• Reaching a broader audience at lower cost

Broker Recruiting • Kicked off brokerage recruiting initiative in 2H 2009

• Sales reps with print brokerage background have historically been top

producers for IW

• Actively pursuing more key hires from a pool of thousands of independent

brokers

Web-based Sales • Initiative began December 2009, site launched February 2010

M&A Strategy

Build on prior M&A success:

Successful integrations

Primary source of sales professionals

Acquired talent contributed to 18 of 30 enterprise wins in 2009

Retention post earn-out of key performers has been outstanding

Revamping M&A activity:

Requiring more favorable terms, ROIC for INWK shareholders

Focused on small, tuck-in deals

Still the only credible buyer in a buyers’ market

Going forward expect more activity than in ’09 and less than ’07 and ’08
