     2.1 Registration Statement.

     (a) Within 120 days following the Closing, NAC shall prepare and file with
the SEC a registration statement (on such form as shall, in the opinion of
counsel to NAC, be appropriate for such filing) covering all of the Registrable
Securities (the registration statement contemplated by this Section 2.1 is
hereinafter referred to as the "REGISTRATION STATEMENT").

     (b) After filing, NAC shall diligently use commercially reasonable efforts
to cause such registration statement (and/or file a new registration statement)
to become and remain effective until the earlier of (i) the date as of which all
of the Registrable Securities covered thereby have been resold by the Holders
holding the same or (ii) such time as the Holders are free to resell all of the
Registrable Securities covered thereunder pursuant to Rule 144(k).

     (c) Each Holder shall fully and promptly cooperate with NAC in connection
with its performance of its obligations under this Section 2.1 and in connection
therewith shall promptly take all such actions (including, without limitation,
the providing of written information to NAC) as NAC may from time request.

     2.2 Obligations of NAC. Whenever required to effect the registration of any
Registrable Securities pursuant to Section 2.1 hereof, NAC shall, within a
commercially reasonably time:

         (a) Prepare and file with the SEC such amendments and supplements to
the Registration Statement and the prospectus used in connection with the
Registration Statement as may be necessary to comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by the
Registration Statement.

         (b) Furnish to the Holders such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and such other

                                        2
<PAGE>

documents as they may reasonably request in order to facilitate the disposition
of Registrable Securities owned by them.

         (c) Use commercially reasonable efforts to register and qualify the
securities covered by the Registration Statement under such other securities or
"Blue Sky" laws of such jurisdictions as shall be reasonably requested by the
Stockholder; provided, however, that NAC shall not be required in connection
therewith or as a condition thereto to qualify to do business or to file a
general consent to service of process in any such states or jurisdictions.

         (d) Notify each Holder holding any Registrable Securities covered by
the Registration Statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in the Registration Statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in light of the circumstances then existing.

     2.4 Expenses of Registration. NAC shall pay all Registration Expenses,
except that the Holders shall bear all Selling Expenses attributable to their
Registrable Securities being registered and fees of their counsel.

3.   INDEMNIFICATION

     3.1 To the extent permitted by law, NAC will indemnify and hold harmless
each Holder, the partners, officers and directors of each Holder, and each
Person, if any, who controls such Holder against any losses, claims, damages or
liabilities (joint or several) to which it/he/she or they may become subject
under the Securities Act, the Exchange Act or other federal or state law,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively a "VIOLATION") by NAC: (i) any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement, including any preliminary prospectus or final prospectus
contained therein or any amendments or supplements thereto, (ii) the omission or
alleged omission to state therein a material fact required to be stated therein,
or necessary to make the statements therein not misleading, or (iii) any
violation or alleged violation by NAC of the Securities Act, the Exchange Act,
any state securities law or any rule or regulation promulgated under the
Securities Act, the Exchange Act or any state securities law in connection with
the offering covered by the Registration Statement; and NAC will pay to each
such Holder, partner, officer, director or controlling person for any legal or
other expenses reasonably incurred by him/her/it in connection with
investigating or defending any such loss, claim, damage, liability or action if
it is finally and judicially determined that there was such a Violation;
provided, however, that the indemnity agreement contained in this Section 3.1
shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the written consent
of NAC, which consent shall not be unreasonably withheld, nor shall NAC be
liable in any such case for any such loss, claim, damage, liability or action to
the extent that it arises out of or is based upon (i) a Violation that occurs in
reliance upon, and in conformity with, information furnished by or on behalf of
any Holder for use in connection with such registration, (ii) such Holder's
failure to deliver, at the time required by the Securities Act, a final or
amended prospectus that corrects any actual or alleged untrue statement or
omission contained in any preliminary prospectus or prior prospectus if such
Holder previously has been provided such final or amended prospectus in
accordance with Section 2.2 hereof or otherwise, (iii) any offer or sale, or
solicitation of any offer, made by the indemnified party in any jurisdiction in
which the same is not

                                        3
<PAGE>

registered or otherwise permitted, unless such indemnified party has been
advised in writing by NAC that such offer or sale, or such solicitation of any
offer, is registered or otherwise permitted in such jurisdiction, or (iv) any
other breach or violation by an indemnified party of the Securities Act, the
Exchange Act or other federal or state law, exclusive of any such breach or
violation to the extent the same is the consequence of any untrue statement of a
material fact contained in the Registration Statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto, or the omission to state therein any material fact required
to be stated therein or necessary to make the statements stated therein not
misleading.

     3.2 To the extent permitted by law, each Holder will indemnify and hold
harmless NAC, each of its directors and officers and each Person, if any, who
controls NAC within the meaning of the Securities Act and any other Holder
selling securities under the Registration Statement or any of such other
Holder's partners, directors or officers or any Person who controls such other
Holder, against any losses, claims, damages or liabilities (joint or several) to
which NAC or any such director, officer, controlling person or such other
Holder, or partner, director, officer or controlling person of such other
Holder, may become subject under the Securities Act, the Exchange Act or other
federal or state law, insofar as such losses, claims, damages or liabilities (or
actions in respect thereto) arise out of or are based upon any Violation, in
each case to the extent that such Violation occurs in reliance upon, and in
conformity with, information furnished by, or on behalf of, such Holder for use
in connection with the Registration Statement; and each such Holder will pay any
legal or other expenses reasonably incurred by NAC or any such director,
officer, controlling person or other Holder, or partner, officer, director or
controlling person of such other Holder, in connection with investigating or
defending any such loss, claim, damage, liability or action if it is finally and
judicially determined that there was such a Violation; provided, however, that
the indemnity agreement contained in this Section 3.2 shall not apply to any
Holder with respect to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the written
consent of such Holder, which consent shall not be unreasonably withheld; and
provided, further, however, that in no event shall any indemnity under this
Section 3 exceed the net proceeds from the sale of Registrable Securities
covered by the Registration Statement.

     3.3 Promptly after receipt by an indemnified party under this Section 3 of
notice of the commencement of any action (including any governmental action)
with respect to which indemnification under this Section 3 may be sought by such
indemnified party, such indemnified party will, if a claim in respect thereof is
to be made against any indemnifying party under this Section 3, deliver to the
indemnifying party a written notice of the commencement thereof, and the
indemnifying party shall have the right to participate in, and (to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed) assume, the defense thereof with counsel selected by the
indemnifying party or parties with the consent of the indemnified party or
parties (which consent shall not be unreasonably withheld or delayed); provided,
however, that an indemnified party shall have the right to retain its own
counsel, with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding (provided, however, that under no circumstances shall
any indemnifying party be obligated to pay for more than one counsel
representing any or all of the parties intended to be indemnified hereunder).
The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action, if materially
prejudicial to its ability to defend such action, shall relieve such
indemnifying party of liability to the indemnified party under this Section 3,
but the omission so to

                                        4
<PAGE>

deliver written notice to the indemnifying party will not relieve it of any
liability that it may have to any indemnified party otherwise than under this
Section 3.

     3.4 If the indemnification provided for in this Section 3 is held by a
court of competent jurisdiction to be unavailable to an indemnified party with
respect to any losses, claims, damages or liabilities referred to herein, the
indemnifying party, in lieu of indemnifying such indemnified party thereunder,
shall to the extent permitted by applicable law contribute to the amount paid or
payable by such indemnified party as a result of such loss, claim, damage or
liability in such proportion as is appropriate to reflect the relative fault of
the indemnifying party, on the one hand, and of the indemnified party, on the
other hand, in connection with the Violation(s) that resulted in such loss,
claim, damage or liability, as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by a court of law by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission to state a material fact relates to information supplied by or
on behalf of the indemnifying party or by or on behalf of the indemnified party
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission; provided, however,
that in no event shall any contribution by a Holder hereunder exceed the net
proceeds from the sale of such Holder's Registrable Securities covered by the
Registration Statement.

     3.5 The obligations of NAC and the Holders under this Section 3 shall
survive completion of any offering of Registrable Securities in a registration
statement and the termination of this Agreement. No indemnifying party, in the
defense of any such claim or litigation, shall, except with the consent of each
indemnified party, consent to entry of any judgment or enter into any settlement
that 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.

4.   TRANSFER OF MERGER SHARES AND ASSIGNMENT OF REGISTRATION RIGHTS.

     4.1 Stockholder shall be entitled and permitted to sell or otherwise
transfer all or any of his Merger Shares (i) to any other Person who or that is
a member his immediate family or any trust for the benefit of one or more
members of his immediate family, provided that each such Person who has not
previously executed this Agreement shall have agreed in writing, in form and
substance reasonably acceptable to NAC and delivered to NAC, to be bound by this
Agreement, (ii) in or pursuant to a bona fide arm's-length transaction conducted
on or through a national or regional securities exchange or through the NASDAQ
system, or (iii) to any Person if (a) such Person (together with its affiliates)
will not, upon the consummation of such sale or other disposition, own fifteen
percent (15%) or more of the outstanding shares of Common Stock and (b) such
Person shall have agreed in writing (in form and substance reasonably acceptable
to NAC) to be bound by this Agreement (any Person referred to in this clause
(iii) or in the foregoing clause (i) is herein referred to as a "SUCCESSOR
STOCKHOLDER"); provided, however, that no sale or other transfer shall be
permitted under or pursuant to the preceding clause (ii) or (iii) if such sale
or other transfer is being made, directly or indirectly to, or coordinated with,
any Person who is acting (directly or indirectly) in concert with the
Stockholder. Any purported gift, donation, sale, transfer or other disposition
of any Merger Shares other than as permitted by the foregoing shall be null and
void and shall not be given any force or effect by NAC. Each Successor
Stockholder shall be subject to all of the prohibitions, conditions and other
restrictions contained herein as they apply to the Stockholder as the holder of
any Merger Shares.

     4.2 The rights to cause NAC to register Registrable Securities pursuant to
this Agreement may be assigned by a Holder to any Person who or that, as a
donee, assignee or transferee or otherwise, has acquired such Registrable
Securities in accordance with, and as contemplated by, the foregoing Section 4.1
but only if such donee, assignee or transferee shall have agreed in writing (in
form and substance reasonably acceptable to NAC) to be bound by this Agreement.

5.   RULE 144 REPORTING

     With a view to making available to the Holders the benefits of certain
rules and regulations of the SEC that may permit the sale of the Registrable
Securities to the public without registration, NAC agrees to use its
commercially reasonable efforts to:

          (a) Make and keep public information available, as those terms are
understood and defined in SEC Rule 144 or any similar or analogous rule
promulgated under the Securities Act;

          (b) File with the SEC, in a timely manner, all reports and other
documents required of NAC under the Exchange Act; and

          (c) So long as a Holder owns any Registrable Securities, furnish to
such Holder forthwith upon request: a written statement by NAC as to its
compliance with the reporting requirements of Rule 144 of the Securities Act and
of the Exchange Act; a copy of the most recent annual or quarterly report of
NAC; and such other reports and documents as a Holder may reasonably request in
availing himself, herself or itself of any rule or regulation of the SEC
allowing him, her or it to sell any such securities without registration.
