any term of this Supply Agreement, and such failure or breach is not cured to CARALOES reasonable satisfaction within five (5) days (in the case of a failure to make a payment) or thirty (30) days (in any other case) after receipt of notice
thereof by MANNATECH, or if MANNATECH fails to perform or observe any covenant or condition on its part to be performed or observed when required to be performed and observed, and such failure continues after the applicable grace period, if any,
specified in this Supply Agreement, CARALOE may refuse to make further deliveries hereunder and may terminate this Supply Agreement upon notice to MANNATECH, and in addition, shall have such other rights and remedies, including the right to recover

upon strict performance of any provision of this Supply Agreement be deemed a waiver by CARALOE of any rights of CARALOE arising out of such prior default; nor shall CARALOES failure to insist upon strict performance of any provision of this
Supply Agreement be deemed a waiver by CARALOE of any of its rights or remedies hereunder or under applicable law or a waiver by CARALOE of any subsequent default by MANNATECH in the performance of or compliance with any of the terms of this Supply
Agreement.

shall not constitute a waiver of any rights of MANNATECH and/or its MANUFACTURER arising out of such prior default; nor shall MANNATECHS and/or its MANUFACTURERs failure to insist upon strict performance of any provision of this Supply
Agreement be deemed a waiver by MANNATECH and/or its MANUFACTURER of any of its rights or remedies hereunder or under applicable law or a waiver by MANNATECH and/or its MANUFACTURER of any subsequent default by CARALOE in the performance of or
compliance with any of the terms of this Supply Agreement.
