Item 3. Source and Amount of Funds or Other Consideration

Merger Agreement

On November 8, 2012, Issuer, Sun Pharma and Purchaser entered into an Agreement and Plan of Merger (the “Merger Agreement”) pursuant to which Purchaser agreed to commence a tender offer (the “Offer”) to acquire all of the outstanding Shares, at a purchase price of $8.00 per Share (the “Offer Price”), net to the tendering shareholder in cash, without interest and less any required withholding taxes, subject to the satisfaction or waiver of the conditions to the Offer set forth in the Merger Agreement. Upon successful completion of the Offer, and subject to the terms and conditions of the Merger Agreement, Purchaser will merge with and into Issuer (the “Merger”), and Issuer will survive the Merger as a wholly owned indirect subsidiary of Sun Pharma (the “Surviving Corporation”).

On November 16, 2012, Sun Pharma assigned the Merger Agreement and all of its rights and obligations therein to the Parent. Pursuant to the terms of the Merger Agreement, notwithstanding the assignment, Sun Pharma is not relieved of any liability or obligation under the Merger Agreement.

The transactions are expected to be completed by year end 2012. The consummation of the Offer and Merger are subject to various closing conditions, including the tender of a majority of the Shares, the expiration of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other customary conditions. The Offer is not subject to a financing condition. The Merger Agreement also includes customary termination provisions for both the Issuer and the Parent and provides that, in connection with the termination of the Merger Agreement under specified circumstances, the Issuer will be required to pay Parent a termination fee of $9,000,000.

In the Merger Agreement, Issuer has granted to Purchaser an irrevocable option (the “Top-Up Option”) exercisable only in accordance with the terms and subject to the conditions set forth in the Merger Agreement, to purchase at a price per Share equal to the Offer Price, that number of newly issued Shares equal to the lowest number of Shares, that when added to the number of Shares collectively owned by the Parent or Purchaser at the time of such exercise, constitutes one Share more than 90% of the sum of the then outstanding Shares. The maximum number of Shares issuable pursuant to the Top-Up Option is equal to the maximum number of Shares authorized and unissued or held in the treasury of Issuer. The Reporting Persons disclaim beneficial ownership of these Shares.

The foregoing summary description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement listed as Exhibit 2.1 hereto, which is hereby incorporated herein by reference.

Support Agreements

Concurrently with the execution and delivery of the Merger Agreement, and as a condition and inducement to Sun Pharma’s willingness to enter into the Merger Agreement, Sun Pharma and Purchaser entered into a Support Agreement (the “Support Agreements”) dated as of the date of the Merger Agreement with the directors and executive officers of the Issuer (each a “Supporting Shareholder”). The purpose of the Support Agreements is to facilitate the consummation of the transactions contemplated by the Merger Agreement. The Supporting Shareholders own an aggregate of 4,464,746 Shares representing approximately 15.6% of the 25,027,683 Shares outstanding as of November 8, 2012 (as represented by Issuer in the Merger Agreement), 2,053,650 options to purchase Issuer common stock, and 1,549,000 restricted shares beneficially owned by the Supporting Shareholders. None of the Supporting Shareholders were paid any additional consideration in connection with entering into the Support Agreements.

On November 16, 2012, Sun Pharma assigned the Support Agreements and all of its rights and obligations therein to the Parent. Pursuant to the terms of the Support Agreements, notwithstanding the assignment, Sun Pharma is not relieved of any liability or obligation under the Merger Agreement.

The names of the Supporting Shareholders and the number of Shares and the percentage ownership that are subject to the Support Agreements are set forth in Schedule B hereto which is hereby incorporated herein by reference. The foregoing summary description of the Support Agreements does not purport to be complete and is qualified in its entirety by reference to the form of Support Agreement listed as Exhibit 2.2 hereto, which is hereby incorporated herein by reference.

Pursuant to the Support Agreements, each of the Supporting Shareholders, among other things, agrees to tender all of their Shares, including any additional Shares acquired prior to the Effective Time of the Merger (as defined in the Merger Agreement) or the termination of the Merger Agreement in accordance with its terms, in the Offer as promptly as practicable after commencement of the Offer (and in any event on or before the 10th business day thereafter), and not to withdraw such Shares from the Offer unless the applicable Support Agreement is terminated or, without the consent of the Issuer, the Purchaser amends the Offer to reduce the offer price, reduce the number of Shares subject to the Offer, change the form of consideration payable in the Offer, or amends or modifies a term or condition of the Offer or Merger Agreement that is adverse to any shareholder of the Issuer.

The Supporting Shareholders also, among other things, agree to vote (a) in favor of adoption of (1) the Merger Agreement and all the other transactions contemplated by the Merger Agreement, including the Merger, and (2) any other matter that is required to facilitate the consummation of the other transactions contemplated by the Merger Agreement; and (b) against (1) any Takeover Proposal and any agreement or arrangement related to such Takeover Proposal, and (2) any action or agreement that would impair the ability of Parent and the Purchaser to complete the Offer or the Merger, or the ability of the Company to consummate the Merger, in any material respect or that would otherwise be inconsistent with or prevent, impede or delay the consummation of the transactions contemplated by the Merger Agreement in any material respect. The Supporting Shareholders grant an irrevocable proxy appointing Parent and any designee of Parent as such Supporting Shareholder’s attorney-in-fact and proxy to vote with respect to the Merger and related matters. The Supporting Shareholders agree, subject to certain exceptions, not to (a) transfer their Shares that are subject to the Support Agreement, (b) grant any proxies or powers of attorney, deposit any Shares into a voting trust or enter into a voting agreement with respect to any Shares, (c) take any action that would cause any representation or warranty of the Supporting Shareholder to become untrue or incorrect or have the effect of preventing or disabling the Supporting Shareholder from performing his or her obligations thereunder; or (d) commit or agree to take any of the foregoing actions. Other than with respect to the matters described in, and subject to the limitations set forth in, the Support Agreements, Parent and Purchaser do not have the right to vote or direct the vote of, or to dispose or to direct the disposition of, any of the Shares subject thereto.

The Support Agreements will terminate upon the earliest of (a) the Effective Time, (b) the mutual written agreement of the parties thereto, (c) the termination of the Merger Agreement in accordance with its terms, (d) a Company Adverse Recommendation Change (as defined in the Merger Agreement) and (e) the occurrence of any of the events permitting a Supporting Shareholder to decline to tender or withdraw its Shares.

Item 4. Purpose of Transaction

As described in Item 3 above, this Schedule 13D relates to the Offer, the Merger, the Support Agreements and the Top-Up Option, the purpose of which are to assist the Parent and Purchaser acquiring control of, and ultimately, the entire equity interest in Issuer.

Upon completion of the Offer, Purchaser has the right to designate a number of directors on Issuer’s board of directors (and each committee of Issuer’s board of directors and the boards of directors and each board committee of its subsidiaries) that will give Purchaser representation on such boards of directors and committees proportional to the number of Shares purchased by Purchaser as compared to the number of Shares outstanding. The Issuer has agreed to take all actions reasonably necessary to seek and accept the resignations of incumbent directors to provide Purchaser with this level of representation, and to cause the designees of Purchaser to be elected.

Upon the consummation of the Merger, (i) the Surviving Corporation will become a wholly owned direct subsidiary of the Parent and indirect wholly owned subsidiary of Sun Pharma and (ii) each outstanding share of Issuer’s common stock (other than Shares held in the treasury of Seller or owned by Parent or Purchaser) will be converted into the right to receive the Offer Price. The directors of Purchaser immediately prior to the effective time of the Merger will be the directors of the Surviving Corporation, each to hold office in accordance with the articles of incorporation and bylaws of the Surviving Corporation. The officers of Issuer immediately prior to the effective time of the Merger will be the officers of the Surviving Corporation, until their respective successors are duly elected or appointed and

qualified or until their earlier death, resignation or removal. The officer and director of Purchaser was appointed by Parent and is identified in Schedule A.

At the Effective Time, the certificate of incorporation of DUSA will be amended as provided in the Merger Agreement, and as so amended, will be the certificate of incorporation of the Surviving Corporation. Furthermore, at the Effective Time, the bylaws of the Surviving Corporation will be amended to be identical to the bylaws of the Purchaser, as in effect immediately prior to the Effective Time.

Following the Merger, the Issuer will not continue to be publicly traded, and the registration of the Shares under the Exchange Act will be terminated. The foregoing summary description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement listed as Exhibit 2.1 hereto, which is hereby incorporated herein by reference.

Except as set forth in this Schedule 13D and in connection with the Offer and the Merger described above, the Reporting Persons have no plans or proposals that relate to or would result in any of the transactions described in subparagraphs (a) through (j) of Item 4 of Schedule 13D. Parent intends to continue reviewing Issuer’s assets, corporate structure, dividend policy, capitalization, operations, properties, policies, management and personnel as part of a comprehensive review with a view to optimizing development of Issuer’s potential in conjunction with Sun Pharma’s existing business. This planning process will continue throughout the pendency of the Offer and the Merger.

Item 5. Interests in Securities of the Issuer

(a) - (b) As a result of the Support Agreements, the Reporting Persons may be deemed to have shared voting power and shared dispositive power with respect to 4,464,746 Shares, subject to the conditions and limitations of the Support Agreements, and thus, for the purpose of Rule 13d-3 promulgated under the Exchange Act, the Reporting Persons may be deemed to be the beneficial owners of an aggregate of 4,464,746 Shares. All Shares that may be deemed to be beneficially owned by the Reporting Persons constitute approximately 15.6% of the issued and outstanding Shares as of November 8, 2012 (as represented by Issuer in the Merger Agreement) and including the number of outstanding options to purchase Issuer common stock held by the Supporting Shareholders and restricted shares beneficially owned by the Supporting Shareholders.

In the event Purchaser exercises the Top-Up Option described in Item 3 above, the Reporting Persons will have sole voting power and sole dispositive power over the Shares issued upon exercise.

The Reporting Persons (i) are not entitled to any rights as a shareholder of Issuer as to the Shares covered by the Support Agreements, except as otherwise expressly provided in the Support Agreements, or as to the Shares subject to the Top-Up Option, and (ii) disclaim all beneficial ownership of such Shares.

Except as set forth in this Item 5, none of the Reporting Persons, or, to the knowledge of the Reporting Persons, any persons named in Schedule A, beneficially owns any Shares.

(c) Except for the agreements described above, none of the Reporting Persons, or, to the knowledge of the Reporting Persons, any persons named in Schedule A, has effected any transaction in securities of Issuer reported herein during the past 60 days.

(d) To the knowledge of the Reporting Persons, no other person has the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the securities of Issuer reported herein.

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer
