NPDC Warrants.

2.2 Form S-3 Registration. NPDC shall use its best efforts to prepare and file,
as promptly as practicable, and in any event within 60 days, after the date on
which NPDC is eligible to file Form S-3 for this purpose, with the SEC a
registration statement on Form S-3 or on such form as is then available under
the Securities Act covering the Registrable Securities held by the Holders.

2.3      Demand Registration.

(a)      Subject to the conditions of this Section 2.3, if NPDC receives a
         request from Holders who own, or on exercise of all NPDC Warrants would
         own, 25% of the Registrable Securities then outstanding (the
         "Initiating Holders") that NPDC file a registration statement under the
         Securities Act covering the registration of all or a part of such
         Initiating Holders' Registrable Securities, then NPDC shall, within 15
         days of the receipt thereof, give notice of such request to all
         Holders, and use its best efforts to effect, as soon as practicable,
         the registration under the Securities Act of all Registrable Securities
         that the Initiating Holders request to be registered and all
         Registrable Securities owned by any other Holder which notifies NPDC in
         writing, within 30 days after receipt of NPDC's notice contemplated in
         this Section 2.3, that it intends to participate in the demand
         registration (such notification to include the number of Registrable
         Securities sought to be included and the intended method or methods of
         distribution of such Registrable Securities), subject to and in
         accordance with the terms, conditions, procedures, and limitations
         contained in this Agreement. The Initiating Holders may at any time
         prior to the effective date of the registration statement relating to a
         requested registration under this Section 2.3 revoke their request by
         providing written notice to NPDC, in which case the Registration
         Expenses will be borne in accordance with Section 2.6.

(b)      NPDC shall not be required to effect a registration pursuant to this
         Section 2.3:

(i)      during the period of 120 days commencing on the date on which NPDC
         becomes eligible to use Form S-3 as contemplated by Section 2.2, so
         long as NPDC is in compliance with its obligations under Section 2.2,
         or at any time when a registration statement filed pursuant to Section
         2.2 is effective under the Securities Act;

(ii)     after NPDC has effected two registrations pursuant to this Section 2.3,
         provided, however, that a registration shall not count as having been
         effected unless and until it has become effective, and unless and until
         the Holders participating in such registration shall have had the
         opportunity to register and sell 100% of the Registrable Securities
         initially requested to be registered pursuant thereto, except that a
         registration the request for which has been revoked shall count as
         having been effected unless the revocation is based upon material





         adverse information concerning NPDC of which the Initiating Holders
         were not aware at the time of their request;

(iii)    during the period starting with the date of filing of, and ending on
         the date 90 days following the effective date of, a registration
         statement pertaining to any underwritten public offering made pursuant
         to this Section 2.3; provided that NPDC makes reasonable and diligent
         good faith efforts to cause such registration statement to become
         effective; or

(iv)     during the period starting with the date of filing of, and ending on
         the date 90 days following the effective date of, a registration
         statement pertaining to any underwritten public offering in which the
         Holders were given the opportunity to participate pursuant to Section
         2.4 for not less than 20% of the amount of the offering; provided that
         NPDC uses best efforts to cause such registration statement to become
         effective.

(c)      If the Initiating Holders intend to distribute the Registrable
         Securities covered by their request by means of an underwriting, they
         shall so advise NPDC as a part of their request made pursuant to
         Section 2.3 and NPDC shall include such information in its written
         notice to the Holders referred to in Section 2.3(a). In such event, the
         right of any Holder to include its Registrable Securities in such
         registration shall be conditioned upon such Holder's participation in
         such underwriting and the inclusion of such Holder's Registrable
         Securities in the underwriting to the extent provided herein. All
         Holders proposing to distribute their securities through such
         underwriting shall enter into an underwriting agreement in customary
         form with the underwriter or underwriters selected for such
         underwriting by NPDC and approved by Holders of a majority of the
         Registrable Securities to be included in such underwriting.
         Notwithstanding any other provision of this Section 2.3 to the
         contrary, if the underwriter advises NPDC that marketing factors
         require a limitation of the number of securities to be underwritten
         (including Registrable Securities) then NPDC shall so advise all
         Holders of Registrable Securities electing to participate in the
         registration under this Section 2.3, and the number of shares that may
         be included in the underwriting shall be allocated to the Holders of
         such Registrable Securities on a pro rata basis based on the number of
         Registrable Securities held by all such electing Holders (including the
         Initiating Holders). If any Holder disapproves of the terms of any such
         underwriting, such Holder may elect to withdraw therefrom by written
         notice to NPDC and the underwriter, delivered at least 10 business days
         prior to the effective date of the registration statement. Any
         Registrable Securities excluded or withdrawn from such underwriting
         shall be excluded and withdrawn from the registration.

2.4      Piggyback Registrations.

(a) NPDC shall notify all Holders at least 30 days prior to the filing of any
registration statement under the Securities Act for a public offering of
securities of NPDC (including, but not limited to, registration statements
relating to secondary offerings of securities of NPDC, but excluding
registration statements relating to employee benefit plans or corporate
reorganizations or other transactions under Rule 145 of the Securities Act) and





will afford each such Holder an opportunity to include in such registration
statement all or part of the Registrable Securities held by such Holder;
provided, that no such notice shall be required, and this Section 2.4 shall not
be applicable, at any time when the registration statement filed under Section
2.2 is effective. Such notice shall (i) offer each Holder the opportunity to
register such number of Registrable Securities as it may request and (ii)
describe such securities and specify the form and manner and other relevant
facts involved in such proposed registration (including, without limitation, if
known, the price at which such securities are reasonably expected to be sold to
the public, whether or not such registration will be in connection with an
underwritten offering and, if so, the identity of the managing underwriter,
whether such underwritten offering will be pursuant to a "best efforts" or "firm
commitment" underwriting, and, if known, the amount of underwriting discount
reasonably expected to be incurred in connection therewith). Each Holder
desiring to include in any such registration statement all or part of the
Registrable Securities held by it shall, within 15 days after receipt of the
above-described notice from NPDC, so notify NPDC in writing. Such notice shall
state the number of Registrable Securities which such Holder requests to be
included in such registration and the intended method of disposition of the
Registrable Securities by such Holder. If a Holder decides not to include all of
its Registrable Securities in any registration statement thereafter filed by
NPDC, such Holder shall nevertheless continue to have the right to include any
Registrable Securities in any subsequent registration statement or registration
statements as may be filed by NPDC, all upon the terms and conditions set forth
herein.

(b) If the registration statement under which NPDC gives notice under this
Section 2.4 is for an underwritten offering, the right of any Holder to be
included in a registration pursuant to this Section 2.4 shall be conditioned
upon the Holder's participation in the underwriting and the inclusion of such
Holder's Registrable Securities in the underwriting to the extent provided
herein. All Holders proposing to distribute their Registrable Securities through
such underwriting shall enter into an underwriting agreement in customary form
with the underwriter or underwriters selected for such underwriting by NPDC.
Notwithstanding any other provision of this Section 2.4, if the underwriter
determines in good faith that marketing factors require a limitation of the
number of securities to be underwritten (including Registrable Securities), then
NPDC shall so advise all participating Holders, and the number of securities
that may be included in the underwriting shall be allocated first, to NPDC;
second, to the participating Holders and to any other stockholders of NPDC
having comparable rights, on a pro rata basis based on the total number of
Registrable Securities requested to be sold by all such Holders and such other
stockholders; and third, to any other stockholders of NPDC (other than Holders
and any other stockholders of NPDC having comparable rights) on a pro rata
basis. If any Holder disapproves of the terms of any such underwriting, such
Holder may elect to withdraw therefrom by written notice to NPDC and the
underwriter, delivered at least 10 business days prior to the effective date of
the registration statement. Any Registrable Securities excluded or withdrawn
from such underwriting shall be excluded and withdrawn from the registration.

(c) NPDC shall have the right to terminate or withdraw any registration
initiated by it under this Section 2.4 prior to the effectiveness of such
registration whether or not any Holder has elected to include securities in such
registration. The Registration Expenses of such withdrawn registration shall be
borne by NPDC in accordance with Section 2.6.






2.5 Suspension of Registration. Under any registration statement filed pursuant
to Section 2 hereof, NPDC may restrict disposition of Registrable Securities,
and Holders will not be able to dispose of such Registrable Securities, if NPDC
shall have delivered a certificate signed by an officer of NPDC stating that in
the good faith judgment of the Board of Directors of NPDC a delay in the
disposition of such Registrable Securities is necessary because NPDC has
determined that such sales would require public disclosure by NPDC of material
nonpublic information that is not included in such registration statement. In
the event of the delivery of such certificate, NPDC shall use its best efforts
to amend such registration statement or amend or supplement the related
prospectus as necessary, and take all other actions necessary, to allow the
proposed sale to take place as promptly as possible (or, if in the reasonable
judgment of the Board of Directors of NPDC disclosure of such event would be
detrimental to NPDC, promptly after the earlier of (a) the date that disclosure
of such event would not be detrimental to NPDC and (b) 90 days after the date of
such certificate, provided, however, that such right to delay the sales of
Registrable Securities may be exercised by NPDC not more than once in any
12-month period and that, in each such case, the delay in the sale of the
Registrable Securities included in the registration statement shall not exceed
120 days from the date of the certificate).

2.6 Expenses of Registration. Except as specifically provided herein, all
Registration Expenses incurred in connection with any registration pursuant to
Section 2.2, 2.3, or 2.4 shall be borne by NPDC. All Selling Expenses incurred
in connection with any registrations hereunder shall be borne by the holders of
the securities so registered pro rata on the basis of the number of shares so
registered. NPDC shall not, however, be required to pay for expenses of (a) any
registration begun pursuant to Section 2.3, the request for which has been
subsequently withdrawn by the Holders, unless (i) the withdrawal is based upon
material adverse information concerning NPDC of which the Holders were not aware
at the time of such request or (ii) the Initiating Holders agree to forfeit one
of their requested registrations under Section 2.3, in which event such right
shall be forfeited by all Holders, or (b) more than one registration initiated
under Section 2.3 (other than any such registration the request for which is
withdrawn as described in Section 2.6(a)(i)). If NPDC is not required to pay the
Registration Expenses, such expenses shall be borne by the Holders requesting
such registration in proportion to the number of shares for which registration
was requested; and, if NPDC has previously paid any such expenses, such Holders
shall promptly reimburse NPDC therefore.

2.7 Obligations of NPDC.  Whenever required to register any Registrable
Securities, NPDC shall, as expeditiously as reasonably possible:

(a) Prepare and file with the SEC a registration statement with respect to such
Registrable Securities and use its best efforts to cause such registration
statement to become effective.

(b) Use its best efforts to keep such registration statement effective (i) in
the case of a registration statement filed under Section 2.2, until the earliest
to occur of (A) the date on which all Registrable Securities have been sold
pursuant to such registration statement or Rule 144 and (B) the date on which no
Registrable Securities remain outstanding, and (ii) in the case of a





registration statement under Section 2.3 or 2.4, for up to 90 days (or three
years if the registration statement is on Form S-3), as requested by the Holders
of a majority of the Registrable Securities registered thereunder, or, if
earlier, until the Holder or Holders have completed the distribution related
thereto.

(c) Prepare and file with the SEC such amendments (including post effective
amendments and supplemental opinions of counsel, if required) and supplements to
such registration statement and the prospectus used in connection with such
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 such
registration statement for the period set forth in Section 2.7(b).

(d) 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 documents as they may reasonably request to facilitate the
disposition of Registrable Securities owned by them.

(e) Use its best efforts to register and qualify the Registrable Securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders, and
do any and all other acts and things which may be reasonably necessary or
advisable to enable such Holders to consummate the disposition of the
Registrable Securities owned by such Holder in such jurisdictions; provided that
NPDC 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.

(f) Use its best efforts to cause the Registrable Securities covered by such
registration statement to be registered or qualified with or approved by such
other governmental agencies or authorities (including, without limitation, state
securities commissions) as may be necessary to enable the Holder or Holders
thereof to consummate the disposition of such Registrable Securities.

(g) Notify each Holder, promptly after NPDC shall receive notice thereof, of the
date and time the registration statement and each post-effective amendment
thereto has become effective or a supplement to any prospectus forming a part of
such registration statement has been filed.

(h) Notify each Holder of Registrable Securities covered by such 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 such 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 the light of the circumstances then existing, and, at the
request of any such Holder, subject to Section 2.5, deliver a reasonable number
of copies of an amended or supplemental 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 then
existing.






(i) Within a reasonable time before each filing of the registration statement or
any amendment or supplement thereto with the SEC, furnish to one counsel,
selected by the Holders of a Majority of the Registrable Securities included
therein, copies of such documents proposed to be filed, which documents shall be
subject to the reasonable approval of such counsel.

(j) Use its best efforts to prevent the issuance of any order suspending the
effectiveness of a registration statement and, if one is issued, immediately
notify each selling Holder of the receipt of such notice and use its best
efforts to obtain the withdrawal of any order suspending the effectiveness of a
registration statement at the earliest possible moment.

(k) Make available to each selling Holder and any attorney, accountant, or other
agent or representative retained by any such selling Holder or underwriter
(collectively, the "Inspectors"), all financial and other records, pertinent
corporate documents, and properties of NPDC, as shall be reasonably necessary to
enable them to exercise their due diligence responsibility, and cause NPDC's
officers, directors, and employees to supply all information requested by any
such Inspector in connection with such registration statement, subject, in each
case, to such confidentiality agreements as NPDC shall reasonably request.

(l) Use its best efforts to cause the securities covered by such registration
statement to be listed on any securities exchange or quoted on any quotation
system on which similar securities issued by NPDC are then listed or quoted.

(m) Otherwise use its best efforts to cooperate with the SEC and other
regulatory agencies and take all reasonable actions and execute and deliver or
cause to be executed and delivered all documents reasonably necessary to effect
the registration of any securities under this Agreement.

(n) Provide a transfer agent and registrar for all such Registrable Securities
not later than the effective date of such registration statement.

(o) If such registration involves an underwritten offering, obtain and furnish a
comfort letter, dated the effective date of such registration statement, and the
date of the closing under the underwriting agreement, signed by NPDC's
independent public accountants and addressed to the Holders, in customary form
and covering such matters as are customarily covered by comfort letters by
independent public accountants in such public offerings and such other financial
matters as the holders of a majority of the Registrable Securities being sold in
such registration may reasonably request.

(p) If such registration involves an underwritten offering, furnish a legal
opinion of NPDC's counsel, dated the date of the closing under the underwriting
agreement and addressed to the Holders, with respect to the registration
statement, each amendment and supplement thereto, the prospectus included
therein (including the preliminary prospectus) and other documents relating
thereto, in customary form and covering such matters as are customarily covered
by legal opinions of issuers' counsel in such public offerings.






(q) During the period when a prospectus is required to be delivered under the
Securities Act, promptly file all documents required to be filed with the SEC
pursuant to Sections 13(a), 13(c), 14, or 15(d) of the Exchange Act.

2.8 Termination of Registration Rights. A Holder's registration rights shall
expire if all Registrable Securities held by and issuable to such Holder may be
sold under SEC Rule 144 during any 90 day period.

2.9 Furnishing Information. It shall be a condition precedent to the obligations
of NPDC to take any action pursuant to Section 2.2, 2.3, or 2.4 that the selling
Holders shall furnish to NPDC such information regarding themselves, the
Registrable Securities held by them, and the intended method of disposition of
such securities as shall be required to effect the registration of their
Registrable Securities.

2.10 Indemnification. If any Registrable Securities are included in a
registration statement under Section 2.2, 2.3, or 2.4:

(a) To the extent permitted by law, NPDC will indemnify and hold harmless each
Holder and the partners, members, officers, directors, trustees, stockholders,
employees, and agents of each Holder, any underwriter (as defined in the
Securities Act) for such Holder, and each person, if any, who controls such
Holder or underwriter within the meaning of the Securities Act or the Exchange
Act, against any losses, claims, damages, or liabilities (joint or several) to
which 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 NPDC: (i) any untrue statement or alleged untrue statement of a
material fact contained in such 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 NPDC of
the Securities Act, the Exchange Act, or 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 such registration
statement; and NPDC will pay as incurred to each such Holder, partner, member,
officer, director, trustee, stockholder, employee, agent, underwriter, or
controlling person any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability, or action; provided however, that the indemnity agreement contained
in this Section 2.10(a) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability, or action if such settlement is effected
without the consent of NPDC, which consent shall not be unreasonably withheld,
nor shall NPDC 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 a
Violation which occurs in reliance upon and in conformity with written
information furnished expressly for use in connection with such registration by
such Holder, partner, member, officer, director, trustee, stockholder, employee,
agent, underwriter, or controlling person. With respect to any untrue statement
or alleged untrue statement made in, or omission or alleged omission from, any
preliminary prospectus, any Rule 430A prospectus, or any prospectus, the
indemnity agreement contained in this Section 2.10(a) with respect to such
preliminary prospectus, Rule 430A prospectus, or prospectus, to the extent it is
based on the claim of a person who purchased securities directly from a person,





shall not inure to the benefit of such person (or to the benefit of any of its
partners, members, officers, directors, trustees, stockholders, employees,
agents, or counsel, or any person controlling such person ) if the prospectus
(or the prospectus as amended or supplemented if NPDC shall have filed with the
SEC any amendment or supplement thereto) which shall have been furnished to such
person prior to the time it sent written confirmation of or otherwise confirmed
such sale to such purchaser does not contain such statement, alleged statement,
omission, or alleged omission and a copy of the prospectus (or the prospectus as
amended or supplemented if NPDC shall have filed with the SEC any amendment or
supplement thereto) shall not have been sent or given to such purchaser and such
purchaser shall not otherwise have received a copy thereof at or prior to the
written confirmation of such sale.

(b) To the extent permitted by law, each Holder will, if Registrable Securities
held by such Holder are included in the securities as to which such registration
is being effected, indemnify and hold harmless NPDC, each of its directors, its
officers, and each person, if any, who controls NPDC within the meaning of the
Securities Act, any underwriter, and any other Holder selling securities under
such registration statement or any of such other Holder's partners, members,
officers, directors, trustees, stockholders, employees, agents, or any person
who controls such Holder, against any losses, claims, damages, or liabilities
(joint or several) to which NPDC or any such person 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 (and only to
the extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by such Holder specifically for use in connection
with such registration; and each such Holder will pay as incurred any legal or
other expenses reasonably incurred by NPDC or any such person in connection with
investigating or defending any such loss, claim, damage, liability, or action if
it is judicially determined that there was such a Violation; provided, however,
that the indemnity agreement contained in this Section 2.10(b) shall not apply
to amounts paid in settlement of any such loss, claim, damage, liability, or
action if such settlement is effected without the consent of the Holder, which
consent shall not be unreasonably withheld; provided further, that in no event
shall any indemnity obligation of any Holder under this Section 2.10 exceed the
net proceeds received by such Holder from the sale of Registrable Securities
pursuant to such registration statement.

(c) Promptly after receipt by an indemnified party under this Section 2.10 of
notice of the commencement of any action (including any governmental action),
such indemnified party will, if a claim in respect thereof is to be made against
any indemnifying party under this Section 2.10, 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,
to assume the defense thereof with counsel mutually satisfactory to the parties;
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. 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 any liability to the indemnified party under
this Section 2.10, but the omission so to 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 2.10.

(d) If the indemnification provided for in this Section 2.10 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
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 the indemnifying party or by
the indemnified party and the parties' relative intent, knowledge, access to
information, and opportunity to correct or prevent such statement or omission;
provided, that in no event shall any contribution by a Holder hereunder exceed
the net proceeds from the offering received by such Holder. The parties hereto
agree that it would not be just and equitable if contribution pursuant to this
Section 2.10 were determined by pro rata allocation or any other method of
allocation which does not take into account the equitable consideration referred
to in this Section 2.10(d).

(e) The obligations of NPDC and the Holders under this Section 2.10 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
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.

2.11 Assignment of Registration Rights. A Holder may assign such Holder's rights
under this Agreement, including, without limitation, its rights to cause NPDC to
register Registrable Securities pursuant to this Section 2, to any person to
whom (a) prior to the Spin-Off Date, GP Warrants are transferred, or (b) after
the Spin-Off Date, NPDC Warrants or Registrable Securities are transferred, in
either case, in compliance with the restrictions of this Agreement, the GP
Warrants or the NPDC Warrants, as the case may be, and the Purchase Agreement,
provided that (i) in the case of a transfer of Registrable Securities, such
transferee (A) is a subsidiary, parent, general partner, limited partner,
member, or affiliate of such Holder or an investment company registered under
the Investment Company Act of 1940, as amended, advised by Gebelli Fund, LLC or
(B) acquires a number of shares of Registrable Securities at least equal to
one-fifteenth of the number of NPDC Warrants originally issued (as adjusted for
stock splits, stock dividends, combinations, reorganizations, reclassifications,
and other similar events), (ii) the transferor, within ten days after such





transfer, furnishes to NPDC written notice of the name and address of such
transferee or assignee and the securities with respect to which such
registration rights are being assigned, and (iii) such transferee agrees in
writing to be subject to all restrictions set forth in this Agreement.

2.12 Rule 144. With a view to making available to the Holders the benefits of
certain rules and regulations of the SEC which may permit the sale of the
Registrable Securities to the public without registration, NPDC agrees to use
its best efforts to, at all times at which any Registrable Securities are
eligible for sale under Rule 144 (other than paragraph (k) thereof):

(a)      make and keep public information available, as those terms are
         understood and defined in 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 NPDC under the Exchange Act;

(c)      furnish to each Holder, forthwith upon request, a written statement by
         NPDC as to its compliance with the reporting requirements of Rule 144
         and of the Exchange Act, a copy of the most recent annual or quarterly
         report of NPDC, and such other reports and documents as such Holder may
         reasonably request to sell Registrable Securities under Rule 144; and

(d)      cooperate with each Holder in good faith to enable such Holder to
         deliver, promptly upon any sale of Registrable Securities (or
         securities which, in the absence of eligibility for sale under Rule
         144, would be Registrable Securities) by such Holder under Rule 144
         under the Securities Act, certificates representing such securities
         which shall not contain any restrictive legend.

Section 3.        Miscellaneous.

3.1 Governing Law; Jurisdiction.  This Agreement shall be governed by and
construed in accordance with the laws of the State of New York, without giving
effect to conflict of laws.

3.2 Successors and Assigns. Except as otherwise expressly provided herein, the
provisions hereof shall inure to the benefit of, and be binding upon, the
permitted successors, assigns, heirs, executors, and administrators of the
parties hereto; provided, however, that prior to the receipt by NPDC of adequate
written notice of the transfer of any Registrable Securities specifying the full
name and address of the transferee, NPDC may deem and treat the person listed as
the holder of such securities in its records as the absolute owner and holder of
such securities for all purposes.

3.3 Entire Agreement. This Agreement, the NPDC Warrants, the Purchase Agreement,
and the other documents delivered pursuant thereto set forth the entire
understanding of the parties with respect to the subject matter hereof and
supersede all existing agreements among them concerning such subject matter.






3.4 Severability. If any provision of this Agreement is invalid, illegal, or
unenforceable, the balance of this Agreement shall remain in effect, and if any
provision is inapplicable to any person or circumstance, it shall nevertheless
remain applicable to all other persons and circumstances.

Agent with the written consent of Majority Holders. Any amendment or waiver
effected in accordance with this Section 3.5 shall be binding upon each Holder
and NPDC.

(b) Any waiver of a breach of any provision of this Agreement shall not operate
as or be construed to be a waiver of any other breach of such provision or of
any breach of any other provision of this Agreement. The failure of a party to
insist upon strict adherence to any term of this Agreement on one or more
occasions shall not be considered a waiver or deprive that party of the right
thereafter to insist upon strict adherence to that term or any other term of
this Agreement. Any waiver must be in writing.

permitted to be given hereunder shall be in writing and shall be given by
