                                  Schedule 13D


Item 1.   Security and Issuer.

          This statement  relates to shares of the common stock, par value $.002
          per share ("Common Stock"),  of Marine Management  Systems,  Inc. (the
          "Company"),  which  are  issuable  upon  conversion  of the  Company's
          Five-Year Senior  Convertible Note (the  "Convertible  Note"),  in the
          principal amount of $400,000, purchased by the reporting persons.

          The Convertible  Note is convertible,  at the rate of $1.00 face value
          of the  Convertible  Note for each share of Common Stock,  by Reliable
          Credit  Association  Profit  Sharing  Plan,  Account  #97305370  up to
          400,000 shares of the Common Stock (the "Conversion Shares"),  subject
          to adjustments under certain circumstances,  at any time and from time
          to time (i) after  December 10, 1998,  except sooner in the event that
          the Company shall  consolidate with or merge into another  corporation
          before such date,  and (ii) prior to March 31, 2003 or upon receipt of
          payment in full of the principal  amount of the  Convertible  Note and
          accrued interest thereon,  whichever is earlier.  For purposes of this
          Schedule 13D,  such  Conversion  Shares are deemed to be  beneficially
          owned by Reliable  Credit  Association  Profit  Sharing Plan,  Account
          #97305370.

          The Convertible  Note entitles its holder,  prior to conversion of the
          Convertible  Note, to vote that number of  Conversion  Shares to which
          the Convertible  Note is convertible on the record date for such vote,
          with  respect to all  matters  voted on by  holders  of the  Company's
          Common Stock voting together as a single class.

          The principal executive offices of the Company are located at 470 West
          Avenue, Stamford, Connecticut 06902.

          This Schedule 13D is being filed by Reliable Credit Association Profit
          Sharing Plan,  Account  #97305370 (the "Plan") and its  Administrator,
          Irwin B. Holzman:

               #97305370

          (b)  c/o May Management,  Inc.,  4550 Kruse Way #345, Lake Oswego,  OR
               97035

          (c)  An employee  Profit Sharing Plan organized  under the laws of the
               State of Oregon.

          (d)  During the last five (5) years,  the Plan has not been  convicted
               in any criminal proceeding.

          (e)  During the last five (5) years,  the Plan has not been a party to
               a  civil  proceeding  of a  judicial  or  administrative  body of
               competent  jurisdiction,  as a result of which proceeding  having
               become  subject to a judgment,  decree or final  order  enjoining
               future  violations  of, or  prohibiting  or mandating  activities
               subject  to,  federal or state  securities  laws or  finding  any
               violation with respect to such laws.

Item 3.   Source and Amount of Funds or Other Consideration.

          The funds, in the aggregate amount of $400,000, used in purchasing the
          Convertible  Note on July 10, 1998  originated from pension funds held
          in an employee  profit  sharing plan held in trust and invested in the
          ordinary course of the Plan's operations.

Item 4.   Purpose of Transaction.

          The Plan acquired the  Convertible  Note in a private  transaction for
          investment  purposes.  The purpose of the Plan  obtaining the right to
          vote the  Conversion  Shares,  prior to conversion of the  Convertible
          Note,  is to enable the Plan to influence  the outcome of matters that
          are subject to a vote of stockholders  of the Company.  Depending upon
          market conditions and other factors that the Plan may deem material to
          its investment decision,  the Plan may purchase additional  securities
          of the Company in the open market or in private  transactions,  or may
          dispose of all or a portion of the  securities  of the Company that it
          now owns or hereafter may acquire.


                                       -4-


<PAGE>



          The  Company  also has  granted  to the  holders of  five-year  senior
          convertible  notes  acquired  on July  10,  1998,  of  which  the Plan
          constitutes 20% (collectively,  "Purchasers"),  the right to appoint a
          seventh  (7th)  member  to the  Company's  six  (6)  member  board  of
          directors.  Notwithstanding any such appointment,  the Purchasers were
          given the option to  designate an observer to the  Company's  board of
          directors.

          The Company  also has granted to such  Purchasers  certain  preemptive
          rights to preserve their respective Equity Percentage  (defined herein
          below),  pursuant to which the Purchasers may purchase,  upon the same
          terms and conditions,  that amount of any additional  shares of Common
          Stock or  security  convertible  into  shares of  Common  Stock or any
          rights or options to  purchase  shares of Common  Stock  issued by the
          Company  for  consideration  that  includes  cash  and not to  selling
          stockholders  of the  Company  pursuant  to a  merger  or  acquisition
          transaction.  For  purposes of the  transaction,  "Equity  Percentage"
          means that percentage equal to (1) the Conversion Shares (after giving
          effect to any  adjustments)  divided by (2) the  Company's  issued and
          outstanding  Common Stock, on a fully diluted basis  (inclusive of all
          outstanding  securities  of the  Company  convertible  into  shares of
          Common Stock and rights or options to purchase shares of the Company's
          Common Stock).

          Except as set forth in this Item 4, the Plan does not have any present
          plans or  proposals  that relate to or that would result in any of the
          actions  specified  in clauses  (a)  through (j) of Item 4 of Schedule
          13D.

Item 5.   Interest in Securities of the Issuer.

          (a)  The  calculations in this Item are based upon 4,421,120 shares of
               Common  Stock  issued and  outstanding  as of June 9, 1998 (based
               upon the Company's  Proxy  Statement  dated as of such date filed
               with  the  Securities  and  Exchange  Commission).  For  purposes
               hereof,  the Plan  beneficially owns 400,000  Conversion  Shares,
               issuable upon exercise of the Convertible Note,


                                       -5-


<PAGE>



               comprising  9.05% of the  issued  and  outstanding  shares of the
               Company's  Common  Stock.  The  foregoing   calculation  is  made
               pursuant to Rule 13d-3 promulgated under the Securities  Exchange
               Act of 1934.

          (b)  The Plan is the sole owner of the Convertible Note and, under the
               terms of such  Convertible  Note,  has the sole power to vote its
               Conversion  Shares  prior to any  conversion  of the  Convertible
               Note,  based  upon a 1:1  exchange  of  votes  to the  number  of
               Conversion  Shares into which the Convertible Note is convertible
               at the time of such vote).  Upon the exercise of the  Convertible
               Note,  the Plan will also have the sole power to vote and dispose
               of all of the underlying Conversion Shares.

          (c)  The Plan has not  effected  any  transactions  in  shares  of the
               Company's  Common Stock or in any options or warrants to purchase
               such Common Stock in the past 60 days.

          (d)  The Plan affirms that no other person has the right to receive or
               the  power to  direct  the  receipt  of  dividends  from,  or the
               proceeds  from the sale of,  the shares of the  Company's  Common
               Stock beneficially owned by U.S. Bank.

          (e)  It is  inapplicable  for the purposes herein to state the date on
               which the Plan  ceased to be the owner of more than five  percent
               (5%) of the Shares.

Item 6.   Contracts, Arrangements, Understandings or Relationships with  Respect
          to Securities of the Issuer.

          Except as set  forth in Item 4, the Plan  does not have any  contract,
          arrangement,  understanding or relationship  (legal or otherwise) with
          any person with respect to any securities of the Company.  As noted in
          Item 4,  the  Company  granted  the  Plan  (i) the  right  to vote its
          Conversion  Shares and (ii), in conjunction with the other Purchasers,
          the right to appoint the seventh (7th) of the Company's six (6) member
          board of directors and

                         SENIOR NOTE PURCHASE AGREEMENT


     THIS SENIOR NOTE PURCHASE AGREEMENT  ("Agreement") is made and entered into
this 10th day of July, 1998 by and between MARINE  MANAGEMENT  SYSTEMS,  INC., a
Delaware  corporation  (the "Company"),  and the purchasers  listed on Exhibit A
annexed hereto (the "Purchasers" and individually, a "Purchaser").

                                R E C I T A L S:

     A. The Company desires to obtain  financing by issuance of Senior Five-Year
Convertible Notes (the "Notes") which are the subject of this Agreement; and

     B. The  Purchasers  desire to acquire the Notes on the terms and conditions
set forth herein.

                               A G R E E M E N T:

                    NOW, THEREFORE, IT IS AGREED as follows:

     1. PURCHASE OF SENIOR NOTES.

          1.1 Subject to the terms and conditions  hereof, the Purchasers hereby
     agree to purchase from the Company,  and the Company has offered and hereby
     agrees to issue and sell to the Purchaser  $2,000,000  aggregate  principal
     amount of the Notes due June 30, 2003,  to be issued  substantially  in the
     form attached hereto as Exhibit B for delivery at the respective offices of
     the Purchasers,  against  payment to the Company of the respective  amounts
     set forth opposite the  Purchasers'  names in Exhibit A by wire transfer in
     same day or next day funds.  The term "Notes" as used herein shall  include
     the Notes  originally  issued  pursuant to the provisions of this Agreement
     and any promissory  notes delivered in  substitution or exchange  therefor.
     The Notes will bear  interest,  be payable and mature at the time and under
     the terms and conditions  specified therein.  The Notes will be convertible
     into shares of the  Company's  Common Stock at the rate of $1.00 face value
     of the Note for  each  share of the  Company's  Common  Stock,  subject  to
     adjustment, all as provided in the Notes.

The Company has authorized  and reserved for issuance up to 2,000,000  shares of
Common  Stock  (which  number may be  adjusted  as  provided  in the Notes) upon
conversion  of the Notes in  accordance  with their terms (as used  herein,  the
"Notes" and the shares of the Common Stock issuable upon conversion  thereof are
referred to collectively as the "Securities").


<PAGE>


          1.2 The purchase price for the Notes to be purchased by the Purchasers
     hereunder shall be an aggregate of $2,000,000 (the "Purchase  Price").  The
     Purchasers  shall pay the Purchase  Price by wire  transfer of  immediately
     available  funds to the  Company.  Simultaneously  against  receipt  by the
     Company of the Purchase  Price,  the Company shall deliver one or more duly
     authorized,  issued and executed  Notes  (I/N/O each  Purchaser or , if the
     Company  otherwise  has been  notified,  I/N/O such  Purchaser's  nominee).
     Notwithstanding the foregoing,  in the event that any Purchaser is a holder
     of the  Senior  Convertible  Notes  issued on April 8,  1998  (the  "Bridge
     Notes") pursuant to the Bridge Note Purchase  Agreement dated April 8, 1998
     (the "Bridge Note  Agreement"),  such  Purchaser  shall present such Bridge
     Notes for  cancellation,  in which case the entire  amount of principal and
     accrued interest  outstanding  under such Bridge Notes shall be deemed paid
     to the Company and shall be  credited  against the portion of the  Purchase

     material adverse effect on the business,  properties,  prospects, condition
     (financial  or otherwise) or results of operations of the Company or on the
     consummation of any of the  transactions  contemplated by this Agreement (a
     "Material  Adverse  Effect").  The  Company  has full power and  authority,

     borrow hereunder,  and to make, execute and deliver the various instruments
     and documents provided for herein.

          2.2 The  execution,  delivery and  performance  by the Company of this
     Agreement  and the Notes,  and the making,  execution  and  delivery by the
     Company of the instruments  contemplated  hereby, have been duly authorized
     by all  necessary  corporate  action and will not violate any  provision of
     law,  court order or decree,  or of its  Certificate  of  Incorporation  or
     Bylaws,  or result in the  breach of, or  constitute  a default  under,  or
     result in the creation of any lien, charge or encumbrance upon any property
     or assets of the Company  pursuant to any  agreement or instrument to which
     it is a party,  or by which it or its  property  may be bound or  affected,
     except as contemplated  hereby or thereby.  Each of this Agreement and each
     Note is a valid and  binding  obligation  of the  Company,  enforceable  in
     accordance with its respective terms.

     Stock for a consideration of less than $1.00 per share of Common Stock.

          2.5 The  Company  has  furnished  the  Purchasers  with  copies of the

          2.6 Except as disclosed in the  Commission  Filings,  the Company does
     not own or  control,  directly  or  indirectly,  any  interest in any other

     where the  failure  to  receive  such  licenses  or  approvals  would  not,
     individually  or in the  aggregate,  have a material  adverse effect on the
     financial  condition,  operations,  business,  assets or  properties of the
     Company.

          2.11 The  minute  books of the  Company  have been  properly  kept and

     Exchange  Commission  ("SEC")  when filed  contained  a  misstatement  of a
     material  fact or omitted to state a material  fact  necessary  to make the
     statements  contained  therein,  in the light of the circumstances in which
     they were made or omitted, not misleading.

     Commission  thereunder  and  (ii)  the  registration  and/or  qualification
     provisions of all applicable  state  securities and "blue sky" laws.  Other
     than pursuant to an effective  registration  statement under the Securities
     Act, the Company has not issued, offered or sold any shares of Common Stock
     (including  for this purpose any  securities of the same or a similar class
     as the Common Stock, or any securities  convertible into or exchangeable or
     exercisable for the Common Stock or any such other  securities)  within the
     six-month period next preceding the date hereof, except as disclosed in the
     Commission  Filings or as set forth on Schedule 2.20 attached  hereto,  and
     the Company shall not directly or indirectly take, and shall not permit any
     of its  directors,  officers or Affiliates  directly or indirectly to take,
     any action  (including,  without  limitation,  any  offering or sale to any
     other  person  or entity of the  shares  of  Common  Stock),  so as to make
     unavailable  the exemption from  Securities Act  registration  being relied
     upon by the Company for the offer and sale to the  Purchasers  of the Notes
     and the  shares  of  Common  Stock  issuable  upon  conversion  thereof  as
     contemplated by this Agreement.

          2.21  Set  forth  on  Schedule  2.21  is a list of all  Related  Party
     Indebtedness and, except for a $15,000  promissory note owed to Mark Story,
     such  Related  Party  Indebtedness  is no longer  outstanding  and has been
     exchanged for shares of Series A

                                       -6-

 

<PAGE>


     Preferred  Stock based on $1,000 in principal  amount and accrued  interest
     for each $1,000 in liquidation  preference of the Series A Preferred Stock.
     The Company has no liability to any entity in respect of such Related Party
     Indebtedness  which has been  exchanged for Series A Preferred  Stock.  The
     shares of Series A Preferred  Stock have been duly authorized and have been
     validly issued,  fully paid and non-assessable.  The shares of Common Stock
     initially  issuable upon  conversion  of the Series A Preferred  Stock have

     been duly reserved for issuance upon such conversion and, when issued, will
     be validly issued, fully paid and nonassessable.

     3.  REPRESENTATIONS  OF THE  PURCHASERS.  This  Agreement is made with each
Purchaser by the Company in reliance upon each  Purchaser's  representations  to
the  Company,  which  by each  Purchaser's  acceptance  hereof,  each  Purchaser
confirms,  that (a)  Purchaser is acquiring the Note to be delivered for its own
account and not for the beneficial  interest of any other person, and not with a
view to the distribution  thereof, and that Purchaser will not distribute,  sell
or  otherwise  dispose of the Note or any of the  shares of Common  Stock of the
Company  issuable  upon  conversion  of the Note except as  permitted  under the
Securities  Act  of  1933,  as  amended  (the  "Act"),  the  General  Rules  and
Regulations   thereunder,   and  all  applicable  State  "Blue  Sky"  laws;  (b)
Purchaser's financial circumstances are such as to permit Purchaser to make this
investment  without  having  a  present  intention  or  need  to  liquidate  its
investment;  (c) Purchaser  severally  confirms further that it has been advised
that neither the Note nor the Common Stock issuable upon the conversion  thereof
have been registered under the Act, and that, accordingly,  such Note and shares
of Common Stock will be what is commonly known as "restricted  securities,"  and
are not freely  transferrable  by Purchaser except pursuant to an exemption from
registration  under the Act,  such as Rule 144, the  substance of which has been
explained to Purchaser or upon  registration  of the Common Stock under the Act;
(d)  Purchaser  is an  "accredited  investor"  as that  term is  defined  in SEC

financial condition and to have access to any and all information  regarding the
Company that Purchaser deems necessary to its decision to purchase the Note, and
(f) that the  following  legends  shall be  placed on the Note  (and,  until the
Common Stock is  registered  under the Act, any Shares of Common Stock  issuable
upon conversion thereof):

               "THE SECURITIES REPRESENTED BY THIS NOTE HAVE
               BEEN ACQUIRED FOR INVESTMENT IN A TRANSACTION

               CONNECTION  WITH  THE  DISTRIBUTION  THEREOF.
               NEITHER THIS NOTE NOR THE  SECURITIES  ISSUED
               UPON  CONVERSION  HEREOF MAY BE  OFFERED  FOR
               SALE OR SOLD OR OTHERWISE  DISPOSED OF EXCEPT
               UPON COMPLIANCE WITH SAID ACT."

     4. CERTAIN COVENANTS BY THE COMPANY

     5. TRANSFER BY THE PURCHASER.

     Neither  the Notes to be  purchased  by the  Purchasers,  nor any  interest
therein, shall be sold, transferred,  assigned, or otherwise disposed of, unless

in federal  securities law, to the effect that registration under the Act is not

     qualified  or to become  licensed as a  securities  broker or dealer in any
     jurisdiction;   (iii)  provide  Purchasers  with  a  reasonable  number  of

     by the indemnified party or any director, officer or controlling person, as
     defined above, in connection with investigating or defending any such loss.

          (b) Promptly after receipt by an indemnified  party under this Section
     6.4 of notice of commencement of any action, the indemnified party will, if
     a claim in respect  thereof is to be made  against any  indemnifying  party
     under this Section 6.4, notify the  indemnifying  party of the commencement
     thereof;  but the  omission  so to notify the  indemnifying  party will not
     relieve it from any liability to any indemnified party except to the extent
     that  the  failure  to  so  notify  such  party   adversely   affected  the
     indemnifying  party.  In case  any  such  action  is  brought  against  any
     indemnified   party  and  it  notifies  the   indemnifying   party  of  the
     commencement  thereof,  the latter will be entitled to participate therein,
     and to the extent desired, jointly, with any other indemnifying party

                                      -10-

     similarly notified,  assume the defense and control the settlement thereof,
     with counsel  reasonably  satisfactory  to such  indemnified  party.  After
     notice  from the  indemnifying  party to such  indemnified  party as to its
     election so to assume the defense thereof,  the indemnifying party will not
     be liable to such indemnified party under this Section 6.4 for any legal or
     other  expenses   subsequently   incurred  by  such  indemnified  party  in
     connection  with  the  defense  thereof,  other  than  reasonable  cost  of
     investigation.

          (c) The  Company  and each  Purchaser  each  have the  right to make a
     reasonable  investigation of the information  contained in any registration
     statement  covered by this  Section 6 to  confirm  its  accuracy,  subject,
     however,  to the obligation of the party making such  investigation to keep
     in confidence any information derived until such time as the information is
     filed with the SEC.

          6.5 To the extent transfers of the Notes or Common Stock are permitted
     pursuant to Section 5 hereof,  Purchaser may transfer,  assign or otherwise
     dispose of its rights under this  Section 6, as a whole or in part,  but no
     such action by a Purchaser shall increase or otherwise affect the nature or
     extent of the Company's obligations provided in this Section.

     7. OTHER AGREEMENTS.

          7.1 Board  Representation.  The Purchasers and their  successors  will
     have the right to designate a nominee,  reasonably  acceptable to the Board
     of Directors of the Corporation,  for election,  at its option, as a member
     of the Board of Directors of the Company, and the Company will use its best
     efforts to cause such  nominee to be elected and  continued  in office as a
     director of the Company until  seventy-five  (75%) percent of the aggregate
     initial  principal  amount of the Notes has been paid, or 75% of the Common
     Stock  received upon  conversion  of the entire  principal of the Notes has
     been sold.  Notwithstanding  the foregoing,  the Purchasers  shall have the
     option to designate  an observer to the Board of  Directors  subject to the
     foregoing conditions. Following the election of such nominee as a director,
     such  person  shall  receive no more or less  compensation  than is paid to
     other  non-officer  directors of the Company for  attendance at meetings of
     the Board of  Directors  of the  Company  and shall be  entitled to receive
     reimbursement  for all reasonable costs incurred in attending such meetings
     including,  but not limited to, food,  lodging and  transportation,  to the
     extent  Directors  are so  reimbursed  generally.  The  Company  agrees  to
     indemnify and hold such director  harmless,  to the maximum extent provided
     to  other  directors  under  the  Corporation's   Restated  Certificate  of
     Incorporation  against any and all claims,  actions,  awards and  judgments
     arising out of his

                                      -11-
 

<PAGE>


     service as a director  and, in the event the Company  maintains a liability
     insurance  policy  affording  coverage  for the  acts of its  officers  and
     directors,  to include such director as an insured  under such policy.  The
     rights  and  benefits  of such  indemnification  and the  benefits  of such
     insurance shall, to the extent possible,  extend to each Purchaser  insofar
     as it may be or may be alleged to be responsible for such director.

          7.2 Preemptive Rights.

          (a) The  percentage of the  Company's  issued and  outstanding  Common
     Stock,  on a  fully-diluted  basis (based on the number of shares of Common
     Stock  outstanding  on the date hereof and any other Equity  Securities (as
     defined below)  outstanding on the date hereof),  represented by the shares
     of Common Stock  issuable upon  conversion  of the Notes in their  entirety
     (after giving effect to any adjustment to the Conversion Price as set forth
     in the Notes),  shall be referred to herein as the "Equity  Percentage." In
     addition  to the  anti-dilution  provision  set  forth  in the  Notes,  the
     Purchasers  shall be entitled to  preemptive  rights as set forth herein in
     order to preserve  such Equity  Percentage.  In the case of the issuance of
     additional  shares of Common Stock or any security that is convertible into
     shares of Common  Stock or any  rights or  options  to  purchase  shares of
     Common  Stock  (collectively,  "Equity  Securities")  which are  issued for
     consideration  that  includes  cash  and  are  not  issued  to the  selling
     shareholders in a merger or acquisition  transaction,  the Purchasers shall
     be  entitled to purchase  such amount of Equity  Securities,  upon the same
     terms and  conditions as applicable to any other  purchaser or recipient of
     such  Equity  Securities,  in an amount so as to preserve  the  Purchasers'
     Equity Percentage.

          (b) For purposes of this Section 7.2, (i) the Company  shall be deemed
     to have issued the  maximum  number of shares of Common  Stock  deliverable
     upon the exercise of any such rights or options or upon  conversion  of any
     such securities and (ii) the  consideration  therefor shall be deemed to be
     the  sum  of  (x)  the  consideration  received  by the  Company  for  such
     convertible  securities or for such other rights or options as the case may
     be, without  deducting  therefrom any expenses or  commissions  incurred or
     paid by the Company for any  underwriting  or issuance of such  convertible
     security  or right or  option,  plus (y) the  consideration  or  adjustment
     payment to be received by the Company in connection  with such  conversion,
     plus (z) the  minimum  price at which  shares  of  Common  Stock  are to be
     delivered  upon the  exercise of such rights or options,  or, if no minimum
     price is specified  and such shares are to be delivered at the option price
     related to the market value of the subject shares,  an option price bearing
     the same  relation to the market  value of the  subject  shares at the time
     such rights or options were granted,  provided that as to such options such
     further

                                      -12-


<PAGE>


     adjustment as shall be necessary on the basis of the actual option price at
     the time of exercise  shall be made at such time if the actual option price
     is less than the aforesaid assumed option price.

          (c) The number of shares of Common Stock at any time outstanding shall
     include  (i) all  outstanding  common  stock of the  Company,  and (ii) the
     aggregate  number of  shares  deliverable  in  respect  of the  convertible
     securities,  rights and options  referred to in this Section 7.2,  provided
     that,  to  the  extent  that  any  such  options,  warrants  or  conversion
     privileges are not exercised, such shares shall be deemed to be outstanding
     only  until the  expiration  dates of the  rights,  options  or  conversion
     privilege or the prior cancellation thereof. Notwithstanding the foregoing,
     there shall not be taken into account,  for the purpose of any  computation
     made pursuant to Section 7.2,  whether for the  determination of the number
     of shares of Common Stock issued or outstanding on or prior to any date, or
     otherwise,  any options,  warrants,  or rights to purchase shares of Common
     Stock of the Company in existence on the date of issuance of the Notes.

     8. CLOSING DATE.

     The date and time of the  issuance  and  sale of the  Notes  (the  "Closing
Date") shall be the date hereof or such other as such be mutually agreed upon in
writing.  Notwithstanding anything to the contrary contained herein, the closing
shall be subject to the conditions set forth in Sections 9 and 10.

     9. CONDITIONS TO THE COMPANY'S OBLIGATIONS.

     such  accuracy  shall  be  measured  as of  such  specified  date)  and the
     performance  by the  Purchasers  in all material  respects on or before the
     Closing Date of all covenants and agreements of each Purchaser  required to
     be  performed  by it  pursuant to this  Agreement  on or before the Closing
     Date;

                                      -13-

<PAGE>


          (c) There shall not be in effect any law or order, ruling, judgment or
     writ  of  any  court  of  public  or  governmental  authority  restraining,
     enjoining or otherwise prohibiting any of the transactions  contemplated by
     this Agreement.

     10. CONDITIONS TO PURCHASERS' OBLIGATIONS.

          (b)  The  accuracy  on the  Closing  Date of the  representations  and

     such  accuracy  shall  be  measured  as of  such  specified  date)  and the
     performance  by the  Company  in all  material  respects  on or before  the
     Closing Date of all covenants and agreements of the Company  required to be
     performed by it pursuant to this Agreement on or before the Closing Date;

          (c) Purchasers  having received the opinion of counsel for the Company
     referred to in Section 2.8;

          (d) The  Company's  Certificate  of  Incorporation  has  been  validly
     amended to provide for (i) an increase in number of shares of Common  Stock

     11. SURVIVAL; INDEMNIFICATION.

          11.1 The representations, warranties and covenants made by each of the
     Company and the Purchasers in this  Agreement,  the annexes,  schedules and
     exhibits hereto and in each instrument,  agreement and certificate  entered
     into and  delivered by them pursuant to this  Agreement,  shall survive the
     Closing and the consummation of the transactions  contemplated  hereby.  In
     the  event  of a  breach  or  violation  of  any of  such  representations,
     warranties or covenants, the party to whom such representations, warranties
     or  covenants  have been made shall have all rights and  remedies  for such
     breach or violation  available to it under the provisions of this Agreement
     or  otherwise,   whether  at  law  or  in  equity,   irrespective   of  any
     investigation made by or on behalf of such party on or prior to the Closing
     Date.

          11.2 The Company  hereby  agrees to  indemnify  and hold  harmless the
     Purchasers,  its  Affiliates  and  their  respective  officers,  directors,
     partners and members (collectively, the "Purchaser Indemnitees"),  from and
     against  any  and  all  losses,  claims,  damages,  judgments,   penalties,
     liabilities  and  deficiencies  (collectively,  "Losses"),  and  agrees  to
     reimburse  the  Purchaser   Indemnitees  for  all  out-of-pocket   expenses
     (including the reasonable fees and expenses of legal counsel), in each case
     promptly as incurred by the Purchaser Indemnitees and to the extent arising
     out of or in connection with:

               (a) any  misrepresentation,  omission of fact or breach of any of
          the  Company's   representations  or  warranties   contained  in  this
          Agreement,   the  annexes,   schedules  or  exhibits   hereto  or  any

          Company pursuant to this Agreement; or

               (b) any failure by the Company to perform in any material respect
          any of its covenants, agreements,

                                      -15-
 

<PAGE>


         undertakings or obligations  set forth in this Agreement,  the annexes,
         schedules  or  exhibits   hereto  or  any   instrument,   agreement  or
         certificate  entered into or delivered by the Company  pursuant to this
         Agreement.

          11.3 Each  Purchaser  hereby agrees to indemnify and hold harmless the
     Company, its Affiliates and their respective officers,  directors, partners
     and members (collectively, the "Company Indemnitees"), from and against any
     and all Losses,  and agrees to reimburse  the Company  Indemnitees  for all
     out-of-pocket expenses (including the reasonable fees and expenses or legal
     counsel),  in each case promptly as incurred by the Company Indemnitees and
     to the extent arising out of or in connection with:

               (a) any misrepresentation,  omission of fact, or breach of any of
          the  Purchasers'  representations  or  warranties  contained  in  this
          Agreement,   the  annexes,   schedules  or  exhibits   hereto  or  any
          instrument,  agreement or certificate entered into or delivered by the
          Purchasers pursuant to this Agreement; or

               (b) any  failure by the  Purchasers  to  perform in any  material
          respect any of its covenants, agreements,  undertakings or obligations
          set  forth  in  this  Agreement  or  any  instrument,  certificate  or
          agreement  entered into or  delivered by a Purchaser  pursuant to this
          Agreement.

          11.4   Promptly   after   receipt  by  either  party  hereto   seeking
     indemnification  pursuant to this  Section 11 (an  "Indemnified  Party") of
     written notice of any investigation,  claim,  proceeding or other action in
     respect of which  indemnification  is being sought (each,  a "Claim"),  the
     Indemnified   Party   promptly   shall   notify  the  party   against  whom
     indemnification   pursuant  to  this   Section  11  is  being  sought  (the
     "Indemnifying  Party") of the commencement  thereof; but the omission to so
     notify the Indemnifying  Party shall not relieve it from any liability that
     it otherwise may have to the Indemnified  Party,  except to the extent that
     the Indemnifying  Party is materially  prejudiced and forfeits  substantive
     rights and defenses by reason of such failure. In connection with any Claim
     as to which  both the  Indemnifying  Party  and the  Indemnified  Party are
     parties,  the  Indemnifying  Party  shall be entitled to assume the defense
     thereof.  Notwithstanding the assumption of the defense of any Claim by the
     Indemnifying  Party,  the Indemnified  Party shall have the right to employ
     separate legal counsel and to participate in the defense of such Claim, and
     the Indemnifying Party shall bear the reasonable fees,  out-of-pocket costs
     and expenses of such  separate  legal counsel to the  Indemnified  Party if
     (and only if):  (x) the  Indemnifying  Party  shall have agreed to pay such
     fees,  out-of-pocket costs and expenses,  (y) the Indemnified Party and the
     Indemnifying  Party reasonably shall have concluded that  representation of
     the

                                      -16-

<PAGE>


     Indemnified  Party and the  Indemnifying  Party by the same  legal  counsel
     would not be  appropriate  due to actual or, as  reasonably  determined  by
     legal counsel to the Indemnified  Party,  potentially  differing  interests
     between  such  parties in the conduct of the  defense of such Claim,  or if
     there may be legal defenses  available to the Indemnified Party that are in
     addition to or disparate from those available to the Indemnifying Party, or
     (z) the  Indemnifying  Party  shall  have  failed to employ  legal  counsel
     reasonably satisfactory to the Indemnified Party within a reasonable period
     of time after notice of the  commencement of such Claim. If the Indemnified
     Party  employs  separate  legal  counsel  in  circumstances  other  than as
     described in clauses (x), (y) or (z) above, the fees, costs and expenses of
     such legal counsel shall be borne  exclusively  by the  Indemnified  Party.
     Except as provided above, the  Indemnifying  Party shall not, in connection
     with  any  Claim  in the  same  jurisdiction,  be  liable  for the fees and
     expenses of more than one firm of legal counsel for the  Indemnified  Party
     (together with appropriate  local counsel).  The  Indemnifying  Party shall
     not,  without the prior  written  consent of the  Indemnified  Party (which
     consent shall not unreasonably be withheld), settle or compromise any Claim
     or  consent  to  the  entry  of any  judgment  that  does  not  include  an
     unconditional  release of the Indemnified  Party from all liabilities  with
     respect to such Claim or judgment.

     12. NOTICES.

     All notices required or permitted to be given hereunder shall be in writing

                        SENIOR FIVE-YEAR CONVERTIBLE NOTE

                                                                   July 10, 1998

     FOR VALUE RECEIVED,  the undersigned,  MARINE MANAGEMENT  SYSTEMS,  INC., a
Delaware   corporation   (the   "Company"),    hereby   promises   to   pay   to
_________________,   (the   "Holder")  or  order,   the   principal   amount  of
_______________  ($___________),  such amount to be due and payable on March 31,
2003.  Interest on the unpaid  principal  balance  from the date hereof shall be
payable  semi-annually  commencing  September 30, 1998 (provided that such first
interest payment date shall be for the period commencing as of the date hereof),
and on each  March 31 and  September  30  thereafter,  at the rate of ten  (10%)
percent  per annum.  For all  interest  payments  through  March 31,  2000,  the
Company, at its option, may elect to pay the interest hereunder by adding to the
outstanding principal amount of this Note, such interest which has not been paid
in cash (the "Additional  Principal Amount").  Interest shall begin to accrue on
such  Additional  Principal  Amount  beginning on and including  the  applicable
interest payment date on which such Additional  Principal Amount is added to the
outstanding principal amount of this Note. If the Company has elected to pay any
such interest  payment  hereunder in Additional  Principal Amount (to the extent
permitted),  it shall so notify the Holder on or before thirty days prior to the
applicable interest payment date. As used herein, the "principal" amount of this
Note at any time shall include the  outstanding  principal  amount of this Note,
including any  Additional  Principal  Amount  outstanding  as of such date.  The
Company  shall have the right to prepay,  without  penalty or premium,  all or a
portion of the principal  amount of this Note with accrued  interest  thereon to
the date of such


<PAGE>


prepayment  upon  thirty  (30)  days'  written  notice to the Holder at any time
following  March 31, 2001.  Any  prepayment  shall be first  applied to interest
thereon  accrued  through  the  prepayment  date and  allocated  among  the then
outstanding  Notes pro rata on the  basis of the then  unpaid  principal  amount
(including any Additional Principal Amount) of each of such Notes. No prepayment
may be permitted  unless,  at the time of such  prepayment,  there is registered
with the  Commission  for sale by the  Holder,  shares  of  Common  Stock of the
Company reflecting full conversion of this Note. The Holder shall be entitled to
convert this Note at any time prior to such Prepayment Date.

     Payments of  principal  and  interest  shall be made in lawful money of the
United States of America at the principal  office of the Holder or at such other
place as the Holder hereof shall have designated to the Company in writing.

     This Note is made  pursuant  to a certain  Senior Note  Purchase  Agreement
dated July 10,  1998 (the  "Agreement")  between the Company and the Holder (and
the other  Holders  named  therein),  and the Holder  hereof is  entitled to the
benefits of the Agreement and may exercise the remedies  provided for thereby or
otherwise  available in respect thereof,  in case of any material breach thereof
by the Company.  (This Note and other Notes  identical in terms (except for name
and face  amount)  issued to Holder and to other  Holders who are parties to the
Agreement,  are  hereinafter  collectively  called  the  "Notes".)  Payments  of
principal  and interest in respect of the Notes are senior to and prior in right
of payment to all other indebtedness for borrowed money of the Company, provided
that  they  shall  be pari  passu  with any  borrowings  by the  Company  from a
recognized  financial  institution for working capital in a principal amount not
to exceed  $500,000;  provided  further that such borrowings for working capital
may be secured by the assets of the Company pursuant to a security agreement and
on terms and conditions reasonably acceptable to the Holder (the "Permitted Bank
Line"). In case of an Event of Default, as defined herein, the unpaid balance of
the  principal  of this Note may be  declared  and become due and payable in the
manner provided herein.

     This  Note  is  issued  subject  to  the  following  additional  terms  and
conditions:

     1. Interest and Payment.

          1.1 The principal  amount of this Note  outstanding  from time to time
     shall bear simple  interest  at an annual  rate of ten  percent  (10%) (the
     "Note Rate") from the date hereof  (provided  that interest shall accrue on
     any Additional  Principal  Amount beginning on and including the applicable
     interest payment date on which such Additional Principal Amount is added to
     the outstanding principal amount of this Note) until payment in full of all
     amounts of principal and interest outstanding under this Note.


                                       -2-

<PAGE>


          1.2 In the event of  conversion  of all or any  portion  of this Note,
     interest  on this  Note  shall  continue  to accrue  until  the  applicable
     conversion date.

          1.3 All  payments  made by the  Company  on this Note shall be applied
     first to the  payment of accrued  unpaid  interest on this Note and then to
     the reduction of the unpaid principal balance of this Note.

          1.4 If  payment  of the  outstanding  principal  amount  of any  Note,
     together with accrued unpaid interest thereon,  is not made on the earliest
     to occur of (i) March 31,  2003;  and (ii) any date on which any  principal
     amount of, or accrued  unpaid  interest  on, any Note is declared to be, or
     becomes,  due and payable pursuant to the terms of such Note prior to March
     31, 2003,  then interest shall accrue on the outstanding  principal  amount
     due under this Note and,  to the  extent  permitted  by law,  on any unpaid
     accrued  interest  due on this Note from and after  such date of default to
     the date of the payment in full of such amounts  (including  from and after
     the date of the  entry of  judgment  in favor of  Holder  in an  action  to
     collect  this Note) at an annual rate equal to the maximum rate of interest
     permitted by applicable law (the "Maximum Rate").

          1.5 In the event  that a court of  competent  jurisdiction  determines
     that such  amounts  paid or agreed to be paid by the Company in  connection
     with this Note causes the  effective  interest  rate on this Note to exceed
     the Maximum Rate, such interest or other  consideration shall automatically
     be reduced to a rate which results in an effective interest rate under this
     Note equal to the Maximum  Rate over the term  hereof,  and, in such event,
     any amounts  received by Holder  deemed to  constitute  excessive  interest
     shall be applied  first to the payment of accrued  unpaid  interest on this
     Note and then to the  reduction  of the  unpaid  principal  balance of this
     Note.

          1.6 In the event that the date for the  payment of any amount  payable
     under this Note falls due on a Saturday, Sunday or public holiday under the
     laws of the State of New York, the time for payment of such amount shall be
     extended to the next succeeding business day and interest shall continue to
     accrue on any  principal  amount so effected  until the payment  thereof on
     such extended due date.

     2. Conversion.

          2.1 Any  holder of this Note will have the right at its  option at any
     time,  and from time to time,  prior to  receipt  of payment in full of the
     principal  amount of and  interest on this Note to convert,  subject to the
     terms and provisions  hereof,  all or a portion of the principal  amount of
     this Note and accrued interest thereon, into shares of the Company's Common
     Stock,  $.002 par value per  share,  at the  conversion  price  hereinafter
     provided.

                                       -3-


<PAGE>


     Notwithstanding the foregoing,  the holder shall not be entitled to convert
     this Note  until  six  months  from  issue  date,  except in the event of a
     transaction  referred to in Section 5 below, in which case the holder shall
     be entitled to convert this Note at any time after the public  announcement
     of such a transaction.

          2.2 To convert  this Note,  in whole or in part as provided  herein at
     the Holder's election, the Holder hereof shall surrender this Note and give
     written  notice to the Company of his  intention  to  convert,  stating the
     portion  of the Note that is to be  converted  and the name and  address of
     each  person in whose  name a share or shares of stock  issuable  upon such
     conversion  is to be  registered  and the  number of shares to be issued to
     each such person.

          2.3 As promptly as practical  after the surrender and giving of notice
     to convert as herein  provided,  the  Company  shall (i) pay the Holder the
     amount of  accrued  and unpaid  interest  on this Note to the date on which
     such conversion is made either in cash or by means of Additional  Principal
     Amount as set forth above; and (ii) deliver or cause to be delivered at its
     office or agency  maintained  for that purpose to or upon written  order of
     the Holder of the Note  certificates  representing the number of fully paid
     and  nonassessable  shares of Common  Stock of the Company  into which said
     Note is converted and, in the event of partial conversion, a new Note in an
     aggregate  principal amount equal to the unconverted  portion of said Note,
     dated as of the date to which  interest  has been paid,  and if no interest
     has been paid,  dated as of the date the Note is converted in part,  and in
     all other respects identical to the Note converted.

          2.4 The  conversion  price  for each  share of  Common  Sock  issuable
     pursuant  to the  conversion  of the Note  shall  initially  be One  Dollar
     ($1.00) per share in lawful money of the United States of America and shall
     be  adjusted  as  provided  in  Section 4  hereof,  and as  provided  below
     (hereinafter called the "Conversion Price").

     3. Reserved Shares.

          3.1 The Company covenants and agrees that it has reserved and shall at
     all times  reserve and keep  available out of its  authorized  but unissued
     Common  Stock,  solely  for the  purpose of issuing  such  shares  upon the
     conversion of the Notes (including any Additional  Principal Amount in lieu
     of interest),  the full number of shares of Common Stock  deliverable  upon
     the conversion of all Notes outstanding (including any Additional Principal
     Amount in lieu of  interest).  The  Company  covenants  and agrees that the
     shares of its Common Stock  delivered upon conversion of the Notes shall at
     the time of delivery of the  certificates  for such shares of Common Stock,
     be validly issued and outstanding and fully paid and  nonassessable  shares
     of Common Stock. The Company further  covenants and agrees that it will pay
     when due and payable any and

                                       -4-


<PAGE>

     all Federal and state  original issue taxes which may be payable in respect
     of the issue of the Notes or any shares of Common Stock upon the conversion
     of Notes. The Company shall not, however,  be required to pay any tax which
     may be payable in respect of any  transfer  involved  in the  transfer  and
     delivery of Notes,  any such tax being  payable by the Holder of such Notes
     at the time of surrender.

          3.2 Each  person in whose  name any  certificate  for shares of Common
     Stock is issuable  upon the exercise of this Note shall for all purposes be
     deemed to have become the holder of record of the Common Stock  represented
     thereby on, and such  certificate  shall be dated,  the date upon which the
     Note was duly  surrendered  and notice of conversion  was given;  provided,
     however, that if the date of such surrender and notice is a date upon which
     the stock  transfer  books of the Company are closed,  such person shall be
     deemed to have  become  the  record  holder  of such  shares  on,  and such
     certificate  shall be  dated,  the next  business  day on which  the  stock
     transfer books of the Company are open.

     4. Adjustments to Conversion Price.

          4.1 In case the  Company  shall at any time or from time to time after
     the date of  issuance of the Notes  issue any  additional  shares of Common
     Stock (or any  security  convertible  into  shares  of Common  Stock or any
     rights or options to purchase  shares of Common Stock) for a  consideration
     per share less than the Conversion Price in effect immediately prior to the
     issuance of such additional  shares,  or without  consideration,  then, and
     thereafter  successively  upon each such issuance,  the Conversion Price in
     effect  immediately  prior to the issuance of such additional  shares shall
     forthwith be reduced to a price determined by dividing:

               (a) An  amount  equal to the sum of (i) the  number  of shares of
          Common Stock outstanding immediately prior to such issuance multiplied
          by the then existing Conversion Price, plus (ii) the consideration, if
          any, received by the Company upon such issuance, by

               (b) The  total  number of  shares  of  Common  Stock  outstanding
          immediately after the issuance of such additional shares.

          4.2 The Company  shall not be required to make any  adjustment  of the
     Conversion  Price in  accordance  with  Section  4.1 if the  amount of such
     adjustment  shall be less than $.01, but in such case, any adjustment  that
     would  otherwise be required  then to be made shall be carried  forward and
     shall  be made  at the  time  of and  together  with  the  next  subsequent
     adjustment of the  Conversion  Price which,  together with all  adjustments
     thereof so carried forward, shall amount to not less than $.01.


                                       -5-


<PAGE>


          4.3 For the purpose of  adjustments  under  Section 4.1, the following
     provisions shall also be applicable:

               (a) In the case of the  issuance of  additional  shares of Common
          Stock for cash,  the  consideration  received by the Company  therefor
          shall be  deemed  to be the cash  proceeds  received  for such  shares
          without  deducting any  commissions or other expenses paid or incurred
          by the Company for any  underwriting  of, or otherwise  in  connection
          with, the issuance of such shares.

               (b) In case of the issuance  (otherwise  than upon  conversion of
          Notes) of additional shares of Common Stock for a consideration  other
          than cash or a consideration a part of which shall be other than cash,
          the amount of the  consideration  shall be determined in good faith by
          the Board of Directors of the Company.

               (c) In the case of the issuance by the Company  after the date of
          issuance of the Notes, of any security that is convertible into shares
          of Common Stock or any rights or options to purchase  shares of Common
          Stock,  (i) the  Company  shall be deemed to have  issued the  maximum
          number of shares of Common Stock deliverable upon the exercise of such
          rights or options or upon  conversion of such  securities and (ii) the
          consideration  therefor  shall  be  deemed  to be the  sum of (x)  the
          consideration  received by the Company for such convertible securities
          or for such  other  rights  or  options  as the  case may be,  without
          deducting  therefrom any expenses or  commissions  incurred or paid by
          the Company  for any  underwriting  or  issuance  of such  convertible
          security or right or option,  plus (y) the consideration or adjustment
          payment  to be  received  by  the  Company  in  connection  with  such
          conversion, plus (z) the minimum price at which shares of Common Stock
          are to be delivered  upon the exercise of such rights or options,  or,
          if no minimum  price is specified  and such shares are to be delivered
          at the option price related to the market value of the subject shares,
          an option price  bearing the same  relation to the market value of the
          subject  shares  at the time  such  rights or  options  were  granted,
          provided  that as to such options such further  adjustment as shall be
          necessary  on the  basis  of the  actual  option  price at the time of
          exercise shall be made at such time if the actual option price is less
          than the aforesaid assumed option price.

               (d) For the purpose hereof, any additional shares of Common Stock
          issued as a stock  dividend shall be deemed to have been issued for no
          consideration.

               (e) The number of shares of Common Stock at any time  outstanding
          shall  include (i) all  outstanding  common stock of the Company,  and
          (ii) the  aggregate  number of shares  deliverable  in  respect of the
          convertible securities, rights and options referred to in this Section
          4, provided  that,  to the extent that any such  options,  warrants or
          conversion  privileges are not exercised,  such shares shall be deemed
          to be  outstanding  only  until the  expiration  dates of the  rights,
          options or conversion privilege

                                       -6-

          or the prior  cancellation  thereof.  Notwithstanding  the  foregoing,
          there  shall  not be  taken  into  account,  for  the  purpose  of any
          computation made pursuant to Section 4, whether for the  determination
          of the number of shares of Common  Stock issued or  outstanding  on or
          prior to any date, or otherwise: (i) any options,  warrants, or rights
          to purchase shares of Common Stock of the Company included on Schedule
          2.4 to the Agreement, (ii) options to purchase up to 450,000 shares of
          Common Stock issued pursuant to the Company's Stock Option Plan if the
          exercise  price  thereof  is at least  $1.00 per  share,  or (iii) any
          shares of Common Stock  issued upon the exercise of any such  options,
          warrants, or conversion rights referenced in the foregoing clauses (i)
          and (ii).

               (f) Notwithstanding  the foregoing,  upon the expiration or other
          termination of such options,  rights or warrants, if any thereof shall
          not have been  exercised,  the number of shares of Common Stock deemed
          to be issued and  outstanding  pursuant to  subparagraphs  (d) and (e)
          shall be reduced by such number of shares of Common  Stock as to which
          options,  warrants  and/or  rights  shall have  expired or  terminated
          unexercised, and such number of shares of Common Stock shall no longer
          be deemed to be issued and outstanding,  and the Conversion Price then
          in effect shall  forthwith be readjusted  and  thereafter be the price
          which it would have been had adjustment  been made on the basis of the
          issuance  only of shares of Common Stock  actually  issued or issuable
          upon the exercise of those options, rights or warrants as to which the
          exercise rights shall have not have expired or terminated unexercised.

          4.4 If at any  time  or  from  time  to  time  the  Company  shall  by
     subdivision,  consolidation or  reclassification  of shares,  or otherwise,
     change as a whole, the outstanding  shares of Common Stock into a different
     number or class of shares, the shares issuable upon conversion of each Note
     and  the  Conversion   Price  per  share  shall  be   proportionately   and
     correspondingly  adjusted so as to give the Holder  substantially  the same
     rights as the Holder would have had if the Holder had  converted  this Note
     immediately prior to the occurrence of such event.

          4.5 In case the Company shall declare a dividend upon the Common Stock
     payable otherwise than out of earnings or earned surplus and otherwise than
     in Common Stock,  the Conversion Price in effect  immediately  prior to the
     declaration  of such dividend  shall be reduced by an amount equal,  in the
     case of a dividend in cash, to the amount thereof  payable per share of the
     Common  Stock,  or in the case of any  other  dividend,  to the fair  value
     thereof per share of the Common Stock as determined,  in good faith, by the
     Board of  Directors of the Company.  For the purposes of the  foregoing,  a
     dividend other than in cash shall be considered  payable out of earnings or
     earned  surplus only to the extent that such earnings or earned surplus are
     charged an amount equal to the fair value of such dividend as determined in
     good faith by the Board of Directors of the Company.  Such reductions shall
     take

                                       -7-

<PAGE>


     effect as of the date as of which the holders of Common Stock of record are
     entitled to such dividend.

          4.6 Irrespective of any adjustments or changes in the Conversion Price
     or the number of shares of Common Stock actually issuable under the several
     Notes,  the Notes shall continue to express the Conversion  Price per share
     and the number of shares issuable thereunder as expressed in the Notes when
     initially issued.

          4.7 The  Company  shall give notice to the Holder of any change in the
     Conversion Price under this Note and the method of calculation thereof. The
     Company shall give the Holder advance notice of any cash dividends,  rights
     offerings  and other  transactions  directly  for the benefit of holders of
     Common  Stock of the Company and any  transaction  referred to in Section 5
     below;  provided  that in any event such notice shall be provided  prior to
     the  applicable  record  date  for  or  the  effective  date  of  any  such
     transaction.

          4.8  The  Company  will  not,  by  amendment  of  its  Certificate  of
     Incorporation   or  through   any   reorganization,   transfer  of  assets,
     consolidation,  merger,  dissolution,  issue or sale of  securities  or any
     other  voluntary  action,   avoid  or  seek  to  avoid  the  observance  or
     performance  of any of the terms to be observed or  performed  hereunder by
     the Company but will at all times in good faith  assist in the carrying out
     of all the provisions of this Note and in the taking of all such actions as
     may be necessary or appropriate  in order to protect the conversion  rights
     of the Holders of the Notes.

     5. Merger.

     If, prior to the payment in full or  conversion  in full of the Notes,  the
Company shall at any time  consolidate  with or merge into another  corporation,
the  Holder  of each Note will  thereafter  be  entitled  to  receive,  upon the
conversion  thereof,  the securities or property to which a holder of the number
of shares of Common Stock then issuable  upon the  conversion of such Note would
have been entitled upon such consolidation or merger, and the Company shall take
such steps in connection with such  consolidation  or merger as may be necessary
to  assure  that  this  Note (or a new Note  issued  by the  succeeding  company
containing  exactly the same terms as this Note) shall remain in effect and that
the  provisions  of this  Note  shall  thereafter  be  applicable,  as nearly as
reasonably may be, in relation to any securities or property thereafter issuable
upon the  conversion  of the Notes.  A sale of all or  substantially  all of the
assets  of the  Company  for a  consideration  (apart  from  the  assumption  of
obligations)  consisting principally of securities or, a purchase of 50% or more
of the  Common  Stock by a person or a group of  related  people  pursuant  to a
tender  offer or  otherwise  shall be deemed a  consolidation  or merger for the
foregoing purposes. In the event of a consolidation

                                       -8-

<PAGE>



or  merger,  provided  that the  consideration  per share of Common  Stock to be
received by the Company's  shareholders is less than the Conversion  Price,  the
Holder  shall have the  option to put the Note to the  issuer for the  principal
amount of the Note, plus accrued interest; payment to be made at the time of the
closing of any such  consolidation or merger. In the event of a consolidation or
merger, provided that the consideration per share of Common Stock to be received
by the  stockholders  is equal to at least  two (2)  times  the then  Conversion
Price,  the Company shall have the right to prepay the Note in  accordance  with
the prepayment provisions set forth above.

     6. Fractional Shares.

     The  Company  shall  not be  required  to issue  certificates  representing
fractions of shares of Common Stock upon the conversion of Notes, but in respect
of any final  fraction  of a share it will make a payment  in cash  based on the
then market value of the Common Stock as determined  by the  Company's  Board of
Directors.

     7.  Covenants of the Company . The Company  covenants  and agrees that,  so
long as this Note remains outstanding and unpaid, in whole or in part:

     property,  before the same shall  become in default,  as well as all lawful
     claims for labor,  materials and supplies which, if unpaid,  might become a
     lien or charge upon such properties or any part thereof; provided, however,
     that the  Company  or such  subsidiary  shall  not be  required  to pay and
     discharge any such tax,  assessment,  charge,  levy or claim so long as the

          7.7 The Company will, promptly following the occurrence of an Event of

     statement of the Company's  President or Chief Financial  Officer to Holder
     setting  forth the details of such Event of Default or  condition  or event
     and the action which the Company intends to take with respect thereto;

     the Purchasers, grants to the holder of such indebtedness (or any

          8.7 A final judgement for the payment of money in excess of $75,000 is
     entered  against the Company or any subsidiary of the Company by a court of
     competent jurisdiction, and such

                                      -11-

<PAGE>


     judgment is not discharged (nor the discharge thereof duly provided for) in
     accordance with its terms, nor a stay of execution thereof procured, within
     thirty (30) days after the date such judgement is entered, and, within such
     period (or such longer  period  during which  execution of such judgment is
     effectively  stayed),  an appeal  therefrom has not been prosecuted and the
     execution thereof caused to be stayed during such appeal; or

          8.8 An  attachment  or  garnishment  is levied  against  the assets or

     Notes,  or any of them)  having an aggregate  face or  principal  amount in
     excess of $75,000,  or a default occurs in the performance or observance by
     the  Company of any  covenant or  condition  (other than for the payment of
     money)  contained in any note or agreement  evidencing or pertaining to any
     such  indebtedness,  which causes the maturity of such  indebtedness  to be
     accelerated  or  permits  the holder or  holders  of such  indebtedness  to
     declare the same to be due prior to the stated maturity thereof;

     then,  upon the  occurrence  of any such Event of  Default  and at any time
     thereafter,  the Holder of this Note shall have the right (at such Holder's
     option) to declare the principal of,  accrued  unpaid  interest on, and all
     other  amounts  payable  under this Note to be  forthwith  due and payable,
     whereupon  all such  amounts  shall be  immediately  due and payable to the
     Holder of this Note, without presentment,  demand,  protest or other notice
     of any kind, all of which are hereby expressly waived;  provided,  however,
     that in case of the occurrence of an Event of Default under any of Sections
     8.1,  8.2 or 8.4 above,  such  amounts  shall  become  immediately  due and
     payable without any such declaration by the Holder of this Note.

     9. Suits for Enforcement and Remedies. If any one or more Events of Default
shall occur and be continuing, the Holder may proceed to (i) protect and enforce
Holder's  rights either by suit in equity or by action at law, or both,  whether

in this Note or in any agreement or document referred to herein or in aid of the
exercise of any power granted in this Note

                                      -12-


<PAGE>


or in any agreement or document referred to herein,  (ii) enforce the payment of
this Note, or (iii) enforce any other legal or equitable  right of the Holder of
this Note.  No right or remedy  herein or in any other  agreement or  instrument
conferred  upon the Holder of this Note is intended to be exclusive of any other
right or remedy, and each and every such right or remedy shall be cumulative and
shall be in addition to every other right and remedy  given  hereunder or now or
hereafter existing at law or in equity or by statute or otherwise.

     10. Voting Rights.

     (a) So long as any of the principal amount or accrued interest on this Note
is still outstanding,  the Holder shall be entitled to vote on all matters voted
on by holders of Common  Stock,  voting  together  as a single  class with other
shares entitled to vote at all meetings of the  stockholders of the Corporation.
With  respect to any such vote,  the Holder shall be entitled to cast the number
of votes  equal to the  number  of votes  which  could be cast in such vote by a
holder of the shares of Common Stock into which this Note is  convertible on the
record date for such vote.  The  foregoing  voting rights are in addition to the
voting  rights that the Holder will obtain in respect of shares of Common  Stock
received upon conversion of this Note.

     (b) The Company  shall  provide the Holder with prior  notification  of any
meeting of the shareholders (and copies of proxy materials and other information
sent to shareholders).  In the event of any taking by the Company of a record of
its shareholders for the purpose of determining shareholders who are entitled to
receive  payment of any dividend or other  distribution,  any right to subscribe
for, purchase or otherwise acquire (including by way of merger, consolidation or
recapitalization) any share of any class or any other securities or property, or
to receive any other right, or for the purpose of determining  shareholders  who
are entitled to vote in  connection  with any Company,  the Company shall mail a
notice to the Holder, at least thirty (30) days prior to the consummation of the
transaction  or  event,  whichever  is  earlier),  of the date on which any such
action is to be taken for the purpose of such dividend,  distribution,  right or
other event,  and a brief  statement  regarding the amount and character of such
dividend, distribution, right or other event to the extent known at such time.

     11. Unconditional Obligation; Fees, Waivers, Other.

          11.1 The  obligations  to make the payments  provided for in this Note
     are absolute  and  unconditional  and not subject to any defense,  set-off,
     counterclaim, rescission, recoupment or adjustment whatsoever.

          11.2 If, following the occurrence of an Event of Default, Holder shall
     seek to enforce the collection of any amount

                                      -13-

 

<PAGE>


     of principal of and/or  interest on this Note,  there shall be  immediately
     due and payable from the Company,  in addition to the then unpaid principal
     of, and  accrued  unpaid  interest  on, this Note,  all costs and  expenses
     incurred by Holder in connection therewith,  including, without limitation,
     reasonable attorneys' fees and disbursements.

          11.3 No  forbearance,  indulgence,  delay or failure to  exercise  any
     right or remedy with  respect to this Note shall  operate as a waiver or as
     an acquiescence in any default, nor shall any single or partial exercise of
     any right or remedy preclude any other or further  exercise  thereof or the
     exercise of any other right or remedy.

          11.4  This  Note may not be  modified  or  discharged  (other  than by
     payment) except by a writing duly executed by the Company and Holder.

          11.5 The Company hereby  expressly  waives demand and  presentment for
     payment,  notice of  nonpayment,  notice of  dishonor,  protest,  notice of
     protest,  bringing of suit,  and  diligence in taking any action to collect
     amounts  called for hereunder,  and shall be directly and primarily  liable
     for the payment of all sums owing and to be owing hereon, regardless of and
     without  any  notice,  diligence,  act  or  omission  with  respect  to the
     collection of any amount  called for  hereunder or in  connection  with any
     right, lien,  interest or property at any and all times which Holder had or
     is existing as security for any amount called for hereunder.

     12. Miscellaneous.

          12.1 The  headings  of the  various  paragraphs  of this  Note are for
     convenience  of reference  only and shall in no way modify any of the terms
     or provisions of this Note.
