the number of Shares of Common Stock that a Selling Stockholder will beneficially own after termination of sales under this prospectus. However, for the purposes of the table below, we have assumed that, after completion of the offering, none of the

such person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the board of directors of the Corporation. The right to indemnification
conferred in this Section B shall be a contract right and shall include the right to be paid by the Corporation the expenses incurred in defending any such proceeding in advance of its final disposition; provided, however, that, if the General
Corporation Law of the State of Delaware requires, the payment of such expenses incurred by a director or officer in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such person while
a director or officer, including, without limitation, service to an employee benefit plan) in advance of the final disposition of a proceeding, shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such director
or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified under this Section or otherwise. The Corporation may, by action of its Board of Directors, provide
indemnification to employees and agents of the Corporation with the same scope and effect as the foregoing indemnification of directors and officers. </FONT></P>

the exercise of the Notes if the holder would, after conversion, beneficially own more than 9.99% of the Company&#146;s issued and outstanding Common Stock. Because both of the Investors currently beneficially own substantially more than 10% of the
Company&#146;s outstanding Common Stock, the Notes currently may not be converted at all unless the blocker is reset or waived (which requires at least 61 days prior written notice to the Company) or the Investors lower their beneficial ownership as
a percent of our outstanding shares (e.g., through a sale of stock, which would take a substantial amount of time based on our average daily trading volume, as described below). </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT
STYLE="font-family:Times New Roman" SIZE="2">Without regard to the blocker, the Notes, at the time of issuance, could have been converted into an aggregate of 37.5&nbsp;million shares of Common Stock (the &#147;Conversion Shares&#148;). The number
of Conversion Shares can grow substantially over the 10-year term of the Notes due to the potential interest payable under the Notes. Specifically, if: (a)&nbsp;the Notes remain outstanding through the maturity date in May 2021, and (b)&nbsp;all
interest payments due over the 10-year term of the Notes are paid in-kind, then the Notes would, at maturity, be convertible into a total of 271.2&nbsp;million shares of Common Stock (subject to the blocker provision). This 271.2&nbsp;million share
figure is the number of shares being registered under the Registration Statement (i.e., the Investors have asked to have the entire amount that could be issued over 10 years included in the Registration Statement). </FONT></P>

do not contain any adjustment mechanism, including anti-dilution adjustments, other than customary adjustments that would apply in the case of a stock split, reverse stock split and similar recapitalization event. Based on prior guidance provided by
senior members of the Staff, we believe that the absence of any adjustment mechanisms would not raise concerns among the Staff with respect to the Staff&#146;s interpretation of Rule 415. </FONT></P>

Investors initially invested in the Company in June 2007 and the other initially invested in August 2008. Since these initial investments, the Investors have purchased additional shares of Common Stock, including in a PIPE financing in 2009, and
then again most recently investing in the Company through the Financing. Since the time that the Investors acquired their initial 5% ownership stakes in the Company and were required to report their holdings on Schedule 13D/13G, they have not, to
our knowledge, sold any shares of Common Stock. We believe that this pattern of buying and holding demonstrates that the Investors did not purchase the Notes with the aim of engaging in a distribution and thereby acting as underwriters. </FONT></P>

holding period for Notes, for which &#147;tacking&#148; would be permitted under Rule 144) for 42 days as of the date of this letter. Additionally, because the Investors hold well in excess of 10% of the total outstanding shares, the Notes are not
presently convertible due to the &#147;blocker&#148; provision described above (and thus the underlying shares cannot be sold). If an Investor wished to waive the blocker, the earliest time at which the Investor could convert the Notes is 61 days
from the date of this letter (assuming no other changes to their holdings), resulting in a minimum holding period prior to conversion and sale of at least 103 days. This holding period is longer than the period required by the Staff for valid

 <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2"><I>The Circumstances Under Which They Received the Shares </I></FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">As described above, the securities covered by the Registration Statement became issuable in a valid private placement that complied in all respects with
the PIPEs Interpretation, Section&nbsp;4(2) of the Act and Regulation D promulgated thereunder. As noted above, the terms of the Notes contain no &#147;toxic&#148; provisions or other terms that would be expected to merit any special concerns by the
Staff. The Investors purchased their securities for investment and specifically represented that they were not acquiring their securities with the purpose or intent of effecting a distribution in violation of the Act. There is no evidence to suggest
that those representations are false. Based on reports of recent statements of policy of the Staff relating to Rule 415, we believe that the Financing falls squarely outside the area of Staff concern regarding its interpretation of Rule 415.
</FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">We are aware that the Staff may equate the registration of securities with a present intent to distribute these securities. However, we
respectively submit that such a perspective is at odds with both market practices and the Staff&#146;s own previous interpretive positions, including the PIPEs Interpretation. We also note that such a perspective is inconsistent with the prior
practice of the Investors, who currently have a total of approximately 3.5&nbsp;million shares of Company Common Stock registered for resale on Form S-3 (File No.&nbsp;333-167890), and since such registration statement was declared effective on
July&nbsp;8, 2010, none of the registered shares have been sold by the Investors or their affiliated funds. In fact, as noted above, the Investors have built up increasingly long positions in the Common Stock over a period of several years.
</FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">There are a number of reasons why investors in a PIPE transaction would want shares registered other than to effect an immediate resale. Many
private investment funds are required to mark their portfolios to market. If portfolio securities are not registered, such investors are typically required to mark down the book value of those securities to reflect an illiquidity discount. That
portfolio valuation does not depend on whether the Investors intend to dispose of their shares or to hold them for an indefinite period. In addition, the Investors are fiduciaries for their limited partners and other investors in their funds. As
such, the Investors have a common law duty to act prudently. Accordingly, we understand that they wish to have their securities in a more liquid form, whereas not registering the shares could prevent them from taking advantage of market
opportunities or from liquidating their investment if there is a fundamental shift in their investment judgment about the Company. Finally, registered shares of many issuers are eligible to be used as margin collateral under the Federal
Reserve&#146;s margin regulations. Restricted securities are not &#147;margin stock.&#148; </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">We further note that the PIPEs Interpretation
supports the conclusion that registration is not equivalent to a current intent to distribute. If registration did equate with such a distribution intent, then we believe that no PIPE transaction could ever occur because the mere fact of subsequent
registration would presumably negate an investor&#146;s prior representation of investment intent, which would in turn destroy any private placement exemption. However, the PIPEs Interpretation supports our view that an investor can have a valid
investment intent, even if the shares purchased are registered for resale at the time of closing. </FONT></P>

&#147;blocker&#148; provision) through open-market sales at the current average trading volume, it would take them between 1.2 and 4.9 years to do so, depending on how much of the future daily trading volume Investor sales represented (these
assumptions reflect a range of 100% to 25%). Looking to the full number of shares being registered on the Registration Statement, it would take the Investors between 8.9 and 35.8 years to fully sell, again assuming sales at the current average daily

STYLE="font-family:Times New Roman" SIZE="2">At the outset, we wish to note that the number of shares being registered is only <U>one</U> factor cited in the Interpretation to be considered by the Staff in applying Rule 415, and that the
multi-factorial nature of the analysis has been reiterated on numerous occasions by members of the Office of Chief Counsel. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">As we understand
the Staff&#146;s concerns relating to Rule 415 in this context, several years ago the Staff became increasingly concerned about public resales of securities purchased in &#147;toxic&#148; transactions. We understand that the Staff believed that
public investors could be harmed and did not have an appropriate understanding as to the nature of the investment being made or the negative impact that such transactions could have on the market prices of the issuers involved. In many of these
&#147;toxic&#148; transactions, an issuer would commit to issuing shares at a conversion price that floated in accordance with the market prices of the underlying common stock. When the offerings were announced, the stock prices often fell, with the
result that the issuer would ultimately issue significant blocks of stock &#151; in many cases well in excess of 100% of the shares previously outstanding. In these toxic situations, existing investors or investors who purchased shares after the
announcement of the transaction frequently faced unrelenting downward pressure on the value of their investments. In many of these cases, the shares held by non-participants in these transactions were ultimately rendered worthless. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">In order to combat the effects of these toxic transactions, we understand that the Office of Chief Counsel and the senior Staff members of the Division
began to look at ways to discourage toxic transactions and to limit the impact of these transactions. One way to do so was to limit the ability of the investors in those transactions to have their shares registered. </FONT></P>

 <P STYLE="margin-top:0px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">The Staff has advised our outside counsel that, in order to monitor these types of transactions, the Staff
was asked to compare the number of shares an issuer sought to register with the number of shares outstanding and held by non-affiliates prior to the offering in question. As we understand this mandate, the Staff was instructed to look more closely
at any situation where an offering involved more than approximately one-third of the public float. If an issuer sought to register more than one-third of its public float, the Staff was instructed to examine the transaction to see if it implicated
Staff concerns that a secondary offering might be a &#147;disguised&#148; primary offering for Rule 415 purposes. According to the Office of Chief Counsel, we understand that this test was intended to be a mere screening tool and was not intended to
substitute for a complete analysis of the factors cited in the Interpretation and discussed above and below. As far as we are aware, no rule-based rationale for the one-third threshold has ever been articulated by the Staff. In partial response to
concern over the Staff&#146;s interpretive position, we understand that the Staff&#146;s focus shifted to &#147;Extreme Convertible&#148; transactions to avoid disrupting legitimate PIPE transactions. As described above, we respectfully submit that
the terms of the Financing do not implicate any of the concerns leading to the focus on Extreme Convertible situations. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">The availability of
Rule 415 depends on whether the offering is made by selling stockholders or deemed to be made by or on behalf of the issuer. In order for the Staff to determine that the offering is really being made on behalf of the issuer, the Staff must conclude
that the selling stockholders are seeking to effect a distribution of the shares. However, if the Staff&#146;s concern is that a distribution is taking place, we submit that the number of shares being registered should be one of the less important
factors in the Staff&#146;s analysis (i.e., an illegal distribution of shares can take place when the amount of shares involved is less than one-third of the non-affiliate float). In fact, for the reasons noted above relating to the relative
illiquidity of the Company&#146;s securities, we submit that it would be significantly easier to effect an illegal distribution when the number of shares involved is relatively small in relation to the shares outstanding or the public float. As
demonstrated above, when investors buy a large stake of a small public company such as ours, it is virtually impossible for the investors to exit the stock in market transactions. Contrary to the Staff&#146;s screening criteria, we submit that the
larger the investment, the harder it may be for an investor to effect a distribution, particularly in the case of a small public company with a limited trading market. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT
STYLE="font-family:Times New Roman" SIZE="2">We further submit that limiting resale offerings to one-third of the public float seemingly contradicts other interpretative positions of the Staff. For example, Interpretation 612.12 describes a scenario
where a holder of 73% of the outstanding stock would be able to effect a valid secondary offering. The interpretation states, in relevant part: </FONT></P> <P STYLE="font-size:6px;margin-top:0px;margin-bottom:0px">&nbsp;</P>

 <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">These interpretive positions support our belief that the holder of well in excess of one-third of the

<P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">A singular focus on the number of shares being registered appears reminiscent of the &#147;presumptive underwriter&#148; doctrine, under which the Staff
previously took the position that the sale of more than 10% of the outstanding registered stock of an issuer made the investor a &#147;presumptive underwriter&#148; of the offering. We note that the presumptive underwriter doctrine was abandoned by
the Staff more than 20 years ago. <U>See</U> American Council of Life Insurance (avail. June&nbsp;10, 1983). More recent rule making has continued this trend away from this doctrine. <U>See</U> Securities Act Release No.&nbsp;33-8869 (December 6,
2007) (eliminating the &#147;presumptive underwriter&#148; provisions of Rule 145(c) and (d)&nbsp;in most cases). Accordingly, we do not believe that there is any basis to apply the doctrine here. </FONT></P>
<P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2">However, even if the number of shares registered is the sole focus of the inquiry, we do not believe that the Financing should raise significant concerns
about a &#147;disguised&#148; primary offering based on the number of shares the Company seeks to register. We note that the number of shares that we are registering represents the shares that would potentially be issuable at the end of the 10-year
term of the Notes; at present, a significantly smaller number of shares (37.5 million) is presently issuable (assuming that the &#147;blocker&#148; was not in place). </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT
STYLE="font-family:Times New Roman" SIZE="2">Based on the foregoing facts, we believe that the Company should be entitled to register all of the shares it is seeking to cover in the Registration Statement. </FONT></P>

STYLE="font-family:Times New Roman" SIZE="2">None of the Investors are in the business of underwriting securities. As described above, the Investors are private investment funds that buy and sell portfolio securities for their own accounts. All of
the Investors represented at the time of purchase that they were buying for their own accounts, for investment, and not with an intention to distribute in violation of the Act. There is no allegation that those representations and warranties are
untrue and no factual basis for any such allegation. </FONT></P> <P STYLE="margin-top:12px;margin-bottom:0px"><FONT STYLE="font-family:Times New Roman" SIZE="2"><I>Whether Under All the Circumstances it Appears that the Seller is Acting as a Conduit

as conduits for the Company. The Investors made fundamental decisions to invest in the Company, have held their securities for a period of time that exceeds the periods sanctioned in the Staff&#146;s PIPEs Interpretation, have represented their
investment intent and disclaimed any intent to illegally distribute their shares and really have no alternative but to hold their shares for a period of years, given the limited trading volume in the Company&#146;s securities. We believe that the
number of shares covered by the Registration Statement that are potentially presently issuable (i.e., not at the end of the 10-year term of the Notes) is reasonable in relation to other transactions that have been reviewed and approved by the Staff.
Additionally, we note that none of the Investors are in the business of underwriting securities. In these circumstances we believe that the offering the Company seeks to register is a valid secondary offering and may proceed consistent with Rule
415. </FONT></P>

Company&#146;s common stock, which was established in 2007. The short position is valued at approximately $12,000, based on the current market price of the Company&#146;s common stock (i.e., the value of the securities needed to cover). We
respectfully submit that disclosure of this short position is not material and is unrelated to the offering of the Notes and the sale of the shares under the prospectus. Accordingly, we believe that this position need not be disclosed in the
prospectus. Additionally, we note that the selling stockholders did provide representations in the Purchase Agreement that no short positions were established within 30 days prior to entering into the agreement and no such positions will be
established prior to the date of effectiveness of the Registration Statement. </FONT></P> <P STYLE="font-size:12px;margin-top:0px;margin-bottom:0px">&nbsp;</P>
