Item 5.  Other Events.


         (a)      Exchange Agreement

                  Base Ten  Systems,  Inc.  ("Company")  and the  holders of the
Company's   outstanding  Series  A,  Convertible  Preferred  Shares  ("Series  A
Preferred  Stock"),  entered into an Exchange Agreement dated as of December 31,
1998  ("Exchange  Agreement").  Pursuant to the Exchange  Agreement,  all of the
outstanding  shares  of  Series  A  Preferred  Stock  would  be  exchanged  (the
"Exchange")  for an equal  number of shares of Series B,  Convertible  Preferred
Shares ("Series B Preferred Stock").

                  In  connection  with the  Exchange,  the  holders  of Series B
Preferred  Stock would  receive  warrants to purchase  80,000  shares of Class A
Common Stock, at $3.00 per share, for each $1 million of the principal amount of
Series A Preferred Stock held on September 1, 1998 or thereafter  converted at a
conversion  price of $4.00 or more.  The  issuance of  one-half of the  warrants
would  be  effected  by  the  issuance  of  additional   warrants   ("Additional
Warrants").  The  issuance of the balance of the  warrants  would be effected by
modifying certain existing warrants held by the Series A Preferred Stock holders
("Amended  Warrants")  to, among other things,  decrease the exercise price from
$16.25 to $3.00 per share. The Additional  Warrants would expire four years from
the date of issuance and the Amended Warrants would expire on December 15, 2001.
Certain other  existing  warrants  held by the Series A Preferred  Stock holders
would be modified to allow for a  modification  of the exercise price in certain
circumstances.

                  The  consummation  of  the  transactions  contemplated  by the
Exchange  Agreement  is  subject  to the  satisfaction  of  certain  conditions,
including (i) the  conversion by the holder of the Company's  9.01%  Convertible
Subordinated  Debentures  for  2,500,000  shares of Class A Common  Stock or the
execution and delivery to the Company of an effective  irrevocable direction for
such conversion effective upon the Exchange (see paragraph 5(b) below), and (ii)
the effectiveness of a registration  statement covering the resale of the shares
of Class A Common Stock issuable upon conversion of the Series B Preferred Stock
and exercise of the Additional Warrants and the Amended Warrants.

         (b)      9.01% Convertible Subordinated Debentures

                  The holder of the  Company's  9.01%  Convertible  Subordinated
Debentures  executed and delivered to the Company an  irrevocable  consent dated
December 22, 1998  pursuant to which the holder  consented to the  conversion of
the Debentures upon consummation of the Exchange (see paragraph 5(a) above). The
holder also  consented to the  modification  of the  Debentures  to decrease the
conversion  price at which the  Debentures are  convertible  into Class A Common
Stock from $12.50 to $4.00,  as approved by the  Company's  shareholders  at the
Special Meeting held on November 10, 1998,  simultaneous  with the conversion of
the Debentures. An aggregate of 2,500,000 shares of Class A Common Stock will be
issued to the holder upon conversion of the Debentures.

         (c)      Description Of Existing Capital Stock


General.
                  The  authorized  capital  stock  of the  Company  consists  of
60,000,000  shares of Class A Common Stock,  2,000,000  shares of Class B Common
Stock and 994,200.9375  shares of Preferred Stock, all of which have a par value
of $1.00 per share.  As of January 4, 1999,  there were  outstanding  18,659,738
shares of Class A Common Stock,  and 71,410 shares of Class B Common Stock.  The
Company has designated 14,942.17773437 shares of the Preferred Stock as Series A
Preferred  Stock,  all of which were  outstanding as of January 12, 1999. If the
transactions  contemplated by the Exchange  Agreement (see paragraph 5(a) above)
are consummated,  no shares of Series A Preferred Stock would be outstanding and
the Company would designate  14,942.17773437 shares of Preferred Stock as Series
B Preferred Stock.


Common Stock
                  Dividends.  Both  classes of the  Company's  Common Stock have
identical cash and property dividend rights.  Cash or property  dividends can be
declared  and paid on the Class A Common  Stock  and  Class B Common  Stock as a
single class. If a dividend is paid, the same amount shall be paid in respect of
each outstanding share of Class A Common Stock or Class B Common Stock.

                  If at any time a distribution  is to be paid in Class A Common
Stock or Class B Common Stock (a "share  distribution"),  only shares of Class A
Common  Stock may be paid to holders of Class A Common  Stock and only shares of
Class B Common Stock may be paid to holders of Class B Common Stock.  Whenever a
share  distribution  is paid, the same number of shares shall be paid in respect
of each  outstanding  share of Class A Common Stock or Class B Common Stock. The
Company cannot combine or subdivide  shares of either of such classes without at
the same time making a proportionate  combination of shares of the other of such
classes.

                  Voting Rights.  Except for class votes as required by law (and
subject to voting rights that may be granted to any holders of Preferred Stock),
holders of both classes of Common Stock vote or consent as a single class on all
matters,  including the election of directors, with each share of Class A Common
Stock and each share of Class B Common Stock having one vote per share.

                  All directors of the Company previously elected by the holders
of Class A Common Stock as a class and all directors  previously  elected by the
holders of Class B Common Stock as a class are considered as having been elected
by the holders of Class A Common Stock and Class B Common Stock voting together.

                  The holders of Class A Common Stock and Class B Common  Stock,
voting as a single class,  shall be entitled to vote as a separate  class on the
removal,  for cause,  of any  director  (subject to voting  rights of  Preferred
Stock).

                  Conversion.  At the option of the holder of record, each share
of Class B Common Stock is  convertible at any time into 1 1/2 shares of Class A
Common Stock  (subject to adjustment  in the event of a capital  reorganization,
reclassification,  consolidation,  merger or sale of all or substantially all of
the Company's  assets,  as provided in the  Certificate of  Incorporation).  The
Class A Common Stock is not convertible.

                  Other Rights.  Shareholders of the Company's Common Stock have
no  preemptive  or  other  rights  to  subscribe  for  additional   shares.   On
liquidation,  dissolution  or winding up of the  Company,  all  shareholders  of
common stock,  regardless of class,  are entitled to share ratably in any assets
available for distribution. No shares of either class are subject to redemption.
All outstanding shares are fully paid and non-assessable.

                  Transfer Agent. The transfer agent and registrar for shares of
the Class A Common Stock and Class B Common Stock is American  Stock  Transfer &
Trust Company, 40 Wall Street, New York, New York 10005.


Preferred Stock

         General.  The  Company's  Board of  Directors  is  empowered to fix the
designations, powers, preferences and relative, participating, optional or other
special  rights of the Preferred  Stock and the  qualifications,  limitations or
restrictions of those preferences or rights.


         Series A  Preferred  Stock.  As of January  12,  1999,  the Company had
issued  14,942.17773437  shares of Series A Preferred Stock. Holders of Series A
Preferred Stock have the following rights, privileges and preferences:


                  Term;  Dividends  and  Illiquidity  Payments.   The  Series  A
Preferred  Stock mature in December  2000 and pay a cumulative  dividend of 8.0%
per annum  during  any  quarter in which the  closing  bid price for the Class A
Common  Stock  is less  than  $8.00  for any 10  consecutive  trading  days.  An
equivalent payment is payable to any holder of Series A Preferred Stock which is
subject during any quarter to a standstill period (as described below) following
a Company  underwritten  public offering or which is non-convertible  because of
the limitations  described  below.  Such dividends and payments are payable only
prior to  conversion,  and  payable  in cash or  additional  shares  of Series A
Preferred Stock at the Company's option;  however,  if the Company elects to pay
the  dividend in Series A Preferred  Stock,  the amount of such  payment will be
125% of the cash amount due.


                  Liquidation  Preference.  The Series A  Preferred  Stock has a
liquidation preference of $1,000 plus any accrued and unpaid dividends.


                  Conversion Rights. The Series A Preferred Stock is convertible
at any time or from  time to time into  Class A Common  Stock,  at a  conversion
price equal to the lesser of (i) $16.25 per share, or (ii) the Weighted  Average
Price of the Class A Common Stock prior to the conversion date. Weighted Average
Price is defined as the volume weighted average price of Class A Common Stock on
Nasdaq (as reported by Bloomberg Financial Markets) over any two trading days in
the 20 trading day period  ending on the day prior to the date the holder  gives
notice of conversion (excluding the lowest closing bid price in the period). The
holder has the right to select such two days. No more than  3,040,000  shares of
Class A Common  Stock  shall be issued  upon  conversion  of all of the Series A
Preferred Stock,  except for additional  shares of Class A Common Stock issuable
pursuant to  anti-dilution  provisions.  Any Series A Preferred  Stock remaining
outstanding  because of this  limitation may be redeemed at the holder's  option
for a subordinated 8% promissory note maturing when the Series A Preferred Stock
would have matured.


                  Company  Redemption  Right.  The Company has the right, at any
time, to redeem all or any part of the  outstanding  Series A Preferred Stock or
subordinated notes at 130% of their original purchase price.


                  Mandatory Redemption on Maturity. Any Series A Preferred Stock
or  subordinated  notes still  outstanding  in December 2000 must be redeemed in
either cash or at the Company's  option, in Class A Common Stock. If the Company
elects  to make the  redemption  in Class A Common  Stock,  the  amount  of such
payment will be 125% of the original purchase price.


                  Voting  Rights.  The holders of the Series A  Preferred  Stock
have the same voting rights as the holders of Class A Common  Stock,  calculated
as if all outstanding shares of Series A Preferred Stock had been converted into
shares  of  Class A  Common  Stock  on the  record  date  for  determination  of
shareholders  entitled to vote on the matter  presented,  subject to limitations
applicable to certain holders.


                  Warrants.  For each $1 million of the Series A Preferred Stock
purchased,  the purchaser received warrants to purchase 40,000 shares of Class A
Common Stock exercisable at $16.25 per share.


                  Right  of First  Refusal.  So long as the  Series A  Preferred
Stock remains  outstanding,  each holder has the right (with certain exceptions)
to  purchase,  on five days  notice,  up to that  portion of any  future  equity
financing  by the  Company  which  would be  sufficient  to enable the holder to
maintain its  percentage  interest in the  Company's  equity on a fully  diluted
basis.


                  Five Percent Limitation. The holders of the Series A Preferred
Stock  are not  entitled  to  receive  shares  of  Class A Common  Stock  upon a
conversion  to the  extent  that the sum of (i) the  number of shares of Class A
Common Stock beneficially  owned by the holder and its affiliates  (exclusive of
shares of Class A Common  Stock  issuable  upon  conversion  of the  unconverted
portion  of the  Series A  Preferred  Stock and  shares of Class A Common  Stock
issuable upon conversion or exercise of any other securities of the Company) and
(ii) the number of shares of Class A Common Stock  issuable  upon  conversion of
the Series A Preferred  Stock then being  converted,  would result in beneficial
ownership by the holder and its affiliates of more than 4.9% of the  outstanding
Class A Common Stock.


                  Registration.  The Company granted the holders of the Series A
Preferred Stock mandatory  registration rights with respect to the resale of the
shares  of  Class A  Common  Stock  underlying  the  Series  A  Preferred  Stock
(including  any Series A Preferred  Stock which may be issued as a dividend) and
the shares of Class A Common Stock underlying the warrants issued to the holders
of the Series A Preferred  Stock.  The  holders of the Series A Preferred  Stock
have  agreed,  if requested by a managing  underwriter,  to a 90-day  standstill
period  following any  underwritten  Company public offering during which period
the holders may not sell the Class A Common Stock  underlying  both the Series A
Preferred Stock and the warrants issued to the holders, but not in excess of two
such  standstills in any 18-month  period.  In the event a standstill  period is
effective,  the maturity date of the Series A Preferred  Stock would be extended
by the duration of the standstill period.


         Series B  Preferred  Stock.  If the  transactions  contemplated  by the
Exchange  Agreement (see paragraph 5(a) above) are consummated,  all outstanding
shares of Series A Preferred  Stock would be  exchanged  for an equal  number of
shares of Series B Preferred  Stock.  The terms of the Series B Preferred  Stock
would be identical to the terms of the Series A Preferred Stock,  except for the
following differences:


                  Term.  The Series B Preferred  Stock would  mature on December
15, 2000.


                  Mandatory Redemption on Maturity. Any Series B Preferred Stock
still outstanding after December 15, 2000 would be redeemed in either cash or at
the Company's option, in Class A Common Stock. If the Company elects to make the
redemption in Class A Common Stock,  the amount of such payment would be 125% of
the original purchase price.


                  Dividends and  Illiquidity  Payments.  The holders of Series B
Preferred  Stock would be entitled to receive  dividends when and if declared by
the Board of Directors,  out of funds legally available therefor. The holders of
Series B Preferred  Stock would be entitled to  participate  with the holders of
the Class A Common  Stock so that the holders of Series B Preferred  Stock would
receive with  respect to each share of Series B Preferred  Stock an amount equal
to (x) the  dividend  payable with respect to each share of Class A Common Stock
multiplied  by (y) the number of shares of Class A Common  Stock into which each
share of Series B Preferred  Stock is convertible as of the record date for such
dividend. A payment of 8.0% per annum would be payable to any holder of Series B
Preferred  Stock  which is subject  during any  quarter to a  standstill  period
following a Company  underwritten  public  offering or which is  non-convertible
because of the limitations  described below.  Such payment would be payable only
prior to conversion,  and payable in cash or additional Series B Preferred Stock
at the Company's option;  however,  if the Company elects to pay the dividend in
Series B Preferred  Stock,  the amount of such payment would be 125% of the cash
amount due.


                  Liquidation  Preference.  The Series B  Preferred  Stock would
have a liquidation  preference as to principal amount and any accrued and unpaid
dividends.


                  Conversion  Rights.  The  Series B  Preferred  Stock  would be
convertible  at any time or from time to time into  Class A Common  Stock,  at a
conversion price equal to $4.00.


                  Company Redemption Right. The Company would have the right, at
any time, to redeem all or any part of the outstanding  Series B Preferred Stock
at 130% of their original purchase price.


                  Warrants.  For each $1 million of the Series A Preferred Stock
outstanding on September 1, 1998 and thereafter  converted at a conversion price
of $4.00  or more,  the  holders  of  Series B  Preferred  Stock  would  receive
four-year warrants to purchase 80,000 shares of Class A Common Stock exercisable
at $3.00 per share.  The issuance of one-half of the warrants  would be effected
by  modifying  certain  provisions  of  existing  warrants  held by the Series A
Preferred Stock holders.  The Company may force the exercise of the warrants if,
among  other  things,  the Class A Common  Stock  trades at $4.00 or more for 20
consecutive  trading days and the aggregate of cash (and cash  equivalents)  as
shown on the Company's most recent balance sheet is $5,000,000 or more. If there
is a forced exercise, the exercise price of certain other existing warrants held
by the Series B Preferred Stock  holders  would be modified to the lesser of (i)
market value and (ii) the exercise price then in effect.
