2.   Registration.
     ------------

     (a)  Demand Registration. At any time commencing six (6) months after
          -------------------
closing of the sale transaction contemplated by the aforesaid Asset Purchase
Agreement and ending two years after said closing ("Protected Period") if the
Company has not provided the Holders with an effective registration statement
permitting them to freely and lawfully sell their common stock Registrable
Securities during the Protected Period, then upon written request by the
Majority Holders made to the Company that the Company effect the registration
under the Securities Act of all or part of the Registrable Securities (a "Demand
Registration"), the Company will use its diligent efforts to effect the
registration under the Securities Act of the Registrable Securities that the
Company has been so requested to register by such Majority Holders within ninety
(90) days after receipt of such request or within forty-five (45) days after
receipt of such request if the Company is qualified to file a registration
statement on Commission Form S-3 or any successor or similar short-form
registration statement (collectively, "Commission Form S-3"). The Company must
effect Demand Registrations pursuant to this Section 2(a) to the extent such
registrations may be effected on Commission Form S-3, but the Company shall not
be obligated to effect more than one (1) Demand Registration hereunder on
Commission Form S-1 or any other similar Commission Form.

     (b)  Piggyback Registration. If the Company for itself or any of its
          ----------------------
security holders shall at any time or times during the Protected Period
determine to register under the Securities Act any shares of its capital stock
or other securities (other than (i) the registration of an offer, sale or other
disposition of securities solely to employees of, or other persons providing
services to, the Company, or any subsidiary pursuant to an employee or similar
benefit plan registered on Form S-8 or similar or successor forms or (ii)
relating to a merger, acquisition or other transaction of the type described in
Rule 145 under the Securities Act or a comparable or successor rule, registered
on Form S-4 or similar or successor forms), on each such occasion the Company
will notify each Holder of such determination at least thirty (30) days prior to
the filing of such registration statement, and upon the request of any Holder
given in writing within twenty (20) days after the receipt of such notice,
subject to Section 2(f), the Company will use its diligent efforts as soon as
practicable thereafter to cause any of the Registrable Securities specified by
any such Holder to be included in such registration statement to the extent such
registration is permissible under the Securities Act and subject to the
conditions of the Securities Act (a "Piggyback Registration"). The rights
                                     ----------------------
granted to the Holders pursuant to this Section 2(b) shall be subordinate to any
previously granted piggyback registration rights granted by the Company.

     (c)  Registration Statement Form. The Company shall, if permitted by law,
          ---------------------------
effect any registration requested under Section 2 by the filing of a
registration statement on Commission Form S-3 and shall use its diligent efforts
to take any action necessary to maintain its eligibility to utilize Commission
Form S-3 to permit resales as requested by the Holders with respect to
"Transactions Involving Secondary Offerings" as described in General Instruction
I.B.3 of Commission Form S-3; provided however, Holder shall have the right to
cause the Company to

                                       3
<PAGE>

satisfy the Holders' demand registration rights hereunder on SEC Form S-1 or
such similar form as then in existence.

     (d)  Expenses. The Company shall pay all Registration Expenses incurred in
          --------
connection with any Piggyback Registrations and any Demand Registrations.

     (e)  Effective Registration Statement. A Demand Registration or a Piggyback
          --------------------------------
Registration requested pursuant to Section 2(a) or Section 2(b), respectively,
shall not be deemed to have been effected unless the registration statement
filed with respect thereto in accordance with the Securities Act has become
effective with the Commission. Notwithstanding the foregoing, a registration
statement will not be deemed to have become effective if (i) after it has become
effective with the Commission, such registration is interfered with by any stop
order, injunction, or other order or requirement of the Commission or other
governmental agency or any court proceeding for any reason other than a
misrepresentation or omission by any Holder, or (ii) the conditions to closing
specified in the purchase agreement or underwriting agreement entered into in
connection with such registration are not satisfied.

     (f)  Priority in Registration. If a Demand Registration or a Piggyback
          ------------------------
Registration is an underwritten offering, and the managing Underwriters shall
give written advice to Majority Holders or the Company, as the case may be,
that, in their opinion, market conditions dictate that no more than a specified
maximum number of securities (the "Underwriter's Maximum Number") could
                                   ----------------------------
successfully be included in such registration, then the Company and the Holders
will be able to participate in such offering in the following order of priority:
(i) first, the Company shall be entitled to include in such registration that
number of securities that the Company proposes to offer and sell for its own
account in such registration and that does not exceed the Underwriter's Maximum
Number; (ii) second, the Company will be obligated and required to include in
such registration that number of shares of Registrable Securities that the
Holders thereof shall have requested to be included in such offering, along with
shares of the Company's common stock owned by holders of piggyback registration
rights issued hereinbefore who request to include their shares in such offering,
allocated between such holders and the Holders, first to holders of such rights
issued hereinbefore, and second to the Holders to the full extent of the
remaining portion of the Underwriter's Maximum Number.

     (g)  Acceptable Delays. Notwithstanding anything in this Section 2 to the
          -----------------
contrary, the Company shall have the right to delay any registration of
Registrable Securities requested pursuant to paragraph (a) of this Section 2 for
up to ninety (90) days if such registration would, in the judgment of the
Company's Board of Directors, substantially interfere with any material
transaction being considered at the time of receipt of the request from the
Holders.

     (h)  Exceptions to Registration. Notwithstanding anything in this Agreement
          --------------------------
to the contrary, the Company shall not be obligated to take any action to effect
registration, qualification or compliance with respect to its Registrable
Securities:

          (i)  in any jurisdiction that would require it to qualify generally to
do business where it is not already so qualified;

                                       4
<PAGE>

          (ii)  that would subject it to taxation in a jurisdiction in which it
is not already subject generally to taxation;

          (iii) resulting in registering its securities in any jurisdiction
outside the United States.

     3.   Registration Procedures.

               ------------------------------

covered by such registration, the Company will, and hereby does, indemnify and
hold harmless each Holder of Registrable Securities to be sold under such
registration statement, each such Holder's legal counsel, each other person who

required by such Underwriter as a condition to including the Registrable
Securities of the Holders in such registration) and each other person, if any,
who controls any such Holder or any such Underwriter within the meaning of the
Securities Act (collectively, the "Indemnified Parties"), against any losses,
claims, damages or liabilities, joint or several, to which the Holders or
Underwriter or controlling person may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions or
proceedings, whether commenced or threatened, in respect thereof) arise out of
or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any registration statement under which such
securities were registered under the Securities Act, any preliminary prospectus,
final prospectus or summary prospectus contained therein or any document
incorporated therein by reference, or any amendment or supplement thereto, or
any omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein in light of the
circumstances in which they were made not misleading, or arise out of any
violation by the Company of any rule or regulation promulgated under the
Securities Act or state securities law applicable to the Company and relating to
action or inaction required of the Company in connection with any such
registration, and the Company will reimburse the Indemnified Parties for any
legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, liability, action or
proceeding; provided, however, that the Company shall not be liable to any

Company, each officer of the Company and each other person, if any, who controls
the Company within the meaning of the Securities Act, with respect to any

prospectus contained therein, or any amendment or supplement thereto, if, and
only if, such statement or alleged statement or omission or alleged omission was
made in reliance upon and in conformity with information furnished in writing to
the Company directly by such person or entity specifically for use therein;
provided, however, that the obligation of any Holder hereunder shall be limited

          (c) Notices of Claims. Etc. Promptly after receipt by an Indemnified
              -----------------
Party of notice of the commencement of any action or proceeding involving a
claim referred to in the preceding subdivisions of this Section 6, such
Indemnified Party will, if a claim in respect thereof is to be made against a
party required to provide indemnification (an "Indemnifying Party"), give
written notice to the latter of the commencement of such action, provided,
                                                                 --------
however, that the failure of any Indemnified Party to give notice as provided
-------
herein shall not relieve the Indemnifying Party of its obligation under the
preceding subdivisions of this Section 6, except to the extent that the
Indemnifying Party is actually materially prejudiced by such failure to give
notice. In case any such action is brought against an Indemnified Party, unless
in such Indemnified Party's reasonable judgment a conflict of interest between
such Indemnified and indemnifying parties may exist in respect of such claim,
the Indemnifying Party shall 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, with counsel reasonably satisfactory to such
Indemnified Party, and after notice from the Indemnifying Party to such
Indemnified Party of its election so to assume the defense thereof, the
Indemnifying Party shall not be liable to such Indemnified Party for any legal
or other expenses subsequently incurred by the latter in connection with the
defense thereof other than reasonable costs of investigation. No Indemnifying
Party shall consent to entry of any judgment or enter into any settlement
without the consent of the Indemnified Party which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation.

          (d) Other Indemnification. Indemnification similar to that specified
              ---------------------
in the preceding subdivisions of this Section 6 (with appropriate modifications)
shall be given by the Company and each Holder of Registrable Securities included
in any registration statement 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.

          (e) Indemnification Payment. The indemnification required by this
              -----------------------
Section 6 shall be made by periodic payments of the amount thereof during the
course of the investigation or defense, to be made promptly, as and when bills
are received or expense, loss, damage or liability is incurred provided evidence
of such has been delivered to the Indemnifying Party.

          (f) Survival of Obligations. The obligations of the Company and of the
              -----------------------
Holders under this Section 6 shall survive the completion of any offering of
Registrable Securities under this Agreement.

          (g) Contribution. If the indemnification provided for in this Section
              ------------
6 is unavailable or insufficient to hold harmless an Indemnified Party, then
each Indemnifying Party shall contribute to the amount paid or payable to such
Indemnified Party as a result of the losses, claims, damages or liabilities
referred to in this Section 6 an amount or additional amount, as the case may
be, in such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party or parties on the one hand and the Indemnified Party on the
other in connection with the statements or omissions which resulted in such
losses, claims, demands or liabilities as well as any other relevant equitable
considerations. 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 parties on the one hand or the
Indemnified Party on the other and the parties' relative, intent, knowledge,
access to information and opportunity to correct or prevent such untrue
statement or omission. The amount paid to an Indemnified Party as a result of
the losses, claims, damages or liabilities referred to in the first sentence of
this Section 6(g) 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 is the subject of this Section 6. 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. The amount due from any
Holder pursuant to this Section 6(g) shall be limited to an amount equal to the
net proceeds received by such Holder upon the sale of Registrable Securities
sold on the offering covered by such registration.

7. Covenants Relating to Rule 144.
   ------------------------------

          With a view to making available the benefits of certain rules and
regulations of the Commission which may at any time permit the sale of
securities of the Company to the public without registration after such time as
a public market exists for the Common Stock of the Company, the Company agrees:

                                       11
<PAGE>

          (a) to make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act, at all times after
the effective date of the first registration under the Securities Act filed by
the Company for an offering of its securities to the general public;

          (b) to use its diligent efforts to then file with the Commission in a
timely manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act, as amended (at any time after it has become
subject to such reporting requirements); and

          (c) so long as a Holder owns any Registrable Securities, to furnish to
the Holder forthwith upon request a written statement by the Company as to its
compliance with the reporting requirements of said Rule 144 (at any time after
90 days after the effective date of the first registration statement filed by
the Company for an offering of its securities to the general public), and of the
Securities Act and the Exchange Act (at any time after it has become subject to
such reporting requirements) a copy of the most recent annual or quarterly
report of the Company, and such other reports and documents of the Company as a
Holder may reasonably request in availing itself of any rule or regulation of
the Commission allowing a Holder to sell any such securities without
registration.

8.   Other Registration Rights. The Company covenants and warrants that it shall
     -------------------------
not hereinafter grant to any Person any registration rights unless such rights
are subordinate to and not inconsistent with the rights granted or contained
herein, so long as any of the registration rights under this Agreement remain in
effect.

9.   Termination of Registration Rights. The right to cause the Company to
     ----------------------------------
effect the registration of Registrable Securities set forth herein shall
terminate when all Registrable Securities, (i) can be sold in any one three (3)
month period without registration pursuant to the terms of Rule 144 of the
Securities Act and (ii) the market for the Company's Common Stock is
sufficiently liquid to permit sale of such all of such within a three month
period without adversely affecting the market price.

10.  Miscellaneous.

          (a) Specific Performance. The parties hereto acknowledge that there
              --------------------
may be no adequate remedy at law if any party fails to perform any of its
obligations hereunder and that each party may be irreparably harmed by any such
failure, and accordingly agree that each party, in addition to any other remedy
to which it may be entitled at law or in equity, shall be entitled to compel
specific performance of the obligations of any other party under this Agreement
in accordance with the terms and conditions of this Agreement. Legal fees and
costs of enforcing this Agreement shall be awarded to the prevailing party.
