ABBVIE DEFERRED COMPENSATION PLAN

(Effective as of January 1, 2013)

ABBVIE

DEFERRED COMPENSATION PLAN

ARTICLE I

INTRODUCTION

Section 1.1            Purpose.  The AbbVie Deferred Compensation Plan (the “Plan”) is designed to assist the Employers in attracting and retaining key employees by providing Eligible Employees with the opportunity to defer the receipt of a portion of their compensation and to have that deferred compensation treated as if it were invested pending its distribution by the Plan.

Section 1.2            ERISA.  The Plan is intended to be exempt from Parts 2, 3, and 4 of Title I of ERISA and, therefore, participation in the Plan is limited to a select group of management and highly compensated employees, within the meaning of ERISA Sections 201(2), 301(a)(3) and 401(a)(1).

Section 1.3            Employers.

(a)           After the Effective Date, any Subsidiary of the Company that is not then an Employer may adopt the Plan with the Company’s consent as described in Section 13.12.

(b)           Each Employer shall be liable to the Company for an amount equal to the Plan benefits earned by its Eligible Employees.  Where an Eligible Employee has been employed by more than one Employer, the Plan Administrator shall allocate the liability to the Company associated with that Eligible Employee’s Plan benefits among his or her Employers.  The Plan Administrator shall establish procedures for determining the time at which and manner in which the Employers shall pay this liability to the Company.

Section 1.4            Effective Date.  The Plan is adopted and is effective as of January 1, 2013 (the “Effective Date”).

Section 1.5            Transfer of Liabilities from Abbott Laboratories Plan.  As part of the Separation and Distribution Agreement by and between Abbott Laboratories and AbbVie Inc. dated as of November 28, 2012, Abbott and AbbVie entered into the Employee Matters Agreement dated as of December 31, 2012 (the “EMA”).  In accordance with the EMA, all liabilities for AbbVie Employees (as defined in the EMA) under the Abbott Laboratories Deferred Compensation Plan were transferred to the Plan and the Plan became liable to pay all such benefits to such participants.  Supplement A to the Plan sets forth the additional rules applicable to the transferred benefits and transferred participants.

A-5.        Initial Transfer of Liabilities from Abbott DCP.  As soon as practicable after the Separation Date, and subject to such terms and conditions as the Plan Administrator may establish, all liabilities attributable to Transferred Participants shall be transferred from the Abbott DCP to this Plan.  The Plan shall credit each such Transferred Employee’s account with (a) the amount deferred by such individual into the Abbott DCP as of the applicable Transfer Date, plus (b) any employer contributions, whether vested or unvested, deemed to have been made in relation to the amount described in (a), including, in each case, any earnings thereon.

A-6.        Deferral and Distribution Elections.  The Plan shall recognize, implement and honor all deferral and distribution elections made by each Transferred Participant under the Abbott DCP (including, but not limited to, any election to defer any bonus earned during 2012 but paid in 2013).

Re:                             Registration Statement on Form S-8

We have acted as special counsel to AbbVie Inc., a Delaware corporation (the “Company”), in connection with the preparation and filing of the Company’s Registration Statement on Form S-8 (the “Registration Statement”) relating to an aggregate of $60,000,000 of unsecured obligations of the Company to pay deferred compensation in the future (the “Deferred Compensation Obligations”), pursuant to the AbbVie Deferred Compensation Plan (the “Plan”), which Plan will become effective upon the distribution by Abbott Laboratories (“Abbott”) of all of the outstanding shares of the common stock, par value $0.01 per share, of the Company to shareholders of Abbott (the “Distribution”).

In rendering this opinion, we have examined such corporate records and other documents (including the written document constituting the Plan, the Registration Statement and the Company’s certificate of incorporation and by-laws as currently in effect and amendments thereto as contemplated to be in effect at the time of the Distribution), and we have reviewed such matters of law, as we have deemed necessary or appropriate.  In rendering this opinion, we have, with the Company’s consent, relied upon oral and written representations of officers of the Company and certificates of officers of the Company and public officials with respect to the accuracy of the factual matters addressed in such representations and certificates.  In addition, in rendering this opinion we have, with the Company’s consent, assumed the genuineness of all signatures or instruments relied upon by us, and the conformity of certified copies submitted to us with the original documents to which such certified copies relate.  In addition, we have assumed that the Plan will be effective at the time that the Deferred Compensation Obligations will be incurred by the Company.

Our opinion is subject to the effect of (i) bankruptcy, insolvency, fraudulent conveyance, fraudulent transfer, reorganization, moratorium, or other similar laws relating to or affecting the rights or remedies of creditors generally, (ii) the application of general principles of equity (including, without limitation, concepts of materiality, reasonableness, good faith, and fair dealing, regardless of whether enforcement is considered in proceedings at law or in equity), and (iii) applicable law and public policy with respect to rights to indemnity and contribution.  In addition, the manner in which any particular issue relating to the opinions would be treated in any actual court case would depend in part on facts and circumstances particular to the case and would also depend on how the court involved chose to exercise the wide discretionary authority generally available to it.

We are members of the Bar of the State of New York and we express no opinion as to the laws of any jurisdiction other than the federal laws of the United States, the laws of the State of New York and the General Corporation Law of the State of Delaware.

Based on the foregoing and subject to the qualifications and limitations set forth herein, we are of the opinion that the Deferred Compensation Obligations, when incurred pursuant to the terms and conditions set forth in the Registration Statement, the prospectus delivered to participants in the Plan and the Plan, will constitute the valid and legally binding obligations of the Company.

We hereby consent to be named in the Registration Statement and in the related prospectus contained therein as the attorneys who passed upon the validity of the Deferred Compensation Obligations and to the filing of a copy of this opinion as Exhibit 5.1 to the Registration Statement.  In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended.  We assume no obligation to advise you or any other person, or to make any investigations, as to any legal developments or factual matters arising subsequent to the date of effectiveness of the Registration Statement that might affect the opinions expressed herein.

Exhibit 23.1

CONSENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

We consent to the incorporation by reference in this Registration Statement on Form S-8 of our report relating to the combined financial statements of the Research-Based Pharmaceuticals Business of Abbott Laboratories (“AbbVie”) dated June 4, 2012, appearing in AbbVie Inc.’s Registration Statement on Form 10 (Commission File No. 001-35565) for the year ended December 31, 2011.
