ITEM 9.  UNDERTAKINGS.

(a)      The undersigned registrant hereby undertakes:

         (i)     To file, during any period in which offers or sales are being
made, a post-effective amendment to this Registration Statement:

                 (A)      To include any prospectus required by Section
         10(a)(3) of the Securities Act of 1933, as amended (the "Securities
         Act");

                 (B)      To reflect in the prospectus any facts or events
         arising after the effective date of this Registration Statement (or
         the most recent post-effective amendment hereof) which, individually
         or in the aggregate, represent a fundamental change in the information
         set forth in this Registration Statement; and

                 (C)      To include any material information with respect to
         the plan of distribution not previously disclosed in this Registration
         Statement or any material change to such information in this
         Registration Statement;

         Provided, however, that paragraphs (a)(i)(A) and (a)(i)(B) do not
         apply if the information required to be included in a post-effective
         amendment by those paragraphs is contained in periodic reports filed
         by the Company pursuant to Section 13 or Section 15(d) of the Exchange
         Act that are incorporated by reference in this Registration Statement.

         (ii)    That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (iii)   To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

(b)      The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Company's Annual Report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference into this Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered herein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

(c)      Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Company pursuant to the foregoing provisions, or otherwise, the Company
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the Company
of expenses incurred or paid by a director, officer or controlling person of
the Company in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with the
securities being registered, the Company will, unless in the opinion of its
counsel, the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question of whether such indemnification
by it is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of such issue.

                 shall be deposited in the Trust Fund as soon as
                 administratively feasible, but in no event later than ninety
                 (90) days from the date on which such amounts would otherwise
                 have been payable to the Participant, in accordance with
                 Department of Labor Regulation 2510.3-102.

         (b)     Matching Employer Contributions--(l) In General.  For each
                 calendar quarter, each Employer shall contribute on behalf of
                 each of its Employees for

                 whom a contribution was made pursuant to paragraph (a) of
                 this Section 4.01 an amount which will be sufficient to credit
                 each such Participant's Matching Employer Contribution Account
                 with an amount equal to (i) twenty-five percent (25%) of that
                 portion of the Participant's salary reduction for such quarter
                 pursuant to Section 4.02 hereof which is invested for such
                 quarter in the Government Securities Fund or the Equity Fund
                 described in Article VII hereof, plus (ii) fifty percent (50%)
                 of that portion of the Participant's salary reduction for such
                 quarter pursuant to Section 4.02 hereof which is invested for
                 such quarter in the Company Stock Fund described in Article
                 VII hereof; provided, however, that no portion of a
                 Participant's salary reduction shall be taken into account for
                 purposes of this computation if, prior to the end of such
                 quarter, such portion is withdrawn by, or otherwise
                 distributed to, the Participant or his Beneficiary for any
                 reason other than the Participant's attainment of age seventy
                 and one-half (70-1/2).  For any Year, the Employers may
                 decline to make any portion of the contribution specified in
                 this paragraph (b) if the Employers determine that such action
                 is necessary to ensure that the discrimination tests of
                 Section 401(m) of the Code, as amended, are satisfied; or, in
                 the alternative, the Employers may direct the Trustee to
                 distribute "excess aggregate contributions" (as defined in
                 Section 401(m)(6)(B) of such Code) to the Participants by
                 or on whose behalf such contributions were made by the last
                 day of the following Year.  All Matching Employer
                 Contributions for a Year shall be in the form of cash or
                 common stock of Kaneb Services, Inc. and shall be paid to the
                 Trustee not later than the time prescribed by law for filing
                 the consolidated Federal income tax return of the Employers
                 for the taxable year within which such Year ends, including
                 any extensions which have been granted for the filing of such
                 tax return.

"7.02    Investment of Trust Fund

         The Trustee shall generally have authority for the management of
         assets held in the Trust, to the extent provided in the Trust;
         provided that (i) all assets comprising a Participant's Matching
         Employer Contribution Account shall be invested exclusively in a fund
         consisting of the common stock of Kaneb Services, Inc. (the "Company
         Stock Fund"), (ii) all assets comprising a Participant's Employer
         Contribution Account (other than assets comprising the subaccount
         described in Section 4.04 hereof) shall be invested exclusively in a
         fund consisting of obligations of the United States of America (the
         "U.S. Government Securities Fund"), and (iii) a Participant shall
         have the right, in accordance with procedures prescribed by the
         Committee, to direct the Trustee as to the investment of assets
         comprising his Salary Reduction Contribution Account and that portion,
         if any, of his Employer Contribution Account consisting of the
         subaccount described in Section 4.04 hereof.  Any such investment
         direction by a Participant shall consist solely of the right to direct
         the extent to which such assets shall be invested in the Company Stock
         Fund, the U.S. Government Securities Fund or a fund consisting of
         corporate securities (the "Equity Fund"). Upon execution of a salary
         reduction agreement described in Section 4.02 hereof, a Participant
         shall be requested to indicate the extent to which assets shall be
         invested in such Funds on forms provided by the Committee for this
         purpose, with amounts invested to be in twenty-five percent (25%)
         increments.   A Participant may elect that future allocations--to his
         Salary Reduction Contribution Account be invested to a different
         extent, in twenty-five percent (25%) increments, on the first day of
         any Plan Year.  Requests to vary the extent to which allocations are
         to be invested shall be made on such form or forms as the Committee
         shall prescribe and shall be effective only if such completed form or
         forms are received by the Committee at least thirty (30) days prior to
         the applicable election date.  Except as otherwise provided in Section
         7.03 hereof, a Participant shall have no right to vary the extent to
         which current allocations in his Salary Reduction Contribution Account
         are invested in the three Funds.  Should a Participant fail to provide
         the Trustee with the investment directives described herein, the
         assets in the Participant's Salary Reduction Contribution Account
         shall be invested in the U.S. Government Securities Fund.  A
         Participant whose Accounts are invested to any extent in the Company
         Stock Fund shall be entitled to direct the exercise of voting rights
         with respect to the shares of Company common stock allocated to said
         Accounts.  The Committee shall obtain,

         as to all such common stock, directions from such Participant as to
         how said shares are to be voted.  The Committee shall furnish such
         directions to the Trustee, who shall then vote the shares accordingly.
         If, however, within a reasonable period of time prior to any meeting
         of stockholders of the Company as may be specified by the Committee,
         no instructions shall have been received by the Committee from such
         Participant(s), the Committee shall instruct the Trustee to vote, in
         person or by proxy, such shares in the manner determined by the
         Committee in its sole discretion.  The Trustee shall vote any
         unallocated shares of Company common stock held by it pursuant to
         written directions from the Committee."

                               AMENDMENT NO. 2 TO
                            THE KANEB SERVICES, INC.
                            SAVINGS INVESTMENT PLAN

         WHEREAS, KANEB SERVICES, INC., a corporation organized and existing
under the laws of the State of Delaware (the "Company"), has heretofore adopted
THE KANEB SERVICES, INC. SAVINGS INVESTMENT PLAN (the "Plan"); and

         WHEREAS, pursuant to the provisions of the Plan permitting the Company
to amend the Plan from time to time, the Company desires to amend the Plan in
certain respects as hereinafter provided;

         NOW, THEREFORE, the Company does hereby amend the Plan in the
following particulars, effective April 1, 1991:

         1.      Section 3.01 is hereby amended by adding at the end thereof
the following:

         "For purposes of this Section 3.01, an Employee shall be considered to
         be employed on a full-time basis if the Employee regularly works in
         excess of the number of hours per period required by his Employer to
         be classified a full-time employee. The term 'active Participant'
         shall mean any Employee currently participating in the Plan who has
         not incurred a Severance from Service."

         2. Section 4.01 (b) (2) of the Plan is hereby amended to be and read
as follows:

         "(2)    Discrimination Tests. The discrimination tests of Code section
                 401(m) are satisfied in the following manner: Each Year, (i)
                 the Average Contribution Percentage for Eligible Participants
                 who are Highly Compensated Employees for the Year shall not
                 exceed the Average Contribution Percentage for Eligible
                 Participants who are Non-Highly Compensated Employees for the
                 Year multiplied by 1.25; or (ii) the Average Contribution
                 Percentage for Eligible Participants who are Highly
                 Compensated Employees for the Year shall not exceed the
                 Average Contribution Percentage for Eligible Participants
<PAGE>   6
                 who are Non-Highly Compensated Employees for the Year
                 Multiplied by two (2), provided that the Average Contribution
                 Percentage for Eligible Participants who are Highly Compensated
                 Employees does not exceed the Average Contribution Percentage
                 for Eligible Participants who are Non-Highly Compensated
                 Employees by more than two (2) percentage points. In any Plan
                 Year in which the Average Contribution Percentage for Eligible
                 Participants who are Highly Compensated Employees for the Year
                 does not satisfy the limitation set forth above, the
                 contribution rate of those Eligible Participants who are Highly
                 Compensated Employees shall be reduced (in whole or less than
                 whole percentages) in descending order by rate of contribution
                 until the Average Contribution Percentage for Eligible
                 Participants who are Highly Compensated Employees for the Year
                 meets the limitation set forth above, all in accordance with
                 regulations promulgated by the Secretary of Treasury.
                 Contributions in excess of that amount determined on the basis
                 of the reduced contribution rate hereunder shall be considered
                 'excess aggregate contributions' (as defined in Code section
                 401(m)(6)(B) and regulations promulgated thereunder).

                 For purposes of this subparagraph (2), an Eligible
                 Participant's 'Contribution Percentage' shall mean the ratio
                 (expressed as a percentage), of the sum of the Matching
                 Employer Contributions under the Plan on behalf of the
                 Eligible Participant for the Year to such Eligible
                 Participant's Compensation for the Year. The 'Contribution
                 Percentage' of an Eligible Participant who has no Matching
                 Employer Contributions allocated to his Matching Employer
                 Contribution Account for the Year shall equal zero (0).
                 'Eligible Participant' shall mean any Employee who is
                 authorized under the terms of the Plan to have Matching
                 Employer Contributions allocated to his Matching Employer
                 Contribution Account for the Year, and shall include any
                 Employee who is eligible to make Salary Reduction
                 Contributions under the terms of the Plan but elects not to
                 make such contributions for the Year, who is eligible to
                 participate under the terms of the Plan but elects not to
                 participate, or who is not eligible to have Matching Employer
                 Contributions allocated to his Matching Employer Contribution
                 Account due to the limitation on Additions set forth in
                 Section 5.03 hereof.  The 'Average Contribution Percentage'
                 is the average

                                      -2-
<PAGE>   7
                 (expressed as a percentage) of the Contribution Percentages of
                 all Eligible Participants.

                 In the event that this Plan satisfies the requirements of Code
                 section 410(b) only if aggregated with one or more other
                 plans, or if one or more other plans satisfy the requirements
                 of Code section 410(b) only if aggregated with this Plan, then
                 this subparagraph (2) shall be applied by determining the
                 Contribution Percentage of Eligible Participants as if all
                 such plans were a single plan. If a Highly Compensated
                 Employee participates in two (2) or more plans of the
                 Employers to which matching contributions are made then all
                 such contributions shall be aggregated for purposes of this
                 subparagraph (2).

                 For purposes of determining the Contribution Percentage of an
                 Eligible Participant who is a Highly Compensated Employee
                 during the Year in question, the Matching Employer
                 Contributions and Compensation of such Participant shall
                 include the Matching Employer Contributions and Compensation
                 of Family Members (as defined in Code section 414(q)(6)(B)),
                 but such Family Members shall be disregarded in determining
                 the Contribution Percentage for or other Highly Compensated
                 Employees and for Eligible Participants who are Non-Highly
                 Compensated Employees.  Any 'excess aggregate contributions'
                 (as defined in Code section 401(m)(6)(B) and regulations
                 promulgated thereunder) determined under these aggregation
                 rules shall be allocated among all Family Members in
                 proportion to the contributions of each Family Member
                 thereunder.

                 Any 'excess aggregate contribution' (as defined in Code
                 section 401(m)(6)(B) and regulations promulgated thereunder),
                 together with the income allocable thereto, shall be
                 distributed (or, if not vested, forfeited) to the Participant
                 within two and one-half (2 1/2) months of the beginning of the
                 subsequent Plan Year.

                 The income allocable to an 'excess aggregate contribution' (as
                 defined in Code section 401(m)(6)(B) and regulations
                 promulgated thereunder) shall be determined by multiplying the
                 income allocable to a Participant's Matching Employer
                 Contribution Account for the Plan Year by a fraction, the
                 numerator of which is the 'excess aggregate contributions' (as
                 defined in Code

                                      -3-
<PAGE>   8
                 section 401(m)(6)(B) and regulations promulgated thereunder)
                 for the Participant, as determined above, and the denominator
                 of which is the balance of the Participant's Matching Employer
                 Contribution Account on the last day of the Plan Year, reduced
                 by the income allocable to such account for the Plan Year and
                 increased by the loss allocable to such account for the Plan
                 Year.

                 Under regulations promulgated by the Secretary of the
                 Treasury, the Committee may, in its sole discretion, elect to
                 take contributions to a Participant's Salary Reduction
                 Contribution Account into account in computing the Average
                 Contribution Percentage. However, in such a case, the Actual
                 Deferral Percentage tests under Section 4.02(e) must still be
                 computed and met separately, and in connection therewith, no
                 aggregation with Matching Employer Contributions shall be
                 permitted. Alternatively, the Employer may, in its sole
                 discretion, elect to make qualified nonelective contributions,
                 in the manner and to the extent provided by regulations under
                 Code section 401(m) promulgated by the Secretary of Treasury,
                 that would, in combination with Matching Employer
                 Contributions under the Plan, satisfy the limitation set forth
                 above. In any event, said correction of the discrimination
                 tests described herein shall be made within twelve (12) months
                 of the end of the Year.

                 In order to prevent the multiple use of the alternative
                 limitations described in (ii) above and in Section 4.02(e)(ii)
                 hereof, the limitation on the multiple use of alternative
                 limitations described in regulations promulgated under Code
                 section 401(m) by the Secretary of Treasury is specifically
                 incorporated herein and shall apply to reduce the deferral rate
                 or contribution rate of those Eligible Participants who are
                 Highly Compensated Employees, as described above and in Section
                 4.02(e), so that there is no multiple use of said alternative
                 limitations.  Any 'excess contribution' (as defined in Code
                 section 401(k)(8)(B) and regulations promulgated thereunder)
                 resulting from a reduction in deferral rate shall be
                 distributed in accordance with Section 4.02(d), and any 'excess
                 aggregate contribution' (as defined in Code section
                 401(m)(6)(B) and regulations promulgated thereunder) resulting
                 from a reduction in contribution rate shall be distributed in 

                                      -4-
<PAGE>   9
            accordance with this Section.  In lieu of said reduction, the
            Employer may make such additional contributions as described in this
            Section and Section 4.02(d) hereof, in the manner and to the extent
            provided under regulations promulgated under Code sections 401(k)
            and 401(m) by the Secretary of Treasury, so as to comply with the
            limitation on the multiple use of alternative limitations."

         3. Section 4.02 is hereby amended by adding immediately after the end
of such first paragraph the following two new paragraphs:

         "In the event that the total reduction on behalf of any Participant for
         any of his or her taxable years exceeds $7,000 (or such greater amount
         as permitted under Treasury Department regulations to reflect
         cost-of-living adjustments), such 'excess deferrals' (as defined in
         Code section 402(g)(2) and regulations promulgated thereunder),
         together with income allocable thereto, shall be distributed to the
         Participant on whose behalf such reduction was made not later than
         April 15 following the close of the Participant's taxable year in which
         the reduction was made, in the manner and to the extent provided under
         regulations promulgated by the Secretary of Treasury; provided that
         such 'excess deferrals' shall first be reduced by any 'excess
         contributions' previously distributed for the Plan Year beginning in
         that taxable year pursuant to Section 4.02(d) hereof.

         The income allocable to an 'excess deferral' (as defined in Code
         section 402(g)(2) and regulations promulgated thereunder) shall be
         determined by multiplying the income allocable to a Participant's
         Salary Reduction Contribution Account for the Plan Year by a fraction,
         the numerator of which is the 'excess deferrals' (as defined in Code
         section 402(g)(2) and regulations promulgated thereunder) of the
         Participant, as determined above, and the denominator of which is the
         balance of the Participant's Salary Reduction Contribution Account on
         the last day of the Plan Year, reduced by the income allocable to such
         account for the Plan Year and increased by the loss allocable to such
         account for the Plan Year."

         4. Section 4.02(d) of the Plan is hereby amended to be and read as
follows:

         "(d) An Employer may amend or revoke its salary reduction agreement
              with any Participant at any time if the Employer determines that
              such revocation or amendment is necessary (i) to ensure

                                      -5-
<PAGE>   10
            that a Participant's Additions for any Year will not exceed the
            limitation of Section 5.03 hereof, (ii) to ensure that Employer
            contributions made pursuant to Section 4.01 hereof are fully
            deductible by the Employer for Federal income tax purposes, (iii) to
            ensure that a Participant's Salary Reduction Contributions do not
            exceed the limitation of Section 4.02 hereof relating to 'excess
            deferrals' (as defined in Code section 402(g)(2) and regulations
            promulgated thereunder), or (iv) to ensure that the discrimination
            tests of Code section 401(k) are met for such Year. In any case in
            which such discrimination tests are not met for a Year, the Employer
            may, in the alternative, (i) direct the Trustee to distribute
            'excess contributions' (as defined in Code section 401(k)(8)(B) and
            regulations promulgated thereunder), together with the income
            allocable thereto, but first reduced by any 'excess deferrals' (as
            defined in Code section 402(g)(2) and regulations promulgated
            thereunder) previously distributed pursuant to Section 4.02 hereof
            for the taxable year ending within the Plan Year, to the Participant
            on whose behalf such contributions were made within two and one-half
            (2-1/2) months of the beginning of the subsequent Year, or (ii) make
            such additional contributions, subject to the vesting and
            distribution requirements under Section 6.03 and 6.04 hereof, and in
            the manner and to the extent provided by regulations under Code
            section 401(k) promulgated by the Secretary of Treasury, to the
            Salary Reduction Contribution Accounts of Participants who are
            Non-Highly Compensated Employees as to cause such tests to be
            satisfied. In any event, said correction of the discrimination tests
            described herein shall be made within twelve (12) months of the end
            of the Year. In addition, an Employer may amend or revoke its salary
            reduction agreement with any Participant at any time if the Employer
            determines that such revocation or amendment is necessary to ensure
            that the discrimination tests of Code section 401(m) are met for
            such Year.

            The income allocable to an 'excess contribution' (as defined in Code
            section 401(k)(8)(B) and regulations promulgated thereunder) shall
            be determined by multiplying the income allocable to a Participant's
            Salary Reduction Contribution Account for the Plan Year by a
            fraction, the numerator of which is the 'excess contributions' (as
            defined in Code section 401(k)(8)(B) and regulations

                                      -6-
<PAGE>   11
            promulgated thereunder) of the Participant, as determined under
            Section 4.02(e), and the denominator of which is the balance of the
            Participant's Salary Reduction Contribution Account on the last day
            of the Plan Year, reduced by the income allocable to such account
            for the Plan Year and increased by the loss allocable to such
            account for the Plan Year."

         5. Section 4.02(e) of the Plan is hereby amended to be and read as
follows:

         "(e)    The discrimination tests of Code section 401(k) are
                 satisfied in the following manner: Each Year, the Actual
                 Deferral Percentage for Eligible Participants who are Highly
                 Compensated Employees for the Year shall bear a relationship
                 to the Actual Deferral Percentage for Eligible Participants
                 who are Non-Highly Compensated Employees for the Year whereby
                 (i) the Actual Deferral Percentage for the group of Eligible
                 Participants who are Highly Compensated Employees for the Year
                 is not more than the Actual Deferral Percentage for Eligible
                 Participants who are Non-Highly Compensated Employees for the
                 Year multiplied by 1.25; or (ii) the excess of the Actual
                 Deferral Percentage for the group of Eligible Participants who
                 are Highly Compensated Employees for the Year over that of all
                 Eligible Participants who are Non-Highly Compensated Employees
                 for the Year shall not be more than two (2) percentage points,
                 and the Actual Deferral Percentage for the group of Eligible
                 Participants who are Highly Compensated Employees for the Year
                 is not more than the Actual Deferral Percentage of all
                 Eligible Participants who are Non-Highly Compensated Employees
                 for the Year multiplied by two (2). In any Plan Year in which
                 the Actual Deferral Percentage for Eligible Participants who
                 are Highly Compensated Employees for the Year does not satisfy
                 the limitation set forth above, the deferral rate of those
                 Eligible Participants who are Highly Compensated Employees
                 shall be reduced (in whole or less than whole percentages) in
                 descending order by rate of deferral until the Actual Deferral
                 Percentage for Eligible Participants who are Highly
                 Compensated Employees for the Year meets the limitation set
                 forth above, all in accordance with regulations promulgated by
                 the Secretary of Treasury. Contributions in excess of that
                 amount determined on the basis of the

                                      -7-
<PAGE>   12
                 reduced deferral rate hereunder shall be considered 'excess
                 contributions' (as defined in Code section 401(k)(8)(B) and
                 regulations promulgated thereunder).

                 For purposes of this paragraph (e), the 'Actual Deferral
                 Percentage' for a specified group of Eligible Participants for
                 a Year shall be the average of the ratios (expressed as a
                 percentage and calculated separately for each Eligible
                 Participant in such group) of (i) the amount of each such
                 Eligible Participant's Salary Reduction Contributions for such
                 Year, to (ii) such Participant's Compensation for the Year.
                 The 'Actual Deferral Percentage' of an Eligible Participant
                 who has no Salary Reduction Contributions paid over to the
                 Trust on his behalf for the Year shall equal zero (0).
                 'Eligible Participant' shall mean any Employee who is
                 authorized under the terms of the Plan to have contributions
                 allocated to his Salary Reduction Contribution Account for all
                 or a portion of the Year, and shall include any Employee who
                 is eligible to make Salary Reduction Contributions under the
                 terms of the Plan but elects not to make such contributions
                 for the Year, who is eligible to participate under the terms
                 of the Plan but elects not to participate, whose right to make
                 Salary Reduction Contributions has been suspended under
                 Section 4.02(h)(1) hereof, or who is not eligible to have
                 Salary Reduction Contributions allocated to his Salary
                 Reduction Contribution Account due to the limitation on
                 Additions set forth in Section 5.03 hereof.

                 In the event that this Plan satisfies the requirements of Code
                 section 401(a)(4) or 410(b) only if aggregated with one or
                 more other plans, or if one or more other plans satisfy the
                 requirements of Code section 401(a)(4) or 410(b) only if
                 aggregated with this Plan, then this paragraph (e) shall be
                 applied by determining the Contribution Percentage of Eligible
                 Participants as if all such plans were a single plan. If a
                 Highly Compensated Employee participates in two (2) or more
                 plans of the Employers to which salary reduction contributions
                 are made then all such contributions shall be aggregated for
                 purposes of this paragraph (e)

                 For purposes of determining the Actual Deferral Percentage of
                 an Eligible Participant who is a

                                      -8-
<PAGE>   13
                 Highly Compensated Employee, the Salary Reduction
                 Contributions and Compensation of such Participant shall
                 include the Salary Reduction Contributions and Compensation of
                 Family Members (as defined in Code section 414(q)(6)(B)), but
                 such Family Members shall be disregarded in determining the
                 Actual Deferral Percentage for other Highly Compensated
                 Employees and for Eligible Participants who are Non-Highly
                 Compensated Employees.  Any 'excess contributions' (as
                 defined in Code section 401(k)(8)(B) and regulations
                 promulgated thereunder) determined under these aggregation
                 rules shall be allocated among all Family Members in
                 proportion to the contributions of each Family Member
                 thereunder.

                 The provisions of Section 4.01(b)(2) with respect to the
                 limitation on the multiple use of the alternative limitations
                 described in (ii) above and in Section 4.01(b)(2)(ii) shall
                 apply in the manner provided therein."

         6. Section 4.02(h)(1) of the Plan is hereby amended to be and read as
follows:

         "(h)    No amounts may be withdrawn by a Participant from his Salary
                 Reduction Contribution Account prior to termination of
                 employment with the Employers except to the extent of an
                 election made in accordance with the following:

                 (1)      If the Participant elects a withdrawal prior to the
                          date on which he attains age 59-1/2, such withdrawal
                          (i) may not include any accrued earnings and (ii)
                          will require the consent of the Committee. Such
                          consent shall be given only if the Participant is
                          able to demonstrate financial hardship. The Committee
                          will determine that the Participant has properly
                          demonstrated financial hardship only if the
                          Participant demonstrates that the purpose of the
                          withdrawal is to meet his immediate and heavy
                          financial needs, the amount of the withdrawal does
                          not exceed such financial needs, and the amount of
                          the withdrawal is not reasonably available from other
                          resources.  The Participant will be considered as
                          having demonstrated that the purpose of the
                          withdrawal is to meet his immediate and heavy
                          financial needs only if he

<PAGE>   14
                          represents that the distribution is on account of --

                          (A)     medical expenses (as described in Section
                                  213(d) of the Code) incurred (or required to
                                  be paid in advance to obtain medical care) by
                                  the Participant, his spouse or any of his
                                  dependents;

                          (B)     the purchase (excluding mortgage payments) of
                                  a principal residence for the Participant;

                          (C)     the payment of tuition and related
                                  educational fees for the next twelve (12)
                                  months of post-secondary education for the
                                  Participant, his spouse, children or
                                  dependents; or

                          (D)     the need to prevent eviction of the
                                  Participant from his principal residence or
                                  foreclosure on the mortgage of the
                                  Participant's principal residence.

                          Moreover, the Participant will be considered as
                          having demonstrated that the amount of the withdrawal
                          is unavailable from his other resources and in an
                          amount not in excess of that necessary to satisfy his
                          immediate and heavy financial needs only if each of
                          the following requirements is satisfied:

                          (AA)    the Participant represents that the
                                  distribution is not in excess of the amount
                                  of his immediate and heavy financial needs;
                                  and

                          (BB)    the Participant has obtained all
                                  distributions, other than hardship
                                  distributions, and all nontaxable loans
                                  currently available to him under all plans
                                  currently maintained by the Employers.

                          In the event of any withdrawal by a Participant
                          pursuant to this subparagraph (1), (i) such
                          Participant's Salary Reduction Contributions under
                          this Section 4.02 and his contributions under all
                          other employee plans maintained by the Employers
                          shall be suspended for a period of twelve (12) months
                          following such withdrawal, (ii) the Participant may

                                      -10-
<PAGE>   15
                          authorize no further contributions under this Section
                          4.02 until his taxable year following his taxable
                          year in which such withdrawal occurred, and (iii) the
                          limitations set forth in the first paragraph of this
                          Section 4.02 on the amount of Salary Reduction
                          Contributions by a Participant for any year shall be
                          reduced for the Participant's taxable year following
                          his taxable year of withdrawal to the extent of any
                          Salary Reduction Contributions made during such
                          taxable year of withdrawal. Withdrawal elections
                          under this subparagraph (1) may be made at any time
                          but not more frequently than once each calendar year.
                          All withdrawals under this subparagraph shall be made
                          in the form of a lump sum. To the extent elected by a
                          Participant, any hardship withdrawal made pursuant to
                          this subparagraph (1) to such Participant shall be
                          increased by an amount equal to the lesser of (i) all
                          federal, state and local income taxes and associated
                          penalties (including, if applicable, the additional
                          income tax described in Section 6.04(a) hereof)
                          imposed with respect to such hardship withdrawal or
                          (ii) the amount, if any, in such Participant's Salary
                          Reduction Contribution Account in excess of such

                              AMENDMENT NO. 3 TO
                           THE KANEB SERVICES, INC.
                           SAVINGS INVESTMENT PLAN

        WHEREAS, KANEB SERVICES, INC., a Delaware corporation (the "Company"),
has heretofore adopted THE KANEB SERVICES, INC. SAVINGS INVESTMENT PLAN (the
"Plan"); and

        WHEREAS, pursuant to the provisions of the Plan permitting the Company
to amend the Plan from time to time, the Company desires to amend the Plan in
certain respects as hereinafter provided:

        NOW, THEREFORE, the Company does hereby amend the Plan in the following
particulars, effective October 1, 1993, unless otherwise provided herein:

        1.      The Plan is amended by adding the following new Section 3.04 to
the end of Article III thereof:

        "3.04   Special Rules for Employees of Furmanite America, Inc.

                Notwithstanding any provision to the contrary herein
                contained, the following special rules shall apply with respect
                to any Employee of Furmanite America, Inc. who immediately
                prior to October 1, 1993 was a  participant in, or eligible to
                participate in, the Furmanite America, Inc. Employee Savings
                Plan (the "Furmanite Plan"):

                (a)     Such Employee shall be eligible to become a
                        Participant in this Plan on October 1, 1993.

                (b)     For purposes of determining such Employee's
                        "vested percentage" under Section 6.03 hereof, such 
                        Employee shall be credited with Service for those 
                        periods of employment credited to such Employee under 
                        the Furmanite Plan.

                (c)     Such Employee's Elective Account, Matching
                        Account, and Discretionary Account transferred from the
                        Furmanite Plan shall be treated as part of his Salary 
                        Reduction Contribution Account, Matching Employer 
                        Contribution Account, and Employer Contribution 
                        Account hereunder, respectively. The provisions of the
                        Plan applicable to such accounts shall apply to such 
                        corresponding account transferred from the Furmanite
                        Plan, with such

                        termination of employment but not yet allocated), plus

                (b)     An amount equal to the 'vested percentage' of his
                        Employer Contribution Account and Matching Employer
                        Contribution Account balances (including any Employer 
                        contribution to be made to such account pursuant to 
                        Section 4.01 for the Year of termination of employment
                        but not yet allocated). Such vested percentage shall 
                        be determined in accordance with the following
                        schedule:

                        Payment of benefits due under this Section shall be
                        made in accordance with Section 6.04. Notwithstanding
                        any provision to the contrary herein contained, (i) a
                        Participant shall be fully vested in his Employer
                        Contribution Account and Matching Employer Contribution
                        Account balance upon his attainment of age sixty-five
                        (65), and (ii) a Participant shall be fully vested in
                        the balance in  any subaccount of his Employer
                        Contribution Account established pursuant to Section
                        4.04 hereof. In the event that the Plan is amended to
                        change the vesting schedule set forth above, a
                        Participant with at least three (3) years of Service
                        shall have the right to elect that his vested
                        percentage be determined

                pursuant to the vesting schedule prior to amendment."

     5.  Section 6.04 of the Plan is amended by redesignating existing Section
6.04 of the Plan as subsection (a) and adding the following new subsection (b),
effective October 1, 1993, and the following new subsection (c), effective for
distributions from the Plan on or after January 1, 1993:

     "(b)  Special Rules for Former Participants in the Furmanite 
           Plan--Notwithstanding any provision to the contrary herein
           contained, a Participant who participated in the Furmanite Plan as
           of October 1, 1993 may elect to have that portion of his accounts
           representing an amount transferred from the Furmanite Plan paid in a
           lump sum or in monthly, quarterly, semi-annual, or annual
           installments over a period not to exceed the lesser of (i) ten (10)
           years, or (ii) the life expectancy of the Participant or the life
           expectancy of the Participant and his Beneficiary, in which event
           the unpaid balance shall receive an income allocation on each
           Valuation Date.

           A Participant who participated in the Furmanite Plan as of October
           1, 1993 may also request, with thirty (30) days' written notice to
           the Committee, a withdrawal of all or a portion of his Thrift
           Account attributable to Employee Thrift Contributions made prior to
           July 1, 1984 and transferred from the Furmanite Plan.  Payment of
           such amount shall be in a lump sum as soon as administratively
           feasible after the first of the month coincident with or next
           following the date of receipt of the request.

      (c)  Direct Rollovers--Notwithstanding any provision of the Plan to the
           contrary, the recipient of all or any portion of a Participant's (or
           Former Participant's) benefits, other than a Beneficiary who is not a
           surviving spouse, may elect, in the manner prescribed by the
           Committee, to have any portion of an eligible rollover distribution
           paid directly to an individual retirement account described in Code
           Section 408(a), an individual retirement annuity described in Code
           Section 408(b), an annuity plan described in Code Section 403(a), or
           a qualified trust described in Code Section 401(a), that will accept
           the eligible rollover distribution, as specified by the recipient;
           provided, however, that a recipient who is a surviving spouse may
           elect a direct rollover


                                           -5-
<PAGE>   20
                   to an individual retirement account or individual retirement
                   annuity only.  For purposes of this Section 6.04(c), an
                   "eligible rollover distribution" shall mean any distribution
                   of all or any portion of the balance to the credit of the
                   recipient, except (i) a distribution that is one of a series
                   of substantially equal periodic payments (not less
                   frequently than annually) made for the life (or life
                   expectancy) of the recipient or the joint lives (or life
                   expectancies) of the recipient and the recipient's
                   designated Beneficiary, or for a specified period of ten
                   years or more; (ii) a distribution to the extent such
                   distribution is required under Code Section 401(a)(9); or
                   (iii) the portion of any distribution that is not includible
                   in gross income."

              6.   The Plan is amended by adding the following new Section
                   6.06 to the end of Article VI thereof:

          "6.06    Loans to Participants

                   The Committee is hereby authorized to establish a
                   Participant loan program.  The following provisions shall
                   apply to any and all loans to Participants:

                   The Trustee may, if the Committee consents, loan a
                   Participant an amount from, and not in excess of the value
                   (as of the immediately preceding Valuation Date) of, his
                   accounts, with such value reduced by any withdrawals made by
                   the Participant from such accounts after such Valuation Date
                   and prior to the date of the loan.  Any such loan shall be
                   treated as an investment of the Participant's accounts for
                   whom the loan is made but shall be subject to the approval
                   of the Committee which shall thoroughly investigate each
                   application for a loan.  The Committee shall consider only
                   those factors which would be considered in a normal
                   commercial setting by an entity in the business of making
                   similar loans, including but not limited to factors such as
                   the creditworthiness and the financial need of the
                   Participant.

                   In addition to such rules and regulations as the Committee
                   may adopt, all loans shall comply with the following rules
                   and conditions:

                   (a)  An application for a loan by a Participant shall be
                        made in writing to the Committee, whose action thereon 
                        shall be final.   If the Participant is married, his 
                        spouse must specifically  consent to the application 
                        within a period which is thirty (30)  days prior to 
                        the date on which the loan is made.

<PAGE>   21
                       (b)     The period of repayment for any loan shall
                               be arrived at by agreement between the Committee
                               and the borrower, but such period in no event
                               shall exceed (5) years; provided, however, that
                               such period may exceed five (5) years where the
                               proceeds of the loan are to be used to acquire,
                               construct, reconstruct or substantially
                               rehabilitate a dwelling which is to be used
                               within a reasonable time as the principal
                               residence of the Participant or a dependent of
                               the Participant. Loans made must be amortized in
                               level payments, made not less frequently than
                               quarterly, over the term of the loan, with
                               privilege of prepayment, in whole or in part, at
                               any time and from time to time.

                       (c)     Each loan made to a Participant shall be secured
                               by (i) an assignment and pledge of not more than
                               fifty percent (50%), as determined immediately
                               after the origination of the loan, of his right,
                               title and interest in and to the vested portion
                               of his accounts, and (ii) his promissory note for
                               the amount of the loan, including interest,
                               payable to the order of the Trustee. The loan
                               shall be repaid by payroll deduction or pursuant
                               to such other method as may be selected by the
                               Committee. Upon the failure of a Participant to
                               repay any loan, the Trustee shall (i) make
                               written demand for payment and shall advise the
                               Participant that payment (or, if permissible,
                               renegotiation of the loan) must be made within
                               twenty-five (25) days or default on the note will
                               occur, and (ii) furnish a copy of such written
                               demand to the Committee. The Trustee shall
                               maintain a written record of the date on which
                               written demand for repayment of a loan (or
                               payment of any installment under a loan) is
                               forwarded to a Participant and such record shall
                               be conclusive for all purposes. A "default" shall
                               occur upon the failure by a Participant to make
                               payment under (or, to the extent permitted by
                               Code Section 72(p), renegotiate) the loan by the
                               date which is twenty-five (25) days subsequent to
                               the date on which written demand for repayment of
                               such loan (or payment of such installment) is
                               forwarded to the Participant by the Trustee. Upon
                               default, the entire remaining principal balance
                               of the loan shall be treated as a deemed
                               distribution to the Participant from the Plan,
                               and the amount of such deemed distribution shall
                               be reported to the Internal Revenue Service on
                               the applicable tax form.

                   (d)  Each loan shall bear a reasonable rate of interest to
                        be fixed by the Committee and, in determining the
                        interest rate, the Committee shall take into
                        consideration interest rates currently being charged by
                        commercial lenders for loans made under similar
                        circumstances in effect on the date on which the loan
                        is made. The Committee shall not discriminate among
                        Participants in the matter of interest rates; but
                        loans granted at different times may bear different
                        interest rates if the Committee determines that the
                        difference in rates is justified and necessary to
                        reflect current economic conditions.

                   (e)  No amount shall be loaned to a Participant which would
                        cause his outstanding loan balance under the Plan to
                        exceed the lesser of (i) or (ii), where-

                              (i)  is $50,000, as reduced by the excess of the
                                   highest outstanding balance of loans to such
                                   Participant over the twelve (12)-month
                                   period ending on the day before the loan is
                                   made over the outstanding balance of loans
                                   to such Participant on the date the loan is
                                   made, and

                              (ii) is one-half (1/2) of the vested portion of
                                   his accounts as of the immediately preceding
                                   Valuation Date.

                        The amount of any loan made hereunder shall not be less
                        than $1,000. A Participant shall have no more than one
                        (1) outstanding loan at any time.

                   (f)  No distribution shall be made to any Participant or
                        Former Participant or to a Beneficiary of any such
                        Participant unless and until all unpaid loans of such
                        Participant, including accrued interest thereon, have
                        been liquidated. Foreclosure against a Participant's
                        accounts shall occur immediately upon default and shall
                        result in the reduction of such accounts to the extent
                        of unpaid principal and accrued interest; provided that
                        there shall be no foreclosure against a Participant's
                        accounts until the occurrence hereunder of an event
                        permitting distribution of such account balance. Any
                        outstanding loan balance shall continue to accrue
                        interest until paid in full or otherwise liquidated.

                   (g)  Loans shall be made available to Former Participants
                        who are parties-in-interest only as required by ERISA
                        and Department of Labor guidelines.

                   (h)  Loans shall be subject to such fees and charges, as
                        may be determined by the Committee to be reasonable,
                        representing the cost to the Plan of administering the
                        loan. Such fees and charges shall be communicated to
                        the Participant prior to the date of the loan. 

                   (i)  Any loan made prior to October 18, 1989 under the
                        Furmanite Plan shall continue to be governed by the
                        provisions of the Furmanite Plan as in effect prior to
                        such date and applicable to such loan."

              7.   Section 7.02 of the Plan is amended to be and read as
         follows:

             "7.02 Investment of Trust Fund             

                   The Trustee shall generally have authority for the
                   management of assets held in the Trust, to the extent
                   provided in the Trust; provided that (i) except as otherwise
                   provided in Section 7.03 hereof, all assets comprising a
                   Participant's Matching Employer Contribution Account shall
                   be invested exclusively in a fund consisting of the common
                   stock of Kaneb Services, Inc. (the "Company Stock Fund") and
                   (ii) a Participant shall have the right, in accordance with
                   procedures prescribed by the Committee, to direct the
                   Trustee as to the investment of assets comprising his Salary
                   Reduction Contribution Account and Employer Contribution
                   Account. Any such investment direction by a Participant shall
                   consist solely of the right to direct the extent to which
                   such assets shall be invested in such investment media as
                   may be selected from time to time by the Committee and
                   communicated to the Participant. Upon execution of a salary
                   reduction agreement described in Section 4.02 hereof, a
                   Participant shall be requested to indicate the extent to
                   which assets shall be invested in such media on forms
                   provided by the Committee for this purpose, with amounts
                   invested to be in twenty-five percent (25%) increments. A
                   Participant may elect that future allocations to his Salary
                   Reduction Contribution Account and Employer Contribution
                   Account be invested to a different extent, in twenty-five
                   percent (25%) increments, on the first day of any calendar
                   quarter. Requests to vary the extent to which allocations
                   are to be invested shall be made on such form or forms as
                   the Committee shall prescribe and shall be effective only if
                   such completed form or forms are received by the Committee
                   at least thirty (30) days prior to the applicable election
                   date. A Participant's right to vary the extent to

                        Should a Participant fail to provide the Trustee with
                        the investment directives described herein, the assets
                        in the Participant's Salary Reduction Contribution
                        Account and Employer Contribution Account shall be
                        invested as determined by the Trustee in accordance
                        with the provisions of the Trust."

                 8.     Section 7.03 of the Plan is amended to be and read as
follows:


                 "7.03  Transfer of Past Investments

                        A Participant may elect, effective as of the first day
                        of any calendar quarter, to transfer the full value of
                        his accounts invested as of the immediately preceding
                        Valuation Date in any one or more of the investment
                        media authorized pursuant to Section 7.02 hereto to any
                        one or more of the other investment media authorized
                        pursuant to such Section; provided that the transfer to
                        the other media shall be allocated to such other media
                        in twenty-five percent (25%) increments totaling
                        one-hundred percent (100%); provided, further, that
                        assets comprising a Participant's Matching Employer
                        Contribution Account will not, except as provided
                        below, be eligible for transfer to other media under

                        extent that such transferred amounts have been invested
                        in the Company Stock Fund for a period of at least two
                        (2) years.  Requests to transfer past investments shall

                             AMENDMENT NO. 4 TO
                          THE KANEB SERVICES, INC.
                           SAVINGS INVESTMENT PLAN

         WHEREAS, KANEB SERVICES, INC., a Delaware corporation (the "Company"),
has heretofore adopted THE KANEB SERVICES, INC. SAVINGS INVESTMENT PLAN (the
"Plan"); and

         WHEREAS, pursuant to the provisions of the Plan permitting the Company
to amend the Plan from time to time, the Company desires to amend the Plan in
certain respects as hereinafter provided;

         NOW, THEREFORE, the Company does hereby amend the Plan in the
following particulars, effective January 1, 1994, unless otherwise provided
herein:

         1.      Section 2.01(h) of the Plan is amended to be and read as
follows:

         "(h)    The total of all amounts paid to a Participant by the Employer
                 for personal services as reported on the Participant's Federal
                 Income Tax Withholding Statement (Form W-2) plus, to the
                 extent determined by the Committee from time to time in a
                 uniform and nondiscriminatory manner, any salary reduction
                 amounts described in Section 4.02 hereof and any amounts not
                 included in the Participant's gross income pursuant to Section
                 125 of the Code; provided, however, that for all purposes
                 other than nondiscrimination testing under Sections 401(a)(4),
                 401(k), 401(m), and 410(b) of the Code, Compensation shall
                 include only (i) base pay, (ii) overtime pay, (iii) sales
                 commissions, and (iv) shift differential pay.  For Plan Years
                 beginning after 1988 and before 1994, any compensation in
                 excess of $200,000 (as automatically increased in accordance
                 with Treasury Department regulations to reflect cost-of-living
                 adjustments) and, for Plan Years beginning after 1993, any
                 compensation in excess of $150,000 (as automatically increased
                 in accordance with Treasury Department regulations to reflect
                 cost-of-living adjustments), in any Plan Year shall not be
                 considered Compensation under this Plan.  In applying the
                 $200,000 or $150,000 limitation described above, in the case
                 of a Highly
<PAGE>   27
                 Compensated Employee who is subject to the aggregation rules
                 of Section 414(q)(6) of the Code because such Participant is
                 either a 5% owner of the Employer or one of the 10 highest
                 paid Highly Compensated Employees, such Highly Compensated
                 Employee and his Family Members shall be treated as a single
                 Participant; provided, however, that "Family Members" shall
                 mean only the Participant's spouse and any lineal descendants
                 who have not attained age 19 before the close of the year. If,
                 as a result of the application of these rules, the limitation
                 is exceeded, then the limitation shall be prorated among the
                 Participant and Family Members in proportion to the
                 Compensation of each prior to the application of the
                 limitation."

         2.      The introductory paragraph of Section 3.01 of the Plan is 
amended to be and read as follows:

         "Except for any Employee (i) who is a member of a collective
         bargaining unit, the recognized representative of which has not agreed
         to Participation in the Plan by its members, (ii) who is a leased
         employee within the meaning of Section 414 (n) (2) of the Code, or

                 and (2), where--

                 (1)      is the greater of $30,000 (or such greater amount as
                          permitted under Internal Revenue Service rulings to

                          fourth (1/4) of the dollar limitation in effect under
                          Section 415(b)(1)(A) of the Code; and

                 which contributed, or on behalf of a Participant to a
                 simplified employee pension plan to the extent such
                 contributions are deductible under Section 219 (b) (7) of the
                 Code, and any distributions from a plan of deferred

                 the Participant when distributed; (ii) amounts realized from
                 the exercise of a non-qualified stock option, or when

                 freely transferable or is no longer subject to a substantial
                 risk of forfeiture; (iii) amounts realized from the sale,
                 exchange or other disposition of stock acquired under   a
                 qualified stock option; (iv) other amounts which receive
                 special tax benefits, or contributions made by the Employer
                 (whether or not under a salary reduction agreement) towards
                 the purchase of an annuity contract described in Section
                 403(b) of the Code (whether or not the contributions are
                 excludible from the gross income of the Participant); and (v)
                 for Plan Years beginning after 1988 and before 1994,
                 compensation in excess of $200,000 (as automatically increased
                 in accordance with Treasury Department regulations to reflect
                 cost-of-living adjustments) and, for Plan Years beginning
                 after 1993, compensation in excess of $150,000 (as
                 automatically increased in accordance with Treasury Department
                 regulations to reflect cost-of-living adjustments)."

         4.      Section 5.04(b) of the Plan is amended to be and read as
follows:

         "(b)    Minimum Allocations--Notwithstanding the provisions of Section
                 5.0 2 (c) and (d), for any Year during which the Plan is
                 deemed a Top-Heavy Plan, the amount of Employer contribution
                 for the Year to be allocated to the Employer Contribution
                 Account of each Participant who is not a Key Employee and who
                 is employed by the Employers on the last day of the Year shall
                 not be less than the lesser of (i) three percent (3%) of the
                 Participant's total
<PAGE>   29
                 compensation for the Year or (ii) the highest percentage
                 obtained by dividing the amount allocated to the Employer
                 Contribution Account of any Key Employee for the Year by so
                 much of the total compensation of such Key Employee for the
                 Year as does not exceed $200,000 (as automatically adjusted in
                 accordance with Treasury Department regulations providing for
                 cost of living adjustments) for Plan Years beginning before
                 1994 and $150,000 (as automatically adjusted in accordance
                 with Treasury Department regulations providing for cost of
                 living adjustments) for Plan Years beginning after 1993;
                 provided that the requirements of this paragraph (b) shall not
                 apply to the extent that the minimum allocations set forth
                 herein are made under another defined contribution plan
                 maintained by the Employer."

         5.      Effective for distributions from the Plan made on or after
January 1, 1993, Section 6.04 (c) of the Plan is amended to be and read as 
follows:

         "(c)    Direct Rollovers--Notwithstanding any provision of the Plan to
                 the contrary that would otherwise limit a distributee's
                 election under this Section, a distributee may elect, at the
                 time and in the manner prescribed by the Committee, to have
                 any portion of an eligible rollover distribution paid directly
                 to an eligible retirement plan specified by the distributee in
                 a direct rollover. For purposes of this Section 6.04(c), the
                 following terms shall have the following meaning.

                 (1)      'Eligible rollover distribution' means any
                          distribution of all or any portion of the balance to
                          the credit of the distributee, except (i) a
                          distribution that is one of a series of substantially
                          equal periodic payments (not less frequently than
                          annually) made for the life (or life expectancy) of
                          the distributee or the joint lives (or joint life
                          expectancies) of the distributee and the
                          distributee's designated Beneficiary, or for a
                          specified period of ten years or more; (ii) a
                          distribution to the extent such distribution is
                          required under Section 401(a)(9) of the Code; and
                          (iii) the portion of any distribution that is not
                          includible in gross income.
<PAGE>   30
                 (2)      'Eligible retirement plan' means an individual
                          retirement account described in Section 408(a) of the
                          Code, an individual retirement annuity described in
                          Section 408(b) of the Code, an annuity plan described
                          in Section 403(a) of the Code, or a qualified trust
                          described in Section 401(a) of the Code, that will
                          accept the distributee's eligible rollover
                          distribution; provided, however, that in the case of
                          an eligible rollover distribution to the surviving
                          spouse, an eligible retirement plan includes only an
                          individual retirement account or individual
                          retirement annuity.

                 (3)      'Distributee' means the Participant and, with respect
                          to the interest of such spouse or former spouse, the
                          Participant's surviving spouse and the Participant's
                          spouse or former spouse who is the alternate payee
                          under a qualified domestic relations order, as
                          defined in Section 414(p) of the Code.

                 (4)      'Direct rollover' is a payment by the Plan to the
                          eligible retirement plan specified by the
                          distributee."

                                  ADDENDUM TO
                              KANEB SERVICES, INC.
                       SAVINGS INVESTMENT TRUST AGREEMENT



This ADDENDUM is entered into this 22nd day of March 1996, by and between KANEB
SERVICES, INC., a corporation (the "Company"), and THE CHARLES SCHWAB TRUST
COMPANY (the "Trustee") effective for the 1st day of April, 1996.


ARTICLE 1
INVESTMENTS

         1.1     (a) Except as provided below, the Committee shall have all
power over and responsibility for the management, disposition, and investment
of the Trust assets, and the Trustee shall comply with proper written
directions of the Committee concerning those assets.  The Committee shall not
issue directions in violation of the terms of the Plan and Trust or prohibited
by the fiduciary responsibility rules of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA").  Except to the extent required by
ERISA or otherwise provided in this Addendum, the Trustee shall have no duty or
responsibility to review, initiate action, or make recommendations regarding
Trust assets and shall retain assets until directed in writing by the Committee
to dispose of them.

                 (b)      As permitted under the Plan, each Participant and/or
beneficiary may have investment power over the account maintained for him or
her, and may direct the investment and reinvestment of assets of the account
among the options authorized by the Committee.  To the extent provided under
ERISA section 404(c), the Trustee shall not be liable for any loss, or by
reason of any breach, which results from such Participant's or beneficiary's
exercise of control.  If a Participant who has investment authority under the
terms of the plan fails to provide such directions, the Committee shall direct
the investment of the Participant's accounts.  The Committee shall maintain
records showing the interest of each Participant and/or beneficiary in the
Trust Fund.  The Trustee shall have no duty or responsibility to review or make
recommendations regarding investments made at the direction of the Committee or
Participant and shall be required to act only upon receipt of proper written
directions.

         1.2     The Trustee shall not be responsible for proper
diversification of the assets of the Trust Fund.  The Committee or the person
to whom such responsibility has been properly delegated under the requirements
of ERISA shall be responsible for the funding policy, for diversification of
assets held in trust for the Plan, and for compliance of the Trust Fund with
statutory limitations on the amount of investment in securities or other
property of the Company or its affiliated companies.

         1.3     In its administration of the Trust Fund, the Trustee shall
deliver to the Committee, or the person or persons identified by the Committee,
proxies and powers of attorney and related informational material, for any
shares or other property (other than Company Stock) held in the Trust.  The
Committee shall have responsibility for voting such shares, by proxy or in
person, except to the extent such responsibility is delegated to another
person, under the terms of the
<PAGE>   2
Plan or Trust Agreement, in which case such persons shall have such
responsibility.  The Trustee may use agents to effect such delivery to the
Committee or the person or persons identified by the Committee.  In no event
shall the Trustee be responsible for the voting of shares of securities held in
the Trust (other than Company Stock) or for ascertaining or monitoring whether,
or how, proxies are voted or whether the proper number of proxies is received.

         1.4     (a) Voting rights with respect to shares of Company Stock held
in the Trust Fund shall be voted by the Trustee in such manner as may be
determined by the respective Participant, with respect to all matters requiring
shareholder approval.  With respect to shares of Company Stock in the Trust
Fund which are allocated to Participants who fail to give directions to the
Trustee, such shares shall be voted by the Trustee based on the voting
directions of those Participants who issued directions with respect to Company
Stock allocated to their Accounts.  The number of non-voted shares to be voted
in a particular manner shall be determined by multiplying the total number of
such shares by a fraction, the numerator of which is the number of allocated
shares directed to be voted in such manner, and the denominator of which is the
total number of allocated shares directed to be voted in any manner with
respect to the matter at issue.  Participants for whom no proxies are received
will be disregarded for this purpose.  The Plan Committee may establish such
rules and guidelines as it deems necessary to properly effect the provision of
this section.

                 (b)      Notwithstanding any other provision in the Plan and
Trust to the contrary, the Trustee shall, with respect to all Company Stock
held in the Trust Fund, accept or reject the terms of any tender offer and,
accordingly, tender Company Stock held by the Trustee in the Trust Fund in
accordance with the terms and provisions of any tender offer, or not tender
such Company Stock, as directed by the respective Participants.  With respect
to shares of Company Stock which are allocated to Participants who have not
given directions, the tender or exchange rights of such shares of Company Stock
shall be exercised based on the tender or exercise directions of those
Participants who issued directions with respect to the Company Stock allocated
to their Accounts.  The Trustee shall determine these tender or exercise
directions in the same manner as voting directions are determined as provided
under the above section.  The Plan Committee may establish such rules and
guidelines as it deems appropriate to properly effect the provisions of this
section.


ARTICLE 2
USE OF AFFILIATES

         2.1     Trustee is authorized to contract or make other arrangements
with The Charles Schwab Corporation, Charles Schwab & Co., Inc., their

shall be subject to fees and commissions established by the Broker, which may
be paid from the Trust Fund or netted from the proceeds of trades.

         Trades shall not be executed through Charles Schwab & Co., Inc. unless

commissions which may be paid to The Charles Schwab Corporation, Charles Schwab
& Co., Inc., Trustee and any affiliate or subsidiary of any of them as a result
of using Charles Schwab & Co., Inc. to execute trades or for other services.

         Trustee is authorized to disclose such information as is necessary to
the operation and administration of the Trust Fund to The Charles Schwab
Corporation or any of its affiliates, and to such other persons or
organizations that Trustee determines have a legitimate business purpose for
obtaining such information.

         2.3     At the direction of the Company, Trustee may purchase shares
of regulated investment companies (or other investment vehicles) advised by The
Charles Schwab Corporation, Charles Schwab & Co., Inc. or Trustee, or any
affiliate or subsidiary of any of them ("Schwab Funds"), except to the extent
that such investment is prohibited by law or regulation.  Schwab Fund shares
may not be purchased for or held by the Trust Fund unless the Committee has
received disclosure concerning the relationship of The Charles Schwab
Corporation, Charles Schwab & Co., Inc., Trustee, and any affiliate or
subsidiary of any of them, to the Schwab Funds, and any fees which may be paid
to such entities.


ARTICLE 3
RESIGNATION OR REMOVAL OF TRUSTEE

         3.1     If either party has given notice of Trustee removal or
resignation as provided under the Trust Agreement, and upon the expiration of
the advance notice period no other successor Trustee has been appointed and has
accepted such appointment, this provision shall serve as (i) notice of
appointment of the Chairman of the Plan Committee as Trustee and (ii) as
acceptance by that person of that appointment.


ARTICLE 4

         4.1     The Trust will be administered in the State of California, and
its validity, construction, and all rights hereunder shall be governed by ERISA
and, to the extent not preempted, by the laws of California.  If any provisions
of this Agreement shall be invalid or unenforceable, the remaining provisions
shall continue to be fully effective.

         4.2     Any dispute under the Plan or Trust involving the Company and
Trustee shall be resolved by submission of the issue to a member of the
American Arbitration Association who is chosen by the Company and the Trustee.
If the Company and the Trustee cannot agree on such a choice, each shall
nominate a member of the American Arbitration Association, and the two




                                      3

paid as decided upon by the arbitrator.

         4.3     Trustee and Charles Schwab & Co., Inc. are authorized to tape
record conversations between Trustee or Charles Schwab & Co., Inc. and persons
acting on behalf of the Plan or a Participant in order to verify data on
transactions.

         4.4     This Addendum is incorporated into and is a part of the Plan 
and Trust.  Anything in any other part of the Plan or Trust that is inconsistent
with this Addendum is overridden, and in the case of such conflict, the terms

Gentlemen:

We have acted as counsel for Kaneb Services, Inc., a Delaware corporation (the
"Company"), in connection with the registration under the Securities Act of
1933 of 1,500,000 shares of the Company's common stock, no par value (the
"Shares"), to be awarded by the Company under its Savings Investment Plan (the
"Plan") upon the terms and subject to the conditions set forth in the Company's
Registration Statement on Form S-8 covering the Shares (the "Registration
Statement") to be filed with the Securities and Exchange Commission.

In connection therewith, we have examined the Registration Statement, originals
or copies certified or otherwise identified to our satisfaction of the Restated
Certificate of Incorporation of the Company, as amended, the By-laws of the
Company and such other documents and instruments as we have deemed necessary or
appropriate for the expression of the opinions contained herein.

We have assumed the authenticity and completeness of all records, certificates
and other instruments submitted to us as originals, the conformity to original
documents of all records, certificates and other instruments submitted to us as
copies, the authenticity and completeness of the originals of those records,
certificates and other instruments submitted to us as copies and the
correctness of all statements of fact contained in all records, certificates
and other instruments that we have examined.

Based on the foregoing, and having regard for such legal considerations as we
have deemed relevant, we are of the opinion that the Shares have been duly and
validly authorized for issuance and, upon issuance thereof in accordance with
the Plan, will be duly and validly issued, fully paid and nonassessable.

The opinions expressed herein relate solely to, are based solely upon and are
limited exclusively to the laws of the State of Delaware and the federal laws
of the United States of America, to the extent applicable.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name under the caption "Item 5.
Interest of Named Experts and Counsel" in the Registration Statement.

                               Very truly yours,



                               Fulbright & Jaworski L.L.P.
