The Company has evaluated subsequent events through March 31, 2021, the date the financial statements were issued.
In January 2021, we issued 2,670,121 shares of our common stock pursuant to the terms of our at-the-market offering and Sales Agreement with Ascendiant, as noted in Note 11 above. Aggregate net cash proceeds received totaled $5,058 and transaction costs were $156.
In February 2021, we entered into an underwriting agreement with Northland Securities, Inc. and Roth Capital Partners, LLC, relating to an underwritten public offering to which we issued 11,761,111 shares of our common stock at an offering price of $2.25 per share. Aggregate net proceeds totaled $24,722 and transaction costs were $1,740.
As a result of the fundraising events above, the holder of our 2020 Convertible Notes elected to require us to use forty percent (40%) of the net proceeds satisfy obligations under the 2020 Convertible Notes. The redemption obligation satisfied the full balance of the 2020 Convertible Notes outstanding as of the redemption date, notwithstanding future payments the investor could initiate pursuant to the Investor Note that would further result unrestricted Series B Note principal to be due and outstanding. We paid approximately $11,507, to which $5,541 was to pay the then outstanding principal on the 2020 Senior Convertible Notes, $349 for interest and make-whole and $5,717 to loss on extinguishment of debt. Furthermore, as a result of the underwritten equity raise, the conversion price of the 2020 Convertible Notes decreased from $3.00 to $2.25 per share and the exercise price per share of the warrants decreased from $4.00 per share to $2.25 per share.
In March 2021, the noteholder voluntarily prepaid an aggregate of $10,250 pursuant to the terms of the Investor Note. As a result, we received cash proceeds of $10,250 and this amount of principal of the Series B Note, along with $820 of original issue discount became "unrestricted" and outstanding. After the aforementioned aggregate payments on the Investor Note, there is no unrestricted balance remaining under of the Series B Note.
On March 25, 2021, we delivered a Company Optional Redemption Notice to the holder of our Series B Note exercising our right to redeem and fully satisfy all obligations under the Series B note on April 5, 2021.
On March 16, 2021, we entered into a sublease agreement pursuant to which we will sublease our existing office space in Irvine, California. The term of the sublease commences on April 1, 2021 and terminates on March 31, 2025. The subtenant will pay us base rent in an initial amount of approximately $17 per month, which is subject to certain discounts throughout the lease, as well as rent escalations.
