         FOR VALUE RECEIVED, the undersigned, SeraNova, Inc. (the "Obligor"), a
New Jersey corporation, having its principal office at 499 Thornall Street,

Inc. (the "Holder"), a New Jersey corporation, at the office of the Holder at
499 Thornall Street, Edison, New Jersey 08837 or at such other location as the
Holder may designate from time to time, the principal amount of fifteen million

per annum equal to one half of one percent (1/2%) above the Prime Rate as
reported in the Wall Street Journal on the date of this Note, which interest
shall be payable at such time as set forth hereunder. Interest shall be
calculated on the basis of a year of 365 days and for the number of days

bear interest at the maximum rate of interest allowed by applicable law. The
payments of principal and interest hereunder shall be made in coin or currency
of the United States of America which at the time of payment shall be legal
tender therein for the payment of public and private debts.

         This Note shall be subject to the following additional terms and
conditions:

          1.      Payments. Unless prepaid in full pursuant to Section 2 or
                  Section 7 hereof, all unpaid principal shall be due and
                  payable in full on July 31, 2001 (the "Maturity Date"). In the
                  event that any payment to be made hereunder shall be or become
                  due on a Saturday, Sunday or any other day which is a legal
                  bank holiday under the laws of the State of New Jersey, such
                  payment shall be or become due on the next succeeding business
                  day.

          2.      Optional Prepayment. The Obligor shall have the right at any
                  time to prepay the principal hereof in whole or in part,
                  without premium or penalty, prior to the Maturity Date,
                  provided that interest on the principal hereof to be so
                  prepaid, accrued to the date of such prepayment, shall be paid
                  concurrently therewith. Amounts prepaid under the terms of
                  this Note shall be applied in the discretion of the Holder.

          3.      Mandatory Prepayment; Application of Proceeds From Financing.
                  Notwithstanding any provision herein to the contrary, the
                  Obligor shall make a mandatory prepayment of principal in the
                  amount of three million dollars ($3,000,000) on or before
                  September 30, 2000. Further, in the event that the Obligor
                  consummates any debt or equity financing (excluding its
                  proposed credit facility with Fleet Credit Corporation), the
                  Obligor shall first apply the proceeds therefrom to make a
                  mandatory prepayment of the balance due under this Note in
                  accordance with the schedule set forth below until the balance
                  of principal and accrued interest due under this Note is paid
                  in full. The following schedule of mandatory prepayments shall
                  be based on the cumulative gross proceeds resulting from any
                  one or more debt or equity financings by the Obligor:

                     a)    up to $2,000,000, no mandatory prepayment shall be
                           made from Obligor to Holder;

                     b)    from $2,000,000.01 to $10,000,000, Obligor shall make
                           a mandatory prepayment equal to 50% of the net
                           proceeds in excess of $2,000,000;

                     c)    from $10,000,000.01 to $15,000,000, Obligor shall
                           make a mandatory prepayment equal to 75% of the net
                           proceeds in excess of $10,000,000; and

                     d)    in excess of $15,000,000, Obligor shall make a
                           mandatory prepayment of all of the net proceeds in
                           excess of $15,000,000.

                  Notwithstanding the above, in the event that the Obligor
                  consummates a single debt or equity financing of at least
                  $20,000,000, the Obligor shall make a mandatory prepayment of
                  the entire balance due under this Note. Amounts prepaid under
                  the terms of this Note shall be applied in the discretion of
                  the Holder. Nothing herein shall be construed to waive the
                  Obligor's obligation to repay all amounts outstanding
                  hereunder on the Maturity Date.

          4.      No Waiver. No failure or delay by the Holder in exercising any
                  right, power or privilege under this Note shall operate as a
                  waiver thereof nor shall any single or partial exercise
                  thereof preclude any other or further exercise thereof or the
                  exercise of any other right, power or privilege. The rights
                  and remedies herein provided shall be cumulative and not
                  exclusive of any rights or remedies provided by law. No course
                  of dealing between the Obligor and the Holder shall operate as
                  a waiver of any rights by the Holder.

          5.      Waiver of Presentment and Notice of Dishonor. The Obligor and
                  all endorsers, guarantors and other parties that may be liable
                  under this Note hereby waive presentment, notice of dishonor,
                  protest and all other demands and notices in connection with
                  the delivery, acceptance, performance or enforcement of this
                  Note.

          6.      Place of Payment. All payments of principal of this Note and
                  the interest due thereon shall be made at such place as the
                  Holder may from time to time designate in writing to the
                  Obligor.

          7.      Events of Default. The entire unpaid principal amount of this
                  Note and the interest due thereon shall, at the option of the
                  Holder exercised by written notice to the Obligor, forthwith
                  become and be due and payable, without presentment, demand,
                  protest or other notice of any kind, all of which are hereby
                  expressly waived, if any one or more of the following events
                  (herein called "Events of Default") shall have occurred (for
                  any reason whatsoever and whether such happening shall be
                  voluntary or involuntary or come about or be effected by
                  operation of law or pursuant to or in compliance with any

                           interest due thereon when and as the same shall
                           become due and payable, whether at maturity, or by
                           acceleration or otherwise, and such default shall
                           have continued for a period of five days;

          8.      Remedies. In case any one or more of the Events of Default
                  specified in Section 7 hereof shall have occurred and be
                  continuing, the Holder may proceed to protect and enforce its
                  rights either by suit in equity and/or by action at law,
                  whether for the specific performance of any covenant or

                  of this Note shall for any reason be held invalid, illegal or
                  unenforceable in any respect, such invalidity, illegality or
                  unenforceability shall not affect any other provision of this
                  Note, but this Note shall be construed as if such invalid,
                  illegal or unenforceable provision had never been contained
                  herein.

          11.     Governing Law. This Note and the rights and obligations of the

invoice or other written request for payment (which will detail the costs and
purposes for such costs).

Certain other costs may be incurred by Intelligroup on behalf of both parties,
which may include but are not be limited to (i) cost of general liability,
property and casualty, and other business insurance coverages (prior to SeraNova
becoming a publicly held entity); and (ii) costs of outside retained recruiting
firms. Intelligroup may recover a proportionate share of such costs from
SeraNova upon presentment to SeraNova in the form of an invoice or other written
request for payment (which will detail the costs and purposes for such costs).
Such proportion will be determined by mutual agreement of the parties.
