PLEASE READ CAREFULLY THIS TIMESCALE LICENSE AGREEMENT ("TSL Agreement"), WHICH
CONSTITUTES A LEGALLY BINDING AGREEMENT AND GOVERNS USE OF THE TIMESCALE
TIME-SERIES DATABASE SOFTWARE AND RELATED SOFTWARE THAT IS PROVIDED SUBJECT TO
THIS TSL AGREEMENT.  BY INSTALLING OR USING SUCH SOFTWARE, YOU AGREE THAT YOU
HAVE READ AND AGREE TO BE BOUND BY THE TERMS AND CONDITIONS OF THIS TSL
AGREEMENT.  IF YOU DO NOT AGREE WITH SUCH TERMS AND CONDITIONS, YOU MAY NOT
INSTALL OR USE SUCH SOFTWARE.  IF YOU ARE INSTALLING OR USING SUCH SOFTWARE ON
BEHALF OF A LEGAL ENTITY, YOU REPRESENT AND WARRANT THAT YOU HAVE THE AUTHORITY

This TSL Agreement is entered into by and between Timescale, Inc. ("Timescale")
and you or the legal entity on whose behalf you are accepting this TSL
Agreement ("You").

0. BACKGROUND

   The Timescale time-series database software and related software is offered
   as "open code" or "source-available" code.  This means that all source code
   of the software is available for inspection and download at
   https://github.com/timescale.  The Timescale software is composed of two
   major pieces.

   The first piece (referred to herein as the Timescale Open Source Software,
   as defined below) is open source software that is licensed under the Apache
   Version 2.0 license.

   The second piece (referred to herein as the TSL Licensed Software, as
   defined below) is all of the Timescale Software other than the Timescale
   Open Source Software. The TSL Licensed Software may be used under this TSL
   Agreement without charge.

1. GOVERNING LICENSES

   1.1 Source Code.  The source code for all Timescale Software is made
   publicly available by Timescale at https://github.com/timescale.  However,
   different license agreements govern the use of different parts of the
   Timescale Software source code.  The use of Timescale Open Source Software,
   in both source and executable forms, is governed by the terms of the Apache
   License Version 2.0, a copy of which is available at
   https://opensource.org/licenses/Apache-2.0.  The use of all other Timescale
   Software, in both source and executable forms, is governed by this TSL
   Agreement.

   1.2 License Rights to Your Customers.  As set forth in Section 2.1 below,
   the use by Your customers of the Timescale Software as part of any Value
   Added Products or Services that You distribute will be subject to the most
   current version of this TSL Agreement.

2. GRANT OF LICENSES

   2.1 Grant.  Conditioned upon compliance with all of the terms and conditions
   of this TSL Agreement, Timescale grants to You at no charge the following
   limited, non-exclusive, non-transferable, fully paid up, worldwide licenses,
   without the right to grant or authorize sublicenses (except as set forth in
   Section 2.3):

      (a) Internal Use.  A license to copy, compile, install, and use the
      Timescale Software and Derivative Works solely for Your own internal
      business purposes in a manner that does not expose or give access to,

      Definition Interfaces or the Timescale Data Manipulation Interfaces to
      any person or entity other than You or Your employees and Contractors
      working on Your behalf.

      (b) Value Added Products or Services.  A license (i) to copy, compile,

      Your customers) copies of the Timescale Software binaries or of
      Derivative Works solely in binary form, and both solely as incorporated

      that (1) You notify Your customers that use of such Timescale Software
      or Derivative Works is subject to this TSL Agreement and You provide to

      Agreement or a URL from which the most current version of this TSL
      Agreement may be obtained, and (2) the customer is prohibited, either
      contractually or technically, from defining, redefining, or modifying

      Timescale Database utilized by such Value Added Products or Services.

      (c) Distribution of Source Code or Binaries in Standalone Form.  Subject
      to the prohibitions in Section 2.2 below, a license to copy and
      distribute the Timescale Software source code and binaries solely in
      unmodified standalone form and subject to the terms and conditions of
      the most current version of this TSL Agreement.

      (d) Derivative Works.  A license (i) to prepare, compile, and test

   Affiliates to exercise the licenses set forth in Section 2.1, provided that
   such exercise by Contractors must be solely for your benefit and/or the
   benefit of Your Affiliates, and You shall be responsible for all acts and
   omissions of such Contractors and Affiliates in connection with such
   exercise of the licenses, including but not limited to breach of any terms
   of this TSL Agreement.

   2.4 Reservation of Rights.  Except as expressly set forth in Section 2.1, no

7. GENERAL

   7.1 Complete Agreement.  This TSL Agreement completely and exclusively
   states the entire agreement of the parties regarding the subject matter
   hereof and supersedes all prior proposals, agreements, or other
   communications between the parties, oral or written, regarding such subject
   matter.

   7.2 Modification.  This TSL Agreement may be modified by Timescale from time
   to time, and any such modifications will be effective upon the "Posted Date"
   set forth at the top of the modified agreement. The modified agreement shall
   govern any new version of the TSL Licensed Software (and all its constituent
   source code and binaries) that is officially released as a complete version
   release by Timescale on or after such Posted Date. Except as set forth in
   this Section 7.2, this TSL Agreement may not be amended except by a writing
   executed by both parties.

   7.3 Governing Law.  This TSL Agreement shall be governed by and construed
   solely under the laws of the State of New York, without application of any
   choice of law rules or principles that would lead to the applicability of
   the law of any other jurisdiction.  None of the provisions of either the
   United Nations Convention on Contracts for the International Sale of Goods
   or the Uniform Computer Information Transactions Act shall apply.

   7.4 Unenforceability.  If any provision of this TSL Agreement is held
   unenforceable, the remaining provisions of this TSL Agreement shall remain
   in effect and the unenforceable provision shall be replaced by an
   enforceable provision that best reflects the original intent of the parties.

   7.5 Injunctive Relief.  You acknowledge that a breach or threatened breach
   of any provision of this TSL Agreement will cause irreparable harm to
   Timescale for which damages at law will not provide adequate relief, and
   Timescale shall therefore be entitled to injunctive relief against such
   breach or threatened breach without being required to post a bond.

   7.6 Assignment.  You may not assign this TSL Agreement, including by
   operation of law in connection with a merger or acquisition or otherwise,
   in whole or in part, without the prior written consent of Timescale, which
   Timescale may grant or withhold in its sole and absolute discretion.  Any
   assignment in violation of the preceding sentence is void.

   7.7 Independent Contractors.  The parties to this TSL Agreement are
   independent contractors and this TSL Agreement does not establish any
   relationship of partnership, joint venture, employment, franchise, or agency
   between the parties.

   7.8 U.S. Government Rights.  The Timescale Software and related
   documentation are "Commercial Items", as that term is defined at 48
   C.F.R. §2.101, consisting of "Commercial Computer Software" and "Commercial
   Computer Software Documentation," as such terms are used in 48
   C.F.R. §12.212 or 48 C.F.R. §227.7202, as applicable, and
   are being licensed to U.S. Government end users (a) only as
   Commercial Items and (b) with only those rights as are granted to all other
   end users pursuant to the terms and conditions of this TSL Agreement.
