7.11      REFERENCE PROVISION.

(a)    Other than (i) nonjudicial foreclosure and all matters in connection
therewith regarding security interests in real or personal property; or (ii) the
appointment of a receiver, or the exercise of other provisional remedies (any
and all of which may be initiated pursuant to applicable law), each controversy,
dispute or claim between the parties arising out of or relating to this Credit
Agreement, any security agreement executed by Borrower in favor of Bank or any
note executed by Borrower in favor of Bank  or any other agreement or instrument
issued in favor of Bank by Borrower (collectively in this Section, the
"Agreement") which controversy, dispute or claim is not settled in writing
within thirty (30) days after the "CLAIM DATE" (defined as the date on which a
party subject to this Agreement gives written notice to all other parties that a
controversy, dispute or claim exists), will be settled by a reference proceeding
in California in accordance with the provisions of Section 638 ET SEQ. of the
California Code of Civil Procedure, or their successor section ("CCP"), which
shall constitute the exclusive remedy for the settlement of any controversy,
dispute or claim concerning this Agreement, including whether such controversy,
dispute or claim is subject to the reference proceeding and except as set forth
above, the parties waive their rights to initiate any legal proceedings against
each other in any court or jurisdiction other than the Superior Court in the
County where the Real Property, if any, is located or Los Angeles County if none
(the "COURT").  The referee shall be a retired Judge of the Court selected by
mutual agreement of the parties, and if they cannot so agree within forty-five
(45) days after the Claim Date, the referee shall be promptly selected by the
Presiding Judge of the Court (or his representative).  The referee shall be
appointed to sit as a temporary judge, with all of the powers for a temporary
judge, as authorized by law, and upon selection should take and subscribe to the
oath of office as provided for in Rule 244 of the California Rules of Court (or
any subsequently enacted Rule).  Each party shall have one peremptory challenge
pursuant to CCP Section 170.6.  The referee shall (a) be requested to set the
matter for hearing within sixty (60) days after the date of selection of the
referee and (b) try any and all issues of law or fact and report a statement of
decision upon them, if possible, within ninety (90) days of the Claim Date.  Any
decision rendered by the referee will be final, binding and conclusive and
judgment shall be entered pursuant to CCP Section 644 in any court in the state
of California having jurisdiction.  Any party may apply for a reference
proceeding at any time after thirty (30) days following notice to any other
party of the nature of the controversy, dispute or claim, by filing a petition
for a hearing and/or trial.  All discovery permitted by this Agreement  shall be
completed no later than fifteen (15) days before the first hearing date
established by the referee.  The referee may extend such period in the event of
a party's refusal to provide requested discovery for any reason whatsoever,
including, without limitation, legal objections raised to such discovery or
unavailability of a witness due to absence or illness.  No party shall be
entitled to "priority" in conducting discovery.  Depositions may be taken by
either party upon seven (7) days written notice, and request for production or
inspection of documents shall be responded to within ten (10) days after
service.  All disputes relating to discovery which cannot be resolved by the
parties shall be submitted to the referee whose decision shall be final and
binding upon the parties.  Pending appointment of the referee as provided
herein, the Superior Court is empowered to issue temporary and/or provisional
remedies, as appropriate.

(b)    Except as expressly set forth in this Agreement, the referee shall
determine the manner in which the reference proceeding is conducted including
the time and place of all hearings, the order of presentation of evidence, and
all other questions that arise with respect to the course of the reference
proceeding.  All proceedings and hearings conducted before the referee, except
for trial, shall be conducted without a court reporter except that when any
party so requests, a court reporter will be used at any hearing conducted before
the referee.  The party making such a request shall have the obligation to
arrange for and pay for the court reporter.  The costs of the court reporter at
the trial shall be borne equally by the parties.

(c)    The referee shall be required to determine all issues in accordance with
existing case law and the statutory laws of the state of California.  The rules
of evidence applicable to proceedings at law in the state of California will be
applicable to the reference proceeding.  The referee shall be empowered to enter
equitable as well as legal relief, to provide all temporary and/or provisional
remedies and to enter equitable orders that will be binding upon the parties.
The referee shall issue a single judgment at the close of the reference
proceeding which shall dispose of all of the claims of the parties that are the
subject of the reference.  The parties hereto expressly reserve the right to
contest or appeal from the final judgment or any appealable order or appealable
judgment entered by the referee.  The parties hereto expressly reserve the right
to findings of fact, conclusions of laws, a written statement of decision, and
the right to move for a new trial or a different judgment, which new trial, if
granted, is also to be a reference proceeding under this provision.

(d)    In the event that the enabling legislation which provides for appointment
of a referee is repealed (and no successor statute is enacted), any dispute
between the parties that would otherwise be determined by the reference
procedure herein described will be resolved and determined by arbitration.  The
arbitration will be conducted by a retired judge of the Court, in accordance
with the California Arbitration Act, Section 1280 through Section 1294.2 of the
CCP as amended from time to time.  The limitations with respect to discovery as
set forth hereinabove shall apply to any such arbitration proceeding.

7.12      SURETYSHIP WAIVERS AND CONSENTS.       Each Borrower agrees that it is
jointly and severally, directly, and primarily liable to Bank for payment in
full of all obligations under the Loan Documents ("Obligations") and that such
liability is independent of the duties, obligations and liabilities of the other
Borrower.  The Loan Documents are a primary and original obligation of each
Borrower, are not the creation of a surety relationship, and are an absolute,
unconditional, and continuing promise of payment and performance which shall
remain in full force and effect without respect to future changes in conditions,
including any change of law or any invalidity or irregularity with respect to
the Loan Documents.  Each Borrower acknowledges that the obligations of such
Borrower undertaken herein might be construed to consist, at least in part, of
the guaranty of obligations of persons or entities other than such Borrower
(including any other Borrower party hereto) and, in full recognition of that
fact, each Borrower consents and agrees that the Bank  may, at any time and from
time to time, without notice or demand, whether before or after any actual or
purported termination, repudiation, or revocation of this Agreement by any one
or more Borrowers, and without affecting the enforceability or continuing
effectiveness hereof as to each Borrower: (a) supplement, restate, modify,
amend, increase, decrease, extend, renew, accelerate, or otherwise change the
time for payment or the terms of the Obligations or

any part thereof, including any increase or decrease of the rate(s) of
interest thereon; (b) supplement restate, modify, amend, increase, decrease
or waive, or enter into or give any agreement, approval, or consent with
respect to, the Obligations or any part thereof, or any of the Loan Documents
or any additional security or guaranties, or any condition covenant, default,
remedy, right, representation or term thereof or thereunder; (c) accept new
or additional instruments, documents or agreements in exchange for or
relative to any of the Loan Documents or the Obligations or any part thereof;
(d) accept partial payments on the Obligations; (e) receive and hold
additional security or guaranties for the Obligations or any part hereof; (f)
release, reconvey, terminate, waive, abandon, fail to perfect, subordinate,
exchange, substitute, transfer, or enforce any security or guaranties, and
apply any security and direct the order or manner of sale thereof as the Bank
in its sole and absolute discretion may determine; (g) release any Person
from any personal liability with respect to the Obligations or any part
thereof; (h) settle, release on terms satisfactory to the Bank or by
operation of applicable laws, or otherwise liquidate or enforce any
Obligations and any security therefor or guaranty thereof in any manner,
consent to the transfer of any security and bid and purchase at any sale; or
(i) consent to the merger, change, or any other restructuring or termination
of the corporate or partnership existence of any Borrower or any other
Person, and correspondingly restructure the Obligations, and any such merger,
change, restructuring, or termination shall not affect the liability of any
Borrower or the continuing effectiveness hereof, or the enforceability hereof
with respect to all or any part of the Obligations.

        Upon the occurrence and during the continuance of any Event of Default,
the Bank  may enforce this Agreement independently as to each Borrower and
independently of any other remedy or security the Bank  at any time may have or
hold in connection with the Obligations, and it shall not be necessary for the
Bank to marshal assets in favor of any Borrower or any other Person or to
proceed upon or against or exhaust any security or remedy before proceeding to
enforce this Agreement.  Each Borrower expressly waives any right to require the
Bank to marshal assets in favor of any Borrower or any other Person or to
proceed against any other Borrower or any Collateral provided by any Person, and
agrees that the Bank may proceed against Borrowers or any Collateral in such
order as it shall determine in its sole and absolute discretion.

       The Bank  may file a separate action or actions against any Borrower,
whether action is brought or prosecuted with respect to any security or against
any other person, or whether any other person is joined in any such action or
actions.  Each Borrower agrees that the Bank and any Borrower and any affiliate
of any Borrower may deal with each other in connection with the Obligations or
otherwise, or alter any contracts or agreements now or hereafter existing
between any of them, in any manner whatsoever, all without in any way altering
or affecting the continuing efficacy of this Agreement.

       The Bank's hereunder shall be reinstated and revived, and the
enforceability of this Agreement shall continue, with respect to any amount at
any time paid on account of the Obligations which thereafter shall be required
to be restored or returned by the Bank, all as though such amount had not been
paid.  The rights of the Bank  created or granted herein and the enforceability
of this Agreement  at all times shall remain effective to cover the full amount
of all the Obligations even though the Obligations, including any part thereof
or any other security or guaranty therefor, may be or hereafter

may become invalid or otherwise unenforceable as against any Borrower and
whether or not any other Borrower shall have any personal liability with
respect thereto.

       To the maximum extent permitted by applicable law and to the extent that
a Borrower is deemed a guarantor, each Borrower expressly waives any and all
defenses now or hereafter arising or asserted by reason of (a) any disability or
other defense of any other Borrower with respect to the Obligations, (b) the
unenforceability or invalidity of any security or guaranty for the Obligations
or lack of perfection or continuing perfection or failure of priority of any
security for the Obligations, (c) the cessation for any cause whatsoever of the
liability of any other Borrower (other than by reason of the full payment and
performance of all Obligations), (d) any failure of the to marshal assets in
favor Bank of any Borrower or any other person, (e) any failure of the Bank to
give notice of sale or other disposition of collateral to any Borrower or any
other Person or any defect in any notice that may be given in connection with
any sale or disposition of collateral, (f) any failure of the Bank  to comply
with applicable law in connection with the sale or other disposition of any
collateral or other security for any Obligation, including any failure of the
Bank to conduct a commercially reasonable sale or other disposition of any
collateral or other security for any Obligation, (g) any act or omission of the
Bank or others that directly or indirectly results in or aids the discharge or
release of any Borrower or the Obligations or any security or guaranty therefor
by operation of law or otherwise, (h) any law which provides that the obligation
of a surety or guarantor must neither be larger in amount nor in other respects
more burdensome than that of the principal or which reduces a surety's or
guarantor's obligation in proportion to the principal obligation, (i) any
failure of the Bank to file or enforce a claim in any bankruptcy or other
proceeding with respect to any Person, (j) the election by the Bank of the
application or non-application of Section 1111(b)(2) of the United States
Bankruptcy code, (k) any extension of credit or the grant of any lien under
Section 364 of the United States Bankruptcy code, (1) any use of cash collateral
under Section 363 of the United States Bankruptcy Code, (m) any agreement or
stipulation with respect to the provision of adequate protection in any
bankruptcy proceeding of any Person, (n) the avoidance of any lien in favor of
the Bank for any reason, or (o) any action taken by the Bank that is authorized
by this section or any other provision of any Loan Document.  Until such time as
all of the Obligations have been fully, finally, and indefeasibly paid in full
in cash: (i) each Borrower hereby waives and postpones any right of subrogation
it has or may have as against any other Borrower respect to the Obligations; and
(ii) in addition, each borrower also hereby waives and postpones any right to
proceed or to seek recourse against or with respect to any property or asset of
any other Borrower.  Each borrower expressly waives all setoffs and
counterclaims and all presentments, demands for payment or performance, notices
of nonpayment or nonperformance, protests, notices of protest, notices of
dishonor and all other notices or demands of any kind or nature whatsoever with
respect to the Obligations, and all notices of acceptance of this Agreement or
of the existence, creation or incurring of new or additional Obligations.

          In the event that all or any part of the Obligations at any time are
secured by any one or more deeds of trust or mortgages or other instruments
creating or granting liens on any interests in real property, each Borrower
authorizes the Bank, upon the occurrence of and during the continuance of any
Event of Default, at its sole option, without notice or demand and without
affecting the obligations of any Borrower, the enforceability of this Agreement,
or the validity or enforceability of any Liens of the Bank,

to foreclose any or all of such deeds of trust or mortgages or other
instruments by judicial or nonjudicial sale.

       To the fullest extent permitted by applicable law, to the extent that a
Borrower is deemed a guarantor, each Borrower expressly waives any defenses to
the enforcement of this Agreement or any rights of the Bank created or granted
hereby or to the recovery by the Bank against any Borrower or any other Person
liable therefor of any deficiency after a judicial or nonjudicial foreclosure or
sale, even though such a foreclosure or sale may impair the subrogation rights
of Borrowers and may preclude Borrowers from obtaining reimbursement or
contribution from other Borrowers.  To the fullest extent permitted by
applicable law, each Borrower expressly waives any suretyship defenses or
benefits that it otherwise might or would have under applicable law.  WITHOUT
LIMITING THE GENERALITY OF ANY OTHER WAIVER OR OTHER PROVISION SET FORTH IN THIS
SECTION, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH BORROWER WAIVES
ALL RIGHTS AND DEFENSES ARISING OUT OF AN ELECTION OF REMEDIES BY THE BANK, EVEN
THOUGH THAT ELECTION OF REMEDIES, SUCH AS A NONJUDICIAL FORECLOSURE WITH RESPECT
TO SECURITY FOR THE OBLIGATIONS, HAS DESTROYED SUCH BORROWER'S RIGHTS OF
SUBROGATION AND REIMBURSEMENT AGAINST THE OTHER BORROWERS BY THE OPERATION LAW,
INCLUDING BUT NOT LIMITED TO SECTION 580d OF THE CODE OF CIVIL PROCEDURE, OR
OTHERWISE.

       Borrower and each of them warrant and agree that each of the waivers and
consents set forth herein are made after consultation with legal counsel and
with full knowledge of their significance and consequences, with the
understanding that events giving rise to any defense or right waived may
diminish, destroy or otherwise adversely affect rights which Borrower otherwise
may have against any other Borrower, the Bank or others, or against Collateral.
If any of the waivers or consents herein are determined to be contrary to any
applicable law or public policy, such waivers and consents shall be effective to
the maximum extent permitted by law.

BORROWER: OVERLAND DATA, INC.             LENDER:   IMPERIAL BANK

==============================================================================

PRINCIPAL AMOUNT: $5,000,000.00      INITIAL RATE: 8.500%
           DATE OF NOTE: NOVEMBER 10, 1999

PROMISE TO PAY. OVERLAND DATA, INC. ("BORROWER") promises to pay to Imperial
Bank ("LENDER"), or order, in lawful money of the United States of America,
the principal amount of Five Million $ 00/100 Dollars ($5,000,000.00) or so
much as may be outstanding, together with interest on the unpaid principal
balance of each advance. Interest shall be calculated from the date of each
advance until repayment of each advance.

PAYMENT:  Borrower will pay this loan in one payment of all outstanding
principal plus all accrued unpaid interest on November 5, 2001. In addition,
Borrower will pay regular monthly payments of accrued unpaid interest
beginning December 5, 1999, and all subsequent interest payments are due on
the same day of each month after that. The annual interest rate for this
Note is computed on a 365/360 basis; that is, by applying the ratio of the
annual interest rate over a year of 360 days, multiplied by the outstanding
principal balance, multiplied by the actual number of days he principal
balance is outstanding. Borrower will pay Lender a Lender's address shown
above or at such other place as Lender may designate in writing. Unless
otherwise agreed or required by applicable law, payments will be applied
first to any unpaid collection costs and any late charges, then to any unpaid
interest, and any remaining amount to principal.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change
from time to time based on changes in an index which is the Imperial Bank
Prime Rate (the "Index"). The Prime Rate is the rate announced by Lender as
its Prime Rate of interest from time to time. Lender will tell Borrower the
current index rate upon Borrower's request. Borrower understands that Lender
may make loans based on other rates as well. The interest rate change will
not occur more often than each day. THE INDEX CURRENTLY IS 8.500%. THE
INTEREST RATE TO BE APPLIED TO THE UNPAID PRINCIPAL BALANCE OF THIS NOTE WILL
BE AT A RATE EQUAL TO THE INDEX, RESULTING IN AN INITIAL RATE OF 8.500%.
NOTICE: Under no circumstances will the interest rate on this Note be more
than the maximum rate allowed by applicable law.

PREPAYMENT: MINIMUM INTEREST CHARGE. Borrower agrees that all loan fees and
other prepaid finance charges are earned fully as of the date of the loan and
will not be subject to refund upon early payment (whether voluntary or as a
result of default), except as otherwise required by law. In any event, even
upon full prepayment of this Note, Borrower understands that Lender is
entitled to A MINIMUM INTEREST CHARGE OF $250.00. Other than borrower's
obligation to pay any minimum interest charge, Borrower may pay without
penalty all or a portion of the amount owed earlier than it is due. Early
payments will not, unless agreed to by Lender in writing, relieve Borrower of
Borrower's obligation to continue to make payments of accrued unpaid
interest. Rather, they will reduce the principal balance due.

LATE CHARGE. If a payment is 10 DAYS OR MORE LATE, Borrower will be charged
5.000% of the unpaid portion of the regularly scheduled payment.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform
when due any other term, obligation, covenant, or condition contained in this
Note or any agreement related to this Note, or in any other agreement or loan
Borrower has with Lender. (c) Any representation or statement made or
furnished to Lender by Borrower or on Borrower's behalf is false or
misleading in any material respect either now or at the time made or
furnished. (d) Borrower becomes insolvent, a receiver is appointed for any
part of Borrower's property, Borrower makes an assignment for the benefit of
creditors, or any proceeding is commenced either by Borrower or against
Borrower under any bankruptcy or insolvency laws. (e) Any creditor tries to
take any of Borrower's property on or in which Lender has a lien or security
interest. This includes a garnishment of any of Borrower's accounts with
Lender. (f) Any guarantor dies or any of the other events described in this
default section occurs with respect to any guarantor of this Note. (g) A
material adverse change occurs in Borrower's financial condition, or Lender
believes the prospect of payment or performance of the indebtedness is
impaired. (h) Lender in good faith deems itself insecure.

If any default, other than a default in payment, is curable and if Borrower
has not been given a notice of a breach of the same provision of this Note
within the preceding twelve (12) months, it may be cured (and no event of
default will have occurred) if Borrower, after receiving written notice from
Lender demanding cure of such default: (a) cures the default within ten (10)
days; or (b) if the cure requires more than ten (10) days, immediately
initiates steps which Lender deems in Lender's sole discretion to be
sufficient to cure the default and thereafter continues and completes all
reasonable and necessary steps sufficient to produce compliance as soon as
reasonably practical.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount. Upon Borrower's failure to
pay all amounts declared due pursuant to this section, including failure to
