        Re: Severance
          Agreement and Release of All Claims

         

        Dear
          Peter:

         

        As
          communicated to you on June 29, 2007, the Board of Directors and management
          team
          of Bioanalytical Systems, Inc. have determined to make a change that will
          result
          in the elimination of your position with the Company. You were initially
          placed
          on a two-week paid leave and given continued access to Company facilities
          and
          systems, in exchange for certain obligations on your part. That leave was
          subsequently extended to August 28, 2007, to give you sufficient time to
          consult
          with counsel. As you are aware, BASi announced your separation effective
          as of
          August 28 in its Form 8-K filed with the SEC that same date.

         

        Following
          the discussions between your counsel and counsel for BASi, BASi is prepared
          to
          offer you a severance package with the terms detailed in this letter. Because
          this severance offer is a modified version of the original offer presented
          to
          you on August 11, 2007, the period spelled out in paragraph 19 below to
          consider
          this Agreement has already expired. However, in an effort to facilitate
          the
          resolution of these discussions, BASi will give you until October 5 to
          consider
          this modified version of the Agreement and to return an executed copy to
          BASi.


         

        BASi
          has
          paid you all compensation due and owing for service prior to your separation
          date (including payment for all accrued but unused vacation), and you will
          not
          be entitled to any additional compensation from BASi or to participate
          in any of
          BASi's benefit plans (except as otherwise specifically provided herein)
          other
          than as set forth in the Agreement below. In addition, to the extent you
          have
          not already done so, you are expected to return all keys, computers, key
          cards,
          files and other Company property, of any kind, to the Company by October
          5,
          2007.

                  Admission of Liability.
                  This Agreement shall not in any way be construed as (a) an admission
                  by
                  BASi that it has acted wrongfully with respect to you or any other
                  person,

                  admission
                  by Kissinger that he acted wrongfully with respect to BASi or any
                  other
                  person, or that BASi has any rights whatsoever against
                  Kissinger.

              


         

        	3.  	
                Resignation.
                  Pursuant to this Agreement, Kissinger will be deemed to have resigned
                  his
                  employment and his position as an officer of BASi effective as
                  of August
                  28, 2007. Kissinger further agrees to resign his membership on
                  the BASi
                  Board of Directors immediately following his appointment to an
                  unpaid
                  Chairman Emeritus position. 

              


         

        	4.  	
                Claims
                  released by Kissinger.
                  By
                  signing this Agreement, Kissinger unconditionally and fully releases
                  and
                  forever discharges BASi from (a) any and all possible claims, known
                  or
                  unknown, arising out of or from his employment with BASi under
                  any and all
                  possible legal, equitable, tort, contract or statutory theories,
                  including
                  but not limited to any claims for constructive or wrongful discharge
                  or
                  breach of contract, except for any claims relating to accrued and
                  vested
                  rights under a retirement plan; (b) any and all claims arising
                  on or
                  before the date Kissinger signs this Agreement, including but not
                  limited
                  to any charges, claims, demands or actions under Title VII of the
                  Civil Rights Act of 1964 and the Equal Pay Act, 42 U.S.C.
                  § 2000e et
                  seq.,
                  Section 1981 of the Civil Rights Act of 1866, 42 U.S.C. § 1981, the
                  Age Discrimination in Employment Act, the Older Workers’ Benefit
                  Protection Act, the Americans with Disabilities Act, 42 U.S.C.
                  § 12101
                  et seq.,
                  the Indiana Civil Rights Law, the Employee Retirement Income Security
                  Act,
                  29 U.S.C. § 1001 et
                  seq.,
                  the United States Constitution, the Indiana Constitution, any and
                  all
                  amendments to said statutes, and any other federal, state or local
                  statute
                  or law, ordinance or regulation, dealing in any way with employment
                  or
                  employment-related benefits and all claims for costs and attorneys’ fees;
                  and (c) all claims Kissinger may have against BASi arising out
                  of
                  Kissinger employment and/or termination of employment with BASi.
                  Kissinger
                  agrees and understands that any claims he may have under the
                  aforementioned laws, statutes or any other federal, state or local
                  law,
                  ordinance, rule or regulation are effectively waived by this Agreement.
                  Kissinger further acknowledges and agrees that he has received
                  all
                  compensation from BASi to which he is entitled on account of his
                  service
                  prior to his separation effective August 28, 2007, including pay
                  for
                  accrued but unused vacation. BASi and Kissinger acknowledge and
                  agree,
                  however, that the release/waiver of claims set forth in this paragraph
                  4
                  does not release, affect or relinquish (i) any of Kissinger's rights
                  as a
                  shareholder of BASi, (ii) any of Kissinger's rights (or BASi's
                  obligations) under this Agreement or any other agreement between
                  BASi and
                  Kissinger executed concurrently with or subsequent to this Agreement,
                  (iii) any rights Kissinger may have with respect to any vested
                  benefits
                  under any of the Company's employee retirement and/or welfare benefit
                  plans, including without limitation under any applicable 401(k)
                  plan or
                  (iv) any rights Kissinger may have for indemnification of any third-party
                  claim relating to Kissinger's service as an employee, officer and/or
                  director of BASi. Kissinger understands that the signing of this
                  Agreement
                  prevents him from making any further claims against BASi in connection
                  with his employment and the termination of his employment with
                  BASi.
                  Kissinger agrees not to bring any lawsuits against BASi relating
                  to the
                  claims he has given up, released and waived, nor will he allow
                  any suit to
                  be brought on his behalf.

                BASi
                  Claims against Kissinger.
                  BASi represents and acknowledges that its senior management is
                  unaware of
                  any claims it may have against Kissinger as of the date of this
                  Agreement,
                  including claims arising out of his service as an employee, officer
                  and/or
                  member of the Board of Directors. 

              


         

        	6.  	
                Waiver
                  of Re-employment.
                  Kissinger waives any right or claim of reinstatement to employment
                  with
                  BASi and agrees not to seek further employment with BASi. If Kissinger
                  does seek employment with BASi, BASi is under no obligation to
                  consider
                  him for employment.

                Payments

                  In exchange for and in consideration of Kissinger's agreement to
                  release
                  claims against BASi as described in paragraph 4 and in consideration
                  of
                  the other promises contained in this Agreement, BASi agrees as
                  follows:

              


         

        	a.  	
                BASI
                  agrees to pay Kissinger a severance benefit of One Hundred Seventy-Five
                  Thousand Dollars and No Cents ($175,000.00), less tax and other
                  deductions
                  required by law. One half of this amount (Eighty-Seven Thousand
                  Five
                  Hundred Dollars and No Cents ($87,500.00), will be paid in a lump-sum
                  payment on BASi's first regular payroll date following the Release
                  Effective Date. The remaining half of this amount will be paid
                  in six (6)
                  equal monthly installments beginning in November 2007 and ending
                  in April
                  2008. Unless Kissinger notifies BASi’s payroll department of a different
                  bank account, these amounts will be deposited in the bank account
                  that
                  Kissinger has previously designated for direct
                  deposit;

        	b.  	
                Additionally,
                  BASi shall pay Kissinger an additional monthly payment equal to
                  the
                  monthly premium cost to Kissinger to continue health insurance
                  coverage
                  for Kissinger and any covered dependents under BASi’s group health
                  insurance program pursuant to the federal law known as COBRA (the
“Monthly
                  Payment”) for a period of twelve (12) consecutive months. Kissinger may
                  use the Monthly Payment to pay COBRA premiums or for any other
                  purpose.
                  The first Monthly Payment shall be paid to Kissinger on BASi’s first
                  regular payroll date following the Release Effective Date and the
                  Monthly
                  Payments shall continue thereafter for eleven (11) consecutive
                  months.
                  These payments will be deposited in the bank account that Kissinger
                  has
                  previously designated for direct deposit, unless Kissinger notifies
                  BASi's
                  payroll department of a different bank
                  account.

              


         

        	c.  	
                Kissinger
                  agrees that all of his stock options, including vested and unvested
                  stock
                  options, shall be irrevocably terminated and of no further effect
                  as of
                  the date hereof.

              


         

        	d.  	
                Kissinger,
                  if he so desires, shall promptly contact the National Life Insurance
                  Company to convert the life insurance on Kissinger's life to Kissinger.
                  BASi shall provide reasonable assistance to Kissinger to support
                  any such
                  conversion of such life insurance policy to an individual policy
                  (if such
                  right is available under the policy). BASi shall have no obligation
                  to
                  fund this policy following Kissinger's separation effective as
                  of August

                Acknowledgement.
                  Kissinger acknowledges that he is not entitled to any of the payments
                  and
                  benefits listed in paragraphs 7(a)-(b) of this Agreement unless he
                  signs this Agreement.

              


         

        	9.  	
                Non-Disparagement.
                  In consideration of the promises made in this Agreement, Kissinger
                  and
                  BASi each agree that he/it shall not make any false, negative or
                  disparaging remarks or comments to any person and/or entity about
                  the
                  other party to this Agreement, nor shall Kissinger or BASi make
                  any
                  statement that may subject the other party to potential embarrassment,
                  humiliation or any other negative consequence; provided, however,
                  nothing
                  in this paragraph 9 shall prohibit either party from making any
                  statements as may be required or compelled by law, including without
                  limitation pursuant to any judicial or administrative process.
                  The Parties
                  agree to the issuance of the press release/media statement attached
                  hereto
                  as Exhibit A, and each party shall have the right to make statements
                  consistent with such press release/media
                  statement.

                Confidentiality.
                  The parties understand that BASi will be required to file this
                  Agreement
                  with the SEC as part of its reporting obligations. Otherwise, BASi
                  and
                  Kissinger each agree to keep strictly confidential and not to disclose
                  any
                  of the terms of this Agreement to any third parties; provided,
                  however,
                  (a) any Party may disclose the terms of this Agreement as may be
                  required
                  by applicable law or by judicial or administrative process; (b)
                  any Party
                  may disclose the terms of this Agreement in any action or proceeding
                  to
                  enforce this Agreement or relating to the enforcement of this Agreement;
                  (c) BASi may disclose the terms of this Agreement to its management,
                  its
                  counsel and its accountants; and (d) Kissinger may disclose the
                  terms of
                  this Agreement to his immediate family, his counsel, his accountants
                  and
                  his financial advisors, provided that such individuals in turn
                  agree to
                  keep same confidential and not make any disclosures in any manner
                  that is
                  inconsistent with the terms of this
                  Agreement.

              


         

        	11.  	
                Consultation
                  with Attorney.
                  Kissinger agrees that he has read this Agreement and the releases
                  contained herein, that he understands all of the terms hereof,
                  that he has
                  not been coerced, threatened or intimidated into signing this Agreement,
                  and that he executes this Agreement voluntarily and with full knowledge
                  of
                  its meaning and consequences and that he has had sufficient opportunity
                  to
                  consult with his attorney regarding this Agreement. Kissinger further
                  acknowledges that BASi hereby advises him that he should consult
                  with an
                  attorney before executing this Agreement.

              


         

        	12.  	
                Severability.
                  Kissinger agrees that if he breaches any obligation set forth in
                  this
                  Agreement, BASi shall have the right to set off an amount from
                  future
                  payments described in this Agreement equal to the damages caused
                  by such
                  breach, in addition to any other remedies to which BASi may be
                  entitled
                  under law. The Parties further understand and agree that in the
                  event that
                  this Agreement is ever held to be invalid or unenforceable, in
                  whole or in
                  part, as to any particular type of claim or charge or as to any
                  particular
                  circumstances, this Agreement shall remain fully valid and enforceable
                  as
                  to all other claims, charges and
                  circumstances.

                Restrictive
                  Covenants.
                  Kissinger agrees that for the two (2) years immediately following
                  the
                  effective date hereof (which, in the event of a breach of this
                  Paragraph
                  13 by Kissinger, shall be extended automatically by a number of
                  days equal

                  of
                  securities of an issuer whose securities are listed on a national

                Modification.
                  In the event a court of competent jurisdiction determines that
                  any of the
                  foregoing restrictions are unreasonable in terms of geographic
                  scope or
                  otherwise then Kissinger and the Company agree that the court is
                  hereby
                  authorized to reduce the scope of said restriction through application
                  of
                  the blue pencil doctrine and enforce this Paragraph 13 as so reduced.
                  If
                  any sentence, word or provision of this Paragraph 13 shall be determined
                  to be unenforceable, the same shall be severed herefrom and the
                  remainder
                  shall be enforced as if the unenforceable sentence, word or provision
                  did
                  not exist. Kissinger acknowledges that all of the provisions contained
                  in
                  this Agreement, including the restrictions of the covenant not
                  to compete,
                  are reasonable and necessary to protect the legitimate interests
                  of the
                  Company.

                Return
                  of BASi’s Property.
                  Kissinger hereby represents and warrants that he has returned to
                  BASi all
                  of BASi’s property that was in his possession or control or that any such
                  property will be returned to BASi by October 5, 2007. This includes,
                  but
                  is not limited to, keys, credit cards, phone cards, cellular telephones,
                  pages, directories, computer hardware and software, books, documents,

                Cooperation
                  and Transition Assistance.
                  Kissinger agrees that for a period of sixty (60) days following
                  the date
                  hereof (the "Cooperation Period") he will be available to assist
                  BASi with
                  transitional matters relating to his former duties with BASi, without
                  additional compensation, provided that Kissinger's obligation to
                  provide
                  assistance shall consist primarily of making himself reasonably
                  available,
                  as BASi may reasonably request, to respond to questions and confer
                  with
                  BASi's officers or other designated representatives on work transition
                  matters and nothing herein shall preclude Kissinger from engaging
                  in other
                  full-time employment or business activities during the Cooperation
                  Period.
                  BASi, in turn, agrees to allow Kissinger to serve out his current
                  terms on
                  such boards (excluding the Board of Directors of BASi and all of
                  its
                  affiliates and subsidiaries) on which he currently sits, with the
                  express
                  understanding that he shall have no authority to speak or act on
                  behalf of
                  BASi in those capacities and may not represent that he has such
                  authority.

                  by the
                  Older Worker Benefit Protection Act ("OWBPA"). Kissinger acknowledges

                  he has been advised by BASi to consult with an attorney concerning

                  at this
                  time are Kissinger and Candice Kissinger; (b) that there are no
                  other
                  employees in similar job classifications to these two individuals;
                  (c)
                  that Kissinger must sign this Agreement within the time limits
                  described
                  above in order to be eligible for benefits under it; and (d) that
                  no
                  further disclosures are required under the
                  OWBPA.

        for
        BASi. On behalf of the Board, I want to thank Pete and Candice for their

      Dr.
        Kissinger commented, “Candice and I had a wonderful thirty year run at BASi and
        it is a good time for us to move on to new opportunities. Our strengths and

        several entrepreneurial activities."
