Other than securities offered to officers and directors, in the event that at any time prior to repayment of this Note DDL shall offer to sell any equity securities of any kind for cash, to any party, it shall first offer to Holder the right to acquire all or any part of such securities on the same terms and conditions as are proposed to the other party.

In addition to the acceleration rights set forth hereinabove, the Holder hereof shall be entitled to accelerate the entire unpaid balance and any accrued interest hereunder, forthwith as against the Maker hereof and any endorsers, upon the occurrence of any of the following events (a) in the event any party liable for the payment hereof shall make a general assignment for the benefit of creditors or if any bankruptcy, insolvency or reorganization proceeding of any nature under Federal or state statutes be commenced by or against any of them, or in the event a receiver shall be appointed, or a writ or order of attachment or garnishment be issued or made against any of the property, assets or income of any of them (b) failure of any party obligated hereunder to do all things necessary to preserve and maintain the value and collectability of any collateral now or hereafter securing the obligations created hereunder.

No delay by the Holder in enforcing any covenant or right hereunder shall be deemed a waiver of such covenant or right and no waiver by the Holder of any particular provision hereof shall be deemed a waiver of any other provisions or a continuing waiver of such particular provision and except as so expressly waived, all provisions hereof shall continue in full force and effect.
