                                    Lessor may obtain such insurance for the

                                    premiums for such blanket policies as are
                                    allocable to the Premises. It is understood
                                    and agreed that Lessee's obligation under

                                    Lessor for premiums shall not exceed
                                    $20,000.00 annually.

                                    loss or damage is insured against under any
                                    insurance policy carried by Lessor or Lessee
                                    hereunder. Each party shall notify their
                                    respective insurance carriers of this
                                    waiver.

                                    merchandise, and all other personal property
                                    in, upon, or about the Premises and for
                                    injuries to persons in or about the
                                    Premises, from any cause arising at any
                                    time, excepting claims arising from the
                                    Lessor's negligence and willful misconduct
                                    or breach of this Lease and the Lessee will
                                    hold the Lessor exempt and harmless from any
                                    damage or injury to any person, or to the
                                    goods, wares and merchandise and all other
                                    personal property of any person, arising
                                    from the use of the Premises by the Lessee,
                                    or from the failure of the Lessee to keep
                                    the Premises in good condition and repair,
                                    as herein provided.





ADVERTISEMENTS AND SIGNS                     16. Lessee will not place or permit

                                    signs not approved by the city or other
                                    governing authority. The Lessee will not
                                    place, or permit to be placed, upon the
                                    Premises, any signs, advertisements or

                                    so placed on the Premises shall be so placed
                                    upon the understanding and agreement that
                                    Lessee will remove same at the termination
                                    of the tenancy herein created and repair any
                                    damage or injury to the Premises caused
                                    thereby, and if not so removed by Lessee
                                    then Lessor may have same so removed at



                                 
                                    Lessee's expense. (*) SEE ADDENDUM ATTACHED


UTILITIES                                    17. Lessee shall pay for all water,

ATTORNEY'S FEES                              18. In case suit should be brought
                                    for the possession of the Premises, for the
                                    recovery or any sum due hereunder, or
                                    because of the breach of any other covenant
                                    herein, the losing party shall pay to the
                                    prevailing party a reasonable attorney's
                                    fee, which shall be deemed to have accrued
                                    on the commencement of such action and shall
                                    be enforceable, whether or not such action
                                    is prosecuted to judgment.


DEFAULT                                      19. In the event of any breach of
                                    this Lease by the Lessee, or an abandonment
                                    of the Premises by the Lessee, the Lessor
                                    has the option of 1) removing all persons
                                    and property from the Premises and
                                    repossessing the Premises in which case any
                                    of the Lessee's property which the Lessor
                                    removes from the Premises may be stored in a
                                    public warehouse or, elsewhere at the cost
                                    of, and for the account of Lessee, or 2)
                                    allowing the Lessee to remain in full
                                    possession and control of the Premises. If
                                    the Lessor chooses to repossess the
                                    Premises, the Lease will automatically
                                    terminate in accordance with provisions of
                                    the California Civil Code, Section 1951.2.
                                    In the event of such termination of the
                                    Lease, the Lessor may recover from the
                                    Lessee: 1) the worth at the time of award of
                                    the unpaid rent which had been earned at the
                                    time of termination including interest at 7%
                                    per annum; 2) the worth at the time of award
                                    of the amount by which the unpaid rent which
                                    would have been earned after termination
                                    until the time of award exceeds the amount
                                    of such rental loss that the Lessee proves
                                    could have been reasonably avoided including
                                    interest at 7% per annum; 3) the worth at
                                    the time of award of the amount by which the
                                    unpaid rent for the balance of the term
                                    after the time of award exceeds the amount
                                    of such rental loss that the Lessee proves
                                    could be reasonably avoided; and 4) any
                                    other amount necessary to compensate the
                                    Lessor for all the detriment proximately
                                    caused by the Lessee's failure to perform
                                    his obligations under the Lease or which in
                                    the ordinary course of things would be
                                    likely to result therefrom. If the Lessor
                                    chooses not to repossess the Premises, but
                                    allows the Lessee to remain in full
                                    possession and control of the Premises, then
                                    in accordance with provisions of the
                                    California Civil Code, Section 1951.4, the
                                    Lessor may treat the Lease as being in full
                                    force and effect, and may collect from the
                                    Lessee all rents as they become due through
                                    the termination date of the lease as
                                    specified in the lease. For the purposes of
                                    this paragraph, the following do not
                                    constitute a termination of Lessee's




                                 
                                    right to possession:

                                    a) Acts of maintenance or preservation or
                                    efforts to relet the property.

                                    b) The appointment of a receiver on the
                                    initiative of the Lessor to protect his
                                    interest under this Lease. (*)

LATE CHARGES                                 20. Lessee hereby acknowledges that
                                    late payment by Lessee to Lessor of rent and
                                    other sums due hereunder will cause Lessor
                                    to incur costs not contemplated by this
                                    lease, the exact amount of which will be
                                    extremely difficult to ascertain. Such costs
                                    include, but are not limited to, processing
                                    and accounting charges, and late charges
                                    which may be imposed on Lessor by the terms
                                    of any mortgage or trust deed covering the
                                    Premises. Accordingly, if any installment of
                                    rent or any other sum due from Lessee shall
                                    not be received by Lessor or Lessor's
                                    designee within ten (10) days after such
                                    amount shall be due, Lessee shall pay to
                                    Lessor a late charge equal to seven and one
                                    half percent (7.5%) of such overdue amount.
                                    The parties hereby agree that such late
                                    charge represents a fair and reasonable
                                    estimate of the costs Lessor will incur by
                                    reason of late payment by Lessee. Acceptance
                                    of such late charge by Lessor shall in no
                                    event constitute a waiver of Lessee's
                                    default with respect to such overdue amount,
                                    nor prevent Lessor from exercising any of
                                    the other rights and remedies granted
                                    hereunder.


SURRENDER OF LEASE                           21. The voluntary or other
                                    surrender of this Lease by Lessee, or a
                                    mutual cancellation thereof, shall not
                                    work a merger, and shall, at the option
                                    of Lessor, terminate all or any existing
                                    subleases or subtenancies, or may, at the
                                    option of Lessor, operate as an assignment
                                    to him of any or all such subleases or
                                    subtenancies.


TAXES                                        22. The Lessee shall be liable for
                                    all taxes levied against personal property
                                    and trade or business fixtures. The Lessee
                                    also agrees to pay, as additional rental,
                                    during the term of this Lease and any
                                    extensions thereof, all real estate taxes
                                    plus the yearly installments of any special
                                    assessments which are of record or which may
                                    become of record during the term of this
                                    lease. If said taxes and assessments are
                                    assessed against the entire building and
                                    building site, and this Lease does not cover
                                    the entire building or building site, the
                                    taxes and assessment installments allocated
                                    to the Premises shall be prorated on a
                                    square footage or other equitable basis, as
                                    calculated by the Lessor. It is understood
                                    and agreed that the Lessee's obligation
                                    under his paragraph will be pro-rated to
                                    reflect the commencement and termination
                                    dates of this Lease. Real estate taxes shall
                                    not include taxes assessed on the net income
                                    of Lessor or any gift, franchise or
                                    inheritance taxes.

                                    mail, postage prepaid, and addressed to
                                    Lessee at the said Premises, whether or not
                                    Lessee has departed from, abandoned or
                                    vacated the Premises.


ENTRY BY LESSOR                              24. Lessee shall permit Lessor and
                                    his agents to enter into and upon the
                                    Premises at all reasonable times for the

                                    purpose of maintaining the building in which
                                    the Premises are situated, or for the

                                    any rebate of rent and without any liability
                                    to Lessee for any loss of occupation or
                                    quiet enjoyment of the Premises thereby
                                    occasioned; and shall permit Lessor and his
                                    agents, at any time within ninety days prior
                                    to the expiration of this Lease, to place
                                    upon the Premises any usual or ordinary "For
                                    Sale" or "To Lease" signs and exhibit the
                                    Premises to prospective tenants at

DESTRUCTION OF PREMISES                      25. In the event of a partial
                                    destruction of the Premises during the said
                                    term from any cause, Lessor shall forthwith
                                    repair the same, provided such repairs can
                                    be made within one hundred twenty (120) days
                                    under the laws and regulations of State,
                                    Federal, County or Municipal authorities,
                                    but such partial destruction shall in no way
                                    annul or void this Lease, except that Lessee
                                    shall be entitled to a proportionate
                                    reduction of rent while such repairs are
                                    being made, such proportionate reduction to
                                    be based upon the extent to which the making
                                    of such repairs shall interfere with the
                                    business carried on by Lessee in the
                                    Premises. If such repairs cannot be made in
                                    one hundred twenty (120) days, Lessor may,
                                    at his option, make same within a reasonable
                                    time, this Lease continuing in full force
                                    and effect and the rent to be
                                    proportionately reduced as aforesaid in this
                                    paragraph provided. In the event that Lessor
                                    does not so elect to make such repairs which
                                    cannot be made in one hundred twenty (120)
                                    days, or such repairs cannot be made under
                                    such laws and regulations, this Lease may be
                                    terminated at the option of either party. In
                                    respect to any partial destruction which
                                    Lessor is obligated to repair or may elect
                                    to repair under the terms of this paragraph,
                                    the provision of Section 1932, Subdivision
                                    2, and of section 1933, Subdivision 4, of
                                    the Civil Code of the State of California
                                    are waived by Lessee. In the event that the
                                    building in which the Premises may be
                                    situated be destroyed to the extent of not
                                    less than fifty percent (50%) of the
                                    replacement cost thereof, Lessor may elect
                                    to terminate this Lease, whether the
                                    Premises be injured or not. A total
                                    destruction of the building in which the
                                    Premises may be situated shall terminate
                                    this Lease. In the event of any dispute
                                    between Lessor and Lessee relative to the
                                    provisions of this paragraph, they shall
                                    each select an arbitrator, the two
                                    arbitrators so selected shall select a third
                                    arbitrator and the three arbitrators so
                                    selected shall hear and determine the
                                    controversy and their decision thereon shall
                                    be final and binding upon both Lessor and
                                    Lessee, who shall bear the cost of such
                                    arbitration equally between them.


ASSIGNMENT AND SUBLETTING                    26. The Lessee shall not assign,
                                    transfer, or hypothecate the leasehold
                                    estate under this Lease, or any interest
                                    therein, and shall not sublet the Premises,
                                    or any part thereof, or any right or
                                    privilege appurtenant thereto, or suffer any
                                    other person or entity to occupy or use the
                                    Premises, or any portion thereof, without,
                                    in each case, the prior written consent of
                                    the Lessor. Lessor agrees not to
                                    unreasonably withhold consent to sublet or
                                    assign. As a condition for granting its
                                    consent to any subletting the Lessor may
                                    require the Lessee to agree to pay to the
                                    Lessor, as additional rental, 50% of all
                                    rents received by the Lessee from its
                                    Sublessee after deductions for brokerage
                                    commissions which are in excess of the
                                    amount payable



                                 
                                    by the Lessee to the Lessor hereunder. The
                                    Lessee shall, by thirty (30) days written
                                    notice, advise the Lessor of its intent to
                                    sublet the Premises or any portion thereof
                                    for any part of the term hereof. Within
                                    thirty (30) days after receipt of Lessee's
                                    notice, Lessor shall either given approval
                                    or disapproval to Lessee to sublease the
                                    portion of the Premises described in
                                    Lessee's notice. If the Lessor approves a
                                    subletting, the Lessee may sublet
                                    immediately after receipt of the Lessor's
                                    written approval. In the event Lessee is
                                    allowed to assign, transfer or sublet the
                                    whole or any part of the Premises, with the
                                    prior written consent of Lessor, no
                                    assignee, transferee or sublessee shall
                                    assign or transfer this Lease, either in
                                    whole or in part, or sublet the whole or any
                                    part of the Premises, without also having
                                    obtained the prior written consent of the
                                    Lessor. A consent of Lessor to one
                                    assignment, transfer, hypothecation,
                                    subletting, occupation or use by any other
                                    person shall not release Lessee from any of
                                    Lessee's obligations hereunder or be deemed
                                    to be a consent to any subsequent similar or
                                    dissimilar assignment, transfer,
                                    hypothecation, subletting, occupation or use
                                    by any other person. Any such assignment,
                                    transfer, hypothecation, subletting,
                                    occupation or use without such consent shall
                                    be void and shall constitute a breach of
                                    this Lease by Lessee and shall, at the
                                    option of Lessor exercised by written notice
                                    to Lessee, terminate this Lease. The
                                    leasehold estate under this Lease shall not,
                                    nor shall any interest therein, be
                                    assignable for any purpose by operation of
                                    law without the written consent of Lessor.
                                    As a condition to its consent, Lessor may
                                    require Lessee to pay all expense in
                                    connection with the assignment, and Lessor
                                    may require Lessee's assignee or transferee
                                    (or other assignees or transferees) to
                                    assume in writing all of the obligations
                                    under this Lease. (*)

CONDEMNATION                                 27. If any part of the premises
                                    shall be taken for any public or
                                    quasi-public use, under any statute or by
                                    right of eminent domain or private purchase
                                    in lieu thereof, and a part thereof remains
                                    which is susceptible of occupation
                                    hereunder, this Lease shall, as to the part
                                    so taken, terminate as of the date title
                                    shall vest in the condemnor or purchaser,
                                    and the rent payable hereunder shall be
                                    adjusted so that the Lessee shall be
                                    required to pay for the remainder of the
                                    term only such portion of such rent as the
                                    value of the part remaining after such
                                    taking bears to the value of the entire
                                    Premises prior to such taking; but in such
                                    event Lessor shall have the option to
                                    terminate this Lease as of the date when
                                    title to the part so taken vests in the
                                    condemnor or purchaser. If all of the
                                    premises, or such part thereof be taken so
                                    that there does not remain a portion
                                    susceptible for occupation hereunder, this
                                    Lease shall thereupon terminate. If a part
                                    or all of the Premises be taken, all
                                    compensation awarded upon such taking shall

                                    no claim thereto, except that Lessee shall
                                    have the right to receive that portion of
                                    the condemnation proceeds based upon the
                                    value of all personal property that Lessee
                                    shall have the right to remove from the
                                    Premises.

                                    freed and relieved of all covenants and
                                    obligations of the Lessor hereunder,
                                    provided that Lessor transfers the security
                                    deposit to the transferee and the transferee
                                    assumes in writing Lessor's obligations
                                    hereunder, and it shall be deemed and
                                    construed, without further agreement between
                                    the parties and the purchaser at any such
                                    sale, or the Lessee of the building, that
                                    the purchaser or lessee of the building has
                                    assumed and agreed to carry out any and all
                                    covenants and obligations of the Lessor
                                    hereunder. If any security be given by the
                                    Lessee to secure the faithful performance of
                                    all or any of the covenants of this Lease on
                                    the part of the Lessee, the Lessor may
                                    transfer and deliver the security, as such,
                                    to the purchaser at any such sale or the
                                    lessee of the building, and thereupon the
                                    Lessor shall be discharged from any further
                                    liability In reference thereto.



SUBORDINATION                                29. Lessee agrees that this Lease
                                    may, at the option of Lessor, be subject and
                                    subordinate to any mortgage, deed of trust
                                    or other instrument of security which has
                                    been or shall be placed on the land and

                                    act of Lessee. The Lessee shall, at any time
                                    hereinafter, on demand, execute any

                                    that may be required by any mortgagee,
                                    mortgagor, or trustor or beneficiary under
                                    any deed of trust for the purpose of
                                    subjecting and subordinating this Lease to
                                    the lien of any such mortgage, deed of trust
                                    or other instrument of security, and the
                                    failure of the Lessee to execute any such
                                    instruments, releases or documents, shall
                                    constitute a default hereunder. Lessee shall
                                    not be required to execute any documents
                                    subordinating this Lease unless the holder
                                    of any such Lien executes a Non-Disturbance
                                    Agreement in favor of Lessee.

                                    hereunder by Lessor shall not be deemed to
                                    be a waiver of any preceding breach by
                                    Lessee of any term, covenant or condition of

                              ADDITIONAL PARAGRAPHS

These additional paragraphs are hereby made apart of that certain Lease dated
December 6, 1996 by and between Zappettini Investment Co., Lessor, and Iridex
Corporation, Lessee, covering premises at 1212 Terra Bella, Mountain View,
California.

         35. Options to Renew. Lessor grants to Lessee two successive two year
options to renew this Lease. The first two year option shall commence, if at
all, on the termination date of this Lease and will terminate on February 29,
2004. The second option period shall commence, if at all, on March 1, 2004
providing that the first option has been exercised and shall terminate on
February 28, 2006. In no event can the 2nd option to renew be exercised unless
the 1st option to renew has been exercised. The option terms shall be governed
by all the terms and conditions as are contained in the Lease excepting that
there shall be no additional options and also excepting the basic monthly
rental. The basic monthly rent for each of the option terms shall be negotiated
by Lessor and Lessee at the time each option is exercised and shall be based on
98 percent of the then market rent for the Premises based on similar space
within a 1 mile radius of the subject property. In no event however, shall the
monthly rental for the first option term be less than $46,457.50 nor shall the
rental amount for the 2nd option term be less than that amount being paid for
the 1st option term. In order to exercise each option, the Lessee must give the
Lessor written notice a minimum of 90 days and a maximum of 120 days prior to
the termination of the immediately preceding term. At the option of the Lessor,
any of the above options to renew may be declared null and void if the Lessee is
in default under any of the terms or conditions of the Lease when said option is
exercised.

         36. Lessor will indemnify, defend and hold Lessee harmless from and
against all costs of response, corrective action, remedial action, claims,
demands, losses and liabilities arising from any pre-existing environmental
contamination which may have occurred prior to the Lessee taking possession of
the Premises.

Lessee will only be responsible for contamination of the Premises or the soils
or ground water thereon or thereunder in violation of Hazardous Materials Laws,
that Is caused by Lessee or Lessee's agents, contractors or invitees during the
term as may be extended. All hazardous materials and toxic wastes that Lessee
brings on the Premises shall be stored according to Hazardous Materials Law.

All hazardous materials and toxic wastes that Lessee brings on the site shall be
stored according to all local, state and national government regulations.
Hazardous Materials shall be defined as those substances that are recognized as
posing a risk of injury to health or safety by the Santa Clara Fire Department,
the Santa Clara County Health Department, the Regional Water Quality Control
Board, the State of California or the Federal Government.

For purposes of this Lease, "Hazardous Materials Law" shall mean all local,
state and federal laws, statutes, ordinances, rules, regulations, judgements,
injunctions, stipulations, decrees, orders, permits, approvals, treaties or
protocols now or hereafter enacted, issued or promulgated by any governmental
authority which relate to any Hazardous Material or the use, handling,
transportation,

production, disposal, discharge, release, emission, sale or storage of, or the
exposure of any person to, a Hazardous Material.

Lessor hereby releases Lessee from and waives all claims, costs, losses, damages
and liabilities ("Claims") against Lessee, arising out of or in connection with
any Hazardous Material present at any time on, in, under or about the Premises
except to the extent that any such Claims results from the release, disposal,
emission or discharge of Hazardous Materials on or about the Premises by Lessee
by its agent, contractors or employees. In this regard, Lessor hereby waives the
benefits of California Civil Code Section 1542 which provides as follows: "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 have affected his settlement with debtor."

ADDED TO THE END OF PARAGRAPH 6: *Notwithstanding anything to the contrary in
this Lease, (i) if possession of the Premises has not been delivered to Lessee
for any reason whatsoever on or before March 1, 1997, Lessee shall not be
obligated to pay rent for that period of time after the Rent Commencement Date
equal to the number of days that possession of the Premises is delayed beyond
March 1, 1997, and (ii) if possession of the Premises is not delivered to Lessee
for any reason whatsoever on or before April 30, 1997 then Lessee may terminate

special purpose improvements installed in the Premises by Lessee at Lessee's
cost including, without limitation, supplementary heating, ventilation and air

repair, maintenance or improvement (i) required as a result of a construction
defect in the Premises as of the Commencement Date, and (ii) for which Lessor

insurers). Lessee shall have the benefit of any construction and/or equipment
warranties existing in favor of Lessor that would assist Lessee in discharging

which is reimbursable by Lessee, shall be amortized over the useful life of the
Capital Repair determined in accordance with generally accepted accounting
principles with interest on the unamortized balance at the then prevailing
market rate Lessor would pay if it borrowed funds to replace these units from an
institutional lender. Lessor shall inform Lessee of the monthly amortization
payment required to so amortize such costs, and shall also provide Lessee with
the information upon which such determination is made. Tenant shall pay such
amortized payment for each month during the term of the Lease after such
improvement is completed until the first to occur of (i) the resetting of rent
or the end of the term over which such costs were amortized. Such amortized
amount shall be due at the same time that rent is due.

         3. The cost of any Capital Repair performed by Lessor shall be shared
by Lessee and Lessor as follows. Upon completion of the Capital Repair, Lessor
shall notify Lessee of the total cost incurred by Lessor to complete the work
and shall deliver to Lessee documentary support for such costs and lien waivers
(or lien release bonds) for such work. Lessee shall be responsible for that
portion of the cost incurred by Lessor for the Capital Repair times a fraction,
the numerator of which shall be equal to the lesser of the months in the Lease
term (a) until the resetting of monthly rent for the Premises based upon the
fair market value of the Premises as so repaired or improved, or (b) the useful
life of the capital repairs and the denominator shall be the months on the
useful life of the capital repair.

days after the first day of each month, and (ii) Lessee shall not be in default
or breach of this Lease for failing to perform any covenant of this Lease (other
than a covenant to pay money to Lessor) unless Lessee's failure to perform such
covenant continues for a period of thirty (30) days after Lessee's receipt of
written notice of such failure, or such longer time as may be reasonably
required to cure the default so long as Lessee commences to cure such failure
within thirty (30) day period and diligently prosecutes such cure to completion.

ADDITION TO PARAGRAPH 24:

Lessor shall provide to Lessee twenty-four (24) hours' notice prior to its entry
onto the Premises (except in the event of an emergency) and such entry shall be
subject to Lessee's right to accompany Lessor at all times and Lessee's
reasonable security precautions. Lessor shall ensure that reasonable

reasonable efforts to mitigate any interference with Lessee's business caused by
Lessor's entry and work.

ADDITION TO PARAGRAPH 25:

         Landlord shall have the additional right to terminate the Lease in the
event of a casualty which is not required hereunder to be covered by insurance

participate in assignment and subletting proceeds, sublease the Premises or
assign the Lease to: (i) a corporation controlling, controlled by or under
common control with Lessee; (ii) a successor corporation related to Tenant by

substantially all of the assets of Lessee.

ADDITION TO PARAGRAPH 14:

provisions of paragraph 10 with regard to capital repairs shall apply. The
paragraph 14 shall not apply to any requirement regarding any Hazardous
Material.

Iridex Corporation to make any payments to Zappettini Investment Co. on account

         may require the Lessee to agree to pay to Lessor, as additional rental,
         50% of all rents received by the Lessee from its Sublessee after
         deductions for brokerage commissions which are in excess of the amount
         payable by the Lessee to the Lessor hereunder."

         Please document your waiver of this sentence from the aforementioned
Lease by signing below* and returning a signed original of this letter to our
offices at 340 Pioneer Way, Mountain View CA 94041.
