against the Borrower arising as a result thereof by way of right of
subrogation, contribution, reimbursement, indemnity or otherwise shall in all
respects be subordinate and junior in right of payment to the prior
indefeasible payment in full in cash of all the Obligations. In addition, any
indebtedness of any Loan Party now or hereafter held by any Guarantor is hereby
subordinated in right of payment to the prior payment in full of the
Obligations, PROVIDED that so long as no Default exists or is continuing, any
Loan Party may repay indebtedness of such Loan Party held by any other Loan
Party without regard to such subordination. If any amount shall erroneously be
paid to any Guarantor on account of (i) such subrogation, contribution,
reimbursement, indemnity or similar right or (ii) any such indebtedness of any
Loan Party, such amount shall be held in trust for the benefit of the Secured
Parties and shall forthwith be paid to the Collateral Agent to be credited
against the payment of the Obligations, whether matured or unmatured, in
accordance with the terms of the Loan Documents.

         SECTION 8. INFORMATION. Each of the Guarantors assumes all
responsibility for being and keeping itself informed of the Borrower's
financial condition and assets, and of all other circumstances bearing upon the
risk of nonpayment of the Obligations and the nature, scope and extent of the
risks that such Guarantor assumes and incurs hereunder, and agrees that none of
the Collateral Agent or the other Secured Parties will have any duty to advise
any of the Guarantors of information known to it or any of them regarding such
circumstances or risks.

         SECTION 9. REPRESENTATIONS AND WARRANTIES. Each of the Guarantors
represents and warrants as to itself that all representations and warranties
relating to it contained in the Credit Agreement are true and correct.

         SECTION 10. TERMINATION. The Guarantees made hereunder (a) shall
terminate when all the Obligations have been indefeasibly paid in full and the
Lenders have no further commitment to lend under the Credit Agreement, the L/C
Exposure has been reduced to zero and the Issuing Bank has no further
obligation to issue Letters of Credit under the Credit Agreement and (b) shall
continue to be effective or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any Obligation is rescinded or must otherwise
be restored by any Secured Party or any Guarantor upon the bankruptcy or
reorganization of the Borrower, any Guarantor or otherwise.

         SECTION 11. BINDING EFFECT; SEVERAL AGREEMENT; ASSIGNMENTS. Whenever
in this Agreement any of the parties hereto is referred to, such reference
shall be deemed to include the successors and assigns of such party; and all
covenants, promises and agreements by or on behalf of the Guarantors that are
contained in this Agreement shall bind and inure to the benefit of each party
hereto and their respective successors and assigns. This Agreement shall become
effective as to any Guarantor when a counterpart hereof executed on behalf of
such Guarantor shall have been delivered to the Collateral Agent, and a
counterpart hereof shall have been executed on behalf of the Collateral Agent,
and thereafter shall be binding upon such Guarantor and the Collateral Agent
and their respective successors and assigns, and shall inure to the benefit of
such Guarantor, the Collateral Agent and the other Secured Parties, and their
respective successors and assigns, except that no Guarantor shall have the
right to assign its rights or obligations hereunder or any interest herein (and
any such attempted assignment shall be void). In the event that a

                                                                              4


Guarantor (a) is designated as an Unrestricted Subsidiary in accordance with
the terms of the Credit Agreement or (b) ceases to be a Subsidiary pursuant to
a transaction permitted under the Loan Documents, such Guarantor shall be
released from its obligations under this Agreement without further action. This
Agreement shall be construed as a separate agreement with respect to each
Guarantor and may be amended, modified, supplemented, waived or released with
respect to any Guarantor without the approval of any other Guarantor and
without affecting the obligations of any other Guarantor hereunder.

         SECTION 12. WAIVERS; AMENDMENT. (a) No failure or delay of the
Collateral Agent in exercising any power or right hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right or
power, or any abandonment or discontinuance of steps to enforce such a right or
power, preclude any other or further exercise thereof or the exercise of any
other right or power. The rights and remedies of the Collateral Agent hereunder
and of the other Secured Parties under the other Loan Documents are cumulative
and are not exclusive of any rights or remedies that they would otherwise have.
No waiver of any provision of this Agreement or consent to any departure by any
Guarantor therefrom shall in any event be effective unless the same shall be
permitted by paragraph (b) below, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. No
notice or demand on any Guarantor in any case shall entitle such Guarantor to
any other or further notice or demand in similar or other circumstances.

         (b) Neither this Agreement nor any provision hereof may be waived,
amended or modified except pursuant to a written agreement entered into between
the Guarantors with respect to which such waiver, amendment or modification
relates and the Collateral Agent, subject to any consent required in accordance
with Section 9.02 of the Credit Agreement.

         SECTION 13. GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

         SECTION 14. NOTICES. All communications and notices hereunder shall be
in writing and given as provided in Section 9.01 of the Credit Agreement. All
communications and notices hereunder to each Guarantor shall be given to it in
care of the Borrower at the address set forth in the Credit Agreement.

         SECTION 15. SURVIVAL OF AGREEMENT; SEVERABILITY. (a) All covenants,
agreements, representations and warranties made by the Guarantors herein and in
the certificates or other instruments prepared or delivered in connection with
or pursuant to this Agreement or any other Loan Document shall be considered to
have been relied upon by the Collateral Agent and the other Secured Parties and
shall survive the making by the Lenders of the Loans and the issuance of the
Letters of Credit by the Issuing Bank regardless of any investigation made by
the Secured Parties or on their behalf, and shall continue in full force and
effect as long as the principal of or any accrued interest on any Loan or any
other fee or amount payable under this Agreement or any other Loan Document is
outstanding and unpaid and as long as the Commitments have not been terminated
or the L/C Exposure does not equal zero.

         (b) In the event any one or more of the provisions contained in this
Agreement or in any other Loan Document should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein and therein shall not in any way be
affected or impaired thereby (it being understood that the invalidity of a
particular provision in a particular jurisdiction shall not in and of itself
affect the validity of such provision in any other jurisdiction). The parties
shall endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

         SECTION 16. COUNTERPARTS. This Agreement may be executed in
counterparts, each of which shall constitute an original, but all of which when
taken together shall constitute a single

                                                                              5


contract, and shall become effective as provided in Section 11. Delivery of an
executed signature page to this Agreement by facsimile transmission shall be as
effective as delivery of a manually executed counterpart of this Agreement.

         SECTION 17. RULES OF INTERPRETATION. The rules of interpretation
specified in Section 1.03 of the Credit Agreement shall be applicable to this
Agreement.

         SECTION 18. JURISDICTION; CONSENT TO SERVICE OF PROCESS. (a) Each
Guarantor hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
Federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement or the other Loan Documents, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably
and unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be conclusive and may
be enforced in other jurisdictions by suit on the judgment or in any other
manner provided by law. Nothing in this Agreement shall affect any right that
the Collateral Agent or any other Secured Party may otherwise have to bring any
action or proceeding relating to this Agreement or the other Loan Documents
against any Guarantor or its properties in the courts of any jurisdiction.

         (b) Each Guarantor hereby irrevocably and unconditionally waives, to
the fullest extent it may legally and effectively do so, any objection that it
may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement or the other Loan
Documents in any New York State or Federal court. Each of the parties hereto
hereby irrevocably waives, to the fullest extent permitted by law, the defense
of an inconvenient forum to the maintenance of such action or proceeding in any
such court.

         (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 14. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

         SECTION 19. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO
THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A
TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT
OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS.
EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF
ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY
WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND
(B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO
ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS APPLICABLE, BY,
AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 19.

         SECTION 20. ADDITIONAL GUARANTORS. Pursuant to Section 5.12 of the
Credit Agreement, each Subsidiary Loan Party of the Borrower that was not in
existence or not a Subsidiary Loan Party on the date of the Credit Agreement
and each Unrestricted Subsidiary that is designated as a Restricted Subsidiary
is required to enter into this Agreement as a Guarantor upon becoming a
Subsidiary Loan Party. Upon execution and delivery after the date hereof by the
Collateral Agent and such a Subsidiary of an instrument in the form of Annex 1,
such Subsidiary shall become a Guarantor hereunder with the same force and
effect as if originally named as a Guarantor herein. The execution and delivery
of any instrument adding an additional Guarantor as a party to this Agreement
shall not require the consent of any other Guarantor hereunder. The rights and
obligations of each Guarantor hereunder shall remain in full force and effect
notwithstanding the addition of any new Guarantor as a party to this Agreement.

         SECTION 21. RIGHT OF SETOFF. If an Event of Default shall have
occurred and be continuing, each Secured Party is hereby authorized at any time
and from time to time, to the fullest extent permitted by law, to set off and
apply any and all deposits (general or special, time or demand, provisional or
final) at any time held and other Indebtedness at any time owing by such
Secured Party to or for the credit or the account of any Guarantor against any
or all the obligations of such Guarantor now or hereafter existing under this
Agreement and the other Loan Documents held by such Secured Party, irrespective
of whether or not such Secured Party shall have made any demand under this
Agreement or any other Loan Document and although such obligations may be
unmatured. The rights of each Secured Party under this Section 21 are in

addition to other rights and remedies (including other rights of setoff) which
such Secured Party may have.

         IN WITNESS WHEREOF, the parties hereto have duly executed this
Agreement as of the day and year first above written.

                           SUPPLEMENT NO. [ ] dated as of      , to the
               Guarantee Agreement dated as of May 7, 1999, among AMERICAN
               MEDIA, INC., a Delaware corporation ("HOLDINGS"), each of the
               subsidiaries listed on Schedule I thereto (each such subsidiary
               individually, a "SUBSIDIARY" and, collectively, the
               "SUBSIDIARIES"; and each such Subsidiary and Holdings,
               individually, a "GUARANTOR" and, collectively, the "GUARANTORS"),
               and THE CHASE MANHATTAN BANK, a New York banking corporation, as
               collateral agent (the "COLLATERAL AGENT") for the Secured Parties
               (as defined in the Security Agreement).

      A. Reference is made to the Credit Agreement dated as of May 7, 1999 (as
amended, supplemented or otherwise modified from time to time, the "CREDIT
AGREEMENT"), among AMERICAN MEDIA OPERATIONS, INC., a Delaware corporation (the
"BORROWER"), Holdings, the lenders from time to time party thereto (the
"LENDERS") and The Chase Manhattan Bank, as administrative agent for the
Lenders (in such capacity, the "ADMINISTRATIVE AGENT").

      B. Capitalized terms used herein and not otherwise defined herein shall
have the meanings assigned to such terms in the Guarantee Agreement and the
Credit Agreement.

      C. The Guarantors have entered into the Guarantee Agreement in order to
induce the Lenders to make Loans and the Issuing Bank to issue Letters of
Credit. Pursuant to Section 5.12 of the Credit Agreement, each Subsidiary Loan
Party of the Borrower that was not in existence or not a Subsidiary Loan Party
on the date of the Credit Agreement and each Unrestricted Subsidiary that is
designated as a Restricted Subsidiary is required to enter into the Guarantee
Agreement as a Guarantor upon becoming a Subsidiary Loan Party. Section 20 of
the Guarantee Agreement provides that additional Subsidiaries of the Borrower
may become Guarantors under the Guarantee Agreement by execution and delivery
of an instrument in the form of this Supplement. The undersigned Subsidiary of
the Borrower (the "NEW GUARANTOR") is executing this Supplement in accordance
with the requirements of the Credit Agreement to become a Guarantor under the
Guarantee Agreement in order to induce the Lenders to make additional Loans and
the Issuing Bank to issue additional Letters of Credit and as consideration for
Loans previously made and Letters of Credit previously issued.

      Accordingly, the Collateral Agent and the New Guarantor agree as follows:

      SECTION 1. In accordance with Section 20 of the Guarantee Agreement, the
New Guarantor by its signature below becomes a Guarantor under the Guarantee
Agreement with the same force and effect as if originally named therein as a
Guarantor and the New Guarantor hereby (a) agrees to all the terms and
provisions of the Guarantee Agreement applicable to it as a Guarantor
thereunder and (b) represents and warrants that the representations and
warranties made by it as a Guarantor thereunder are true and correct on and as
of the date hereof except to the extent a representation and warranty expressly
relates solely to a specific date in which case such representation and
warranty shall be true and correct on such date. Each reference to a
"Guarantor" in the Guarantee Agreement shall be deemed to include the New
Guarantor. The Guarantee Agreement is hereby incorporated herein by reference.

      SECTION 2. The New Guarantor represents and warrants to the Collateral
Agent and the other Secured Parties that this Supplement has been duly
authorized, executed and delivered by it and constitutes its legal, valid and
binding obligation, enforceable against it in accordance with its terms.

      SECTION 3. This Supplement may be executed in counterparts, each of which
shall constitute an original, but all of which when taken together shall
constitute a single contract. This Supplement shall become effective when the
Collateral Agent shall have received counterparts of this Supplement that, when
taken together, bear the signatures of the New Guarantor and the Collateral
Agent. Delivery of an executed signature page to this Supplement by facsimile

transmission shall be as effective as delivery of a manually executed
counterpart of this Supplement.

      SECTION 4. Except as expressly supplemented hereby, the Guarantee
Agreement shall remain in full force and effect.

      SECTION 5. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

      SECTION 6. In case any one or more of the provisions contained in this
Supplement should be held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein and in the Guarantee Agreement shall not in any way be affected or
impaired thereby (it being understood that the invalidity of a particular
provision hereof in a particular jurisdiction shall not in and of itself affect
the validity of such provision in any other jurisdiction). The parties hereto
shall endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

      SECTION 7. All communications and notices hereunder shall be in writing
and given as provided in Section 14 of the Guarantee Agreement. All
communications and notices hereunder to the New Guarantor shall be given to it
at the address set forth under its signature below, with a copy to the
Borrower.

      SECTION 8. The New Guarantor agrees to reimburse the Collateral Agent for
its out-of-pocket expenses in connection with this Supplement, including the
fees, disbursements and other charges of counsel for the Collateral Agent.
