Re:500,000 Shares of Common Stock, No Par Value
Ladies and Gentlemen:
We refer to the Registration Statement on Form S-8 (the “Registration Statement”) being filed by Wintrust Financial Corporation, an Illinois corporation (the “Company”), with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), in connection with the registration of 500,000 shares of common stock, no par value, of the Company (the “Plan Shares”), that may be issued under the Wintrust Financial Corporation 2007 Stock Incentive Plan (the “Plan”).
In rendering this opinion letter, we have examined and relied upon a copy of the Registration Statement and Exhibits thereto (including the Plan). We have also examined and relied upon originals, or copies of originals certified to our satisfaction, of such agreements, documents, certificates and statements of governmental officials and other instruments, and have examined such questions of law and have satisfied ourselves as to such matters of fact, as we have considered relevant and necessary as a basis for this opinion letter. We have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the legal capacity of all natural persons and the conformity with the original documents of any copies thereof submitted to us for our examination.
Based on the forgoing, and subject to the qualifications and limitations hereinafter set forth, we are of the opinion that:
| 1. | | The Company is duly incorporated and validly existing under the laws of the State of Illinois. |
| |
| 2. | | Each Plan Share will be legally issued, fully paid and nonassessable when: (i) the Registration Statement shall have become effective under the Securities Act; (ii) such Plan Share shall have been validly issued and delivered in accordance with the Plan; and (iii) a certificate representing such Plan Share shall have been duly executed, countersigned and registered and duly delivered to the person entitled thereto against receipt of the agreed consideration therefor to the extent required by, and in accordance with the terms of, the Plan. |
This opinion letter is limited to the Illinois Business Corporation Act and the Securities Act.
We do not find it necessary for the purposes of this opinion letter to cover, and accordingly we express no opinion as to, the application of the securities or “blue sky” laws of the various states or the District of Columbia to the issuance or sale of the Plan Shares.
