     Re:     Waiver of Defaults and Amendment of Loan and Security Agreement.
             ---------------------------------------------------------------

Dear Curt:

     Reference is hereby made to that certain Loan and Security Agreement, dated
as of April 27, 2004 (as amended and modified, from time to time, the
"Agreement"; initially capitalized terms used but not defined herein shall have
the meanings ascribed to such terms in the Agreement), by and among, on the one
hand, Advanced Marketing Services, Inc., Publishers Group, Incorporated, and
Publishers Group West, Incorporated (collectively, jointly and severally, the
"Borrowers"), and, on the other hand, the lenders identified on the signatures
pages to the Agreement ("Lenders"), and Wells Fargo Foothill, Inc. ("Agent"), as
the arranger and administrative agent for the Lenders.

     Pursuant to Section 6.3(d) of the Agreement (as previously modified by
mutual agreement), Borrowers were required to deliver to Agent, with copies to
each Lender, on or before February 28, 2006, certain consolidated financial
statements of Parent and its Subsidiaries, audited by independent certified
public accountants, for the fiscal year ending March 31, 2004. Borrowers have
failed to provide the aforementioned financial statements within the prescribed
time period and such failure constitutes an Event of Default under the Agreement
(the "Reporting Default").

     In addition to the forgoing, Borrowers have failed to satisfy the EBITDA
related financial covenant set forth in Section 7.18(a)(i) of the Agreement for
the period ended December 31, 2005. The EBITDA covenant for the nine months
ended December 31, 2005 required the Borrowers to generate $2,500,000 of EBITDA
and the Borrowers reported $1,943,000. The failure to satisfy such covenant for
the applicable period constitutes an Event of Default under the Agreement (the
"EBITDA Default" and collectively with the Reporting Default, the "Defaults").

     1.      Limited Waiver.
             --------------

     Borrowers have requested that Agent and Lenders waive the Defaults for the
prescribed periods. Agent and Lenders hereby agree to waive the Reporting
Default as of February 28, 2006 and the EBITDA Default as of December 31, 2005
subject to the delivery by Borrowers to Agent (with a copy to each Lender) of
the consolidated financial statements of Parent and its Subsidiaries, audited by
independent certified public accountants, for the fiscal year ending March 31,
2004, on or before April 30, 2006. Borrowers acknowledge and agree that their
failure to satisfy the aforementioned requirement prior to the prescribed
deadline shall constitute an Event of Default under the Agreement.
