         Agreement, dated August 8, 2003, among GP Strategies Corporation, a
Delaware corporation ("GP"), National Patent Development Corporation, a Delaware
corporation ("NPDC"), MXL Industries, Inc., a Delaware corporation ("MXL"), the
purchasers set forth on the signature pages hereto (the "Purchasers"), and
Gabelli Funds, LLC, as agent ("Agent").

         The Purchasers desire to acquire the Notes, the GP Warrants, and, upon
the completion of the Spin-Off of NPDC by GP, the NPDC Warrants (each as defined
below), in exchange for cash as hereinafter provided, and GP and NPDC desire to
effect such exchange.

         Certain capitalized terms used in this Agreement are defined in Article
XIII; references to a "Schedule" or an "Exhibit" are, unless otherwise
specified, to a Schedule or an Exhibit attached to this Agreement.

I.       The Exchange

1.1.     Authorization of Notes and GP Warrants.

(a)      GP has authorized the issue and sale of $7,500,000 aggregate principal
         amount of its 6% Conditional Subordinated Notes due 2008. Such 6%
         Conditional Subordinated Notes due 2008 shall be substantially in the
         form set forth in Exhibit A and are herein referred to individually as
         a "Note" and collectively as the "Notes," which terms shall also
         include any notes delivered in exchange or replacement therefor.

(b)      GP has also authorized the issue and sale of 937,500 warrants, each
         entitling the holder thereof to purchase (subject to adjustment as
         provided therein) one share ("GP Warrant Shares") of GP Common Stock.
         Such warrants shall be evidenced by warrant certificates substantially
         in the form set forth in Exhibit B ("GP Warrant Certificates," which
         term shall also include any warrant certificates delivered in exchange
         or replacement therefor) and are herein referred to individually as a
         "GP Warrant" and collectively as the "GP Warrants."

(c)      NPDC has authorized the issue of up to the NPDC Warrant Amount of
         warrants, each entitling the holder thereof to purchase (subject to
         adjustment as provided therein) one share ("NPDC Warrant Shares") of
         NPDC Common Stock. Such warrants shall be evidenced by warrant
         certificates in the form set forth in Exhibit C ("NPDC Warrant
         Certificates," which term shall also include any warrant certificates
         delivered in exchange or replacement therefor) and are herein referred
         to individually as an "NPDC Warrant" and collectively as the "NPDC
         Warrants."

1.2.     Terms of the Exchange. On the basis of the representations, warranties,

         the Purchasers will purchase from GP, (a) a Note in the principal
         amount specified opposite such Purchaser's name in Schedule 1.2 and (b)
         a number of GP Warrants specified opposite such Purchaser's name in



         Schedule 1.2, at a purchase price for such Note and GP Warrants
         collectively equal to 100% of the principal amount of such Note. The
         obligations of each Purchaser hereunder are several and not joint
         obligations and no Purchaser shall have any obligation or liability to
         any person for the performance or non-performance by any other
         Purchaser hereunder.

1.3.     Closing.

(a)      The closing of the transactions contemplated by Section 1.2 (the
         "Closing") shall take place at the offices of Duane Morris LLP, 380
         Lexington Avenue, New York, New York, at 10:00 a.m. local time on the
         second Business Day after the condition in Section 2.14 has been
         satisfied (the "Closing Date"). The Closing may occur at such different
         place, different time, or different date as GP, NPDC, the Purchasers,
         and the Agent agree in writing.

(b)      At the Closing, GP shall deliver to each Purchaser, against delivery by
         such Purchaser to GP or its order, by wire transfer of immediately
         available funds, of payment of the full purchase price for the Note and
         GP Warrants to be purchased by such Purchaser:

(i)      a Note in the principal amount to be purchased by such Purchaser, dated
         the Closing Date, and registered in the name of such Purchaser; and

         by such Purchaser, dated the Closing Date, and registered in the name

warranties, covenants, and agreements contained in this Agreement and subject to
the  terms  and  conditions  of  this  Agreement,  and in  consideration  of the

Spin-Off, NPDC,



effective as of the  Spin-Off  Date,  will issue,  to each holder (a "GP Warrant
Holder") of record of GP Warrants outstanding on the NPDC Warrant Record Date, a
number of NPDC  Warrants  equal to the greatest  whole  number of NPDC  Warrants
equal to or less than the NPDC  Warrant  Amount  multiplied  by a fraction,  the
numerator of which is the number of GP Warrants  held by such GP Warrant  Holder
on the NPDC Warrant Record Date and the  denominator of which is 937,500.  On or
as soon as  practicable  after the Spin-Off  Date but in no event later than the

IV. Representations and Warranties of GP

     GP represents and warrants to the Purchasers as follows:

     4.1.  Organization and  Qualification.  GP is a corporation duly organized,
validly existing,  and in good standing under the laws of the State of Delaware,
with all  requisite  power and  authority to own,  lease,  license,  and use its
properties and assets and to carry on the business in which it is engaged. GP is
duly  qualified  to transact  the business in which it is engaged and is in good
standing as a foreign  corporation in every jurisdiction in which its ownership,
leasing,  licensing, or use of property or assets or the conduct of its business



makes such qualification necessary,  except as would not be reasonably likely to
have a Material Adverse Effect on GP.

     4.2.  SEC Reports.  GP has  delivered  to the  Purchasers  true and correct
copies of its Annual  Report on Form 10-K for the year ended  December  31, 2002
(the "Form 10-K"), Quarterly Report on Form 10-Q for the quarter ended March 31,
2003, all Current Reports on Form 8-K filed with the SEC since the filing of the
Form 10-K, and its Proxy Statement dated June 10, 2002  (collectively,  the "SEC
Reports").  None of the SEC Reports when filed with the SEC  contained an untrue
statement of a material  fact or omitted to state a material fact required to be
stated therein or necessary to make the statements  made therein not misleading.
From the date of the last SEC Report to the Closing  Date, no event has occurred
which  individually  or in the  aggregate,  has,  had,  or could  reasonably  be
expected to have a Material Adverse Effect on GP.

     4.3.  Capitalization.  The  authorized  capital  stock  of GP  consists  of
25,000,000  shares of GP Common Stock and 2,800,000  shares of GP Class B Stock,
of which as of the date of this Agreement  16,159,702  shares of GP Common Stock
and  1,200,000  shares  of GP  Class  B  Stock  are  outstanding.  Each  of such
outstanding  shares  of GP  Common  Stock  and  GP  Class  B  Stock  is  validly
authorized,  validly  issued,  fully paid, and  nonassessable,  and has not been
issued  and is not  owned  or held  in  violation  of any  preemptive  right  of
stockholders.  Other  than as  contemplated  by  this  Agreement  and the  other
Transaction  Documents  and  as  disclosed  in  the  SEC  Reports,  there  is no
commitment,  plan, or arrangement to issue, and no outstanding option,  warrant,
or other right  calling for the issuance of, any share of capital stock of GP or
any  security  or  other  instrument   convertible  into,  exercisable  for,  or
exchangeable  for  capital  stock  of GP.  Other  than as  disclosed  in the SEC
Reports,  there is outstanding no security or other instrument  convertible into
or exchangeable for capital stock of GP.

     4.4. Litigation and Claims.  Except as disclosed in the SEC Reports,  there
is no litigation,  arbitration,  claim, governmental or other proceeding (formal
or informal),  or investigation  pending or, to the knowledge of GP, threatened,
with respect to GP or any GP Subsidiary (as defined below) which has, had, or is
reasonably likely to have a Material Adverse Effect on GP.

     4.5.  Authority  to  Sell;  Enforceability;  Valid  Issuance.  GP  has  all
requisite  power and authority to execute,  deliver,  and perform this Agreement
and the other Transaction Documents to be executed,  delivered, and performed by
it. All necessary corporate  proceedings of GP have been duly taken to authorize
the execution,  delivery,  and performance by GP of this Agreement and the other
Transaction  Documents to be executed,  delivered,  and performed by it. Each of
this Agreement and the other  Transaction  Documents to be executed,  delivered,
and performed by GP has been duly  authorized by GP and this Agreement has been,
and at the Closing the other  Transaction  Documents to be executed,  delivered,
and  performed by GP will be, duly  executed  and  delivered by GP. Each of this
Agreement and the other  Transaction  Documents to be executed,  delivered,  and
performed by GP constitutes or will  constitute  the legal,  valid,  and binding
obligation of GP and is or will be enforceable  as to GP in accordance  with its
terms, except (a) as limited by applicable  bankruptcy,  insolvency,  fraudulent



conveyance,  reorganization,  moratorium,  or other laws of general  application
affecting enforcement of creditors' rights, (b) for general principles of equity
that restrict the availability of equitable remedies, and (c) to the extent that
the enforceability of the  indemnification  provisions of Section 2.10 of the GP
Registration  Rights Agreement may be limited by applicable laws. All GP Warrant
Shares  have been  reserved  for  issuance  and,  when issued and  delivered  on
exercise of the GP  Warrants  and payment  therefor  in  accordance  with the GP
Warrants or in accordance with the Notes,  will be validly  authorized,  validly
issued, fully paid, and nonassessable and will not have been issued in violation
of any  preemptive  right  of  stockholders.  Each  Purchaser  or  other  Person
receiving  GP Warrant  Shares upon  exercise of GP Warrants in  accordance  with
their terms will receive good title to such shares, free and clear of all liens,
security interests,  pledges, charges,  encumbrances,  stockholders' agreements,
and voting trusts, other than (x) those imposed by the Purchaser or other Person
receiving the same, (y)  restrictions  on transfer under  applicable  securities
laws, and (z) as provided in the GP Warrant Certificate or Note, as applicable.

     4.6. No Conflicts.  No consent,  authorization,  approval,  order, license,
certificate,  or permit of or from, or  declaration or filing with, any federal,
state, local, or other governmental  authority or any court or other tribunal is
required  by GP for  the  execution,  delivery,  or  performance  by GP of  this
Agreement or the other  Transaction  Documents to be  executed,  delivered,  and
performed by GP, except for the filing of a Form D under the  Securities Act and
as may be required under state  securities  laws. No consent of any party to any
contract, agreement,  instrument, lease, or license (collectively,  "Contracts")
to  which  GP or any GP  Subsidiary  is a  party,  or to  which it or any of its
businesses,  properties,  or assets are subject,  is required for the execution,
delivery, or performance of this Agreement or the other Transaction Documents to
be executed,  delivered, and performed by GP, other than the consent and release
of the Banks as referred to in Section  3.5;  and, if such  consent is obtained,
the execution,  delivery,  and performance by GP of this Agreement and the other
Transaction  Documents to be executed,  delivered,  and performed by GP will not
violate, result in a breach of, conflict with, or (with or without the giving of
notice or the passage of time or both)  entitle any party to terminate or call a
default under,  entitle any party to rights and  privileges  that such party was
not  receiving  or entitled to receive  immediately  before this  Agreement  was
executed  under, or create any obligation on the part of GP or any GP Subsidiary
that it was not paying or obligated to pay immediately before this Agreement was
executed under, any term of any such Contract,  or result in the creation of any
lien (except as set forth in the Mortgage) on any of GP's or any GP Subsidiary's
properties  or  assets,  or  violate  or  result  in a breach of any term of the
certificate of incorporation (or other charter document) or by-laws of GP or any
GP  Subsidiary,  or violate,  result in a breach of, or  conflict  with any law,
rule, regulation,  order, judgment, or decree binding on GP or any GP Subsidiary
or to which it or any of its businesses,  properties,  or assets are subject, in
each case except as would not be  reasonably  likely to have a Material  Adverse
Effect on GP.

4.7. No Registration Required. Assuming the continuing accuracy of the
representations and warranties of the Purchasers contained in Article VII
hereof, the offer, sale and issuance of (a) the Notes, (b) the GP Warrants, and



(c) upon exercise of the GP Warrants in accordance with their terms, the GP
Warrant Shares will be exempt from the registration requirements of the
Securities Act.

     4.8. No Event of Default.  There exists no event of default under the terms
and  provisions  of any  instrument,  agreement,  or contract  pertaining to any
indebtedness of GP, including Senior  Indebtedness (as defined in the Note), and
to GP's knowledge there exists no event or condition  which,  with due notice or
lapse of time or both, would constitute such an event of default.

     4.9. Title to Premises. GP has on the date hereof, and, if the Contemplated
Conveyance has not taken place, will have at the Closing, an indefeasible estate
in fee simple in the portion of the Premises which constitutes real property and
GP owns on the date hereof,  and, if the  Contemplated  Conveyance has not taken
place, will own at the Closing,  good title to the portion of the Premises which
constitutes personal property, in each case and to GP's knowledge,  subject only
to the  encumbrances  set forth on  Schedule  2.15,  the  Existing  Lien,  liens
securing the Notes,  and such other matters as may be approved in writing by the
Purchasers. No person has asserted a claim against GP or, to GP's knowledge, has
threatened  to assert a claim  against GP or the  Premises  that would,  if such
claim were  upheld,  result in an  encumbrance  to the  Premises  (other than an
encumbrance  set forth on Schedule 2.15,  the Existing Lien,  liens securing the
Notes,  or such other  matters as may be approved in writing by the  Purchasers)
which would  materially  adversely  affect the value,  use or  enjoyment  of the
Premises, and there are no facts known to GP that would allow such a claim to be
successfully asserted. Subject to obtaining the consent and release of the Banks
as  referred  to in Section  3.5,  (a) GP has on the date  hereof,  and,  if the
Contemplated  Conveyance  has not taken place,  will have at the  Closing,  good
right,  full power, and lawful authority to convey and mortgage to the Agent and
grant to the Agent a security  interest in the same,  in the manner and form set
forth in the Mortgage; (b) subject to the Permitted Encumbrances and other Liens
(as such terms are defined in the Mortgage)  permitted pursuant to the Mortgage,
the Mortgage  will,  at the time of its delivery to Agent,  and  thereafter be a
valid and enforceable  and, upon  recordation,  perfected first mortgage lien on
the Premises;  and (c) GP shall and will warrant and forever defend the title to
the Premises unto Agent against the claims of all Persons whomsoever.

     4.10. Environmental Matters. To the knowledge of GP, except as set forth in
the Environmental  Report,  (a) there are no Hazardous  Materials or underground
storage tanks in, on, or under the  Premises,  except those that are both (i) in
compliance with  Environmental Laws and with permits issued pursuant thereto (if
such  permits are  required),  if any, and (ii) in amounts not in excess of that
necessary to operate the Premises; (b) there are no past, present, or threatened
Releases of Hazardous  Materials in violation of any Environmental Law and which
would require remediation by a governmental authority in, on, under, or from the
Premises; (c) there is no threat of any Release of Hazardous Materials migrating
to  the  Premises  ;  (d)  there  is no  past  or  present  non-compliance  with
Environmental  Laws, or with permits issued pursuant thereto, in connection with
the Premises; (e) GP does not know of, and has not received, any written or oral
notice or other  communication  from any Person  (including but not limited to a
governmental  entity) relating to Hazardous Materials in, on, under, or from the
Premises;  and (f) GP has truthfully and fully  provided to the  Purchasers,  in



writing,  any and all information  relating to environmental  conditions in, on,
under,  or from the Premises known to GP or contained in GP's files and records,
including but not limited to any reports relating to Hazardous Materials in, on,
under,  or  migrating  to or  from  the  Premises  and/or  to the  environmental
condition of the Premises.

     4.11. GP Taxes.  GP has filed all federal,  state,  local,  and foreign tax
returns,  informational  returns,  and excise tax returns  which are required to
have been filed by it,  and there  have been paid all taxes  shown to be due and
payable on such returns and all other material taxes and assessments  payable by
it,  unless any such tax or  assessment  is being  diligently  contested in good
faith and GP has adequately reserved against such tax or assessment on its books
and financial  statements in accordance  with GAAP, in each case except as would
not be reasonably  likely to have a Material  Adverse  Effect on GP. No material
tax liens have been filed and no material claims are being asserted with respect
to any such taxes as of the date hereof.  No material tax assessment  against GP
has been proposed and all of its tax liabilities are adequately  provided for on
its books and financial statements in accordance with GAAP.

     4.12.  Broker's  or  Finder's  Commissions;  Financial  Advisory  Fees.  No
broker's or finder's fee or  commission  or  financial  advisory or similar fees
will be payable by GP or any of its affiliates  with respect to the issuance and
sale of the  Notes,  the GP  Warrants,  or the NPDC  Warrants  or  otherwise  in
connection with the transactions contemplated by the Transaction Documents.

     4.13.  Solvency.  GP is and shall be Solvent  both before and after  giving
effect  to the  transactions  contemplated  by  this  Agreement  and  the  other
Transaction Documents to be effected on or prior to the Closing Date.

     4.14. Permits. GP has all franchises,  permits,  licenses,  and any similar
authority  necessary  for the conduct of its business as now being  conducted by
it, the lack of which,  individually  or in the  aggregate,  has,  had, or could
reasonably be expected to have a Material Adverse Effect on GP.

     4.15. Subsidiaries.  The only subsidiaries of GP which are significant,  as
defined in Regulation S-X promulgated by the SEC, are those subsidiaries  listed
on Schedule 4.15 (the "GP Subsidiaries").

     4.16. Disclosure.  None of the factual information concerning GP and the GP
Subsidiaries  set  forth  in the  SEC  Reports  or  delivered  pursuant  to this
Agreement,  the other Transaction Documents, or the other documents set forth on
Schedule  4.16  contains as of its date,  certification,  or delivery any untrue
statement  of a material  fact,  and all such  factual  information  (taken as a
whole) does not omit to state a material fact  required to be stated  therein or
necessary to make the statements  therein,  in light of the circumstances  under
which they are made, not misleading.

relating to any such actual or alleged broker's or finder's fee or commission.

VIII. Covenants and Agreements

     The parties covenant and agree as follows:




     8.1.  Advice of  Changes.  Until the  Closing  or the  termination  of this
Agreement, each of GP, NPDC, and MXL will immediately advise the Purchasers in a
detailed  written  notice of any fact or occurrence or any pending or threatened
occurrence  of which any of them  obtains  knowledge  and which (if existing and
known at the date of the execution of this  Agreement)  would have been required
to be set  forth or  disclosed  in or  pursuant  to this  Agreement,  which  (if
existing  and  known at any  time  prior to or at the  Closing)  would  make the
performance by any party of a covenant contained in this Agreement impossible or
make such performance materially more difficult than in the absence of such fact
or occurrence, or which (if existing and known at the time of the Closing) would
cause a condition  to any party's  obligations  under this  Agreement  not to be
fully  satisfied.  Any such  notice  or  disclosure  shall be given no effect in
satisfying any of the conditions of Section 2.1 hereof.

     8.2. Furnish Future Information. After the Closing, GP shall deliver to the
holders of the Notes and the GP  Warrants,  for so long as such  Persons own any
Notes or GP Warrants,  promptly  upon their  becoming  available,  copies of all
financial statements,  reports,  notices, and proxy statements sent by it to its
stockholders,  all regular and periodic  reports filed by it with any securities
exchange or with the SEC, and all material  press  releases.  After the Spin-Off
Date,  NPDC shall  deliver to the holders of the NPDC  Warrants,  for so long as
such Persons own any NPDC  Warrants,  promptly  upon their  becoming  available,

securities exchange or with the SEC, and all material press releases.

     8.3. Mortgage.

     (a) Each Purchaser and other Security Holder  acknowledges and agrees that,
in contemplation of the Spin-Off, GP shall have the right to convey the Premises
to MXL, which at the time of such conveyance  will be a wholly-owned  subsidiary
of  NPDC  (such   conveyance   is  referred  to  herein  as  the   "Contemplated
Conveyance").  GP will give prompt notice to the Agent of the  occurrence of the
Contemplated  Conveyance.  Whether  or not  the  Spin-Off  or  the  Contemplated
Conveyance has occurred,  any extension of, or increase in the principal  amount
of,  interest  rate on, or other  charges on, the Notes or any other  amendment,
extension,  waiver, or modification to the Notes or other Transaction  Documents
which increases the  obligations  secured by the Mortgage must be agreed upon in
writing by each of GP, the Agent, and MXL to be effective.

     (b) In connection with the Contemplated Conveyance,  and subject to Section
39 of the  Mortgage,  MXL  will,  at the  sole  cost of MXL,  (i)  execute  such
documents and take such other actions as may be necessary to assume the Mortgage
and all of the obligations and liabilities of GP arising  thereunder,  provided,
however, that it is expressly understood and agreed that such assumption will be
made subject to the  provisions  of Section 8.4 hereof and (ii) deliver or cause
to be  delivered  an  endorsement  to the Title Policy or a side letter from the
Title  Company (in either case,  provided  that the same is available at nominal
cost),  in form reasonably  acceptable to the Agent,  insuring to the Agent that
(A) MXL is the fee owner of the  Premises  and (B) the  Mortgage,  as assumed by



MXL, is a valid and subsisting  first priority lien against the Premises subject
only to the Permitted Encumbrances.

     (c) Each  Security  Holder which holds any Notes agrees that,  if GP or MXL
shall  tender full  payment of the  outstanding  principal  amount of the Notes,
together with all interest and other sums due  thereunder,  as  contemplated  by
Section 17(a) of the Mortgage,  such Security Holder will promptly  surrender to
the  tenderor and endorse  (without  recourse)  all Notes held by such  Security
Holder as contemplated by such Section 17(a).

     8.4. No Liability.  Each Purchaser and other Security  Holder  acknowledges
and agrees  that,  notwithstanding  anything to the  contrary  contained in this
Agreement  or in any of the other  Transaction  Documents,  except  as  provided
otherwise in this Section 8.4, (a) neither MXL nor any MXL Related  Party (other
than GP) shall have any  personal  liability  for (i) the  payment of any sum of
money  which is or may be  payable  by GP  hereunder  or  under  any  Note,  the
Mortgage,  the GP Warrants, or the GP Registration Rights Agreement,  including,
but not limited  to, the  repayment  of the Notes,  or (ii) the  performance  or
discharge of any  covenants,  obligations,  or  undertakings  of GP hereunder or
under any Note, the Mortgage,  the GP Warrants,  or the GP  Registration  Rights
Agreement,  and no monetary or deficiency  judgment  shall be sought or enforced
against  MXL or any MXL Related  Party  (other  than GP) with  respect  thereto,
notwithstanding  any  conveyance  or  transfer  of  the  Premises  to MXL or any
assumption of the Mortgage by MXL, and (b) neither MXL nor any MXL Related Party
(other than NPDC) shall have any personal  liability  for (i) the payment of any
sum of money  which is or may be  payable  by NPDC  hereunder  or under the NPDC
Warrants or the NPDC Registration  Rights Agreement,  or (ii) the performance or
discharge of any covenants,  obligations,  or  undertakings of NPDC hereunder or
under  the NPDC  Warrants  or the NPDC  Registration  Rights  Agreement,  and no
monetary or deficiency  judgment shall be sought or enforced  against MXL or any
MXL Related Party (other than NPDC) with respect  thereto,  notwithstanding  any
conveyance or transfer of the Premises to MXL or any  assumption of the Mortgage
by MXL; provided,  however, that a judgment may be sought against MXL or any MXL
Related  Party to  enforce  the  rights  of the Agent in,  to,  or  against  the
Premises,  and the Agent  shall have full  recourse  to and the right to proceed
against the Premises. Nothing contained herein shall impair the validity of GP's
obligations  under  the Notes or in any way  affect  or  impair  the lien of the
Mortgage,  or the right of the Agent to enforce any and all rights and  remedies
under and by virtue  of the  Notes,  this  Agreement,  or any other  Transaction
Document,  including, without limitation, naming MXL as a party defendant in any
foreclosure  action,  or limit the Agent from pursuing or seeking to enforce the
rights  of the  Agent  against  any  third  parties,  including  any  guarantor,
indemnitor,  or surety under any guaranty or indemnity  delivered in  connection
with this Agreement,  the Notes, or any other Transaction  Document or otherwise
in connection with the Notes.

     8.5.  Transfer  Restrictions.  Each  Purchaser  and other  Security  Holder
acknowledges  and agrees  that the  Securities  are subject to  restrictions  on
transfer  as set  forth  in the  Notes,  GP  Warrants,  GP  Registration  Rights
Agreement, NPDC Warrants, and NPDC Registration Rights Agreement.




     8.6.  Bank Consent.  GP shall use its  commercially  reasonable  efforts to
obtain  at or  prior to the  Closing  the  Banks'  consent  to the  transactions
contemplated by this Agreement, including the release of the Existing Lien.

     8.7. Title Insurance.  GP shall use its commercially  reasonable efforts to
purchase,  at or prior to the  Closing,  the  Title  Policy in  accordance  with
Section 2.15.

     8.8.  NYSE Listing.  GP shall use its  commercially  reasonable  efforts to
cause The New York Stock Exchange, at or prior to the Closing, to have listed or
approved the listing on official notice of issuance of the GP Warrant Shares.

     8.9. Warrant Purchase. If any party shall terminate this Agreement pursuant
to Section  11.1(e) and the  condition  set forth in Section 2.14 shall not have
been satisfied on or prior to the date notice of  termination is given,  each of
the  Purchasers  shall have the right,  by giving notice to GP not more than ten
days after the date notice of  termination  is given,  to elect to purchase  the
number of GP Warrants  specified opposite such Purchaser's name in Schedule 1.2,
at a  purchase  price  for each  such GP  Warrant  equal to  $4.213,  and not to
purchase the Notes.  Any Purchaser  exercising such right shall also be entitled
to receive NPDC Warrants under the  circumstances and in the manner set forth in
Section 1.4. If any Purchaser exercises such right, the parties agree to modify,
as promptly as practical,  this Agreement  (including,  without limitation,  the
corresponding terms and conditions with respect to closing deliveries, payments,
covenants,  and  indemnities),  the  GP  Warrants,  the  NPDC  Warrants,  the GP
Registration Rights Agreement,  the NPDC Registration Rights Agreement,  and the
Indemnity Agreement to the extent necessary to effectuate such transaction.

     8.10.  Spin-Off.  GP shall  not  consummate  the  Spin-Off  unless,  on the
Spin-Off  Date,  the Agent shall have  received  the opinion of counsel to NPDC,
dated as of such date, substantially in the form set forth in Exhibit J.

     8.11.  Subordination  Agreement.  If any  person  holding or  proposing  to
provide Senior  Indebtedness  so requests,  each Security Holder which holds any
Notes shall (and  authorizes the Agent on such Security  Holder's  behalf to) at
GP's expense enter into a subordination agreement (a "Subordination  Agreement")
contemplated  by Section 7(d) of the Notes,  confirming  and  supplementing  the
provisions  of  Section  7 of  the  Notes,  and  containing  such  terms  as are
customarily  included  in such a  subordination  agreement  and  are  reasonably
satisfactory to the Agent,  in such form as may be reasonably  requested by such
person.  Without limiting the generality of the foregoing,  each Security Holder
which  holds any Notes  shall  (and  authorizes  and  directs  the Agent on such
Security  Holder's  behalf  to) at  GP's  expense  enter  into  a  Subordination
Agreement substantially in the form set forth in Exhibit K.

misconduct.  Without limiting the generality of the foregoing, the Agent (a) may

accordance  with the  advice of such  experts;  (b) makes no  representation  or
warranty  to any  Security  Holder as to,  and shall not be  responsible  to any

any written or oral statement  (including a financial or other such  statement),
instrument,  or other document delivered in connection  herewith or therewith or
furnished to any Security  Holder by or on behalf of GP, NPDC, or MXL; (c) shall
have no duty to ascertain or inquire into GP's,  NPDC's, or MXL's performance or

inquire into the  existence or possible  existence of any Event of Default;  (d)
shall not be responsible to any Security Holder for the due execution, legality,
validity,    enforceability,     effectiveness,     genuineness,    sufficiency,
collectability, or value of this Agreement or the other Transaction Documents or
any instrument or document  executed or issued  pursuant hereto or in connection
herewith,  except  to  the  extent  that  such  may  be  dependent  on  the  due
authorization  and  execution  by the Agent  itself;  (e)  except  as  expressly
provided  herein in respect of  information  and data furnished to the Agent for
distribution  to the  Security  Holder,  shall  have no duty or  responsibility,
either initially or on a continuing basis, to provide to any Security Holder any
information with respect to GP, NPDC, or MXL, whether coming into its possession
before the date hereof or at any time or times  thereafter;  and (f) shall incur
no  liability  under or in respect of this  Agreement  or the other  Transaction
Documents for, and shall be entitled to rely and act upon, any notice,  consent,
certificate or other  instrument or writing  (which may be by e-mail,  facsimile
(telecopier),  telegram,  cable, or other electronic means) believed by it to be
genuine  and  correct  and to have been  signed or sent by the  proper  party or
parties.




         9.3.  Liquidation.  After any  acceleration  of any of amounts  due and
owing under the Notes,  all monies or other  assets  received  by the Agent,  as
repayments  of any of the Notes,  proceeds of exercise of the security  interest
provided by the Mortgage, or otherwise,  shall be applied first to the Agent for
any Agent fees and expenses then due and payable under this Agreement until such
fees and  expenses  are paid in full,  and then to the  holders of the Notes for
their percentage shares of all principal,  interest,  and other amounts then due
and payable from GP until such principal,  interest,  and other amounts are paid
in full.

         9.4.  Successor  Agent.  The Agent may  resign at any time by giving 30
days written notice thereof to the Security Holders, GP, NPDC, and MXL. Upon any
such resignation,  the Security Holders,  with prior written notice to GP, NPDC,
and MXL,  shall have the right to appoint a  successor  Agent.  If no  successor
Agent shall have been so appointed,  and shall have  accepted such  appointment,
within 30 days after such notice of  resignation,  then the  retiring  Agent may
(but shall not be required  to) appoint a  successor  Agent,  upon notice to the
Security Holders, GP, NPDC, and MXL. Upon the acceptance by a successor Agent of
its appointment as Agent hereunder, such successor Agent shall thereupon succeed
to and become vested with all the  properties,  rights,  powers,  privileges and
duties of the former Agent in its capacity as such, without further act, deed or
conveyance.  Upon the effective date of resignation  of a retiring  Agent,  such
Agent  shall  be  discharged  from  its  duties  under  this  Agreement  or  the
Transaction  Documents,  but the provisions of this Agreement shall inure to its
benefit as to any  actions  taken or omitted by it while it was Agent under this
Agreement.

         9.5. Fees and Expenses of Agent. GP shall pay to the Agent from time to
time such  reasonable  fee for its  services  as agent as GP and the Agent shall
agree in writing.  GP shall  reimburse  the Agent  promptly upon request for all
reasonable  disbursements,  advances,  and  expenses  incurred  or made by or on
behalf of it in addition to the fee for its services.  Such expenses may include
the reasonable compensation,  disbursements, and expenses of the Agent's agents,
counsel, and other persons not regularly in its employ.

9.6.     Indemnification.

         (a) The Security Holders and GP, jointly and severally, shall indemnify
the  Agent  from  and  against  any and all  liabilities,  obligations,  losses,
damages,   penalties,   actions,   judgments,   suits,  costs,   expenses,   and
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by, or  asserted  against the Agent in such  capacity in any way  relating to or
arising out of this Agreement or the other  Transaction  Documents or any action
taken or omitted to be taken by the Agent in such  capacity  hereunder  or under
the other  Transaction  Documents;  provided,  that  neither any of the Security
Holders nor GP shall be liable for any portion of such liabilities, obligations,
losses,  damages,  penalties,  actions,  judgments,  suits, costs,  expenses, or
disbursements resulting from the Agent's gross negligence or willful misconduct.
Without  limiting the generality of the foregoing,  each of the Security Holders
and GP agrees to reimburse the Agent,  promptly on demand, for any out-of-pocket
expenses  (including  counsel fees and  disbursements)  incurred by the Agent in
connection with the preparation,  execution,  administration, or enforcement of,
or the preservation of any rights under, this Agreement or the other Transaction
Documents.




         (b)  Without  limiting  Section  9.6(a),  as among GP and the  Security
Holders:

(i)      GP shall be solely liable for, and shall reimburse the Security Holders
         for, and  indemnify  and hold the Security  Holders  harmless  from and
         against,  any claim by the Agent for the fees and expenses of the Agent
         for  which GP is  responsible  under  Section  9.5.

(ii)     The Security Holders shall be solely liable for, and shall reimburse GP
         for, and indemnify and hold GP harmless from and against,  any claim by
         the Agent  under  Section  9.6(a)  resulting  from any action  taken or
         omitted to be taken at the direction of the Security Holders, or any of
         them (except for the fees and expenses provided in Section 9.5), or any
         dispute  among the  Security  Holders.  The  liability  of the Security
         Holders  under this Section  9.6(b)(ii)  shall be joint and several and
         shall be allocated among the Security Holders on a pro rata basis based
         upon the outstanding principal amounts of the Notes.

(iii)    In any circumstance not provided for in Section 9.6(b)(i) or (ii), GP,
         on the one hand, and the Security Holders, on the other, shall
         contribute to the liabilities, obligations, losses, damages, penalties,
         actions, judgments, suits, costs, expenses, and disbursements for which
         any of them may be liable under Section 9.6(a) based on all relevant
         equitable considerations, including the relative fault of GP and the
         Security Holders in the aggregate in connection with the facts which
         resulted in such liabilities, obligations, losses, damages, penalties,
         actions, judgments, suits, costs, expenses, and disbursements.

X.       Indemnification

         10.1.  General.  Each of GP, NPDC, and MXL (the  "indemnifying  party")
shall indemnify and hold harmless each Purchaser and its  affiliates,  officers,
directors, trustees, stockholders, employees, agents, and representatives (each,
an  "indemnified  party")  from and  against  any and all  liabilities,  claims,
demands,  actions,  suits,  losses,  damages,  costs,  and expenses  (including,
without  limitation,  reasonable  attorneys'  fees,  and any  and  all  expenses
whatsoever  incurred  in  investigating,  preparing,  or  defending  against any
litigation,  commenced  or  threatened,  or any  claim  whatsoever,  any and all
amounts paid in settlement of any claim or litigation,  and any of the foregoing
arising out of or relating to the enforcement of this Article X)  (collectively,
"Damages"),  based upon or arising out of a breach of any  covenant,  agreement,
representation,  or warranty made by the indemnifying party in this Agreement or
the other Transaction Documents.

10.2.    Indemnity Procedures.

         (a) An indemnified party seeking  indemnification  under this Agreement
in respect of, arising out of, or involving a claim or demand made by any person
or governmental  authority  against the indemnified  party based upon or arising
out of a breach of any covenant, agreement,  representation, or warranty made by
the indemnifying  party in this Agreement or the other Transaction  Documents (a
"Third Party Claim") shall notify the indemnifying party in writing of the Third
Party Claim  within 10 days after  receipt by the  indemnified  party of written



notice of the Third Party Claim;  provided,  however,  that failure to give such
notification shall not affect the indemnification provided under this Agreement,
except to the extent the  indemnifying  party shall have been prejudiced by such
failure.  Thereafter,  the indemnified  party shall deliver to the  indemnifying
party,  promptly after the indemnified  party's receipt  thereof,  copies of all
notices and documents (including court papers) received by the indemnified party
relating to the Third Party Claim.

         (b) The indemnifying  party shall have the right,  within 30 days after
being so notified,  to assume the defense of such Third Party Claim with counsel
reasonably  satisfactory  to the  indemnified  party. In any such proceeding the
defense of which the indemnifying  party shall have so assumed,  the indemnified
party shall have the right to participate  therein and retain its own counsel at
its own expense  unless (i) the  indemnified  party and the  indemnifying  party
shall  have  mutually  agreed  to  the  retention  of  such  counsel,  (ii)  the
indemnified party shall have reasonably  concluded on the basis of an opinion of
its counsel that there may be one or more legal  defenses  available to it which
are different from or additional to those available to the  indemnifying  party,
or (iii) the named  parties  to any such  proceeding  (including  any  impleaded
parties)  include both the  indemnifying  party and the indemnified  party,  and
representation of both parties by the same counsel would be inappropriate in the
opinion of the indemnified  party's counsel due to actual or potential differing
interests  between  them;  in any such case,  one such  separate  counsel may be
retained  by all  indemnified  parties  as a group at the  indemnifying  party's
expense.  To the extent that the  settlement  of such a Third Party  Claim,  the
defense  of which has been  assumed  by the  indemnifying  party,  involves  the
payment  of  money  only,  the  indemnifying  party  shall  have the  right,  in
consultation  with the  indemnified  party, to settle those aspects dealing only
with the payment of money,  provided that the indemnifying party pays such money
and such  settlement  includes a general  release from the other parties to such
Third Party Claim in favor of the indemnified party. In connection with any such
defense or  settlement,  the  indemnifying  party shall not enter into a consent
decree involving  injunctive or non-monetary  relief or consent to an injunction
without the indemnified  party's prior written consent,  which consent shall not
be unreasonably withheld.

         (c) The  indemnified  party at the  indemnifying  party's expense shall
cooperate in all reasonable  respects with the indemnifying  party in connection
with any  Third  Party  Claims  and the  defense  or  compromise  thereof.  Such
cooperation shall include at the indemnifying  party's expense the retention and
(upon the indemnifying  party's request) the provision to the indemnifying party
of records and  information  reasonably  relevant to the Third Party Claim which
are not confidential,  making employees available on a mutually convenient basis
to provide  additional  information,  and  explanation of any material  provided
under this Agreement.  If the indemnifying  party shall have assumed the defense
of a Third Party Claim, the indemnified party shall not admit any liability with
respect to, or settle,  compromise, or discharge, the Third Party Claim, without
the  indemnifying  party's  prior  written  consent,  which consent shall not be
unreasonably  withheld;  provided,  that  admissions  of facts which a party may
reasonably  be  required  to  make  shall  not be  deemed  to be  admissions  of
liability.




         10.3. Exclusivity. The indemnification provided by this Article X shall
be the sole remedy (other than termination of this Agreement pursuant to Article
XI or  declaring  an Event of Default)  for any matters  relating to Third Party
Claims; provided, that this Section 10.3 shall not prohibit injunctive relief if
available under applicable law.

XI.      Termination

         11.1.  Termination.  This Agreement may be terminated at any time prior
to any Closing:

         (a) by mutual  written  consent  executed  by GP,  NPDC,  MXL,  and the
Purchasers;

         (b) by GP,  by  notice  given to the  Purchasers  in  writing,  without
liability  to GP, NPDC,  or MXL on account of such  termination  (providing  GP,
NPDC, and MXL are not otherwise in default or in breach of this  Agreement),  if
(i) any of the  conditions  to GP and NPDC's  obligations  under this  Agreement
shall not have been  satisfied  or waived in writing by GP and NPDC prior to the
Closing  or (ii) the  Purchasers  shall have  failed to perform in any  material
respect their covenants or agreements  contained herein required to be performed
prior to the Closing,  or shall have  breached any of their  representations  or
warranties  contained  herein,  in each  instance  in a  material  respect  (and
provided that GP and NPDC shall afford the  Purchasers at least 15 Business Days
notice  of and  opportunity  to  cure  such  breach),  unless  such  failure  is
attributable to the breach by GP or NPDC of any of its obligations to consummate
the  transactions  contemplated  hereby  or of  any  of  its  other  obligations
hereunder;

         (c) by the Purchasers, acting jointly, by notice given to GP, NPDC, and
MXL in  writing,  without  liability  to  the  Purchasers  on  account  of  such
termination  (providing the Purchasers are not otherwise in default or in breach
of this Agreement),  if (i) any of the conditions to the Purchasers' obligations
under this  Agreement  shall not have been satisfied or waived in writing by the
Purchasers  prior to the Closing or (ii) GP,  NPDC,  or MXL shall have failed to
perform in any material  respect its  covenants or agreements  contained  herein
required to be performed prior to the Closing, or shall have breached any of its
representations  or warranties  contained herein, in each instance in a material
respect (and  provided  that the  Purchasers  shall afford GP, NPDC,  and MXL at
least 15 Business Days notice of and  opportunity  to cure such breach),  unless
such failure is  attributable  to the breach by the  Purchasers  of any of their
obligations  to consummate  the  transactions  contemplated  hereby or of any of
their other obligations hereunder;

         (d) by any of GP, NPDC, or the Purchasers, by notice given to the other
parties in writing,  without liability, if the transactions  contemplated hereby
shall  violate  any  non-appealable  final  order,  decree,  or  judgment of any
governmental  authority  having  competent  jurisdiction  or if there shall be a
statute,  rule, or regulation that makes the  transactions  contemplated  hereby
illegal or otherwise  prohibited  provided  that the party  seeking to terminate
this Agreement under this Section 11.1(d) shall have used reasonable  commercial
efforts to avoid the issuance of any such order, decree, or judgment; or




         (e) by any of GP, NPDC, or the Purchasers, by notice given to the other
parties in writing,  without  liability,  if the  Closing  shall not occur on or
prior to the date which falls 60 days following the date of this Agreement.

         11.2.  Effect of  Termination.  Upon any  termination of this Agreement
pursuant  to Section  11.1 this  Agreement  shall  become  wholly void and of no
further force or effect (except Section 8.9, this Section 11.2, and Article XII)
and none of the parties  shall have any  liability or  obligation  to the others
arising out of this  Agreement  except for any liability  arising from a party's
breach of this Agreement prior to such termination.

XII.     Miscellaneous

         12.1.  Costs and  Expenses.  GP  agrees to pay on demand  all costs and
expenses of the  Purchasers in connection  with the  preparation,  execution and
delivery of this Agreement and the other  Transaction  Documents,  and the other
instruments  and documents to be delivered  hereunder  (including the reasonable
fees and  out-of-pocket  expenses  of Paul,  Hastings,  Janofsky  & Walker  LLP,
counsel for the Purchasers,  with respect  thereto),  in an amount not to exceed
$100,000.

         12.2.  Further  Actions.  At any time and from time to time, each party

Agreement.

to the subject  matter hereof and supersede all existing  agreements  among them
concerning such subject matter.

         12.4.  Amendments and Waivers.  Any provisions of this Agreement may be
modified,  amended,  or waived if, but only if, such modification,  amendment or
waiver is in writing and is signed by GP, NPDC,  MXL, and each of the Purchasers
or, subject to Section 9.1, the Agent; provided that the Agent shall be required
to consent to any modification,  amendment, or waiver of the rights or duties of
the Agent; and provided,  further,  that, after the Spin-Off Date, the signature

breach of any term of this Agreement  shall not operate as or be construed to be

this  Agreement.  The  failure  of a party or the  Agent to insist  upon  strict
adherence  to any term of this  Agreement on one or more  occasions  will not be
considered a waiver or deprive  that party or the Agent of the right  thereafter

or equity.

         12.7. Binding Effect. No party may sell, assign, transfer, or otherwise

inure  to the  benefit  of the  parties  hereto  and  the  respective  permitted
successors,  assigns, and personal representatives of the parties. Any attempted
sale,  assignment,  transfer,  conveyance,  or  delegation  in violation of this
Section 12.7 shall be void. The provisions of this Agreement  shall inure to the



benefit of each  indemnified  party and its  successors  and  assigns  (if not a
natural  person) and his  assigns,  heirs,  and personal  representatives  (if a
natural person).

         12.8. No Third Party Beneficiaries. This Agreement does not create, and
shall not be construed as creating,  any rights  enforceable by any person not a
party to this Agreement (except as provided in Article IX, Section 12.7, and the
other Transaction Documents).

         12.9.  Separability.  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.

         12.10.  Headings.  The  headings  in  this  Agreement  are  solely  for

governed by and construed in accordance  with the laws of the State of New York,
