# Contributor Covenant Code of Conduct
## Our Pledge
We as members, contributors, and leaders pledge to make participation in our
community a harassment-free experience for everyone, regardless of age, body
size, visible or invisible disability, ethnicity, sex characteristics, gender
identity and expression, level of experience, education, socio-economic status,
nationality, personal appearance, race, caste, color, religion, or sexual
identity and orientation.
We pledge to act and interact in ways that contribute to an open, welcoming,
diverse, inclusive, and healthy community.
## Our Standards
Examples of behavior that contributes to a positive environment for our
community include:
- Demonstrating empathy and kindness toward other people
- Being respectful of differing opinions, viewpoints, and experiences
- Giving and gracefully accepting constructive feedback
- Accepting responsibility and apologizing to those affected by our mistakes,
and learning from the experience
- Focusing on what is best not just for us as individuals, but for the overall
community
Examples of unacceptable behavior include:
- The use of sexualized language or imagery, and sexual attention or advances of
any kind
- Trolling, insulting or derogatory comments, and personal or political attacks
- Public or private harassment
- Publishing other's private information, such as a physical or email address,
without their explicit permission
- Other conduct which could reasonably be considered inappropriate in a
professional setting
## Enforcement Responsibilities
Community leaders are responsible for clarifying and enforcing our standards of
acceptable behavior and will take appropriate and fair corrective action in
response to any behavior that they deem inappropriate, threatening, offensive,
or harmful.
Community leaders have the right and responsibility to remove, edit, or reject
comments, commits, code, wiki edits, issues, and other contributions that are
not aligned to this Code of Conduct, and will communicate reasons for moderation
decisions when appropriate.
## Scope
This Code of Conduct applies within all community spaces, and also applies when
an individual is officially representing the community in public spaces.
Examples of representing our community include using an official e-mail address,
posting via an official social media account, or acting as an appointed
representative at an online or offline event.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported to the community leaders responsible for enforcement at
[contact@memgraph.com](contact@memgraph.com). All complaints will be reviewed
and investigated promptly and fairly.
All community leaders are obligated to respect the privacy and security of the
reporter of any incident.
## Enforcement Guidelines
Community leaders will follow these Community Impact Guidelines in determining
the consequences for any action they deem in violation of this Code of Conduct:
### 1. Correction
**Community Impact**: Use of inappropriate language or other behavior deemed
unprofessional or unwelcome in the community.
**Consequence**: A private, written warning from community leaders, providing
clarity around the nature of the violation and an explanation of why the
behavior was inappropriate. A public apology may be requested.
### 2. Warning
**Community Impact**: A violation through a single incident or series of
actions.
**Consequence**: A warning with consequences for continued behavior. No
interaction with the people involved, including unsolicited interaction with
those enforcing the Code of Conduct, for a specified period of time. This
includes avoiding interactions in community spaces as well as external channels
like social media. Violating these terms may lead to a temporary or permanent
ban.
### 3. Temporary Ban
**Community Impact**: A serious violation of community standards, including
sustained inappropriate behavior.
**Consequence**: A temporary ban from any sort of interaction or public
communication with the community for a specified period of time. No public or
private interaction with the people involved, including unsolicited interaction
with those enforcing the Code of Conduct, is allowed during this period.
Violating these terms may lead to a permanent ban.
### 4. Permanent Ban
**Community Impact**: Demonstrating a pattern of violation of community
standards, including sustained inappropriate behavior, harassment of an
individual, or aggression toward or disparagement of classes of individuals.
**Consequence**: A permanent ban from any sort of public interaction within the
community.
## Attribution
This Code of Conduct is adapted from the Contributor Covenant, version 2.1,
available at
[https://www.contributor-covenant.org/version/2/1/code_of_conduct.html](https://www.contributor-covenant.org/version/2/1/code_of_conduct.html).
Community Impact Guidelines were inspired by [Mozilla's code of conduct
enforcement ladder][mozilla coc].

# How to contribute?
This is a general purpose guide for contributing to Memgraph. We're still
working out the kinks to make contributing to this project as easy and
transparent as possible, but we're not quite there yet. Hopefully, this document
makes the process for contributing clear and answers some questions that you may
have.

## Open development
All work on Memgraph is done via [GitHub](https://github.com/memgraph/memgraph).
Both core team members and external contributors send pull requests which go
through the same review process.
## Branch organization
Most pull requests should target the [`master
branch`](https://github.com/memgraph/memgraph/tree/master). We only use separate
branches for developing new features and fixing bugs before they are merged with
`master`. We do our best to keep `master` in good shape, with all tests passing.
Code that lands in `master` must be compatible with the latest stable release.
It may contain additional features but no breaking changes if it's not
absolutely necessary. We should be able to release a new minor version from the
tip of `master` at any time.
## Bugs & changes
### Where to find known issues?
We are using [GitHub Issues](https://github.com/memgraph/memgraph/issues) for
our public bugs. We keep a close eye on this and try to make it clear when we
have an internal fix in progress. Before filing a new task, try to make sure
your problem doesn't already exist.
### Proposing a change
If you intend to change the public API, or make any non-trivial changes to the
implementation, we recommend [filing an
issue](https://github.com/memgraph/memgraph/issues/new). This lets us reach an
agreement on your proposal before you put significant effort into it.
If you're only fixing a bug, it's fine to submit a pull request right away but
we still recommend to file an issue detailing what you're fixing. This is
helpful in case we don't accept that specific fix but want to keep track of the
issue.
### Your first pull request
Working on your first Pull Request? You can learn how from this free video
series:
**[How to Contribute to an Open Source Project on
GitHub](https://app.egghead.io/courses/how-to-contribute-to-an-open-source-project-on-github)**
If you decide to fix an issue, please be sure to check the comment thread in
case somebody is already working on a fix. If nobody is working on it at the
moment, please leave a comment stating that you intend to work on it so other
people don't accidentally duplicate your effort.
If somebody claims an issue but doesn't follow up for more than two weeks, it's
fine to take it over but you should still leave a comment.
### Sending a pull request
The core team is monitoring for pull requests. We will review your pull request
and either merge it, request changes to it, or close it with an explanation.
**Before submitting a pull request,** please make sure the following is done:
1. Fork [the repository](https://github.com/memgraph/memgraph) and create your
branch from `master`.
2. If you've fixed a bug or added code that should be tested, add tests!
3. Use the formatter `clang-format` for C/C++ code and `flake8` for Python code.
`clang-format` will automatically detect the `.clang-format` file in the root
directory while `flake8` can be used with the default configuration.
### Style guide
Memgraph uses the [Google Style
Guide](https://google.github.io/styleguide/cppguide.html) for C++ in most of its
code. You should follow them whenever writing new code.
## How to get in touch?
Aside from communicating directly via Pull Requests and Issues, the Memgraph
Community [Discord Server](https://discord.gg/memgraph) is the best place for
conversing with project maintainers and other community members.
## [Code of Conduct](https://github.com/memgraph/memgraph/blob/master/CODE_OF_CONDUCT.md)
Memgraph has adopted the [Contributor
Covenant](https://www.contributor-covenant.org/) as its Code of Conduct, and we
expect project participants to adhere to it. Please read [the full

## Licences
## :clipboard: Description
* [Community](release/LICENSE_COMMUNITY.md)
* [Enterprise](release/LICENSE_ENTERPRISE.md)
Memgraph is a streaming graph application platform that helps you wrangle your
streaming data, build sophisticated models that you can query in real-time, and
develop graph applications.
Memgraph directly connects to your streaming infrastructure. You can ingest data
from sources like Kafka, SQL, or plain CSV files. Memgraph provides a standard
interface to query your data with Cypher, a widely-used and declarative query
language that is easy to write, understand and optimize for performance. This is
achieved by using the property graph data model, which stores data in terms of
objects, their attributes, and the relationships that connect them. This is a
natural and effective way to model many real-world problems without relying on
complex SQL schemas.
Memgraph is implemented in C/C++ and leverages an in-memory first architecture
to ensure that you’re getting the best possible performance consistently and
without surprises. It’s also ACID-compliant and highly available.

support and services to you only if you accept and agree to be bound by the terms and conditions in this Memgraph
Enterprise Licence Agreement (the “Agreement”). By signing an Order Document (as defined below), which is subject to and
part of this Agreement, installing and using the Software or by downloading a trial version of the Software, you agree
to be bound by the terms of this Agreement.
Memgraph Enterprise Trial Users: If you receive free of charge trial access to the Software, you are deemed a

set forth in Section 3.2 below in respect of your use of such Software.
1. DEFINITIONS.
1.1. “Applicable Laws” means (i) all applicable laws, statutes and regulations, and (ii) regulatory policies,
guidelines and industry codes (in each case having the force of law), which apply to the provisions of the
Software and Services and this Agreement.
1.2. “Confidential Information” means all information disclosed by a party (“Disclosing Party”) to the other party
(“Receiving Party”), whether orally or in writing, that is designated as confidential or that reasonably should

Software and Services; and Confidential Information of each party includes the terms and conditions of this
Agreement and all Orders (including pricing), as well as business and marketing plans, technology and technical
information, product plans and designs, and business processes disclosed by such party. However, Confidential
Information does not include any information that (i) is or becomes generally known to the public without
breach of any obligation owed to the Disclosing Party, (ii) was known to the Receiving Party prior to its
disclosure by the Disclosing Party without breach of any obligation owed to the Disclosing Party, (iii) is
received from a third party without breach of any obligation owed to the Disclosing Party, or (iv) was

Protection Act 2018; the Privacy and Electronic Communications Directive 2002/58/EC (as updated by Directive
2009/136/EC); and the Privacy and Electronic Communications Regulations 2003 (SI 2003/2426), in each case as
amended.

binary executable, intermediate or other form.
1.6. “Effective Date” means the date on which you execute this Agreement.
1.7. “Order Document” or “Order” means, as applicable: (i) in the case of a Trial Licence, the Memgraph trial
registration form available on Memgraph’s website; or (ii) in any other case, an order form that is submitted

this Agreement and that specifies the Software and/or Services ordered by Customer, as well as the specific
terms and conditions, for that particular transaction.

and bug fixes for the Software that may be provided to Customer by Memgraph pursuant to the terms of this
Agreement.

of the Software on Customer’s behalf pursuant to the terms of this Agreement.

Software after Customer accepts an Order. Unless otherwise stated in an Order, Customer is solely responsible
for installing Software on Customer’s own computer equipment. In some instances, Customer’s purchasing
relationship exists solely between Customer and an authorised reseller of Memgraph’s Software and Services
(a “Reseller”), in which case Sections 5.1-5.3 (Fees and Payment) will be inapplicable to such Order(s), and
the Reseller shall be responsible for submitting Orders and the appropriate payment method therewith to
Memgraph. An Order is not binding until Memgraph accepts and countersigns the Order.
2.2. Support. Memgraph will use commercially reasonable efforts to provide Support to Customer in accordance with
Memgraph’s then-current terms and conditions set forth at
https://download.memgraph.com/legal/memgraph-support-terms-and-conditions.pdf at the support tier stated in the
applicable Order. The Support terms and conditions are subject to change at Memgraph’s discretion; however,
Memgraph will not materially reduce the level of Support during a Subscription Term for which Fees have been
paid.
3. LICENCE GRANTS; RESTRICTIONS AND PROPRIETARY RIGHTS.
Customer’s licence and access rights and benefits, and Memgraph’s obligations to Customer, will vary depending on the
product and the type of licence Memgraph is granting. If you purchased a licence to Memgraph Software, your licence will
be subject to certain use and/or capacity restrictions, as identified on the applicable Order Document.
3.1. Enterprise Software Licence. In consideration of the Fees paid hereunder and subject to the terms of this
Agreement and the applicable Order, Memgraph grants Customer a world-wide, non-exclusive, non-transferable,
non-sublicensable, and limited licence during the applicable Subscription Term, to download, access, install
and use the Enterprise Software up to the maximum capacity (“Licensed Capacity”), and subject to the usage
rules, specified in the applicable Order Document, and to use Documentation solely for Customer’s internal
business purposes in connection with the operation of the Enterprise Software.
3.2. Enterprise Trial Licence. If the Customer downloads, accesses, installs or uses the Software under a trial
licence (“Trial Licence”), then Customer may use one (1) copy of the Software in accordance with the terms and
conditions of this Agreement for a thirty (30) day period, or such longer trial period represented by the
applicable licence key issued by or expressly authorised by Memgraph (the “Trial Period”). Trial Licences are
permitted solely for Customer’s evaluation use to determine whether to purchase a Subscription to the Software.
Customer may not use a Trial Licence for any other purpose. At the end of the Trial Period, the Trial Licence
will expire and this Agreement will terminate as to such Trial Licence and continue to apply to any subsequent
Subscription or use of the Software. If Customer decides not to obtain a Subscription upon expiration of the
Trial Period, it will promptly cease using and will delete the Software from its computer systems. Memgraph has
the right to terminate a Trial Licence at any time for any reason.
3.3. Limited right to modify the Software. In consideration of the Fees paid hereunder and subject to the terms of
this Agreement and the applicable Order, Memgraph grants Customer a licence to: (i) create, compile and test
Derivative Works; (ii) use Derivative Works solely for Customer’s internal business purposes; and (iii)
distribute Derivative Works back to Memgraph for potential incorporation into Memgraph’s maintained code base
at its sole discretion.
3.4. NO OBLIGATIONS. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT OR IN ANY ORDER DOCUMENT, MEMGRAPH
WILL HAVE NO WARRANTY, INDEMNITY, SUPPORT, OR SERVICE LEVEL, OBLIGATIONS WITH RESPECT TO ANY ENTERPRISE TRIAL,
OR OTHER NO-CHARGE SOFTWARE (INCLUDING TOOLS AND UTILITIES) LICENCES.
3.5. General Restrictions. Customer acknowledges that the Software, and its structure, organization, and source code,
constitute Memgraph’s and its suppliers’ valuable trade secrets, and that usage of the Software is subject to
the following restrictions:
3.5.1. Restrictions. Customer agrees not to, and not to authorize any third party to: (i) allow access or use
of the Software by anyone other than its Users; (ii) distribute, embed, sell, rent, transfer, lease,
lend, sublicense, loan, assign, pledge, grant a security interest in, or otherwise make the Software
accessible or available to any third party; except to the limited extent expressly provided in Section
3.5.2, use the Software in any service-bureau, timesharing, outsourcing or similar arrangement; (iii)
subject only to the limited rights set out in Section 3.3, modify, adapt, transform, derive, disassemble,
decompile, reverse engineer or otherwise attempt to derive the structure, sequence or organization of,
the Software or any portion thereof; (iv) remove or alter product identification, copyright, trademark or
other proprietary markings contained in or on the Software; (v) conduct any competitive analysis, publish
or share with any third party any results of any technical evaluation or tests performed on the Software,
or disclose Software features, errors or bugs to a third party without Memgraph’s prior written consent;
or (vi) engage in any act designed to circumvent any restriction set forth in this Agreement, in the
Software, or in an Order, including but not limited to restrictions related to Licensed Capacity.
3.5.2. Internal Use Licences; Users. The Software is licensed for Customer’s internal business use and not for
distribution or use by third parties. For clarity, however, Customer may make available to third parties
any Customer-hosted services or other Customer applications or services that make use of or incorporate
the Software, provided and solely to the extent that (i) Customer’s application or hosted service adds
primary and significant functionality to the Software, (ii) Customer does not embed or otherwise
distribute the Software to third parties (iii) Customer does not provide third parties direct access to
operate or control the Software itself; and (iv) Customer at all times remains in compliance with the
terms of the applicable licence grants under this Agreement. Subject to the terms and conditions of this
Agreement, in addition to Customer’s employees, Customer may permit its independent contractors and
consultants (“Contractors”) to serve as Users. Customer will remain responsible for compliance by each of
its Users (including but not limited to any Contractor Users) with all of the terms and conditions of
this Agreement, and any use of the Software by any Contractors must be for the sole benefit of Customer.
3.6. Ownership; Reservation of Rights. This is an agreement for use of Memgraph Software and not an agreement for
sale. Customer acknowledges that it is obtaining only a limited right to use the Software on a licensed basis,
and that irrespective of any use of the words “purchase”, “sale” or like terms hereunder no ownership rights
are being conveyed to Customer. Customer agrees that Memgraph or its suppliers retain all right, title and
interest (including all patent, copyright, trade secret and other intellectual property rights) in and to the
Memgraph Software. Nothing in this Section shall be deemed as granting Memgraph ownership of Customer Data or
in any way impacting Customer’s ownership of Customer Data.
3.7. Third Party Code. The Software may contain or be provided with components which are licensed from third
parties, including components subject to the terms and conditions of “open source” software licences
(“Open Source Software”). Open Source Software may be identified in the Software, Documentation, or in a list
of the Open Source Software provided to you upon your written request. To the extent required by the licence
that accompanies the Open Source Software, the terms of such licence will apply in lieu of the terms of this
Agreement with respect to such Open Source Software, including, without limitation, any provisions governing
access to source code, modification, or reverse engineering.
3.8. IP Ownership. The Parties agree that, save as otherwise provided in this Agreement, neither party shall gain, by
virtue of this Agreement, any rights of ownership or any other interest, right or title of copyrights, patents,
trade secrets, trademarks, or any other intellectual property rights owned by the other Party. Any and all new
works developed in the course of performing obligations pursuant to this Agreement and all new inventions,
innovations or ideas developed by a Party in the course of performance of its activities under this Agreement,
will belong to that Party who develops the same. Notwithstanding anything to the contrary in this Section, the
Parties understand and agree that any and all proprietary materials developed by a Party prior to this
Agreement and any modifications, enhancements, improvements or inventions made to such proprietary materials
shall be owned by that Party, regardless of which Party prepared or developed such modifications, enhancements,
improvements or inventions.
3.9. License-back of Derivate Works. If Customer elects, at its sole discretion, to distribute Derivative Works
back to Memgraph for potential incorporation into Memgraph’s maintained code base, Customer grants Memgraph
(without any restrictions, limitations or requirement of remuneration) a worldwide, non-exclusive, fully
paid-up, royalty-free, perpetual, irrevocable, transferable and sublicensable licence to use, exploit, modify,
make derivative works of, commercialise, distribute and otherwise exploit such Derivative Works.
4. CUSTOMER DATA; OBLIGATIONS OF CUSTOMER AND MEMGRAPH.
4.1. Customer shall retain all of its rights, title, and interest in and to its intellectual property rights in
Customer Data. Customer grants to Memgraph a non-exclusive, worldwide, limited-term licence solely to host,
copy, transmit and display Customer Data as reasonably necessary for Memgraph to support Customer’s use of the
Software, to ensure the security of and to administrate the Software, and to deliver Services in accordance
with this Agreement or as otherwise outlined in https://memgraph.com/legal/privacy-policy/.
4.2. Protection of Customer Data. Memgraph will maintain appropriate administrative, physical, and technical
safeguards, consistent with generally prevailing industry standards, for protection of the security,
confidentiality, and integrity of Customer Data, as described in the Documentation. Those safeguards will
include, but will not be limited to, measures for preventing access, use, modification, or disclosure of
Customer Data by Memgraph personnel, except as permitted by this Agreement.
4.3. Personal data. Both parties will comply with all applicable requirements of the Data Protection Legislation.
This section 4.3 is in addition to, and does not relieve, remove or replace, a party’s obligations under the
Data Protection Legislation. Notwithstanding the foregoing, the parties acknowledge that, in the ordinary
course of providing the Services, Memgraph shall not process personal data (as defined in the Data Protection
Legislation) on behalf of the Customer. In the event that the Customer requires Memgraph to process personal
data on its behalf, it shall notify Memgraph and the parties shall execute such additional terms as necessary
to comply with applicable Data Protection Legislation.
5. FEES AND PAYMENT.
5.1. Fees. Customer will pay Memgraph the fees for the Licences and Services as set forth in the applicable Order (
“Fees”). Customer acknowledges and agrees that if Customer’s use of the Software exceeds the Licensed Capacity
set forth on the applicable Orders or otherwise requires the payment of additional fees (per the terms of this
Agreement), Customer shall be invoiced for such usage and Customer agrees to pay the additional fees in
accordance with this Section. Notwithstanding the terms of Section 5.4 below (Reconciliation), Customer
acknowledges and agrees that it is obligated to ensure that its Software usage does not exceed the Licensed Capacity
and to promptly notify Memgraph of any such excess usage no more than thirty (30) days from the last day of the
calendar month during which such excess usage occurred.
5.2. Payment Terms. Except as otherwise specifically set forth on an Order Document, all fees are due and payable
within thirty days after the date of invoice. Renewal Fees for any renewal Subscription Term (if purchased by
Customer) will be due and payable within thirty (30) days of expiration of the then-current term. If Fees are
not paid when due, or in the event of other breach of this Agreement, Customer shall discontinue use of the
Software and Memgraph may suspend its performance, including its delivery of technical support of the Software
or other Services without further notice and without penalty. All Orders (including multi-year Subscriptions
with annual payment schedules) are non-cancellable and all amounts paid are non-refundable, unless otherwise
expressly set forth herein. Any invoiced amount not received by the due date will accrue late interest at the
rate of 1.5% of the outstanding balance per month, or the maximum rate permitted by applicable law, whichever
is lower.
5.3. Taxes. Fees are exclusive of taxes. Customer will pay any sales, use, value added, duties, fees and other
governmental assessments or charges arising out of this Agreement and the transactions contemplated herein.
Customer will make all payments free and clear of, and without reduction for, any withholding taxes.
5.4. Reconciliation. At Memgraph’s request from time to time, not exceeding once per quarter, Customer will provide
Memgraph with a report detailing its use of the Software, including its non-production and/or production use
and using the self-monitoring capabilities of the Software or other means, and Memgraph may inspect Customer’s
records related to such report not more frequently than annually to ensure payment of Fees. Any on-site review
will be conducted during regular business hours at Customer’s offices. The parties will use reasonable efforts
to promptly resolve any discrepancies between licensed usage and actual usage.
6. APPLICABLE LAWS.
6.1. Each Party shall perform this Agreement in accordance with all Applicable Laws. Without prejudice to the
foregoing, each Party shall:
6.1.1. comply with all Applicable Laws relating to anti-bribery, anti-corruption, anti-slavery and human
trafficking, including the Bribery Act 2010 and the Modern Slavery Act 2015
(the “Relevant Requirements”);
6.1.2. have and maintain in place throughout the Term its own policies and procedures, including adequate
procedures under the Bribery Act 2010, to ensure compliance with the Relevant Requirements, and will
enforce them where appropriate;
6.1.3. (if not prohibited by law or regulation from doing so) promptly report to the other Party any request or
demand for any undue financial or other advantage of any kind received by the reporting Party in
connection with the performance of this Agreement; and
6.1.4. (if not prohibited by law or regulation from doing so) notify the other Party (and email shall be
sufficient for this purpose) as soon as it becomes aware of any actual or suspected slavery or human
trafficking in a supply chain which has a connection with this Agreement.
7. REPRESENTATIONS AND WARRANTIES.
7.1. Mutual Representations and Warranties. Each Party represents and warrants to the other that: (i) it is a
corporation lawfully incorporated and validly existing pursuant to the laws of its place of incorporation;
(ii) it has all requisite power and authority, corporate or otherwise, to execute, deliver and perform its
obligations under this Agreement; and (iii) this Agreement constitutes its legal, valid and binding obligations
and may be enforced against it.
7.2. Limited Memgraph Warranty. Memgraph warrants that the Software, when used as permitted hereunder and in
accordance with the applicable Documentation, will operate in all material respects as described in the
applicable Documentation, and that the Services will be provided in a professional manner consistent with
industry standards.
7.3. Limitations; Remedy. Memgraph does not warrant that the Software or the Services will be error-free,
uninterrupted or meet Customer’s specific requirements or that performance of the Services will be
uninterrupted. Memgraph will have no warranty obligation under Section 7.2 for Customer’s misuse or failure to
use the Software in accordance with its Documentation or this Agreement. Customer’s sole and exclusive remedy,
and Memgraph’s sole and exclusive obligation, for breach of warranty will be (i) during the thirty (30) day
period following initial Delivery of the Software under an Order, Memgraph’s correction of the program errors
that cause the breach of warranty, or if Memgraph cannot substantially correct such breach in a commercially
reasonable manner, a refund of the fees paid for the nonconforming Software (ii) during the remainder of the
relevant Subscription Term, Memgraph’s delivery of Support with respect to any such program errors. In the
event of a refund remedy, Customer’s licences and right to use the Software or receive Services will end. In
the event of any noticed breach of warranty with respect to Services, Memgraph’s sole and exclusive obligation
shall be the re-performance of the deficient Services.
7.4. Disclaimer. THIS SECTION 7 IS A LIMITED WARRANTY AND, EXCEPT EXPRESSLY AS SET FORTH IN SECTION 7.2,
THE SOFTWARE, INCLUDING WITHOUT LIMITATION THE THIRD-PARTY CODE, AND ALL SERVICES ARE PROVIDED “AS IS”.
MEMGRAPH MAKES NO OTHER WARRANTIES OR REPRESENTATIONS, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, AND DISCLAIMS
ALL IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.
8. INDEMNIFICATION.
8.1. By Memgraph. Memgraph will defend against any action against Customer brought by a third party to the extent the
action is based on a claim that the Software infringes a third party’s patent, copyright or trademark
(a “Claim”) and indemnify Customer from the damages, liabilities, costs and expenses (including reasonable
attorneys’ fees) awarded against Customer or agreed in settlement by Customer resulting from such Claim. If
your use of the Software is (or in Memgraph’s opinion likely to be) enjoined, then Memgraph may, at its own
expense and at its option: (i) substitute substantially similar functionality for the Software which renders
it non-infringing; (ii) procure for Customer the right to continue to use the Software; or if (i) and (ii) are
not commercially reasonable, terminate this Agreement and refund Customer any prepaid, unused (pro-rated) Fees
for the duration of the then-current Subscription Term. The foregoing obligations of Memgraph will not apply:
(i) if the Software is modified by any party other than Memgraph, but solely to the extent the alleged
infringement is caused by such modification; (ii) if the Software is used in combination with other products or
processes not provided or authorized by Memgraph, but solely to the extent the alleged infringement is caused
by such combination; (iii) use of any version or release of Software other than the most current version or
release made available to Customer by Memgraph, if its use would have avoided the infringement; (iv) any
unauthorized use of the Software. THIS SECTION 8.1 SETS FORTH MEMGRAPH’S SOLE LIABILITY AND CUSTOMER’S SOLE
AND EXCLUSIVE REMEDY WITH RESPECT TO ANY CLAIM OF INTELLECTUAL PROPERTY INFRINGEMENT.
8.2. By Customer. Customer will indemnify and hold Memgraph and its suppliers harmless against any claims,
liabilities, costs, and expenses (including reasonable attorneys’ fees) that Memgraph or its suppliers may
incur as a result of a third-party claim arising from or related to Customer Data, or misuse or unauthorised
use of the Software by Customer or any User.
8.3. Conditions. All defence and indemnity obligations under Sections 8.1 and 8.2 are conditioned on the indemnitee
(i) giving the indemnitor written notice of the relevant claim within thirty (30) days after the indemnitee
receives notice of the Claim (or sooner if required by applicable law); (ii) reasonably cooperating with the
indemnitor, at the indemnitor’s expense, in the defence of the claim; and (iii) giving the indemnitor sole
control of the defence and any settlement negotiations. The indemnitee may participate in the defence at its
expense.
9. LIMITATION OF LIABILITY.
9.1. TO THE EXTENT PERMITTED BY LAW, NEITHER MEMGRAPH NOR CUSTOMER SHALL BE LIABLE TO THE OTHER OR ANY THIRD PARTY
FOR LOST PROFITS (WHETHER DIRECT OR INDIRECT) OR LOSS OF USE OR DATA, SUBSTITUTE GOODS OR SERVICES, OR FOR
INCIDENTAL, CONSEQUENTIAL, PUNITIVE, SPECIAL OR EXEMPLARY DAMAGES (INCLUDING DAMAGE TO BUSINESS, REPUTATION OR
GOODWILL), OR INDIRECT DAMAGES OF ANY TYPE HOWEVER CAUSED, WHETHER BY BREACH OF WARRANTY, BREACH OF CONTRACT,
IN TORT (INCLUDING NEGLIGENCE) OR ANY OTHER LEGAL OR EQUITABLE CAUSE OF ACTION EVEN IF SUCH PARTY HAS BEEN
ADVISED OF SUCH DAMAGES IN ADVANCE OR IF SUCH DAMAGES WERE FORESEEABLE.
9.2. LIMITATIONS ON DIRECT DAMAGES. EXCEPT FOR ANY EXCLUDED CLAIMS AND ANY DAMAGES THAT CANNOT BE LIMITED UNDER
APPLICABLE LAW, IN NO EVENT WILL MEMGRAPH’S TOTAL AGGREGATE LIABILITY ARISING FROM OR RELATED TO THIS
AGREEMENT, EXCEED AN AMOUNT EQUAL TO THE TOTAL AMOUNT OF FEES PAID OR PAYABLE BY CUSTOMER TO MEMGRAPH UNDER
THIS AGREEMENT DURING THE TWELVE MONTHS PRECEDING THE CLAIM. THE FOREGOING LIMITATIONS SHALL NOT APPLY TO: (i)
PAYMENTS TO A THIRD PARTY ARISING FROM A PARTY’S OBLIGATIONS UNDER SECTION 8 (INDEMNIFICATION); (ii) BREACH BY
A PARTY OF SECTION 10 (CONFIDENTIAL INFORMATION), AND (iii) INFRINGEMENT BY A PARTY OF THE OTHER PARTY’S
INTELLECTUAL PROPERTY RIGHTS (COLLECTIVELY EXCLUSIONS (i)-(iii) ARE REFERRED TO AS THE “EXCLUDED CLAIMS”). WITH
RESPECT TO ANY EXCLUDED CLAIMS, MEMGRAPH’S TOTAL AGGREGATE LIABILITY SHALL IN NO EVENT EXCEED £1,000,000.
9.3. Nothing in this Agreement excludes the liability of Memgraph for death or personal injury caused by the
Supplier’s negligence; or for fraud or fraudulent misrepresentation.
10. CONFIDENTIALITY.
10.1. The Receiving Party will use the same degree of care that it uses to protect the confidentiality of its own
confidential information of like kind (but not less than reasonable care) to (i) not use any confidential
information of the Disclosing Party for any purpose outside the scope of this agreement and (ii) except as
otherwise authorized by the Disclosing Party in writing, limit access to confidential information of the
Disclosing Party to those of its and its affiliates’ employees and contractors who need that access for
purposes consistent with this agreement and who have signed confidentiality agreements with the receiving party
containing protections not materially less protective of the confidential information than those herein.
Neither party will disclose the terms of this agreement or any Orders to any third-party other than its
affiliates, legal counsel, and accountants without the other party’s prior written consent, provided that a
party that makes any such disclosure to its affiliate, legal counsel or accountants will remain responsible for
such affiliate’s, legal counsel’s, or accountant’s compliance with this “Confidentiality” section.
10.2. Compelled Disclosure. The Receiving Party may disclose confidential information of the Disclosing Party to the
extent compelled by law to do so, provided the Receiving Party gives the Disclosing Party prior notice of the
compelled disclosure (to the extent legally permitted) and reasonable assistance, at the Disclosing Party’s
cost, if the Disclosing Party wishes to contest the disclosure. If the receiving party is compelled by law to
disclose the Disclosing Party’s confidential information as part of a civil proceeding to which the Disclosing
Party is a party, and the Disclosing Party is not contesting the disclosure, the Disclosing Party will
reimburse the Receiving Party for its reasonable cost of complying and providing secure access to that
confidential information.
11. TERMINATION.
11.1. Term. The term (“Term”) of this Agreement will commence on the Effective Date and continue until all
Subscriptions, licence terms and Orders expire, unless earlier terminated in accordance with this Section 11.
11.2. Termination for Cause. In the event of a material breach of this Agreement (excluding any breaches for which an
exclusive remedy is expressly provided), the non-breaching party may terminate this Agreement if such breach
is not cured within thirty (30) days after written notice thereof (except that for a breach of Section 3.5
(“General Restrictions”), there will be no cure period). For clarity, material breach of this Agreement
includes, but is not limited to, failure to timely pay amounts due hereunder, exceeding the scope of any
Licence granted hereunder (including the Licensed Capacity), violating the Licence restrictions, breach of
Section 6.1 and failing to protect the other party’s Confidential Information.
11.3. Without affecting any other right or remedy available to it, and to the fullest extent permitted by applicable
law, either party may terminate this Agreement with immediate effect by giving written notice to the other
party if the other party:
11.3.1. suspends, or threatens to suspend, payment of its debts or is unable to pay its debts as they fall due or
admits inability to pay its debts or is deemed unable to pay its debts within the meaning of section 123
of the Insolvency Act 1986, as if the words “it is proved to the satisfaction of the court” did not
appear in sections 123(1)(e) or 123(2) of the Insolvency Act 1986; or
11.3.2. the other party commences negotiations with all or any class of its creditors with a view to rescheduling
any of its debts, or makes a proposal for or enters into any compromise or arrangement with its creditors
other than for the sole purpose of a scheme for a solvent amalgamation of that other party with one or
more other companies or the solvent reconstruction of that other party; or
11.3.3. a petition is filed, a notice is given, a resolution is passed, or an order is made, for or in connection
with the winding up of that other party other than for the sole purpose of a scheme for a solvent
amalgamation of that other party with one or more other companies or the solvent reconstruction of that
other party; or
11.3.4. an application is made to court, or an order is made, for the appointment of an administrator, or if a
notice of intention to appoint an administrator is given or if an administrator is appointed, over the
other party; or
11.3.5. the holder of a qualifying floating charge over the assets of that other party has become entitled to
appoint or has appointed an administrative receiver; or
11.3.6. a person becomes entitled to appoint a receiver over the assets of the other party or a receiver is
appointed over the assets of the other party; or
11.3.7. a creditor or encumbrancer of the other party attaches or takes possession of, or a distress, execution,
sequestration or other such process is levied or enforced on or sued against, the whole or any part of
the other party’s assets and such attachment or process is not discharged within 30 days; or
11.3.8. any event occurs, or proceeding is taken, with respect to the other party in any jurisdiction to which
it is subject that has an effect equivalent or similar to any of the events mentioned in clause 11.3.1 to
clause 11.3.7 (inclusive); or
11.3.9. the other party suspends or ceases, or threatens to suspend or cease, carrying on all or a substantial
part of its business.
11.4. Effect of Termination. Upon the termination of this Agreement: (i) all licences will terminate; (ii) Customer
will immediately discontinue all use of the affected Software and erase all other tangible embodiments of
Memgraph Confidential Information in Customer’s possession or control, and promptly certify the same to
Memgraph; (iii) Memgraph may immediately cease providing the Services; (iv) (subject to this Section),
Memgraph will return or delete all tangible embodiments of Customer Confidential Information in Memgraph’s
possession or control; and (v) Sections 1 (“Definitions”), 3.5 (“General Restrictions”), 3.6 (“Ownership;
Reservation of Rights”), 5 (“Fees and Payment”), 7.3 (“Limitations”), 7.4 (“Disclaimer”), 8
(“Indemnification”), 9 (“Limitation of Liability”), 10 (“Confidentiality”), 11.4 (“Effect of Termination”),
and 12 (“Miscellaneous”) will survive. If a party’s file retention policies or a valid legal order provides
for backup or archival copies of files to be retained, such party will notify the other party of such policy
or order, protect the other party’s Confidential Information as required hereunder, and permanently erase,
delete, or destroy such Confidential Information as soon as permissible under such policy or order.
12. MISCELLANEOUS.
12.1. Assignment. This Agreement will bind and inure to the benefit of each party’s permitted successors and assigns.
Memgraph may assign this Agreement to any affiliate or in connection with a merger, reorganization,
acquisition, or other transfer of all or substantially all of Memgraph’s assets or voting securities. Customer
may not assign or transfer this Agreement, in whole or in part, without Memgraph’s written consent except that
Customer may assign its rights and obligations under this Agreement, in whole but not in part, without
Memgraph’s written consent in connection with any merger, consolidation, sale of all or substantially all of
Customer’s assets or voting stock, or any other similar transaction provided that: (i) the assignee is not a
direct competitor of Memgraph; (ii) Customer provides prompt written notice of such assignment to Memgraph;
(iii) the assignee is capable of fully performing Customer’s obligations under this Agreement; and (iv) the
assignee agrees to be bound by the terms and conditions of this Agreement. Any attempt to transfer or assign
this Agreement without such written consent will be null and void.Force Majeure. Memgraph shall have no
liability to the Customer under this Agreement if it is prevented from or delayed in performing its obligations
under this Agreement, or from carrying on its business, by acts, events, omissions or accidents beyond its
reasonable control, including strikes, lock-outs or other industrial disputes (whether involving the workforce
of Memgraph or any other party), failure of a utility service or transport or telecommunications network, act
of God, war, pandemic, riot, civil commotion, malicious damage, compliance with any law or governmental order,
rule, regulation or direction, accident, breakdown of plant or machinery, fire, flood, storm or default of
suppliers or subcontractors, provided that the Customer is notified of such an event and its expected duration.
12.2. Governing Law. This Agreement and any dispute or claim arising out of or in connection with it or its subject
matter or formation (including non-contractual disputes or claims) shall be governed by and construed in
accordance with the law of England and Wales.
12.3. Jurisdiction. Each party irrevocably agrees that the courts of England and Wales shall have exclusive
jurisdiction to settle any dispute or claim arising out of or in connection with this Agreement or its subject
matter or formation (including non-contractual disputes or claims).
12.4. Severability; Waiver; Construction. If a court of competent jurisdiction adjudges any provision of this
Agreement to be invalid or unenforceable, the remaining provisions of this Agreement, if capable of substantial
performance, will continue in full force and effect without being impaired or invalidated in any way. The
parties agree to replace any invalid provision with a valid provision that most closely approximates the intent
and economic effect of the invalid provision. All waivers must be in writing. A party’s consent to, or waiver
of, enforcement of this Agreement on one occasion will not be deemed a waiver of any other provision or such
provision on any other occasion. In this Agreement, the word “including” means “including but not limited to.”
No presumption will operate in favour of or against any party as a result of its role in drafting this
Agreement.
12.5. Subcontractors. Memgraph may use the services of subcontractors in connection with its performance of this
Agreement, provided that Memgraph remains solely responsible for (i) compliance of any such subcontractor with
the terms of this Agreement and (ii) the overall performance of Memgraph as required under this Agreement.
12.6. Use of Aggregate Data. Customer agrees that Memgraph may collect, use and disclose quantitative data and
metadata derived from the use of the Software (i) for its own internal, statistical analysis, (ii) to develop
and improve the Software and (iii) to create and distribute reports and other materials regarding use of the
Software. For clarity, any such data collected, used, and disclosed will be in anonymized aggregate form only
and shall not identify Customer or its Users, or disclose any Customer Data.Independent Contractors. The
parties are independent contractors. No agency, partnership, franchise, joint venture, or employment
relationship is intended or created by this Agreement. Neither party has the power or authority to create or
assume any obligation, or make any representations or warranties, on behalf of the other party.
12.7. Publicity. Memgraph may, in conformity with Customer’s trademark usage guidelines, use Customer’s name and logo
in Memgraph’s sales and marketing materials, including in business presentations, Customer lists, and on
websites. Neither party will issue a press release regarding this Agreement without the other party’s prior
written consent. Neither party will disclose the terms of this Agreement to any third party, except as required
by law.
12.8. Notice. Any notice, consent, or waiver hereunder must be in writing, addressed to the attention of “Legal
Department” at the address set forth above, and delivered by personal delivery, reputable rapid courier, or
certified/registered mail, return receipt requested, and will be deemed given upon personal delivery, one (1)
day after deposit with an overnight domestic courier, two (2) days after deposit with an international courier,
or five (5) days after deposit in the certified or registered mail. A party may specify a new address by
providing notice to the other party in accordance with this Section.
12.9. Compliance with Law. Each party will comply with all applicable laws, regulations, and orders of any
governmental authority of competent jurisdiction in its performance under this Agreement, including but not
limited to those applicable to data collection and the privacy and security of personal information, including
trans-border data transfers and data breach notification requirements as required of each party by law.
12.10.Supremacy; Modification. This Agreement will prevail over any written instrument submitted by Customer; the
terms of any purchase order, acknowledgement, or similar document submitted by Customer to Memgraph will have
no effect. If the express terms of an Order Document conflict with this Agreement, the terms on the Order
Document will prevail, but only with respect to that Order Document. This Agreement cannot be varied or
supplemented by course of dealing or by usage of trade. All modifications or amendments to this Agreement must
be in writing and signed by both parties, except that subsequent renewals and purchases of additional Licensed
Capacity can be procured by payment against an issued invoice as set forth in Section 5 (“Fees and Payment”)
above.
12.11.No Third Party Beneficiaries. This Agreement is not intended and shall not be construed to give any third party
any interest or rights with respect to or in connection with any agreement or provision herein, except as
expressly provided for in this Agreement.
12.12.Entire Agreement. This Agreement in its original English text, sets forth the complete, exclusive, and final
agreement of the parties concerning the subject matter hereof, supersedes, replaces, and merges all prior and
contemporaneous agreements, communications, and understandings, both
written and oral, between them concerning the subject matter hereof. This Agreement may be executed in
counterparts.

Creative Commons Legal Code
CC0 1.0 Universal
CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
HEREUNDER.
Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator
and subsequent owner(s) (each and all, an "owner") of an original work of
authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for
the purpose of contributing to a commons of creative, cultural and
scientific works ("Commons") that the public can reliably and without fear
of later claims of infringement build upon, modify, incorporate in other
works, reuse and redistribute as freely as possible in any form whatsoever
and for any purposes, including without limitation commercial purposes.
These owners may contribute to the Commons to promote the ideal of a free
culture and the further production of creative, cultural and scientific
works, or to gain reputation or greater distribution for their Work in
part through the use and efforts of others.
For these and/or other purposes and motivations, and without any
expectation of additional consideration or compensation, the person
associating CC0 with a Work (the "Affirmer"), to the extent that he or she
is an owner of Copyright and Related Rights in the Work, voluntarily
elects to apply CC0 to the Work and publicly distribute the Work under its
terms, with knowledge of his or her Copyright and Related Rights in the
Work and the meaning and intended legal effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be
protected by copyright and related or neighboring rights ("Copyright and
Related Rights"). Copyright and Related Rights include, but are not
limited to, the following:
i. the right to reproduce, adapt, distribute, perform, display,
communicate, and translate a Work;
ii. moral rights retained by the original author(s) and/or performer(s);
iii. publicity and privacy rights pertaining to a person's image or
likeness depicted in a Work;
iv. rights protecting against unfair competition in regards to a Work,
subject to the limitations in paragraph 4(a), below;
v. rights protecting the extraction, dissemination, use and reuse of data
in a Work;
vi. database rights (such as those arising under Directive 96/9/EC of the
European Parliament and of the Council of 11 March 1996 on the legal
protection of databases, and under any national implementation
thereof, including any amended or successor version of such
directive); and
vii. other similar, equivalent or corresponding rights throughout the
world based on applicable law or treaty, and any national
implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention
of, applicable law, Affirmer hereby overtly, fully, permanently,
irrevocably and unconditionally waives, abandons, and surrenders all of
Affirmer's Copyright and Related Rights and associated claims and causes
of action, whether now known or unknown (including existing as well as
future claims and causes of action), in the Work (i) in all territories
worldwide, (ii) for the maximum duration provided by applicable law or
treaty (including future time extensions), (iii) in any current or future
medium and for any number of copies, and (iv) for any purpose whatsoever,
including without limitation commercial, advertising or promotional
purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
member of the public at large and to the detriment of Affirmer's heirs and
successors, fully intending that such Waiver shall not be subject to
revocation, rescission, cancellation, termination, or any other legal or
equitable action to disrupt the quiet enjoyment of the Work by the public
as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason
be judged legally invalid or ineffective under applicable law, then the
Waiver shall be preserved to the maximum extent permitted taking into
account Affirmer's express Statement of Purpose. In addition, to the
extent the Waiver is so judged Affirmer hereby grants to each affected
person a royalty-free, non transferable, non sublicensable, non exclusive,
irrevocable and unconditional license to exercise Affirmer's Copyright and
Related Rights in the Work (i) in all territories worldwide, (ii) for the
maximum duration provided by applicable law or treaty (including future
time extensions), (iii) in any current or future medium and for any number
of copies, and (iv) for any purpose whatsoever, including without
limitation commercial, advertising or promotional purposes (the
"License"). The License shall be deemed effective as of the date CC0 was
applied by Affirmer to the Work. Should any part of the License for any
reason be judged legally invalid or ineffective under applicable law, such
partial invalidity or ineffectiveness shall not invalidate the remainder
of the License, and in such case Affirmer hereby affirms that he or she
will not (i) exercise any of his or her remaining Copyright and Related
Rights in the Work or (ii) assert any associated claims and causes of
action with respect to the Work, in either case contrary to Affirmer's
express Statement of Purpose.
4. Limitations and Disclaimers.
a. No trademark or patent rights held by Affirmer are waived, abandoned,
surrendered, licensed or otherwise affected by this document.
b. Affirmer offers the Work as-is and makes no representations or
warranties of any kind concerning the Work, express, implied,
statutory or otherwise, including without limitation warranties of
title, merchantability, fitness for a particular purpose, non
infringement, or the absence of latent or other defects, accuracy, or
the present or absence of errors, whether or not discoverable, all to
the greatest extent permissible under applicable law.
c. Affirmer disclaims responsibility for clearing rights of other persons
that may apply to the Work or any use thereof, including without
limitation any person's Copyright and Related Rights in the Work.
Further, Affirmer disclaims responsibility for obtaining any necessary
consents, permissions or other rights required for any use of the
Work.
d. Affirmer understands and acknowledges that Creative Commons is not a
party to this document and has no duty or obligation with respect to
this CC0 or use of the Work.

copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the
Work and such Derivative Works in Source or Object form.
3. Grant of Patent License. Subject to the terms and conditions of

worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works

attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and

pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.

TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
1. Definitions.
"License" shall mean the terms and conditions for use, reproduction,
and distribution as defined by Sections 1 through 9 of this document.
"Licensor" shall mean the copyright owner or entity authorized by
the copyright owner that is granting the License.
"Legal Entity" shall mean the union of the acting entity and all
other entities that control, are controlled by, or are under common
control with that entity. For the purposes of this definition,
"control" means (i) the power, direct or indirect, to cause the
direction or management of such entity, whether by contract or

ZLIB DATA COMPRESSION LIBRARY
zlib 1.2.11 is a general purpose data compression library. All the code is
thread safe. The data format used by the zlib library is described by RFCs
(Request for Comments) 1950 to 1952 in the files
http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
rfc1952 (gzip format).
All functions of the compression library are documented in the file zlib.h
(volunteer to write man pages welcome, contact zlib@gzip.org). A usage example
of the library is given in the file test/example.c which also tests that
the library is working correctly. Another example is given in the file
test/minigzip.c. The compression library itself is composed of all source
files in the root directory.
To compile all files and run the test program, follow the instructions given at
the top of Makefile.in. In short "./configure; make test", and if that goes
well, "make install" should work for most flavors of Unix. For Windows, use
one of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use
make_vms.com.
Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant
<info@winimage.com> for the Windows DLL version. The zlib home page is
http://zlib.net/ . Before reporting a problem, please check this site to
verify that you have the latest version of zlib; otherwise get the latest
version and check whether the problem still exists or not.
PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.
Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
issue of Dr. Dobb's Journal; a copy of the article is available at
http://marknelson.us/1997/01/01/zlib-engine/ .
The changes made in version 1.2.11 are documented in the file ChangeLog.
Unsupported third party contributions are provided in directory contrib/ .
zlib is available in Java using the java.util.zip package, documented at
http://java.sun.com/developer/technicalArticles/Programming/compression/ .
A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available
at CPAN (Comprehensive Perl Archive Network) sites, including
http://search.cpan.org/~pmqs/IO-Compress-Zlib/ .
A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is
available in Python 1.5 and later versions, see
http://docs.python.org/library/zlib.html .
zlib is built into tcl: http://wiki.tcl.tk/4610 .
An experimental package to read and write files in .zip format, written on top
of zlib by Gilles Vollant <info@winimage.com>, is available in the
contrib/minizip directory of zlib.
Notes for some targets:
- For Windows DLL versions, please see win32/DLL_FAQ.txt
- For 64-bit Irix, deflate.c must be compiled without any optimization. With
-O, one libpng test fails. The test works in 32 bit mode (with the -n32
compiler flag). The compiler bug has been reported to SGI.
- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works
when compiled with cc.
- On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is
necessary to get gzprintf working correctly. This is done by configure.
- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with
other compilers. Use "make test" to check your compiler.
- gzdopen is not supported on RISCOS or BEOS.
- For PalmOs, see http://palmzlib.sourceforge.net/
Acknowledgments:
The deflate format used by zlib was defined by Phil Katz. The deflate and
zlib specifications were written by L. Peter Deutsch. Thanks to all the
people who reported problems and suggested various improvements in zlib; they
are too numerous to cite here.

the Reseller shall be responsible for submitting Orders and the appropriate
payment method therewith to Memgraph. An Order is not binding until Memgraph

subject to certain use and/or capacity restrictions, as identified on the
applicable Order Document.
3.1. Enterprise Software Licence. In consideration of the Fees paid hereunder
and subject to the terms of this Agreement and the applicable Order, Memgraph
grants Customer a world-wide, non-exclusive, non-transferable,
non-sublicenseable, and limited licence during the applicable Subscription
Term, to install, and use the Enterprise Software up to the maximum capacity

applicable Order Document, and to use Documentation solely for Customer's
internal business purposes in connection with operation of the Enterprise
Software.

Software under a trial licence ("Trial Licence"), then Customer may use one (1)
copy of the Software in accordance with the terms and conditions of this
Agreement for a thirty (30) day period, or such longer trial period represented
by the applicable licence key issued by or expressly authorised by Memgraph
(the "Trial Period"). Trial Licences are permitted solely for Customer's
evaluation use to determine whether to purchase a Subscription to the Software.
Customer may not use a Trial Licence for any other purpose. At the end of the
Trial Period, the Trial Licence will expire (and this Agreement will terminate
as to such Licence and continue to apply to any subsequent Subscription or use
of the Software; if Customer decides not to obtain a Subscription upon
expiration of the Trial Period, it will promptly cease using and will delete
the Software from its computer systems. Memgraph has the right to terminate a
Trial Licence at any time for any reason.
3.3. NO OBLIGATIONS. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT
OR IN ANY ORDER DOCUMENT, MEMGRAPH WILL HAVE NO WARRANTY, INDEMNITY, SUPPORT,
OR SERVICE LEVEL, OBLIGATIONS WITH RESPECT TO ANY ENTERPRISE TRIAL, OR OTHER
NO-CHARGE SOFTWARE (INCLUDING TOOLS AND UTILITIES) LICENCES.
3.4. General Restrictions. Customer acknowledges that the Software, and its
structure, organization, and source code, constitute Memgraph's and its
suppliers' valuable trade secrets, and that usage of the Software is subject to
the following restrictions:
3.4.1. Restrictions. Customer agrees not to, and not to authorize any third
party to: (i) allow access or use of the Software by anyone other than its
Users; (ii) distribute, embed, sell, rent, transfer, lease, lend, sublicense,
loan, assign, pledge, grant a security interest in, or otherwise make the
Software accessible or available to any third party; except to the limited
extent expressly provided in Section 3.4.2, use the Software in any
service-bureau, timesharing, outsourcing or similar arrangement; or (iii)
disassemble, decompile, reverse engineer or otherwise attempt to derive the
structure, sequence or organization of source code or APIs; (iv) remove or
alter product identification, copyright, trademark or other proprietary
markings contained in or on the Software; (v) modify, adapt, recast, transform
or otherwise prepare a derivative work of the Software or portion thereof; (vi)

results of any technical evaluation or tests performed on the Software, or
disclose Software features, errors or bugs to a third party without Memgraph's
prior written consent; or (vii) engage in any act designed to circumvent any
restriction set forth in this Agreement, in the Software, or in an Order,
including but not limited to restrictions related to Licensed Capacity.
3.4.2. Internal Use Licences; Users. The Software is licensed for Customer's
internal business use and not for distribution or use by third parties. For
clarity, however, Customer may make available to third parties any
Customer-hosted services or other Customer applications or services that make
use of or incorporate the Software, provided and solely to the extent that (i)
Customer's application or hosted service adds primary and significant
functionality to the Software, (ii) Customer does not embed or otherwise
distribute the Software to third parties, (iii) Customer does not provide third
parties direct access to operate or control the Software itself; and (iv)
Customer at all times remains in compliance with the terms of the applicable
licence grants under this Agreement. Subject to the terms and conditions of
this Agreement, in addition to Customer's employees, Customer may permit its
independent contractors and consultants ("Contractors") to serve as Users.
Customer will remain responsible for compliance by each of its Users (including
but not limited to any Contractor Users) with all of the terms and conditions
of this Agreement, and any use of the Software by any Contractors must be for
the sole benefit of Customer.
3.5. Ownership; Reservation of Rights. This is an agreement for use of Memgraph
Software and not an agreement for sale. Customer acknowledges that it is
obtaining only a limited right to use the Software on a licensed basis, and
that irrespective of any use of the words "purchase", "sale" or like terms
hereunder no ownership rights are being conveyed to Customer. Customer agrees
that Memgraph or its suppliers retain all right, title and interest (including
all patent, copyright, trade secret and other intellectual property rights) in
and to the Memgraph Software. Nothing in this Section shall be deemed as
granting Memgraph ownership of Customer Data or in any way impacting Customer's
ownership of Customer Data.
3.6. Third Party Code. The Software may contain or be provided with components
which are licensed from third parties, including components subject to the
terms and conditions of "open source" software licences ("Open Source
Software"). Open Source Software may be identified in the Software,
Documentation, or in a list of the Open Source Software provided to you upon
your written request. To the extent required by the licence that accompanies
the Open Source Software, the terms of such licence will apply in lieu of the
terms of this Agreement with respect to such Open Source Software, including,
without limitation, any provisions governing access to source code,
modification, or reverse engineering.
3.7. IP Ownership. The Parties agree that neither party shall gain, by virtue
of this Agreement, any rights of ownership or any other interest, right or
title of copyrights, patents, trade secrets, trademarks, or any other
intellectual property rights owned by the other Party. Any and all new works
developed in the course of performing obligations pursuant to this Agreement
and all new inventions, innovations or ideas developed by a Party in the course
of performance of its activities under this Agreement, will belong to that
Party who develops the same. Notwithstanding anything to the contrary in this
Section, the Parties understand and agree that any and all proprietary
materials developed by a Party prior to this Agreement and any modifications,
enhancements, improvements or inventions made to such proprietary materials
shall be owned by that Party, regardless of which Party prepared or developed
such modifications, enhancements, improvements or inventions.
## 4. CUSTOMER DATA; OBLIGATIONS OF CUSTOMER AND MEMGRAPH.
4.1. Customer shall retain all of its rights, title, and interest in and to its
intellectual property rights in Customer Data. Customer grants to Memgraph a
non-exclusive, worldwide, limited-term licence solely to host, copy, transmit
and display Customer Data as reasonably necessary for Memgraph to support
Customer's use of the Software, to ensure the security of and to administrate
the Software, and to deliver Services in accordance with this Agreement or as
otherwise outlined in https://memgraph.com/legal/privacy-policy/.
4.2. Protection of Customer Data. Memgraph will maintain appropriate
administrative, physical, and technical safeguards, consistent with generally
prevailing industry standards, for protection of the security, confidentiality,
and integrity of Customer Data, as described in the Documentation. Those
safeguards will include, but will not be limited to, measures for preventing
access, use, modification, or disclosure of Customer Data by Memgraph
personnel, except as permitted by this Agreement.
4.3. Personal data. Both parties will comply with all applicable requirements
of the Data Protection Legislation. This section 4 is in addition to, and does
not relieve, remove or replace, a party's obligations under the Data Protection
Legislation. Notwithstanding the foregoing, the parties acknowledge that, in
the ordinary course of providing the Services, Memgraph shall not process
personal data (as defined in the Data Protection Legislation) on behalf of the
Customer. In the event that the Customer requires Memgraph to process personal
data on its behalf, it shall notify Memgraph and the parties shall execute such
terms as necessary under applicable law.
## 5. FEES AND PAYMENT.
5.1. Fees. Customer will pay Memgraph the fees for the Licences and Services as
set forth in the applicable Order ("Fees"). Customer acknowledges and agrees
that if Customer's use of the Software exceeds the Licensed Capacity set forth
on the applicable Orders or otherwise requires the payment of additional fees
(per the terms of this Agreement), Customer shall be invoiced for such usage
and Customer agrees to pay the additional fees in accordance with this Section.
Notwithstanding the terms of Section 5.4 below (Reconciliation), Customer
acknowledges and agrees that it is obligated to ensure that its Software usage
does not exceed the Licensed Capacity and to promptly notify Memgraph of any
such excess usage no more than thirty (30) days from the last day of the
calendar month during which such excess usage occurred.
5.2. Payment Terms. Except as otherwise specifically set forth on an Order
Document, all fees are due and payable within thirty days after the date of
invoice. Renewal Fees for any renewal Subscription Term (if purchased by
Customer) will be due and payable within thirty (30) days of expiration of the
then-current term. If Fees are not paid when due, or in the event of other
breach of this Agreement, Customer shall discontinue use of the Software and
Memgraph may suspend its performance, including its delivery of technical
support of the Software or other Services without further notice and without
penalty. All Orders (including multi-year Subscriptions with annual payment
schedules) are non-cancellable and all amounts paid are non-refundable, unless
otherwise expressly set forth herein. Any invoiced amount not received by the
due date will accrue late interest at the rate of 1.5% of the outstanding
balance per month, or the maximum rate permitted by applicable law, whichever
is lower.
5.3. Taxes. Fees are exclusive of taxes. Customer will pay any sales, use,
value added, duties, fees and other governmental assessments or charges arising
out of this Agreement and the transactions contemplated herein. Customer will
make all payments free and clear of, and without reduction for, any withholding
taxes.
5.4. Reconciliation. At Memgraph's request from time to time, not exceeding
once per quarter, Customer will provide Memgraph with a report detailing its
use of the Software, including its non-production and/or production use and
using the self-monitoring capabilities of the Software or other means, and
Memgraph may inspect Customer's records related to such report not more
frequently than annually to ensure payment of Fees. Any on-site review will be
conducted during regular business hours at Customer's offices. The parties will
use reasonable good faith efforts to promptly resolve any discrepancies between
licensed usage and actual usage.
## 6. APPLICABLE LAWS.
6.1. Each Party shall perform this Agreement in accordance with all Applicable
Laws. Without prejudice to the foregoing, each Party shall:
6.1.1. comply with all Applicable Laws relating to anti-bribery,
anti-corruption, anti-slavery and human trafficking, including the Bribery Act
2010 and the Modern Slavery Act 2015 (the "Relevant Requirements");
6.1.2. have and maintain in place throughout the Term its own policies and
procedures, including adequate procedures under the Bribery Act 2010, to ensure
compliance with the Relevant Requirements, and will enforce them where
appropriate;
6.1.3. (if not prohibited by law or regulation from doing so) promptly report
to the other Party any request or demand for any undue financial or other
advantage of any kind received by the reporting Party in connection with the
performance of this Agreement; and
6.1.4. (if not prohibited by law or regulation from doing so) notify the other
Party (and email shall be sufficient for this purpose) as soon as it becomes
aware of any actual or suspected slavery or human trafficking in a supply chain
which has a connection with this Agreement.
## 7. REPRESENTATIONS AND WARRANTIES.
7.1. Mutual Representations and Warranties. Each Party represents and warrants
to the other that: (i) it is a corporation lawfully incorporated and validly
existing pursuant to the laws of its place of incorporation; (ii) it has all
requisite power and authority, corporate or otherwise, to execute, deliver and
perform its obligations under this Agreement; and (iii) this Agreement
constitutes its legal, valid and binding obligations and may be enforced
against it.
7.2. Limited Memgraph Warranty; Remedies. Memgraph warrants that the Software,
when used as permitted hereunder, will operate in all material respects as
described in the applicable Documentation, and that Services will be provided
in a professional manner consistent with industry standards.
7.3. Limitations; Remedy. Memgraph does not warrant that the Software or the
Services will be error-free, uninterrupted or meet Customer's specific
requirements or that performance of the Services will be uninterrupted.
Memgraph will have no warranty obligation under Section 7.2 for Customer's
misuse or failure to use the Software in accordance with its Documentation or
this Agreement. Customer's sole and exclusive remedy, and Memgraph's sole and
exclusive obligation, for breach of warranty will be (i) during the thirty (30)
day period following initial Delivery of the Software under an Order,
Memgraph's correction of the program errors that cause the breach of warranty,
or if Memgraph cannot substantially correct such breach in a commercially
reasonable manner, a refund of the fees paid for the nonconforming Software
(ii) during the remainder of the relevant Subscription Term, Memgraph's
delivery of Support with respect to any such program errors. In the event of a
refund remedy, Customer's licences and right to use the Software or receive
Services will end. In the event of any noticed breach of warranty with respect
to Services, Memgraph's sole and exclusive obligation shall be the
re-performance of the deficient Services.
7.4. Disclaimer. THIS SECTION 7 IS A LIMITED WARRANTY AND, EXCEPT EXPRESSLY AS
SET FORTH IN SECTION 7.2, THE SOFTWARE, INCLUDING WITHOUT LIMITATION THE
THIRD-PARTY CODE, AND ALL SERVICES ARE PROVIDED "AS IS". MEMGRAPH MAKES NO
OTHER WARRANTIES OR REPRESENTATIONS, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
AND DISCLAIMS ALL IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A
PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.
## 8. INDEMNIFICATION.
8.1. By Memgraph. Memgraph will defend against any action against Customer
brought by a third party to the extent the action is based on a claim that the
Software infringes a third party's patent, copyright or trademark (a "Claim")
and indemnify Customer from the damages, liabilities, costs and expenses
(including reasonable attorneys' fees) awarded against Customer or agreed in
settlement by Customer resulting from such Claim. If your use of the Software
is (or in Memgraph's opinion likely to be) enjoined, then Memgraph may, at its
own expense and at its option: (i) substitute substantially similar
functionality for the Software which renders it non-infringing; (ii) procure
for Customer the right to continue to use the Software; or if (i) and (ii) are
not commercially reasonable, terminate this Agreement and refund Customer any
prepaid, unused (pro-rated) Fees for the duration of the then-current
Subscription Term. The foregoing obligations of Memgraph will not apply: (i) if
the Software is modified by any party other than Memgraph, but solely to the
extent the alleged infringement is caused by such modification; (ii) if the
Software is used in combination with other products or processes not provided
or authorized by Memgraph, but solely to the extent the alleged infringement is
caused by such combination; (iii) use of any version or release of Software
other than the most current version or release made available to Customer by
Memgraph, if its use would have avoided the infringement; (iv) any unauthorized
use of the Software. THIS SECTION 8.1 SETS FORTH MEMGRAPH'S SOLE LIABILITY AND
CUSTOMER'S SOLE AND EXCLUSIVE REMEDY WITH RESPECT TO ANY CLAIM OF INTELLECTUAL
PROPERTY INFRINGEMENT.
8.2. By Customer. Customer will indemnify and hold Memgraph and its suppliers
harmless against any claims, liabilities, costs, and expenses (including
reasonable attorneys' fees) that Memgraph or its suppliers may incur as a
result of a third-party claim arising from or related to Customer Data, or
misuse or unauthorised use of the Software by Customer or any User.
8.3. Conditions. All defence and indemnity obligations under Sections 8.1 and
8.2 are conditioned on the indemnitee (i) giving the indemnitor written notice
of the relevant claim within thirty (30) days after the indemnitee receives
notice of the Claim (or sooner if required by applicable law); (ii) reasonably
cooperating with the indemnitor, at the indemnitor's expense, in the defence of
the claim; and (iii) giving the indemnitor sole control of the defence and any
settlement negotiations. The indemnitee may participate in the defence at its
expense.
## 9. LIMITATION OF LIABILITY.
9.1. TO THE EXTENT PERMITTED BY LAW, NEITHER MEMGRAPH NOR CUSTOMER SHALL BE
LIABLE TO THE OTHER OR ANY THIRD PARTY FOR LOST PROFITS (WHETHER DIRECT OR
INDIRECT) OR LOSS OF USE OR DATA, SUBSTITUTE GOODS OR SERVICES, OR FOR
INCIDENTAL, CONSEQUENTIAL, PUNITIVE, SPECIAL OR EXEMPLARY DAMAGES (INCLUDING
DAMAGE TO BUSINESS, REPUTATION OR GOODWILL), OR INDIRECT DAMAGES OF ANY TYPE
HOWEVER CAUSED, WHETHER BY BREACH OF WARRANTY, BREACH OF CONTRACT, IN TORT
(INCLUDING NEGLIGENCE) OR ANY OTHER LEGAL OR EQUITABLE CAUSE OF ACTION EVEN IF
SUCH PARTY HAS BEEN ADVISED OF SUCH DAMAGES IN ADVANCE OR IF SUCH DAMAGES WERE
FORESEEABLE.
9.2. LIMITATIONS ON DIRECT DAMAGES. EXCEPT FOR ANY EXCLUDED CLAIMS AND ANY
DAMAGES THAT CANNOT BE LIMITED UNDER APPLICABLE LAW, IN NO EVENT WILL
MEMGRAPH'S TOTAL AGGREGATE LIABILITY ARISING FROM OR RELATED TO THIS AGREEMENT,
EXCEED AN AMOUNT EQUAL TO THE TOTAL AMOUNT OF FEES PAID OR PAYABLE BY CUSTOMER
TO MEMGRAPH UNDER THIS AGREEMENT DURING THE TWELVE MONTHS PRECEDING THE CLAIM.
THE FOREGOING LIMITATIONS SHALL NOT APPLY TO: (i) PAYMENTS TO A THIRD PARTY
ARISING FROM A PARTY'S OBLIGATIONS UNDER SECTION 8 (INDEMNIFICATION); (ii)
BREACH BY A PARTY OF SECTION 10 (CONFIDENTIAL INFORMATION), AND (iii)
INFRINGEMENT BY A PARTY OF THE OTHER PARTY'S INTELLECTUAL PROPERTY RIGHTS
(COLLECTIVELY EXCLUSIONS (i)-(iii) ARE REFERRED TO AS THE "EXCLUDED CLAIMS").
WITH RESPECT TO ANY EXCLUDED CLAIMS, MEMGRAPH'S TOTAL AGGREGATE LIABILITY SHALL
IN NO EVENT EXCEED £1,000,000.
9.3. Nothing in this Agreement excludes the liability of Memgraph for death or
personal injury caused by the Supplier's negligence; or for fraud or fraudulent
misrepresentation.
## 10. CONFIDENTIALITY.
10.1. The Receiving Party will use the same degree of care that it uses to
protect the confidentiality of its own confidential information of like kind
(but not less than reasonable care) to (i) not use any confidential information
of the Disclosing Party for any purpose outside the scope of this agreement and
(ii) except as otherwise authorized by the Disclosing Party in writing, limit
access to confidential information of the Disclosing Party to those of its and
its affiliates' employees and contractors who need that access for purposes
consistent with this agreement and who have signed confidentiality agreements
with the receiving party containing protections not materially less protective
of the confidential information than those herein. Neither party will disclose
the terms of this agreement or any Orders to any third-party other than its
affiliates, legal counsel, and accountants without the other party's prior
written consent, provided that a party that makes any such disclosure to its
affiliate, legal counsel or accountants will remain responsible for such
affiliate's, legal counsel's, or accountant's compliance with this
"confidentiality" section.
10.2. Compelled Disclosure. The Receiving Party may disclose confidential
information of the Disclosing Party to the extent compelled by law to do so,
provided the Receiving Party gives the Disclosing Party prior notice of the
compelled disclosure (to the extent legally permitted) and reasonable
assistance, at the Disclosing Party's cost, if the Disclosing Party wishes to
contest the disclosure. If the receiving party is compelled by law to disclose
the Disclosing Party's confidential information as part of a civil proceeding
to which the Disclosing Party is a party, and the Disclosing Party is not
contesting the disclosure, the Disclosing Party will reimburse the Receiving
Party for its reasonable cost of complying and providing secure access to that
confidential information.
## 11. TERMINATION.
11.1. Term. The term ("Term") of this Agreement will commence on the Effective
Date and continue until all Subscriptions, licence terms and Orders expire,
unless earlier terminated in accordance with this Section 11.
11.2. Termination for Cause. In the event of a material breach of this
Agreement (excluding any breaches for which an exclusive remedy is expressly
provided), the non-breaching party may terminate this Agreement if such breach
is not cured within thirty (30) days after written notice thereof (except that
for a breach of Section 3.4 ("General Restrictions"), there will be no cure
period). For clarity, material breach of this Agreement includes, but is not
limited to, failure to timely pay amounts due hereunder, exceeding the scope of
any Licence granted hereunder (including the Licensed Capacity), violating the
Licence restrictions, breach of Section 6.1 and failing to protect the other
party's Confidential Information.
11.3. Without affecting any other right or remedy available to it, either party
may terminate this Agreement with immediate effect by giving written notice to
the other party if the other party:
11.3.1. suspends, or threatens to suspend, payment of its debts or is unable to
pay its debts as they fall due or admits inability to pay its debts or is
deemed unable to pay its debts within the meaning of section 123 of the
Insolvency Act 1986, as if the words "it is proved to the satisfaction of the
court" did not appear in sections 123(1)(e) or 123(2) of the Insolvency Act
1986; or
11.3.2. the other party commences negotiations with all or any class of its
creditors with a view to rescheduling any of its debts, or makes a proposal for
or enters into any compromise or arrangement with its creditors other than for
the sole purpose of a scheme for a solvent amalgamation of that other party
with one or more other companies or the solvent reconstruction of that other
party; or
11.3.3. a petition is filed, a notice is given, a resolution is passed, or an
order is made, for or in connection with the winding up of that other party
other than for the sole purpose of a scheme for a solvent amalgamation of that
other party with one or more other companies or the solvent reconstruction of
that other party; or
11.3.4. an application is made to court, or an order is made, for the
appointment of an administrator, or if a notice of intention to appoint an
administrator is given or if an administrator is appointed, over the other
party; or
11.3.5. the holder of a qualifying floating charge over the assets of that
other party has become entitled to appoint or has appointed an administrative
receiver; or
11.3.6. a person becomes entitled to appoint a receiver over the assets of the
other party or a receiver is appointed over the assets of the other party; or
11.3.7. a creditor or encumbrancer of the other party attaches or takes
possession of, or a distress, execution, sequestration or other such process is
levied or enforced on or sued against, the whole or any part of the other
party's assets and such attachment or process is not discharged within 30 days;
or
11.3.8. any event occurs, or proceeding is taken, with respect to the other
party in any jurisdiction to which it is subject that has an effect equivalent
or similar to any of the events mentioned in clause 11.3.1 to clause 11.3.7
(inclusive); or
11.3.9. the other party suspends or ceases, or threatens to suspend or cease,
carrying on all or a substantial part of its business.
11.4. Effect of Termination. Upon the termination of this Agreement: (i) all
licences will terminate; (ii) Customer will immediately discontinue all use of
the affected Software, erase all full and partial copies of the Software and
(subject to this Section) all other tangible embodiments of Memgraph
Confidential Information in Customer's possession or control, and promptly
certify the same to Memgraph; (iii) Memgraph may immediately cease providing
the Services; (iv) (subject to this Section), Memgraph will return or delete
all tangible embodiments of Customer Confidential Information in Memgraph's
possession or control; and (v) Sections 1 ("Definitions"), 3.4 ("General
Restrictions"), 3.5 ("Ownership; Reservation of Rights"), 5 ("Fees and
Payment"), 7.3 ("Limitations"), 7.4 ("Disclaimer"), 8 ("Indemnification"), 9
("Limitation of Liability"), 10 ("Confidentiality"), 11.4 ("Effect of
Termination"), and 12 ("Miscellaneous") will survive. If a party's file
retention policies or a valid legal order provides for backup or archival
copies of files to be retained, such party will notify the other party of such
policy or order, protect the other party's Confidential Information as required
hereunder, and permanently erase, delete, or destroy such Confidential
Information as soon as permissible under such policy or order.
## 12. MISCELLANEOUS.
12.1. Assignment. This Agreement will bind and inure to the benefit of each
party's permitted successors and assigns. Memgraph may assign this Agreement to
any affiliate or in connection with a merger, reorganization, acquisition, or
other transfer of all or substantially all of Memgraph's assets or voting
securities. Customer may not assign or transfer this Agreement, in whole or in
part, without Memgraph's written consent except that Customer may assign its
rights and obligations under this Agreement, in whole but not in part, without
Memgraph's written consent in connection with any merger, consolidation, sale
of all or substantially all of Customer's assets or voting stock, or any other
similar transaction provided that: (i) the assignee is not a direct competitor
of Memgraph; (ii) Customer provides prompt written notice of such assignment to
Memgraph; (iii) the assignee is capable of fully performing Customer's
obligations under this Agreement; and (iv) the assignee agrees to be bound by
the terms and conditions of this Agreement. Any attempt to transfer or assign
this Agreement without such written consent will be null and void.
12.2. Force Majeure. Memgraph shall have no liability to the Customer under
this Agreement if it is prevented from or delayed in performing its obligations
under this Agreement, or from carrying on its business, by acts, events,
omissions or accidents beyond its reasonable control, including strikes,
lock-outs or other industrial disputes (whether involving the workforce of
Memgraph or any other party), failure of a utility service or transport or
telecommunications network, act of God, war, pandemic, riot, civil commotion,
malicious damage, compliance with any law or governmental order, rule,
regulation or direction, accident, breakdown of plant or machinery, fire,
flood, storm or default of suppliers or subcontractors, provided that the
Customer is notified of such an event and its expected duration.
12.3. Governing Law. This Agreement and any dispute or claim arising out of or
in connection with it or its subject matter or formation (including
non-contractual disputes or claims) shall be governed by and construed in
accordance with the law of England and Wales.
12.4. Jurisdiction. Each party irrevocably agrees that the courts of England
and Wales shall have exclusive jurisdiction to settle any dispute or claim
arising out of or in connection with this Agreement or its subject matter or
formation (including non-contractual disputes or claims).
12.5. Severability; Waiver; Construction. If a court of competent jurisdiction
adjudges any provision of this Agreement to be invalid or unenforceable, the
remaining provisions of this Agreement, if capable of substantial performance,
will continue in full force and effect without being impaired or invalidated in
any way. The parties agree to replace any invalid provision with a valid
provision that most closely approximates the intent and economic effect of the
invalid provision. All waivers must be in writing. A party's consent to, or
waiver of, enforcement of this Agreement on one occasion will not be deemed a
waiver of any other provision or such provision on any other occasion. In this
Agreement, the word "including" means "including but not limited to." No
presumption will operate in favour of or against any party as a result of its
role in drafting this Agreement.
12.6. Subcontractors. Memgraph may use the services of subcontractors in
connection with its performance of this Agreement, provided that Memgraph
remains solely responsible for (i) compliance of any such subcontractor with
the terms of this Agreement and (ii) the overall performance of Memgraph as
required under this Agreement.
12.7. Use of Aggregate Data. Customer agrees that Memgraph may collect, use and
disclose quantitative data and metadata derived from the use of the Software
(i) for its own internal, statistical analysis, (ii) to develop and improve the
Software and (iii) to create and distribute reports and other materials
regarding use of the Software. For clarity, any such data collected, used, and
disclosed will be in anonymized aggregate form only and shall not identify
Customer or its Users, or disclose any Customer Data.
12.8. Independent Contractors. The parties are independent contractors. No
agency, partnership, franchise, joint venture, or employment relationship is
intended or created by this Agreement. Neither party has the power or authority
to create or assume any obligation, or make any representations or warranties,
on behalf of the other party.
12.9. Publicity. Memgraph may, in conformity with Customer's trademark usage
guidelines, use Customer's name and logo in Memgraph's sales and marketing
materials, including in business presentations, Customer lists, and on
websites. Neither party will issue a press release regarding this Agreement
without the other party's prior written consent. Neither party will disclose
the terms of this Agreement to any third party, except as required by law.
12.10. Notice. Any notice, consent, or waiver hereunder must be in writing,
addressed to the attention of "Legal Department" at the address set forth
above, and delivered by personal delivery, reputable rapid courier, or
certified/registered mail, return receipt requested, and will be deemed given
upon personal delivery, one (1) day after deposit with an overnight domestic
courier, two (2) days after deposit with an international courier, or five (5)
days after deposit in the certified or registered mail. A party may specify a
new address by providing notice to the other party in accordance with this
Section.
12.11. Compliance with Law. Each party will comply with all applicable laws,
regulations, and orders of any governmental authority of competent jurisdiction
in its performance under this Agreement, including but not limited to those
applicable to data collection and the privacy and security of personal
information, including trans-border data transfers and data breach notification
requirements as required of each party by law.
12.12. Supremacy; Modification. This Agreement will prevail over any written
instrument submitted by Customer; the terms of any purchase order,
acknowledgement, or similar document submitted by Customer to Memgraph will
have no effect. If the express terms of an Order Document conflict with this
Agreement, the terms on the Order Document will prevail, but only with respect
to that Order Document. This Agreement cannot be varied or supplemented by
course of dealing or by usage of trade. All modifications or amendments to this
Agreement must be in writing and signed by both parties, except that subsequent
renewals and purchases of additional Licensed Capacity can be procured by
payment against an issued invoice as set forth in Section 5 ("Fees and
payment") above.
12.13. No Third Party Beneficiaries. This Agreement is not intended and shall
not be construed to give any third party any interest or rights with respect to
or in connection with any agreement or provision herein, except as expressly
provided for in this Agreement.
12.14. Entire Agreement. This Agreement in its original English text, sets
forth the complete, exclusive, and final agreement of the parties concerning
the subject matter hereof, supersedes, replaces, and merges all prior and
contemporaneous agreements, communications, and understandings, both written
and oral, between them concerning the subject matter hereof. This Agreement may
be executed in counterparts.
