PGI 204.7105 Contract exhibits and attachments.       (a) *Use of exhibits*.          (1) Exhibits may be used instead of putting a long list of contract line items or subline items in the contract schedule. Exhibits are particularly useful in buying spare parts.          (2) When using exhibits, establish a contract line or subline item and refer to the exhibit.          (3) Identify exhibits individually.          (4) Each exhibit shall apply to only one contract line item or subline item.          (5) More than one exhibit may apply to a single contract line item.          (6) Data items on a DD Form 1423, Contract Data Requirements List, may be either separately priced or not separately priced.          (i) Separately priced. When data are separately priced, enter the price in Section B of the contract.          (ii) Not separately priced. Include prices in a priced contract line item or subline item.          (7) The contracting officer may append attachments to exhibits, as long as the attachment does not identify a deliverable requirement that has not been established by a contract line item or subline item or exhibit line item.          (8) Include exhibit line items and associated information in the electronically distributed contract documents identified in PGI                 204.201             (3)(i)(A) and (B).          (b) *Numbering exhibits and attachments*.          (1) Use alpha characters to identify exhibits. The alpha characters shall be either single or double capital letters. Do not use the letters I or O.          (2) Once an identifier has been assigned to an exhibit, do not use it on another exhibit in the same contract.          (3) The identifier shall always appear in the first or first and second positions of all applicable exhibit line item numbers.          (4) If the exhibit has more than one page, cite the procurement instrument identification number, exhibit identifier, and applicable contract line or subline item number on each page.          (5) Use numbers to identify attachments.          (c) *Numbering exhibit line items*.          (1) Criteria for establishing. The criteria for establishing exhibit line items are the same as those for establishing contract line items (see DFARS 204.7103).          (2) Procedures for numbering.          (i) Number items in an exhibit in a manner similar to contract line items.          (ii) Number line items using a four-position number.          (A) The first position or the first and second position contain the exhibit identifier.          (B) The third and fourth positions contain the alpha or numeric character serial numbers assigned to the line item when using a double letter exhibit identifier. The second, third and fourth positions contain the alpha or numeric character serial numbers assigned to the line item when using a single letter exhibit identifier.          (iii) Exhibit line item numbers shall be sequential within the exhibit.          (3) Examples.          (i) Two-position serial number for double letter exhibit identifier.
