(1) Includes 1,990,000 shares issuable pursuant to the Registrant's 2000 Broad Based Equity Incentive Plan (the "Equity Plan") and 200,000 shares issuable pursuant to the Registrant's 2000 Employee Stock Purchase Plan (the "ESPP"). (2) Estimated solely for the purpose of calculating the amount of the registration fee pursuant to Rule 457(h)(1) of the Securities Act of 1933, as amended, (the "Securities Act"). The price per share and the aggregate offering price are calculated on the basis of (a) the weighted average of $6.9766, the exercise price for 1,859,954 shares subject to outstanding options granted under the Equity Plan and (b) $12.90625, the average of the high and low sales prices of Registrant's Common Stock on June 23, 2000, as reported on the NASDAQ National Market for the remainder of the shares subject to the Equity Plan registered hereunder, as well as the shares subject to the ESPP. INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE The following documents filed by ISIS PHARMACEUTICALS, INC. (the "Company") with the Securities and Exchange Commission are incorporated by reference into this Registration Statement: (a) The Company's latest annual report on Form 10-K filed pursuant to Section 13(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act").

(c) The description of the Company's Common Stock which is contained in a registration statement filed under the Exchange Act, including any amendment or report filed for the purpose of updating such description. All reports and other documents subsequently filed by the Company pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act 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 herein and to be a part of this registration statement from the date of the filing of such reports and documents. 3 DESCRIPTION OF SECURITIES Not applicable. INTERESTS OF NAMED EXPERTS AND COUNSEL The validity of the issuance of the common stock offered in this prospectus will be passed upon for Isis by Grantland E. Bryce, Vice President and General Counsel of Isis. Mr. Bryce is the beneficial owner of options to purchase 81,500 shares of Isis common stock. As of August 1, 2000 Mr. Bryce will be vested as to options to purchase 24,106 shares of Isis common stock. INDEMNIFICATION OF DIRECTORS AND OFFICERS Under Section 145 of the Delaware General Corporation Law, the Company has broad powers to indemnify its directors and officers against liabilities they may incur in such capacities, including liabilities under the Securities Act of 1933. The Company's certificate of incorporation and by-laws include provisions to (i) eliminate the personal liability of its directors for monetary damages resulting from breaches of their fiduciary duty to the extent permitted by Section 102(b)(7) of the General Corporation Law of Delaware and (ii) require the Company to indemnify its directors and officers to the fullest extent permitted by Section 145 of the Delaware Law, including circumstances in which indemnification is otherwise discretionary. Pursuant to Section 145 of the Delaware Law, a corporation generally has the power to indemnify its present and former directors, officers, employees and agents against expenses incurred by them in connection with any suit to which they are, or are threatened to be made, a party by reason of their serving in such positions so long as they acted in good faith and in a manner they reasonably believed to be in, or not opposed to, the best interest of the corporation, and with respect to any criminal action, they had no reasonable cause to believe their conduct was unlawful. The Company believes that these provisions are necessary to attract and retain qualified persons as directors and officers. These provisions do not eliminate the directors' duty of care, 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 directors' duty of loyalty to the Company, for acts or omissions not in good faith or involving intentional misconduct, for knowing violations of law, for acts or omissions that the director believes to be contrary to the best interests of the Company or its stockholders, for any transaction from which the director derived an improper personal benefit, for acts or omissions involving a reckless disregard for the directors' duty to Isis or its stockholders when the director was aware or should have been aware of a risk of serious injury to the Company or its stockholders, for acts or omissions that constitute an unexcused pattern of inattention that amounts to an abdication of the director's duty to the Company or its stockholders, for improper transactions between the director and the Company and for improper distributions to stockholders and loans to directors and officers. The provision also does not affect a director's responsibilities under any other law, such as the federal securities law or state or federal environmental laws. The Company has entered into indemnity agreements with each of its directors and executive officers that require the Company to indemnify such persons against expenses, judgments, fines, settlements and other amounts incurred (including expenses of a derivative action) in connection with any proceeding, whether actual or threatened, to which any such person may be made a party by reason of the fact that such person is or was a director or an executive officer of the Company or any of its affiliated enterprises, provided such person acted in good faith and in a manner such persons reasonably believed to be in, or not opposed to, the best interests of the Company and, with respect to any criminal proceeding, has no reasonable cause to believe his conduct was unlawful. The indemnification agreements also set forth procedures that will apply in the event of a claim for indemnification thereunder. The Company has an insurance policy covering the officers and directors of the Company with respect to certain liabilities, including liabilities arising under the Securities Act or otherwise. 4 EXHIBITS

* Filed as an exhibit to the Registrant's Annual Report on Form 10-K for the year ended December 31, 1999, and incorporated herein by reference. 5 UNDERTAKINGS 1. The undersigned registrant hereby undertakes: (a) 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; (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) (Section 230.424(b) of this chapter) if, in the aggregate, the changes in volume and price represent no more than a 20% 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)(i) and (a)(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 by the issuer pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference herein. (b) 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 herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) 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. 2. 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 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 herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. 3. Insofar as indemnification for liabilities arising under the Securities Act 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 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. 6 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Carlsbad, State of California, on June 28, 2000.

Ladies and Gentlemen:

You have requested my opinion with respect to certain matters in connection with
the filing by Isis Pharmaceuticals, Inc. (the "Company") of a Registration
Statement on Form S-8 (the "Registration Statement") with the Securities and
Exchange Commission, covering the offering of an aggregate of 2,190,000 shares
of the Company's Common Stock, $.001 par value (the "Shares"), including (i)
1,990,000 shares issuable pursuant to its 2000 Broad Based Equity Incentive Plan
(the "Equity Plan") and (ii) 200,000 shares issuable pursuant to its 2000
Employee Stock Purchase Plan (the "ESPP"), as described in the Registration
Statement.

In connection with this opinion, I have examined and relied upon the
Registration Statement, the Company's Amended and Restated Certificate of
Incorporation and Bylaws and the originals or copies certified to my
satisfaction, of such records, documents, certificates, memoranda and other

render the opinion expressed below.

On the basis of the foregoing, and in reliance thereon, I am of the opinion that
the Shares, when issued and sold in accordance with the Equity Plan or the ESPP,
as applicable, the Registration Statement and related prospectus, will be
validly issued, fully paid and nonassessable.

I consent to the reference to myself under the caption "Interests of Named
Experts and Counsel" in the Registration Statement and to the filing of this
