Item 2.  Acquisition or Disposition of Assets
- ---------------------------------------------

On December 17, 1998, UniComp, Inc. (the "Company") completed the sale of
certain assets (the "Assets") of the Company's Northern Ireland subsidiary,
Aurora UniComp Limited, to Aurora SX3 Limited (the "Sale"). Aurora UniComp
Limited supplies and maintains computer hardware and software. The Assets
disposed of include, but are not limited to, the following: plant machinery and
motor vehicles, computer and office equipment, furniture, premises, tradename,
investments, and intellectual property rights. The Sale was consummated in
accordance with the terms of that certain Agreement for the Sale and Purchase of
Certain Assets and the Goodwill of Aurora UniComp Limited between Aurora UniComp
Limited, Aurora SX3 Limited, and UniComp, Inc., dated December 17, 1998 (the
"Sale Agreement").

The consideration paid to the Company in connection with the Sale was as
follows: (i) approximately 4.0 million pounds sterling (approximately $ 6.7
million U.S. as of December 17, 1998), of which 0.2 million pounds sterling
(approximately $ 0.3 million U.S. as of December 17, 1998) is being withheld
pending final calculation of certain completion accounts as set forth in detail
in the Sale Agreement; and (ii) assumption of debt of Aurora UniComp Limited
totaling approximately 3.3 million pounds sterling (approximately $ 5.5 million
U.S. as of December 17, 1998).  In addition, Aurora SX3 Limited and UniComp
Holdings (UK) Limited executed and entered into a two-year loan whereby Aurora
SX3 Limited loaned 0.75 million pounds sterling (approximately $ 1.2 million
U.S. as of December 17, 1998) to UniComp Holdings (UK) Limited (the "Loan") and
agreed to loan an additional 0.25 million pounds sterling after UniComp Holdings
(UK) Limited timely meets the first twelve installment payments.  The Loan bears
annual interest at the rate of .5% above the base lending rate of the Bank of
Ireland and the Loan shall be repaid in twenty-four equal monthly installment
payments of principle and Interest.

The total consideration paid in the Sale was determined through arm's length
negotiations between the parties. Neither the Company nor Aurora UniComp,
Limited, nor any of their affiliates had, or to the knowledge of the Company
or Aurora UniComp Limited, did any director or officer or any associate of any
such director or officer of the Company nor Aurora UniComp, Limited, have any
material relationship with Aurora SX3 Limited prior to the Sale.

                                                                               2

    the basis upon which the Purchaser is making a claim against the Vendor and
    the estimated total amount of liability which results) has been given to the

(3) No liability shall attach to the Vendor in respect of any claims under the

         voluntarily done or omitted to be done after Completion by the
         Purchaser otherwise than in the ordinary course of business.

    (b)  if and to the extent that it arises or is increased as a result only of

          counterclaim, subrogation, indemnity, proof in liquidation or
          otherwise and whether from contribution or otherwise, all together

          demand.

4.5  This Guarantee shall be in addition to and shall not affect or be affected

by the Creditor from time to time for the discharge and performance of any of
the liabilities and obligations of each of the Principal Debtors to the
Creditor.

5    INTEREST

     (a)  Each of the Guarantors agrees to pay interest to the Creditor at the
          Interest Rate on all sums demanded under this Guarantee from the date

          on which the relevant damages, losses, costs or expenses arose in
          respect of which such demand has been made, in each case until, but
          excluding the date of actual payment.

     (b)  Each of the Guarantors agrees to pay interest to the Creditor at the
          Interest Rate after as well as before judgment.

accordance with the usual practice of the Creditor.

     (c)  The Creditor shall not be entitled to recover any amount in respect of
          interest both under this Guarantee and any of the Loan Agreement in

<PAGE>
 
     (a)  The Creditor may place to the credit of a suspense account any monies
          received under or in connection with this Guarantee in order to

          all of its claims against any and each of the Principal Debtors and
          any other person.

     (b)  The Creditor may, at any time, apply any of the monies referred to in
          clause 6(a) in or towards satisfaction of any of the monies,
          obligations and liabilities and the subject of this Guarantee as the
          Creditor, in its absolute discretion, may from time to time
          conclusively determine.

7    APPROPRIATION

application by the Creditor of any sums received by the Creditor from any of the
Guarantors under, or pursuant to, any of the terms of this Guarantee.

8    DISCHARGE TO BE CONDITIONAL

Any release, discharge or settlement between any of the Guarantors and the
Creditor in relation to this Guarantee shall be conditional upon no right,
security, disposition or payment to the Creditor by any of the Guarantors and
the Principal Debtor and any other person being void, set aside or ordered to be
refunded pursuant to any enactment or law relating to breach of duty by any
person, bankruptcy, liquidation, administration, the protection from creditors
generally or insolvency or for any other reason.

If any such right, security, disposition or payment is void or at any time so

discharge or settlement had not occurred and any such security, disposition or
payment had not been made.

                 case is binding on it.

     (b)  If any deduction or withholding is required by any law, practice or
          regulation (whether or not such practice or regulation has the force
          of law) in respect of any payment due from any of the Guarantors under
          this Guarantee or is in any event made, the relative sum payable by
          any Guarantor shall be increased so that, after making the minimum
          deduction or withholding so required, that Guarantor shall pay to the
          Creditor and the Creditor shall receive and be entitled to retain on
          the due date for payment a net sum at least equal to the sum which it
          would have received had no such deduction or withholding been required
          to be, or had in fact been, made.

     (c)  Each of the Guarantors shall promptly deliver or procure the delivery
          to the Creditor of all receipts issued to it evidencing each deduction
          and withholding which it has made.

     and, in either case, the increased payment would not have become payable if
     the Creditor had been a Qualifying Bank.

10   DEMANDS AND NOTIFICATION BINDING

due and payable under or in connection with any of the provisions of this
Guarantee shall, in the absence of manifest error, be conclusive and binding on

officer or agent of the Creditor and (without prejudice to any other effective
means of serving it) may be served on the relative Guarantor personally or by
post and either by delivering it to any officer of that Guarantor at any place
or by despatching it addressed to that Guarantor at the Guarantor's registered
or principal office for the time being or a place of business of that Guarantor
last known to the Creditor. Any such demand or notice delivered personally shall
be deemed to have been received immediately upon delivery. Any such demand or
notice sent by post shall be deemed to have been received at the opening of
business in the intended place of receipt on the business day following the day
on which it was posted, even if returned undelivered.

13       TRANSFERS

13.1     This Guarantee is freely assignable or transferable by the Creditor.

                                                                              11

13.2 None of the Guarantors may assign any of its rights and may not transfer
any of its obligations under this Guarantee or enter into any transaction which
would result in any of those rights or obligations passing to another person.

13.3 The Creditor may disclose to any person related to the Creditor and/or any
person to whom it is proposing to transfer or assign or has transferred or
assigned any of its rights under this Guarantee any information about any of the
Guarantors and any person connected or associated with it. Each of the
Guarantors represents and warrants that it has (and, subject to any contrary
requirement of law, will maintain) any necessary authority by or on behalf of
any such person to agree to the provisions of this Clause.

14   CURRENCY INDEMNITY

If, under any applicable law or regulation or pursuant to a judgment or order
being made or registered against any Guarantor or the liquidation of that
Guarantor or without limitation for any other reason, any payment under or in
connection with this Guarantee is made or falls to be satisfied in a currency
(the `payment currency') other than the currency in which such payment is
expressed to be due under or in connection with this Guarantee (the `contractual
currency') then, to the extent that the amount of such payment actually received
by the Creditor, when converted into the contractual currency at the rate of
exchange, falls short of the amount due under or in connection with this
Guarantee, that Guarantor, as a separate and independent obligation, shall
indemnify and hold harmless the Creditor against the amount of such shortfall.
For the purposes of this Clause, `rate of exchange' means the rate at which the
Creditor is able on or about the date of such payment to purchase, in accordance
with its normal practice, the contractual currency with the payment currency and
shall take into account (and that Guarantor shall be liable for) any premium and
other costs of exchange including any taxes or duties incurred by reason of any
such exchange.

15.1 No delay or omission on the part of the Creditor in exercising any right or
remedy

                                                                              12
<PAGE>
 
under this Guarantee shall impair that right or remedy or operate as or be taken
to be a waiver of it; nor shall any single partial or defective exercise of any
such right or remedy preclude any other or further exercise under this Guarantee
of that or any other right or remedy.

15.2 The Creditor's rights under this Guarantee are cumulative and not exclusive
of any rights provided by law and may be exercised from time to time and as
often as the Creditor deems expedient.

15.3 Any waiver by the Creditor of any terms of this Guarantee, or any consent
or approval given by the Creditor under it, shall only be effective if given in
writing and then only for the purpose and upon the terms and conditions, if any,
on which it is given.

15.4 If at any time any one or more of the provisions of this Guarantee is or
becomes illegal, invalid or unenforceable in any respect under any law of any
jurisdiction, neither the legality, validity and enforceability of the remaining
provisions of this Guarantee nor the legality, validity or enforceability of
such provision under the law of any other jurisdiction shall be in any way
affected or impaired as a result.

17.3  Nothing contained in this Clause shall limit the right of the Creditor to

jurisdiction, nor shall the taking of any such proceedings in one or more
jurisdictions preclude the taking of proceedings in any other jurisdiction,
whether concurrently or not (unless precluded by applicable law).

17.4 Each of the Guarantors irrevocably waives any objection which it may have
now or in the future to the courts of Northern Ireland being nominated for the
purpose of this Clause on the ground of venue or otherwise and agrees not to
claim that any such court is not a convenient or appropriate forum.
