DISTRIBUTION AGREEMENT

This DISTRIBUTION AGREEMENT (the “Agreement”) is made as of September 30, 2019 by and between BlackRock Science and Technology Trust, a Delaware statutory trust (the “Trust”), and BlackRock Investments, LLC, a Delaware limited liability company (the “Distributor”).

WITNESSETH:

WHEREAS, the Trust is registered under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder (collectively called the “Investment Company Act”), as a non-diversified, closed-end, management investment company; and

WHEREAS, the Trust has filed, or may from time to time file, one or more registration statements on Form N-2 pursuant to the Investment Company Act and the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively called the “Securities Act”), to register additional common shares of the Trust, which may be issued and sold from time to time through various specified transactions, including at-the-market (“ATM”) offerings pursuant to Rule 415 under the Securities Act; and

WHEREAS, the Distributor is registered as a broker-dealer under the provisions of the Securities Exchange Act of 1934 (the “Exchange Act”) and is a member in good standing of the Financial Industry Regulatory Authority, Inc. (“FINRA”); and

WHEREAS, the Trust and the Distributor wish to enter into an agreement with each other with respect to ATM offerings, from time to time, of the Trust’s common shares.

NOW THEREFORE, the parties agree as follows:

Section 1. Appointment of the Distributor; ATM Offerings.

(a) Subject to the terms and conditions of this Agreement, the Trust hereby appoints the Distributor as its principal underwriter and placement agent for the common shares of the Trust to be offered pursuant to a Registration Statement (as defined below) through ATM offerings from time to time (the “Shares”) and the Trust agrees that it will issue such Shares as the Distributor may sell. The Distributor agrees to use reasonable efforts to identify opportunities for the sale of Shares, but the Distributor is not obligated to sell any specific number of the Shares (though the Distributor will only be authorized to sell on any Offering Date (as defined below) the maximum number of Shares agreed to with the Trust pursuant to Section 1(d) hereof) or purchase any Shares for its own account. The Shares will only be sold on such days as shall be agreed to by the Distributor and the Trust (each, an “Offering Date”). The Distributor hereby accepts such appointment.

(b) The Distributor acknowledges that Shares will be offered and sold only as set forth from time to time in a Registration Statement including, without limitation, pricing of Shares, handling of investor funds and payment of sales commissions.

(c) The Trust may suspend or terminate any ATM offering of its Shares at any time. Upon notice to the Distributor of the terms of such suspension or termination, the Distributor shall suspend the ATM offering of Shares in accordance with such terms until the Trust notifies the Distributor that such ATM offering may be resumed; provided, however, that such suspension or termination shall not affect or impair the parties’ respective obligations with respect to the Shares sold hereunder prior to the giving of such notice.

(d) The price per Share shall be determined by the Trust together with the Distributor by reference to trades on the Trust’s primary exchange. In no event shall the price per Share be less than the current net asset value per Share plus the per Share amount of the commission to be paid to the Distributor (the “Minimum Price”). The Trust may establish a minimum sales price per Share on any Offering Date in excess of the Minimum Price (the “Minimum Sales Price”), and the Trust shall communicate such Minimum Sales Price to the Distributor. The Trust shall have sole discretion to establish a Minimum Sales Price for any Offering Date and may consider, among other factors, the degree to which the Trust’s market price per Share exceeds its net asset value per Share, and the amount of assets the Trust desires to raise through ATM offerings. The Distributor shall suspend the sale of Shares if the per share price of the Shares is less than the Minimum Price or the Minimum Sales Price. The Distributor shall, together with the Trust, determine the maximum number of Shares to be sold by the Distributor for any Offering Date, and the Distributor shall not be authorized to sell Shares on any Offering Date in excess of such maximum.

(e) The Distributor will confirm to the Trust, following the close of trading on the Trust’s primary exchange on each Offering Date for the Shares, the number of Shares sold, the time of sale, the gross sales price per Share and the compensation payable to the Distributor, or to which the Distributor is entitled with respect to such sales. The Trust reserves the right to reject any order in whole or in part.

(f) Settlement for sales of the Shares pursuant to this Section 1 will occur on the second business day following the date on which such sales are made (each such day, a “Settlement Date”). On each Settlement Date, the Shares sold through the Distributor for settlement on such date shall be delivered by the Trust to the Distributor against payment of the gross sales proceeds for the sale of such Shares, less the Distributor’s sales commission.

(g) In selling Shares, the Distributor shall act solely as an agent of the Trust and not as principal.

Section 2. Representations and Warranties by the Trust. The Trust represents, warrants to and agrees with the Distributor, as of the date hereof and as of each Offering Date and Settlement Date, that:

(a) The Registration Statement pursuant to which Shares are sold (i) has been prepared by the Trust in conformity with the requirements of the Securities Act and the Investment Company Act in all material respects; (ii) has been filed with the U.S. Securities and Exchange Commission (the “Commission”) under the Securities Act and the Investment Company Act; and (iii) heretofore became, and is, effective; such Registration Statement sets forth the terms of the offering, sale and plan of distribution of the Shares and contains additional information concerning the Trust and its business; no stop order of the Commission preventing or suspending the use of any Prospectus (as defined below), or the effectiveness of such Registration Statement, has been issued, and no proceedings for such purpose have been instituted or, to the Trust’s knowledge, have been threatened by the Commission. Except where the context otherwise requires, “Registration Statement,” as used herein, means, collectively, the

- 2 -

various parts of a registration statement pertaining to the offering and sale of Shares, as amended, at the time of effectiveness for purposes of Section 11 of the Securities Act (the “Effective Time”), as such section applies to the Distributor, including (1) all documents filed as a part thereof or incorporated or deemed to be incorporated by reference therein, and (2) any information contained or incorporated by reference in a prospectus filed with the Commission pursuant to Rule 497(c) and/or Rule 497(h) under the Securities Act, to the extent such information is deemed to be part of such Registration Statement at the Effective Time. Except where the context otherwise requires, “Prospectus,” as used herein, means a final prospectus, including the related statement of additional information, relating to the Shares, filed by the Trust with the Commission pursuant to Rule 497(c) and/or Rule 497(h) under the Securities Act, in the form furnished by the Trust to the Distributor in connection with the offering of the Shares, together with, if applicable, any final prospectus supplement relating to the Shares attached to or used with such final prospectus, filed by the Trust with the Commission pursuant to Rule 497(c) and/or Rule 497(h) under the Securities Act, in the form furnished by the Trust to the Distributor in connection with the offering of the Shares.

- 3 -

(d) The financial statements incorporated by reference in the Registration Statement or the Prospectus, together with the related notes and schedules, present fairly the financial position of the Trust as of the dates indicated and the results of operations, cash flows and changes in shareholders’ equity of the Trust for the periods specified and have been prepared in compliance in all material respects with the requirements of the Securities Act, the Investment Company Act and the Exchange Act, and in conformity in all material respects with U.S. generally accepted accounting principles applied on a consistent basis during the periods involved; the other financial and statistical data contained or incorporated by reference in the Registration Statement or the Prospectus are accurately and fairly presented, in all material respects, and prepared on a basis consistent with the financial statements and books and records of the Trust in all material respects; there are no financial statements that are required to be included or incorporated by reference in the Registration Statement or the Prospectus by the Securities Act, the Investment Company Act or the Exchange Act that are not included or incorporated by reference as required; and the Trust does not have any material liabilities or obligations, direct or contingent (including any off-balance sheet obligations), not described in the Registration Statement (excluding the exhibits thereto).

(e) As of the date of this Agreement, the Trust has an authorized and outstanding capitalization as set forth in the Registration Statement and the Prospectus and, with respect to any issuance and sale under this Agreement, the Trust shall have as of the date of the most recent amendment or supplement to the Registration Statement or Prospectus, an authorized and outstanding capitalization as set forth in the Registration Statement and the Prospectus; all of the issued and outstanding shares of capital stock, including the Shares, of the Trust have been duly authorized and validly issued and are fully paid and non-assessable (except as described below and in the Registration Statement), have been issued in material compliance with all applicable securities laws and were not issued in violation of any preemptive right, resale right, right of first refusal or similar right; the Shares will be duly listed, and admitted and authorized for trading, subject to official notice of issuance, on the exchange on which the Trust’s Shares are listed and primarily trade (the “Stock Exchange”).

(f) The Trust has been duly formed, is validly existing and is in good standing under the laws of Delaware, with full power and authority to own, lease and operate and conduct its business as described in the Registration Statement and the Prospectus and to issue, sell and deliver the Shares as contemplated herein. The Trust is duly qualified to do business as a foreign entity and is in good standing in each jurisdiction where the conduct of its business requires such qualification, except where the failure to be so qualified and in good standing would not, individually or in the aggregate, have a material adverse effect on the business, properties, financial condition or results of operations of the Trust.

(g) The Shares have been duly and validly authorized and, when issued and delivered against payment therefor as provided herein, will be duly and validly issued, fully paid and non-assessable (except as described below and in the Registration Statement) and free of statutory and contractual preemptive rights, resale rights, rights of first refusal and similar rights; the Shares, when issued and delivered against payment therefor as provided herein, will be free of any restriction upon the voting or transfer thereof pursuant to the Trust’s agreement and declaration of trust or bylaws or any agreement or other instrument to which the Trust is a party.

(a) The Trust shall take, from time to time, but subject always to any necessary approval of the Board of Trustees of the Trust (each a “Trustee,” and together the “Board”) or of its shareholders, all necessary action to fix the number of authorized Shares, to the end that the Trust will have a number of authorized but unissued Shares at least equal to the number of Shares registered for sale under the Securities Act and available for sale pursuant to the Registration Statement.

(b) For purposes of the ATM offerings of Shares, the Trust will furnish to the Distributor copies of its most recent amendment to its Registration Statement for a particular ATM offering, its most recent Prospectus and all amendments and supplements thereto, and other documentation the Distributor may reasonably request for use in the ATM offerings of Shares.

Section 4. Duties of the Distributor.

(a) The Distributor shall devote reasonable time and effort to its duties hereunder.

Notwithstanding anything in this Agreement to the contrary, the Distributor’s cumulative liability to the Trust and any person or entity claiming through the Trust for all losses, claims, suits, controversies, breaches and damages of any nature whatsoever arising out of or relating to this Agreement, and regardless of the form of action or legal theory, shall not exceed an amount equal to the greatest amount of fees received by the Distributor for services provided under this Agreement during a particular six (6) consecutive month period. The Distributor shall not be liable for any damages arising out of any action or omission to act by any prior service provider of the Trust or for any failure to discover any such error or omission (provided that this sentence shall not apply where the Distributor was the prior service provider). Notwithstanding anything in this Agreement to the contrary, the Distributor shall not be liable for any consequential, incidental, exemplary, punitive, special or indirect damages, whether or not the likelihood of such damages was known by the Distributor. Notwithstanding anything in this Agreement to the contrary, the Distributor shall not be liable for damages occurring directly or indirectly by reason of circumstances beyond its reasonable control.

(b) The Trust agrees that it will indemnify, defend and hold harmless the Distributor, its

- 8 -

several officers, and directors, and any person who controls the Distributor within the meaning of Section 15 of the Securities Act, from and against any losses, claims, damages or liabilities, joint or several, to which the Distributor, its several officers, and directors, and any person who controls the Distributor within the meaning of Section 15 of the Securities Act, may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) (i) arise out of, or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectuses or in any application or other document executed by or on behalf of the Trust or are based upon information furnished by or on behalf of the Trust filed in any state in order to qualify the Shares under the securities or blue sky laws thereof (“Blue Sky application”) or arise out of, or are based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) arise out of, or are based upon, any breach of the representations, warranties or covenants of the Trust contained in this Agreement, and the Trust will reimburse the Distributor, its several officers, and directors, and any person who controls the Distributor within the meaning of Section 15 of the Securities Act, for any legal or other expenses reasonably incurred by the Distributor, its several officers, and directors, and any person who controls the Distributor within the meaning of Section 15 of the Securities Act, in investigating, defending or preparing to defend any such action, proceeding or claim described above in this Section 8(b); provided, however, that the Trust shall not be liable in any case to the extent that such loss, claim, damage or liability arises out of, or is based upon, any untrue statement, alleged untrue statement, or omission or alleged omission made in the Registration Statement, the Prospectus or any Blue Sky application with respect to the Trust in reliance upon and in conformity with any Agent Provided Information, or arising out of the failure of the Distributor or any sub-placement agent to deliver a current Prospectus.

(c) The Trust shall not indemnify any person pursuant to this Section 8 unless the court or other body before which the proceeding was brought has rendered a final decision on the merits that such person was not liable by reason of his or her willful misfeasance, bad faith or gross negligence in the performance of his or her duties, or his or her reckless disregard of any obligations and duties, under this Agreement (“disabling conduct”) or, in the absence of such a decision, a reasonable determination (based upon a review of the facts) that such person was not liable by reason of disabling conduct has been made by the vote of a majority of a quorum of the trustees of the Trust who are neither “interested parties” (as defined in the Investment Company Act) nor parties to the proceeding, or by independent legal counsel in a written opinion.

(d) The Distributor will indemnify and hold harmless the Trust and its several officers and trustees, and any person who controls the Trust within the meaning of Section 15 of the Securities Act, from and against any losses, claims, damages or liabilities, joint or several, to which any of them may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus or any Blue Sky application, or arise out of, or are based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, which statement or omission was made in reliance upon and in conformity with information furnished in writing to the Trust or any of its several officers and trustees by or on behalf of the Distributor specifically for inclusion therein, and will reimburse the Trust and its several officers, trustees and such controlling persons for any legal or other expenses reasonably incurred by any of them in investigating, defending or preparing to defend any such action, proceeding or claim.

(e) This Section 8 shall survive any termination of this Agreement.

- 9 -

Section 9. Duration and Termination of this Agreement.

(a) This Agreement shall become effective as of the date first above written and shall remain in force for two years thereafter and thereafter continue from year to year, but only so long as such continuance is specifically approved at least annually (i) by the Trustees or by the vote of a majority of the outstanding voting securities of the Trust, and (ii) by the vote of a majority of those Trustees who are not parties to this Agreement or interested persons of any such party cast in person at a meeting called for the purpose of voting on such approval.

(b) This Agreement may be terminated at any time, without the payment of any penalty, by the Trustees or by vote of a majority of the outstanding voting securities of the Trust, or by the Distributor, on sixty days’ written notice to the other party. This Agreement shall automatically terminate in the event of its assignment.

(c) The terms “vote of a majority of the outstanding voting securities,” “assignment,” “affiliated person” and “interested person,” when used in this Agreement, shall have the respective meanings specified in the Investment Company Act.

Section 10. Amendments of this Agreement. This Agreement may be amended by the parties only if such amendment is specifically approved (i) by the Trustees or by the vote of a majority of the outstanding voting securities of the Trust and (ii) by the vote of a majority of those Trustees of the Trust who are not parties to this Agreement or interested persons of any such party cast in person at a meeting called for the purpose of voting on such approval.

To the extent that the applicable law of the State of New York, or any of the provisions herein, conflict with the applicable provisions of the Investment Company Act, the latter shall control.

Section 12. Customer Identification Program Notice. To help the U.S. government fight the funding of terrorism and money laundering activities, U.S. federal law requires each financial institution to obtain, verify, and record certain information that identifies each person who initially opens an account with that financial institution on or after October 1, 2003. Consistent with this requirement, the Distributor will request (or already has requested) the Trust’s name, address and taxpayer identification number or other government-issued identification number. The Distributor may also ask (and may have already asked) for additional identifying information, and the Distributor may take steps (and may have already taken steps) to verify the authenticity and accuracy of these data elements.

Section 13. Miscellaneous. The captions in this Agreement are included for convenience of reference only and in no way define or delimit any of the provisions hereof or otherwise affect their construction or effect. If any provision of this Agreement shall be held or made invalid by a court decision, statute, rule or otherwise, the remainder of this Agreement shall not be affected thereby. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors.

- 10 -

Section 14. Proprietary and Confidential Information. The Distributor agrees on behalf of itself and its employees to treat confidentially and as proprietary information of the Trust all records and other information relative to the Trust and prior, present or potential shareholders, and not to use such records and information for any purpose other than performance of its responsibilities and duties hereunder, except after prior notification to and approval in writing by the Trust, which approval shall not be unreasonably withheld and shall not be required where the Distributor may be exposed to civil or criminal contempt proceedings for failure to comply, when requested to divulge such information by duly constituted authorities, or when so requested by the Trust. The provisions of this Section 14 shall survive termination of this Agreement.

Notwithstanding anything in this Agreement to the contrary, each party hereto agrees that: (i) any Nonpublic Personal Information, as defined under Section 248.3(t) of Regulation S-P (“Regulation S-P”), promulgated under the Gramm-Leach-Bliley Act (the “Act”), disclosed by a party hereunder is for the specific purpose of permitting the other party to perform the services set forth in this Agreement, and (ii) with respect to such information, each party will comply with Regulation S-P and the Act and will not disclose any Nonpublic Personal Information received in connection with this Agreement to any other party, except to the extent as necessary to carry out the services set forth in this Agreement or as otherwise permitted by Regulation S-P or the Act.

New York, New York 10019

Ladies and Gentlemen:

From time to time BlackRock Investments, LLC (the “Distributor,” “we” or “us”) will act as manager of registered at-the-market offerings by BlackRock Science and Technology Trust, a Delaware statutory trust (the “Fund”), of up to 13,000,000 common shares (the “Shares”) of beneficial interest, par value $0.001 per share, of the Fund (the “Common Shares”). In the case of such offerings, the Fund has agreed with the Distributor to issue and sell through or to the Distributor, as sales agent and/or principal, the Shares (the “Distribution Agreement”).

We hereby agree to retain UBS Securities LLC (the “Agent” or “you”) as a sub-placement agent with respect to the offerings of the Shares to be issued and sold by the Fund (the “Offerings”) as the Fund and the Distributor may indicate from time to time, and you agree to act in such capacity, all upon, and subject to, the terms and conditions set forth below:

SECTION 1. Description of Offerings.

(a) The Shares are to be sold on a daily basis or otherwise as shall be agreed to by the Fund and the Distributor on any day (each, an “ Offering Date”) that is a trading day for the exchange on which the Fund’s Shares are listed and primarily trade (the “Stock Exchange”) (other than a day on which the Stock Exchange is scheduled to close prior to its regular weekday closing time). Promptly after the Fund and the Distributor have determined the maximum amount of the Shares to be sold by the Distributor for any Offering Date, which shall not in any event exceed the amount available for issuance under the currently effective Registration Statement (as defined below) (the “Maximum Daily Amount”), and the minimum price per Share below which the Shares may not be sold by the Agent on any Offering Date (the “Minimum Daily Price”), the Distributor shall advise the Agent of the Maximum Daily Amount and the Minimum Daily Price. Subject to the terms and conditions hereof, the Agent shall use its reasonable best efforts to sell all of the Shares designated in accordance with the plan of distribution set forth in the Prospectus; provided, however, that in no event shall the Agent sell Shares in excess of the Maximum Daily Amount or for a price per Share below the Minimum Daily Price. The gross sales price of the Shares sold under this Section 1(a) shall be the market price at which the Agent sells such Shares.

(b) Notwithstanding the foregoing, the Distributor or the Fund may instruct the Agent by telephone (confirmed promptly by e-mail or telecopy) of a revised Minimum Daily Price and/or a revised Maximum Daily Amount and the Agent shall not sell Shares for a price per Share below such revised Minimum Daily Price, or in a quantity in excess of such revised Maximum Daily Amount, after the giving of such notice. In addition, the Distributor or the Fund may, upon notice to the Agent by telephone (confirmed promptly by e-mail or telecopy), suspend the offering of the Shares at any time; provided, however, that such suspension or termination shall not affect or impair the parties’ respective obligations with respect to the Shares sold hereunder prior to the giving of such notice.

(c) The Agent agrees not to make any sales of the Shares pursuant to this Section 1, other than through transactions for which compliance with Rule 153 under the Securities Act of 1933, as amended (the “Securities Act”), will satisfy the prospectus delivery requirements of Section 5(b)(2) of the Securities Act.

(d) The compensation to the Agent, as a sub-placement agent for each sale of the Shares pursuant to this Section 1, shall be the Applicable Selling Agent Commission with respect to the Shares sold, multiplied by the Gross Sales Proceeds (the “Agent Compensation”), as further described in the Addendum to this Sub-Placement Agent Agreement (the “Agreement”). The Agent shall not be responsible for any fees imposed by any governmental or self-regulatory organization on the Fund or the Distributor in respect of such sales. The Distributor may pay the Agent Compensation to the Agent, or may authorize the Agent to retain the Agent Compensation from the Gross Sales Proceeds. The Agent Compensation shall be payable solely out of the compensation the Distributor receives from the Fund pursuant to the Distribution Agreement (the “Related Compensation”). Notwithstanding anything to the contrary in any other provision of this Agreement (or, for the avoidance of doubt, in the Addendum hereto), the Distributor shall have no obligation to pay any portion of the Agent Compensation to the Agent, or authorize the retention by the Agent of any portion of the Agent Compensation from the Gross Sales Proceeds, until the Distributor receives at least an equivalent amount of Related Compensation, and the Distributor’s obligation to the Agent for the Agent Compensation is limited solely to amounts payable out of the Related Compensation.

(e) The Agent shall provide written confirmation to the Distributor following the close of trading on the Stock Exchange on each Offering Date setting forth for each sale the number of Shares sold, the time of sale, the Gross Sales Price per Share, and the compensation that the Agent is owed with respect to such sales.

(f) Settlement for sales of the Shares pursuant to this Section 1 will occur on the second business day following the date on which such sales are made (each such day, a “Settlement Date”), unless otherwise agreed to in writing by the parties hereto. On each Settlement Date, the Shares sold through the Agent for settlement on such date shall be delivered by the Distributor to the Agent against payment of the Gross Sales Proceeds for the sale of such Shares. Settlement for all such Shares shall be effected by free delivery of the Shares to the Agent’s account at The Depository Trust Company in return for payments in same day funds delivered to the account(s) designated by the Distributor. If the Distributor shall default on its obligation to deliver the Shares on any Settlement Date, subject to the terms of Section 5 herein, the Distributor shall (A) hold the Agent harmless against any reasonable loss, claim or damage

- 2 -

arising from or as a result of such default by the Distributor and (B) pay the Agent any commission to which it would otherwise be entitled absent such default. If the Agent breaches this Agreement by failing to deliver proceeds on any Settlement Date for the Shares delivered by the Distributor, subject to the terms of Section 5 herein, the Agent shall (A) hold the Distributor harmless against any reasonable loss, claim or damage arising from or as a result of such default by the Agent, (B) deliver such proceeds to the Distributor as soon as practicable and (C) pay the Distributor interest based on the effective overnight Federal Funds rate.

(g) In connection with this Agreement and the Offerings, the Distributor shall, no more than once per calendar quarter in which the Fund and the Distributor have requested, or anticipate requesting, that the Agent sell Shares pursuant to an Offering, provide to the Agent such certificates and other documents, in any case, as the Agent may reasonably request upon reasonable notice (but in no event upon notice of less than five business days) relating to authorization, capacity, enforceability and compliance matters. Any such certifications shall be made as of the end of the calendar quarter immediately preceding the calendar quarter in which such request by the Agent is made.

(h) In connection with this Agreement and the Offerings, the Agent will promptly notify the Distributor of any material non-confidential claim or complaint, any material enforcement action or other material proceeding by a regulatory authority with respect to the Fund, the Shares or the Offerings against or directed at or to the Agent or its principals, affiliates, officers, directors, employees or agents, or any person who controls the Agent, within the meaning of Section 15 of the Securities Act.

(i) In connection with this Agreement and the Offerings, the Agent will promptly notify the Distributor of any examination by any regulatory agency or self-regulatory organization that has resulted in a material compliance deficiency in connection with the Offerings.

The Agent confirms that (i) the Agent’s name under Item 1.g. of Part I and Item 5 of Part II of the Prospectus and (ii) the eighth paragraph under Item 5 of Part II of the Prospectus was the only information furnished in writing to the Distributor or the Fund by or on behalf of the Agent expressly for use in the Registration Statement or Prospectus.

(g) Based upon the representations made by the Fund to the Distributor in the Distribution Agreement, (i) the Shares have been duly and validly authorized and, when issued and delivered against payment therefor as provided herein, will be duly and validly issued, fully paid and non-assessable (except as described below and in the Registration Statement) and free of statutory and contractual preemptive rights, resale rights, rights of first refusal and similar rights; (ii) the Shares, when issued and delivered against payment therefor as provided herein, will be free of any restriction upon the voting or transfer thereof pursuant to the Fund’s agreement and declaration of trust or bylaws or any agreement or other instrument to which the Fund is a party; (iii) the capital stock of the Fund, including the Shares, conforms in all material respects to each description thereof, if any, contained or incorporated by reference in the Registration Statement or the Prospectus; (iv) the certificates for the Shares, if any, are in due and proper form; and (v) the Fund is in material compliance with the rules of the Stock Exchange, including, without limitation, the requirements for continued listing of the Common Shares on the Stock Exchange and the Fund has not received any written notice from the Stock Exchange regarding the delisting of the Common Shares from the Stock Exchange.

(h) The Distributor has full corporate power and authority to enter into this Agreement and the transactions contemplated hereby. This Agreement has been duly authorized, executed and delivered by the Distributor. Assuming due authorization, execution and delivery of this Agreement by the Agent, this Agreement constitutes a valid and binding agreement of the Distributor and is enforceable against the Distributor in accordance with its terms, except as the enforceability hereof and thereof may be limited by applicable bankruptcy, insolvency, reorganization and similar laws affecting creditors’ rights generally and moratorium laws in effect from time to time and by equitable principles restricting the availability of equitable remedies.

(i) Based upon the representations made by the Fund to the Distributor in the Distribution Agreement, no approval, authorization, consent or order of or filing with any federal, state, local or foreign governmental or regulatory commission, board, body, authority or agency, or of or with any self-regulatory organization or other non-governmental regulatory authority (including, without limitation, the Stock Exchange), or approval of the shareholders of the Fund that has not already been obtained, is required in connection with the issuance and sale of the Shares or the consummation by the Fund of the transactions contemplated hereby, other than (i) the registration of the Shares under the Securities Act, which has been effected, (ii) the listing of the Shares with the Stock Exchange, upon official notice of issuance, (iii) any necessary qualification under the securities or blue sky laws of the various jurisdictions in which the Shares are being offered by the Distributor or (iv) any necessary qualification pursuant to the rules of the Financial Industry Regulatory Authority, Inc.

- 6 -

(a) The Agent has full corporate power and authority to enter into this Agreement and the transactions contemplated hereby. This Agreement has been duly authorized, executed and delivered by the Agent. Assuming due authorization, execution and delivery by the Distributor, this Agreement constitutes a valid and binding agreement of the Agent and is enforceable against the Agent in accordance with its terms, except as the enforceability hereof and thereof may be limited by applicable bankruptcy, insolvency, reorganization and similar laws affecting creditors’ rights generally and moratorium laws in effect from time to time and by equitable principles restricting the availability of equitable remedies.

(b) The Agent Provided Information is or will be complete and accurate in all material respects and does not or will not, as from time to time amended or supplemented, include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(c) The Agent has adopted and implemented written policies and procedures reasonably designed to prevent violation of federal and state securities laws, including policies and procedures that provide oversight of compliance by each registered representative of the Agent.

SECTION 4. Additional Covenants.

(a) The Agent hereby confirms that it is actually engaged in the investment banking and securities business and is a member in good standing with FINRA and hereby agrees that it will undertake to comply with all applicable FINRA rules (as amended from time to time, including without limitation, any successor provision) in connection with acting as sub-placement agent for the sale of the Shares. The Agent further agrees that in acting as sub-placement agent for the sale of the Shares, it will comply with all applicable laws, rules and regulations, including the applicable provisions of the Securities Act and the Exchange Act, the applicable rules and regulations of the Commission thereunder, and the applicable rules and regulations of any state or any securities exchange or self-regulatory organization having jurisdiction over the relevant Offering.

(b) The Agent hereby agrees that in acting as sub-placement agent for the sale of the Shares, it will not use, authorize use of, refer to, or participate in the planning for use of any written communication (as defined in Rule 405 under the Securities Act) concerning any Offering, other than the Prospectus. The Agent further agrees that in acting as sub-placement agent for the sale of the Shares, it is not authorized by the Distributor or the Fund or any other seller of the Shares offered pursuant to the Prospectus to give any information or to make any representation not contained in the Prospectus in connection with the sale of such Shares.

(c) The Distributor shall not be under any obligation to the Agent except for obligations assumed hereunder or in writing by the Distributor in connection with any Offering. Nothing contained herein or in any communication in writing from us shall constitute the Distributor and the Agent an association or partners with one another. If such parties should be deemed to constitute a partnership for Federal income tax purposes, then the Agent elects to be excluded from the application of Subchapter K, Chapter 1, Subtitle A of the Internal Revenue

- 7 -

Code of 1986 and agrees not to take any position inconsistent with that election. The Agent authorizes the Distributor, in its discretion, to execute and file on its behalf such evidence of that election as may be required by the Internal Revenue Service. In connection with any Offering, each party shall be liable for its proportionate amount of any tax, claim, demand or liability that may be asserted against it alone, based upon the claim that either of them constitutes an association, an unincorporated business or other entity, including, in each case, its proportionate amount of any expense incurred in defending against any such tax, claim, demand or liability.

(d) The parties acknowledge and agree that all share related numbers contained in this Agreement shall be adjusted to take into account any stock split effected with respect to the Shares.

(e) The Agent shall at all times comply with the offering requirements as set forth herein and under the heading “Plan of Distribution” in the Prospectus.

SECTION 5. Indemnification and Contribution.

(a) The Distributor agrees to indemnify, defend and hold harmless the Agent, its partners, directors and officers, and any person who controls the Agent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any reasonable loss, damage, expense, liability or claim (including the reasonable cost of investigation) which the Agent or any such person may incur under the Securities Act, the 1940 Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim (or any actions or proceedings in respect thereof) arises out of or is based upon (i) any material breach of any representation, warranty, covenant or agreement of the Distributor contained in this Agreement, (ii) any material violation by the Distributor of any law, rule or regulation (including any rule of any self-regulatory organization) applicable to the Offerings, or (iii) any untrue statement or alleged untrue statement of a material fact appearing in the Registration Statement or Prospectus or omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading, except to the extent such statements were included in the Registration Statement or Prospectus in reliance upon and in conformity with the Agent Provided Information.

(b) The Agent agrees to indemnify, defend and hold harmless the Distributor, the Fund, their partners, trustees, directors and officers, and any person who controls the Distributor or the Fund within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which the Distributor, the Fund or any such other person may incur under the Securities Act, the 1940 Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim (or any actions or proceedings in respect thereof) arises out of or is based upon (i) any material breach of any representation, warranty, covenant or agreement of the Agent contained in this Agreement or (ii) any material violation by the Agent of any law, rule or regulation (including any rule of any self-regulatory organization), or (iii) any untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement or the Prospectus in reliance upon and in conformity with the Agent Provided Information.

- 8 -

(c) An indemnified person under Section 5 of this Agreement (the “Indemnified Party”) shall give written notice to the other party (the “Indemnifying Party”) of any loss, damage, expense, liability or claim in respect of which the Indemnifying Party has a duty to indemnify such Indemnified Party under Section 5(a) or (b) of this Agreement (a “Claim”), specifying in reasonable detail the nature of the loss, damage, expense, liability or claim for which indemnification is sought, except that any delay or failure so to notify such Indemnifying Party shall only relieve such Indemnifying Party of its obligations hereunder to the extent, if at all, that such Indemnifying Party is actually prejudiced by reason of such delay or failure.

(d) If a Claim results from any action, suit or proceeding brought or asserted against an Indemnified Party, the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses. The Indemnified Party shall have the right to employ separate counsel in such action, suit or proceeding and participate in such defense thereof, but the fees and expenses of such separate counsel shall be at the expense of the Indemnified Party unless (i) the Indemnifying Party has agreed in writing to pay such fees and expenses, (ii) the Indemnifying Party has failed within a reasonable time to assume the defense and employ counsel or (iii) the named parties to any such action, suit or proceeding (including any impleaded parties) include both such Indemnified Party and Indemnifying Party and such Indemnified Party shall have been advised by its counsel that representation of such Indemnified Party and Indemnifying Party by the same counsel would be inappropriate under applicable standards of professional conduct (whether or not such representation by the same counsel has been proposed) due to actual or potential differing interests between the Indemnifying Party and the Indemnified Party (in which case the Indemnifying Party shall not have the right to assume the defense of such action, suit or proceeding on behalf of such Indemnified Party). It is understood, however, that the Indemnifying Party shall, in connection with any one action, suit or proceeding or separate but substantially similar or related actions, suits or proceedings in the same jurisdiction arising out of the same general allegations or circumstances be liable for the reasonable fees and expenses of only one separate firm of attorneys (in addition to any local counsel) at any time for all such Indemnified Parties not having actual or potential differing interests with the Indemnifying Party or among themselves, which firm shall be designated in writing by an authorized representative of such parties and that all such fees and expenses shall be reimbursed promptly as they are incurred. The Indemnifying Party shall not be liable for any settlement of any such action, suit or proceeding effected without its written consent, but if settled with such written consent or if there be a final judgment for the plaintiff in any such action, suit or proceeding, the Indemnifying Party agrees to indemnify and hold harmless any Indemnified Party from and against any loss, liability, damage or expense by reason by such settlement or judgment.

(e) With respect to any Claim not within Paragraph (d) of Section 5 hereof, the Indemnifying Party shall have 20 days from receipt of notice from the Indemnified Party of such Claim within which to respond thereto. If the Indemnifying Party does not respond within such twenty-day period, it shall be deemed to have accepted responsibility to make payment and shall have no further right to contest the validity of such Claim. If the Indemnifying Party notifies the Indemnified Party within such twenty-day period that it rejects such Claim in whole or in part, the Indemnified Party shall be free to pursue such remedies as may be available to the Indemnified Party under applicable law.

- 9 -

(f) If the indemnification provided for in this Section 5 is unavailable to an Indemnified Party or insufficient to hold an Indemnified Party harmless in respect of any losses, damages, expenses, liabilities or claims referred to therein, then each applicable Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, damages, expenses, liabilities or claims in such proportion as is appropriate to reflect (i) the relative benefits received by the Indemnified Party, on the one hand, and the Indemnifying Party, on the other hand, from the offering of the Shares; or (ii) if, but only if, the allocation provided for in clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Indemnified Party, on the one hand, and of the Indemnifying Party, on the other, in connection with any statements or omissions or other matters which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. The relative benefits received by the Distributor, on the one hand, and the Agent, on the other, shall be deemed to be in the same respective proportions as the total compensation received by the Distributor from sales of the Shares bears to the total compensation received by the Agent from sales of the Shares. The relative fault of the parties hereto shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by such party, on one hand, or by the other party, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party hereto as a result of the losses, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 5 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this subsection (f). No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Notwithstanding the foregoing provisions of this subsection (f), the Agent shall not be required to contribute any amount in excess of the commissions received by it under this Agreement.

(g) The indemnity and contribution agreements contained in this Section 5 and the covenants, warranties and representations of the parties contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the Agent, its partners, directors or officers or any person (including each partner, officer or director of such person) who controls the Agent within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, or by or on behalf of the Distributor, its directors or officers or any person who controls the Distributor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the issuance and delivery of the Shares.

(h) IN NO EVENT WILL ANY PARTY TO THIS AGREEMENT BE LIABLE TO ANY OTHER PERSON OR ANY THIRD PARTY FOR ANY CONSEQUENTIAL, INCIDENTAL, SPECIAL OR INDIRECT DAMAGES (INCLUDING BUT NOT LIMITED TO LOST PROFITS), EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES.

- 10 -

SECTION 6. Termination.

(a) This Agreement shall continue in full force and effect until terminated by either party by five days’ written notice to the other party; provided, that if this Agreement has become effective with respect to any Offering pursuant to this Agreement, this Agreement may not be terminated by either party with respect to such Offering.

(b) This Agreement shall remain in full force and effect unless terminated pursuant to Section 6(a) above or otherwise by mutual agreement of the parties; provided that any such termination by mutual agreement shall in all cases be deemed to provide that Section 5 shall remain in full force and effect.

(c) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that in any event such termination shall not be effective until any earlier than the close of business on the fifth day after receipt of such notice by the Distributor or the Agent, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of the Shares, such sale shall settle in accordance with the provisions of Section 1 of this Agreement.

No other person, partnership, association or corporation (including a purchaser, as such purchaser, from the Distributor) shall acquire or have any right under or by virtue of this Agreement.

- 11 -

SECTION 9. No Fiduciary Relationship. The Distributor hereby acknowledges that the Agent is acting solely as sub-placement agent in connection with the sale of the Shares and that the Agent is acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s length basis, and in no event do the parties intend that the Agent act or be responsible as a fiduciary to the Distributor or the Fund, their respective management, shareholders or creditors, or any other person in connection with any activity that the Agent may undertake or have undertaken in furtherance of the sale of the Shares, either before or after the date hereof.

Ladies and Gentlemen:

We have acted as special Delaware counsel to BlackRock Science and Technology Trust, a Delaware statutory trust (the “Trust”), in connection with certain matters of Delaware law relating to the issuance of up to 13,000,000 shares (the “Offered Shares”) of the Trust’s common shares of beneficial interest, par value $0,001 per share pursuant to the Registration Statement (as defined below). Capitalized terms used herein and not otherwise herein defined are used as defined in the Agreement and Declaration of Trust of the Trust dated as of August 13, 2014 (the “Governing Instrument”).

In rendering this opinion, we have examined and relied on copies of the following documents in the forms provided to us: the Trust’s Registration Statement on Form N-2 (Registration Nos. 333-233028 and 811-22991) as filed on August 5, 2019 with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), and under the Investment Company Act of 1940, as amended (the “Investment Company Act”), as amended by Pre-Effective Amendment No. 1 under the Securities Act and Amendment No. 5 under the Investment Company Act on Form N-2/A of the Trust filed with the Commission on September 18, 2019 (as so amended, the “Registration Statement”), including the Prospectus of the Trust included in the Registration Statement (the “Prospectus”); the Prospectus Supplement of the Trust (the “Prospectus Supplement”), relating to the offering of the Offered Shares, in the form filed with the Commission pursuant to Rule 497 of the Securities Act Rules and Regulations on or about the date hereof; the Sub-Placement Agent Agreement (the “Agent Agreement”) dated on or about the date hereof between BlackRock Investments, LLC and UBS Securities LLC; the Distribution Agreement (the “Distribution Agreement” and together with the Agent Agreement, the “Agreements” and each, individually, an “Agreement”) dated on or about the date hereof between the Trust and BlackRock Investments, LLC; the Certificate of Trust of the Trust as filed in the Office of the Secretary of State of the State of Delaware (the “State Office”) on August 13, 2014 (the “Trust Certificate”); resolutions of the Board of Trustees of the Trust prepared for adoption at a meeting held on June 5, 2019 and June 6, 2019 (the “Resolutions”); the Governing Instrument; the Amended and Restated Bylaws of the Trust effective as of October 28, 2016 (the “Bylaws” and, together with the Governing Instrument, the Registration Statement (including the Prospectus),

the Prospectus Supplement, the Agent Agreement, the Distribution Agreement, the Trust Certificate and the Resolutions, the “Governing Documents”); and a certification of good standing of the Trust obtained as of a recent date from the State Office. In such examinations, we have assumed the genuineness of all signatures, the conformity to original documents of all documents submitted to us as drafts or copies or forms of documents to be executed and the legal capacity of natural persons to complete the execution of documents. We have further assumed for purposes of this opinion: (i) except to the extent set forth in our opinion in paragraph 1 below, the due formation or organization, valid existence and good standing of each entity that is a party to any of the documents reviewed by us under the laws of the jurisdiction of its respective formation or organization; (ii) the due authorization, adoption, execution and delivery by, or on behalf of, each of the parties thereto of the above-referenced documents (including the due adoption by the Board of Trustees of the Resolutions); (iii) that the Trust has and will comply with all Fundamental Policies in connection with conducting its business as described in the Governing Documents; (iv) that the appropriate notation of the names and addresses of, the number of Shares held by, and the consideration paid by, Shareholders will be maintained in the appropriate registers and other books and records of the Trust in connection with the issuance or transfer of Shares; (v) the taking of all appropriate action by the Trustees to designate the series and classes of the Shares and the rights and preferences attributable thereto as contemplated by the Governing Instrument; (vi) that the required consideration for the Shares (including the Offered Shares) has been or will be paid, and the Shares (including the Offered Shares) have been or will be issued, in accordance with the terms, conditions, requirements and procedures of the Governing Documents; (vii) that the activities of the Trust have been and will be conducted in accordance with the terms of the Governing Instrument and the Delaware Statutory Trust Act, 12 Del. C. § 3801 et seq, (the “Delaware Act”); (viii) that no event has occurred that would cause a termination or dissolution of the Trust under the Delaware Act; and (ix) that each of the documents examined by us is in full force and effect, expresses the entire understanding of the parties thereto with respect to the subject matter thereof and has not been amended, supplemented or otherwise modified, except as herein referenced. We have not reviewed any documents other than those identified above in connection with this opinion, and we have assumed that there are no documents, facts or circumstances that are contrary to or inconsistent with the opinions expressed herein. No opinion is expressed with respect to the requirements of, or compliance with, federal or state securities or blue sky laws. In addition, we express no opinion with respect to the Registration Statement (including the Prospectus), or any other offering materials relating to any Shares. As to any fact material to our opinions, other than those assumed, we have relied without independent investigation on the above-referenced documents and on the accuracy, as of the date hereof, of the matters therein contained.

Based on and subject to the foregoing, and limited in all respects to matters of Delaware law, it is our opinion that:

1.    The Trust is a duly formed Delaware statutory trust, validly existing and in good standing under the laws of the State of Delaware with requisite statutory trust power and authority to own, lease and operate its properties and to conduct its business as described in the Prospectus.

2.    The Offered Shares have been duly authorized by the Trust for issuance and, when duly entered into the stock record books of the Trust and issued and delivered by the Trust in accordance with the terms, conditions, requirements and procedures set forth in the Governing Documents against payment therefor of the consideration set forth in the Agreements, will be validly issued, fully paid and non-assessable Shares (except to the extent that under Section 3.8 of the Governing Instrument, the Trustees have the power to cause each Shareholder or each Shareholder of any particular series to pay directly, in advance or arrears, for certain charges of the Trust’s custodian or transfer, Shareholder servicing or similar agent, a pro rata amount as defined from time to time by the Trustees, by setting off such charges due from such Shareholder from declared but unpaid dividends or distributions owed such Shareholder and/or by reducing the number of Shares in the account of such Shareholder by that number of full and/or fractional Shares which represents the outstanding amount of such charges due from such Shareholder).

3.    Under the Governing Instrument and the Delaware Act, the issuance of the Offered Shares is not subject to any preemptive rights or any other similar rights of the Shareholders to subscribe to any additional Shares.

We hereby consent to the filing of a copy of this opinion with the Commission as an exhibit to the Registration Statement. In giving this consent, we do not hereby admit that we come within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission thereunder. This opinion speaks only as of the date hereof and is based on our understandings and assumptions as to present facts, and on the application of Delaware law as the same exist on the date hereof, and we undertake no obligation to update or supplement this opinion after the date hereof for the benefit of any person or entity (including any Shareholder or any person or entity granted reliance in the following sentence) with respect to any facts or circumstances that may hereafter come to our attention or any changes in facts or law that may hereafter occur or take effect. This opinion is intended solely for the benefit of the Trust and the Shareholders in connection with the matters contemplated hereby and may not be relied upon by any other person or entity, or for any other purpose, without our prior written consent; provided, that in the event that Willkie Farr & Gallagher LLP delivers its opinion to the Trust on or about the date hereof, which opinion addresses any matters of Delaware law addressed herein, it may rely on this opinion in connection therewith.
