&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Senior Secured Revolving Credit Facility&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;In December 2011,
the Company entered into a Loan and Security Agreement (the &amp;#147;&lt;i&gt;Loan Agreement&lt;/i&gt;&amp;#148;) with Partners for Growth III,
L.P. (&amp;#147;&lt;i&gt;PFG&lt;/i&gt;&amp;#148;) pursuant to which the Company obtained a two-year, $5,000,000 revolving credit facility from PFG
(the &amp;#147;&lt;i&gt;Revolving Credit Facility&lt;/i&gt;&amp;#148;). As additional consideration for entering into the Revolving Credit Facility,
the Company issued to PFG and two PFG affiliated entities 7-year warrants to purchase, for $0.11 per share, an aggregate of 15,000,000
shares of the Company&amp;#146;s common stock (the &amp;#147;&lt;i&gt;PFG Warrants&lt;/i&gt;&amp;#148;).&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;The maturity date
for the Revolving Credit Facility is December&amp;#160;14, 2013 (the &amp;#147;&lt;i&gt;Maturity Date&lt;/i&gt;&amp;#148;). Interest on the loan accrues
at the rate of 12%&amp;#160;per annum, payable monthly, with the principal balance payable on the Maturity Date. Both Costa Brava Partnership
III L.P. (&amp;#147;&lt;i&gt;Costa Brava&lt;/i&gt;&amp;#148;) and The Griffin Fund LP (&amp;#147;&lt;i&gt;Griffin&lt;/i&gt;&amp;#148;) have unconditionally guaranteed
repayment of $2,000,000 of the Company&amp;#146;s monetary obligations under the Loan Agreement with PFG, and are jointly and severally
responsible.&amp;#160;&amp;#160;See Note 17 for a further discussion regarding this unconditional guarantee.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;To secure the payment
of the Company&amp;#146;s obligations under the Loan Agreement, the Company granted to PFG a first position, continuing security interest
in substantially all of the Company&amp;#146;s assets, including substantially all of its intellectual property. In addition, Costa
Brava, Griffin and certain other existing creditors of the Company have agreed that, while any obligations remain outstanding by
the Company to PFG under the Loan Agreement, their security interests in and liens on the Company&amp;#146;s assets shall be subordinated
and junior to those of PFG.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;As of June 30, 2013,
the Company was not in compliance with the financial covenants in the Loan Agreement and Revolving Credit Facility. On August&amp;#160;21,
2012, the Company and PFG entered into a Forbearance, Limited Waiver and Consent under Loan Agreement (the &amp;#147;&lt;i&gt;Waiver&lt;/i&gt;&amp;#148;)
by which, subject to certain terms and conditions, PFG waived that default and consented to other actions taken or to be taken
by the Company, including the issuance of securities to finance the acquisition of Bivio. The Company agreed to pay to PFG a $30,000
fee and issue to PFG warrants to purchase 2,045,455 shares of common stock (the &amp;#147;&lt;i&gt;Waiver Warrants&lt;/i&gt;&amp;#148;). The exercise
price of the Waiver Warrants was equal to the lower of the Next Equity Financing Effective Price (&amp;#34;&lt;i&gt;NEFEP&lt;/i&gt;&amp;#34;) or
$0.11 per share.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;The Waiver, by its
terms, expired on September&amp;#160;30, 2012.&amp;#160;&amp;#160;As of September&amp;#160;28, 2012, in light of the Company&amp;#146;s continuing
non-compliance with the financial covenants in the Loan Agreement, the Company and PFG entered into an Extension of Forbearance
under Loan and Security Agreement (the &amp;#147;&lt;i&gt;Forbearance Extension&lt;/i&gt;&amp;#148;), pursuant to which the Company agreed to issue
to PFG warrants exercisable for 2,045,455 shares of the Company&amp;#146;s common stock per extension with an exercise price equal
to the lower of the NEFEP or $0.11.&amp;#160;&amp;#160;The table below summarized the various Forbearance Extensions along with the warrants
issued to PFG.&lt;/p&gt;

no shares have been exercised by PFG related to any of the shares issuable under the warrants related to the forbearance extensions.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;Senior Subordinated Secured Convertible 2012 Notes&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;Effective as of
September 28, 2012, the Company issued and sold to The Griffin Fund LP Senior Subordinated Secured Convertible Promissory Notes
due November 30, 2012 in the aggregate principal amount of $1.2 million (the &amp;#147;&lt;i&gt;2012 Notes&lt;/i&gt;&amp;#148;). The 2012 Notes are
convertible at $0.12 per share, or the price of shares sold by the Company to one or more investors and raising gross proceeds
to the Company of at least $1.0 million. Through the end of January 2013, the Company issued an additional $4.2 million of the
2012 Notes.&amp;#160;&amp;#160;Since the conversion price was not fixed, such instrument was considered to be a derivative.&amp;#160;&amp;#160;As
such, the Company recorded approximately $237,000 as a derivative liability and related debt discount.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;Senior Subordinated Secured Convertible 2013 Notes&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;On February 2, 2013,
the Company authorized the issuance of Senior Subordinated Convertible 2013 Notes (the &amp;#147;&lt;i&gt;2013 Notes&lt;/i&gt;&amp;#148;) that are
a part of a series of notes, along with the 2012 Notes, in the aggregate amount of $10.0 million. On March 7, 2013, the aggregate
principal amount of 2013 Notes available for issuance was increased from $10.0 million to $20.0 million. As a result, the Company&amp;#146;s
Board of Directors authorized an increase in the shares of common stock reserved for issuance under the Subordinated Notes from
27,777,778 shares to 55,555,556 shares. &amp;#160;As additional consideration for the purchase of the 2013 Notes, the Company issued
shares of its common stock to each investor with a value equal to 25% of the principal amount of the 2013 Notes purchased by such
investor.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;As of August 13,
2013, the holders of the 2013 Notes were entitled to 39,597,000 shares of the Company&amp;#146;s common stock, of which the Company
issued 21,079,000 shares with a value recorded to additional paid in capital of $2.2 million. All 2012 Notes outstanding in the
principal balance of $5.4 million as well as $0.2 million in paid-in-kind interest were cancelled and exchanged by each investor
for 2013 Notes.&lt;/p&gt;

&lt;p style="font: 12pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;During the three
months ended June 30, 2013, J.P. Turner &amp;#38; Company, L.L.C. (the &amp;#34;&lt;i&gt;Placement Agent&lt;/i&gt;&amp;#34;) raised $2.5 million under
the 2013 Notes. The Placement Agent received (i) cash commissions totaling $285,000, representing 15% of the gross proceeds (ii)
an expense allowance of $55,300, representing 3% of the gross proceeds, and (iii) warrants to purchase up to 257,440 shares of
common stock of the Company for $0.09 per share. The proceeds were used to fund the Company&amp;#146;s operations.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;The maturity date
of the 2013 Notes, including those placed by the Placement Agent discussed above, is the earlier of 6 months after issuance, or
the closing of a debt or equity financing resulting in gross proceeds to the Company in excess of $5.0 million (a &amp;#147;&lt;i&gt;Qualified
Financing&lt;/i&gt;&amp;#148;). However, the Holders may, at any time, convert the outstanding principal balance of their respective 2013
Notes into shares of the Company's common stock at a conversion price equal to $0.12 per share.&amp;#160;&amp;#160;Further, within fifteen
(15) business days after the closing of a Qualified Financing, each investor may convert the outstanding principal and interest
under their 2013 Note into the securities issued in the Qualified Financing, on the same terms and conditions as the other investors
in the Qualified Financing.&amp;#160; Since the conversion price was not fixed, such instrument was considered to be a derivative.
As such, the Company recorded approximately $2.1 million as a derivative liability and related debt discount. During the nine month
period ended June 30, 2013 the Company issued 2013 Notes in the amount of $11.9 million, inclusive of cancellation and exchange
of the 2012 Notes.&amp;#160;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;As of August 13,
2013 the Company has issued $15.3 million of the $20.0 aggregate amount of 2013 Notes, inclusive of cancellation and exchange of
the 2012 Notes.&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;In March 2011, the
Company issued and sold to two accredited investors, Costa Brava Partnership III L.P. (&amp;#147;&lt;i&gt;Costa Brava&lt;/i&gt;&amp;#148;) and The
Griffin Fund LP (&amp;#147;&lt;i&gt;Griffin&lt;/i&gt;&amp;#148;) 12% Senior Subordinated Secured Promissory Notes due July 31, 2013 (the &amp;#147;&lt;i&gt;Senior
Subordinated Notes&lt;/i&gt;&amp;#148;) in the aggregate principal amount of $4.0 million. In July 2011, the Senior Subordinated Notes were
amended to permit the holders to demand repayment any time on or after July&amp;#160;16, 2012, in partial consideration for permitting
the issuance of additional Subordinated Secured Convertible Promissory Notes as discussed below.&amp;#160;The owners of the Senior
Subordinated Notes have not demanded payment as of June 30, 2013 and through the date of the filing of these financial statements
with the Securities and Exchange Commission.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;&amp;#160;&amp;#160;&lt;/p&gt;

&lt;p style="font: 12pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;The Senior Subordinated
Notes bear interest at a rate of 12%&amp;#160;per annum paid by adding the amount of such interest to the outstanding principal amount
of the Senior Subordinated Notes as paid-in-kind interest. As a result of the addition of such interest, the outstanding principal
amount of the Senior Subordinated Notes at June 30, 2013 was $5.2 million. Furthermore, the Senior Subordinated Notes is convertible
at $0.11.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;The Senior Subordinated
Notes are secured by substantially all of the assets of the Company pursuant to Security Agreements dated March&amp;#160;16, 2011 and
March&amp;#160;31, 2011 between the Company and Costa Brava as representative of the Senior Subordinated Note holders, but the liens
securing the Senior Subordinated Notes are subordinate to the liens securing the indebtedness of the Company to PFG under the Senior
Secured Revolving Credit Facility.&lt;/p&gt;

&lt;p style="font: 12pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;Subordinated Secured Convertible
Promissory Notes&lt;/b&gt;&lt;/p&gt;

&lt;p style="font: 12pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;In December 2010,
the Company entered into a Securities Purchase Agreement with Costa Brava and Griffin, pursuant to which the Company issued and
sold to Costa Brava and Griffin 12% Subordinated Secured Convertible Notes due December&amp;#160;23, 2015 (the &amp;#147;&lt;i&gt;Subordinated
Notes&lt;/i&gt;&amp;#148;), in the aggregate principal amount of $7.8 million and, in March 2011, the Company sold additional Subordinated
Notes to Costa Brava and Griffin for an aggregate purchase price of $1.2 million. In July 2011, the Company sold Subordinated Notes
to five accredited investors, including Costa Brava and Griffin, in the aggregate principal amount of $5.0 million. In addition,
holders of existing notes with a principal balance of $1.1 million converted certain other notes outstanding at the time into Subordinated
Notes during the year ended September 30, 2011.&lt;/p&gt;

&lt;p style="font: 12pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;The Subordinated
Notes bear interest at a rate of 12%&amp;#160;per annum, due and payable quarterly. For the first two years of the term of the Subordinated
Notes, the Company has the option to pay all or a portion of the interest due on each interest payment date in shares of Common
stock, with the price per share calculated based on the weighted average price of the Common stock over the last 20 trading days
ending on the second trading day prior to the interest payment date. While the Revolving Credit Facility is outstanding, interest
on the Subordinated Notes that is not paid in shares of Common stock must be paid by adding the amount of such interest to the
outstanding principal amount of the Subordinated Notes as PIK interest. During the nine month period ended June 30, 2013, the Company
paid approximately $1.4 million of interest costs in the form of 13,821,000 shares of common stock. The principal and accrued,
but unpaid interest under the Subordinated Notes is convertible at the option of the holder into shares of the Common stock at
an initial conversion price of $0.07 per share. The conversion price is subject to a full price adjustment feature for certain
price dilutive issuances of securities by the Company, and proportional adjustment for events such as stock splits, dividends,
combinations, etc. Beginning after the first two years of the term of the Subordinated Notes, the Company may force the conversion
of the Subordinated Notes into Common stock if certain customary equity conditions have been satisfied and the volume weighted
average price of the Common stock is $0.25 or greater for 30 consecutive trading days. As of June 30, 2013, the Company has not
met the equity conditions to force the conversion of the Subordinated Notes.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 45pt"&gt;The Subordinated
Notes are secured by substantially all of the assets of the Company pursuant to a Security Agreement dated December&amp;#160;23, 2010
and July&amp;#160;1, 2011, as applicable, between the Company and Costa Brava as representative of the holders of Subordinated Note,
but the liens securing the Subordinated Notes are subordinate in right of payment to Loans issued pursuant to the Senior Secured
Revolving Credit Facility and the Senior Subordinated Notes.&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;&amp;#160;As a result
of the issuances of Subordinated Notes, including the 2013 Notes discussed above, the conversion of existing notes to Subordinated
Notes and the application of PIK interest, the aggregate principal balance of the Subordinated Notes at June 30, 2013, exclusive
of the effect of debt discounts, was $16.1 million. During the nine month period ended June 30, 2013, approximately $30,000 in
principal of Subordinated Notes was converted into approximately 438,000 shares of common stock.&amp;#160;&amp;#160;The balance of the
Subordinated Notes, net of unamortized discounts comprised of derivative liability, at June 30, 2013 was $7.9 million. The debt
discounts will be amortized over the term of the Subordinated Notes, unless such amortization is accelerated due to earlier conversion
of the Subordinated Notes pursuant to their terms.&lt;/p&gt;

Company entered into a Fifth Omnibus Amendment, dated as of February 12, 2013, with Costa Brava (the &amp;#147;&lt;i&gt;Fifth Omnibus Amendment&lt;/i&gt;&amp;#148;),
and the Sixth Omnibus dated as of April 22, 2013 (the &amp;#147;&lt;i&gt;Sixth Omnibus&lt;/i&gt;&amp;#148;) with the representative of the holders
of the 12% Subordinated Secured Convertible Notes due 2015 (the &amp;#34;&lt;i&gt;Promissory Notes&lt;/i&gt;&amp;#34;), and each of the holders of
the Promissory Notes, the 12% Senior Subordinated Promissory Notes due 2013 (the &amp;#34;&lt;i&gt;Senior Subordinated Notes&lt;/i&gt;&amp;#34;)
and the 2013 Notes, which amends and modifies the terms of the Promissory Notes, the Senior Subordinated Notes and the Security
Agreements (as defined in the Fifth Omnibus Amendment) to permit the issuance of the 2013 Notes, subordinate the liens securing
the Promissory Notes to the 2013 Notes, and make the Senior Subordinated Notes and the 2013 Notes rank &lt;i&gt;pari passu&lt;/i&gt; with one
another. Costa Brava is the Company's largest stockholder and one of its largest creditors.&lt;/p&gt;

Certain instruments, including debt and warrants, contain provisions that adjust the conversion or exercise price in the event
of certain dilutive issuances of securities, or exercise/conversion prices that are not fixed.&amp;#160;&amp;#160;These provisions required
the Company to book a derivative liability upon issuance and re-measured the fair value of the derivative liability to be $14,286,000
as of June 30, 2013 and $19,925,000 as of September 30, 2012.&lt;/p&gt;

&lt;p style="font: 12pt/normal Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 0.5in"&gt;The Company estimated
the fair value of the derivative liability using the Binomial Lattice pricing model with the following significant inputs, as outlined
below, to estimate the fair value of the derivative liability as of June 30, 2013 and September 30, 2012: &amp;#160;&lt;/p&gt;
