THIS SUBORDINATION AGREEMENT dated February 20, 2007, is made and executed among
BIOMEIRICA, INC.; 1533 MONROVIA AVENUE; NEWPORT BEACH, CA 92663 ("Borrower");
JANET MOORE, Trustee of THE JANET MOORE TRUST DATED AUGUST 21, 1998 under the
provisions of a trust agreement dated August 21, 1998; and JANET MOORE,
Individually; 1533 MONROVIA AVENUE; NEWPORT BEACH, CA 92663 ("Creditor"); and
COMMERCIAL BANK OF CALIFORNIA, 695 TOWN CENTER DRIVE, SUITE 100, COSTA MESA, CA
92626 ("Lender").

REQUESTED FINANCIAL ACCOMMODATIONS. Creditor and Borrower each want Lender to
provide financial accommodations to Borrower in the form of (A) new credit or
loan advances, (B) an extension of time to pay or other compromises regarding
all or part of Borrower's present indebtedness to Lender, or (C) other benefits
to Borrower. Borrower and Creditor each represent and acknowledge to Lender that
Creditor will benefit as a result of these financial accommodations from Lender
to Borrower, and Creditor acknowledges receipt of valuable consideration for
entering into this Agreement. Based on the representations and acknowledgments
contained in this Agreement, Borrower and Creditor agree with Lender as follows:

SUBORDINATED INDEBTEDNESS. The words "Subordinated Indebtedness" as used in this
Agreement mean the following specific indebtedness from Borrower to Creditor,
including all renewals, extensions, modifications and substitutions for the
indebtedness, including principal, interest, and all costs and attorneys' fees,
relating to the indebtedness: $234,426.00.

SUPERIOR INDEBTEDNESS. The words "Superior Indebtedness" as used in this
Agreement mean and include all present and future indebtedness, obligations,
liabilities, claims, rights, and demands of any kind which may be now or
hereafter owing from Borrower to Lender. The term "Superior Indebtedness" is
used in its broadest sense and includes without limitation all principal, all
interest, all costs, attorneys' fees, all sums paid for the purpose of
protecting Lender's rights in security (such as paying for insurance on
collateral if the owner fails to do so), all contingent obligations of Borrower
(such as a guaranty), all obligations arising by reason of Borrower's accounts
with Lender (such as an overdraft on a checking account), and all other
obligations of Borrower to Lender, secured or unsecured, of any nature
whatsoever.

SUBORDINATION. All Subordinated Indebtedness of Borrower to Creditor is and
shall be subordinated in all respects to all Superior Indebtedness of Borrower
to Lender. If Creditor holds one or more Security Interests, whether now
existing or hereafter acquired, in any of Borrower's real property or personal
property, Creditor also subordinates all Creditor's Security Interests to all
Security Interests held by Lender, whether now existing or hereafter acquired.

PAYMENTS TO CREDITOR. Borrower will not make and Creditor will not accept, at
any time while any Superior Indebtedness is owing to Lender, (A) any payment
upon any Subordinated Indebtedness, (B) any advance, transfer, or assignment of
assets to Creditor in any form whatsoever that would reduce at any time or in
any way the amount of Subordinated Indebtedness, or (C) any transfer of any
assets as security for the Subordinated Indebtedness, except upon Lender's prior
written consent.

In the event of any distribution, division, or application, whether partial or
complete, voluntary or involuntary, by operation of law or otherwise, of all or
any part of Borrower's assets, or the proceeds of Borrower's assets, in whatever
form, to creditors of Borrower or upon any indebtedness of Borrower, whether by
reason of the liquidation, dissolution or other winding-up of Borrower, or by
reason of any execution sale, receivership, insolvency, or bankruptcy
proceeding, assignment for the benefit of creditors, proceedings for
reorganization, or readjustment of Borrower or Borrower's properties, then and
in such event, (A) the Superior Indebtedness shall be paid in full before any
payment is made upon the Subordinated Indebtedness, and (B) all payments and
distributions, of any kind or character and whether in cash, property, or
securities, which shall be payable or deliverable upon or in respect of the
Subordinated Indebtedness shall be paid or delivered directly to Lender for
application in payment of the amounts then due on the Superior Indebtedness
until the Superior Indebtedness shall have been paid in full.

In order that Lender may establish its right to prove claims and recover for its
own account dividends based on the Subordinated Indebtedness, Creditor does
hereby assign all its right, title, and interest in such claims to Lender.
Creditor further agrees to supply such information and evidence, provide access
to and copies of such of Creditor's records as may pertain to the Subordinated
Indebtedness, and execute such instruments as may be required by Lender to
enable Lender to enforce all such claims and collect all dividends, payments, or
other disbursements which may be made on account of the Subordinated
Indebtedness. For such purposes, Creditor hereby irrevocably authorizes Lender
in its discretion to make and present for or on behalf of Creditor such proofs
of claims on account of the Subordinated Indebtedness as Lender may deem
expedient and proper and to vote such claims in any such proceeding and to
receive and collect any and all dividends, payments, or other disbursements made
thereon in whatever form the same may be paid or issued and to apply the same on
account of the Superior Indebtedness.

Should any payment, distribution, security, or proceeds thereof be received by
Creditor at any time on the Subordinated Indebtedness contrary to the terms of
this Agreement, Creditor immediately will deliver the same to Lender in
precisely the form received (except for the endorsement or assignment of
Creditor if necessary), for application on or to secure the Superior
Indebtedness, whether it is due or not due, arid until so delivered the same
shall be held in trust by Creditor as property of Lender. In the event Creditor
fails to make any such endorsement or assignment, Lender, or any of its officers
on behalf of Lender, is hereby irrevocably authorized by Creditor to make the
same.

CREDITOR'S NOTES. Creditor agrees to deliver to Lender, at Lender's request, all
notes of Borrower to Creditor, or other evidence of the Subordinated
Indebtedness, now held or hereafter acquired by Creditor, while this Agreement
remains in effect. At Lender's request, Borrower also will execute and deliver
to Creditor a promissory note evidencing any book account or claim now or
hereafter owed by Borrower to Creditor, which note also shall be delivered by
Creditor to Lender. Creditor agrees not to sell, assign, pledge or otherwise
transfer any of such notes except subject to all the terms and conditions of
this Agreement.

CREDITOR'S REPRESENTATIONS AND WARRANTIES. Creditor represents and warrants to
Lender that: (A) no representations or agreements of any kind have been made to
Creditor which would limit or qualify in any way the terms of this Agreement;
(B) this Agreement is executed at Borrower's request and not at the request of
Lender; (C) Lender has made no representation to Creditor as to the
creditworthiness of Borrower; and (D) Creditor has established adequate means of
obtaining from Borrower on a continuing basis information regarding Borrower's
financial condition. Creditor agrees to keep adequately informed from such means
of any facts, events, or circumstances which might in any way affect Creditor's
risks under this Agreement, and Creditor further agrees that Lender shall have
no obligation to disclose to Creditor information or material acquired by Lender
in the course of its relationship with Borrower.

extend, renew, or modify any loan to I3orrower or to grant any other financial
accommodations to Borrower whatsoever; (B) to make any presentment, protest,

resort for payment or to proceed directly or at once against any person,
including Borrower; (D) to proceed directly against or exhaust any Security
Interests held by Lender from Borrower, any other guarantor, or any other
person; (E) to pursue any other remedy within Lender's power; or (F) to commit
any act or omission of any kind, at any time, with respect to any matter
whatsoever.

Superior Indebtedness or any Security Interests for the Superior Indebtedness
without affecting whatsoever any of Lender's rights under this Agreement. In
particular, without limitation, Lender may, without notice of any kind to
Creditor, (A) make one or more additional secured or unsecured loans to
Borrower; (B) repeatedly alter, compromise, renew, extend, accelerate, or

OTHER TERMS AND CONDITIONS. The following provisions are a part of this

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of

     Amendments. This Agreement, together with any Related Documents,
     constitutes the entire understanding and agreement of the parties as to the
     matters set forth in this Agreement. No alteration of or amendment to this
     Agreement shall be effective unless given in writing and signed by the
     party or parties sought to be charged or bound by the alteration or
     amendment.

     Arbitration. Borrower and Creditor and Lender agree that all disputes,
     claims and controversies between them whether individual, joint, or class
     in nature, arising from this Agreement or otherwise, including without
     limitation contract and tort disputes, shall be arbitrated pursuant to the
     Rules of the American Arbitration Association in effect at the time the
     claim is filed, upon request of either party. No act to take or dispose of
     any Collateral shall constitute a waiver of this arbitration agreement or
     be prohibited by this arbitration agreement. This includes, without
     limitation, obtaining injunctive relief or a temporary restraining order;
     invoking a power of sale under any deed of trust or mortgage; obtaining a
     writ of attachment or imposition of a receiver; or exercising any rights
     relating to personal property, including taking or disposing of such
     property with or without judicial process pursuant to Article 9 of the
     Uniform Commercial Code. Any disputes, claims, or controversies concerning
     the lawfulness or reasonableness of any act, or exercise of any right,
     concerning any Collateral, including any claim to rescind, reform, or
     otherwise modify any agreement relating to the Collateral, shall also be
     arbitrated, provided however that no arbitrator shall have the right or the
     power to enjoin or restrain any act of any party. Borrower and Creditor and
     Lender agree that in the event of an action for judicial foreclosure
     pursuant to California Code of Civil Procedure Section 726, or any similar
     provision in any other state, the commencement of such an action will not
     constitute a waiver of the right to arbitrate and the court shall refer to
     arbitration as much of such action, including counterclaims, as lawfully
     may be referred to arbitration. Judgment upon any award rendered by any
     arbitrator may be entered in any court having jurisdiction. Nothing in this
     Agreement shall preclude any party from seeking equitable relief from a
     court of competent jurisdiction. The statute of limitations, estoppel,
     waiver, laches, and similar doctrines which would otherwise be applicable
     in an action brought by a party shall be applicable in any arbitration
     proceeding, and the commencement of an arbitration proceeding shall be
     deemed the commencement of an action for these purposes. The Federal
     Arbitration Act shall apply to the construction, interpretation, and
     enforcement of this arbitration provision.

     Attorneys' Fees; Expenses. Creditor agrees to pay upon demand elf of
     Lender's costs and expenses, including Lender's attorneys' fees and
     Lender's legal expenses, incurred in connection with the enforcement of

     Agreement, and Creditor shall pay the costs and expenses of such
     enforcement. Costs and expenses include Lender's attorneys' fees and legal
     expenses whether or not there is a lawsuit, including attorneys' fees and
     legal expenses for bankruptcy proceedings (including efforts to modify or

     post-judgment collection services. Creditor also shall pay all court costs
     and such additional fees as may be directed by the court.

     represents and warrants that he or she has authority to execute this

     Creditor's security interests in Creditor's property, if any.

     Caption Headings. Caption headings in this Agreement are for convenience
     purposes only and are not to be used to interpret or define the provisions
     of this Agreement.

     State of California without regard to its conflicts of law provisions. This
     Agreement has been accepted by Lender in the State of California.

     Choice of Venue. If there is a lawsuit, Creditor agrees upon Lender's
     request to submit to the jurisdiction of the courts of ORANGE County, State

     interest therein, and this Agreement shall be transferable to the same
     extent and with the same force and effect as any such Indebtedness may be
     transferable.

     No Waiver by Lender. Lender shall not be deemed to have waived any rights
     under this Agreement unless such waiver is given in writing and signed by
     Lender. No delay or omission on the part of Lender in exercising any right
     shall operate as a waiver of such right or any other right. A waiver by
     Lender of a provision of this Agreement shall not prejudice or constitute a
     waiver of Lender's right otherwise to demand strict compliance with that
     provision or any other provision of this Agreement: No prior waiver by
     Lender, nor any course of dealing between Lender and Creditor, shall
     constitute a waiver of any of Lender's rights or of any of Creditor's
     obligations as to any future transactions. Whenever the consent of Lender
     is required under this Agreement, the granting of such consent by Lender in
     any instance shall not constitute continuing consent to subsequent

     be granted or withheld in the sole discretion of Lender.
