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

         On February  10,  1999,  the  Registrant  acquired by merger all of the
outstanding  capital  stock of A  Business  Conference-Call,  Inc.  ("ABCC"),  a
Minnesota corporation, from ABCC's two stockholders, Daniel L. Barber and Robert
M.  Kalla,  for a  purchase  price of $15.2  million  in cash plus (i)  $216,672
(subject to final adjustment) related to tax reimbursements  discussed below and
(ii) $677,074 (subject to final adjustment) based on ABCC's closing date balance
sheet, equal to the balances of cash plus accounts receivable (net of a bad debt
reserve of 5%) less all  liabilities  as of the closing date.  In addition,  the
Registrant incurred approximately $200,000 of acquisition costs.

         ABCC has 576  teleconferencing  ports and 45  employees as of September
30, 1998.  ABCC services a general  corporate  clientele with a specialty in the
communications industry.

         The Registrant and ABCC made an election to treat the purchase and sale
of the capital  stock of ABCC as a purchase and sale of assets.  The  Registrant
reimbursed the stockholders of ABCC $216,672 (subject to final adjustment),  the
difference  between the taxes incurred by such  stockholders as a result of such
election and the taxes which would have been incurred by such  stockholders  had
no such election been made.

         Mr.  Barber and Mr.  Kalla  each  entered  into a  two-year  employment
contract with the Registrant and received an incentive  stock option to purchase
37,500 shares of the Registrant's Common Stock at an exercise price of $8.00.

         The funds used by the  Registrant  to purchase  ABCC were obtained from
the sale of 4,600,000  shares of the  Registrant's  Common Stock  offered to the
public through an initial  public  offering (the "IPO") on Form S-1 (File Number
333-53395)(the  "Registration  Statement") which closed  simultaneously with the
Registrant's acquisition of ABCC.

Item 5. Other Events:
- ---------------------

A.  On  February  10,  1999,  the  Registrant  acquired  by  merger  all  of the
outstanding  capital stock of Conference Pros  International,  Inc.  ("CPI"),  a
Texas corporation,  from Michael Burns,  CPI's sole stockholder,  for a purchase
price of $6.0 million in cash plus $27,610 (subject to final adjustment) related
to tax  reimbursements  discussed  below. In addition,  the Registrant  incurred
approximately  $100,000 of acquisition costs and assumed approximately  $464,000
of indebtedness (based on CPI's September 30, 1998 balance sheet).

         CPI has 920 teleconferencing ports and 32 employees as of September 30,
1998. CPI services a general corporate clientele.

         The  Registrant and CPI made an election to treat the purchase and sale
of  capital  stock of CPI as a  purchase  and  sale of  assets.  The  Registrant
reimbursed Mr. Burns $27,610 (subject to final adjustment), the difference (less
$100,000)  between  the taxes  incurred by the  stockholder  as a result of such
election and the taxes which would have been incurred by the  stockholder had no
such election been made.

         Mr.  Burns  entered  into  a  two-year  employment  contract  with  the
Registrant  and  received  incentive  stock  options for the  purchase of 75,000
shares of the Registrant's Common Stock at an exercise price of $8.00.

         The funds used by the Registrant to purchase CPI were obtained from the
sale of Common Stock in the IPO.

B.  On  February  10,  1999,  the  Registrant  acquired  by  merger  all  of the
outstanding  capital stock of A Better Conference,  Inc. ("ABCI"),  a California
corporation,  from ABCI's stockholders,  Otis Cranford,  Patricia Cranford,  and
Matthew  Cranford,  for a purchase price of $6.2 million in cash. The Registrant
also  incurred   approximately   $100,000  of  acquisition   costs  and  assumed
approximately  $471,000  of  indebtedness  (based on ABCI's  September  30, 1998
balance sheet).

         ABCI has 432  teleconferencing  ports and 27  employees as of September
30, 1998.  ABCI services a general  corporate  clientele with a specialty in the
software, financial services and legal services industries.

         Patricia A.  Cranford and Matthew  Cranford  entered into  two-year and
three-year employment contracts with the Registrant,  respectively, and received
incentive  stock  options for the  purchase  of 50,000 and 25,000  shares of the
Registrant's Common Stock, respectively, at an exercise price of $8.00.

         The funds used by the  Registrant  to purchase  ABCI were obtained from
