<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We are
a biopharmaceutical company exploiting proprietary RNA-based drug discovery
technologies to identify and commercialize novel drugs to treat important
diseases. RNA, or ribonucleic acid, is a molecule that provides to a cell the
information the cell needs to produce proteins, including those proteins
implicated in disease. Interference with RNA can keep the body from producing
proteins that are involved in disease. We are the leader in exploiting RNA as a
target for drugs, and have a strong proprietary position in RNA-based drug
discovery technologies. With our primary technology, antisense, we create
inhibitors, or oligonucleotides, designed to hybridize, with a high degree of
specificity to their RNA target and modulate the production of specific
proteins associated with disease. We also use our antisense technology
internally and in collaborations with pharmaceutical companies to rapidly and
efficiently identify and prioritize attractive gene targets for drug
discovery.&#160; Within our Ibis division, we
are expanding on our RNA expertise by creating a system that can rapidly and
accurately identify a broad range of infectious organisms with a single
test.&#160; Our ongoing development of this
technology and a system related to this technology has been funded primarily by
agencies within the United States government.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We successfully commercialized our first antisense
drug, Vitravene. Vitravene demonstrates our ability to meet Food and Drug
Administration, or FDA, and European regulatory requirements, and to
commercially manufacture antisense drugs. We and our partners currently have 10
antisense products in preclinical and clinical development, the majority of
which are in Phase I or Phase II human clinical trials. Our products in
development address numerous therapeutic areas with major market potential,
including inflammatory, metabolic and cardiovascular diseases, and cancer. We
are expanding the therapeutic opportunities for antisense drugs by developing a
variety of formulations to enhance patient convenience and compliance. In
addition, our pipeline has matured to consist primarily of drugs based on our
proprietary second-generation chemistry.&#160;
Our second-generation antisense drugs offer a number of advantages over
prior chemistries.&#160; Specifically, these
drugs offer the potential for improved safety, increased potency and a longer
half-life, which correlates with durability of therapeutic response and the
potential for less frequent dosing.&#160;
Physicians may be able to dose our second-generation drugs as
infrequently as once every two weeks to once a month. We are also making
progress on developing oral formulations of our second-generation antisense
drugs.&#160; Our oral formulations may
increase the commercial value of our antisense drugs.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Within our Ibis division we have invented technology
that has the potential to revolutionize the identification of infectious
diseases.&#160; This technology is called
Triangulation Identification for Genetic Evaluation of Risks, or TIGER.&#160; We have applied the TIGER technology to
develop a system to identify from a sample a broad range of infectious
organisms, including organisms that are newly-emerging, genetically altered and
unculturable.&#160; We have successfully
demonstrated proof-of-principle of the TIGER system with the identification of
a variety of bacteria and viruses in both environmental and human clinical
samples. During 2004, we advanced the development of our TIGER system to
include application development for epidemiological surveillance and biological
products screening. These applications represent the first of many we plan to
develop to enhance the TIGER system&#146;s commercial value and opportunity in the
government, research, medical and diagnostic markets.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Because drug discovery
and development require substantial lead-time and money prior to
commercialization, our expenses have exceeded our revenue since we were founded
in January&nbsp;1989. As of June&nbsp;30, 2005, we had accumulated losses of
approximately $747.8 million and a stockholders&#146; deficit of approximately
$124.2 million.&#160; Most of the losses
resulted from costs incurred in connection with our research and development
programs and from general and administrative costs associated with our operations.
Most of our revenue has come from collaborative arrangements, with additional
revenue from interest income and research grants and the sale or licensing of
patents. We currently have only one product, Vitravene, approved for commercial
use.&#160; This product has limited sales
potential. We expect to incur additional operating losses over the next several
years, and these losses may increase if we cannot increase or sustain revenue.
We may not successfully develop any additional products or services, or achieve

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We and our partners must
conduct time-consuming, extensive and costly clinical trials to show the safety
and efficacy of each of our drug candidates before a drug candidate can be
approved for sale. We must conduct these trials in compliance with United
States Food and Drug Administration regulations and with comparable regulations
in other countries. If the FDA or another regulatory agency believes that we or
our partners have not sufficiently demonstrated the safety or efficacy of our
drug candidates, it will not approve them or will require additional studies,
which can be time consuming and expensive and which will delay
commercialization of a drug candidate. We and our partners may not be able to
obtain necessary regulatory approvals on a timely basis, if at all, for any of
our drug candidates. Failure to receive these approvals or delays in these
approvals could prevent or delay commercial introduction of a product and, as a
result, could negatively impact our ability to generate revenue from product
sales. In addition, following approval of a drug candidate, we and our partners
must comply with comprehensive government regulations regarding how we
manufacture, market and distribute products. If we fail to comply with these
regulations, regulators could force us to withdraw a drug candidate from the
market or impose other penalties or requirements that also could have a
negative impact on our financial results.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Drug discovery and
development has inherent risks, including the risk that molecular targets prove
not to be important in a particular disease; the risk that compounds that
demonstrate attractive activity in preclinical studies do not demonstrate
similar activity in human beings; the risk that a compound is not safe or
effective for use in humans; and the risk that successful results in early
human clinical trials may not be indicative of results in late-stage clinical
trials. Antisense technology in particular is relatively new and unproven. We
are applying most of our resources to create safe and effective drugs for human
use. Any of the risks described above could prevent us from meeting this goal.&#160; In the past, we have invested in clinical
studies of drug candidates that have not met the primary clinical end points in
their initial Phase III studies.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">If we need additional
funds, we may need to raise them through public or private financing.
Additional financing may not be available at all or on acceptable terms. If we
raise additional funds by issuing equity securities, the shares of existing
stockholders will be diluted and their price, as well as the price of our other
securities, may decline. If adequate funds are not available, we may have to
cut back on one or more of our research, drug discovery or development
programs.&#160; For example, in
January&nbsp;2005 we decided to terminate the development of two lower priority
drugs, ISIS 14803 and ISIS 104838.&#160;
Alternatively, we may obtain funds through arrangements with
collaborative partners or others, which could require us to give up rights to
certain of our technologies, product candidates or products.</font></p>

<p style="margin:0in 0in .0001pt;"><b><font size="2" face="Times New Roman" style="font-size:10.0pt;font-weight:bold;">If we cannot manufacture our
products or contract with a third party to manufacture our products at costs
that allow us to charge competitive prices to buyers, we will not be able to
market products profitably.</font></b></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">If we successfully
commercialize any of our drug candidates, we may be required to establish
large-scale commercial manufacturing capabilities. In addition, as our drug
development pipeline increases and matures, we will have a greater need for
clinical trial and commercial manufacturing capacity. We have limited
experience manufacturing pharmaceutical products of the chemical class
represented by our drug candidates, called oligonucleotides, on a commercial
scale for the systemic administration of a drug. There are a small number of
suppliers for certain capital equipment and raw materials that we use to
manufacture our drugs, and some of these suppliers will need to increase their
scale of production to meet our projected needs for commercial manufacturing.
Further, we must continue to improve our manufacturing processes to allow us to
reduce our product costs. We may not be able to manufacture at a cost or in
quantities necessary to make commercially successful products.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Also, manufacturers,
including us, must adhere to the FDA&#146;s current Good Manufacturing Practices
regulations which the FDA enforces through its facilities inspection program.
We and our contract manufacturers may not be able to comply or maintain
compliance with Good Manufacturing Practices regulations. Non-compliance could
significantly delay our receipt of marketing approval for potential products or
result in FDA enforcement action after approval that could limit the commercial
success of our potential product.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our competitors are
engaged in all areas of drug discovery throughout the world, are numerous, and
include, among others, major pharmaceutical companies and specialized
biopharmaceutical firms. Other companies are engaged in developing antisense
technology or unique methods of identifying infectious organisms. Our
competitors may succeed in developing drug candidates or technologies that are
more effective than any drug candidates or technologies that we are developing.
These competitive developments could make our products obsolete or
non-competitive.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Many of our competitors
have substantially greater financial, technical and human resources than we do.
In addition, many of these competitors have significantly greater experience
than we do in conducting preclinical testing and human clinical trials of new
pharmaceutical products and in obtaining FDA and other regulatory approvals of
products for use in health care. Accordingly, our competitors may succeed in
obtaining regulatory approval for products earlier than we do. We will also
compete with respect to marketing and sales capabilities, areas in which we
have limited or no experience.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><b><font size="2" face="Times New Roman" style="font-size:10.0pt;font-weight:bold;">If we cannot protect our patents

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our success depends to a
significant degree upon our ability to continue to develop and secure
intellectual property rights to proprietary products and services. However, we
may not receive issued patents on any of our pending patent applications in the
United States or in other countries. In addition, the scope of any of our
issued patents may not be sufficiently broad to provide us with a competitive
advantage. Furthermore, our issued patents or patents licensed to us may be
successfully challenged, invalidated or circumvented so that our patent rights
would not create an effective competitive barrier or revenue source.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">If a third party claims
that our products or technology infringe their patents or other intellectual
property rights, we may have to discontinue an important product or product
line, alter our products and processes, pay license fees or cease certain
activities. We may not be able to obtain a license to such intellectual
property on favorable terms, if at all. There are many patents issued or
applied for in the biotechnology industry, and we may not be aware of patents
or applications held by others that relate to our business. This is especially
true since patent applications in the United States are filed confidentially.
Moreover, the validity and breadth of biotechnology patents involve complex
legal and factual questions for which important legal issues remain unresolved.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">For planning purposes, we
estimate the timing of a variety of clinical, regulatory and other milestones,
like when a certain product candidate will enter the clinic, when we will
complete a clinical trial, or when we will file an application for marketing
approval. We base our estimates on present facts and a variety of assumptions.
Many of the underlying assumptions are outside of our control. If we do not
achieve milestones when we expect to, investors could be disappointed and the
price of our securities would likely decrease.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We are dependent on the
principal members of our management and scientific staff. We do not have
employment agreements with any of our executive officers. The loss of our
management and key scientific employees might slow the achievement of important
research and development goals. It is also critical to our success that we recruit
and retain qualified scientific personnel to perform research and development
work. We may not be able to attract and retain skilled and experienced
scientific personnel on acceptable terms because of intense competition for
experienced scientists among many pharmaceutical and health care companies,
universities and non-profit research institutions. Failure to succeed in
clinical trials may make it more challenging to recruit and retain qualified
scientific personnel.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We depend on independent
clinical investigators, contract research organizations and other third party
service providers in the conduct of our clinical trials for our product
candidates and expect to continue to do so in the future. We rely heavily on
these parties for successful execution of our clinical trials, but do not
control many aspects of their activities. For example, the investigators are
not our employees. However, we are responsible for ensuring that each of our
clinical trials is conducted in accordance with the general investigational
plan and protocols for the trial. Third parties may not complete activities on
schedule, or may not conduct our clinical trials in accordance with regulatory
requirements or our stated protocols. The failure of these third parties to
carry out their obligations could delay or prevent the development, approval
and commercialization of our product candidates.</font></p>

common stock, like that of the securities of many other biopharmaceutical
companies, has been and is likely to continue to be highly volatile. These
fluctuations in our common stock price may significantly affect the trading price
of our securities. During the 12 months preceding June&nbsp;30, 2005, the
market price of our common stock has ranged from $2.76 to $6.67 per share.&#160; Many factors can affect the market price of
our securities, including, for example, fluctuations in our operating results,
announcements of collaborations, clinical trial results, technological
innovations or new drug products being developed by us or our competitors,
governmental regulation, regulatory approval, developments in patent or other
proprietary rights, public concern regarding the safety of our drugs and
general market conditions.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Our certificate of
incorporation also requires that any action required or permitted to be taken
by our stockholders must be taken at a duly called annual or special meeting of
stockholders and may not be taken by written consent. In addition, only our
board of directors, chairman of the board or chief executive officer can call
special meetings of our stockholders. We also have implemented a stockholders&#146;
rights plan, also called a poison pill, which could make it uneconomical for a
third party to acquire our company on a hostile basis. These provisions, as
well as Delaware law and other of our agreements, may discourage certain types
of transactions in which our stockholders might otherwise receive a premium for
their shares over then current market prices, and may limit the ability of our
stockholders to approve transactions that they think may be in their best
interests. In addition, our board of directors has the authority to fix the
rights and preferences of and issue shares of preferred stock, which may have the
effect of delaying or preventing a change in control of our company without
action by our stockholders.</font></p>

stock offered by this prospectus or interests therein from time to time on The
Nasdaq National Market, in privately negotiated transactions or otherwise. We

statement effective for the period of time required under our agreements with
the selling stockholders. &#160;The warrants held

the rules of the Securities and Exchange Commission, or SEC and is based upon
information provided by each respective selling stockholder, Schedules 13D and
13G and other public documents filed with the SEC. Although the warrants held
by the selling stockholders are not exercisable until February 19, 2006, the
shares of common stock issuable upon exercise of the warrants held by the
selling stockholders are included in the table below since those shares of
common stock are being offered in this prospectus. The percentages of shares
owned after the offering are based on 72,202,052 shares of our common stock
outstanding as of August 25, 2005, which includes the outstanding shares of
common stock offered by this prospectus but excludes all warrant shares since
the related warrants are not currently exercisable and are not exercisable
within 60 days from the date hereof.</font></p>

stockholder may offer shares for sale or other disposition. The selling
stockholders might not sell or dispose of any or all of the shares offered by
this prospectus. Because the selling stockholders may offer all or some of the
shares pursuant to this offering, and because there are currently no
agreements, arrangements or understandings with respect to the sale of any of
the shares, we cannot estimate the number of the shares that will be held by
the selling stockholders after completion of the offering. However, for

none of the shares covered by this prospectus will be held by the selling
stockholders.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Under Section 145 of the
Delaware General Corporation Law, the Registrant 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.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Registrant&#146;s
Certificate of Incorporation and Bylaws 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 (the &#147;Delaware Law&#148;) and (ii)
require the Registrant 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.&#160; 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.&#160; The Registrant believes that
these provisions are necessary to attract and retain qualified persons as
Directors and officers.&#160; These provisions
do not eliminate the Directors&#146; 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.&#160; In addition, each Director will continue to
be subject to liability for breach of the Directors&#146; duty of loyalty to the
Registrant, 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 Registrant 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&#146; duty to the Registrant or its stockholders when the Director was
aware or should have been aware of a risk of serious injury to the Registrant
or its stockholders, for acts or omissions that constitute an unexcused pattern
of inattention that amounts to an abdication of the Director&#146;s duty to the
Registrant or its stockholders, for improper transactions between the Director
and the Registrant and for improper distributions to stockholders and loans to
Directors and officers.&#160; The provision
also does not affect a Director&#146;s responsibilities under any other law, such as
the federal securities law or state or federal environmental laws.</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;text-indent:.5in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Registrant has
entered into indemnity agreements with each of its Directors and executive
officers that require the Registrant 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
Registrant 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 Registrant and, with respect to any
criminal proceeding, has no reasonable cause to believe his conduct was
unlawful.&#160; The indemnification agreements
also set forth certain procedures that will apply in the event of a claim for
indemnification thereunder.</font></p>

pending litigation or proceeding involving a Director or officer of the

indemnification by any officer or Director.</font></p>

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.</p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">You have requested my opinion with respect to certain matters in
connection with the filing by Isis Pharmaceuticals, Inc. (the &#147;Company&#148;) of a
Registration Statement on Form S-3 (the &#147;Registration Statement&#148;) with the
Securities and Exchange Commission, covering the registration of 14,999,998
shares of the Company&#146;s Common Stock for resale on behalf of a certain selling
stockholders, including 12,000,000 shares of Common Stock (the &#147;Shares&#148;) and up
to 2,999,998 shares of Common Stock (the &#147;Warrant Shares&#148;) issuable upon the
exercise of certain warrants held by such selling stockholders (the
&#147;Warrants&#148;).</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">In connection with this opinion, I have examined and relied upon the
Registration Statement and related Prospectus, the Warrants, the Company&#146;s
Certificate of Incorporation and Bylaws, as amended, and the originals or
copies certified to my satisfaction, of such records, documents, certificates,
memoranda and other instruments as in my judgment are necessary or appropriate
to enable me to render the opinion expressed below.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On the basis of the foregoing, and in reliance thereon, I am of the
opinion that (i) the Shares are validly issued, fully paid and nonassessable,
and (ii) the Warrant Shares, when issued and sold in accordance with the terms
of the Warrants, will be validly issued, fully paid and nonassessable.</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman">&nbsp;</font></p>

<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">I consent to the reference to myself under the caption &#147;Legal Matters&#148;
