EXHIBIT 4.2
                                     FORM OF
                                    AMENDMENT
                                       TO
                                RIGHTS AGREEMENT

         This Amendment to Rights Agreement ("Amendment") is made and entered
into effective as of December 18, 2000, by and between Digital Recorders, Inc.,
a North Carolina corporation ("Company") and Continental Stock Transfer & Trust
Company, a New York corporation ("Rights Agent").

                                    Recitals

         WHEREAS, Company and Rights Agent entered into that certain Rights
Agreement, dated as of December 19, 1999; and

         WHEREAS, the Board of Directors (the "Board") of Company approved an
amendment to the Rights Agreement as set forth herein, which amendment has not
previously been documented; and

         WHEREAS, Company and Rights Agent desire to enter into this Amendment
to evidence the Board's amendment of the Rights Agreement as set forth herein;

         NOW, THEREFORE, in consideration of the mutual promises and covenants
contained herein, the parties hereto agree as follows:

         1. Section 1(a). By resolution approved and adopted as of December 20,
2000, the Board agreed to amend Section 1(a) of the Rights Agreement to
specifically exclude certain acquisitions of Common Shares of the Company in
determining whether a Person is an "Acquiring Person" as defined in the Rights
Agreement. Accordingly, Section 1(a) of the Rights Agreement is hereby amended
by deleting Section 1(a) in its entirety and replacing it with the following
Section 1(a), with the added substantive language indicated by italics:

                           (a) "Acquiring Person" shall mean any Person who or
                  which, together with all Affiliates and Associates of such
                  Person, shall be the Beneficial Owner of fifteen percent (15%)
                  or more of the Common Shares of the Company then outstanding
                  but shall not include (i) the Company, (ii) any Subsidiary of
                  the Company, (iii) any employee benefit plan of the Company or
                  any Subsidiary of the Company, or (iv) any Person or entity
                  holding Common Shares for or pursuant to the terms of any such
                  employee benefit plan. Notwithstanding the foregoing, (1) no
                  Person shall become an "Acquiring Person" as the result of an
                  acquisition of Common Shares by the Company which, by reducing
                  the number of shares outstanding, increases the proportionate
                  number of shares beneficially owned by such Person to 15% (or
                  such other percentage as would otherwise result in such Person
                  becoming an Acquiring Person) or more of the Common Shares of
                  the Company then outstanding; provided, however, that if a
                  Person shall so become the Beneficial Owner of 15% (or such
                  other percentage) or




                  more of the Common Shares of the Company then outstanding by
                  reason of an acquisition of Common Shares by the Company and
                  shall, after such share purchases by the Company, become the
                  Beneficial Owner of an additional one percent (1%) of the
                  outstanding Common Shares of the Company (other than pursuant
                  to a dividend or distribution paid or made by the Company on
                  the outstanding Common Shares or pursuant to a share split or
                  subdivision of the outstanding Common Shares, or pursuant to
                  any other acquisition of common shares directly from the
                  Company), then such Person shall be deemed to be an "Acquiring
                  Person;" (2) no person shall become an "Acquiring Person" as
                  the result of an acquisition of common shares directly from
                  the Company which increases the proportionate number of shares
                  beneficially owned by such person to 15% (or such other
                  percentage as would otherwise result in such person becoming
                  an Acquiring Person) or more of the common shares of the
                  Company then outstanding; provided, however, that if a person
                  shall so become the beneficial owner of 15% (or such other
                  percentage) or more of the common shares of the Company then
                  outstanding by reason of an acquisition of common shares
                  directly from the Company and shall, after such acquisition of
                  shares from the Company, become the beneficial owner of an
                  additional one percent (1%) of the outstanding common shares
                  of the Company (other than pursuant to a dividend or
                  distribution paid or made by the Company on the outstanding
                  common shares, or pursuant to a share split or subdivision of
                  the outstanding common shares, or pursuant to any other
                  acquisition of common shares directly from the Company), then
                  such person shall be deemed to be an "Acquiring Person;" and
                  (3) if the Board of Directors of the Company determines in
                  good faith that a Person who would otherwise be an "Acquiring
                  Person," as defined pursuant to the foregoing provisions of
                  this paragraph, has become such inadvertently, and such Person
                  divests as promptly as practicable a sufficient number of
                  Common Shares so that such Person would no longer be an
                  "Acquiring Person," as defined pursuant to the foregoing
                  provisions of this paragraph, then such Person shall not be
                  deemed to have become an "Acquiring Person" for any purposes
                  of this Agreement.

         2. Defined Terms. Capitalized terms that are used herein and not
otherwise defined shall have the meanings assigned to them in the Rights
Agreement.

         3. No Further Amendment. All other terms and provisions of the Rights
Agreement not expressly modified by this Amendment shall remain in full force
and effect and are hereby expressly ratified and confirmed.

                                  * * * * * * *
