SPX will also assume or refinance $876 million in United Dominion debt, bringing the total transaction value to $1.83 billion. The Board of Directors of both companies unanimously approved the agreement. United Dominion shareholders will receive SPX shares based on a fixed exchange ratio of 0.2353 of an SPX share per United Dominion share, or $25 per United Dominion share based on the average closing price of a share of SPX common stock for the five-day period ended Friday, March 9, 2001. There is no collar on the fixed exchange ratio. The purchase price represents an approximate 30% premium for United Dominion shareholders, based on the same five-day period. With this transaction, SPX is creating an even stronger, multi-industry company with approximately $5 billion in pro forma annual revenues and enhanced value-creation opportunities. SPX also will gain additional international reach as United Dominion derives approximately 33% of its earnings from sources outside the United States. United Dominion, a diversified manufacturer of proprietary engineered products, brings to SPX 18 businesses, many of which -more-

2 -2- have leading market shares or product lines in key areas that fit well into the SPX model. SPX will incorporate United Dominion's businesses into four business segments -- flow technology, industrial products and services, technical products and systems, and service solutions. SPX will use cash on hand and a new $780 million bank credit facility underwritten by JP Morgan, a division of Chase Securities to refinance United Dominion's existing debt. The taxable transaction, which is to be implemented as a court-approved plan of arrangement (similar to a merger) under Canadian corporate law, is subject to approval by UDI shareholders, antitrust clearance and customary closing conditions, and is expected to close in the second quarter of 2001. If the merger agreement is terminated in certain circumstances, United Dominion will be required to pay SPX a break-up fee of $40 million. United Dominion will delay its currently scheduled annual meeting and intends to hold a combined annual and special meeting to vote on the merger agreement. SPX expects the acquisition to be accretive to its earnings per share in the first full year and to produce significant incremental cash flow, based on achieving cost savings of at least $30 million in the first full year. SPX plans to implement its Value Improvement Process(R) and Economic Value Added-based (EVA(R)) compensation programs in United Dominion's 18 businesses. SPX Chairman, President and CEO John B. Blystone said, "This is a superb acquisition which broadens and strengthens SPX's portfolio of industrial and technical businesses and provides us with enhanced value-creation opportunities. Shareholders of both companies will benefit from this transaction, which provides us with greater critical mass and a larger platform for increasing shareholder wealth. United Dominion shareholders will receive a significant premium for their shares and participation in the value we will build at the combined company. Our shareholders will benefit from these excellent assets that fit well with our existing businesses at an attractive EBITDA multiple. We look forward to replicating the success of the General Signal acquisition on a larger scale." William W. Stinson, United Dominion's Management Committee Chairman, stated, "SPX is a leading multi-industry company with a strong track record of growing and integrating diversified businesses and returning exceptional value to its shareholders. United Dominion shareholders will own 23% of an expanded SPX with tremendous upside potential. I am excited that our shareholders and employees are becoming part of the SPX family." Blystone added, "Just as we did with General Signal and its diverse portfolio, we will use our proven program of incentivizing management and implementing cost-cutting initiatives, operational improvements and strategic divestitures to successfully integrate United Dominion's -more-

3 -3- businesses into SPX. We will work to eliminate duplicate corporate costs, achieve operating efficiencies, enhance productivity, extend EVA-based compensation, invest in technology and improve customer quality and service. We're confident that we can utilize our leadership experience and management techniques and leverage our technological expertise to achieve superior growth and profitability for the combined company." Blystone concluded, "We look forward to working with the many talented people at United Dominion. Upon completion of the transaction, SPX will have annual revenues of more than $5 billion, four powerful business segments, strong cash flow, expanded global reach and even greater opportunities for growth and value creation." SPX's plan to improve performance at United Dominion will be patterned after SPX's own turnaround. Since late 1995, the company has met or exceeded analyst consensus estimates for 20 consecutive quarters, operating margins have tripled and the stock price has increased seven-fold. In addition, more than 70% of SPX employees have compensation tied to improvement in EVA. SPX was advised by JP Morgan; Fried, Frank, Harris, Shriver & Jacobson; and Fasken, Martineau DuMoulin LLP. United Dominion was advised by BMO Nesbitt Burns; Stikeman Elliott; and Robinson, Bradshaw & Hinson P.A. United Dominion is a diversified manufacturer of proprietary engineered products in four business segments -- Flow Technology, Machinery, Specialty Engineered Products, and Test Instrumentation. It has annual sales of $2.4 billion and 14,000 employees in 20 countries. More information is available at http://www.uniteddominion.com.

ARTICLE 7 COVENANTS OF UDI SECTION 7.1 NO SOLICITATION.

Any such notice to SPX shall be made orally immediately following any such receipt or request, shall be confirmed in writing, and shall indicate the details of the Acquisition Proposal or request for information or access known to such Persons, including the specific terms of, and the identity of the Third Party making, such Acquisition Proposal or request.

32 such proposal could reasonably be expected to lead to a Superior Acquisition Proposal, and (after consultation with and receipt of advice from its outside legal counsel) that failure to take such action would constitute a breach of the fiduciary duties of UDI's Board of Directors under applicable Law. (4) If, prior to the receipt of the UDI Shareholders Approval, the Board of Directors of UDI determines in good faith (based upon the written advice of UDI's independent financial advisor and the advice of its outside legal counsel) by a vote of a majority of the total number of directors then in office, with respect to any bona fide written proposal from a Third Party for an Acquisition Proposal received after the date hereof and prior to the date of the UDI Meeting that was not solicited, initiated, encouraged or facilitated by UDI, directly or indirectly, after the date of this Agreement or otherwise resulted from a breach of this Section 7.1, that such Acquisition Proposal is a Superior Acquisition Proposal and is in the best interest of UDI and its shareholders and failure to enter into such Acquisition Proposal would constitute a breach of the fiduciary duties of the Board of Directors of UDI under applicable Law, then UDI may terminate this Agreement and enter into an acquisition agreement for the Superior Acquisition Proposal; provided that, prior to any such termination, and in order for such termination to be effective, (i) UDI shall provide SPX two Business Days' written notice that it intends to terminate this Agreement pursuant to this Section 7.1(4), identifying the Superior Acquisition Proposal and the parties thereto and delivering an accurate description of all material terms of the Superior Acquisition Proposal to be entered into, and (ii) on the date of termination (provided that the advice of the independent financial advisor and outside legal counsel referred to above shall continue in effect without revocation, revision or modification), UDI shall deliver to SPX (A) a written notice of termination of this Agreement pursuant to this Section 7.1(4), (B) a wire transfer of immediately available funds in the amount of the Termination Fee, (C) a written acknowledgement from UDI that the termination of this Agreement and the entry into the Superior Acquisition Proposal are a Triggering Event, and (D) a written acknowledgement from each other party to the Superior Acquisition Proposal that it has read UDI's acknowledgement referred to in clause (C) above and will not contest the matters thus acknowledged by UDI, including the payment of the Termination Fee.

33 ARTICLE 8 COVENANTS OF SPX SECTION 8.1 COVENANTS OF SPX.

SECTION 8.2 EMPLOYMENT AGREEMENT. SPX acknowledges the existence of the Change in Control Payment Obligations and Retention Payment Obligations listed in Section E.16(k) of the UDI Disclosure Letter (and which UDI represents and warrants are the only Change in Control Payment Obligations and Retention Payment Obligations required to be listed in Section E.16(k) of the UDI Disclosure Letter), and SPX agrees, after the Effective Time, to cause Amalco or any successor thereto to honour and comply with the terms of those (but only those) Change in Control Payment Obligations and Retention Payment Obligations that are so listed. 28

34 SECTION 8.3 OFFICERS AND DIRECTORS INSURANCE. SPX agrees to use commercially reasonable efforts to secure directors and officers liability insurance coverage for UDI's current and former directors and officers on a six (6) year "trailing" or "runoff" basis from and after the Effective Time; provided, however, if a "trailing" policy is not available, then SPX agrees that for the entire period from the Effective Time until six (6) years after the Effective Time, SPX will cause Amalco or any successor thereto to maintain UDI's current directors' and officers' insurance policy or an equivalent policy; and provided, further, that in no event shall SPX be required to expend pursuant to this Section 8.3 more than an amount per year equal to 200% of current annual premiums paid by UDI and its subsidiaries for such insurance. In either case (but subject to the foregoing proviso limiting the amount required to be expended) such insurance shall be on terms and conditions no less advantageous to the directors and officers of UDI than those contained in the policy in effect on the date hereof and shall cover all present and former directors and officers of UDI for claims made prior to or within six (6) years after the Effective Time. The provisions of this Section 8.3 are intended to be for the benefit of, and will be enforceable by, each indemnified party, his or her heirs and his or her representatives, and are in addition to, and not in substitution for, any rights to indemnification or contribution or cause of action that any such Persons may have by contract or otherwise. SECTION 8.4 INDEMNITIES. SPX agrees that from and after the Effective Time it shall cause Amalco and its subsidiaries to fulfill their respective obligations pursuant to indemnities provided or available to past and present officers and directors of UDI and its subsidiaries pursuant to the provisions of the UDI Governing Documents, or articles of incorporation, bylaws and other organizational documents of subsidiaries of UDI, as the case may be, the CBCA or corporate statutes and equivalent Laws of the jurisdiction of incorporation of subsidiaries of UDI, as the case may be, and any written indemnity agreements entered into between UDI and its officers and directors (collectively the "INDEMNITY RIGHTS"). Such obligations shall continue in full force and effect (and the UDI Governing Documents, articles of incorporation, bylaws and other organizational documents of subsidiaries of UDI and the written indemnity agreements shall not be amended or modified to reduce such obligations in any respect) for a period of six (6) years from the Effective Time. In addition, SPX agrees to indemnify the directors of UDI for any liability they may incur as a result of the performance of their obligations under Section 2.1(1)(g) to the extent such liability is not covered by any directors and officers liability insurance policy or under any of the Indemnity Rights. The provisions of this Section 8.4 are intended to be for the benefit of, and will be enforceable by, each indemnified party, his or her heirs and his or her representatives, and are in addition to, and not in substitution for, any rights to indemnification or contribution or cause of action that any such Persons may have by contract or otherwise. Nothing herein shall limit the right of SPX to cause UDI or any of 29

35 its subsidiaries to be amalgamated or merged into or otherwise combined with any other entity. SECTION 8.5 COMPENSATION; BENEFIT PLANS. SPX agrees to cause Amalco or any successor thereto to maintain, for a period of at least one year from the Effective Date, salaries and bonus award opportunities or other incentive compensation opportunities (other than stock options, restricted stock awards or any other equity-based awards or plans), profit sharing or deferred compensation at levels which for each active employee of UDI or any of its subsidiaries at the Effective Time (the "AFFECTED EMPLOYEES"), including members of management of UDI or any of its subsidiaries, are comparable in the aggregate (after taking into account benefits that may be provided to such employee under any employee benefit plan of SPX) either (i) to those currently applicable to such Affected Employee or (ii) to those provided to similarly situated employees of SPX from time to time (other than benefits provided under the SPX Individual Account Retirement Plan). SPX further agrees to cause Amalco and any successor to Amalco to maintain, for a period of at least one year from the Effective Date, all UDI Benefit Plans which are employee welfare benefit plans within the meaning of Section 3(1) of ERISA currently available to Affected Employees or to make available alternative employee welfare benefit plans which take into account, for purposes of eligibility and vesting thereunder, the past service of Affected Employees to the same extent such service is credited under comparable UDI Benefit Plans, so as to provide an Affected Employee employee welfare benefits which are comparable in the aggregate either (i) to those employee welfare benefits currently provided under such UDI Benefit Plans to such Affected Employee or (ii) to those employee welfare benefits provided to similarly situated employees of SPX from time to time. Without limiting the generality of the foregoing, with respect to the employee welfare benefits provided by SPX, (i) Affected Employees shall be credited as at the Effective Time under the employee welfare benefit plans of SPX for service with UDI to the extent such service was credited under the UDI Benefit Plans for purposes of satisfying waiting periods related to eligibility to participate and (ii) SPX shall waive any pre-existing conditions exclusion for any Affected Employee to the extent such exclusion was not applicable to such Affected Employee under the UDI Benefit Plans. To the extent Affected Employees commence participation in employee welfare benefit plans of SPX other than on the first day of a plan year, such Affected Employees shall be credited under the employee welfare benefit plans of SPX for amounts expended by such Affected Employee for such plan year under UDI's employee welfare benefit plans in satisfaction of co-pay, deductible and other stop-loss provisions of UDI's employee welfare benefit plans. Nothing in this Agreement shall be construed to prevent the termination of employment of any employee or any amendment or termination of any UDI Benefit Plan to the extent permitted by the terms and conditions thereof as in effect on the date hereof. 30

59 completion of the steps contemplated by Sections 2.2(a) through (i) hereof, other than MergeCo, in respect of each such outstanding UDI Common Share, a fraction of one fully paid and non-assessable Amalco Special Share the numerator of which is one (1) and the denominator of which is equal to the aggregate number of UDI Common Shares outstanding immediately prior to the Amalgamation, after deducting the number of Directly Exchanged UDI Common Shares, all such that, in the aggregate, only one such whole Amalco Special Share shall be issued.

Each certificate formerly representing such UDI Common Shares thereafter shall entitle the holder thereof to receive an SPX Common Share certificate representing that whole number of SPX Common Shares equal to the product of the number of UDI Common Shares represented by such certificate immediately prior to the Amalgamation and the Exchange Ratio, rounded down to the nearest whole number of SPX Common Shares, provided that if more than one certificate formerly representing UDI Common Shares is registered in the name of a single holder such rounding down shall be based on the number of UDI Common Shares formerly represented by the total of such certificates. In lieu of any fractional interest in an SPX Common Share, each Person otherwise entitled to a fractional interest in an SPX Common Share shall receive a cash payment as more fully described in Section 4.4.

The Persons named below, a majority of whom are resident Canadians, shall be the first directors of Amalco: Name Residence Address ---- ----------------- ____________ ________________ ____________ ________________ ____________ ________________ (x) The by-laws of Amalco shall be the same as the by-laws of MergeCo. (k) STATED CAPITAL. For the purposes of the CBCA, the aggregate stated capital of the Amalco Common Shares issued pursuant to the Arrangement shall be B-9

61 equal to the maximum amount permitted to be added to the paid-up capital of such shares having regard to subsection 87(3) of the ITA, which amount shall not be greater than the amount permitted to be added pursuant to the CBCA; and the stated capital of the issued and outstanding Amalco Special Share issued pursuant to the Arrangement shall be equal to the Current Market Price as though the Amalco Special Share were one SPX Common Share. (l) REDEMPTION OF AMALCO SPECIAL SHARE. The one (1) outstanding Amalco Special Share shall be redeemed and cancelled, and shall be deemed to have been redeemed and cancelled for all purposes, upon the delivery by SPX Subco No. 4 to the persons holding a fractional interest in the one (1) outstanding Amalco Special Share, of an equal fractional interest in one (1) fully paid and non-assessable SPX Common Share in the aggregate. The fractional interest in such one (1) additional SPX Common Share upon such redemption shall be distributed in accordance with Article 4 to Persons who were holders of a fractional interest in the Amalco Special Share, in conjunction with the delivery of SPX Common Shares provided for in Section 2.2(j)(ii). (m) SHARE RESTRICTIONS. The following provisions shall take effect with respect to the shares of Amalco: (i) TRANSFER. The transfer of shares in the capital of Amalco is restricted in that no share may be transferred without either (i) the consent of the directors of Amalco expressed by resolution passed by the Board of Directors of Amalco or by an instrument or instruments in writing signed by all of such directors, or (ii) the consent of the holders of shares to which are attached more than 50% of the voting rights attaching to all shares for the time being outstanding entitled to vote at such time expressed by a resolution passed by such shareholders at a meeting duly called and constituted for that purpose or by an instrument or instruments in writing signed by all of such shareholders. (ii) NUMBER OF SHAREHOLDERS. The number of shareholders of Amalco, exclusive of Persons who are in its employment and exclusive of Persons who, having been formerly in the employment of Amalco, were, while in that employment, and have continued after termination of that employment to be, shareholders of Amalco, is limited to not more than 50, two or more Persons who are the joint registered owners of one or more shares being counted as one shareholder. (iii) PUBLIC DISTRIBUTIONS. Any invitation to the public to subscribe for any securities of Amalco is prohibited. B-10

62 (n) UDI OPTIONS. Subject to applicable laws and regulatory requirements, each UDI Option that is unexercised and outstanding immediately prior to the Effective Time shall be exchanged for an option ("REPLACEMENT OPTION") to purchase SPX Common Shares. Each Replacement Option shall continue to have, and be subject to, the same terms and conditions set forth in the relevant UDI Stock Option Plan and the applicable stock option agreement as they exist immediately prior to the Effective Time (and any document or agreement previously evidencing an UDI Option shall thereafter evidence such Replacement Option), except that (i) such Replacement Option shall be exercisable for that number of whole SPX Common Shares as is equal to the product obtained by multiplying the number of UDI Common Shares that were issuable upon the exercise of such UDI Option immediately prior to the Effective Time by the Exchange Ratio, rounded down to the nearest whole number of SPX Common Shares, (ii) the exercise price per share for the SPX Common Shares issuable upon exercise of such Replacement Option shall be equal to the quotient determined by dividing the exercise price per UDI Common Share at which such UDI Option is exercisable immediately prior to the Effective Time (adjusted, where necessary, for the U.S. dollar/Canadian dollar exchange rate effective as of the close of business on the Effective Date) by the Exchange Ratio, rounded up to the nearest whole cent, and (iii) such Replacement Option shall vest fully immediately following the Effective Time. SECTION 2.3 ANTI-DILUTION PROVISIONS. If, between the date of signing the Merger Agreement and the Effective Time, the outstanding SPX Common Shares shall have been changed into or exchanged for a different number of shares or kind of shares and/or other securities and/or property of SPX or another corporation or entity by reason of any reclassification, split-up, stock dividend or stock combination or any arrangement, amalgamation or similar statutory procedure (an "ADJUSTMENT EVENT"), then the Exchange Ratio shall be appropriately adjusted so that each holder of UDI Shares (other than a Dissenting Shareholder) shall be entitled to receive at the Effective Time, in lieu of the consideration in SPX Common Shares and provided for in Section 2.2 hereof, such number and kind of shares and/or other securities and/or property as such holder would have received if the record date and payment date for such Adjustment Event had been immediately after the Effective Time. The consideration payable on the redemption of the Amalco Special Share pursuant to Section 2.2(l) shall be similarly appropriately adjusted. If the record date for such Adjustment Event shall be prior to the Effective Time but the payment date therefor shall be subsequent to the Effective Time, SPX shall take such action as shall be required so that on such payment date any former holder of UDI B-11

63 Shares who shall have received or become entitled to receive SPX Common Shares pursuant to the Arrangement shall be entitled to receive such number or kind of shares and/or other securities and/or property as such holder would have received as a result of such event if the record date therefor had been immediately after the Effective Time. ARTICLE 3 RIGHTS OF DISSENT SECTION 3.1 RIGHTS OF DISSENT. Holders of UDI Common Shares may exercise rights of dissent ("DISSENT RIGHTS") with respect to such shares pursuant to and in the manner set forth in Section 190 of the CBCA (subject to the provisions hereof), the Interim Order and this Section 3.1 (the "DISSENT PROCEDURES") in connection with the Arrangement; provided that, notwithstanding the provisions of Subsection 190(5) of the CBCA, the written objection to the Arrangement Resolution referred to in Subsection 190(5) of the CBCA ("NOTICE OF Dissent") must be received by UDI prior to 5:00 p.m. (Toronto time) on the Business Day immediately preceding the date of the UDI Meeting. Holders of UDI Common Shares who seek to exercise such Dissent Rights and who: (a) are entitled to be paid fair value for their UDI Common Shares shall be deemed to have transferred such UDI Common Shares to UDI at the Effective Time and such UDI Common Shares shall be cancelled and cease to be outstanding at the Effective Time, all as provided in Section 2.2(a); or (b) for any reason prior to the Effective Time do not properly fulfill each of the Dissent Procedures required to be completed by a Dissenting Shareholder or, subsequent to giving Notice of Dissent and prior to the Effective Time, act inconsistently with such dissent, shall be deemed to have participated in the Arrangement on the same basis as a non-dissenting holder of UDI Common Shares that is not a holder of Directly Exchanged UDI Common Shares and shall be entitled to receive SPX Common Shares and a fractional interest in the Amalco Special Share which shall be redeemed for a fractional interest in one (1) SPX Common Share, all in accordance with Section 2.2; and in no case shall SPX, SPX Subco No. 1, SPX Subco No. 2, SPX Subco No. 3, SPX Subco No. 4, MergeCo, UDI, Amalco or any other Person be required to recognize such holders, or any other Person, as holders of UDI Common Shares after the Effective Time and the names of such holders of UDI Common Shares shall be deleted from the share register of UDI in respect of the UDI Common Shares as of the Effective Time. B-12

64 ARTICLE 4 CERTIFICATES, FRACTIONAL ENTITLEMENTS AND SETTLEMENT PROCEDURES SECTION 4.1 ISSUANCE OF CERTIFICATES REPRESENTING SPX COMMON SHARES. At or promptly after the Effective Time, SPX Subco No. 4 shall deposit with the Depositary, as custodian for the benefit of the holders of UDI Common Shares who shall ultimately receive SPX Common Shares from SPX Subco No. 4 pursuant to the Arrangement, certificates representing that whole number of SPX Common Shares to be delivered by SPX Subco No. 4 pursuant to Section 2.2. Upon surrender to the Depositary for cancellation of a certificate which immediately prior to the Effective Time represented one or more UDI Common Shares (other than Directly Exchanged UDI Common Shares and UDI Common Shares cancelled pursuant to Section 2.2(a)) together with a properly completed and executed Letter of Transmittal and such other documents and instruments as would have been required to effect the transfer of the shares formerly represented by such certificate under the CBCA and the by-laws of UDI and such additional documents and instruments as the Depositary may reasonably require, the holder of such surrendered certificate shall be entitled to receive in exchange therefor, and the Depositary shall deliver to such holder, a certificate representing that number of whole SPX Common Shares which such holder has the right to receive pursuant to Section 2.2 from SPX Subco No. 4 (together with any dividends or distributions with respect thereto pursuant to Section 4.2 and any cash in lieu of fractional SPX Common Shares pursuant to Section 4.4, less any amounts withheld pursuant to Section 4.5), and the certificate so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of UDI Common Shares that is not registered in the share register for UDI Common Shares, a certificate representing the proper number of SPX Common Shares may be issued to the transferee if the certificate representing such UDI Common Shares is presented to the Depositary, accompanied by all documents required to evidence and effect such transfer and payment of all transfer taxes, if any. Until surrendered as contemplated by this Section 4.1, each certificate which immediately prior to the Effective Time represented UDI Common Shares (other than Directly Exchanged UDI Common Shares and UDI Common Shares cancelled pursuant to Section 2.2(a)) shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender (i) the certificate representing SPX Common Shares as contemplated by this Section 4.1, (ii) a cash payment in lieu of fractional SPX Common Shares as contemplated by Section 4.4, and (iii) any dividends or distributions with a record date after the Effective Time theretofore paid or payable with respect to SPX Common Shares as contemplated by Section 4.2. At or promptly after the Effective Time, SPX shall deposit with the Depositary, as custodian for the benefit of holders of Directly Exchanged UDI Common Shares, certificates representing that whole number of SPX Common Shares issued by SPX to such holders pursuant to Section 2.2(e) and the provisions of this Section 4.1 shall apply mutatis mutandis to the exchange of certificates representing B-13

65 Directly Exchanged UDI Common Shares for certificates representing SPX Common Shares. SECTION 4.2 DISTRIBUTIONS WITH RESPECT TO UNSURRENDERED CERTIFICATES. No dividends or other distributions declared or made after the Effective Time with respect to SPX Common Shares, as applicable, with a record date after the Effective Time shall be paid to the holder of any unsurrendered certificate which immediately prior to the Effective Time represented outstanding UDI Common Shares, unless and until the holder of record of such certificate shall surrender such certificate in accordance with Section 4.1. Subject to applicable law, at the time of such surrender of any such certificate, there shall be paid to the holder of record of a certificate formerly representing UDI Common Shares, without interest, (i) the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such SPX Common Share, and (ii) on the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such SPX Common Share, as the case may be. SECTION 4.3 LOST CERTIFICATES. In the event any certificate which immediately prior to the Effective Time represented one or more outstanding UDI Common Shares shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such certificate to be lost, stolen or destroyed, the Depositary shall issue in exchange for such lost, stolen or destroyed certificate, one or more certificates representing one or more SPX Common Shares (and any dividends or distributions with respect thereto and any entitlements of the holder thereof to cash in lieu of fractional SPX Common Shares pursuant to Section 4.4) deliverable in accordance with the Plan of Arrangement and such holder's Letter of Transmittal. When authorizing such payment in exchange for any lost, stolen or destroyed certificate, the Person to whom such certificates representing SPX Common Shares are to be issued shall, as a condition precedent to the issuance thereof, give a bond satisfactory to SPX in such sum as SPX may direct or otherwise indemnify SPX in a manner satisfactory to SPX, against any claim that may be made against SPX, with respect to the certificate alleged to have been lost, stolen or destroyed. SECTION 4.4 NO FRACTIONAL SHARES. No certificates or scrip representing fractional SPX Common Shares shall be issued or delivered upon the surrender for exchange of certificates pursuant to Section 4.1 and no dividend, stock split or other change in the capital structure of SPX shall relate to any such fractional security and such fractional interests shall not entitle the owner thereof to exercise any rights as a security holder of UDI or SPX. In lieu of any such fractional securities, each Person otherwise entitled to a fractional interest in an SPX B-14

66 Common Share shall receive a cash payment from the Depositary equal to the product of (i) such fractional interest multiplied by (ii) the Current Market Price, rounded up to the nearest whole cent. SPX and SPX Subco No. 4 shall from time to time as necessary provide the Depositary with funds sufficient to satisfy these obligations. On the sixth anniversary of the Effective Date, the aggregate number of SPX Common Shares for which no certificates were issued as a result of the foregoing provisions of this Section 4.4 shall be deemed to have been surrendered by the Depositary for no consideration to SPX or SPX Subco No. 4 as appropriate. SECTION 4.5 WITHHOLDING RIGHTS. SPX, SPX Subco No. 4, Amalco and the Depositary shall be entitled to deduct and withhold from any dividend or consideration otherwise payable to any holder of UDI Common Shares or SPX Common Shares such amounts as SPX, SPX Subco No. 4, Amalco or the Depositary is required to deduct and withhold with respect to such payment under the ITA, the United States Internal Revenue Code of 1986, as amended, or any provision of provincial, state, local or foreign tax law, in each case, as amended. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the holder of the shares in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority. To the extent that the amount so required to be deducted or withheld from any payment to a holder exceeds the cash portion of the consideration otherwise payable to the holder, SPX, SPX Subco No. 4, Amalco and the Depositary are hereby authorized to sell or otherwise dispose of such portion of the consideration as is necessary to provide sufficient funds to SPX, SPX Subco No. 4, Amalco or the Depositary, as the case may be, to enable it to comply with such deduction or withholding requirement and SPX, SPX Subco No. 4, Amalco or the Depositary shall notify the holder thereof and remit to the holder any unapplied balance of the net proceeds of such sale. SECTION 4.6 EXTINCTION OF RIGHTS. Any certificate which immediately prior to the Effective Time represented outstanding UDI Common Shares that is not deposited with all other instruments required by Section 4.1 on or prior to the sixth anniversary of the Effective Date shall cease to represent a claim or interest of any kind or nature as a shareholder of SPX. On such date, the SPX Common Shares to which the former holder of the certificate referred to in the preceding sentence was ultimately entitled shall be deemed to have been surrendered for no consideration to SPX Subco No. 4, together with all entitlements to dividends, distributions and interest in respect thereof held for such former holder. None of SPX, SPX Subco No. 4, Amalco or the Depositary shall be liable to any Person in respect of any SPX Common Shares (or dividends, distributions and interest in respect thereof) delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. B-15

Each of SPX's subsidiaries is a corporation duly incorporated and organized and validly existing under the Laws of the jurisdiction of its incorporation and has the requisite corporate power and authority to carry on its business as now being conducted. SPX and each of its subsidiaries is duly registered to do business and is in good standing in each jurisdiction in which the character of its properties, owned or leased, or the nature of its activities make such registration necessary, except where the failure to be so registered or in good standing would not, individually or in the aggregate, have a Material Adverse Effect on SPX. The copies of SPX's certificate of incorporation and bylaws filed or incorporated by reference in SPX's Annual Report on Form 10-K for the year ended December 31, 1999 are complete and correct, have not been amended and are in full force and effect. SECTION D.2 AUTHORITY RELATIVE TO THIS AGREEMENT. SPX has the requisite corporate authority to enter into this Agreement and to carry out its obligations hereunder. The execution and delivery of this Agreement and the consummation of the Transactions have been duly authorized by SPX's Board of Directors, and no other corporate proceedings on the part of SPX are necessary to authorize this Agreement and the Transactions (except for possibly obtaining shareholder approval in respect of the SPX Resolution and the approval of the issuance of the SPX Common Shares in the Plan of Arrangement). The Board of Directors of SPX, at a meeting duly called and held at which a quorum was present throughout, has unanimously determined (a) that the Transactions are in the best interest of SPX and its shareholders and (b) to recommend to SPX's shareholders that they vote their SPX Common Shares in favor of the Transactions (the "SPX BOARD RECOMMENDATION"), and the SPX Board Recommendation has not been revoked or modified. This Agreement has been duly executed and delivered by SPX and constitutes the legal, valid and binding obligation of SPX enforceable against SPX in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other Laws relating to or affecting creditors' rights generally and to general principles of equity. D-1

70 SECTION D.3 NO VIOLATIONS. (1) Neither the execution and delivery of this Agreement by SPX, the consummation of the Transactions nor compliance by SPX with any of the provisions hereof will: (i) violate, conflict with, or result in breach of any provision of or the creation of any rights in favour of another party under, require any consent, approval or notice under, or constitute a default (or an event which, with notice or lapse of time or both, would constitute a default) or result in a right of termination or acceleration or any other change in any of the rights or obligations of any party under, or result in a creation of any lien, security interest, charge or encumbrance upon any of the properties or assets of SPX or any of its subsidiaries under, any of the terms, conditions or provisions of (x) the SPX Governing Documents or the comparable governing documents of any of its subsidiaries or (y) any note, bond, mortgage, indenture, loan agreement, deed of trust, agreement, lien or other Contract, instrument or obligation to which SPX or any of its subsidiaries is a party or to which any of them, or any of their respective properties or assets, may be subject or by which SPX or any of its subsidiaries is bound; or (ii) subject to compliance with the statutes and regulations referred to in Section D.3(2) below, violate any judgment, ruling, order, writ, injunction, determination, award, decree or Law applicable to SPX or any of its subsidiaries (except, in the case of each of clauses (i) and (ii) above, for such violations, conflicts, breaches, defaults or terminations which would not, or any consents, approvals or notices which, if not given or received, would not, individually or in the aggregate, have a Material Adverse Effect on SPX). (2) No consent, approval, order or authorization of, or declaration or filing with, any Governmental Authority is required to be obtained in connection with the execution and delivery by SPX of this Agreement or the consummation by SPX of the Transactions other than (A) consents, approvals, orders, authorizations, declarations or filings of or with any Governmental Authority that are required to be disclosed pursuant to Section E.3(2), as to which no representation or warranty is made, and (B) any other consents, approvals, orders, authorizations, declarations, or filings of or with a Governmental Authority which if not obtained would not, individually or in the aggregate, have a Material Adverse Effect on SPX. SECTION D.4 CAPITALIZATION. The authorized share capital of SPX consists of 100 million SPX Common Shares and 3,000,000 shares of preferred stock, without par value, issuable in series. As of March 8, 2001, 30,447,446 SPX Common Shares were issued and outstanding and 500,000 shares were designated as Series A Preferred Stock, of which none were outstanding, and 5,000,000 SPX Common Shares were reserved for issuance pursuant to the exercise of options granted under the SPX stock option plans and set D-2

71 forth in Section D.4 of the SPX Disclosure Letter. Except for the aforesaid SPX options, there are no options, warrants or other rights, agreements or commitments of any character whatsoever ("SPX SHARE ARRANGEMENTS") requiring the issuance, grant, sale or transfer by SPX of any shares of SPX (including the SPX Common Shares) or any securities convertible into, or exchangeable or exercisable for, or otherwise evidencing a right to acquire, any shares of SPX including the SPX Common Shares) (collectively, with shares of SPX, "SPX SECURITIES"), nor are there any outstanding stock appreciation rights, phantom equity or similar rights, agreements, arrangements or commitments based upon the book value, income or other attribute of SPX ("SPX PHANTOM RIGHTS"). Since January 19, 2001, there have been no increases to any of the amounts set forth above, other than increases in the number of outstanding SPX Common Shares by reason of issuance of SPX Common Shares upon exercise of any of the outstanding SPX options set forth above, which issuances have reduced the number of such outstanding SPX options by a corresponding amount. There are no obligations of SPX or any subsidiary to repurchase, redeem or otherwise acquire any SPX Securities.

(e) All liabilities for benefits arising out of or relating to each SPX Benefit Plan established or operated pursuant to the Laws of any jurisdiction other than the United States or Canada (i) have been determined in accordance with the terms of the applicable plan document, applicable Law and actuarial assumptions appropriate for such jurisdiction and in a manner that fairly reflects the total liabilities of the applicable SPX Benefit Plan, and (ii) have been accurately reserved against or disclosed in the audited consolidated financial statements of SPX. (f) The execution of this Agreement or performance of the Transactions will not (either alone or upon the occurrence of any additional or subsequent events) (i) constitute an event under any SPX Benefit Plan, employment, termination or severance Contract, trust or loan that will or may result in any payment (whether of severance pay or otherwise), acceleration, forgiveness of indebtedness, vesting, distribution, increase in benefits or obligation to fund benefits with respect to any current or former employee, officer or director, or (ii) result in the triggering or imposition of any restrictions or limitations on the right of SPX to amend or terminate any SPX Benefit Plan and receive the full amount of any excess assets remaining or resulting from such amendment or termination, subject to applicable Taxes.

As of the Effective Time, SPX, each of its D-10

79 subsidiaries and each ERISA Affiliate will not have completely or partially withdrawn from any Multi-Employer Plan and will not be subject to any withdrawal liability as described in Section 4201 of ERISA for withdrawals that have occurred on or prior to the Effective Date.

SECTION E.9 REPORTS.

The audited financial statements and unaudited interim financial statements (including any related notes or schedules) of UDI and its consolidated subsidiaries publicly issued by UDI, or included or incorporated by reference in the UDI Securities Reports and the UDI 2000 Financial Statements, were prepared in accordance with generally accepted accounting principles in Canada consistently applied (except (i) as otherwise indicated in such financial statements and the notes thereto or, in the case of audited statements, in the related report of UDI's independent accountants; or (ii) in the case of unaudited interim financial statements, to the extent they may not include footnotes or may be condensed or summary statements), and fairly present the consolidated financial position, results of operations and changes in financial position of UDI and its consolidated subsidiaries as of the dates thereof and for the periods indicated therein (subject, in the case of any unaudited interim financial statements, to normal year-end audit adjustments which, individually or in the aggregate, would not be material in amount or effect). E-4

86 (2) UDI will deliver to SPX as soon as they become available true and complete copies of any UDI Securities Report filed by it with Securities Authorities subsequent to the date hereof. As of their respective dates, such UDI Securities Reports (excluding any information therein provided by SPX, as to which UDI makes no representation) will not contain any misrepresentation or untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading and will comply in all material respects with all applicable requirements of Law. The financial statements of UDI and its consolidated subsidiaries (including any related notes or schedules) issued thereby or to be included or incorporated by reference in such UDI Securities Reports (excluding any information therein provided by SPX, as to which UDI makes no representation) will be prepared in accordance with generally accepted accounting principles in Canada consistently applied (except (i) as otherwise indicated in such financial statements and the notes thereto or, in the case of audited statements, in the related report of UDI's independent accountants; or (ii) in the case of unaudited interim financial statements, to the extent they may not include footnotes or may be condensed or summary statements) and will present fairly the consolidated financial position, results of operations and changes in financial position of UDI and its consolidated subsidiaries as of the dates thereof and for the periods indicated therein (subject, in the case of any unaudited interim financial statements, to normal year-end audit adjustments which, individually or in the aggregate, would not be material in amount or effect). (3) UDI is a reporting issuer not in default of any of its obligations under Canadian Securities Laws.

(a) All of the capital stock of, or other ownership interest in, each of UDI's subsidiaries is validly issued, fully paid and nonassessable and is beneficially owned, directly or indirectly, by UDI, free and clear of any and all liens, charges, security interests, adverse claims, encumbrances and demands of any nature or kind whatsoever. There are no existing UDI Share Arrangements requiring the issuance, grant, sale or transfer by any UDI subsidiary of any shares of any UDI subsidiary or any securities convertible into, or exchangeable or exercisable for, or otherwise evidencing a right to acquire, any shares of any UDI subsidiary (collectively with shares of any UDI E-5

87 subsidiary, "UDI SUBSIDIARY SECURITIES"), nor are there any outstanding stock appreciation rights, phantom equity or similar rights, agreements, arrangements or commitments based upon the book value, income or other attribute of any UDI subsidiary ("UDI SUBSIDIARY PHANTOM RIGHTS"). There are no obligations of UDI or any subsidiary to repurchase, redeem or otherwise acquire any UDI Subsidiary Securities. None of the certificates of incorporation or bylaws or other organizational documents of any of UDI's subsidiaries purport to grant rights to any Person or group other than (1) customary rights with respect to corporate governance given to all shareholders pro rata in accordance with their holdings and (2) customary rights of indemnification of directors and officers. (b) A complete listing of UDI's subsidiaries, other than inactive subsidiaries with less than $1,000,000 in assets or liabilities (including contingent liabilities) (the "UDI INACTIVE SUBSIDIARIES") is set forth in Section E.11(b) of the UDI Disclosure Letter. Except as set forth in Section E.11(b) of the UDI Disclosure Letter, neither UDI nor any of its subsidiaries directly or indirectly owns any equity or similar interest in, or any interest convertible into or exchangeable or exercisable for any equity or similar interest in, any corporation, partnership, joint venture, business association or other entity other than the UDI Inactive Subsidiaries. SECTION E.12 LITIGATION. There is no litigation, suit, claim, action, prosecution, proceeding or governmental investigation pending or, to the knowledge of UDI, threatened against or relating to UDI or any of its subsidiaries (including, for greater certainty, with respect to any environmental or employee matters) that (i) involves a claim against UDI or any of its subsidiaries that (x) could reasonably be expected to result in damages in excess of $1,000,000 or seeks damages in excess of $5,000,000, (y) seeks injunctive or other equitable relief or (z) individually or in the aggregate, would, if successful (and regardless of amount), have a Material Adverse Effect on UDI; or (ii) in any manner challenges or seeks to prevent, enjoin, alter or materially delay or limit the performance of this Agreement by UDI or any of the transactions contemplated hereby. Neither UDI (or any of its subsidiaries) nor any property or asset of UDI (or any of its subsidiaries) is subject to any Governmental Order which, individually or in the aggregate, would prevent UDI from performing its material obligations under this Agreement or has a Material Adverse Effect on UDI. SECTION E.13 ENVIRONMENTAL. (1) UDI and its subsidiaries have been and are in compliance with all applicable environmental Laws, except for non-compliance that does not, individually or in the aggregate, have a Material Adverse Effect on UDI. (2) Since December 31, 1998, neither UDI nor any of its subsidiaries has ever received any notice of or been prosecuted for material non-compliance with any E-6

88 environmental Laws, nor has UDI or any of its subsidiaries settled any allegation of non-compliance short of prosecution.

Section 9601, et seq., as amended as of the date hereof) or "contaminants" (as such term is defined in the Ontario Environmental Protection Act) or petroleum products, in each case which would reasonably be expected to form the basis of liability or other obligation of UDI or any of its subsidiaries under any applicable environmental Laws except for such liabilities or obligations which do not, individually or in the aggregate, have a Material Adverse Effect on UDI. SECTION E.14 TAX MATTERS. (1) UDI and its subsidiaries have timely filed all Tax Returns required to be filed by applicable Law with respect to each of UDI and its subsidiaries or any of their income, properties or operations, except where the failure to file does not, individually or in the aggregate, have a Material Adverse Effect on UDI. All such Tax Returns are true, accurate and complete and accurately set forth all items required to be reflected or included in such Tax Returns by applicable Tax Laws, except to the extent that any inaccuracies in filed Tax Returns do not, individually or in the aggregate, have a Material Adverse Effect on UDI. UDI and its subsidiaries have timely paid all Taxes attributable to each of UDI and its subsidiaries that were due and payable without regard to whether such Taxes have been assessed, except to the extent that failure to pay does not, individually or in the aggregate, have a Material Adverse Effect on UDI. UDI has made available to SPX complete and accurate copies of all United States and Canadian federal, state, provincial, local and foreign income tax and corporate tax returns, and any amendments thereto, filed by or on behalf of UDI or any of its subsidiaries or any member of a group of corporations including UDI or any of its subsidiaries for the taxable years ending 1997, 1998 and 1999. E-7

89 (2) There are no pending or, to the knowledge of UDI, threatened audits, examinations, investigations, deficiencies, claims or other proceedings relating to Taxes of UDI or any of its subsidiaries. UDI and its subsidiaries have made adequate provisions in accordance with Canadian generally accepted accounting principles appropriately and consistently applied to each of UDI and its subsidiaries in the consolidated financial statements included in the UDI Securities Reports referred to in Section E.9(1) and in the UDI 2000 Financial Statements for the payment of all Taxes for which UDI and its subsidiaries may be liable for the periods covered thereby that were not yet due and payable as of the dates thereof, regardless of whether the liability for such Taxes is disputed. None of UDI or any of its subsidiaries is liable for Taxes in respect of the period after the date of such consolidated financial statements other than in respect of Taxes arising in the ordinary course of business and Taxes that do not, individually or in the aggregate, have a Material Adverse Effect on UDI. (3) There are no outstanding agreements or waivers extending the statutory period of limitation applicable to any material Tax Return of UDI or any of its subsidiaries, including, without limitation, any waiver or other arrangement providing for an extension of time with respect to the filing of any such Tax Return, the payment of any Tax or the issuance of an assessment or reassessment. Neither UDI nor any of its subsidiaries has made an election under Section 341(f) of the Code. Neither UDI nor any of its subsidiaries (i) has any Tax liability under United States Treasury Regulation Section 1.1502-6 or analogous state, provincial, local, or foreign law provision for the Tax liabilities of any entity other than UDI or any of its subsidiaries, or as a transferee or successor, except to the extent any such liabilities do not, individually or in the aggregate, have a Material Adverse Effect on UDI, or (ii) is a party to a Tax sharing or Tax indemnity agreement or any other agreement of a similar nature with any entity other than UDI or any of its subsidiaries that remains in effect and under which UDI or any such subsidiary could have any material liability for Taxes. Neither UDI nor any of its subsidiaries has liability for the Taxes of another Person pursuant to Section 160 of the Income Tax Act (Canada) (the "ITA")or any analogous provincial provision. No claim has been made in writing by a taxing authority in a jurisdiction where UDI or any of its subsidiaries does not file Tax Returns that UDI or any of its subsidiaries is or may be subject to taxation by that jurisdiction where such claim, if determined adversely to UDI or such subsidiary, would, individually or in the aggregate, have a Material Adverse Effect on UDI. Neither UDI nor any subsidiary that is not a domestic corporation within the meaning of Section 7701 of the Code is or has ever been engaged in a trade or business in the United States for United States federal income tax purposes, nor does UDI or any such subsidiary own any "United States real property Interest" within the meaning of Section 897 of the Code. Neither UDI nor any of its subsidiaries is or has been a controlled foreign corporation within the meaning of Section 957 of the Code. E-8

90 (4) There has been no change in ownership of UDI or any of its subsidiaries that has caused the utilization of any losses of such entities to be limited pursuant to Subsections 111(4) or (5) of the ITA or any similar provincial provisions. UDI and each of its subsidiaries has withheld or collected all amounts required to be withheld or collected by it on account of Taxes and has remitted all such amounts to the appropriate Tax authority when required by Law to do so, except where the failure to do so would not, individually or in the aggregate, have a Material Adverse Effect on UDI. With respect to any taxable period ended prior to December 31, 1994, all United States federal and state income Tax Returns and Canadian federal and provincial income and capital Tax Returns of UDI and its subsidiaries have been audited by the relevant Taxing Authority or are closed by the applicable statue of limitations. None of UDI or any of its subsidiaries has entered into an agreement contemplated by Section 191.3 of the ITA. For all transactions between UDI or any of its subsidiaries, on the one hand, and any non-resident Person with whom UDI or such subsidiary was not dealing at arm's-length, for the purposes of the ITA, on the other hand, during a taxation year commencing after 1998 and ending before the Effective Date, UDI or such subsidiary has made or obtained records or documents that satisfy the requirements of paragraphs 247(4)(a) to (c) of the ITA. UDI and each of its subsidiaries is in full compliance with all terms and conditions of any Tax exemptions or other Tax-sparing agreement or order of a foreign government and the consummation of the Transactions shall not have any adverse effect on the continued validity and effectiveness of any such Tax exemptions or other Tax-sparing agreement or order. SECTION E.15 COMPLIANCE WITH LAWS. UDI and each of its subsidiaries each: (a) conducts its businesses in compliance with all Laws applicable thereto or to its employees or properties; (b) has all permits, licenses, authorizations, orders and approvals of, and has made all filings, applications and registrations with, all Governmental Authorities that are required in order to permit it to conduct its businesses substantially as presently conducted; all such permits, licenses, authorizations, orders and approvals are in full force and effect and, to UDI's knowledge, no suspension or cancellation of any of them is threatened; and (c) has received, since December 31, 1998, no notification or communication from any Governmental Authority (i) asserting that it is not in compliance with any Laws or Governmental Orders, (ii) threatening to revoke any permit, license, authorization, order or approval, or (iii) failing to approve any proposed E-9

91 acquisition, or stating the intention not to approve any acquisition proposed to be effected by it within a certain time period or indefinitely; except for instances which do not, individually or in the aggregate, have a Material Adverse Effect on UDI. SECTION E.16 EMPLOYEE BENEFITS. (a) True and complete copies of all UDI Benefit Plans and related documents, and all amendments thereto, have been made available to SPX. (b) UDI has administered each UDI Benefit Plan in all material respects in accordance with the terms thereof and all applicable Laws and all contributions, premiums and payments required to be made under the terms of any UDI Benefit Plan have been made. Each UDI Benefit Plan which is intended to be qualified under Section 401(a) of the Code has received a favorable determination letter from the Internal Revenue Service, and UDI is not aware of any circumstances reasonably likely to adversely affect the qualified status of such plan. UDI has made available to SPX reasonably acceptable evidence that each UDI Canadian Pension Plan and all amendments thereto have been accepted for registration by Canada Customs and Revenue Agency and any provincial Governmental Authority having jurisdiction over such UDI Canadian Pension Plan. Nothing has occurred which would result in the revocation of the registration of any UDI Canadian Pension Plan under the ITA and any applicable provincial pension legislation. All amounts paid by UDI under the provisions of the UDI Canadian Pension Plans will be deductible for income tax purposes. (c) No material liability under Title IV of ERISA has been or is reasonably expected to be incurred by UDI or any of its subsidiaries or any ERISA Affiliate. No Pension Plan of UDI or any of its subsidiaries or any ERISA Affiliate has incurred any "accumulated funding deficiency," as defined in Section 412 of the Code and Section 302 of ERISA, whether or not waived. (d) Each UDI Canadian Pension Plan that is a defined benefit pension plan is fully funded on both a "going concern" and a "solvency" basis, as determined in accordance with the actuarial assumptions and methods used in the most recent actuarial report filed with (and accepted for filing by) the applicable Governmental Authorities in respect of each such UDI Canadian Pension Plan. There has been no withdrawal by UDI of assets from any UDI Canadian Pension Plan and no application for approval of a withdrawal of assets has been made to any Governmental Authority. Any application of surplus assets in any of the UDI Canadian Pension Plans to offset required employer contributions to such UDI Canadian Pension Plans has been permitted by Law and was permitted under the terms of the relevant UDI Canadian Pension Plan and associated funding agreement. E-10

92 (e) All liabilities for benefits arising out of or relating to each UDI Benefit Plan established or operated pursuant to the Laws of any jurisdiction other than the United States or Canada (i) have been determined in accordance with the terms of the applicable plan document, applicable Law and actuarial assumptions appropriate for such jurisdiction and in a manner that fairly reflects the total liabilities of the applicable UDI Benefit Plan, and (ii) have been accurately reserved against or disclosed in the audited consolidated financial statements of UDI. (f) The execution of this Agreement or the performance of the Transactions will not (either alone or upon the occurrence of any additional or subsequent events) (i) constitute an event under any UDI Benefit Plan, employment, termination or severance Contract or other Officer Obligation, trust or loan that will or may result in any payment (whether of severance pay or otherwise), acceleration, forgiveness of indebtedness, vesting, distribution, increase in benefits or obligation to fund benefits with respect to any current or former employee, officer or director, or (ii) result in the triggering or imposition of any restrictions or limitations on the right of UDI or SPX to amend or terminate any UDI Benefit Plan and receive the full amount of any excess assets remaining or resulting from such amendment or termination, subject to applicable Taxes. The execution of this Agreement or performance of the Transactions will not (either alone or upon the occurrence of any additional or subsequent events) result in any payment or benefit being made by UDI, SPX, or any of their respective affiliates with respect to any employee of UDI that will be characterized as an "excess parachute payment," within the meaning of Section 280G(b)(1) of the Code. (g) Neither UDI, any of its subsidiaries, nor any ERISA Affiliate has any material liability with respect to any benefit plan which provides life insurance, medical, severance or other employee welfare benefits to any of its employees upon his retirement or termination of employment, except as may be required by Section 4980B of the Code or any other Law. (h) Neither UDI, any of its subsidiaries, nor any ERISA Affiliate has incurred or reasonably expects to incur any withdrawal liability (within the meaning of Section 4201 of ERISA) with respect to any Multi-Employer Plan which liability has not been fully paid as of the date hereof. As of the Effective Time, UDI, each of its subsidiaries and each ERISA Affiliate will not have completely or partially withdrawn from any Multi-Employer Plan and will not be subject to any withdrawal liability as described in Section 4201 of ERISA for withdrawals that have occurred on or prior to the Effective Date. Neither UDI, any of its subsidiaries nor any ERISA Affiliate has knowledge that any Multi-Employer Plan fails to qualify under Section 401(a) of the Code, is insolvent or is in reorganization within the meaning of Part 3 of Subtitle E of Title IV of ERISA. (i) UDI and each of its subsidiaries (i) is in compliance in all material respects with all applicable Laws respecting employment, employment practices, labor, E-11

93 terms and conditions of employment and wages and hours; and (ii) has withheld all material amounts required by Law or by agreement to be withheld from the wages, salaries and other payments to its employees.

(k) Schedule E.16(k) of the UDI Disclosure Letter lists all Officer Obligations to (a) any directors or officers of UDI or any subsidiary, and (ii) any employee of UDI or any subsidiary involving payments to such employee in excess of $100,000 per year or $200,000 in the aggregate. True and complete copies of all Contracts reflecting or relating to Officer Obligations that are required to be disclosed on Schedule E.16 (k) of the UDI Disclosure Letter have been delivered to SPX. SECTION E.17 INSURANCE. Section E.17 of the UDI Disclosure Letter is a true and complete description of all policies of fire, liability, production, completion bond, errors and omissions, workmen's compensation and other forms of insurance owned or held by UDI or any of its subsidiaries currently in effect or in effect at any time since December 31, 1999 covering the assets, business, operations, officers, directors or employees of UDI or any of its subsidiaries. All current insurance policies are in full force and effect, all premiums with respect thereto covering all periods up to and including the Effective Time have been paid or will be paid prior to the Effective Time, and no notice of cancellation or termination has been received with respect to any such policy. Such policies (i) are sufficient for compliance with all requirements of Law and of all Contracts to which UDI or any of its subsidiaries is a party, (ii) cover the respective policy periods and the risks or matters, and provide the coverage (including any deductibles or retentions), set forth in Section E.17 of the UDI Disclosure Letter and (iii) will not in any way be affected by, or terminate or lapse by reason of, the Transactions. During the last three years, neither UDI nor any of its subsidiaries has been refused any insurance with respect to its assets or operations, nor has its coverage been limited, by any insurance carrier to which it has applied for any such insurance or with which it has carried insurance. Neither UDI nor any of its subsidiaries has received any notice of increase in premiums with respect to, or cancellation or non-renewal of, any of its insurance policies, and neither UDI nor any of its subsidiaries has made any claim against an insurance policy as to which the insurer is denying coverage or defending the claim under a reservation of rights. E-12

94 SECTION E.18 INTELLECTUAL PROPERTY. With respect to each item of intellectual property or proprietary information used in the business of UDI and its subsidiaries ("UDI INTELLECTUAL PROPERTY"), UDI and its subsidiaries own or are validly licensed, or otherwise possess legally enforceable rights, to use the UDI Intellectual Property and the consummation of the transactions contemplated hereby will not alter or impair such ability in any respect, except for instances which do not, individually or in the aggregate, have a Material Adverse Effect on UDI. To UDI's knowledge, the conduct of the business of UDI and its subsidiaries and the UDI Intellectual Property do not infringe any rights of any Third Party, and, neither UDI nor any of its subsidiaries has received any written notice from any other third party pertaining to or challenging the right of UDI or any of its subsidiaries to use any of the UDI Intellectual Property. To UDI's knowledge, no third party is infringing upon any of the UDI Intellectual Property, except as do not, individually or in the aggregate, have a Material Adverse Effect on UDI. With respect to each item of UDI Intellectual Property that is an application, either UDI or the applicable subsidiary is the applicant or has the right to require the applicant to transfer ownership to UDI or such subsidiary of the application and of the registration once it issues. All rights of UDI and its subsidiaries in the UDI Intellectual Property are valid and subsisting and in full force and effect, except for instances which do not, individually or in the aggregate, have a Material Adverse Effect on UDI. The UDI Intellectual Property is all the intellectual property that is necessary for conduct of the business of UDI and its subsidiaries, as is currently conducted. SECTION E.19 TITLE TO ASSETS. UDI and its subsidiaries own or hold under valid Contracts all of the assets, tangible or intangible, necessary for the conduct of their business as currently conducted except where the failure to own or so hold such assets does not, individually or in the aggregate, have a Material Adverse Effect on UDI. SECTION E.20 OPINION OF FINANCIAL ADVISOR. The Board of Directors of UDI has received the opinion of BMO Nesbitt Burns, to the effect that, as of the date of this Agreement, the Transaction Consideration is fair to UDI's shareholders from a financial point of view, and such opinion has not been revoked or modified in any respect.
