OVERVIEW

     During the 2007 fiscal year, SAND continued its process, started in
previous years, of engaging integrator and systems partners in active sales
situations for its high-performance analytical application products. In
particular, the SAND Searchable Archive product (now named SAND/DNA Access)
began to gain traction and mindshare as a method for managing growth in data
warehouse environments in a fashion that is very complementary to existing
industry standards. In conjunction with partners like SAP, the company has
readied specific application offerings, using this exciting product, to make it
easy to adopt. During 2007, the company launched the SAND/DNA brand for its
products in conjunction with the SAP offering with high interest from industry
analysts, partners, and prospective customers.

                                        7

     Despite the growing conditioning of the market to its new solutions to
intelligent information management, the company recognizes the potentially
lengthy sales cycles required to gain strong market acceptance of these new
approaches, and therefore significantly lowered its expense rate. At the same
time it engaged refined skills in the area of Marketing and Business Development
geared towards the SAND/DNA applications.

     The result in the first half of this Fiscal Year (2008) was the
continuation of a significant reduction in operating losses although sales have
decreased slightly. While we expect that our new solutions will only start
contributing to revenues and profits later this year and the beginning of the
next fiscal year, we are encouraged by the trends in our financial performance
which should only improve further as they come to stream.

RESULTS OF OPERATIONS

SECOND QUARTER OF FISCAL 2008 COMPARED WITH SECOND QUARTER OF FISCAL 2007 AND
FIRST HALF OF FISCAL 2008 COMPARED WITH FIRST HALF OF FISCAL 2007

Revenue

     Sales revenue for the second quarter ended January 31, 2008 was $1,419,521,
a decrease of 24% from sales of $1,861,658 for the second quarter ended January
31, 2007. In North America, sales were $530,646, an increase of 57% from sales
of $337,751 in the second quarter of fiscal 2007. In Europe, sales in the second
quarter of fiscal 2008 were $888,875, a decrease of 42% from sales of $1,523,907
in the second quarter of fiscal 2007.

     Sales revenue for the first half of fiscal 2008 was $3,204,446, a decrease
of 4% from sales of $3,332,065 for the first half of fiscal 2007. In North
America sales were $1,240,315, an increase of 34% from sales of $928,523 in the
first half of fiscal 2007. In Europe, sales in the first half of fiscal 2008
were $1,964,131, a decrease of 18% from sales of $2,403,542 in the first half of
fiscal 2007.

     In North America the increase in our revenues can be explained primarily by
the increased sales from our alliances during the first half of fiscal 2008. In
Europe the decrease is associated primarily to delays in the procurement process
from some opportunities.

     We recognize revenues from software licenses in accordance with the
provisions of the American Institute of Certified Public Accountants Statement
of Position 97-2, which requires that companies defer revenue and profit
recognition if four specified criteria of a sale are not met. In addition, we
are required to allocate revenue to multiple element arrangements. We typically
contract professional services on a time-and-materials basis and such revenues
are recognized as services when they are performed. Revenues from support and
maintenance are recognized rateably over the term of the applicable support and
maintenance agreement.

Selling, General and Administrative Expenses

     Selling, general and administrative expenses include salaries, commissions
and other personnel-related costs, the impact of foreign exchange gains and
losses, travel expenses, advertising programs and other promotional activities
associated with the selling and marketing of our products and services. Selling,
general and administrative expenses decreased by 26% to $926,242 for the second
quarter ended January 31, 2008 from $1,248,635 for the second quarter ended
January 31, 2007. For the first half of fiscal 2008, selling, general and
administrative expenses were $1,920,016 compared to $2,495,350 during the first
half of fiscal 2007, a decrease of 23%.

Research and Development Expenses

     Research and development expenses consist primarily of salaries and other
personnel-related costs of technical and engineering personnel associated with
our research and product development activities, including the enhancement and
localization of existing products, quality assurance and testing as well as the
cost of materials and equipment used in research and development activities.
Research and development expenses decreased by 15% to $498,179 for the second
quarter ended January 31, 2008 from $584,086 for the second quarter ended
January 31, 2007. For the first half of fiscal 2008, research and development
expenses were $1,090,676 compared to $1,159,952 during the first half of fiscal
2007, a decrease of 6%. For the remainder of fiscal 2008, we expect that
Research and Development expenditures will not vary significantly in absolute
dollars.

Cost of Sales

     Cost of sales consists primarily of the costs related to the sale of
third-party software, including certain license fees and royalties, as well as
the costs related to systems architects who assist clients to implement systems
and provide support services. Cost of sales decreased by 17% to $387,191 for the
second quarter ended January 31, 2008 from $466,315 for the second quarter ended
January 31, 2007. For the first half of fiscal 2008, cost of sales was $799,355
compared to $899,990 during the first half of fiscal 2007, a decrease of 11%.
The decrease for the first half of fiscal 2008 reflects in part the decrease in
revenue. Cost of revenues from services may vary due to the mix of services
provided by SAND's personnel relative to services provided by outside
consultants and to varying levels of expenditures necessary to build the service
sector.

Operations

     SAND generated a net loss of $491,343 in the second quarter ended January
31, 2008 as compared to a net loss of $489,095 in the second quarter ended
January 31, 2007. Net loss was $796,263 in the first half of fiscal 2008 as
compared to a net loss of $1,325,627. These results reflect the transitional
nature of the business and distribution model of SAND, as it moves progressively
towards being profitable. We believe that this transition is likely to continue
during the next few quarters.

Liquidity and Capital Resources

     Cash and investments as at January 31, 2008 were $62,643 compared with
$348,997 as at January 31, 2007. SAND does not have a line of credit with a
commercial bank. In light of

                                        9

operating losses suffered in the current and past years, the Corporation's
ability to realize its assets and discharge its liabilities depends on the
continued financial support of its shareholders and creditors and its ability to
obtain additional financing. The Corporation's management will continue to
search for additional sources of debt and equity financing. There can be no
assurance that the Corporation's activities will be successful and as a result
there is doubt regarding the going concern assumption.

SAND TECHNOLOGY INC.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(IN CANADIAN DOLLARS)
(UNAUDITED)

The Corporation is involved in the design, development, marketing and support of
software products and services that enable users to retrieve usable business
information from large amounts of data. The software products, collectively
known as the SAND/DNA and the SAND/DNA Analytics, are designed to provide an
efficient and cost-effective way for business users to make fast easy inquiries
of large databases without the intervention of specialist Information Technology
professionals. The Corporation is considered to have only one reportable
business segment.

1.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       BASIS OF PRESENTATION

       The financial statements have been prepared in accordance with Canadian
       generally accepted accounting principles and on the basis of the going
       concern assumption, meaning that it is assumed that the Corporation will
       be able to realize its assets and discharge its liabilities in the normal
       course of operations.

       In light of operating losses suffered in the current and past years, the
       Corporation's ability to realize its assets and discharge its liabilities
       depends on the continued financial support of its shareholders and
       creditors and its ability to obtain additional financing. The
       Corporation's management will continue to search for additional sources
       of debt and equity financing.

       There can be no assurance that the Corporation's activities will be
       successful and as a result there is doubt regarding the "going concern"
       assumption. These consolidated financial statements do not reflect
       adjustments that would be necessary if the "going concern" assumption was
       not appropriate. The adjustments to the carrying values of the assets and
       liabilities, the reported expenses and the balance sheet classifications,
       which could be material, may be necessary for these consolidated
       financial statements.

       USE OF ESTIMATES

       These financial statements have been prepared in accordance with Canadian
       generally accepted accounting principles, which require management to
       make estimates and assumptions that affect the reported amounts of assets
       and liabilities and the disclosure of contingent liabilities at the date
       of the financial statements, and the reported amounts of revenue and
       expenses during the reporting period. Actual results could differ from
       those estimates.

       These unaudited interim consolidated financial statements do not include
       all disclosures required for annual financial statements and should be
       read in conjunction with the most recent annual financial statements as
       at and for the year ended July 31, 2007.

       BASIS OF CONSOLIDATION

       The consolidated financial statements include the accounts of the
       Corporation and its wholly-owned subsidiaries. All inter-company
       transactions and balances have been eliminated.

1.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

       REVENUE RECOGNITION

       The Corporation generates revenues principally through two sources:
       software licences and services. Software licence revenues are normally
       generated from licensing the perpetual use of the Corporation's software
       products. Service revenues are generated from sales of maintenance,
       implementation, consulting and training services performed for customers
       that licence the Corporation's products.

       Revenue from the sale of software licence agreements are recognized upon
       delivery of software if persuasive evidence of an arrangement exists,
       collection is probable, the fee is fixed or determinable and
       vendor-specific evidence of an arrangement exists to allocate the total
       fee to the different elements of an arrangement. Vendor-specific
       objective evidence is typically based on the price charged when an
       element is sold separately, or, in the case of an element not yet sold
       separately, the price established by management, if it is probable that
       the price, once established, will not change before market introduction.

       In circumstances where the implementation services are essential to the
       functionality of the software or where the software requires significant
       customization, the Corporation recognizes software licence revenue using
       the percentage-of-completion method over the implementation period. The
       percentage-of-completion is measured by the percentage of implementation
       hours incurred to date to estimated implementation hours. Past experience
       has shown expended hours to be the best measure of progress.

       Revenues from maintenance services for licences previously sold and
       implemented are recognized rateably over the terms of the contract.

       Revenue from consulting and training services, not considered as part of
       the implementation of software licences, are recognized as the services
       are provided.

       Amounts received in advance of the delivery of products or the
       performance of services are classified as deferred revenue.

       CASH AND CASH EQUIVALENTS

       Cash and cash equivalents include unrestricted cash and highly liquid
       investments.

       CAPITAL ASSETS

       Capital assets are recorded at cost and are amortized over their
       estimated useful lives using the straight-line method over the following
       periods:

       OTHER ASSETS

       Other assets comprise contract costs. Contract costs are comprised of an
       amount paid to the vendor upon the transfer of a long-term service
       contract and will be amortized rateably over the term of the contract.

       RESEARCH AND DEVELOPMENT COSTS

       Research costs are charged to operations in the period in which they are
       incurred. Development costs are expensed as incurred unless a project
       meets the criteria under Canadian generally accepted accounting
       principles for deferral and amortization. The Corporation has not
       deferred any such development costs to date. Related tax credits are
       recorded as a reduction of research and development expenses.

       INCOME TAXES

       Income taxes are accounted for using the liability method of tax
       allocation. Future income tax assets and liabilities are determined based
       on deductible or taxable temporary differences between the financial
       statement values and tax values of assets and liabilities, using enacted
       income tax rates expected to be in effect for the year in which the
       differences are expected to reverse.

       DEFERRED CREDITS

       Deferred credits include deferred lease inducements, which are amortized
       on a straight-line basis over the term of the lease.

       FOREIGN EXCHANGE TRANSLATION

       Revenue, expenses and acquisition of non-monetary assets denominated in
       foreign currencies are translated into Canadian dollars at rates
       prevailing on the transaction dates. Monetary assets and liabilities are
       translated at rates in effect at the balance sheet date.

       The accounts of the subsidiaries included in the consolidated financial
       statements are translated into Canadian dollars using the temporal
       method. Under this method, monetary items are translated at exchange
       rates in effect at the balance sheet dates; non-monetary assets are
       translated at historical exchange rates. Revenue and expenses are
       translated at average exchange rates for the period, with the exception
       of amortization of assets, which is translated at the same historical
       exchange rates as the related assets. Translation losses and gains are
       included in operations.

1.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

       LOSS PER SHARE

       Per share computations are based on the weighted average number of shares
       outstanding during the period. The dilutive effect of options is
       determined using the treasury stock method.

       STOCK-BASED COMPENSATION AND OTHER STOCK-BASED PAYMENTS

       The Corporation accounts for stock-based compensation under the
       recommendations of Section 3870 of the Canadian Institute of Chartered
       Accountants (CICA) Handbook, STOCK-BASED COMPENSATION AND OTHER
       STOCK-BASED PAYMENTS, which sets standards for recognizing, measuring and
       disclosing stock-based compensation and other stock-based payments made
       in exchange for goods and services. The standards require the Corporation
       to use a fair-value based method for all stock-based awards and the
       recognition of an expense in the financial statements. See Note 5, stock
       option plan, for additional information.

       GUARANTEES

       In the normal course of its operations, the Corporation has entered into
       agreements that contain certain features which meet the definition of a
       guarantee under the guidance provided by Accounting Guideline 14.

       Certain agreements with its customers include intellectual-property
       indemnification obligations that are customary in the industry. These
       obligations would generally require the Corporation to compensate a third
       party for certain damages and claims incurred as a result of third-party
       intellectual-property claims arising from these agreements.

       The nature of these obligations prevents the Corporation from making a
       reasonable estimate of the maximum potential amount it could be required
       to pay. Historically, the Corporation has not made any payments under
       such obligations. The adoption of these recommendations did not have an
       impact on the Corporation's consolidated financial statements.

       NEW ACCOUNTING POLICIES ADOPTED

       STOCK-BASED COMPENSATION FOR EMPLOYEES ELIGIBLE TO RETIRE BEFORE THE
       VESTING DATE

       In July 2006, the Emerging Issues Committee (EIC) of the CICA issued
       EIC-162, "Stock-based Compensation for Employees Eligible to Retire
       before the Vesting Date". EIC-162 clarifies the accounting for
       compensation costs relating to stock-based awards granted to employees.
       EIC-162 requires that i) compensation costs attributable to stock-based
       awards granted to employees who are eligible to retire on the grant date
       be recognized on the grant date, and ii) compensation cost attributable
       to stock-based awards granted to employees who will become eligible to
       retire during the vesting period be recognized over the period from the
       grant date to the date of retirement eligibility. This abstract is to be
       applied retroactively, with restatement of prior periods, and is
       effective for interim periods beginning on or after December 1, 2006. The
       adoption of EIC-162 did not have a material impact on the Corporation's
       financial statements

4.     DUE TO A SHAREHOLDER

       During the year 2007, the Corporation formalized the conditions
       pertaining to a loan obtained from a significant shareholder who is also
       the President and Chief Executive Officer. The loan is repayable within
       90 days of the receipt of a written demand from the shareholder. The loan
       bears interest at 15%. In conjunction with the ratification of the loan
       agreement, the Corporation also issued 103,061 warrants, each warrant
       entitling to purchase one class "A" common share of the Corporation at a
       price of US$0.44 per share and is valid for the term of the agreement.
       The residual valuation method was used to allocate the proceeds between
       the liability component and the equity component. The value of the
       liability component was determined to be the face value of the debt
       because there is no maturity date and by difference, the value of the
       equity instrument was determined to be nil.

5.     COMMON STOCK

       (a) AUTHORIZED

       Unlimited number of Class "A" common shares without par value.

       (b) STOCK OPTION PLANS

       The company has two stock option plans. Under the 1996 Stock Incentive
       Plan, the Company may grant options to its regular full-time employees
       and those of its subsidiaries for up to a maximum of 1,100,000 common
       shares. Under the 1996 Stock Option Plan, the Company may grant options
       to its regular full-time employees directors and those of its
       subsidiaries for up to a maximum of 900,000 common shares. Under both
       plans, the exercise price of each option is not less than the market
       price of the Company's shares on the Nasdaq National Market System or
       since August 9, 2005 on the OTC Bulletin Board

       (c) SHARE AWARD PLAN

       On November 2, 2006, the Board of Directors of SAND established a Share
       Award Plan pursuant to which up to 1,000,000 Common Shares of the
       Corporation shall be issuable under the Share Award Program through
       direct and immediate issuances without any intervening option grants.

       On August 28, 2007, the Board of Directors of the Corporation authorized
       the award of up to 665,000 Common Shares. Since then, the Corporation has
       awarded 652,500 Common Shares including grants which are dependant on the

       the Award Recipient is in the employ of the Corporation on the vesting
       date of September 30, 2010 or upon a change in control of the

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(IN CANADIAN DOLLARS)
(UNAUDITED)

9.     FINANCIAL INSTRUMENTS

       FAIR VALUE OF FINANCIAL INSTRUMENTS

       As at January 31, 2008, the estimated fair market value of cash and cash
       equivalents, accounts receivable, loan and accounts payable and accrued
       liabilities is equal to the book value, given the short-term nature of
       these items.

       CREDIT RISK

       The Corporation's exposure to credit risk as of January 31, 2008, is
       equal to the carrying amount of its financial assets.

       CONCENTRATION OF CREDIT RISK

       Credit risk concentration with respect to trade receivables is limited
       due to the relatively large size of the Corporation's customers.

       CURRENCY RISK

       The Corporation operates internationally and is exposed to market risk
       principally from changes in foreign currency rates. The Corporation does
       not hold any financial instruments that mitigate this risk.
