                  acquired in whole or in part, during the term of this
                  Agreement, it is agreed and understood Consultant will not be
                  requested or demanded by the Company to return any of the
                  shares of Common Stock paid to it hereunder. It is further
                  agreed that if at any time during the term of this agreement,
                  the Company or substantially all of the Company's assets are
                  merged with or acquired by another entity, or some other
                  change occurs in the legal entity that constitutes the
                  Company, the Consultant shall retain and will not be requested
                  by the Company to return any of the shares of Common Stock.
