                                                         EXHIBIT 10-X (iv)




                             NONCOMPETITION AGREEMENT

         THIS NONCOMPETITION AGREEMENT (this "Agreement") is entered into as of
this 7th day of February, 1996 by and between Bindley Western Industries, Inc.,
an Indiana corporation ("BWI"), and Thomas G. Slama, M.D., a shareholder of
Infectious Disease of Indiana, P.S.C. (the "Shareholder").

         WHEREAS, BWI, through its subsidiary, National Infusion Services,
Inc., is purchasing on the date hereof the Infusion Services Division of
Infectious Disease of Indiana, P.S.C. (the "Business") in exchange, in part,
for execution and delivery of this Agreement by the Shareholder;

         WHEREAS, in connection with such purchase and the entering of this
Agreement, the Shareholder and BWI have reviewed and considered the laws set
forth at 42 U.S.C. Sections 1320a-7b(b) and 1877, and believe that the terms
and conditions of this Agreement are in compliance with these laws.

         NOW, THEREFORE, in consideration of the mutual promises set forth
herein and for other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the parties hereto agree as
follows:

1.       COVENANT NOT TO COMPETE; NONDISCLOSURE.

                 (a)      Except on behalf of one or more of the companies in
         the BWI Group (as hereinafter defined), for a period beginning on the
         day after the date hereof and ending five years thereafter (the
         "Noncompetition Period"), the Shareholder hereby covenants and agrees
         that he shall not, directly or indirectly solicit, hire or contract
         with any healthcare-related employees of BWI or of any subsidiary,
         division or affiliate of BWI (collectively, the "BWI Group"), or any
         past healthcare-related employees of the BWI Group who were employed
         by the BWI Group within twelve (12) months prior to the date of this
         Agreement.

                 (b)      Except on behalf of one or more of the companies in
         the BWI Group, during the Noncompetition Period, the Shareholder shall
         not, directly or indirectly, reveal or disclose to third parties any
         Trade Secrets (as hereinafter defined) of the BWI Group or the
         Business, which are not, at the time in question, in the public domain
         without having become so in violation of this Agreement, except as
         authorized by BWI.  For purposes of this Agreement, the term "Trade
         Secret" includes not only that confidential or proprietorial
         information defined as a "Trade Secret" under the Indiana Trade
         Secrets Act, I.C. Section 24-2-3-1 et seq. (the "Act"), but also that
         information which possesses independent economic benefit to the BWI
         Group or the Business from not being generally known by other persons
         who can obtain economic benefit from its disclosure or use.  The
         Shareholder covenants that he will, at all times, conform his conduct
         to the requirements of the Act and will not misappropriate (e.g., use
         or disclose to any third party) any Trade Secret of the BWI Group or
         the Business.  The Shareholder recognizes that the damages
<PAGE>   2
         for a Trade Secret violation may include disgorgement of profits,
         payment of royalties, compensatory damages, punitive damages and
         attorneys' fees.

                 (c)      Except on behalf of one or more of the companies in
         the BWI Group, during the Noncompetition Period the Shareholder shall
         not, without the written consent of BWI (which consent BWI may give or
         withhold in its sole discretion),  directly or indirectly (i) own any
         interest in (except the ownership of less than five percent of the
         capital interest in a publicly traded entity or indirect ownership of
         less than five percent as a participant in an employee benefit plan)
         or manage (whether as an owner, employee, consultant or other agent of
         any type whatsoever) a business identical or substantially similar to
         the Business in the State of Indiana, or (ii) except where the failure
         to do so without first obtaining BWI's written consent would
         constitute a health risk to the potential recipient, sell, offer or
         provide to any person or entity which is a past or present supplier,
         client, patient or customer of the Business a product or service
         substantially similar to products or services offered by the Business;
         provided, however, that the foregoing is not intended to prohibit or
         restrict, and shall not be construed as prohibiting or restricting,
         the Shareholder from engaging in the practice of medicine
         substantially in the manner in which the Shareholder engaged in the
         practice of medicine immediately prior to the commencement of the
         Noncompetition Period or in any other manner that does not contravene
         the foregoing restrictive covenants.  By way of explanation and
         amplification of the foregoing, the Shareholder is a physician who, in
         the course of his medical practice, refers patients to, and manages
         the care of patients who are receiving services from, various sources
         that provide infusion services and other services identical or similar
         to those provided by the Business.  Nothing in this Noncompetition
         Agreement is intended to prohibit the Shareholder, in his capacity as
         a physician, from continuing to refer patients to and manage the care
         of patients who are receiving services from other infusion centers or
         other businesses that compete with the Business.  It is understood
         that the Shareholder may, in his capacity as a physician, be required
         to become involved as a physician and health care provider in or
         otherwise establish working relationships of various types with
         managed care plans or other health care provider groups or networks
         that are or may become providers of infusion services or other
         services similar to those provided by the Business, and that if he is
         required to be an employee (solely in the capacity as a physician) of
         any such plan or group he may become a participant in one or more
         employer-sponsored benefit plans that may own employer securities
         (which would be a circumstance that the Shareholder could not
         control).  The establishment and maintenance of such relationships in
         the course of the conduct of the medical practice of the Shareholder
         is not intended to be prohibited by the foregoing restrictive
         covenants.  Rather, such restrictive covenants are intended to
         prohibit the Shareholder from becoming financially interested as an
         owner (or the economic equivalent) in, or from becoming involved in a
         management position (as opposed to a position in which the Shareholder
         is merely rendering medical care and advice) with, a business
         identical or substantially similar to the Business in the State of
         Indiana and from soliciting past or present suppliers, clients,
         patients or customers of the Business for any competitor of the
         Business.

                 (d)      The covenants contained in this Section 1 shall be
         construed as a series of separate and severable covenants which are
         identical in terms except for geographic coverage.  The Shareholder
         and BWI agree that if in any proceeding, the tribunal shall refuse to
         enforce fully any covenants contained herein because such covenants
         cover too extensive a geographic area or too long a period of time or
         for any other reason whatsoever, any such covenant shall be deemed
         amended to the extent (but only to the extent) required by law.  Each
         party shall have the right to injunctive relief, in addition to all of
         its other rights and remedies at law or in equity, to enforce the
         provisions of this Agreement.

                 (e)      BWI acknowledges that all of the other shareholders
         (other than the Shareholder and Robert L. Baker, M.D.) of Infectious
         Disease of Indiana, P.S.C. ("IDI") (each an "Other Shareholder" and
         collectively the "Other Shareholders") are entering into agreements
         with BWI substantially identical to this Agreement (the "Other
         Shareholder Agreements") on or about the date hereof, and acknowledges
         that the Shareholder and some or all of the Other Shareholders may
         continue to be shareholders, officers and employees of IDI or may from
         time to time otherwise be associated with one another in one or more
         entities or business relationships for the purpose of conducting a
         medical practice or practices.  Notwithstanding anything herein to the
         contrary, no acts or actions committed or taken by any of the Other
         Shareholders, including any such acts or actions that may constitute a
         breach or violation by any such Other Shareholder of any of the Other
         Shareholder Agreements, shall constitute a direct or indirect breach
         or violation (including a "Continuing Violation" under Section 3) by
         the Shareholder of any of the Shareholder's covenants hereunder unless
         the Shareholder either (i) has authorized the acts or actions being
         committed or taken by such Other Shareholders, or (ii) is sharing in
         or otherwise receiving a direct economic benefit from the acts or
         actions of the Other Shareholders.

2.       CONSIDERATION.

         In consideration for the noncompetition obligations of the
Shareholder, BWI shall pay to the Shareholder on the date hereof, by certified
or bank cashiers check, the sum of $258,256.88.

3.        LIQUIDATED DAMAGES

                 (a)      This Section 3 sets forth certain non-exclusive
         remedies available to BWI (in addition to other legal and equitable
         remedies available to BWI) with respect to violations (or alleged
         violations) by the Shareholder of one or more of the Shareholder's
         covenants under Section 1 of this Agreement (each such covenant being
         referred to herein as a "Section 1 Covenant" and said covenants being
         collectively referred to herein as the "Section 1 Covenants").

                 (b)      For purposes of this Section 3:

                          (i)     "Liquidated Damages" means the damage
                 recovery that BWI may be entitled to seek for violation of a
                 Section 1 Covenant under the provisions of this Section 3.

                          (ii)    "Liquidated Damages Notice" means a written
                 notification given by BWI to the Shareholder, and signed by an
                 executive officer of BWI, asserting that the Shareholder has
                 violated and/or is violating a Section 1 Covenant, stating
                 with reasonable specificity the particular Section 1 Covenant
                 being violated and the factual basis supporting BWI's
                 assertion.

                  (c) The Shareholder and BWI acknowledge that it would be
         impracticable and difficult to ascertain the actual damages that BWI
         would suffer if the Shareholder commits a Continuing Violation
         (defined below) of any of his Section 1 Covenants.  The Shareholder
         and BWI have considered carefully the damages, general and special,
         which the Shareholder and BWI realize and recognize that BWI would
         sustain but which BWI cannot at this time calculate with absolute
         certainty in the event of such a Continuing Violation.  Based on all
         those considerations, the Shareholder and BWI have agreed that for
         purposes of this Section 3 the damages to BWI on account of a
         Continuing Violation should be fixed and liquidated by the mutual
         agreement of the parties as follows:

                <S>                                                       <C>

</TABLE>
  
                  (d)     BWI shall be entitled to recover Liquidated Damages
         from the Shareholder, in the amount determined under Section 3(c)
         above, only on account of a Continuing Violation of a Section 1
         Covenant.  For purposes of this Agreement, a "Continuing Violation"
         means that:

                          (i)     a violation of a Section 1 Covenant by the 
                 Shareholder in fact occurred; and





                                       
                                      4
<PAGE>   5

        (ii)    after receipt of a Liquidated Damages Notice, the Shareholder
                either:

                                  (A)  repeats a solicitation of
                          prospective employment or contracting with respect to
                          a person in violation of Section 1(a) after receiving
                          a Liquidated Damages Notice from BWI asserting a
                          violation of the Shareholder's covenants under
                          Section 1(a) for soliciting such person, or fails to
                          terminate an employment or contract relationship with
                          a person in violation of Section 1(a) within thirty
                          (30) days following the date on which the Shareholder
                          receives a Liquidated Damages Notice from BWI
                          asserting that such employment or contract
                          relationship with such person is a violation of the
                          Shareholder's covenants under Section 1(a); or

                                  (B)  continues the improper use of, or
                          makes any further prohibited disclosure of, a Trade
                          Secret in violation of Section 1(b) after receiving a
                          Liquidated Damages Notice from BWI asserting a
                          violation of the Shareholder's covenants under
                          Section 1(b) for using or disclosing such Trade
                          Secret; or

                                  (C)  sells, offers or provides a particular
                          product or service in violation of his covenant not
                          to do so under Section 1(c)(ii) after receiving a
                          Liquidated Damages Notice from BWI asserting a
                          violation of the Shareholder's covenants under
                          Section 1(c)(ii) for selling, offering or providing
                          that same product or service; or

                                  (D)  continues to own a prohibited ownership
                          interest in a specifically identified business
                          identical or substantially similar to the Business in
                          the State of Indiana in violation of his covenant
                          under Section 1(c)(i) for more than thirty (30) days
                          following the date on which the Shareholder receives
                          a Liquidated Damages Notice from BWI asserting that
                          such ownership in that specifically identified
                          business is a violation of the Shareholder's
                          covenants under Section 1(c)(i); provided, however,
                          that if the nature of the Shareholder's prohibited
                          ownership interest is such that it can be terminated
                          by the Shareholder but cannot be reasonably
                          terminated within the 30 day period provided above,
                          and if the Shareholder commences efforts to terminate
                          such ownership interest within such 30 day period and
                          thereafter diligently proceeds to take such actions
                          as may be reasonably required to effect such
                          termination, the 30 day "cure" period provided above
                          shall be extended for a period ending the earlier of
                          (1) 90 days after the expiration of such 30 day cure
                          period provided above, or (2) the date as of which
                          the Shareholder shall cease the diligent pursuit of
                          such actions as may be reasonably required to
                          terminate such ownership interest; or

<PAGE>   6
                                  (E)  continues to hold a prohibited
                          management position in a specifically identified
                          business identical or substantially similar to the
                          Business in the State of Indiana in violation of his
                          covenant under Section 1(c)(i) for more than twenty
                          (20) days following the date on which the Shareholder
                          receives a Liquidated Damages Notice from BWI
                          asserting that occupying such position in that
                          specifically identified business is a violation of
                          the Shareholder's covenants under Section 1(c)(i).

                 (e)      Under no circumstances shall BWI be entitled to
         recover Liquidated Damages more than once or for more than one
         violation of the Section 1 Covenants or for violations occurring in or
         for more than one period of time as reflected in Section 3(c),
         regardless of the number of violations that may have occurred or the
         number of separate periods of time in which violations occurred.  The
         amounts reflected as potentially recoverable Liquidated Damages in
         Section 3(c) are not recoverable amounts on a "per violation" or on a
         "per period" basis, but represent the maximum recovery of Liquidated
         Damages that BWI can potentially obtain from the Shareholder for all
         violations by the Shareholder of Section 1 Covenants in all relevant
         periods of time (in other words, the recovery of such amount reflected
         for a particular period of time precludes recovery of the amounts
         reflected for subsequent periods of time).

                 (f)      A recovery of Liquidated Damages by BWI hereunder
         shall automatically result in the cancellation of this Agreement
         effective immediately upon (but not until) payment in full of such
         recovery of Liquidated Damages to BWI.  Upon such cancellation all
         obligations of the parties to one another hereunder shall be void, of
         no force and effect and held for naught and any pending litigation,
         arbitration or other proceedings involving claims asserted by the
         parties hereto and arising hereunder shall be dismissed or withdrawn,
         all injunctions or other orders for legal and/or equitable relief with
         respect to claims arising hereunder shall be dissolved, dismissed or
         otherwise cancelled by mutual agreement, and all liability of the
         parties hereto arising hereunder, and all claims, causes of action and
         rights of BWI and the Shareholder arising hereunder, with respect to
         matters arising or occurring prior to such cancellation shall be fully
         and completely released and discharged.

                 (g)      BWI recognizes that the Shareholder may wish to
         obtain a determination as promptly as is reasonably practicable with
         respect to an alleged violation of a Section 1 Covenant that is
         disputed by the Shareholder.  Accordingly, BWI agrees that it will, if
         so elected by the Shareholder, submit such matter to binding
         arbitration under the rules and procedures of the American Arbitration
         Association.  The parties further agree that in any arbitration,
         litigation or other proceeding wherein a determination is being sought
         as to whether an alleged violation of a Section 1 Covenant is, in
         fact, a violation thereof, they will not, and will instruct their
         respective counsel that such counsel should not on their behalf, take
         any actions that are primarily intended to delay such determination
         other than delays that in good faith are reasonably necessary for
         preparation by counsel.

1.       MISCELLANEOUS.

                 (a)      Additional Actions and Documents.  Each of the
         parties hereto hereby agrees to take or cause to be taken such further
         actions, to execute, deliver and file or cause to be executed,
         delivered and filed such further documents, and will obtain such
         consents, as may be necessary or as may be reasonably requested in
         order to fully effectuate the purposes, terms and conditions of this
         Agreement.

                 (b)      Assignment.  The parties shall not assign their
         respective rights and obligations under this Agreement, in whole or in
         part, whether by operation of law or otherwise, without the prior
         written consent of the other party, and any such assignment contrary
         to the terms hereof shall be null and void and of no force and effect.
         Notwithstanding the foregoing, all of the rights of BWI under this
         Agreement may be assigned to any member of the BWI Group without the
         consent of the Shareholder.

                 (c)      Entire Agreement; Amendment.  This Agreement
         constitutes the entire agreement among the parties hereto with respect
         to the transactions contemplated herein, and it supersedes all prior
         oral or written agreements, commitments or understandings with respect
         to the matters provided for herein.  No amendment, modification or
         discharge of this Agreement shall be valid or binding unless set forth
         in writing and duly executed and delivered by the party against whom
         enforcement of the amendment, modification, or discharge is sought.


                 (d)      Waiver.  No delay or failure on the part of any party
         hereto in exercising any right, power or privilege under this
         Agreement or under any other documents furnished in connection with or
         pursuant to this Agreement shall impair any such right, power or
         privilege or be construed as a waiver of any default or any
         acquiescence therein.  No single or partial exercise of any such
         right, power or privilege shall preclude the further exercise of such
         right, power or privilege, or the exercise of any other right, power
         or privilege.  No waiver shall be valid against any party hereto
         unless made in writing and signed by the party against whom
         enforcement of such waiver is sought and then only to the extent
         expressly specified therein.

                 (e)      Governing Law.  This Agreement, the rights and
         obligations of the parties hereto, and any claims or disputes relating
         thereto, shall be governed by and construed in accordance with the
         laws of the State of Indiana (excluding the choice of law rules
         thereof).

                 (f)      Notices.  All notices, demands, requests, or other
         communications that may be or are required to be given, served, or
         sent by any party to any other party pursuant to this Agreement shall
         be in writing and shall be hand delivered, sent by overnight courier

         corporation, shall be deemed sufficiently given, served, sent,
         received or delivered for all purposes at such time as it is delivered

         (with respect to a telecopy or telex) the answerback being deemed
         conclusive, but not exclusive, evidence of such delivery) or at such

         this Agreement may be executed in as many counterparts as may be

         behalf of, each party, or that the signatures of all persons required
         to bind any party, appear on each counterpart; but it shall be
         sufficient that the signature of, or on behalf of, each party, or that
         the signatures of the persons required to bind any party, appear on
         one or more of the counterparts.  All counterparts shall collectively
         constitute a single agreement.  It shall not be necessary in making

         of counterparts containing the respective signatures of, or on behalf
         of, all of the parties hereto.
