Item 4. Purpose of Transaction.

Item 4 is hereby amended to add the following:

Mr. Sealfon and Dr. Paul M. Baker (“Dr. Baker”), who respectively hold approximately 21% and 5% of the common stock of the Company, requested a special meeting of the shareholders of RMS (the “Special Shareholders’ Meeting”), pursuant to Article II, Section 5 of the Company’s amended and restated by-laws, dated as of October 5, 2016 (the “By-Laws”), and sent the Company notice of the request for the Special Shareholders’ Meeting on August 28, 2018 (the “Notice”), a copy of which is attached as Exhibit 1) to report that Mr. Sealfon and Dr. Baker, who are both members of the Company’s board of directors (the “Board”), further used the Notice to request a special meeting of the Board of RMS (the “Special Board Meeting”), pursuant to Article III, Section 3 of the Company’s By-Laws; and 4) to report that Mr. Sealfon intends to consider all available options to him, with regard to holding, voting, disposing, and acquiring, among other potential actions, his shares of RMS common stock, in light of the subject matters of the Special Shareholders’ Meeting and Special Board Meeting.

At the Special Shareholders’ Meeting, the two matters of business include: 1) the removal of David W. Anderson, Daniel S. Goldberger, Joseph M. Manko, Jr., and Arthur J. Radin as members of the Board; and 2) to vote on new nominees to the Board.  Mr. Sealfon intends to vote to remove all four directors mentioned above, and to vote for replacement directors.

At the Special Board Meeting, the three matters of business include: 1) the removal of Daniel S. Goldberger from all positions with the Company; 2) the removal of Mr. Pettigrew from all positions with the Company; and 3) the nomination and appointment of a new CEO and President of RMS.  Mr. Sealfon intends to vote to remove the individuals mentioned above, and to nominate and vote for the appointment of a new CEO and President.

In light of the foregoing, Mr. Sealfon currently intends to evaluate on an ongoing basis his investments in the Issuer and his options with respect to such investments.  Mr. Sealfon may, for instance, acquire additional shares of common stock for investment and other corporate and strategic purposes if market conditions are favorable, in the open market, in privately negotiated transactions, or otherwise.  Mr. Sealfon may also dispose of some or all of the Issuer’s shares of common stock that he beneficially owns, periodically, by public or private sale (registered or unregistered and with or without the simultaneous sale of newly-issued shares of common stock by the Issuer), gift, expiration of options, forfeiture of restricted shares, or otherwise, including, without limitation, sales of shares of common stock pursuant to Rule 144 under the Securities Act of 1933, as amended, or otherwise.  Mr. Sealfon reserves the right not to acquire shares of common stock at any given time and not to dispose of all or part of his shares of common stock at any given time if he determines such acquisition or disposal is not in his best interest at the time in question.

Other than as described above, Mr. Sealfon does not have any current plans or proposals which relate to, or would result in: (a) any acquisition or disposition of securities of the Company; (b) any extraordinary corporate transaction, such as a merger, reorganization, or liquidation, involving the Issuer or any of its subsidiaries; (c) any sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the Board; (e) any material change in the Issuer’s present capitalization or dividend policy; (f) any other material change in the Issuer’s business or corporate structure; (g) any change in the Issuer’s articles of incorporation or bylaws or other actions which may impede the acquisition of control of the Issuer by any person; (h) causing a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) a class of the Issuer’s equity securities becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934, as amended; or (j) any action similar to those enumerated above.
