Privacy Policy

OUR PRIVACY COMMITMENT

Eisai Limited (“Eisai“) is committed to maintaining the accuracy, security and privacy of Personal Information in
accordance with applicable Canadian privacy laws. This policy applies to the collection, use of and disclosure of
Personal Information by Eisai Limited in Canada. This policy, and the website(s) on which this policy appears, is
intended for Canadian residents.

This Privacy Policy is a statement of principles and guidelines concerning the protection of Personal Information of
our customers, service providers and other individuals (“you“).

YOUR CONSENT

BY SUBMITTING PERSONAL INFORMATION TO EISAI OR ITS AGENTS AND SERVICE PROVIDERS, THROUGH ANY
MEANS, YOU AGREE THAT WE MAY COLLECT, USE AND DISCLOSE SUCH PERSONAL INFORMATION IN
ACCORDANCE WITH THIS PRIVACY POLICY AND AS PERMITTED OR REQUIRED BY APPLICABLE LAWS. Subject
to legal and contractual requirements, and reasonable notice, you may refuse or withdraw your consent to certain
of the identified purposes at any time by contacting Eisai's Privacy Officer using the contact information provided
below. If you refuse or withdraw your consent, we may not be able to provide you or continue to provide you with
certain services or information which may be of value to you.

If you provide us with the Personal Information of another individual, you represent that you have all necessary
authority and/or have obtained all necessary consents from such individual (or, if such individual is a minor in their
jurisdiction of residence, from their parent or legal guardian) to enable us to collect, use and disclose such Personal
Information for the purposes set forth in this Privacy Policy.

WHAT IS PERSONAL INFORMATION?

Canadian privacy laws define Personal Information broadly as information about an identifiable individual or as
information that allows an individual to be identified. For the purposes of this policy, Personal Information means
information about an identifiable individual, as may be defined from time to time in applicable privacy laws
(“Personal Information”). Personal Information includes personal health information which you provide to us or ask
others to provide to us.

WHAT PERSONAL INFORMATION DO WE COLLECT?

The types of Personal Information that Eisai may collect, use and disclose about you includes, (where applicable),
your name, address, telephone number and facsimile number, cellular telephone number, email address, date of
birth, insurance information, name of your physician, payment information, other contact information and possibly
information about your health. Some of our websites might require you to register in order to log in, in which case
you will be required to provide personal information about yourself to us. Typically, the information we ask for
includes some of the following, but this list is not exhaustive:

Contact details, such as your name and e-mail/postal address.

Basic information about you, such as age and gender.

Health and treatment data, including biometric information.

Other information may also be requested, when relevant, and could include information about lifestyle or the
household you live in as these impact aspects of managing medical conditions, or information regarding your
education and employment history if you are seeking a position with us.

Whenever we ask you for any Personal Information that can be used to identify you as an individual, we provide an
explanation as to why we gather the information, how we gather it, how we store it, and how we plan on treating
and using it.

Except as described in this Privacy Policy or as may be permitted or required by applicable law, we will only gather
Personal Information about you if you specifically agree to 'opt-in', i.e. you explicitly give us your consent to collect
this information regarding you.

We will only gather and store Personal Information for the purpose stated during the gathering process and for
such other purposes permitted or required by applicable law. When we finish processing your information for the
stated purpose, we will erase and destroy it, following any legal or Eisai retention periods, to help ensure your
privacy.

There is always a lot of information that a company can ask you for, but Eisai will only ask for information where
there is a clear and necessary need for that information, which is clearly and adequately explained to you.

WHY DO WE COLLECT YOUR PERSONAL INFORMATION?

Eisai limits the collection, use and disclosure of your Personal Information, both in the amount and type of Personal
Information, to that which is necessary to fulfill the purposes identified within this Privacy Policy or otherwise
disclosed to you. We will identify the purposes for which your Personal Information is collected at or before the
time your Personal Information is collected.

In general, Eisai collects, uses and discloses Personal Information in order to provide our customers with our

We disclose Personal Information in accordance with this Privacy Policy, or for the purpose(s) for which you have
given consent.

We keep your Personal Information, questions, and transactions with us confidential; and we employ the
appropriate security safeguards.

However, from time to time, Eisai may disclose your Personal Information to:

service providers, including an organization or individual retained by Eisai to perform functions on its behalf,
including, but not limited to, marketing, data processing, document management and office services;

service providers providing offsite servers to store information;

to entities within the Eisai Network of Companies to carry out the purposes indicated in this Privacy Policy;

a person who, in the reasonable judgment of Eisai, is providing or seeking the information as your agent;

any other third party or parties, where you consent to such disclosure or where disclosure is required or
permitted by law.

We reserve the right to transfer any Personal Information we have about you in the event that we merge with or
are acquired by a third party. We may also disclose your Personal Information to third parties if we have reason to
believe that disclosing such information is necessary to: (i) conduct investigations of possible breaches of law or
policies; (ii) identify, contact, or bring legal action against someone who may be violating an agreement they have
with us; (iii) to protect our rights, safety or property; or (iv) to investigate security breaches or cooperate with
government authorities pursuant to a legal matter.

Personal Information you provide to us may be transferred outside of your province of residence, and outside of
Canada, including to our offices in the U.S., the European Union, and/or Japan. You agree that by providing us with
your Personal Information, your Personal Information may be subject to the laws of such jurisdictions, regulations
and/or court orders and may be disclosed to third parties or authorities in complying with the laws, regulations
and/or court orders of such jurisdictions.

Further, please note that certain governmental agencies in jurisdictions where Eisai conducts business, such as the
United States, require pharmaceutical companies to disclose information on compensation, gifts or other
remuneration provided to physicians and other health care professionals. Eisai may report information about
remuneration provided as required. Once reported, such information may be publicly accessible, and your Personal
Information may be required to be disclosed. Under this privacy policy your Personal Information can be disclosed
for this purpose and may be made public.

HOW DO WE COLLECT AND USE INFORMATION THROUGH AUTOMATIC MEANS?

Eisai and third parties with whom Eisai has contracted to provide services to Eisai may also collect information
from you through browser navigational tools; cookies; pixel tags and other similar technologies. This may include: i.
Browser Navigational Tools. We and our service providers may collect and use certain technology data, such as
your computer type (Windows or Macintosh), screen resolution, Operating System (“OS”) version, Internet browser,
and Internet browser version. This type of information is collected by many browsers and can be used to help
optimize your experience on our website. ii. Cookies. We and our service providers may use “cookies” on our
websites. A cookie is a bit of information that a website sends to your web browser that helps the site remember
information about you and your preferences. There are two principal types of cookies: i. “Session” cookies are
temporary bits of information that are used to improve website navigation, block website visitors from providing
information where inappropriate and to collect aggregate statistical information on a website. These cookies are
erased once you exit your web browser or otherwise turn off your computer. ii. “Persistent” cookies are more
permanent bits of information that are placed on the hard drive of your computer and stay there unless you delete
the cookie. Persistent cookies store information on your computer so that we can, for example, retrieve information
you have previously provided (such as passwords); better determine what areas of the website you find most
valuable; and customize the website based on your preferences on an ongoing basis. You can set your browser to
accept all cookies, to reject all cookies, or to notify you whenever a cookie is offered so that you can decide each
time whether to accept it. To learn more about cookies, please visit http://www.allaboutcookies.org/. iii. Pixel Tags.
We and our service providers may also use so-called “pixel tags,” “web beacons,” “clear GIFs” or similar
technologies (collectively, “Pixel Tags”) in connection with some website pages and HTML-formatted email
messages to, among other things: track the online activity of website users and email recipients (including activity
on other websites); determine the success of marketing campaigns; and compile aggregate statistics about
website usage and response rates. iv. Other Sources. Eisai also may collect information (such as indications of your
interests, your geographic location, and other demographic information) that you or others provide, and we also
may aggregate this information and/or other information in our possession in a manner such that the end-product
does not personally identify you or any other individual and so is not Personal Information. For example, we might
aggregate information to calculate the percentage of our users who have a particular telephone area code, or to
better understand certain medical usage patterns. Such aggregate information is not considered Personal
Information for purposes of this Privacy Policy. As noted above, we and our service providers may use tracking
technologies, such as cookies and Pixel Tags, to improve the usefulness and value to you of our website, as well as
to gauge the success of marketing initiatives and to improve our marketing campaigns, by tracking your online
visits to our websites and other websites not operated by us. For example, we may use such technologies to
remind you of Eisai products when you are browsing another website or may collect aggregate information about
other websites you have browsed. We reserve the right to use information that is not Personal Information for any
other purpose as well. For example, we may use aggregated non-personal health information to publish reports on
particular topics. In some instances, we may combine non-personal information with Personal Information (such as
embedding email addresses in cookies). If we do combine any non-personal information with Personal Information,
the combined information will be treated by us as Personal Information for so long as it is so combined. IP
Addresses. Your IP Address is a number that is automatically assigned to the computer that you are using by your
Internet Service Provider (“ISP”). This number may be identified and logged automatically in our server log files
whenever users visit the website, along with the time(s) of such visit(s) and the page(s) that were visited.
Collecting IP Addresses is standard practice on the internet and is done automatically by many websites. We may
use IP addresses for purposes such as calculating website usage levels, helping diagnose server problems, ensuring
appropriate access rights by authorized users, facilitating website security, and administering the website.

WHERE DO WE STORE YOUR PERSONAL INFORMATION?

Your Personal Information is stored in secured locations and/or on servers, including in locations and servers
located in Mississauga, Ontario, Woodcliff Lake and Totowa, New Jersey, as well as Research Triangle Park, North
Carolina, or at the locations of our service providers or U.S. affiliates.

Eisai retains your Personal Information only for as long as is necessary in order to fulfill the purposes identified
within this Privacy Policy, for as long as may be required to comply with applicable laws, or as required under
Eisai’s record retention policies.

HOW DO WE PROTECT YOUR PERSONAL INFORMATION?

To help protect the confidentiality and security of your Personal Information, Eisai employs physical, administrative
and technological safeguards appropriate to the sensitivity of your Personal Information. If your Personal
Information is sent to a third party for processing, we seek to make sure, through our contracts with such third
parties, that all of your Personal Information is to be kept secure. Personal Information may only be accessed by
persons within our organization, or our third-party service providers, who require such access to carry out the
purposes identified to you or permitted or required by law. We also operate secure data networks protected by
industry standard firewall and password protection systems. We try to keep your Personal Information as accurate,
complete and up-to-date as is necessary to fulfill the purposes identified in this Privacy Policy. However, we do not
routinely update your Personal Information. If any Personal Information you have provided to us has changed,
please contact us for the purposes of updating it.

HOW CAN YOU OBTAIN ACCESS TO YOUR PERSONAL INFORMATION?

Upon your written request, and subject to certain exceptions, Eisai will give you access to the Personal Information
we hold about you. Access requests should be sent to Eisai's Privacy Officer using the contact information outlined
below.

If access to your Personal Information is denied, Eisai will notify you in writing, give reasons for the denial, and
inform you of the recourses open to you. If access is granted, Eisai will give you a reasonable opportunity to review
your Personal Information. Your Personal Information will be provided to you in an understandable form within a
reasonable time, generally within 30 days. Eisai may extend such 30-day period by up to an additional 30 days in
certain circumstances, including in cases where meeting the time limit would unreasonably interfere with the
activities of Eisai or the time required to undertake any consultations necessary to respond to your request would
make the time limit impracticable to meet. You will be able to challenge the accuracy and completeness of your
Personal Information and have it amended as appropriate.

CHILDREN AND PARENTS

Eisai does not typically collect Personal Information from children. If a child has already provided us with Personal
Information, his or her parent or guardian may contact us for the purpose of deleting this information.

THIRD PARTY WEBSITES

Our websites may contain links to other third-party websites. These other websites may have their own privacy
policies and terms and conditions that are not governed by this Privacy Policy. We are not responsible for the
privacy practices or the content of any website(s) owned and operated by any such third parties. Other websites
may collect and treat information collected differently, so we encourage you to carefully read and review the
privacy policy for each website you visit. Any links from our websites to other websites, or references to products,
services or publications other than those of Eisai, do not imply the endorsement or approval of such websites,
products, services or publications by Eisai.

HOW CAN YOU OBTAIN FURTHER INFORMATION REGARDING THIS POLICY?

Eisai has appointed a Privacy Officer to oversee compliance with this Privacy Policy and applicable privacy laws.
For more information on Eisai's privacy practices, please contact our Privacy Officer at (905) 361-7130 or by writing to Privacy_Officer_Canada@eisai.com.

CHANGES TO OUR PRIVACY POLICY

Eisai reserves the right to modify or supplement this Privacy Policy at any time. If we make a change to this Privacy
Policy, we will make such revised policy and changes available on our website. However, Eisai will obtain the
necessary consents required under applicable privacy laws if it seeks to collect, use or disclose your Personal
Information for purposes other than those for which your consent has been previously obtained, unless otherwise
required or permitted by law. Your continued access to and/or use of our website after any such changes
constitutes your acceptance of, and agreement to be legally bound by, this Privacy Policy, as revised. Please
periodically review this Privacy Policy so that you know what personal information we collect, how we use it, and
with whom we may share it.
