IMPORTANT TAX INFORMATION

Under current U.S. federal income tax law, a warrantholder who tenders Lighting Science Group Corporation warrant certificates that are accepted for exchange may be subject to backup withholding. In order to avoid such backup withholding, the warrantholder must provide the Exchange Agent with such warrantholder’s correct taxpayer identification number and certify that such warrantholder is not subject to such backup withholding by completing the Substitute Form W-9 provided herewith. In general, if a warrantholder is an individual, the taxpayer identification number is the Social Security number of such individual. If the Exchange Agent is not provided with the correct taxpayer identification number, the warrantholder may be subject to a $50 penalty imposed by the Internal Revenue Service. For further information concerning backup withholding and instructions for completing the Substitute Form W-9 (including how to obtain a taxpayer identification number if you do not have one and how to complete the Substitute Form W-9 if the warrant certificates are held in more than one name), consult the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9.

Certain warrantholders (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. In order to satisfy the Exchange Agent that a foreign individual qualifies as an exempt recipient, such warrantholders must submit a statement, signed under penalties of perjury, attesting to that individual’s exempt status, on a properly completed Form W-8BEN, or successor form. Such statements can be obtained from the Exchange Agent.

Failure to complete the Substitute Form W-9 will not, by itself, cause the warrant certificates to be deemed invalidly tendered. Backup withholding is not an additional federal income tax. Rather, the federal income tax liability of a person subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained provided that the required information is furnished to the Internal Revenue Service.

Privacy Act Notice. — Section 6109 requires most recipients of dividend, interest, or certain other income to give taxpayer identification numbers to payers who must report the payments to the IRS. The IRS uses the numbers for identification purposes and to help verify the accuracy of tax returns. The IRS may also provide this information to the Department of Justice for civil and criminal litigation and to cities, states and the District of Columbia to carry out their tax laws. The IRS may also disclose this information to other countries under a tax treaty, or to Federal and state agencies to enforce Federal nontax criminal laws and to combat terrorism. Payers must be given the numbers whether or not recipients are required to file tax returns. Payers must generally withhold a portion of taxable interest, dividend, and certain other payments to a payee who does not furnish a taxpayer identification number to a payer. Certain penalties may also apply.

Penalties

(1) Penalty for Failure to Furnish Taxpayer Identification Number. — If you fail to furnish your taxpayer identification number to a payer, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.
