per share, for  an  aggregate  purchase  price  of  $45,000,001.92.  All of such
purchase was made using funds which Oak Investment Partners  XI  had  raised for
investment purposes and none were made using borrowed funds.  All of such shares
of  Series  A  Preferred  Stock  were  then  converted,  in  the aggregate, into
6,633,255  shares  of Common Stock at the time of the Company's  initial  public
offering.  Thereafter, Oak Investment Partners XI made the following open market
purchases, each of which  was  made using funds which Oak Investment Partners XI
had raised for investment purposes  and none were made using borrowed funds: (i)

in this  Schedule  13D  (most  specifically, Items 2 and thereof) for investment
purposes only.

      Depending  on  prevailing  market,  economic  and  other  conditions,  the
Reporting Persons may from time to time acquire additional shares of the capital
stock  of  the Company or engage in  discussions  with  the  Company  concerning
further acquisitions  of  shares  of the capital stock of the Company or further
investments in the Company.  Each of  the  Reporting  Persons  intends to review

developments  affecting the Company, the Company's business and prospects, other
investment and  business  opportunities  available  to  the  Reporting  Persons,
general stock market  and economic conditions, tax considerations and other
factors considered relevant, may decide at any time to increase or to decrease
the size of his, her or its investment  in the Company (in each case, all but

acquisition  by any person of additional  securities  of  the  Company,  or  the

dividend policy of the Company; (f) any  other  material change in the Company's
