                              AMENDED AND RESTATED
                          REGISTRATION RIGHTS AGREEMENT

         Amended and Restated Registration Rights Agreement (this "Agreement")
executed this 1st day of April, 2004, by and between DIGITAL RECORDERS, INC., a
North Carolina corporation (the "Company"), and DOLPHIN OFFSHORE PARTNERS, L.P.
(the "Holder").

         WHEREAS, it is contemplated under that certain Stock Purchase Agreement
by and between the Company and the Holder dated October 13, 2003 (as such may be
amended from time to time, the "Stock Purchase Agreement") and that certain
Stock Purchase Warrant dated as of October 13, 2003, by the Company in favor of
the Holder (the "Warrant Agreement"), that the Company provide the Holder with
certain registration rights, as set forth in that certain Registration Rights
Agreement dated as of October 13, 2003, by and between the parties hereto (the
"Original Agreement");

         WHEREAS, the Company and the Holder have entered into that certain
Clarification and Modification Agreement dated as of the date hereof, which
provides for, among other things, amendment of the terms of the Company's Series
F Convertible Preferred Stock to add a provision requiring the payment of
dividends thereon, which dividends will initially be payable in additional
shares of Series F Convertible Preferred Stock, and the termination of the
Warrant Agreement; and

         WHEREAS, the Clarification and Modification Agreement provides that the
Original Agreement shall be amended in the manner set forth herein, and the
parties desire to enter into this Agreement to reflect such amendments and to
amend and restate in its entirety the Original Agreement;

         NOW THEREFORE, in consideration of the mutual covenants and agreements
and for other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto hereby agree as follows:

                                    ARTICLE I
                              REQUIRED REGISTRATION

         1.1      Required Registration. Subject to Sections 1.5 and 5.2 hereof,
as soon as practicable after the date hereof, but in no event later than May 15,
2004 (the "Target Effective Date"), the Company shall, at its sole cost and
expense, cause a Registration Statement under the 1933 Act covering the resale
by Holder of all of the Conversion Shares (which may be the Registration
Statement on Form S-3, registration no. 333-111534, filed prior to the date
hereof) to be declared effective by the Commission, time being of the essence.
The Company will use its reasonable efforts to keep such Registration Statement
current and effective for at least two (2) years from the date hereof or until
such earlier date as the Company's registration obligations with respect to the
Conversion Shares terminate pursuant to Section 5.2 hereof. The Company
acknowledges and agrees that if such Registration Statement shall not be
declared effective by the Target Effective Date, assuming full cooperation by
the Holder (including compliance by the Holder with all its obligations under
Section 1.6 hereof), then the rate at which dividends accrue on the Preferred
Stock shall increase as provided in Section 2(d) of the Amended and Restated
Certificate of Designation dated on or about the date hereof setting forth the
terms and provisions of the Preferred Stock.

<PAGE>

         1.2      Demand Registration.

                  (a)      At any time during the period beginning on the date
         on which any Dividend Shares become issuable (upon the initial issuance
         as dividends of shares of Preferred Stock convertible into such
         Dividend Shares, as contemplated by clause (b) of the definition of
         "Preferred Stock" contained in Section 6.1), and ending on the earlier
         of two years after the final issue date of such shares of Preferred
         Stock or the date on which the Company's registration obligations with
         respect to the Dividend Shares terminate pursuant to Section 5.2
         hereof, the Holder may request the Company to register under the
         Securities Act all, but not less than all, of the Dividend Shares that
         the Holder then holds or has the right to acquire and that constitute
         Registrable Securities, for sale by such Holder in the manner specified
         in such request. The Company will use its reasonable efforts to
         expeditiously effect the registration of the Dividend Shares following
         such a request. The Holder shall have the right to require such a
         registration one (1) time, provided that if the requested registration
         is not effected as contemplated by Section 1.5, the Holder shall
         continue to have the rights specified in this Section 1.2 until such
         registration is effected in accordance herewith. The Company shall not
         be required to effect a registration pursuant to a request under this
         Section 1.2 within six (6) months after the filing of a registration
         statement relating to a public offering of securities by the Company.
         Any Registration Statement filed pursuant hereto may include, in
         addition to the Dividend Shares, such other shares of Common Stock or
         other securities of the Company for sale by the Company or other
         security holders of the Company as the Company may deem appropriate,
         provided that the inclusion of such additional securities does not
         unreasonably interfere with the Holder's ability to dispose of the
         Dividend Shares pursuant to such registration. The Company may satisfy
         its obligations under this Section 1.2 by amending the Registration
         Statement filed pursuant to Section 1.1 to add the Dividend Shares
         thereto, if appropriate and permitted under applicable rules of the
         Commission.

                  (b)      If at the time of any request to register Dividend
         Shares pursuant to this Section 1.2 the Company is engaged in
         discussions or negotiations regarding a possible acquisition or other
         significant corporate transaction that, in the good faith determination
         of the Company's Board of Directors, would be adversely affected by the
         requested registration to the material detriment of the Company, then
         the Company may at its option direct that such request be delayed for a
         period not in excess of sixty (60) days from the date of such request,
         such right to delay a request to be exercised by the Company not more
         than once in any one (1) year period.

         1.3      Short-Form Registration. Notwithstanding the foregoing, the
Company shall not be required to effect a registration pursuant to the foregoing
provisions of Section 1.1 or 1.2 if it is determined that (a) such registration
would not be permitted under applicable securities laws or the rules and
regulations of the Commission or (b) Form S-3 or a comparable "short form"
Registration Statement is not available to the Company for such purpose. In no
event shall the Company be required to file a Registration Statement on Form S-1
pursuant to this Agreement. Any failure to file the Registration Statement
required by Section 1.1 for the reasons stated in this paragraph would, however,
result in any applicable adjustments specified in the last sentence of Section
1.1.

<PAGE>

         1.4      Expenses. The Company will pay all of its Registration
Expenses in connection with the registrations required by Sections 1.1 and 1.2,
including any Registration Statement that is not deemed to be effected pursuant
to the provisions of Section 1.5 hereof.

         1.5      Effective Registration Statement. A registration pursuant to
Section 1.1 or 1.2 of this Agreement shall not be deemed to have been effected
(i) unless a Registration Statement with respect thereto has been declared
effective by the Commission, (ii) if after it has become effective, such
registration is interfered with by any stop order, injunction or other order or
requirement of the Commission or other governmental agency or court for any
reason or (iii) the Registration Statement does not remain continuously
effective until termination of the Company's registration obligations pursuant
to Section 5.2 hereof. If a registration pursuant to this Article I is deemed
not to have been effected as provided in this Section 1.5, then the Company
shall continue to be obligated to effect the registration required by Section
1.1 or 1.2.

         1.6      Obligations of the Holder.

                  (a)      In connection with any registration of Registrable
         Securities pursuant to Section 1.1 or 1.2, the Holder shall furnish to
         the Company in a timely manner all information regarding itself and the
         distribution of such Registrable Securities as may be required to be
         included in the Registration Statement and as the Company may from time
         to time reasonably request in order to effect the registration of such
         Registrable Securities, and shall otherwise cooperate with the Company
         to the extent reasonably necessary to effect such registration.

                  (b)      Each Holder agrees, that upon receipt of any notice
         from the Company of the happening of any event of the kind described in
         paragraph (f) of Article II hereof, the Holder will forthwith
         discontinue disposition of Registrable Securities covered by any
         Registration Statement or Prospectus until the Holder's receipt of the
         copies of the supplemented or amended Prospectus contemplated by such
         paragraph (f), or until it is advised in writing by the Company that
         the use of the applicable Prospectus may be resumed, and has received
         copies of any additional or supplemental filings that are incorporated
         by reference in such Prospectus, and, if so directed by the Company,
         the Holder will deliver to the Company (at the Company's expense) all
         copies, other than permanent file copies then in the Holder's
         possession, of the Prospectus covering such Registrable Securities
         current at the time of receipt of such notice.

                  (c)      If any Registrable Securities are to be sold in an
         underwritten offering, the Holder shall complete and execute all
         questionnaires, powers of attorney, indemnities, underwriting
         agreements (including customary indemnities by the selling
         stockholders) and other documents reasonably and customarily required
         under the terms of such underwriting arrangements.

<PAGE>

                                    ARTICLE II
                             REGISTRATION PROCEDURES

         Whenever any Registrable Securities are to be registered pursuant to
this Agreement, the Company will use reasonable efforts to effect the
registration of such Registrable Securities for sale in accordance with the
intended method or methods of disposition thereof as quickly as possible, and
pursuant thereto the Company will as expeditiously as reasonably possible:

                  (a)      prepare and file with the Commission a Registration
         Statement with respect to such Registrable Securities and use all
         reasonable efforts to cause such Registration Statement to become and
         remain effective for the period contemplated by Section 1.1 or 1.2;
         provided, that as promptly as practicable before filing a Registration
         Statement or Prospectus or any amendments or supplements thereto, the
         Company will (i) furnish to counsel selected by the Holder copies of
         all such documents proposed to be filed, and (ii) notify the Holder of
         (x) any request by the Commission to amend such Registration Statement
         or amend or supplement any Prospectus, or (y) any stop order issued or
         threatened by the Commission, and take all reasonable actions required
         to prevent the entry of such stop order or to promptly remove it if
         entered;

                  (b)      (i) prepare and file with the Commission such
         amendments and supplements to such Registration Statement and the
         Prospectus used in connection therewith as may be necessary to keep
         such Registration Statement effective for the period contemplated by
         Section 1.1 or 1.2, and (ii) comply with the provisions of the
         Securities Act with respect to the disposition of all securities
         covered by such Registration Statement during such period in accordance
         with the intended methods of disposition by the Holder set forth in
         such Registration Statement;

                  (c)      furnish to the Holder, without charge, such number of
         conformed copies of such Registration Statement, each amendment and
         supplement thereto, the Prospectus included in such Registration
         Statement (including each preliminary Prospectus and, in each case,
         including all exhibits) and such other documents as the Holder may
         reasonably request in order to facilitate the disposition of the
         Registrable Securities owned by it;

                  (d)      use all reasonable efforts to register or qualify
         such Registrable Securities under such other securities or blue sky
         laws of such jurisdictions in the United States as the Holder shall
         reasonably request, to keep such registration or qualification in
         effect for so long as such Registration Statement remains in effect and
         do any and all other acts and things which may be reasonably necessary
         or advisable to enable the Holder to consummate the disposition in such
         jurisdictions of the Registrable Securities owned by it; provided,
         however, that the Company will not be required to (i) qualify generally
         to do business in any jurisdiction where it would not otherwise be
         required to qualify but for this clause (d), (ii) subject itself to
         taxation in any such jurisdiction or (iii) consent to general service
         of process in any such jurisdiction;

                  (e)      use all reasonable efforts (if the offering is
         underwritten) to furnish to the Holder a signed copy, addressed to the
         Holder (and the underwriters, if any) of an opinion of counsel for the
         Company or special counsel to the selling stockholder, dated the
         effective date of such Registration Statement (and, if such
         Registration Statement includes an underwritten public offering, dated
         the date of the closing under the

<PAGE>

         underwriting agreement), covering substantially the same matters with
         respect to such Registration Statement (and the Prospectus included
         therein) as are customarily covered in opinions of issuer's counsel
         delivered to the underwriters in underwritten public offerings, and
         such other legal matters as the Holder (or the underwriters, if any)
         may reasonably request;

                  (f)      notify the Holder, at a time when a Prospectus
         relating thereto is required to be delivered under the Securities Act,
         of the happening of any event known to the Company as a result of which
         the Prospectus included in such Registration Statement, as then in
         effect, contains an untrue statement of a material fact or omits to
         state any fact required to be stated therein or necessary to make the
         statements therein not misleading in light of the circumstances under
         which they were made, and, at the request of the Holder, the Company
         will prepare and furnish to the Holder a reasonable number of copies of
         a supplement to or an amendment of such Prospectus as may be necessary
         so that, as thereafter delivered to the purchasers of such Registrable
         Securities, such Prospectus shall not include an untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein not misleading in
         the light of the circumstances under which they were made;

                  (g)      cause all such Registrable Securities to be listed on
         each securities exchange and quotation system on which similar
         securities issued by the Company are then listed and to enter into such
         customary agreements as may be required in furtherance thereof,
         including, without limitation, listing applications and indemnification
         agreements in customary form;

                  (h)      provide a transfer agent and registrar for all such
         Registrable Securities not later than the effective date of such
         Registration Statement;

                  (i)      make available for inspection by the Holder, any
         underwriter participating in any disposition pursuant to such
         Registration Statement and any attorney, accountant or other agent
         retained by the Holder or any such underwriter, all financial and other
         records, pertinent corporate documents and properties of the Company,
         and cause the Company's officers, directors, employees and independent
         accountants to supply all information reasonably requested by the
         Holder, any such underwriter, attorney, accountant or agent in
         connection with such Registration Statement to enable them to conduct a
         reasonable investigation within the meaning of the Securities Act;

                  (j)     subject to other provisions hereof, use all
         reasonable efforts to cause such Registrable Securities covered by such
         Registration Statement to be registered with or approved by such other
         governmental agencies or authorities or self-regulatory organizations
         as may be necessary to enable the sellers thereof to consummate the
         disposition of such Registrable Securities; and

                  (k)     promptly notify the Holder of the issuance of any
         stop order by the Commission or the issuance by any state securities
         commission or other regulatory authority of any order suspending the
         qualification or exemption from qualification of any of the Registrable
         Securities under state securities or "blue sky" laws, and use every
         reasonable effort to obtain the lifting at the earliest possible time
         of any stop order suspending the effectiveness of any Registration
         Statement or of any order preventing or suspending the use of any
         preliminary Prospectus.

                              REGISTRATION EXPENSES

         3.1      Registration Expenses. All Registration Expenses will be borne
as provided in Section 1.4 of this Agreement.

         3.2      SELLERS' EXPENSES. The Company shall have no obligation to pay
(a) any underwriting discounts or commissions or stock transfer taxes
attributable to the sale of Registrable Securities, which expenses will be borne
by all sellers of securities included in such registration in proportion to the
aggregate selling price of the securities to be so registered, or (b) any fees
or expenses of attorneys for the Holder or any other selling stockholder.

                                   ARTICLE IV
                                 INDEMNIFICATION

         4.1      Company's Indemnification Obligations. The Company agrees to
indemnify and hold harmless the Holder and each other Person, if any, who
controls the Holder within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act (collectively, the "Holder Indemnitees"):

                           (i)     against any and all loss, liability, claim,
                  damage or expense arising out of or based upon an untrue
                  statement or alleged untrue statement of a material fact
                  contained in any Registration Statement (or any amendment or
                  supplement thereto), including all documents incorporated
                  therein by reference, or in any preliminary Prospectus or
                  Prospectus (or any amendment or supplement thereto) or the
                  omission or alleged omission therefrom of a material fact
                  required to be stated therein or necessary to make the
                  statements therein, in light of the circumstances under which
                  they were made, not misleading;

                           (ii)      against any and all loss, liability, claim,
                  damage and expense to the extent of the aggregate amount paid
                  in settlement of any litigation, investigation or proceeding
                  by any governmental agency or body, commenced or threatened,
                  or of any claim based upon any such untrue statement or
                  omission or any such alleged untrue statement or omission, if
                  such settlement is effected with the written consent of the
                  Company; and

                           (iii)      against any and all reasonable expense
                  incurred by them in connection with investigating, preparing
                  or defending against any litigation, or investigation or
                  proceeding by any governmental agency or body, commenced or
                  threatened, or any claim based upon any such untrue statement
                  or omission or any such alleged untrue statement or omission,
                  to the extent that any such expense is not paid under clause
                  (i) or (ii) above;

provided, that this indemnity does not apply to any loss, liability, claim,
damage or expense to the extent arising out of an untrue statement or alleged
untrue statement or omission or alleged omission made in reliance upon and in
conformity with written information furnished to the

<PAGE>

Company by or on behalf of the Holder expressly for use in the preparation of
any Registration Statement (or any amendment or supplement thereto), including
all documents incorporated therein by reference, or in any preliminary
Prospectus or Prospectus (or any amendment or supplement thereto); and provided
further, that the Company will not be liable to the Holder or any other Holder
Indemnitee under the indemnity agreement in this Section 4.1, with respect to
any preliminary Prospectus or the final Prospectus or the final Prospectus as
amended or supplemented, as the case may be, to the extent that any such loss,
liability, claim, damage or expense of such Holder Indemnitee results from the
fact that the Holder sold Registrable Securities to a Person to whom there was
not sent or given, at or prior to the written confirmation of such sale, a copy
of the final Prospectus or of the final Prospectus as then amended or
supplemented, whichever is most recent, if the Company has previously and timely
furnished copies thereof to the Holder.

         4.2      Holder's Indemnification Obligations. In connection with any
Registration Statement in which the Holder is participating, the Holder agrees
to indemnify and hold harmless (in the same manner and to the same extent as set
forth in Section 4.1 of this Agreement) the Company and each Person, if any, who
controls the Company within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act with respect to any statement or alleged
statement in or omission or alleged omission from such Registration Statement,
any preliminary, final or summary Prospectus contained therein, or any amendment
or supplement thereto, if such statement or alleged statement or omission or
alleged omission was made in reliance upon and in conformity with information
furnished to the Company by or on behalf of the Holder. The obligations of each
Holder pursuant to this Section 4.2 (if there are more than one) are to be
several and not joint (however, husband and wife are to be treated as one
Holder); provided, that with respect to each claim pursuant to this Section 4.2,
each such Holder's maximum liability under this Section shall be limited to an
amount equal to the net proceeds actually received by such Holder (after
deducting any underwriting discount and expenses) from the sale of Registrable
Securities being sold pursuant to such Registration Statement or Prospectus by
such Holder.

         4.3      Notices; Defense; Settlement. Promptly after receipt by an
indemnified party hereunder of written notice of the commencement of any action
or proceeding involving a claim referred to in Section 4.1 or Section 4.2 of
this Agreement, such indemnified party will, if a claim in respect thereof is to
be made against an indemnifying party, give written notice to the latter of the
commencement of such action; provided, that the failure of any indemnified party
to give notice as provided herein shall not relieve the indemnifying party of
its obligations under Section 4.1 or Section 4.2 of this Agreement except to the
extent that the indemnifying party is actually prejudiced by such failure to
give notice. In case any such action is brought against an indemnified party,
the indemnifying party will be entitled to participate in and to assume the
defense thereof, jointly with any other indemnifying party similarly notified,
to the extent that it may wish, and after notice from the indemnifying party to
such indemnified party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such indemnified party for any legal or
other expenses subsequently incurred by the latter in connection with the
defense thereof, unless in such indemnified party's reasonable judgment, upon
the advice of counsel, a conflict of interest between such indemnified and
indemnifying parties may exist in respect of such claim, in which case the
indemnifying party shall not be liable for the fees and expenses of (i) more
than one counsel for all holders of Registrable Securities, selected by the
Holder or (ii) more than one counsel for the Company in connection with any one
action or

<PAGE>

separate but similar or related actions. An indemnifying party who is not
entitled to, or elects not to, assume the defense of a claim will not be
obligated to pay the fees and expenses of more than one counsel for all parties
indemnified by such indemnifying party with respect to such claim, unless in the
reasonable judgment of any indemnified party, based on advice of counsel, a
conflict of interest may exist between such indemnified party and any other of
such indemnified parties with respect to such claim, in which event the
indemnifying party shall be obligated to pay the fees and expenses of such
additional counsel or counsels. The indemnifying party will not, without the
prior written consent of each indemnified party, settle or compromise or consent
to the entry of any judgment in any pending or threatened claim, action, suit or
proceeding in respect of which indemnification may be sought hereunder (whether
or not such indemnified party or any Person who controls such indemnified party
is a party to such claim, action, suit or proceeding), unless such settlement,
compromise or consent includes an unconditional release of such indemnified
party from all liability arising out of such claim, action, suit or proceeding.
Notwithstanding anything to the contrary set forth herein, and without limiting
any of the rights set forth above, in any event, any party will have the right
to retain, at its own expense, counsel with respect to the defense of a claim.

         4.4      Indemnity Provision. The Company and the Holder shall provide
for the foregoing indemnity (with appropriate modifications) in any underwriting
agreement with respect to any required registration or other qualification of
securities under any Federal or state law or regulation of any governmental
authority other than the Securities Act.

         4.5      Contribution Based on Relative Fault. In order to provide for
just and equitable contribution if a claim for indemnification pursuant to the
indemnification provisions of this Article IV is made but it is found in a final
judgment by a court of competent jurisdiction (not subject to further appeal)
that such indemnification may not be enforced in such case, and the express
provisions hereof provide for indemnification in such case, then the
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of the losses, claims, damages or liabilities
referred to in Section 4.1 or Section 4.2 of this Agreement in such proportion
as is appropriate to reflect the relative fault of the indemnifying party on the
one hand, and the indemnified party on the other, in connection with statements
or omissions which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations, including,
without limitation, the relative benefits received by each parties from the
offering of the securities covered by such Registration Statement, the parties'
relative knowledge and access to information concerning the matter with respect
to which the claim was asserted and the opportunity to correct and prevent any
statement or omission. The relative fault shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the indemnifying party or the indemnified party and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statements or omission. The parties hereto agree
that it would not be just and equitable if contributions pursuant to this
Section 4.5 were to be determined by pro rata or per capita allocation or by any
other method of allocation which does not take account of the equitable
considerations referred to in the first sentence of this Section 4.5. The amount
paid by an indemnified party as a result of the losses, claims, damages or
liabilities referred to in the first sentence of this Section 4.5 shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any action or
claim (which shall be limited as provided in Section 4.3 of this Agreement if
the indemnifying

<PAGE>

party has assumed the defense of any such action in accordance with the
provisions thereof) which is the subject of this Section 4.5. Promptly after
receipt by an indemnified party under this Section 4.5 of notice of the
commencement of any action against such party in respect of which a claim for
contribution may be made against an indemnifying party under this Section 4.5,
such indemnified party shall notify the indemnifying party in writing of the
commencement thereof if the notice specified in Section 4.3 of this Agreement
has not been given with respect to such action; provided, that the omission to
so notify the indemnifying party shall not relieve the indemnifying party from
any liability which it may otherwise have to any indemnified party under this
Section 4.5, except to the extent that the indemnifying party is actually
prejudiced by such failure to give notice. The Company and the Holder agree with
each other, and will agree with the underwriters of the Registrable Securities,
if requested by such underwriters, that (i) the underwriters' portion of such
contribution shall not exceed the underwriting discount and (ii) that the amount
of such contribution by the Holder shall not exceed an amount equal to the net
proceeds actually received by the Holder from the sale of Registrable Securities
in the offering to which the losses, liabilities, claims, damages or expenses of
the indemnified parties relate. No Person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation.

         4.6      Payments. The indemnification required by this Article IV
shall be made by periodic payments of the amount thereof during the course of
the investigation or defense, as and when expense, loss, damage or liability is
incurred.

                                   ARTICLE V.
                TRANSFER AND TERMINATION OF REGISTRATION RIGHTS;

         5.1      Transfer of Rights. The Holder identified in the preamble of
this Agreement may transfer its rights to register such Holder's Registrable
Securities hereunder to any transferee of such Registrable Securities, provided
that such rights may not be transferred (a) to any person or entity who or which
is engaged in an activity or business directly competitive with any activity or
business of the Company or any subsidiary of the Company as presently conducted;
or (b) to any person or entity without the Company's prior written consent,
which shall not be unreasonably withheld; and provided further that the proposed
transferee enters into a written agreement with the Company, agreeing to be
bound by the terms and conditions hereof. As used in Agreement, "Holder" shall
refer to the Holder identified in the preamble of this Agreement and to each
permitted transferee of such Holder's rights pursuant to this Section 5.1, as
the context requires; provided that no Holder other than the Holder identified
in the preamble of this Agreement shall have the right to make any transfer or
assignment of rights under this Agreement.

         5.2   Termination of Rights. The registration rights of any Holder
of such rights hereunder and the registration obligations of the Company
hereunder with respect to Registrable Securities will terminate on the earliest
date at which such Registrable Securities (a) have been sold or (b) may be sold
(i) within a three-month period pursuant to the exemption from registration
provided under Rule 144 promulgated under the Securities Act, or (ii) pursuant
to the exemption from registration provided under Rule 144(k) promulgated under
the Securities Act.

outstanding. The failure of any party to enforce any of the provisions of this

not affect the right of such party thereafter to enforce each and every
provision of this Agreement in accordance with its terms.
