Indemnity Clause in Sales Deed

Dear Mr. Kalaiselvan, We are selling a property in Bangalore and buyer has included some detailed clauses to indemnify them. A couple of them look a bit unreasonable. Need your suggestions on the indemnity clauses. e.g. a) The PURCHASER and her successors-in-interest hereinafter shall be entitled to have, hold, own and enjoy the Schedule Property by virtue of this Deed of Absolute Sale absolutely from generation to generation in perpetuity and forever without any impediment from any person or persons whatsoever. b) The VENDORS further covenant with the PURCHASER that they will always REIMBURSE or will resolve at their own cost any/all risks and indemnify the PURCHASER, her heirs and assigns against all losses and expenses incurred and damages sustained on account of prior encumbrances of any nature suppressed by the VENDORS, claims, charges, clogs, litigations, Court/s attachments, Hindrances, cesses, pending liabilities with regard to income tax, wealth tax, gift tax, property taxes or any other kind of tax which would create a charge and interruptions of any nature whatsoever and from whomsoever or on account of any defect in title, latent or patent, which the PURCHASER could otherwise discover later on in respect of the Schedule Property hereby conveyed. c) The VENDORS declare and assure the PURCHASERS that all the minor rights or any other right, title, claim, interest are protected and in case of any such claims that may arise in future all such claims etc., will be met by the VENDORS alone at their own cost and risk out of their own personal assets etc.,.
