          This Amendment No. 2 to the statement on Schedule 13D filed on
behalf of Appaloosa Management L.P. (the "Manager") and David A. Tepper
("Mr. Tepper" and, together with the Manager, collectively, the "Reporting
Persons") on November 1, 1999, as amended by Amendment No. 1 filed on
January 5, 2000 (collectively, the "Schedule 13D"), relates to shares of
the common stock, no par value (the "Common Stock"), of Bio-Plexus, Inc., a
Connecticut corporation (the "Company"). Capitalized terms used but not
otherwise defined herein shall have the meaning ascribed to such terms in
the Schedule 13D. The Schedule 13D is hereby amended and supplemented as
follows:

ITEM 4.   PURPOSE OF TRANSACTION.
          ----------------------

          On April 3, 2000, the Reporting Persons and the Company entered
into a first amendment to the New Note (the "First Amendment") and a second
amendment to the Bridge Note (the "Second Amendment"), which in each case
provides, among other things, for an extension of the Rollover Closing from
February 28, 2000 to April 30, 2000. On April 3, 2000, Appaloosa also made
an additional loan of $2,200,000 to the Company in the form of a 15%
Secured Note (the "Third Note"). In addition, pursuant to a letter
agreement dated April 3, 2000 (the "Second Letter Agreement"), under
certain circumstances as more fully described in Item 6, the existing $3
Warrants issued to Appaloosa, Palomino and Tersk on October 21, 1999 will
be cancelled and the Company will issue to each of them new warrants
identical in amount and substantially identical in form to the $3 Warrants
(such warrants, the "Replacement Warrants"). The First Amendment, the
Second Amendment, the Third Note and the Second Letter Agreement are
attached hereto as Exhibits 1 through 4 respectively and are incorporated
in and made a part of this Schedule 13D in their entirety by this
reference.

ITEM 6.   CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS
          WITH RESPECT TO SECURITIES OF THE ISSUER.
          --------------------------------------------------------

          The responses set forth in Items 4 and 5 of this Schedule 13D are
incorporated herein by this reference in their entirety.

          The Third Note matures on the earlier of April 30, 2000 or the
consummation of the Rollover Transactions. Other than as set forth above,
the Third Note contains terms substantially identical to the Bridge Note
and the New Note, in each case as amended. The Bridge Note, which was
attached as Exhibit 2 to the Schedule 13D filed on November 1, 1999, the
New Note and the Amended Bridge Note, which were attached as Exhibit 4 and
Exhibit 1 to Amendment No. 1 to the Schedule 13D filed on January 5, 2000,
respectively, are incorporated by reference herein in their entirety.

          The Second Letter Agreement amended and superseded the agreement
of the parties regarding the $3 Warrants contained in the Letter Agreement.
Pursuant to the Second Letter Agreement, (i) on the closing date of the
Rollover Transactions (but only if the Company has hired a new Chief
Executive Officer approved by Appaloosa in its sole discretion by that
date), the $3 Warrants will be, at the election of Appaloosa, cancelled and
be of no further force and effect and, simultaneously therewith, the
Company will issue to the Purchasers the Replacement Warrants. If the
Company has not hired a new Chief Executive Officer approved by Appaloosa
in its sole discretion by the closing date of the Rollover Transactions (or
if the Company has hired a new Chief Executive Officer approved by
Appaloosa by the closing date of the Rollover Transactions but Appaloosa
elected not to exchange the $3 Warrants for the Replacement Warrants at
that time), the $3 Warrants shall be exchanged for the Replacement Warrants
six months and one day after the closing date of the Rollover Transactions
(and the Purchasers agree not exercise any of the $3 Warrants during such
period). If the Rollover Transactions are not consummated for any reason,
the $3 Warrants will remain in full force and effect and the terms and
conditions thereof will remain unchanged.

          The Replacement Warrants, if issued, will contain customary
provisions, including anti-dilution protection. In addition, the
Replacement Warrants will contain provisions granting preemptive rights to
the Purchasers in connection with future issuances of debt and equity
securities by the Company. The Replacement Warrants will have an exercise
price of $4.00 per share. Other than as set forth above, the Replacements
Warrants will contain terms substantially identical to the $3 Warrants, the
form of which is attached as Exhibit 3 to the Schedule 13D filed on
November 1, 1999 and is incorporated by reference herein in its entirety.

No. R-1                                          Dated as of April 3, 2000

$2,200,000

FOR VALUE RECEIVED, the undersigned, BIO-PLEXUS, INC. (herein called the
"Company"), a corporation organized and existing under the laws of the
State of Connecticut, hereby unconditionally promises to pay to the order
of Appaloosa Investment Limited Partnership I, or its registered assigns
(the "Holder"), the principal sum of TWO MILLION TWO HUNDRED THOUSAND
DOLLARS ($2,200,000) in immediately available lawful money of the United
States of America, together with interest on the unpaid balance hereof, in
accordance with the terms and conditions set forth below.

     1.   Payment.
          -------

          1.1. Principal. The entire unpaid principal balance of this Note
shall be paid in full by the Company on the Due Date.

          1.2. Home Office Payment. The Company will pay to the Holder or
any transferee thereof all sums becoming due on this Note at the
account/address to be specified by the Holder or transferee for such
purpose by notice to the Company, by wire transfer of immediately available
funds, or at such other address or by such other method as the Holder or
transferee shall have designated by notice to the Company.

          1.3. Prepayment. After all amounts owed under the 7.5% Secured
Note issued by the Company to the Holder on October 21, 1999 (as amended
from time to time, the "7.5% Note") and the 15% Secured Note issued by the
Company to the Holder on January 5, 2000 (as amended from time to time, the
"15% Note") have been repaid in full, subject to Section 8.8, (i) upon at
least ten days prior notice to the Holder, this Note may be prepaid,
without premium or penalty, in whole or in part by the Company at any time
and from time to time and (ii) concurrently with the receipt of any
proceeds received by the Company in respect of any sale of Debentures
pursuant to section 1.4 of the Subscription Agreement, the Company shall
make a mandatory prepayment of the Note in an amount equal to 100% of such
proceeds; provided, that, upon any prepayment under (i) or (ii) above, all
accrued and unpaid interest shall be paid on the principal of the Note
being repaid.

          1.4. Interest. The unpaid principal balance of this Note
outstanding at any time shall accrue interest, at a rate per annum equal to
15% (including during the pendency of any bankruptcy or similar proceeding,
whether or not a claim for post-petition interest is allowed as a claim in
any such bankruptcy or proceeding). Interest shall begin to accrue from the
date hereof and shall be computed on the basis of a year of 360 days and
actual days elapsed and shall be payable in one lump sum on the Due Date.

          1.5. Default Interest. If the Company shall fail to pay any
principal amount of, or interest on, or other amount payable under, this
Note when due and payable (whether at the Due Date, the Acceleration Date
or otherwise), such principal amount, interest or other amount shall
thereafter bear interest, until paid in full (after as well as before
judgment) to the extent lawful, at a rate per annum equal to 15% (including
during the pendency of any bankruptcy or similar proceeding, whether or not
a claim for post-petition interest is allowed as a claim in any such
bankruptcy or proceeding). The Company shall pay such default interest in
cash on demand from time to time.

          1.6. Limitation on Interest. No provision of this Note shall
require the payment or permit the collection of interest in excess of the
maximum rate which is permitted by Law. If any such excess interest is
provided for herein, or shall be adjudicated to be so provided for, then
the Company shall not be obligated to pay such interest in excess of the
maximum rate permitted by Law, and the right to demand payment of any such
excess interest is hereby waived, any other provisions in this Note to the
contrary notwithstanding.

     2.   Deliveries by the Company. Simultaneously with the execution of
this Note, the Company is delivering to the Holder the following:

          (a) an opinion of the Company's counsel, dated as of the date
          hereof, addressed to such Holder in the form of Exhibit 2(a)
          hereto;

          (b) a good standing certificate for the Company, dated no earlier
          than seven days prior to the date hereof, from the State of
          Connecticut;

          (c) a copy of the resolutions of the Board of Directors
          authorizing the execution of each of the Transaction Documents
          and the performance of the transactions contemplated by the
          Transaction Documents, which shall be certified as true, correct
          and effective as of the date hereof by an officer of the Company;
          and

          (d) the Holder's costs and expenses (including the reasonable
          fees and expenses of its counsel, Fried, Frank, Harris, Shriver &
          Jacobson, in an aggregate amount not to exceed $200,000 which
          amounts shall be deducted from the proceeds of this Note and
          shall be wired transferred by the Holder, on behalf of the
          Company, to one or more accounts designated by such party on or
          prior to the date hereof) incurred in connection with the
          transactions contemplated hereby.

     3.   Representations and Warranties of the Company. The Company
represents and warrants to the Holder as follows:

          3.1. Organization; Subsidiaries.(a) The Company is a corporation
duly organized and existing in good standing under the laws of the State of
Connecticut and has the corporate power to own its property and to carry on
its business as now being conducted. The Company is duly qualified as a
foreign corporation to do business and is in good standing in every
jurisdiction in which the nature of the business conducted or property
owned by it makes such qualification necessary and where the failure to so
qualify could, individually or in the aggregate, reasonably be expected to
have a Material Adverse Effect.

               (b) The Company does not have any Subsidiaries. Except as
set forth on Schedule 3.1(b), the Company does not own, directly or
indirectly, or have the right or obligation to acquire, any interest in any
business association or other Person.

          3.2. Due Authorization. (a) The Company has all right, power and
authority to enter into, deliver and perform the Transaction Documents to
which it is a party and to consummate the transactions contemplated
thereby. The execution and delivery of each Transaction Document by the
Company and the performance by it of the transactions contemplated thereby
(including, without limitation, the issuance and sale of this Note) and
compliance by the Company with all the provisions of each Transaction
Document (as applicable) has been duly authorized by all requisite
corporate proceedings on the part of the Company. Each of the Transaction
Documents has been duly executed and delivered on behalf of the Company,
and each such Transaction Document constitutes the legal, valid and binding
obligation of the Company, enforceable against the Company in accordance
with its respective terms, except to the extent that such enforceability
(i) may be limited by bankruptcy, insolvency, reorganization, moratorium or
other similar laws relating to creditors' rights generally or (ii) is
subject to general principles of equity.

               (b) The Board of Directors has taken all necessary action so
that no "fair price," "moratorium," "control share acquisition,"
"interested holder" or other similar anti-takeover statute or regulation
(including, without limitation, Sections 33-840 through 33-845 of the
Connecticut Business Corporation Act) or any applicable anti-takeover
provision in the Company's Certificate of Incorporation or By-Laws is
applicable to the transactions contemplated by the Transaction Documents.
To the knowledge of the Company, no other state takeover statute is
applicable to the transactions contemplated by the Transaction Documents.

          3.3. Capitalization. The authorized capital stock of the Company
consists of (i) 25,000,000 shares of Common Stock, of which, as of the date
hereof, 14,369,746 shares were issued and outstanding, 622,650 shares were
reserved for issuance upon the exercise of outstanding stock options
pursuant to the Company's option plans, 3,958,244 shares were reserved for
issuance upon the exercise of the outstanding warrants, and 1,963,860
shares were reserved for issuance upon the conversion of certain 6%
Convertible Debentures due 2004 and (ii) 3,000,000 shares of Preferred
Stock, no par value (the "Preferred Stock"), of which, as of the date
hereof, no shares were issued and outstanding. All of the outstanding
shares of Common Stock are validly issued and are fully paid and
nonassessable. No class of Capital Stock of the Company is entitled to
preemptive rights. Except as set forth on Schedule 3.3, there are no
outstanding options, warrants, preemptive rights, subscription rights,
calls or commitments of any character whatsoever relating to, or securities
or rights convertible into, shares of any class of Capital Stock of the
Company, or Contracts, by which the Company is or may become bound to issue
additional shares of its Capital Stock or options, warrants or other rights
to purchase or acquire any shares of its Capital Stock. Except as set forth
on Schedule 3.3, no warrants, bonds, debentures, notes or other
Indebtedness or other security having the right to vote (or convertible
into or exercisable for securities having the right to vote) on any matters
on which stockholders may vote were issued or outstanding. Except as set
forth on Schedule 3.3 or as contemplated by the Transaction Documents, the
Company is not a party to, and, to the Company's best knowledge, there are,
and immediately after the Closing, there will be, no agreement, restriction
or encumbrance (such as a preemptive or similar right of first refusal,
right of first offer, proxy, voting agreement, voting trust, registration
rights agreement, shareholders' agreement, etc., whether or not the Company
is a party thereto) with respect to the purchase, sale or voting of any
shares of Capital Stock of the Company (whether outstanding or issuable
upon conversion, exchange or exercise of outstanding securities) or other
securities of the Company pursuant to any provision of Law, the Certificate
of Incorporation or By-Laws, any agreement or otherwise. Except as set
forth on Schedule 3.3, no person has the right to nominate or elect one or
more directors of the Company. Immediately following the transactions
contemplated hereby, the Company's capitalization will be as set forth on
Schedule 3.3. The Company has not declared or paid any dividend or made any
other distribution of cash, stock or other property to its stockholders
since January 1, 1996.

          3.4. SEC Reports Correspondence. The Company has filed all proxy
statements, reports and other documents required to be filed by it under
the Exchange Act from and after January 1, 1995 (collectively, the "SEC
Reports"). Each SEC Report was in compliance in all material respects with
the requirements of its respective report form and did not on the date of
filing contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, and as of the date hereof there is no fact or facts
not disclosed in the SEC Reports which relate specifically to the Company
and which could, individually or in the aggregate, reasonably be expected
to have a Material Adverse Effect.

          3.5. Financial Statements. The financial statements (including
any related schedules and/or notes) included in the SEC Reports have been
prepared in accordance with GAAP consistently followed (except as indicated
in the notes thereto) throughout the periods involved and fairly present
the consolidated financial condition, results of operations, cash flows and
changes in stockholders' equity of the Company as of the respective dates
thereof and for the respective periods then ended (in each case subject, as
to interim statements, to changes resulting from year-end adjustments, none
of which were material in amount or effect). Except as set forth on
Schedule 3.5, the Company is not subject to any Liabilities, except (i)
Liabilities in the respective amounts reflected or reserved against in the
Company's balance sheet as of December 31, 1998 included in the SEC Reports
or (ii) Liabilities incurred in the ordinary course of business since
December 31, 1998 which could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

          3.6. No Material Adverse Change. Since December 31, 1998, no
event has occurred or failed to occur which could, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect.

          3.7. Intellectual Property Rights. Schedule 3.7 sets forth a
complete and correct list of all Intellectual Property of the Company (the
"Company Intellectual Property"). Except as set forth on Schedule 3.7, the
Company owns and possesses all right, title and interest in, or possesses
adequate licenses to (without the making of any payment to others or the
obligation to grant rights to others in exchange) all the Company
Intellectual Property, free and clear of any Liens, licenses or other
restrictions. The Company has the right to require the applicant of any
Company Intellectual Property which is an application, including but not
limited to patent applications, trademark applications, service mark
applications, copyright applications, or mask work applications, to
transfer ownership to the Company of the application and of the
registration once it issues. All registered patents, trademarks, service
marks and copyrights listed on Schedule 3.7 are valid and subsisting and in
full force and effect. The Company Intellectual Property is all the
Intellectual Property that is necessary for the ownership, maintenance and
operation of the Company's properties and assets and the Company has the
right to use all of the Company Intellectual Property in all jurisdictions
in which the Company conducts or proposes to conduct its business, and the
consummation of the transactions contemplated hereby will not alter or
impair any such rights. The Company has never agreed to indemnify any
person for or against any interference, infringement, misappropriation or
other conflict with respect to any Company Intellectual Property. Except as
set forth in Schedule 3.7, no third party has interfered with, infringed
upon, misappropriated or otherwise come into conflict with any Company
Intellectual Property. The Company has taken all reasonably necessary and
desirable action to maintain and protect each item of Company Intellectual
Property. The validity, ownership, enforceability, use or legality of the
Company Intellectual Property is not being questioned or opposed in any
Litigation or Order to which the Company or any Person who has granted a
license of Intellectual Property to the Company, is a party or subject,
nor, to the knowledge of the Company, is any such Litigation or Order
threatened. The conduct of the Company as currently conducted and as
currently proposed to be conducted does not and will not infringe,
interfere with, misappropriate or otherwise come into conflict with any
Intellectual Property of any other Person, and the Company has not received
any charge, complaint, claim, demand or notice alleging any such
infringement, interference, misappropriation or conflict (including any
claim that the Company must license or refrain from using any Intellectual
Property of any other Person). Except as set forth on Schedule 3.7, the
Company has not granted any licenses of Intellectual Property to any
Person.

          3.8. Existing Indebtedness; Future Liens. (a) Schedule 3.8 sets
forth a complete and correct list of all outstanding Indebtedness of the
Company as of the date hereof. Except as set forth on Schedule 3.8, the
Company has not defaulted and no waiver of default is currently in effect,
in the payment of any principal or interest on any such Indebtedness and no
event or condition exists with respect to any such Indebtedness that would
permit (or that with notice or the lapse of time, or both, would permit)
one or more Persons to cause such Indebtedness to become due and payable
before its stated maturity or before its regularly scheduled dates of
payment. The Company has not received any notice from any Person declaring
or threatening to declare any Indebtedness owed by the Company to such
Person due and payable prior to the stated maturity of such Indebtedness or
before its regularly scheduled dates of payment.

               (b) The Company has not agreed or consented to cause or
permit in the future (upon the happening of a contingency or otherwise) any
of its property, whether now owned or hereafter acquired, to be subject to
any Lien (other than Permitted Liens).

          3.9. Litigation. (a) Except as set forth on Schedule 3.9, there
is no Litigation pending or, to the knowledge of the Company, threatened
against the Company or any of its properties or assets by or before any
court, arbitrator or other Governmental Entity.

               (b) The Company is not in default under or in breach of any
Order of any court, arbitrator or other Governmental Entity, and the
Company is not subject to or a party to any Order of any court, arbitrator
or other Governmental Entity arising out of any claim, demand, notice,
action, suit or proceeding under any Law.

          3.10. Compliance with Laws. The Company is in compliance with all
applicable Laws including, without limitation, all rules, regulations and
other Laws of the Food and Drug Administration relating to the design,
development, manufacturing, sales and distribution of safety medical
products and accessories, except where the failure to comply could not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect. No Order has been issued nor any Law enacted which
prevents, nor does any Law prohibit the consummation of the transactions
contemplated by any of the Transaction Documents.

          3.11. Offering of the Securities. In connection with the offering
of this Note, neither the Company nor any Person acting on its behalf has
offered the Note, or any similar securities of the Company for sale to,
solicited any offers to buy the Note, or any similar securities of the
Company from or otherwise approached or negotiated with respect to the
Company with any Person other than the Purchasers and other "accredited
investors" (as defined in Rule 501(a) under the Securities Act). Neither
the Company nor any Person acting on its behalf has taken or, except as
contemplated hereby will take any action (including, without limitation,
any offering of any securities of the Company under circumstances which
would require the integration of such offering with the offering of the
Note under the Securities Act) which could reasonably be expected to
subject the offering, issuance or sale of the Note and the Warrants to the
registration requirements of Section 5 of the Securities Act or violate the
provisions of any securities, "blue sky", or similar law of any applicable
jurisdiction.

          3.12. Solvency. The Company is not, and after giving effect to
the issuance of this Note and the application of the proceeds therefrom
will not be, insolvent within the meaning of Title 11 of the United States
Code or any comparable state law provision.

          3.13. Security Documents. Except as set forth in Schedule 3.13,
upon proper filing of the Financing Statements (or assignments thereof) in
the offices of the Secretary of State of Connecticut with respect to the
Company (or assignments thereof) and in the locations identified in the
Security Agreement, the Liens granted under the Transaction Documents shall
constitute a fully perfected first priority security interest in all right,
title and interest of the Company in and to the personal property therein
prior to any other security interests against such property or interests
therein.

          3.14. Disclosure. Neither any Transaction Document nor any
Schedule hereto and thereto, nor any certificate furnished to any Holder by
or on behalf of the Company in connection with the transactions
contemplated hereby and thereby, contains any untrue statement of a
material fact or omits to state a material fact necessary in order to make
the statements contained herein and therein not misleading. The financial
forecasts furnished by the Company to the Holder has been prepared in good
faith based upon reasonable assumptions. There is no fact or information
relating to the Company that could reasonably be expected to be material to
the Company that has not been disclosed to the Holder.

     4.   Covenants of the Company. The Company covenants that for so long as
this Note is outstanding or any amounts are due and unpaid hereunder:

          4.1. Limitation on Indebtedness. The Company shall not, and shall
not permit any of its Subsidiaries to, create, incur, assume or directly or
indirectly guarantee or in any other manner become directly or indirectly
liable for the payment of any Indebtedness (excluding Permitted
Indebtedness and Indebtedness which is a Guaranty of an Indebtedness of the
Company or any of its Subsidiaries that is otherwise Permitted
Indebtedness).

          4.2. Limitation on Encumbrances. The Company shall not, and shall
not permit any of its Subsidiaries to, directly or indirectly, create,
incur, assume or otherwise suffer to exist or cause or otherwise suffer to
become effective any Lien in or on any right, title or interest to any
property (real or personal) that constitutes all or any portion of the
Collateral (a "Restricted Encumbrance," which term excludes the Lien
created in favor of the Holder) unless such Restricted Encumbrance is a
Permitted Lien.

          4.3. Limitation on Dividends; Stock Issuances. The Company shall
not offer or issue any shares of Preferred Stock or Common Stock for any
purpose whatsoever, except pursuant to Schedule 4.3. The Company shall not
declare any dividends on any shares of its Capital Stock, or make any
payment on account of, or set apart assets for a sinking or other analogous
fund for, the purchase, redemption, retirement, exchange or other
acquisition of any shares of its Capital Stock, whether now or hereafter
outstanding, or make any other distribution in respect thereof, either
directly or indirectly, whether in cash, securities, property or in
obligations of the Company or any of its Subsidiaries.

          4.4. Stockholders' Meetings. As promptly as practicable hereafter
but in no event later than April 30, 2000, the Company shall take all
action necessary, in accordance with applicable Law and its Certificate of
Incorporation and By-laws, to convene a special meeting of its stockholders
(the "Company Meeting") for the purpose of considering and voting upon the
approval of the Rollover Transactions, including, without limitation, the
issuance and sale of the Convertible Notes, the Shares and the Rollover
Warrants, and any other transactions contemplated in furtherance thereof
under applicable Law; provided, however, that the Company shall adjourn the
Company Meeting from time to time until all of the conditions set forth in
Section 6.2 are satisfied or waived (other than those conditions that by
their nature are to be satisfied on the Rollover Date), such that the
Company Meeting shall take place on the same day as the Rollover Date in
accordance with Section 6.1. The Company will use its best efforts to
obtain such stockholders' approval, including, without limitation, taking
all lawful actions to solicit such approval. The Board of Directors will
recommend that its stockholders vote in favor of and approve the Rollover
Transactions, including, without limitation, the issuance and sale of the

Liabilities and out-of-pocket expenses (including reasonable attorneys'
fees and disbursements and other costs of investigation or defense,
including those incurred upon any appeal) which may be instituted or

in connection with or arising out of the transactions contemplated
hereunder and thereunder and any actions or failures to act in connection

                    (ii) Upon receipt by any Indemnified Person of any
Action against such Indemnified Person with respect to which indemnity may

counsel under this Note or any other Transaction Document, the Company
shall not in such event be responsible hereunder for the fees and expenses
of more than one firm of separate counsel in connection with any Action in
the same jurisdiction, in addition to any local counsel. In addition, the

settle, compromise or consent to the entry of any judgment in or otherwise
seek to terminate any pending or threatened Action in which indemnification
may be sought hereunder (whether or not any Indemnified Person is a party
thereto) unless such settlement, compromise, consent or termination
includes an unconditional release of such Indemnified Person from all
liabilities and expenses arising out of such Action.

               (c) The Company shall bear all sales, documentary, transfer,
stamp or other similar taxes and all filing fees and expenses incurred in
connection with the transactions contemplated by this Note and shall
indemnify and hold harmless each Indemnified Purchaser from and against any
such taxes.

          8.2. Severability. If any term, provision, covenant or
restriction of this Note or any exhibit hereto is held by a court of
competent jurisdiction to be invalid, void or unenforceable, the remainder
of the terms, provisions, covenants and restrictions of this Note and such
exhibits shall remain in full force and effect and shall in no way be
affected, impaired or invalidated. It is hereby stipulated and declared to
be the intention of the parties that they would have executed the remaining
terms, provisions, covenants and restrictions without including any of such
which may be hereafter declared invalid, void or unenforceable.

          8.3. Specific Enforcement. The Holder, on the one hand, and the
Company, on the other, acknowledge and agree that irreparable damage would
occur in the event that any of the provisions of this Note were not
performed in accordance with their specific terms or were otherwise
breached. It is accordingly agreed that the Holder shall be entitled to an
injunction to prevent breaches of the provisions of this Note and to
enforce specifically the terms and provisions hereof in any court of the
United States or any state thereof having jurisdiction, this being in
addition to any other remedy to which they may be entitled at Law or
equity.

Schedules and Exhibits hereto and thereto) contain the entire understanding
of the parties with respect to the transactions contemplated hereby and

Attention:  Mr. James Bolin

Dear Mr. Bolin:

          Reference is made to the 7.5% Secured Note, dated October 21,
1999, issued by Bio-Plexus, Inc. (the "Company") to Appaloosa Investment
Limited Partnership I ("Appaloosa") (as such 7.5% Secured Note may be
amended and restated from time to time, the "7.5% Note"), the 15% Secured
Note, dated January 5, 2000, issued by the Company to Appaloosa (as such
15% Secured Note may be amended and restated from time to time, the "15%
Note"), and the side letter, dated December 30, 1999, between the Company
and Appaloosa (the "First Side Letter"). The purpose of this letter is to
set forth the understanding of the Company and Appaloosa with respect to
the matters set forth herein:

          (a)  on the date hereof, the Company and Appaloosa will enter
               into a second amendment to the 7.5% Note in the form
               attached hereto as Exhibit A;

          (b)  on the date hereof, the Company and Appaloosa will enter
               into a first amendment to the 15% Note in the form attached
               hereto as Exhibit B;

          (c)  on the date hereof, the Company and Appaloosa will enter
               into the 15% Secured Note in the form attached hereto as
               Exhibit C (the "Third Bridge Note"); and

          (d)  paragraph (d) of the First Side Letter is hereby amended by
               deleting it in its entirety and substituting in lieu thereof
               the following:

                    (d) (i) On the closing date of the Rollover
               Transactions (but only if the Company has hired a new Chief
               Executive Officer approved by Appaloosa in its sole
               discretion by that date), the $3 Warrants (as defined in the
               7.5% Note) will be, at the election of Appaloosa, cancelled
               and be of no further force and effect and, simultaneously
               therewith, the Company will issue to one or more affiliates
               of Appaloosa replacement warrants to purchase 1,000,000
               shares of Common Stock with an exercise price of $4 per
               share in the form attached hereto as Exhibit D (if so
               issued, the "Warrants"). If the Company has not hired a new
               Chief Executive Officer approved by Appaloosa in its sole
               discretion by the closing date of the Rollover Transactions
               (or if the Company has hired a new Chief Executive Officer
               approved by Appaloosa by the closing date of the Rollover
               Transactions but Appaloosa elected not to exchange the $3
               Warrants for the Warrants at that time), the $3 Warrants
               shall be exchanged for the Warrants six months and one day
               after the closing date of the Rollover Transactions (and
               Appaloosa hereby agrees not to exercise any of the $3
               Warrants during such period).

               (ii) If the Rollover Transactions are not consummated for
               any reason, the $3 Warrants (as defined in the 7.5% Note)
               will remain in full force and effect and the terms and
               conditions thereof will remain unchanged.

          The Company represents that (i) the execution and delivery of
this letter by the Company and the performance by it of the transactions
contemplated hereby (including, without limitation, the issuance of the
Warrants and issuance of shares of Common Stock (as defined in the 7.5%
Note) upon exercise of the Warrants) and compliance by the Company with all
the provisions of the Warrants (as applicable) have been duly authorized by
all requisite corporate proceedings on the part of the Company and (ii) the
shares of Common Stock issuable upon exercise of the Warrants have been
validly reserved for issuance, and upon issuance, will be validly issued
and outstanding, fully paid and nonassessable.

          The Company cannot assign its rights and obligations under this
letter without the written consent of Appaloosa.

          Appaloosa represents that (a) it is acquiring the Third Bridge
Note for its own account for the purpose of investment and not with a view
to or for sale in connection with any distribution thereof except in
compliance with all applicable securities law and (b) it is an "accredited
investor" within the meaning of Rule 501 promulgated under the Securities
Act of 1933, as amended.

          If any term, provision, covenant or restriction of this letter or
any exhibit hereto is held by a court of competent jurisdiction to be
invalid, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions of this letter and such exhibits shall remain in
full force and effect and shall in no way be affected, impaired or
invalidated. It is hereby stipulated and declared to be the intention of
the parties that they would have executed the remaining terms, provisions,
covenants and restrictions without including any of such which may be
hereafter declared invalid, void or unenforceable.

          Appaloosa, on the one hand, and the Company, on the other,
acknowledge and agree that irreparable damage would occur in the event that
any of the provisions of this letter were not performed in accordance with
their specific terms or were otherwise breached. It is accordingly agreed
that Appaloosa shall be entitled to an injunction to prevent breaches of
the provisions of this letter and to enforce specifically the terms and
provisions hereof in any court of the United States or any state thereof
having jurisdiction, this being in addition to any other remedy to which
they may be entitled at Law (as defined in the 7.5% Note) or equity.

          Neither the Company nor Appaloosa shall make any public
statements, including, without limitation, any press releases, with respect
to this letter and the transactions contemplated hereby without the prior
written consent of the other party (which consent shall not be unreasonably
withheld) except as may be required by Law. If a public statement is
required to be made by Law, the parties shall consult with each other in
advance as to the contents and timing thereof.

          This letter shall not constitute an amendment of any other
provisions of the First Side Letter not expressly referred to herein and
shall not be construed as a waiver or consent to any further or future
action on the part of the Company that would require a waiver or consent of
the Holder. Except as expressly amended hereby, the provisions of the First
Side Letter shall remain in full force and effect.

          THIS LETTER SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH,
AND THE RIGHTS OF THE PARTIES SHALL BE GOVERNED BY, THE LAW OF THE STATE OF
NEW YORK EXCLUDING CHOICE-OF-LAW PRINCIPLES OF THE LAW OF SUCH STATE THAT
WOULD REQUIRE THE APPLICATION OF THE LAWS OF A JURISDICTION OTHER THAN SUCH
STATE.

          If any Litigation (as defined in the 7.5% Note) shall be brought
by Appaloosa in order to enforce any right or remedy under this letter, the
Company hereby consents and will submit to the jurisdiction of any state or
federal court of competent jurisdiction sitting within the area comprising
the Southern District of New York on the date of this letter. The Company
hereby irrevocably waives any objection, including, but not limited to, any
objection to the laying of venue or based on the grounds of forum non
conveniens, which it may now or hereafter have to the bringing of any such
Litigation in such jurisdiction.

          THE COMPANY HEREBY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN RESPECT OF ANY ACTION, PROCEEDING OR LITIGATION DIRECTLY OR
INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH, THIS LETTER.
