(1)  Estimated pursuant to Rule 457 of Regulation C solely for the purpose of
     calculating the registration fee. The proposed maximum offering price per
     share with respect to the additional 200,000 shares recently authorized and
     reserved for issuance under the 1993 Employee Stock Purchase Plan has been
     estimated to be 85% of the average of the high and low prices reported in
     the Nasdaq National Market on June 22, 1998.

(2)  Estimated pursuant to Rule 457 of Regulation C solely for the purpose of
     calculating the registration fee. The proposed maximum offering price per
     share with respect to the 500,000 shares authorized and reserved for
     issuance under the 1995 Long-Term Incentive Plan has been estimated to be
     the average of the high and low prices reported in the Nasdaq National
     Market on June 22, 1998.

(3)  Amount of Registration Fee was calculated pursuant to Section 6(b) of the
     Securities Act of 1933, which states that the fee shall be "$295 per $1
     million " of the maximum aggregate price at which such securities are
     proposed to be offered. The Registration Fees are therefore calculated by
     multiplying the aggregate offering or sales amount by 0.000295.

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


ITEM 3. INFORMATION INCORPORATED BY REFERENCE.

        There are hereby incorporated by reference in this Registration
Statement the following documents and information heretofore filed with the
Securities and Exchange Commission (the "SEC"):

        (a)    The Company's Annual Report on Form 10-K filed with the SEC for
               the year ended December 31, 1997.

        (c)    The description of the Registrant's Common Stock to be offered
               hereby is contained in the Registrant's Registration Statement on
               Form 8-A filed with the Securities and Exchange Commission on
               October 21, 1993 pursuant to Section 12(g) of the Securities
               Exchange Act of 1934 (the "Exchange Act"), including any
               amendment or report filed for the purpose of updating such
               description.

        All documents filed by the Company pursuant to Sections 13(a), 13(c), 14

prior to the filing of a post-effective amendment which indicates that all
securities offered have been sold or which deregisters all securities then
remaining unsold, shall be deemed to be incorporated by reference in this

ITEM 4.  DESCRIPTION OF SECURITIES.

        Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

        Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        Section 145 of the Delaware General Corporations Law authorizes a court

reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended (the "Securities Act"). Article VI of the Company's Bylaws provides
for the mandatory indemnification of its directors, officers, employees and

Law, and the Company has entered into agreements with its officers, directors
and certain key employees implementing such indemnification.

        Exhibit Number

               5.1           Opinion of Wilson Sonsini Goodrich & Rosati, P.C.,
                             as to the legality of securities being registered.

               10.1          1993 Employee Stock Purchase Plan, as amended

               10.2          1995 Long-Term Incentive Plan, as amended

               23.1          Consent of Price Waterhouse LLP

               23.2          Consent of Counsel (included in Exhibit 5.1)

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 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,

               (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.

               (4) 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.

                      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 Registrant's Bylaws,
indemnification agreements, 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 adjudication of such issue.

(1)  Estimated pursuant to Rule 457 of Regulation C solely for the purpose of
     calculating the registration fee. The proposed maximum offering price per
     share with respect to the additional 200,000 shares recently authorized and
     reserved for issuance under the 1993 Employee Stock Purchase Plan has been
     estimated to be 85% of the average of the high and low prices reported in
     the Nasdaq National Market on June 22, 1998.

(2)  Estimated pursuant to Rule 457 of Regulation C solely for the purpose of
     calculating the registration fee. The proposed maximum offering price per
     share with respect to the 500,000 shares authorized and reserved for
     issuance under the 1995 Long-Term Incentive Plan has been estimated to be
     the average of the high and low prices reported in the Nasdaq National
     Market on June 22, 1998.

(3)  Amount of Registration Fee was calculated pursuant to Section 6(b) of the
     Securities Act of 1933, which states that the fee shall be "$295 per $1
     million " of the maximum aggregate price at which such securities are
     proposed to be offered. The Registration Fees are therefore calculated by
     multiplying the aggregate offering or sales amount by 0.000295.

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3. INFORMATION INCORPORATED BY REFERENCE.

        There are hereby incorporated by reference in this Registration
Statement the following documents and information heretofore filed with the
Securities and Exchange Commission (the "SEC"):

        (a)    The Company's Annual Report on Form 10-K filed with the SEC for
               the year ended December 31, 1997.

        (b)    The Company's Quarterly Report on Form 10-Q filed with the SEC

        (c)    The description of the Registrant's Common Stock to be offered
               hereby is contained in the Registrant's Registration Statement on
               Form 8-A filed with the Securities and Exchange Commission on
               October 21, 1993 pursuant to Section 12(g) of the Securities
               Exchange Act of 1934 (the "Exchange Act"), including any
               amendment or report filed for the purpose of updating such
               description.

        All documents filed by the Company pursuant to Sections 13(a), 13(c), 14
and 15(d) of the Exchange Act after the date of this Registration Statement and
prior to the filing of a post-effective amendment which indicates that all

ITEM 4.  DESCRIPTION OF SECURITIES.

        Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

        Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        Section 145 of the Delaware General Corporations Law authorizes a court

indemnification under certain conditions for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended (the "Securities Act"). Article VI of the Company's Bylaws provides
for the mandatory indemnification of its directors, officers, employees and

Law, and the Company has entered into agreements with its officers, directors
and certain key employees implementing such indemnification.

               5.1           Opinion of Wilson Sonsini Goodrich & Rosati, P.C.,
                             as to the legality of securities being registered.

               10.1          1993 Employee Stock Purchase Plan, as amended

               10.2          1995 Long-Term Incentive Plan, as amended

               23.1          Consent of Price Waterhouse LLP

               23.2          Consent of Counsel (included in Exhibit 5.1)

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 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,

               (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.

               (4) 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.

                      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 Registrant's Bylaws,
indemnification agreements, 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 adjudication of such issue.
