Company  with  all  ownership  rights  in  the  Intellectual  Property.  If  any

and the  Consultant  shall  execute such  assignments  and other  documents  and
provide  such  assistance  as the  Company  may  reasonably  request in order to
protect the Company's  ownership of the  Intellectual  Property.  The Consultant
hereby appoints the Company as his attorney-in-fact to execute any document that
the U.S. Patent and Trademark  Office,  the U.S.  Copyright Office, or any other
similar  governmental  or  quasi-governmental  entity  in any  state or  foreign
country shall require in order to establish,  protect,  and record the Company's
ownership of all of the rights,  title and interests in and to the  Intellectual
Property.  This  appointment  of the  Company  as the  attorney-in-fact  for the
Consultant to act hereunder is irrevocable.

of this Agreement and shall continue until the later of (i) five (5) years after
the Date of Termination, or (ii) fifty (50) years after the Effective Date.

11.  INDEPENDENT  CONTRACTOR  OBLIGATIONS.  It  is  expressly  agreed  that  the
Consultant is acting as an  independent  contractor in performing  the Services.
The  Company  shall carry no Workers'  Compensation  insurance  or any health or
accident  insurance  to  cover  the  Consultant  or any of  its  Consultants  or
contractors.  The Consultant shall carry all such insurance as shall be required
by law and as it deems appropriate, and shall provide the Company with a copy of
each such  insurance  policy upon the request of the Company.  The Company shall
not pay any contribution to Social Security,  unemployment insurance, federal or
state withholding  taxes, nor provide any other  contributions or benefits which
might  be  expected  to  be  paid  by  an  employer  in  an  employer-Consultant
relationship. The Consultant expressly agrees to report and to pay, on or before
the date due,  any and all  contributions  for  taxes,  unemployment  insurance,
Social  Security,  and other benefits for itself and its  Consultants.  Upon the
request of the Company,  the Consultant shall provide evidence,  satisfactory to
the  Company,  that all such tax and other  payments  required to be made by the
Consultant under this Section have been timely paid when and as due.

12. ARBITRATION.  Any failure to perform, controversy or claim arising out of or
relating to this Agreement or the breach, termination or validity thereof, shall
be determined  exclusively by  arbitration in accordance  with the provisions of
this  Section  and in  accordance  with the  rules of the  American  Arbitration
Association for arbitrating commercial matters. The arbitration shall be held in
Washington,  D.C., the surrounding  metropolitan area of Maryland, or such other
location as the parties shall mutually agree.  The arbitrators  shall base their
award on applicable  Maryland law and judicial  precedent,  and shall  accompany
their award with written  findings of fact and  conclusions of law. The decision
of the  arbitrators  shall be binding on the parties,  except that any party may
appeal the arbitrators'  decision by filing an action to reconsider the decision
of the arbitrators in a court having jurisdiction  hereunder. In any such action
the  arbitrators'  findings  of fact  shall be  conclusive  and  binding on both
parties  and the sole  questions  to be  determined  by

<PAGE>

the court shall be (i) whether or not the arbitrators'  decision was contrary to
Maryland law and judicial  precedent,  and (ii) if the court determines that the
arbitrators' decision was contrary to Maryland law and judicial precedent,  then
how the dispute shall be resolved  based on the  arbitrators'  findings of facts
and  Maryland law and  judicial  precedent.  The decision of the court as to the
resolution  of the dispute  under  Maryland  law and  judicial  precedent  shall
supercede the  arbitrators'  decision.  Judgment upon the award  rendered by the
arbitrators,  as modified  by the court,  if  applicable,  may be entered in any
court having jurisdiction in accordance herewith.

     12.1  SELECTION OF  ARBITRATORS.  One  arbitrator  shall be selected by the
Company and one by the  Consultant,  and the  arbitrators  shall mutually select
another  arbitrator  to serve with them so that there  shall be an odd number of
arbitrators.  Alternatively, the parties may agree to accept a single arbitrator
to be mutually agreed upon by the parties.  Each person serving as an arbitrator
hereunder  shall be a  professional  with  excellent  academic and  professional
credentials  who has had  experience  as an  arbitrator  and at least  ten years
experience  in the field of  resolving  commercial  disputes  in the  Washington
Metropolitan area.

     12.2  DISCOVERY.  Each party shall,  upon the written  request of the other
party,  provide the other with copies of documents relevant to the issues raised
thereby.  Other  discovery may be ordered by the  arbitrators  to the extent the
arbitrators deem additional  discovery  appropriate,  and any dispute  regarding
discovery,  including disputes as to the need therefor or the relevance or scope
thereof,  shall be determined by the arbitrators,  which  determination shall be
conclusive.

     12.3  EXPENSES.  Each  party  shall pay its own  expenses  incurred  in any
arbitration proceeding,  except as may be otherwise provided by the rules of the
American Arbitration Association.

     12.4  CONFIDENTIALITY  OF PROCEEDINGS.  The arbitrators,  expert witnesses,
stenographic  reporters  and any other  third  parties  shall  sign  appropriate
nondisclosure  agreements  in the event  that any  confidential  or  proprietary
information is or may be disclosed in the arbitration proceedings.

                           LEASE TERMINATION AGREEMENT

         This Lease Termination Agreement ("Termination Agreement") is entered
into as of March 22, 2004 (the "Effective Date"), by and between BRITANNIA
POINTE GRAND LIMITED PARTNERSHIP, a Delaware limited partnership ("Landlord"),
and VIROLOGIC, INC., a Delaware corporation ("Tenant"), with reference to the
following facts:

                                    RECITALS

         A. Tenant and Landlord are parties to that certain Lease dated August
27, 1997, as amended by a First Amendment to Lease dated as of December 17, 1997
(as amended, the "Lease"), for those certain premises consisting of
approximately 24,725 square feet located on the first and second floors of
Building G in the Britannia Pointe Grand Business Park at 270 East Grand Avenue,
Suite 52, South San Francisco, California (the "Premises").

         B. Concurrently with the execution of this Termination Agreement,
Landlord is entering into a new lease for the Premises with a third party
unaffiliated with Tenant (the "New Lease"). Landlord has advised Tenant that
Landlord will not sign this Termination Agreement until Landlord has received a
signed New Lease from the tenant thereunder.

         C. In connection with the execution of the New Lease, Landlord and
Tenant wish to effect an early termination of the Lease and to release each
other from all further obligations thereunder, effective as of the Effective
Date, subject to the provisions of this Termination Agreement.

         NOW, THEREFORE, in consideration of the foregoing and of the mutual
agreements set forth below, Landlord and Tenant hereby agree as follows:

                                    AGREEMENT

         1. Termination of Lease. Effective as of the Effective Date, the Lease
is terminated and Landlord and Tenant release the other, their respective
predecessors and successors in interest, and their respective affiliates,
officers, directors, partners, shareholders, agents and employees from all past,
present and future covenants, obligations, claims and causes of action, known or
unknown, arising out of or in connection with the Lease, except to the extent
any such matters (a) relate to or arise out of events, circumstances or time
periods occurring prior to the Effective Date (so that, by way of example but
not limitation, the parties will retain their respective rights and obligations
under the Lease with respect to matters such as environmental incidents or
conditions occurring prior to the Effective Date and claims for personal injury
or property damage occurring prior to the Effective Date) or (b) arise under or
are expressly preserved in this Termination Agreement. Nothing in this
Termination Agreement is intended to affect the status or enforceability of any
stock warrants previously issued by Tenant pursuant to or in connection with the
Lease. Tenant shall surrender physical possession of the Premises to Landlord on
the Effective Date in the condition required under this Termination Agreement,
together with all keys and access codes (if any) relating to the Premises.
<PAGE>
         2. Termination Payment. Tenant shall pay to Landlord in immediately
available funds, by wire transfer to an account designated in writing by
Landlord, the sum of Four Hundred Thousand and No/100 Dollars ($400,000.00) (the
"Termination Payment") in full satisfaction of all obligations of Tenant under
the Lease (except those obligations, if any, arising under or expressly
preserved in this Termination Agreement). The Termination Payment shall be
payable in two equal installments of Two Hundred Thousand and No/100 Dollars
($200,000.00) each, the first of which installments shall be paid no later than
March 31, 2004 and the second of which installments shall be paid no later than
April 9, 2004.

         3. Condition of Premises. Landlord and Tenant have conducted
walkthroughs and inspections of the Premises and have agreed that there are no
repairs or other actions that must be made, taken or paid for by Tenant in
connection with the surrender of the Premises hereunder; provided, however, that
neither the preceding portion of this sentence nor the release in Paragraph 1
above is intended or shall be construed to waive any of Landlord's rights or
Tenant's obligations under the Lease with respect to any environmental
conditions presently existing in or about the Premises that cannot reasonably be
identified by a walkthrough and visual inspection of the Premises, and Landlord
expressly reserves all of its rights with respect to any such conditions. Tenant
acknowledges that as provided in Section 8.2(c) of the Lease, Tenant waives and
releases any and all rights with respect to any personal property, trade
fixtures or other items remaining on the Premises on the Effective Date.

         4. Security Deposit. Landlord presently holds a security deposit from
Tenant, pursuant to the Lease, in the amount of $11,270.55. Landlord shall
return the security deposit to Tenant within five (5) days after Tenant pays the
second (final) installment of the Termination Payment; provided, however, that
if Tenant has timely paid the required first installment of the Termination
Payment and is making timely payment of the required second installment of the
Termination Payment, then Landlord authorizes Tenant to offset the amount of the
security deposit against the second installment and to make the amount of the
second installment net of that offset.

         5. No Assignment. Each party warrants and represents that it has not
made any assignment, sublease (other than subleases by Tenant that have
previously terminated), transfer, conveyance or other disposition of its
interest in the Lease or of any claim, demand, obligation, liability, action or
cause of action arising out of or in connection with the Lease.

         6. Notices. Any notice or other communication given or required to be
given under this Termination Agreement shall be given in accordance with the
notice provisions set forth in Section 17.1 of the Lease, which provisions are
incorporated herein by this reference as if fully set forth, except that the
parties' respective notice addresses are amended to read as follows:

         7. Governing Law. This Termination Agreement shall be governed by and
construed and enforced in accordance with the laws of the State of California,
without giving effect to principles of conflicts of laws.

         8. Counterparts; Facsimile Signatures. This Termination Agreement may
be executed in two or more counterparts, and by separate parties on separate
counterparts, each of which counterparts shall be deemed an original and all of
which counterparts taken together shall constitute one and the same instrument.
The parties contemplate that they may be executing counterparts of this
Agreement transmitted by facsimile, and agree and intend that a signature
delivered by facsimile transmission shall bind the party so signing with the
same effect as though the signature were an original signature.

         9. Broker. Each of Landlord and Tenant respectively represents to the
other that the representing party is not obligated to compensate any broker in
connection with the negotiation or execution of this Termination Agreement.
Landlord and Tenant shall each indemnify and hold the other harmless from and
against any loss, cost, expense or damage arising from any claim for commission
or other compensation made in connection with the negotiation or execution of
this Termination Agreement by any broker claiming by, through or under the
indemnifying party.

         10. Due Authority. Each individual executing this Termination Agreement
on behalf of one of the parties warrants and represents that he or she has the
authority to do so and to bind the legal entity on whose behalf he or she acted.

         11. Waiver of Unknown Claims. Each of Landlord and Tenant respectively,
having been informed of and having read the provisions of California Civil Code
Section 1542, knowingly and intentionally waives any protection afforded to such
party by California Civil Code Section 1542, which provides:

                                     - 3 -
<PAGE>
                  A general release does not extend to claims which the creditor
                  does not know or suspect to exist in his favor at the time of
                  executing the release, which if known by him must have
                  materially affected his settlement with the debtor.

This Termination Agreement is intended to cover all claims or possible claims
arising out of or related to those matters expressly covered by (and not carved
out or reserved from) the releases set forth in this Termination Agreement,
whether such claims or possible claims are known, unknown or hereafter
discovered or ascertained, and the provisions of California Civil Code Section
1542 and any other state and/or Federal counterpart thereto are hereby expressly
waived. Each of Landlord and Tenant respectively expressly acknowledges that it
has been advised by its counsel of the contents and effect of such Section, and
with such knowledge such respective party hereby expressly waives whatever
benefits it may have pursuant to such Section.

         12. Entire Agreement; Amendment. This Termination Agreement contains
the entire agreement of the parties with regard to the subject matter hereof and
there are no other understandings, written or oral, between the parties relating
to the subject matter of this Termination Agreement. No provision of this
Termination Agreement may not be amended or waived except by an agreement in
writing signed by the parties hereto or their respective successors and assigns.

         13. Time of the Essence. Time is of the essence of this Termination
Agreement and of each and every obligation hereunder.

         14. Attorneys' Fees. In the event of any action between the parties
hereto arising out of or in connection with this Termination Agreement, the
prevailing party shall be entitled to recover all reasonable costs, including
(but not limited to) reasonable accountants' fees and attorneys' fees, incurred
by it in connection with such action (including, but not limited to, any
appellate proceedings relating thereto) or in connection with the enforcement of
any judgment rendered in such action. "Prevailing party" within the meaning of
this Section shall include, without limitation, a party who dismisses an action
for recovery hereunder in exchange for payment of the sums allegedly due,
performance of covenants allegedly breached or consideration substantially equal
to the relief sought in the action.
