      Agreement constitutes the legal, valid and binding obligation of such Party and is enforceable against it in accordance with its terms, subject to the effects of bankruptcy, insolvency, or other laws of general application affecting the enforcement
      of creditor rights and judicial principles affecting the availability of specific performance and general principles of equity.

     

    

    

    5.        Covenant not to Compete. For a period of the later of: (a) [***] after the

      Padagis, Sol-Gel will not directly or indirectly, and will cause its affiliates not to, promote, market, sell, distribute, develop, commercialize, or manufacture (or enter into any arrangement with any person or entity to develop, commercialize, or
      manufacture) any generic pharmaceutical product that competes with any Product. In addition to any other rights or remedies provided by this Agreement, Padagis will have the right to injunctive or other equitable relief to restrain any breach or
      threatened breach or otherwise to specifically enforce the provisions of this Section. Padagis acknowledges and agrees that money damages would be an inadequate remedy to compensate for the breach of this Section. Padagis and Sol-Gel intend all
      provisions of this Section to be enforced to the fullest extent permitted by applicable legal requirements. If any provision or term of this Section is held to be illegal, invalid, or unenforceable under present or future applicable legal
      requirements of any jurisdiction, such provision will be fully severable, and this Section will be construed and enforced in such jurisdiction as if such illegal, invalid or unenforceable provision were never a part hereof, and the remaining
      provisions will remain in full force in such jurisdiction and will not be affected by the illegal, invalid, or unenforceable provision, or by its severance. Without limiting the generality of the foregoing, if a court or arbitrator of any competent
      jurisdiction should determine that any of the restrictions contained in this Section are unreasonable in terms of scope, duration, geographic area or otherwise, such provision will be reformed in such jurisdiction to the extent necessary such that
      such restriction will be rendered enforceable to the fullest extent permitted by applicable legal requirements.
