What to do in this scenario

Scenario:

I have an approval from both the 1st and 2nd lender. 1st is IndyMac and the 2nd is SLS.

IndyMac's final settlement approval to them is $6,400 higher than what we offered on our initial EST HUD-1 ($430,000 was our offer on the HUD. They came back with $436,400 approval). SLS's approval is $2,508 higher than what we offered on the initial HUD-1. ($10,000 was our offer. Approved at $12,508).

I spoke to my negotatior at SLS, the one who hold's the 2nd. He will NOT budge on the approval amount. I asked him if I can convince IndyMac to come middle grounds with what you're demanding verses what IndyMac is willing to give the 2nd, would he resubmit for Investor re-approval. His answer was "No. Even if I did, I can guarantee you that this particular investor will come back with even a higher a demand."

I left a message for the negotiator at IndyMac to see how much I could squeeze out of her. The difference between what IndyMac wants to give the 2nd verses what SLS is demanding is over $9,000.

Here's my question:

1) Even if the agent's and/or the buyer were willing to contribute towards the $9,400 or so difference to get everyone paid what they want, (so we can close and move on), IndyMac wouldn't approve because the approval specifically states that no more than $3,000 be paid to the 2nd and anything additional shall go to IndyMac, right?

2) If I can convince IndyMac to raise the payoff to the 2nd a little more, do you think it's worth taking the risk to resubmit to the 2nd with a lower payoff amount compared to what they've already approved on based on what my negotiator said?

I hope this all made sense. I'd be more than willing to clarify if anyone needs. Thanks!
