2. Each State Party shall be obliged to accept observation flights over its territory in accordance with the provisions of this Treaty.

3. Each State Party shall have the right to conduct a number of observation flights over the territory of any other State Party equal to the number of observation flights which that other State Party has the right to conduct over it.

4. The total number of observation flights that each State Party is obliged to accept over its territory is the total passive quota for that State Party. The allocation of the total passive quota to the States Parties is set forth in Annex A, Section I to this Treaty.

5. The number of observation flights that a State Party shall have the right to conduct each year over the territory of each of the other States Parties is the individual active quota of that State Party with respect to that other State Party. The sum of the individual active quotas is the total active quota of that State Party. The total active quota of a State Party shall not exceed its total passive quota.

6. The first distribution of active quotas is set forth in Annex A, Section II to this Treaty.

7. After entry into force of this Treaty, the distribution of active quotas shall be subject to an annual review for the following calendar year within the framework of the Open Skies Consultative Commission. In the event that it is not possible during the annual review to arrive within three weeks at agreement on the distribution of active quotas with respect to a particular State Party, the previous years distribution of active quotas with respect to that State Party shall remain unchanged.

8. Except as provided for by the provisions of Article VIII, each observation flight conducted by a State Party shall be counted against the individual and total active quotas of that State Party.

9. Notwithstanding the provisions of paragraphs 3 and 5 of this Section, a State Party to which an active quota has been distributed may, by agreement with the State Party to be overflown, transfer a part or all of its total active quota to other States Parties and shall promptly notify all other States Parties and the Open Skies Consultative Commission thereof. Paragraph 10 of this Section shall apply.

10. No State Party shall conduct more observation flights over the territory of another State Party than a number equal to 50 per cent, rounded up to the nearest whole number, of its own total active quota, or of the total passive quota of that other State Party, whichever is less.

For the purposes of determining the sensitometric characteristics of aerial film materials in accordance with its own national methodology, each State Party shall have the right to receive, upon request, unexposed samples of all types of photographic film to be used as data recording media, the chemicals for processing them, and to receive instructions for processing and duplication of such photographic films. Such samples and instructions shall be provided no later than 30 days after receipt of such a request.

SECTION II. MONITORING OF FILM PROCESSING AND DUPLICATION

1. States Parties taking part in the certification of an observation aircraft and its sensors shall have the right to monitor the processing and duplication of the aerial film used during the in-flight examination. Personnel of the observed and observing Party shall have the right to monitor the processing and duplication of the aerial film used during a demonstration and observation flight.

2. While monitoring the processing and duplication of aerial film, the States Parties shall have the right to bring with them and use, in a manner that does not disrupt the processing or duplication of the film, the following equipment:

(A) litmus papers;

(B) thermometers;

(D) stopwatches;

(E) sensitometers;

(F) densitometers; and

(G) 21-step sensitometric test strips and optical wedges.

3. Prior to the processing of the films exposed during the in-flight examination, demonstration flight and observation flight, States Parties shall check the film processing equipment and chemicals by processing a 21-step sensitometric test strip or exposing and processing a 21-step optical wedge to confirm that the sensitometric data for the processing of that type of film using that film process meets the specifications provided pursuant to Section I of this Annex. Unless otherwise agreed, the original or duplicate aerial film negatives or positives shall not be processed or duplicated until the processing of the 21-step sensitometric test strip or exposing and processing of the 21-step optical wedge meets the characteristics provided in accordance with the provisions of Section I of this Annex for that type of aerial film and film processor or duplicator.

4. Prior to the processing of the films exposed during the in-flight examination, demonstration flight and observation flight, States Parties shall have the right to check the film processing equipment and chemicals by exposing and processing a test film of the same type used during the in-flight examination, demonstration flight and observation flight to confirm that the washing and fixing process is suitable for the purposes of permanent archive storage.
