      GUARANTY, dated as of April 30, 1999, made by OMNICOM GROUP INC., a
corporation organized and existing under the laws of New York (the "Guarantor").
Except as otherwise defined herein, terms used herein and defined in the Credit

used herein as so defined.

                              W I T N E S S E T H :
                              ---------------------

      WHEREAS, Omnicom Finance Inc. and Omnicom Finance Limited (the
"Borrowers"), various financial institutions (the "Banks"), Citibank, N.A., as
Administrative Agent (the "Administrative Agent") (the Banks and the
Administrative Agent being hereinafter collectively referred to as the
"Guaranteed Parties"), The Bank of Nova Scotia, as Documentation Agent, and
Istituto Bancario San Paolo Di Torino Istituto Mobiliare Italiano S.p.A., as
Syndication Agent, have entered into a 364-Day Credit Agreement, dated as of
April 30, 1999 (as modified, supplemented or amended from time to time, the
"Credit Agreement"), providing for the making of Loans in Dollars as
contemplated therein;

      WHEREAS, it is a condition precedent to the effectiveness of the Credit
Agreement referred to above that the Guaranty be executed and delivered in the
form hereof;

      WHEREAS, it is a condition to the making of Loans under the Credit
Agreement that the Guarantor shall have executed and delivered this Guaranty;
and

      WHEREAS, the Guarantor will obtain benefits as a result of the Loans made
to the Borrowers under the Credit Agreement and, accordingly, desires to execute
and deliver this Guaranty in order to satisfy the conditions described in the
two immediately preceding paragraphs;

      NOW, THEREFORE, in consideration of the foregoing and other benefits
accruing to the Guarantor, the receipt and sufficiency of which are hereby
acknowledged, the Guarantor hereby makes the following representations and
warranties to the Guaranteed Parties and hereby covenants and agrees with the
Guaranteed Parties as follows:

      1. The Guaranty. The Guarantor irrevocably and unconditionally guarantees
the full and prompt payment when due (whether by acceleration or otherwise) of
the principal of and interest on any Note issued under the Credit Agreement and
of all other obligations and liabilities (including, without limitation,
indemnities, fees and interest thereon) of the Borrowers now existing or
hereafter incurred under, arising out of or in connection with the Credit
Agreement and the due performance and compliance with the terms of the Credit
Agreement and the Notes by the Borrowers (all such principal, interest,
obligations and liabilities, collectively, the "Guaranteed Obligations"). All
payments by the Guarantor under this Guaranty, to the extent owing to the Banks
or the Administrative Agent, shall be made on the same basis as payments by the
Borrowers under Sections 5.03 and 5.04 of the Credit Agreement.

      2. Waiver of Notice, Etc. The Guarantor hereby waives notice of acceptance
of this Guaranty and notice of any liability to which it may apply, and waives
presentment, demand of payment, protest, notice of dishonor or nonpayment of any
such liability, suit or taking of other action by any Guaranteed Party against,
and any other notice to, any party liable thereon (including the Guarantor or
any other guarantor).



      3. Waiver of Suretyship Defenses. Any Guaranteed Party may at any time and
from time to time without the consent of, or notice to the Guarantor, without
incurring responsibility to the Guarantor, without impairing or releasing the
obligations of the Guarantor hereunder, upon or without any terms or conditions
and in whole or in part:

        (a) change the manner, place or terms of payment of, and/or change or
     extend the time of payment of, renew or alter, any of the Guaranteed
     Obligations, any security therefor, or any liability incurred directly or
     indirectly in respect thereof, and the guaranty herein made shall apply to
     the Guaranteed Obligations as so changed, extended, renewed or altered;

        (b) sell, exchange, release, surrender, realize upon or otherwise deal
     with in any manner and in any order any property by whomsoever at any time
     pledged or mortgaged to secure, or howsoever securing, the Guaranteed
     Obligations or any liabilities (including any of those hereunder) incurred
     directly or indirectly in respect thereof or hereof, and/or any offset
     thereagainst; 

        (c) exercise or refrain from exercising any rights against the Borrowers
     or others or otherwise act or refrain from acting;

        (d) settle or compromise any of the Guaranteed Obligations, any security
     therefor or any liability (including any of those hereunder) incurred
     directly or indirectly in respect thereof or hereof, and may subordinate
     the payment of all or any part thereof to the payment of any liability
     (whether due or not) of the Borrowers to creditors of the Borrowers other
     than the Guaranteed Parties and the Guarantor;

        (e) apply any sums by whomsoever paid or howsoever realized to any
     liability or liabilities of the Borrowers to the Guaranteed Parties
     regardless of what liability or liabilities of the Borrowers remain unpaid;

        (f) consent to or waive any breach of, or any act, omission or default
     under, any of the Credit Documents, or otherwise amend, modify or
     supplement any of the Credit Documents or any of such other instruments or
     agreements; and/or

        (g) act or fail to act in any manner referred to in this Guaranty which
     may deprive the Guarantor of its right to subrogation against the Borrowers
     to recover full indemnity for any payments made pursuant to this Guaranty.
     
      4. Obligations Unconditional. The obligations of the Guarantor under this
Guaranty are absolute and unconditional and shall remain in full force and
effect without regard to, and shall not be released, suspended, discharged,
terminated or otherwise affected by, any circumstance or occurrence whatsoever,
including, without limitation: (a) any action or inaction by any Guaranteed
Party as contemplated in Section 3 of this Guaranty; (b) any invalidity,
irregularity or unenforceability of all or part of the Guaranteed Obligations or
of any security therefor or (c) to the fullest extent permitted by law, any
other circumstance or occurrence that would or might otherwise release, suspend,
discharge, terminate or otherwise affect the obligations of a surety. This
Guaranty is a primary obligation of the Guarantor, and is a guaranty of payment,
not merely collection.


                                      -2-


        5. Subrogation. (a) The Guarantor hereby waives all rights of
     subrogation which it may at any time otherwise have as a result of this
     Guaranty (whether contractual, under Section 509 of the Bankruptcy Code, or
     otherwise) to the claims of the Guaranteed Parties against the Borrowers or
     any other guarantor of the Guaranteed Obligations (collectively, the "Other
     Parties") and all contractual, statutory or common law rights of
     reimbursement, contribution or indemnity from any Other Party which it may
     at any time otherwise have as a result of this Guaranty. The Guarantor
     hereby further waives any right to enforce any other remedy which the
     Guaranteed Parties now have or may hereafter have against any Other Party,
     any endorser or any other guarantor of all or any part of the indebtedness
     of the Borrowers and any benefit of, and any right to participate in, any
     security or collateral given to or for the benefit of the Guaranteed
     Parties to secure payment of the indebtedness of the Borrowers. The
     Guarantor also waives all claims (as such term is defined in the Bankruptcy
     Code) it may at any time otherwise have against any Other Party arising
     from any transaction whatsoever, including, without limitation, its right
     to assert or enforce any such claims.

        (b) Notwithstanding the provisions of the preceding clause (a), the
     Guarantor shall have and be entitled to (i) all rights of subrogation
     otherwise provided by law in respect of any payment it may make or be
     obligated to make under this Guaranty and (ii) all claims (as defined in
     the Bankruptcy Code) it would have against any Other Party in the absence
     of the preceding clause (a), and to assert and enforce same, provided that
     no Default or Event of Default of the type described in Section 10.05 of
     the Credit Agreement with respect to the respective Other Party exists at
     the time of such assertion and enforcement. 

      6. Representations and Warranties. In order to induce the Banks to make
the Loans, the Guarantor makes the following representations, warranties and
agreements:

        (a) Corporate Existence. Each of the Guarantor and its Subsidiaries (i)
     is a duly organized and validly existing corporation in good standing under
     the laws of the jurisdiction of its incorporation, (ii) has the power and
     authority to own its property and assets and to transact the business in
     which it is engaged and (iii) is duly qualified as a foreign corporation
     and in good standing in each jurisdiction where the ownership, leasing or
     operation of property or the conduct of its business requires such
     qualification, except where the failure to be so qualified could not have a
     material adverse effect on the business, operations, property, assets,
     condition (financial or otherwise) or (to the knowledge of the Guarantor)
     prospects of the Guarantor or of the Guarantor and its Subsidiaries taken
     as a whole.

        (b) Action. The Guarantor has the corporate power to execute, deliver
     and perform the terms and provisions of this Guaranty and has taken all
     necessary corporate action to authorize the execution, delivery and
     performance by it of this Guaranty. The Guarantor has duly executed and
     delivered this Guaranty, and this Guaranty constitutes its legal, valid and
     binding obligation enforceable in accordance with its terms except as the
     enforceability thereof may be limited by applicable bankruptcy, insolvency,
     reorganization or other similar laws affecting creditors' rights generally
     and by general equitable principles (regardless of whether the issue of
     enforceability is considered in a proceeding in equity or at law).


                                      -3-


        (c) No Breach. Neither the execution, delivery or performance by the
     Guarantor of this Guaranty, nor compliance by it with the terms and
     provisions hereof, (i) will contravene any provision of any law, statute,
     rule or regulation or any order, writ, injunction or decree of any court or
     governmental instrumentality, (ii) will conflict or be inconsistent with or
     result in any breach of any of the terms, covenants, conditions or
     provisions of, or constitute a default under, any indenture, mortgage, deed
     of trust, credit agreement, loan agreement or any other agreement, contract
     or instrument to which the Guarantor or any of its Subsidiaries is a party
     or by which it or any of its property or assets is bound or to which it may
     be subject or (iii) will violate any provision of the Certificate of
     Incorporation or By-Laws of the Guarantor or any of its Subsidiaries.

        (d) Approvals. No order, consent, approval, license, authorization or
     validation of, or filing, recording or registration with (except as have
     been obtained or made prior to the date hereof), or exemption by, any
     governmental or public body or authority, or any subdivision thereof, is
     required to authorize, or is required in connection with, (i) the
     execution, delivery and performance of this Guaranty or (ii) the legality,
     validity, binding effect or enforceability of this Guaranty.

        (e) Financial Condition. The consolidated statements of financial
     condition of the Guarantor and its Subsidiaries at December 31, 1998 and
     the related consolidated statements of income and retained earnings and
     cash flow of the Guarantor and its Subsidiaries for the fiscal year ended
     on such date and heretofore furnished to the Banks present fairly, in all
     material respects, the consolidated financial condition of the Guarantor
     and its Subsidiaries at the date of such statements of financial condition
     and the consolidated results of the operations of the Guarantor and its
     Subsidiaries for such fiscal year. All such financial statements have been
     prepared in accordance with generally accepted accounting principles and
     practices consistently applied. From December 31, 1998 through the date
     hereof, there has been no material adverse change in the business,
     operations, property, assets, condition (financial or otherwise) or (to the
     knowledge of the Guarantor) prospects of the Guarantor or of the Guarantor
     and its Subsidiaries taken as a whole.

        (f) Financial Disclosure. Except as fully reflected in the financial
     statements delivered pursuant to the preceding clause (e), there were as of
     the date hereof no liabilities or obligations with respect to the Guarantor
     or any of its Subsidiaries of any nature whatsoever (whether absolute,
     accrued, contingent or otherwise and whether or not due) which, either
     individually or in aggregate, would be materially adverse to the Guarantor
     or to the Guarantor and its Subsidiaries taken as a whole.

        (g) Litigation. There are no actions, suits or proceedings pending or,
     to the best knowledge of the Guarantor, threatened (i) with respect to any
     Credit Document or (ii) that are reasonably likely to materially and
     adversely affect the business, operations, property, assets, condition
     (financial or otherwise) or (to the knowledge of the Guarantor) prospects
     of the Guarantor or of the Guarantor and its Subsidiaries taken as a whole.

        (h) True and Complete Disclosure. All factual information (taken as a
     whole) heretofore or contemporaneously furnished by or on behalf of the
     Guarantor in writing to 


                                      -4-

     for purposes of or in connection with this Guaranty or any transaction
     contemplated herein is, and all other such factual information (taken as a
     whole) hereafter furnished by or on behalf of the Guarantor in writing to
     any Bank will be, true and accurate in all material respects on the date as
     of which such information is dated or certified and does not omit to state
     any fact necessary to make such information (taken as a whole) not
     misleading in any material respect at such time in light of the
     circumstances under which such information was provided.

        (i) Taxes. Each of the Guarantor and its Subsidiaries has filed all tax
     returns required to be filed (taking into account all valid extensions) by
     it and has paid all income taxes payable by it which have become due
     pursuant to such tax returns and all other taxes and assessments payable by
     it which have become due, other than those not yet delinquent and except
     for those contested in good faith and for which adequate reserves have been
     established. Each of the Guarantor and its Subsidiaries has paid, or has
     provided adequate reserves (in the good faith judgment of the management of
     the Guarantor) for the payment of, all federal and state income taxes
     applicable for all prior fiscal years and for the current fiscal year to
     the last day of the fiscal quarter immediately preceding the date hereof.

        (j) Capitalization. As of December 31, 1998, the authorized capital
     stock of the Guarantor consisted of (i) 300,000,000 shares of common stock,
     $.50 par value per share, of which 168,593,398 shares were issued and
     outstanding and (ii) 7,500,000 shares of preferred stock, $1.00 par value
     per share, none of which shares were issued and outstanding. All such
     outstanding shares have been duly and validly issued, are fully paid and
     non-assessable. Other than (x) certain options to purchase 7,190,800 shares
     of common stock of the Guarantor and performance units payable in cash
     and/or common stock in the discretion of the Compensation Committee of the
     Board of Directors of the Guarantor, (y) the Guarantor's 4-1/4% Convertible
     Subordinated Debentures due 2007 and 2-1/4% Convertible Subordinated
     Debentures due 2013, and (z) shares of common stock issuable under certain
     acquisition agreements to which the Guarantor is a party, the Guarantor
     does not have outstanding any securities convertible into or exchangeable
     for its capital stock or outstanding any rights to subscribe for or to
     purchase, or any options for the purchase of, or any agreements providing
     for the issuance (contingent or otherwise) of, or any calls, commitments or
     claims of any character relating to, its capital stock.

        (k) Environmental Matters. Each of the Guarantor and its Subsidiaries is
     in compliance with all applicable statutes, regulations and orders of, and
     all applicable restrictions imposed by, all governmental bodies, domestic
     or foreign, in respect of the conduct of its business and the ownership of
     its property (including applicable statutes, regulations, orders and
     restrictions relating to environmental standards and controls), except such
     noncompliances as would not, in the aggregate, have a material adverse
     effect on the business, operations, property, assets, condition (financial
     or otherwise) or (to the knowledge of the Guarantor) prospects of the
     Guarantor or of the Guarantor and its Subsidiaries taken as a whole.

        (l) Subsidiaries, Etc. Schedule I correctly sets forth the name of each
     Subsidiary of the Guarantor, the percentage ownership (direct and indirect)
     of the Guarantor in the


                                      -5-


     voting securities of each Subsidiary and also identifies the direct owner
     thereof, in each case as of March 29, 1999.

        (m) Investment Company Act. Neither the Guarantor nor any of its
     Subsidiaries is an "investment company" within the meaning of the
     Investment Company Act of 1940, as amended.

        (n) Public Utility Holding Company Act. Neither the Guarantor nor OFI is
     a "holding company," or a "subsidiary company" of a "holding company," or
     an "affiliate" of a "holding company" or a "subsidiary company" of a
     "holding company" within the meaning of the Public Utility Holding Company
     Act of 1935, as amended.

        (o) Ownership of Borrowers. The Guarantor owns all of the capital stock
     of OFI and Diversified Agency Services Limited ("DASL"), and DASL owns all
     of the capital stock of OFL.

        (p) Ownership of Intellectual Property. Each of the Guarantor and its
     Subsidiaries owns all the patents, trademarks, permits, service marks,
     trade names, copyrights, licenses, franchises and formulas, or rights with
     respect to the foregoing, and has obtained assignments of all leases and
     other rights of whatever nature, necessary for the present conduct of its
     business, without any known conflict with the rights of others which, or
     the failure to obtain which, as the case may be, would result in a material
     adverse effect on the business, operations, property, assets, condition
     (financial or otherwise) or (to the knowledge of the Guarantor) prospects
     of the Guarantor or of the Guarantor and its Subsidiaries taken as a whole.

        (q) Margin Stock. All proceeds of each Loan shall be used by each
     Borrower for general corporate purposes, including the repayment of
     maturing Commercial Paper of such Borrower and acquisitions; provided that
     no part of the proceeds of any Loan will be used by the Borrowers to
     purchase or carry any Margin Stock or to extend credit to others for the
     purpose of purchasing or carrying any Margin Stock in violation of
     Regulation T, U or X of the Board of Governors of the Federal Reserve
     Board. Not more than 25% of the value of the assets of the Guarantor or the
     Guarantor and its Subsidiaries subject to the restrictions contained in
     Section 7 of this Guaranty constitute Margin Stock and, at the time of each
     Borrowing, not more than 25% of the value of the assets of the Guarantor or
     the Guarantor and its Subsidiaries subject to the restrictions contained in
     Section 7 of this Guaranty will constitute Margin Stock. Notwithstanding
     the foregoing provisions of this Section 6(q) neither the Guarantor nor any
     of its Subsidiaries (including, without limitation, the Borrowers) will use
     the proceeds of any Loan to purchase the capital stock of any corporation
     in a transaction, or as part of a series of transactions, (i) the purpose
     of which is, at the time of any such purchase, to acquire control of such
     corporation or (ii) the result of which is the ownership by the Guarantor
     and its Subsidiaries (including, without limitation, the Borrowers) of 10%
     or more of the capital stock of such corporation, in either case if the
     Board of Directors of such corporation has publicly announced its
     opposition to such transaction.


                                      -6-


      7. Covenants. The Guarantor hereby covenants and agrees that on and after
the date hereof and until the termination of the Total Commitment and the
repayment in full of the Loans and Notes, together with interest, fees and all
other Obligations incurred under the Credit Agreement:

        (a) Financial Statements, Etc. The Guarantor will furnish to each Bank:

              (i) within 50 days after the close of each quarterly accounting
       period in each fiscal year of the Guarantor (other than the fourth fiscal
       quarterly accounting period), the consolidated statements of financial
       condition of the Guarantor and its Subsidiaries as at the end of such
       quarterly period and the related consolidated statements of income for
       such quarterly period and of cash flow for the elapsed portion of the
       fiscal year ended with the last day of such quarterly period, in each
       case setting forth comparative figures for the related periods in the
       prior fiscal year (or for the last day of the respective fiscal quarter
       in the prior fiscal year in the case of the balance sheet), all of which
       shall be certified by the chief financial officer of the Guarantor,
       subject to normal year-end adjustments;

              (ii) within 105 days after the close of each fiscal year of the
       Guarantor, the consolidated statements of financial condition of the

      9. Continuing Guaranty, Etc. This Guaranty is a continuing one and all
liabilities to which it applies or may apply under the terms hereof shall be
conclusively presumed to have been created in reliance hereon. No failure or
delay on the part of any Guaranteed Party in exercising any right, power or
privilege hereunder and no course of dealing between the Guarantor, any
Guaranteed Party or the holder of any Note shall operate as a waiver thereof;
nor shall any single or partial exercise of any right, power or privilege
hereunder preclude any other or further exercise thereof or the exercise of any
other right, power or privilege. The rights, powers and remedies herein
expressly provided are cumulative and not exclusive of any rights, powers or
remedies which any Guaranteed Party or the holder of any Note would otherwise
have. No notice to or demand on the Guarantor in any case shall entitle the
Guarantor to any other further notice or demand in similar or other
circumstances or constitute a waiver of the rights of any Guaranteed Party or
the holder of any Note to any other or further action in any circumstances
without notice or demand.

      10. Successors and Assigns. This Guaranty shall be binding upon the
Guarantor and its successors and assigns and shall inure to the benefit of the
Guaranteed Parties and their successors and assigns.

      11. Amendments, Etc. Neither this Guaranty nor any provision hereof may be
changed, waived, discharged or terminated except as provided in Section 12.13 of
the Credit Agreement.

      12. Receipt of Credit Agreement. The Guarantor acknowledges that an
executed (or conformed) copy of the Credit Agreement has been made available to
its principal executive officers and such officers are familiar with the
contents thereof.

      13. Setoff. In addition to any rights now or hereafter granted under
applicable law or otherwise, and not by way of limitation of any such rights,
upon the occurrence of an Event of Default each of the Banks is hereby
authorized at any time or from time to time, without presentment, demand,
protest, or other notice of any kind to the Guarantor or to any other Person,
any such notice being hereby expressly waived, to set off and to appropriate and
apply any and all deposits (general or special) and any other Indebtedness at
any time held or owing by such Bank (including, without limitation, by branches
and agencies of such Bank and its affiliates wherever located) to or for the
credit or the account of the Guarantor against and on account of the obligations
of the Guarantor to such Bank under this Guaranty, irrespective of whether or
not such Bank shall have made any demand hereunder and although said
obligations, or any of them, shall be contingent or unmatured.


                                      -17-


      14. Notices. All notices and other communications hereunder shall be made
at the addresses, in the manner and with the effect provided in Section 12.03 of
the Credit Agreement, provided that, for this purpose, the address of the
Guarantor shall be the one specified opposite its signature below.

      15. Reinstatement. If claim is ever made upon any Guaranteed Party or the
holder of any Note for repayment or recovery of any amount or amounts received
in payment or on account of any of the Guaranteed Obligations and any of the
aforesaid payees repays all or part of said amount by reason of (a) any
judgment, decree or order of any court or administrative body having
jurisdiction over such payee or any of its property or (b) any settlement or
compromise of any such claim effected by such payee with any such claimant
(including the Guarantor), the Guarantor shall be and remain liable to the
aforesaid payees hereunder for the amount so repaid or recovered to the same
extent as if such amount had never originally been received by any such payee.

      16. Statute of Limitations. Any acknowledgment or new promise, whether by
payment of principal or interest or otherwise and whether by the Borrower or
others (including the Guarantor), with respect to any of the Guaranteed
Obligations shall, if the statute of limitations in favor of the Guarantor
against any Guaranteed Party or the holder of any Note shall have commenced to
run, toll the running of such statute of limitations, and if the period of such
statute of limitations shall have expired, prevent the operation of such statute
of limitations.

      17. Generally Accepted Accounting Principles. The financial statements to
be furnished to the Banks pursuant hereto shall be made and prepared in
accordance with generally accepted accounting principles in the United States
consistently applied throughout the periods involved (except as set forth in the
notes thereto or as otherwise disclosed in writing by the Guarantor to the
Banks); provided that, except as otherwise specifically provided herein, all
computations determining compliance with Section 7 shall utilize accounting
principles and policies in conformity with those used to prepare the historical
financial statements delivered to the Banks pursuant to Section 6(e).

      18. Governing Law, Submission to Jurisdiction. This Guaranty and the
rights and obligations of the Guaranteed Parties, the holders of the Notes and
the Guarantor hereunder shall be construed in accordance with and governed by
the law of the State of New York. Any legal action or proceeding with respect to
this Guaranty may be brought in the courts of the State of New York, and, by
execution and delivery of this Agreement, the Guarantor hereby irrevocably
accepts for itself and in respect of its property, generally and
unconditionally, the jurisdiction of the aforesaid courts. The Guarantor agrees
that if at any time its principal place of business is not in the City and State
of New York, it will irrevocably designate, appoint and empower an agent for
purposes of this Section, in the City and State of New York, as its designee,
appointee and agent to receive, accept and acknowledge for and on its behalf,
and in respect of its property, service of any and all legal process, summons,
notices and documents which may be served in any such action or proceeding. If
for any reason such designee, appointee and agent shall cease to be available to
act as such, the Guarantor agrees to designate a new designee, appointee and
agent in New York City on the terms and for the purposes of this provision
satisfactory to the Administrative Agent. The Guarantor further irrevocably
consents to the service of process out of any of the aforementioned courts in
any such action or proceeding by the mailing of copies thereof by registered or
certified mail, postage 


                                      -18-


prepaid, to the Guarantor at its address set forth opposite its signature below,
such service to become effective 30 days after such mailing. Nothing herein
shall affect the right of any Guaranteed Party or the holder of any Note to
serve process in any other manner permitted by law or to commence legal
proceedings or otherwise proceed against the Guarantor in any other
jurisdiction. The Guarantor hereby irrevocably waives any objection which it may
now or hereafter have to the laying of venue of any of the aforesaid actions or
proceedings arising out of or in connection with the Guaranty brought in the
courts referred to above and hereby further irrevocably waives and agrees not to
plead or claim in any such court that any such action or proceeding brought in
any such court has been brought in an inconvenient forum.

      19. Judgment Currency. The obligation of the Guarantor to make payment in
Dollars of any Guaranteed Obligations due hereunder shall not be discharged or
satisfied by any tender, or any recovery pursuant to any judgment, which is
expressed in or converted into any currency other than Dollars, except to the
extent such tender or recovery shall result in the actual receipt by the
respective Guaranteed Party in the United States of America of the full amount
of Dollars expressed to be payable in respect of any such Guaranteed
Obligations. The obligation of the Guarantor to make payment in Dollars as
aforesaid shall be enforceable as an alternative or additional cause of action
for the purpose of recovery in Dollars of the amount, if any, by which such
actual receipt shall fall short of the full amount of Dollars expressed to be
payable in respect of any such Guaranteed Obligations, and shall not be affected
by judgment being obtained for any other sums due under this Guaranty.


                                      -19-


      IN WITNESS WHEREOF, the Guarantor has caused this Guaranty to be executed
and delivered as of the date first above written.
