<U>Indemnification of Directors and Officers</U>
</DIV>
<DIV align="left" style="font-size: 10pt; margin-top: 6pt">Section&nbsp;145 of the Delaware General Corporation Law authorizes a court to award or a corporation&#146;s
board of directors to grant indemnification to directors and officers in terms sufficiently broad
to permit such indemnification under certain circumstances for liabilities (including reimbursement
for expenses incurred) arising under the Securities Act of 1933 (&#147;1933 Act&#148;). The Registrant&#146;s
Certificate of Incorporation provides that, pursuant to Delaware law, its directors shall not be
liable for monetary damages for breach of their fiduciary duty as directors to the Registrant and
its stockholders. This provision in the Certificate of Incorporation does not eliminate the
fiduciary duty of the directors, and, in appropriate circumstances, equitable remedies such as
injunctive or other forms of non-monetary relief will remain available under Delaware law. In
addition, each director will continue to be subject to liability for breach of the director&#146;s duty
of loyalty to the Registrant for acts or omissions not in good faith or involving intentional
misconduct, for knowing violations of law, for actions leading to improper personal benefit to the
director and for payment of dividends or approval of stock repurchases or redemptions that are
unlawful under Delaware law. The provision also does not affect a director&#146;s responsibilities under
any other law, such as the federal securities laws or state or federal environmental laws. The
Registrant has entered into Indemnification Agreements with its officers and directors. The
Indemnification Agreements provide the Registrant&#146;s officers and directors with further
indemnification to the maximum extent permitted by the Delaware General Corporation Law.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">A. The undersigned Registrant hereby undertakes: (1)&nbsp;to file, during any period in which offers or
sales are being made, a post-effective amendment to this Registration Statement (i)&nbsp;to include any
prospectus required by Section&nbsp;10(a)(3) of the 1933 Act, (ii)&nbsp;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 and (iii)&nbsp;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 clauses (1)(i) and (1)(ii) shall 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 SEC by the Registrant pursuant to Section&nbsp;13 or Section 15(d) of the
1934 Act that are incorporated by reference in this Registration Statement; (2)&nbsp;that for the
purpose of determining any liability under the 1933 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 and (3)&nbsp;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 Registrant&#146;s Amended and
Restated 1998 Equity Incentive Plan and 1998 Employee Stock Purchase Plan.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">B. The undersigned Registrant hereby undertakes that, for purposes of determining any liability
under the 1933 Act, each filing of the Registrant&#146;s annual report pursuant to Section 13(a) or
Section 15(d) of the 1934 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.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">C. Insofar as indemnification for liabilities arising under the 1933 Act may be permitted to
directors, officers or controlling persons of the Registrant pursuant to the indemnification
provisions summarized in Item&nbsp;6 or otherwise, the Registrant has been advised that, in the opinion
of the SEC, such indemnification is against public policy as expressed in the 1933 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 1933 Act and will be governed by
the final adjudication of such issue.

</DIV>
<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We have acted as counsel to Actuate Corporation, a Delaware corporation (the &#147;Company&#148;), in
connection with the registration on Form S-8 (the &#147;Registration Statement&#148;) under the Securities
Act of 1933, as amended, of: (i)&nbsp;an additional 2,800,000 shares of the Company&#146;s common stock
reserved for issuance under the Company&#146;s Amended and Restated 1998 Equity Incentive Plan (the
&#147;Incentive Plan&#148;) and (ii)&nbsp;an additional 600,000 shares of the Company&#146;s common stock reserved for
issuance under the Company&#146;s 1998 Employee Stock Purchase Plan (the &#147;Purchase Plan&#148;). All such
shares are collectively referred to herein as the &#147;Shares&#148;.

601(b)(5)(i) of Regulation&nbsp;S-K.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">We have
reviewed the Company&#146;s charter documents together with the
applicable Purchase Plan and Incentive Plan documents (including the
automatic share increase provisions) and the corporate proceedings taken by the Company
in connection with respect to the establishment and the amendment of the Incentive Plan and the
Purchase Plan. Based on such review, we are of the opinion that, if, as and when the Shares have
been issued and sold (and the consideration therefore received) pursuant to (a)&nbsp;duly authorized
option agreements under the Incentive Plan and in accordance with the Registration Statement, (b)
duly authorized restricted stock units or other stock-based awards under the Incentive Plan and in
accordance with the Registration Statement, or (c)&nbsp;duly authorized stock purchase agreements under
the Purchase Plan and in accordance with the Registration Statement, such Shares will be duly
authorized, legally issued, fully paid and nonassessable.

giving the opinion set forth in this letter, we do not hereby admit that we are acting within the
category of persons whose consent is required under Section&nbsp;7 of the Securities Act of 1933, as
amended, or the rules or regulations of the Securities and Exchange Commission thereunder.
