This consolidated charter sets forth the purpose, authority and responsibilities of the Audit Committees of the Boards of Directors of Excelsior Private
Equity Fund II, Inc., (Fund II) and the Boards of Managers of Excelsior Venture Partners III, LLC (Partners III) and Excelsior Venture Investors III, LLC (Investors III) (the Board in this Charter
shall be understood to refer to each Board acting separately and references to the Company shall be understood to refer to each of Fund II, Partners III and Investors III, each of which is adopting this consolidated charter).

Purposes

The Audit Committee of each Board (the
Committee, which term refers to each Committee separately) has, as its primary purpose, oversight responsibility with respect to: (a) the adequacy of the Companys accounting and financial reporting processes, policies and
practices; (b) the integrity of the Companys financial statements and the independent audit thereof; (c) the adequacy of the Companys overall system of internal controls and, as appropriate, the internal controls of certain
service providers; (d) the Companys compliance with certain legal and regulatory requirements; (e) determining the qualification and independence of the Companys independent auditors; and (f) the Companys internal
audit function.

Authority

The
Committee has been duly established by the Board and shall have the resources and authority appropriate to discharge its responsibilities, including the authority to retain counsel and other experts or consultants at the expense of the Company. The
Committee has the authority and responsibility to retain and terminate the Companys independent auditors. In connection therewith, the Committee must evaluate the independence of the Companys independent auditors and receive the
auditors specific representations as to their independence.

Composition and Term of Committee Members

The Committee shall be comprised of the Directors or Managers who are Independent Directors or Managers, which term shall mean each Director
or Manager (i) who is not an interested person, as defined in the Investment Company Act of 1940, as amended, of the Company; and (ii) who has not accepted directly or indirectly any consulting, advisory, or other compensatory
fee from the Company (other than fees for serving as a Director or Manager or member of such Companys Audit Committee). The members of the Committee shall designate one member to serve as Chairman of the Committee, with Mr. Gene M.
Bernstein serving as the initial Chairman of the Committee.

Each member of the Committee shall serve until a successor is appointed.

The Board shall determine whether: (i) the Committee has at least one member who is an audit committee financial expert,
(ACFE) as such term is defined in the rules adopted under Section 407 of the Sarbanes-Oxley Act of 2002. The designation of a person as an ACFE is not intended to impose any greater responsibility or liability on that person than
the responsibility and liability imposed on such person as a member of the Committee, nor does it decrease the duties and obligations of other Committee members or the Board.
