security interests in specific items of Equipment; (ii) leases of specific items
of Equipment; (iii) liens for taxes, fees, assessments or other governmental

         2.       Loans and Payments.

                  (a)      Loans. Lender shall, at Borrower's request, make one
or more loans (each, a "Loan" and collectively, the "Loans") to Borrower, from
time to time in total principal amount of not more than $250,000.00. Each Loan
shall be in an amount of not more than $50,000.00, or such greater amount as
mutually agreed by Lender and Borrower. All requests for Loans shall be made to
Lender no later than November 15, 2003, any Lender shall have no obligation to
make any Loans for any requests received by it after such date. As of the date
hereof, Lender is making an initial Loan to Borrower in the principal sum of
$50,000.00. Requests for Loans shall be in writing and submitted by Borrower to
Lender at least three business days prior to the date the Loan is to be made.

                  (b)      Interest. The Loans shall accrue interest at the rate
of 17.64% per annum. Interest shall be calculated on the basis of a 365/366-day
year for the actual number of days elapsed.

                  (c)      Maturity Date; Extension. All amounts outstanding
hereunder are due and payable on August 5, 2006 (the "Maturity Date"). Lender
may extend the Maturity Date in its sole discretion.

                  (d)      Payments; Prepayments. Payments of principal and
interest on the Loans shall be amortized over 36 months, with a balloon payment
of $30,000.00 principal due on the Maturity Date. The

amortization schedule for the initial Loan being made hereunder is attached to
this Agreement as Exhibit B. Each time that Lender makes a Loan to Borrower,
Lender and Borrower shall review and update the amortization schedule to include
all outstanding Loans. Payments on the Loans shall be due and payable on the
15th day of each month, provided, that Borrower will be allowed a five day grace
period on payment due. For any payments more than five days past due, such
payment shall also accrue a late fee equal to five percent (5%) of the amount of
such late payment, and such late fee shall be immediately due and payable by
Borrower to Lender as additional Obligations hereunder. Borrower may prepay the
Loans in full at any time without premium or penalty, upon payment of the entire
then-remaining principal amount (as reflected on the amortization schedule) plus
any accrued and unpaid interest through the date of repayment. Borrower shall
not make any partial prepayments on the Loans.

                  (e)      Conditions Precedent to Loans. Notwithstanding any
provisions herein to the contrary, Loans will not be made hereunder until the

                  8.       Most recent audited financial statements of Pacific

         3.       Security Interest. Borrower grants Lender a first priority
security interest in the Collateral to secure Borrower's timely payment and
performance of the Obligations. Borrower agrees to promptly execute and deliver
or cause to be executed and delivered to Lender and Lender is hereby authorized
to record or file, any statement and/or instrument requested by Lender for the
purpose of showing Lender's security interest in the Collateral, including
without limitation, financing statements and security agreements. Borrower
hereby appoints Lender as Borrower's limited attorney-in-fact to execute and
record all documents necessary to perfect or maintain the perfection of Lender's
security interests hereunder or to make claim for, receive payment of, and
execute and endorse all documents, checks or drafts for loss or damage under any
insurance policy.

         4.       Representations and Warranties. Borrower represents and

10-KSB, 10-QSB and 8-K filed from time to time with the U.S. Securities Exchange
Commission by Pacific Biometrics Inc.:

                  (a)      Financial Statements. (i) All applications, financial
statements and reports which have been submitted by Borrower to Lender are, and
all information hereafter furnished by Borrower to Lender will be, true and
correct in all material respects as of the date submitted; (ii) as of the date
hereof, there has been no material adverse change in any matter stated in such
applications, financial statements and reports except as otherwise disclosed to
Lender; (iii) none of the foregoing omit or omitted to state any material fact
necessary to make such statements made to Lender not misleading at the time
made.

                  (b)      Organization. Borrower is a corporation duly
organized and validly existing in the State of Washington, and is duly qualified
to do business and is in good standing in each State in which the Equipment will
be located, except where the failure to be qualified or in good standing would
not have a material adverse effect on the business and operations of Borrower.

                  (c)      Authority. Borrower has full power, authority and
right to own and/or lease property and to execute, deliver and perform this
Agreement, and the execution, delivery and performance hereof has been
authorized by all necessary action of Borrower.

<PAGE>

                  (d)      Enforceability. This Agreement and any other document
executed in connection herewith has been duly executed and delivered by Borrower
and constitutes a legal, valid and binding obligation of Borrower enforceable
against it in accordance with its terms.

                  (e)      Consents. The execution, delivery and performance of
this Agreement does not require any approval or consent of any stockholders,
partners or proprietors or of any trustee or holders of any indebtedness or
obligations of Borrower, and will not contravene any law, regulation, judgment
or decree applicable to Borrower, or the articles of incorporation, by-laws or
other governing documents of Borrower, or contravene the provisions of, or
constitute a default under, or result in the creation of any lien upon any
property of Borrower under any mortgage, instrument or other agreement to which
Borrower is a party or by which Borrower or its assets may be bound or affected
(except for the security interest created hereby). Except as disclosed or
contemplated by this Agreement, no authorization, approval, license, filing or
registration with any court or governmental agency or instrumentality is
necessary in connection with the execution, delivery, performance, validity and
enforceability of this Agreement.

                  (f)      Title. Borrower has good and marketable title to the
Equipment, free and clear of all liens other than Permitted Liens. No party has
a security interest in the Equipment, other than Permitted Liens, and the
Equipment is and shall at all times remain personal property regardless of how
it may be affixed to any real property.

                  (g)      Litigation. There is no action, suit, investigation
or proceeding by or before any court, arbitrator, agency or governmental
authority pending or, to the knowledge of Borrower, threatened against or
affecting Borrower (i) which involves the Equipment or the transactions
contemplated by this Agreement, or (ii) which, if adversely determined, could
have a material adverse effect on the financial condition, business or operation
of Borrower.

         5.       Covenants of Borrower.

                  (a)      Insurance. Until the Loans are paid in full, Borrower
shall, at its own expense, keep the Equipment insured against risks of loss or
damage in such amounts (but in no event less than the remaining outstanding
balance due on the Loans and with a deductible amount not to exceed $10,000.00)
and in such form as is reasonably satisfactory to Lender. All such insurance
policies shall name Lender and Lender's assignee(s) as principal loss payees as
their interests may appear. Borrower shall also, at its own expense, carry
public liability insurance, with Lender and Lender's assignee(s) named as an
additional insured, in such amounts with such companies and in such form as is
reasonably satisfactory to Lender, with respect to injury to person or property
resulting from or based in any way upon or in any way connected with or relating
to the installation, use or alleged use, or operation of any or all of the
Equipment, or its location or condition. Not less than 30 days following the
date hereof, Borrower shall deliver to Lender satisfactory evidence of such
insurance and shall further deliver evidence of renewal of each such policy not
less than 30 days prior to expiration thereof. Each such policy shall contain an
endorsement providing that the insurer will give Lender and its assignees not
less than 30 days' prior written notice of the effective date of any alteration,
change, cancellation, or modification of such policy or the failure by Borrower
to timely pay all required premiums, costs or charges with respect thereto. Upon
Lender's request, Borrower shall cause its insurance agent(s) to execute and
deliver to Lender Loss Payable Clause Endorsement and Additional Insured
Endorsement (bodily injury and property damage liability insurance) forms
provided to Borrower to Lender and name any assignees of Lender designated by
Lender. Each policy shall be primary without rights of contribution from any
other insurance which is carried by Lender and shall expressly provide that all
of the provisions thereof, except the limits of liability, shall operate in the
same manner as if there were a separate policy covering each insured. Each
policy shall provide for payment to Lender and its assignees notwithstanding any
action, inaction or breach of representation or warranty by Borrower or Lender.
In case of the failure to procure or maintain such insurance, Lender shall have
the right, but not the obligation, to obtain such insurance and there shall be
no recourse against Lender or its assignees for payment of such premiums or
other amounts with respect thereto. Any premium paid by Lender shall be
immediately due and payable by Borrower to Lender as additional Obligations
hereunder. The maintenance of any policy or policies of insurance pursuant to
this Section shall not limit any obligation or liability of Borrower pursuant to
any provision of this Agreement. Borrower shall, to the extent reasonably
possible, obtain liability insurance required hereunder on an occurrence basis
rather than a claims-made basis. To the extent that Borrower must obtain some or
all of this coverage on a claims-made basis, Borrower shall provide Lender with
satisfactory evidence that the retroactive date of the claims-

                                      -3-

<PAGE>

made policy is prior to the date hereof or the date of the making of the first
Loan hereunder, whichever is earlier; that the then remaining aggregate amount
of Borrower's coverage is and will be sufficient to meet the minimum amount of
coverage required hereunder, and that the policy will either remain in force, be
renewed, or a satisfactory discovery period will be purchased to cover any
claims which might arise hereunder in the future. Borrower's obligation to keep
the Equipment insured as provided herein shall continue until the Obligations
are paid in full.

                  (b)      Care, Transfer and Use of Equipment. Borrower, at its
own expense, shall maintain the Equipment in good operating condition and repair
and in compliance with all applicable laws and regulations, and shall protect
the Equipment from deterioration except for reasonable wear and tear resulting
only from proper use thereof. The disrepair or inoperability of the Equipment
regardless of the cause thereof shall not relieve Borrower of its Obligations.
WITHOUT LENDER'S PRIOR WRITTEN CONSENT, BORROWER MAY NOT SELL, CONVEY, TRANSFER,
ASSIGN, SUBLEASE, ENCUMBER ANY ITEMS OF EQUIPMENT OTHER THAN IN THE ORDINARY
COURSE OF ITS BUSINESS, AND ANY SUCH PURPORTED TRANSACTION SHALL BE NULL AND
VOID AND OF NO FORCE OR EFFECT. Borrower shall at its expense at all times keep
the Equipment free from any and all liens, encumbrances, attachments, levies,
executions, burdens, charges or legal process of any and every type whatsoever,
other than Permitted Liens. Lender shall have the right during normal hours upon
reasonable notice to Borrower, subject to applicable laws and regulations, to
enter Borrower's premises in order to inspect or observe the Equipment, or to
otherwise protect Lender's security interest therein.

                  (c)      Equipment Loss. Borrower shall promptly notify Lender
in writing of any Equipment Loss in excess of $10,000.00. In the event of any
such Equipment Loss, Borrower shall either, (a) promptly place, at Borrower's
expense, the Equipment in good repair, condition and working order, or (b)
promptly replace, at Borrower's expense, the Equipment with like equipment of
the same or a later model as the Equipment, and in good repair, condition and
working order. In the event Borrower is required to repair or replace any such
item of Equipment pursuant to this Section, any insurance proceeds received by
Borrower for such Equipment may be applied by Borrower for costs and expenses of
repairing or replacing the Equipment.

                  (d)      Costs of Compliance. Borrower shall promptly pay all
costs, expenses and obligations of every kind and nature incurred in connection
with the use or operation of the Equipment which may arise or become due during
the term of this Agreement. In case of failure by Borrower to comply with any
provision of this Agreement, Lender shall have the right, but not the
obligation, to effect such compliance on behalf of Borrower. In such event, all
costs and expenses incurred by Lender in effecting such compliance shall be
immediately due and payable by Borrower to Lender as additional Obligations
hereunder.

                  (e)      Reports. So long as this Agreement is in effect,
Borrower shall provide Lender with the following: (a) annual and quarterly
financial statements of Parent, prepared in accordance with generally accepted
accounting principles, and (b) prompt written notice of any material adverse
change in Borrower's financial condition, business or operations. In addition,
Borrower shall provide Lender with not less than 30 days prior written notice of
any proposed change in Borrower's financial structure or ownership (e.g.,
merger, consolidation, sale, lease or other disposition of assets not in the
ordinary course).

                  (f)      Obligations; No Set-off. Borrower agrees that its
obligations under this Agreement, including without limitation, the obligation
to repay the Loans, are irrevocable and absolute, shall not abate for any reason
whatsoever (including any claims against Lender). In the event of any alleged
claim (including a claim which would otherwise be in the nature of a set-off)
against Lender, Borrower shall fully perform and pay its obligations hereunder
without set-off or defense of any kind, and its only recourse against Lender
shall be by a separate action.

         6.       Events of Default. Any one or more of the following shall
constitute an Event of Default under this Agreement:

                  (a)      Borrower shall fail to pay any principal of or
interest on any Loans within five days after the date due;

                                      -4-

<PAGE>

                  (b)      Borrower, without the prior consent of Lender,
attempts to or does sell, transfer, encumber, part with possession of, or sublet
any item of the Equipment other than in the ordinary course of its business; or

                  (c)      Borrower shall suffer or have suffered, in the
reasonable judgment of Lender, any event the result of which has caused Lender
reasonably to deem itself to be insecure including, but not limited to, any of
the following: (i) a material adverse change in its financial condition or
business prospects; (ii) a material change in structure (e.g., merger,
consolidation, sale, lease or other disposition of assets not in the ordinary
course); (iii) a material change in ownership (other than a change of ownership
arising out of any distributions of Borrower stock by Saigene Corporation to any
of its shareholders, employees or creditors); (iv) any of the statements or
other documents or information submitted at any time heretofore or hereafter by
Borrower to Lender has misstated or shall misstate or has failed or shall fail
to state a material fact necessary to make such statements made to Lender not
misleading at the time made; or

                  (d)      Borrower shall breach or shall have breached, in any
material respect, any representation or warranty made or given by Borrower in
this Agreement or in any other document furnished to Lender in connection
herewith, or any such representation or warranty shall be untrue or, by reason
of failure to state a material fact necessary to make such statements made to
Lender not misleading at the time made, shall be misleading; or

                  (e)      Borrower shall fail to perform or observe any other
material covenant, condition or agreement to be performed or observed by it
hereunder, and such failure or breach shall continue unremedied for a period of
ten days after the earlier of (i) the date on which Borrower obtains, or should
have obtained knowledge of such failure or breach, or (ii) the date on which
notice thereof shall be given by Lender to Borrower; or

                  (f)      Borrower shall become insolvent or bankrupt or make
an assignment for the benefit of creditors or consent to the appointment of a
trustee or receiver, or a trustee or receiver shall be appointed for a
substantial part of its property without its consent, or bankruptcy or
reorganization or insolvency proceeding shall be instituted by or against
Borrower and not discharged within 60 days; or

                  (g)      Borrower conveys, sells, transfers, subleases or
assigns substantially all of Borrower's assets or ceases doing business as a
going concern, ceases to be in good standing or files a statement of intent to
dissolve, or abandons any or all of the Equipment; or

                  (h)      Borrower shall be in material breach of or default
under any other agreement at any time executed with Lender, or with any other
lender to Borrower.

         7.       Remedies.

                  (a)      Remedies. Upon the occurrence and during the
continuance of any Event of Default, Lender, at its option, may do any one or
more of the following, without notice except for such notices as are required by
law: (i) accelerate and declare the Obligations to be immediately due and
payable, notwithstanding any deferred or installment payments allowed by any
instrument evidencing or relating to any Obligation; (ii) take possession of any
or all of the Collateral wherever it may be found, and for that purpose Borrower
hereby authorizes Lender to enter Borrower's premises without interference to
search for, take possession of, keep, store, or remove any of the Collateral,
and remain on the premises or cause a custodian to remain on the premises in
exclusive control thereof, without charge by Borrower for so long as Lender
reasonably deems it necessary in order to complete the enforcement of its rights
under this Agreement or any other agreement; (iii) require Borrower to assemble
any or all of the Collateral and make it available to Lender at places
designated by Lender which are reasonably convenient to Lender and Borrower, and
to remove the Collateral to such locations as Lender may reasonably deem
advisable; (iv) exercise any other right or remedy which may be available to it
under the Article 9 of the Uniform Commercial Code as then in effect in the
State of Utah. Lender reserves the right, in its sole and absolute discretion,
to release or sell any or all of the Collateral at a public auction or in a
private sale, at such time, on such terms and with such notice as Lender shall
in its sole and absolute discretion deem reasonable. All reasonable attorneys'
fees, expenses, costs, liabilities and obligations incurred by Lender with
respect to the foregoing shall be added to and become part of the Obligations.

                                       -5-

<PAGE>

                  (b)      Application of Proceeds. All proceeds realized as the
result of any sale or other disposition of the Collateral shall be applied by
Lender first to the reasonable costs, expenses, liabilities, obligations and
attorneys' fees incurred by Lender in the exercise of its rights under this
Agreement, second to the interest due upon any of the Obligations, and third to
the principal of the Obligations, in such order as Lender shall determine in its
sole discretion. Any surplus shall be paid to Borrower or other persons legally
entitled thereto; Borrower shall remain liable to Lender for any deficiency.

                  (c)      Remedies Cumulative. In addition to the rights and
remedies set forth in this Agreement, Lender shall have all the other rights and
remedies accorded a secured party under Article 9 of the Utah Uniform Commercial
Code and under all other applicable laws, and all of such rights and remedies
are cumulative and none is exclusive. Exercise or partial exercise by Lender of
one or more of its rights or remedies shall not be deemed an election, nor bar
Lender from subsequent exercise or partial exercise of any other rights or
remedies. The failure or delay of Lender to exercise any rights or remedies
shall not operate as a waiver thereof, but all rights and remedies shall
continue in full force and effect until all of the Obligations have been fully
paid.

                  (d)      Limited Power of Attorney. After the occurrence and
during the continuance of an Event of Default, Borrower irrevocably appoints
Lender (and any of Lender's designated employees or agents) as Borrower's true
and lawful attorney in fact to (i) make, settle and adjust all claims under and
decisions with respect to Borrower's policies of insurance, (ii) settle and
adjust disputes and claims respecting the Collateral; (iii) execute and deliver
all notices, instruments and agreements in connection with the perfection of the
security interest granted in this Agreement, (iv) sell, lease or otherwise
dispose of all or any part of the Collateral, and (v) take any other action or
sign any other documents required to be taken or signed by Borrower, or
reasonably necessary to enforce Lender's rights or remedies or otherwise carry
out the purposes of this Agreement. The appointment of Lender as Borrower's
attorney in fact, and each of Lender's rights and powers, being coupled with an
interest, are irrevocable until all Obligations owing to Lender have been paid
in full.

         8.       Indemnification. Borrower will indemnify and hold harmless
Lender and its officers, employees and agents from and against any and all
liability, loss, costs, damage, penalties, suits, judgments, demands, claims,
expenses and disbursements (including without limitation, reasonable attorneys'
fees) incurred by Lender arising out of, on account of, or in connection with
this Agreement or the Loans.

         9.       Waivers. The failure of Lender at any time or times to require
Borrower to strictly comply with any of the provisions of this Agreement or any
other present or future agreement between Borrower and Lender shall not waive or
diminish any right of Lender later to demand and receive strict compliance
therewith. Any waiver of any default shall not waive or affect any other
default, whether prior or subsequent, and whether or not similar. None of the
provisions of this Agreement or any other agreement shall be deemed to have been
waived except by a specific written waiver signed by an authorized officer of
Lender and delivered to Borrower. Borrower waives demand, protest, notice of
protest and notice of default or dishonor, notice of payment and nonpayment,
release, compromise, settlement, and notice of any action taken by Lender,
unless expressly required by this Agreement.

         10.      Assignment by Lender. LENDER MAY (WITH OR WITHOUT NOTICE TO
BORROWER) SELL, TRANSFER, ASSIGN OR GRANT A SECURITY INTEREST IN ALL OR ANY PART
OF ITS INTEREST IN THE LOANS AND ITS RIGHTS AND OBLIGATIONS UNDER THIS
AGREEMENT. In such an event, Borrower shall, upon receipt of notice from Lender,
acknowledge any such sale, transfer, assignment or grant of a security interest
and shall pay its obligations hereunder or amounts equal thereto to the
respective transferee, assignee or secured party in the manner specified in any
instructions received from Lender. Borrower shall have no liability for failure
to make payments to any such transferee, assignee or secured party until and
unless it has received written notice and instruction from Lender.
Notwithstanding any such sale, transfer, assignment or grant of a security
interest by Lender and so long as no Event of Default shall have occurred and be
continuing hereunder, neither Lender nor any transferee, assignee or secured
party of Lender shall interfere with Borrower's right of use or quiet enjoyment
of the Equipment. In the event of such sale, transfer, assignment or grant of a
security interest in all or any part of the Loans or this Agreement, Borrower
agrees to execute such documents as may be reasonably necessary to evidence,
secure and complete such sale, transfer, assignment or grant of a security
interest and to perfect the transferee's, assignee's or secured party's interest
therein; provided, however, that the rights of any transferee, assignee or
secured party shall be subject to any defense, set-off or counterclaim that
Borrower may have

                                      -6-

<PAGE>

against Lender or any other party. Borrower acknowledges that any assignment or
transfer by Lender shall not materially change Borrower's duties or obligations
under this Agreement nor materially increase the burdens and risks imposed on
Borrower.

         11.      Warrants.

                  (a)      Stock Purchase Warrants. Effective on each date that
the Lender funds a Loan pursuant to Section 2, Pacific Biometrics, Inc., a
Delaware corporation ("Parent"), shall issue and deliver to Lender stock
purchase warrants (collectively, the "Warrants") to purchase shares of Parent
common stock, on the basis of 5,000 shares for each $50,000 in principal amount
of Loans funded by Lender on such date, up to a maximum aggregate number of
25,000 shares (collectively, the "Shares") for all Loans. The exercise price for
each Warrant shall be equal to the fair market value of the common stock as of
the respective date of grant as determined by Parent's board of directors in its
sole discretion. The expiration date for the Warrants shall be ten years from
the respective date of grant. The Warrants shall be subject to proportionate
adjustment in the event of any stock split, stock dividend or similar
recapitalization of Parent capital stock, and shall provide for piggyback
registration rights in connection with a registered public offering of Parent
common stock under the Securities Act (other than a registration statement
relating solely to the sale of securities to participants in a employee benefit
plan or a transaction covered by Rule 145 under the Securities Act), to the
extent permitted under any existing registration rights agreements with such
shareholders and subject to customary underwriter cutbacks, if any. The Warrants
shall be in form and substance acceptable to Parent.

                  (b)      Securities Laws Representations by Lender. In
connection with the grant of Warrants and issuance of Shares upon exercise of
the Warrants, Lender makes the following representations and warranties to
Borrower and Parent:

                  1.       Lender acknowledges that neither the Warrants nor the
                           Shares (collectively, the "Securities") are being
                           registered under the Securities Act of 1933, as
                           amended (the "Securities Act"), or applicable state
                           securities laws, but are being issued pursuant to
                           exemptions from such laws. Lender acknowledges that
                           certificates for the Securities will bear a legend to
                           the effect that the Securities are "restricted
                           securities," transfer of the Securities is restricted
                           pursuant to the Securities Act and applicable state
                           securities laws, and stop-transfer instructions will
                           be placed with the transfer agent for the Securities.
                           Lender understands that there will be securities laws
                           restrictions on its ability to sell, pledge or
                           transfer the Securities, and there are no assurances
                           of a market for the Securities at such time Lender
                           wants to sell them.

                  2.       Lender is acquiring the Securities solely for its own
                           account, for investment purposes only, and not with a
                           view towards their resale or distribution. Lender has
                           no present intention of selling, granting any
                           participation in or otherwise distributing any of the
                           Securities in a manner contrary to the Securities Act
                           or any applicable state securities law.

                  3.       Lender is a sophisticated investor, has sufficient
                           knowledge and experience in financial and business
                           matters that it is capable of evaluating the merits
                           and risks of the prospective investment in the
                           Securities. Lender's principal place of business is
                           in the State of Utah.

                  4.       Lender has been solely responsible for its due
                           diligence investigation of Parent and Borrower and
                           its business, operations, financial condition,
                           assets, liabilities and other relevant matters.
                           Lender has reviewed Parent's filings with the U.S.
                           Securities and Exchange Commission, including the
                           risk factors contained therein. Except as expressly
                           set forth in this Agreement, neither Parent nor
                           Borrower is making any representations or warranties
                           to Lender.

         12.      Costs. Borrower shall reimburse Lender for all reasonable
costs ("Costs") related to this transaction including due diligence costs, legal
costs, costs and fees relating to any filings hereunder (including, but

                                      -7-

<PAGE>

not limited to, filing fees, searches, document preparation, and documentary
stamps) and on-site document preparation costs (if such service is requested by
Borrower) reasonably incurred by Lender; provided that reimbursement for legal
costs shall not exceed $1,000.00. Lender shall provide an itemized statement of
Costs to Borrower, if so requested by Borrower.

         13.      Amendments. This Agreement and the Exhibits and Schedules
hereto contain the entire agreement between the parties with respect to the
transactions contemplated hereby and there is no agreement or understanding,
oral or written, which is not set forth herein. This Agreement may not be
altered, modified, terminated or discharged except by a writing signed by the
party against whom such alteration, modification, termination or discharge is
sought.

         14.      Law. This Agreement shall be binding only when accepted by
 Lender at its principle place of business in Utah and shall in all respects be
governed and construed, and the rights and the liabilities of the parties hereto
determined, except for local filing requirements, in accordance with the laws of
the State of Utah. BORROWER SUBMITS TO THE JURISDICTION OF THE FEDERAL DISTRICT
COURTS OF COMPETENT JURISDICTION OR ANY STATE COURT WITHIN THE STATE OF UTAH AND
WAIVES ANY RIGHT TO ASSERT THAT ANY ACTION INSTITUTED BY LENDER IN ANY SUCH
COURT IS IN THE IMPROPER VENUE OR SHOULD BE TRANSFERRED TO A MORE CONVENIENT
FORUM.

         15.      Invalidity. In the event that any provision of this Agreement
shall be unenforceable in whole or in part, such provision shall be limited to
the extent necessary to render the same valid, or shall be excised from this
Agreement, as circumstances may require, and this Agreement shall be construed
as if said provision had been incorporated herein as so limited, or as if said
provision had not been included herein, as the case may be without invalidating
any of the remaining provisions hereof.

         16.      Confidentiality. In handling any confidential or non-public
information or Borrower or any of its customers that may be provided to Lender
in connection with this Agreement and the transactions hereunder, Lender shall
exercise the same degree of care that it exercises with respect to its own
proprietary information of the same types to maintain the confidentiality of the
same, except that disclosure of such information may be made (a) to subsidiaries
or affiliates of Lender in connection with their present or prospective business
relations with Borrower, (b) to prospective transferees or purchasers of any
interest in the Obligations, provided that they have entered into a comparable
confidentiality agreement with respect thereto, (c) as required by law,
regulations, rule or order, subpoena, judicial order or similar order (provided
Lender first provides Borrower with prompt written notice of any such order
timely enough so that Borrower may seek to oppose such disclosure or seek a
protective order or other appropriate remedy), and (d) as may be required in
connection with the examination, audit or similar investigation of Lender.
Confidential information hereunder shall not include information that either:
(i) is in the public domain, or becomes part of the public domain, after
disclosure to Lender through no fault of Lender; or (ii) is disclosed to Lender
by a third party, provided Lender does not have actual knowledge that such third
party is prohibited from disclosing such information. Lender acknowledges and
agrees that it is aware (and that it will take commercially reasonable steps to
inform its partners, principals, officers, employees, and agents who are
required to have access to confidential information of Borrower) of the
restrictions imposed by the U.S. federal securities laws on a person possessing
material non-public information about a public company.

         17.      Miscellaneous. All notices and demands relating hereto shall
be in writing and shall be deemed to have been given (a) upon receipt, when
delivered by hand or by electronic facsimile transmission, or (b) upon actual
delivery by overnight courier, or (c) three days after mailing by regular
first-class mail or certified mail return receipt requested, addressed to each
party at the addresses indicated below their signatures below, or at any other
address designated by notice served in accordance herewith. All obligations of
Borrower and Lender shall survive the termination or expiration of this
Agreement. Borrower shall, upon reasonable request of Lender from time to time,
perform all acts and execute and deliver to Lender all documents which Lender
deems reasonably necessary to implement this Agreement. This Agreement shall be
binding upon the parties and their successors, legal representatives and
assigns. Borrower's successors and assigns shall include, without limitation, a
receiver, debtor-in-possession, or trustee of or for Borrower.

         18.      Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed an original.

                                                                   EXHIBIT 10.19

                                OPTION AGREEMENT

         This Option Agreement (this "Agreement") is made and entered into
effective this 28th day of August 2002, (the "Effective Date"), by and between
Saigene Corporation, a Delaware corporation ("Saigene"), on the one hand, and
Pacific Biometrics, Inc. a Delaware corporation ("Parent"), and Pacific
Biometrics, Inc., a Washington corporation ("Subsidiary"), on the other hand.

                                   RECITALS:

         WHEREAS, Saigene owns certain molecular technology and has entered into
an Asset Purchase Agreement, dated as of June 27, 2002, by and among Saigene,
Parent and Subsidiary (the "Asset Purchase Agreement," to which this Agreement
is attached as Exhibit E), whereby Saigene is selling certain assets to
Subsidiary; and

         WHEREAS, as part of the consideration for the Asset Purchase Agreement,
Saigene is granting Subsidiary an option to purchase certain of Saigene's other
technology and related physical assets on the terms and conditions stated in
this Agreement.

         NOW, THEREFORE, in consideration of the mutual covenants set forth
herein, and other good and valuable consideration, the receipt and adequacy of
which are hereby acknowledged, the parties agree as follows:

                                   AGREEMENT:

1.0 Option to Purchase.

         1.1 Grant of Option. Subject to the terms and conditions of this
Agreement, Saigene hereby grants Subsidiary an option (the "Option") to purchase
the technology and assets and assume the liabilities listed in Schedule 1.1. The
technology and assets that are the subject of the Option are collectively
referred to as the "Assets." Saigene represents and warrants that at the time of
the Closing (as hereinafter defined) (i) Saigene will have good and valid title
to, or a valid and binding leasehold interest or license in, the Assets free and
clear of any encumbrance, lien, claim, charge, security interest, mortgage,
pledge, easement, conditional sale or other title retention agreement, covenant
or other similar restrictions or third party rights affecting the Assets, (ii)
the Assets constitute all of the assets, interests and rights necessary to
exploit the technology and intellectual property transferred hereunder, and
(iii) Saigene has, and as of the Closing, will have, complied with all
obligations under all leases, licenses, covenants and agreements constituting or
relating to any of the Assets or assumed liabilities, and all such leases,
licenses, covenants and agreements will be in full force and effect and Saigene
is and will be unaware of any defaults or breaches thereunder or circumstances
that may give rise to any defaults or breaches thereunder.

         1.2 Term of Option. The Option granted by Saigene to Subsidiary in
Section 1.1 will commence on the Effective Date and will terminate at 4:00 pm
(local time in Seattle, Washington) on the first anniversary of the Effective
Date (the "Option Period"), after which time it will be of no further force or
effect; provided, however, that if Saigene does not remove all encumbrances on
the Assets (including, without limitation, those encumbrances set forth on
Schedule 1.2 attached hereto) by October 31, 2002, then the Option Period shall
be extended by one day for each day in which said encumbrances remain on the
Assets beyond October 31, 2002. At any time during the Option Period, PBI shall
have the right, but shall not be obligated, to exercise the Option and assume
liabilities in addition to those set forth on Schedule 1.1 in the event the
encumbrances (including those set forth on Schedule 1.2) have not been removed
at the time of exercise of the Option.

         1.3 Consideration for Option. The Purchase Price in the Asset Purchase
Agreement is acknowledged to be adequate consideration paid by Parent and
Subsidiary for the Option granted under this Agreement.

         1.4 Exercise of Option. In order to exercise the Option, Subsidiary
must deliver written notice to Saigene during the Option Period stating
Subsidiary's exercise (without condition or qualification) of the Option (the
"Option Notice"). In order to be timely, the Option Notice must be received by
Saigene before the expiration of the

                                      -1-

<PAGE>

Option Period. The Option Notice must state Subsidiary's election to pay the
Option Price (as defined in Section 1.5) in cash or PBI Stock (as defined in
Section 1.5).

         1.5 Option Price. The purchase price (the "Option Price") for the
Assets is, at Subsidiary's election, either (a) Five Million One Hundred Forty
Seven Thousand One Hundred Eighteen Dollars ($5,147,118.00), or (b) Five Million
One Hundred Forty Seven Thousand One Hundred Eighteen (5,147,118) shares of
Parent's common stock ("PBI Stock"). The Option Price will also include the
assumption of all liabilities relating specifically to the Assets as set forth
on Schedule 1.1, which will be assumed pursuant to an assumption agreement
substantially in the form of Exhibit 1. The Option Price will be payable in full
upon the Closing of the purchase of the Assets as described in this Agreement.

         1.6 Failure to Exercise Option. If Subsidiary does not properly and
timely exercise the Option in accordance with the terms of this Agreement, then
after the Option Period ends, Subsidiary will have no further rights under this
Agreement including, without limitation, the right to purchase the Assets.

         1.7 Purchase Contract. If Subsidiary timely and properly exercises the
Option, then Saigene, Subsidiary, and Parent will immediately begin negotiating
in good faith the terms and conditions (in addition to those contained in this
Agreement which the parties hereby agree to) of an agreement (the "Purchase
Contract") whereby Subsidiary will purchase all of the Assets from Saigene for
the Option Price, payable in full at the Closing (as hereinafter defined);
provided, however, that irrespective of the parties entering into a definitive
Purchase Contract, Saigene shall be obligated to sell the Assets to Subsidiary
for the Option Price. The term "Closing" will mean the date, as specified in the
Purchase Contract, on which Saigene transfers the Assets to Subsidiary in
exchange for the payment in full of the Option Price (in cash or PBI Stock,
evidenced by stock certificate(s) issued by Parent). Upon the Closing, Saigene
will deliver a Bill of Sale substantially in the form of Exhibit 2.

2.0 Terms of Purchase Contract. The parties acknowledge that the terms of the
Purchase Contract set forth in this Agreement (e.g., purchase price, etc.) are
agreed upon terms that will be included in the Purchase Contract. The Purchase
Contract will also contain typical representations and warranties of the parties
concerning the sale of the Assets; however, Parent and Subsidiary acknowledge
that because they are simultaneously entering into the Asset Purchase Agreement,
which contains full representations and warranties from Saigene about its
operations and assets, and Parent and Subsidiary will have the ability to
conduct due diligence during the Option Period, the parties will negotiate in
good faith regarding the representations and warranties that Saigene will make
in the Purchase Contract concerning the Assets; provided, however, that such
representations and warranties should not be materially different from those
contained in the Asset Purchase Agreement. With regard to the Option Price, any
PBI Stock issued to Saigene as part of the Option Price must be fully-paid,
non-assessable, and free and clear of all liens and encumbrances (except those
imposed by federal and state securities laws).

3.0 General Provisions.

         3.1 Integration; Modification; Waiver. This Agreement, including all
exhibits and schedules attached hereto which are incorporated herein, and the
Asset Purchase Agreement constitutes and contains the entire agreement and
understanding concerning the subject matter between the parties, sets forth all
inducements made by any party to any other party with respect to any of the
subject matter, and supersedes and replaces all prior and contemporaneous
negotiations, proposed agreements or agreements, whether written or oral. Each
of the parties acknowledges to each of the other parties that no other party nor
any agent or attorney of any other party has made any promise, representation or
warranty whatsoever, express or implied, written or oral, not contained herein
concerning the subject matter hereof to induce it to execute this Agreement, and
each of the parties acknowledges that it has not executed this Agreement in
reliance on any promise, representation or warranty not contained herein. No
supplement, modification, or amendment of this Agreement will be binding unless
executed in writing by all the parties. No action or failure to act will
constitute a waiver of any right or duty under this Agreement, nor will any
action or failure to act constitute an approval of, or acquiescence in, any
breach. No waiver of any of the provisions of this Agreement will be deemed, or
will constitute, a waiver of any other provision, whether or not similar, nor
will any waiver constitute a continuing waiver. No waiver will be binding unless
executed in writing by the party making the waiver.

                                      -2-

<PAGE>

         3.2 No Third Party Beneficiaries. Nothing in this Agreement, express or
implied, is intended to or shall (a) confer on any person other than the parties
hereto and their respective successors or assigns any rights (including
third-party beneficiary rights), remedies, obligations or liabilities under or
by reason of this Agreement, or (b) constitute the parties hereto as partners or
as participants in a joint venture. This Agreement will not provide third
parties with any remedy, claim, liability, reimbursement, cause of action or
other right in excess of those existing without reference to the terms of this
Agreement. No third party will have any right, independent of any right that
exists irrespective of this Agreement, under or granted by this Agreement, to
bring any suit at law or equity for any matter governed by or subject to the
provisions of this Agreement.

         3.3 Assignment; Binding Effect; Severability. This Agreement may not be
assigned by any party hereto without the other party's written consent;
provided, that after the Closing Date a party may transfer its rights and
obligations hereunder in connection with a merger or sale of all or
substantially all of its assets. This Agreement shall be binding upon and inure
to the benefit of and be enforceable by the successors, legal representatives
and permitted assigns of each party hereto. The provisions of this Agreement are
severable, and in the event that any one or more provisions are deemed illegal
or unenforceable the remaining provisions shall remain in full force and effect
unless the deletion of such provision shall cause this Agreement to become
materially adverse to either party, in which event the parties shall use
reasonable commercial efforts to arrive at an accommodation that best preserves
for the parties the benefits and obligations of the offending provision.

         3.4 Time of the Essence. All times stated in this Agreement are of the
essence.

         3.5 Notices. All notices and other communications hereunder shall be in
writing and shall be deemed to have been duly given upon receipt if (1) mailed
by certified or registered mail, return receipt requested, (2) sent by Federal
Express or other express carrier, fee prepaid, (3) sent via facsimile with
receipt confirmed, or (4) delivered personally, addressed as follows or to such
other address or addresses of which the respective party shall have notified the
other.

behalf of the respective parties, and represent that they are authorized to
enter into and execute this Agreement on behalf of such parties.

         3.8 Further Assurances. The parties agree to execute all instruments
and documents of further assurance and will do any and all such acts as may be
reasonably required to carry out their obligations and to consummate the
transactions contemplated herein.

         3.9 Governing Law; Jurisdiction; Venue. This Agreement will be
construed, interpreted, and enforced in accordance with, and governed by, the
laws of the State of Delaware without regard to conflicts of laws provisions
thereof.

         3.10 Interpretation; Gender. In the event an ambiguity or question of
intent or interpretation arises, this Agreement will be construed as if drafted
jointly by the parties and no presumption or burden of proof will arise favoring
or disfavoring any party by virtue of the authorship of any of the provisions of
this Agreement. Whenever in this Agreement the context may so require, the
masculine gender will be deemed to refer to and include the feminine and neuter,
and the singular will refer to and include the plural, and vice versa.

         3.11 Attorneys' Fees. If any party brings an action, arbitration or
other proceeding arising out of or relating to this Agreement (whether founded

Party (as hereinafter defined) will be entitled to recover its reasonable
attorneys' fees and other costs incurred in the arbitration, action or
proceeding (including all appeals and re-trials), in addition to any other
relief to which the Prevailing Party may be entitled. The term "Prevailing
Party" will include, without limitation, a party who substantially obtains or
defeats the relief sought, as the case may be, whether by compromise,
settlement, judgment, or the abandonment by the other party of its claim or
defense. The attorneys' fees award will not be computed in accordance with any
court fee schedule, but will be such as to fully reimburse all attorneys' fees
reasonably incurred.

given mature and careful thought to this Agreement and that it has been given
the opportunity to independently review this Agreement with its own independent
legal counsel.

the day and year first above written.
