public policy as expressed in the Securities Act and is, therefore,
unenforceable.&#160; 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 of
whether such indemnification by it is against public policy as expressed in the
Act and will be governed by a final adjudication of such issue.</p>

Item 6.
Indemnification of Directors and Officers.
Quidel is a Delaware
corporation.  Section 145(a) of
the General Corporation Law of the State of Delaware (the "DGCL") provides that
a Delaware corporation may 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 such person 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 enterprise, against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person 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 cause to believe his or
her conduct was unlawful.
Section 145(b) of
the DGCL provides that a Delaware corporation may 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 a corporation to procure a
judgment in its favor by reason of the fact that such person acted in any of
the capacities set forth above, against expenses (including attorneys' fees)
actually and reasonably incurred by such person in connection with the defense
or settlement of such action or suit if he or she acted under similar standards
to those set forth above, except that no indemnification may be made in respect
to any claim, issue or matter as to which such person shall have been adjudged
to be liable to the corporation unless and only to the extent that the Chancery
Court or court in which such action or suit was brought shall determine that
despite the adjudication of liability, but in view of all the circumstances of
the case, such person is fairly and reasonably entitled to be indemnified for
such expenses which the Court of Chancery or such other court shall deem
proper.
Further subsections of
DGCL Section 145 provide that:
(1)  to the
extent a present or former director or officer of a corporation has been successful
on the merits or otherwise in the 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, such person shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred
by such person in connection therewith;
(2)  any
indemnification under subsections (a) and (b) of Section 145
(unless ordered by a court) shall be made by the corporation only as authorized
in the specific case upon a determination that indemnification of the present
or former director, officer, employee or agent is proper in the circumstances
because the person has met the applicable standard of conduct set forth in
subsections (a) and (b) of Section 145. Such determination shall
be made, with respect to a person who is a director or officer at the time of
such determination, (1) by a majority vote of the directors who are not
parties to such action, suit or proceeding, even though less than a quorum, or (2) by
a committee of such directors designated by majority vote of such directors,
even though less than a quorum, or (3) if there are no such directors, or
if such directors so direct, by independent legal counsel in a written opinion,
or (4) by the stockholders;
(3)  expenses
(including attorneys' fees) incurred by an officer or director in defending any
civil, criminal, administrative or investigative action, suit or proceeding may
be paid by the corporation in advance of the final disposition of such action,
suit or proceeding upon receipt of an undertaking by or on behalf of such
director or officer to repay such amount if it shall ultimately be determined
that such person is not entitled to be indemnified by the corporation as
authorized in Section 145. Such expenses (including attorneys' fees)
incurred by former directors and officers or other employees and agents may be
so paid upon such terms and conditions, if any, as the corporation deems
appropriate;
(4)  the
indemnification and advancement of expenses provided by, or granted pursuant
to, Section 145 shall not be deemed exclusive of any other rights to which
those seeking indemnification or advancement of expenses may be entitled under
any bylaw, agreement, vote of stockholder or disinterested directors or
otherwise, both as to action in such person's official capacity and as to
action in another capacity while holding such office; and
(5)  the
corporation shall have the power 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 such
person and incurred by such person in any such capacity, or arising out of such
person's status as such, whether or not the corporation would have the power to
indemnify such person against such liability under Section 145.
Article 10 of
Company's Certificate of Incorporation relieves its directors from monetary
damages to the Company or its stockholders for breach of such director's
fiduciary duty as a director to the fullest extent permitted by the DGCL. Under
Section 102(b)(7) of the DGCL, a corporation may relieve its
directors from personal liability to such corporation or its stockholders for
monetary damages for any breach of their fiduciary duty as directors except (i) for
a breach of the duty of loyalty, (ii) for failure to act
3
in good faith, (iii) for
intentional misconduct or knowing violation of law, (iv) for willful or
negligent violations of certain provisions in the DGCL imposing certain
requirements with respect to stock repurchases, redemptions and dividends, or (v) for
any transactions from which the director derived an improper personal
benefit.  Depending upon the character of
the proceeding, under Delaware law, the Company may indemnify against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred in connection with any action, suit or
proceeding if the person indemnified acted in good faith and in a manner he or
she reasonably believed to be in or not opposed to the best interest of the
Company.
The Company's Bylaws
provide that the Company shall indemnify, in the manner and to the fullest
extent permitted by the DGCL, 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 or not by or in the right of the Company, by reason
of the fact that he is or was a director of officer of the Company, or is or
was serving at the request of the Company as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise.
To implement the
provisions of the DGCL and our Bylaws, we enter into indemnification agreements
with each of our directors and officers. 
The provisions of the indemnification agreements parallel the portions
of our Bylaws described above and generally provide indemnification to the
fullest extent permitted by the DGCL. 
Absent the Indemnification Agreements, the indemnification that might be
available to directors and officers could be changed by amendment to our
Certificate of Incorporation and Bylaws. 
In the event of changes, after the date of such Indemnification
Agreements, in any applicable law, statute or rule which expands the right
of a Delaware corporation to indemnify a member of its board of directors or an
officer, such changes shall be,
ipso facto
,
within the purview of the rights and obligations under the Indemnification
Agreements.  We may seek directors and
officers liability insurance against the cost of defense, settlement or payment
of a judgment under certain circumstances.

(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;
(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 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 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 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)
Insofar as
indemnification for liabilities arising under the Securities Act maybe
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 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 of
whether such indemnification by it is against public policy as expressed in the
Act and will be governed by a final adjudication of such issue.
