Dear Bill and Tom:

         As you are aware, Bioanalytical Systems, Inc. (the "Company") intends
to file a registration statement on Form S-1 for the purpose of registering an
aggregate of 1.8 million shares of its Common Shares for sale to the public (the
"Offering") through underwriters led by Roney & Co. L.L.C. and The Ohio Company
(the "Underwriters"). The Common Shares being registered include Common Shares
subject to an over-allotment option to be granted to the Underwriters. It is
anticipated that the registration statement will be filed with the Securities
and Exchange Commission on or about September 26, 1997, and that the Offering
will be made on or about November 25, 1997. I have enclosed a draft of the
registration statement and schedules showing the pro forma share capitalization
of the Company prior to and after giving effect to the Offering. It is
anticipated that the public offering price of the Common Shares will be between
$9 and $11 per share.

         This purpose of this letter is to confirm our agreement that:

         1. Effective immediately prior to the time of the closing of the
underwriting agreement to be entered into between the Company and the
Underwriters with respect to the Offering (the "Underwriting Agreement") and
without the necessity of any further action on your part or on the part of the
Company (other that those actions required to deliver to you the certificates
representing the Common Shares to which you will be entitled as a result of the
conversion of the Convertible Preferred Shares and the split of the Common
Shares contemplated in connection with the Offering):

         (a)      All of the Convertible Preferred Shares of the Company held by
                  each of Primus Capital Fund II Limited Partnership ("Primus")
                  and Middlewest Ventures II, L.P.


   2



                  ("Middlewest"), aggregating 104,167 and 62,500 shares,
                  respectively will be converted into Common Shares in
                  accordance with the terms set forth in Section 2.3(c) of the
                  Articles of Incorporation of the Company, as amended (the
                  "Preferred Share Terms"), and you as holders of Convertible
                  Preferred Shares shall not have any rights under the Preferred
                  Share Terms with respect to the transactions contemplated by
                  the Underwriting Agreement. Simultaneously with your execution
                  of this letter, you will deliver to the Company: (i) the
                  certificates representing the Convertible Preferred Shares,
                  (ii) written notice of conversion and (iii) a proper
                  assignment of the certificates to the Company, as contemplated
                  by Paragraph 5 of the Preferred Share Terms, to be held by the
                  Company in escrow pending the satisfaction of the conditions
                  to the conversion of the shares described herein or returned
                  to you if those conditions are not met. We hereby confirm to
                  you that, based upon the current share capitalization of the
                  Company, each outstanding Convertible Preferred Share is
                  convertible into one Common Share of the Company, based upon
                  the Preferred Share Terms.

         (b)      The Share Purchase  Agreement  between Primus,  Middlewest and
                  the Company  dated as of March 15, 1991,  shall be  terminated
                  and of no further force or effect; provided, however, that the
                  termination of the Share Purchase  Agreement  shall not affect
                  the rights of the parties  described in Exhibit E to the Share
                  Purchase  Agreement (a copy of which is attached  hereto) (the
                  "Registration Rights Agreement"), which shall continue in full
                  force  and  effect.  You  agree,  however,  that  you will not
                  exercise  your  rights  under  Section  1 of the  Registration
                  Rights  Agreement at any time prior to the  expiration  of the
                  period set forth in the lock-up agreement required pursuant to
                  the Underwriting Agreement and that you will not exercise your
                  rights under Section 2 of the  Registration  Rights  Agreement
                  with respect to the Offering.

         (c)      The  Shareholders  Agreement  between you and the  "Management
                  Shareholders" of the Company named therein,  dated as of March
                  15,  1991,  shall be  terminated  and of no  further  force or
                  effect.  The Company agrees that, for so long as either of you
                  hold  more  than 5% of the  outstanding  Common  Shares of the
                  Company,  it will use its best  efforts  to cause  one  person
                  designated by that shareholder to be nominated for election to
                  the Board of Directors of the Company upon the  expiration  of
                  the term of office of the directorships now held by you or any
                  successive term.  Consistent with the Company's past practice,
                  service on the Board would not entail  compensation beyond out
                  of pocket expenses.

         2. You will vote all of the Convertible Preferred Shares held by you in
favor of the approval of an amendment to the Articles of Incorporation of the
Company that, among other things, will (a) delete the current provisions of
Section 2.3(c) thereof, and (b) increase the number of authorized Preferred
Shares of the Company to 1,000,000 shares (the "Amended Articles of
Incorporation"). To that end, you hereby appoint Peter T. Kissinger and Ronald
E. Shoup, and either of them, with power of substitution, as your proxy and
agent with full power to attend any meeting

                                      - 2 -

of shareholders of the Company and to vote on your behalf all of the Convertible
Preferred Shares outstanding in your names in favor of the approval of the
Amended Articles of Incorporation as described herein (or to execute a consent
to shareholder action in lieu of a meeting), and this proxy shall be deemed to
be coupled with an interest and shall not be subject to revocation by you
without the consent of the Company.

         3. You agree to execute the lock-up  agreement as required  pursuant to
the Underwriting Agreement.

         In the event that the Offering is not made on or before December 31,
1997, then your agreements set forth in paragraph 1 above shall terminate at the
close of business on that date. The Company agrees that the Amended Articles of
Incorporation described in paragraph 2 above shall not be filed with the
Secretary of State of Indiana and will not become effective until immediately
prior to the effective time of the closing of the Underwriting Agreement.

         If this letter correctly sets forth the terms of our agreements, I
would appreciate it if you would sign and return the copy provided for that
purpose, and the documents described in paragraph 1(a) above (forms of which are
provided herewith). Thank you for your cooperation in this matter.


                                       Very truly yours,

                                       Bioanalytical Systems, Inc.

                                    EXHIBIT E


                          Registration of Common Shares

         1. Required Registration. At any time and from time to time, upon the
receipt by the Company from an Investor of a written request for the
registration of all or any portion of the Common Shares owned by such Investor,
the Company shall prepare and file within 60 days of receipt of such request a
registration statement under the Securities Act of 1933 (the "1933 Act")
covering the Common Shares which are subject to such request and shall use its
best efforts to cause such registration statement to become effective within 120
days of receipt of such request. The Investors shall be entitled to an unlimited
number of registrations under this Section l; provided, however, that the
Company shall not be required to bear the expense of more than one such
registration for all the Investors and the Investor making the request shall
bear the expense of any additional registrations. In the event that an Investor
determines for any reason not to proceed with a registration of Common Shares
requested pursuant to this Section l at any time before the registration
statement has been declared effective by the Securities and Exchange Commission
("SEC"), and such registration statement, if theretofore filed with the SEC, is
withdrawn with respect to the Common Shares covered thereby, and such Investor
agrees to bear its own expenses incurred in connection therewith and to
reimburse the Company for the expenses incurred by it attributable to the
registration of such Common Shares, then the Investors shall not be deemed to
have exercised their right to require the Company to register Common Shares
pursuant to this Section l at the expense of the Company. The Company shall not
effect any registration of its securities (other than on Forms S-4 or S-8, or
any successor or similar form) from the date of a request to register Common
Shares pursuant to this Section 1 until the earlier of (i) 90 days after the
date on which all securities covered by such registration statement have been
sold or (ii) 180 days after the effective date of such registration statement.

         2. Incidental Registration. Each time the Company shall determine to
proceed with the preparation and filing of a registration statement under the
1933 Act in connection with the proposed offer and sale for money of any of its
securities by the Company or any of its security holders (other than on Forms
S-4 or S-8, or any successor or similar form), the Company will give written
notice of its determination to the Investors and the other record holders of the
Common Shares. Upon the written request of an Investor or holder given to the
Company within 20 days after the mailing of any such notice by the Company as
provided in this Section 2, the Company shall, subject to Sections 5 and 9
hereof, cause all such Common Shares which such Investor or holder has requested
to be registered to be included in such registration statement. Neither the
delivery of a notice under this Section 2 nor a request by an Investor or holder
under this Section 2 shall, in any way, obligate the Company to file any
registration statement and notwithstanding the filing of a registration
statement, the Company may, at any time before the effective date thereof, elect
to terminate the entire registration process without any further obligation to
the Investors or record holders.

         3. Short Form  Registration.  In  addition to the  registration  rights
provided in Sections 1 and 2 hereof,  if the  Company  qualifies  for the use of
Form S-3 or any similar short form registration

                                      - 5 -

   6



then in force, the Company shall, at its expense, register Common Shares on
behalf of the Investors at the request of an Investor from time to time on such
form.

         4. Limitations. Notwithstanding the provisions of Sections l and 3
hereof, (i) the Company shall have the right to delay or suspend the preparation
and filing of a registration statement for up to 90 days if in the reasonable
judgment of a majority of the Board of Directors of the Company such preparation
or filing would harm or hinder in any material fashion the ability of the
Company to conduct its affairs or would have a material adverse effect on the
business, properties or financial condition of the Company, provided, that the
Company shall use its best efforts to cause any such registration statement to
become effective within 150 days of receipt of an Investor's request therefor;
and (ii) if, prior to an Investor's request for registration, the Company has
given notice under Section 2 hereof that it intends to prepare and file a
registration statement ("Section 2 Registration Statement"), then the Company
shall have the right to delay or suspend the filing of the registration
statement requested by an Investor, provided, that the Company shall use its
best efforts to cause any such registration statement requested by an Investor
to become effective within 90 days after the date on which all securities
covered by the Section 2 Registration Statement have been sold.

         5. Pro Ration. If Common Shares, including any Common Shares of the
Company to be issued and sold by it, are to be included under Sections 1, 2 or 3
above in a registration statement which pertains to one or more underwritten
public offerings and the managing underwriters advise the Company in writing
that in their opinion the number of Common Shares requested to be included
exceeds the number of Common Shares which can be sold in such offering, the
Company will include in such registration (i) first, such Common Shares as to
which demand registration rights have been exercised under Section 1 or 3, as
the case may be (the "Demand Shares"), on a pro rata basis among the holders of
Demand Shares based on the number of Common Shares with respect to which demand
is made; (ii) second, the Common Shares which the Company proposes to issue and
sell; and (iii) third, the number of Common Shares requested by the Investors
(to the extent their request was not pursuant to Section 1 or 3) to be included
which in the opinion of such underwriters can be sold (the "Secondary Shares"),
on a pro rata basis among holders of such Secondary Shares according to the
relation the number of Common Shares owned by any such holder bears to the total
number of Common Shares owned by all such holders (exclusive of Demand Shares in
each case).

         6. Registration Procedures.  If and whenever the Company is required by
the provisions of Sections 1, 2 or 3 to effect the registration of Common Shares
under the 1933 Act, the Company will:

         (a)      prepare and file with the SEC, within 60 days of receipt of an
                  Investor's request thereof or, a registration statement with
                  respect to such securities, and use its best efforts to cause
                  such registration statement to become effective within 120
                  days of receipt of such request and remain effective for such
                  period as may be reasonably necessary to effect the sale of
                  such securities, not to exceed six months;


                                      - 6 -

   7



         (b)      prepare and file with the SEC such amendments to such
                  registration statement and supplements to the prospectus
                  contained therein as may be necessary to keep such
                  registration statement effective until the earlier of (i) the
                  date on which all securities covered by such registration
                  statement have been sold and (ii) 180 days after the effective
                  date of such registration statement;

         (c)      use its best efforts to register or qualify the Common Shares
                  for sale under such other securities or blue sky laws of such
                  jurisdictions as the Investors may reasonably request and do
                  any and all other acts and things which may be reasonably
                  necessary or desirable to enable the Investors to consummate
                  the disposition of the Common Shares in such jurisdictions;
                  provided, however, that the Company shall not be required to
                  qualify to do business or to file a general consent to service
                  of process in any such jurisdictions;

         (d)      furnish to the Investors and to the underwriters of the
                  securities being registered a reasonable number of copies of
                  the registration statement, preliminary prospectus, final
                  prospectus, and such other documents as the Investors or
                  underwriters may reasonably request in order to facilitate the
                  public offering of such securities;

         (e)      notify the participating Investors, promptly after it shall
                  receive notice thereof, of the time when such registration
                  statement has become effective or a supplement to any
                  prospectus forming a part of such registration statement has
                  been filed;

         (f)      notify the  Investors  promptly  of any request by the SEC for
                  the amending or supplementing of such  registration  statement
                  or prospectus or for additional information;

         (g)      prepare and file with the SEC, promptly upon the request of
                  the Investors, any amendments or supplements to such
                  registration statement or prospectus which, in the opinion of
                  counsel for the Investors (and concurred in by counsel for the
                  Company), is required under the 1933 Act or the rules and
                  regulations thereunder in connection with the distribution of
                  the Common Shares by the Investors;

         (h)      prepare and promptly  file with the SEC,  and promptly  notify
                  the Investors of the filing of, any amendment or supplement to
                  such registration  statement or prospectus as may be necessary
                  to correct any  statements or omissions if, at the time when a
                  prospectus  relating  to such  securities  is  required  to be
                  delivered under the 1933 Act, any event shall have occurred as
                  the  result  of  which  any  such   prospectus  or  any  other
                  prospectus as then in effect would include an untrue statement
                  of a  material  fact  or  omit  to  state  any  material  fact
                  necessary to make the statement  therein,  in the light of the
                  circumstances in which they were made, not misleading;


                                      - 7 -

   8



         (i)      advise the Investors, promptly after it shall receive notice
                  or obtain knowledge thereof, of the issuance of any stop order
                  by the SEC suspending the effectiveness of such registration
                  statement or the initiation or threatening of any proceeding
                  for that purpose and promptly use its best efforts to prevent
                  the issuance of any stop order or to obtain its withdrawal if
                  such stop order should be issued;

         (j)      at least  three days prior to the filing of any  amendment  or

                  furnish  copies  thereof to the  Investors  and  refrain  from
                  filing any such amendment or supplement to which the Investors
                  shall  have  reasonably  objected  on the  grounds  that  such
                  amendment  or  supplement  does  not  comply  in all  material
                  respects  with the  requirements  of the 1933 Act or the rules
                  and regulations  thereunder,  unless in the opinion of counsel
                  for the Company the filing of such  amendment or supplement is
                  reasonably   necessary   to  protect  the  Company   from  any
                  liabilities under any applicable federal or state law and such
                  filing will not violate applicable law; and

         8.       Indemnification

         (a)      By the Company.  The Company shall indemnify and hold harmless

                  each  person,  if  any,  who  controls  such  holder  or  such
                  underwriter  within  the  meaning  of the 1933  Act,  from and
                  against any and all loss, damage,  liability or claim to which
                  such  holder or any such  underwriter  or  controlling  person
                  becomes  subject  under  the  1933  Act or  otherwise,  and to
                  reimburse them, from time to time upon request,  for any legal
                  or other  costs or  expenses  reasonably  incurred  by them in
                  connection  with  investigating  any claims or  defending  any
                  actions, insofar as such losses, damages,  liabilities,  costs
                  or  expenses  are  caused by any untrue  statement  or alleged
                  untrue  statement  of any  material  fact  contained  in  such
                  registration  statement,  any prospectus  contained therein or
                  any  amendment or supplement  thereto,  or arise out of or are
                  based upon the omission or alleged omission to state therein a
                  material  fact  required to be stated  therein or necessary to
                  make the statements  therein, in light of the circumstances in
                  which they were made, not misleading;  provided, however, that
                  the  --------  -------  Company will not be liable in any such
                  case to the extent that any such loss, damage, liability, cost
                  or  expense  arises  out of or is  based  upon  (i) an  untrue
                  statement or alleged  untrue  statement or omission or alleged
                  omission  (other  than  a  statement  or  omission  about  the
                  Company) made in conformity with information  furnished by the
                  Investors in writing  specifically  for use in the preparation
                  of a  registration  statement  or (ii) an  untrue  or  alleged
                  untrue statement or omission or alleged omission (other than a
                  statement  or  omission   about  the  Company)   made  in  any
                  preliminary  prospectus  made in conformity  with  information
                  furnished by the Investors  where the prospectus  contained in
                  the  registration  statement  in the form filed by the Company
                  with the SEC  pursuant  to Rule 424  under  the 1933 Act shall
                  have  corrected  such statement or omission and a copy of such
                  prospectus  shall,  through no fault of the Company,  not have
                  been  sent or given to the  person  bringing  the  claim at or
                  prior to the confirmation of such sale to him.

         (b)      By Holders of Common Shares. Each holder of Common Shares that
                  are included in a  registration  pursuant to these  provisions
                  will  indemnify  and hold  harmless  the  Company,  each other
                  holder,  any underwriter and each person, if any, who controls
                  the Company,  such other holder or such underwriter,  from and
                  against any and all loss, damage, liability or claim, to which
                  the  Company or such other  holder or any  controlling  person
                  and/or any  underwriter  becomes subject under the 1933 Act or
                  otherwise  and to  reimburse  them,  from  time to  time  upon
                  request,  for any legal or other costs or expenses  reasonably
                  incurred by them in connection with  investigating  any claims
                  or  defending  any actions,  insofar as such losses,  damages,
                  liabilities,  costs,  or expenses  are caused by any untrue or
                  alleged  untrue  statement of any material  fact  contained in
                  such registration statement, any prospectus contained therein,
                  or any amendment or supplement thereto, or arise out of or are
                  based upon the omission or

                                      - 9 -

   10



                  the alleged omission to state therein a material fact required
                  to be stated therein or necessary to make the statements
                  therein, in light of the circumstances in which they were
                  made, not misleading, in each case to the extent, but only to
                  the extent, that such untrue statement or alleged untrue
                  statement or omission or alleged omission was so made in
                  reliance upon and in strict conformity with written
                  information furnished by such holder specifically for use in
                  the preparation thereof.

         (c)      Notice.  Promptly  after  receipt by an  Sections  indemnified
                  party  pursuant to the  provisions  of paragraph (a) or (b) of
                  this  Section 8 of notice of the  commencement  of any  action
                  involving  the  subject  matter  of  the  foregoing  indemnity
                  provision,  such indemnified party will, if a claim thereof is
                  to be made  against  the  indemnifying  party  pursuant to the
                  provisions of said paragraph (a) or (b),  promptly  notify the
                  indemnifying party in writing of the commencement thereof; but
                  the  omission  to so notify  the  indemnifying  party will not
                  relieve  it  from  any  liability  which  it may  have  to any
                  indemnified  party  otherwise  than  hereunder.  In case  such
                  action  is  brought  against  any  indemnified  party  and  it
                  notifies the indemnifying  party of the commencement  thereof,
                  the indemnifying party shall have the right to participate in,
                  and,  to the extent that it may wish,  jointly  with any other
                  indemnifying party similarly  notified,  to assume the defense
                  thereof,  with counsel satisfactory to such indemnified party;
                  provided,  however,  if the  defendants in any action  include
                  both  the   indemnified   --------   -------   party  and  the
                  indemnifying  party and there is a conflict of interest  which
                  would  prevent  counsel for the  indemnifying  party from also
                  representing the indemnified  party, the indemnified  party or
                  parties  shall  have the right to elect  separate  counsel  to
                  participate  in the  defense of such  action on behalf of such
                  indemnified   party  or   parties.   After   notice  from  the
                  indemnifying  party to such indemnified  party of its election
                  so to assume the defense thereof,  the indemnifying party will
                  not be  liable  to  such  indemnified  party  pursuant  to the
                  provisions of said paragraph (a) or (b) for any legal or other
                  expense  subsequently  incurred by such  indemnified  party in
                  connection  with the  defense  thereof  other than  reasonable
                  costs of investigation, unless (i) the indemnified party shall
                  have employed  counsel in  accordance  with the proviso of the
                  preceding sentence, (ii) the indemnifying party shall not have
                  employed  counsel  satisfactory  to the  indemnified  party to
                  represent the indemnified party within a reasonable time after
                  the notice of the  commencement  of the  action,  or (iii) the
                  indemnifying  party has  authorized  the employment of counsel
                  for the indemnified  party at the expense of the  indemnifying
                  party.

         (d)      Contribution. If for any reason the indemnification provided
                  for paragraphs (a) and (b) is unavailable to an indemnified
                  party or insufficient to hold it harmless as contemplated by
                  such paragraphs, then the indemnifying party shall contribute
                  to the amount paid or payable by the indemnified party as a
                  result of such loss, claim, damage or liability in such
                  proportion as is appropriate to reflect not only the relative
                  benefits received by the indemnified party and the
                  indemnifying party, but also the relative fault of the
                  indemnified party and the indemnifying party, as well as any
                  other

                                     - 10 -

   11



                  relevant equitable considerations; provided, however, that, in
                  any such case, (i) no holder of Common Shares will be required
                  to contribute any amount in excess of the purchase price of
                  all such Common Shares sold by such holder pursuant to such
                  registration statement, and (ii) no holder of Common Shares
                  guilty of a fraudulent misrepresentation (within the meaning
                  of Section 11(f) of the 1933 Act) will be entitled to
                  contribution from any holder of Common Shares who was not
                  guilty of such fraudulent misrepresentation.

                           Promptly after receipt by a holder of Common Shares
                  of notice of the commencement of any action, suit or
                  proceeding in connection with a public offering of Common
                  Shares, such holder will, if a claim for contribution in
                  respect thereof is able to be made against another party,
                  notify the contributing party of the commencement thereof. The
                  omission so to notify the contributing party will not relieve
                  it from any liability which it may have to any other party
                  other than for contribution under the Act. In case any such
                  action, suit or proceeding is brought against any party, and
                  such party notifies a contributing party of the commencement
                  thereof, the contributing party will be entitled to
                  participate therein with the notifying party and any other
                  contributing party similarly notified.

         9. Limitation of Market Activity. In connection with any registration
of Common Shares pursuant to Sections 1, 2 or 3 hereof, each holder of Common
Shares who is granted registration rights under Sections 1, 2 or 3 shall, in
consideration of such grant, agree in writing prior to the date on which the
registration statement becomes effective not to offer or sell any Common Shares
for a period of up to 120 days following the date upon which such registration
statement becomes effective under the 1933 Act if the managing underwriter so
requests.

         10. Transfer of Registration Rights. The registration rights and
related obligations provided herein may be transferred with the securities to
which they relate; provided, however, that (i) the Company shall be given
written notice by the transferor thereof at the time of such transfer stating
the name and address of the transferee and identifying the securities with
regard to which such rights are being transferred, and (ii) the transferee shall
agree in writing to assume the obligations of the transferor hereunder.

         11. Investors to Provide Information. In the event the Investors
request a registration of Common Shares, the Investors shall provide all such
information and materials and shall take all such actions as may be reasonably
required in order to permit the Company to comply with all applicable
requirements of the SEC and to obtain any desired acceleration of the effective
date of such registration statement. Specifically, the Company may require the
Investors to furnish the Company with such information regarding the Investors
and the distribution of its securities as the Company may from time to time
reasonably request in writing and as shall be required by law or the SEC.

         12. Rule 144 Reporting. With a view to making available the benefits of
certain rules and regulations of the SEC which may permit the sale of the Common
Shares to the public without registration, the Company agrees to:

         (a)      Make and keep public information available, as those terms are
                  understood and defined in Rule 144 under the 1933 Act, at all
                  times from and after 90 days following the effective date of
                  the first registration under the 1933 Act filed by the Company
                  for an offering of its securities to the general public;

         (b)      Use its best efforts to file with the SEC in a timely manner
                  all reports and other documents required of the Company under
                  the 1933 Act and the Securities Exchange Act of 1934 (the
                  "1934 Act");

         (c)      So long as an Investor owns any Common Shares, furnish to the
                  Investor forthwith upon request a written statement by the
                  Company as to its compliance with the reporting requirements
                  of Rule 144 and of the 1933 Act and the 1934 Act, a copy of
                  the most recent annual or quarterly report of the Company, and
                  such other reports and documents so filed as an Investor may
                  reasonably request in availing itself of any rule or
                  regulation of the SEC allowing an Investor to sell any such
                  securities without registration.

         13. Definition of Common Shares. For the purposes of this Exhibit E,
the term "Common Shares" shall mean the Common Shares of the Company and any
Common Shares into which the Company's Convertible Preferred Shares, par value
$8.00 per share, may be converted.
