FIRST INVESTORS TAX EXEMPT FUNDS PROSPECTUS

DATED MAY 1, 2007

The following information for the Insured Intermediate Tax Exempt Fund replaces the Annual Fund Operating Expenses table and Example in their entirety on page 18 of the prospectus.

Annual Fund Operating Expenses

(expenses that are deducted from Fund assets)


	Management Fees (1)	Distribution and Service (12b-1) Fees (2)	Other Expenses (3), (4)	Total Annual Fund Operating Expenses (3), (4)	Fee Waivers (1)	Net Expenses (3), (4)
Class A Shares	0.60%	0.30%	0.39%	1.29%	0.19%	1.10%
Class B Shares	0.60%	1.00%	0.39%	1.99%	0.19%	1.80%

(1) The Adviser has contractually agreed with the Fund’s Board of Trustees (“Board”) to waive Management Fees for the fiscal year ending December 31, 2007 to the extent that Total Annual Fund Operating Expenses exceed 0.95% for Class A shares and 1.65% for Class B shares. This waiver excludes any interest expenses. The Board may change or eliminate this fee waiver at any time.

(2) The Fund’s Class A Rule 12b-1 fee has been restated to reflect current fees.

(3) Other Expenses include 0.15% of interest expenses that are related to the Fund’s investments in inverse floaters. These expenses are liabilities with respect to interest paid on short-term floating rate notes issued by the trusts whose inverse floater certificates are held by the Fund. Under accounting rules, the Fund also recognizes additional income in an amount that directly corresponds to these expenses. These expenses also affected the Total Annual Fund Operating Expenses and Net Expenses. If those interest expenses were not included, Other Expenses, Total Annual Fund Operating Expenses and Net Expenses would have been 0.24%, 1.14% and 0.95%, respectively, for Class A shares and 0.24%, 1.84% and 1.65%, respectively, for Class B shares.

(4) The Fund has an expense offset arrangement that may reduce the Fund’s custodian fee based on the amount of cash maintained by the Fund with its custodian. Any such fee reductions are not reflected under Other Expenses, Total Annual Fund Operating Expenses or Net Expenses.

It assumes that (1) you invest $10,000 in the Fund for the time periods indicated; (2) your investment has a 5% return each year; and (3) the Fund’s operating expenses remain the same, except for year one, which is net of fees waived. Although your actual costs may be higher or lower, under these assumptions your costs would be:
