Exhibit 10.4

 

INDEMNITY AGREEMENT

 

THIS
INDEMNITY AGREEMENT (this “Agreement”) is made as of [●], 2020, by and between Vector
Acquisition Corporation, a Cayman Islands exempted company (the “Company”), and                                      
(“Indemnitee”).

 

WHEREAS,
highly competent persons have become more reluctant to serve publicly-held corporations as directors, officers or in
other capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate
risks of claims and actions against them arising out of their service to and activities on behalf of such corporations;

 

WHEREAS,
the Board of Directors of the Company (the “Board”) has determined that, in order to attract
and retain qualified individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance
to protect persons serving the Company and its subsidiaries from certain liabilities. The amended and restated memorandum and articles
of association of the Company (the “Articles”) provide for the indemnification of the officers and directors
of the Company. Indemnitee may also be entitled to indemnification pursuant to applicable Cayman Islands law. The Articles provide
that the indemnification provisions set forth therein are not exclusive, and thereby contemplate that contracts may be entered
into between the Company and members of the Board, officers and other persons with respect to indemnification, hold harmless, exoneration,
advancement and reimbursement rights;

 

WHEREAS,
the uncertainties relating to such insurance and to indemnification have increased the difficulty of attracting and
retaining such persons;

 

WHEREAS,
the Board has determined that the increased difficulty in attracting and retaining such persons is detrimental to the
best interests of the Company’s shareholders and that the Company should act to assure such persons that there will be increased
certainty of such protection in the future;

 

WHEREAS,
it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, hold harmless,
exonerate and to advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that they will
serve or continue to serve the Company free from undue concern that they will not be so protected against liabilities;

 

WHEREAS,
this Agreement is a supplement to and in furtherance of the Articles of the Company and any resolutions adopted pursuant
thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; and

 

WHEREAS, Indemnitee
may not be willing to serve as an officer or director without adequate protection, and the Company desires Indemnitee to serve
in such capacity. Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the Company
on the condition that he or she be so indemnified.

 

NOW,
THEREFORE, in consideration of the premises and the covenants contained herein and subject to the provisions of the
letter agreement dated as of [●], 2020, the Company and Indemnitee do hereby covenant and agree as follows:

 

     

     

    

 

	1.	SERVICES TO THE COMPANY

 

In consideration of the Company’s
covenants and obligations hereunder, Indemnitee will serve or continue to serve as an officer, director, advisor, key employee
or in any other capacity of the Company, as applicable, for so long as Indemnitee is duly elected or appointed or retained or until
Indemnitee tenders his or her resignation or until Indemnitee is removed. The foregoing notwithstanding, this Agreement shall continue
in full force and effect after Indemnitee has ceased to serve as a director, officer, advisor, key employee or in any other capacity
of the Company, as provided in Section 17. This Agreement, however, shall not impose any obligation on Indemnitee or the Company
to continue Indemnitee’s service to the Company beyond any period otherwise required by law or by other agreements or commitments
of the parties, if any.

serving in such capacity as a director, officer, employee, advisor, fiduciary or other official of another corporation, partnership,
limited liability company, joint venture, trust or other enterprise at the request of, for the convenience of, or to represent

securities by any Person results solely from a reduction in the aggregate number of outstanding shares of securities entitled to

were the Beneficial Owners of securities entitled to vote generally in the election of directors immediately prior to such Business
Combination beneficially own, directly or indirectly, more than 51% of the combined voting power of the then outstanding securities

limitation, a corporation which as a result of such transaction owns the Company or all or substantially all of the Company’s
assets either directly or through one or more Subsidiaries) in substantially the same proportions as their ownership immediately
prior to such Business Combination, of the securities entitled to vote generally in the election of directors; (2) other than
an affiliate of the Sponsor, no Person (excluding any corporation resulting from such Business Combination) is the Beneficial Owner,
directly or indirectly, of 15% or more of the combined voting power of the then outstanding securities entitled to vote generally
in the election of directors of the surviving corporation except to the extent that such ownership existed prior to the Business
Combination; and (3) at least a majority of the board of directors of the corporation resulting from such Business Combination

	3.	INDEMNITY IN THIRD-PARTY PROCEEDINGS

 

To the fullest extent permitted by applicable
law, the Company shall indemnify, hold harmless and exonerate Indemnitee in accordance with the provisions of this Section 3
if Indemnitee was, is, or is threatened to be made, a party to or a participant (as a witness, deponent or otherwise) in any Proceeding,
other than a Proceeding by or in the right of the Company to procure a judgment in its favor, by reason of Indemnitee’s Corporate
Status. Pursuant to this Section 3, Indemnitee shall be indemnified, held harmless and exonerated against all Expenses,
judgments, liabilities, fines, penalties and amounts paid in settlement (including all interest, assessments and other charges
paid or payable in connection with or in respect of such Expenses, judgments, liabilities, fines, penalties and amounts paid in
settlement) actually, and reasonably incurred by Indemnitee or on his or her behalf in connection with such Proceeding or any claim,
issue or matter therein, if Indemnitee acted in good faith and in a manner he or she reasonably believed to be in or not opposed
to the best interests of the Company and, in the case of a criminal Proceeding, had no reasonable cause to believe that his or
her conduct was unlawful; provided, in no event shall Indemnitee be entitled to be indemnified, held harmless or advanced any amounts
hereunder in respect of any Expenses, judgments, liabilities, fines, penalties and amounts paid in settlement (if any) that Indemnitee
may incur by reason of his or her own actual fraud or intentional misconduct. Indemnitee shall not be found to have committed actual
fraud or intentional misconduct for any purpose of this Agreement unless or until a court of competent jurisdiction shall have
made a finding to that effect.

 

	4.	INDEMNITY IN PROCEEDINGS BY OR IN THE RIGHT OF THE COMPANY

 

To the fullest extent permitted by applicable
law, the Company shall indemnify, hold harmless and exonerate Indemnitee in accordance with the provisions of this Section 4
if Indemnitee was, is, or is threatened to be made, a party to or a participant (as a witness, deponent or otherwise) in any Proceeding
by or in the right of the Company to procure a judgment in its favor by reason of Indemnitee’s Corporate Status. Pursuant
to this Section 4, Indemnitee shall be indemnified, held harmless and exonerated against all Expenses actually and reasonably
incurred by him or her or on his or her behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee
acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company.
No indemnification, hold harmless or exoneration for Expenses shall be made under this Section 4 in respect of any claim,
issue or matter as to which Indemnitee shall have been finally adjudged by a court of competent jurisdiction to be liable to the
Company, unless and only to the extent that any court in which the Proceeding was brought or the Delaware Court shall determine
upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee
is fairly and reasonably entitled to indemnification, to be held harmless or to exoneration.

 

    6

     

    

 

	5.	INDEMNIFICATION FOR EXPENSES OF A PARTY WHO IS WHOLLY OR PARTLY SUCCESSFUL

 

Notwithstanding any other provisions of
this Agreement, but subject to Section 27, to the extent that Indemnitee was or is, by reason of Indemnitee’s Corporate
Status, a party to (or a participant in) and is successful, on the merits or otherwise, in any Proceeding or in defense of any
claim, issue or matter therein, in whole or in part, the Company shall, to the fullest extent permitted by applicable law, indemnify,
hold harmless and exonerate Indemnitee against all Expenses actually and reasonably incurred by him or her in connection therewith.
If Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but
less than all claims, issues or matters in such Proceeding, the Company shall, to the fullest extent permitted by applicable law,
indemnify, hold harmless and exonerate Indemnitee against all Expenses actually and reasonably incurred by him or her or on his
or her behalf in connection with each successfully resolved claim, issue or matter. If Indemnitee is not wholly successful in such
Proceeding, the Company also shall, to the fullest extent permitted by applicable law, indemnify, hold harmless and exonerate Indemnitee
against all Expenses reasonably incurred in connection with a claim, issue or matter related to any claim, issue, or matter on
which Indemnitee was successful. For purposes of this Section 5 and without limitation, the termination of any claim, issue
or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim,
issue or matter.

 

	6.	INDEMNIFICATION FOR EXPENSES OF A WITNESS

 

Notwithstanding any other provision of this
Agreement, but subject to Section 27, to the extent that Indemnitee is, by reason of his or her Corporate Status, a witness
or deponent in any Proceeding to which Indemnitee is not a party or threatened to be made a party, he or she shall, to the fullest
extent permitted by applicable law, be indemnified, held harmless and exonerated against all Expenses actually and reasonably incurred
by him or her or on his or her behalf in connection therewith.

 

	7.	ADDITIONAL INDEMNIFICATION, HOLD HARMLESS AND EXONERATION RIGHTS

 

Notwithstanding any limitation in Sections
3, 4 or 5, but subject to Section 27, the Company shall, to the fullest extent permitted by applicable law, indemnify, hold
harmless and exonerate Indemnitee if Indemnitee is a party to or threatened to be made a party to any Proceeding (including a Proceeding
by or in the right of the Company to procure a judgment in its favor) against all Expenses, judgments, fines, penalties and amounts
paid in settlement (including all interest, assessments and other charges paid or payable in connection with or in respect of such
Expenses, judgments, fines, penalties and amounts paid in settlement) actually and reasonably incurred by Indemnitee in connection
with the Proceeding. No indemnification, hold harmless or exoneration rights shall be available under this Section 7 on account
of Indemnitee’s conduct which constitutes a breach of Indemnitee’s duty of loyalty to the Company or its shareholders
or is an act or omission not in good faith or which involves intentional misconduct or a knowing violation of the law.

 

	8.	CONTRIBUTION IN THE EVENT OF JOINT LIABILITY

 

	(a)	To the fullest extent permissible under applicable law, if the indemnification, hold harmless and/or exoneration rights provided
for in this Agreement are unavailable to Indemnitee in whole or in part for any reason whatsoever, the Company, in lieu of indemnifying,
holding harmless or exonerating Indemnitee, shall pay, in the first instance, the entire amount incurred by Indemnitee, whether
for judgments, liabilities, fines, penalties, amounts paid or to be paid in settlement and/or for Expenses, in connection with
any Proceeding without requiring Indemnitee to contribute to such payment, and the Company hereby waives and relinquishes any right
of contribution it may have at any time against Indemnitee.

 

    7

     

    

 

	(b)	The Company shall not enter into any settlement of any Proceeding in which the Company is jointly liable with Indemnitee (or
would be if joined in such Proceeding) unless such settlement provides for a full and final release of all claims asserted against
Indemnitee.

 

	(c)	The Company hereby agrees to fully indemnify, hold harmless and exonerate Indemnitee from any claims for contribution which
may be brought by officers, directors or employees of the Company other than Indemnitee who may be jointly liable with Indemnitee.
Indemnitee shall seek payments or advances from the Company only to the extent that such payments or advances are unavailable from
any insurance policy of the Company covering Indemnitee.

 

	9.	EXCLUSIONS

 

Notwithstanding
any provision in this Agreement, but subject to Section 27, the Company shall not be obligated under this Agreement to make
any indemnification, advance Expenses, hold harmless or exoneration payment in connection with any claim made against Indemnitee:

 

	(a)	for which payment has actually been received by or on behalf of Indemnitee under any insurance policy or other indemnity or
advancement provision, except with respect to any excess beyond the amount actually received under any insurance policy, contract,
agreement, other indemnity or advancement provision or otherwise;

 

	(b)	for an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company
within the meaning of Section 16(b) of the Exchange Act (or any successor rule) or similar provisions of state statutory
law or common law; or

 

	(c)	except as otherwise provided in Sections 14(f) and (g) hereof, prior to a Change in Control, in connection with any
Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated
by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board authorized
the Proceeding (or any part of any Proceeding) prior to its initiation or (ii) the Company provides the indemnification, hold
harmless or exoneration payment, in its sole discretion, pursuant to the powers vested in the Company under applicable law.

 

    8

     

    

 

	10.	ADVANCES OF EXPENSES; DEFENSE OF CLAIM

 

	(a)	Notwithstanding any provision of this Agreement to the contrary, but subject to Section 27, and to the fullest extent
not prohibited by applicable law, the Company shall pay the Expenses incurred by Indemnitee (or reasonably expected by Indemnitee
to be incurred by Indemnitee within three months) in connection with any Proceeding within ten (10) days after the receipt
by the Company of a statement or statements requesting such advances from time to time, prior to the final disposition of any Proceeding.
Advances shall, to the fullest extent permitted by law, be unsecured and interest free. Advances shall, to the fullest extent permitted
by law, be made without regard to Indemnitee’s ability to repay the Expenses and without regard to Indemnitee’s ultimate
entitlement to be indemnified, held harmless or exonerated under the other provisions of this Agreement. Advances shall include
any and all reasonable Expenses incurred pursuing a Proceeding to enforce this right of advancement, including Expenses incurred
preparing and forwarding statements to the Company to support the advances claimed. To the fullest extent required by applicable
law, such payments of Expenses in advance of the final disposition of the Proceeding shall be made only upon the Company’s
receipt of an undertaking, by or on behalf of Indemnitee, to repay the advanced amounts to the extent that it is ultimately determined
that Indemnitee is not entitled to be indemnified by the Company under the provisions of this Agreement, the Articles, applicable
law or otherwise. If it shall be determined by a final judgment or other final adjudication that Indemnitee was not so entitled
to indemnification, any advancement shall be returned to the Company (without interest) by the Indemnitee. This Section 10(a) shall
not apply to any claim made by Indemnitee for which an indemnification, hold harmless or exoneration payment is excluded pursuant
to Section 9, but shall apply to any Proceeding referenced in Section 9(b) prior to a final determination that Indemnitee
is liable therefor.

 

	(b)	The Company will be entitled to participate in the Proceeding at its own expense.

 

	(c)	The Company shall not settle any action, claim or Proceeding (in whole or in part) which would impose any Expense, judgment,
fine, penalty or limitation on Indemnitee without Indemnitee’s prior written consent.

 

	11.	PROCEDURE FOR NOTIFICATION AND APPLICATION FOR INDEMNIFICATION

 

	(a)	Indemnitee agrees to notify promptly the Company in writing upon being served with any summons, citation, subpoena, complaint,
indictment, information or other document relating to any Proceeding, claim, issue or matter therein which may be subject to indemnification,
hold harmless or exoneration rights, or advancement of Expenses covered hereunder. The failure of Indemnitee to so notify the Company
shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement, or otherwise.

 

	(b)	Indemnitee may deliver to the Company a written application to indemnify, hold harmless or exonerate Indemnitee in accordance
with this Agreement. Such application(s) may be delivered from time to time and at such time(s) as Indemnitee deems appropriate
in his or her sole discretion. Following such a written application for indemnification by Indemnitee, Indemnitee’s
entitlement to indemnification shall be determined according to Section 12(a) of this Agreement.

 

    9

     

    

 

	12.	PROCEDURE UPON APPLICATION FOR INDEMNIFICATION

 

	(a)	A determination, if required by applicable law, with respect to Indemnitee’s entitlement to indemnification shall be
made in the specific case by one of the following methods, which shall be at the election of Indemnitee: (i) by a majority
vote of the Disinterested Directors, even though less than a quorum of the Board, (ii) by a committee of such directors designated
by majority vote of such directors, (iii) if there are no Disinterested Directors or if such directors so direct, by Independent
Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee, or (iv) by vote of the shareholders
by ordinary resolution. The Company promptly will advise Indemnitee in writing with respect to any determination that Indemnitee
is or is not entitled to indemnification, including a description of any reason or basis for which indemnification has been denied.
If it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten (10) days
after such determination. Indemnitee shall reasonably cooperate with the person, persons or entity making such determination with
respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable
advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is reasonably
available to Indemnitee and reasonably necessary to such determination. Any costs or Expenses (including reasonable attorneys’
fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall
be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company
hereby agrees to indemnify and to hold Indemnitee harmless therefrom.

 

	(b)	In the event the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 12(a) hereof,
the Independent Counsel shall be selected as provided in this Section 12(b). The Independent Counsel shall be selected by
Indemnitee (unless Indemnitee shall request that such selection be made by the Board), and Indemnitee shall give written notice
to the Company advising it of the identity of the Independent Counsel so selected and certifying that the Independent Counsel so
selected meets the requirements of “Independent Counsel” as defined in Section 2 of this Agreement.
If the Independent Counsel is selected by the Board, the Company shall give written notice to Indemnitee advising him or her of
the identity of the Independent Counsel so selected and certifying that the Independent Counsel so selected meets the requirements
of “Independent Counsel” as defined in Section 2 of this Agreement. In either event, Indemnitee
or the Company, as the case may be, may, within ten (10) days after such written notice of selection shall have been received,
deliver to the Company or to Indemnitee, as the case may be, a written objection to such selection; provided, however, that such
objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent
Counsel” as defined in Section 2 of this Agreement, and the objection shall set forth with particularity the
factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel.
If such written objection is so made and substantiated, the Independent Counsel so selected may not serve as Independent Counsel
unless and until such objection is withdrawn or a court of competent jurisdiction has determined that such objection is without
merit. If, within twenty (20) days after submission by Indemnitee of a written request for indemnification pursuant to Section 11(b) hereof,
no Independent Counsel shall have been selected and not objected to, either the Company or Indemnitee may petition the Delaware
Court for resolution of any objection which shall have been made by the Company or Indemnitee to the other’s selection of
Independent Counsel and/or for the appointment as Independent Counsel of a person selected by the Delaware Court, and the person
with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 12(a) hereof.
Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 14(a) of this Agreement, Independent
Counsel shall be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of
professional conduct then prevailing).

 

    10

     

    

 

	(c)	The Company agrees to pay the reasonable fees and expenses of Independent Counsel and to fully indemnify and hold harmless
such Independent Counsel against any and all Expenses, claims, liabilities and damages arising out of or relating to this Agreement
or its engagement pursuant hereto.

 

	13.	PRESUMPTIONS AND EFFECT OF CERTAIN PROCEEDINGS

 

	(a)	In making a determination with respect to entitlement to indemnification hereunder, the person, persons or entity making such
determination shall presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request
for indemnification in accordance with Section 11(b) of this Agreement, and the Company shall have the burden of proof
to overcome that presumption in connection with the making by any person, persons or entity of any determination contrary to that
presumption. Neither the failure of the Company (including by the Disinterested Directors or Independent Counsel) to have made
a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances
because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by the Disinterested
Directors or Independent Counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action
or create a presumption that Indemnitee has not met the applicable standard of conduct.

 

	(b)	If the person, persons or entity empowered or selected under Section 12 of this Agreement to determine whether Indemnitee
is entitled to indemnification shall not have made a determination within thirty (30) days after receipt by the Company of the
request therefor, the requisite determination of entitlement to indemnification shall, to the fullest extent permitted by law,
be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a misstatement by Indemnitee
of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading,
in connection with the request for indemnification, or (ii) a final judicial determination that any or all such indemnification
is expressly prohibited under applicable law; provided, however, that such 30-day period may be extended for a reasonable time,
not to exceed an additional fifteen (15) days, if the person, persons or entity making the determination with respect to entitlement
to indemnification in good faith requires such additional time for the obtaining or evaluating of documentation and/or information
relating thereto.

 

    11

     

    

 

	(c)	The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or
upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself
adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and
in a manner which he or she reasonably believed to be in or not opposed to the best interests of the Company or, with respect to
any criminal Proceeding, that Indemnitee had reasonable cause to believe that his or her conduct was unlawful.

 

	(d)	For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith if Indemnitee’s
action is based on the records or books of account of the Enterprise, including financial statements, or on information supplied
to Indemnitee by the directors, manager, or officers of the Enterprise in the course of their duties, or on the advice of legal
counsel for the Enterprise, its Board, any committee of the Board or any director, trustee, general partner, manager or managing
member, or on information or records given or reports made to the Enterprise, its Board, any committee of the Board or any director,
trustee, general partner, manager or managing member, by an independent certified public accountant or by an appraiser or other
expert selected by the Enterprise, its Board, any committee of the Board or any director, trustee, general partner, manager or
managing member. The provisions of this Section 13(d) shall not be deemed to be exclusive or to limit in any way the
other circumstances in which Indemnitee may be deemed or found to have met the applicable standard of conduct set forth in this
Agreement.

 

	(e)	The knowledge and/or actions, or failure to act, of any other director, officer, trustee, partner, manager, managing member,
fiduciary, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification
under this Agreement.

 

	14.	REMEDIES OF INDEMNITEE

 

	(a)	In the event that (i) a determination is made pursuant to Section 12 of this Agreement that Indemnitee is not entitled
to indemnification under this Agreement, (ii) advancement of Expenses, to the fullest extent permitted by applicable law,
is not timely made pursuant to Section 10 of this Agreement, (iii) no determination of entitlement to indemnification
shall have been made pursuant to Section 12(a) of this Agreement within thirty (30) days after receipt by the Company
of the request for indemnification, (iv) payment of indemnification is not made pursuant to Sections 5, 6, 7 or the last sentence
of Section 12(a) of this Agreement within ten (10) days after receipt by the Company of a written request therefor,
(v) a contribution payment is not made in a timely manner pursuant to Section 8 of this Agreement, (vi) payment
of indemnification pursuant to Section 3 or 4 of this Agreement is not made within ten (10) days after a determination
has been made that Indemnitee is entitled to indemnification, or (vii) payment to Indemnitee pursuant to any hold harmless
or exoneration rights under this Agreement or otherwise is not made in accordance with this Agreement within ten (10) days
after receipt by the Company of a written request therefor, Indemnitee shall be entitled to an adjudication by the Delaware
Court to such indemnification, hold harmless, exoneration, contribution or advancement rights. Alternatively, Indemnitee,
at his or her option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration
Rules and Mediation Procedures of the American Arbitration Association. Except as set forth herein, the Commercial Arbitration
Rules and Mediation Procedures of the American Arbitration Association shall apply to any such arbitration. The Company shall
not oppose Indemnitee’s right to seek any such adjudication or award in arbitration.

 

    12

     

    

 

	(b)	In the event that a determination shall have been made pursuant to Section 12(a) of this Agreement that Indemnitee
is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 14 shall be
conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of
that adverse determination.

 

	(c)	In any judicial proceeding or arbitration commenced pursuant to this Section 14, Indemnitee shall be presumed to
be entitled to be indemnified, held harmless, exonerated to receive advancement of Expenses under this Agreement and the Company
shall have the burden of proving Indemnitee is not entitled to be indemnified, held harmless, exonerated and to receive advancement
of Expenses, as the case may be, and the Company may not refer to or introduce into evidence any determination pursuant to Section 12(a) of
this Agreement adverse to Indemnitee for any purpose. If Indemnitee commences a judicial proceeding or arbitration pursuant to
this Section 14, Indemnitee shall not be required to reimburse the Company for any advances pursuant to Section 10
until a final determination is made with respect to Indemnitee’s entitlement to indemnification (as to which all rights of
appeal have been exhausted or lapsed).

 

	(d)	If a determination shall have been made pursuant to Section 12(a) of this Agreement that Indemnitee is entitled to
indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant
to this Section 14, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary
to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a
prohibition of such indemnification under applicable law.

 

	(e)	The Company shall be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Section 14
that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court
or before any such arbitrator that the Company is bound by all the provisions of this Agreement.

 

	(f)	The Company shall indemnify and hold harmless Indemnitee to the fullest extent permitted by law against all Expenses and, if
requested by Indemnitee, shall (within ten (10) days after the Company’s receipt of such written request) pay to Indemnitee,
to the fullest extent permitted by applicable law, such Expenses which are incurred by Indemnitee in connection with any judicial
proceeding or arbitration brought by Indemnitee: (i) to enforce his or her rights under, or to recover damages for breach
of, this Agreement or any other indemnification, hold harmless, exoneration, advancement or contribution agreement or provision
of the Articles now or hereafter in effect; or (ii) for recovery or advances under any insurance policy maintained by any
person for the benefit of Indemnitee, regardless of the outcome and whether Indemnitee ultimately is determined to be entitled
to such indemnification, hold harmless or exoneration right, advancement, contribution or insurance recovery, as the case may be
(unless such judicial proceeding or arbitration was not brought by Indemnitee in good faith).

 

    13

     

    

 

	(g)	Interest shall be paid by the Company to Indemnitee at the legal rate under New York law for amounts which the Company indemnifies,
holds harmless or exonerates, or advances, or is obliged to indemnify, hold harmless or exonerate or advance for the period commencing
with the date on which Indemnitee requests indemnification, to be held harmless, exonerated, contribution, reimbursement or advancement
of any Expenses and ending with the date on which such payment is made to Indemnitee by the Company.

 

	15.	SECURITY

 

Notwithstanding anything herein to the contrary,
but subject to Section 27, to the extent requested by Indemnitee and approved by the Board, the Company may at any time and
from time to time provide security to Indemnitee for the Company’s obligations hereunder through an irrevocable bank line
of credit, funded trust or other collateral. Any such security, once provided to Indemnitee, may not be revoked or released without
the prior written consent of Indemnitee.

 

	16.	NON-EXCLUSIVITY; SURVIVAL OF RIGHTS; INSURANCE; SUBROGATION; PRIORITY OF OBLIGATIONS

 

	(a)	The rights of Indemnitee as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee
may at any time be entitled under applicable law, the Articles, any agreement, a vote of shareholders or a resolution of directors,
or otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right
of Indemnitee under this Agreement in respect of any Proceeding (regardless of when such Proceeding is first threatened, commenced
or completed) or claim, issue or matter therein arising out of, or related to, any action taken or omitted by such Indemnitee in
his or her Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in applicable law, whether
by statute or judicial decision, permits greater indemnification, hold harmless or exoneration rights or advancement of Expenses
than would be afforded currently under the Articles or this Agreement, then this Agreement (without any further action by the parties
hereto) shall automatically be deemed to be amended to require that the Company indemnifies the Indemnitee to the fullest extent
permitted by law. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other
right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing
at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other right or remedy.

 

    14

     

    

 

	(b)	The Articles permit the Company to purchase and maintain insurance or furnish similar protection or make other arrangements
including, but not limited to, providing a trust fund, letter of credit, or surety bond (“Indemnification Arrangements”)
on behalf of Indemnitee against any liability asserted against him or her or incurred by or on behalf of him or in such capacity
as a director, officer, employee or agent of the Company, or arising out of his or her status as such, whether or not the Company
would have the power to indemnify him or her against such liability under the provisions of this Agreement and the Articles. The
purchase, establishment, and maintenance of any such Indemnification Arrangement shall not in any way limit or affect the rights
and obligations of the Company or of Indemnitee under this Agreement except as expressly provided herein, and the execution and
delivery of this Agreement by the Company and Indemnitee shall not in any way limit or affect the rights and obligations of the
Company or the other party or parties thereto under any such Indemnification Arrangement.

 

	(c)	To the extent that the Company maintains an insurance policy or policies providing liability insurance for directors, officers,
trustees, partners, managers, managing members, fiduciaries, employees, or agents of the Company or of any other Enterprise which
such person serves at the request of the Company, Indemnitee shall be covered by such policy or policies in accordance with
its or their terms to the maximum extent of the coverage available for any such director, officer, trustee, partner, managers,
managing member, fiduciary, employee or agent under such policy or policies. If, at the time the Company receives notice from any
source of a Proceeding as to which Indemnitee is a party or a participant (as a witness, deponent or otherwise), the Company has
director and officer liability insurance in effect, the Company shall give prompt notice of such Proceeding to the insurers in
accordance with the procedures set forth in the respective policies. The Company shall thereafter use commercially reasonable efforts
to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such Proceeding in accordance with the
terms of such policies.

 

	(d)	In the event of any payment under this Agreement, the Company, to the fullest extent permitted by law, shall be subrogated
to the extent of such payment to all of the rights of recovery of Indemnitee, who shall execute all papers required and take all
action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit
to enforce such rights. No such payment by the Company shall be deemed to relieve any insurer of its obligations.

 

	(e)	The Company’s obligation to indemnify, hold harmless, exonerate or advance Expenses hereunder to Indemnitee who is or
was serving at the request of the Company as a director, officer, trustee, partner, manager, managing member, fiduciary, employee
or agent of any other Enterprise shall be reduced by any amount Indemnitee has actually received as indemnification, hold harmless
or exoneration payments or advancement of expenses from such Enterprise. Notwithstanding any other provision of this Agreement
to the contrary, but subject to Section 27, (i) Indemnitee shall have no obligation to reduce, offset, allocate, pursue
or apportion any indemnification, hold harmless, exoneration, advancement, contribution or insurance coverage among multiple parties
possessing such duties to Indemnitee prior to the Company’s satisfaction and performance of all its obligations under this
Agreement, and (ii) the Company shall perform fully its obligations under this Agreement without regard to whether Indemnitee
holds, may pursue or has pursued any indemnification, advancement, hold harmless, exoneration, contribution or insurance coverage
rights against any person or entity other than the Company.

 

    15

     

    

 

	(f)	Notwithstanding anything contained herein, the Company is the primary indemnitor, and any indemnification or advancement obligation
of the Sponsor or its affiliates or members or any other Person is secondary.

 

	17.	DURATION OF AGREEMENT

 

All agreements and obligations of the Company
contained herein shall continue during the period Indemnitee serves as a director or officer of the Company or as a director, officer,
trustee, partner, manager, managing member, fiduciary, employee or agent of any other corporation, partnership, joint venture,
trust, employee benefit plan or other Enterprise which Indemnitee serves at the request of the Company and shall continue thereafter
so long as Indemnitee shall be subject to any possible Proceeding (including any rights of appeal thereto and any Proceeding commenced
by Indemnitee pursuant to Section 14 of this Agreement) by reason of his or her Corporate Status, whether or not he or she
is acting in any such capacity at the time any liability or expense is incurred for which indemnification or advancement can be
provided under this Agreement.

 

	18.	SEVERABILITY

 

If any provision or provisions of this Agreement
shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (a) the validity, legality and enforceability
of the remaining provisions of this Agreement (including, without limitation, each portion of any Section, paragraph or sentence
of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal
or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted
by law; (b) such provision or provisions shall be deemed reformed to the extent necessary to conform to applicable law and
to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of
this Agreement (including, without limitation, each portion of any Section, paragraph or sentence of this Agreement containing
any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be
construed so as to give effect to the intent manifested thereby.

 

	19.	ENFORCEMENT AND BINDING EFFECT

 

	(a)	The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it
hereby in order to induce Indemnitee to serve as a director, officer or key employee of the Company, and the Company acknowledges
that Indemnitee is relying upon this Agreement in serving as a director, officer or key employee of the Company.

 

	(b)	Without limiting any of the rights of Indemnitee under the Articles of the Company as they may be amended from time to time,
this Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes
all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter
hereof.

 

    16

     

    

 

	(c)	The indemnification, hold harmless, exoneration and advancement of expenses rights provided by or granted pursuant to this
Agreement shall be binding upon and be enforceable by the parties hereto and their respective successors and assigns (including
any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business and/or
assets of the Company), shall continue as to an Indemnitee who has ceased to be a director, officer, employee or agent of the Company
or a director, officer, trustee, general partner, manager, managing member, fiduciary, employee or agent of any other Enterprise
at the Company’s request, and shall inure to the benefit of Indemnitee and his or her spouse, assigns, heirs, devisees, executors
and administrators and other legal representatives.

 

	(d)	The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise)
to all, substantially all or a substantial part, of the business and/or assets of the Company, by written agreement in form and
substance satisfactory to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform if no such succession had taken place.

 

	(e)	The Company and Indemnitee agree herein that a monetary remedy for breach of this Agreement, at some later date, may be inadequate,
impracticable and difficult of proof, and further agree that such breach may cause Indemnitee irreparable harm. Accordingly, the
parties hereto agree that Indemnitee may, to the fullest extent permitted by law, enforce this Agreement by seeking, among other
things, injunctive relief and/or specific performance hereof, without any necessity of showing actual damage or irreparable harm
and that by seeking injunctive relief and/or specific performance, Indemnitee shall not be precluded from seeking or obtaining
any other relief to which he or she may be entitled. The Company and Indemnitee further agree that Indemnitee shall, to the fullest
extent permitted by law, be entitled to such specific performance and injunctive relief, including temporary restraining orders,
preliminary injunctions and permanent injunctions, without the necessity of posting bonds or other undertaking in connection therewith.
The Company acknowledges that in the absence of a waiver, a bond or undertaking may be required of Indemnitee by a court of competent
jurisdiction, and the Company hereby waives any such requirement of such a bond or undertaking to the fullest extent permitted
by law.

 

	20.	MODIFICATION AND WAIVER

 

No supplement, modification or amendment
of this Agreement shall be binding unless executed in writing by the parties hereto. No waiver of any of the provisions of this
Agreement shall be deemed or shall constitute a waiver of any other provisions of this Agreement nor shall any waiver constitute
a continuing waiver.

this Agreement, to the fullest extent permitted by law, the Company and Indemnitee hereby irrevocably and unconditionally: (a) agree

	23.	IDENTICAL COUNTERPARTS

 

This Agreement may be executed in one or
more counterparts, each of which shall for all purposes be deemed to be an original but all of which together shall constitute

cause of action shall be asserted by or in the right of the Company against Indemnitee, Indemnitee’s spouse, heirs,
executors or personal or legal representatives after the expiration of two years from the date of accrual of such cause of action,
and any claim or cause of action of the Company shall be extinguished and deemed released unless asserted by the timely filing
of a legal action within such two-year period; provided, however, that if any shorter period of limitations is otherwise applicable
to any such cause of action such shorter period shall govern.

 

	26.	ADDITIONAL ACTS

 

If for the validation of any of the provisions
in this Agreement any act, resolution, approval or other procedure is required to the fullest extent permitted by law, the Company
undertakes to cause such act, resolution, approval or other procedure to be affected or adopted in a manner that will enable the
Company to fulfill its obligations under this Agreement.

 

	27.	WAIVER OF CLAIMS TO TRUST ACCOUNT

 

Notwithstanding anything contained herein
to the contrary, Indemnitee hereby agrees that it does not have any right, title, interest or claim of any kind (each, a “Claim”)
in or to any monies in the trust account established in connection with the Company’s initial public offering for the benefit
of the Company and holders of shares issued in such offering, and hereby waives any Claim it may have in the future as a result
of, or arising out of, any services provided to the Company and will not seek recourse against such trust account for any reason
whatsoever. Accordingly, Indemnitee acknowledges and agrees that any indemnification provided hereto will only be able to
be satisfied by the Company if (i) the Company has sufficient funds outside of the Trust Account to satisfy its obligations
hereunder or (ii) the Company consummates a Business Combination.

 

    19

     

    

 

	28.	MAINTENANCE OF INSURANCE

 

The Company shall use commercially reasonable
efforts to obtain and maintain in effect during the entire period for which the Company is obligated to indemnify the Indemnitee
under this Agreement, one or more policies of insurance with reputable insurance companies to provide the officers/directors of
the Company with coverage for losses from wrongful acts and omissions and to ensure the Company’s performance of its indemnification
obligations under this Agreement. The Indemnitee shall be covered by such policy or policies in accordance with its or their terms
to the maximum extent of the coverage available for any such director or officer under such policy or policies. In all such insurance
policies, the Indemnitee shall be named as an insured in such a manner as to provide the Indemnitee with the same rights and benefits
as are accorded to the most favorably insured of the Company’s directors and officers.

Vector Acquisition Partners, L.P.

One Market Street, Steuart Tower, 23rd Floor

San Francisco, California 94105

 

Ladies and Gentlemen:

 

This letter will confirm
our agreement that, commencing on the effective date (the “Effective Date”) of the registration statement
(the “Registration Statement”) for the initial public offering (the “IPO”)
of the securities of Vector Acquisition Corporation (the “Company”) and continuing until the earlier
of (i) the consummation by the Company of an initial business combination and (ii) the Company”s liquidation (in
each case as described in the Registration Statement) (such earlier date hereinafter referred to as the “Termination
Date”), Vector Acquisition Partners, L.P. (the “Sponsor”) shall take steps directly or
indirectly to make available to the Company certain office space, secretarial and administrative services as may be required by
the Company from time to time, situated at One Market Street, Steuart Tower, 23rd Floor, San Francisco, California 94105 (or any
successor location). In exchange therefor, the Company shall pay Sponsor a sum of $10,000 per month on the Effective Date and
continuing monthly thereafter until the Termination Date. Sponsor hereby agrees that it does not have any right, title, interest
or claim of any kind (a “Claim”) in or to any monies that may be set aside in a trust account (the “Trust
Account”) that may be established upon the consummation of the IPO and hereby irrevocably waives any Claim it may
have in the future as a result of, or arising out of, any negotiations, contracts or agreements with the Company and will not
seek recourse against the Trust Account for any reason whatsoever.

 

This letter agreement
constitutes the entire agreement and understanding of the parties hereto in respect of its subject matter and supersedes all prior
understandings, agreements, or representations by or among the parties hereto, written or oral, to the extent they relate in any
way to the subject matter hereof or the transactions contemplated hereby.

 

This letter agreement
may not be amended, modified or waived as to any particular provision, except by a written instrument executed by the parties
hereto.

 

The parties may not
assign this letter agreement and any of their rights, interests, or obligations hereunder without the consent of the other party.

 

This letter agreement
shall be governed by, construed in accordance with, and interpreted pursuant to the laws of the State of New York, without giving
effect to its choice of laws principles that will apply the laws of another jurisdiction.

 

This letter agreement
may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an original but all of which
together shall constitute one and the same agreement. Only one such counterpart signed by the party against whom enforceability
is sought needs to be produced to evidence the existence of this letter agreement.
