  2. Licenses.

    (a) License to Dgraph Core.  The License for Dgraph
        Core is the Apache License, Version 2.0 ("Apache License").
        The Apache License includes a grant of patent license, as well as
        redistribution rights that are contingent on several requirements.
        Please see

            http://www.apache.org/licenses/LICENSE-2.0

        for full terms.  Dgraph Core is a no-cost, entry-level license and as
        such, contains the following disclaimers: NOTWITHSTANDING ANYTHING TO
        THE CONTRARY HEREIN, DGRAPH CORE IS PROVIDED "AS IS" AND "AS
        AVAILABLE", AND ALL EXPRESS OR IMPLIED WARRANTIES ARE EXCLUDED AND
        DISCLAIMED, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF
        MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT,
        AND ANY WARRANTIES ARISING BY STATUTE OR OTHERWISE IN LAW OR FROM
        COURSE OF DEALING, COURSE OF PERFORMANCE, OR USE IN TRADE.  For
        clarity, the terms of this Agreement, other than the relevant
        definitions in Section 1 and this Section 2(a) do not apply to Dgraph
        Core.

    (b) License to Dgraph Enterprise Edition.

      i   Grant of Copyright License: Subject to the terms of this Agreement,
          Licensor hereby grants to You a worldwide, non-exclusive,
          non-transferable limited license to reproduce, prepare Enterprise
          Derivative Works (as defined below) of, publicly display, publicly
          perform, sublicense, and distribute Dgraph Enterprise Edition
          for Your business purposes, for so long as You are not in violation
          of this Section 2(b) and are current on all payments required by
          Section 4 below.

      ii  Grant of Patent License: Subject to the terms of this Agreement,
          Licensor hereby grants to You a worldwide, non-exclusive,
          non-transferable limited patent license to make, have made, use,
          offer to sell, sell, import, and otherwise transfer Dgraph
          Enterprise Edition, where such license applies only to those patent
          claims licensable by Licensor 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.

      iii License to Third Party Works:  From time to time Dgraph Labs may
          use, or provide You access to, Third Party Works in connection
          Dgraph Enterprise Edition.  You acknowledge and agree that in
          addition to this Agreement, Your use of Third Party Works is subject
          to all other terms and conditions set forth in the License provided
          with or contained in such Third Party Works.  Some Third Party Works
          may be licensed to You solely for use with Dgraph Enterprise
          Edition under the terms of a third party License, or as otherwise
          notified by Dgraph Labs, and not under the terms of this
          Agreement.  You agree that the owners and third party licensors of
          Third Party Works are intended third party beneficiaries to this
          Agreement.

  3. Support.  From time to time, in its sole discretion, Dgraph Labs may
     offer professional services or support for Dgraph, which may now or in
     the future be subject to additional fees.

  4. Fees for Dgraph Enterprise Edition or Dgraph Support.

    (a) Fees.  The License to Dgraph Enterprise Edition is conditioned upon
        Your payment of the fees which You agree to pay to Dgraph Labs in
        accordance with the payment terms agreed upon by contacting
        contact@dgraph.io.  Any professional services or support for Dgraph
        may also be subject to Your payment of fees, which will be
        specified by Dgraph Labs when you sign up to receive such
        professional services or support.  Dgraph Labs reserves the right
        to change the fees at any time with prior written notice; for
        recurring fees, any such adjustments will take effect as of the
        next pay period.

    (b) Overdue Payments and Taxes. Overdue payments are subject to a service
        charge equal to the lesser of 1.5% per month or the maximum legal
        interest rate allowed by law, and You shall pay all Dgraph Labs’
        reasonable costs of collection, including court costs and attorneys’
        fees.  Fees are stated and payable in U.S. dollars and are exclusive of
        all sales, use, value added and similar taxes, duties, withholdings and
        other governmental assessments (but excluding taxes based on Dgraph
        Labs’ income) that may be levied on the transactions contemplated by
        this Agreement in any jurisdiction, all of which are Your responsibility
        unless you have provided Dgraph Labs with a valid tax-exempt
        certificate.

    (c) Record-keeping and Audit.  If fees for Dgraph Enterprise Edition
        are based on the number of cores or servers running on Dgraph
        Enterprise Edition or another use-based unit of measurement, You must
        maintain complete and accurate records with respect to Your use of
        Dgraph Enterprise Edition and will provide such records to
        Dgraph Labs for inspection or audit upon Dgraph Labs’ reasonable
        request.  If an inspection or audit uncovers additional usage by You for
        which fees are owed under this Agreement, then You shall pay for such
        additional usage at Dgraph Labs’ then-current rates.

  5. Trial License.  If You have signed up for a trial or evaluation of
     Dgraph Enterprise Edition, Your License to Dgraph Enterprise
     Edition is granted without charge for the trial or evaluation period
     specified when You signed up, or if no term was specified, for thirty (30)
     calendar days, provided that Your License is granted solely for purposes of
     Your internal evaluation of Dgraph Enterprise Edition during the trial
     or evaluation period (a "Trial License").  You may not use Dgraph
     Enterprise Edition under a Trial License more than once in any twelve (12)
     month period.  Dgraph Labs may revoke a Trial License at any time and
     for any reason.  Sections 3, 4, 9 and 11 of this Agreement do not apply to
     Trial Licenses.

  6. 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.

    (e) Enterprise Derivative Works: Derivative Works of Dgraph Enterprise
        Edition ("Enterprise Derivative Works") may be made, reproduced and
        distributed in any medium, with or without modifications, in Source or
        Object form, provided that each Enterprise Derivative Work will be
        considered to include a License to Dgraph Enterprise Edition and
        thus will be subject to the payment of fees to Dgraph Labs by any
        user of the Enterprise Derivative Work.

  7. Submission of Contributions. Unless You explicitly state otherwise, any
     Contribution intentionally submitted for inclusion in Dgraph by You to
     Dgraph Labs shall be under the terms and conditions of

         https://cla-assistant.io/dgraph-io/dgraph

     (which is based off of the Apache License), without any additional terms or
     conditions, payments of royalties or otherwise to Your benefit.
     Notwithstanding the above, nothing herein shall supersede or modify the
     terms of any separate license agreement You may have executed with
     Dgraph Labs regarding such Contributions.

  8. Trademarks.  This License does not grant permission to use the trade names,
     trademarks, service marks, or product names of Licensor, except as required
     for reasonable and customary use in describing the origin of the Work and
     reproducing the content of the NOTICE file.

  9. Limited Warranty.

    (a) Warranties.  Dgraph Labs warrants to You that: (i) Dgraph
        Enterprise Edition will materially perform in accordance with the
        applicable documentation for ninety (90) days after initial delivery to
        You; and (ii) any professional services performed by Dgraph Labs
        under this Agreement will be performed in a workmanlike manner, in
        accordance with general industry standards.

    (b) Exclusions.  Dgraph Labs’ warranties in this Section 9 do not extend
        to problems that result from: (i) Your failure to implement updates
        issued by Dgraph Labs during the warranty period; (ii) any
        alterations or additions (including Enterprise Derivative Works and
        Contributions) to Dgraph not performed by or at the direction of
        Dgraph Labs; (iii) failures that are not reproducible by Dgraph
        Labs; (iv) operation of Dgraph Enterprise Edition in violation of
        this Agreement or not in accordance with its documentation; (v) failures
        caused by software, hardware or products not licensed or provided by
        Dgraph Labs hereunder; or (vi) Third Party Works.

    (c) Remedies.  In the event of a breach of a warranty under this Section 9,
        Dgraph Labs will, at its discretion and cost, either repair, replace
        or re-perform the applicable Works or services or refund a portion of
        fees previously paid to Dgraph Labs that are associated with the
        defective Works or services. This is Your exclusive remedy, and
        Dgraph Labs’ sole liability, arising in connection with the limited
        warranties herein.

  10. Disclaimer of Warranty.  Except as set out in Section 9, unless required
      by applicable law, 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, arising out of course
      of dealing, course of performance, or usage in trade, including, without
      limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT,
      MERCHANTABILITY, CORRECTNESS, RELIABILITY, or FITNESS FOR A PARTICULAR
      PURPOSE, all of which are hereby disclaimed.  You are solely responsible
      for determining the appropriateness of using or redistributing Works and
      assume any risks associated with Your exercise of permissions under the
      applicable License for such Works.

  11. Limited Indemnity.

    (a) Indemnity.  Dgraph Labs will defend, indemnify and hold You harmless
        against any third party claims, liabilities or expenses incurred
        (including reasonable attorneys’ fees), as well as amounts finally
        awarded in a settlement or a non-appealable judgement by a court
        ("Losses"), to the extent arising from any claim or allegation by a
        third party that Dgraph Enterprise Edition infringes or
        misappropriates a valid United States patent, copyright or trade secret
        right of a third party; provided that You give Dgraph Labs: (i)
        prompt written notice of any such claim or allegation; (ii) sole control
        of the defense and settlement thereof; and (iii) reasonable cooperation
        and assistance in such defense or settlement.  If any Work within
        Dgraph Enterprise Edition becomes or, in Dgraph Labs’ opinion,
        is likely to become, the subject of an injunction, Dgraph Labs may,
        at its option, (A) procure for You the right to continue using such
        Work, (B) replace or modify such Work so that it becomes non-infringing
        without substantially compromising its functionality, or, if (A) and (B)
        are not commercially practicable, then (C) terminate Your license to the
        allegedly infringing Work and refund to You a prorated portion of the
        prepaid and unearned fees for such infringing Work.  The foregoing
        states the entire liability of Dgraph Labs with respect to
        infringement of patents, copyrights, trade secrets or other intellectual
        property rights.

    (b) Exclusions.  The foregoing obligations shall not apply to: (i) Works
        modified by any party other than Dgraph Labs (including Enterprise
        Derivative Works and Contributions), if the alleged infringement relates
        to such modification, (ii) Works combined or bundled with any products,
        processes or materials not provided by Dgraph Labs where the alleged
        infringement relates to such combination, (iii) use of a version of
        Dgraph Enterprise Edition other than the version that was current
        at the time of such use, as long as a non-infringing version had been
        released, (iv) any Works created to Your specifications, (v)
        infringement or misappropriation of any proprietary right in which You
        have an interest, or (vi) Third Party Works.  You will defend, indemnify
        and hold Dgraph Labs harmless against any Losses arising from any
        such claim or allegation, subject to conditions reciprocal to those in
        Section 11(a).

  12. Limitation of Liability.  In no event and under no legal or equitable
      theory, whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts), and notwithstanding anything in this Agreement to the
      contrary, shall Licensor or any Contributor be liable to You for (i) any
      amounts in excess, in the aggregate, of the fees paid by You to Dgraph
      Labs under this Agreement in the twelve (12) months preceding the date the
      first cause of liability arose), or (ii) any indirect, special,
      incidental, punitive, exemplary, reliance, or consequential damages of any
      character arising as a result of this Agreement or out of the use or
      inability to use the Work (including but not limited to damages for loss
      of goodwill, profits, data or data use, work stoppage, computer failure or
      malfunction, cost of procurement of substitute goods, technology or
      services, or any and all other commercial damages or losses), even if such
      Licensor or Contributor has been advised of the possibility of such
      damages. THESE LIMITATIONS SHALL APPLY NOTWITHSTANDING THE FAILURE OF THE
      ESSENTIAL PURPOSE OF ANY LIMITED REMEDY.

  13. Accepting Warranty or Additional Liability.  While redistributing Works or
      Derivative Works thereof, and without limiting your obligations under
      Section 6, 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 Dgraph Labs and each other Contributor harmless for
      any liability incurred by, or claims asserted against, such Contributor by
      reason of your accepting any such warranty or additional liability.

  14. General.

    (a) Relationship of Parties.  You and Dgraph Labs are independent
        contractors, and nothing herein shall be deemed to constitute either
        party as the agent or representative of the other or both parties as
        joint venturers or partners for any purpose.

    (b) Export Control.  You shall comply with the U.S. Foreign Corrupt
        Practices Act and all applicable export laws, restrictions and
        regulations of the U.S. Department of Commerce, and any other applicable
        U.S. and foreign authority.

    (c) Assignment.  This Agreement and the rights and obligations herein may
        not be assigned or transferred, in whole or in part, by You without the
        prior written consent of Dgraph Labs.  Any assignment in violation of
        this provision is void.  This Agreement shall be binding upon, and inure
        to the benefit of, the successors and permitted assigns of the parties.

    (d) Governing Law.  This Agreement shall be governed by and construed under
        the laws of the State of New York and the United States without regard
        to conflicts of laws provisions thereof, and without regard to the
        Uniform Computer Information Transactions Act.

    (e) Attorneys’ Fees.  In any action or proceeding to enforce rights under
        this Agreement, the prevailing party shall be entitled to recover its
        costs, expenses and attorneys’ fees.

    (f) Severability.  If any provision of this Agreement is held to be invalid,
        illegal or unenforceable in any respect, that provision shall be limited
        or eliminated to the minimum extent necessary so that this Agreement
        otherwise remains in full force and effect and enforceable.

    (g) Entire Agreement; Waivers; Modification.  This Agreement constitutes the
        entire agreement between the parties relating to the subject matter
        hereof and supersedes all proposals, understandings, or discussions,
        whether written or oral, relating to the subject matter of this
        Agreement and all past dealing or industry custom. The failure of either
        party to enforce its rights under this Agreement at any time for any
        period shall not be construed as a waiver of such rights. No changes,
        modifications or waivers to this Agreement will be effective unless in
        writing and signed by both parties.
