     This registration statement on Form S-8 (this "Registration Statement") is
(i) a new registration statement, (ii) a Post-Effective Amendment No. 1 to VCA
Antech, Inc.'s (the "Registrant") registration statement on Form S-8 (File No.
333-81614), as filed with the Securities and Exchange Commission (the
"Commission") on January 29, 2002 (the "2002 Registration Statement") and (iii)
a Post-Effective Amendment No. 1 to the Registrant's registration statement on
Form S-8 (File No. 333-107557), as filed with the Commission on August 1, 2003
(the "2003 Registration Statement," and together with the 2002 Registration
Statement, the "Prior Registration Statements"). Pursuant to the Prior
Registration Statements, shares of the Registrant's Common Stock were registered
for issuance under the Amended and Restated 1996 Stock Incentive Plan and the
2001 Stock Incentive Plan (collectively, the "Prior Plans").

(1)  This Registration Statement registers 6,000,000 shares of Common Stock
     issuable under the 2006 Equity Incentive Plan (the "2006 Plan"), and not
     previously registered under the Prior Registration Statements. In addition,
     this Registration Statement registers up to 5,791,314 shares of Common
     Stock which were previously registered under the Prior Registration
     Statements for offer or sale under the Prior Plans and which may be offered
     or sold under the 2006 Plan (the "Carried Forward Shares"). The Carried
     Forward Shares consist of (i) 5,408,314 shares of Common Stock allocable to
     outstanding stock options or other awards under the Prior Plans as of
     November 30, 2006, to the extent that on or after November 30, 2006 such
     stock options or other awards expire, are forfeited or otherwise terminate
     without shares of Common Stock being issued, plus (ii) 383,000 shares of
     Common Stock remaining available for issuance under the Prior Plans, but
     not underlying any outstanding stock options or other awards under the
     Prior Plans as of November 30, 2006. Any shares of Common Stock previously
     registered under the Prior Registration Statements and not utilized as
     Carried Forward Shares will remain registered under the Prior Registration
     Statements. In addition, pursuant to Rule 416(a) under the Securities Act
     of 1933, as amended (the "Securities Act"), the number of shares registered
     under this Registration Statement will automatically be increased to cover
     any additional shares of the Registrant's Common Stock that become issuable
     under the 2006 Plan by reason of any stock split, stock dividend,
     recapitalization or other similar transaction.

(2)  Estimated solely for purposes of calculating the registration fee pursuant
     to Rule 457(c) and (h) under the Securities Act, and based upon the average
     of the high and low prices of the Common Stock on the NASDAQ Global Market
     on December 8, 2006.

(3)  Estimated solely for purposes of calculating the registration fee pursuant
     to Rule 457(h) under the Securities Act, and based upon the on the per
     share weighted average exercise price of the options of $30.70.

(4)  The Carried Forward Shares were previously registered under the Prior
     Registration Statements. As a result, no filing fee with respect to those
     shares is required in accordance with Interpretation 89 under Section G of
     the Securities and Exchange Commission Division of Corporate Finance Manual
     of Publicly Available Telephone Interpretations (July 1997) and Instruction
     E to the General Instructions to Form S-8. The Post-Effective Amendments to
     the Prior Registration Statements are filed here to reallocate the Carried
     Forward Shares from the Prior Registration Statements and to carry over the
     registration fees paid for the Carried Forward Shares from the Prior
     Registration Statements.

             STATEMENT PURSUANT TO GENERAL INSTRUCTION E TO FORM S-8

     VCA Antech, Inc. (the "Registrant") has filed this Registration Statement
to register under the Securities Act of 1933, as amended (the "Securities Act")

share, of the Registrant, not previously registered, and up to 5,791,314 shares
of Common Stock, par value $0.001 per share, of the Registrant, which were
previously registered (as further described below), pursuant to the VCA Antech,
Inc. 2006 Equity Incentive Plan (the "2006 Plan"). This Registration Statement
is (i) a new registration statement, (ii) a Post-Effective Amendment No. 1 to
the Registrant' s registration statement on Form S-8 (File No. 333-81614), as
filed with the Securities and Exchange Commission (the "Commission") on January
29, 2002 (the "2002 Registration Statement") and (iii) a Post-Effective
Amendment No. 1 to the Registrant's registration statement on Form S-8 (File No.
333-107557), as filed with the Commission on August 1, 2003 (the "2003
Registration Statement," and together with the 2002 Registration Statement, the
"Prior Registration Statements"). 5,791,314 shares of the Registrant's Common
Stock registered hereby were previously registered for issuance under the Prior
Registration Statements for offer and sale pursuant to the Registrant's Amended
and Restated 1996 Stock Incentive Plan and the 2001 Stock Incentive Plan
(collectively, the "Prior Plans").

     On March 7, 2006, the Board of Directors of the Registrant adopted, subject
to stockholder approval, the 2006 Plan. On June 5, 2006, the 2006 Plan was
approved by the stockholders at the Registrant's annual meeting of stockholders.
The Registrant desires to have the shares of Common Stock registered hereunder
and issuable pursuant to the 2006 Plan to include those shares of Common Stock
described above whose offer and sale were registered under the Prior
Registration Statements. The shares carried over from the Prior Registration
Statements are no longer available for the grant of new awards under the Prior
Plans. This Registration Statement registers 6,000,000 shares of Common Stock
not previously registered under the 2006 Plan. In addition, this Registration
Statement registers up to 5,791,314 shares of Common Stock which were previously
registered under the Prior Registration Statements for offer or sale under the
Prior Plans and which may be offered or sold under the 2006 Plan (the "Carried
Forward Shares"). The Carried Forward Shares consist of (i) 5,408,314 shares of
Common Stock allocable to outstanding stock options or other awards under the
Prior Plans as of November 30, 2006, to the extent that on or after November 30,
2006 such stock options or other awards expire, are forfeited or otherwise
terminate without shares of Common Stock being issued, plus (ii) 383,000 shares
of Common Stock remaining available for issuance under the Prior Plans, but not
underlying any outstanding stock options or other awards under the Prior Plans
as of November 30, 2006. Any shares of Common Stock previously registered under
the Prior Registration Statements and not utilized as Carried Forward Shares
will remain registered under the Prior Registration Statements. Pursuant to Rule
416(a) under the Securities Act, the number of shares registered under this
Registration Statement will automatically be increased to cover any additional
shares of the Registrant's Common Stock that become issuable under the 2006 Plan
by reason of any stock split, stock dividend, recapitalization or other similar
transaction.

     In accordance with the Interpretation 89 under Section G of the Securities
and Exchange Commission Division of Corporate Finance Manual of Publicly
Available Telephone Interpretations (July 1997) and Instruction E to the General
Instructions to Form S-8: (a) the Registrant is (i) carrying over the Carried
Forward Shares from the Prior Registration Statements, and (ii) registering the
offer and sale of 6,000,000 new shares of Common Stock, of which all 11,791,314
shares may be offered and sold under the 2006 Plan pursuant to this Registration
Statement; (b) the registration fee allocable to the Carried Forward Shares paid
in connection with the Prior Registration Statements is carried over in this
Registration Statement; and (c) the Prior Registration Statements are being
amended on a post-effective basis to disclose the number of shares of Common
Stock which may be carried forward from the Prior Registration Statements to
this Registration Statement.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

     The validity of the shares of our Common Stock is being passed upon for us
by Akin Gump Strauss Hauer & Feld LLP, Los Angeles, California. Frank Reddick, a
partner at Akin Gump Strauss Hauer & Feld LLP, is one of our directors and as of
March 31, 2006, beneficially owned approximately 100,000 shares of our Common
Stock, consisting of options to purchase 100,000 shares of our Common Stock.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Subsection (a) of Section 145 of the General Corporation Law of the State
of Delaware ("DGCL") empowers a corporation to indemnify any person who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he or she is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including attorneys'
fees) judgments, fines and amounts paid in settlement actually and reasonably
incurred by him or her in connection with such action, suit or proceeding if he
or she acted in good faith and in a manner he or she reasonably believed to be
in or not opposed to the best interests of the corporation, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful.

     Subsection (b) of Section 145 empowers a corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he or
she acted in any of the capacities set forth in the paragraph above, against
expenses (including attorneys' fees) actually and reasonably incurred by him or
her in connection with the defense or settlement of such action or suit if he or
she acted in good faith and in a manner he or she reasonably believed to be in
or not opposed to the best interests of the corporation, except that no
indemnification may be made in respect of any claim, issue or matter as to which
such person will have been adjudged to be liable to the corporation unless and
only to the extent that the Court of Chancery or the court in which action or
suit was brought will determine upon application that, despite the adjudication
of liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the Court of
Chancery or such other court will deem proper.

     Section 145 further provides that to the extent that a present or former
director or officer of a corporation has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to in
subsections (a) and (b) of Section 145, or in the defense of any claim, issue or
matter therein, he or she will be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by him or her in connection
therewith; that indemnification and advancement of expenses provided by, or
granted pursuant to, Section 145 will not be deemed exclusive of any other
rights to which those seeking indemnification or advancement of expenses may be
entitled, both as to action in his or her official capacity and as to action in
another capacity while holding such office; and empowers the corporation to
purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against any liability asserted against him or her and incurred by him or her in
any such capacity, or arising out of his or her status as such, whether or not
the corporation would have the power to indemnify him or her against such
liabilities under Section 145.

     Section 102(b)(7) of the DGCL provides that a certificate of incorporation
may include a provision which eliminates or limits the personal liability of a
director to the corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the company or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the DGCL, relating to prohibited
dividends or the unlawful purchase or redemption of stock, or (iv) for any
transaction from which the director derives an improper personal benefit.

<PAGE>



     Our certificate of incorporation and bylaws (i) eliminate the personal
liability of our directors and (ii) provide for the indemnification of our
directors and officers to the fullest extent permitted by the DGCL.

     We have entered into indemnification agreements with our directors and
executive officers, in addition to indemnification provided for in our
certificate of incorporation and our bylaws, and intend to enter into
indemnification agreements with any new directors and executive officers in the
future.

     In addition, we have purchased insurance pursuant to which our directors
and officers are insured against liability which they may incur in their
capacity as such.

               (ii) to reflect in the prospectus any facts or events arising

<PAGE>


                    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

                    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 the registration statement;

          PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) 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 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.

          (2)  That, for the purpose of determining any liability under the
               Securities Act, each such post-effective amendment will be deemed
               to be a new registration statement relating to the securities
               offered therein, and the offering of such securities at that time
               will 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 this offering; and

     (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 15(d) of the
          Securities 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 will be deemed to be a new registration statement relating
          to the securities offered therein, and the offering of such securities
          at that time will 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 or 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 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.

This registration statement on Form S-8 (this "Registration Statement") is
(i) a new registration statement, (ii) a Post-Effective Amendment No. 1 to VCA
Antech, Inc.'s (the "Registrant") registration statement on Form S-8 (File No.
333-81614), as filed with the Securities and Exchange Commission (the
"Commission") on January 29, 2002 (the "2002 Registration Statement") and (iii)
a Post-Effective Amendment No. 1 to the Registrant's registration statement on
Form S-8 (File No. 333-107557), as filed with the Commission on August 1, 2003
(the "2003 Registration Statement," and together with the 2002 Registration
Statement, the "Prior Registration Statements"). Pursuant to the Prior
Registration Statements, shares of the Registrant's Common Stock were registered
for issuance under the Amended and Restated 1996 Stock Incentive Plan and the
2001 Stock Incentive Plan (collectively, the "Prior Plans").

(1)  This Registration Statement registers 6,000,000 shares of Common Stock
     issuable under the 2006 Equity Incentive Plan (the "2006 Plan"), and not
     previously registered under the Prior Registration Statements. In addition,
     this Registration Statement registers up to 5,791,314 shares of Common
     Stock which were previously registered under the Prior Registration
     Statements for offer or sale under the Prior Plans and which may be offered
     or sold under the 2006 Plan (the "Carried Forward Shares"). The Carried
     Forward Shares consist of (i) 5,408,314 shares of Common Stock allocable to
     outstanding stock options or other awards under the Prior Plans as of
     November 30, 2006, to the extent that on or after November 30, 2006 such
     stock options or other awards expire, are forfeited or otherwise terminate
     without shares of Common Stock being issued, plus (ii) 383,000 shares of
     Common Stock remaining available for issuance under the Prior Plans, but
     not underlying any outstanding stock options or other awards under the
     Prior Plans as of November 30, 2006. Any shares of Common Stock previously
     registered under the Prior Registration Statements and not utilized as
     Carried Forward Shares will remain registered under the Prior Registration
     Statements. In addition, pursuant to Rule 416(a) under the Securities Act
     of 1933, as amended (the "Securities Act"), the number of shares registered
     under this Registration Statement will automatically be increased to cover
     any additional shares of the Registrant's Common Stock that become issuable
     under the 2006 Plan by reason of any stock split, stock dividend,
     recapitalization or other similar transaction.

(2)  Estimated solely for purposes of calculating the registration fee pursuant
     to Rule 457(c) and (h) under the Securities Act, and based upon the average
     of the high and low prices of the Common Stock on the NASDAQ Global Market
     on December 8, 2006.

(3)  Estimated solely for purposes of calculating the registration fee pursuant
     to Rule 457(h) under the Securities Act, and based upon the on the per
     share weighted average exercise price of the options of $30.70.

(4)  The Carried Forward Shares were previously registered under the Prior
     Registration Statements. As a result, no filing fee with respect to those
     shares is required in accordance with Interpretation 89 under Section G of
     the Securities and Exchange Commission Division of Corporate Finance Manual
     of Publicly Available Telephone Interpretations (July 1997) and Instruction
     E to the General Instructions to Form S-8. The Post-Effective Amendments to
     the Prior Registration Statements are filed here to reallocate the Carried
     Forward Shares from the Prior Registration Statements and to carry over the
     registration fees paid for the Carried Forward Shares from the Prior
     Registration Statements.
STATEMENT PURSUANT TO GENERAL INSTRUCTION E TO FORM S-8

     VCA Antech, Inc. (the "Registrant") has filed this Registration Statement
to register under the Securities Act of 1933, as amended (the "Securities Act")
the offer and sale of 6,000,000 shares of Common Stock, par value $0.001 per
share, of the Registrant, not previously registered, and up to 5,791,314 shares
of Common Stock, par value $0.001 per share, of the Registrant, which were
previously registered (as further described below), pursuant to the VCA Antech,
Inc. 2006 Equity Incentive Plan (the "2006 Plan"). This Registration Statement
is (i) a new registration statement, (ii) a Post-Effective Amendment No. 1 to
the Registrant' s registration statement on Form S-8 (File No. 333-81614), as
filed with the Securities and Exchange Commission (the "Commission") on January
29, 2002 (the "2002 Registration Statement") and (iii) a Post-Effective
Amendment No. 1 to the Registrant's registration statement on Form S-8 (File No.
333-107557), as filed with the Commission on August 1, 2003 (the "2003
Registration Statement," and together with the 2002 Registration Statement, the
"Prior Registration Statements"). 5,791,314 shares of the Registrant's Common
Stock registered hereby were previously registered for issuance under the Prior
Registration Statements for offer and sale pursuant to the Registrant's Amended
and Restated 1996 Stock Incentive Plan and the 2001 Stock Incentive Plan
(collectively, the "Prior Plans").

     On March 7, 2006, the Board of Directors of the Registrant adopted, subject
to stockholder approval, the 2006 Plan. On June 5, 2006, the 2006 Plan was
approved by the stockholders at the Registrant's annual meeting of stockholders.
The Registrant desires to have the shares of Common Stock registered hereunder
and issuable pursuant to the 2006 Plan to include those shares of Common Stock
described above whose offer and sale were registered under the Prior
Registration Statements. The shares carried over from the Prior Registration
Statements are no longer available for the grant of new awards under the Prior
Plans. This Registration Statement registers 6,000,000 shares of Common Stock
not previously registered under the 2006 Plan. In addition, this Registration
Statement registers up to 5,791,314 shares of Common Stock which were previously
registered under the Prior Registration Statements for offer or sale under the
Prior Plans and which may be offered or sold under the 2006 Plan (the "Carried
Forward Shares"). The Carried Forward Shares consist of (i) 5,408,314 shares of
Common Stock allocable to outstanding stock options or other awards under the
Prior Plans as of November 30, 2006, to the extent that on or after November 30,
2006 such stock options or other awards expire, are forfeited or otherwise
terminate without shares of Common Stock being issued, plus (ii) 383,000 shares
of Common Stock remaining available for issuance under the Prior Plans, but not
underlying any outstanding stock options or other awards under the Prior Plans
as of November 30, 2006. Any shares of Common Stock previously registered under
the Prior Registration Statements and not utilized as Carried Forward Shares
will remain registered under the Prior Registration Statements. Pursuant to Rule
416(a) under the Securities Act, the number of shares registered under this
Registration Statement will automatically be increased to cover any additional
shares of the Registrant's Common Stock that become issuable under the 2006 Plan
by reason of any stock split, stock dividend, recapitalization or other similar
transaction.

     In accordance with the Interpretation 89 under Section G of the Securities
and Exchange Commission Division of Corporate Finance Manual of Publicly
Available Telephone Interpretations (July 1997) and Instruction E to the General
Instructions to Form S-8: (a) the Registrant is (i) carrying over the Carried
Forward Shares from the Prior Registration Statements, and (ii) registering the
offer and sale of 6,000,000 new shares of Common Stock, of which all 11,791,314
shares may be offered and sold under the 2006 Plan pursuant to this Registration
Statement; (b) the registration fee allocable to the Carried Forward Shares paid
in connection with the Prior Registration Statements is carried over in this
Registration Statement; and (c) the Prior Registration Statements are being
amended on a post-effective basis to disclose the number of shares of Common
Stock which may be carried forward from the Prior Registration Statements to
this Registration Statement.

Stock, consisting of options to purchase 100,000 shares of our Common Stock.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Subsection (a) of Section 145 of the General Corporation Law of the State
of Delaware ("DGCL") empowers a corporation to indemnify any person who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he or she is or was a director, officer, employee or
agent of the corporation, or is or was serving at the request of the corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust or other enterprise, against expenses (including attorneys'
fees) judgments, fines and amounts paid in settlement actually and reasonably
incurred by him or her in connection with such action, suit or proceeding if he
or she acted in good faith and in a manner he or she reasonably believed to be
in or not opposed to the best interests of the corporation, and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his or her
conduct was unlawful.

     Subsection (b) of Section 145 empowers a corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he or
she acted in any of the capacities set forth in the paragraph above, against
expenses (including attorneys' fees) actually and reasonably incurred by him or
her in connection with the defense or settlement of such action or suit if he or
she acted in good faith and in a manner he or she reasonably believed to be in
or not opposed to the best interests of the corporation, except that no
indemnification may be made in respect of any claim, issue or matter as to which
such person will have been adjudged to be liable to the corporation unless and
only to the extent that the Court of Chancery or the court in which action or
suit was brought will determine upon application that, despite the adjudication
of liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the Court of
Chancery or such other court will deem proper.

     Section 145 further provides that to the extent that a present or former
director or officer of a corporation has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to in
subsections (a) and (b) of Section 145, or in the defense of any claim, issue or
matter therein, he or she will be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by him or her in connection
therewith; that indemnification and advancement of expenses provided by, or
granted pursuant to, Section 145 will not be deemed exclusive of any other
rights to which those seeking indemnification or advancement of expenses may be
entitled, both as to action in his or her official capacity and as to action in
another capacity while holding such office; and empowers the corporation to
purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against any liability asserted against him or her and incurred by him or her in
any such capacity, or arising out of his or her status as such, whether or not
the corporation would have the power to indemnify him or her against such
liabilities under Section 145.

     Section 102(b)(7) of the DGCL provides that a certificate of incorporation
may include a provision which eliminates or limits the personal liability of a
director to the corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the company or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the DGCL, relating to prohibited
dividends or the unlawful purchase or redemption of stock, or (iv) for any
transaction from which the director derives an improper personal benefit.
Our certificate of incorporation and bylaws (i) eliminate the personal
liability of our directors and (ii) provide for the indemnification of our
directors and officers to the fullest extent permitted by the DGCL.

     We have entered into indemnification agreements with our directors and
executive officers, in addition to indemnification provided for in our
certificate of incorporation and our bylaws, and intend to enter into
indemnification agreements with any new directors and executive officers in the
future.

     In addition, we have purchased insurance pursuant to which our directors
and officers are insured against liability which they may incur in their
capacity as such.

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 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 20 percent 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 the registration statement;

          PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) 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 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.

          (2)  That, for the purpose of determining any liability under the
               Securities Act, each such post-effective amendment will be deemed
               to be a new registration statement relating to the securities
               offered therein, and the offering of such securities at that time
               will 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 this offering; and

     (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 15(d) of the
          Securities 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 will be deemed to be a new registration statement relating
          to the securities offered therein, and the offering of such securities
          at that time will 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 or 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 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.
