on a daily basis in exchange transactions or otherwise as we agree with the underwriters or agents. The agreement will provide
that any securities sold will be sold at prices related to the then prevailing market prices for our securities. Therefore, exact
figures regarding proceeds that will be raised or commissions to be paid cannot be determined as of the date of this prospectus.

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0 0 12pt; text-align: justify; text-indent: 0.5in">Section 14A:3-5
of the New Jersey Business Corporation Act (the &ldquo;NJBCA&rdquo;) gives the Registrant power to indemnify each of its directors
and officers against expenses and liabilities in connection with any proceeding involving him by reason of his being or having
been a director or officer if (a) he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the
best interests of the Registrant, and (b) with respect to any criminal proceeding, he had no reasonable cause to believe his conduct
was unlawful. However, in a proceeding by or in the right of the Registrant, there shall be no indemnification in respect of any
liabilities or expenses if the officer or director shall have been adjudged liable to the Registrant unless the Court in such proceeding
determines he is entitled to indemnity for such liabilities and/or expenses. No indemnification shall be made to or on behalf of
a director or officer if a judgment or other final adjudication adverse to such director or officer establishes that his acts or
omissions (a) were in breach of his duty of loyalty to the Registrant and its shareholders, (b) were not in good faith or involved
a knowing violation of law or (c) resulted in receipt by the director or officer of an improper personal benefit. The NJBCA defines
an act or omission in breach of a person's duty of loyalty as an act or omission which that person knows or believes to be contrary
to the best interests of the Corporation or its shareholders in connection with a matter in which he has a material conflict of
interest. If a director or officer is successful in a proceeding, the statute mandates that the Registrant indemnify him against
expenses.</P>

such director or officer or his legal representative may be made a party by reason of his being or having been such director or
officer, provided, (1) said action, suit, or proceeding shall be prosecuted against such director or officer or against his legal
representative to final determination, and it shall not be finally adjudged in said action, suit, or proceeding that he had been
derelict in the performance of his duties as such director or officer, or (2) said action, suit or proceeding shall be settled
or otherwise terminated as against such director or officer or his legal representative without a final determination on the merits,
and it shall be determined by the Board of Directors (or, at the option of the Board of Directors, by a disinterested person or

have with respect to the indemnification or reimbursement of directors, officers, or employees.&quot;</P>
