This Privacy Notice (“Notice”) explains how Acceleron Pharma, Inc. (“Acceleron Pharma”, “we”, “us”, or “our”) collects, uses, discloses, and otherwise processes Personal Information about you when you access or use our website located at https://acceleron.comocreative.com/, and any other website or application owned and operated by Acceleron Pharma and its affiliates that links to this Notice (collectively, the “Site”).  This document describes how Acceleron Pharma handles and protects that information, and the rights and choices available to you with respect to such information.  For purposes of this Notice, “Personal Information” means information that identifies or relates to you or your household.

To the extent permitted by applicable law, by interacting with us and providing information to us, you agree to the collection and use of your Personal Information in accordance with this Privacy Notice.

Collection of Information:  When you engage in certain activities on the Site, such as participating in surveys, contacting customer service, providing feedback, or signing up for email updates or other promotional materials, we may ask you to provide certain information about yourself.  Such information may include your name, e-mail address, telephone number, company name, company information, as well as other information. In addition, Acceleron Pharma accumulates information from Site visitors such as what Acceleron Pharma web pages you access, how often you access them, the date, time, and duration of your use of the Site, your Internet Protocol (IP) address and/or domain name, from which website you entered the Acceleron Pharma website, and your mobile carrier and/or Internet Service Provider.  We may also gather information through the use of “cookies” as described below.

Use of Cookies and Other Technologies:  Some pages on the Acceleron Pharma Site use “cookies,” or small data files that the Site places on your hard drive, for identification purposes.  Your web browser may be programmed not to accept “cookies” or it may allow you to be notified when you are receiving a “cookie,” thus giving you the option of accepting it or rejecting it.  You are free to decline our cookies if your browser permits but doing so may interfere with your use of the Site.

We and our third-party service providers may also use technologies similar to cookies to track your interaction with the Site.  Some of these technologies may include web beacons, pixels, tags, web server logs, geo-location technologies, and Flash objects.  As with cookies, you are free to decline such technologies if your browser permits.  You should refer to your browser’s instructions to remove cached history and images from your device.  Deleting or disabling cookies will not remove Flash objects.  You should refer to Adobe’s website (http://www.adobe.com) for more information on how to disable these objects.

The Site may use Google Analytics to analyze traffic.  You can find out more information about Google Analytics cookies here:  https://developers.google.com/analytics/devguides/collection/analyticsjs/cookie-usage.  To opt-out of Google Analytics relating to your use of the Site, you can download and install the Browser Plugin available via this link: https://tools.google.com/dlpage/gaoptout?hl=en.

Acceleron Pharma and the third parties who assist in operating the Site do not respond differently or limit their practices under the terms of this Notice when you access those online services with a browser that uses a do not track signal or similar mechanism.

Use of Information:  Acceleron Pharma may use the information that it gathers for the following purposes: (i) to contact you or your company to provide information, products, or services; (ii) to provide support for, promote, and improve the Site and Acceleron Pharma offerings; (iii) to customize the Site to provide content most relevant to you; (iv) to compare information for accuracy and verify our records; or (v) to detect, investigate, and prevent activities that may violate our policies or rules or that may be otherwise illegal.  Acceleron Pharma may also use the information to communicate with you, in instances such as: (i) when we make changes to our policies; (ii) to respond to your inquiries; (iii) to contact you about your account; or (iv) to send you or your company information about promotions, offerings, and other marketing materials.

Sharing of Information:  Acceleron Pharma may share and disclose your information with Acceleron Pharma’s business partners for our marketing purposes or other entities who perform services for Acceleron Pharma.  We may share your Personal Information with service providers who are authorized to use your Personal Information only as necessary to support our business operations, such as those who provide data storage, technology support and services, customer service, risk solution provision, analytics, fraud prevention, legal services, and marketing services.  We may also share some of your Personal Information as otherwise permitted or required by law or as authorized by you.  Although Acceleron Pharma makes every effort to preserve your privacy, Acceleron Pharma may need to disclose or provide access to Personal Information if Acceleron Pharma has a good faith belief that such action is necessary to comply with the law, such as in connection with a judicial proceeding, court order or other legal process.  Acceleron Pharma will not sell Personal Information, and Acceleron Pharma does not share Personal Information with unaffiliated third parties for their use for marketing purposes.  However, in the event Acceleron Pharma goes through a business transition, such as a merger or an acquisition of its equity interests or assets, or a business reorganization, your Personal Information contained or stored by Acceleron Pharma may be part of the assets transferred.

Your Rights and Choices:  Subject to applicable law, you may have the right to (a) find out what Personal Information about you has been collected, used, and shared during the past twelve months, (b) request a copy of the Personal Information that we maintain about you, (c) request

changes to or deletions of the Personal Information, and (d) request an opt-out from the marketing materials, promotions, and other emails from us.  To exercise such rights, you may email Acceleron Pharma at DPO@xlrn.com.  If you no longer want to receive third-party email offers, please follow the third party’s unsubscribe link or opt-out instructions that should be included in every commercial message you receive.

In some cases, state laws such as the California Consumer Privacy Act of 2018 require us to verify the identity of the individual submitting a request for their Personal Information before providing a substantive response to the request.  Consistent with those requirements, and because we take the privacy and security of your Personal Information seriously, we will verify your identity by asking you to provide certain information about yourself.  Once your identity is verified, we will work to provide you with your requested information in a timely manner.  If you choose to empower an “authorized agent” to submit requests on your behalf, we will require the authorized agent to have a written authorization confirming that authority.

Some Internet browsers may be configured to send “Do Not Track” signals to the online services that you visit.  We currently do not respond to “Do Not Track” or similar signals.  To find out more about “Do Not Track,” please visit http://www.allaboutdnt.com.

Job Applicants:  When you visit the “Careers” portion of our website, we collect the information that you provide to us in connection with your job application.  This includes personal contact information, professional credentials and skills, educational and work history, social media profiles, and other information that may be included in a resume.  We use this information to facilitate our recruitment activities and process employment applications.  We may also use this information to operate and improve our websites, to communicate with you, and as otherwise provided in this Notice.

Security:  We use commercially sound efforts to maintain administrative, technical, and physical safeguards that are designed to protect the privacy and security of Personal Information.  Please note that we cannot guarantee the security of our databases or Site, nor can we guarantee that information will not be intercepted while being transmitted over the Internet.

Children Under 13:  The Site is not intended for use by children, especially those under the age of 13.  We do not knowingly collect Personal Information from children under the age of 13 (“Child”) through the Site.  If you are a parent or guardian and you learn that your Child has provided us with Personal Information, please contact us.  If we discover that a Child has provided us with Personal Information, we will take reasonable steps to delete such information from our servers.

Other Sites and Services:  We may provide links to other websites and online services operated by third parties, such as LinkedIn or Twitter.  These links are not an endorsement of, or representation that we are affiliated with, any third party.  In addition, our content may be

included on web pages or in mobile applications or online services that are not associated with us.  We do not control third party websites, mobile applications or online services, and we are not responsible for the privacy practices of these third parties.  Other websites and services follow different rules regarding the collection, use and sharing of your Personal Information.  We encourage you to read the privacy policies and terms of use of the other websites, mobile applications and online services you use.

Changes to this Privacy Notice:  Acceleron Pharma reserves the right, at our discretion, to change, modify, add, or remove portions of this Privacy Notice at any time by posting the amended Privacy Notice on the Site.  You should review this Notice periodically, and especially before you provide any Personal Information.  Your continued use of the Site after we post any modifications to the Privacy Notice will constitute your acknowledgment of the modifications and your consent to our privacy practices as described in the modifications.  If we decide to use particular information collected about you in a manner materially different from that stated at the time it was collected, we will let you know through the Site, by email, or other communication.
