Slusky, an individual, on November 23, 2015, as amended by Amendment No. 1 to Schedule 13D filed with the SEC on February 8, 2016 (the “Schedule 13D”), is being filed pursuant to Rule 13d-2 of the Securities Exchange Act of 1934, as amended, on behalf of the Reporting Persons to amend and supplement the Schedule 13 D as set forth below to the items indicated. Unless otherwise stated herein, all capitalized terms used in this Amendment No. 2 have the same meanings as those set forth in the Schedule 13D.

Unless specifically amended or supplemented hereby, the disclosures set forth in the Schedule 13D remain unchanged.

Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is amended and supplemented as follows:

The Reporting Persons originally acquired the Shares for investment in the ordinary course of business, as they believed that the Shares, at market prices when acquired, represented an attractive investment opportunity.

The Reporting Persons review their investment in the Company on a continuing basis and have in the past and may in the future engage in discussions with management, the board of directors, other stockholders and other relevant parties concerning the business, operations, board composition, management, strategy and future plans of the Company. The Reporting Persons may also discuss with any of the foregoing parties their views on a potential acquisition of the Company by the Reporting Persons and the potential terms of any such transaction.

On May 21, 2016, the Reporting Persons sent a letter (the “Letter”) to the Company’s board of directors (the “Board”), stating the that (i) the Reporting Persons believe it is time to sell the Company because they have concluded that only as a private company can the Company realize its full potential and (ii) the Reporting Persons propose to enter into negotiations on a non-exclusive basis with the Board to purchase the Company at a market premium price and that they would allow the Board a post-signing “go shop” period to validate that the price offered was the highest obtainable. The foregoing description of the Letter is qualified in its entirety by reference to the Letter, a copy of which is attached hereto as Exhibit 1 and incorporated herein by reference.

Depending on various factors including, without limitation, the results of any such discussions, the Company’s financial position and business strategy, price levels of the Shares, conditions in the securities market and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Company as they deem appropriate including, without limitation, purchasing additional shares or selling some or all of their Shares, engaging in any hedging or similar transactions with respect to the Shares, seeking board representation or taking other action to effect changes in the board composition, ownership structure or operations of the Company, negotiating with the Board the price and terms of an acquisition of the Company, engaging financing sources and professional advisors regarding a potential acquisition, encouraging the Company to pursue one or more other strategic transactions, and/or otherwise changing their intention with respect to any and all matters referred to in Item 4 of Schedule 13D. Except as described above, the Reporting Persons have no present plan or proposals that would relate to or result in any of the matters set forth in subparagraphs (a)-(j) of Item 4 of Schedule 13D.

Exhibit 1

[Letterhead of Vector Capital]

May 21, 2016

Sam Inman

CEO and Chairman of the Board

Covisint Corporation

26533 Evergreen Rd., Suite 500

Southfield, MI 48076

Dear Mr. Inman,

Vector Capital is a leading technology private equity firm with over $2.5 billion of assets under management. We are also Covisint’s second largest shareholder with over 8.5% of the total shares outstanding.

We have noted the recommendations put forth by Roumell Asset Management in its letter dated May 18, 2016, advising that the Board appoint two new independent directors, establish a special committee to review strategic alternatives for the company, and engage a nationally recognized investment banking firm to assist with this review. We agree with Roumell that the time to sell the company is now.

We have followed the Covisint story since its 2013 IPO and engaged extensively with management over much of that time period regarding the company’s operations and prospects. While we are enthusiastic about Covisint’s leading position within the automotive industry and the strength of its core technology, we believe that the potential of these assets can only be realized as a private company with ample growth capital available and the ability to aggressively adapt to the market realities facing you today. We are concerned that poor recent performance, coupled with a history of losses, portend a continuing erosion of shareholder value should the Board endorse a standalone plan for the coming fiscal year.

We are convinced that Vector Capital is in an ideal position to take the company private and provide the growth capital and expertise required to realize the company’s potential, and we are prepared to propose an appropriate market premium to our fellow stockholders in connection with such a transaction. We will work constructively with you, and on an expedited basis, to explore such a Vector take private transaction. We would not require exclusivity for such an investigation, and in order to enable the Board to satisfy its fiduciary obligations, we would agree to a customary post-signing “go shop” period to allow the Company to validate that the market premium received from Vector is the highest attainable.

We eagerly anticipate hearing your response and engaging further with the Company. Please do not hesitate to contact Rob Amen at ramen@vectorcapital.com or at 415-293-5000 with any questions regarding this letter.

Thank you,

/s/ Rob Amen
