1.7 We may make available to You, for Your installation, copying and/or use in
connection with the Services, from time to time, a variety of software, data and
other content and printed and electronic documentation (the "Twilio

associated with Your account and data therein.

convenience, by closing Your account for any Service for which we provide an
account closing mechanism.

Services to You), for any reason or for no reason, at our discretion at any time
by providing You thirty (30) days' advance notice in accordance with the notice
provisions set forth in Section 10 below. If Twilio determines that providing

Services to You), with no notice.

the Services for which there is reason to believe such traffic or use is
fraudulent or negatively impacting the operating capability of the Service;
(iii) we determine, in our sole discretion, that our provision of any of the
Services to You is prohibited by applicable law, or has become impractical or
unfeasible for any legal or regulatory reason; or (iv) subject to applicable
law, upon Your liquidation, commencement of dissolution proceedings, disposal of
Your assets, failure to continue Your business, assignment for the benefit of
creditors, or if You become the subject of a voluntary or involuntary bankruptcy

2.7 Following the suspension or termination of Your right to use the Services by
us or by You for any reason other than a termination for cause, You shall be
entitled to take advantage of any post-termination assistance we may generally
elect to make available with respect to the Services such as data retrieval
arrangements. We may also endeavor to provide You with unique post- suspension
or post-termination assistance, but we shall be under no obligation to do so.
Your right to take advantage of any such assistance, whether generally made
available with respect to the Services or made available uniquely to You, shall
be conditioned upon Your acceptance of and compliance with any fees and terms we
specify for such assistance.

3. DOWNTIME AND SERVICE SUSPENSIONS; SECURITY

3.1 In addition to our rights to terminate or suspend Services to You as
described in Section 2 above, You acknowledge that: (i) Your access to and use
of the Services may be suspended for the duration of any unanticipated or
unscheduled downtime or unavailability of any portion or all of the Services for
any reason, including as a result of power outages, system failures or other
interruptions; and (ii) we shall also be entitled, without any liability to You,
to suspend access to any portion or all of the Services at any time, on a
Service-wide basis: (a) for scheduled downtime to permit us to conduct
maintenance or make modifications to any Service; (b) in the event of a denial
of service attack or other attack on the Service or other event that we
determine, in our sole discretion, may create a risk to the applicable Service,
to You or to any of our other customers if the Service were not suspended; or
(c) in the event that we determine that any Service is prohibited by applicable
law or we otherwise determine that it is necessary or prudent to do so for legal
or regulatory reasons (collectively, "Service Suspensions"). Without limitation
to Section 7, we shall have no liability whatsoever for any damage, liabilities,
losses (including any loss of data or profits) or any other consequences that
You may incur as a result of any Service Suspension. To the extent we are able,
we will endeavor to provide You notice of any Service Suspension in accordance
with the notice provisions set forth in Section 10 below and to post updates
regarding resumption of Services following any such suspension, but shall have
no liability for the manner in which we may do so or if we fail to do so.

3.2 We strive to keep information You provide to us secure, but cannot guarantee
that we will be successful at doing so. Accordingly, without limitation to
Section 7 below, You acknowledge that You bear sole responsibility for adequate
security, protection and backup of Your content including all audio recordings
associated with Your account. We strongly encourage You, where available and
appropriate, to use encryption technology to protect Your content from
unauthorized access and to routinely archive Your content. We will have no
liability to You for any unauthorized access or use, corruption, deletion,
destruction or loss of any of Your content.

4. PROMOTIONAL CREDITS

4.1 We may award credits, points or any of our other virtual currencies (each
individually or collectively referred to as "Promotional Credits") in connection
with promotions or other giveaways. Acquisition of Promotional Credits provides
only a limited, non-transferable, non- sublicensable, revocable license to use
such Promotional Credits to access Services that we expressly make available for
use with the Promotional Credits. Promotional Credits have no monetary value and
do not constitute currency or property of any type. Promotional Credits may not
be sold or transferred, and cannot be exchanged for cash or for any other goods
or services, except for Services. We may cancel any Promotional Credits
transferred, assigned or sold in violation of this Agreement.

                                       5
<PAGE>
4.2 During the term of Your license to Promotional Credits, You have the right
to redeem Promotional Credits for selected Services. We neither guarantee the
availability of particular Services nor that particular Services will be offered
for any particular time.

4.3 The term of Your Promotional Credits license starts when You acquire such
Promotional Credits and, subject to this Agreement, expires upon the earlier of
(a) twelve months from the date of award (as the context requires and applicable
to each individual award); or (b) the date that Your access to the Services is
expired, suspended, cancelled or terminated as set forth herein. If You do not
use Your account for twelve months, or if You delete Your account, any remaining
Promotional Credits may be redeemed, cancelled or expired by us. Once
Promotional Credits are redeemed for Services, such Services are not returnable,
exchangeable or refundable for Promotional Credits or any other virtual
currency, or for cash or goods or services.

4.4 Promotional Credits may only be held by legal residents of countries where
access to and use of the Services and Promotional Credits are permitted.
Promotional Credits may only be awarded by us or through means we provide on the
Website or otherwise expressly authorize. We can cancel or suspend Your access
to Promotional Credits in our sole discretion and without prior notice, if (a)
You fail to comply with this Agreement; or (b) if we otherwise suspect fraud or
misuse of Promotional Credits. We have no obligation or responsibility to, and
will not reimburse You for, any Promotional Credits lost due to such
cancellation or suspension.

4.5 We have the absolute right to offer, manage, regulate, modify and/or
eliminate Promotional Credits or any portion thereof, at any time, without any
liability to You.

5. FEES

5.1 In its sole discretion, Twilio shall determine whether You are eligible for
a free trial subscription to its Services, which terms of the free trial are set
forth here. Free trials are limited to one per person, and if we find that You
have created multiple free trial accounts, we reserve the right to suspend those
accounts and take actions to prevent additional violations.

5.2 To the extent the Services or any portion thereof are made available for any
fee, You agree to pay all applicable fees (including any minimum subscription
fees) as set forth here. You agree to pay any carrier costs, such as fees for
porting Your existing telephone numbers into or out of the Services. We may
increase or add new fees for any existing Service or Service feature by giving
You 30 days' advance notice. All fees payable by You are exclusive of applicable
taxes and duties, including, without limitation, VAT and applicable sales tax.
You will provide such information to us as reasonably required to determine
whether we are obligated to collect VAT from You. You are responsible for any
charges imposed on Twilio by a carrier related to government fees for
telecommunications, including but not limited to, Universal Service Fund fees,
if applicable.

5.3 We may specify the manner in which You will pay any fees, and any such
payment shall be subject to our general accounts receivable policies from time
to time in effect. All amounts payable by You under this Agreement will be made
without setoff or counterclaim and without deduction or withholding. If any
deduction or withholding is required by applicable law, You shall notify us and
shall pay such additional amounts to us as necessary to ensure that the net
amount that we receive, after such deduction and withholding, equals the amount
we would have received if no such deduction or withholding had been required.
Additionally, You shall provide us with documentation that the withholding and
deducted amounts have been paid to the relevant taxing authority.

contact us at help@twilio.com within 90 days of the date of the activity that
generated such dispute, and we will attempt to resolve the matter. Any and all

account, but in no event shall there be any cash refunds. Disputes older than 90
days shall not be entitled to any refunds or credits.

7. REPRESENTATIONS AND WARRANTIES; DISCLAIMERS; LIMITATIONS OF LIABILITY

7.1 You represent and warrant that You will not use the Website (including our
forums and comments sections), Services, Twilio Properties, Twilio Marks, Your
Application or Your Content in a manner that violates the Acceptable Use Policy.
To this effect, we ask that You take reasonable precautions to promote best
practices. Although Twilio does not assume the duty or obligation to monitor any
materials created, posted or uploaded by You or any third parties, Twilio
reserves the right, in its sole and absolute discretion, to monitor any and all
materials posted or uploaded by You or any third parties at any time without
prior notice to ensure that they conform to any usage guidelines or policies
(including our Acceptable Use Policy) relating to our Website or Services.

7.2 You also acknowledge and understand that we do NOT currently allow You to
access any 911 or similar emergency services (no traditional 911, E911, or
similar access to emergency services). The Services are not intended to replace
any primary phone service, such as a traditional landline or mobile phone, that
may be used to contact emergency services.

7.3 You represent and warrant: (i) that You are solely responsible for the
development, operation, and maintenance of Your Application and for Your
Content, including without limitation, the accuracy, appropriateness and
completeness of Your Content and all product- related materials and
descriptions; (ii) that You have the necessary rights and licenses, consents,
permissions, waivers and releases to use and display Your Application and Your
Content; (iii) that neither Your Application nor Your Content (a) violates,
misappropriates or infringes any rights of us or any third party, (b)
constitutes defamation, invasion of privacy or publicity, or otherwise violates
any rights of any third party, or (c) is designed for use in any illegal

                                       8
<PAGE>
activity or promotes illegal activities, including, without limitation, in a
manner that might be libelous or defamatory or otherwise malicious, illegal or
harmful to any person or entity, or discriminatory based on race, sex, religion,
nationality, disability, sexual orientation, or age; (iv) that neither Your
Application nor Your Content contains any harmful components; and (v) to the
extent to which You use any of the Twilio Marks, that You will conduct Your
business in a professional manner and in a way that reflects favorably on the
goodwill and reputation of Twilio. You also represent and warrant that You are
responsible for any charges incurred by virtue of Your use of the Application,
no matter whether the Application acted in error.

7.4 You further understand and agree that You will have use of the telephone
number(s) that are provided as part of the services only until the end of the
term of Your Agreement with Twilio or until Twilio no longer provides You with
Service. You understand and agree that Twilio is the customer of record for all
telephone number(s) provided as part of the Services and, therefore, Twilio has
certain rights with respect to porting of the number(s) ("Porting" is causing or
attempting to cause number(s) to be transferred, switched, or otherwise moved to
any other service provider, telephone carrier, or any other person or entity).
As the customer of record for the telephone number(s), Twilio owns the telephone
number(s) assigned to you. Twilio generally ports a telephone number at the
request of a customer. Twilio reserves the right to refuse to port any telephone
number(s) in its sole discretion.

**7.4.1 If You "ported in" any telephone number(s) in connection with Your use
of Services, Twilio assigned You one or more toll free telephone numbers, You
are entitled to "port out" a telephone number under non-U.S. law, or Twilio has
agreed to port out any telephone number(s), You may "port out" such number(s)
only if You satisfy the following requirements: (1) You provide written notice
to Twilio of Your intent to "port out" such number(s) no later than thirty (30)
days after providing Twilio notice of Your intent to terminate this Agreement
(the "Porting Notice Period"); (2) Your new telephone carrier provides Twilio's
telephone carrier a duly executed porting request prior to the expiration of the
Porting Notice Period; (3) You have paid Twilio for all Services provided to You
prior to the date You provide Twilio notice of Your intent to terminate this
Agreement; and (4) You have paid Twilio any administrative fees associated with
processing the port. You hereby authorize Twilio to charge Your account in the
applicable amount for the administrative fees in subsection (4) above or to
otherwise arrange to make this payment to Twilio within the Porting Notice
Period. The porting process can be lengthy; if You would like to maintain Your
account with the company during the porting process, You must maintain Your
account in an active status and not terminate Your account until the porting out
is complete. Regardless of when the port out is complete, You will continue to
be responsible to pay all applicable account fees with respect to the telephone
numbers until You formally terminate this Agreement. If You fail to satisfy any

respect to any such change, whether based on contractual, tort or other grounds,

each of our and their business partners (including third party sellers on
websites operated by or on behalf of us) and each of our and their respective
employees, officers, directors and representatives, harmless from and against
any and all claims, losses, damages, liabilities, judgments, penalties, fines,
costs and expenses (including reasonable attorneys fees), arising out of or in
connection with any claim arising out of (i) Your use of the Services, Twilio

and/or in violation of the applicable restrictions, the Acceptable Use Policy,
and/or applicable law, (ii) Your Application, Your Content, or the combination

<PAGE>
8.2 We agree to promptly notify You of any claim subject to indemnification;
provided that our failure to promptly notify You shall not affect Your
obligations hereunder except to the extent that our failure to promptly notify
You delays or prejudices Your ability to defend the claim. At our option, You
will have the right to defend against any such claim with counsel of Your own
choosing (subject to our written consent) and to settle such claim as You deem
appropriate, provided that You shall not enter into any settlement without our
prior written consent and provided that we may, at any time, elect to take over
control of the defense and settlement of the claim.

9. DISPUTES

9.1 Notwithstanding anything to the contrary, we may seek injunctive or other
relief in any state, federal, or national court of competent jurisdiction for
any actual or alleged infringement of Twilio's or any third party's intellectual
property rights and/or proprietary rights. You further acknowledge that our
rights in the Twilio Services, Twilio Properties and the Twilio Marks are of a
special, unique, extraordinary character, giving them peculiar value, the loss
of which cannot be readily estimated and may not be adequately compensated for
in monetary damages.

9.2 By using the Services, You agree that the laws of the State of California,
without regard to principles of conflicts of laws, will govern this Agreement
and any dispute of any sort that might arise between You and us.

9.3 Arbitration. YOU AND TWILIO BOTH AGREE TO RESOLVE DISPUTES ONLY BY
ARBITRATION. THERE'S NO JUDGE OR JURY IN ARBITRATION, AND THE PROCEDURES MAY BE
DIFFERENT, BUT AN ARBITRATOR CAN AWARD YOU THE SAME DAMAGES AND RELIEF, AND MUST
HONOR THE SAME TERMS IN THIS AGREEMENT, AS A COURT WOULD. IF THE LAW ALLOWS FOR
AN AWARD OF ATTORNEYS' FEES, AN ARBITRATOR CAN AWARD THEM TOO. YOU AND TWILIO
ALSO BOTH AGREE THAT:

**9.3.1** THE FEDERAL ARBITRATION ACT APPLIES TO THIS AGREEMENT. ANY DISPUTE
THAT IN ANY WAY RELATES TO OR ARISES OUT OF THIS AGREEMENT OR FROM ANY SERVICES
YOU RECEIVE FROM US WILL BE RESOLVED BY ONE OR MORE NEUTRAL ARBITRATORS BEFORE
THE AMERICAN ARBITRATION ASSOCIATION ("AAA"). YOU CAN ALSO BRING ANY ISSUES YOU
MAY HAVE TO THE ATTENTION OF FEDERAL, STATE, OR LOCAL GOVERNMENT AGENCIES, AND
IF THE LAW ALLOWS, THEY CAN SEEK RELIEF AGAINST US FOR YOU.

**9.3.2** UNLESS YOU AND TWILIO AGREE OTHERWISE, THE ARBITRATION WILL TAKE PLACE
IN SAN FRANCISCO, CALIFORNIA. YOU CAN GET PROCEDURES, RULES AND FEE INFORMATION
FROM THE AAA (WWW.ADR.ORG) OR FROM US.

**9.3.3** THIS AGREEMENT DOESN'T ALLOW CLASS OR COLLECTIVE ARBITRATIONS EVEN IF
THE AAA PROCEDURES OR RULES WOULD. NOTWITHSTANDING ANY OTHER PROVISION OF THIS
AGREEMENT, THE ARBITRATOR MAY AWARD MONEY OR INJUNCTIVE RELIEF ONLY IN FAVOR OF
THE INDIVIDUAL PARTY SEEKING RELIEF AND ONLY TO THE EXTENT NECESSARY TO PROVIDE
RELIEF WARRANTED BY THAT PARTY'S INDIVIDUAL CLAIM. NO CLASS OR REPRESENTATIVE OR
PRIVATE ATTORNEY GENERAL THEORIES OF LIABILITY OR PRAYERS FOR RELIEF MAY BE
MAINTAINED IN ANY ARBITRATION HELD UNDER THIS AGREEMENT.

9.3.4** IF EITHER YOU OR TWILIO INTENDS TO SEEK ARBITRATION UNDER THIS
AGREEMENT, THE PARTY SEEKING ARBITRATION MUST FIRST NOTIFY THE OTHER PARTY OF
THE DISPUTE IN WRITING AT LEAST 30 DAYS IN ADVANCE OF INITIATING THE
ARBITRATION. NOTICE TO TWILIO SHOULD BE SENT AS REQUIRED BY THIS AGREEMENT. THE
NOTICE MUST DESCRIBE THE NATURE OF THE CLAIM AND THE RELIEF BEING SOUGHT. IF YOU
AND TWILIO ARE UNABLE TO RESOLVE OUR DISPUTE WITHIN 30 DAYS, EITHER PARTY MAY
THEN PROCEED TO FILE A CLAIM FOR ARBITRATION.

                                       13
<PAGE>
**9.3.5** AN ARBITRATION AWARD AND ANY JUDGMENT CONFIRMING IT APPLY ONLY TO THAT
SPECIFIC CASE; IT CAN'T BE USED IN ANY OTHER CASE EXCEPT TO ENFORCE THE AWARD
ITSELF.

**9.3.6** IF FOR SOME REASON THE PROHIBITION ON CLASS ARBITRATIONS SET FORTH IN
SUBSECTION (3) CANNOT BE ENFORCED, THEN THE AGREEMENT TO ARBITRATE WILL NOT
APPLY.

**9.3.7** IF FOR ANY REASON A CLAIM PROCEEDS IN COURT RATHER THAN THROUGH
ARBITRATION, YOU AND TWILIO AGREE THAT THERE WILL NOT BE A JURY TRIAL. YOU AND
TWILIO UNCONDITIONALLY WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY ACTION,
PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT IN ANY
WAY. IN THE EVENT OF LITIGATION, THIS PARAGRAPH MAY BE FILED TO SHOW A WRITTEN
CONSENT TO A TRIAL BY THE COURT. YOU AND TWILIO ALSO AGREE THAT ANY DISPUTE
HEREUNDER SHALL BE ADJUDICATED IN ANY STATE OR FEDERAL COURT IN SAN FRANCISCO,
CALIFORNIA, AND YOU CONSENT TO EXCLUSIVE JURISDICTION AND VENUE IN SUCH COURTS.
