Except in the event we make a fundamental change to the terms and conditions of the Rights Offering, all exercises of Rights are
irrevocable, even if you later change your mind. The irrevocability of your exercise will apply even if new information comes
to your attention or if the market price of our Common Stock falls below the Rights Offering subscription price of $[&nbsp;&nbsp;&nbsp;&nbsp;]
per share. Your exercise of the Rights will also remain irrevocable if the authorized period for the Rights Offering is extended

not need to exercise their warrants in order to receive Rights. As a result, the total number of Rights distributed will exceed
the number of shares of our Common Stock outstanding on the record date. This means that even if you exercise all of your Rights,
your percentage ownership of our Common Stock will likely decrease and your voting and other equity rights will be diluted by
the issuance of shares in the Rights Offering to subscribers and the Backstop Purchasers. The more of your Rights you exercise,
the less your voting and other equity rights will be diluted. If you do not exercise your Rights before the expiration of the

is the opinion of our outside counsel, Eilenberg &amp; Krause LLP, that for U.S. federal income tax purposes, our U.S. securityholders
should not be subject to recognition of income or loss in connection with the receipt or exercise of Rights. However, there is
a lack of authority directly addressing the application of the Internal Revenue Code to distributions of Rights and your receipt
of Rights may be treated as a taxable distribution. We therefore recommend that you consult with your own tax advisor regarding
your own specific tax situation and to assess the potential adverse tax consequences resulting from the receipt and exercise of
Rights and the receipt, ownership and disposition of Common Stock. See, &ldquo;Risk Factors&mdash;The receipt of Rights may be
treated as a taxable distribution to you.&rdquo; See also, &ldquo;Material U.S. Federal Income Tax Consequences.&rdquo;</FONT></P>

the post-effective amendment. In such event, we will issue a press release announcing the changes to the Rights Offering and the

return your subscription payment, the amendment may nonetheless adversely affect your Rights and any prospective return on your

is the opinion of our outside counsel, Eilenberg &amp; Krause LLP, that the distribution of Rights to a holder of shares of our
Common Stock or of rights to acquire shares of our Common Stock should be treated, for U.S. federal income tax purposes, as a
non-taxable distribution under Section 305(a) of the Code and the Treasury Regulations promulgated thereunder. However, there
is a lack of authority addressing the application of the Code to distributions of Rights. The Internal Revenue Service (the &ldquo;IRS&rdquo;)
could come to different conclusions than our tax counsel regarding the tax treatment for the receipt and exercise of Rights. The
opinion of our tax counsel regarding the tax-free treatment of the Rights distribution is not binding on the IRS, or the courts.
As such, there is significant uncertainty in regard to the tax treatment of the receipt and exercise of Rights. For example, if
our Rights Offering is deemed to be part of a &ldquo;disproportionate distribution&rdquo; under Section 305 of the Code, your
receipt of Rights may be treated as the receipt of a taxable distribution to you. A &ldquo;disproportionate distribution&rdquo;
is a distribution or a series of distributions, including deemed distributions, that would have the effect of the receipt of cash
or other property by some securityholders and an increase in the proportionate interest of other securityholders in the company&rsquo;s
assets or earnings and profits. Due to the lack of authority on the part of the IRS and the courts in regard to interpreting Code
Section 305 with respect to distributions of Rights, it is not reasonably possible to quantify the degree of uncertainty and risk
to the recipients of the Rights regarding potential adverse tax effects. If our tax counsel&rsquo;s opinion is finally determined
by the IRS or a court to be incorrect, whether on the basis that the issuance of the Rights is a &ldquo;disproportionate distribution&rdquo;
or otherwise, the fair market value of the Rights would be taxable to holders of our Common Stock as a dividend to the extent
of the holder&rsquo;s pro rata share of our current and accumulated earnings and profits, if any, with any excess being treated
as a return of capital to the extent thereof and then as capital gain. Each holder of our shares of Common Stock considering participating
in our Rights Offering is urged to consult with his, her or its own tax advisor prior to making any investment determination in
order to assess possible adverse tax consequences. Please see the section in this prospectus under the caption: &ldquo;Material
U.S. Federal Income Tax Consequences.&rdquo;</FONT></P>

LLC (&ldquo;Leap Tide&rdquo;), Michael Osterer (one of our Directors), and Gary Mohr (one of our Directors and, together with
Leap Tide and Mr. Osterer, the &ldquo;Backstop Purchasers&rdquo;), pursuant to which each Backstop Purchaser has agreed to exercise
its/his Rights in full in the Rights Offering and, upon expiration of the Rights Offering, to purchase from the Company (directly
or through an affiliate), at the price per share equal to the subscription price of $[&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;]
per share, any and all shares of Common Stock that other securityholders do not subscribe for in the Rights Offering (&ldquo;Unsubscribed
Rights Shares&rdquo;), subject to the respective terms, conditions and limitations of the Backstop Agreement. The Backstop Agreement
provides that, first, the three Backstop Purchasers shall each purchase one-third of the first $300,000 of aggregate subscription
price of Unsubscribed Rights Shares, and that Leap Tide shall then purchase any and all remaining Unsubscribed Rights Shares.
Should Mr. Osterer and/or Mr. Mohr fail to purchase their respective contractual portion of Unsubscribed Rights Shares in full,
Leap Tide would purchase such unpurchased Unsubscribed Rights Shares as well.</FONT></P>

and regulations or legal conclusions with respect thereto, constitutes the opinion of our outside counsel, Eilenberg &amp; Krause

(possibly with retroactive effect). The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable
state, local or non-U.S. tax laws are not discussed. We therefore recommend that each holder of our Common Stock consult its own
tax advisor with respect to the particular tax consequences of this offering or the related share issuance to such holder.</FONT></P>

is the opinion of our outside counsel, Eilenberg &amp; Krause LLP, that the distribution of the Rights should be treated as a
non-taxable stock dividend under Section 305(a) of the Code. However, there is a lack of authority directly addressing the application
of Section 305(a) of the Code to distributions of Rights, including ones that incorporate backstop commitments by certain securityholders,
and thus the application of Section 305(a) of the Code to the distribution of the Rights in our offering is uncertain. In addition,
our counsel&rsquo;s position is not binding on the IRS, or the courts. If this position is finally determined by the IRS or a
court to be incorrect, the fair market value of the rights would be taxable to participants in the Rights Offering as a dividend
to the extent of our current and accumulated earnings and profits, with any excess being treated as a return of basis to the extent
thereof and then as capital gain. Due to the lack of authority on the part of the IRS and the courts in regard to interpreting
Code Section 305 as applied to distributions of Rights, it is not reasonably possible to quantify the degree of uncertainty and
risk to the recipients of the Rights regarding potential adverse tax effects. <I>See,</I> &ldquo;Risk Factors&mdash;The receipt
of Rights may be treated as a taxable distribution to you.&rdquo;</FONT></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">The
distribution of the rights would be taxable under Section 305(b) of the Code if the Rights Offering were to be treated as a distribution
or part of a series of distributions that have the effect of the receipt of cash or other property by some of our securityholders
and an increase in the proportionate interest of our other securityholders in our assets or earning and profits. Distributions
having that effect are referred to as &ldquo;disproportionate distributions.&rdquo; For purposes of the definition of &ldquo;disproportionate
distributions&rdquo;, the term &ldquo;property&rdquo; includes money, securities and any other property, except that &ldquo;property&rdquo;
does not include stock in the corporation making the distribution or rights to acquire such stock. The reference to a &ldquo;series
of distributions&rdquo; encompasses all distributions of stock made or deemed made by a corporation which have the result of receipt
of cash or property by some securityholders and an increase in the proportionate interests of other securityholders. Under the
Treasury Regulations applicable to Section 305(b), where the receipt of cash or property occurs more than 36 months following
a distribution or series of distributions of stock, or where a distribution is made more than 36 months following the receipt
of cash or property, such distribution or distributions will be presumed not to result in the receipt of cash or property by some
securityholders and an increase in the proportionate interest of other securityholders, unless the receipt of cash or property
by some securityholders and the distribution or series of distributions are made pursuant to a plan. During the last 36 months,
we have not made any distributions of cash or non-stock property with respect to our Common Stock. In addition, within the last
36 months, we have not made any payments in cash or non-stock property of interest on previously outstanding convertible notes
or of dividends on previously outstanding preferred stock. Currently, we do not intend to pay any dividends on our Common Stock
(other than the issuance of the Rights in connection with this offering). In addition, many forms of taxable distributions under
Section 305(b) of the Code involve preferred stock, such as the distribution of convertible preferred stock in certain circumstances
pursuant to Section 305(b). Currently, we do not have any convertible debt or preferred stock outstanding, nor do we currently
intend to issue any convertible debt or preferred stock.</FONT></P>

the basis of the relevant facts discussed in the paragraph above, together with analysis of Section 305(b) of the Code and corresponding
Treasury Regulations, it is the opinion of our outside counsel, Eilenberg &amp; Krause LLP, that the distribution of the Rights
in the Rights Offering should not constitute an increase in the proportionate interest of some securityholders in the assets or
earnings and profits of the Company and that the Rights Offering should therefore not constitute part of a &ldquo;disproportionate
distribution,&rdquo; pursuant to Section 305(b) of the Code. However, due to lack of authority, the actual application of the
Code Section 305 rules to the Rights Offering (and any interest therein or obtained thereby) is uncertain. If our tax counsel&rsquo;s
opinion is determined by the IRS or a court to be incorrect, whether on the basis that the issuance of the Rights is a &ldquo;disproportionate
distribution&rdquo; or otherwise, the fair market value of the Rights would be taxable to you. <I>See,</I> &ldquo;Risk Factors&mdash;The

Certificate of Incorporation, as amended, and the Amended Bylaws of the Registrant provide that the Registrant shall indemnify
its officers, directors and certain others to the fullest extent permitted by the General Corporation Law of Delaware (&ldquo;DGCL&rdquo;).
Section 145 of the DGCL provides that the Registrant, as a Delaware corporation, is empowered, subject to certain procedures and
limitations, to indemnify any person against expenses (including attorney&rsquo;s fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with any threatened, pending or completed action, suit or proceeding
(including a derivative action) in which such person is made a party by reason of his being or having been a director, officer,
employee or agent of the Registrant (each, an &ldquo;Indemnitee&rdquo;); provided that the right of an Indemnitee to receive indemnification
is subject to the following limitations: (i) an Indemnitee is not entitled to indemnification unless he acted in good faith and
in a manner that he reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe such conduct was unlawful and (ii) in the case of a derivative
action, an Indemnitee is not entitled to indemnification in the event that he is judged to be liable to the Company (unless and
only to the extent that the court determines that the Indemnitee is fairly and reasonably entitled to indemnification for such
expenses as the court deems proper). The statute provides that indemnification pursuant to its provisions is not exclusive of
other rights of indemnification to which a person may be entitled under any bylaw, agreement, vote of stockholders or disinterested
directors, or otherwise.</FONT></P>

persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion
of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act, and is, therefore,
unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant
of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered,
the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.</FONT></P>
