UDS CAPITAL I /s/ STEVE BLANK Steve Blank, as Regular Trustee CERTIFICATE OF AUTHENTICATION This is the Trust Preferred Security described in the within-mentioned Declaration. THE BANK OF NEW YORK, as Trustee By: /s/ WALTER GITLIN, Vice President Authorized Signatory Dated: June 25, 1997 (See reverse for additional terms) <PAGE/> [REVERSE OF SECURITY] Holders of Trust Preferred Securities shall be entitled to receive cumulative cash distributions at a rate per annum of 8.32% of the stated liquidation amount of $25 per Trust Preferred Security. Distributions on the Trust Preferred Securities shall, from the date of original issue, accumulate and be cumulative and shall be payable quarterly only to the extent that the Trust has funds available for the payment of such distributions in the Property Account. Distributions not paid on the scheduled payment date will accumulate and compound quarterly (to the extent permitted by applicable law) at the rate of 8.32% per annum. The term "Distributions" as used herein shall mean ordinary cumulative distributions in respect of each Fiscal Period together with any such Compounded Distributions. Amounts available to the Trust for distribu- tion to the holders of the Trust Preferred Securities will be limited to payments received by the Trust from the Partnership on the Partnership Preferred Securities or from the Company on the Partnership Guarantee. Distributions on the Partnership Preferred Securities will be paid only if, as and when declared in the sole discretion of the Company, as the General Partner of the Partnership. If and to the extent that the Part- nership makes a distribution on the Partnership Preferred Securities held by the Property Trustee or the Company makes a payment under the Partnership Guarantee (the amount of any such partnership distribution, including any compounded partnership distributions or guarantee payment being a "Payment Amount"), the Trust shall and the Property Trustee is directed, to the extent funds are available for that purpose, to make a Pro Rata Distribution of the Payment Amount to Holders. The amount of Distributions payable for any period will be computed for any full quarterly Distribution period on the basis of a 360-day year of twelve 30-day months, and for any period shorter than a full quarterly Distribution period on the basis of the actual number of days elapsed in a 90-day quarter. Except as otherwise described herein, distributions on the Trust Preferred Securities will be cumulative, will accumulate from the date of initial issuance and will be payable quarterly in arrears, on March 31, June 30, September 30 and December 31 of each year, commencing on June 30, 1997, if, as and when available for payment by the Property Trustee. If the Trust Preferred Securities (or, if the Trust is liquidated, the Partnership Preferred Securities) are in book-entry-only form, Distributions will be payable to the Holders of record of Trust Preferred Securities as they appear on the books and records of the Trust on the relevant record dates, which will be one Business Day prior to the relevant payment dates. If the Trust Preferred Securities (or, if the Trust is liquidated, the Partnership Preferred Securities) do not remain in book-entry-only form, the relevant record dates shall be the 15th day of the month of the relevant payment dates. In the event that any date on which distributions are payable is not a Business Day, payment of such Distribution shall be made on the next succeeding day which is a Business Day (without any interest or other payment in respect of any such delay) except that, if such Business Day falls in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, with the same force and effect as if made on such date. Payments of accumulated Distributions will be payable to Holders of record of Trust Preferred Securities as they appear on the books and records of the Trust on the record date with re- spect to the payment date for the Trust Preferred Securities which corresponds to the payment date fixed by the Partnership with respect to the payment of cumulative distributions on the Partnership Preferred Securities. The Trust Preferred Securities shall be redeemable as provided in the Declaration. <PAGE/> ASSIGNMENT FOR VALUE RECEIVED, the undersigned assigns and transfers this Trust Preferred Security Certificate to: (Insert assignee's social security or tax identification number) (Insert address and zip code of assignee) and irrevocably appoints agent to transfer this Trust Preferred Security Certificate on the books of the Trust.
