Item 1.01. Entry into a Material Definitive Agreement.

        The existing lease for Dorman Products, Inc.'s (the "Registrant's")
principal corporate offices and warehouse located at 3400 East Walnut Street,
Colmar, PA (the "Premises") will expire on December 28, 2007.  On December
12, 2007, Berman Real Estate Partnership ("BREP I") and the Registrant agreed
in writing to amend the lease for the Premises for the primary purpose of
extending the term of the lease for an additional five (5) year period.  The
new term of the lease will begin on December 29, 2007 and end December 28, 2012.
All other terms of the lease will remain the same.

        The lease is a triple net non-terminable lease, under which the
Registrant is responsible for all expenses attributable to the leased property
(including maintenance and repair) and for the conduct of its operations in
compliance with all applicable laws and regulations.  Under the lease, BREP
is entitled to an annual rent increase based on the Consumer Price Index, All
Urban Consumers  U.S. city Average, All Items.  The Registrant paid rent of
$3.89 psf ($1.3 million per year) in 2006 and $4.00 psf ($1.3 million per year)
in 2007.  Based on current Bureau of Labor Statistics data, it is anticipated
that the rent for 2008 will increase to $4.10 per square foot (assuming a CPI-U
index of 2.6%).  The approximate amount of rent expected to be paid over the
life of the five (5) year lease term is $7 million.

        BREP is a Pennsylvania limited partnership of which Richard Berman, the
Registrant's Chief Executive Officer, and Steven Berman, the Registrant's
President and Chief Operating Officer, are limited partners.
