With respect to holdings of and transactions in securities issued by Ouster,

1.   prepare, execute in the undersigned's name and on the undersigned's behalf,
     and submit to the United States Securities and Exchange Commission (the
     "SEC") a Form ID, including amendments thereto, and any other documents
     necessary or appropriate to obtain and/or regenerate codes and passwords
     enabling the undersigned to make electronic filings with the SEC of reports
     required by Section 16(a) of the Securities Exchange Act of 1934, as
     amended, or any rule or regulation of the SEC;

2.   execute for and on behalf of the undersigned, Forms 3, 4, and 5 in
     accordance with Section 16 of the Securities Exchange Act of 1934, as
     amended, and the rules thereunder;

3.   do and perform any and all acts for and on behalf of the undersigned which
     may be necessary or desirable to complete and execute any such Form 3, 4,
     or 5, complete and execute any amendment or amendments thereto, and timely
     file such form with the SEC and any stock exchange or similar authority;
     and

4.   take any other action of any type whatsoever in connection with the
     foregoing which, in the opinion of such attorney-in-fact, may be of benefit
     to, in the best interest of, or legally required by, the undersigned, it
     being understood that the documents executed by such attorney-in-fact on
     behalf of the undersigned pursuant to this Power of Attorney shall be in
     such form and shall contain such terms and conditions as such attorney-in-
     fact may approve in such attorney-in-facts discretion.

The undersigned hereby grants to each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary, or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or

The undersigned acknowledges that the foregoing attorneys-in-fact, in serving in
