<DIV align="left" style="font-size: 10pt; margin-top: 12pt">Item&nbsp;6. <U>Indemnification of Officers and Directors</U>.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;2-405.2 of the Maryland General Corporation Law permits a Maryland corporation to
include in its charter a provision limiting the liability of its directors and officers to the
corporation and its stockholders for money damages except for liability resulting from (a)&nbsp;actual
receipt of an improper benefit or profit in money, property or services for the amount of the
benefit or profit in money, property or services actually received or (b)&nbsp;active and deliberate
dishonesty established by a final judgment which is material to the cause of action. The
Registrant&#146;s charter contains such a provision which eliminates directors&#146; and officers&#146; liability
to the maximum extent permitted by Maryland law.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Section&nbsp;2-418 of Maryland General Corporation Law requires a corporation (unless its charter
provides otherwise, which the Registrant&#146;s charter does not) to indemnify a director or officer who
has been successful, on the merits or otherwise, in the defense of any proceeding to which he is
made a party by reason of his service in that capacity. Maryland law permits a corporation to
indemnify its present and former directors and officers, among others, against judgments,
penalties, fines, settlements and reasonable expenses actually incurred by them in connection with
any proceeding to which they may be made a party by reason of their service in those or other
capacities unless it is established that (a)&nbsp;the act or omission of the director or officer was
material to the matter giving rise to the proceeding and (1)&nbsp;was committed in bad faith or (2)&nbsp;was
the result of active and deliberate dishonesty, (b)&nbsp;the director or officer actually received an
improper personal benefit in money, property or services or (c)&nbsp;in the case of any criminal
proceeding, the director or officer had reasonable cause to believe that the act or omission was
unlawful. However, under Maryland law, a Maryland corporation may not indemnify for an adverse
judgment in a suit by or in the right of the corporation or for a judgment of liability on the
basis that personal benefit was improperly received, unless in either case a court orders
indemnification and then only for expenses. In addition, Maryland law permits a corporation to
advance reasonable expenses to a director or officer upon the corporation&#146;s receipt of (x)&nbsp;a
written affirmation by the director or officer of his good faith belief that he has met the
standard of conduct necessary for indemnification by the corporation and (y)&nbsp;a written undertaking
by him or on his behalf to repay the amount paid or reimbursed by the corporation if it is
ultimately determined that the standard of conduct was not met.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Registrant&#146;s By-Laws require it to indemnify to the fullest extent permitted by Maryland
law in effect from time to time any person who is a present or former director, officer or employee
of the Registrant and who is made a party to any proceeding (including any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or investigative) by
reason of such person&#146;s service in such capacity or as a director, officer, partner, trustee or
employee of any other corporation, partnership, joint venture, trust, employee benefit plan or
other enterprise which he served as such at the request of the Registrant against all judgments,
penalties, fines, settlements and reasonable expenses actually incurred by him in connection with
such proceeding, unless it is established that (a)&nbsp;the act or omission of such person was material
to the matter giving rise to the proceeding and was committed in bad faith or was the result of
active and deliberate dishonesty or (b)&nbsp;such person actually received an improper personal benefit
in money, property or services or (c)&nbsp;in the case of any criminal proceeding, such person had
reasonable cause to believe that the act or omission was unlawful. The Registrant may, with the
approval of its Board of Directors, provide such indemnification to a person who served a
predecessor of the Registrant in any of the capacities described above and to any agent of the
Registrant or a predecessor of the Registrant.</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Registrant maintains a directors&#146; and officers&#146; liability insurance policy. The policy
insures the Registrant&#146;s directors and officers against unindemnified losses ensuing from certain
wrongful acts in their capacities as directors and officers and reimburses the Registrant for those
losses for which it has lawfully indemnified the directors and officers. This policy contains
various exclusions, none of which apply to this offering.

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 the 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 &#147;Calculation of Registration Fee&#148; table in the effective Registration

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of Item&nbsp;9 of this Registration
Statement do not apply if the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed with the Commission by the Registrant
pursuant to Section&nbsp;13 or Section 15(d) of the Exchange Act that are incorporated by reference in
the Registration Statement.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)&nbsp;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.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)&nbsp;To remove from registration by means of a post-effective amendment any of the securities

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;The undersigned Registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Registrant&#146;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&#146;s annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the 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

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;Reference is made to the indemnification provisions described in Item&nbsp;6 of this
Registration Statement. 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
Securities and Exchange Commission such indemnification is against public policy as expressed in
the 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 Act and
will be governed by the final adjudication of such issue.

Item 6.
Indemnification of Officers and Directors
.
Section 2-405.2 of the Maryland General Corporation Law permits a Maryland corporation to
include in its charter a provision limiting the liability of its directors and officers to the
corporation and its stockholders for money damages except for liability resulting from (a) actual
receipt of an improper benefit or profit in money, property or services for the amount of the
benefit or profit in money, property or services actually received or (b) active and deliberate
dishonesty established by a final judgment which is material to the cause of action. The
Registrant's charter contains such a provision which eliminates directors' and officers' liability
to the maximum extent permitted by Maryland law.
Section 2-418 of Maryland General Corporation Law requires a corporation (unless its charter
provides otherwise, which the Registrant's charter does not) to indemnify a director or officer who
has been successful, on the merits or otherwise, in the defense of any proceeding to which he is
made a party by reason of his service in that capacity. Maryland law permits a corporation to
indemnify its present and former directors and officers, among others, against judgments,
penalties, fines, settlements and reasonable expenses actually incurred by them in connection with
any proceeding to which they may be made a party by reason of their service in those or other
capacities unless it is established that (a) the act or omission of the director or officer was
material to the matter giving rise to the proceeding and (1) was committed in bad faith or (2) was
the result of active and deliberate dishonesty, (b) the director or officer actually received an
improper personal benefit in money, property or services or (c) in the case of any criminal
proceeding, the director or officer had reasonable cause to believe that the act or omission was
unlawful. However, under Maryland law, a Maryland corporation may not indemnify for an adverse
judgment in a suit by or in the right of the corporation or for a judgment of liability on the
basis that personal benefit was improperly received, unless in either case a court orders
indemnification and then only for expenses. In addition, Maryland law permits a corporation to
advance reasonable expenses to a director or officer upon the corporation's receipt of (x) a
written affirmation by the director or officer of his good faith belief that he has met the
standard of conduct necessary for indemnification by the corporation and (y) a written undertaking
by him or on his behalf to repay the amount paid or reimbursed by the corporation if it is
ultimately determined that the standard of conduct was not met.
The Registrant's By-Laws require it to indemnify to the fullest extent permitted by Maryland
law in effect from time to time any person who is a present or former director, officer or employee
of the Registrant and who is made a party to any proceeding (including any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or investigative) by
reason of such person's service in such capacity or as a director, officer, partner, trustee or
employee of any other corporation, partnership, joint venture, trust, employee benefit plan or
other enterprise which he served as such at the request of the Registrant against all judgments,
penalties, fines, settlements and reasonable expenses actually incurred by him in connection with
such proceeding, unless it is established that (a) the act or omission of such person was material
to the matter giving rise to the proceeding and was committed in bad faith or was the result of
active and deliberate dishonesty or (b) such person actually received an improper personal benefit
in money, property or services or (c) in the case of any criminal proceeding, such person had
reasonable cause to believe that the act or omission was unlawful. The Registrant may, with the
approval of its Board of Directors, provide such indemnification to a person who served a
predecessor of the Registrant in any of the capacities described above and to any agent of the
Registrant or a predecessor of the Registrant.
The Registrant maintains a directors' and officers' liability insurance policy. The policy
insures the Registrant's directors and officers against unindemnified losses ensuing from certain
wrongful acts in their capacities as directors and officers and reimburses the Registrant for those
losses for which it has lawfully indemnified the directors and officers. This policy contains
various exclusions, none of which apply to this offering.

Item 8.
Exhibits
.
See Exhibit Index following Signatures page in this Registration Statement, which Exhibit
Index is incorporated herein by reference.
The Registrant hereby undertakes that it will submit or has submitted the Plan and any
amendments thereto to the Internal Revenue Service ("IRS") in a timely manner, and has made or will
make all changes required by the IRS in order to qualify the Plan under Section 401 of the Internal
Revenue Code.
Item 9.
Undertakings
.
(a) The undersigned Registrant hereby undertakes:
(1) To file, during any period in which offers or sales are being made, a post-effective
amendment to this Registration Statement:
(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;
(ii) To reflect in the prospectus any facts or events arising after the effective date of the
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 the 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;
(iii) To include any material information with respect to the plan of distribution not
previously disclosed in the Registration Statement or any material change to such information in
the Registration Statement;
provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of Item 9 of this Registration
Statement do not apply if the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed with the Commission by the Registrant
pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in
the Registration Statement.
(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 the 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) Reference is made to the indemnification provisions described in Item 6 of this
Registration Statement. 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
Securities and Exchange Commission such indemnification is against public policy as expressed in
the 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 Act and
will be governed by the final adjudication of such issue.
