                              SUBJECT TO COMPLETION
                   PRELIMINARY PROSPECTUS DATED JUNE 26, 1997
    
                               TRANSITION ANALYSIS
                           COMPONENT TECHNOLOGY, INC.

            498,447 Shares of Common Stock (Par Value $.01 Per Share)

   
     This  prospectus  is being  furnished in connection  with the  contemplated
distribution  (the  "Distribution")  by  Zing  Technologies,  Inc.,  a New  York
corporation  ("Zing") to holders of record of its Common  Stock,  par value $.01
per share  ("Zing  Stock") as of the close of  business  on June 17,  1997,  the
record date to be set by the Board of Directors  of Zing (the "Record  Date") of
all of the  outstanding  shares  of  Common  Stock,  par  value  $.01 per  share
("Company  Stock") owned by Zing in Transition  Analysis  Component  Technology,
Inc., a Delaware  corporation and 90% owned subsidiary of Zing (the "Company" or
"TACTech").  TACTech  will  operate  all  businesses  owned  by it  prior to the
Distribution.
    

      On [date], Zing delivered a stock certificate  representing 498,447 shares
of  Company  Stock to The Bank of New York  (the  "Transfer  Agent"),  as Escrow
Agent, to be held until the Distribution is effected (the "Distribution  Date").
The  Distribution  will be made beginning on or about the  Distribution  Date to
holders of record of Zing Stock as of the Record  Date on the basis of one share
of Company Stock for each five shares of Zing Stock held.  No fractional  shares
will be issued.  Fractional  shares will be  acquired  by TACTech for cash.  The
Distribution will take place after the Company's certificate of incorporation is
amended to,  among other  things,  increase the number of shares of common stock
authorized to be issued, and after giving effect to a 36.436-for-one stock split
of Company Stock (the "Stock  Split") and will  commence as soon as  practicable
following the Securities and Exchange Commission's  declaration of effectiveness
of the  registration  statement on Form SB-1 of which this  prospectus is a part
under  the  Securities  Act of  1933,  as  amended  (the  "33  Act  Registration
Statement")  and a registration  statement  registering  the Company Stock to be
distributed  under the Securities  Exchange Act of 1934, as amended (the "34 Act
Registration  Statement",  and together with the 33 Act Registration  Statement,
the "Company Registration Statements").  No consideration will be required to be
paid by Zing  stockholders for the shares of Company Stock to be received in the
Distribution.  Neither  Zing  nor the  Company  will  receive  any  proceeds  in
connection  with  the  Distribution.  All  expenses  of  the  Distribution  will
initially be paid by Zing.  The Company,  however,  has agreed to reimburse Zing
for that  portion  of such  expenses  pertaining  directly  to the  costs of the
preparation and filing of the Company's Registration Statements, up to a maximum
amount of $100,000.

   
      There has been no previous public trading market for Company Stock.  While
it is  anticipated  that  Company  Stock will be traded in the  over-the-counter
market  established  for  securities  that  do  not  meet  the  Nasdaq  SmallCap
Market(sm)  listing  requirements  (the "Pink  Sheets")  under the symbol "TRZA"
following the Distribution,  there can be no assurance that any such market will
develop.
    
     Zing  stockholders  who  will  receive  shares  of  Company  Stock  in  the
Distribution,   as  well  as  persons  who  purchase  Company  Stock  after  the
Distribution,  should carefully consider the matters set forth under the caption
"Risk Factors" beginning on page 8 of this prospectus.

                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain  statements  in the  Prospectus  Summary  and under the  captions  "Risk
Factors",  "Business of TACTech",  "TACTech Management's Discussion and Analysis
of  Financial  Condition  and  Results of  Operations",  and  elsewhere  in this
prospectus   constitute   "forward-looking   statements."  Such  forward-looking
statements  involve known and unknown  risks,  uncertainties,  and other factors
which may cause the actual results, performances, or achievements of the Company
(including,    without    limitation,    the    expansion   of   the   Company's
industrial/commercial library (the "Commercial Library") so that the Company can
both better service its existing military and aerospace customers and expand its
customer base from its military and aerospace customers to industrial/commercial
customers;  penetrate  international markets in Europe and the Far East; provide
access to the  Company's  services  through a graphical  user  interface via the
Internet  and the World Wide Web;  and enter  into  strategic  alliances  and/or
co-license   arrangements  to  further   augment  the  Commercial   Library  for
commercial/industrial  applications) to be materially  different from any future
results,   performance,   or   achievements   expressed   or   implied  by  such
forward-looking  statements.  Such factors include, among others, the following:
the downsizing of the U.S.  defense budget,  the  consolidation  of military and
aerospace  manufacturers  and the  corresponding  shrinkage in the production of
semiconductor electronic components for military and aerospace applications; the
resulting weakening of military and aerospace manufacturers who are customers of
the  Company,  which  weakening  could have a heightened  adverse  effect on the
Company   if   the   Company   is   unable   successfully   to   penetrate   the
commercial/industrial  market;  the further  consolidation  of the  military and
aerospace  market  which  consolidation  could  result in a shrinking  number of
customers and potential  customers  for the  Company's  services;  the Company's
success  in  building  the  Commercial   Library;   the  Company's   ability  to
sufficiently  update its  technology;  the Company's  building and training of a
marketing  department to better  penetrate  untapped  markets,  and compete with
existing companies or new entries into the Company's business; the modernization
of the  Company's  services so that the  services  are  accessible  by customers
through a graphic  user  interface on the  Internet;  the  Company's  ability to
maintain and attract key  personnel;  the  Company's  ability to update its data
bases as soon as information is available from its vendors and then to make such
updated  information  available to the Company's  customers on a near real-time,
on-line basis; and other factors  referenced in this prospectus.  The success of
the Company is dependent on the Company's ability  sufficiently to address these
factors and other factors. See "Risk Factors."

   
Until September 29, 1997, all dealers  effecting  transactions in the registered
securities,  whether or not participating in this distribution,  may be required
to deliver a prospectus.

                               PROSPECTUS SUMMARY

     The following is a summary of certain  information  contained  elsewhere in
this  prospectus  and is qualified by the more  detailed  information  set forth
elsewhere in this  prospectus  which should be read in its entirety.  Unless the
context otherwise indicates,  all references to the operations of the Company in
this prospectus shall include the operations of the Company by Zing prior to the
Distribution  and assumes  that the  actions set forth under "The  Distribution"
have taken place. Capitalized terms used in this Summary but not defined in this
Summary  have  the  respective  meanings  ascribed  to  them  elsewhere  in this
prospectus.

                 TRANSITION ANALYSIS COMPONENT TECHNOLOGY, INC.

     TACTech is a 90% owned subsidiary of Zing, incorporated by Zing on February
24, 1987. The mailing address of the Company's  principal  executive  offices is
currently  22700 Savi Ranch Parkway,  Yorba Linda,  California,  92657,  and the
phone number is (714) 974-7676.

     TACTech is a  semiconductor  information  service  company  which  licenses
proprietary  computer  software  tools  combined with  electronic  semiconductor
availability  libraries and data bases that are utilized by various  segments of
the Department of Defense, the defense/aerospace  industry, and industrial users
of high reliability  semiconductors  and  manufacturers and distributors of high
reliability and military grade semiconductors.  A high reliability semiconductor
is a semiconductor  which functions  reliably over a broad temperature range and
has been screened by its  manufacturer  for potential  malfunction  in the early
stages of its use; and a military grade  semiconductor is a semiconductor  which
has been  screened  for  compliance  with U.S.  Department  of Defense  military
specifications. When accessed by customers, the libraries and data bases provide
subscribers  with valuable  tools for  determining  semiconductors  availability
showing the manufacturers  actively producing the subject  semiconductor and the
projected  production  life cycle  (obsolescence)  of such  semiconductors.  The
system identifies  functionally  interchangeable  devices, when available,  from
various  manufacturers.  At present,  the Company's libraries and data bases are
utilized  by  its  customers   primarily  in  connection   with  the  designing,
engineering,  manufacturing  and  maintaining  of  electronic  systems  for high
reliability applications.

     The Company's  continuing goal is to provide  subscribers with "real-time",
on-line  access to the  Company's  data bases.  By so  accessing  the  Company's
library and data bases,  customers can investigate  the source support,  product
identification,   projected  obsolescence  and  interchangeability  of  numerous
electronic components. The Company's library and data bases cross reference each
electronic  component by  projected  production  life cycle and by  functionally
equivalent  components.  Thus, a TACTech  customer can  ascertain  the projected
obsolescence of a given electronic  component and, given the shrinking supply of
semiconductor  component products having military and/or aerospace applications,
locate or design suitable  replacement  components for components as they become
obsolete.

     The Company's relationship with its information providers and the Company's
technology allow the Company  frequently to update its libraries and data bases.
On a daily basis, the Company updates its component library to reflect component
status  changes on an  individual  component-by-component  basis.  Such  updated
libraries  and data  bases are then made  available  to TACTech  customers  on a
real-time,  on-line  basis (i.e.,  the  Company's  library is updated daily when
information  is obtained from or provided by component  manufacturers,  and then
such new information is immediately made available to the Company's  customers),
thus  ensuring  a  nearly  free  flow  of  information  from  semiconductor  and
electronic component manufacturers to TACTech customers.

     Management of the Company  believes that the Company is the only commercial
provider of data services  offering  access to regularly  updated  libraries and
data bases which enable customers,  on a real-time,  on-line basis, to determine
projected  production  life  cycles and  identify  functionally  interchangeable
microcircuits and discrete semiconductor devices.

     The  Company's  libraries  and  data  bases  also  provide  customers  with
information  about  components and  configuration  level  production  life cycle
analyses within the context of the assemblies and subassemblies within which the
components  reside based on  semiconductor  content in particular  designs.  The
Company's built-in software made available to TACTech customers 


                                        4

<PAGE>

allows customers to analyze component usage at the assembly or subassembly level
in a specific design to determine the long term production support and projected
component  availability support of the subject assembly,  subassembly or system.
Through the  Company's  services,  customers are able to  automatically  monitor
their bill of materials based on the semiconductor content of a specific design.
Thus,  when a  discontinued  notification  is processed  with respect to a given
semiconductor  electronic  component included in the customer's design,  TACTech
notifies the customer with an automated  alert signal  linking the  notification
process to the customer's  bill of material.  Thus, the Company's  customers are
notified when components upon which they rely become discontinued. The customers
then  have  ability  to  utilize  the  tools  provided  by  TACTech  to seek out
interchangeable  components  to the extent that the obsolete  component has been
discontinued by the original manufacturer.  Thus, customers are better poised to
modify assemblies, subassemblies and systems.

     Historically,  the Company has focused  its  business on the  military  and
aerospace  markets.  However,  with the  consolidation of aerospace and military
manufacturers and increased  application of industries formerly aligned with the
military/aerospace  industries to commercial  markets;  the Company's goal is to
build  the  Commercial  Library  in order to better  service  its  military  and
aerospace customers and to enter the commercial and industrial markets.

   

     There is not currently a trading market for the Company Stock.  Immediately
following the Distribution.  TACTech  anticipates that the Company Stock will be
listed in the "Pink  Sheets"  under the symbol " TRZA." See "Risk Factors - Lack
of Current Market for TACTech Stock."

     Management  of TACTech does not presently  intend to pay cash  dividends on
the Company  Stock  following  the  Distribution.  The  dividend  policy will be
reviewed  from time to time by TACTech's  Board of Directors  based on TACTech's
earnings, financial position and such other business considerations as its Board
of Directors considers pertinent.

                                The Distribution

     The Board of Directors of Zing will  declare a  distribution  to holders of
Zing Stock,  as of the close of business on the Record Date, on the basis of one
share of Company  Stock (after  giving  effect to the Stock Split) for each five
shares of Zing Stock held on the Record Date. The shares to be distributed  will
constitute 90% of the issued and outstanding shares of Company Stock immediately
following the  Distribution  with the remaining ten percent (10%) being owned by
the  Company's  executive  vice  president,   Malcolm  A.  Baca.  Following  the
Distribution,  the Company  will  operate on a stand alone basis and the Company
Stock will be publicly quoted in the "Pink Sheets".  See "The  Distribution" and
"Description of Capital  Stock." The  Distribution is expected to be tax-free to
Zing  stockholders for Federal income tax purposes.  See "Risk Factors - Certain
Tax Considerations."

         At the Distribution Date, there will be 553,830 shares of Company Stock
of which 498,447 shares of Company Stock will be distributed in the Distribution
to Zing stockholders, based on 2,492,233 shares of Zing Stock outstanding on the
Record Date. See  "Description of Capital Stock." Such  distributed  shares will
constitute 90% of the issued and outstanding shares of Company Stock immediately
following the Distribution.  The Distribution will be one share of Company Stock
for each five shares of Zing Stock held on the Record Date. No fractional shares
will be issued. Fractional shares will be acquired by TACTech for cash. See "The
Distribution -- Manner of Effecting the Distribution."

     As of the  Distribution  Date, the Company and Zing will enter into several
agreements and take certain other actions to define their ongoing relationships.



     Immediately prior to the  Distribution,  Zing will convert all of the loans
due it from TACTech (which intercompany loans approximated $514,000 at March 31,
1997) into  additional  paid-in  capital  of TACTech  without  the  issuance  of
additional  Company  Stock;  Zing has informed the Company that it will guaranty
the  Company's  obligations  under a  credit  facility  provided  by one or more
financial  institutions up to an aggregate  principal amount of $1,500,000.  See
"Certain Transactions --Zing Guaranteed Credit Facility."

     The  Company  and Zing  have  agreed  to  indemnify  each  other  after the
Distribution  with respect to certain  losses,  damages,  claims and liabilities
(including  certain  taxes)  arising  primarily  from  the  operation  of  their
respective businesses. See "Certain Transactions -- Indemnification Agreement."

   
     The Company  will engage  certain  employees  of Zing on a part-time  basis
pursuant to which they will act as  advisors to the Company and will  provide to
the Company  supervisory  financial and strategic  analysis services and various
reporting,  accounting and  administrative  services,  and assist the Company in
developing  its business  plans and strategies for the deployment of its assets.
In connection with providing the management  services,  such Zing employees will
advise in the  development of the Company's  business  plan,  advise the Company
with respect to and  negotiate  material  agreements  on the  Company's  behalf,
coordinate  communications with the Company's  stockholders,  interface with the
Company's counsel,  advise the Company with respect to and negotiate prospective
acquisitions  and  financings,  prepare and file the  Company's  tax returns and
reports  required by applicable  securities  laws and rules of applicable  stock
exchanges,  review and supervise the Company's accounting department and systems
from time to time and suggest  revisions and changes  thereto,  and perform such
further  services  as they may agree to. The  persons  currently  providing  the
services  are Martin S. Fawer,  Don  Guarnieri  and  Michelle  Mastropolo.  Such
services  were  previously  provided by Zing to the Company and were included in
general  corporate  charges.  As of March  31,  1997,  such  charges  aggregated
approximately  $75,000.  By allowing  its  employees  to provide  such  services
directly to the Company after the  Distribution,  rather than through Zing as is
done currently,  Zing will realize a corresponding reduction in payroll expense.
See "Certain Transactions -- Management Services."

     Pursuant to an existing tax  reimbursement  arrangement  applicable  to the
Company  and  Zing,  which  will be of no  further  force and  effect  after the
Distribution,  the Company is  indebted  to Zing in the amount of  approximately
$158,000 as of March 31, 1997 in respect of operation of the Company  during its
fiscal years ended June 30, 1995 and June 30, 1996, and the first nine months of
the current fiscal year.  Such amounts are estimated  based on the operations of
the Company on a stand-alone  basis, and may be adjusted upwards or downwards as
a result of any tax liabilities assessed or removed in the event of a tax audit.
See "Risk Factors -- Possible Lack of Liquidity." Additionally, pursuant to such
tax allocation arrangement and the indemnification agreement, the Company, under
certain  circumstances,  may be required to make further payments to Zing, or be
entitled to  reimbursements  from Zing, in respect of taxes for periods prior to
the  Distribution  Date arising from the operation of its business  prior to the
Distribution Date. See "Certain Transactions."
    

                         Federal Income Tax Consequences
   
     At the  Distribution  Date, Zing expects to receive an opinion from Ernst &
Young LLP to the effect that on the basis of certain  facts and  representations
made by the  managements of Zing and the Company  (including the facts contained
in this  prospectus),  it is more  likely  than not that the  Distribution  will
qualify as a non-taxable  distribution under Section 355 of the Internal Revenue
Code of 1986, as presently amended (the "Code").  For a more detailed discussion
of the potential federal income tax consequences of the Distribution to the Zing
stockholders,  see  "Risk  Factors  --  Certain  Tax  Considerations"  and  "The
Distribution -- Certain Federal Income Tax Consequences of the Distribution."
    

                                   Record Date

   

     The Record Date is June 17, 1997.

    

         Distribution Agent, Escrow Agent, Transfer Agent and Registrar

   

         The Transfer Agent has agreed to hold the stock certificate  evidencing
498,447  shares  of  Company  Stock,  as  escrow  agent,  pursuant  to a certain
agreement  dated as of June 30, 1997.  The Company Stock is to be distributed to
Zing  stockholders  by the escrow  agent upon  receipt of a legal  opinion  from
TACTech's  counsel that the Company  Registration  Statements have been declared
effective   by   the    Securities   and   Exchange    Commission.    See   "The
Distribution-Manner of Effecting Distribution."

                                Distribution Date

     It is expected that the  Distribution  Date will be as soon as  practicable
following the Securities and Exchange Commission's  declaration of effectiveness
of the  Registration  Statement of which this  Prospectus  is a part. As soon as
practicable   thereafter,   the  Transfer   Agent  will  commence   mailing  the
certificates  representing  shares of Company Stock.  Holders of Zing Stock will
not be  required to make any  payment or take any  action,  including  tendering
stock certificates,  in order to receive Company Stock. See "The Distribution --
Manner of Effecting the Distribution."

                                  Risk Factors

     The Zing  stockholders  who will  receive  shares of  Company  Stock in the
Distribution and persons who purchase Company Stock after the Distribution  Date
should  consider  certain  factors  discussed  under the heading "Risk  Factors"
beginning on page 8.

     The  foregoing  is a brief  summary  of certain  terms of the  Distribution
affecting  Zing  and  the  Company  and  their  stockholders.  A  more  complete
description  of the  Distribution  may be found in this  prospectus  under  "The
Distribution".

                                  RISK FACTORS

     Holders of Company  Stock  should be aware  that the  Distribution  and the
purchase and ownership of Company Stock involves certain risks,  including those
described  below,  which could  adversely  affect the value of their holdings of
Company  Stock.  Neither  Zing nor the  Company  makes,  nor has  either of them
authorized any other person to make, any representation  about the future market
value of Company Stock.

Stand Alone Company

     As a  subsidiary  of Zing,  TACTech  has been able to  resort  to  internal
financial resources,  including loans from Zing, to finance operating,  research
and development  requirements.  Although the management of TACTech expects that,
following the  Distribution,  TACTech will have  sufficient  cash generated from
operations,  together with sufficient  availability  under one or more financial
institution  credit  facilities,  which the  Company  will seek to secure on the
strength of Zing's  agreement to guaranty  payments  thereunder,  to finance the
Company's  operating,  research and development  requirements,  the Distribution
will result in Zing's cash  reserves no longer being  available to TACTech other
than pursuant to such a guaranteed  credit  facility.  There can be no assurance
that the Company will be able to secure such a facility on acceptable  terms, or
at all.  Historically,  Zing has provided working capital and long-term loans to
TACTech.  However,  after the  Distribution,  Zing will have no obligation other
than pursuant to such guaranty to extend loans to TACTech or guaranty any of its
indebtedness.  If funds  were  needed  by  TACTech  in  excess  of its  internal
financial  resources  and  such  guaranteed  credit  facility,  there  can be no
assurance that TACTech would be able to obtain  financing or that such financing
would be on terms as favorable as it would have been had TACTech  continued as a
subsidiary  of Zing.  See  "Management's  Discussion  and  Analysis of Financial
Condition and Results of Operations - Liquidity and Capital Resources."

   

     Following the Distribution, charges for securities laws compliance, such as
Securities and Exchange  Commission  filing fees,  legal and accounting fees and
similar types of expenses,  will be borne by TACTech,  or, if initially  paid by
Zing, will be reimbursed by the Company,  which amounts are likely to be greater
than the prior  allocations of corporate  overhead when TACTech was a subsidiary
of Zing,  and will have a  corresponding  depressing  effect on  earnings  going
forward. Additionally, following the Distribution, TACTech will pay compensation
to certain Zing employees  designated to perform management  services,  which is
not  expected to exceed  $100,000 per annum for such  management  services to be
provided which services were previously provided to TACTech by Zing and included
in general  corporate  charges.  By  providing  such  services  directly  to the
Company,  rather than through Zing, Zing will realize a corresponding  reduction
in payroll expenses. See "Certain Transactions Management Services."
     

Absence of Trading Market for Company Stock;
Requirements for Listing Securities on the NASDAQ
SmallCap Market(sm); Application of Penny Stock Rules;
Possible Volatility of Share Prices

   

     There is currently no established  public trading market nor has there been
any established public trading market for Company Stock. The Company anticipates
that the Company Stock shall initially be quoted in the "Pink Sheets". There can
be no assurance as to the prices at which Company Stock will be quoted after the
Distribution  Date.  Until  Company  Stock is fully  distributed  and an orderly
trading market develops (if one does),  the prices at which such stock is quoted
may  fluctuate  significantly.  The trading  price of the Company Stock could be
subject to wide  fluctuations  in response to variations  in operating  results,
announcements of technological  innovations or new products by the Company,  its
suppliers or competitors,  and other events or factors.  In addition,  in recent
years the stock  market has  experienced  large  price and volume  fluctuations,
which  often  have been  unrelated  to the  operating  performance  of  specific
companies or market  sectors.  These broad  market  fluctuations  may  adversely
affect the market price of the Company Stock.

         Although  the  Company  desires to achieve  the  listing of the Company
Stock on the Nasdaq SmallCap Market(sm),  the Company does not meet the standard
to qualify for initial listing on the Nasdaq  SmallCap  Market(sm) and there can
be no  assurance  that the Company  will meet such  requirements  in the future.
Thus, the Company Stock in all likelihood will be quoted in the over-the-counter
market  established  for  securities  that  do  not  meet  the  Nasdaq  SmallCap
Market(sm) listing 
    
                                        8

requirements,  and what is  commonly  referred  to as the  "Pink  Sheets."  As a
result,  an  investor  may find it more  difficult  to dispose  of, or to obtain
accurate quotations as to the price of, the Company Stock.

     In addition,  there is a significant  risk that the Company's Stock will be
subject to the so called  "penny  stock"  rules  that  impose  additional  sales
practice  requirements  on  broker-dealers  who sell such  securities to persons
other than established  customers and accredited investors (generally defined as
an investor with a net worth in excess of $1,000,000 or annual income  exceeding
$200,000 or $300,000  together with a spouse.) For  transactions  covered by the
penny stock rules, a broker-dealer must make a special suitability determination
for the purchaser and must have received the purchaser's  written consent to the
transaction prior to sale. Consequently,  both the ability of a broker-dealer to
sell the Company Stock and the ability of holders of Company Stock to sell their
securities in the secondary market may be adversely affected.

     The Securities and Exchange  Commission has adopted regulations that define
a "penny stock" to be an equity  security that has a market price (as defined in
the  regulations) of less than $5.00 per share or an exercise price of less than
$5.00 per share, subject to certain exceptions.  For any transaction involving a
penny  stock,  unless  exempt,  the rules  require  the  delivery,  prior to the
transaction,  of a disclosure  schedule relating to the penny stock market.  The
broker-dealer  must disclose the commissions  payable to both the  broker-dealer
and the registered representative, current quotations for the securities and, if
the broker-dealer is to sell the securities as a marker-maker, the broker-dealer
must  disclose  this  fact and the  broker-dealer's  presumed  control  over the
market.  Finally,  monthly  statements  must be  sent  disclosing  recent  price
information  for the penny  stock held in the  account  and  information  on the
limited  market  in penny  stocks.  As a result  of the  additional  suitability
requirements and disclosure requirements,  if the Company Stock is determined to
be "penny  stock,"  an  investor  may find it more  difficult  to dispose of the
Company Stock.

     The NASD requires  prospective  listing  applicants for the Nasdaq SmallCap
MarketSM to meet  certain  initial  listing  standards  and  continuing  listing
standards.  Additionally,  the  NASD  has  proposed  amendments  (the  "Proposed
Amendments") to the current listing criteria,  which if adopted,  would increase
the threshold amounts required for initial listing eligibility.  Generally,  the
initial  listing  standards as currently  set forth under the NASD  regulations,
require, among other things,  satisfaction of the following minimum requirements
with  respect to the issuer and the  security to be listed.  (Additionally,  the
Proposed Amendments are also discussed, to the extent applicable).

     (i)     The issuer must have total assets of not less than  $4,000,000  and
             capital and capital  surplus  (exclusive of certain  securities) of
             not less  than  $2,000,000.  Under  the  Proposed  Amendments,  the
             applicant must have either net tangible  assets of $4 million,  net
             income  of  $750,000  in two of the last  three  years,  or  market
             capitalization of at least $50 million;

     (ii)    The  common  stock  of the  issuer  must be held  by at  least  300
             shareholders and have a minimum bid price of $3.00 per share. Under
             the Proposed  Amendments,  the 300  shareholder  requirement  would
             remain the same,  although the minimum bid price would be increased
             to $4.00 per share;

     (iii)   At least  100,000  shares of the common stock of the issuer must be
             held by the  public,  and  must  have a  market  value  of at least
             $1,000,000.  Under the Proposed Amendments,  the number of publicly
             held  shares  would be  increased  to one million  shares,  and the
             required market value of such shares would be increased to at least
             $5,000,000; and

     (iv)    The common  stock of the issuer  must have at least two  registered
             and  active  market  makers,  one of which  may be a  market  maker
             entering a stabilizing  bid. The Proposed  Amendments would require
             that the common  stock of the  issuer  have at least  three  market
             makers.

     Additionally,  the Proposed  Amendments  would require the issuer to comply
with certain corporate  governance standards which are currently applicable only
to securities listed on the Nasdaq National Market, as well as maintain a market
capitalization of at least $50 million if the issuer has an operating history of
less than one year.

                                       9

     At March 31, 1997,  the Company's  financial  condition did not satisfy the
quantitative criteria for initial listing on the SmallCap Market as set forth by
the NASD concerning  total assets,  capital and surplus,  net tangible assets or
net income.
    

Decline in Defense and/or Aerospace Spending

     As a result of the decreased U.S. defense budget and spending over the past
few years, the manufacture of semiconductor and other electronic  components for
military and aerospace  applications  has been  shrinking,  and the military and
aerospace systems  manufacturers are experiencing a period of consolidation.  In
certain circumstances, this diminishing manufacturing supply in the military and
aerospace  industry  may be  beneficial  to the Company  because  the  Company's
services  are used to analyze  incidents  of  component  obsolescence.  However,
generally,  such  consolidation  makes  the  Company's  military  and  aerospace
customers  less stable and could  reduce the number of customers  and  potential
customers for the Company's services. Unless the Company is able successfully to
penetrate  the  commercial  and  industrial  market,  the decline in defense and
aerospace  spending  coupled  with  consolidation  in the defense and  aerospace
market and diminishing  manufacturer  supply for military  semiconductors  could
materially and adversely affect the Company.

     Approximately  95%  of  the  business  of  TACTech  derives  from  military
projects,   principally  through  sales  to  military,   defense  and  aerospace
contractors.  In the event that military, defense and/or aerospace spending were
to continue to decline  significantly or the diminishing  manufacturer supply of
semiconductors for military and aerospace  applications were to continue,  sales
by TACTech  could  suffer a  corresponding  or greater  decline.  In such event,
TACTech  would  have  to seek  replacement  markets  in  other  segments  of the
electronics  industry.  There can be no  assurance  that such  markets  would be
available or that TACTech would be successful in penetrating them.

     The number of military contractors that participate in defense type work is
rapidly decreasing  chiefly as a result of mergers and consolidation;  and thus,
the number of potential  military/defense  clients available that could make use
of the Company's  services is likewise  decreasing.  Additionally,  military and
aerospace  contractors  are  seeking  to  incorporate  a  larger  percentage  of
commercial/industrial components in the systems they produce. The development of
the Commercial Library to better service the Company's existing customers and to
protect the Company  from its current  dependence  on the  military  market will
require  significant  investment of effort and resources by the Company,  and is
subject to many uncertainties.

Dependence on Key Personnel

     The  businesses  of TACTech  are  substantially  dependent  upon the active
participation  and  technical  expertise of its executive  officers.  TACTech is
dependent upon Malcolm A. Baca, its Executive Vice President and Chief Operating
Officer. Zing currently maintains a key-man life insurance policy on Mr. Baca in
the amount of  $1,700,000.  Zing is entitled to receive 90% of the death benefit
under such policy. In connection with the Distribution,  it is contemplated that
such life  insurance  policy  will be  transferred  to the  Company  so that the
Company shall be the 90% beneficiary of the policy on Mr. Baca's life. There can
be no assurance,  however,  that the Company can obtain executives of comparable
expertise  and  commitment  in the event of death,  or that the  business of the
Company  would not suffer  material  adverse  effects as the result of the death
(notwithstanding  coverage  by  key-man  insurance),   disability  or  voluntary
departure  of  any  such  executive  officer.  The  Company  has  no,  and it is
contemplated that after the Distribution it will not have, insurance on the life
of Mr. Robert E. Schrader (the Company's  part-time  President,  Chief Executive
Officer and Chairman of the Board of  Directors).  However,  the business of the
Company is  substantially  dependant  upon Mr.  Schrader both as a result of the
services he performs directly for the Company and indirectly through Zing. After
the Distribution,  the Company's Board of Directors shall regularly  re-evaluate
the need for and amount of such key-man life insurance.

     Additionally,  TACTech's methodology utilized in the growth and maintenance
of its semiconductor libraries and data bases may depend under certain employees
and/or groups of employees.

     Under  certain  circumstances,  the loss of the services of Mr. Baca or Mr.
Schrader,  or the  departure of such  employees or groups could  materially  and
adversely affect the Company.

                                       10

Competition

     TACTech's  license  agreements  are cancelable on thirty (30) days' notice.
TACTech  competes  with  many  data  service  companies  which  possess  greater
financial and human resources than does TACTech.

     TACTech's  management  believes that TACTech  offers the only  commercially
available, continuously updated real-time, on-line information service dedicated
to tracking semiconductor  obsolescence and diminishing source management in the
electronic  component  industry.  However,  there can be no assurance that other
companies, including existing customers of TACTech, will not avail themselves of
sources of data to develop their own software and data base  services  either in
competition  with  TACTech or to enable  them to have their own sources for such
services.  TACTech's  software  services  and data bases are  protected by trade
secret provisions of license  agreements and by copyright laws, but because such
provisions and laws are frequently difficult or costly to enforce,  there can be
no assurance that such protection will prove effective.

     With  the  advent  of the  Internet  and the  World  Wide  Web,  electronic
manufacturers  may publish  information  about their  components  to the general
public as a service to their customers.  Although the Company's  management does
not believe such manufacturers  will behave in this manner,  such behavior could
materially and adversely affect the Company.

     The  market  for  the   Company's   data  services  is   characterized   by
technological  changes,  changing customer  requirements,  and evolving industry
standards.   The  introduction  of  competitive   products   incorporating   new
technologies  and the  emergence  of new  industry  standards  could  render the
Company's existing products obsolete or unmarketable.  The Company competes with
other  companies  which  offer  a  wide  array  of  information  services.  Such
competitors  may be  better  able to  afford  to  develop  sales  and  marketing
infrastructure  which the Company  believes is vital to survive in the shrinking
military  marketplace  and to gain entry to the  growing  commercial  industrial
marketplace. Many of such competitors already have dedicated direct sales forces
in the global  markets,  where the  Company  plans to develop and  increase  its
marketing presence.

     An integral  part of the  Company's  strategy is to expand its direct sales
force and to establish marketing and selling relationships both domestically and
internationally.  The  ability of the Company to achieve  revenue  growth in the
future   depends  on  its  success  in  adding   direct  sales   employees   and
representatives, and establishing marketing and selling relationships with other
organizations.  There  can be no  assurance  that  the  Company  will be able to
attract  sufficient  direct  sales  personnel,  or other  marketing  or  selling
partners to market the Company's services and products effectively. There can be
no assurance  that the cost of the  Company's  investment in direct and indirect
sales channels will exceed the revenue generated by such investment, or that the
Company's sales and marketing organization will successfully compete against the
sales and marketing organizations of the Company's competitors.

No Assurance that TACTech Can Continue
to Obtain Information to Update its
Database or Grow the Commercial Library;
Value Added Business

     Approximately  one-third of TACTech's  information for its data bases comes
from U.S.  Governmental  agencies and two-thirds from numerous  companies in the
private  sector.  There can be no  assurance  that  existing  arrangements  with
suppliers  of data from the private  sector will  continue in effect or, if they
are canceled,  that TACTech will be able to enter into  arrangements  with other
suppliers  on terms as  beneficial  to  TACTech  as those  presently  in effect.
Although  information  from U.S.  Governmental  agencies is generally  available
though  Freedom of  Information  Act  requests,  there can be no assurance  that
TACTech will continue to obtain sufficient data from U.S.  Governmental agencies
to conduct its business.

         Currently, the Company has good support from the military semiconductor
manufacturers  and is able  continually  to update its  military  and  aerospace
semiconductor  library to reflect current  changes on a near real-time,  on-line
basis. However, as the Company attempts to expand its services and penetrate new
markets,  there can be no assurance that the Company will be able to achieve the
same   degree   of   cooperation   from   industrial/commercial    semiconductor
manufacturers.  In addition, as the military and aerospace  semiconductor market
shrinks and the number of manufacturers servicing such market shrinks, there

                                       11
<PAGE>

can be no  assurance  that the  Company  will be able to  continue to update and
complement  its  military  semiconductor  library in an  appropriate  fashion to
continue to adequately service its military and aerospace customers. Duplicating
the  Company's  information  services  for  expansion  into the  commercial  and
industrial  market, as well as augmenting the Company's  existing  libraries and
data  bases  with  information  on  commercial/industrial  components  to better
service  existing  military and  aerospace  customers,  would  greatly  increase
maintenance  costs  to the  Company.  The  cost of  maintaining  the  Commercial
Library,  once it is built, is likely to be significantly  greater than the cost
of maintaining the Company's existing military library.

     Management   estimates  that  the  Company  has  obtained   information  on
approximately  75% of the  microcircuits  and 30% of the diodes and  transistors
which  management  believes  that the  Company  would have to obtain in order to
better  service  its  existing   military  and  aerospace   customers.   Of  the
approximately  250,000  commercial/industrial  semiconductors  available  in the
commercial/industrial  market, the Company's  management estimates that its data
bases  contain  information  on  approximately  16% of all of the  microcircuits
available  in the  commercial/industrial  market  and  approximately  12% of the
diodes and transistors  available in the  commercial/industrial  market. Thus, a
substantial  amount of new  information on  commercial/industrial  semiconductor
products must be obtained by the Company in order for the Company to achieve its
goals of better  servicing  its existing  military and  aerospace  customers and
sufficiently penetrating the commercial/industrial market.

     The Company's  management  believes that achieving the goal of developing a
Commercial Library in order sufficiently to penetrate the  commercial/industrial
market could  require at least 18 months.  There can be no  assurance  that such
goal can be reached in a timely manner.

     Moreover, as TACTech attempts to gain entry into global markets (Europe and
the  Far  East),   there  can  be  no  assurance  that  the  global   commercial
semiconductor  manufacturers  will support the Commercial  Library and cooperate
with  the  Company  in a manner  similar  to U.S.  semiconductor  manufacturers.
Advancements  in the  Internet  and World Wide Web sites may reduce the value of
information services that the Company offers because manufacturers may choose to
post  information  regarding  their own  products on the  Internet,  rather than
through the Company.  Although the Company believes that the Company's  services
are more desirable to customers than the review by customers of obsolescence and
specifications of their semiconductor products on a manufacturer-by-manufacturer
basis, if manufacturers  make information  available on the Internet rather than
through the Company,  this may decrease the value of the Company's libraries and
data bases and could result in a material and adverse effect on the Company.

     Since the Company's  services allow users to access  information which may,
in the future,  be made  available in the public  domain,  the Company  places a
great  emphasis on the  value-added  services it provides to  customers  such as
providing  software  tools to allow  customers  better to navigate the Company's
data  bases and  libraries.  There  can be no  assurance  that such  value-added
services would be perceived by customers to be valuable.

     Electronic equipment manufacturers in the military and aerospace market are
currently driving to incorporate a greater  percentage of commercial  components
in the systems they produce.  In order to continue to provide a valuable service
to the Company's military and aerospace customers, the Company must continuously
augment   the   existing    military   and    aerospace    data   library   with
commercial/industrial component information.

     Military   and   aerospace   contractors   increasingly   are   turning  to
commercial/industrial  manufacturers  of  semiconductors  for  components  to be
utilized  in such  contractors'  products.  This  migration  from  military  and
aerospace semiconductors to  commercial/industrial  semiconductors may lead to a
further decrease in the demand for information concerning military and aerospace
semiconductors.  Thus,  there  can  be no  assurance  that  unless  the  Company
effectively grows the Commercial Library (for use both by military and aerospace
customers and  commercial/industrial  customers)  that this  migration away from
military and aerospace  semiconductors  will not materially and adversely affect
the Company.

     There can be no assurance that the Company will be able to effectively grow
the  Commercial  Library.  The  development  of a  Commercial  Library  and  the
augmentation  of the Company's  existing  military  library with commercial type
information may be difficult to implement, be costly to the Company, and, if not
achieved, have a material adverse effect on the Company's future competitiveness
and profitability.

Utilization of Commercial/Industrial Information by the Company

     The  Company   believes  that  in  order   sufficiently  to  penetrate  the
commercial/industrial  market,  the Company must build the  Commercial  Library.
Although,  in the past,  the Company  has  successfully  integrated  information
regarding military and aerospace  semiconductors  with its proprietary  computer
software tools,  there can be no assurance that the Company will successfully be
able to integrate  information  regarding  commercial/industrial  semiconductors
with its  computer  software  tools.  The  failure to so  integrate  information
regarding  commercial/industrial  semiconductors  could materially and adversely
affect the Company.

Technological Change and New Product Development

     Rapid  technological  changes in the  semiconductor  industry are rendering
many industrial  semiconductor  components  obsolete.  The Company believes that
opportunities  for the Company's  services in the military and aerospace  market
are limited.  Thus,  the Company  believes  that the Company must  penetrate the
larger industrial/commercial market in order to reach its financial objectives.

     Currently,  TACTech provides services to customers'  personal computers via
telephone line  transmission  and over the Internet.  In the event of changes in
the structure of the computer  hardware  systems used by  subscribers to operate
TACTech's  data  base  software,  TACTech  would  incur  capital  costs  for new
equipment and  development  costs in connection  with the  reconfiguring  of its
software  programs,  which costs could be substantial  and could have an adverse
effect on TACTech's profitability. In addition, TACTech regularly incurs capital
costs in connection  with its new product  development in advance of their being
ready for market,  and there can be no  assurances  that such new products  will
prove profitable.

     There can be no assurance that the Company will be successful in developing
and marketing product enhancements or new products that respond to technological
change or evolving industry  standards,  or that the Company will not experience
difficulties   that  could  delay  or  prevent  the   successful   introduction,
development or marketing of these products.  Further,  there can be no assurance
that the Company's new product and product  enhancements will adequately address
the  requirements of the marketplace and thereby achieve market  acceptance.  If
the Company is unable to develop and introduce new products or  enhancements  of
existing  products in a timely manner, or if the Company  experiences  delays in
the introduction of new products or enhancements,  the Company may be materially
and adversely affected.

     Software  and  hardware  technologies  rapidly  change.  The  Company  must
continue to upgrade its hardware and software in order to  adequately  serve its
customers.  Moreover,  as the demand for the Company's services  increases,  the
Company must  continue to update its hardware and software in order to meet such
increased  demand.  There  can be no  assurance  that the  Company  will be able
adequately to meet such technological  advances. This failure may materially and
adversely affect the Company.

     The  Company's  management  believes  that in order to better  service  its
customers,  it will have to offer  more  value-added  services.  There can be no
assurance  that the Company  will be able to develop  and offer such  additional
value-added services like providing software tools to enable customers better to
navigate the Company's libraries and databases. Failure to so develop additional
value-added services may materially and adversely affect the Company.

Pricing Structure

     Currently, the Company charges a flat subscription fee for its services. As
telecommunications  technology  improves,  the  Company may desire to change its
pricing  structure  so that  charges  are  linked to the amount of time that the
Company's  services are accessed by its  customers.  The Company can not predict
whether  it  can  successfully  implement  such  a new  pricing  structure.  The
inability to implement a new pricing  structure  may  materially  and  adversely
affect the Company.

                                       13

Short Term, Terminable License Agreements; Dependence on Significant Customers.

     The Company's license agreements with its customers are generally for terms
of 12 months and may be  canceled  by either  party upon 30 days  notice.  Thus,
there can be no  assurance  that the Company  will be able to maintain  existing
subscription  levels and  customers.  In the event that  customers  cancel their
license agreements,  that Company may be materially and adversely affected since
the  Company  relies  on  the  subscriber  revenue  generated  by  such  license
agreements.

     A  significant  portion of the  Company's  revenues has  historically  been
derived  from large  sales to a limited  number of  customers,  including  Arrow
Electronics Inc. and Lockheed Martin Marietta  (where,  with respect to Lockheed
Martin Marietta, such revenue is generated from several Lockheed Martin Marietta
locations).  The loss of either of such  customers  (or of locations of Lockheed
Martin Marietta) may materially and adversely affect the Company.

Risks Associated with Emerging Internet Market

     A portion of the  Company's  strategy is to leverage  the  Internet and the
World Wide Web to provide  access to its services and  databases,  as well as to
additional  value-added content. The Company may devote substantial resources to
developing  products  designed for use with the Internet and the World Wide Web,
and there can be no assurance that the revenues generated,  if any, from the use
of the  World  Wide  Web or the  Internet  will  be  greater  than  the  cost of
developing and modifying products for such use. Further, the Company's solutions
may be rendered  obsolete by, or less  valuable in  comparison  to,  competitive
solutions made possible by future developments of the Internet in general or the
World Wide Web portion thereof specifically.  If this were to occur, the Company
would be materially adversely affected.

     There can be no assurance  that the  Company's  technology  will enable the
Company to meet increased demand for the Company's services through the Internet
generally and the World Wide Web specifically.  A failure to meet the demands of
changing technology could materially and adversely affect the Company.

Risk of Product Defects; Security Failure

     Software and  reference  data  products as complex as those  offered by the
Company  frequently  contain undetected errors or failures when first introduced
or when new  versions  are  released.  The  Company  has in the past  discovered
software bugs and data errors in certain of its products and enhancements,  both
before and after initial implementation. There can be no assurance that, despite
testing by the  Company and current  and  potential  customers,  errors will not
occur  in  products,   data  or  releases  after   commencement   of  commercial
applications,  resulting in loss of or delay in market  acceptance,  which could
have a material adverse effect on the Company.

     The  Company's  management  believes  that the Company  engages in adequate
security measures to protect the Company's  hardware,  software,  data bases and
libraries. See "Business of TACTech-Security  Measures." However, the failure of
security   measures  could   materially   and  adversely   affect  the  Company.
Additionally,  to the  extent  that such  security  measures  entail  the use of
encryption  technology not approved for export by the United States  government,
the  competitiveness of the Company in international  markets could be adversely
affected.

No Long Term Facility Lease

     TACTech is  currently  subletting  approximately  7,000 square fee in Yorba
Linda,  California from Arrow Electronics on a month-to-month basis at a cost of
$3,500.  Arrow  Electronics'  lease expires in November,  1997. TACTech believes
that its current  rental rate is below market and there can be no assurance that
TACTech can continue to lease suitable office space for its operations on a long
term basis at such a  favorable  rental  rate.  TACTech's  failure to locate and
lease adequate  facilities at a favorable  rent and for an appropriate  duration
could materially and adversely affect TACTech.

Certain Antitakeover Effects

   

     The  Company's  Amended and  Restated  Certificate  of  Incorporation  (the
"Company  Certificate") includes certain provisions that are intended to prevent
or delay  the  acquisition  of the  Company  by means of a tender  offer,  proxy
contest or  otherwise.  Specifically,  although  at present the Company has only
three  directors  serving on its board and  staggered  board  provisions  in the
Company Certificate are not yet effective, the Company Certificate provides that
while there are greater than three directors and fewer than seven directors, the
Board of Directors  shall be  classified  into two classes with the directors in
each class to serve staggered two year terms,  and where there are more than six
directors,  the Board of Directors  shall be classified  into three classes with
the  directors in each class  serving  staggered  three year terms.  The Company
Certificate fixes the size of the Board at not less than three nor more than ten
directors  with  the  exact  number  being  set by  resolution  of the  Board of
Directors.  In  addition,  the  Company  Certificate  authorizes  the  Board  of
Directors of the Company to issue preferred  stock without  further  stockholder
approval, which could have dividend, redemption, liquidation, conversion, voting
or other rights that could adversely  affect the voting power or other rights of
the holders of Company Stock.  Finally, the Company is subject to Section 203 of
the Delaware  General  Corporation  Law (the "DGCL")  which limits  transactions
between a publicly held company and "interested  stockholders"  (generally those
stockholders who, together with their affiliates and associates, own 15% or more
of a company's  outstanding capital stock). The anti-takeover  provisions of the
Company's  Certificate and By-laws are more  restrictive  than the DGCL. Any one
of, or a combination of, the above  anti-takeover  provisions could discourage a
third party from attempting to acquire control of the Company.  See "Description
of Capital Stock."

Control by Major Shareholder; Concentration of Stock Ownership

     Upon completion of the Distribution, Robert E. Schrader and Malcolm A. Baca
will own 230,542 and 55,383  shares,  respectively,  of the  Company  Stock,  or
approximately 41.6% and 10.0%, respectively, of the Company's voting securities.
Accordingly,  Mr.  Schrader  may be  deemed  to be a  controlling  person of the
Company.   The  Company's   management  and  directors  as  a  group  shall  own
approximately  296,096 shares, or 53.5%, of the issued and outstanding shares of
the Company Stock following the  Distribution.  Consequently,  Zing's management
and the directors will be able to exert significant  influence over the election
of the Company's  directors and the outcome of other corporate matters requiring
stockholder approval,  including changes in control of the Company. Mr. Schrader
is  employed  by the  Company  for a  three-year  period as its Chief  Executive
Officer,  Chairman of the Board and  President.  Since he is also the  principal
shareholder,  President,  Chief  Executive  Officer and Chairman of the Board of
Zing,  Mr.  Schrader  will be engaged  only  part-time  to the  business  of the
Company.  Under his  employment  agreement with the Company,  if Mr.  Schrader's
employment were to terminate  following a change in control of the Company,  Mr.
Schrader would be entitled to receive his remaining  salary plus  $250,000.  See
"Relationship With Zing; Potential Conflicts of Interest."

Shares Eligible for Future Sale

     After completion of the Distribution,  the 230,542 shares and 55,383 shares
of Company stock owned by Robert E. Schrader and Malcolm A. Baca,  respectively,
will be deemed to be  "restricted  securities"  within  the  meaning of Rule 144
("Rule  144") under the  Securities  Act of 1933,  as amended  (the  "Securities
Act").  The restricted  shares held by Mr. Baca will be eligible for sale by Mr.
Baca under Rule 144, as amended, since he has beneficially owned such shares for
more  than one  year,  subject,  however,  to  volume  limitation  and the other
restrictions  of Rule 144. The shares held by Mr.  Schrader will not be eligible
for sale under Rule 144 until one year following the Distribution, and will then
be subject to volume limitation and other restrictions of Rule 144. In addition,
Mr. Baca's shares are subject to further restrictions on the future sale of such
shares under a lock-up  agreement  contained in his  employment  agreement.  See
"Directors  and  Management of TACTech  -Employment  Contracts,  Termination  of
Employment  and  Change-In-Control  Arrangements."  The  Company  is  unable  to
estimate  the number of shares that may be sold in the future by Mr. Baca or the
effect,  if any,  that sales of  restricted  shares by Mr. Baca will have on the
market  price of the  Company  Stock  prevailing  from  time to  time.  Sales of
substantial amounts of Company Stock by Mr. Baca under Rule 144 or otherwise, or
even the potential of such sales, may have an adverse effect on the market price
of Company Stock. See "Description of Capital Stock - The Company Stock."

Potential Dilution

     Although  there are currently no  outstanding  options to purchase  Company
stock, pursuant to the Transition Analysis Component Technology, Inc. 1997 Stock
Option Plan (the "Option Plan"),  it is contemplated that after the Distribution
Date stock options will be issued.  Thus,  the ownership of Company stock may be
subject to significant dilution. See "Directors and Management of TACTech - 1997
Option Plan."

     The Company may file a registration  statement  under the Securities Act to
register an aggregate of 60,000  shares of Company  Stock  reserved for issuance
upon the exercise of stock  options  issuable  under the Option  Plan.  No stock
options have yet been granted under the Option Plan. However, upon the grant and
subsequent  exercise  of  such  stock  options,   the  shares  subject  to  such
registration  statement will be available for sale in the public market, subject
to Rule 144 limitations applicable to affiliates of the Company. Future sales of
shares of Company  Stock  issued  pursuant  to the Option  Plan could  adversely
affect the prevailing  market price of the Company Stock.  See  "Description  of
Capital Stock - The Company  Stock" and  "Directors  and Management of TACTech -
1997 Option Plan."

     In the future,  in connection  with achieving  TACTech's goal to enter into
strategic alliances and/or to make acquisitions to augment its business, TACTech
may issue shares of TACTech Stock or options to purchase  TACTech Stock to third
parties.  Any such  issuance  would  result in further  dilution of  outstanding
shares of TACTech Stock.

Important Considerations Related to Forward-Looking Statements

     With the exception of historical information, the matters discussed in this
document  may  include   forward-looking   statements  that  involve  risks  and
uncertainties.  The Company wishes to caution readers that a number of important
factors, including those identified in this section as well as factors discussed
elsewhere in this filing,  could affect the Company's  actual  results and cause
actual  results  to  differ   materially  from  those  in  the   forward-looking
statements. See "Special Note Regarding Forward-Looking Statements."

Dividends

     Management  of TACTech does not presently  intend to pay cash  dividends on
the Company Stock following the Distribution or in the foreseeable  future.  The
dividend  policy  will be  reviewed  from  time to time by  TACTech's  Board  of
Directors  based on  TACTech's  earnings,  financial  position  and  such  other
business considerations as its Board of Directors considers pertinent.
    
Certain Tax Considerations

   
     Zing  expects to  receive  an opinion  from Ernst & Young LLP to the effect
that it is more likely than not that the Distribution will qualify as a tax-free
distribution  pursuant to Section 355 of the Code. However, such opinion will be
based  upon  certain  representations  made by the  management  of Zing  and the
Company,  which have not been independently  verified, and is not binding on the
IRS or the courts.  No ruling has been or will be sought from the IRS  regarding
the tax  consequences  of the  Distribution.  Accordingly,  it is possible that,
notwithstanding  such opinion,  the Distribution  might not qualify for tax-free
treatment  under  Section  355 of the Code,  in which  case:  (i) Zing  would be
required to recognize  taxable gain on the  Distribution  equal to the excess of
the fair market  value of the  Company  Stock  distributed  over Zing's then tax
basis  in such  stock;  and  (ii)  the  Company  Stock  received  by  each  Zing
stockholder  would be treated as a dividend  taxable as ordinary  income to such
stockholder,  in an amount equal to the fair market  value of the Company  Stock
received by such stockholder. See "The Distribution--Certain  Federal Income Tax
Consequences of the Distribution."
    

Possible Lack of Liquidity

   
         As of March 31, 1997, the Company was indebted to Zing in the aggregate
amount of  approximately  $158,000  pursuant  to an existing  tax  reimbursement
arrangement  with Zing. The Company has reimbursed or will reimburse Zing for up
to  $100,000  of  expenses  incurred  by Zing in  connection  with the  costs of
preparing and filing the Company Registration  

                                       16

<PAGE>

Statements. TACTech's management is currently contemplating an expansion program
for the Company which would  include,  among other things,  expanding its direct
sales force,  establishing marketing and selling relationships both domestically
and  internationally,  developing  its  Commercial  Library,  and developing and
offering   additional   value-added   services  to  its  customers.   See  "Risk
Factors--Competition",  "--No  Assurance  that  TACTech  Can  Continue to Obtain
Information to Update its Database or Grow the Commercial  Library;  Value Added
Business",  "--Technological  Change".  While the Company has adequate liquidity
and  financial  resources  to fund its current  operations,  it may be unable to
generate  sufficient  cash and cash  equivalents to engage in all aspects of the
expansion  program  unless the Company is able to obtain a credit  facility from
one or more financial  institutions.  While the Company believes it will be able
to obtain such credit  facility  based on the  strength of Zing's  agreement  to
guaranty a portion thereof, there can be no assurance that it will be able to do
so. If the Company is unable to obtain a credit  facility,  it is likely that it
will be  required  to  significantly  reduce  the  scope  and or  timing  of its
expansion activities as currently contemplated by TACTech's management. Zing has
advised the Company that it will agree to guaranty repayment of up to $1,500,000
of principal  indebtedness  under one or more credit facilities with a financial
institution. See "Certain Transactions -- Zing Guaranteed Credit Facility."
     

Relationship with Zing; Potential Conflicts of Interest

     The Company does not have an  operating  history as an  independent  public
company.  The  operations  of the Company  historically  have relied on Zing for
certain necessary administrative services. As of the Distribution Date, Zing and
the Company will enter into several  agreements  and take certain  other actions
for purposes of governing certain of the ongoing  relationships  between the two
companies  following the Distribution,  including  indemnification  obligations,
management  services to be provided to the Company by certain current  employees
of Zing and Zing's  willingness to guaranty  repayment under a credit  facility.
Pursuant to the  Indemnification  Agreement  to be entered into between Zing and
the  Company  in  connection  with  the   Distribution   (the   "Indemnification
Agreement"),  the Company will agree to indemnify  Zing against all expenses and
liabilities  resulting  from (i) the operation of the Company from and after the
Distribution,  (ii)  Zing's  operations  of  TACTech's  business  prior  to  the
Distribution   other  than  those  based  upon  the  tax   consequences  of  the
Distribution  and (iii) any claim,  suit or other type of proceeding based upon,
arising out of or in connection with any  information  concerning the Company in
this  prospectus  or any  information  furnished by the Company  concerning  the
Company for inclusion in this  prospectus;  and Zing will  indemnify the Company
for any claims incurred or suffered,  directly or indirectly,  by them resulting
from or attributable to, among other things (i) the operation of Zing from after
the  Distribution  and (ii) any claim,  suit or other type of  proceeding  based
upon,  arising out of or in  connection  with the  operation of Zing's  business
(other than the  Company's  business)  prior to the  Distribution  and (iii) any
claim,  suit or  other  type of  proceeding  based  upon,  arising  out of or in
connection  with  any  information  concerning  Zing in this  prospectus  or any
information  furnished by Zing concerning Zing for inclusion in this prospectus.
Although  the  Company  is not  aware  of any  pending  or  threatened  material
liability for which the Company anticipates  becoming obligated to make payments
in connection with its obligations to indemnify Zing,  there can be no assurance
that   such   indemnification   obligations   could   not  arise  or  that  such
indemnification  obligations would not be material to the Company). See "Certain
Transactions - Indemnification Agreement."

   
         The  Company  will  engage  certain  current  employees  of  Zing  on a
part-time basis to render to the Company the following management services for a
cost not expected to exceed  $100,000 per year: to advise in the  development of
the  Company's  business  plan,  to advise the  Company  with  respect to and to
negotiate   material   agreements  on  the  Company's   behalf,   to  coordinate
communications  with the  Company's  stockholders,  to advise the  Company  with
respect to and to negotiate prospective acquisitions and financings,  to prepare
and file the Company's tax returns and reports required by applicable securities
laws and rules of  applicable  stock  exchanges,  to review  and  supervise  the
Company's  accounting  department  and  systems  from  time to time and  suggest
revisions and changes thereto,  to perform  supervisory  financial and strategic
analysis services, and to perform such further services as agreed by the Company
and Zing.  See  "Certain  Transactions  --  Management  Services."  A  potential
conflict of interest  could arise if such Zing  employees  were unable to render
such  management  services to the Company as a result,  among other  things,  of
conflicting  instructions from the Board of Directors of Zing in connection with
any  transactions  between  the  Company  and  Zing  (as,  for  example,  Zing's
willingness to guaranty TACTech's  indebtedness  pursuant to a credit facility),
or of Zing's  willingness  to make such  persons  available  to the Company when
needed.

     Additionally,  Zing has  informed  the Company  that it will provide to the
Company credit enhancement in the form of a guaranty of repayment by the Company
of its obligations under a credit facility of up to $1,500,000 principal amount.
However, there can be no assurance that those members of the Company's Board

                                       17

<PAGE>

of Directors  who also serve on Zing's Board of Directors  will  exercise  their
discretion in their Zing capacity for the benefit of the Company with respect to
the terms of a guaranteed  credit  facility if they conclude that such is not in
Zing's best  interests.  See  "Certain  Transactions  - Zing  Guaranteed  Credit
Facility."
     

     These  agreements and  arrangements  were negotiated  while the Company was
owned by Zing and consequently  are not the result of arm's-length  negotiations
between  independent  parties.   Nonetheless,  the  Company  believes  that  the
agreements are fair to the Company and contain terms which are no less favorable
to the Company than could be obtained as a result of arm's-length  negotiations,
although there can be no assurance thereof. See "Certain Transactions."

     Under his  employment  agreement  with the Company,  Mr.  Schrader  will be
entitled to receive  substantial  compensation  should his employment  terminate
following a change in control of the Company.  Since Mr. Schrader is effectively
in control  of the  Company,  he may have the  ability to cause such a change in
control.

                                THE DISTRIBUTION

Background of the Distribution

     The  Distribution  is being  undertaken by Zing because  Zing's  management
believes that, after giving effect to the Distribution,  TACTech will be able to
more  readily  obtain  equity  financing  and  use  its  capital  stock  to make
acquisitions;   investors   will  be  better  able  to  evaluate  the  financial
performance  of TACTech,  thus  enhancing  the  likelihood  that it will achieve
appropriate  market  recognition  and will  increase  over  time the value of an
investment  in the  respective  companies;  and  TACTech's  Management  will  be
provided with an incentive  (through  existing stock ownership and future grants
of stock  options) to increase the market value of TACTech while  simultaneously
imposing  direct  accountability  to public  investors for TACTech's  management
policies and financial results.

Manner of Effecting the Distribution

     Pursuant to the  Distribution,  Zing will distribute to its stockholders of
record as of the Record Date one share of Company Stock,  after giving effect to
the Stock  Split,  for each five (5)  shares of Zing  Stock  then  held.  On the
Distribution Date, Zing will deliver to the Transfer Agent,  Zing's Distribution
Agent in connection with the  Distribution,  certificates  evidencing all of the
issued  and  outstanding  shares of  Company  Stock  owned by Zing,  which  will
represent 90% of the issued and outstanding  shares of Company Stock. All shares
of Company  Stock  distributed  will be fully  paid,  nonassessable  and free of
preemptive rights.

   
     As a result of the Distribution,  90% of the issued and outstanding  shares
of Company  Stock  will be  distributed  to  persons  who hold Zing Stock on the
Record Date, with the remaining 10% being owned by the Company's  Executive Vice
President,  Malcolm Baca. The Record Date is June 17, 1997, and the Distribution
Date  will be as soon as  practicable  following  the  Securities  and  Exchange
Commission's   declaration  of   effectiveness   of  the  Company   Registration
Statements.  It is presently anticipated that certificates  representing Company
Stock  will be mailed to  eligible  Zing  stockholders  promptly  following  the
Distribution Date. The Distribution will not affect the number of, or the rights
attaching to, outstanding shares of Zing Stock.
    

     No  holder  of  Zing  Stock  will be  required  to pay  any  cash or  other
consideration  for the shares of Company Stock received in the  Distribution nor
will any action be required to be taken by any such holder,  including tendering
stock  certificates,  in order to  receive  shares of Company  Stock.  Zing will
account for the  Distribution  as a dividend  and will reduce its  stockholders'
equity by the net book value of the Company Stock distributed.

     No certificates or scrip  representing  fractional  shares of Company Stock
will be issued as part of the  Distribution.  The Transfer  Agent will aggregate
fractional  shares into whole  shares and sell them back to the Company  shortly
after the Distribution Date on behalf of holders who otherwise would be entitled
to receive fractional share interests.  Such persons will instead receive a cash

share interests.  Fractional share interests will be purchased by the Company at
the  average of the high and low bids  quoted for the  Company  Stock on the day
after the Distribution.

     Most  expenses of the  Distribution  will  initially  be paid by Zing.  The
Company,  however,  has  reimbursed  or has  agreed to  reimburse  Zing for that
portion of such  expenses  pertaining  directly  to the costs of  preparing  and
filing the Company Registration Statements, up to a maximum amount of $100,000.

     IN ORDER TO BE ENTITLED TO RECEIVE THE  DISTRIBUTION  OF COMPANY  STOCK,  A
ZING STOCKHOLDER  RECEIVING THIS PROSPECTUS MUST HAVE BEEN A HOLDER OF RECORD OF
ZING STOCK ON THE RECORD DATE.

Listing and Trading of Company Stock

   
     The  Company  anticipates  the  Company  Stock  will be quoted in the "Pink
Sheets" under the symbol  "TRZA"  following the  Distribution.  Paragon  Capital
Corp.  has agreed to act as a market maker for the  Company's  Stock.  See "Risk
Factors  -Absence of Trading Market for Company Stock;  Requirements for Listing
on Nasdaq SmallCap  Market(sm);  Application of Penny Stock Rules." The transfer
agent and registrar for the Company Stock is The Bank of New York.

     No current public  trading market for the Company Stock exists,  although a
"when-issued"  market could develop several days prior to the Distribution Date.
The  extent of the  market  for the  Company  Stock and the  prices at which the
Company  Stock  may be  quoted  prior to or after  the  Distribution  cannot  be
predicted.  See "Risk  Factors -- Absence of Trading  Market for Company  Stock;
Requirements  for Listing on Nasdaq  SmallCap  Market(sm);  Application of Penny
Stock Rules."
     

     The Company Stock  distributed to the stockholders of Zing as of the Record
Date will be freely  transferable,  except for Company Stock received by persons
who may be deemed to be  "affiliates"  of the Company under the Securities  Act.
Persons who may be deemed to be affiliates of the Company after the Distribution
generally include individuals or entities that control, are controlled by or are
under  common  control  with the Company and may include  certain  officers  and
directors  of the  Company as well as  principal  stockholders  of the  Company.
Persons  who are  affiliates  of the  Company  will be  permitted  to sell their
Company Stock only  pursuant to an effective  registration  statement  under the
Securities  Act  or an  exemption  from  the  registration  requirements  of the
Securities  Act,  such  as  the  exemptions  provided  by  Section  4(1)  of the
Securities Act or Rule 144 thereunder.  It is not expected that Rule 144 will be
available  for the sale of Company  Stock by  affiliates of the Company until at
least 90 days after the  effectiveness of the Company's  registration  statement
registering  Company Stock under the Exchange Act. See  "Description  of Capital
Stock -- The Company Stock."

Certain Federal Income Tax Consequences of the Distribution

         General.  The  following is a summary  description  of certain  Federal
income tax consequences of the Distribution to Zing and to the holders of shares
of Zing Stock. The summary set forth below is for general information only, does
not purport to cover all potential Federal income tax consequences,  and may not
apply to  particular  categories  of holders of shares of Zing Stock  subject to
special treatment under the Code, including without limitation,  foreign holders
and holders whose Zing securities were acquired  pursuant to the exercise of any
employee stock option or otherwise as compensation. The discussion is based upon
the Code,  applicable Treasury  Regulations  thereunder,  judicial decisions and
current  administrative  rulings and practices,  all as in effect on the date of
this  prospectus,  and does not address any state,  local,  or foreign income or
other tax consequences of the Distribution. No rulings from the Internal Revenue
Service have been requested concerning such tax consequences.

     ACCORDINGLY  EACH HOLDER OF SHARES OF ZING STOCK IS ADVISED TO CONSULT SUCH
HOLDER'S TAX ADVISOR AS TO THE SPECIFIC TAX  CONSEQUENCES  TO SUCH HOLDER OF THE
DISTRIBUTION,  INCLUDING THE APPLICATION AND EFFECT OF STATE,  LOCAL AND FOREIGN
INCOME AND OTHER TAX LAWS.

     Tax  Consequences of the  Distribution.  Zing expects to receive an opinion
from Ernst & Young LLP to the effect  that it is more  likely  than not that the
Distribution,  for Federal income tax purposes,  should be treated as a tax-free
spinoff  pursuant to Section 355 of the Code. The tax opinion will be based upon
the Code and authorities interpreting the Code as of the date of the issuance of
such opinion. The tax opinion will not be updated for any changes to the Code or
authorities  interpreting the Code that may occur after the date of the issuance
of such  opinion  and  assumes  that the  Distribution  will be  consummated  as
described  herein.  It should be noted that no ruling has been sought or will be
sought from the IRS regarding the Distribution. Neither this summary nor the tax
opinion is binding on the IRS or the courts,  and consequently,  there can be no
assurance  that the IRS or a court  will agree  with the  conclusions  expressed
herein or in the tax  opinion.  The  delivery of the tax opinion is  conditioned
upon (i) the receipt of certain representations to be made by the managements of
Zing and the Company,  and certain other data,  documentation,  and materials as
deemed necessary (including the information contained in this prospectus),  none
of which has been independently  verified by Ernst & Young LLP, and (ii) certain
limitations set forth therein.
    

     It is expected that the tax opinion will state that,  more likely than not,
the Distribution should qualify as a tax-free  distribution under Section 355 of
the Code and, consequently, the following Federal income tax consequences should
result:

     1. A Zing stockholder should not recognize any taxable income, gain or loss
as a result of the receipt of Company Stock in the Distribution.

     2. Following the Distribution,  a Zing stockholder should apportion the tax
basis of such stockholder's shares of Zing Stock between such Zing Stock and the
Company Stock  received in the  Distribution  in proportion to the relative fair
market values of such Zing Stock and Company Stock on the Distribution Date.

     3. A Zing  stockholder's  holding  period for the Company Stock received in
the  Distribution  should include the period during which such  stockholder held
the Zing Stock with respect to which the Company  Stock was  received,  provided
that such Zing Stock is held as a capital  asset by such  stockholder  as of the
time of the Distribution.

     4. No income,  gain or loss should be recognized by Zing as a result of the
Distribution.

   
     Ernst & Young LLP's opinion with respect to the Distribution  will be based
upon certain  representations of fact made by the management of Zing, which have
not been independently  verified, and is not binding upon the IRS or the Courts.
If any representation  relied upon by Ernst & Young LLP in rendering its opinion
should prove to be inaccurate,  or if the IRS were to challenge successfully the
Federal income tax treatment of the  Distribution  as set forth in such opinion,
then, in general,  although not entirely free from doubt, for Federal income tax
purposes  it is  likely  that the  Distribution  will be  treated  as a  taxable
transaction both to Zing and the Zing  stockholders.  In such event,  Zing would
recognize  gain equal to the  difference  between the fair  market  value of the
Company Stock and Zing's tax basis in such Company Stock. The Distribution would
also  be  considered,   for  Federal  income  tax  purposes,  to  be  a  taxable
distribution  to the Zing  stockholders  with respect to their Zing Stock.  Such
distribution  would be  characterized  for  Federal  income  tax  purposes  as a
dividend (to the extent of Zing's current and accumulated  earnings and profits,
which  can be  expected  to be  equal  to or  exceed  the  total  amount  of the
Distribution)  equal in amount to the fair  market  value of the  Company  Stock
received.  For purposes of calculating  gain to Zing and the dividend  amount to
the Zing  stockholders,  the fair market value of the Company Stock is generally
considered  to be the mean  between the high and the low  trading  prices of the
Company Stock on its first day of trading  following the  Distribution.  The tax
basis of the shares of  Company  Stock  received  by a Zing  stockholder  in the
Distribution  would be equal to such fair  market  value of such  shares and the
holding  period for such  shares of Company  Stock would begin the day after the
Distribution Date.
    

     Current  Treasury  Regulations  require  that  each  Zing  stockholder  who
receives Company Stock pursuant to the Distribution attach to such stockholder's
Federal  income  tax  return  for the year in which  the  Distribution  occurs a
detailed statement setting forth such information as may be appropriate in order
to demonstrate the applicability of Section 355 of the Code to the Distribution.
Zing will convey the appropriate  information to each Zing stockholder of record
as of the Record Date.

     Proposed  Legislation.  On April 16, 1997,  legislation was introduced that
would  change  certain  provisions  of  existing  Section  355 of the Code.  The
proposed  legislation  generally  would provide that if, pursuant to a "plan" or
"arrangement" or

                                       20

<PAGE>

"series of related transactions" in existence on the date of the distribution of
a controlled  subsidiary,  either the controlled  subsidiary or the distributing
corporation is acquired after the distribution, taxable gain would be recognized
by the other (non-  acquired)  corporation  as of the date of the  distribution.
Acquisitions occurring during the period commencing two years before, and ending
two years after, a distribution  would be presumed to have occurred  pursuant to
such a "plan" or "arrangement" or "series of related transactions".  If enacted,
this proposal  would be effective for  distributions  occurring  after April 16,
1997, with certain limited  exceptions.  Accordingly,  in the event the proposed
legislation  is adopted in its present  form, in the case of an  acquisition  of
Zing  pursuant  to  such  a  "plan"  or  "arrangement"  or  "series  of  related
transaction" in existence on the date of the Distribution,  the Company would be
required to  recognize  taxable gain in an amount equal to the amount of the net
gain that Zing would  hypothetically have realized had it sold all of its assets
for their fair market value on the date of the Distribution.  Such gain would be
taxed to the Company as long term capital gain, but no adjustments would be made
to the tax bases of the stock or assets of either  Zing or the Company by reason
of such gain recognition.

     The management of Zing has  represented to Ernst & Young LLP that they know
of no  existing  "plan" or  "arrangement"  or "series  of related  transactions"
pursuant to which a person will acquire  stock  representing  50% or more of the
stock  of  Zing  or  the   Company   after  the   Distribution.   However,   if,
notwithstanding  such  representation,  a person  should  acquire 50% or more of
Zing's  stock  or the  Company's  stock in the  two-year  period  following  the
Distribution, such a "plan" or "arrangement" or "series or related transactions"
will be presumed to have existed,  and  significant  tax liability to Zing or to
the Company would result unless such presumption could be successfully rebutted,
as to which there can be no assurance.

Certain Consequences of the Distribution

     After the  Distribution,  Zing stockholders of record as of the Record Date
and the  Distribution  Date will own two  securities  (shares  of Zing Stock and
shares  of  Company  Stock)  and  will be able to  increase  or  decrease  their
respective  holdings  in either  Zing or the  Company  without  affecting  their
holdings in the other company. The Company will be an independent, publicly held
company.

Reason for Furnishing this Prospectus

     This  prospectus  is being  prepared  in order to provide  information  for
holders of shares of common stock of Zing,  each of whom will receive  shares of
Company Stock in the Distribution as well as future investors in the Company. It
is not to be  construed as an  inducement  or  encouragement  to buy or sell any
securities of Zing, the Company or any other entity.  The information  contained
herein is provided as of the date of this prospectus unless otherwise indicated.
Neither  Zing nor the Company  will  update the  information  contained  in this
prospectus  to effect any changes that may occur  subsequent to the date hereof,
except in the normal course of their respective public disclosure practices.

Results of Operations -  Nine Months Ended  March 31,  1997
Compared To  Nine Months Ended  March 31,  1996

     TACTech generates  revenues  primarily  through license  agreements for its
data base services.  These agreements are generally for terms of 12 months,  but
may be canceled by either party upon 30 days'  notice.  The number of subscriber
licenses  generating revenues was greater by approximately 30% at March 31, 1997
as compared to March 31,  1996.  The  following  data  indicates  the  licensing
activity for each period:

     TACTech  earned net income of  $212,790  or $0.38 per share  (after  giving
effect to the Stock Split), for the nine months ended March 31, 1997 compared to
$96,764 or $0.17 per share (after  giving  effect to the Stock  Split),  for the
nine months ended March 31, 1996.

     Revenues  for the nine  months  ended  March 31,  1997 were  $1,606,934  as
compared  to  $1,183,505  for  the  nine  months  ended  March  31,  1996.  This
represented an increase of 36% for the nine months ended March 31, 1997 over the
prior comparable  period.  The increase in revenue is primarily  attributed to a
combination of a larger  subscriber base, and a general increase in subscription
services as subscribers renew.

     Selling,  marketing,  software  development  and  maintenance  expense  and
depreciation  increased to  $1,302,944  for the nine months ended March 31, 1997
from $1,045,341 for the prior  comparable  period.  The increase is attributable
primarily  to  increases in personnel  costs as  demonstrated  by the  following
table,  and,  to a lesser  extent,  by an increase  in  administrative  overhead
charges from Zing, the parent company:

     In Fiscal 1996 subscriber gains were approximately 50% more than the losses
and in Fiscal 1995 the ratio was  approximately  33%.  Approximately  81% of the
subscriber licenses expiring were renewed as compared to 77% in Fiscal 1995.

     TACTech  earned net income of $107,186,  or $0.19 per share  (after  giving
effect to the Stock Split), for the Fiscal Year ended June 30, 1996, compared to
$38,325,  or $0.07 per share (after giving  effect to the Stock Split),  for the
Fiscal Year ended June 30, 1995.

     Revenues  for the  Fiscal  Year  ended  June 30,  1996 were  $1,601,255  as
compared to $1,224,656 for the Fiscal Year ended June 30, 1995.  This represents
an increase of 31% over the prior comparable period.

     Selling,  marketing,  software  development  and  maintenance  expenses and
depreciation  increased to $1,444,000 for the Fiscal Year ended June 30, 1996 as
compared to $1,170,000  for the Fiscal Year ended June 30, 1995. The increase is
primarily  attributable to a $200,000 increase in personnel costs as a result of
the Company's  expanded  operations.  The following  schedule  demonstrates  the
growth in personnel additions by functional area:

Trends

   

     TACTech's  intention is to position  itself to  capitalize  on the need for
more efficient  design  service as the  Department of Defense budget  contracts.
Although a declining U.S. military budget may result in a reduction in the total
number or dollar value of military projects, TACTech believes that Department of
Defense  imperatives  aimed at design  efficiency  for those  projects will make
TACTech's  services  more  valuable  as a means of  reducing  the  incidence  of
technological  obsolescence  and  assisting  designers in  identifying  the best
available  military  industrial  practices.  The  Company  does  not  anticipate
material  changes in its operating  methods or future  financial  condition as a
direct result of becoming a standalone company,  except that the Company will in
the future accrue interest  expense for capital borrowed from Zing or from third
parties. Additionally, the Company will capitalize the approximately $514,000 in
long-term liabilities due to Zing.

     Administrative  expenses  for the nine  months  ended  March 31,  1997 have
increased in anticipation of the  Distribution,  largely as a consequence of the
allocation  to the  Company of the  expense  arising  from  management  services
rendered by certain Zing employees to the Company,  and the expense arising from
the  employment  agreement with the Company's  president.  Such expenses are not
expected to materially increase following the Distribution.

    

Liquidity and Capital Resources

     In fiscal 1996 and 1995,  the Company used most of its cash  generated from
operations for the acquisition of computers and computer related equipment,  and
for the reduction of its  obligations to Zing and generally for business  growth
and development.

     As of  July 1,  1996,  the  Company  was  party  to  customer  subscription
agreements that, assuming no cancellations,  in the opinion of management,  will
generate approximately $2,000,000 in revenue for the fiscal year ending June 30,
1997.  Together  with  borrowings  under the Zing  Guaranteed  Credit  Facility,
internal  cash  flow  generated  by the  operations  of the  Company  should  be
sufficient for the Company to meet its short-term  working capital  requirements
and capital expenditure  requirements  provided there are no unduly large number
of cancellations in customer  subscription  agreements.  TACTech's management is
currently  contemplating  an  expansion  program  for the  Company  which  would
include,  among other  things,  expanding  its direct sales force,  establishing
marketing  and selling  relationships  both  domestically  and  internationally,
developing  its  Commercial  Library,  and  developing  and offering  additional
value-added services to its customers.  See "Risk  Factors--Competition",  "--No
Assurance that TACTech Can Continue to Obtain Information to Update its Database
or Grow the Commercial Library; Value Added Business", "--Technological Change".
While the Company has adequate  liquidity  and  financial  resources to fund its
current  operations,  it may be  unable  to  generate  sufficient  cash and cash
equivalents to engage in all aspects of the expansion program unless the Company
is able to obtain a credit  facility  from one or more  financial  institutions.
While the Company  believes it will be able to obtain such credit facility based
on the strength of Zing's agreement to guaranty a portion thereof,  there can be
no assurance that it will be able to do so. If the Company is unable to obtain a
credit facility,  it is likely that it will be required to significantly  reduce
the scope and or timing of its expansion activities as currently contemplated by
TACTech's management. In addition, although there are no present understandings,
commitments  or  agreements   with  respect  to  any  acquisition  or  of  other
businesses, products or technologies or any strategic alliances, the Company may
from time to time evaluate  potential  acquisitions of businesses,  products and
technologies or strategic alliances


                                       25

<PAGE>

and may in the future require additional equity or debt financings to consummate
such potential acquisitions or strategic alliances.

Impact of Inflation

     In 1996 and  1995,  inflation  did not  have a  significant  impact  on the
operations of the Company.  Since the  Company's  licensing  contracts  with its
customers are for relatively short periods, inflation may have an adverse effect
on the Company's revenues and pricing structure.

                               BUSINESS OF TACTECH

General

   

     TACTech is a semiconductor  information  service  company,  incorporated in
Delaware in 1987, which licenses  proprietary  computer  software tools combined
with  electronic  semiconductor  availability  libraries and data bases that are
utilized by various segments of the Department of Defense,  defense contractors,
industrial  users of high  reliability  semiconductors,  and  manufacturers  and
distributors  of  high  reliability  and  military  grade  semiconductors.  When
accessed by customers,  the libraries  and data bases provide  subscribers  with
valuable  tools  for   determining   semiconductor   availability   showing  the
manufacturers  actively  producing  subject  semiconductors  and  the  projected
production  life  cycle  (obsolescence)  for  such  semiconductors.  The  system
identifies functionally  interchangeable  devices, when available,  from various
manufacturers.  At present,  the Company's libraries and data bases are utilized
by its  customers  primarily  in  connection  with the  designing,  engineering,
manufacturing  and  maintaining  of  electronic  systems  for  high  reliability
applications.  As of March 31,  1997  TACTech  services  were  subscribed  to by
ninety-two (92) customers located  throughout the United States and Canada;  and
three (3) customers outside the continental United States.  Approximately 95% of
the  Company's  revenue  derives  from  military  projects,   primarily  through
government  contractors  and  subcontractors.   Government  agencies  themselves
account for less than 10% of the Company's revenues in the aggregate.

    

     The  TACTech  data bases  libraries  contain the  nomenclature  and general
description for over 190,000 individual military  semiconductor  devices, and is
believed by  management  to include  virtually  all standard  microcircuits  and
discrete  devices  with  military  specifications.  The data base is  constantly
updated at TACTech's  headquarters and delivered on a real-time,  on-line basis.
TACTech  software  provides a  description  and  general  specification  of each
microcircuit  and discrete device in the TACTech  library,  thereby allowing the
user to identify functionally interchangeable devices from various manufacturers
and to  upgrade  and  rank  devices  according  to  packaging,  quality  levels,
projected  production life cycle and availability based on changes in technology
and sources of supply. All semiconductors listed in TACTech's library are ranked
by  reference  to such  factors.  The  Company's  management  believes  that the
Company's existing data bases and libraries are accurate and comprehensive.

     TACTech has  developed  proprietary  analysis  procedures  and  software to
provide a production  life cycle  projection  assessment  rating for each device
type (microcircuit,  diode and transistor)  contained in its library.  TACTech's
production  life  cycle   projections   are  determined  by  tracking   specific
device-type  attribute values such as speed, density,  packaging,  manufacturing
process, design-in acceptance and available sources of supply.

     TACTech's  proprietary software allows its customers to receive information
from TACTech's library in useable formats through a personal computer with modem
access or through the Internet.  The system  allows for device type  information
searches to be  conducted on a form-fit  and  function  equivalent  basis and/or
alternate  technology  basis.  Updates  to  TACTech's  information  library  are
available to TACTech's  customers on a  real-time,  on-line  basis.  Information
searches  can be  conducted  by the  customer on a base number  search,  through
parametric product description and by generic part number identification.

     TACTech  continually  updates its library with  information  that  includes
product introductions,  product discontinuances and changes in the quality level
or packaging of available  products.  The TACTech system permits  subscribers to
conduct


                                       26

<PAGE>

individual  device type  searches or to conduct an analysis on an entire bill of
materials for semiconductor  devices.  TACTech provides an automatic  electronic
discontinuance   notification  service  through  its  built-in  software,  which
automatically  notifies the subscriber of changes in semiconductor  availability
with reference to specific subscriber's bill(s) of materials.

     TACTech  also   maintains  a  "where  used"  library  which   contains  the
semiconductor  content in over 2,000  unclassified  military  electronic  system
variations.  A user can access  this "where  used"  library to  determine  which
specific device types are  incorporated  within specific systems or to determine
how many electronic  military  systems use a given  semiconductor.  "Where used"
information  is  particularly  valuable  to  semiconductor   manufacturers,   or
electronic  components parts distributors,  in determining marketing strategy or
analyzing device type usage trends within unclassified military applications.

     In recent years the U.S.  Government has effected defense budget reductions
while at the same time establishing  procurement  policies aimed at cost control
and  efficiency.  The  Department of Defense is encouraging  its  contractors to
constantly analyze trends of potentially  diminishing  manufacturing sources and
technological   obsolescence  as  important  considerations  when  designing  or
maintaining new electronic  systems.  The TACTech systems allows contractors and
designers  to  screen  out  obsolete  semiconductors  and  provide  for the more
predictable manufacture and better maintenance of equipment, thus helping ensure
a longer operational life of equipment.

   

     The  Department of Defense has been  emphasizing  that military  electronic
system  designs are to be  developed  utilizing  the best  commercial/industrial
practices  in order to control or reduce  cost while at the same time  expanding
design options  without  degrading  system  reliability.  In accordance with the
mandate for the application of best  commercial  /industrial  practice,  defense
contractors and subcontractors have become increasingly  interested in exploring
the use of reliable industrial or commercial components and process technologies
as favorable  alternatives to previous standard "MilSpec only" designs.  TACTech
believes  that the trend  which  emphasizes  alternative  design  concepts  will
continue and that issues of component obsolescence and management of diminishing
sources  relating  to  standard  military  designated   components  will  be  an
increasing  problem facing the military  electronics  industry,  thus creating a
growing market for the services offered by TACTech.
    
     In  addition  to  projecting  the  production  life cycle of  military  and
aerospace  semiconductors and providing information on technological updates and
source  changes  for  military  and  aerospace  devices,   TACTech  provides  an
information service that allows the user to convert most military  specification
semiconductors to their closest industrial  equivalent.  The conversion is based
on electrical functionality as well as packaging availability.  TACTech believes
that this data service will prove to be of significant value to its customers.

         Another facet of TACTech's collective  information service is the value
that the service has to design engineers during the component  selection process
to screen out obsolete technologies. This facet is important to design engineers
when they take into account after market/spares support in the design process.

     Although in certain  circumstances  the  contraction  of the  military  and
aerospace semiconductor  manufacturing market may be harmful to the Company, the
related shift in  procurement  philosophy in the military and aerospace  markets
creates  favorable  market  conditions  for the Company in the short  term.  The
diminishing  manufacture  supply,  coupled  with  advancement  and  evolution of
semiconductor  products,  leads  to  increased  component  obsolescence  in  the
military and  aerospace  markets.  New product  developments  and the desire for
efficiency in the areas of functionality,  speed,  density,  power reduction and
packaging  have led to the  advent of low power  technologies  in  semiconductor
design.  New generations of such low power  semiconductor  devices require their
own compatible  power supplies.  Thus,  complete circuit design dedicated to the
use of such lower power semiconductor devices is required, thus rendering older,
higher power circuitry obsolete.

     The   Company's   management   believes   that  the  advent  of  low  power
semiconductor   technology,   together   with   the   continued   evolution   of
semiconductors,   will  increase  the  obsolescence  of  semiconductor  devices.
Military and aerospace contractors  dependent upon existing  semiconductors will
require  the  services  of the Company as such  existing  semiconductors  become
obsolete on an accelerated basis. Such contractors should be forced to adapt and
implement   strategies   which  will  allow  them   timely  to  track   changing
semiconductor technology.


                                       27

     The Company's objectives are: (i) the augmentation of the existing military
and aerospace library to include applicable commercial  industrial  information;
(ii) the building of the Commercial  Library to a level  sufficient to penetrate
the  commercial/industrial  market while maintaining the Company's  military and
aerospace  business;  (iii)  increasing the Company's  sales force and marketing
efforts to better  position the Company to penetrate  new markets;  (iv) further
penetrating  the domestic and  international  markets by allowing  access to the
Company's  data  bases  and  libraries,  as  well as to  additional  value-added
content,  over the Internet and World Wide Web; and (v) entering into  strategic
alliances  and/or  co-licensing  agreements  to build a Commercial  Library with
commercial/industrial  application  as  well  as  application  to the  Company's
existing military and aerospace business.

     The foregoing  statements  regarding the Company's  strategy and intentions
are  forward-looking  statements,  and  actual  results  may vary  substantially
depending upon a variety of factors, including,  without limitation,  changes in
and development of the Company's  market,  products and  technologies  and those
factors discussed under "Risk Factors" above.

     The Company generates revenues primarily through license agreements for its
data base  services  pursuant  to which it  receives  subscription  fees.  These
agreements  are generally for terms of 12 months,  but may be canceled by either
party upon 30 days' notice. The Company  anticipates that the dependence on such
subscriber revenues will continue for the foreseeable future.  Accordingly,  any
decline in the demand for or market  acceptance of the Company's  services would
have a material  adverse  effect on the  Company.  Sales to the  Company's  five
largest customers in fiscal 1995 and 1996 accounted for approximately 26 percent
and 21 percent,  respectively,  of the Company's  revenues.  The Company expects
that this  trend  will  continue  for the  foreseeable  future.  There can be no
assurance that the Company will sustain growth in revenues in the future.

Competition

     TACTech  competes with many data service  companies  which possess  greater
financial  and human  resources  than does  TACTech.  Many  information  service
provides  offer a  greater  variety  of  services  than  does  TACTech.  TACTech
believes,  however,  that it offers its  customers  a unique set of  information
services  that have been  specially  developed to assist the  military/aerospace
market in solving problems relating to the management of diminishing  sources of
supply and  technological  obsolescence,  as they  pertain  to high  reliability
semiconductor devices.

     TACTech  believes it is the only  on-line data  service  company  which has
focused all its resources on providing such highly  specialized  services,  thus
giving it an advantage in competing  favorably  with other  information  service
organizations who provide data services designed for more general application.

Marketing, Sales and Licensing

     TACTech  maintains  marketing,   customer  service  and  customer  training
representatives  in its Yorba  Linda,  California  headquarters  and a marketing
representative located in Orlando, Florida and New Orleans,  Louisiana.  TACTech
markets  its  data  services  through  highly  specialized  and  highly  trained
marketing  personnel who contact prospective  customers  directly.  TACTech also
promotes its services and identifies prospective customers through participation
in conferences and  conventions  dedicated  predominantly  or exclusively to the
issue of shrinking availability of military products due to a diminishing number
of  manufacturing   sources  for  military   specified   products,   or  due  to
technological obsolescence. Video sales aids and literature describing TACTech's
data services are also utilized in its marketing program.

     TACTech  licenses its proprietary  software and data services under written
license agreements with subscribers.  Although TACTech provides customer support
to its  subscribers to facilitate  efficient use of its data  services,  TACTech
does not warrant the data provided to its subscribers.

     Many  of  the  Company's   customers  access  the  Company  services  by  a
modem-to-modem  connection using the customers' personal computers. A portion of
the  Company's  strategy is to emphasize  delivery of its  services  through the
Internet and the World Wide Web rather than modem-to-modem distribution.


                                       28

<PAGE>

     Subscribers for the Company's  services can access the TACTech home page at
"www.tactech.com";   and  the  Company  is  seeking  ways  to  realize   greater
efficiencies for delivering its services through the Internet and the World Wide
Web by  augmenting  and  simplifying  the  use of its  existing  graphical  user
interface accessible on the Internet and World Wide Web.

   
     A  significant  portion of the  Company's  revenues  historically  has been
derived  from  large  sales to a limited  number of  customers  including  Arrow
Electronics and Lockheed Martin Marietta (at several locations). Pursuant to its
agreement  with Arrow  Electronics,  Arrow  Electronics  is the sole  electronic
component distributor that is permitted to use the Company's services.  Although
the loss of either or both of such customers may materially and adversely affect
the Company, in the case of Arrow Electronics, the Company's management believes
that if the Company were to lose Arrow  Electronics  as a customer,  the Company
would be able to replace the business lost from Arrow  Electronics with business
from other electronic component distributors.  In the fiscal year ended June 30,
1996, Arrow accounted for 12.6% of the Company's revenues, and Lockheed 5.4%. In
the nine months  ended March 31,  1997,  Arrow  constituted  9% and Lockheed 6%,
respectively, of the Company's revenues.
    

Customer Support and Warranty

     TACTech's  license  agreements  with  its  customers  include  in the  base
subscription  price  free  on-site  training  for  two  representatives  of  the
customer.  The  training  program  runs  for two days and  covers  three  areas:
operational and conceptual  understanding of the software  program's  capability
and application training for integrating TACTech's service into the subscriber's
system. Once on line, a subscriber may call TACTech for technical assistance, at
the subscriber's  cost, or use e-mail to obtain  assistance.  TACTech's  license
agreements expressly disclaim any warranty, express or implied, for the accuracy
of its data bases.

Security Measures

     TACTech  has  adopted a number of  security  measures  and  techniques.  To
protect  against a natural  disaster,  the Company  engages in daily system data
backups  and weekly  full system data  backups,  independent  library  tapes are
maintained  and off-site data storage is utilized  which  contains a full system
data  backup of library  information  and  private  customer  files.  To protect
against  unauthorized  usage, the Company  maintains a dual access code security
system.  The Company  controls  system  access and allows its clients to apply a
second level of security  codes that protect  their private  files.  All data is
maintained in an encrypted  state,  only the password  protected  security codes
controlled  by the Company  and the  Company's  customer  can open the files and
permit system usage. All entries to utilize the Company's  services are recorded
on a hard copy trail and are reviewed daily for proper authorization  clearance.
Safeguards are  programmed  into the entry codes that shut down the system after
five attempts are made to enter the system with faulty access codes. The Company
believes that these safeguards are sufficient to prevent the unauthorized use of
its data base services by subscribers and to frustrate penetration of its system
and  theft of its data  bases  and  programs  by  outsiders.  TACTech  meets the
Pentagon's  Orange Book  standards for security in its  industry.  TACTech is in
compliance with a G-2 level which is the highest security level for a networking
service.

Sources of Data Bases

     Information  for  TACTech's  data bases and  libraries is acquired from the
private and governmental sectors, including semiconductor manufacturers, defense
contractors  and  the  unclassified  records  of the  U.S.  Government  and  its
agencies.  Approximately  two-thirds of TACTech's information for its data bases
comes from numerous  companies in the private  sector which  generally make such
information  available to persons having a recognized need for such information.
The remaining  information  is obtained from  governmental  sources which can be
accessed pursuant to the Freedom of Information Act.

Research and Development

   
     TACTech's research and development  efforts principally focus on augmenting
TACTech's  existing customer interface design (the GUI on the Internet and World
Wide Web), new information  products,  system security,  and the programming and
maintaining  of TACTech's  hardware and software.  In the fiscal year ended June
30, 1996,  the Company spent $106,000 in research and  development,  compared to
$57,000 in the prior year.  For the nine months ended March 31,  1997,  research
and  development  expenses  equaled  $39,000,  compared  to  $41,000 in the 1996
period.

Directors  shall be  classified  into three  classes with the  directors in each

of the Board at not less than three nor more than ten  directors  with the exact
number being set by resolution of the Board of Directors.  The Company currently

     Zing approximately $75,000 in management fees.

     Grant of Options
     ----------------

     As of the date of this prospectus,  although 60,000 shares of Company Stock
have been  reserved  for  issuance  pursuant to the Option  Plan,  there were no
outstanding options to purchase or securities  convertible into Company Stock or
stock appreciation rights related to Company Stock.

     Compensation of Directors
     -------------------------

     TACTech does not pay  directors for their  services as  directors.  TACTech
may, in the future,  pay  directors  who are not officers or employees for their
services as directors plus a fee for committee meetings attended.

Employment Contracts, Termination of Employment
and Change-in-Control Arrangements

     Mr. Robert E. Schrader has an employment  agreement with TACTech,  the term
of  which  expires  on the  third  anniversary  of the  Distribution  Date.  Mr.
Schrader's agreement entitles him to a salary of $80,000 per annum. Mr. Schrader
has  no  contractual  entitlement  to any  bonus.  Pursuant  to  the  employment
agreement,  Mr.  Schrader  has  agreed  to serve as  TACTech's  Chief  Executive
Officer,  President and Chairman of the Board of Directors on a part-time basis.
In the event that a Change in Control (as defined in the  employment  agreement)
of TACTech occurs, Mr. Schrader may terminate his employment. In such event, Mr.
Schrader is required to extend the  duration of the  non-competition  agreements
set forth in the employment agreement to the third anniversary of such Change of
Control. In consideration for the extension of his agreement not to compete with
TACTech  after such Change of Control which  results in the  termination  of the
term of his  employment  agreement,  Mr.  Schrader will be entitled to receive a
lump sum payment  equal to the amount of the  remaining  base salary he would be
entitled to under his employment  agreement had it not been so terminated,  plus
$250,000.  Pursuant to such employment agreement,  Mr. Schrader is required only
to provide  part time  services  to the  Company,  but not less than 10 business
hours per week.

   
     Mr. Malcolm A. Baca has an employment agreement with TACTech under which he
will devote full-time  efforts on behalf of the Company.  The term of Mr. Baca's
employment  expires April 30, 1999. Mr. Baca's agreement  entitles him to a base
salary of $120,000 per annum,  plus five  percent  (5%) of  TACTech's  collected
revenues, except that on revenues attributable to another commissioned member of
TACTech's  management,  Mr.  Baca's  commission  is two and one half  percent (2
- -1/2%). In all events, Mr. Baca's compensation cannot exceed $350,000 subject to
increase based upon the National  Consumer Price Index.  All  commissions to Mr.
Baca are subject to his required  contribution of one-half of one percent (1/2%)
of  TACTech's  collected  revenues  to a bonus  pool  fund  for the  benefit  of
non-commissioned  members  of  management,  which  contribution  is  matched  by
TACTech.  In the event Mr. Baca is  terminated  without  good cause,  TACTech is
obligated to continue to pay  compensation  to Mr. Baca through  April 30, 1999.
Mr. Baca's  agreement  also prohibits Mr. Baca from selling any of his shares of
Common Stock during the one year period after the  Distribution  Date. After the
expiration of such one year period,  Mr. Baca is not permitted to sell in excess
of 25% of his shares of Company  Stock until the  expiration  of two years after
the Distribution Date.
    

     The Company has engaged Mr. Martin S. Fawer on a part-time basis to perform
supervisory financial and strategic analysis services. See "Certain Transactions
- -- Management Services."

Interest in Certain Transactions of Directors, Officers
and Principal Holders of Voting Securities

   

     As of June 18, 1997,  Mr.  Schrader  owned  1,152,711  shares of Zing Stock
constituting  approximately  46.3% of the issued and outstanding  shares of Zing
Stock;  and Mr.  Martin  Fawer owns 50,857  shares of Zing  Stock,  constituting
approximately  2% of the  issued  and  outstanding  shares  of Zing  Stock.  Mr.
Schrader,  Deborah J. Schrader (Mr. Schrader's wife) and Mr. Fawer are directors
of the Company and thus have an indirect interest in the various  agreements and
arrangements  between Zing and the Company  including the Zing Guaranteed Credit
Facility,  Indemnification  Agreement and the management services to be provided
to the Company by certain employees of Zing. See "Certain Transactions."
    


                                       33

     Zing has informed  the Company that it will agree to guaranty  repayment by
the Company of its obligations  under a credit facility to be provided by one or
more financial  institutions up to an aggregate  principal amount of $1,500,000,
plus interest accrued thereon.  Pursuant to the Indemnification  Agreement,  the
Company  and Zing have  entered  into  certain  agreements  with  respect to the
indemnification  of certain  liabilities  arising  from the  operation  of their
respective businesses.
    

     TACTech will engage  certain  Zing  employees  who will provide  management
services  to  the  Company.  Management  of the  Company  anticipates  that  the
aggregate  cost of such  services  will not exceed  $100,000 per year.  The Zing
Guaranteed  Credit  Facility,   Indemnification  Agreement  and  the  management
services to be provided  to the  Company by certain  employees  of Zing are more
fully described below under "Certain Transactions."

     On December 17, 1996, Zing advanced  $100,000 to Mr. Baca for personal uses
unrelated to the Company or any Company Stock in exchange for Mr. Baca's secured
promissory  note. The promissory  note,  which bears interest at 8.25% per annum
and which  matures on June 29,  1997,  is secured by a first  priority  security
interest in all of Mr. Baca's shares of Company Stock.

     1997 Option Plan

     The Company's Board of Directors has adopted and the Company's stockholders
have approved the  Transition  Analysis  Component  Technology,  Inc. 1997 Stock
Option Plan (the  "Option  Plan").  The Board  believes  that the Option Plan is
desirable to attract and retain executives,  other key employees and consultants
of outstanding ability.  Under the Option Plan, options to purchase an aggregate
of not more than 60,000  shares of Company  Stock are  available for grants from
time to time to key employees of and consultants to the Company. No options have
been  granted  under the Option  Plan,  and there are no  current  plans for the
granting of options to specific employees or consultants.

     The Option Plan is  administered  by a committee  appointed by the Board of
Directors.  The  committee  may  exercise  all of the  powers  of the  Board  of
Directors in relation to the Option Plan.  The committee is generally  empowered
to interpret the Stock Option Plan, to prescribe rules and regulations  relating
thereto,  to determine  the terms of the option  agreements,  to  determine  the
employees or consultants to whom options are to be granted, and to determine the
number of shares subject to each option and the exercise price thereof.  Options
granted to  employees,  including  directors  and officers may be  designated as
incentive stock options  ("ISOs").  The per share exercise price of ISOs may not
be less than 100% of the fair market value on the date the option is granted (or
110% of the fair  market  value  on the date of grant of an ISO if the  optionee
owns more than 10% of the  outstanding  Company  Stock).  The per share exercise
price for  non-qualified  stock  options may not be less than 75% of fair market
value on the date the option is granted.

     An option  agreement may provide for the surrender of the right to purchase
shares  under the  option in return  for a payment  in cash or shares of Company
Stock or a combination of cash and shares of Company Stock equal in value to the
excess of the fair market value of the shares with respect to which the right to
purchase is  surrendered  over the option price  therefor.  Moreover,  an option
agreement may provide for the payment of the option price,  in whole or in part,
by the delivery of a number of shares of Company  Stock (plus cash if necessary)
having a fair market value equal to such option price.

     Each option and all rights  granted  thereunder  shall not be  transferable
other than by will or the laws of descent  and  distribution  or  pursuant  to a
qualified  domestic  relations  order as  defined  by the Code or Title I of the
Employee  Retirement  Income  Security  Act of 1974,  as  amended,  or the rules
thereunder,  and shall be exercisable during the optionee's lifetime only by the
optionee or the optionee's guardian or legal representative.

     In the event of certain basic structural or capital changes in the Company,
the  Committee,  acting in its sole  discretion,  may make such  adjustments  to
options then  outstanding  as the Committee  deems  appropriate  to reflect such
change,  or provide  that the number of shares of  Company  Stock  covered by an
option  theretofore  granted  shall  be  adjusted  so  that  such  option  shall
thereafter  cover  the  number  and of shares  of stock or other  securities  or
property to which the optionee would have been entitled pursuant to the terms of
the agreement  relating to such change if, immediately prior to such change, the
optionee had been the holder of record of the number of shares of Company  Stock
then covered by such option.


                                       34

<PAGE>

     Options  designated as ISOs are intended to have the attendant tax benefits
provided  under Sections 421 and 422 of the Code.  Accordingly,  the Option Plan
provides that the aggregate fair market value  (determined at the time an ISO is
granted) of the Company Stock subject to ISOs  exercisable for the first time by
an employee  during any  calendar  year (under all plans of the Company) may not
exceed $100,000.

     The Board may  modify,  suspend or  terminate  the Option  Plan;  provided,
however, that certain material  modifications  affecting the Option Plan must be
approved  by the  stockholders  and any  change  in the  Option  Plan  that  may
adversely affect an optionee's rights under an option  previously  granted under
the Option Plan requires the consent of the optionee.

                          DESCRIPTION OF CAPITAL STOCK

Authorized Capital Stock

     Under the  Company  Certificate  in effect on the date of this  prospectus,
TACTech's  authorized capital stock consists of 10,000,000  authorized shares of
capital stock of which  5,000,000  shares are designated as Common Stock,  $0.01
par value,  and 5,000,000  shares are designated as Preferred  Stock,  $0.01 par
value. Prior to or on the Distribution Date, there will be a recapitalization of
TACTech based upon a  36.436-for-one  stock split (the "Stock Split").  Prior to
the Stock Split and the adoption of the Company  Certificate,  15,200  shares of
Common Stock were issued and  outstanding  and no shares of Preferred Stock were
authorized.  At the  Distribution  Date, after giving effect to the Stock Split,
there  will be issued and  outstanding  553,830  shares of Company  Stock and no
shares of  Preferred  Stock  will be issued  and  outstanding.  The terms of the
Company Stock will continue unchanged after the Distribution.

The Company Stock

     The holders of Company Stock after the Distribution will be entitled to one
vote for each share on all  matters  to be voted  upon by TACTech  shareholders,
including the election of directors,  and, except as otherwise  required by law,
the  holders of such shares  will  possess  exclusively  all voting  power.  The
holders of the Company Stock will not have any cumulative voting rights, nor any
conversion,  redemption or preemptive  rights.  The holders of the Company Stock
will also be entitled to such  dividends as may be declared from time to time by
the TACTech Board of Directors  from funds legally  available  therefor and upon
the  dissolution,  liquidation  or winding up of TACTech,  whether  voluntary or
involuntary,  will be entitled to receive pro rata all assets of TACTech legally
available for distribution to such holders.

     The  Company  has never  declared  or paid a cash  dividend  on the Company
Stock. Management currently intends to retain earnings to finance the growth and
development  of the  Company's  business  and does not  anticipate  paying  cash
dividends in the foreseeable future. Any payment of cash dividends in the future
will  depend  upon  the  Company's  earnings,  capital  requirements,  financial
condition and other factors deemed relevant by the Board of Directors.

   
     After the Distribution,  the Company will be an independent,  publicly-held
company.  The number and  identity of  stockholders  of the Company  immediately
after the Distribution  cannot currently be determined with certainty because it
will  be  based  on the  number  and  identity  of  stockholders  of Zing on the
Distribution  Date.  However,  based on the  number of record  stockholders  and
outstanding  shares of Zing Stock as of the close of business on the Record Date
and the  distribution  ratio of one share of Company Stock for every five shares
of Zing Stock, the Company expects to have approximately 80 holders of record of
Company  Stock and  approximately  553,830  shares of Company  Stock  issued and
outstanding immediately after the Distribution.  In addition, as provided for in
the Option Plan,  it is  anticipated  that the total number of shares of Company
Stock with respect to which options may be granted and  restricted  stock may be
awarded  under the  Option  Plan  will not  exceed  60,000  shares,  subject  to
adjustment  (together with the exercise price of options and the purchase price,
if any, of restricted stock) to reflect any change in the Company's  outstanding
shares  of  Company   Stock  by  reason  of  stock   dividends,   stock  splits,
recapitalizations, mergers, consolidations or other similar events affecting the
number  or kind  of  outstanding  shares.  It is  believed  that  directors  and
executive  officers of the Company  will own,  in the  aggregate,  approximately
53.5%  of  the  outstanding  shares  of  Company  Stock  immediately  after  the
Distribution.  See "Directors and  Management of TACTech  Security  Ownership of
Management."

     Upon  completion  of the  Distribution,  the  Company  will have issued and
outstanding  an  aggregate  of  553,830  shares of Company  Stock.  Of the total
outstanding  shares of  Company  Stock,  the  498,447  shares of  Company  Stock
distributed in the Distribution to holders of the 2,492,233 shares of Zing Stock
outstanding on the Record Date will be freely tradeable  without  restriction or
further  registration  under the Securities Act, unless acquired by "affiliates"
of the  Company  as that term is defined  in Rule 144 under the  Securities  Act
(which  sales  will  be  subject  to  certain  volume   limitations   and  other
restrictions   described   below).   The  Company  Stock   distributed  to  Zing
stockholders  will be freely  transferable,  except for shares  received  by any
persons who may be deemed to be "affiliates" of the Company under the Securities
Act. Persons who may be deemed  affiliates of the Company after the Distribution
generally  include  individuals or entities that control,  are controlled by, or
are under common control with the Company and may include  certain  officers and
directors of the Company as well as principal 
    


                                       36

stockholders  of the Company.  Persons who are affiliates of the Company will be
permitted  to sell their shares of Company  Stock only  pursuant to an effective
registration  statement  under  the  Securities  Act or any  exemption  from the
registration  requirements of the Securities Act, such as the exemption provided
by Section 4(1) of the Securities Act or Rule 144  thereunder.  The Section 4(1)
exemption  allows  the sale of  unregistered  shares  by a person  who is not an
issuer,  an  underwriter  or a dealer.  Rule 144  provides  persons  who are not
issuers  with  objective   standards  for  selling  restricted   securities  and
securities held by affiliates without  registration.  The rule requires that (1)
current public  information be available  concerning the issuer,  (2) restricted
stock generally be held two years or more; (3) volume  limitations are placed on
sales during any  three-month  period;  and (4)  affiliates  comply with certain
manner of sale restrictions.  The amount of Company Stock which could be sold by
a person (or persons whose shares are aggregated)  under Rule 144 during a three
month  period  cannot  exceed the  greater  of (1) one  percent of the shares of
Company  Stock  outstanding  as shown by the most  recent  report  or  statement
published  by the  Company,  or (2) the average  weekly  trading  volume for the
shares for a four-week period prior to the date that notice of the sale is filed
with the Securities and Exchange Commission.

     In addition,  an aggregate of 55,383 shares held by Mr. Baca are subject to
further  restriction  on the future  sale of such  shares  pursuant to a lock-up
arrangement set forth in his employment agreement.

     After Distribution, the Company may file a registration statement under the
Securities  Act to register  shares of Company  Stock  issuable upon exercise of
stock options  reserved for issuance under the Option Plan,  thus permitting the
resale  of  such  shares  in  the  public  market,  subject  to  certain  volume
limitations  applicable to affiliates,  without restriction under the Securities
Act. See "Directors and Management of TACTech - 1997 Option Plan."

     The Company is unable to estimate  the number of shares that may be sold in
the future by its existing  stockholders  or the effect,  if any,  that sales of
shares by such  stockholders  will have on the market price of the Company Stock
prevailing from time to time. Sales of a substantial  amount of Company Stock by
existing stockholders under Rule 144 or otherwise, or even the potential of such
sales,  may have an adverse effect on the market price of the Company Stock. See
"Risk Factors Shares Eligible for Future Sale."

     Authorized  but  unissued  and  unreserved  shares  of  Company  Stock  and
Preferred Stock may be utilized for a variety of corporate  purposes,  including
future public offerings to raise additional  capital or to facilitate  corporate
acquisitions.  The  existence  of  unissued  and  unreserved  Company  Stock and
Preferred  Stock may enable the Board of  Directors  to issue  shares to persons
friendly to current management or to issue Preferred Stock with terms that could
render more  difficult or discourage an attempt to obtain control of the Company
by  means of a  merger,  tender  offer,  proxy  contest  or  otherwise,  thereby
protecting  the  continuity  of the Company's  management.  The Company does not
currently have any plans to issue additional shares of Company Stock or to issue
Preferred  Stock  other  than  shares  of  Company  Stock  that may be issued in
connection   with  the  Option  Plan.  See  "Comparison  of  Rights  of  Company
Stockholders and Zing Stockholders -- Preferred Stock."

     The transfer  agent and  registrar for the Company Stock is The Bank of New
York,  Corporate Trust Department,  101 Barclay Street, 12th Floor, New York, NY
10286.

Comparison of Rights of Company Stockholders and Zing Stockholders

     Following the  Distribution,  holders of Zing Stock will become  holders of
Company  Stock and the rights of such  holders in respect of the  Company  Stock
will be governed by the Company  Certificate,  the Company By-laws and the DGCL.
Certain  differences  arise from this  change in  governing  law as well as from
distinctions  between the Company  Certificate  and Zing's  Amended and Restated
Certificate of Incorporation (the "Zing Certificate").  The material differences
and some of the important similarities of the rights of holders of Company Stock
and the holders of Zing Stock are described below.  This summary is qualified in
its entirety by reference to the full text of such  documents.  See  "Additional
Information" in order to obtain copies of such documents.

     Antitakeover  Provisions of the Company  Certificate  and Company  By-laws.
Zing and Mr. Malcolm Baca, as sole current  stockholders of the Company prior to
the  Distribution,  have approved the Company  Certificate and Company  By-laws.
Such Company  Certificate and Company By-laws (i) provide for a classified Board
of Directors from which directors may only


                                       37

<PAGE>

be removed by  stockholders  for cause by (a) not less than 66-2/3% of the total
voting power of all  outstanding  shares of stock  entitled to vote generally in
the  election  of  directors  or (b)  action  by the  Board of  Directors;  (ii)
generally  provide that only a majority of the Board of Directors of the Company
shall have the  authority  to fill  vacancies on the Board of  Directors;  (iii)
restrict the right to amend certain  provisions of the Company  Certificate  and
Company  By-laws;  (iv)  restrict  the  right of  stockholders  to call  special
meetings;  and (v) authorize the Company's Board of Directors to issue Preferred
Stock without further  stockholder  approval.  These  provisions are designed to
encourage  any person who desires to take control of and/or  acquire the Company
to enter into negotiations  with the Board of Directors of the Company,  thereby
making more difficult the acquisition of the Company by means of a tender offer,
a proxy contest or other  non-negotiated  means.  In addition to encouraging any
person  intending  to attempt a takeover  of the Company to  negotiate  with the
Board of Directors of the Company,  these  provisions also curtail such person's
use of a dominant equity interest to control any negotiations  with the Board of
Directors of the Company.  Under such  circumstances,  the Board of Directors of
the Company may be better able to make and implement reasoned business decisions
and protect the interests of all of the Company's stockholders. Any one of, or a
combination  of, the above  anti-takeover  provisions  could  discourage a third
party from attempting to acquire  control of the Company.  A copy of the Company
Certificate and Company By-laws are each filed as an exhibit to the registration
statement of which this prospectus is a part.

     The provisions of the Company's Certificate, By-laws and the DGCL which may
have an anti-takeover effect, are as follows:

     Delaware  Takeover  Statute.  The Company is subject to the  provisions  of
Section 203 of the Delaware  General  Corporation  Law (the  "DGCL")  regulating
corporate  takeovers.  Section 203 prevents certain Delaware  corporations  from
engaging,  under  certain  circumstances,  in a  "business  combination",  which
includes a merger or sale of more than 10% of the corporation's  assets with any
"interested  stockholder" (generally defined as a stockholder who, together with
its affiliates and associates, owns 15% or more of the corporation's outstanding
voting shares) for three years following the date that such  stockholder  became
an  "interested  stockholder"  unless  (i)  prior  to such  date,  the  board of
directors of the  corporation  approved  either the business  combination or the
transaction  which  resulted  in  the  stockholder   becoming  an  "  interested
stockholder",  (ii) upon  consummation of the transaction  which resulted in the
stockholder  becoming an "interested  stockholder,"  the interested  stockholder
owned at least 85% of the voting  stock of the  corporation  outstanding  at the
time  the  transaction  commenced  (excluding  certain  shares),  or (iii) on or
subsequent to such date,  the business  combination  is approved by the board of
directors of the  corporation  and authorized at an annual or special meeting of
stockholders  by the  affirmative  vote of at least 66-2/3 % of the voting stock
which is not owned by the  "interested  stockholder" or (iv) under certain other
circumstances. A Delaware corporation may "opt out" of the provisions of Section
203 with an express provision in its original certificate of incorporation or an
express  provision in its certificate of incorporation or by-laws resulting from
a  shareholders'  amendment  approved by at least a majority of the  outstanding
voting shares,  which  amendment  generally will not become  effective  until 12
months after the date of such amendment.  The Company has not "opted out" of the
provisions of Section 203.

     New  York  Takeover  Statute.  The  provisions  of the  New  York  Business
Corporation  Law ("BCL")  Section 912 are similar to the foregoing,  except that
(i) an  "interested  shareholder"  under New York Law is the direct or  indirect
beneficial  owner of at least 20% (not 15%) of the  corporation's  voting stock,
and  (ii)  the  corporation  may  not  engage  in a  business  combination  (the
definition  of which is  similar  to that under the  Delaware  statute)  with an
"interested  shareholder" for a period of five (rather than three) years, unless
one of the following  conditions is satisfied:  (a) the business combination had
been  approved by the board of directors  consisting  of the directors in office
prior to the date on which such  shareholder  became an interested  shareholder,
(b) the business  combination  is approved by a majority of  shareholders  other
than the  interested  shareholder no earlier than five years after the date such
shareholder  became an  interested  shareholder,  or (c) the  price  paid to all
shareholders meets certain conditions relating to the type and minimum amount of
consideration to be paid to shareholders other than the interested  shareholder.
A New York  corporation  may "opt out" of the  provisions of Section 912 with an
express  provision in its original  certificate of  incorporation  or an express
provision  in its  certificate  of  incorporation  or by-laws  resulting  from a
shareholders'  amendment  approved  by at least a  majority  of the  outstanding
voting shares (other than interested  stockholders),  which amendment  generally
will not become effective until 18 months after the date of such amendment.  The
Zing By-laws do not opt-out of Section 912.


                                       38

     Stockholder Approval of Certain Business Combinations. Generally, under the
DGCL, the approval by the  affirmative  vote of the holders of a majority of the
outstanding stock of a corporation entitled to vote on the matter is required to
consummate  a merger  or  consolidation  or sale,  lease or  exchange  of all or
substantially all of the corporation's assets.

     In addition to the  requirements  imposed by the DGCL discussed  above, the
Company Certificate requires,  under certain circumstances,  the approval by the
affirmative  vote of the holders of 66-2/3% of the  outstanding  voting power of
the  corporation  in  connection  with a  business  combination  with any  other
corporation,  if  such  corporation  is  the  beneficial  owner  of  10%  of the
outstanding   voting   power  of  the   Corporation   (defined   as  a  "Related
Corporation").  Such approval is not required if the business combination is (i)
approved by a majority of the directors who were members of the Company's  Board
of Directors  at the initial  filing of the Company  Certificate  or were acting
members of the Board prior to the acquisition of 10% beneficial ownership of the
outstanding voting power of the corporation by such Related  Corporation and its
affiliates or (ii) is an internal corporate transaction  involving  subsidiaries
of the Company.

     In  addition  to the  requirements  of the BCL  discussed  above,  the Zing
Certificate  requires,  under  certain  circumstances,  that prior to a business
combination  with any other  corporation,  if such corporation is the beneficial
owner of more than 10% of any class of equity  security  of Zing  (defined  as a
"Tender Offeror"),  a meeting of the shareholders of Zing be held to act thereon
and  the  approval  by the  affirmative  vote of the  holders  of 66-2/3% of the
outstanding  Stock  of Zing.  Such  approval  is not  required  if the  business
combination  (i) is  approved  by a majority  of the  directors  who were acting
members  of the Board  prior to the  acquisition  by the  Tender  Offeror of 10%
beneficial  ownership  of any  class of  equity  security  of Zing or (ii) is an
internal corporate transaction involving subsidiaries of Zing.

     Number and  Election of  Directors.  The DGCL  permits the  certificate  of
incorporation  or the by-laws of a corporation to contain  provisions  governing
the number and terms of directors.  However, if the certificate of incorporation
contains  provisions  fixing the  number of  directors,  such  number may not be
changed  without  amending the  certificate of  incorporation.  Both the Company
Certificate and the Zing Certificate  provide that the number of directors shall
be fixed from time to time pursuant to a resolution adopted by a majority of the
entire Board of Directors.

     The Company  Certificate and the Company By-laws provide that the number of
directors  shall be fixed at not less than three nor more than ten, from time to
time,  pursuant  to  resolution  adopted  by a majority  of the total  number of
authorized  directors  (whether or not there exist any  vacancies in  previously
authorized  directorships  at the time any such  resolution  is presented to the
Board for adoption). In addition, the Company By-laws provide that at such times
or any times that all shares of stock of the corporation are owned  beneficially
and of record by less than three stockholders, the Board of Directors by vote of
a majority of the Board of Directors or a majority of the  stockholders  may fix
the  number  of  directors  at less than  three but not less than the  number of
stockholders.

     The Zing  Certificate  and the Zing  By-laws  provide  that the  number  of
directors  shall be fixed at not less than six nor more  than ten,  from time to
time,  pursuant  to  resolution  adopted  by a majority  of the total  number of
authorized  directors  (whether or not there exist any  vacancies in  previously
authorized  directorships  at the time any such  resolution  is presented to the
Board for adoption). In addition, the Zing By-laws provide that at such times or
any times that all shares of stock of the corporation are owned beneficially and
of record by less than three  stockholders,  the Board of Directors by vote of a
majority of the Board of Directors or a majority of the stockholders may fix the
number  of  directors  at less  than  three  but not  less  than the  number  of
stockholders.

     The DGCL permits the certificate of  incorporation  of a corporation or its
by-laws to provide that directors be divided into one, two or three classes. The
term of office of one class of  directors  shall expire each year with the terms
of office of no two classes expiring the same year. The Company  Certificate and
the Company  By-laws provide that if there are more than three (3) but less than
seven (7)  directors,  the Board of Directors be divided into two classes,  with
the first  term of office to expire at the next  annual  meeting  and the second
term of office to expire at the second succeeding annual meeting.  Additionally,
to the  extent  there are more than six (6)  directors,  the Board of  Directors
shall be  divided  into  three  classes at the  annual  meeting  following  such
increase in the number of directors,  with the term of the first class to expire
at the first succeeding  annual meeting,  the term of the second class to expire
at the  second  succeeding  annual  meeting  and the term of the third  class to
expire at the third succeeding annual meeting. Additionally, the Company By-laws
provide that at each annual


                                       39

<PAGE>

meeting  following  a meeting  at which the Board is  initially  classified  and
elected in three classes,  directors  elected to succeed those  directors  whose
terms expire shall be elected for a term expiring at the third succeeding annual
meeting of shareholders after their election.

         The Zing  Certificate  and the Zing  By-laws  provide that if there are
more than six (6) but less than nine (9)  directors,  the Board of  Directors be
divided  into two  classes,  with the first term of office to expire at the next
annual meeting and the second term of office to expire at the second  succeeding
annual  meeting.  Additionally,  to the  extent  there  are more  than  nine (9)
directors,  the Board of Directors  shall be divided  into three  classes at the
annual meeting following such increase in the number of directors, with the term
of the first class to expire at the first succeeding annual meeting, the term of
the second class to expire at the second  succeeding annual meeting and the term
of  the  third  class  to  expire  at  the  third  succeeding   annual  meeting.
Additionally,  the Zing By-laws provide that at each annual meeting  following a
meeting at which the Board is initially classified and elected in three classes,
directors elected to succeed those directors whose terms expire shall be elected
for a term expiring at the third succeeding annual meeting of shareholders after
their election.

     Amendments to Charter.  Under the DGCL,  unless  otherwise  provided in the
certificate  of  incorporation,  a  proposed  amendment  to the  certificate  of
incorporation  requires an  affirmative  vote of a majority  of the  outstanding
stock entitled to vote thereon. If any such amendment would adversely affect the
rights of any  holders of shares of a class or series of stock,  the vote of the
holders of a majority of all outstanding  shares of the class or series,  voting
as a class, is also necessary to authorize such amendment.

     The  Company  Certificate   provides  that  no  amendment  to  the  Company
Certificate shall amend,  alter, change or repeal the provisions relating to the
(i)  classification  of the Board of  Directors;  (ii)  number  and  removal  of
directors;  (iii) term of office of directors;  (iv) filling of vacancies on the
Board of Directors,  unless the  amendment,  alteration,  change or repeal shall
have  received the  affirmative  vote of the holders of at least (a) 66-2/3 % of
the total voting power of all of the outstanding shares of voting stock entitled
to vote  thereon,  voting as a single class and (b) a majority of shares held by
other  than the  "interested  stockholders"  (generally  defined as a person who
beneficially  owns an aggregate of 15% or more of the voting power of all shares
entitled to vote for the election of directors.)

     The Zing  Certificate  provides  that no  amendment to the  certificate  of
incorporation  shall amend,  alter,  change or repeal the provisions relating to
the (i)  classification  of the Board of  Directors;  (ii) number and removal of
directors;  (iii) term of office of directors;  (iv) filling of vacancies on the
Board of Directors,  unless the  amendment,  alteration,  change or repeal shall
have  received the  affirmative  vote of the holders of at least (a) 66-2/3 % of
the total voting power of all of the outstanding shares of voting stock entitled
to vote thereon,  voting as a single class, and (b) a majority of shares held by
other  than the  "interested  stockholders"  (generally  defined as a person who
beneficially  owns an aggregate of 20% or more of the voting power of all shares
entitled to vote for the election of directors.)

     Amendments to By-laws. Under the DGCL, the power to adopt, alter and repeal
the  by-laws  is  vested in the  stockholders,  except  to the  extent  that the
certificate  of  incorporation  vests it in the board of directors.  The Company
By-laws provide that the by-laws of the corporation,  or any one of them, may be
supplemented,  amended or repealed by the affirmative  vote of a majority of the
Board of  Directors  and as  permitted  by law, or by the vote of 66-2/3% of the
holders of outstanding  stock entitled to vote thereon at any meeting at which a
quorum is present;  provided,  however, that the affirmative vote of the holders
of at least 66-2/3% of the voting  power of the then  outstanding  shares of the
voting stock of the corporation,  voting together as a single class, is required
to amend, alter or repeal the sections of the by-laws which have the same effect
as those provisions of the Company Certificate,  governing (i) classification of
the Board of Directors of the corporation;  (ii) number of directors; (iii) term
of office of  directors;  (iv) removal of directors and (v) filling of vacancies
on the  Board  of  Directors.  The Zing  By-laws  contain  identical  provisions
governing amendments to the By-laws.

     Special Stockholder  Meetings.  The DGCL provides that a special meeting of
stockholders  may be  called  by the  board of  directors  or by such  person or
persons as may be  authorized  by the  certificate  of  incorporation  or by the
by-laws.  The Company By-laws provide that special meetings may be called by the
President or the Board of Directors; and shall be called by the President or the
Secretary  at the request in writing of a majority of the Board of  Directors or
of the holders of 66-2/3%


                                       40

<PAGE>

of the entire capital stock of the Company issued and  outstanding  and entitled
to vote.  The Zing By-laws  contain  identical  provisions  for calling  special
stockholder meetings.

     The Company Certificate  provides that except as otherwise required by law,
special  meetings  of  stockholders  of the  Company  may be called  only by the
Chairman of the Board,  the Vice Chairman of the Board, if any, the President or
the Board of Directors; and shall be called by the President or the Secretary at
the request in writing of a majority of the Board of Directors or of the holders
of 66-2/3% of the entire capital stock of the Company issued and outstanding and
entitled to vote. The Zing  Certificate does not contain a provision for calling
special meetings of stockholders.

     Stockholder  Consent in Lieu of Meeting.  Under the DGCL,  unless otherwise
provided in the certificate of  incorporation,  any action required or permitted
to be taken at a meeting of stockholders may be taken without a meeting, without
prior notice and without a vote, if a written consent or consents  setting forth
the action taken is signed by the holders of  outstanding  stock having not less
than the minimum  number of votes that would be  necessary  to authorize or take
such  action at a meeting at which all shares  entitled to vote upon such action
were present and voted. The Company By-laws provide that any action which may be
taken at a meeting of stockholders  may be taken without a meeting if there is a
written  consent of  stockholders  who would have been entitled vote to cast the
minimum  number of votes that would be necessary  to  authorize  the action at a
meeting at which all of the stockholders were present and voting.

     The Zing By-laws provide that any action which may be taken at a meeting of
stockholders  may be taken  without  a  meeting  if there is  unanimous  written
consent of the stockholders who would have been entitled vote upon the action if
such meeting were held.

     Quorum of Stockholders.  Under the DGCL, a quorum consists of a majority of
the shares entitled to vote,  present in person or represented by proxy,  unless
otherwise provided in the certificate of incorporation or the by-laws, but in no
event can the quorum be less than one-third of the  outstanding  shares entitled
to vote.

     Both the Company  By-laws  and the Zing  By-laws,  provide  that the quorum
required in connection  with all  elections  and  questions put to  stockholders
shall be one-third of the outstanding shares entitled to vote.

     Preferred  Stock.  The  Company  Certificate  provides  that  the  Board of
Directors  of  the  Company,   without  further  approval  or  action  from  the
stockholders, is authorized, subject to the limitations imposed by law, to issue
shares  of  Preferred  Stock  in one or more  series,  and to fix as to any such
series,  the dividend  rate,  redemption  prices,  preferences on liquidation or
dissolution,  sinking fund terms, if any, conversion rights,  voting rights, and
any other  preference or special rights or  qualifications.  The issuance of the
Preferred  Stock could have the effect of delaying , deferring  or  preventing a
change in control of the Company without further action by the stockholders. The
Company has no present  plans to issue any shares of Preferred  Stock.  The Zing
Certificate  does not contain a provision  for the issuance of Preferred  Stock.
See "Description of Capital Stock - The Company Stock."

     In addition to the  Antitakeover  provisions  discussed  above, the Company
Certificate, the Company By-laws and the DGCL provide for the following:

     Redemption  of  Capital   Stock.   Under  the  DGCL,   subject  to  certain
limitations,  a  corporation's  stock may be made subject to  redemption  by the
corporation  at its  option,  at the option of the holders of such stock or upon
the  happening  of a  specified  event.  The  DGCL  prohibits  the  purchase  or
redemption  of stock  when  the  capital  of a  corporation  is or would  become
impaired;  but shares  entitled  to dividend or  liquidation  preference  may be
purchased  or redeemed  out of capital if such shares are retired and capital is
reduced in accordance with legal  requirements.  Neither the Company Certificate
(but without reference to the Preferred Stock) nor the Zing Certificate contains
provisions governing the redemption of capital stock.

     Limitation  on  Directors'  Liability;   Indemnification  of  Officers  and
Directors.  Section  102 of the DGCL  allows a  corporation  to  include  in its
certificate of  incorporation a provision that limits or eliminates the personal
liability of  directors of the  corporation  and its  shareholders  for monetary
damages for breach of fiduciary duty as a director. Section 102 of the DGCL does
not, however,  permit a corporation to limit or eliminate the personal liability
of a director for (1) any breach of

                                       41

<PAGE>

the director's duty of loyalty to the corporation or its stockholders,  (2) acts
or omissions  not in good faith or which  involve  intentional  misconduct  or a
knowing  violation of law,  (3)  intentional  or  negligent  payment of unlawful
dividends or unlawful stock purchases or redemptions or (4) any transaction from
which the director derived an improper personal benefit. The Company Certificate
provides for  limitations on directors'  and officers'  liability to the fullest
extent permitted by the DGCL.

     Section 145 of the DGCL provides  that a  corporation  may indemnify any of
its officers and directors party to any action,  suit or proceeding by reason of
the  fact  that he is or was a  director,  officer,  employee  or  agent  of the
corporation  or is or  was  serving  at the  request  of  the  corporation  as a
director,  officer,  employee or agent of another  organization  by, among other
things,  a majority vote of directors  (even though less than a quorum) who were
not parties to such action,  suit or  proceeding,  provided that such officer or
director acted in good faith and in a manner he reasonably  believed to be in or
not  opposed to the best  interests  of the  corporation.  The  Company  By-laws
provide for  indemnification  of officers  and  directors  of the Company to the
maximum  extent and in the manner  permitted  by the DGCL.  The BCL provides for
indemnification  of officers and directors of a corporation and the Zing By-laws
contain provisions for  indemnification of officers and directors to the fullest
extent permitted under the BCL.

     Similarly,  Section 402 of the BCL allows a  corporation  to include in its
certificate  of  incorporation  a  provision  that  limits or  eliminates  their
personal  liability of  directors to the  corporation  or its  stockholders  for
monetary damages for breach of fiduciary duty as a director,  provided that such
corporation  cannot  eliminate or limit the liability of a director for any acts
or omissions prior to adoption of the Zing Certificate or if a judgment or other
final  adjudication  adverse to him  establishes  that (i) his acts or omissions
were in bad faith or involved  intentional  misconduct or a knowing violation of
law; (ii) he personally  gained in fact a financial profit or other advantage to
which he was not legally  entitled;  or (iii) he voted for or  concurred  in the
declaration of a dividend or other  distribution or repurchase or stock contrary
to the BCL, the distribution of assets to stockholders after dissolution without
paying or adequately  providing for all known  liabilities  or the making of any
loan to a director contrary to the BCL. The Zing Certificate contains provisions
for  indemnification  of officers and directors to the fullest extent  permitted
under the BCL.

     Dissenter's  Rights.  The DGCL  provides  that  stockholders  of a Delaware
business  corporation  are entitled to appraisal  rights only in connection with
statutory  mergers or  consolidations  in which their  corporation is one of the
corporations which is merging or consolidating ("constituent corporation").  The
DGCL  further  provides  that no  appraisal  rights  will be  available,  unless
otherwise set forth in the certificate of incorporation (the Company Certificate
does not so  provide),  to the  holders of shares of a  constituent  corporation
which has a class or series of stock either (i) listed on a national  securities
exchange  or (ii) held of record by more than  2,000  stockholders  unless  such
stockholders   are   required  by  the  terms  of  the  merger  to  receive  any
consideration other than shares of stock of the surviving corporation, shares of
stock of  another  corporation  which are so  listed  or held by such  number of
record  holders,  cash  in lieu  of  fractional  shares  of  such  stock  or any
combination thereof. Appraisal rights also are unavailable under Delaware law to
stockholders of a constituent  corporation  surviving a merger if no vote of the
stockholders of the surviving corporation is required to approve the merger.

     The BCL grants dissenters' rights to stockholders  (i.e., the right to cash
payment of the fair value of one's  shares  determined  by  judicial  appraisal)
generally  (i) in the case of a merger or  consolidation,  (ii) a sale of all or
substantially  all of the  corporation's  assets,  (iii)  and (in the  case of a
shareholder whose shares are adversely  affected thereby) certain  amendments to
the certificate of  incorporation.  The Zing Certificate  provides for appraisal
rights to the full extent under the BCL.

                              CERTAIN TRANSACTIONS

     On or prior to the Distribution  Date, the Company and Zing will enter into
certain   agreements,   described   below,   which  will  govern  their  ongoing
relationships. These agreements were structured and negotiated while the Company
was  owned  by  Zing  and   consequently  are  not  the  result  of  arms-length
negotiations  between  independent  parties.  Nonetheless,  the Company and Zing
believe  that the terms are fair to the  parties  and  contain  terms  which are
generally comparable to those which would result from arms-length  negotiations.
In each case,  the terms of these  agreements  have been reviewed by individuals
who will be included at a senior management level within the Company.


                                       42

<PAGE>

     The agreements  summarized  below are filed as exhibits to the registration
statement of which this prospectus is a part. The following  descriptions do not
purport to be complete and are  qualified in their  entirety by reference to the
agreements as filed.

Zing Guaranteed Credit Facility

   
     Zing has informed the Company that, as an enhancement to enable the Company
to obtain credit facilities from one or more financial  institutions,  Zing will
guaranty the Company's obligations to one or more financial institutions under a
$1,500,000  credit facility.  Zing will agree to assist the Company to negotiate
and secure such a facility,  but will not  guaranty the  availability  of such a
facility.  A letter of intent with respect to a three-year  $1,500,000 revolving
credit facility with Fleet Bank has been negotiated by the Company.
    

Indemnification Agreement

     Simultaneously  with the  consummation  of the  Distribution,  Zing and the
Company  will  enter into an  Indemnification  Agreement  (the  "Indemnification
Agreement").   The  Indemnification  Agreement  will  obligate  the  Company  to
indemnify and save harmless Zing and its directors,  officers, employees, agents
and/or  affiliates  from  any and  all  costs,  expenses,  losses,  damages  and
liabilities  incurred or suffered,  directly or indirectly,  by the  indemnities
resulting  from or  attributable  to (i) the  operation  of the Company from and
after the  Distribution;  (ii) any claim, suit or other type of proceeding based
upon or arising out of or in connection  with the operation of the Company prior
to the Distribution,  other than the tax consequences of the  Distribution;  and
(iii) any claim, suit or other type of proceeding based upon,  arising out of or
in connection with any information  concerning the Company in this prospectus or
any information furnished by the Company concerning the Company for inclusion in
this prospectus.

     Zing will  indemnify  and save  harmless  the  Company  and its  directors,
officers,  employees,  agents  and/or  affiliates  from any claims  incurred  or
suffered,  directly or indirectly,  by them resulting from or  attributable  to,
among other things,  (i) the operation of Zing from and after the  Distribution;
(ii) any claim,  suit or other type of proceeding based upon,  arising out of or
in connection  with the operation of Zing's  business  (other than the Company's
business) prior to the Distribution;  and (iii) any claim, suit or other type of
proceeding  based upon,  arising out of or in  connection  with any  information
concerning  Zing  in  this  prospectus  or any  information  furnished  by  Zing
concerning Zing for inclusion in this prospectus.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be  permitted  to  directors,  officers or persons  controlling  the
registrant  pursuant  to the  foregoing  provisions,  the  registrant  has  been
informed  that in the opinion of the  Securities  and Exchange  Commission  such
indemnification  is against public policy as expressed in the Securities Act and
is, therefore, unenforceable.

Management Services

   
     The Company will engage three Zing employees on part-time basis, to provide
supervisory  financial and strategic  analysis  services and various  reporting,
accounting and  administrative  services to the Company.  The Zing employees are
expected to devote no more than between 20% to 50% of their respective  business
time to the affairs of the Company in connection with rendering of advice in the
development of the Company's business plan, advising the Company with respect to
and negotiating agreements on the Company's behalf,  coordinating communications
with  the  Company's  stockholders,  interfacing  with  the  Company's  counsel,
preparing  and  filing  the  Company's  tax  returns  and  reports  required  by
applicable  securities laws and rules of applicable stock  exchanges,  reviewing
and  supervising  the Company's  accounting  department and systems from time to
time and  suggesting  revisions  and  changes  thereto,  performing  supervisory
financial and strategic analysis services,  and performing such further services
as such employees may agree.  Management expects that aggregate costs to be paid
by the Company to Zing for the  services to be rendered by such persons will not
exceed $100,000 per year. Such services were previously  provided by Zing to the
Company and were included in general  corporate  charges.  As of March 31, 1997,
such charges  aggregated  $75,000.  As a result of the direct  engagement of the
Zing employees by the Company, Zing will have a concomitant reduction in payroll
expense.  The acquired  services are currently being provided by Martin S. Fawer
(the  Chief  Financial  Officer),   Don  Guarnieri   (Controller)  and  Michelle
Mastropolo (Office Administrator). The Company
    


                                       43

<PAGE>

expects that it will require management  services for approximately a three year
period, although there is no guarantee that the particular individuals currently
engaged will be performing such services at that time.

Tax Reimbursement

   

     Zing and the Company are parties to a tax  reimbursement  arrangement under
which income tax  liabilities  of Zing incurred  since the  commencement  of its
fiscal year beginning July 1, 1994 have been allocated to the Company  estimated
to reflect the operations of the Company on a standalone  basis. As of March 31,
1997,  approximately $158,000 of such tax liabilities have been allocated to the
Company.
    

                                  LEGAL MATTERS

counsel to the  Company and Zing with  regard to certain  matters,  and has been

          SECURITIES AND EXCHANGE COMMISSION POLICY ON INDEMNIFICATION
                         FOR SECURITIES ACT LIABILITIES

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors,  officers and controlling  persons of the Company
pursuant to the Company Certificate,  contractual agreements,  or otherwise, the
Company has been  advised  that in the opinion of the  Securities  and  Exchange
Commission  such  indemnification  is against  public policy as expressed in the
Securities Act and is, therefore, unenforceable.

                             REPORTS OF THE COMPANY

     As a result of the  Distribution,  the  Company  will be required to comply
with  the  reporting  requirements  of  the  Exchange  Act  and,  in  accordance
therewith,  to file  annual  quarterly  and other  periodical  reports  with the
Securities and Exchange Commission. Additionally, the Company will be subject to
the proxy and solicitation requirements of the Exchange Act. The Company intends
to furnish its stockholders  with annual reports  containing  audited  financial
statements and a report thereon of its independent auditors.  The Securities and
Exchange Commission maintains a Web site at "http:\\ www.sec. gov" that contains
reports,  proxy  and  information  statements  and other  information  regarding
issuers that file electronically with the Securities and Exchange Commission.

                         Report of Independent Auditors

To the Directors of
Transition Analysis Component Technology, Inc.

We have audited the accompanying balance sheets of Transition Analysis Component
Technology,  Inc.  ("TACTech")  as of June 30,  1996 and 1995,  and the  related
statements of income,  stockholders'  equity (deficiency) and cash flows for the
years then ended.  These  financial  statements  are the  responsibility  of the
Company's  management.  Our  responsibility  is to  express  an opinion on these
financial statements based on 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  significant  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 TACTech as of June 30, 1996 and
1995,  and the results of its  operations  and its cash flows for the years then
ended in conformity with generally accepted accounting principles.

                                  June 30, 1996

1. Organization and Summary of Significant Accounting Policies

Organization

Transition  Analysis  Component  Technology,  Inc.  ("TACTech")  is a 90%  owned
subsidiary  of Zing  Technologies,  Inc.  (Zing) and is located in Yorba  Linda,
California. The remaining 10% is owned by one officer.

General Business Description

TACTech   licenses   proprietary   computer   software   databases  to  military
manufacturers  and  defense  contractors  primarily  in the United  States.  The
databases  provide the users with  information in regards to  microcircuits  and
semiconductor  devices  used in the  manufacture  of systems  for  military  and
aerospace applications.

Revenue Recognition and Concentration of Credit Risk

The  Company  recognizes  revenue  on a monthly  basis  with  substantially  all
contracts cancelable on 30 days notice.

Equipment

Equipment is stated at cost and is depreciated  using the  straight-line  method
over five years.

Research and Development

TACTech's  research and  development  efforts  principally  focus on  augmenting
existing customer interface designs, new information products,  systems security
and the  programming  and  maintenance  of hardware and  software.  Research and
Development expenses amounted to $106,000 in 1996 and $57,000 in 1995.

Pro Forma Net Income Per Common Share

Pro Forma net income per common share is based on the weighted average number of
shares of Common  Stock  outstanding  adjusted  to give  effect to the  proposed
36.436-for-one stock split in connection with the proposed transaction described
in Note 6.

Use of Estimates

The preparation of 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.

                    Notes to Financial Statements (continued)

1. Organization and Summary of Significant Accounting Policies (continued)

Fair Value of Financial Information

The carrying amounts of cash, accounts receivable,  accounts payable and accrued
expenses  reasonably  approximate  fair value due to the short maturity of these
items.

Recent Accounting Pronouncement

In 1995, the Financial  Accounting Standards Board issued Statement of Financial
Accounting  Standards  No. 121,  "Accounting  for the  Impairment  of Long-Lived
Assets to Be Disposed  Of." The Company will adopt  Statement  No. 121 in fiscal
1997, and the impact, if any, is not expected to be material.

Agreements

In April 1993, TACTech entered into a three-year  exclusive  licensing agreement
with a distributor at an annual rate of $108,000 for use of TACTech's  database.
This agreement was amended in May 1993 with an expiration date of June 1998. The
annual rate was amended to $200,000  effective  July 1995.  TACTech  agreed that
during  the term of this  agreement  it would not grant or  authorize  any other
party access to its  databases or services if such party were in the business of
distributing  electronic  components  parts.  The  agreement  may be renewed for
successive one-year periods by mutual written consent of the parties.

2. Income Taxes

The Company  files its federal  income  taxes on a  consolidated  basis with its
parent,  Zing. Income taxes are computed on a separate company basis pursuant to
the liability  method.  Current taxes payable,  reported as accrued income taxes
due parent  company,  as of June 30,  1996 and 1995,  amounted  to  $66,415  and
$16,400, respectively.

The Company  records taxes under the liability  method of accounting  for income
taxes. Under this method, any deferred tax assets and liabilities are determined
based on  differences  between  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.

The difference between the effective tax rate and the Federal tax rate of 34% is
due to the effect of the graduated Federal tax rate schedule and state taxes.

                    Notes to Financial Statements (continued)

3. Employee Benefit Plans

The parent company has a deferred compensation program for all employees,  which
is  qualified  under  Section  401-K of the  Internal  Revenue  Code.  Under the
program,  contributions  to be made by the Company are at the  discretion of the
Board of Directors of the Company.  The Company  contributed  $2,800 in 1996 and
$1,500 in 1995. The Company does not maintain post retirement benefit plans.

4. Leases

TACTech  is  currently  renting  facilities  in  Yorba  Linda,  California  on a
month-to-month  basis.  Lease expense for the years ended June 30, 1996 and 1995
was $44,000 and $39,000, respectively.

5. Related Parties

The Company is allocated a portion of Zing's corporate  administrative  expenses
which amounted to $75,000 in 1996 and 1995 and are included in selling,  general
and administrative expenses.

The Executive  Vice  President and General  Manager has an employment  agreement
expiring  on May 1, 1999,  entitling  him to a salary  plus five  percent of the
Company's  collected revenues,  except that on revenues  attributable to another
commissioned member of management, the commission is two and one-half percent.

6. Subsequent Events (Unaudited)

Commencing  July  1,  1996,  the sum of  $80,000  per  year  will be paid to the
President of Zing for services to be provided as the Chief Executive  Officer of
TACTech on a part-time basis.

   
The  Company  filed a  registration  statement  on Form SB-1 for the  purpose of
distributing  the  Common  Stock  of the  Company  which is owned by Zing to the
shareholders  of Zing. In connection with the proposed  transaction,  the common
shares   authorized  and   outstanding   will  be  split  on  an   approximately
36.436-for-one basis and 553,830 shares will be issued and outstanding.

6. Subsequent Events (Unaudited)

Also, in connection with the proposed transaction,  the due to parent balance as
of the  effective  date of the  transaction  will be  converted  to equity  and,
accordingly, will be included in additional paid-in capital.

As of the  Distribution  Date,  Zing and the  Company  will enter  into  several
agreements  and take certain other actions for purposes of governing  certain of
the ongoing  relationships between the two companies following the Distribution,
including relative  indemnification  obligations,  and the engagement of certain
Zing  employees  by  the Company on a part-time  basis. In  addition,  Zing will
assist the  Company in  obtaining  a credit  facility  from a bank and provide a
guaranty of the indebtedness.  Pursuant to the  Indemnification  Agreement to be
entered into between Zing and the Company in connection  with the  Distribution,
the Company  will agree to indemnify  Zing against all expenses and  liabilities
resulting from (i) the operation of the Company from and after the distribution,
and (ii) Zing's operations of TACTech's business prior to the Distribution other
than those based upon the tax  consequences  of the  Distribution  and (iii) any
claim,  suit or  other  type of  proceeding  based  upon,  arising  out of or in
connection with any information  furnished by the Company concerning the Company
for inclusion in the  prospectus  relating to the  distributions;  and Zing will
indemnify and save harmless the Company and its directors,  officers, employees,
agents  and/or  affiliates  for any claims  incurred  or  suffered,  directly or
indirectly,  by them resulting from or  attributable  to, among other things (i)
the operation of Zing after the Distribution, (ii) any claim, suit or other type
of proceeding based upon,  arising out of or in connection with the operation of
Zing's business (other than the Company's  business) prior to the  Distribution,
and (iii) any claim, suit or other type of proceeding based upon, arising out of
or in connection with any  information  concerning Zing in the prospectus or any
information  furnished by Zing  concerning Zing for inclusion in the Prospectus.
Although  the  Company  is not  aware  of any  pending  or  threatened  material
liability for which the Company anticipates  becoming obligated to make payments
in connection with its obligations to indemnify Zing,  there can be no assurance
that   such   indemnification   obligations   could   not  arise  or  that  such
indemnification obligations would not be material to the Company.

Under the terms of the credit  facility  referred  to above,  the  Company  will
receive a $1,500,000 revolving line of credit to be used for working capital and
equipment  acquisitions.  The facility will be for a three year term and will be
guaranteed by Zing.  Interest on the borrowings  will be a variable rate tied to
the Bank's prime rate. All personal  property of the Company will  collateralize
the borrowings.  In addition to the formal agreements  mentioned above, Zing has
agreed to perform  the  following  duties  and  agreed to render  the  following
services: to advise in the development of the Company's business plan; to advise
the  Company  with  respect  to  and to  negotiate  material  agreements  on the
Company's behalf; to coordinate  communications with the Company's stockholders;
to  advise  the  Company  with  respect  to and to  negotiate  acquisitions  and
financing;  to assist in preparing and filing the Company's  reports required by
applicable  securities laws and rules of applicable stock  exchanges;  to review
and supervise the Company's  accounting  department and information systems from
time to time and suggest  revisions  and changes  thereto;  and to perform  such
further  services  as  mutually  agreed to. In regard to the  duties  enumerated
above, the Chief Financial Officer,  Controller and Office Administrator of Zing
will  spend a  portion  of their  time and be placed  on the  Company's  payroll
accordingly.

6. Subsequent Event (Continued)

The Company's Board of Directors has adopted and the Company's stockholders have
approved the Transition  Analysis Component  Technology,  Inc. 1997 Stock Option
Plan (the  "Plan").  Under the Plan,  options to purchase up to 60,000 shares of
Common Stock are  available  for grant from time to time to key employees of and
consultants to the Company. No options have been granted under the Option Plan.

In December  1996,  Zing  advanced  $100,000  to the  Company's  Executive  Vice
President and General Manager in exchange for his secured  promissory  note. The
promissory  note, which matures on June 29, 1997, is secured by a first priority
security  interest in all of his shares of Company  Stock,  $49,000 of this loan
was paid back in March 1997.

In  connection  with the  proposed  distribution,  the  Company  will  amend its
certificate of  incorporation  to increase its authorized  capital to 10,000,000
shares of capital  stock of which such shares will be  designated  as  5,000,000
shares of common stock, $.01 par value, and 5,000,000 shares of preferred stock,
$.01 par value.

                Notes to Unaudited Condensed Financial Statements

   

                                 March 31, 1997

    

1. Organization and Basis of Presentation

Organization

   

Transition  Analysis  Component  Technology,  Inc.  ("TACTech")  is a 90%  owned
subsidiary of Zing  Technologies,  Inc.  ("Zing") and is located in Yorba Linda,
California. The remaining 10% is owned by one officer.

    

Basis of Presentation

   

The accompanying  unaudited condensed financial statements have been prepared in
accordance with generally accepted  accounting  principles for interim financial
information.  Accordingly,  they  do not  include  all of  the  information  and
footnotes  required by generally  accepted  accounting  principles  for complete
financial statements. In the opinion of management,  all adjustments (consisting
of normal recurring accruals)  considered necessary for a fair presentation have
been included.  Operating results for the nine month period ended March 31, 1997
are not necessarily  indicative of the results that may be expected for the year
ending June 30, 1997.
    

Proforma Net Income Per Common Share

Proforma net income per common share is based upon the weighted  average  number
of shares of common  stock  outstanding  adjusted to give effect to the proposed
36.436-for-one stock split in connection with the proposed transaction described
in Note 3.

2. Related Party Transactions

   

The Company is allocated a portion of Zing's corporate  administrative  expenses
amounting to $75,000 and $42,750 for the nine month periods ended March 31, 1997
and  1996,   respectively,   which  are   included  in   selling,   general  and
administrative expenses.

In addition,  beginning  July 1, 1996, the Company began paying a fee to Zing in
the  amount of  $100,000  per year,  for three  years for  management  oversight
services.  Further,  $80,000 per year will be paid to the  President of Zing for
services to be provided as the Chief Executive Officer of TACTech on a part-time
basis.

3. Subsequent Event

The  Company  filed a  registration  statement  on Form SB-1 for the  purpose of
distributing  the  Common  Stock  of the  Company  which is owned by Zing to the
shareholders  of Zing. In connection with the proposed  transaction,  the common
shares   authorized  and   outstanding   will  be  split  on  an   approximately
36.436-for-one basis and 553,830 shares will be issued and outstanding.

3. Subsequent Event (Continued)


Also, in connection with the proposed transaction,  the due to parent balance as
of the  effective  date of the  transaction  will be  converted  to equity  and,
accordingly, will be included in additional paid-in capital.

As of the  Distribution  Date,  Zing and the  Company  will enter  into  several
agreements  and take certain other actions for purposes of governing  certain of
the ongoing  relationships between the two companies following the Distribution,
including relative  indemnification  obligations,  and the engagement of certain
Zing  employees  by the Company on a part-time  basis.  In  addition,  Zing will
assist the  Company in  obtaining  a credit  facility  from a bank and provide a
guaranty of the indebtedness.  Pursuant to the  Indemnification  Agreement to be
entered into between Zing and the Company in connection  with the  Distribution,
the Company  will agree to indemnify  Zing against all expenses and  liabilities
resulting from (i) the operation of the Company from and after the distribution,
and (ii) Zing's operations of TACTech's business prior to the Distribution other
than those based upon the tax  consequences  of the  Distribution  and (iii) any
claim,  suit or  other  type of  proceeding  based  upon,  arising  out of or in
connection with any information  furnished by the Company concerning the Company
for inclusion in the  prospectus  relating to the  distributions;  and Zing will
indemnify and save harmless the Company and its directors,  officers, employees,
agents  and/or  affiliates  for any claims  incurred  or  suffered,  directly or
indirectly,  by them resulting from or  attributable  to, among other things (i)
the operation of Zing after the Distribution, (ii) any claim, suit or other type
of proceeding based upon,  arising out of or in connection with the operation of
Zing's business (other than the Company's  business) prior to the  Distribution,
and (iii) any claim, suit or other type of proceeding based upon, arising out of
or in connection with any  information  concerning Zing in the prospectus or any
information  furnished by Zing  concerning Zing for inclusion in the Prospectus.
Although  the  Company  is not  aware  of any  pending  or  threatened  material
liability for which the Company anticipates  becoming obligated to make payments
in connection with its obligations to indemnify Zing,  there can be no assurance
that   such   indemnification   obligations   could   not  arise  or  that  such
indemnification obligations would not be material to the Company.

Under the terms of the credit  facility  referred  to above,  the  Company  will
receive a $1,500,000 revolving line of credit to be used for working capital and
equipment  acquisitions.  The facility will be for a three year term and will be
guaranteed by Zing.  Interest on the borrowings  will be a variable rate tied to
the Bank's prime rate. All personal  property of the Company will  collateralize
the borrowings.  In addition to the formal agreements  mentioned above, Zing has
agreed to perform  the  following  duties  and  agreed to render  the  following
services: to advise in the development of the Company's business plan; to advise
the  Company  with  respect  to  and to  negotiate  material  agreements  on the
Company's behalf; to coordinate  communications with the Company's stockholders;
to  advise  the  Company  with  respect  to and to  negotiate  acquisitions  and
financing;  to assist in preparing and filing the Company's  reports required by
applicable  securities laws and rules of applicable stock  exchanges;  to review
and supervise the Company's  accounting  department and information systems from
time to time and suggest  revisions  and changes  thereto;  and to perform  such
further  services  as  mutually  agreed to. In regard to the  duties  enumerated
above, the Chief Financial Officer,  Controller and Office Administrator of Zing
will  spend a  portion  of their  time and be placed  on the  Company's  payroll
accordingly.

     The undersigned registrant hereby undertakes that:

     (A) The registrant will file, during any period in which it offers or sells
securities, a post-effective amendment to this registration statement to:

                (i) Include any prospectus  required by section  19(a)(3) of the
                    Securities Act;

               (ii) Reflect  in  the  prospectus  any  facts  or  events  which,
                    individually or together,  represent a fundamental change in
                    the information in the registration statement; and

              (iii) Include any  additional or changed  material  information on
                    the plan of distribution.

     (B) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 (the "Securities  Act") 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 Securities 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


                                       65

<PAGE>

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 Securities Act and will be governed by
the final adjudication of such issue.

         (C) For  determining  any  liability  under  the  Securities  Act,  the
registrant will treat 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  under Rule  424(b)(1) or (4)
under the Securities Act as part of this  registration  statement as of the time
the Securities and Exchange Commission declared it effective.

         (D) For  determining  any  liability  under  the  Securities  Act,  the
registrant  will treat each  post-effective  amendment  that  contains a form of
prospectus as a new  registration  statement for the  securities  offered in the
registration statement,  and that offering of the securities at that time as the
initial bona fide offering of those securities.

ITEM 4. UNREGISTERED SECURITIES ISSUED OR SOLD WITHIN ONE YEAR.

     The  registrant has not issued or sold any securities and Zing has not sold
any securities of the Company within one year prior to filing this  registration
statement which were not registered under the Securities Act. Zing has issued an
aggregate  of 17,534  shares of its common stock in the past year to six persons
who exercised common stock purchase warrants.

     subject to redemption by the  Corporation  and the times,  prices and other
     terms and  provisions  upon which the shares of the series may be  redeemed

     the amount per share payable in case of  redemption,  which amount may vary
     under different conditions and at different redemption dates;

          (4)  Whether or not the  shares of the series  shall be subject to the

     shares of that series;

          (8) Any other powers, preferences and relative participating, optional
     or other special rights,  and  qualifications,  limitations or restrictions
     thereof,  of the shares of such series,  as the Board of Directors may deem
     advisable  and as shall not be  inconsistent  with the  provisions  of this
     Certificate of Incorporation.

     The  holders  of  shares of the  Preferred  Stock of each  series  shall be
entitled to receive,  when and as  declared  by the Board of  Directors,  out of
funds legally available for the payment of dividends,  dividends (if any) at the

entitled upon  liquidation or dissolution or upon the distribution of the assets
of the  Corporation  to  such  preferences  as  provided  in the  resolution  or
resolutions  creating such series of Preferred  Stock,  and no more,  before any
distribution  of the assets of the  Corporation  shall be made to the holders of
shares of the Common  Stock.  Whenever  the  holders of shares of the  Preferred
Stock shall have been paid the full amounts to which they shall be entitled, the
holders of shares of the Common Stock shall be entitled to share  ratably in all

indebtedness  may be  issued,  sold or  otherwise  disposed  of by the  Board of
Directors on such terms and for such  consideration,  so far as may be permitted
by law,  and to such person or persons as the Board of Directors in its absolute
discretion may deem advisable.

     FIFTH: The Corporation is to have perpetual existence.

     SIXTH: The private property of the stockholders shall not be subject to the

                                        3


<PAGE>



     SEVENTH:  New  By-laws  may be  adopted  or the  By-laws  may be amended or
repealed by a vote of holders of two-thirds  (66-2/3%) of the outstanding  stock
of the  Corporation  entitled  to vote  thereon.  By-laws  may also be  adopted,
amended or repealed by resolutions adopted by the affirmative vote of a majority
of the directors and as provided or permitted by law;  provided,  however,  that
(a) the  Board of  Directors  may not  repeal  or amend a Bylaw  adopted  by the
shareholders;  and (b) any By-law amendment adopted,  amended or repealed by the
Board of Directors  increasing  or reducing the  authorized  number of directors
shall  require a  resolution  adopted by the  affirmative  vote of not less than
two-thirds (66-2/3%) of the directors.

     EIGHTH:  (a) The number of directors of the Corporation shall be the number
fixed  from  time  to  time  in  the  manner  provided  by  the  By-laws  of the
Corporation,  pursuant to a resolution adopted by a majority of the total number
of authorized  directors (whether or not there exist any vacancies in previously
authorized  directorships  at the time such resolution in presented to the Board
for  adoption),  but in no event  shall such  number be fewer than three (3) nor
more than ten (10).

     (b) If at any time the Corporation  shall have more than three (3) but less
than seven (7)  directors,  then at the first  annual  meeting  of  stockholders
thereafter,  the Board of Directors  shall be divided into two classes with each
class to be as nearly  equal in number as  possible,  with the term of office of
the first  class to expire at the  annual  meeting of  stockholders  held on the
first  anniversary of the annual meeting at which the Board is first  classified
and the term of office of the second  class to expire at the  annual  meeting of
stockholders  held on the second  anniversary of the annual meeting at which the
Board is first classified. At each annual meeting of stockholders following such
initial  classification  and  election,   directors  elected  to  succeed  those
directors  whose terms expire shall be elected for a term of office to expire at
the second succeeding annual meeting after their election.  Notwithstanding  the
preceding provisions of this paragraph (b) of this Article EIGHTH, if the number
of directors shall be more than six (6), at the next  succeeding  annual meeting
of stockholders  after such increase,  the directors shall be divided into three
classes,  as nearly equal in number as  possible.  At such annual  meeting,  one
class  shall be  elected  for a term  expiring  at the next  annual  meeting  of
stockholders,  the second  class  shall be elected  for a term  expiring  at the
second succeeding  annual meeting of stockholders,  and the third class shall be
elected  for  a  term  expiring  at  the  third  succeeding  annual  meeting  of
stockholders.  At each  annual  meeting  following  that at which  the  Board is
initially classified and elected in three classes,  directors elected to succeed
those  directors  whose terms expire shall be elected for a term expiring at the
third succeeding annual meeting of stockholders after their election,  and until
their  successors  shall be elected and qualified.  No increase in the number of
directors shall shorten the term of any incumbent director.

     (c) Except as otherwise  fixed pursuant to the provisions of Article EIGHTH
hereof, newly created directorships resulting from any increase in the number of
directors  and any  vacancies  on the Board of Directors  resulting  from death,
resignation,  disqualification,  removal or other cause may be filled (i) by the
affirmative  vote of a majority of the remaining  directors  then in office even
though  less  than a quorum of the Board of  Directors,  or by a sole  remaining
director,  or (ii) by the affirmative vote of the holders of at least two thirds
(66-2/3%) of the total voting power of all outstanding  shares of stock entitled
to vote generally in the election of directors. Any director


                                        4
<PAGE>


elected in  accordance  with the  preceding  sentence  shall hold office for the
remainder of the full term of the  directorship  for which the vacancy  occurred
and until such director's  successor  shall have been elected and qualified.  No
decrease in the number of directors  constituting  the Board of Directors  shall
shorten the term of any incumbent directors.

     (d) Except as otherwise  fixed pursuant to the provisions of Article EIGHTH
hereof,  any  director,  or the entire Board of  Directors,  may be removed from
office at any time only for  cause and only (i) by the  affirmative  vote of the
holders of not less than  two-thirds  (66-2/3%) of the total voting power of all
outstanding  shares of stock  entitled  to vote  generally  in the  election  of
directors,  voting together as a single class, or (ii) by action of the Board of
Directors.

     (e) Except as otherwise  required by law,  special meetings of stockholders
of the  Corporation  may be called only by the  Chairman of the Board,  the Vice
Chairman  of the Board,  if any,  the  President  or a majority  of the Board of
Directors,  or by the  unanimous  vote of a committee  of the Board of Directors
which has been duly  designated  by the Board of  Directors  and whose power and
authority,  as provided,  in a duly adopted resolution of the Board of Directors
or in the Bylaws of the Corporation, include the power to call such meeting.

     NINTH: (a) Subject to the provisions of any series of Preferred Stock which
may at the time be outstanding  and  convertible  into shares of Common Stock of
this  Corporation,  the affirmative  vote of at least 66-2/3% of the outstanding
shares of Common Stock held by stockholders other than the "Related Corporation"
(as hereinafter defined), shall be required for the approval or authorization of
any "business combination" (as hereinafter defined) of this Corporation with any
Related Corporation;  provided,  however, that such voting requirement shall not
be applicable if:

          (1) The business combination was approved by the Board of Directors of
     the  Corporation  either  (a)  prior  to the  acquisition  by such  Related
     Corporation  of  the  beneficial   ownership  of  10%  or  requisition  the
     outstanding  shares of the Common  Stock of the  Corporation,  or (b) after
     such acquisition,  but only so long as such Related  Corporation has sought
     and obtained  the  unanimous  approval by the Board of  Directors  for such
     acquisition prior to such acquisition being consummated; or

          (2) The business  combination is solely between this  Corporation  and
     existing Related  Corporations as of the date of filing of this amended and
     restated Certificate of Incorporation;

          (3) The business  combination is solely between this  Corporation  and
     another corporation, 50% or more of the voting stock of which is owned by a
     Related  Corporation;  provided that each  stockholder of this  Corporation
     receives the same type of  consideration  in such transaction in proportion
     to his stockholdings; or


                                        5


<PAGE>



          (4) All of the following conditions are satisfied:

               A. The cash or fair market value of the  property,  securities or
          other  consideration  to be  received  per share by  holders of Common
          Stock of this Corporation in the business combination is not less than
          the higher of (i) the  highest per share  price  (including  brokerage
          commissions, soliciting dealers' fees, dealer-management compensation,

next annual  meeting of  Stockholders,  the second  class shall be elected for a
term of office expiring at the second succeeding annual meeting of Stockholders,

DGCL as the same exists or,  subject to Section  6.4 of this  Article  Six,  may
hereafter be amended,


                                       10

<PAGE>

indemnify any director or officer of the  Corporation or subsidiary  thereof who
is or was  made  or  threatened  to be  made a party  to or is  involved  in any
threatened,  pending or completed action, suite or proceeding, whether or civil,
criminal,  administrative  or  investigative,  including any action by or in the
right of any other corporation of any type or kind,  domestic or foreign, or any
partnership,  joint venture,  trust,  employee benefit plan or other enterprise,
which any director or officer of the  Corporation or subsidiary is serving,  has
served or has agreed to serve in any capacity at the request of the  Corporation
by a majority of the Board of directors  who were not parties,  by reason of the
fact that he, his  testator  or  intestate,  is or was or had agreed to become a
director or officer of the  Corporation or  subsidiary,  or is or was serving or
has agreed to serve such other corporation,  partnership,  joint venture, trust,
employee  benefit plan or other enterprise in any capacity,  against  judgments,
fines, amounts paid or to be paid in settlement,  excise taxes or penalties, and
costs,  charges and expenses,  including attorneys' fees, incurred in connection
with such  action or  proceeding  or any  appeal  therein;  provided,  that such
officer acted in good faith and in a manner he  reasonably  believed to be in or
not opposed to the best interests of the Corporation;  provided,  further, that,
except as provided in Section 6.6 of this Article Six or as  otherwise  provided
by  agreement,   the  Corporation   shall  indemnify  any  such  person  seeking
indemnification  in connection with a proceeding (or part thereof)  initiated by
such person only if such  proceeding  (or part thereof) was authorized by Board.
This Article shall apply only to those officers who have been appointed pursuant
to  resolution  of  the  Board  of  the  Corporation  or  subsidiary,  or  whose
appointment was ratified thereby.

     6.2  Non-Exclusivity of Rights. The Corporation may indemnify any person to
whom the Corporation is permitted to provide  indemnification of the advancement
of expenses by


                                       11

<PAGE>

applicable law,  whether pursuant to rights granted pursuant to, or provided by,
the DGCL or other rights  created by (i) a resolution  of  Stockholders,  (ii) a
resolution   of   directors   or  (iii)   an   agreement   providing   for  such
indemnification,  it being expressly  intended that these by-Laws  authorize the
creation of other rights in any such manner.  The right to be indemnified and to
the  reimbursement or advancement of expenses incurred in defending a proceeding
in  advance  of its final  deposition  conferred  in this  Section  shall not be
exclusive  of any other  right  which any person may have or  hereafter  acquire
under  any  statute,  provision  of the  Charter,  By-laws,  agreement,  vote of
Stockholders or disinterested directors or otherwise.

     6.3  Expenses.  The  Corporation  shall,  from time to time,  reimburse  or
advance to any person  referred to in Section 6.1 of this  Article Six the funds
necessary  for  payment of  expenses,  including  attorneys'  fees,  incurred in
connection  with any  action or  proceeding  referred  to in Section  6.1,  upon
receipt of a written  undertaking  by or on behalf of such  person to repay such
amount(s) if a judgment or other final  adjudication  adverse to the director or
officer  establishes  that (i) his acts were  committed in bad faith or were the
result of active and deliberate dishonesty and, in either case, were material to
the cause of  action  so  adjudicated,  or (ii) he  personally  gained in fact a
financial profit or other advantage to which he was not legally entitled.

     6.4 Interpretation of Rights to Indemnification.  Any person entitled to be
indemnified  or to the  reimbursement  or advancement of expenses as a matter of
right  pursuant to this  Section may elect to have the right to  indemnification
(or  advancement of expenses)  interpreted on the basis of the applicable law in
effect at the time of the  occurrence  of the event or event  giving rise to the
action or  proceeding,  to the extent  permitted  by law, or on the basis of the
applicable law in effect at the time indemnification is sought.


                                       12

<PAGE>


     6.5 Other Rights.  The right to be indemnified or to the  reimbursement  or
advancement  of expenses  pursuant to this  Article Six (i) is a contract  right
pursuant  to  which  the  person  entitled  thereto  may  bring  suit  as if the
provisions  hereof  were set forth in a separate  written  contract  between the
Corporation  and the director or officer (ii) is intended to be retroactive  and
shall be  available  with  respect to event(s)  occurring  prior to the adoption
hereof and (iii) shall  continue to exist after the  rescission  or  restrictive
modification hereof with respect to events occurring prior thereto.

     6.6 Right of Claimant to Bring Suit. If a request to be indemnified is made
under this Article Six, the Board shall make a determination pursuant to Section
145 (d) of the DGCL  within 60 days after such  request as to whether the person
so requesting  indemnification is entitled to indemnification under this Article
Six and the Delaware General  Corporation Law. If a request to be indemnified or
for the  reimbursement  or advancement of expenses under this Article Six is not
paid in full by the  Corporation  within 60 days after a written  claim has been
received by the Corporation,  the claimant may at any time thereafter bring suit
against  the  Corporation  to  recover  the unpaid  amount of the claim and,  if
successful in whole or in part,  the claimant  shall be entitled to be paid also
the expense of prosecuting  such claim. It shall be a defense to any such action
(other  than an action  brought  to  enforce a claim for  expenses  incurred  in
defending any proceeding in advance of its final  disposition where the required
under  undertaking,  if any is required,  has been tendered to the  Corporation)
that the claimant has not met the standards of conduct which make it permissible
under the DGCL or hereunder  for the  Corporation  to indemnify the claimant for
the  amount  claimed,  but the burden of proving  such  defense  shall be on the
Corporation. Neither the failure of the Corporation (including its Board,

                                       13

<PAGE>


independent  legal  counsel or its  Stockholders)  to have made a  determination
prior to the commencement of such action that indemnification of the claimant is
proper  in the  circumstances  because  he has met the  applicable  standard  of
conduct set forth in the DGCL or hereunder,  nor an actual  determination by the
Corporation (including its Board, independent legal counsel or its Stockholders)
that the claimant has not met such  applicable  standard of conduct,  shall be a
defense to the action or create a presumption  that the claimant has not met the
applicable standard of conduct.

     6.7. Insurance.  The Corporation may maintain insurance, at its expense, to
protect itself and any director,  officer,  employee or agent of the Corporation
or another corporation,  partnership,  joint venture,  trust or other enterprise
against any such  expense,  liability  or loss,  whether or not the  Corporation
would have the power to indemnify such person against such expense, liability or
loss under the DGCL.

     6.8.  Separability.  If this  Article  Six or any portion  hereof  shall be
invalidated  on any  ground by any  court of  competent  jurisdiction,  then the
Corporation shall  nevertheless  indemnify each director,  officer,  employee or
agent of the  Corporation  as to the  costs,  charges  and  expenses  (including
attorneys' fees),  judgments,  fines and amounts paid in settlement with respect
to any action, suit or proceeding,  whether civil,  criminal,  administrative or
investigative, including an action by or in the right of the Corporation, to the
fullest  extent  permitted  by any  applicable  portion of this Article Six that
shall  not  have  been  invalidated  and  to the  fullest  extent  permitted  by
applicable law.

Gentlemen:

         We furnish this opinion to be filed as Exhibit 5.1 to the  Registration
Statement on Form SB-1 (the  "Registration  Statement")  of Transition  Analysis
Component  Technology,  Inc. (the "Company"),  Registration No.  333-20709.  The
Registration Statement relates to the proposed public offering by the Company of
498,447 shares of Common Stock in a spinoff transaction  involving  shareholders
of Zing  Technology,  Inc., as more  particularly  described in the Registration
Statement.

         We are familiar with the proceedings taken by the Company in connection
with the Registration Statement and the proposed public offering.

         On the basis of the foregoing and such other  investigations as we have
deemed  necessary  in  connection  with this  opinion,  and,  assuming  that the
Registration  Statement  becomes and remains effective and that applicable state
securities  laws are  complied  with,  we are of the opinion  that the shares of
Common Stock to which the Registration  Statement  relates will, when issued and
sold in the  manner  contemplated  in the  Registration  Statement,  be  legally
issued, fully paid and nonassessable shares of Common Stock.

         We hereby  consent to the filing of this  opinion as Exhibit 5.1 to the
Registration  Statement.  We further  consent to the reference to our firm under
the caption "Legal Matters" in the Prospectus  which is part of the Registration
Statement.


                                         Very truly yours,


                                         /s/

automatically  extend the term of this  Employment  Agreement for one additional
period of five (5) years on the same terms and conditions contained herein, from
the period May 1, 1992 through April 30, 1997.  Such election shall be exercised
by the Employee giving the Employer written notice of the Employee's decision to
so extend  this  Employment  Agreement  on a date  which  shall be no later than
January 31, 1992.  The Employee shall only have the right to elect to extend his
term of employment if, at the time of such election and at the  commencement  of
the second five year term of employment hereunder, the Employee shall then be an
employee of the Employer,  this Employment  Agreement shall be in full force and
effect, and the Employee shall not be in default hereunder.  Notwithstanding the
foregoing,  this Employment  Agreement and the Employee's  employment  hereunder
shall be subject to  earlier  termination  pursuant  to the  provisions  of this
Employment Agreement (said period during which the Employee is employed pursuant
to this Employment Agreement is herein referred to as the "Employment Period").

     5. Employee's Compensation.

     (a) The Employee shall receive as his entire  compensation for all services
rendered to the  Employer  with respect to each Year of the  Employment  Period,
subject to applicable  withholding for federal income tax, FICA, state and local
income  taxes and other  appropriate  charges,  the total of (i)  $120,000  (the
weekly portion of such amount,  being  $2,307.69,  shall be paid to the Employee
weekly in arrears) and (ii) an amount equal to five percent (5%) of all revenues
representing  payment (or partial  payment) of each Invoice Price (such revenues
being hereinafter called the "Invoice Payments") received by the Employer during
each Year or,  with  respect  to the last Year of  Employment  Period,  received
during or after such Year with respect to such Year,  except that if any Year of
the term of this  Employment  Agreement  shall be for less  than a twelve  month
period, the Employee's right to receive weekly payments of $2,307.69 referred to
in Paragraph 5(a)(i)

                                        3


<PAGE>


hereof  shall  continue  only so long as  required  by  Paragraph  9 hereof.  In
addition to the foregoing,  the Employee's  compensation shall be subject to the
following additional terms:

     (I)  A.   The Employer and the Employee shall calculate  monthly the amount
               of Invoice Payments received during the month preceding the month
               in  which  the  calculation  is made  (the  amount  of each  such
               calculation  being  herein  called the "Monthly  Estimate"),  and
               during  each  month  of the  Employment  Period,  shall  pay  the
               Employee an amount  equal to five  percent  (5%) of such  Monthly
               Estimate.

          B.   The Employee  shall continue to have a right to receive an amount
               equal to five  percent  (5%) of all  Invoice  Payments,  whenever
               received by the Employer,  which are based on invoices  dated and
               billed within the  Employment  Period and  forwarded  within such
               period to  customers  of the  Employer  with respect to completed
               goods  and   services;   provided,   however,   for  purposes  of
               calculating the maximum  compensation to which the Employee shall
               be  entitled  in any Year,  such  Invoice  Payments,  if received
               subsequent to the last Year of the  Employment  Period,  shall be
               deemed to have been received in such last Year.

     (II) A.   Notwithstanding  the  provisions of division I of this  Paragraph
               5(a),  the maximum  compensation  which the  Employee may receive
               under this  Paragraph  5(a) with respect to any twelve month Year
               shall not exceed  $350,000 on an annual  basis,  subject  only to
               adjustment as otherwise set forth at Paragraph 5(a) IIC hereof.

          B.   In  calculating  the maximum  compensation  to which the Employee
               shall be  entitled in any Year less than a twelve  month  period,
               such

                                        4


<PAGE>


               compensation  shall not exceed an amount  equal to the product of
               $350,000  and a  fraction,  the  numerator  of which shall be the
               number of days in such Year which  shall be  included  within the
               Employment Period and the denominator of which shall be 365.

          C.   The $350,000  annual maximum set forth in this  Paragraph  5(a)II
               shall be adjusted  within  thirty (30) days after the end of each
               Year to reflect,  with respect to the next  succeeding  Year, the
               increase in the United States National Consumer Price Index, "ALL
               URBAN  CONSUMER'S  (C.P.I.  - U.) (1967-100),  as compiled by the
               United States Bureau of Labor  Statistics for each such Year just
               completed; provided, however, that in no event shall the increase
               to such annual maximum exceed $10,000 for any such Year.

          (ii) With respect to each annual auditing period, the certified public
               accountants  auditing the books and records of the Employer shall
               make a final  determination of the Invoice  Payments  received by
               the Employer  for such period,  and the Employer and the Employee
               shall   make  any   necessary   adjustment   in  the   Employee's
               compensation  for such period in the event an  overpayment  or an
               underpayment has been made to the Employee. The decisions of such
               certified public accountants shall be conclusive and binding.

     (b) The parties hereto acknowledge that to the date hereof the Employee has
been  employed  by Zeus and,  although  not an  employee  of Zeus as of the date
hereof, may hereafter be called upon to contribute  additional services to Zeus.
The  Employee  agrees  that Zeus may  contract  with the  Employer  for up to 25
percent  of the  Employee's  time and  services  in or with  respect to any Year
within the Employment  Period.  The Employee  agrees to perform such services on
behalf of Zeus as shall be the subject of a separate  agreement between Zeus and
Employer. Notwithstanding

                                        5


<PAGE>



any services so rendered to Zeus, the Employer shall be solely  responsible  for
the payment of all compensation due to the Employee  pursuant to this Employment
Agreement.  The  Employee  shall not be entitled to any  separate or  additional
compensation by virtue of any services so rendered to Zeus.

     (c) In addition to the  compensation  provided for in this Paragraph 5, the
Employee  shall be entitled to be reimbursed for  reasonable  business  expenses
necessarily  incurred by him in the  performance of his duties  hereunder,  upon
presentation  of vouchers  indicating  the amount and  business  purpose of each
expenditure,  with such back-up  documentation  as the Employer shall reasonably
require  to  comply  with  the  requirements  of the  Internal  Revenue  Service
regarding   substantiation   of  travel,   entertainment   and  other   business
expenditures.  Unless such  expenses  have been  included in a budget or budgets
previously approved by the Board of Directors of the Employer, the same shall be
subject to review and approval by the Board of Directors,  which  approval shall
not be unreasonably withheld or delayed.

     (d) The Employee  shall be eligible to  participate  in all pension,  group
health,  life  insurance,  hospital and medical plans and in all other  employee
"fringe"  benefits of the Employer which are generally  provided to employees of
the  Employer  or to  employees  of Zeus  (or any  subsidiaries  of  Zeus)  with
responsibilities and positions  equivalent to those of the Employee.  During the
term of this  Employment  Agreement,  the Employer shall obtain and maintain for
the benefit of the Employee,  insurance in the amount of $200,000 on the life of
the Employee.  The Employee (or any person  selected by the Employee),  shall be
the owner of such  policy.  The  foregoing  provisions  shall be  binding on the
Employer  only so long as the Employee  remains  insurable  without any material
increase in  premiums  because of health  related  reasons of the  Employee.  In
addition to the foregoing,  the Employer  intends to develop a stock option plan
in which the Employee will be permitted to participate.

     (e) Until June 30,  1990,  the  Employee  shall be entitled to three weeks'
annual  vacation  with pay. From and after July 1, 1990,  the Employee  shall be
entitled to four weeks annual  vacation with pay.  Each such  vacation  shall be
prorated for any portion of a Year within the


                                        6


<PAGE>



Employment Period.  Such vacation shall be taken at such time or times so as not
to interfere with the Employee's duties to the Employer.  The Employee shall not
be entitled to accumulate  vacation from one Year to the next Year without Board
approval.

     (f) The  parties  hereto  recognize  that  from  time to time Zeus (and any
individual,  partnership,  corporation,  trust or other entity that  directly or
indirectly, through one or more intermediaries,  controls or is controlled by or
is under common control with Zeus ("control"  meaning,  for the purposes of this
provision,  50% or more voting control or equity)  hereinafter  referred to as a
"Zeus Related  Person") may make loans to the Employer instead of making capital
contributions  to the  Employer.  In such event,  the  Employer and the Employee
agree that any  repayment of the  principal  of such loans (but not  including a
repayment  in which  the funds  therefor  are being  provided  by a third  party
institutional  lender),  to Zeus (and any and all Zeus Related  Persons) will be
matched by the payment of a separate amount to the Employee, such that the ratio
of the principal  amount paid to Zeus (and any and all Zeus Related Persons) and
the separate  amount paid to the Employee will be in the same ratio as the stock
ownership of Zeus (and any and all Zeus Related  Persons) will be matched by the
payment  of a  separate  amount  to the  Employee,  such  that the  ratio of the
principal  amount paid to Zeus (and any and all Zeus  Related  Persons)  and the
separate  amount  paid to the  Employee  will be in the same  ratio as the stock
ownership of Zeus (and any and all Zeus Related Persons) in the Employer will be
to the stock  ownership of the  Employee in the  Employer.  Notwithstanding  the
foregoing,  any payments made to the Employee  pursuant to this  Paragraph  5(f)
shall not be subject to the maximum  compensation  limitations set forth in this
Employment Agreement,  nor shall such payments be credited against other amounts
payable to the  Employee  pursuant  to  Paragraph  5(a)  hereof.  The  foregoing
provision shall be  inapplicable  from and after the date at which any or all of
the shares of stock of the  employer  shall be  registered  under  Section 12 or
15(d) of the Securities Exchange Act of 1934, as amended.

     6. Non-Competition.  The Employer and the Employee recognize and agree that
the  Employee's  services are special and unique,  and that for these  reasons a
covenant  on the  Employee's  part not to compete  anywhere  in the  continental
United States during the Employment Period and


                                        7


<PAGE>



for a reasonable  period after any termination of this  Employment  Agreement is
essential  to protect  the  business of the  Employer.  The  restrictions  to be
imposed on the Employee pursuant to this Paragraph 6 shall not be applicable if,
and only if, the Employee's  employment  hereunder shall have been terminated by
the Employer  "without good cause",  as more particularly set forth at Paragraph
8(d) hereof.  Accordingly,  the Employer and the Employee  agree that during the
Employment  Period  and (i) for a period of six  months  commencing  immediately
after the Employment  Period, in the event the Employment Period shall terminate
pursuant  to  Paragraph  8(a) (iii)  hereof,  and (ii) for a period of two years
commencing  immediately after the Employment Period, in the event the Employment
Period shall terminate for any other reason (except a termination  "without good
cause" as hereinabove described), the Employee will not, directly or indirectly,
including as an officer, director, employee,  consultant, partner of any entity,
or as a  stockholder  owning  more than 10% of a  corporation  whose  shares are
publicly traded, engage in any business or solicit or accept any accounts in the
field of military  electronic  component service data management or in any other
field in which the Employer (Transition Analysis Component Technology,  Inc.) is
actively engaged within the twelve (12) month immediately  preceding the date of
termination of the Employment period.

     It is recognized by the parties  hereto that actual damages for breach of a
covenant of this nature are difficult if not impossible to prove with precision;
therefore,  except as limited  herein it is agreed  that this  agreement  not to
compete shall be enforceable by prohibitory injunction.

     7. Records. All reports,  records,  contracts,  memoranda,  correspondence,
surveys or other writings,  information or data prepared,  learned or discovered
by the Employee or furnished to him during the Employment  Period, or during any
prior  period in which he shall have been  employed  at Zeus,  shall  become and
remain the sole and exclusive  property of the Employer or Zeus, as the case may
be, for all purposes and uses whatsoever.  Throughout the Employment  Period and
thereafter,  the Employee shall not divulge,  furnish or make  accessible to any
third  party,  and shall  maintain  the  confidentiality  of,  all  confidential
information or proprietary  property  prepared,  learned or discovered by him or
furnished  to him during  the  Employment  Period or during any prior  period in
which he shall


                                        8


<PAGE>



have been employed at Zeus,  including,  without  limitation,  any and all trade
secrets, customer lists, contracts,  costs, sales or other financial or business
data or information.

     8. Termination of Employment.

     (a) The  Employment  Period shall  terminate upon the earliest of the dates
specified below:

          (i) the  close of  business  on the date as of  which  the  Employment

          (ii) the close of  business on the date sixty (60) days after the last
          day of the  month  in  which  the  death of the  Employee  shall  have

          (iii) the close of business on the date as of which the Employer shall
          have  given the  Employee  written  notice of the  termination  of his
          employment  hereunder as a result of a  "disability"  for the required
          period having occurred (as defined in Paragraph 8(b) hereof);

          (iv) the close of business on the date as of which the Employee  shall
          terminate his  employment  hereunder in violation of the terms of this
          Employment Agreement; or

          (v) the close of business on the date as of which the  Employer  shall
          have  given the  Employee  written  notice of the  termination  of his
          employment  for "good  cause" or  "without  good cause" (as defined in
          subparagraphs (c) and (d) of this Paragraph 8).

     (b) For purposes of this Employment Agreement,  the term "disability" shall
mean that by reason of a physical or mental illness which has continued for more

                                        9


<PAGE>



twelve (12) month period, the Employee has been  substantially  unable to render
services of the character  contemplated by this Employment Agreement (reasonable
vacation excepted).

     (c) For purposes of this Employment Agreement,  the term "good cause" shall
mean that any one of the following conditions exists or any one of the following
events has  occurred:  (i)  continued  refusal by the  Employee to perform  such
duties as may  reasonably be delegated or assigned to him,  consistent  with his
position,  by the Employer;  (ii)  substantial  and continued  inattention to or
continued  neglect by the  employee of his duties  hereunder;  or (iii)  willful
misconduct or gross negligence,  theft,  fraud,  embezzlement or conviction of a
felony by the Employee.

     (d)  Termination  "without  good  cause"  shall  mean  any  termination  of
employment  under  Paragraph  8(a)(v) hereof which is not a termination for good
cause, or which is not a termination as a result of the occurrence of any of the
events described at Paragraph 8(a)(i), (ii), (iii) or (iv) hereof.

     9. Effect of Termination.

     (a) In the event that the  Employment  Period is terminated  for any reason
provided in Paragraph 8 hereof other than a termination  without good cause, the
Employer shall only be liable for that portion of the annual gross  compensation
provided  for in  Paragraph  5 hereof to which the  Employee  shall be  entitled
during or with  respect to the  Employment  Period,  plus an amount equal to the
product of (i)  $2,307.69  and (ii) the number of twelve  month  periods (or any
part of any such period) which have elapsed between July 5, 1978 and the date of
such termination.

     (b) In the event that the  Employment  Period is  terminated  without  good
cause, as provided in Paragraph 8(a)(v) hereof, the Employee's compensation will
continue until April 30, 1992, if such termination  shall have occurred prior to
such date or April 30, 1997, if such termination shall have occurred  subsequent
to April 30, 1992 and prior to April 30, 1997,  provided the Employee shall have
exercised his option to renew his employment hereunder. Notwithstanding anything
herein to the contrary, any compensation otherwise payable hereunder shall cease
on the close of business



                                       10


<PAGE>



on the date  sixty  (60) days after the last day of the month in which the death
of the Employee has occurred.

     (c) The Employer  shall pay any funds to which the Employee is entitled and
which is set forth in this  Paragraph  9 to the  Employee,  his  estate or legal
representative, as the case may be.

     (d) In the event that during the  Employment  Period the Employee  shall be
entitled to and shall actually  receive  disability  benefits  (other than those
paid for exclusively by the Employee), the benefits so received shall reduce the
compensation  to be paid to the  Employee  pursuant to Paragraph 5 hereof to the
extent of the benefits so received.

     (e) The Employee hereby consents to the Employer obtaining insurance on the
life of the  Employee,  the  proceeds  of  which  shall be the  property  of the
Employer or its designee.  The Employee  shall  cooperate with the Employer with
respect to any  examination  or  documentation  required  of the  Employee  with
respect to the obtaining of such insurance.

     10. Arbitration.

     10.1  Disputes  Determined  by  Arbitration.   Any  and  all  disputes  and
controversies  arising out of or in connection with this Employment Agreement or
with respect to the construction and  interpretation  hereof,  or concerning the
rights of any one or more parties hereto or the  respective  obligations of each
party hereto to each other party hereto,  shall be determined by  arbitration in
the County of Westchester,  in accordance with and pursuant to the then existing
rules  of  the  American  Arbitration  Association.  The  decision  of a  single
arbitrator  chosen by said Association  shall be binding upon the parties hereto
with the same  force  and  effect  as a  decision  or  judgment  of any court of
competent  jurisdiction.  Any party  hereto shall be entitled to have a judgment
based upon the  decision  of said  arbitrator  entered  by a court of  competent
jurisdiction.


                                       11

Any party hereto shall be entitled to compel arbitration hereunder.

     10.3  Expenses.  The expenses of such  arbitration  shall be borne  equally
between or among the parties seeking the arbitration.

     11. Effective Date. This Employment  Agreement shall become effective as of

binding  upon and inure to the  benefit  of and be  enforceable  by the  parties
hereto, their respective  successors and assigns,  executors,  administrators or
other legal representatives and their respective legatees and distributees.

     12. Notices.  Any notice required or permitted by this Employment Agreement
shall be given by  registered  or  certified  mail,  return  receipt  requested,

the parties relating to the subject matter hereof,  and there are no agreements,
representations  or  warranties  relating to the  subject  matter not herein set

or understandings relating to the subject matter hereof. No modification of this
Employment  Agreement shall be valid unless in writing and signed by the parties
hereto.  A waiver of the  breach  of any term or  condition  of this  Employment
Agreement shall not be deemed to constitute a waiver of any subsequent breach of
the same or any other term or condition.

     15.  Unenforceability.  If any provision of this Employment Agreement shall
to  any  extent  be  held  invalid  or   unenforceable,   such   invalidity  and
unenforceability  shall not affect the remaining  provisions  hereof which shall

     16.  Miscellaneous.  The Employee  warrants and represents that there is no
other  agreement in force which prohibits him from entering into this Employment
Agreement or otherwise


                                       12


<PAGE>



performing  services for the  Employer,  or which will be violated in any way by
his entering into this Employment Agreement.

     17. Employee's Auditing of Employer's Books and Records

     (a) The  Employer  agrees  to make and keep  full and  accurate  books  and
records  describing all activities under this Agreement in sufficient  detail to
enable all compensation  payable to the Employee hereunder to be determined.  In
addition,  the Employer  agrees to cause  certified  financial  statements to be
prepared  annually  by the  independent  auditors  of  the  Employer,  and  when
available to  distribute a copy thereof to the Employee.  During the  Employment
Period,  the  Employer  agrees to make  available  to the  Employee any internal
financial statements prepared for or by the Employer.

     (b) On  thirty  (30)  days  prior  notice  to the  Employer,  but not  more
frequently  than one time in any  twelve  month  period,  the  Employee  and his
certified public accountants and other auditors shall, with respect to any Year,
have limited access to such of the books and records of the Employer as shall be
reasonably  necessary to determine the  Employer's  Invoice,  Invoice Prices and
Invoice  Payments for such Year,  and the Employee  shall have the right to make
copies therefrom at the Employee's expense.  The Employee,  his certified public
accountants  and other  auditors,  but not more  frequently than one time in any
twelve month  period,  shall have such access at all  reasonable  times and from
time to time during normal  business hours during the term of this Agreement and
for a period of two (2) years after its expiration or  termination,  as the case
may be.

     (c) The Employee agrees to hold confidential all information learned in the
course of any examination of the Employer's books and records hereunder,  except
when it is  necessary  for the Employee to reveal such  information  in order to
enforce his rights under this Agreement, and except when compelled by law.

     18.  Conversion  To Dollars.  If any Invoice  Payment is made in a currency
other than  dollars,  such  Invoice  Payment  shall be  converted  into  dollars
promptly  after such Invoice  Payment is received by the Employer.  Payments due
and owing to the Employee  pursuant to the Agreement shall be paid in dollars to
the Employee.

2. Duties.

     2.1 Except as provided in Section 5 hereof,  during the Term, the Executive
shall devote such  professional  time, effort and energies to the performance of
his duties  hereunder,  and business and affairs of the Company as is reasonably

corporation and receiving compensation therefor,  (ii) making investments of any

<PAGE>




such activities do not interfere with the performance of the Executive's  duties
hereunder in any material respect.

6. Covenant Not to Compete; Confidentiality.

     6.1 The  Executive  acknowledges  and  recognizes  that the  services to be
performed by him hereunder are special,  unique and  extraordinary and that as a
result of his  employment  hereunder,  the Executive  will acquire  confidential
information  and  trade  secrets  concerning  the  operations  of  the  Company.
Accordingly,  the Executive agrees that until the later to occur of July 1, 1999
and the third anniversary of a change of control resulting in the termination of
Executive's employment pursuant to Section 8.3 below (the "Restriction Period"),
the  Executive  will not,  directly  or  indirectly,  as an  officer,  director,
stockholder,  partner, associate,  employee, consultant, owner, agent, creditor,

other corporation,  firm or business engaged in any business in competition with
that of the Company or (B) solicit, direct,  take-away,  contact or approach (I)
any employee of the Company in order to cause such  employee to terminate his or
her employment  with the Company,  or (II) any client of the Company in order to
cause such client to take its business to an unrelated  entity.  The Executive's
ownership,  directly or indirectly, of securities of any entity of not more than
two percent (2%)  of any class of the issued and outstanding  securities of such
entity shall not in any event be deemed to be a violation of the  provisions  of
this Section 6.1.

     6.2 Other than in the course of the  Company's  business  or as required by
law, the  Executive  shall not divulge to any person or entity,  during the Term
and thereafter,  any confidential or proprietary  information (i) concerning the
Company, (ii) concerning the conduct and details of the business of the Company,
or (iii)  which the  Executive  may have  acquired  in the  course  of, or as an
incident to, his  employment  by the Company.  For purposes of this Section 6.2,
confidential information shall not include any information which is now known by
the general public, or which becomes known by the general public other than as a
result of any violation of the terms of this Section 6.2 by the Executive.

7. Enforcement of Covenants.

     The Company shall be entitled, in addition to any other right and remedy it
may have, at law or in equity, to an injunction, without the posting of any bond
or other security,  enjoining or restraining the Executive from any violation or
threatened  violation of any of the  provisions  of Section 6, and the Executive
hereby consents to the issuance of such injunction;  provided, however, that the
foregoing  shall not prevent the Executive  from  contesting the issuance of any
such  injunction on the ground that no violation or threatened  violation of any
of the  provisions  of  Section  6 had  occurred.  If  any  of the  restrictions
contained  in Section 6.1 shall be deemed to be  unenforceable  by reason of the
extent,  duration or  geographical  scope thereof or  otherwise,  then the court
making such  determination  shall  reduce such  extent,  duration,  geographical
scope,  or other  provisions  thereof  pursuant to the  provisions of Section 16
hereof, and in its reduced form the restrictions  contained in Section 6.1 shall
then be enforceable in the manner contemplated hereby.

8. Termination.

     8.1 In the event of the  Executive's  death during the Term, the Employment
of the Executive  hereunder  shall terminate in which event the Executive or his
legal  representatives  shall be  entitled  to receive  any  amounts or benefits
accrued hereunder to which the Executive shall have been entitled on the date of
his death  (including  without  limitation the  Executive's  entitlements  under
Section 4 of this Agreement) but that shall not have been paid.

     NOW,  THEREFORE,  in consideration of the foregoing premises and the mutual
covenants contained herein, the parties hereto agree as follows:

     1. Indemnification.

     (a)  TACTech  will  indemnify  and save  harmless  Zing and its  directors,
officers,  employees,  agents and/or  affiliates  (each, a "TACTech  Indemnified
Party")  from any and all  costs,  expenses,  losses,  damages  and  liabilities
("Claim(s)") incurred or suffered, directly or indirectly,  (including,  without
limitation,  reasonable legal fees and expenses)  resulting from or attributable

<PAGE>

connection  with  any  information   concerning   TACTech  in  the  Registration
Statements  that was  furnished  by TACTech for  inclusion  in the  Registration
Statements or any part thereof.

     (b) Zing,  will  indemnify  and save  harmless  TACTech and its  directors,
officers,  employees, agents and/or affiliates (each, a "Zing Indemnified Party"
and,  together with each TACTech  Indemnified  Party,  without  distinction,  an
"Indemnified  Party") from any and all Claims incurred or suffered,  directly or
indirectly,  (including, without limitation, reasonable legal fees and expenses)
resulting  from or  attributable  to the  operation  of Zing  (i)  prior  to the
Distribution  (excluding the operation of TACTech);  (ii) after the Distribution
(excluding the operation of TACTech); and (iii) any claim, suit or other type of
proceeding  based upon,  arising out of or in  connection  with any  information
concerning  Zing in the  Registration  Statements that was furnished by Zing for
inclusion in the Registration Statements or any part thereof.

     2. Defense of Claim.

     (a) In the event an Indemnified Party receives notice of any claim asserted
or any action or  administrative  or other proceeding  commenced in respect of a
Claim for which  indemnity may be properly  sought under this Agreement  against
TACTech or Zing, as the case may be (the "Indemnifying  Party"), the Indemnified
Party shall give notice in writing to the Indemnifying  Party within thirty (30)
days of its receipt of such notice. Within thirty (30) days after the earlier of
(a) receipt by the Indemnifying Party of such notice from the Indemnified Party,
or (b) receipt of actual  notice by the  Indemnifying  Party from sources  other
than the  Indemnified  Party,  the  Indemnifying  Party may give the Indemnified
Party  written  notice of its  election  to conduct  the  defense of such claim,
action or proceeding at its own expense. If the Indemnifying Party has given the
Indemnified  Party  such  notice  of  election  to  conduct  the  defense,   the
Indemnifying  Party may conduct the defense at its expense,  but the Indemnified
Party shall nevertheless have the right to participate in the defense,  provided
such participation is solely at the expense of the Indemnified Party,  without a
right of further  reimbursement.  If the Indemnifying  Party has not so notified
the  Indemnified  Party in writing within the time period  provided above of its
election to conduct the defense of such Claim,  the  Indemnified  Party may, but
need not,  conduct,  at the Indemnifying  Party's  expense,  the defense of such
claim,  action or proceeding.  The Indemnified  Party may at any time notify the
Indemnifying  Party of its  intention to settle,  compromise or satisfy any such
claim, action or proceeding (the defense of which the Indemnifying Party has not
previously  elected  to  conduct)  and,  with the prior  written  consent of the
Indemnified  Party (which consent will not be unreasonably  withheld),  may make
such  settlement,  compromise  or  satisfaction,  at  the  Indemnifying  Party's
expense,   provided,   however,  that  the  Indemnifying  Party  may  make  such
settlement,  compromise or satisfaction without the prior written consent of the
Indemnified Party if such settlement,  compromise or satisfaction  constitutes a
release of the Indemnified Party in respect of such Claim.

     (b) Any settlement,  compromise or  satisfaction,  or any final judgment or
decree  entered in, or any Claim  defended in accordance  with the provisions of
this Paragraph 2 shall be final and binding on the parties hereto.


                                        2

in accordance with the provisions of this Paragraph 2.

     4.  Cooperation.  In  connection  with any  Claim  that is the  subject  of
indemnification,  each  party  shall  afford to the  Indemnifying  Party and its
accountants,  counsel and other  designated  representatives  reasonable  access

<PAGE>



instruments,  computer  data and other  information  insofar  as such  access is
reasonably  required by the Indemnifying Party in connection with the defense of

reasonable  efforts to make available to the  Indemnifying  Party,  upon written
request,  its  officers,  directors,  employees  and agents as  witnesses to the
extent that any such person may  reasonably be required in  connection  with the
defense or prosecution of any Claim.

     5. Waiver. The waiver by any party hereto of the breach of any provision of
this Agreement shall not operate or be construed as a waiver of any preceding or
succeeding breach and no failure by any party to exercise any right or privilege
hereunder shall be deemed a waiver of such party's rights or privileges or shall
be deemed a waiver of such party's rights  hereunder to exercise the same at any
subsequent time or times.

     6. Amendment.  This Agreement may be amended, modified or supplemented only
by written instrument executed by the party against whom enforcement is sought.

     7.  Governing  Law.  This  Agreement  shall be governed by and construed in
accordance with the laws of the State of Delaware.

more of the  provisions of this Agreement in any  jurisdiction  shall not affect
the validity,  legality or  enforceability of the remainder of this Agreement in
such  jurisdiction  or  the  validity,   legality  and  enforceability  of  this
Agreement,  including any such provision,  in any other  jurisdiction,  it being
intended  that all rights and  obligations  of the  parties  hereunder  shall be
enforceable to the fullest extent permitted by law.

     9.  Counterparts.   This  Agreement  may  be  executed  in  any  number  of
counterparts,  each of which shall be deemed to be an original, but all of which
together shall constitute one and the same instrument.

     10.  Succession and  Assignment.  This Agreement  shall be binding upon and
inure to the benefit of the parties hereto, and the Indemnified Parties and each
of their respective successors and assigns.

     11.  Acknowledgment  of  Securities  Laws  Policy  Against  Indemnification
Agreements.  Insofar  as  indemnification  for  liabilities  arising  under  the
Securities  Act of 1933 (the  "Securities  Act") may be permitted to  directors,
officers  and  controlling  persons  of the  TACTech  or  Zing  pursuant  to the
foregoing provisions,  or otherwise,  the parties acknowledge the opinion of the
Securities and Exchange  Commission that such  indemnification is against public
policy  as  expressed  in  the  Securities  Act  of  1933  and  is,   therefore,
unenforceable.  In the  event  that a claim  for  indemnification  against  such
liabilities  (other than the  payment by either of TACTech or Zing,  as the case
may be, of  expenses  incurred  or paid by a  director,  officer or  controlling
person of TACTech or Zing, as the case may be, 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, TACTech or Zing will,
unless in the opinion of its counsel the matter has been settled by  controlling
precedent, submit

                                        4


<PAGE>



to a court of appropriate jurisdiction the question whether such indemnification
by it is against  public policy as expressed in the  Securities  Act of 1933 and
will be governed by the final adjudication of such issue.


                                        5

Committee, contribute significantly to the Company.

           (b) Each Option shall be designated in the Option Agreement as either
an  Incentive   Stock  Option  or  a   Nonqualified   Stock   Option.   However,
notwithstanding such designations,  to the extent that the aggregate Fair Market
Value of the Common Stock with respect to which Options  designated as Incentive
Stock  Options are  exercisable  for the first time by any  Optionee  during any
calendar year (under all plans of the Company)  exceeds  $100,000,  such Options
shall be treated as Nonqualified Stock Options.
           
           (c) For purposes of Section 5(b), Options shall be taken into account
in the order in which they were granted, and the Fair Market Value of the Common
Stock shall be  determined as of the time the Option with respect to such Shares
is granted.

        6. Term of Plan. The Plan shall become  effective upon the latest of the
following two events to occur:  (a) approval of the Plan by the  stockholders of
the Company and (b) adoption of the Plan by the Board.  The Plan shall  continue
in effect for ten (10) years from the effective date,  unless sooner  terminated
in accordance with the provisions of section 15 of the Plan.

        7. Terms of Options.  Unless  otherwise  determined by the Committee and
set forth in the Option  Agreement,  Options granted  pursuant to the Plan shall
have the following terms:

           (a) The Option  exercise period price of the Options shall be no more
than ten (10) years from the date of the grant.

           (b) The per Share  exercise  price of the Options shall be determined
by the Committee and may be fixed at the time of grant, float in accordance with
a predetermined formula, 

                                       6

<PAGE>

or any combination thereof; provided, however, that (i)
in the case of Incentive  Stock  Options,  the exercise  price shall not be less
than 100% of the Fair Market  Value of the  Optioned  Stock on the date of grant
(or 110% of the Fair Market Value of the Stock  Optioned on the date of grant if
the optionee
owns more their 10% of the  Company's  outstanding  shares of Common  Stock) and
(ii) in the case of  Nonqualified  Stock Options,  the exercise price may not be
less  then 75% of the Fair  Market  Value of the  Optioned  Stock on the date of
grant.

           (c)  Options  shall  be  exercisable  at such  time or  times  as the
Committee shall determine at or subsequent to the grant date.

           (d) The  consideration  to be paid for the  Shares to be issued  upon
exercise of an Option,  including the method of payment,  shall be determined by
the  Committee  at the time of grant  and may be paid by  tendering  payment  by
certified  check,  wire transfer of same day funds or bank check.  The Committee
may  determine,  in its  discretion,  that  additional  forms of payment will be
permitted,  including,  but not  limited  to, by  delivery of Shares held by the
Participant,  together with any cash paid in connection with an exercise, having
a Fair  Market  Value  equal  to  the  exercise  price.  The  Committee,  in its
discretion,  may at any time prior to the exercise of an Option  determine  that
certain forms of payment may not be available to a particular Participant.

        8. Exercise of Option.

           (a) Each  option  may be  exercised  in  whole or in part;  provided,
however,  that no Option may be exercised  for a fraction of a share.  An Option
shall be deemed to be exercised  when written  notice of such  exercise has been
given to the Company in accordance with the terms of the Option Agreement by the
person  entitled  to  exercise  the Option and full  payment for the Shares with
respect to which the Option is exercised has been received by the Company.  Full
payment may, as

                                       7

<PAGE>

authorized by the Committee,  consist of any consideration and method of payment
allowable  under  Section 7(d) of the Plan.  Until the issuance (as evidenced by
the  appropriate  entry on the  books  of the  Company  or of a duly  authorized
transfer agent of the Company) of the stock certificate  evidencing such Shares,
no right to vote or receive dividends or any other rights as a stockholder shall
exist with respect to the Optioned  Stock,  notwithstanding  the exercise of the
Option.  The Company shall issue (or cause to be issued) such stock  certificate
promptly upon exercise of the Option.
                 
           (b) In no event shall any part of any Option be exercisable after the
date of  expiration  thereof  (the  "Expiration  Date"),  as  determined  by the
Committee pursuant to Section 7(a) above.

           (c)  Except as  otherwise  provided  by the  Committee  in the Option
Agreement,  any  portion  of a  Participant's  Option  that was not  vested  and
exercisable on the date of the termination of such Participant's  employment for
whatever  reason  shall  expire  and be  forfeited  as of such  date;  provided,
however, that: (i) if any Participant dies or becomes subject to any Disability,
such Participant's Option will expire 90 days after the date of his or her death
or  Disability,  but  in no  event  after  the  Expiration  Date,  (ii)  if  any
Participant  retires (with the approval of the  Committee or the Board),  his or
her Option will expire 90 days after the date of his or her  retirement,  but in
no event after the Expiration  Date, and (iii) if any  Participant is discharged
for any reason other than for Cause,  such  Participant's  Option will expire 30
days  after  the  date  of his or her  discharge,  but  in no  event  after  the
Expiration Date.

        9.  Non-Transferability of Options;  Limitations on Transfer of Optioned
Stock.

                                       8

<PAGE>

           (a)  Options  granted  under  the  Plan  may  not be  sold,  pledged,
assigned, hypothecated, transferred, or disposed of in any manner, other than by
will or by the laws of descent or distribution, and may be exercised, during the
lifetime of the Participant,  only by the Participant. In the event of the death
of a Participant,  the exercise of Options granted  hereunder shall be made only
by the executor or  administrator  of the estate of the deceased  Participant or
the person or persons to whom the deceased Participant's rights under the Option
shall pass by will or the laws of descent and distribution.

           (b) No  Participant  shall be permitted to sell,  dispose,  assign or
otherwise  transfer the Optioned Stock  underlying any Option until at least six
months have elapsed since the Participant acquired such Option.

           (c) Each  Option  and all  rights  granted  thereunder  shall  not be
transferable  other  than by will or the laws of  descent  and  distribution  or
pursuant to a qualified domestic relations order as defined by the Code or Title
I of the Employee  Retirement  Income  Security Act of 1974, as amended,  or the
rules  promulgated  thereunder,  and shall be exercisable  during the optionee's
lifetime   only  by  the   optionee   or  the   optionee's   guardian  or  legal
representative.

       10. Adjustments Upon Changes in Capitalization.

           In the event of a reorganization, recapitalization, stock dividend or
stock split,  or combination or other change in the shares of Common Stock,  the
Board or the  Committee  may,  in its sole  discretion,  in order to prevent the
dilution  or  enlargement  of  rights  under  outstanding  Options,   make  such
adjustments in the number and type of Shares  authorized by or granted under the
Plan,  the number and type of Optioned Stock and the exercise  prices  specified
therein as it may determine to be appropriate and equitable.

                                       9

<PAGE>

        11. Written  Agreement.  Each Option granted  hereunder to a Participant
shall be embodied  in a written  Option  Agreement  which shall be signed by the
Participant and by a duly authorized  officer of the Company for and in the name
and on behalf of the  Company  and shall be subject to the terms and  conditions
prescribed herein.

        12.  Listing,  Registration  and Compliance  with Laws and  Regulations.
Options shall be subject to the requirement that at any time the Committee shall
determine, in its discretion, that the listing, registration or qualification of
the Shares  subject to the  Options  upon any  securities  exchange or under any
state or  federal  securities  or other law or  regulation,  or the  consent  or
approval of any  governmental  regulatory  body,  is necessary or desirable as a
condition to or in  connection  with the granting of the Options or the issuance
or purchase of shares  thereunder,  no Options may be granted or  exercised,  in
whole or in part, unless such listing, registration,  qualification,  consent or
approval  shall  have been  effected  or  obtained  free of any  conditions  not
acceptable to the Committee. The holders of such Options will supply the Company
with such  certificates,  representations  and  information as the Company shall
request  and shall  otherwise  cooperate  with the  Company  in  obtaining  such
listing,  registration,  qualification,  consent  or  approval.  In the  case of
officers and other persons  subject to Section 16(b) of the Securities  Exchange
Act of 1934, as amended,  the  Committee may at any time impose any  limitations
upon  the  exercise  of an  Option  that,  in the  Committee's  discretion,  are
necessary or desirable in order to comply with such Section  16(b) and the rules
and regulations thereunder. If the Company, as part of an offering of securities
or  otherwise,  finds it  desirable  because  of  federal  or  state  regulatory
requirements to reduce the period during which any Options may be exercised, the
Committee  may,

                                       10
<PAGE>

in its discretion and without the Participant's  consent,  so reduce such period
on not less than 15 days' written notice to the holders thereof.

        13.  Rights of  Participants.  Nothing in this Plan shall (a)  interfere
with or limit in any way the right of the Company to terminate any Participant's
employment  at any  time  (with  or  without  Cause),  or (b)  confer  upon  any
Participant any right to continue in the employ of the Company for any period of
time or to continue  his or her  present  (or any other)  rate of  compensation.
Except as otherwise  provided  under this Plan or by the Committee in the Option
Agreement,  in the event of any  Participant's  termination of  employment,  any
portion  of such  Participant's  Option  that  was  not  previously  vested  and
exercisable will expire and be forfeited as of the date of such termination.  No
Employee shall have a right to be selected as a Participant,  or, having been so
selected, to be selected again as a Participant.

        14. Withholding of Taxes. The Company shall be entitled, if necessary or
desirable,  to withhold from any Participant from any amounts due and payable by
the Company to such Participant (or secure payment from such Participant in lieu
of withholding)  the amount of any withholding or other tax due from the Company
with respect to any Shares  issuable  under the Plan,  and the Company may defer
such  issuance  unless  indemnified  to its  satisfaction.  If  permitted by the
Committee,  in its sole  discretion,  a Participant may elect to pay withholding
tax  obligations by having the Company  withhold  Shares having a value equal to
the  amount  of tax  required  to be  withheld.  The  value of the  Shares to be
withheld  shall equal the Fair Market  Value of the Shares on the day the Option
is exercised.
 
        15.  Amendment,  Suspension  and  Termination  of Plan. The Board or the
Committee may suspend or terminate  the Plan or any portion  thereof at any time
and may  amend  it from  time to time 

                                       11
<PAGE>

in such  respects as the Board or the Committee  may deem  advisable;  provided,
however,  that no such amendment shall be made without  stockholder  approval to
the extent  such  approval is  required  by law,  agreement  or the rules of any
exchange  upon  which  the  Common  Stock  is  listed,  and no  such  amendment,
suspension  or  termination  shall  impair the rights of  Participants  affected
thereby.  No Options shall be granted  hereunder after the tenth  anniversary of
the  adoption of the Plan. 

        16. Amendment, Modification and Cancellation of Outstanding Options. The
Committee  may amend or modify any  option in any manner to the extent  that the
Committee  would have had the authority  under the Plan  initially to grant such
Option;  provided that no such amendment or modification shall impair the rights
of any  Participant  under any Option  without the consent of such  Participant.
With the Participant's  consent, the Committee may cancel any Option and issue a
new Option to such Participant.

        17. Indemnification. In addition to such other rights of indemnification
as they may have as members of the Board or the  Committee,  the  members of the
Committee  shall be  indemnified  by the Company  against all costs and expenses
reasonably incurred by them in connection with any action, suit or proceeding to
which they or any of them may be party by reason of any action  taken or failure
to act under or in connection  with the Plan or any Option  granted  thereunder,
and  against all  amounts  paid by them in  settlement  thereof  (provided  such
settlement is approved by independent  legal counsel selected by the Company) or
paid  by  them  in  satisfaction  of a  judgment  in any  such  action,  suit or
proceeding;  provided, however, that any such Committee member shall be entitled
to the  indemnification  rights set forth in this Section 17 only if such member
has acted in good faith and in a manner that such member reasonably  believed to
be in or not opposed to the best  interests 

                                       12

<PAGE>

of the Company and, with respect to any criminal  action or  proceeding,  had no
reasonable cause to believe that such conduct was unlawful, and further provided
that upon the  institution  of any such action,  suit or  proceeding a Committee
member shall give the Company written notice thereof and an opportunity,  at its
own  expense,  to handle  and  defend  the same  before  such  Committee  member
undertakes  to  handle  and  defend  it on his or her  own  behalf.

reasonable  attorneys'  fees and  expenses)  incurred  in  connection  with such
proceeding shall be paid by, and shall be deemed a joint and several  obligation
of, the Depositor.

( "Subscriber").

1. Service and Equipment.
    A. The "Service"  provided in connection  with this Agreement  consists of a
microcircuit  management  system  which  includes  (i) one or more  modules of a
search  system for  accessing a  proprietary  integrated  database (the "TACTech
Database"),  as set forth on  Schedule A annexed  hereto and by its terms made a
part hereof  ("Schedule  A"),  (ii) the software  relating to all such  modules;
(iii)  all  documentation  or user  manuals  relating  to the  TACTech  Database
(collectively the "Documentation"),  and (iv) an authorized copy of a particular
communications  software  program,  in each case as are  provided  by TACTech to
Subscriber under this Agreement.

    B. The "Equipment"  provided in connection  with this Agreement,  other than

Schedule A hereto. Such Equipment, if any, will consist of (i) an IBM PS/2, (ii)
a 2400 band modem, and (iii) a Printer,  all as more  particularly  described in
said Schedule A.

    2.  License.  Subject  to  the  terms  of  this  Agreement,  TACTech  grants
Subscriber  a   non-exclusive,   non-transferable   limited  site  license  (the
"License") to access data (the "Data") using the Service and Equipment,  if any.
Except as otherwise provided herein, Subscriber will have access to the Database
through  Subscriber's own computer  equipment located in Subscriber's  office at
such times as the Database is generally  available for such access.  The License
includes the right to generate printouts of specially  formatted portions of the
Database,  provided,  however,  that other than as required  for  Subscriber  to
effectively  utilize  the  Database,  such  printouts  shall not be  reproduced,
transferred,  transmitted  or  distributed  in any  form or by any  means to any
unaffiliated  third parties by Subscriber  without the prior written  consent of
TACTech.

    3.  Limitation  of  License.  TACTech  represents  that the  Service and the
Database  are the sole  property of TACTech  and are  protected  by  appropriate
copyrights.  Data may be stored in memory, manipulated,  analyzed,  reformatted,
printed and displayed for Subscriber use only.  Subscriber may not redistribute,
reproduce,  transfer or transmit  (except to employees of Subscriber) any of the
specially  formatted  portions of the Data or the Database in any form or by any
means to any third party without TACTech's prior written consent. Subscriber may
use the  Service,  modules and Database  only for its own internal  purposes and
shall not use the Service and/or its individual  components as a component of or
a basis for any materials, reports, database or the like prepared for commercial
sale, access or distribution  outside Subscriber's  organization.  Subscriber is
not permitted to duplicate  components of the service,  or portions thereof,  in
any way  except  that  Subscriber  may  make  archival  copies  of  Subscriber's
individual  search results  generated by the input into the TACTech  Database of
Subscriber's  particular data for backup or support purposes only, provided that
such archival  copies shall contain the same  copyright  notice and  proprietary
markings as appear on the original software.  Specific  restrictions  concerning
Subscriber's use of the Service, or portions thereof, include the following: (1)
Subscriber  is  permitted  under this  Agreement to use the  Equipment,  if any,
provided, however, that Subscriber agrees to take reasonable care in the use and
maintenance  of  such  Equipment;  (2)  Subscriber  may  not  reverse  engineer,
decompile, modify in any way or create derivative works based on the Service, or
any  portion  thereof;  and (3)  portions  of the  TACTech  Database  limited to
individual search results may be copied onto electronic/magnetic media (or other
machine-readable form) solely for temporary use in conjunction with Subscriber's
editing  or  reformatting  of data for  purpose  of  making  a  single  printout
(human-readable copy) thereof.

    4. Rights in the Data.  Except for the License  granted  herein,  all right,
title and  interest in the  Database  and the  specially  formatted  Data in all
languages, formats and media throughout the world, are and shall continue to be,
the exclusive property of TACTech.  Subscriber shall acquire no ownership rights
in or title to the Service, the Equipment (except as otherwise provided herein),
the TACTech Database,  or any portions thereof.  Subscriber's use of the Service
is subject to the disclaimers and restrictions on use contained herein.

    5. Term of Agreement. This Agreement and the license granted hereunder, upon
acceptance  by TACTech,  shall remain in force for a period of one (1) year from
the date of this  Agreement  unless  terminated by either party upon thirty (30)
days prior  written  notice to the other  party.  In  addition  to any rights or
remedies  available to it, TACTech may terminate this Agreement and all licenses
hereunder  if  Subscriber  commits a material  breach of any  provision  of this
Agreement.  This  Agreement,  may, by mutual written  agreement,  be renewed for
successive  one (1) year  periods,  prior to the  expiration of the then current
term  and  subject  to  the  then  current  prices,   provided,   however,  that

provided  herein.   If  TACTech   introduces  new  or  additional   services  or
significantly  modifies  existing  modules  or  services,  TACTech  may charge a
separate or additional fee therefor,  provided  TACTech  notifies  Subscriber of
such separate or  additional  fee.  Such  notification  will be deemed to modify
Schedule A hereto;  provided,  however,  Subscriber  may decline to subscribe to
such new or additional  services in which case Subscriber shall not be obligated
to pay any separate or  additional  fees  thereon.  If TACTech  terminates  this
Agreement or Subscriber's  access to the Database due to no fault of Subscriber,

charges  incurred  on such  password  after  TACTech's  receipt of notice and an
opportunity during regular business hours to terminate the stolen password.

                  Subscriber  a   non-transferable   limited  use  license  (the
                  "License")  to access data (the "Data")  using the Service and
                  Equipment, if any. TACTech agrees that during the term of this
                  Agreement TACTech will not grant to any other party a license,
                  or otherwise  authorize any other party, to have access to the
                  Data using the Service if such other party is in the  business
                  of distributing  electronic  component parts,  except that the
                  foregoing shall not apply to Rochester Electronics for so long
                  as it remains a  distributor  of obsolete or DMS  products for
                  the D.O.D. and its contractors. It is expressly understood and
                  agreed that a party which is in the business of  manufacturing
                  electronic  component  parts and selling  those parts which it
                  manufactures  shall  not be  deemed  a party  which  is in the
                  business of distributing electronic component parts."

3.       The following sentence shall be added as the last sentence of Section
         "3. Limitation of License":

                  "The License does not  authorize  Subscriber to have more than
                  three  simultaneous  users of the Service and only  authorizes
                  use   of   the   Service   by   employees   of    Subscriber's
                  ____________________ Division."

4.       Section "5. Term of Agreement" shall be restated in its entirety as
         follows:

                  "This  Agreement  and  the  license  granted  hereunder,  upon
                  acceptance  by TACTech,  shall remain in force for a period of
                  three  (3)  years  from  the date of this  Agreement,  subject
                  however to earlier termination upon written notice of election
                  to so  terminate  given by either party if (i) the other party
                  commits a material  breach of this Agreement and fails to cure
                  same  within  15 days  of  written  notice  thereof  from  the
                  non-defaulting   party,   or  (ii)  the  other  party  becomes
                  insolvent  or bankrupt or admits in writing its  inability  to
                  pay its debts as they mature,  or makes an assignment  for the
                  benefit of creditors, or ceases to function as a going concern
                  or to conduct its

                  operations in the normal course of business.  This  Agreement,
                  may, by mutual  written  agreement,  be renewed for successive
                  one (1)  year  periods,  prior to the  expiration  of the then
                  current term and subject to the then current prices.  Renewals
                  shall also be subject to  termination as provided  herein.  If
                  TACTech  introduces  new or additional  modules or services or
                  significantly  modifies existing modules or services,  TACTech
                  may charge a separate or  additional  fee  therefor,  provided
                  TACTech  notifies  Subscriber  of such  separate or additional
                  fee.  Such  notification  will be deemed to modify  Schedule A
                  hereto; provided however,  Subscriber may decline to subscribe
                  to such new or  additional  services in which case  Subscriber
                  shall not be obligated to pay any separate or additional  fees
                  thereon and TACTech  shall be free to grant other  parties the
                  right  to  subscribe  to  such  new  or   additional   service
                  regardless of the business in which such party is engaged."

         IN  WITNESS  WHEREOF,  the  undersigned  have  executed  this  Rider to
Agreement on the 19th day of May, 1993.

Jan Salsgiver
President
Zeus Electronics, Inc.

Dear Jan,

         This  letter  will serve to amend and  extend the "Terms of  Agreement"
between Transition Analysis of Component Technology,  Inc. ("TacTech") and Arrow
Electronics,  Inc.  ("Arrow")  dated  as of  May  19,  1993,  with  an  original
expiration  date of May 18, 1996,  together with Rider thereto and Schedule A to
said Rider (collectively, the "Agreement"), as follows:

1. The fee  structure  set forth in Schedule A to the Rider to the  Agreement is
hereby  amended to provide for an annual fee of $200,000 in lieu of the $108,000
annual fee currently provided, payable as per Paragraph 4 of said Schedule A but
at the rate of $16,666.66  per month.  The rate increase is effective as of July
1, 1995.

2. The  termination  date of the  Agreement is extended  from May 18, 1996 until
June 30, 1998 and accordingly, Paragraph 4 of the Rider which restates Paragraph
5 of the Agreement is amended to substitute "July 1, 1995" for "the date of this
Agreement" as therein set forth.

3. TacTech shall  provide to Zeus  Electronics,  Inc. as an  additional  module,
without  additional  cost and upon the same terms as are applicable to the other
modules  and  services  provided  by TacTech  under the  Agreement,  the TacTech
"military to  commercial"  conversion  data module.  TacTech  shall  continually
update the data for this module to reflect ongoing changes to standard  military
specification semiconductors and their commercial equivalents.

4.  Paragraph  1 of Schedule A is amended to provide  that in lieu of  unlimited
usage via a local 1-714 area code telephone number, Zeus Electronics,  Inc. will
be entitled to one thousand  four hundred  (1,400) hours of annual access to the
TacTech  database via a local 1-714 area code telephone  number.  For usage over
1,400 hours per annum,  Zeus  Electronics,  Inc. will pay an  additional  fee of
$80.00 per hour billed on the same terms and  conditions  as per  Paragraph 4 of
Schedule A.



<PAGE>



         In all other respects,  the Agreement is ratified and affirmed.  If the
foregoing  accurately  sets forth our  understanding,  please have an authorized
signatory of Arrow  acknowledge  same beneath the words "Accepted and Agreed to"
at the foot hereof  whereupon  this will  constitute a binding  amendment to the
Agreement.

                                                Very truly yours,
