Item 6.
Indemnification of Directors and Officers.
Section 145 of the General Corporation Law of the State of Delaware (the "DGCL") grants the Registrant the authority to indemnify each of the Registrant's directors and officers
against all expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by a director or officer that is made a party to any threatened, pending or completed action, suit or proceeding
(whether civil, criminal or otherwise), by reason of the fact that such director or officer is or was a director, officer, employee or agent of the Registrant or by reason of the fact that such director or officer, at the Registrant's request,
is or was
II-1
serving as a director, officer, employee or agent of any other corporation or other entity, if such director or officer acted in good faith and in a manner he or she reasonably believed to be in,
or not opposed to, the Registrant's best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful; provided, that in the case of an action, suit or proceeding
against a director or officer that is brought by the Registrant or in the Registrant's right, the Registrant may indemnify such director or officer only in respect of expenses (including attorneys' fees) actually and reasonably incurred by
such director or officer; provided further, that no such indemnity for expenses may be made with respect to any claim, issue or matter as to which such director or officer shall have been adjudged to be liable to the Registrant unless, and only to
the extent that, either the Delaware Court of Chancery or the court in which the action, suit or proceeding against such director or officer was brought shall determine upon application that, despite the adjudication of liability to the Registrant
but in view of all the circumstances of the case, such director or officer is nevertheless fairly and reasonably entitled to indemnity from the Registrant for such expenses in an amount deemed proper by such court.
Unless ordered by a court, the determination of whether a then sitting director or officer has met the applicable standard for indemnity,
i.e., that the director or officer acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the Registrant's best interests, and, with respect to any criminal action or proceeding, had no reasonable cause
to believe that his or her conduct was unlawful, shall be made (i) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, or (ii) by a committee of such directors
designated by majority vote of such directors, even though less than a quorum, or (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (iv) by the Registrant's
stockholders.
Section 145 of the DGCL also authorizes the Registrant to advance expenses (including attorneys'
fees) incurred by a director or officer in defending any action, suit or proceeding against the director or officer prior to a determination of whether the director or officer is actually entitled to indemnity and to purchase insurance for the
benefit of a director or officer against any liability that may be incurred by reason of the fact that the insured was or is a director or officer, regardless of whether the liability insured could have legally been indemnified by the Registrant.
Pursuant to the authority granted the Registrant by Section 145 of the DGCL, the Registrant has provided in the
Registrant's amended and restated certificate of incorporation and bylaws for the indemnification of and advancement of expenses to the Registrant's directors to the fullest extent authorized or permitted by law as from time to time in
effect; provided, however, the Registrant is required to indemnify, or advance expenses to, any such director in connection with an action, suit, claim or proceeding initiated by such director only if the initiation of such action, suit, claim or
proceeding has been authorized or ratified by the Registrant's Board of Directors. The Registrant's bylaws provide that the Registrant may, to the extent authorized by the Registrant's Board of Directors, grant rights of
indemnification and the advancement of expenses (including attorney's fees) to the Registrant's officers. The Registrant's Board of Directors has authorized indemnification of, and advancement of expenses to, the Registrant's
officers serving as such on or after December 1, 2009. The rights authorized by the Registrant's Board of Directors for the indemnification of, and advancement of expenses to, the Registrant's officers serving as such on or after
December 1, 2009 are the same rights that have been afforded the Registrant's directors pursuant to the Registrant's amended and restated certificate of incorporation and bylaws.
The employment agreement between SemManagement, L.L.C., the Registrant's wholly owned subsidiary, and Norman J. Szydlowski, the
Registrant's President and Chief Executive Officer, provides Mr. Szydlowski with indemnification to the maximum extent permitted by the Registrant's amended and restated certificate of incorporation and bylaws, provided such
indemnification shall be on terms no less favorable than provided to any of the Registrant's other executive officers or directors pursuant to a separate written indemnification agreement. Pursuant to the employment agreement, the Registrant
has also agreed to maintain commercially reasonable directors' and officers' insurance covering Mr. Szydlowski in such amount and pursuant to such terms as is typical and customary for companies of similar size and nature as the
Registrant.
The Registrant has also purchased a policy of insurance for the benefit of the Registrant's directors and
officers that provides standard liability coverage.
As permitted by Section 102 of the DGCL, the Registrant's
amended and restated certificate of incorporation provides that each of the Registrant's directors shall not be personally liable to the Registrant or the
II-2
Registrant's stockholders for monetary damages for breach of fiduciary duty as a director; provided, that a director shall be liable for any breach of such director's duty of loyalty to
the Registrant or the Registrant's stockholders, for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, for liability under Section 174 of the DGCL (involving certain unlawful
dividends or stock repurchases), or for any transaction from which such director derived an improper personal benefit.

To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof)
which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value
of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in
the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement; and
(iii)
To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such
information in this Registration Statement;
Provided, however
, that the undertakings set forth in
paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement.
II-3
(2)
That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3)
To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(b)
The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual
report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by
reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(c)
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant
to the foregoing provisions, or otherwise, the Registrant has been advised that, in the opinion of the Commission, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
