6.3.
Further Assurances. All parties agree that, from time to time, each of them will take such other action and to execute,

6.4.
Specific Performance. The parties agree that the covenants and obligations contained in this Agreement relate to special,
unique and extraordinary matters and that a violation of any of the terms hereof or thereof would cause irreparable injury in
an amount which would be impossible to estimate or determine and for which any remedy at law would be inadequate. As such, the
parties agree that if either party fails or refuses to fulfill any of its obligations under this Agreement, then the other party
shall have the remedy of specific performance, which remedy shall be cumulative and nonexclusive and shall be in addition to any
other rights and remedies otherwise available under any other contract or at law or in equity and to which such party might be
entitled. The Shareholder therefore agrees that, in the event of any such breach or threatened breach of this Agreement or the
terms and conditions hereof by the Shareholder, the Company shall be entitled, in addition to all other available remedies, to
an injunction restraining any breach or threatened breach, without the necessity of showing economic loss and without any bond
or other security being required.

out of this Agreement or any matter related hereto may be brought in the courts of the State Texas and, by execution and delivery
of this Agreement, each party hereby submits to the jurisdiction of such courts. EACH PARTY HEREBY WAIVES ANY RIGHT IT MAY HAVE
TO A TRIAL BY JURY IN CONNECTION WITH ANY MATTER CONTESTED UNDER, OR ARISING OUT OF, THIS AGREEMENT.
