block (“You” and “Your”) and DayZero Software, Inc. d/b/a Superblocks, (“Superblocks”), effective as of
the date of you accept this CLA (as set forth herein) and sets forth the terms pursuant to which You provides
Contributions to Superblocks. BY MAKING OR SUBMITTING ANY CONTRIBUTION TO
SUPERBLOCKS, YOU ACKNOWLEDGE AND AGREE THAT YOU ARE BOUND BY THE TERMS OF
THIS CLA AND THAT SUPERBLOCKS MAY CHOOSE TO USE YOUR CONTRIBUTION UNDER
THE TERMS SET FORTH HEREIN.

You accept and agree to the following terms and conditions for Your present and future Contributions
submitted to Superblocks. In return, Superblocks will not use Your Contributions in a way that is contrary to
Superblocks’s business objectives. Except for the license granted herein to Superblocks and recipients of
software distributed by Superblocks, You reserve all right, title, and interest in and to Your Contributions.

1. Definitions. “Contribution” means any original work of authorship, including any modifications or
additions to an existing work, that You intentionally submit to Superblocks for inclusion in, or documentation
of, any of the products owned or managed by Superblocks (the “Work”). “Submit” means any form of
electronic, verbal, or written communication sent to Superblocks 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, Superblocks for the purpose of discussing and improving the Work, but
excluding communication that is conspicuously marked or otherwise designated in writing by You as “Not a
Contribution.”

2. Copyright License. Subject to the terms and conditions of this CLA, You hereby grant to Superblocks
and to recipients of software distributed by Superblocks 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 Your Contributions and such derivative works.

3. Patent License. Subject to the terms and conditions of this CLA, You hereby grant to Superblocks and
to recipients of software distributed by Superblocks 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 You that are necessarily infringed by Your Contribution(s) alone or by combination of Your
Contribution(s) with the Work to which such Contribution(s) was submitted. If any entity institutes patent
litigation against You or any other entity (including a cross-claim or counterclaim in a lawsuit) alleging that
Your Contribution, or the Work to which You have contributed, constitutes direct or contributory patent
infringement, then any patent licenses granted to that entity under this CLA for that Contribution or Work will
terminate as of the date such litigation is filed.

4. Representations and Warranties. You represent and warrant to Superblocks that:

  a. You are legally entitled to grant the above license, and if Your employer(s) has rights to
  intellectual property that You create that includes Your Contributions, then You represent and warrant that
  You have received permission to make Contributions on behalf of that employer, that Your employer has
  waived such rights for Your Contributions to Superblocks, or that Your employer has executed a separate
  CLA with Superblocks;

  b. Each of Your Contributions is Your original creation (see section 6 for submissions on behalf

  of others); and

  c. Your Contribution submissions include complete details of any third-party license or other
  restriction (including, but not limited to, related patents and trademarks) of which You are personally aware
  and which are associated with any part of Your Contributions.

5. Support; Disclaimer. You are not expected to provide support for Your Contributions, except to the
extent You desire to do so. You may provide support for free, for a fee, or not at all. Unless required by
applicable law or agreed to in writing, You provide Your 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.

submit it to Superblocks separately from any Contribution, identifying the complete details of its source and
of any license or other restriction (including, but not limited to, related patents, trademarks, and license
agreements) of which You are personally aware, and conspicuously marking the work as “Submitted on
behalf of a third-party: [named here]”.

7. Inaccuracies. You agree to notify Superblocks of any facts or circumstances of which You become
aware that would make Your representations in this CLA inaccurate in any respect.

hereof, and supersedes any and all prior or contemporaneous representations, understandings, and agreements,
between the parties regarding same. If any part of this CLA is found to be unenforceable, the remaining
