competent jurisdiction to be invalid, illegal, void or unenforceable, the
remainder of the terms, provisions, covenants and restrictions set forth herein
shall remain in full force and effect and shall in no way be affected, impaired
or invalidated, and the parties hereto shall use their commercially reasonable
efforts to find and employ an alternative means to achieve the same or
substantially the same result as that contemplated by such term, provision,
covenant or restriction. It is hereby stipulated and declared to be the
intention of the parties that they would have executed the remaining terms,
provisions, covenants and restrictions without including any of such that may be
hereafter declared invalid, illegal, void or unenforceable.

     

    18.           Construction. The
parties agree that each of them and/or their respective counsel has reviewed and
had an opportunity to revise this Agreement and, therefore, the normal rule of
construction to the effect that any ambiguities are to be resolved against the
drafting party shall not be employed in the interpretation of this Agreement or
any amendments hereto. In addition, each and every reference to share prices in
this Agreement shall be subject to adjustment for reverse and forward stock
splits, stock dividends, stock combinations and other similar transactions of
the Common Stock that occur after the date of this Agreement.

     

    19.           Entire
Agreement.  The Agreement, together with the exhibits and
schedules thereto, contain the entire understanding of the parties with respect
to the subject matter hereof and supersede all prior agreements and
understandings, oral or written, with respect to such matters, which the parties
acknowledge have been merged into such documents, exhibits and
schedules.

    20.           Independent Nature of
Holders’ Obligations and Rights.  The obligations of each
Holder hereunder are several and not joint with the obligations of any other
Holders hereunder, and no Holder shall be responsible in any way for the
performance of the obligations of any other Holder hereunder. Nothing contained
herein or in any other agreement or document delivered at any closing, and no
action taken by any Holder pursuant hereto, shall be deemed to constitute the
Holders as a partnership, an association, a joint venture or any other kind of
entity, or create a presumption that the Holders are in any way acting in
concert with respect to such obligations or the transactions contemplated by
this Agreement. Each Holder shall be entitled to protect and enforce its rights,
including without limitation the rights arising out of this Agreement, and it
shall not be necessary for any other Holder to be joined as an additional party
in any proceeding for such purpose.

     

    21.           Survival. All
warranties and representations (as of the date such warranties and
representations were made) made herein or in any certificate or other instrument
delivered by it or on its behalf under this Agreement shall be considered to
have been relied upon by the parties hereto and shall survive the issuance of
the New Warrants.
