later information filed with the SEC will update and supersede this information. We incorporate by

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are subject to Section&nbsp;145 of the Delaware General Corporation Law (&#147;Section&nbsp;145&#148;). Section
145 permits indemnification of officers and directors of the Company under certain conditions and
subject to certain limitations. Section&nbsp;145 also provides that a corporation has the power to
maintain insurance on behalf of our officers and directors against any liability asserted against
such person and incurred by him or her in 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
liability under the provisions of Section&nbsp;145.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Article&nbsp;VI, Section&nbsp;6.1, of our Bylaws provides for mandatory indemnification of our directors
and officers and permissible indemnification of employees and other agents to the maximum extent
not prohibited by the Delaware General Corporation Law. The rights to indemnity thereunder continue
as to a person who has ceased to be a director, officer, employee or agent and inure to the benefit
of the heirs, executors and administrators of the person. In addition, expenses incurred by a
director or executive officer in defending any civil, criminal, administrative or investigative
action, suit or proceeding by reason of the fact that he or she is or was a director or officer of
(or was serving at our request as a director or officer of another corporation) shall be paid by us
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 he or she is not entitled to be indemnified by us as authorized by the relevant
section of the Delaware General Corporation Law.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As permitted by Section&nbsp;102(b)(7) of the Delaware General Corporation Law, our Certificate of
Incorporation provides that, pursuant to Delaware law, our directors shall not be personally liable
for monetary damages for breach of the directors&#146; fiduciary duty as directors to us and our
stockholders. This provision in the Certificate of Incorporation does not eliminate the directors&#146;
fiduciary duty, 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 for acts or
omission not in good faith or involving international 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 Section&nbsp;174 of the Delaware
General Corporation 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.



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have entered into indemnification agreements with each of our directors and executive
officers. Generally, the indemnification agreements attempt to provide the maximum protection
permitted by Delaware law as it may be amended from time to time. Moreover, the indemnification
agreements provide for certain additional indemnification. Under such additional indemnification
provisions, however, an individual will not receive indemnification for judgments, settlements or
expenses if he or she is found liable to us (except to the extent the court determines he or she is
fairly and reasonably entitled to indemnity for expenses), for settlements not approved by us or
for settlements and expenses if the settlement is not approved by the court. The indemnification
agreements provide for us to advance to the individual any and all reasonable expenses (including
legal fees and expenses) incurred in investigating or defending any such action, suit or
proceeding. In order to receive an advance of expenses, the individual must submit to us copies of
invoices presented to him or her for such expenses. Also, the individual must repay such advances
upon a final judicial decision that he or she is not entitled to indemnification. We also maintain
directors&#146; and officers&#146; liability insurance.

to Section 13(a) or Section 15(d) of the Exchange Act of 1934 (and, where applicable, each filing
of an employee benefit plan&#146;s annual report pursuant to Section 15(d) of the Exchange Act of 1934)

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;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
indemnification provisions summarized in Item&nbsp;6 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 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.

                  Re: Illumina, Inc. Registration Statement on Form S-8 for
                  1,500,000 Shares of Common Stock Issuable Under the 2000 Stock
                  Plan, as Amended and 1,143,621 Shares of Common Stock Under
                  the 2000 Employee Stock Purchase Plan.

Ladies and Gentlemen:

      We have examined the Registration Statement on Form S-8 (the "Registration
Statement") filed by you with the Securities and Exchange Commission (the
"Commission") on April 13, 2005 in connection with the registration under the
Securities Act of 1933, as amended, of a total of 1,500,000 and 1,143,621 shares
of your Common Stock (the "Shares") reserved for issuance under your 2000 Stock
Plan, as amended and 2000 Employee Stock Purchase Plan, respectively. As your
counsel in connection with this transaction, we have examined the proceedings
taken and are familiar with the proceedings proposed to be taken by you in
connection with the sale and issuance of the Shares.

      It is our opinion that upon conclusion of the proceedings being taken or
contemplated by us, as your counsel, to be taken prior to the issuance of the
Shares, and upon completion of the proceedings being taken in order to permit
such transactions to be carried out in accordance with the securities laws of
the various states where required, the Shares when issued and sold in the manner
described in the Registration Statement will be legally and validly issued,
fully paid and non-assessable.

      We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to the use of our name wherever appearing in the
Registration Statement, including the Prospectus constituting a part thereof,
and in any amendment thereto.

                                                      Very truly yours,

                                                      /s/ HELLER EHRMAN LLP

                                                      HELLER EHRMAN LLP
