Group-stage contracts summing to more than two

In a four-team group exactly two teams qualify, and a contract on each team pays $1$ if it qualifies. The prices are $0.95$, $0.72$, $0.35$ and $0.03$. With zero interest, and the freedom to buy or sell contracts and bonds paying $1$, what up-front credit does an arbitrage provide?

$0.05$. The four contracts together always pay $2$, but they are priced at $2.05$. Sell one of each and buy two bonds, taking in $0.05$ now with a payoff that nets to zero.
