home purchase contract?

I am in the middle of buying a house. Date of Ratification is on 10/24 and is subject to financing. I was going to use realtor recommended mortgage broker. I notified the broker on 10/24 regarding the ratified contract requesting Rate and GFE. They got back to me on 10/28 with a loan application with above market rate with 0 point (i have 760+ credit score) and outrageous closing cost. The purchase contract has this statement 5 Financing: "Purchaser shall make written application for such loan within seven days after the date of Ratification". Does this clause mean? is it too late to shop around? Were they postponing rate and closing cost until 10/28 so I couldnt shop around? Is sending in loan document satisfied this contingency clause? do I have to SIGN that mortgage broker loan application by today to satisfy this clause? Mortgage broker is now rushing me to sign the mortgage loan disclosures
