ISSUES

1.	Whether the shareholders of Matrix would recognize gain or loss in the Merger.

IV.

OPINION

Based upon our review and subject to: (1) the facts as set forth in paragraph I above, (2) representations as set forth in paragraph II above, (3) the qualifications to, and limitations on, the validity and effectiveness of the Opinion expressed in paragraph VI below, the Firm has the following Opinion:

1.	The Matrix Merger will qualify as a “reorganization” within the meaning of Sec. 368(a) of the Code and as a transaction qualifying for non-recognition of gain and loss under Section 351 of the Code.

2.	The Matrix shareholders will not recognize any gain related to Royale common stock or Royale Series B Convertible Preferred Stock received in exchange for their shares of Matrix Stock.

3.	The tax basis of the Royale stock received by each Matrix shareholder will equal the tax basis of such stockholder’s Matrix stock surrendered in the Merger; and

The holding period of the Royale stock received by the Matrix shareholders will include the holding period during which the Matrix stock was held at the time of the Merger, provided that such stock was held as a capital asset in the hands of the Matrix shareholder on the date of the Merger under Section 1223(1).

Nevertheless, as a result of the debt issued by the Matrix LPs Revenue Ruling 84‑11, 1984-2 C.B 88, provides that certain provisions of the Code which address the assignment or assumption of the debt of a partnership would come into play to treat the transaction as if cash were distributed to the limited partners. Section 752(d) of the Code provides that in the case of a sale or exchange of an interest in a partnership, liabilities shall be treated in the same manner as liabilities in connection with the sale or exchange of property not associated with partnerships.

Section 358(d) of the Code provides that where a taxpayer transfer’s property to a new corporation, and the transferee corporation assumes the liability, the transferor is treated as having received money on the exchange in the amount of debt relieved.

Section 351(b) provides that where the transferor receives cash, as described above, in the addition to stock of the new corporation, gain shall be recognized but not in excess of the cash received, and any loss shall not be recognized. If the fair market value of the stock of Royale and cash received by a limited partner exceeds the tax basis such limited partner had in its limited partnership interests, then gain shall be recognized, but not in excess of the amount of his or her allocable share of cash received (debt transferred). Assuming the property would qualify as a capital asset or as Section 1231 property, the gain should be long term capital gain if the owner held the partnership interest for 12 months or more except for any gain recaptured as ordinary income under Section 1254 of the Code such as recapture of previously deducted “intangible dripping costs.” The tax basis of the Royale stock received by a limited partner will equal the tax basis of the limited partnership interests exchanged, less the allocable portion of the Matrix LP’s debt assumed by Royale, plus any gain recognized. Under Section 1223(1) of the Code, the holding period of the Royale stock received by the former partners include the respective partner’s holding period for the partnership interest transferred, except that the holding period for the Royale stock received in exchange for Section 751 assets of the Matrix LPs that are neither capital assets nor Section 1231 assets begins on the day following the date of exchange.

V.	LAW AND ANALYSIS

A.	Non Recognition of Gain or Loss

1.	Section 351

No gain or loss is recognized if property is transferred to a corporation by one or more persons solely in exchange for stock in such corporation and immediately after the exchange such person or persons are in control (as defined by Section 368(c) of the corporation.

The Matrix shareholders will be transferring the assets of Matrix to Matrix Merger Sub in return for stock of Matrix Merger Sub and, immediately after the transfer will own control of Matrix Merger Sub. Therefore, the transfer of the assets to Matrix Merger Sub in return for its stock will not result in recognition of gain or loss.

2.	Section 354

Section 354(a)(1) provides that no gain or loss is recognized if stock in a corporation which is a party to a reorganization is, in pursuance to the plan of reorganization, exchanged solely for stock in such corporation or in another corporation which is a party to the reorganization. Section 368(b)

defines the term “a party to a reorganization” to include a corporation resulting from a reorganization or both corporations, in the case of a reorganization resulting from the acquisition by one corporation of stock or properties of another. Thus, Matrix shareholders will recognize no gain or loss on the exchange of their Matrix stock for the stock of Royale.

3.	Section 361

Section 361(a) provides that no gain or loss will be recognized to a transferor corporation which is a party to a reorganization on any exchange pursuant to the plan or reorganization solely for stock or securities in another corporation which is a party to the reorganization. Therefore, Matrix will not recognize gain or loss upon the transfer of its assets to Royale in exchange for the stock of Royale.

4.	Section 358

Section 358(a)(i) provides that in the case of an exchange to which Section 354 applies, the basis of the property permitted to be received without the recognition of gain or loss is the same as that if the property exchanged. Thus the basis of the Royale stock to be received by the shareholders of Matrix will be, in each instance, the same as the basis of their stock surrendered in the exchange.

5.	Section 1223

Section 1223(1) states that in determining the period for which a taxpayer has held property received in an exchange, the period for which the taxpayer held the property exchanged is included if the property has, for the purpose of determining gain or loss from a sale or exchange, the same basis in whole or in part in the taxpayer’s hands the property exchanged, and the property exchanged constitutes a capital asset at the time of the exchange.

Section 1223(2) provides that in determining a taxpayers holding period for property, there is included the period for which such property was held by another person, if such property has, for the purpose of determining gain or loss from a sale or exchange, the same basis in whole or in part on the taxpayer’s hands as it had in the hands of another person.

Therefore, the holding period of the Royale stock to be received by the shareholders of Matrix stock in the transaction will include, in each instance, the period during which the Matrix stock surrendered in the exchange, is held as a capital asset on the date of the surrender.
