Hundred Thousand Dollars  ($1,200,000) to Four Million Three Hundred  Twenty-Two

          FOR VALUE RECEIVED, the undersigned,  The Network Connection,  Inc., a
          Georgia corporation (the "MAKER"), hereby promises to pay to the order
          of Interactive Flight Technologies,  Inc., a Delaware corporation, its
          successors  and  assigns  (the  "PAYEE"),  the  principal  sum of Four
          Million Three Hundred  Twenty-Two  Thousand Seven Hundred  Fifty-Seven
          Dollars  ($4,322,757),  together  with  interest  on  the  outstanding
          principal  balance  thereof  accrued from the date hereof:  (a) at the
          fixed rate of 9.5% per annum in respect of all periods during which no
          Event of Default (as such term is hereinafter  defined) is continuing;
          and (b) at the fixed rate of 12.5% in respect  of all  periods  during
          which any Event of Default is  continuing.  All  payments of principal
          and/or  interest shall be paid in lawful money of the United States of
          America in  immediately  available  funds to an account  designated by
          Payee.

     2. Paragraph 16 is hereby amended and restated in full to read as follows:

               16. CONVERSION RIGHTS.  Payee shall be entitled,  at any time and
          from  time to time and in its sole  discretion,  to  convert  all or a
          portion of the  principal  amount and accrued  interest due under this
          Note into  shares of the  Maker's  Series C 8%  Convertible  Preferred
          Stock,  $.01 par value,  Stated Value $1,000 per share (the "PREFERRED
          STOCK") or, at the option of Payee, into the Maker's Common Stock (the
          "COMMON  STOCK").  Any such  conversion  into Preferred Stock shall be
          effected at the rate of one share of  Preferred  Stock for each $1,000
          due  hereunder  which  Payee has elected to convert  (the  "CONVERSION
          RATE").  If Payee elects to convert all or a portion of the  principal
          amount and  accrued  interest  due under this Note  directly  into the
          Common Stock, the number of shares to be issued shall be calculated as
<PAGE>
          if such amount had first been converted to Preferred  Stock  hereunder
          (calculated  without regard to any  insufficiency of authorized shares
          of Preferred  Stock) and such resulting shares of Preferred Stock had,
          in turn,  immediately  been  converted to Common Stock at a conversion
          price per share  equal to the lowest of (a)  $1.50,  (b) 66.67% of the
          Current Market Price (as hereafter  defined),  (c) the price per share
          at which the Maker,  after the date of this Allonge,  issues and sells
          any  Common  Stock,  or  (d)  where  coupled  with  the  right  of the
          purchaser(s) thereof to demand that the Corporation register under the
          Securities Act of 1933 any Common Shares (not theretofore  registered)
          for which any warrants or options may be exercised or any convertible,
          exchangeable or exercisable securities may be converted,  exercised or
          exchanged,  (i) the  exercise  price of any such  warrants  or options
          issued  by the  Maker  after  the  date of this  Allonge,  or (ii) the
          conversion rate, exchange rate or exercise price, respectively, of any
          such convertible,  exchangeable or exercisable  security issued by the
          Maker  after  the  date of  this  Allonge,  except  for  stock  option
          agreements or stock incentive  agreements  issued pursuant to employee
          benefit  plans.  For purposes of this  Paragraph 16, the term "Current
          Market  Price"  means the  closing bid price as reported on the Nasdaq
          Stock Market (or if not then traded on such market,  on such  exchange
          or quotation system where such shares are then traded) for the trading
          day immediately preceding the Conversion Date.

          Payee may elect to  convert  by  delivering  to Maker,  by  facsimile,
          telecopier  or other  expedient  means of  transmission,  a notice  of
          conversion stating (i) the principal amount and/or accrued interest to
          be converted,  (ii) the number of shares of Preferred  Stock or Common
          Stock to be  issued  as a result  of such  conversion;  and  (iii) the
          person(s) in whose name the  Preferred  Stock or Common Stock is to be
          issued.  The  conversion of any portion of this Note and the resulting
          issuance of Preferred  Stock or Common  Stock shall be effective  upon
          the date that Maker receives the  corresponding  notice of conversion,
          and Maker shall deliver to Payee one or more  certificates  evidencing
          such shares no later than five days  following  such  effective  date.
          Upon a conversion  of all amounts due  hereunder,  Payee shall deliver
          the original Note (including all Allonges), marked "PAID," to Maker no
          later than five days following the delivery to Maker of the conversion
          notice.  In the event of a  conversion  of less than all  amounts  due
          hereunder,  (A) no  principal  amount  under the Note  shall be deemed
          converted  unless and until all accrued  interest under the Note shall
          be first  converted;  and (B) the portion of the amounts due hereunder
          that are so converted  shall be deemed repaid.  The parties shall mark
          on the grid attached to the Fourth Allonge to Secured  Promissory Note
          dated May 10, 1999 the facts  related to such partial  conversion  and
          shall  confirm the  accuracy of the entry by signing next to each such
          entry.
<PAGE>
     3. Any agreement to subordinate, or any subordination,  of the indebtedness
represented  by the Note to bank or  finance  company  indebtedness,  which  may
heretofore have been given by Payee, is null and void and of no force or effect.
Maker  represents and warrants to Payee that since execution of the Note,  Payee
retains a first priority security interest in the Collateral granted by Maker to
Payee  pursuant to that certain  Security  Agreement  dated  January 25, 1999 as
amended,  ("SECURITY  AGREEMENT").  The Maker's  obligations  under the Note, as
amended  hereby,  shall be and are deemed to be secured  by the  Collateral  and
subject to the terms of the Security  Agreement,  all of which are confirmed and
ratified  as of the date  hereof,  including,  but not  limited  to,  all of the
representations, warranties and covenants therein.

     4. In all other  respects,  the Note is confirmed,  ratified,  and approved
and,  as amended  by this  Seventh  Allonge,  shall  continue  in full force and
effect.

     IN WITNESS WHEREOF,  Maker and Payee have caused this Seventh Allonge to be
executed and delivered by their  respective duly  authorized  officers as of the
day and year first above written.

                                        THE NETWORK CONNECTION INC.
