INFORMATION ON THE WEBSITE AND IN ANY COMMUNICATIONS FROM US IS
PROVIDED FOR EDUCATIONAL AND INFORMATIONAL PURPOSES ONLY AND
DOES NOT CONSTITUTE MEDICAL, LEGAL, OR REGULATORY ADVICE.
STATEMENTS REGARDING PRODUCTS HAVE NOT BEEN EVALUATED BY THE FDA

YOU ARE SOLELY RESPONSIBLE FOR: (I) DETERMINING WHETHER A PRODUCT IS

regulations; (ii) the Controlled Substances Act and Drug Enforcement Administration
regulations, where applicable; (iii) the Toxic Substances Control Act for chemical substances;

safety procedures; and (iii) properly classify, store, handle, and dispose of Products and related
waste, including via licensed hazardouswaste vendors where required.


You acknowledge that labeling Products as “For Research Use Only” does not automatically
exempt them from regulatory oversight. Any misuse, misbranding, or promotional claims
inconsistent with true researchonly intent may cause Products or your activities to become
subject to additional regulations, for which you, not Katharos, are responsible.


ORDERS, PRICING, PAYMENT & AUTHORIZATION


All orders are subject to our acceptance. Product listings, descriptions, and prices on the Website
and other documents are invitations to order, not binding offers. A binding contract is formed
only when we send you an order confirmation or ship the Products.


All prices displayed on this Website are inclusive of applicable taxes unless otherwise stated. By
placing an order, you agree that the total amount charged at checkout includes any required sales,
use, or similar taxes imposed by applicable laws and regulations. We calculate and collect taxes
based on the shipping address provided and in accordance with state and local tax requirements.
In certain jurisdictions where tax collection obligations may vary or are not clearly defined, we
reserve the right to include an estimated tax amount within the listed price. You are solely
responsible for any additional taxes, duties, or governmental fees that may apply to your order
under applicable law. We reserve the right to adjust pricing to reflect changes in tax rates or
applicable laws without prior notice.


We may accept credit and debit cards, ACH/echeck, wire transfers, and other payment methods
as listed at checkout. You authorize us (and our payment processors) to charge your designated
payment method for the full order amount, including taxes and shipping.
By providing a card, you represent and warrant that: (i) you are the authorized cardholder or
have permission from the cardholder; (ii) the card details are accurate and current; and (iii) you
will not dispute, “call back,” or request a chargeback so long as the transaction corresponds to
these Terms and your order as submitted.


By providing bank account information, you authorize us to initiate onetime or recurring debits
(as applicable) in the amount of your order or agreed charges, and you represent that: (i) you are
an authorized signer on the account; and (ii) you will not issue a stop payment, reversal, or
dispute so long as the transaction corresponds to these Terms and your order as submitted.

Once you submit an order and payment is authorized, you may not modify payment details for
that order. If you believe you made an error, you must contact us immediately. We reserve the
right to decline any requested changes.
If any amount you owe is not received when due, we may: (i) assess interest at the maximum rate
allowed by law or, if less, 1.5% per month, until paid in full; (ii) suspend or cancel pending
shipments; and (iii) recover from you all reasonable costs of collection, including attorneys’ fees
and court costs.


CHARGEBACKS, PAYMENT DISPUTES & LIQUIDATED DAMAGES
IF YOU BELIEVE A CHARGE IS UNAUTHORIZED, INCORRECT, OR RELATED TO AN
ISSUE WITH YOUR ORDER, YOU AGREE TO CONTACT US PROMPTLY AND GIVE US
A REASONABLE OPPORTUNITY TO INVESTIGATE AND RESOLVE THE
MATTER BEFORE INITIATING ANY CHARGEBACK OR BANK DISPUTE, TO THE
EXTENT ALLOWED BY YOUR CARDHOLDER/ACH RIGHTS.


A “Chargeback” means any chargeback, reversal, or dispute that: (i) is based on circumstances
allocated to you under these Terms; (ii) misrepresents the facts (for example, stating that you did
not place the order when you in fact did); or (iii) is otherwise initiated in bad faith or in clear
violation of these Terms. If a Chargeback is initiated or sustained, you will be in material breach
of this Agreement.


To the fullest extent permitted by law, if you initiate or cause a Chargeback, you agree that we
shall be entitled to recover from you: (i) the full amount of the disputed transaction(s); (ii)
reasonable liquidated damages relating to the administrative burden, investigation costs,
processor penalties, and harm to our merchant accounts; (iii) all chargeback fees and related bank
or processor fees; (iv) our reasonable attorneys’ fees and costs incurred in contesting the
chargeback or collecting the above amounts; and (v) interest on all of the above at the maximum
rate permitted by applicable law from the date the chargeback was posted until paid in full. These
liquidated damages are intended to be compensatory, not a penalty. If a court or arbitrator
determines that any portion is unenforceable, it shall be reduced to the maximum amount
permitted by law; the remainder shall remain in effect.


You acknowledge that: (i) chargebacks and fraudulent disputes cause significant damages
beyond the face value of the order; (ii) the administrative and reputational costs are difficult to
quantify precisely in each case; and (iii) the liquidated damages framework above is a reasonable
estimate of those losses at the time of contracting.

ARBITRATION AGREEMENT; WAIVER OF TRIAL BY JURY AND WAIVER OF
CLASS ACTION.
THESE TERMS CONTAIN A BINDING ARBITRATION PROVISION.

YOU AGREE THAT
ALL DISPUTES BETWEEN YOU AND KATHAROS WILL BE RESOLVED BY
MANDATORY BINDING ARBITRATION AND YOU WAIVE ANY RIGHT TO

PARTICIPATE IN A CLASS ACTION LAWSUIT OR CLASS-WIDE ARBITRATION.
PLEASE READ THE FOLLOWING PARAGRAPHS CAREFULLY BECAUSE THEY
REQUIRE YOU TO ARBITRATE DISPUTES WITH KATHAROS AND LIMIT THE
MANNER IN WHICH YOU CAN SEEK RELIEF. 


Any dispute, claim or controversy of any nature arising out of or relating in any way to the
Products, use of the Website, the Services, these Terms, or this Arbitration Agreement (as
defined below), including without limitation the interpretation, validity, scope, or applicability of
these Terms or the Arbitration Agreement (hereinafter, collectively, the “Dispute”), which cannot
be resolved informally, shall be resolved by binding arbitration on an individual, and not a class
or representative, basis under the terms set forth below (the “Arbitration Agreement”). This
Arbitration Agreement applies to you and Katharos, and to any of our subsidiaries, affiliates,
agents, employees, predecessors in interest, successors in interest, and assigns.

THE PARTIES
UNDERSTAND THAT THEY WOULD HAVE HAD A RIGHT OR OPPORTUNITY TO
LITIGATE DISPUTES THROUGH A COURT, TO HAVE A JUDGE OR JURY DECIDE
THEIR CASE, AND TO PARTICIPATE IN A CLASS ACTION OR OTHER PROCEEDING
INVOLVING MULTIPLE CLAIMANTS, BUT THEY INSTEAD CHOOSE AND AGREE TO
HAVE ALL DISPUTES AS SET FORTH HEREIN DECIDED THROUGH INDIVIDUAL
ARBITRATION. 


Disputes where the amount in controversy is less than US$6,000 and filed by you or Katharos
individually in a small claims court are not subject to arbitration, so long as the disputes remain
in such court and advance only an individual (non-class, non-representative) claim for relief. In
the event of any actual, alleged or threatened violation of confidentiality or violation of
Katharos’ or its licensor’s intellectual property or other proprietary rights, Katharos may
immediately resort to court proceedings in a court of competent jurisdiction as set forth below in
order to seek immediate injunctive relief without posting of a bond, proof of damages or other
similar requirement. The institution of any action for injunctive relief shall not constitute a
waiver of the right or obligation of any party to submit any claim seeking relief other than
injunctive relief to arbitration. 


You expressly agree that any and all actions taken under the Arbitration Agreement and related
provisions, including but not limited to all filings, orders, judgments, and awards made in any
arbitration proceeding, are confidential and may not be disclosed to any third party, except as
otherwise may be required by law. 


The arbitration proceeding will be administered by the American Arbitration Association
(“AAA”) under the AAA’s Commercial Arbitration Rules (the “AAA Rules”) before a single
arbitrator selected pursuant to the AAA rules. The decision of the arbitrator will be final and
binding. Any final award or judgment may be filed and enforced in any court of competent
jurisdiction.


Notwithstanding the foregoing, if the AAA determines that its Consumer Arbitration Rules are
applicable to a particular Dispute, those rules shall apply to the extent required by the AAA,
including with respect to the allocation of arbitration fees and costs. Any arbitration proceeding

may not be consolidated or joined with any other proceeding and will not proceed as a class
action. 


The place of arbitration shall be in Sheridan County, Wyoming, unless otherwise agreed to in
writing by all parties to the arbitration. The parties acknowledge that this Arbitration Agreement
evidences a transaction involving interstate commerce, and the Federal Arbitration Act, 9 U.S.C.
§ 1, et seq., as may be amended from time to time, shall govern the interpretation, enforcement
and proceedings pursuant to this Arbitration Agreement. To the extent state law is applicable, the
laws of the State of Wyoming shall apply without regard to conflict of laws provisions. 
This Arbitration Agreement provision will survive the termination of these Terms. Except as set
forth in the Section titled Class Action Waiver below, if any portion of this Arbitration
Agreement is deemed invalid or unenforceable through a final judicial determination, the entire
Arbitration Agreement shall be null and void. No portion of this Arbitration Agreement may be
amended, severed, or waived absent a written agreement between you and Katharos. 
The parties agree that they must initiate arbitration within one (1) year after any Dispute arose;
otherwise, the Dispute is permanently barred. 


YOU AND KATHAROS AGREE THAT EACH MAY BRING CLAIMS AGAINST THE
OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF
OR CLASS MEMBER IN ANY PURPORTED CLASS OR REPRESENTATIVE
PROCEEDING.

Further, unless both you and Katharos agree otherwise, the arbitrator may not
consolidate one or more person’s claims with your claims and may not otherwise preside over
any form of a representative or class proceeding. If there is a final judicial determination that
applicable law precludes enforcement of this section’s limitations as to a particular claim for
relief, then that claim (and only that claim) must be severed from the arbitration and may be
brought in court.


TO THE EXTENT ANY CLAIM IS DETERMINED NOT TO BE SUBJECT TO
ARBITRATION, OR FOR ENFORCEMENT OF AN ARBITRATION AWARD, YOU
CONSENT TO THE EXCLUSIVE JURISDICTION AND VENUE OF THE STATE AND
FEDERAL COURTS LOCATED IN SHERIDAN COUNTY, WYOMING. TO THE EXTENT
ANY DISPUTE PROCEEDS IN COURT RATHER THAN ARBITRATION, YOU AND
KATHAROS IRREVOCABLY WAIVE ANY RIGHT TO A JURY TRIAL.
LYOPHILIZED PRODUCTS


Some of our products are lyophilized, meaning they have been freeze-dried for optimal
preservation, stability, and ease of shipping. This process results in Products that are not in liquid
form. The lyophilization process is part of our commitment to delivering high-quality, stable, and
reliable products to our customers. By purchasing our Products, you acknowledge you are aware
of the lyophilized nature of our Products. You accept that the Products are not in a liquid form
and understand the reason for the lyophilization process. Given the specific nature of our
lyophilized Products, we do not accept returns or provide refunds if a customer complains about
the Product not being in liquid form. This policy applies to all our Products without exception.

You have the right to return or request a refund for Products under other circumstances that are
consistent with our Refund Policy, but not based on the product being freeze-dried or not in
liquid form.


COMMUNICATIONS BY TEXT MESSAGE AND EMAIL 


By accepting these Terms and/or by sending us an initial text message (an “SMS Enrollment”),
you consent to receiving text messages sent via an automatic telephone dialing system regarding
your account and use of the Websites, Products and Services. These text messages may include
order confirmations, shipping notifications and other transactional messages. 


With your SMS Enrollment, you represent and understand that: (i) you are the owner or
authorized user of the mobile device you used in order to initiate the SMS Enrollment; (ii) you
are authorized to approve any applicable charges in connection with the text messages you send
to and receive from us; (iii) you will be responsible for all messaging and other data charges that
may apply for any text messages sent by you to us, or from us to you; and (iv) neither us, nor
your or our mobile carriers, will be liable for delayed or undelivered messages. 


Note that access to the Website, Products and Services is not conditioned upon your consent to
receive text messages from us, and you can opt-out of any of our SMS services at any time by
texting “STOP” to the message received, from the mobile device that is subscribed to receive the
SMS messages.

After you send the text message “STOP” to us, we may send you one final text
message to confirm that you have been unsubscribed. If you have opted-in to receive more than
one type of text message from us, you will need to opt-out of each SMS service to which you are
subscribed. Until you have done so, you may continue to receive the types of text messages from
us that you have opted-in to receive but have not unsubscribed from. 


You also understand that while we take your privacy and the security of your information very
seriously, the transmission of information over the internet and mobile networks is not 100%
secure. Text messages and emails that you send to or receive from us are not encrypted, which
means that it is possible they may be intercepted by third parties. If you choose to send or receive
