SCHEDULE 4

RESERVATIONS

The opinions in this Opinion Letter are subject to the following reservations.

1. LIMITATIONS ARISING FROM INSOLVENCY LAW

The enforceability of the Opinion Documents is subject to the provisions of any applicable bankruptcy, insolvency, liquidation or other laws relating to or affecting the enforcement of creditors’ rights generally including statutes of limitation; in particular it is to be noted that:

(a) any provision in the Opinion Documents providing for an event of default, an acceleration or another early termination of the Opinion Documents by reason of a party being subject to proceedings for a judicial reorganisation may not be enforceable;

(b) it is uncertain whether creditors who do not yet hold an enforceable judgment or deed are entitled to share in the proceeds of real estate in the case of a court supervised disposal made in the context of a judicial reorganisation;

(c) if any Belgian Company is declared bankrupt and if the date of its relevant Guarantee is within the pre-bankruptcy suspect period (the so-called “suspect period” may have a duration of up to six months before the declaration of bankruptcy, or more if the bankrupt entity was already in liquidation, whether formally or as a matter of fact, or in judicial reorganisation before its bankruptcy), then there is a risk that its obligations as a Guarantor may be set aside on the grounds that they were assumed without adequate consideration;

(d) restrictions on the enforcement of its rights against other Guarantors and the Issuer imposed that may be imposed on any Belgian Company pursuant to the Guarantees may cease to be effective upon the bankruptcy of such Belgian Company;

(e) any power of attorney or other mandate would lapse on the bankruptcy of the party that granted it, and may lapse on an application for judicial reorganisation;

(f) penalties and liquidated damages may not be enforceable in a judicial reorganisation;

- 11-

CLIFFORD CHANCE LLP            

(g) termination clauses may be subject to a mandatory 15 day grace period in a judicial reorganisation; and

(h) a party subject to judicial reorganisation may in certain circumstances opt not to perform current contracts, without prejudice however to damages resulting from that non performance.

2. ENFORCEABILITY OF CLAIMS

(a) No opinion is given on any issue which may arise out of, or relate to, the giving of financial assistance pursuant to the Belgian Company Code, nor the consequences thereof on the enforceability of any Guarantee.

(b) Periods of grace for the performance of its obligations may be granted by the courts to a debtor who has acted in good faith.

(c) We offer no opinion as to the enforceability of any clause in either Base Indenture, any Guarantee or any Securities that may cause a liability to arise, or a debt becoming due, upon the occurrence of a change of control, to the extent that such provision relates to a change of control over any Belgian Company, until such time as that provision will have been approved by a general meeting (or a unanimous written resolution) of the shareholders of the relevant Belgian Company and a copy of the approval resolutions will have been duly filed with the clerk of the commercial court of Brussels, in respect of Anheuser-Busch InBev SA/NV, or Leuven, in respect of Cobrew NV, in each case in accordance with Article 556 of the Company Code.

3. INDEMNITIES

(a) Provisions for the recovery of legal fees incurred by a party may not be enforceable beyond a maximum amount set by royal decree.

(b) Indemnification provisions in respect of fines or other criminal or administrative penalties may not be enforceable.

4. MISCELLANEOUS MATTERS

(a) The opinions expressed in this Opinion Letter are subject to the effects of any United Nations, European Union or Belgian sanctions or other similar measures implemented or effective in Belgium with respect to any party to the Opinion Documents which is, or is controlled by or otherwise connected with, a person resident in, incorporated in or constituted under the laws of, or

- 12-

CLIFFORD CHANCE LLP            

carrying on business in, a country to which any such sanctions or other similar measures apply, or is otherwise the target of any such sanctions or other similar measures.

(b) The provisions of the Guarantees whereby a Belgian Obligor agrees to subordinate certain intra-group claims, and in certain circumstances to refrain from exercising subrogation rights, taking enforcement steps or demanding payment in respect of these intra-group claims will be recognised as constituting legal, valid and binding obligations as between the parties. There are doubts, however, as to whether these provisions will be effective against a liquidator in the insolvency of such Belgian Obligor or against other third-party creditors of such Belgian Obligor.

(c) Enforcement action by a party established in Belgium may not be admissible before the courts if that party is not properly registered with the trade registry (Banque-Carrefour des entreprises / Kruispuntbank van Ondernemingen).

(d) Article 524 of the Company Code provides that certain transactions entered into by listed companies or subsidiaries of listed companies must be approved by way of a special approval process at the level of the listed company; according to a literal interpretation of said article 524, Anheuser-Busch InBev SA/NV would need to follow this special approval process as a result of the entry to the Opinion Documents by certain of its Subsidiaries; we believe such literal interpretation to be incorrect and consequently that Anheuser-Busch InBev SA/NV has (subject to the assumptions and qualifications set out in this Opinion Letter) duly approved the Opinion Documents to which it is a party.
