         shares of Common Stock issued in connection with earn-out payments,(v)
         shares of Common Stock issued but not freely tradeable prior to the end
         of the 90 day period, and (vi) up to 1,200,000 shares of Common Stock
         to be issued in connection with acquisitions.

                  (g) Not to solicit any offer to buy or offer or sell the
         Debentures by means of any form of general solicitation or general
         advertising (as those terms are used in Regulation D under the
         Securities Act) or in any manner involving a public offering within the
         meaning of Section 4(2) of the Securities Act.

                  (h) Neither the Issuer nor any person acting on behalf of the
         Issuer will engage in any directed selling efforts with respect to the
         Debentures within the meaning of Regulation S, and the Issuer and each
         such person acting on behalf of the Issuer (other than you) has
         complied and will comply with the offering restrictions requirement of
         Regulation S.

                  (i) During the two year period following the Closing Date (or,
         if later, the Option Closing Date) and during the two year period
         following the sale of any Debenture by an affiliate of the Issuer, the
         Issuer shall, if it is not then subject to Section 13 or 15(d) of the
         Exchange Act make available, upon request, to any seller of the
         Debentures or Shares the information concerning the Issuer specified in
         Rule 144A(d)(4) under the Securities Act (so long as such requirement
         is necessary in order to permit holders of the Debentures or Shares to
         effect resales under Rule 144A).

                  (j) The Issuer will not resell any of the Debentures.

                  (k) The Issuer shall use its best efforts to permit the
         Debentures to be designated PORTAL securities in accordance with the
         rules and regulations adopted by the National Association of Securities
         Dealers, Inc. relating to trading in the PORTAL Market.

         5. Offering of Securities; Restrictions on Transfer. (a) You represent
and warrant that you are a qualified institutional buyer within the meaning of
Rule


                                       11


144A under the Securities Act. You agree with the Issuer that (i) you will not
solicit offers for, or offer to sell, the Debentures by any form of general
solicitation or general advertising (as those terms are used in Regulation D
under the Securities Act) or in any manner involving a public offering within
the meaning of Section 4(2) of the Securities Act and (ii) you will solicit
offers for the Debentures only from, and will offer the Debentures only to, (A)
persons you reasonably believe to be qualified institutional buyers or (B)
persons to whom you reasonably believe offers and sales of the Debentures may be
made without registration of the Debentures under the Securities Act in reliance
upon Regulation S thereunder. You also agree that you will offer the Debentures
only to, and will solicit offers for the Debentures only from, persons that in
purchasing such Debentures will be deemed to have represented and agreed as
provided in the Offering Memorandum in the second paragraph under the caption
"Transfer Restrictions" (to the extent such representations are applicable to
the purchaser concerned).

         (b) The Debentures have not been registered under the Securities Act
and may not be offered or sold within the United States or to, or for the
account or benefit of, U.S. persons except in accordance with Regulation S under
the Securities Act or pursuant to another exemption from the registration
requirements of the Securities Act. You represent that you have offered the
Debentures and will offer and sell the Debentures (i) as part of their
distribution at any time and (ii) otherwise until 40 days after the later of the
commencement of the offering and the Closing Date (or Option Closing Date, if
later), only in accordance with Rule 903 of Regulation S or as otherwise
permitted pursuant to paragraph (a) above. Accordingly, neither you, your
affiliates nor any persons acting on your or their behalf have engaged or will
engage in any directed selling efforts with respect to the Debentures, and you
and they have complied and will comply with the offering restrictions
requirement of Regulation S.

         (c) You represent and, during the period of six months from the date of
the Offering Memorandum, agree that (1) you have not offered or sold and will
not offer or sell any Debentures to persons in the United Kingdom except to
persons whose ordinary activities involve them in acquiring, holding, managing
or disposing of investments (as principal or agent) for the purposes of their
businesses or otherwise in circumstances which have not resulted and will not
result in an offer to the public in the United Kingdom within the meaning of the
Public Offers of Securities Regulations 1995


                                       12


("Regulations"); (2) you have complied and will comply with all applicable
provisions of the Financial Services Act 1986 and the Regulations with respect
to anything done by you in relation to the Debentures in, from or otherwise
involving the United Kingdom; and (3) you have only issued or passed on and will
only issue or pass on to any person in the United Kingdom any document received
by you in connection with the issue of the Debentures if that person is of a
kind described in Article 11(3) of the Financial Services Act 1986 (Investment
Advertisements) (Exemptions) Order 1996 or is a person to whom such document may
otherwise lawfully be issued or passed on.

                  (d) You understand that the Debentures have not been and will
not be registered under the Securities and Exchange Law of Japan, and represent
that you have not offered or sold, and agree that you will not offer or sell,
any Debentures, directly or indirectly in Japan or to or from any resident of
Japan except (i) pursuant to an exemption from the registration requirements of
the Securities and Exchange Law of Japan and (ii) in compliance with any other
applicable requirements of Japanese law.

                  (e) You agree that, at or prior to confirmation of sale of
Debentures (other than a sale pursuant to subclauses (A) or (C) of clause "ii"
of paragraph (a) above), you will have sent to each distributor, dealer or
person receiving a selling concession, fee or other remuneration that purchases
Debentures from you during the restricted period a confirmation or notice to
substantially the following effect:

                  "The Securities covered hereby have not been registered under
         the U.S. Securities Act of 1933 (the "Securities Act") and may not be
         offered and sold within the United States or to, or for the account or
         benefit of, U.S. persons (i) as part of their distribution at any time
         or (ii) otherwise until 40 days after the later of the commencement of
         the offering and the final closing date, except in either case in
         accordance with Regulation S (or Rule 144A if available) under the
         Securities Act. Terms used above have the meaning given to them by
         Regulation S."

Terms used in this Section 5 have the meanings given to them by Regulation S.

         6. Indemnification and Contribution. (a) The Issuer agrees to indemnify
and hold harmless you and each


                                       13


person, if any, who controls you within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act from and against any and all
losses, claims, damages or liabilities (including, without limitation, any legal
or other expenses reasonably incurred by you or any such controlling person in
connection with defending or investigating any such action or claim) caused by
any untrue statement or alleged untrue statement of a material fact contained in
either the Offering Memorandum (as amended or supplemented if the Issuer shall
have furnished any amendments or supplements thereto) used during the period set
forth in Section 4(c) above, or caused by any omission or alleged omission to
state therein a material fact necessary to make the statements therein, in light
of the circumstances under which they were made, not misleading, except insofar
as such losses, claims, damages or liabilities are caused by any such untrue
statement or omission or alleged untrue statement or alleged omission based upon
the Furnished Information or information contained in Section 5 hereof.

         (b) You agree to indemnify and hold harmless the Issuer, its directors,
its officers and each person, if any, who controls the Issuer within the meaning
of either Section 15 of the Securities Act or Section 20 of the Exchange Act to
the same extent as the foregoing indemnity from the Issuer to you, but only with
reference to the Furnished Information.

         (c) In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to either paragraph (a) or (b) above, such person (the
"indemnified party") shall promptly notify the person against whom such
indemnity may be sought (the "indemnifying party") in writing and the
indemnifying party, upon request of the indemnified party, shall retain counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party and any others the indemnifying party may designate in such proceeding and
shall pay the fees and disbursements of such counsel related to such proceeding.
In any such proceeding, any indemnified party shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be


                                       14


inappropriate due to actual or potential differing interests between them. It is
understood that the indemnifying party shall not, in connection with any
proceeding or related proceedings in the same jurisdiction, be liable for the
fees and expenses of more than one separate firm (in addition to any local
counsel) for all such indemnified parties and that all such fees and expenses
shall be reimbursed as they are incurred. Such firm shall be designated in
writing by you in the case of parties indemnified pursuant to paragraph (a)
above and by the Issuer in the case of parties indemnified pursuant to paragraph
(b) above. The indemnifying party shall not be liable for any settlement of any
proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party from and against any loss or
liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel as contemplated by the third sentence of this paragraph, the
indemnifying party agrees that it shall be liable for any settlement of any
proceeding effected without its written consent if (i) such settlement is
entered into more than 30 days after receipt by such indemnifying party of the
aforesaid request and (ii) such indemnifying party shall not have reimbursed the
indemnified party in accordance with such request prior to the date of such
settlement; provided nothing herein shall limit the right of a person against
which indemnity is sought to contest in good faith such person's obligation to
so indemnify. No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement of any pending or threatened
proceeding in respect of which any indemnified party is or could have been a
party and indemnity could have been sought hereunder by such indemnified party,
unless such settlement includes an unconditional release of such indemnified
party from all liability on claims that are the subject matter of such
proceeding.

                  (d) If the indemnification provided for in paragraph (a) or
(b) of this Section 6 is unavailable to an indemnified party or insufficient in
respect of any losses, claims, damages or liabilities referred to therein in
connection with the offering of the Debentures, then each indemnifying party
under such paragraph, in lieu of indemnifying such indemnified party thereunder,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (i) in such proportion as
is appropriate to


                                       15


reflect the relative benefits received by the Issuer and you from the offering
of the Debentures or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Issuer on the one hand and you on the other hand in connection with
the matters that resulted in such losses, claims, damages or liabilities, as
well as any other relevant equitable considerations. The relative benefits
received by the Issuer on the one hand and you on the other hand in connection
with the offering of the Debentures shall be deemed to be in the same respective
proportions as the net proceeds from the offering of the Debentures (before
deducting expenses) received by the Issuer and the total discounts and
commissions received by you in respect thereof, in each case as set forth in the
Offering Memorandum, bear to the aggregate offering price of the Debentures. The
relative fault of the Issuer on the one hand and of you on the other hand shall
be determined by reference to, among other things, whether the untrue or alleged
untrue statement or the omission or alleged omission to state a material fact
relates to information supplied by the Issuer or by you, the information
contained in Section 5 hereof and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

         (e) The Issuer and you agree that it would not be just or equitable if
contribution pursuant to this Section 6 were determined by pro rata allocation
or by any other method of allocation that does not take account of the equitable
considerations referred to in paragraph (d) above. The amount paid or payable by
an indemnified party as a result of the losses, claims, damages and liabilities
referred to in paragraph (d) above shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses reasonably incurred by
such indemnified party in connection with investigation or defending any such
action or claim. Notwithstanding the provisions of this Section 6, you shall not
be required to contribute any amount in excess of the amount by which the total
price at which the Debentures resold by you in the initial placement of such
Debentures were offered to investors exceeds the amount of any damages that you
have otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution for Debentures from any person who


                                       16


was not guilty of such fraudulent misrepresentation. The remedies provided for
in this Section 6 are not exclusive and shall not limit any rights or remedies
which may otherwise be available to any indemnified party at law or in equity.

         The indemnity and contribution agreements contained in this Section 6
and the representations and warranties of the Issuer contained in this Agreement
shall remain operative and in full force and effect regardless of (i) any
investigation made by you or on your behalf or any person controlling you or by
or on behalf of the Issuer, its officers or directors or any other person
controlling the Issuer and (ii) acceptance of and payment for any of the
Debentures. The indemnity and contribution agreements contained in this Section
6 shall also remain operative in full force and effect regardless of any
termination of this Agreement.

         7. Termination. This Agreement shall be subject to termination in your
absolute discretion by notice given to the Issuer, if (a) after the execution
and delivery of this Agreement and prior to the Closing Date (i) trading
generally shall have been suspended or materially limited on or by, as the case
may be, any of the New York Stock Exchange, the American Stock Exchange, the
National Association of Securities Dealers, Inc., the Chicago Board of Options
Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii)
trading of any securities of the Issuer shall have been suspended on any
exchange or in any over-the-counter market, (iii) a general moratorium on
commercial banking activities in New York shall have been declared by either
Federal or New York State authorities, or (iv) there shall have occurred any
outbreak or escalation of hostilities or any change in financial markets or any
calamity or crisis that, in your judgment, is material and adverse and (b) in
the case of any of the events specified in clauses (a)(i) through (iv), such
event singly or together with any other such event makes it, in your judgment,
impracticable to market the Debentures on the terms and in the manner
contemplated in the Offering Memorandum.

         If this Agreement shall be terminated by you because of any failure or
refusal on the part of the Issuer to comply with the terms or to fulfill any of
the conditions of this Agreement, or if for any reason (other than owing to a
default by you of your obligations hereunder or to your exercise of your right
to terminate this Agreement pursuant to the preceding paragraph) the Issuer
shall be unable to


                                       17


perform its obligations under this Agreement, the Issuer will reimburse you for
all out-of-pocket expenses (including the fees and disbursements of your
counsel) reasonably incurred by you in connection with the proposed offering of
the Debentures.

         8. Miscellaneous. This Agreement may be signed in any number of
counterparts, each of which shall be an original, with the same effect as if the
signatures thereto and hereto were upon the same instrument.

         This Agreement shall be governed by and construed in accordance with
the internal laws of the State of New York.

         All notices and other communications hereunder shall be in writing and
shall be deemed to have been duly given if mailed or transmitted by any standard
form of telecommunication. Notices to you shall be directed to you at the
address shown above; notices to the Issuer shall be directed to it at 437
Madison Avenue, New York, New York 10022; Attention: Chief Financial Officer,
telephone no. (212) 415-3631, telecopy no. (212) 415-3536.

         This Agreement shall inure to the benefit of and be binding upon you
and the Issuer and your and its respective successors. Nothing expressed or
mentioned in this Agreement is intended or shall be construed to give any
person, firm or corporation, other than the parties hereto and their respective
successors and the controlling persons and officers and directors referred to in
Section 6 and their heirs and legal representatives, any legal or equitable
right, remedy or claim under or in respect of this Agreement.

         The headings of the sections of this Agreement have been inserted for
convenience of reference only and shall not be deemed a part this Agreement.

                   Re: Omnicom Group Inc.

Ladies and Gentlemen:

         We have acted as counsel for Omnicom Group Inc. (the "Company") in
connection with your purchase of $200,000,000 aggregate principal amount of 2
1/4% Convertible Subordinated Debentures Due 2013 (the "Debentures") pursuant to
the Placement Agreement dated December 4, 1997 (the "Agreement") between the
Company and you. Except as otherwise indicated, the terms used in this letter
have the meanings ascribed to them in the Agreement.

         In rendering the opinions expressed below, we have examined originals

the Company's Restated Certificate of Incorporation and Bylaws, each as amended,
and minutes of the corporate proceedings of the Company relating thereto, (ii)

between the Company and The Chase Manhattan Bank, as Trustee, pursuant to which
the Debentures are being issued, (iv) the Registration Rights Agreement dated

Memorandum and (vi) the forms of the Debentures and Shares.

         For the purposes hereof, we have assumed, with your permission and
without independent verification of any kind; (a) that the signatures of persons
(other than the Company) signing all documents in connection with which this
opinion is rendered are genuine and authorized; (b) the legal capacity of all
natural persons; (c) that all documents submitted to us as originals or
duplicate originals are authentic; and (d) that all documents submitted to us as

questions of fact relevant to this opinion, we have assumed the accuracy of the
representations and warranties of the Company in the applicable Agreements and
have relied upon certificates and oral or written statements and other
information of public officials, officers and representatives of the Company.

         In rendering the opinions expressed below, we have assumed, with your
permission and without any independent investigation or verification of any
kind, that: (i) each party to the Agreements other than the Company
(individually, the "Other Party" and collectively, the "Other Parties") has been
duly incorporated and is validly existing and in good standing under the laws of
its jurisdiction of incorporation and of each other jurisdiction in which the
conduct of its business or the ownership of its property makes such
qualification necessary; (ii) each of the Other Parties has full power and
authority to execute, deliver and perform the Agreements to which it is a party;
(iii) the execution, delivery and performance of the Agreements by each of the
Other Parties has been duly authorized by all requisite corporate action on the
part of each Other Party; (iv) the Agreements have been duly executed and
delivered by each of the Other Parties; and (v) the execution, delivery and
performance of the Agreements by each of the Other Parties does not and will not
violate the charter, by-laws or other organizational documents of any of the
Other Parties. We have further assumed, with your permission and without any
independent investigation or verification of any kind, that the Agreements
constitute the valid and binding obligations of each party thereto other than
the Company.



Morgan Stanley & Co.                    3                        January 6, 1998

         The opinion expressed in paragraph numbered 7 below, is limited solely
to those facts and laws in existence on the date hereof, and in giving such
opinion, we have relied upon a certificate of an officer of the Company which
specifically identifies, and states that we have received copies of, each
indenture, mortgage, deed of trust, credit agreement, loan agreement and any
other similar material agreement, contract or instrument to which the Company,
or any of the companies set forth in paragraph 2 below, as the case may be, is a
party or by which it or any of its property or assets is bound or to which it
may be subject. In giving the opinion set forth in paragraph numbered 8 below,
we have relied upon a certificate of an officer of the Company describing
actions, suits and proceedings currently pending or threatened against the
Company, that if adversely determined, are reasonably likely to materially and
adversely affect the operations, business, property, assets, condition
(financial or otherwise) or (to the best knowledge of the Company) prospects of
the Company. Copies of the certificates referred to in this paragraph are
attached at the end of this opinion. Furthermore, in giving the opinions
expressed in paragraph numbered 7 below, we express no opinion as to state
securities or blue sky laws.

         Based on the foregoing, and such examination of law as we have deemed
necessary, we are of the opinion that:

                  1. The Company has been duly incorporated, is validly existing
         as a corporation in good standing under the laws of the State of New
         York and is duly qualified to transact business as a foreign
         corporation and is in good standing in each jurisdiction in which the
         conduct of its business or its ownership or leasing of property
         requires such qualification, except to the extent that the failure to
         be so qualified or be in good standing would not have a material
         adverse effect on the Company and its subsidiaries taken as a whole.

                  2. Each of BBDO Worldwide Inc., The DDB Needham Worldwide
         Communications Group Inc., TBWA Chiat/Day Inc., Omnicom Finance Inc.,
         BBDO Detroit Inc., DDB Needham Worldwide Partners Inc., and DDB Needham
         Chicago Inc. has been duly incorporated, is validly existing as a
         corporation in good standing under the laws of the jurisdiction of its
         incorporation and is duly qualified to transact business and is in good



Morgan Stanley & Co.                    4                        January 6, 1998
  Incorporated


         standing in each jurisdiction in which the conduct of its business or
         its ownership or leasing of property requires such qualification,
         except to the extent that failure to be so qualified or be in good
         standing would not have a material adverse effect on the Company and
         its subsidiaries taken as a whole.

                  3. Each of the Indenture and the Registration Rights Agreement
         has been duly authorized, executed and delivered by the Company and is
         a valid and binding agreement of the Company.

                  4. The Debentures have been duly authorized and, when executed
         and authenticated in accordance with the provisions of the Indenture
         and delivered to and paid for by you in accordance with the terms of
         the Agreement, will be valid and binding obligations of the Company and
         will be entitled to the benefits of the Indenture.

                  5. The shares of Common Stock initially issuable on conversion
         of the Debentures have been duly authorized and reserved for issuance
         upon such conversion and, when issued upon conversion in accordance
         with the terms of the Indenture, will have been validly issued, fully
         paid and non-assessable, and the issuance of such shares is not subject
         to any preemptive or similar rights.

                  6. The Agreement has been duly authorized, executed and
         delivered by the Company and is a valid and binding agreement of the
         Company, except as rights to indemnity and contribution thereunder may
         be limited under applicable law.

                  7. The execution and delivery by the Company of, and the
         performance by the Company of its obligations under, the Agreement, the
         Debentures, the Indenture and the Registration Rights Agreement, will
         not contravene any provisions of applicable law or the certificate of
         incorporation or the bylaws of the Company or to our knowledge after
         inquiry, any material agreement or other instrument binding upon the
         Company, and no consent, approval or authorization of any governmental
         body or agency is required for the performance by the Company of its
         obligations under the Agreement, the



Morgan Stanley & Co.                    5                        January 6, 1998
  Incorporated


         Debentures, the Indenture and the Registration Rights Agreement.

                  8. After due inquiry of responsible officers of the Company,
         we do not know of any legal or governmental proceeding pending or
         threatened to which the Company or any of its subsidiaries is a party
         that, if determined adversely to the Company or its subsidiaries, would
         have a material adverse effect on the Company and its subsidiaries
         taken as a whole, or in any manner questions the validity of the
         Agreement, the Indenture, the Debentures or the Registration Rights
         Agreement.

                  9. Based upon the representations, warranties and agreements
         of the Company in Sections 1(p) and (q) of the Agreement and of the
         Initial Purchaser (as defined in the Offering Memorandum) in Section 5
         of the Agreement and on the representations, warranties and agreements
         contained in the Section "Transfer Restrictions" of the Offering
         Memorandum, it is not necessary in connection with the offer, sale and
         delivery of the Debentures to the Initial Purchaser under the Agreement
         or in connection with the initial resale of such Debentures by the
         Initial Purchaser in accordance with Section 5 of the Agreement to
         register the Debentures or the Shares (other than as required by the
         Registration Rights Agreement) under the Securities Act of 1933, as
         amended, or to qualify the Indenture under the Trust Indenture Act of
         1939, as amended, it being understood that no opinion is expressed as
         to any subsequent resale of any Debenture or Share.

                  10. The Company is not an "investment company" as such term is
         defined in the Investment Company Act of 1940, as amended.

                  11. The statements in the Offering Memorandum under the
         captions "Description of Debentures," "Description of Capital Stock,"
         "Plan of Distribution" and "Transfer Restrictions," insofar as such
         statements constitute a summary of the legal matters, documents or
         proceedings referred to therein, fairly present the information called
         for with respect to such legal matters, documents and proceedings and
         fairly summarize the matters referred to therein.



Morgan Stanley & Co.                    6                        January 6, 1998

                  12. Each document incorporated by reference in the Offering
         Memorandum (except for financial statements and schedules and other
         statistical and financial data included therein as to which we express
         no opinion), complied as to form when filed with the Commission in all
         material respects with the Securities Exchange Act of 1934, as amended,
         and the rules and regulations of the Commission thereunder.

         Our opinions are subject to the qualifications that:

         A. The enforceability of the Agreements is subject to the effect of any
applicable bankruptcy, insolvency, moratorium, reorganization, marshaling or
other similar law or rule of law affecting creditor's rights generally
(including such as may deny giving effect to waivers of debtors' or guarantors'
rights), and to the discretionary nature of equitable remedies.

         B. The enforcement of any rights under any of the Agreements are in all
cases subject to each party's implied duty of good faith and to general
principles of equity (regardless of whether enforcement is considered in a
proceeding at law or in equity). Consequently, no opinion is given herein as to
(i) the availability of the right to accelerate any obligation and certain
remedies provided for in the Agreements in the event of a nonmaterial default or
(ii) the enforceability of any provision of the Agreements relating to
cumulation of remedies or waiving the remedy of specific performance.

         C. We express no opinion as to the enforceability of any contractual
provision in the Agreements relating to indemnification, or waiver of jury
trial, process or other procedural right, to the extent enforcement thereof is
contrary to federal or state securities laws and the public policy underlying
such laws.

         D. We express no opinion as to the enforceability of any right or
obligation to the extent that the same has been varied by course of dealing or
performance.

         We have represented the Company in the preparation of the Offering
Memorandum (but not the documents included



Morgan Stanley & Co.                    7                        January 6, 1998

therein by reference) and in connection therewith participated in conferences
with your representatives, your counsel, and representatives of the Company, at
which the contents of the Offering Memorandum (including documents included
therein by reference) were reviewed and discussed. We have not independently
verified the accuracy, completeness or fairness of the statements made or
included in the Offering Memorandum (or the documents incorporated therein by
reference) except with respect to matters referred to in paragraph 11 above.

         On the basis of the information which was developed in the course of
our participation referred to above, considered in the light of our
understanding of the applicable United States law and the experience we have
gained through our practice thereunder, we have no reason to believe that the
Offering Memorandum (except for financial statements, and other financial and
statistical information included or incorporated by reference therein, as to
which we do not express any opinion), as of its date contained or on the date
hereof contains any untrue statement of a material fact or omitted or omits to
state a material fact necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading.

         The opinions set forth in this letter relate only to the federal laws
of the United States of America, the laws of the State of New York and the
General Corporation Law of the State of Delaware.

         This letter is furnished by us as counsel to the Company to you under
the Agreement and is solely for your benefit and, other than the Trustee under
the Indenture who may rely upon this opinion as if it were addressed to it, may
not be relied upon by any other person, firm or entity whatsoever for any
purpose.

                                            Very truly yours,



                                                                       EXHIBIT B

                       [OPINION OF DAVIS POLK & WARDWELL]

                                                     January 6, 1998

Ladies and Gentlemen:

         We have acted as counsel for you in connection with your purchase
pursuant to the Placement Agreement dated December 4, 1997 (the "Agreement"),
with Omnicom Group Inc. (the "Company") of $200,000,000 aggregate principal
amount of 2 1/4% Convertible Subordinated Debentures Due 2013 (the "Debentures")
issued pursuant to the Indenture dated as of January 6, 1998 (the "Indenture")
between the Company and The Chase Manhattan Bank, as Trustee. Except as
otherwise indicated, the terms used in this letter have the meanings ascribed to
them in the Agreement.

         We have examined originals or copies, certified or otherwise identified
to our satisfaction, of such documents, corporate records, certificates of
public officials and other instruments as we have deemed necessary for the
purposes of rendering this opinion.

         We have participated in the preparation of the Company's Offering
Memorandum dated December 4, 1997 (other than the documents incorporated therein
by reference (the "Incorporated Documents")) relating to the Debentures.
Although we did not participate in the preparation of the Incorporated
Documents, we have reviewed such documents. The Offering Memorandum dated
December 4, 1997 (including the Incorporated Documents) is hereinafter called
the "Offering Memorandum."

         On the basis of the foregoing, we are of the opinion that:



Morgan Stanley & Co.                    2                        January 6, 1998

                  1. Each of the Indenture and the Registration Rights Agreement
         has been duly authorized, executed and &delivered by the Company and is
         a valid and binding agreement of the Company.

                  2. The Debentures have been duly authorized, and, when
         executed and authenticated in accordance with the provisions of the
         Indenture and delivered to and paid for by you in accordance with the
         terms of the Agreement, will be valid and binding obligations of the
         Company and will be entitled to the benefits of the Indenture.

                  3. The shares of Common Stock initially issuable upon
         conversion of the Debentures have been duly authorized and reserved for
         issuance upon such conversion and, when issued upon conversion and
         delivered in accordance with the terms of the Indenture, will be
         validly issued, fully paid and non-assessable, and the issuance of the
         Shares is not subject to any preemptive or similar rights.

                  4. The Agreement has been duly authorized, executed and
         delivered by the Company and is a valid and binding agreement of the
         Company, except as rights to indemnity and contribution thereunder may
         be limited under applicable law.

                  5. Based upon the representations, warranties and agreements
         of the Company in Sections 1(p) and (q) of the Agreement and of the
         Initial Purchaser (as defined in the Offering Memorandum) in Section 5
         of the Agreement and on the representations and agreements contained in
         the section "Transfer Restrictions" of the Offering Memorandum, it is
         not necessary in connection with the offer, sale and delivery of the
         Debentures to the Initial Purchaser under the Agreement or in
         connection with the initial resale of such Debentures by the Initial
         Purchaser in accordance with Section 5 of the Agreement to register the
         Debentures or the Shares under the Securities Act of 1933, as amended,
         or to qualify the Indenture under the Trust Indenture Act of 1939, as
         amended, it being understood that no opinion is expressed as to any
         subsequent resale of any Debenture or Share.

         We have considered the matters required to be included in the Offering
Memorandum and the information contained therein. We are of the opinion that the



Morgan Stanley & Co.                    3                        January 6, 1998
  Incorporated


statements in the Offering Memorandum under "Description of Debentures",
"Description of Capital Stock", "Plan of Distribution" and "Transfer
Restrictions", insofar as such statements constitute a summary of the legal
matters and documents referred to therein, fairly present the information called
for with respect to such legal matters and documents.

         We have not ourselves checked the accuracy or completeness of, or
otherwise verified, the information furnished with respect to other matters in
the Offering Memorandum. We have generally reviewed and discussed with certain
officers and employees of the Company, counsel for the Company, independent
public accountants for the Company and your representatives the information
furnished, whether or not subject to our check and verification. On the basis of
such consideration, review and discussions, but without independent check or
verification, except as stated, we believe that (except for financial statements
and other financial and statistical information, as to which we are not called
upon to express a belief) the Offering Memorandum as of its date did not and on
the date hereof does not contain any untrue statement of a material fact or omit
to state a material fact necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading.

         We have examined the opinion dated today of Davis & Gilbert, counsel
for the Company, delivered to you pursuant to Section 3(d) of the Agreement and
it is substantially responsive to the requirements of the Agreement and
satisfactory as to scope. We have examined a letter from Davis & Gilbert, tax
counsel to the Company, delivered to you pursuant to Section 3(f) of the
Agreement and it is substantially responsive to the requirements therefor. We
have also examined the letters dated December 4, 1997 and today, addressed to
you of Arthur Andersen LLP, independent public accountants, and delivered to you
pursuant to Section 3(g) of the Agreement relating to the financial statements
and certain financial information contained in the Offering Memorandum. We
participated in discussions with representatives of Arthur Andersen LLP and your
representatives relating to the forms of such letters and we believe that they
are substantially in the respective forms agreed to.

         We are members of the Bar of the State of New York and the foregoing
opinion is limited to the laws of the



Morgan Stanley & Co.                    4                        January 6, 1998

State of New York and the federal laws of the United States of America.

         This opinion is rendered solely to you pursuant to the Agreement. This
opinion may not be relied upon by or furnished to any other person without our
prior written consent.

                                            Very truly yours,
