10. Arbitration Agreement and Class Action Waiver

Arbitration Agreement and Class Action Waiver

THIS SECTION CONSTITUTES AN ARBITRATION AGREEMENT (“Arbitration Agreement”). IT REQUIRES YOU AND BIOHUB TO AGREE TO RESOLVE ALL DISPUTES BETWEEN US THROUGH BINDING INDIVIDUAL ARBITRATION, SO PLEASE READ IT CAREFULLY.

10.1 Applicability

In the unlikely event we end up in a legal dispute, you and Biohub agree that all Disputes, including Enforceability Disputes, will be resolved exclusively in binding arbitration on an individual basis, except that you and Biohub are not required to arbitrate IP Disputes.

Notwithstanding the foregoing, either you or Biohub may bring an individual action in small claims court.

(1) A “Dispute” means a dispute, claim or controversy arising out of or relating to the Services or these Terms; whether that dispute is (1) based on past, present or future events; or (2) in tort, contract, warranty, statute, regulation, or other legal or equitable basis.

(2) An “Enforceability Dispute” means a Dispute relating to the interpretation, applicability, or enforceability of this Arbitration Agreement, including the formation of the contract, the arbitrability of any Dispute, and any claim that all or any part of this agreement is void or voidable.(3) An “IP Dispute” means a Dispute relating to the ownership or enforcement of intellectual property rights.

10.2 Waivers

(1) Waiver of Jury Right. YOU AND BIOHUB ARE EXPRESSLY GIVING UP ALL RIGHTS TO A JURY TRIAL OR COURT TRIAL BEFORE A JUDGE, EXCEPT AS EXPRESSLY PROVIDED IN THIS ARBITRATION AGREEMENT. The arbitrator’s decision will be final and binding on both you and us, subject to review solely on the grounds set forth in the Federal Arbitration Act (“FAA”).

(2) Waiver of Class or Consolidated Actions. YOU AND BIOHUB AGREE THAT ALL DISPUTES MUST BE ARBITRATED OR LITIGATED ON AN INDIVIDUAL BASIS AND NOT ON A CLASS, COLLECTIVE ACTION, OR REPRESENTATIVE BASIS. The validity of this waiver – and whether an action may proceed as a class, collective, or representative action – must be decided by a court.

10.3 Initiating a Dispute

To initiate a Dispute, a party must send to the other party written notice of that Dispute containing: (a) the name, address, and contact information of the party giving notice; (b) the facts giving rise to the Dispute; and (c) the relief requested. Notices sent to Biohub must be sent by mail to the address provided in Section 14 below.

You and we agree that the parties shall (in good faith) meet and attempt to resolve the Dispute within 30 days. If the Dispute is not resolved during that time period, then you and a representative of Biohub shall (in good faith) meet and attempt to resolve the Dispute through non-binding mediation with a mutually agreed-upon mediator within 30 additional days. If you and we do not reach an agreement to resolve the dispute within that 60-day period, you or we may commence an arbitration proceeding or file a claim in small claims court.

10.4 Arbitration Rules and Procedure

(1) Rules. The Federal Arbitration Act governs the interpretation and enforcement of this Arbitration Agreement. Judicial Arbitration & Mediation Services, Inc. (“JAMS”) will administer the arbitration before a single arbitrator, and the arbitration will be initiated and conducted according to the Streamlined Arbitration Rules and Procedures (the “JAMS Rules”), to the extent they are not inconsistent with the terms of this Arbitration Agreement. The JAMS Rules and instructions about how to initiate an arbitration are available at https://www.jamsadr.com/rules-streamlined-arbitration (as of the date of this agreement) or 1-800-352-5267.

(2) Fees. Pursuant to the JAMS Consumer Arbitration Minimum Standards, Biohub will bear all costs of the arbitration (including any JAMS Case Management Fee and all professional fees for the arbitrator’s services), except for the filing fee if you are the party initiating the arbitration.

(3) Manner and Location of Arbitration. You may choose to have the arbitration conducted by telephone, in writing, online, or in person. If in person, you may choose to have the arbitration conducted (a) in San Mateo County, California, (b) if you are not domiciled in the United States, in your country of domicile, or (c) at another location that you and we agree upon.

10.5 Opt out

You may opt out of this Arbitration Agreement by notifying us no later than 30 days after first becoming subject to it. Your notice must include your name, address, and a clear statement that you want to opt out of this Arbitration Agreement. Notices sent to Biohub must be sent by mail to the address provided in Section 14 of this Agreement.

10.6 Severability

If any portion of this Arbitration Agreement is found to be unlawful, void or for any reason unenforceable, then that portion shall be severed and the remainder of this Arbitration Agreement shall be given full force and effect.

11. General Terms

11.1  Entire Agreement and 

These Terms constitute the entire agreement between the parties with respect to the subject matter hereof and your use of the Services, and supersedes all other agreements and understandings, both written and oral, between the parties with respect to the subject matter hereof. If any provision of these Terms is found unlawful or unenforceable, then that provision shall be deemed severable from these Terms and shall not affect the validity and enforceability of any remaining provisions, and any unenforceable terms will be reformed to the extent possible to reflect the intent of the parties. No waiver by either party of any breach or default hereunder shall be deemed to be a waiver of any preceding or subsequent breach or default. The section headings used herein are for reference only and shall not be read to have any legal effect.

11.2 Governing Law

These Terms and any Dispute between you and Biohub will be governed by California law and/or applicable federal law (including the Federal Arbitration Act) without regard to its choice of law or conflicts of law principles.

11.3 Jurisdiction and Venue

Subject to and without waiver of the Arbitration Agreement, you agree that any judicial proceedings (other than small claims actions) will be brought in and you hereby consent to the exclusive jurisdiction and venue in the state courts in the city and county of San Mateo, California, or federal court for the Northern District of California. For countries where this is not permissible, this won’t deprive you of any protection you have under the law of the country where you live, or access to the courts in that country.

11.4 Assignment

You may not assign or transfer your rights or obligations under these Terms (or your participation in the Services) to anyone without our prior express written consent. However, you agree that Biohub may assign these Terms in connection with a reorganization, or to a successor or assign or affiliate that agrees to assume our obligations under these Terms (and Privacy Policy) without your consent. There are no third-party beneficiaries to these Terms.

11.5 Notices

You agree the only way to provide us legal notice is at the address provided in Section 14 below.

12. Update to Terms

We may modify these Terms from time to time in which case we will update the “Last Updated” date at the top of these Terms. If we make changes that are material, we will use reasonable efforts to attempt to notify you, such as by e-mail and/or by placing a notice on the Services. However, it is your sole responsibility to review these Terms from time to time to view any such changes. The updated Terms will be effective as of the time of posting, or such later date as may be specified in the updated Terms. Your continued access or use of the Services after the modifications have become effective will be deemed your acceptance of the modified Terms. No amendment shall apply to a dispute for which an arbitration has been initiated prior to the change in Terms.

13. Termination of Access

If you breach any of the provisions of these Terms, all of your rights under these Terms will automatically terminate. Biohub may also suspend, disable, or delete your account and/or suspend, terminate or restrict your access to the Services, in its sole discretion. Biohub does not guarantee continued availability of any specific feature, dataset, conversation history, shared link, Output, or downloadable content.

In the event of account deletion, Biohub may, but is not obligated to, delete any of your User Content. Biohub assumes no responsibility for any failure to delete or for any deletion of your User Content. Provisions of these Terms that naturally survive termination will remain in effect, and termination will not limit any other rights or remedies available to Biohub under law or equity.
