Issues to Consider

•There are a number of factors to consider in evaluating Oak Tree’s current situation

Limited Cash Balance

•IMS strategy would need significant additional CapEx

•Additional financing, if possible, would be on significantly onerous terms

•Capital required for ongoing public company infrastructure costs including interest settlement on AV convert

Revenue Visibility

•Actual results for each of the last three quarters have been below management’s internal plan

•Preliminary Q1 2006 results appear to be below Board approved management plan

Competitive Concerns

•Oak Tree’s current scale creates structural competitive hurdles

•Recent loss of Sprint contract – 32% of total revenues in 2005

•Customer concentration issue – apart from Sprint, Oak Tree derives 37% of its revenue from Vodafone and Nokia

•Consolidation in the end market may exert further price pressure

Management Turnover

•VP of Sales, General Counsel and CFO have all turned over in the past few months

Lack of Visibility on Wall Street

•Limited Analyst coverage

•Extremely low institutional ownership

•Limited liquidity in the stock

•NASDAQ de-listing notice

LTM Stock Price Performance

•Oak Tree’s stock has exhibited continuous weakness over the past twelve months

Canaccord Adams – 03/13/06 | “Austin Raises Offer” Peter Misek

•In our opinion, the latest Austin Ventures offer is an improvement that signifies Austin’s dedication to the deal, and the valuation is closer to current market valuations of the firm. The support for this transaction by Oak Tree’ Special Committee of independent directors indicates that the committee believes this is the best alternative for the firm at this time.

•With the increased offer price of US$3.34 being approximately 11% higher than our target price prior to the original offer, we recommend to shareholders to TENDER their holdings and institute a target price of US$3.34 based on this offer.

Paradigm Capital – 03/13/06 | “Oak Tree is Gone” Barry Richards

•Oak Tree announced that Austin Ventures had raised its bid from US$3.07 to US$3.34 and that the Board at Oak Tree had accepted the bid. The revised bid is a 9% increase but still falls below our $3.50 target price and below the pre-bid closing price US$3.64. Austin Ventures owns 10% of the stock outstanding, before converting its debenture, which increases that number to almost 40% of the stock. We believe AV needs about 50% of the votes from stock it doesn’t own and 66.7% of the total votes.

•Overall, we believe the bid is still low, but fully expect that AV will get the votes it needs to complete this transaction. Furthermore, we do not expect another bidder. We recommend that shareholders tender into this revised offer.

Canaccord Adams – 02/17/06 | “Revenue Concerns Persist” Peter Misek

•We remain concerned that Oak Tree’s top line, even excluding the Sprint contract loss, continues to decline. By our estimates, the company’s Q4 revenue (excluding Sprint) would have been relatively flat sequentially and down approximately 20% Y/Y. We believe that the likelihood of management being able to backfill the Sprint loss in a timely fashion is declining given the erosion in non-Sprint revenue we are seeing.

•We are maintaining our HOLD recommendation despite the weak Q4 results for three main reasons: Oak Tree is positioned in an attractive market that is poised for growth, the company has established relationships with large industry players like Vodafone, Ericsson and Nokia, and the company’s valuation at 1.4x EV/Sales is not overly excessive,
