(c)            AIC of an indeterminate amount of its (i) senior secured debt securities (“AIC Senior Secured Debt Securities”), (ii) first mortgage bonds (“AIC Bonds”), (iii) senior unsecured debt securities (“AIC Senior Unsecured Debt Securities”), and (iv) preferred stock (“AIC Preferred Stock”, and together with the Ameren Senior Debt Securities, Ameren Subordinated Debt Securities, Common Stock, Ameren Preferred Stock, Stock Purchase Contracts, Stock Purchase Units, UE Senior Secured Debt Securities, UE Bonds, UE Senior Unsecured Debt Securities, UE Preferred Stock, AIC Senior Secured Debt Securities, AIC Bonds, and AIC Senior Unsecured Debt Securities, the “Securities”).

We have reviewed originals (or copies certified or otherwise identified to our satisfaction) of the Registration Statement (including the exhibits thereto), the Restated Articles of Incorporation, as amended (“Ameren Charter”), and By-Laws, as amended, of Ameren, the Restated Articles of Incorporation (“UE Charter”) and Bylaws, as amended, of UE, and the Restated Articles of Incorporation (“AIC Charter”) and Bylaws, as amended, of AIC, each as in effect on the date hereof, corporate and other documents, records and papers and certificates of public officials, and other such documents and materials as we have deemed necessary or appropriate for purposes of this opinion. In connection with such review, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the conformity to the originals of the documents submitted to us as certified or photostatic copies, the authenticity of the originals of such documents and all documents submitted to us as originals and the correctness of all statements of fact contained in such original documents. We have not examined, and are expressing no opinion or belief as to matters relating to, titles to property, franchises or the lien of the UE or AIC mortgage indentures.

On the basis of such review and assuming that (a) the applicable provisions of, and the rules and regulations promulgated under, the Securities Act and the Trust Indenture Act of 1939, as amended, and the securities or “blue sky” laws of applicable states or other jurisdictions shall have been complied with, (b) appropriate resolutions have been adopted by the Board of Directors (or a duly appointed committee thereof) of Ameren, UE, or AIC, as the case may be, and remain effective authorizing the issuance and sale of the applicable Securities, and (c), in the case of Securities issued by UE or AIC, the applicable Securities have been issued and sold upon the terms specified in such resolutions and in any required orders of the Missouri Public Service Commission, the Illinois Commerce Commission, the Federal Energy Regulatory Commission, or other applicable regulatory authorities, we are of the opinion that:

1.             The Ameren Senior Debt Securities and the Ameren Subordinated Debt Securities, as the case may be, will constitute valid and binding obligations of Ameren, except as may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar laws affecting creditors’ rights generally, general equitable principles (whether considered in a proceeding in equity or at law) and concepts of materiality, reasonableness, good faith and fair dealing and the discretion of the court before which any matter is brought (collectively, the “Exceptions”), when:
