-# Change Log
+Change Log for all versions of Memgraph can be found on-line at
+https://docs.memgraph.com/memgraph/changelog
 
-## Future
-
-### Breaking Changes
-
-* Changed `MEMORY LIMIT num (KB|MB)` clause in the procedure calls to `PROCEDURE MEMORY LIMIT num (KB|MB)`.
-  The functionality is still the same.
-
-### Major Feature and Improvements
-
-* Added replication to community version.
-* Add support for multiple query modules directories at the same time.
-  You can now define multiple, comma-separated paths to directories from
-  which the modules will be loaded using the `--query-modules-directory` flag.
-* Added support for programatically reading in data from CSV files through the
-  `LOAD CSV` clause. We support CSV files with and without a header, the
-  supported dialect being Excel.
-* Added a new flag `--memory-limit` which enables the user to set the maximum total amount of memory
-  memgraph can allocate during its runtime.
-* Added `FREE MEMORY` query which tries to free unusued memory chunks in different parts of storage.
-* Added the memory limit and amount of currently allocated bytes in the result of `SHOW STORAGE INFO` query.
-* Added `QUERY MEMORY LIMIT num (KB|MB)` to Cypher queries which allows you to limit memory allocation for
-  the entire query. It can be added only at the end of the entire Cypher query.
-
-### Bug Fixes
-
-* Fixed garbage collector by correctly marking the oldest current timestamp
-  after the database was recovered using the durability files.
-* Fixed reloading of the modules with changed result names.
-
-## v1.3.0
-
-### Breaking Changes
-
-* Added extra information in durability files to support replication, making it
-  incompatible with the durability files generated by older versions of
-  Memgraph. Even though the replication is an Enterprise feature, the files are
-  compatible with the Community version.
-
-### Major Features and Improvements
-
-* Added support for data replication across a cluster of Memgraph instances.
-  Supported instance types are MAIN and REPLICA. Supported replication modes
-  are SYNC (all SYNC REPLICAS have to receive data before the MAIN can commit
-  the transaction), ASYNC (MAIN doesn't care if data is replicated), SYNC WITH
-  TIMEOUT (MAIN will wait for REPLICAS within the given timeout period, after
-  timout, replication isn't aborted but the replication demotes the REPLICA to
-  the ASYNC mode).
-* Added support for query type deduction. Possible query types are `r` (read),
-  `w` (write), `rw` (read-write). The query type is returned as a part of the
-  summary.
-* Improved logging capabilities by introducing granular logging levels. Added
-  new flag, `--log-level`, which specifies the minimum log level that will be
-  printed. E.g., it's possible to print incoming queries or Bolt server states.
-* Added ability to lock the storage data directory by executing the `LOCK DATA
-  DIRECTORY;` query which delays the deletion of the files contained in the
-  data directory. The data directory can be unlocked again by executing the
-  `UNLOCK DATA DIRECTORY;` query.
-
-### Bug Fixes and Other Changes
-
-* Added cleanup of query executions if not in an explicit transaction.
-* Fix RPC dangling reference.
-
-## v1.2.0
-
-### Breaking Changes
-
-* SSL is disabled by default (`--bolt-cert-file` and `--bolt-key-file` are
-  empty). This change might only affect the client connection configuration.
-
-### Major Features and Improvements
-
-* Added support for Bolt v4.0 and v4.1.
-* Added `mgp_networkx.py` as an alternative implementation of NetworkX graph
-  objects, which is useful to use Memgraph data from NetworkX algorithms
-  optimally.
-* Added `nxalg.py` query module as a proxy to NetworkX algorithms.
-* Added plan optimization to use a label-property index where the property is
-  not null. As a result, the query engine, instead of scanning all elements and
-  applying the filter, performs a label-property index lookup when possible.
-
-### Bug Fixes and Other Changes
-
-* Fixed Cypher `ID` function `Null` handling. When the `ID` function receives
-  `Null`, it will also return `Null`.
-* Fixed bug that caused random crashes in SSL communication on platforms
-  that use older versions of OpenSSL (< 1.1) by adding proper multi-threading
-  handling.
-* Fix `DISCARD` message handling. The query is now executed before discarding
-  the results.
-
-## v1.1.0
-
-### Major Features and Improvements
-
-* Properties in nodes and edges are now stored encoded and compressed. This
-  change significantly reduces memory usage. Depending on the specific dataset,
-  total memory usage can be reduced up to 50%.
-* Added support for rescanning query modules. Previously, the query modules
-  directory was scanned only upon startup. Now it is scanned each time the user
-  requests to load a query module. The functions used to load the query modules
-  were renamed to `mg.load()` and `mg.load_all()` (from `mg.reload()` and
-  `mg.reload_all()`).
-* Improved execution performance of queries that have an IN list filter by
-  using label+property indices.
-  Example: `MATCH (n:Label) WHERE n.property IN [] ...`
-* Added support for `ANY` and `NONE` openCypher functions. Previously, only
-  `ALL` and `SINGLE` functions were implemented.
-
-### Bug Fixes and Other Changes
-
-* Fixed invalid paths returned by variable expansion when the starting node and
-  destination node used the same symbol.
-  Example: `MATCH path = (n:Person {name: "John"})-[:KNOWS*]->(n) RETURN path`
-* Improved semantics of `ALL` and `SINGLE` functions to be consistent with
-  openCypher when handling lists with `Null`s.
-* `SHOW CONSTRAINT INFO` now returns property names as a list for unique
-  constraints.
-* Escaped label/property/edgetype names in `DUMP DATABASE` to support names
-  with spaces in them.
-* Fixed handling of `DUMP DATABASE` queries in multi-command transactions
-  (`BEGIN`, ..., `COMMIT`).
-* Fixed handling of various query types in explicit transactions. For example,
-  constraints were allowed to be created in multi-command transactions
-  (`BEGIN`, ..., `COMMIT`) but that isn't a transactional operation and as such
-  can't be allowed in multi-command transactions.
-* Fixed integer overflow bugs in `COUNT`, `LIMIT` and `SKIP`.
-* Fixed integer overflow bugs in weighted shortest path expansions.
-* Fixed various other integer overflow bugs in query execution.
-* Added Marvel Comic Universe tutorial.
-* Added FootballTransfers tutorial.

-  relative paths.
-* Added support for Python query modules. This release of Memgraph supports
-  query modules written using the already existing C API and the new Python
-  API.

-  is compatible with the Neo4j batch CSV importer.
-* Snapshot and write-ahead log format changed (backward compatible with v0.50).
-* Vertices looked up by their openCypher ID (`MATCH (n) WHERE ID(n) = ...`)
-  will now find the node in O(logn) instead of O(n).
-* Improved planning of BFS expansion, a faster, specific approach is now
-  favored instead of a ScanAll+Filter operation.

+# 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.

+# 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.

-## 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.

+#   * Direct download from the "source of truth" is slower and unreliable because of the whole internet in-between
+#   * When a new dependency has to be added, both urls could be the same, later someone could optimize if required
+
+# The goal of having primary urls is to have links to the "local" cache of
+# dependencies where these dependencies could be downloaded as fast as
+# possible. The actual cache server could be on your local machine, on a
+# dedicated machine inside the build cluster or on the actual build machine.

+      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

+      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

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          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,

+         (“Receiving Party”), whether orally or in writing, that is designated as confidential or that reasonably should
+         be understood to be confidential given the nature of the information and the circumstances of disclosure.
+         Customer’s Confidential Information includes Customer Data; Memgraph Confidential Information includes the
+         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

+         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
+         independently developed by the Receiving Party.

+         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.

+         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.
+   1.8.  “Services” means those services, including Support Services, which may be provided to Customer by Memgraph
+         pursuant to the terms of this Agreement and are expressly limited to those services directly related to

+   1.9. “Software” means Memgraph’s proprietary downloadable graph database enterprise software known as Memgraph
+         Enterprise Edition (MEE) (“Enterprise Software”) and the associated technical documentation located at
+         https://docs.memgraph.com/ (“Documentation”), as well as software updates, upgrades, bug fixes, or modified
+         versions thereof that Memgraph licenses or provides to Customer directly or indirectly throughout the Subscription
+         Term. For the avoidance of doubt, for the purpose of this Agreement, the term Software excludes Memgraph’s
+         free-to-use software known as Memgraph Community Edition (MCE) which is licensed pursuant to separate terms
+         (including the Business Source Licence (BSL) or Apache 2.0) as indicated here: https://memgraph.com/legal.
+   1.10. “Subscription Term” means the fixed term, of not less than one (1) year, designated in an Order Document

+         Subscription Term as set forth in an Order Document.
+   1.11. “Support” means the support and maintenance services, including any updates, upgrades, patches, enhancements
+         and bug fixes for the Software that may be provided to Customer by Memgraph pursuant to the terms of this
+         Agreement.
+   1.12. “Users” means employees and Contractors of Customer that Customer has permitted or authorized to access and use
+         of the Software on Customer’s behalf pursuant to the terms of this Agreement.
+
+2. ORDERS, DELIVERY; SUPPORT.
+   2.1.  Delivery. Customer shall access the Software from Memgraph’s website or online repository (as instructed by
+         Memgraph) after the Effective Date. Memgraph shall deliver to Customer the licence key necessary to unlock the
+         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.

+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      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
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable

+      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

+      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
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          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.
+
+                     END OF TERMS AND CONDITIONS

+
+      "Source" form shall mean the preferred form for making modifications,

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      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
+      this License, each Contributor hereby grants to You a perpetual,
+      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
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed

+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.

-## 3. LICENCE GRANTS; RESTRICTIONS AND PROPRIETARY RIGHTS.

-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

-Term, to install, and use the Enterprise Software up to the maximum capacity

-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

-the Software from its computer systems. Memgraph has the right to terminate a
-Trial Licence at any time for any reason.

-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

-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'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)

-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

-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.
-

-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)

-
-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.

-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

-other party with one or more other companies or the solvent reconstruction of
-that other party; or

-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

-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,

-
-12.5. Severability; Waiver; Construction. If a court of competent jurisdiction
-adjudges any provision of this Agreement to be invalid or unenforceable, the

-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

-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

-
-12.8. Independent Contractors. The parties are independent contractors. No
-agency, partnership, franchise, joint venture, or employment relationship is

-to create or assume any obligation, or make any representations or warranties,
-on behalf of the other party.

-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.
