POWER OF ATTORNEY
(For Executing Form ID and Forms 3, 4 and 5)

Know all by these presents that the undersigned hereby constitutes and appoints
each of Div Gupta and Alison Haggerty of Cooley LLP, signing individually, the
undersigned's true and lawful attorney-in-fact and agents to:

(1)	Prepare, execute in the undersigned's name and on the undersigned's behalf,
and submit to the Securities and Exchange Commission (the "SEC") a Form ID,
including amendments thereto, and any other documents necessary or appropriate
to obtain 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 (the "Exchange Act"), or any rule or regulation
thereunder;

(2)	Prepare, execute in the undersigned's name and on the undersigned's behalf,
and submit to the SEC Forms 3, 4 and 5 (including amendments thereto and joint
filing agreements in connection therewith) in accordance with Section 16(a) of
the Exchange Act and the rules thereunder;

(3)	Do and perform any and all acts for and on behalf of the undersigned that
may be necessary or desirable to prepare, complete and execute any such Form 3,
4 or 5 (including amendments thereto and joint filing agreements in connection
therewith) and timely file such forms with the SEC and any stock exchange,
self-regulatory association or any other authority; and

(4)	Take any other action of any type whatsoever in connection with the
foregoing that, in the opinion of any such attorney-in-fact, may be necessary or
desirable in connection with the foregoing authority, it being understood that
the documents executed by any 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 the attorney-in-fact may approve in the
attorney-in-fact's 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
could do if personally present, with full power of substitution or revocation,
hereby ratifying and confirming all that such attorney-in-fact, or such
attorney-in- fact's substitute or substitutes, shall lawfully do or cause to be
done by virtue of this Power of Attorney and the rights and powers herein
granted.  The undersigned acknowledges that the foregoing attorneys-in-fact, and
their substitutes, in serving in such capacity at the request of the
undersigned, are not assuming any of the undersigned's responsibilities to
comply with Section 16 of the Exchange Act.

This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4 and 5, unless earlier
revoked by the undersigned in a signed writing delivered to the
attorneys-in-fact or, as to any attorney-in-fact individually, such
attorney-in-fact is no longer affiliated with Cooley LLP, as applicable.  This
Power of Attorney revokes any other power of attorney that the undersigned has
previously granted to representatives of Cooley LLP.  This Power of Attorney may
be filed with the SEC as a confirming statement of the authority granted herein.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of the date written below.
