Yes. Your husband's employer can file an L1 extension 6 months in advance of the L1 expiration. The extension is filed with USCIS with form I-129, including all necessary supporting documents. At the same time, your L2 extension should be filed in the same petition package with form I-539.
Note that there is a 5 year limit to L1B and 7 year limit the L1A status. In some cases, it is advantageous to change to H1B if you intend to stay long-term, and have an employer willing to sponsor for a green card.
Foreign nationals apply for an extension of their stay in L1 or L2 status from the Citizenship and Immigration Service. In other words, CIS grants permission to stay in the Unites States.
When foreign nationals travel abroad, however, they need to return to the Unites States with a valid visa. Therefore, if you plan to travel outside of the Unites States after February 11, 2011, you will need to apply for a visa with the Department of State (the embassy or consulate). It would be best to apply for a new visa before the current visa expires.
