                        AGREEMENT OF MERGER

     THIS AGREEMENT OF MERGER, (sometimes referred to as the "Agreement" or
the "Merger"), dated as of August  27,  1997,  is  among  NICHOLS  RESEARCH
CORPORATION, a Delaware corporation ("NRC"); NRC's wholly owned subsidiary,
NICHOLS  SELECT  CORPORATION,  a  Delaware  corporation  ("Subsidiary"  and
sometimes  referred  to  as  the  "Surviving  Corporation"); TXEN, INC., an
Alabama corporation, ("TXEN") and the holders of  all  of  the  $0.002  par
value  Class  A  common  stock of TXEN listed on the signature page to this
Agreement (the "Shareholders").   Subsidiary  and  TXEN  shall sometimes be
referred to collectively as the "Constituent Corporations" and individually
as a "Constituent Corporation."  The Shareholders execute  and deliver this
Agreement  for  the  purposes  of  (i)  joining in the representations  and
warranties of TXEN, (ii) providing indemnification to NRC and the Surviving
Corporation  and  (iii)  acknowledging  receipt  and  acquiescence  in  the
disclosures of certain matters with respect to NRC and its common stock.

                       W I T N E S S E T H:

     Each  Constituent  Corporation  deems it  advisable  for  the  general
welfare  of  Constituent  Corporation  and   its   shareholders   that  the
Constituent  Corporations merge into a single corporation pursuant to  this
Agreement and  the  applicable  laws of the States of Delaware and Alabama.
Accordingly,  TXEN  shall be merged  with  and  into  the  Subsidiary  with
Subsidiary as the Surviving  Corporation in accordance with and pursuant to
the provisions of Section 252  of  the General Corporation Law of the State
of Delaware and Section 10-2B-11.07  of  the  Alabama  Business Corporation
Act.   The  name  of  the  Surviving  Corporation shall be "NICHOLS  SELECT
CORPORATION."   The  Shareholders  of  the  Constituent  Corporations  have
consented  to  this Agreement of Merger in  accordance  with  Delaware  and
Alabama law.  NRC  will  make available to Subsidiary (as a contribution to
capital) a sufficient amount  of cash and a sufficient number of restricted
(and unregistered) shares of NRC common stock, par value of $0.01 per share
(the "NRC Common Stock") to effect the Merger.

     It is agreed that the terms  and conditions of the Merger and the mode
of carrying it into effect shall be as follows:

                    SECTION 1.  EFFECTIVE DATE

     On August 29, 1997 (the "Closing  Date"),  provided  the conditions to
the consummation of this Agreement have been satisfied or waived, a meeting
(the  "Closing")  shall  take  place  at  the office of Ritchie &  Rediker,
L.L.C., in Birmingham, Alabama, at which time the parties to this Agreement
shall execute and deliver (i) the Articles  of  Merger  and  Certificate of
Merger  attached  hereto as Exhibits "A" and "B", respectively,  to  comply
with applicable filing  and recording requirements of the States of Alabama
and  Delaware and (ii) all  other  documents,  certificates,  opinions  and
instruments contemplated herein.  The date of such Articles and Certificate
shall be the Closing Date and the effective date of the Merger set forth in
such Articles  and  Certificate  shall  be  August 31, 1997, at 11:59 p.m.,
Central Daylight Saving Time (the "Effective  Date").  On the Closing Date,
an executed counterpart of the Certificate of Merger and Articles of Merger
shall  be  personally  delivered, mailed or transmitted  by  facsimile  for
filing in the appropriate  filing  offices  in  the  States of Delaware and
Alabama.

                     SECTION 2.  GOVERNING LAW

     The Surviving Corporation shall be governed by the  laws  of the State
of Delaware.


    SECTION 3.  CAPITALIZATION AND CERTIFICATE OF INCORPORATION

     The number of authorized shares of the capital stock of the  Surviving
Corporation  shall be 1,000 shares of common stock, par value of $1.00  per
share.  The Certificate  of Incorporation of Subsidiary as in effect on the
date of this Agreement shall  be  the  Certificate  of Incorporation of the
Surviving Corporation from and after the Effective Date.

                        SECTION 4.  BYLAWS

     The Bylaws of Subsidiary as in effect on the date  of  this  Agreement
shall be the Bylaws of the Surviving Corporation.

      SECTION 5.  MERGER CONSIDERATION, CONVERSION OF SHARES
          AND CAPITAL STOCK OF THE SURVIVING CORPORATION

     5.1  CONTRIBUTION TO CAPITAL.  On or prior to the Effective Date,  NRC
shall transfer and deliver to Subsidiary, as a contribution to its capital,
such  number of shares of NRC Common Stock and such amount of cash or other
immediately funds as shall be necessary to carry out the provisions of this
Section 5.

     5.2  STOCK  OF  SUBSIDIARY; CLASS B COMMON STOCK.  None of the capital
stock  of  Subsidiary issued  and  outstanding  immediately  prior  to  the
Effective Date  shall  be  converted  as a result of the Merger, but all of
such shares of capital stock shall remain  issued and outstanding shares of
capital stock of the Surviving Corporation.   On  the  Effective Date, each
share of $0.002 par value Class B common stock of TXEN,  all  of  which  is
owned  by  NRC,  shall be cancelled and extinguished and none of the merger
consideration set forth in Section 5.3 below shall be paid to NRC.

     5.3  MERGER CONSIDERATION.   The  Class  A  common  stock of TXEN (the
"TXEN  Common  Stock")  issued  and  outstanding immediately prior  to  the
Effective Date (excluding shares held  by  TXEN  as  treasury  stock, which
shares  shall  be cancelled and extinguished on the Effective Date)  shall,
upon the Effective  Date, by virtue of the Merger and without any action on
the part of the holders  thereof,  be exchanged for and converted into such
number of shares of fully paid and nonassessable  NRC Common Stock having a
value as hereinafter determined of $26,324,706.77 and cash in the amount of
$17,550,265.13  (the  "Merger Consideration").  The TXEN  Common  Stock  so
exchanged and converted  is  herein sometimes referred to as the "Converted
TXEN  Stock."   The value of the  NRC  shares  of  Common  Stock  shall  be
determined based  on  the  average of the daily weighted sale price of such
stock as quoted by National  Association  of  Securities  Dealers Automated
Quotation  System  for  the  ten  business  day  period  ending  five  days
immediately preceding the Closing.  The Merger Consideration shall  be paid
and  allocated  to each Shareholder in accordance with Exhibit "C" attached
hereto for each Shareholder and made a part hereof.  The Shareholders shall
deposit into escrow  a  portion  of  the Merger Consideration identified on
Exhibit  "C"  for  each  Shareholder to be  held  pursuant  to  the  Escrow
Agreement attached hereto as Exhibit "D."

     5.4  EXCHANGE OF STOCK CERTIFICATES.  As promptly as practicable after
the  Effective  Date,  each  holder   of   an  outstanding  certificate  or
certificates theretofore representing shares  of Converted TXEN Stock shall
surrender  the  same  to  an agent or agents designated  by  the  Surviving
Corporation,  and  shall thereupon  be  entitled  to  receive  in  exchange
therefor  the Merger  Consideration  as  shown  on  Exhibit  "C"  for  each
Shareholder.   Dividends  payable  after  the  Effective Date to holders of
record in respect of shares of NRC Common Stock into which certificates for
shares of Converted TXEN Stock shall be exchangeable  shall  not be paid to
holders  of such certificates until their certificates are surrendered  for
exchange.   Until so surrendered, each outstanding certificate which, prior
to the Effective Date, represented Converted TXEN Stock shall be deemed for
all corporate  purposes  to  evidence ownership of the Merger Consideration
into which the shares of Converted  TXEN  Stock prior to the Effective Date
shall have been converted.

     5.5  EXCHANGE AGENTS.  NRC may direct  the  Surviving  Corporation  to
appoint  an  NRC  employee,  agent  or  representative,  including, without
limitation,  Allen  Dillard,  as  the exchange agent for purposes  of  this
Section  of  the  Merger Agreement.  Adoption  of  this  Agreement  by  the
Shareholders of TXEN  shall  constitute  ratification of the appointment of
such exchange agent at the direction of NRC or the Surviving Corporation.

     5.6  STOCK OPTIONS.

          (a)  At the Effective Date, each  option  to  purchase  shares of
TXEN Class A Common Stock pursuant to an option grant under the TXEN, Inc.,
1996  Incentive Stock Option Plan or the TXEN, Inc., Key Employee Incentive
Stock Option  Plan  (the  "Option  Plans")  which  are  outstanding  at the
Effective  Date (the "TXEN Options"), whether or not exercisable, shall  be
converted into  and become rights with respect to NRC Common Stock, and NRC
shall assume each  TXEN  Option, in accordance with the terms of the Option
Plan by which it is evidenced,  except  that  from  and after the Effective
Date,  (i) NRC and NRC's Board of Directors shall be substituted  for  TXEN
and the  Committee  of TXEN's Board of Directors (including, if applicable,
the entire Board of Directors  of  TXEN)  administering  such Option Plans,
(ii) each TXEN Option assumed by NRC may be exercised solely  for shares of
NRC Common Stock, (iii) the number of shares of NRC Common Stock subject to
such  options  shall be equal to the number of shares of TXEN Common  Stock
subject to each  such  TXEN  Option immediately prior to the Effective Date
multiplied  by .451677 (the "Exchange  Ratio"),  and  (iv)  the  per  share
exercise price  under  each  such TXEN Option shall be adjusted by dividing
the per share exercise price under  each  such  TXEN Option by the Exchange
Ratio and rounding up to the nearest cent.  Notwithstanding  the provisions
of  clause  (iii) of the preceding sentence, NRC shall not be obligated  to
issue any fraction  of  a  share  of NRC Common Stock upon exercise of TXEN
Options, and any fraction of a share  of  NRC  Common  Stock that otherwise
would be subject to a converted TXEN Option shall represent  the  right  to
receive  a cash payment upon exercise between the market value of one share
of NRC Common  Stock  at  the  time  of exercise of such option and the per
share exercise price of such option.   The market value of one share of NRC
Common Stock at the time of exercise of  an  option  shall  be  the closing
price  of such NRC Common Stock on the Nasdaq National Market (as  reported
by  THE WALL  STREET  JOURNAL  or,  if  not  reported  thereby,  any  other
authoritative source selected by NRC) on the last trading day preceding the
date  of  exercise.   NRC  and  TXEN  agree  to take all necessary steps to
effectuate the foregoing provisions of this Section 5.6.

          (b)  As soon as practicable after the  Effective  Date, NRC shall
deliver  to  the  participants  in the Option Plans an appropriate  notice,
setting forth such participant's  rights  pursuant  thereto  and the grants
subject to such Option Plans shall continue in effect on the same terms and
conditions  (subject  to  the adjustments required by Section 5.6(a)  after
giving effect to the Merger).  Within 90 days after the Effective Date, NRC
shall file a registration statement  on Form S-8 (or any successor or other
appropriate forms), with respect to the  shares of NRC Common Stock subject
to  such  options  and shall use its reasonable  efforts  to  maintain  the
effectiveness of such  registration  statements  (and  maintain the current
status of the prospectus or prospectuses contained therein)  for so long as
such options remain outstanding.

          (c)  All contractual restrictions or limitations on transfer with
respect  to TXEN Common Stock awarded under the Option Plans or  any  other
plan, program  or contract of TXEN, to the extent that such restrictions or
limitations shall  not  have  already  lapsed  (whether  as a result of the
Merger  or otherwise), and except as otherwise expressly provided  in  such
plan, program,  or  contract,  shall  remain  in full force and effect with
respect to shares of NRC Common Stock into which  such  restricted stock is
converted pursuant to Section 5.6 of this Agreement.

          (d)  TXEN has an option to purchase 119,732 shares of TXEN Common
Stock  from  Thomas L. Patterson and Paul D. Reaves, which  constitute  the
source of the  TXEN  Common Stock needed to fund  the Option Plans.  At the
Closing, such option shall  be  assigned  by  virtue  of  the Merger to the
Surviving Corporation which shall thereupon have the right to purchase from
Messrs. Patterson and Reaves the shares of NRC Common Stock into which such
119,732 shares of TXEN Common Stock have been converted for  the purpose of
funding the Option Plans with NRC Common Stock.

     5.7  RESTRICTED STOCK.  The NRC Common Stock to be transferred  to the
Shareholders in exchange for their TXEN Common Stock will not be registered
under the Securities Act of 1933 (the "1933 Act") or the securities laws of
any state, and will therefore be restricted securities.  Consequently,  the
NRC  Common Stock to be received by the Shareholders in the Merger will not
be transferrable  unless  registered  under  the  1933  Act  or exempt from
registration thereunder and registered under securities laws of  applicable
states or exempt from registration thereunder.  By their signature  to this
Merger  Agreement, each Shareholder represents and warrants that he or  she
has been  advised that the NRC Common Stock will be "Restricted Securities"
within the meaning of the 1933 Act and applicable state securities laws and
further represents  and  warrants  that  he  or she has been advised of the

     lease any real property.  All real property noted on Schedule 10.13 as
     being leased is referred  to  herein as the "Leased Real Property" and
     all  leases relating to the Leased  Real  Property  are  disclosed  on
     Schedule 10.13 and are referred to herein as the "Leases."  TXEN has a
     good and  valid leasehold as to the Leased Real Property leased by it,
     free and clear  of  all  mortgages, security interests, title defects,
     pledges,  liens  and the possibility  of  liens,  charges,  tenancies,
     restrictions and encumbrances  other  than Taxes and assessments, both
     general and special, which are a lien but not yet due and payable that
     do not, individually or in the aggregate,  materially detract from the
     value of the Leased Real Property or materially  impair  the  use  and
     operation  thereof  in carrying on the business of TXEN.  There are no
     pending or, to the best  knowledge  of TXEN, threatened proceedings in
     eminent  domain  involving the Leased Real  Property  or  any  portion
     thereof, or for a sale in lieu thereof, or of any plans for a possible
     widening of the streets  abutting  the  Leased  Real  Property  or the
     imposition of any special taxes or assessments against the Leased Real
     Property  or any portion thereof.  To the best knowledge of TXEN,  the
     applicable zoning (without reliance on any variance, special permit or
     nonconforming  use  or  other  similar  use), building, environmental,
     health and safety laws and regulations permit as a matter of right and
     without the incurrence by Surviving Corporation  of  any obligation or
     liability  (including the obligation to incur any costs  or  expenses)
     the continued use of the Leased Real Property by Surviving Corporation
     for the same  purposes  and  uses as same have been heretofore used by
     TXEN, including the operation of TXEN's business.

          (b)  Except  as  disclosed   on  Schedule  10.13,  there  are  no
     outstanding written or oral leases  covering  or in any way affecting,
     and there are no tenants occupying or having the  right to occupy, the
     Leased Real Property or any part thereof, other than  the  Leases.  To
     the  best of TXEN's knowledge, no person or entity has any right  with
     respect  to  such Leased Real Property (whether by option to purchase,
     land contract,  or  otherwise)  which  would prevent or interfere with
     possession  or  use  of  the  Leased Real Property  by  the  Surviving
     Corporation on and after the Effective Date.

          (c)  The  Leases  are  in  full   force  and  effect.   TXEN  has
     heretofore provided to NRC a complete, true,  and  correct copy of the
     Leases, including any and all modifications or amendments  thereof and
     any   supplements   thereto.   All  material  terms,  conditions,  and
     provisions of the Leases  to  be  performed  by  TXEN and, to the best
     knowledge  of  TXEN,  by  the  landlords,  have been duly  and  timely
     performed and complied with.  To the best knowledge  of TXEN, no event
     has occurred or failed to occur which with the giving  of  notice, the
     passage of time, or both, would constitute a default by the  landlords
     or  TXEN  under any of the Leases.  The landlords have not waived,  or
     extended the time for performance of, any obligation of TXEN under any
     of the Leases.   There  are  no  security  deposits  or  prepaid  rent
     (including  last  month's  rent in advance) with respect to the Leased
     Real Property.

          (d)  To the best knowledge  of TXEN, there are no prohibitions or
     other limitations, whether contained  in  the  Leases or otherwise, on
     TXEN's right to transfer the Leased Real Property  in  connection with
     this  Agreement.  Except as specifically noted on Schedule  10.13,  no
     consent,  authorization,  or  approval is required under the Leases in
     connection  with the consummation  of  the  transactions  contemplated
     hereby or TXEN's  ability  to consummate the transactions contemplated
     hereby.

     10.14 TITLE AND CONDITION OF  THE  ASSETS  AND PROPERTIES.  The assets
and properties currently utilized by TXEN, whether  owned or leased, are in
all  material  respects  in  good operating condition and  repair  and  are
suitable for the purposes for  which  they  are presently being used.  Such
assets and properties conform in all material  respects  to  all applicable
laws,  ordinances,  and regulations, and TXEN has not received any  written
notice to the contrary.  TXEN is the sole and exclusive legal and equitable
owner of all right, title  and  interest  in,  and  has good and marketable
title to, all of its assets and properties, tangible and intangible, except
for  such  Personal  Property  that  is  leased  by  TXEN and  specifically
identified  as  being  leased  on  Schedule  10.6 and except  for  licenses
specifically identified on Schedules 10.15 or 10.16.

     10.15  PROPRIETARY  RIGHTS.   Schedule 10.15  sets  forth  a  list  of
material inventions, trade secrets,  processes, proprietary rights, product
specifications,   blueprints,   drawings,   technical   data,   engineering
information, other proprietary knowledge and know-how, patents, trademarks,

material  documentation related thereto, and all licenses and agreements in
respect  thereof  and  applications  therefor  (collectively,  "Proprietary
Rights") used  or  related  to  TXEN's  business.   The  Proprietary Rights
described on Schedule 10.15 include all of the Proprietary Rights necessary
for   the   operation   of  TXEN's  business.   Except  as  set  forth   on
Schedule 10.15, which includes  a listing of contracts or licenses pursuant
to which TXEN uses the intellectual property of third parties, with respect
to the Proprietary Rights, (a) TXEN  is the sole and exclusive owner of and
has the sole and exclusive right to use  its  Proprietary  Rights;  (b)  no
action,  suit, arbitration, or other proceeding or investigation is pending
or,  to  the   best  knowledge  of  TXEN,  threatened  which  involves  any
Proprietary Rights,  (c)  to  the  best  knowledge  of  TXEN,  none  of the
Proprietary  Rights  infringes  upon, conflicts with, or otherwise violates
the rights of others or is being  infringed upon by others, (d) none of the
Proprietary Rights is subject to any  outstanding  order, decree, judgment,
stipulation,  or charge, (e) there are no royalty, commission,  or  similar
arrangements and no licenses, sublicenses, or agreements relating to any of
the  Proprietary   Rights,   (f)  TXEN  has  not  received  any  notice  of
interference or infringement of  or by the Proprietary Rights, (g) TXEN has
not  agreed  to  indemnify  any  person   or  entity  for  or  against  any
infringement  of or by the Proprietary Rights,  (h)  no  other  Proprietary
Rights not owned  by TXEN are necessary for the conduct of TXEN's business,
and (i) to the best  knowledge  of  TXEN,  no  other  party  is operating a
business  or  otherwise  acting  in  violation  or infringement of,  TXEN's
Proprietary Rights.  Except as set forth on Schedule  10.15,  TXEN has good
and  marketable  title to the Proprietary Rights listed on Schedule  10.15,
free and clear of  all security interests, liens, pledges, encumbrances and
restrictions.  Except as set forth on Schedule 10.15, all rights of TXEN in
and to its Proprietary  Rights are transferable to Surviving Corporation as
contemplated herein without  the  consent  or  approval of any third party.
TXEN is not subject to any judgment, order, writ,  injunction, or decree of
any court, arbitrator, or governmental agency or instrumentality,  domestic
or  foreign,  and is not party to any agreement, which restricts or impairs
the use of any Proprietary Rights.

     10.16 SOFTWARE AND INFORMATION SYSTEMS.

          (a)  The  software  described  on  Schedule  10.16  includes  all
     information  systems,  programs and software, other than non-exclusive
     commercial  software,  used  in  or  related  to  TXEN's  business  or
     necessary for the operation  of  such  business.  Schedule 10.16 lists
     all such software and identifies (a) software  which is owned by TXEN,
     (b) software which is licensed to TXEN, and (c)  any other software in
     which TXEN has any use, possessory, or proprietary rights and which is
     used  in  or  related  to  its  business.   Except  as  set  forth  on
     Schedule  10.16,  TXEN  has  the sole and exclusive right, title,  and
     interest in and to all software  listed  on Schedule 10.16.  Except as
     set forth on Schedule 10.16, TXEN has good and marketable title to the
     software  listed,  free  and clear of all security  interests,  liens,
     pledges,  encumbrances and  restrictions.   Except  as  set  forth  on
     Schedule 10.16,  all of the software which is owned by TXEN, including
     all related source  codes  and  documentation, is owned solely by TXEN
     and has not been disclosed to any  unaffiliated entity or person.  The
     proprietary software owned by TXEN includes,  without limitation, TXEN
     FirstStepp.   The  proprietary software owned by  TXEN  is  (i)  owned
     exclusively by TXEN,  (ii)  not subject to any liens, claims, security
     interests  or  encumbrances, (iii)  not  subject  to  any  outstanding
     licenses or agreements, except for the non-exclusive licensing of such
     proprietary software  by  TXEN  to customers in the ordinary course of
     business in the manner disclosed  to Subsidiary, (iv) merchantable and
     fit for the purposes for which such  software is intended for use, (v)
     conforming  in  all  material  respects with  the  specifications  and
     documentation for such software  and  (vi) without material defects or
     material programming errors.

          (b)  Schedule 10.16 incorporates by  reference manuals (copies of
     which have been made available to and furnished to NRC) which describe
     the  functions of all proprietary information  systems,  programs  and
     software  of  TXEN.   TXEN  has  documentation  in  reasonable  detail
     relating  to  all  such  proprietary information systems, programs and
     software.  Schedule 10.16  identifies  each  person  or entity to whom
     TXEN has licensed or granted any other rights to any other proprietary
     information  systems, programs and software.  Except as  disclosed  on
     Schedule 10.16(b),  no  source code or object code of TXEN is escrowed
     for the benefit of any third  party.   Except as disclosed on Schedule
     10.16(b), none of the information systems,  programs  and  software of
     TXEN  infringe on any patents, trademarks, copyrights or other  rights
     or intellectual  property  rights  of  any third persons.  To the best
     knowledge of TXEN, no information systems,  programs and software used
     or owned by any third person or entity infringe  on any rights of TXEN
     in  and  to  the information systems, programs and software  of  TXEN.
     TXEN has taken  reasonable  measures necessary to maintain and protect
     the information systems, programs  and  software of TXEN and no claims
     have been asserted by any person or entity  to  the use of the same or
     challenging or questioning the validity or effectiveness  of the same,
     and,  to  the best knowledge of TXEN, there is no valid basis  to  any
     such claim.

          (c)  Schedule  10.16 also contains a list of the current software
     development and consulting  activities and projects of TXEN.  TXEN has
     described such projects and developments  to  NRC.   TXEN  knows of no
     impediments   to  fully  developing  and  exploiting  the  information
     systems, programs  and  software  currently  under  development  or to
     performing its currently pending consulting contracts.

     10.17 CONTRACTS AND LEASES.  Schedule 10.17 sets forth an accurate and
complete  list  of  each  of  the  following  verbal  or written contracts,
agreements and leases ("Contracts") to which TXEN is a party:

          (a)  Personal and real property leases;

          (b)  Material   licenses,   including   without  limitation,
     licenses  of  software,  intellectual  property  or   Proprietary
     Rights;

          (c)  Contracts   for  capital  expenditures  in  excess   of
     $25,000;

          (d)  Contracts for  the purchase of machinery, equipment, or
     fixtures involving expenditures in excess of $25,000;

          (e)  Royalty agreements;

          (f)  Agencies;

          (g)  Marketing  agreements,  reseller  agreements,  original
     equipment manufacturer agreements and training agreements;

          (h)  Contracts, arrangements,  consulting  agreements, bids,
     proposals, software agreements, licenses, maintenance agreements,
     support agreements, warranties, purchase orders,  agreements,  or
     commitments  of  any  kind  or  character which (i) relate in any
     material  way  to  the  business  activities   of  TXEN,  to  the
     information systems, programs and software of TXEN  or  to TXEN's
     services with respect thereto or (ii) involve the expenditure  by
     or receipt of TXEN of more than $25,000 or involve any commitment
     or obligations of TXEN for a period of over one (1) month;

          (i)  Instruments  evidencing  or  related  to  the  deferred
     purchase price of property in excess of $25,000 (including  trade
     payables);

          (j)  Joint  venture,  partnership, limited liability company
     or other arrangements involving a sharing of profits;

          (k)  Contracts  with  any   government   or  any  agency  or
     instrumentality thereof;

          (l)  Contracts with respect to the discharge  or  removal of
     effluent, wastes, or pollutants;

          (m)  Contracts   with  any  dealer,  agent,  representative,
     manufacturer's representative, distributor, or sales agent;

          (n)  Employee benefit,  bonus  or  compensation  agreements,
     collective bargaining agreements or employment agreements  or any
     other  agreements  or  arrangements  with  respect  to  employees
     (including,  without  limitation,  a  list  of  employee  accrued
     vacation and sick leave, severance, and other benefits);

          (o)  Confidentiality or non-competition agreements; and

          (p)  Other  agreements  not  entered  into  in  the ordinary
     course of business.

Except as set forth on Schedule 10.17, to the best knowledge  of TXEN, TXEN
has performed and is performing all material obligations to be performed by
it  under  each  Contract,  and,  to the best knowledge of TXEN, the  other
parties thereto have performed and  are performing all material obligations
to be performed by them.  To the best  knowledge  of  TXEN,  TXEN is not in
default,  and  has not received any notice of default, under any  Contract.
No event has occurred  which,  with  notice or lapse of time or both, would
constitute a default by TXEN thereunder.   To  the  best knowledge of TXEN,
none  of the Contracts is subject to any impending cancellation  or  breach
that will  result  in  a  loss or otherwise materially adversely affect the
operations of TXEN's business.   Except as disclosed on Schedule 10.17, all
Contracts  are assignable to Surviving  Corporation  and  no  consents  are
required except as provided on Schedule 10.3.

     10.18 MATERIAL  COMMITMENTS.   As used in this Section 10.18, the term
"Material Commitments" means each Contract  of TXEN which obligates TXEN to
sell, license, distribute, deliver or provide  products  or  services for a
consideration  in excess of $25,000 or over a period of more than  one  (1)
month.  Schedule  10.18  sets  forth  a "Project List" with respect to each
Material  Commitment.   The  Project  List  sets  forth  TXEN's  production
schedule or performance schedule, and budget,  with regard to each Material
Commitment.  Except as described in the Project  List,  the  performance of
TXEN  or  any  other  party  involved with each Material Commitment  is  on
schedule and within budget, and no practical or technological problems have
been encountered that might reasonably  be expected to impede completion or
materially  increase  the  cost  of  TXEN's  performance.    Each  Material
Commitment  was  made on a basis calculated to produce a profit  under  the
circumstances prevailing  when  it  was  made, and TXEN is not aware of any
circumstances that might reasonably be expected  to prevent the realization
of  a  profit.   Except  as  set  forth  on the Project List,  no  Material
Commitment involves the development of any  product  or technology that, to
the best knowledge of TXEN, would infringe on the proprietary rights of any
other party.

     10.19  WARRANTIES,  SERVICE  COMMITMENTS, AND MAINTENANCE  AGREEMENTS.
Schedule 10.19 contains a correct and  complete  list  of  all  warranties,
service  commitments,  and  maintenance  and/or  support agreements, and  a
statement or description of the warranties and commitments  (e.g. length of
warranty, claims covered, etc.) including, without limitation, all software
service and maintenance agreements, in effect with respect to  any products
or  services heretofore manufactured, sold, licensed or provided  by  TXEN.
Except  as  described  on  Schedule  10.19, there are no express or implied
warranties outstanding with respect to  products or services created, sold,
licensed, provided or otherwise distributed  by  TXEN.   The  warranty  and
return  experience for the three years ended June 30, 1997, is set forth on
Schedule  10.19.   Except  as  set  forth on Schedule 10.19, since June 30,
1994,  no warranty or service claim in  excess  of  $5,000  has  been  made
against  TXEN,  or  is  pending  or,  to  the  best  knowledge  of TXEN, is
threatened  in  connection with any product or service manufactured,  sold,
licensed or provided by TXEN.

     10.20 PERMITS AND LICENSES; COMPLIANCE WITH LAWS.  Except as set forth
on Schedule 10.20,  TXEN  does  not  own any material permits, licenses, or
other governmental authorizations, and  none are required for the operation
of  the business as presently conducted.   Neither  the  ownership  of  its
assets  by  TXEN,  nor  the  operation  of  its  business  as presently and
ordinarily conducted, violates any applicable order, law, ordinance,  code,
or  regulation.   No  investigation is pending or, to the best knowledge of
TXEN, threatened concerning  any such matter, and TXEN has not received any
notice of any such violation and no basis therefor exists.

     10.21  EMPLOYEE BENEFITS.   Schedule  10.21  sets  forth  an  employee
benefits list,  which  identifies  each agreement, plan, or arrangement for
employee benefits, including any bonus,  deferred  compensation, severance,
disability, sick pay, salary continuation, death benefit,  vacation,  stock
purchase  or stock option, hospitalization or other medical, life, or other
insurance,  supplemental  unemployment benefit, profit-sharing, pension, or
retirement plan or arrangement  maintained  or  contributed  to  by TXEN in
connection  with  its business (the "Benefit Plans").  Except as identified
on Schedule 10.21,  none  of  TXEN's  Benefit Plans is an "employee pension
benefit plan" as defined in Section 3(2)  of  ERISA.  To the best of TXEN's
knowledge, all of the Benefit Plans and related trusts are in form and have
been administered in compliance with all applicable  laws,  including ERISA
and  the  Code;  none  of  the  Benefit  Plans  or  related trusts, or  any
administrator  or  trustee  thereof, or party-in-interest  or  disqualified
person thereto has engaged in a transaction that could cause any of them to
be liable for a civil penalty  under Section 409 or 502(i) or other section
of ERISA or a tax under Section 4975 or 4976 or other section of Chapter 43
of Subtitle D of the Code; all amounts  required  to  be paid by TXEN to or
pursuant to each of the Benefit Plans or related trusts  on  or  before the
date of this Agreement have been paid; no employee pension benefit plan has
incurred any "accumulated funding deficiency," as defined in Section 412 of
the Code; no "reportable event" within the meaning of Title IV of ERISA has
occurred  with respect to any Benefit Plan subject thereto; and, except  as
described on  Schedule  10.21,  TXEN is not obligated to pay any additional
amounts to or pursuant to, and have  not guaranteed the obligations of, any
Benefit Plan or related trust.  No employees  of  TXEN  participate  in any
"multi-employer  pension  plan"  within  the  meaning of the Multi-employer
Pension Plan Amendments Act of 1980, as amended, and TXEN does not have any
liability under ERISA for any complete or partial  withdrawal from any such
multi-employer plan.  To the best of TXEN's knowledge,  no  liability under
Title  IV  of  ERISA  has  been  incurred by TXEN or any trade or business,
whether  or  not incorporated, that  would  be  aggregated  with  TXEN  for
purposes of imposition  of  liability  under  Title  IV of ERISA (an "ERISA
Affiliate")  that has not been satisfied in full, and no  condition  exists
that presents,  nor  will the consummation of the transactions contemplated
by this Agreement directly  result  in, a material risk to TXEN or an ERISA
Affiliate of incurring a liability under  such  Title IV.  Neither TXEN nor
an  ERISA  Affiliate,  nor  any  of  their respective directors,  officers,
employees,  or  fiduciaries,  has  committed   any   breach   of  fiduciary
responsibility  imposed  by  ERISA  or any other applicable law that  would
subject  TXEN  to  liability  under ERISA  or  any  other  applicable  law,
contract,  agreement,  or  commitment.    The   Pension   Benefit  Guaranty
Corporation  ("PBGC")  has  not  instituted  proceedings  to terminate  any
Benefit  Plans  in  which TXEN participates, and no condition  exists  that
presents a risk that  such proceedings will be instituted.  No Benefit Plan
provides benefits, including,  without limitation death or medical benefits
(whether  or not insured), with respect  to  current  or  former  employees
beyond their  retirement  or  other  termination  of  service  (other  than
(i) coverage mandated by applicable law, (ii) deferred compensation accrued
on the books of TXEN, (iii) death benefits or retirement benefits under any
"employee pension benefit plan," as that term is defined in Section 3(2) of
ERISA,  or  (iv) benefits the full cost of which is borne by the current or
former employee  (or  his  or  her  beneficiary)).   If  a  Benefit Plan is
designed  to  satisfy  the  requirements  of  Section  125,  Section   401,
Section  401(k), Section 409, Section 501(c)(9), Section 4975(e)(7), and/or
Section 4980B  of  the  Code,  the Benefit Plan satisfies such section.  No
"leased employee," as that term  is  defined in Section 414(n) of the Code,
performs services for TXEN.  TXEN has  heretofore delivered to NRC true and
correct copies of all of the Benefit Plans,  the  most recent determination
letters from the Internal Revenue Service with respect  thereto,  the  most
recent  annual  reports  (Form  5500  and  the schedules thereto), the most
recent summary plan descriptions, and the most recent actuarial valuations.

     10.22 LABOR MATTERS.  TXEN is not a party to any collective bargaining
agreement relating to TXEN's employees.  TXEN  is  in all material respects
in compliance with all applicable laws respecting employment and employment
practices,   terms   and  conditions  of  employment,  wages   and   hours,
nondiscrimination in employment, and occupational health and safety, and is
not engaged in any unfair  labor practice.  Except as disclosed on Schedule
10.22,  there  are  no  pending  labor  grievances  or  sexual  harassment,
discrimination or other claims as to age, sex, religion, national origin or
physical  or  mental  disability,   civil   rights,   or  equal  employment
opportunity charges against TXEN relating to or involving employees, or any
settlements, consent orders, or prior decrees of any court  or governmental
body  requiring  any continued observance by TXEN relating to or  involving
employees.  No complaint  has  been  filed  or  is  pending or, to the best
knowledge  of  TXEN, threatened with the National Mediation  Board  or  the
National Labor Relations  Board  relating  to  or involving any employee of
TXEN alleging any unfair labor practices, and there  have not been any work
stoppages, strikes, or other significant labor troubles involving employees
of TXEN.

     10.23 EMPLOYEES; WAGE INCREASES.  Schedule 10.23 lists (i) all current
employees of TXEN, including those employees of TXEN currently  on  layoff,
disability  or  any  other  leave  ("Employees"),  including  their  names,
addresses,  ages,  current  rates  of  compensation and (ii) all employment
commitments  made by TXEN to persons other  than  the  Employees.   To  the
extent not set  forth  on  Schedule  10.17,  Schedule  10.23 also lists all
employment agreements with current Employees.  TXEN has  not,  with respect
to  Employees,  made  any  wage or salary increase other than the increases
already reflected on Schedule 10.23.

     10.24 NO PENDING OR THREATENED  LITIGATION  AND CLAIMS.  Except as set
forth on Schedule 10.24, TXEN is not a party to or,  to  the best knowledge
of  TXEN,  threatened  with  any  claim,  complaint, charge, suit,  action,
proceeding, hearing, arbitration, or other  method  of settling disputes or
disagreements, or any private or governmental investigation.   TXEN  is not
subject to any judgment, order, writ, injunction, stipulation, or decree of
any court, arbitrator, or governmental agency or instrumentality.

     10.25 ENVIRONMENTAL MATTERS.  To the best knowledge of TXEN, the  TXEN
business  as  presently conducted by TXEN complies with all applicable laws
and regulations  relating  to environmental protection, health, and safety,
including,  without  limitation,  laws  and  regulations  relating  to  the
generation,  transportation,   handling,   treatment,   storage,  disposal,
discharge, emission, release or threatened release of hazardous substances,
solid  waste,  hazardous  waste,  hazardous materials, asbestos  containing
materials,  petroleum  or  any  fraction  thereof,  pollutants,  irritants,
contaminants, toxic substances, or  any other materials defined as such in,
or regulated by, any such applicable  laws  and  regulations.   To the best
knowledge  of  TXEN, none of TXEN, its agents, their affiliates, and  prior
owners or users  of  the  properties  listed  on  Schedule  10.13 have ever
generated, stored, treated, transported, handled, disposed of, released, or
threatened to release, any regulated material in a manner that  could  give
rise  to  any liability on the part of the Surviving Corporation.  TXEN has
complied  with   the   reporting   requirements  concerning  the  disposal,

Except for  options issued in connection with the Option Plans, there is no
other  class  of  equity securities or instruments convertible into  equity
securities outstanding  (or  options,  warrants,  or  other rights granting
persons the right to acquire same or any TXEN Common Stock)  and  TXEN  has
not  issued  any bonds, debentures, or other evidences of indebtedness of a

TXEN to issue, transfer, assign or sell any additional shares of TXEN Stock
or authorize, create, issue or sell any other class of equity securities or

any stockholder agreement and consent to transactions contemplated hereby.

     10.37 SUBSIDIARIES.  TXEN has no subsidiaries.

     10.38 SECURITIES  MATTERS.   The  Shareholders  jointly  and severally
represent and warrant that they are acquiring their respective  portions of
NRC Common Stock for their own accounts, to hold for investment,  and  with
no intention of dividing their respective parts or their participation with
others, or reselling or otherwise participating, directly or indirectly, in
a distribution of the NRC Common Stock, and that each Shareholder shall not
make  any  sale,  transfer  or other disposition of the NRC Common Stock in
violation of the 1933 Act or the securities laws of any state.  Each of the
Shareholders have been advised  that  the  NRC  Common  Stock  is not being
registered  under  the  1933 Act on the grounds that such transactions  are
exempt from registration  under  one  or more exemptions under the 1933 Act
and also are not being registered under  any securities laws of the various
states on the grounds that such transactions  are  exempt from registration
thereunder, and that reliance by NRC on such exemptions  is  predicated, in
part, on the representation from the Shareholders set forth in this Section
10.38.   The Shareholders further understand that NRC is required  to  file
periodic reports  with  the  Securities  and  Exchange Commission and that,
following a one-year holding period, certain sales  of the NRC Common Stock
may be exempt from registration under the 1933 Act by  virtue  of Rule 144,
provided that such sales are made in accordance with all of the  terms  and
conditions  of  Rule  144,  including compliance with the required one-year
holding period.  It is understood  and  agreed  that  if  Rule  144  is not
available  for the sales of the NRC Common Stock, the NRC Common Stock  may
not be sold without registration under the 1933 Act or compliance with some
other exemption  from such registration, and, except as provided in Section
19 below, that NRC  is not obligated to register the NRC Common Stock to be
transferred pursuant  to  this Agreement or to take any action necessary in
order to make compliance with an exemption from registration available.  It
is  acknowledged  that  all  shares  of  NRC  Common  Stock  shall  bear  a
restrictive legend to the effect  that such shares have not been registered
and may not be sold or transferred  except pursuant to a registration or an
exemption therefrom.  The Shareholders acknowledge and agree that they have
not received any public solicitation  or  advertisement concerning an offer
to sell or to acquire the NRC Common Stock.

     10.39 AVAILABILITY OF INFORMATION.  TXEN  and  the  Shareholders  have
received  and  have  had an opportunity to review copies of NRC's Form 10-K
Report for the fiscal  year  ended August 31, 1996, Proxy Statement for the
1997 Annual Shareholders Meeting  and Annual Report to Shareholders for the
year ended August 31, 1996, and the  NRC  Quarterly  10-Q  Reports  for the
periods ended November 30, 1996, February 28, 1997, and May 31, 1997.  TXEN
and  the Shareholders have had an opportunity to meet with officers of  NRC
to discuss  the information contained in the above-referenced documents and
to receive answers  to  any  questions  they  had  regarding  NRC  and  the
acquisition  by  Shareholders  of  the  NRC  Common  Stock.   TXEN  and the
Shareholders  acknowledge  and  agree  that  they  are  not  relying on any
representations  and  warranties  (oral  or  written)  of  NRC or Surviving
Corporation   or  their  respective  officers,  directors,  employees   and
representatives,  except those representations and warranties expressly set
forth in this Agreement  and  the  matters  set  forth  in  the  Annual and
Quarterly  Reports  described in this Section.  Each individual Shareholder
for himself represents  and  warrants that he, individually or with the aid
of  an  investor representative  of  his  choice,  has  the  knowledge  and
experience  to  evaluate  the  merits and risks of accepting the NRC Common
Stock in exchange for their TXEN Common Stock.

stating  that  the  conditions  set  forth  in  this Section 13  have  been
fulfilled.

     SECTION 14.  DESIGNATIONS AND AGREEMENTS REQUIRED BY LAW

     As of the Effective Date, if NRC waives the  condition  set  forth  in
Section  12.12,  the Surviving Corporation agrees that it will promptly pay
to any dissenting  Shareholder  of  TXEN  the amount, if any, to which such
Shareholder shall be entitled under the laws of the State of Alabama.

                        SECTION 15.  ACCESS

     From  the  date  of  this  Agreement  to  the   Effective  Date,  each
Constituent Corporation shall provide the other with such  information  and
permit  each  other's  officers  and  representatives  such  access  to its
properties,  books  and  records  as  the  other  may,  from  time to time,
reasonably request.  Each Constituent Corporation shall inform the other of
materially  adverse events occurring after the date of this Agreement.   If
the Merger is  not  consummated,  all documents received in connection with
this Agreement shall be returned to the party furnishing such documents and
all information received shall be treated as confidential.

                     SECTION 16.  TERMINATION

     16.1 CIRCUMSTANCES OF TERMINATION.   This  Agreement may be terminated
(notwithstanding approval by the shareholders of either party):

          (a)  By the mutual consent in writing of  the  Board of Directors
     of each Constituent Corporation;

          (b)  By the Board of Directors of TXEN if any condition  provided
     in  Section  13  has  not  been  satisfied  or waived on or before the
     Effective Date;

          (c)  By  the  Board  of  Directors of NRC or  Subsidiary  if  any
     condition provided in Section 12  has  not been satisfied or waived on
     or before the Effective Date;

     16.2 EFFECT OF TERMINATION.  In the event  of  a  termination  of this
Agreement  pursuant  to  this  Section,  each party shall pay the costs and
expenses incurred by it in connection with  this Agreement and no party (or
any of its officers, directors and shareholders)  shall  be  liable  to any
other  party for any costs, expenses, damage or loss of anticipated profits
hereunder,   except   for   any  breach  by  a  party  or  parties  of  any
representations, warranties or covenants herein contained.

                     SECTION 17.  SURVIVAL OF
        REPRESENTATIONS AND WARRANTIES AND INDEMNIFICATION

     17.1 SURVIVAL.  The representations, warranties, and covenants made by
TXEN, Shareholders, Subsidiary  and  NRC in this Agreement will survive the
Closing Date and any investigation or  inquiry  made  by either party.  The
indemnifications  contained  in this Section 17 shall survive  the  Closing
until November 30, 1998.  No indemnified  party shall be entitled to assert
any claim for indemnification under this Section  17  with  respect  to the
breach  of  any representation, warranty or covenant contained herein after
the  date on which  such  representation  or  warranty  ceases  to  survive
pursuant to this Section 17.1.  If an indemnified party shall have notified
the indemnifying party of a claim for indemnification under this Section 17
prior  to the date on which the right of indemnification ceases to survive,
then the  indemnified party shall be entitled to prosecute the claim to its
completion and be entitled to indemnification hereunder.

     17.2 DEFINITION.    As   used   herein,   "Damages"   shall  mean  any
obligations,  losses,  liabilities,  security  interests,  liens,   claims,
encumbrances,  charges,  damages,  costs,  and expenses (including, without
limitation, attorneys' fees and other costs  and  expenses  incident to and
paid by an indemnified party in connection with the investigation, trial or
settlement of any claim, suit, action or proceedings) incurred, suffered or
sustained  or  paid  or  required  to  be  paid by an indemnified party  or
reasonably expected to be incurred by an indemnified  party.  Damages shall
be net of any insurance proceeds received by the indemnified party.

     17.3 INDEMNIFICATION BY SHAREHOLDERS.  After Closing, each Shareholder
agrees   to  and  shall  pay,  defend  and  promptly  indemnify   Surviving
Corporation  and  NRC  against, and save and hold Surviving Corporation and
NRC harmless from any and  all Damages resulting from, arising out of or in
connection with (a) any breach  or inaccuracy of any of the representations
and  warranties  made  by  TXEN and Shareholders  in  this  Agreement,  the
exhibits and schedules hereto,  and the certificates and documents executed
by them in connection herewith, (b)  the  breach  or non-fulfillment of any
agreement or covenant made by TXEN and Shareholders  in or pursuant to this
Agreement  and  the  transactions contemplated by this Agreement,  (c)  any
undisclosed liabilities  or obligations of TXEN and/or (d) any liability or
claim  or any threatened or  potential  liability  or  claim  disclosed  on
Schedules  10.15 and 10.24 hereto.  The liability of each Shareholder shall
be prorata based  on  the Merger Consideration received by such Shareholder
over the total Merger Consideration received by all Shareholders.

     17.4 INDEMNIFICATION  BY  SURVIVING  CORPORATION  AND  NRC.  Surviving
Corporation and NRC agree to jointly and severally pay, defend and promptly
indemnify the Shareholders against and save and hold them harmless from any
Damages resulting from, arising out of or in connection with (a) any breach
or  inaccuracy  of  any  of  the  representations  or  warranties  made  by
Subsidiary  or  NRC  in  this  Agreement  or  (b)  the breach of any of the
covenants made by Subsidiary or NRC in this Agreement.

     17.5 ALLOCATION OF DAMAGES.  Any Damages under  Section  17.3  may  be
recovered  either  by  Surviving  Corporation or NRC, as elected by NRC, or
such Damages may be allocated to NRC  and  Surviving Corporation as NRC, in
its sole discretion, may determine.

     17.6 NOTICE  OF  CLAIM.  Any party seeking  indemnification  hereunder
(the  "Indemnitee") shall  promptly  notify  the  indemnifying  party  (the
"Indemnitor")  in  writing,  of  any  claim  for  recovery,  specifying  in
reasonable  detail  the nature of the Damage, and, if known, the amount, or
an  estimate  of the amount,  of  the  liability  arising  therefrom.   The
Indemnitee shall  provide  to  the  Indemnitor  as  promptly as practicable
thereafter  information  and  documentation  reasonably  requested  by  the
Indemnitor to support and verify the claim asserted.

     17.7 DEFENSE OF THIRD PARTY CLAIMS.  If the facts pertaining  to  such
Damages  arise  out  of  the  claim  of any third party, the Indemnitor may
assume the defense thereof by written  notice  to Indemnitee, including the
employment of counsel or accountants at the Indemnitor's  cost and expense.
The Indemnitee shall have the right to employ counsel separate from counsel
employed  by the Indemnitor in any such action and to participate  therein,
but the fees  and expenses of such counsel employed by the Indemnitee shall
be at its expenses.   The Indemnitor shall not be liable for any settlement
of any such claim effected  without  its prior written consent, which shall
not be unreasonably withheld; provided  that  if  the  Indemnitor  does not
assume the defense or the prosecution of the claim within thirty (30)  days
of  notice  thereof,  the  Indemnitee  may  settle  such  claim without the
Indemnitor's  consent.  The Indemnitor shall not agree to a  settlement  of
any claim which  provides for any relief other than the payment of monetary
damages without the  Indemnitee's prior written consent, which shall not be
unreasonably withheld.   Whether or not the Indemnitor defends such claims,
all  the parties hereto shall  cooperate  in  the  defense  or  prosecution
thereof  and  shall  furnish  such  records, information and testimony, and
attend  such  conferences,  discovery  proceedings,  hearings,  trials  and
appeals, as may be reasonably requested in connection therewith.

     17.8 REDUCTION  FOR INSURANCE AND TAX  BENEFITS.   The  Damages  which
Indemnitor is liable to,  for  or  on  behalf of the Indemnitee pursuant to
this   Section  17  shall  be  reduced  (including,   without   limitation,
retroactively)  through  subsequent  repayment  as  described below in this
Section 17.8, by an amount equal to any insurance proceeds and tax benefits
actually  recovered  by  or on behalf of such Indemnitee  relating  to  the
Damages.  If an Indemnitee  shall  have  received or shall have paid on its
behalf  an  indemnity  payment  in respect of  any  Damages  and  insurance
proceeds and tax benefits in respect  of such  Damages are also received by
the Indemnitee, then such Indemnitee shall  pay  Indemnitor  the  amount of
such  insurance  proceeds and tax benefits or, if less, the amount of  such
indemnity  payment.   The  Indemnitee  covenants  and  agrees  to  use  all
reasonable efforts  to  collect  all such sums as are available to it under
its existing insurance policies which  would  be  applicable  to  any  such
Damages.   Whether  or  not  Indemnitee  receives  any tax benefit shall be
determined by Ernst & Young, L.L.P.

     17.9 DEDUCTIBLE.  An indemnified party shall make no claim against any
indemnifying  party for indemnification under this Section  17  unless  and
until the aggregate  amount  of  such claims against the indemnifying party
exceeds $200,000.00 (the "Deductible"), in which event an indemnified party
may claim indemnification for all Damages in excess of the Deductible.

     17.10 LIMITATIONS.  The amount  of indemnification either party may be
entitled hereto shall not exceed $4,387,497.19 unless such claims are based
on pending or threatened (in writing)  litigation, in which case the amount
of  indemnification will not exceed $10,968,742.98.   The  limitations  set
forth herein shall not apply in the case of fraud.

     17.11  ARBITRATION.   The parties agree that any claim, controversy or
dispute arising out of or relating  in  any  way  to  this Agreement or the
formation, interpretation, performance, enforcement, breach, termination or
validity thereof, including the construction and scope  of the agreement to
arbitrate  shall be resolved in accordance with the provisions  of  Exhibit
"I."

           SECTION 18.  CERTAIN COVENANTS OF THE PARTIES
                    WITH RESPECT TO TAX MATTERS

     18.1 TAX  RECORDS.   TXEN will provide to NRC and Subsidiary copies of
all its Tax Returns and other  Tax  related matters between the date of the
execution of this Agreement and the Effective  Date and will provide copies
to NRC and Subsidiary of all records and information  which may be relevant
to such returns and matters and will retain such records  and  information.
Any   information   obtained   pursuant  to  this  Section  shall  be  kept
confidential by the parties hereto.

     18.2 TXEN FINAL TAX RETURN.   The  Surviving  Corporation agrees that,
before  filing  TXEN's  federal  income tax return for any  taxable  period
ending on or before the Effective  Date, including, without limitation, the
information return of TXEN for the partial  tax  year  of TXEN ended on the
Effective Date, they will obtain Shareholder Representative's  approval and
consent  (which approval and consent shall not be unreasonably withheld  or
delayed) for  all  items  of  income  and  deduction  shown  thereon.   The
Surviving  Corporation  will cause the federal and state income tax returns
of TXEN for the period ending the day before the Effective Date to be filed
with the Internal Revenue Service and state authorities.

    SECTION 19.  PIGGYBACK REGISTRATION RIGHTS OF SHAREHOLDERS

     19.1 IN  GENERAL.  The  rights  provided  for  in  this  section  (the
"Piggyback Rights")  shall apply to those TXEN Shareholders who receive NRC
Common Stock in exchange  for  their  TXEN  Common  Stock  pursuant to this
Agreement.  As used in this section, the term "NRC Common Stock" shall mean
the  par value $0.01 per share common stock of NRC outstanding  as  of  the
date of the execution of this Agreement and shall not include any preferred
stock  or  other  special  class  of stock that may be registered under the
Securities Act of 1933 (the "Act").   If  (but without any obligation to do
so)  NRC  proposes  to  register any NRC Common  Stock  under  the  Act  in
connection with the public  offering  of  such  NRC Common Stock solely for
cash (other than a registration relating solely to  the  sale of securities
to employees of NRC pursuant to a stock option, stock purchase  or  similar
plan, relating to a Rule 145 transaction, relating to a merger or other NRC
acquisition,  or  a  registration  on  any  form  which  does  not  include
substantially the same information as would be required to be included in a
registration  statement covering the sale of the NRC Common Stock owned  by
the Shareholders),  NRC shall, at such time, promptly give each Shareholder
who owns NRC Common Stock  pursuant  to  an  exchange  for  his or her TXEN
Common  Stock  under  this  Agreement  written notice of such registration.
Upon NRC's receipt of the written request  of  each  such Shareholder given
within 20 days after NRC's mailing of such notice, NRC  shall,  subject  to
the  other provisions of this section, cause to be registered under the Act
all of  the NRC Common Stock that each such Shareholder has requested to be
registered,  provided, however, that each such Shareholder may only request
registration for  those shares of NRC Common Stock acquired in exchange for
TXEN  Common  Stock  pursuant   to   this   Agreement   (the  "Registerable
Securities").   NRC  shall  pay all costs for registering the  Registerable
Securities.  When required under  the  terms  of this section to effect the
registration of the Registerable Securities, NRC shall, as expeditiously as
reasonably possible:

          (a)  prepare and file with the Securities and Exchange Commission
     (the  "Commission")  a registration statement  with  respect  to  such
     Registerable Securities  and  use  its  best  efforts  to  cause  such
     registration statement to become effective.

          (b)  prepare  and  file  with  the Commission such amendments 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 Act with respect to the disposition
     of all securities covered by such registration statement.

          (c)  furnish  to  the  Shareholders who acquired NRC Common Stock
     pursuant to this Agreement such  number  of  copies  of  a prospectus,
     including   a   preliminary   prospectus,   in   conformity  with  the
     requirements  of  the  Act,  and  such  other documents  as  they  may
     reasonably  request in order to facilitate  the  distribution  of  the
     Registerable Securities owned by them.

          (d)  use  its best efforts to register and qualify the securities
     covered by such  registration statement under such other securities or
     Blue Sky Laws of such  jurisdictions  as shall be reasonably requested
     by  the  underwriters, provided, however,  that  the  holders  of  the
     Registerable  Securities shall not be allowed to cause NRC to register
     and qualify the  Registerable Securities under any particular security
     or Blue Sky Law of any particular state or jurisdiction.

          (e)  in the event of any underwritten public offering, enter into
     and perform its obligations under an underwriting agreement with terms
     generally satisfactory  to  the managing underwriter of such offering.
     Each   holder  of  Registerable  Securities   participating   in   the
     underwriting  shall  also enter into and perform his or her respective
     obligations, as reasonably  requested  by  the  managing  underwriter,
     under such an agreement.

It shall be a condition precedent to the obligations of NRC to register the
Registerable  Securities  that  the  holders of the Registerable Securities
shall   furnish  to  NRC  such  information   regarding   themselves,   the
Registerable   Securities   held  by  them,  and  the  intended  method  of
disposition of such Registerable  Securities as shall be required to effect
the registration of such Registerable  Securities.   Notwithstanding any of
the  foregoing,  NRC  shall  have  the  right,  in its sole discretion,  to
terminate  the  registration  of  the  Registerable  Securities   and   the
registration  of  the  other NRC Common Stock which triggered the Piggyback
Rights if, at such time,  the  underwriters  are  of  the  opinion  that  a
registration  at  such  time would not be advisable, or if there has been a
material adverse change in  the  condition, business or prospects of NRC or
if, for any good and sufficient reason,  NRC  determines  to  terminate the
registration causing the existence of the Piggyback Rights.

     19.2 EXPENSES,  LIMITATIONS  AND  AGREEMENTS.   The  holders  of   the
Registerable  Securities  must  bear  and  pay their prorata portion of any
underwriting discounts and commissions.  In  connection  with  any offering
involving an underwriting, NRC shall not be required to include  any of the
holders of Registerable Securities in such underwriting unless such holders
accept  the  terms  of the underwriting as agreed upon between NRC and  the
underwriters selected  by  NRC, and then only in such quantity as will not,
in the opinion of the underwriters,  jeopardize the success of the offering
by NRC or the NRC shareholders demanding  such  registration.  If the total
amount  of  Registerable  Securities that all Shareholders  with  Piggyback
Rights under this section request  to  be included in such offering exceeds
(when  combined with the securities being  offered  by  NRC  or  its  other
shareholders)  the  amount  of  securities that the underwriters reasonably
believe compatible with the success  of  the  offering,  then  NRC shall be
required  to  include  in  the  offering  only  that number of Registerable
Securities which the underwriters believe will not  jeopardize  the success
of  the  offering  and  the  Registerable  Securities so included shall  be
apportioned,  prorata,  among the Shareholders  in  accordance  with  their
respective ownership percentages or in such other proportions as they shall
mutually  agree.   The  definitive  agreements  shall  contain  such  other
provisions as the parties  may  require  and  agree  in connection with the
Piggyback  Rights,  to  include  provisions requiring the  Shareholders  to
indemnify NRC or any underwriter in connection with any untrue statement of
material fact or the omission to state  material facts committed or omitted
by the Shareholders in connection with the offering.

     19.3 NO ASSIGNMENT OF PIGGYBACK RIGHTS.   The Piggyback Rights may not
be assigned by a Shareholder owning Registerable  Securities to any person,
executor,   personal   representative,  transferee  or  assignee   of   the
Registerable Securities owned by the Shareholder.

     19.4 TRANSFER  RESTRICTION.   Each  Shareholder  exercising  Piggyback
Rights will agree that  he  or she will not, to the extent requested by NRC
and/or any underwriter, sell,  make  any  short  sale  of,  loan, grant any
option  for  the  purchase of or otherwise transfer or dispose of  any  NRC
Common Stock (including  the  Registerable  Securities)  without  the prior
written consent of NRC and/or such underwriter, as the case may be,  during
the  180  day  period  following  the  effective  date  of the Registration
Statement  of NRC filed under the Act.  In order to enforce  the  foregoing
covenant, NRC  may  impose  stop-transfer  instructions with respect to the
Registerable Securities until the end of such 180 day period.

     19.5 TERMINATION.  These Piggyback Rights  under  this  Section  shall
terminate  one year after the Effective Date and thereafter, no Shareholder
shall have any  right  to  require  registration  of  his or her NRC Common
Stock.

                SECTION 20.  POST CLOSING COVENANTS

     After the Closing, NRC and Subsidiary covenant as follows:

     (a)  Any key employee term life insurance policies owned by TXEN where
TXEN was named beneficiary insuring the Shareholders shall  be  distributed
to the insured.

     (b)  Stock options covering 30,000 shares of NRC Common Stock  will be
reserved  for issuance under the NRC Stock Option Plan to employees of  the
Subsidiary  as  recommended  by Thomas L. Patterson, and as approved by the
NRC Stock Option Committee.

     (c)   The 401(k) Plan of  TXEN  shall continue to be maintained by the
Subsidiary after the Closing, provided  that Subsidiary may maintain such a
separate plan under applicable provisions of the Internal Revenue Code as a
member of a controlled group of corporations  and  that maintenance of such
separate plan will not disqualify the 401(k) Plan maintained  by NRC or the
401(k) Plan maintained by Subsidiary under the qualification provisions  of
the Internal Revenue Code or ERISA.  Nothing contained herein shall require
NRC  to  amend  or  terminate  its  qualified  retirement  plan in order to
maintain the separate existence of the 401(k) Plan of TXEN.

                  SECTION 21.  GENERAL PROVISIONS

     21.1 FURTHER ASSURANCES.  At any time, and from time to  time,  before
and  after  the  Effective  Date,  each  party will execute such additional
instruments  and  documents  and  take such action  as  may  be  reasonably
requested by any other party to confirm  or  perfect  title to any property
transferred hereunder or otherwise to carry out the intent  and purposes of
this Agreement.

     21.2 WAIVER.  Any failure on the part of any party to comply  with any
of  its  obligations,  agreements or conditions hereunder may be waived  in
writing by any other party.

finder has acted for it in connection with this  Agreement  and  agrees  to
indemnify  and  hold  harmless  the  other parties against any fee, loss or
expense arising out of claims by brokers or finders.

     21.4 NOTICES.  All notices and other communications hereunder shall be

of NRC.

     21.8 COUNTERPARTS.   This  Agreement may be executed simultaneously in
two or more counterparts, each of  which  shall  be deemed an original, but
all of which together shall constitute one and the same instrument.

     21.9 INTERPRETATION AND CONSTRUCTION.  Each party  to  this  Agreement
acknowledges and agrees that it and he is sophisticated in business matters
and  has  been  represented,  at  all  times, by counsel of its and his own

require ambiguities in this Agreement to be resolved against the party that
has drafted this Agreement shall not be applicable and is waived.

     21.10 SHAREHOLDER REPRESENTATIVE.   The  Shareholders hereby elect and
appoint Thomas L. Patterson as the Shareholder  Representative and vest him
with  the full power and authority, as agent and attorney-in-fact  for  the
Shareholders,  to  communicate  and  receive  all notices, to give notices,
counter notices, joint written instructions and  make  payments  and  other
communications  on  behalf  of  the  Shareholders,  and to make agreements,
compromises, waivers and settlements with respect to this Agreement and the
Escrow Agreement executed herewith and to resolve all  disputes  under this
Agreement.   Thomas  L. Patterson shall serve as Shareholder Representative
until NRC receives written  notice from Shareholders who held, prior to the
Effective Date, more than 50%  of  the  outstanding TXEN Common Stock, that
another Shareholder has been named as the  Shareholder Representative.  The
appointment of Thomas L. Patterson as Shareholder  Representative  shall be
considered a durable power of attorney, a power of attorney coupled with an
interest and to the extent permitted by law shall survive the incapacity of

by the other Shareholders.

     21.11 CORPORATE POLICIES, ETC.   All  corporate acts, plans, policies,
approvals  and  authorizations  of  TXEN  which were  valid  and  effective

and  shall  be  as  effective  and  binding  thereon as they were on  TXEN.
Without limiting the foregoing, all welfare benefit  plans, salaries of the
employees  of TXEN, employment policies, and sales and  other  policies  in
effect  immediately  prior  to  the  Merger   shall  be  continued  by  the
Subsidiary,  except  to  the extent such employees become employees of NRC.
This Section shall not prevent  the  Board  of Directors or officers of the
Subsidiary  from  amending  or  termination  such  acts,  plans,  policies,
approvals and authorizations after the Effective Date.  This Section is not
intended to benefit any employee of TXEN or any other third party.

     21.12  SEVERABILITY.   In the event any provision  contained  in  this
