  for liabilities and expenses that they may incur in such capacities. In

  criminal action or proceeding, actions that the indemnitee had no reasonable

  respectively.
  
  
  <P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Registrant is party to an underwriting agreement which provides that
  the underwriters are obligated, under certain circumstances, to indemnify the
  Registrant&#146;s directors, officers and controlling persons against certain
  liabilities, including liabilities under the Securities Act. Reference is made
  to the form of Underwriting Agreement filed as Exhibit&nbsp;1.1 to the Registrant&#146;s
  Registration Statement on Form S-1 (File No.&nbsp;333-113594).
  
  
  <P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Registrant has entered into agreements with certain of its officers
  and directors that also provide for such indemnification and expenses and
  liability reimbursement. These agreements require the Registrant to indemnify
  such persons against liabilities that may arise by reason of their status or
  service as officers and directors and to advance their expenses incurred as a
  result of any proceeding against them as to which they could be indemnified.
  
  
  <P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In addition, the Registrant has an existing directors and officers

  Securities Act of 1933 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.

  In addition, pursuant to Rule 416(a), this Registration Statement also
  covers such indeterminate number of additional shares of Common Stock as
  is necessary to eliminate any dilutive effect of any future stock split,
  stock dividend or similar transaction.
  (2)
  Such shares are issuable upon exercise of outstanding options with fixed
  exercise prices. Pursuant to Rule 457(h), the aggregate offering price
  and the fee have been computed upon the basis of the price at which the
  options may be exercised. The offering price per share set forth for such
  shares is the exercise price per share at which such options are
  exercisable.
  (3)
  The price of $9.04 per share, which is the average of the high and low
  prices of common stock as reported on the Nasdaq National Market on
  July 15, 2004, is set forth solely
  for purposes of calculating the filing fee pursuant to
  Rules 457(c) and (h) and has
  been used only for those shares without a fixed exercise price.

  Item 4. Description of Securities.
  Not applicable.
  Item 5. Interests of Named Experts and Counsel.
  Not applicable.
  Item 6. Indemnification of Directors and Officers.
  The Delaware General Corporation Law and the Registrant's charter and
  bylaws provide for indemnification of the Registrant's directors and officers
  for liabilities and expenses that they may incur in such capacities. In
  general, the Registrant will indemnify its directors and officers with respect
  to actions taken by them in good faith in a manner reasonably believed to be
  in, or not opposed to, the Registrant's best interests and, with respect to any
  criminal action or proceeding, actions that the indemnitee had no reasonable
  cause to believe were unlawful. Reference is made to the Registrant's charter
  and bylaws filed as Exhibits 3.1 and 3.2 to this Registration Statement,
  respectively.
  The Registrant is party to an underwriting agreement which provides that
  the underwriters are obligated, under certain circumstances, to indemnify the
  Registrant's directors, officers and controlling persons against certain
  liabilities, including liabilities under the Securities Act. Reference is made
  to the form of Underwriting Agreement filed as Exhibit 1.1 to the Registrant's
  Registration Statement on Form S-1 (File No. 333-113594).
  The Registrant has entered into agreements with certain of its officers
  and directors that also provide for such indemnification and expenses and
  liability reimbursement. These agreements require the Registrant to indemnify
  such persons against liabilities that may arise by reason of their status or
  service as officers and directors and to advance their expenses incurred as a
  result of any proceeding against them as to which they could be indemnified.
  In addition, the Registrant has an existing directors and officers
  liability insurance policy.

  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 of 1933;
  (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
  percent 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) do
  not apply if the Registration Statement is on Form S-3, Form S-8
  or Form F-3, and 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 15(d) of the Securities
  Exchange Act of 1934, as amended, that are incorporated by
  reference in the Registration Statement.
  (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, 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.
  -5-
  Table of Contents
  (b) The undersigned Registrant hereby undertakes, that, for purposes of
  determining any liability under the Securities Act of 1933, each filing
  of the Registrant's annual report pursuant to Section 13(a) or Section
  15(d) of the Securities Exchange Act of 1934 (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) Insofar as indemnification for liabilities arising under the
  Securities Act of 1933 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.
