                               PROSPECTUS SUMMARY

   
         The following summary is qualified in its entirety by the more detailed
information  appearing  elsewhere  in  this  Prospectus  and  in  the  financial
statements and other documents  incorporated by reference into this  Prospectus.
Unless otherwise indicated, all references to annual or quarterly periods  refer
to   the Company's  fiscal  year  ending August 31.  Investors  should carefully
consider the information set forth under the heading "RISK FACTORS".
    

         The Selling  Stockholders  may sell from  time-to-time  an aggregate of
415,689 Shares of the Company's Common Stock at prices  obtainable on the Nasdaq
or as otherwise  negotiated.  Each of the Selling  Stockholders has informed the
Company that he or she does not have any  arrangements  or  agreements  with any
underwriters  or  broker/dealers  to sell the  Shares,  and  intends  to contact
various broker/dealers to identify prospective purchasers. Additionally, agents,
brokers or dealers may acquire Shares or interests therein as a pledgee and may,
from time to time,  effect  distributions  of the  Shares or  interests  in such
capacity. Prior to this offering, the Selling Stockholders beneficially owned an
aggregate  of  415,689  shares,  or less  than  one  percent,  of the  Company=s
outstanding Common Stock, and each individual Selling  Stockholder  beneficially
owned less than one percent of the Company's  outstanding  Common Stock.  If the
Selling   Stockholders   sell  all  the  Shares  offered  hereby,   the  Selling
Stockholders  will not own any shares of the  Company's  Common Stock after this
offering. See "OFFERING BY SELLING STOCKHOLDERS".

         The  offering  by  the  Selling  Stockholders  involves  certain  risks
concerning the nature of the Company's  business,  and other matters.  See "RISK
FACTORS". The Company will not receive any of the proceeds from the sales of the
Shares by the Selling Stockholders.

                                  RISK FACTORS

         Prospective  investors  should  carefully  consider,  together with the
other information herein, the following factors that affect the Company.

Concentration of Revenue
- ------------------------

         Approximately  88%,  76%, and 81% of the  Company's  total  revenues in
fiscal 1997,  fiscal  1996,  and fiscal  1995,  respectively,  were derived from
contracts or subcontracts funded by the U.S.  Government.  These U.S. Government
contracts include military weapons systems  contracts,  funded by the Department
of Defense  ("DOD") that  accounted for  approximately  53%, 57%, and 69% of the
Company's total revenues in such years, respectively.  The Company believes that
the success and  development of this business will continue to be dependent upon
its ability to participate in U.S.  Government  contract programs.  Accordingly,
the Company's  financial  performance may be directly  affected by changing U.S.
Government  procurement  practices  and  policies.   Other  factors  that  could
materially and adversely affect the Company's  government  contracting  business
and  programs  include  budgetary  constraints,  changes in fiscal  policies  or
available  funding,  changes in government  programs or requirements  (including
proposals to abolish certain government agencies or departments,  curtailing the
U.S.  Government's use of technology  service firms, the adoption of new laws or
regulations),  technical  developments  and general economic  conditions.  These
factors  could  cause U.S.  Government  agencies  to  exercise  their  rights to
terminate existing contracts for convenience or not to exercise options to renew
such contracts.

         In addition, certain of the Company's contracts individually contribute
a significant  percentage of the Company's  revenues.  For the year ended August
31,  1997,   the   Company's   two  largest   contracts   (by   revenues)   were
high-performance  systems integration contracts,  which generated  approximately
30% of the  Company's  total  revenues for such period.  These two contracts are
expected to represent less than 15% of fiscal year 1998 revenues.  The Company's
five  largest  contracts  (by  revenues)  generated  approximately  50%  of  the
Company's  total  revenues  for such  period.  The Company  expects  revenues to
continue  to  be  concentrated  in a  relatively  small  number  of  large  U.S.
Government contracts.  Termination of such contracts, or the Company's inability
to renew or replace  such  contracts  when they  expire,  could  materially  and
adversely affect the Company's revenues and income.

Risk of Reductions or Changes in Military Weapons Expenditures
- --------------------------------------------------------------

         Historically,  a majority of the  Company's  revenues (53% for the year
ended August 31, 1997) are related to U.S.  military weapons  systems.  The U.S.
military  weapons budget has been declining in real terms since the  mid-1980's,
resulting in some cases in program  delays,  extensions,  and  cancellations.  A
further significant  decline in U.S. military  expenditures for weapons systems,
or a reduction  in the weapons  systems  portion of the  defense  budget,  could
materially and adversely affect the Company. The loss or significant curtailment
of the Company's U.S.  military  contracts would materially and adversely affect
the Company's revenues and income.



                                        5





         Approximately  20% of the  Company's  revenues in fiscal 1997 were from
contracts related to Ballistic  Missile Defense,  compared to 26% of revenues in
fiscal 1996 and 33% of revenues  in fiscal 1995 from such  contracts.  Strategic
defense  has  existed  for  more  than 26  years  as a  mission  of DOD  through
activities such as the Ballistic Missile Defense ("BMD") program.  If a decision
were made to reduce substantially the scope of current BMD programs,  management
believes that many national and theater missile defense  programs would continue
to be funded by the U.S. Army and Air Force,  and other DOD agencies.  While the
Company has expanded into other markets,  a decision to reduce  significantly or
eliminate  missile defense funding would have an adverse effect on the Company's
revenues and income.

Uncertainty Associated With Government Contracts
- ------------------------------------------------

         The Company performs its services under U.S. Government  contracts that
usually  require  performance  over a  period  of one to five  years.  Long-term
contracts  may be  conditioned  upon  continued  availability  of  Congressional
appropriations.   Variances  between   anticipated   budgets  and  Congressional
appropriations may result in delay, reduction, or termination of such contracts.
Contractors  can  experience  revenue  uncertainties  with  respect to available
contract  funding  during the first  quarter  of the  government's  fiscal  year
beginning   October  1,  until   differences   between   budget   requests   and
appropriations are resolved.

         The  Company's  contracts  with  the  U.S.  Government  and  its  prime
contractors are subject to termination, in whole or in part, either upon default
by the Company or at the  convenience of the  government.  The  termination  for
convenience  provisions generally entitle the Company to recover costs incurred,
settlement expenses, and profit on work completed prior to termination.  Because
the Company contracts to supply goods and services to the U.S. Government, it is
also subject to other risks, including contract suspensions,  audit adjustments,
protests  by  disappointed  bidders of contract  awards  which can result in the
re-opening  of the  bidding  process,  and  changes in  government  policies  or
regulations.

Contract Profit Exposure
- ------------------------

         The Company's  services are provided  primarily  through three types of
contracts:  fixed-price,  time-and-materials and  cost-reimbursement  contracts.
Fixed-price  contracts  require the Company to perform services under a contract
at a stipulated price.  Time-and-materials  contracts  reimburse the Company for
the number of labor hours expended at an established  hourly rate  negotiated in
the  contract,  plus the cost of materials  incurred.  Under cost  reimbursement
contracts, the Company is reimbursed for all actual costs incurred in performing
the contract to the extent that such costs are within the  contract  ceiling and
allowable under the terms of the contract, plus a fee or profit.



                                        6



         The Company  assumes  greater  financial risk on fixed-price  contracts
than  on  either  time-and-materials  or  cost-reimbursement  contracts.  As the
Company  increases  its  commercial  business,  it believes  that an  increasing
percentage  of  its  contracts  will  be  fixed-priced.  Failure  to  anticipate
technical  problems,   estimate  costs  accurately,   or  control  costs  during
performance of a fixed-price contract,  may reduce the Company's profit or cause
a loss.  In  addition,  greater  risks  are  involved  under  time-and-materials
contracts than under  cost-reimbursement  contracts  because the Company assumes
the  responsibility  for the delivery of specified skill at a fixed hourly rate.
Although  management  believes that adequate  provision for its  fixed-price and
time-and-materials contracts is reflected in the Company's financial statements,
no  assurance  can be given that this  provision  is  adequate or that losses on
fixed-price and time-and-materials contracts will not occur in the future.

         To compete  successfully for business,  the Company must satisfy client
requirements at competitive rates.  Although the Company continually attempts to
lower its costs,  there are other information  technology and technical services
companies  that may provide the same or similar  services at comparable or lower
rates than the Company.  Additionally,  certain of the Company's clients require
that their vendors  reduce rates after  services have  commenced.  The Company's
success  will also  depend  upon its  ability to  attract,  retain,  train,  and
motivate  highly  skilled  employees,  particularly  in the areas of information
technology, where such employees are in great demand.

Acquisition Strategy
- --------------------

         Expansion  through  acquisitions  is  an  important  component  of  the
Company's overall business strategy.  The Company has successfully completed ten
strategic acquisitions and alliances since September 1, 1994, most of which have
centered on  information  technology  (IT) and healthcare  information  services
markets.  Since  the  respective  dates of the  acquisitions,  the  Company  has
integrated  these  acquired  entities in order to draw on the Company's  base of
technical  expertise and  capabilities  in designing  solutions for  government,
commercial,  and healthcare clients.  The Company's continued ability to grow by
acquisitions  is  dependent  upon,  and may be limited by, the  availability  of
compatible acquisition candidates at reasonable prices, the Company's ability to
fund or finance  acquisitions on acceptable  terms, and the Company's ability to
maintain or enhance the profitability of any acquired business.

Competition
- -----------

         The  information  services  industry in which the  Company  operates is
highly  fragmented  with no single  company  or small  group of  companies  in a
dominant position.  The Company's  competitors include large,  diversified firms
with substantially  greater financial resources and larger technical staffs than
those of the Company.  Some of the large  competitors offer services in a number
of markets  which  overlap  many of the same areas in which the  Company  offers
services,  while  certain  companies  are  focused on only one or a few of these
markets. The firms which compete with the Company are consulting firms, computer
services firms, applications software companies and accounting firms, as well as
the computer  service arms of computer  manufacturing  companies and defense and
aerospace firms.


                                        7


         As part of the Company's  business  strategy to enter new markets,  the
Company  intends  to pursue  large  systems  integration  contracts  in both the
government and commercial  markets,  although  competition for such contracts is
intense and many of the Company's  competitors  have greater  resources than the
Company.  While such contracts are working  capital  intensive,  requiring large
equipment and software purchases to be funded by the Company before payment from
the customer,  the Company  believes such  contracts  offer  attractive  revenue
growth and margin expansion  opportunities  for the Company's range of technical
expertise and capabilities.

Attraction and Retention of Professional Staff
- ----------------------------------------------

         The Company's  success will depend in part upon its ability to attract,
retain, train and motivate highly skilled employees, particularly in the area of
information technology.  There is significant competition for employees with the
information  technology  skills  required  to perform the  services  the Company
offers.  Qualified information technology  professionals are in great demand and
are likely to remain a limited resource for the foreseeable future. There can be
no assurance  that the Company  will be  successful  in  attracting a sufficient
number of highly  skilled  employees in the future or that it will be successful
in retaining,  training and  motivating  the employees it is able to attract and
any inability to do so could impair the Company's ability to perform  adequately
its existing contracts and to bid for or obtain new contracts.

Variability of Quarterly Operating Results
- ------------------------------------------

         The  Company's  revenues  and earnings  may  fluctuate  from quarter to
quarter  based on such  factors as the  number,  size,  and scope of projects in
which the Company is engaged,  the contractual terms and degree of completion of
such  projects,  expenditures  required by the Company in  connection  with such
projects,  any  delays  incurred  in  connection  with such  projects,  employee
utilization  rates,  the  adequacy of  provisions  for losses,  the  accuracy of
estimates  of  resources  required to  complete  ongoing  projects,  and general
economic  conditions.  Under  certain  contracts,  the  Company is  required  to
purchase,  integrate  and  deliver to the  customer  large  amounts of  computer
processing systems and other equipment. Revenues are accrued as costs to deliver
these systems are incurred, and as a result, quarterly revenues will be impacted
by fluctuations  related to equipment  purchases which occur on a periodic basis
depending on contract terms and modifications.

                                   THE COMPANY

         The  Company  is  a  leading  provider  of  technical  and  information
technology (IT) services, including information processing,  systems development
and systems integration.  The Company provides these services to a wide range of
clients, including the DOD, other federal agencies, state and local governments,
healthcare and insurance organizations,  and commercial enterprises. The Company
was founded in 1976 to develop  specialized  optical  sensing  capabilities  for
military  weapons  and  ballistic  defense  programs.  Until  fiscal  year 1991,
virtually all of the Company's  revenues were derived under  contracts  with the
federal  government  relating  to high  technology  weapons  systems,  strategic
missile defense and other related


                                        8


aerospace  technologies.  Areas of particular  strength  have included  tactical
technology,  smart  sensing  systems,  simulations,  data  processing,   systems
engineering and systems integration (including software development, networking,
hardware  acquisition and  installation,  user training and system operation and
maintenance).  Beginning in fiscal year 1991, in response to  increasing  budget
pressure on military  procurements,  the Company  strategically began to develop
applications  for  its  technical  capabilities  outside  its  traditional  core
military  business.  Although the Company's core military business has continued
to grow, the Company has  successfully  entered the markets for other government
information technology solutions, as well as information technology solutions in
the healthcare  industry and other commercial  markets.  The Company's  business
strategy consists of three key elements:  (i) maintain the Company's  leadership
in technology;  (ii) apply the Company's  technology to create solutions for new
clients; and (iii) make strategic  acquisitions and form alliances to expand the
business of the Company and gain industry knowledge.  The Company's business and
financial  performance are subject to risks and  uncertainties,  including those
discussed above. See "RISK FACTORS."

         The Company is organized in four strategic  business units,  reflecting
the  particular  market  focus  of  each  line  of  business.  The  Defense  and
Intelligence unit (formerly  referred to as Nichols Federal) provides  technical
services  primarily  to  U.S.   Government  defense  agencies.   The  Government
Information  Technology unit (formerly  referred to as Nichols InfoFed) provides
information  and technology  solutions and services to a variety of governmental
agencies.  Nichols  InfoTec  provides  information  and  technology  services to
various commercial clients, other than healthcare clients. Nichols TXEN provides
information services to clients in the healthcare and insurance industries.  The
Company is currently  evaluating  whether the services and products  provided to
the  insurance  industry  should  continue to be included  with  Nichols TXEN or
reorganized  into Nichols  InfoTec.  For the nine months ended May 31, 1998, the
percentage  of total  revenues  attributable  to the  four  business  units  was
approximately 55% for Defense and Intelligence,  24% for Government  Information
Technology, 10% for Nichols InfoTec, and 11% for Nichols TXEN.

         The  Company's  executive  offices are  located at 4040 South  Memorial
Parkway,  Huntsville,  Alabama  35802-1326,  and its  telephone  number is (256)
883-1140.

                        OFFERING BY SELLING STOCKHOLDERS

         The Company is  registering  the sale of an aggregate of 415,689 Shares
of Common Stock by the Selling  Stockholders.  The Selling Stockholders may sell
their Common Stock at such prices as they are able to obtain in the market or as
otherwise  negotiated.  The Company  will  receive no proceeds  from the sale of
Common  Stock by the  Selling  Stockholders.  Additionally,  agents,  brokers or
dealers may acquire Shares or interests  therein as a pledgee and may, from time
to time, effect distributions of the Shares or interests in such capacity.

         The Shares offered by the Selling  Stockholders  were acquired from the
Company  in  connection  with the  merger of a  wholly-owned  subsidiary  of the
Company with and into Welkin Associates,  Ltd. (the "Welkin  Acquisition').  The
Welkin  Acquisition was completed pursuant to the terms of an Agreement and Plan
of Merger  dated  June 26,  1998 (the  "Merger  Agreement").  As a result of the
consummation  of the  merger,  all  issued  and  outstanding  shares  of  Welkin
Associates, Ltd. were exchanged for 415,689 shares

                                        9

of the Company's  Common  Stock.  As part of the Merger  Agreement,  the Company
agreed to effect a  registration  of all shares of the  Company's  Common  Stock
received  by the  Selling  Stockholders  in the Welkin  Acquisition  in order to
permit the Selling Stockholders to effect sales of such Shares from time to time
in the market or in privately negotiated transactions.  Accordingly, the Company
has  filed  with the  Commission,  under  the  Securities  Act,  a  Registration
Statement on Form S-3, of which this  Prospectus is a part,  with respect to the
resale of the  Shares  from  time to time on the  Nasdaq  National  Market or in
privately  negotiated  transactions.  The Company  has agreed to use  reasonable
efforts to keep such  Registration  Statement in effect for up to two years from
the  date  of  its  effectiveness   or,  if  earlier,   until  the  distribution
contemplated in this Prospectus is completed.

         Each of Carl W.  Monk,  Jr.,  David  Thomas,  and  Alan A.  Ross  was a
director of Welkin Associates,  Ltd. ("Welkin") at the time that Welkin became a
wholly-owned  subsidiary of the Company on July 28, 1998.  In addition,  Carl W.
Monk was President,  Treasurer,  as well as a stockholder.  Each of Alan A. Ross
and Jose Jimenez was a Vice President and  stockholder,  and Patricia Toomey was
Secretary and a stockholder at that time.

         The  following  table sets forth the name of each Selling  Stockholder,
the number of shares of Common  Stock owned by each Selling  Stockholder  before
the  offering,  the number of shares of Common  Stock to be sold by each Selling
Stockholder,  the number of shares owned by each Selling  Stockholder  after the
offering, and the percentage of shares of Common Stock owned after the offering.
For  purposes  of this  table,  the  Company  has assumed the sale of all Shares
registered hereby, although the Company is not aware of any present intention of
any Selling Shareholder to sell such Shares.

         All  or  a  portion  of  the  Shares  offered  hereby  by  the  Selling
Stockholders  may be delivered  and/or sold from time to time in transactions on
the Nasdaq  National  Market,  in  privately  negotiated  transactions,  or by a

in excess  of  customary  commissions).  There is no  assurance  that any of the
Selling Stockholders will sell any or all of the Shares offered by them.

         Any Selling  Stockholder and any broker-dealer that participates in the
distribution  may under  certain  circumstances  be deemed to be  "underwriters"
within the meaning of the Securities Act, and any  commissions  received by such
broker-dealers and any profits realized on the resale of Shares may be deemed to
be underwriting discounts and commissions under the Securities Act. Each Selling
Stockholder  may  agree  to  indemnify  such   broker-dealers   against  certain
liabilities,  including  liabilities under the Securities Act. In addition,  the
Company  has  agreed  to   indemnify  in  certain   circumstances   the  Selling
Stockholders against certain liabilities including liabilities arising under the
Securities  Act.  The Selling  Stockholders  have agreed to indemnify in certain
circumstances the Company against certain liabilities.

Item 15.  Indemnification Of Directors And Officers.
- ----------------------------------------------------

         Section  145  of  the   Delaware   General   Corporation   Law  permits
indemnification  by the Company of any director,  officer,  employee or agent of
the Company or person who is serving or was serving at the Company's  request as
a  director,  officer,  employee  or  agent  of  another  corporation  or  other
enterprise,  against expenses (including attorneys' fees), judgments,  fines and
amounts  paid  in  settlement,  actually  and  reasonably  incurred  by  him  in
connection  with the  defense of any  threatened,  pending or  completed  action
(whether civil,  criminal,  administrative or investigative),  to which he is or
may be a party by reason of having  been such  director,  officer,  employee  or
agent  provided  that he  acted in good  faith  and in a  manner  he  reasonably
believed to be in or not opposed to the best interests of the Company, and, with
respect to any criminal action or proceeding had no reasonable  cause to believe
his conduct was  unlawful.  The Company also has the power under  Section 145 to
indemnify persons set forth above from threatened,  pending or completed actions
or suits by or in the right of the Company to procure a judgment in its favor by
reason of the fact that such person was a director,  officer,  employee or agent
of the Company or is or was serving at the request of the Company as a director,
officer, employee or agent of another corporation or enterprise against expenses
actually  and  reasonably  incurred  by him in  connection  with the  defense or
settlement of the action if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best  interests of the  Company,  except
that no indemnification can be made with regard to any claim, issue or matter as
to which the person


                                      II-1

has been adjudged to be liable for  negligence or misconduct in the  performance
of his duty to the Company unless and only to the extent that the Delaware Court
of  Chancery or the court in which the action was  brought  determines  that the
person was fairly and  reasonably  entitled to  indemnity.  Any  indemnification
(unless  ordered by a court) must be made by the Company only as  authorized  in
the specific case upon a  determination  that  indemnification  of the person is
proper in the  circumstances  because  he has met the  applicable  standards  of
conduct.  The determination must be made by the Board of Directors by a majority
vote of a quorum  consisting of directors who are not parties to the action,  or
if a quorum is not obtainable or, even if obtainable,  a quorum of disinterested
directors so directs,  by independent  counsel in a written  opinion,  or by the
stockholders.  The Company may pay the expenses of an action in advance of final
disposition  if  authorized by the Board of Directors in a specific  case,  upon
receipt  of an  undertaking  by the person to be  indemnified  to repay any such
advances  unless it shall  ultimately be determined that such person is entitled
to be indemnified by the Company as authorized by law.

         Article Nine of the Company's By-laws provides for  indemnification  of
the Company's directors,  officers,  employees or agents to the extent permitted
by Section 145 of the  Delaware  General  Corporation  Law.  Article Nine of the
Company's  By-laws  further  provides that the Company may purchase and maintain
insurance  on  behalf  of  those  persons   described   above  as  eligible  for
indemnification for liability arising out of such person's duties or status with
the Company whether or not indemnification in respect of such liability would be
permissible.

         The Company has in effect an officers and directors liability insurance
policy with National  Union Fire  Insurance  Company of  Pittsburgh.  The policy
provides  indemnity  to the  directors  and officers of the Company for the loss
arising  from any claim by reason of a wrongful  act where there is no corporate
indemnification. The insurance provides for the Company to be reimbursed for any
indemnification  it may be required by statute or the Company's  By-laws to make
to any of its directors  and officers in connection  with a claim by reason of a
wrongful act. Pursuant to exclusions,  the policy covers negligent acts, errors,
omissions or breach of duty by a director or officer.  The principal  exclusions
from coverage include the following:  (i) claims involving various violations of
Section 16(b) of the Securities  Exchange Act of 1934;  (ii) dishonest acts; and
(iii) libel,  slander,  or  non-monetary  damages.  The policy has no deductible
amount  per   director  or  officer  for  each  loss.   A  $500,000   deductible
self-insurance  retention  applies to the Company.  The limit of liability under
the policy is $5,000,000 in the aggregate  annually in excess of deductibles and
participations.

Item 17.  Undertakings.
- --------  -------------

The undersigned registrant hereby undertakes:

          (1) To file,  during  any  period in which  offers or sales are being
made, a post-effective amendment to this registration statement:

          (i) To include any  prospectus  required  by Section  10(a)(3) of the
              Securities Act.

          (ii)To reflect in the prospectus any facts or events arising after the
              effective date of the registration statement (or the  most  recent
              post-effective  amendment thereof) which,  individually or in the
              aggregate,  represent a fundamental change in the information set
              forth  in  the  registration   statement.   Notwithstanding   the
              foregoing,  any  increase  or  decrease  in volume of  securities
              offered (if the total dollar value of  securities  offered  would
              not exceed that which was  registered) and any deviation from the
              low or high end of the estimated  maximum  offering  range may be
              reflected  in the form of  prospectus  filed with the  Commission
              pursuant  to Rule  424(b) if, in the  aggregate,  the  changes in
              volume  and  price  represent  no more  than a 20%  change in the
              maximum aggregate offering price set forth in the "Calculation of
              Registration Fee" table in the effective registration statement.
      
        (iii) To include any material  information  with respect to the plan of 
              distribution   not  previously   disclosed  in  the  registration 
              statement or any  material  change  to  such  information  in the 
              registration statement.

         Provided,  however,  that  paragraphs  (1)(i) and (1)(ii)  above do not
apply if the information  required to be included in a post-effective  amendment
by those paragraphs is contained in the periodic reports filed by the registrant
pursuant  to  Section  13  or  Section  15(d)  of  the  Exchange  Act  that  are
incorporated by reference in the registration statement.

                                      II-3


          (2)     That, for the purpose of determining  any liability  under the
                  Securities  Act, each such  post-effective  amendment shall be
                  deemed  to be a new  registration  statement  relating  to the
                  securities   offered   therein,   and  the  offering  of  such
                  securities at that time shall be deemed to be the initial bona
                  fide offering thereof.

         (3)      To  remove  from  registration  by means  of a  post-effective
                  amendment any of the securities  being registered which remain
                  unsold at the termination of the offering.

         The  undersigned  Registrant  hereby  undertakes  that, for purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
Registrant's  Annual  Report  pursuant to section  13(a) or section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  Section  15(d)  of  the
Securities  Exchange  Act of 1934) that is  incorporated  by  reference  in this
Registration  Statement  shall  be  deemed  to be a new  Registration  Statement
relating to the securities  offered herein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         The undersigned Registrant hereby undertakes that:

         (1) For purposes of determining  any liability under the Securities Act
of 1933, the  information  omitted from the form of prospectus  filed as part of
this  Registration  Statement in reliance upon Rule 430A and contained in a form
of  prospectus  filed by the  Registrant  pursuant to Rule  424(b)(1)  or (4) or
497(h) under the Securities Act shall be deemed to be part of this  Registration
Statement as of the time it was declared effective.

         (2) For the purpose of determining  any liability  under the Securities
Act of 1933,  each  post-effective  amendment that contains a form of prospectus
shall be deemed to be a new  Registration  Statement  relating to the securities
offered  therein,  and the  offering  of such  securities  at that time shall be
deemed to be the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the  Registrant  pursuant  to  the  foregoing  provisions,   or  otherwise,  the
Registrant  has been advised that in the opinion of the  Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against such  liabilities  (other than the payment by the Registrant of expenses
incurred or paid by a director,  officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.



                                      II-4



                                   SIGNATURES

         Pursuant  to the  requirements  of the  Securities  Act  of  1933,  the
Registrant certifies that it has reasonable grounds to believe that it meets all
of the  requirements  for filing on Form S-3 and has duly caused this  Amendment
No.  1 to  the  Registration  Statement  to be  signed  on  its  behalf  by  the
undersigned,  thereunto duly  authorized,  in the City of  Huntsville,  State of
Alabama, on this 16th day of October, 1998.
