Notes to Unaudited Pro Forma Condensed Combined Financial Statements

Note 1. Basis of Presentation

The unaudited pro forma condensed consolidating statements of income of Nexxus Lighting, Inc. (“Nexxus”) for the six months ended June 30, 2007 and the year ended December 31, 2006 give effect to the acquisition of Advanced Lighting Systems, Inc. (“ALS”) as if it had been completed on January 1, 2006. The unaudited pro forma condensed consolidating balance sheet as of June 30, 2007 gives effect to the acquisition of ALS as if it had occurred on June 30, 2007.

The unaudited pro forma condensed consolidating statements of income and unaudited pro forma condensed consolidated balance sheet were derived by adjusting Nexxus’s historical financial statements for the acquisition of ALS. The unaudited pro forma condensed consolidated balance sheet and unaudited pro forma condensed consolidated statements of income are provided for informational purposes only and should not be construed to be indicative of Nexxus’s financial position or results of operations had the transaction been consummated on the dates indicated and do not project Nexxus’s financial position or results of operations for any future period or date.

The unaudited pro forma condensed consolidating balance sheet and unaudited condensed consolidating statements of income and accompanying notes should be read in conjunction with Nexxus’s historical financial statements and related notes, Nexxus’s “Management’s Discussion and Analysis of Financial Condition and Results of Operation” contained in Nexxus’s Annual Report on Form 10-KSB for the year ended December 31, 2006 and Form 10-QSB for the six months ended June 30, 2007, and ALS’s financial statements presented herein.

Note 2. Preliminary Purchase Price

The unaudited pro forma condensed consolidating financial statements reflect a preliminary purchase price of $3,305,608 (including acquisition costs of $288,762, all of which are reflected as accrued liabilities). Of the total preliminary purchase price, $1,599,846 was assumed to be financed with borrowings as Nexxus’s available cash and short-term investment balances were not sufficient at January 1, 2006, plus 260,000 shares of common stock valued at $1,417,000 on the date of the acquisition. The purchase price is subject to change since stipulations in the purchase agreement, such as the working capital adjustment which is to be finalized during a 75 day period subsequent to the closing date, which has yet to be finalized. Note these amounts do not include any shares which could be made available to the seller of ALS through future earnouts as contemplated by the purchase agreement.

In the accompanying June 30, 2007 unaudited pro forma condensed consolidated balance sheet, the total purchase price is allocated to the tangible and identifiable intangible assets and the liabilities of ALS based on their estimated fair values as of the date of the acquisition in accordance with the purchase method of accounting.

The excess of the purchase price over the fair value of acquired assets and liabilities is allocated to goodwill as follows:

Note 3. Pro Forma Adjustments

The pro forma adjustments made herein are based upon management’s preliminary estimates of the value of the tangible and intangible assets acquired. These estimates are subject to finalization.

A – Reduction in Cash and Investments due to Acquisition: Cash and Investments were reduced to reflect the cash paid to the previous owner and the amount of debt paid off at the closing of the transaction.

B – Record fair market value of Fixed Assets Acquired: Fixed assets were recorded at fair market value at the date of acquisition. These pro forma calculations assume net book value of fixed assets approximates fair market value.

C – Increase in other intangible assets due to Acquisition: Other intangible assets were increased to reflect the recording of Goodwill (purchase price amount over the value of the assets acquired). See Note 2. Also includes the write off of deferred financing fees incurred in connection with obtaining financing that was paid off as part of the Acquisition and a write off of a previous technology licensing agreement between ALS and Nexxus.

D – Increase in accrued liabilities: Accrued liabilities increased to reflect the transaction costs of the acquisition of ALS.

E – Decrease in various debt and capital lease accounts: The decrease in the debt and capital leases reflect payoff of all amounts borrowed at the time of the acquisition.

F – Change in Equity accounts due to Acquisition: Reflects the change in the equity accounts due to the acquisition of ALS and issuance of shares to the seller of ALS.

G – Reduction in Interest Income and Decrease in Interest Expense due to Acquisition:

For the Six Months ended June 30, 2007: Interest income has been reduced to reflect a $1,599,846 reduction of Nexxus’ cash and short term investments, which is the amount of cash paid in connection with the ALS acquisition. As more fully discussed in Nexxus Annual Report on Form 10-KSB for the year ended December 31, 2006 and Form 10-QSB for the six months ended June 30, 2007, Nexxus raised capital in December 2006 which was sufficient to repay any borrowings assumed in the pro forma calculations in the consolidating statement of income for the year ended December 31, 2006. Additionally, interest expense was decreased for 2006 to reflect the payoff of ALS’ loans by Nexxus at the date of the merger.

For the Year ended December 31, 2006: Interest expense has been increased to reflect borrowings of $1,599,846 which Nexxus would have been required to borrow as Nexxus did not have sufficient cash and short term investments at January 1, 2006. Interest expense was also decreased to reflect the payoff of ALS’ loans by Nexxus at January 1, 2006.

H – Change in the Weighted Average Shares Outstanding: The weighted average shares outstanding have been increased to reflect the 260,000 shares issued in connection with the ALS acquisition. This does not include any shares available to the seller of ALS through future earnouts included in the purchase agreement.
