ITEM 2.       ACQUISITION OR DISPOSITION OF ASSETS.

       On August 27, 1997, Nichols Research Corporation ("Nichols Research"), a
Delaware corporation, entered  into an Agreement of Merger (the "Agreement") to
acquire all of the issued and outstanding  capital  stock  of  TXEN,  Inc.,  an
Alabama  corporation  ("TXEN"),  from the shareholders of TXEN pursuant to that
Agreement.  The closing of the transaction  took  place on August 29, 1997, and
the merger became effective on August 31, 1997.

       Before August 31, 1997, Nichols Research owned  999,500  shares  of  the
Class  B  Common  Stock  of TXEN.  These shares represented 100% of the Class B
Common Stock outstanding and  19.9%  of  all of the Common Stock of TXEN, Inc.,
outstanding.   The other outstanding Common  Stock  of  TXEN  was  composed  of
4,000,500 shares of Class A Common Stock.

       Pursuant  to  the Agreement, effective August 31, 1997, TXEN merged into
Nichols Select Corporation  (the  "Subsidiary"),  a  Delaware corporation and a
wholly owned subsidiary of Nichols Research.  As a result  of  the  merger, the
Class   B  Common  Stock  owned  by  Nichols  Research  was  cancelled  without
consideration.   Further,  the  Class  A Common Stock of TXEN was exchanged for
1,084,148 shares of Nichols Research's $.01  par  value  Common Stock valued at
approximately $26.3 million and $17,550,265.13 in cash.  The purchase price was
allocated among the Class A shareholders of TXEN in accordance  with  each such
shareholder's  interest  in  TXEN.   The  specific  number of shares of Nichols
Research  Common  Stock  delivered  to the TXEN shareholders  pursuant  to  the
Agreement was determined by negotiations  between  the  parties, and not by any
formula  or  other objective method.  The purchase price was  determined  by  a
formula contained  in  a  Stock Purchase Option Agreement dated December, 1994,
and an amendment to that Option  Agreement  dated  July  1996,  between Nichols
Research,  TXEN and the shareholders of TXEN.  The purchase price  formula  was
77 1/2 % of  Nichols  Research's  average price to earnings ratios for the four
months ended June 30, 1997, multiplied by TXEN's net after-tax earnings for its
fiscal year ended June 30, 1997.  This  purchase price formula contained in the
Option Agreement and amendment thereto was  determined  by negotiations between
the parties.

       Chris H. Horgen, Chief Executive Officer and Chairman  of  the  Board of
Nichols  Research,  owned 245,000 shares of TXEN Class A Common Stock prior  to
the merger.  Pursuant  to the merger, Mr. Horgen received $2,687,006.15 in cash
and received no Nichols Research Common Stock.

       At closing, Nichols  Research,  the  Subsidiary  and the shareholders of
TXEN also entered into an Escrow Agreement.  From the cash paid at closing, the
TXEN  shareholders  placed $877,513.26 in escrow until September  1,  1998,  to
apply against any indemnification  obligations  that  arise under the Agreement
before the escrow termination date.

       The Agreement provides that in the event Nichols  Research determines to
file  a registration statement registering any of its Common  Stock  under  the
Securities Act of 1933, then Nichols Research will permit the TXEN shareholders
to include  their  shares  in  that  offering  and  registration statement upon
meeting certain conditions.

       At  closing, Thomas L. Patterson amended his Employment  Agreement  with
the Subsidiary.   Pursuant  to  that  amended  Employment  Agreement, Thomas L.
Patterson will continue to serve as President of the Subsidiary  for  a two (2)
year  term.   In addition to provisions governing the salary to be paid to  Mr.
Patterson, the  Employment Agreement contains provisions concerning payments to
be paid by the Subsidiary  in  the  event  of  the  employee's  termination  of
employment  with  the  Subsidiary.   The  Employment  Agreement also contains a
covenant not to compete, a nonsolicitation agreement and  an  agreement  not to
disclose confidential information of the Subsidiary.

       Some  of  the  cash  used  to acquire the TXEN shares came from existing
reserves  and  some  of the cash was borrowed  by  Nichols  Research  under  an
existing credit agreement between Nichols Research, SouthTrust Bank of Alabama,
N.A., First Alabama Bank, and Corestates Bank, N.A.

       The 1,084,148 shares  of Nichols Research Common Stock owned by the TXEN
shareholders represent approximately 8.37% of the Nichols Research Common Stock
issued and outstanding.

       As a result of the merger,  Nichols  Research currently owns 100% of the
outstanding  shares  of  the Subsidiary.  The Subsidiary  provides  information
technology products and services  to the managed healthcare industry, including
computerized claims processing and administration services.

       For additional information regarding the Agreement, the Escrow Agreement
and the amended Employment Agreement,  please  refer  to  the  copies  of those
documents  which  are incorporated herein by reference and included as Exhibits
to this Current Report  on  Form 8-K.  The foregoing discussion is qualified in

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

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

                     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
resale limitations.

            SECTION 6.  BOARD OF DIRECTORS AND OFFICERS

     On the Effective Date, the members of the  Board  of  Directors of the
Surviving Corporation shall be Thomas L. Patterson, Chris H.  Horgen, Allen
E. Dillard and Patsy L. Hattox.

                   SECTION 7.  EFFECT OF MERGER

     On the Effective Date, the separate existence of TXEN shall  cease and
it  shall  be  merged  with  and  into  the  Surviving Corporation.  On the
Effective Date, all the rights, privileges, powers  and  franchises of each
of the Constituent Corporations, both of a public and private  nature,  all
property,  real,  personal,  and  mixed,  all debts due on account, and all
other things in action and all intangible assets  belonging  to each of the
Constituent  Corporations  and  all  and  every  other  interests shall  be
transferred to and vested in the Surviving Corporation, without further act
or  deed, as effectually as they were vested in the respective  Constituent
Corporations;  and  the  title  to  any property, whether vested by deed or
otherwise, in either of the Constituent Corporations shall not revert or be
in any way impaired by reason of the  Merger.   The  Surviving  Corporation
shall  thereafter  be  responsible for all debts, liabilities, obligations,
restrictions,  disabilities   and   duties   of  each  of  the  Constituent
Corporations  and all said debts, liabilities,  obligations,  restrictions,
disabilities  and   duties   shall   thereafter  attach  to  the  Surviving
Corporation and may be enforced against  it  to  the same extent as if they
had  been  incurred  or  contracted  by  it,  but the liabilities  of  each
Constituent  Corporation  or of its stockholders,  directors,  or  officers
shall  not  be  affected,  nor  shall  the  rights  of  creditors  of  each
Constituent Corporation or of  any  person  dealing with either Constituent
Corporation  or  any  liens  upon  the  property  of   either   Constituent
Corporation be impaired by the Merger and any action or proceeding  pending
by  or  against  either  of  the Constituent Corporations may be carried to
judgment the same as if the Merger  had  not  taken  place,  which judgment
shall bind the Surviving Corporation, or the Surviving Corporation  may  be
proceeded  against  or  substituted  in  its place.  In accordance with the
provisions of this Agreement, the General  Corporation  Law of the State of
Delaware and the Alabama Business Corporation Act, at the  Effective  Date,
TXEN  shall  be  merged  with  and  into Subsidiary, with Subsidiary as the
Surviving Corporation, and the Surviving  Corporation  shall  be  a  wholly
owned  subsidiary  of NRC, but shall continue its corporate existence under
the laws of the State  of  Delaware.   The  separate corporate existence of
TXEN shall terminate at the Effective Date.

               SECTION 8.  APPROVAL OF SHAREHOLDERS

     This Agreement, the Certificate of Merger  and  the Articles of Merger
have been approved by the shareholders of each Constituent  Corporation  as
provided  by  Section  228  of the General Corporation Laws of the State of

However,  it  shall  be  a  condition to the  Closing  of  the  transaction

     10.13 REAL PROPERTY.

          (a)  TXEN  owns  no fee  simple  interest  in  real  property  or
     easement rights.  Except as disclosed on Schedule 10.13, TXEN does not
     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.

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.

     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,
discharge,  emission,  spillage,  release  or  threatened  release  of  any
hazardous  substance  with respect to  such  properties.   TXEN  is  not  a
"potentially  responsible   party,"   as   defined   in  the  Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended,
or under any comparable state or local statute, in connection with any past
or present waste disposal practices undertaken by it or on its behalf.

     10.26   CUSTOMERS.   Schedule  10.26  identifies  all  customers   who
purchased any  product or service manufactured, licensed, sold, or provided
by TXEN since June  30,  1994.   TXEN  is  not  aware  of  any  existing or
anticipated  changes  in  the  purchasing  policies  or  practices of these
customers,  or  in  their  financial  condition,  that might reasonably  be
expected  to  have  a material adverse effect on future  orders  of  TXEN's
business.

     10.27 SUPPLIERS.   Schedule  10.27 is a list of all material suppliers
of materials and services to TXEN since June 30, 1994.  Except as listed on
Schedule 10.27, no supplier represents  TXEN's  sole  source of any type or
types of supplies.  Except as set forth in Schedule 10.27,  no supplier has
materially increased its prices as applicable to the products  purchased by
TXEN since June 30, 1994 and TXEN has not received notice of any such price
increase.  TXEN is not aware of any existing or anticipated changes  in the
policies  or practices of these suppliers, or in their financial condition,
that might  reasonably be expected to have a material adverse effect on the
Surviving Corporation's ability to obtain supplies from these suppliers.

     10.28 INSURANCE.   Schedule  10.28  identifies all of TXEN's insurance
policies and bonds (the "Insurance Policies").   The Insurance Policies are
in full force and effect; are sufficient for compliance  by  TXEN  with all
requirements  of law and of all agreements to which it is a party; and  are
valid, outstanding,  and  enforceable  policies  and provide that they will
remain in full force and effect through the Effective Date.

     10.29  PRODUCT  SPECIFICATIONS.  To the best knowledge  of  TXEN,  all
products manufactured,  developed,  licensed  and/or  distributed  by  TXEN
comply with the specifications and other criteria contained in the product,
sales,  and  marketing  literature  and other documentation used by TXEN in
connection with the sale or marketing  of  TXEN's products and services and
in any applicable customer specifications.

     10.30 ACCOUNTS RECEIVABLE.  All outstanding  accounts  receivable  and
notes  receivable of TXEN are bona fide receivables, arose in the usual and
ordinary course of business, are due and valid claims against customers for
goods  delivered   or   services   performed,  subject  to  no  offsets  or
counterclaims, and are fully collectable,  net  of the reserve for doubtful
accounts  shown on the Financial Statements of TXEN  described  in  Section
10.7.

     10.31 DISCLOSURE.  To the best knowledge of TXEN, no representation or
warranty by  TXEN  and Shareholders in this Agreement, nor any schedules or
exhibits to this Agreement nor any statement or certificate furnished or to
be furnished to NRC  or  Surviving  Corporation pursuant to this Agreement,
contains or will contain any untrue statement of a material fact or omit or
will  omit  to  state  a material fact necessary  to  make  the  statements
contained therein not misleading.  TXEN and the Shareholders do not know of
any  facts or conditions  relating  to  the  TXEN  business  which  have  a
reasonably likelihood of materially adversely affecting the TXEN business.

     10.32  ACCOUNTS.  Schedule 10.32 sets forth the names and locations of
all banks and  other  institutions  in  which  TXEN  has an account or safe
deposit box and the names of all persons authorized to  draw  thereon or to
have  access thereto.  Schedule 10.32 also sets forth the balance  in  each
checking, savings or other deposit account of TXEN as of June 30, 1997.

     10.33  TRANSACTIONS  WITH  RELATED  PARTIES.   Except  as disclosed on
Schedule 10.33, no Shareholder, officer, director, or employee  of TXEN, or
any corporation or other entity controlled by or under common control  with
any of the foregoing and no relative of any of the foregoing has:

          (a)  borrowed  money  from  or loaned money to TXEN which remains
     outstanding  (excluding travel advances  in  the  ordinary  course  of
     business and consistent with past practice);

          (b)  any  contractual  or other claim (except for compensation as
     disclosed in the schedules to this Agreement) expressed or implied, of
     any kind whatsoever against TXEN;

          (c)  any interest in any  business,  assets or properties of TXEN
     (whether ownership, contractual or otherwise); or

          (d)  engaged  in  any other transaction  with  TXEN  (other  than
     employment relationships)  since the date of TXEN's incorporation, not
     otherwise reflected on the Financial  Statements  described in Section
     10.7.

     10.34 FINDERS.  No finder or broker has acted or is  acting  on behalf
of TXEN in connection with the transactions contemplated by this Agreement.

     10.35  SURVIVING CORPORATION'S ABILITY TO OPERATE THE BUSINESS.   Upon
the Effective Date, Surviving Corporation shall have received from TXEN all
the  property,   equipment,  inventory,  contracts,  permits,  intellectual
property, leasehold  interests,  books  and records, hardware and software,
and other assets and rights necessary for  Surviving Corporation to conduct
TXEN's business as the same is presently conducted by TXEN.

     10.36 CAPITALIZATION.  TXEN's authorized  capital  consists of 1 share
of  Convertible  Preferred  Stock,  par  value  of  $.002  per  share  (the
"Preferred  Stock"),  5,000,000  shares of Class A Common Stock of the  par
value of $.002 per share (the "Class  A Common Stock") and 1,250,000 shares
of Class B Common Stock of the par value  of  $.002 per share (the "Class B
Common Stock").  The issued and outstanding shares  of  TXEN Stock are held
by those individuals and entities in those amounts shown  in  Section 10.1.
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
similar nature.   From  the  date of the execution of this Agreement to the
Effective Date, TXEN agrees not  to and the Shareholders agree not to cause
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
bonds, debentures or instruments of a similar nature, and further agree not
to execute any options, warrants or  other  rights to acquire TXEN stock or
any  additional  rights.   All of the shares of  TXEN  Stock  held  by  the
Shareholders are free and clear  of  all  liens,  claims, pledges, options,
rights, security interests and encumbrances, except  as provided in Section
5.6(d)  hereof.   All  outstanding  shares  of  TXEN stock have  been  duly
authorized  and  issued  and are fully paid and nonassessable.   Except  as
described  on Schedule 10.36,  there  are  no  agreements  restricting  the
transfer of  TXEN  stock  or  granting  any options, agreements, contracts,
cause or commitments of any character which  would restrict the transfer or
issuance  of any TXEN stock or which would require  the  issuance  of  TXEN
stock, or which would require TXEN to purchase or redeem any shares of TXEN
stock.  By  executing this Agreement, Shareholders, waive all provisions of
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.

     10.40 LIMITED REPRESENTATIONS  AND  WARRANTIES OF THE UNIVERSITY.  The

the transactions contemplated hereby or thereby.

          10.40.5  ESTOPPEL PROVISIONS.   As  of  the  Closing Date and the

                     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

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

                         ESCROW AGREEMENT

     THIS  ESCROW AGREEMENT dated the 29th day of August, 1997 (the "Escrow
Agreement"),  is among Nichols Research Corporation, a Delaware corporation
("NRC"); NRC's  wholly  owned  subsidiary,  Nichols  SELECT  Corporation, a
Delaware   corporation  ("SELECT")  TXEN,  Inc.,  an  Alabama  corporation,
("TXEN"); the  holders  of all of the $0.002 par value Class A Common Stock
of  TXEN (the "Shareholders");  and  SouthTrust  Bank,  N.A.  (the  "Escrow
Agent").

                         W I T N E S E T H

     Pursuant  to  that  certain Agreement of Merger dated August 27, 1997,
(the "Merger Agreement"),  TXEN has agreed to merge into SELECT with SELECT
as  the  surviving  corporation.   Capitalized  terms  used  herein  unless
otherwise defined shall  have  the  meaning  ascribed  to such terms in the
Merger  Agreement.  Pursuant to Section 17.3 of the Merger  Agreement,  the
Shareholders  have  agreed to indemnify NRC and SELECT and have agreed that
the assets deposited  pursuant  to  this  Escrow Agreement shall secure the
indemnification obligations.

     Therefore, pursuant to the Merger Agreement  and  in  consideration of
the  mutual  covenants hereinafter contained, the parties hereby  agree  as
follows:

     SECTION 1. On even date herewith, Shareholders have deposited with the
Escrow Agent the  sum  of Eight Hundred Seventy Seven Thousand Five Hundred
Thirteen and Twenty-Six  cents  ($877,513.26)  (the  "Escrow   Money")  and
54,208  shares  of  NRC Common Stock (the "Escrow Stock).  The Escrow Money
and the Escrow Stock  (collectively the "Escrow Fund") shall be held by the
Escrow  Agent  hereunder   as  partial  security  for  the  performance  by
Shareholders of their indemnification obligations set forth in Section 17.3
of the Merger Agreement.

     SECTION 2. The Escrow Fund  and  any interest thereon shall be held by
the Escrow Agent for the account of the  Shareholders,  subject  to written
instruction signed jointly by NRC and Shareholders or as otherwise provided
herein.

     SECTION 3. (a) At anytime on or prior to the Escrow Termination  Date,
as  hereafter  defined,  with respect to the Escrow Fund, NRC or SELECT may
give written notice (the "Initial  Notice")  to Shareholders and the Escrow
Agent of a claim (a "Claim") for indemnification resulting from any Damages
(as defined in the Merger Agreement) suffered, sustained or incurred by NRC
or  SELECT or that may reasonably be expected to  be  suffered  by  NRC  or
SELECT  as  a result of any matters made the subject of Section 17.3 of the
Merger Agreement  or otherwise arising out of the transactions contemplated
by and made the subject  of  the  Merger  Agreement.   If  the Shareholders
dispute  such  Claim,  the Shareholders shall send written notice  to  NRC,
SELECT and the Escrow Agent  that such Claim is disputed within twenty (20)
days after Shareholders are deemed  to  have received the Initial Notice (a
"Counter Notice").  Thereafter, except as  provided  in  the next sentence,
the  Escrow  Agent  shall  not deliver any of the Escrow Fund  or  interest
thereon made the subject of  the  Claim  to  NRC,  SELECT  or Shareholders,
except upon joint written instructions of NRC, SELECT and Shareholders.  As
an  alternative to joint written instructions, NRC, SELECT or  Shareholders
may give  a  notice  (a  "Claim  Notice") to the other party and the Escrow
Agent to the effect that a Claim on  all  or  part  of the Escrow Fund (and
accrued interest thereon) has been resolved, which notice  shall  set forth
the amount of the Claim to be delivered to NRC, SELECT or Shareholders,  if
any, and shall have appended a copy of a judicial order, judgment or decree
which  evidences  a resolution of the Claim, including a certification that
neither party has filed  an  appeal or that any appeal which has been filed
has been finally resolved.

               (b)  Upon receipt  of  the  Claim  Notice with all necessary
attachments,  or  upon  receipt of joint written instructions,  the  Escrow
Agent shall promptly deliver  to NRC, SELECT or Shareholders the amount due
such party as set forth in the Claim Notice, if any, or the amount due such
party as set forth in the joint written instructions.

               (c)  NRC or SELECT  may  file Claims on both the Escrow Fund
and  any  interest thereon, less disbursement  made  of  net  income  under
Section 4 hereof.   If  a Claim on less than all of the Escrow Fund and any
interest thereon is filed  and  all or any part of such Claim is ultimately
paid  to  NRC or SELECT, then, in addition  to  the  amount  of  the  Claim
required to  be  paid  to  NRC  or  SELECT  as  a  result  of joint written
instructions or a Claim Notice, the Escrow Agent shall pay to  NRC,  out of
any  remaining  Escrow Fund and any interest thereon, an amount of interest
equal to the interest allocable to the amount of the Claim actually paid to
NRC or SELECT from the date of the Initial Notice until the date all or any
part of the Claim  is  paid  to  NRC, less disbursements made of net income
under Section 4 hereof.

               (d)  With respect to all  amounts held in the Escrow Account
(and  the  interest thereon), the Escrow  Termination  Date  shall  be  the
earlier of:

                    (i)  September 1, 1998, or

                    (ii) the  date  the  Escrow  Agent  no longer holds any
                         funds hereunder as a result of prior Claims, joint
                         written instructions or Claim Notices.

On  the  Escrow  Termination  Date,  the  Escrow  Agent  shall deliver  any
remaining  Escrow  Fund,  including  any  accrued  interest  thereon,  less
disbursements   of   net  income  made  under  Section  4  hereof,  to  the
Representative, unless  an  Initial  Notice,  Claim,  or  Claim  Notice  is
pending,  in  any of which cases the amount claimed, together with interest
on the amount claimed  from  the  date  of the Initial Notice to the Escrow
Termination Date, shall be retained by the  Escrow Agent until a resolution
of such pending Claims.  Upon final resolution  of  the  pending Claims and
disbursements  of  the amounts retained by the Escrow Agent  in  accordance
with Claim Notices or  joint  written  instructions,  this Escrow Agreement
shall  terminate.  All assets distributed by Escrow Agent  to  Shareholders
hereunder shall be distributed to the Representative for the benefit of the
Shareholders.   It  shall  be  the  responsibility of the Representative to
distribute to each Shareholder his portion  of  the assets distributed from
the Escrow Account in accordance with the Merger  Consideration  Allocation
in EXHIBIT "C" of the Merger Agreement.

               (e)  The  Representative  of  the Shareholders appointed  in
Section 21.10 of the Merger Agreement is authorized (i) to take all actions
permitted  hereunder  by  the Shareholders, including  joint  instructions,
Counter Notices, and Claim  Notices  on behalf of the Shareholders, (ii) to
agree to, dispute or  settle and compromise  any  Claim, Counter Notice and
Claim Notice given hereunder for and on behalf of the  Shareholders,  (iii)
to  receive  and  respond to any notice or other communication given to the
Shareholders hereunder  and  (iv)  to receive all payments on behalf of the
Shareholders pursuant to this Escrow  Agreement.  The Escrow Agent, NRC and
SELECT  shall  be  fully  protected  in  dealing   exclusively   with   the
Representative  as  the  authorized  agent  of  the  Shareholders  and  the
Shareholders  shall  indemnify  and hold harmless the Escrow Agent, NRC and
SELECT  from  any liability arising  out  of  or  in  connection  with  the
authorization herein granted the Representative to act for and on behalf of
the Shareholders.

     SECTION 4.  For tax purposes, interest earned on the Escrow Fund shall
be taxed to the Shareholders  in  proportion  to  their share of the Merger
Consideration as shown on EXHIBIT "C" of the Merger  Agreement, except only
so much of same that is actually distributed to NRC during  any tax period.
The  Shareholders  shall  furnish  the  Escrow  Agent  with  their taxpayer
identification   numbers  simultaneously  upon  execution  of  this  Escrow
Agreement and a statement  from  the Shareholders that they are not subject
to  backup  withholding.   The  Escrow   Agent   shall   disburse   to  the
Representative for distribution to the Shareholders, in accordance with the
Merger  Consideration  Allocation  in  EXHIBIT "C" of the Merger Agreement,
thirty percent (30%) of the net income earned  during  each  calendar  year
within thirty (30) days after the end of such year.

     SECTION  5. With respect to the Escrow Stock, the following provisions
shall apply:

               (a)  Each stock certificate evidencing Escrow Stock shall be
in the name of  "SouthTrust  Bank,  N.A.,  as  Escrow  Agent  under  Escrow
Agreement dated August 29, 1997."

               (b)  Whenever  a  disbursement is made from the Escrow Fund,
such disbursement shall be prorata  between  the  money  and the NRC Common
Stock  deposited in escrow with respect to each Shareholder  in  accordance
with EXHIBIT  "C"  of the Merger Agreement.  For this purpose, the value of
the Escrow Stock shall be determined in accordance with Section 5(c) below.

               (c)  The  value  of  the  NRC  Common  Stock for purposes of
paying  any  portion  of  the Escrow Funds to NRC or SELECT  shall  be  the
closing sale price of such stock on the NASDAQ National Market (as reported
by the WALL STREET JOURNAL) on the fifth  trading day preceding the date of
distribution.

               (d)  Whenever  a  distribution  of Escrow Stock is made from
the  Escrow  Fund,  the  Escrow  Agent  shall effect such  distribution  by
delivering  the  Escrow  Stock  to  the  transfer  agent  with  appropriate
instructions to reissue the stock certificate(s)  to  the  persons entitled
thereto.

               (e)  While  the  NRC  Common  Stock is held in escrow,  each
Shareholder  depositing such stock with the Escrow  Agent shall be entitled
to instruct the Escrow Agent regarding the voting of  his  shares and shall
be entitled to all dividends declared thereon, except that NRC stock issued
pursuant  to  a stock dividend, stock split, or other transaction  affected
without consideration shall continue to be held in the Escrow Fund.

     SECTION 6.  All  notices  and  other  communications under this Escrow
Agreement shall (a) be in writing (which shall  include  communications  by
facsimile),  (b)  be (i) sent by registered mail or certified mail, postage
prepaid, return receipt  requested  or  by  facsimile, or (ii) delivered by
hand,  (c)  be given at the following respective  addresses  and  facsimile

or at such other address or facsimile number or  to  the  attention of such
other person as the party to whom such information pertains  may  hereafter
specify  for  the  purpose  in a notice to the other specifically captioned
"Notice of Change of Address,"  and (d) be effective or deemed delivered or
furnished (i) if given by mail, on  the  third day after such communication
is deposited in the mail, addressed as above  provided,  (ii)  if  given by
facsimile, when such communication is transmitted to the appropriate number
determined  as  above  provided  in  this  Section  6  and  the appropriate
acknowledgement is received and (iii) if given by hand delivery,  when left
at  the  address of the addressee addressed as above provided, except  that
notices of  a  change  of  address  or facsimile number shall not be deemed
furnished until received.

     SECTION 7. (a) The Escrow Agent  shall  not  be under any duty to give
the property held hereunder any greater degree of care  than  it  gives its
own similar property.

               (b)  The   Escrow   Agent  may  act  in  reliance  upon  any
instrument or signature believed to  be  genuine  and  may  assume that any
person  purporting  to  give any writing, Initial Notice,  Counter  Notice,
Claim  Notice,  Claim,  advice   or  instruction  in  connection  with  the
provisions hereof has been duly authorized to do so.

               (c)  The Escrow Agent may act relative hereto upon advice of
counsel in reference to any matter  connected  herewith  and  shall  not be
liable for any acts or omissions unless caused by its negligence or willful
misconduct.

               (d)  This Escrow Agreement sets forth exclusively the duties
of  the  Escrow  Agent with respect to any and all matters pertinent hereto
and no implied duties  or  obligations  shall  be  read  into  this  Escrow
Agreement against the Escrow Agent.

               (e)  The  Escrow  Agent  makes  no  representation as to the
validity,  value,  genuineness  or the collectibility of  any  security  or
document, or instrument or property held or delivered to it.

               (f)  NRC and Shareholders  agree  that they shall be equally
responsible for the payment of all reasonable expenses,  disbursements  and
advances incurred or made by the Escrow Agent in performance of such duties
hereunder,  including  reasonable  fees,  expenses and disbursements of its
counsel.  The Shareholders' share of any such  fees  and  expenses  of  the
Escrow  Agent  may  be  withheld  and  paid  from  the  Escrow  Fund.   The
immediately  preceding  sentence  survives, despite any termination of this
Escrow Agreement or the resignation or removal of the Escrow Agent.

               (g)  The Escrow Agent  does  not  have and will not have any
interest  in  any  of the Escrow Fund deposited or held  hereunder  but  is
serving only as escrow holder and having only possession thereof.

               (h)  All  Escrow  Fund received by the Escrow Agent shall be
invested and reinvested by the Escrow  Agent in treasury notes not having a
greater maturity than one year which may  be  purchased  through SouthTrust
Securities, Inc., except the Escrow Agent may hold a sufficient amount in a
money  market  fund  (which may include a money market fund of  the  Escrow
Agent or its affiliate) to meet anticipated distributions.

               (i)  In the event the Escrow Agent before the termination of
the escrow created by  this  Escrow  Agreement receives or becomes aware of
conflicting demands or claims with respect  to this escrow or the rights of
any of the parties hereto, or any funds, securities,  property or documents
deposited herein or affected hereby, the Escrow Agent shall  have the right
to discontinue any or all further acts on its part until such  conflict  is
resolved  to  its  satisfaction.   The  Escrow Agent shall have the further
right  but  not  the  obligation  to  commence  or  defend  any  action  or
proceedings for the determination of such  conflict  including, but without
limiting the generality of the foregoing, a suit in interpleader brought by
the  Escrow  Agent.   In  the  event  the  Escrow  Agent files  a  suit  in
interpleader and delivers to the court all funds, securities,  property  or
documents  then  in deposit hereunder, it shall thereupon be fully released
and discharged from  all  further obligations to perform any and all duties
or  obligations  imposed  upon  it  by  this  Escrow  Agreement.   NRC  and
Shareholders agree that they  shall  be equally responsible for the payment
of  all  costs,  damages,  judgments  and  expenses,  including  reasonable
attorneys' fees, suffered or incurred by the  Escrow  Agent  in  connection
with  or  arising  out of its escrow (except those caused by Escrow Agent's
own negligence or willful  misconduct).    However,  as between NRC and the
Shareholders,  the nonprevailing party with respect to  a  Claim  shall  be
required to pay  the  costs  and expenses of the prevailing party including
the prevailing party's share of  all  of the costs, damages and expenses of
the Escrow Agent, if any.

               (j)  The Escrow Agent shall  not  be liable for any error of
judgment  or  for  any  act  done or omitted by it in good  faith,  or  for
anything which it may in good  faith do or refrain from doing in connection
herewith; nor shall the Escrow Agent  be  liable  if,  in  the event of any
dispute or question as to its duties or obligations hereunder,  it  acts in
accordance  with  written  opinion  of its legal counsel, which may include
attorneys who are members of or who are  employed by the Escrow Agent.  The
Escrow Agent is authorized to act upon any  document  believed  by it to be
genuine and to be signed by the proper party or parties and will  incur  no
liability in so acting.

     SECTION 8. (a) This   Escrow   Agreement   and  the  Merger  Agreement
constitute the entire understanding among the parties  in  connection  with
the subject matter hereof,
and no waiver or modification of the terms hereof shall be valid unless  in
writing  signed  by  the party to be charged and only to the extent therein
set forth.

               (b)  This   Escrow   Agreement  shall  be  governed  by  and
construed in accordance with the internal  substantive  laws  and  not  the
choice of laws rules of the State of Alabama.

               (c)  This  Escrow  Agreement shall be binding upon and inure
to   the   benefit  of  the  parties  hereto,   their   respective   heirs,
administrators, executors, successors and assigns.

               (d)  This  Escrow Agreement may be executed in any number of
counterparts, each of which  shall  be  deemed  an  original of this Escrow
Agreement and all of which taken together shall constitute one and the same
instrument.

               (e)  If one or more provisions of this  Escrow Agreement are
held  to  be  unenforceable under applicable law, such provision  shall  be
excluded  from this  Escrow  Agreement  and  the  balance  of  this  Escrow
Agreement shall be enforceable in accordance with its terms.

     IN WITNESS  WHEREOF,  each  of  the  parties  hereto has executed this
Escrow Agreement the day and year first above written.

                     Report of Independent Auditors

The Board of Directors and Stockholders
TXEN, Inc.

We  have audited the accompanying balance sheets of TXEN, Inc. as of June 30,
1997 and 1996, and the related statements of operations,  changes  in  stock-
holders' equity  and  cash  flows  for  the  years then ended. These financial
statements are the responsibility of the  Company's management.  Our responsi-
bility is to express an opinion on these financial  statements  based  on  our
our audits.

We  conducted  our  audits  in  accordance  with  generally accepted  auditing
standards.  Those  standards  require  that  we  plan and perform the audit to
obtain reasonable  assurance  about  whether the financial statements are free
of  material  misstatement.  An audit  includes  examining,  on  a test basis,
evidence supporting the amounts and disclosures  in the  financial statements.
An  audit also includes  assessing the accounting principles used and signifi-
cant estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present fairly,  in
all  material  respects, the financial position of TXEN, Inc. at June 30, 1997
and  1996,  and  the  results  of its  operations and its cash flows  for  the
years then ended in conformity  with generally  accepted accounting principles.

As discussed in Note 1 to the financial statements, in 1996 the Company changed
its method of accounting for depreciation.

                         Notes to Financial Statements

                             June 30, 1997 and 1996


1. ACCOUNTING POLICIES

Organization
- ------------

TXEN,  Inc. (the  Company) facilitates the administration of health benefits by
providing  healthcare  organizations  hardware  and  software solutions through
either outsourcing or turnkey agreements primarily  in the United States.   The
Company  also provides  data  processing  services  through  management service
organization (MSO) agreements.

Cash and Cash Equivalents
- -------------------------

The Company considers all highly liquid  investments with a maturity  of  three
months or less when purchased to be cash equivalents.

Revenue Recognition
- -------------------

Outsourcing/MSO:  Outsourcing and MSO fees are recognized in the  period  they
are earned.

System Sales:  Software license fees and equipment revenue are recognized upon
delivery   of  the software  product to the  customer,  unless the Company has
significant related obligations remaining.  Revenue  requiring any significant
obligations to customers is deferred and recognized once the remaining obliga-
tions become insignificant.

Professional Services:  Revenue from professional services is recognized either
(i) as the services are performed based on the Company's standard rates for the
applicable services; or, (ii) as contract milestones are achieved, if specified
and  required  under  the contract with the customer. Revenue from postcontract
customer support is recognized in the period the customer support services  are
provided.

Concentration of Credit Risk and Financial Instruments:  Financial  instruments
which subject the Company to credit risk are  primarily trade  accounts receiv-
able.  Concentrations of credit risk with respect to trade accounts  receivable
are limited due to the large number and diversity  of customers comprising  the
Company's customer base.   Management believes that  any  risk  associated with
trade  accounts  receivable  is adequately provided  for  in the  allowance for
doubtful  accounts.   The Company generally does not require collateral on  its
trade accounts receivable.

1. ACCOUNTING POLICIES (CONTINUED)

Software Development Costs
- --------------------------

Under Statement of Financial Accounting Standards No. 86, "Accounting for Soft-
ware Costs", once technological feasibility is established related to software
development costs for new products  or for enhancements  to existing  products
which  extend the product's useful  life,  the costs are capitalized until the
product or enhancement is available for release to customers,  after which the
capitalized costs are amortized over the product's estimated life giving  con-
sideration   to   estimates  of recoverability and net realizable value. Total
costs  capitalized for software development  were $687,338 and $-0- during the
years ended June 30, 1997 and 1996, respectively.

Capitalized software development costs are being  amortized  over five  years.
Accumulated amortization of capitalized software development cost was  $25,887
at  June 30, 1997.  The Company capitalized interest cost  of $27,177  for the
year ended June 30, 1997 related to software development costs.

Inventory
- ---------

Inventory is carried at the lower of cost or market using the specific identi-
fication method.

Property and Equipment and Change in Depreciation Method
- --------------------------------------------------------

Property and equipment is  stated on the basis  of  cost.  Property and equip-
ment are depreciated over the estimated useful lives  of the assets (generally
three to seven years).  Depreciation and amortization had been provided  using
the  straight-line  method  for  items  purchased  prior  to July 1, 1994, and
double-declining balance for items purchased after July  1, 1994.  During  the
year  ended  June  30,  1996  the Company adopted the straight-line  method of
depreciation for all assets.  The  new  method of depreciation was  adopted to
better match the cost of the property and equipment with the revenues  genera-
ted  by  those  assets  and  has  been applied retroactively  to property  and
equipment acquired in prior years. The effect of the change in fiscal 1996 was
to decrease loss before cumulative effect of the change in accounting  princi-
ple by  approximately $28,400.  The adjustment of $81,615 (after reduction for
income taxes  of $32,252)  to  apply retroactively the new method, is included
in net loss for fiscal 1996.

1. ACCOUNTING POLICIES (CONTINUED)

Income Taxes
- ------------

All income tax amounts and  balances  have been  computed  in  accordance  with
Statement of Financial  Accounting  Standards  No.  109, "Accounting for Income
Taxes."  Under Statement No. 109, the liability method is  used  in  accounting
for income taxes.  Under this method, deferred tax assets  and liabilities  are
determined  based  on differences between the financial reporting and tax bases
of assets and  liabilities and are measured using  the enacted  tax  rates  and
laws  that will  be  in  effect  when  the differences are expected to reverse.

Stock Options
- -------------

The Company has elected to follow Accounting Principles Board Opinion  No.  25,
"Accounting  for Stock Issued to Employees"  (APB  25) and related  interpreta-
tions in  accounting for its employee stock options because the alternative fair
value   accounting   provided  for  under  Statement  of  Financial   Accounting
Standards  No.  123,  "Accounting  for  Stock-Based Compensation,"  (SFAS  123)
requires  use  of  option valuation models  that were not developed for use  in
valuing  employee  stock options.  Under APB 25, because the exercise price  of
the  Company's employee stock options equals the market price of the underlying
stock on the date of the grant, no compensation expense is recognized.

Use of Estimates
- ----------------

The  preparation  of  the  financial  statements  in  conformity with generally
accepted accounting  principles  requires  management  to  make  estimates  and
assumptions that  affect  the amounts reported in the financial  statements and
accompanying notes. Actual results could differ from those estimates.

5. STOCKHOLDERS' EQUITY

On December 16, 1994, the Company entered into a Stock Purchase Option  Agree-
ment with a third-party.  Under the terms of the  agreement,  the Company sold
sold one  share of  convertible   preferred   stock   to the  third-party  for
$1,500,000.  The  Company  also  authorized 1,250,000 shares of Class B common
stock  which  was  reserved  for issuance upon the conversion of the preferred
stock.

On July 17, 1996, the Stock Purchase Option  Agreement with the holder of  the
preferred stock was amended to  allow the  holder of the  preferred  stock  to
accelerate  the  date  to exercise the option to purchase all of the issued and
outstanding  Class  A  common stock  of the Company.  The option is exercisable
for a period of thirty days after  release  of  the Company's audited financial
statements for the year ended June  30, 1997. The holder of the preferred stock
converted all  of  the  preferred  stock  to Class B common stock  which  is  a
condition  precedent to the right to exercise the option to purchase all of the
outstanding  shares of  Class A  common  stock  of  the  Company.  The  Company
expects the  option  to  be  exercised  which  will  require all related  party
balances to be settled prior to the purchase.   As a  result,  accrued officers
salaries  and  the related  interest  payable  have  been classified as current
liabilities on the balance sheet.

7. RELATED PARTY TRANSACTIONS

The Company has a note payable to a stockholder of the Company for $8,333 at at
June  30,  1997  and  1996  bearing  interest at  8%. Payment of  the principal
balance and  accrued  interest  will  be  made upon  demand  except  where  the
Company is restricted from doing  so  by  any agreements  with third-parties in
force at that time.

The  Company  has notes and accrued interest receivable  from  stockholders  of
the Company  of  $418,833  and  $448,783  at  June  30, 1997 and 1996, respect-
tively, which bear interest at 8%.

The Company incurred $269,202 in expenses with an affiliated  company for  con-
tracted services of which $38,857 is included in accounts payable  at June  30,
1997.   The  Company  had $188,037 of revenue from an affiliated company during
the year ended June 30, 1997.

8. SAVINGS AND RETIREMENT PLAN

The  Company  has  a savings and  retirement   plan  (Plan)  for  all  eligible
employees pursuant to Section 401(k) of the Internal Revenue Code.  The Company
will  match  employee   contributions  to  the  Plan  at  a   level  determined
annually  by  the Company's Board of Directors.  The Company's contribution for
the years  ended  June  30, 1997 and 1996 was $6,009 and $3,400, respectively.

9. STOCKHOLDERS' AGREEMENT

Certain members of management are also stockholders of the  Company  and  owned
approximately  60%  of the  Class A  common  stock at  June 30,  1997.  Under a
stock purchase  agreement,  the  Company  is committed to purchase management's
common stock in the event  of  death,   retirement  or  termination  of employ-
ment.  The  price to be  paid  for  the  common  stock is set by formula in the
Employee Stock Purchase Agreement. As  discussed  in Note  5, the holder of the
Class B common stock has the right to  exercise an option  to  purchase  all of
the outstanding shares of Class A  common stock  of the Company for a period of
30  days  after  release  of  the  Company's  audited  financial statements for
the year ended June 30, 1997 which  would include all the stock held by members
of management.

10. CONTINGENCY

The  Company entered into an agreement with a customer whereby the Company must
deliver  the final version of software currently under development by August 1,
1999. If  the  software  is  not  ready  to  be  released  to  the  customer by
August 1,  1999,  the  Company  must  pay  a penalty  of   $195,000. Management
estimates that delivery of the software under development will occur  prior  to
the  deadline  and  no  penalty  will  be incurred and, therefore,  no  accrual
for  this contingency has been recorded  in  the financial statements.

11. STOCK OPTION PLANS

During 1996, the Board of Directors approved  the  TXEN, Inc.,  1996  Incentive
Stock Option Plan  which  authorized the issuance of options to purchase  up to
100,000 shares of common  stock  and  the  Key  Employee Incentive Stock Option
Plan which authorized the issuance of options to purchase up  to 40,000  shares
of common stock.  All options under the 1996 Plans have  5-year  terms.  Incen-
tive stock options  vest  and   become  exercisable  at the  end of  2 years of
continued employment while non-qualified  stock  options  are  exercisable upon
grant.  Pro forma information  regarding net income  is  required by SFAS  123,
and has  been determined as if the Company had accounted for its employee stock
options under the fair value method required  by  SFAS 123.  The fair value for
these options was estimated at the date of grant using the minimum value method
with  the  following assumptions for 1996:  risk-free interest rates of  6.30%;
weighted-average expected life of the options of 4 years; no volatility factors
of the expected market price of the Company's common stock because the  Company
is privately held; and no dividend yields.

If the Company had adopted SFAS 123 in accounting for its stock options granted
in fiscal year  1996, its net income would have been decreased by approximately
$31,000.  For  purposes  of  pro  forma  disclosures,  the estimated fair value
of  the  options  is  amortized  to  expense over the options'  vesting  period.
The effect of applying pro-forma  disclosures based on SFAS 123 are  not likely
to be  representative  of  the  effects  on future net income.  As of June  30,
1996, there were no  options  which  had  been  exercised.  During fiscal 1997,
123,371  shares  were  granted  with an exercise price of $6.20 and remain out-
standing  at  June  30,  1997.   The  weighted  average  fair value of options
granted during the year was $6.78 with a weighted average  contractual life of
4.2 years.



                              EMPLOYMENT AGREEMENT


     THIS AGREEMENT is entered into on the 16 day of December, 1994, by and

principal  place  of  business  located  at  4040 Memorial  Parkway  South,

                       W I T N E S S E T H:

     WHEREAS,  TXEN  Company  is engaged in the business  of  managed  care
administration and providing information  systems  and  services to managed
care administrators;

     WHEREAS,  NRC,  as  purchaser, and TXEN, as seller, entered  into  and
consummated a Convertible  Preferred  Stock  Purchase Agreement dated as of
the date hereof (the "Purchase Agreement") whereby  NRC  acquired one share
of  Preferred  Stock of TXEN, and the Employee's continued employment  with
TXEN was a material inducement to NRC to enter into the Purchase Agreement;

     WHEREAS, NRC  has  also entered into a Stock Purchase Option Agreement
of even date herewith giving  NRC the option to purchase all of the capital
stock of TXEN owned by the Employee  together  with the capital stock owned
by the other shareholders of TXEN provided NRC converts the Preferred Stock
into Class B Common Stock; and

     WHEREAS, TXEN and NRC desire to obtain the services of the Employee as
President of TXEN and the Employee is willing to  render  such  services to
TXEN upon the terms and conditions herein set forth;

     NOW,  THEREFORE,  in  consideration  of the mutual promises set  forth
herein and other good and valuable consideration,  the  receipt of which is
hereby acknowledged, the parties agree as follows:

1.   DUTIES AND SALARY.

     (a)  TXEN  agrees  to employ the Employee and the Employee  agrees  to
accept employment by TXEN  on  a  full-time basis as President of TXEN at a
base salary of $8,000 per month payable  during  the Term of Employment, as
hereinafter defined.  Such salary shall be subject  to  increases from time
to  time  as  authorized  by the Board of Directors of TXEN (the  "Board"),
provided any increase in compensation  paid  to  the Employee shall require
the affirmative vote of the director or directors  elected  to the Board by
NRC so long as NRC owns any capital stock of TXEN.

     (b)  The  Employee hereby agrees to undertake such travel  as  may  be
required in the  performance of his duties.  The reasonable travel expenses
of the Employee shall be reimbursed in accordance with TXEN's reimbursement
policy, in effect from time to time.

     (c)  The Employee  shall  carry  out  his  duties  under  the  general
supervision of the Board or its designee.

     (d)  The    Employee's   duties   shall   include   the   duties   and
responsibilities identified  on  Schedule  I attached hereto.  The Employee
shall perform such other tasks and duties as  may be assigned by TXEN, from
time  to  time  and  TXEN reserves the right to change  the  office  and/or
position of the Employee  within  TXEN,  so long as such change is mutually
acceptable.  The Employee shall devote his  full time, attention, skill and
efforts to the tasks and duties assigned by TXEN.   The  Employee shall not
provide services, for compensation, to any other person or  business entity
while employed by TXEN without approval of the Board and NRC.

     (e)  The  Employee  shall  not  be  required  to  relocate beyond  the
Birmingham, Alabama, metropolitan area without his consent.

2.   TERM  OF EMPLOYMENT.  This Agreement shall commence  as  of  the  date
hereof and shall  end  four  years  from  the  date  hereof  (the  "Term of
Employment"),  unless  terminated  earlier  or extended as provided herein.
Upon expiration of the initial Term of Employment unless earlier terminated
as  provided  herein, the Term of Employment shall  continue  automatically
month-to-month  until  terminated by either party with at least thirty (30)
days' prior written notice  with  or  without  cause.   Notwithstanding the
foregoing,  if NRC purchases all of the capital stock of TXEN  pursuant  to
the Stock Purchase  Option  Agreement,  NRC  may  elect  to (1) immediately
terminate the Employee's employment or (2) extend the Employee's employment
for one year after the purchase of all of the capital stock  of TXEN by NRC
in which event the Term of Employment shall be extended by such  additional
period, unless terminated earlier as provided herein.

3.   TERMINATION  BEFORE EXPIRATION OF TERM OF EMPLOYMENT.  The termination
of the employment of  the  Employee during the Term of Employment may occur
in one of the following ways:

     (a)  BY TXEN, FOR CAUSE.   Termination  by  TXEN shall be deemed to be
for cause only upon:

          (i)  Employee's conviction of or pleading guilty to a felony;

          (ii) A good faith determination by the Board  that  the  Employee
               has  breached  either this Agreement, the Purchase Agreement
               or the Stock Purchase Option Agreement;

         (iii) Refusal  or failure  by  the  Employee,  without  reasonable
               excuse or  proper authorization, to carry out any reasonable
               instructions  of the Board consistent with Employee's rights
               or duties as set forth in this Agreement;

          (iv) Material breach  of this Agreement or any material breach of
               any agreement with NRC;

          (v)  The  Employee's  demonstration   of  negligence  or  willful
               misconduct in the execution of his duties, including without
               limitation breach of fiduciary duty  or  the duty of loyalty
               owed TXEN.

     If TXEN intends to terminate for cause, TXEN shall provide  notice  to
Employee  of  intent  to  terminate this Agreement, stating the termination
provision in this Agreement  relied  upon  and  setting forth in reasonable
detail  the  facts  and  circumstances  claimed  to  provide  a  basis  for
termination under the provisions so indicated, and shall  provide  Employee
with  an  opportunity  to  cure the alleged default or breach within thirty
(30) days of receipt of the  notice,  provided  that  if  the matter is not
curable  within  such  thirty  (30) day period, the Employee shall  not  be
deemed in default if the Employee  commences immediately to cure the matter
and proceeds diligently thereafter to  complete  the cure, further provided
that the alleged breach or default must be cured within ninety (90) days of
receipt of the notice.  TXEN shall not be required  to  give  more than one
notice with respect to the same matter.  Notwithstanding the foregoing,  no
notice  and no cure right shall be required with respect to termination for
cause under 3(a)(i) or an act involving theft of information or property of
TXEN.

     (b)  BY  TXEN, WITHOUT CAUSE.  Any termination of Employee by TXEN for
reasons other than  as  set  forth  in  subsections 3(a)(i) through 3(a)(v)
above  shall  be  a  termination without cause.   TXEN  may  terminate  the
employment of Employee  without  cause  by  thirty (30) days' prior written
notice at any time.  If NRC purchases all of  the  capital  stock  of  TXEN
pursuant  to  the  Stock  Purchase  Option Agreement, NRC may cause TXEN to
terminate the employment of Employee  without  cause  immediately after the
closing of such purchase and without giving 30 days' prior notice.

     (c)  BY  THE EMPLOYEE.  The Employee may by written  notice  terminate
his employment at any time during the Term of Employment:

          (i)  For any reason other than for Good Reason (as defined below)
               upon thirty (30) days' prior written notice at any time.

          (ii) For  "Good  Reason,"  defined  as  termination  because of a
               material breach by TXEN of this Agreement including, without
               limitation,  making  a  material  change  in  the Employee's
               duties, responsibilities or authority as set forth  in  this
               Agreement,  without  his  express  written  consent.  In all
               cases  in  which  Employee  intends  to terminate  for  Good
               Reason,  the  Employee  shall provide TXEN  with  notice  of
               intent to terminate this  Agreement,  stating  the facts and
               circumstances  giving  rise  to  a  breach of this Agreement
               claimed  to  provide  a  basis  for  termination  under  the
               provisions  so  indicated, and shall provide  TXEN  with  an
               opportunity to cure  the  alleged  default  or breach within
               thirty (30) days of receipt of the notice, provided  that if
               the  matter  is  not  curable  within  such  thirty (30) day
               period, TXEN shall not be deemed in default if  it commences
               immediately  to  cure  the  matter  and  proceeds diligently
               thereafter to complete the cure, further provided  that  the
               alleged  breach  or default must be cured within ninety (90)
               days  of receipt of  the  notice.   Employee  shall  not  be
               required  to  give more than one such notice with respect to
               the same matter.

     (d)  DEATH OF THE EMPLOYEE.

     (e)  DISABILITY OF EMPLOYEE.   If,  during  the  Term of Employment, a
          physician  selected  by  TXEN  determines that the  Employee  has
          become physically or mentally disabled  so  as  to  be  unable to
          carry out the normal and usual duties of his employment for three
          (3)  continuous  months,  and reasonable accommodation cannot  be
          made to allow the Employee  to  continue  to  perform  his duties
          full-time,  his  employment  hereunder  may be terminated at  the
          election of TXEN or the Employee.

4.   CONSEQUENCES OF TERMINATION.  The termination  of  the  employment  of
Employee will cause the following results:

     (a)  If  the  termination  is by TXEN for cause, or is by the Employee
for any reason other than for Good  Reason,  TXEN  will  pay  the  Employee
within  five (5) days after the date of termination any unpaid salary,  the
amount of any accrued annual vacation pay to which he may be entitled under
TXEN's vacation plan, and benefits.  All such compensation and benefits (if
any) shall be paid only through the date termination occurs.

     (b)  If  the  termination is by TXEN without cause or because of death
or disability, TXEN  shall  pay to the Employee, in addition to the amounts
set forth in 4(a) above, an amount  equal  to  fifty  percent  (50%) of the
Employee's monthly base salary then in effect in monthly installments  over
a three-month period immediately following the termination.

     (c)  If the termination is by the Employee for Good Reason, TXEN shall
pay to the Employee, in addition to the amounts set forth in 4(a) above, an
amount  equal  to fifty percent (50%) of the Employee's monthly base salary
then  in  effect  in   monthly   installments  over  a  three-month  period
immediately following the termination.

     (d)  In the event of the Employee's death or disability, the following
provisions will apply:

          (i)  Upon his death, the  Employee's  estate  will be entitled to
               receive  the  amount  set  forth  in  Section 4(b)  and  the
               benefits set forth in any plans of TXEN  then  in effect and
               applicable  under  the circumstances.  The Employee  or  his
               estate  shall  be  entitled  to  no  other  compensation  or
               benefits in the event of death.

         (ii)  Upon termination on  account of disability, Employee will be
               entitled to receive the amount set forth in Section 4(b) and
               the benefits set forth  in  any plans of TXEN then in effect
               and applicable under the circumstances.  The Employee or his
               personal  representative  shall  be  entitled  to  no  other
               compensation or benefits in the event of disability.

     (e)  The Employee shall not be required  to  mitigate  the  amount  of
payment provided for in this Section 4 by seeking employment.

     (f)  The  amounts  set forth above in this Section 4 shall be paid and
received in complete discharge  of any other obligation of TXEN (or NRC) to
Employee resulting from termination of his employment.

5.   FRINGE BENEFITS.

     The Employee shall participate in any group health insurance, vacation
and sick leave plans, and other benefit plans available to all employees of
TXEN in accordance with their terms  and conditions which may be amended or
terminated by TXEN at any time.

6.   NON-DISCLOSURE COVENANTS AND PROPRIETARY MATTERS.

     (a)  Unless authorized or instructed  in  writing by TXEN and NRC, the
Employee shall not, except as required in the conduct  of  TXEN's business,
during or at any time after the Term of Employment, disclose  to others, or
use,  any of NRC's or TXEN's inventions or discoveries or their  respective
secret  or  confidential  information or data (oral, written, or in machine
readable form) which the Employee  may  obtain  during  the course of or in
connection  with  the  Employee's  employment,  including such  inventions,
discoveries, information, know-how or data relating to machines, equipment,
products,  systems,  software,  contracts, contract  performance,  research
and/or   development,   designs,   compositions,    formulae,    processes,
manufacturing  procedures or business methods, whether or not developed  by
the Employee, by  others  in  NRC  or  TXEN or obtained by NRC or TXEN from
third  parties,  and  irrespective  of  whether  or  not  such  inventions,
discoveries, information, knowledge or data  have been identified by NRC or
TXEN as secret or confidential, unless and until,  and  then  to the extent
and  only  to  the  extent that, such inventions, discoveries, information,
knowledge or data become  available  to  the  public  otherwise than by the
Employee's act or omission.

     (b)  The  Employee  shall not, except as required in  the  conduct  of
TXEN's business, disclose to others, or use, any of the information (which,
if disclosed or used, could  be harmful to NRC or TXEN) relating to present
and prospective customers of NRC  or  TXEN,  business  dealings  with  such
customers,  prospective  sales and advertising programs and agreements with
representatives or prospective  representatives  of NRC or TXEN, present or
prospective sources of supply or any other business  arrangements of NRC or
TXEN, including but not limited to customers, customer lists, costs, prices
and earnings, whether or not such information is developed by the Employee,
by others in NRC or TXEN or obtained by NRC or TXEN from third parties, and
irrespective of whether or not such information has been  identified by NRC
or TXEN as secret or confidential, unless and until, and then to the extent
and  only  to  the extent that, such information becomes available  to  the
public otherwise than by the Employee's act or omission.

     (c)  The Employee  agrees  to  disclose  immediately  to  TXEN  or any
persons  designated  by  it  and  to  assign  to  TXEN or its successors or
assigns, all inventions made, discovered, or first  reduced  to practice by
the Employee, solely or jointly with others, during the Term of  Employment
or  within  a  period  of  six  months from the date of termination of such
employment (either during or outside  of  the  Employee's working hours and
either on or off TXEN's premises), which inventions are made, discovered or
conceived  either in the course of such employment,  or  with  the  use  of
TXEN's time,  material,  facilities or funds, or which are directly related
to any investigations or obligations  undertaken  by TXEN; and the Employee
hereby grants and agrees to grant the right to TXEN  and  its  nominees  to
obtain,  for  its own benefit and in its own name (entirely at its expense)
patents and patent  applications including original, continuation, reissue,
utility  and  design  patents,   and  applications,  patents  of  addition,
confirmation patents, registration  patents, petty patents, utility models,
and  all  other  types  of  patents and the  like,  and  all  renewals  and
extensions of any of them for  those  inventions  in any and all countries;
and  the  Employee  shall assist TXEN, at TXEN's expense,  without  further
charge during the term  of the Employee's employment, and after termination
of the Employee's employment  at  the  same base salary rate (excluding any
bonuses, incentive or deferred compensation  or  other  benefits  and based
upon  a  forty  hour  work  week) as during the last year of the Employee's
employment  (determined on an  hourly  basis  for  this  purpose),  through
counsel designated  by  TXEN, to execute, acknowledge, and deliver all such
further papers, including  assignments, applications for Letters Patent (of
the United States or of any  foreign  country), oaths, disclaimers or other
instruments and to perform such further acts, including giving testimony or
furnishing   evidence   in  the  prosecution   or   defense   of   appeals,
interferences, suits and controversies relating to any aforesaid inventions
as may reasonably be deemed necessary by TXEN or its nominees to effectuate
the vesting or perfecting  in  TXEN or its nominees of all right, title and
interest   in   and   to  said  inventions,   applications   and   patents.
Notwithstanding the foregoing, the Employee need not take any action called
for under this Section 6(c) which will cause undue personal hardship to the
Employee.

     (d)  The Employee  agrees  to  disclose  immediately  to  TXEN  or any
persons  designated  by  it  and  to  assign to TXEN, at its option, or its
successors  or assigns, all works of authorship,  including  all  writings,
computer programs,  software,  and  firmware,  written  or  created  by the
Employee solely or jointly with others, during the course of his employment
by  TXEN  (either  during  or  outside  of the Employee's working hours and
either on or off TXEN's premises), which works are made or conceived either
in the course of such employment, or with the use of TXEN's time, material,
facilities or funds, or which are directly related to any investigations or
obligations undertaken by TXEN; and the Employee  hereby  agrees  that  all
such  works  are  works  made for hire, of which TXEN is the author and the
beneficiary of all rights  and protections afforded by the law of copyright
in any and all countries; and  the  Employee  will  assist  TXEN  at TXEN's
expense  without  further  charges  during the term of his employment,  and
after termination of his employment at the same base salary rate (excluding
any  bonuses,  incentive or deferred compensation  or  other  benefits)  as
during the last  year  of his employment (determined on an hourly basis for
this purpose assuming a  forty  hour work week), through counsel designated
by TXEN, to execute, acknowledge,  and  deliver  all  such  further papers,
including  assignments,  applications  for copyright registration  (in  the
United  States  or in any foreign country),  oaths,  disclaimers  or  other
instruments, and  to  perform such further acts, including giving testimony
or  furnishing  evidence   in   the  prosecution  or  defense  of  appeals,
interferences, suits and controversies  relating to any aforesaid works, as
may  be  deemed  necessary by TXEN or by its  nominees  to  effectuate  the
vesting or perfecting in TXEN or its nominees of all rights and interest in
and to said works  and  copies  thereof,  including the exclusive rights of
copying and distribution.

     (e)  The  Employee  shall  keep  complete,   accurate   and  authentic
accounts,  notes,  data  and records of all inventions made, discovered  or
developed and all works of authorship written or created by the Employee as
aforesaid in the manner and form requested by TXEN.

     (f)  All  computer or  other  hardware,  computer  software,  computer
programs, source  codes,  object codes, magnetic tapes, printouts, samples,
notes, records, reports, documents, customer lists, photographs, catalogues
and other writings, whether  copyrightable  or  not, relating to or dealing
with TXEN's or NRC's business and plans, and those  of  others entrusted to
TXEN  or NRC, which are prepared or created by the Employee  or  which  may
come into  his  possession during or as a result of his employment, are the
property of TXEN  or  NRC,  as  applicable,  and  upon  termination  of his
employment,  the  Employee  agrees  to  return  all such computer software,
computer programs, source codes, object codes, magnetic  tapes,  printouts,
samples,  notes,  records, reports, documents, customer lists, photographs,
catalogues and writings and all copies thereof to TXEN or NRC.

7.   NON-SOLICITATION  AND  NON-COMPETITION.  During the Restriction Period
(as hereinafter defined) within  the United States of America, the Employee
shall not directly or indirectly:

     (a)  Solicit the business of  TXEN  from  any  customer of TXEN or any
entity controlled by TXEN or solicit any employees of  TXEN  to  leave  the
employ of TXEN.

     (b)  Directly or indirectly, hire any employees or former employees of
TXEN  or  any  entity  controlled  by  TXEN  within one year of the date of
termination of his employment with TXEN or cause  any entity with which the
Employee is affiliated to hire any such employees or  former  employees  of
TXEN.

     (c)  Engage  in,  represent  in  any  way  or  be  connected  with, as
consultant,  officer,  director,  partner,  employee, sales representative,
proprietor, stockholder or otherwise (except  for  the  ownership of a less
than 1% stock interest in a publicly-traded corporation where  Employee  is
not  in  a management or control position), any business competing with the
business of  TXEN  as  conducted  by  TXEN on the date hereof or during the
period of Employee's employment by TXEN.

     (d)  As used herein, the Restriction  Period  shall  mean  the  period
while the Employee is employed by TXEN and the following periods:

          (i)  36  months after the date the Employee ceases to be employed
     by TXEN and/or

          (ii)  60 months  after  NRC purchases all of the capital stock of
     TXEN pursuant to the Stock Purchase Option Agreement.

     The  above periods in sections  7(d)(i)  and  7(d)(ii)  shall  not  be
mutually exclusive.   For  example,  if  NRC purchases the capital stock of
TXEN more than 36 months after the Employee  ceases to be employed by TXEN,
the Restriction Period of 7(d)(ii) shall apply  even though the Restriction
Period of 7(d)(i) also applied.  Similarly, if the  Employee  ceases  to be
employed  by TXEN more than 60 months after NRC purchases the capital stock
of TXEN, the  Restriction Period of section 7(d)(i) shall apply even though
the Restriction Period of 7(d)(ii) also applied.

8.   NO CONFLICT.   Employee represents and warrants that he is not a party
to or otherwise subject to or bound by the terms of any contract, agreement
or understanding which  in  any  manner would limit or otherwise affect his
ability to perform his obligations  hereunder, including without limitation
any contract, agreement or understanding  containing  terms  and provisions
similar  in  any  manner  to  those  contained  in Sections 6 and 7 hereof.
Employee  covenants  to  indemnify  and hold NRC, TXEN  and  any  of  their
affiliates harmless from any cost or damages (including attorneys' fees and
expenses) resulting from any breach of the provisions of this Agreement.

9.   SURVIVAL OF COVENANTS, EFFECT.

     (a)  The covenants on the part of  the  Employee contained or referred
to in Sections 6 and 7 above shall survive termination  of  this Agreement,
and  the existence of any claim or cause of action of the Employee  against
TXEN or  NRC,  whether  predicated  on  this  Agreement  or otherwise.  The
Employee  agrees  that  a  remedy  at  law for any breach of the  foregoing
covenants contained or referred to in Sections 6 and 7 would be inadequate,
that TXEN and NRC would suffer irreparable  harm  as  a result and that NRC
and/or TXEN shall be entitled to a temporary and permanent injunction or an
order for specific performance of such covenants without  the  necessity of
proving actual damage to NRC or TXEN and without the posting of any bond or
other  security.   Any  breach  of this Agreement by TXEN or NRC shall  not
release the Employee from his obligations under Sections 6 and 7 hereof.

     (b)  The Employee hereby represents and acknowledges that NRC and TXEN
are relying on the covenants in Sections  6  and  7  in  entering into this
Agreement and the Purchase Agreement and other agreements  related  thereto
and that the restrictions in Sections 6 and 7 are fair and reasonable.  The
Employee  acknowledges that TXEN does business throughout the United States
and that the  geographic  scope  of the covenants in Section 7 is therefore
reasonable and necessary to protect the interests of TXEN.

     (c)  It is the intent of the parties that the provisions of Sections 6
and 7 shall be enforced to the fullest  extent  permissible  under the laws
and  public policies of each jurisdiction in which enforcement  is  sought.
If any  particular provision of Sections 6 and 7 shall be adjudicated to be
invalid or  unenforceable,  such  provision(s) of Sections 6 and 7 shall be
deemed amended to provide restrictions  to  the  fullest extent permissible
and consistent with applicable law and policies, and  such  amendment shall
apply  only  with  respect  to  the  particular jurisdiction in which  such
adjudication is made.  If such deemed  amendment  is  not  allowed  by  the
adjudicating  body, the offending provision, only, shall be deleted and the
remainder of Sections 6 and 7 shall not be effected.

10.  ASSIGNMENT.

     The rights  and  obligations  of  TXEN  under  this  Agreement  may be
assigned  by  TXEN  to  NRC  or to any other successors in interest of TXEN
and/or NRC of that part of the  business  of  TXEN  or  NRC  to  which this
Agreement  applies  or to their respective affiliates.  This Agreement  may
not be assigned and any  duties of the Employee may not be delegated by the
Employee, but any amounts  owing to the Employee upon his death shall inure
to the benefit of his estate.

11.  NOTICES.

     All notices or other communications which may be or are required to be
given, served or sent by either  party  to the other party pursuant to this
Agreement shall be in writing, addressed  to  its/his residence or place of
business as set forth above, and shall be mailed  by  first-class certified
mail, return receipt requested, postage prepaid, next-day  air delivery, or
transmitted  by  facsimiles  or  hand  delivery.   Such  notice  or   other
communication  shall be deemed sufficiently given, served, sent or received
for all purposes  at  such  time  as it is delivered to the addressee or at
such time as delivery is refused by  the addressee upon presentation.  Each
party may designate by notice in writing  an address to which any notice or
communication may thereafter be so given, served  or  sent.   Any notice or
other  communication  sent by Employee to TXEN shall also be sent,  at  the
same time, to NRC.  Notices hand delivered to TXEN or NRC must be delivered
to an officer of TXEN and  NRC  and  all other notices shall be sent to the
attention of the Board, in the case of  TXEN,  or  to the President, in the
case of NRC.

12.  APPLICABLE LAW JURISDICTION.

     This  Agreement  has  been negotiated and executed  in  the  State  of
Alabama, and it shall be governed  by, construed and enforced in accordance
with the internal substantive laws and  not  the choice of law rules of the
State of Alabama.

13.  EFFECTIVENESS/INTERPRETATION.

     The  parties  acknowledge  and  agree  that this  Agreement  has  been
negotiated  at  arm's  length  between  parties equally  sophisticated  and
knowledgeable  in  the  matters dealt with herein.   Each  party  has  been
represented by counsel of  its  or his own choosing.  Accordingly, any rule
of  law  or  legal  decision  that  would  require  interpretation  of  any
ambiguities in the Agreement against  the  party  that  drafted  it  is not
applicable and is waived.

14.  THIRD PARTY BENEFICIARY.

     NRC  is  a  third party beneficiary to this entire Agreement but shall
have no liability  to  pay the compensation due Employee and to perform the
other obligations of TXEN  hereunder.  NRC is not a guarantor of any of the
TXEN obligations hereunder.

15.  SEVERABILITY.

     If any of the articles, sections, paragraphs, clauses or provisions of
this Agreement shall be held  by  a court of last resort to be invalid, the
remainder of this Agreement shall not be affected thereby.

16.  ENTIRE AGREEMENT.

     The  foregoing  contains  the entire  agreement  between  the  parties
relating to the subject matter of this Agreement, and may not be altered or
amended except by an instrument  in  writing  approved  by TXEN and NRC and
signed  by  the  parties  hereto, and this Agreement supersedes  all  prior
understandings and agreements  relating  to  employment  of the Employee by
TXEN.   The  parties acknowledge that any prior oral or written  agreements
between NRC and  the  Employee, if any, are hereby terminated.  The parties
acknowledge that the Employee  and  NRC have also entered into the Purchase
Agreement and Stock Purchase Option Agreement which shall be in addition to
and not in lieu of the provisions of this Agreement.

     IN WITNESS WHEREOF, TXEN and NRC  have  caused  this  Agreement  to be
executed  by  their  duly authorized officers and the Employee has hereunto
set his hand as of the date first above written.
