Explanatory Note

This Amendment No. 16 to Schedule 13D (this “Amendment No. 16”) is being filed with respect to the beneficial ownership of common stock, par value $0.0001 per share (the “Common Stock”), of Juma Technology Corp., a Delaware corporation (the “Issuer” or the “Company”). This Amendment No. 16 supplements Items 3, 4 and 7, and amends and restates in its entirety Item 5, of the Schedule 13D (as amended) originally filed on October 19, 2009.

ITEM 3.

Source and Amount of Funds or Other Consideration

The funds used to acquire the securities described in Item 4 of this Amendment No. 16 were from working capital of the Master Fund, and the amount of funds totaled in the aggregate $180,000.

ITEM 4.

Purpose of Transaction.

May 13, 2011 Note and Warrant Purchase Agreement

On May 13, 2011, the Issuer entered into a Note and Warrant Purchase Agreement (the “Purchase Agreement”) with the Master Fund. Under the Purchase Agreement, the Issuer executed and delivered to the Master Fund (a) a 10% bridge note in the aggregate principal amount of $180,000 (the “Note”) and (b) a Series A Warrant to purchase an aggregate of 1,200,000 shares of the Issuer’s common stock (the “Warrant”). The principal amount of the Note is payable within five (5) days after demand. The Note accrues interest at 10% per annum from the date of issuance, which interest is payable in cash within five (5) days after demand. The Note does not contain any conversion provisions. The Warrant is exercisable into shares of Common Stock at any time at the option of the Master Fund at an initial exercise price of $0.15 per share, provided that it cannot be exercised or converted to the extent that after giving effect thereto the beneficial ownership of the Master Fund, VCAF and their affiliates would exceed 4.99% of the Issuer’s outstanding Common Stock (which restriction can be lifted upon 61 days notice). The term of the Warrant expires March 31, 2015.

Waiver of Price Protection

Concurrently with the above described Purchase Agreement, the Company has entered into an Acknowledgement and Waiver of Anti-Dilution Adjustments (the “Acknowledgement”). Under the Acknowledgement, the Company acknowledged that the price protection provisions of the Series B Preferred Stock were triggered; provided, however, that the Master Fund and VCAF agreed to waive the price protections of the Series B Preferred Stock.

ITEM 5.

Interest in Securities of the Issuer.

(a) The Master Fund and VCAF, collectively, (i) own 1,116,705 shares of Common Stock, (ii) have the ability to acquire an additional 221,795,434 shares of Common Stock through the exercise or conversion of derivative securities and (iii) thus beneficially own 222,912,139 shares of Common Stock, representing 83.1% of all of the Issuer’s outstanding Common Stock. The Investment Manager and Mr. Benowitz (and the General Partner with respect to the shares of Common Stock owned by VCAF) may each be deemed to beneficially own the shares of Common Stock beneficially owned by the Master Fund and VCAF. Each disclaims beneficial ownership of such shares. The foregoing is based on 46,468,945 shares of Common Stock outstanding as of March 24, 2011, as reported on the Issuer’s Form 10-K filed on March 30, 2011.

Page 7 of 10 pages

(b) The Reporting Persons have shared power (with each other and not with any third party), to vote or direct the vote of and to dispose or direct the disposition of the 222,912,139 shares of Common Stock reported herein.

(c) Except as provided in Item 4, no transactions in the Common Stock have been effected by the Reporting Persons or, to the knowledge of the Reporting Persons, the Directors and Officers, since the filing of Amendment No. 15 to Schedule 13D on May 16, 2011.

(d) Not applicable.
