7.1 The prospective bidder may modify the eligibility documents after they have been submitted, provided that the modification is received by the Procuring Entity prior to the deadline specified in Clause 5. The prospective bidder shall not be allowed to retrieve the original eligibility documents, but shall be allowed to submit another set equally sealed, properly identified, linked to the original bid marked as "ELIGIBILITY MODIFICATION," and stamped "received" by the BAC. Modifications received after the applicable deadline shall not be considered and shall be returned to the prospective bidder unopened.

7.3 Eligibility documents requested to be withdrawn in accordance with this Clause shall be returned unopened to the prospective bidder concerned. A prospective bidder may also express the intention not to participate in the bidding through a letter which should reach and be stamped by the BAC before the deadline for submission and receipt of eligibility documents. A prospective bidder who withdraws eligibility documents shall not be permitted to submit another set, directly or indirectly, for the same project.
